The Warrior Worm Ch. 05

Author's Note: The last installment of Warrior Worm is here. This chapter leans pretty heavily into futanari, gender change (both male to female and (quasi) female to male). I tried to put plenty of more conventional material as well, but if the aforementioned themes aren't your jam, you may be disappointed.

On the horizon after this is a succubus focused one-off story, as well as a fantasy story that I've only started brainstorming.

1 - Little Swimmers

Bonnie had no idea what to expect when she slid the sample under the microscope. The cloudy goo certainly looked (and smelled) like semen, but she knew that was impossible. Sure, the parasite had made many uncomfortable changes to her body, but changing her sex outright seemed like too much for her logical brain to accept.

When the scientist looked through the lens, her world turned upside down. She watched in disbelief as little white cells fluttered about, propelled by squiggly tails.

"Sperm?!"

Bonnie felt numb. She tried to wrap her head around the fact that, according to biology, she was now a male.

A hand cupped the swollen masses dangling between Bonnie's legs, causing a tingly flutter to race through her. The wet pressure on the worm intensified. Jack was being a very good sport about everything - too good of a sport.

Those masses really were testicles. They weren't just ornamental, but fully functional. Bonnie could practically feel her new pair churning out sperm and hormones. Her sense of dysphoria intensified.

How is this possible?

Bonnie's rational brain answered her terrified heart: FOXL2.

FOXL2 was a gene that maintained proper function of the ovaries, preventing them from turning into testicular tissue. The parasite must have deactivated the gene as part of numerous genetic changes designed to reshape her into the perfect male host.

"No, I don't want this. I don't want to be a man-ugh!"

Rex swooped in with more of his odious conditioning. Bonnie's resistance to her new sex was met with immediate pain. It wasn't enough that the parasite turned her into a male, it was dead set on making her enjoy the process too.

As the pain faded, the pleasure rushed in to replace it. Jack was sucking Bonnie's worm at a breakneck pace, bringing her right to the edge. The feeling twisted her brain into knots. This was a separate organism, yet it felt so much like a real body part. Not only could Bonnie feel intense, giddy pleasure along the length of it, but she could also feel pain. A few times, Jack had nicked her - nicked the worm with his teeth and she yelped in pain. There was something deeply violating about the level of intimate connection she now felt to a parasitic worm.

Bonnie tried to distract herself by diving back into the clinical study of her infection. Her 'sample' raised many questions. Were the sperm cells actually viable? If so, what genetic code did they carry? The obvious answer was Bonnie's, but the more Bonnie thought about this possibility, the more complex it seemed. Sure, her genes were probably a part of that code, but those genes had clearly been altered. Where did the worm's genes come into play? She had a hunch its DNA was now spliced with her own to create a strange hybrid. Viable or not, what was her sperm count? How did it compare to other males?

This last question made her cringe. It felt so wrong to be lumped in with the opposite sex - formerly opposite sex. For all intents and purposes, Bonnie was now male.

On a second glance, two things stood out to Bonnie. She had looked at other sperm samples way back when she worked for a fertility clinic as an intern. Her sample looked much more crowded compared to the ones she saw previously. There were millions of her little swimmers squirming around.

The second thing Bonnie noticed was even stranger. There were the normal sperm cells, but intermixed with them were larger, beefier versions. These cells had two tails instead of one, allowing them to propel themselves faster, and possessed little spines on their bodies, giving them an aggressive look. At first, the presence of these strange mutants puzzled Bonnie, then it suddenly clicked.

"It's the second infection form!"

"Mmmm mmm?" Jack responded as he sucked her even harder.

When Bonnie first ejaculated into Jack's tight ass, she became overwhelmed with the strangest urge. She remembered flipping him over with more strength than she ever felt previously and unleashing her final splashes of pleasure on the boy's exposed penis and balls. The euphoria of splattering her intern's genitals was so intense that it practically rewired Bonnie's brain. It had been a mystery then, but now it made more sense.

"I'm a male host... I carry the infection... and I passed it on."

"Oogh mmmmm!" Jack moaned enthusiastically.

The intern's tongue wiggled up the underside of Bonnie's worm, finally sending her over the edge. The tingle started in Bonnie's heavy balls and then rocketed up the length of the parasite. At that moment, the female part of Bonnie disappeared entirely. She was a horny, uncontrollable man and she needed to bust in her slut's mouth. She buried her length down Jack's throat and sobbed as she came, pumping load after load of manly seed deep into his gullet.

As Bonnie finished, the gnawing hunger flooded back into her. Her new testicles tingled like two big reactors, pumping out potent hormones. Intense chemical signals screaming at her body to grow and transform. She had a new biological purpose, one that terrified and baffled her, and her current body was simply not up to the task. She was still so weak and small. A man was supposed to be large and dominant. Bonnie imagined what she was soon to become and the mental images frightened her, but the transformation seemed inevitable. Her very genetic essence was changed for this purpose.

"Are you okay, Bonnie?"

Jack looked up at her with big blue eyes that seemed to glitter. His cheeks were rosy and his lips looked plump and red. He seemed softer than ever, which was saying something, because he had never been particularly masculine. Part of Bonnie wanted to take him for a third time, but the hunger was stronger. She knew that each new meal would bring her closer to a hulking, hunky body that felt alien and scary, but she couldn't fight the urges.

Bonnie kissed her intern on the lips and pulled him towards the door. What she did to Jack that night was wrong on so many levels, but now the boy was the only person she could share this terrible journey with. Sex had bonded them permanently.

"I'm hungry, darling. Let's eat."

2 - Through the Looking Glass

Brynn cried out all her tears after about an hour. After that, she just felt empty.

A stranger looked back at Brynn from the full length mirror of the guest room. To Brynn, her new reflection still looked like it came from a funhouse. She was used to straight lines and subtle curves. Her face was supposed to be sharp and angular, not soft and supple, with plump lips and blushing cheeks. Her swelling cleavage and bulging bottom looked ridiculous and clumsy to her.

Apparently, these were the features guys loved, but Brynn had her doubts. They didn't do her any good. Claire was older and pudgier, and still managed to claim Alex without trouble.

The guest room shared a wall with the master bedroom. Every now and then, Brynn heard a bump or rustle. Each little sound sickened her, because she knew what those sounds meant.

"Why did she have to take him from me? It's not fair."

Brynn's phone buzzed. It was an alarm reminding her to take her meds. She glanced at the pill bottle, and then back at her reflection. While the parasite radically transformed Brynn's body, the antiparasitics came with their own changes. The girl in the reflection was paler than usual, and there were dark circles under her eyes. Her enlarged breasts sagged slightly, and there was bloating around her belly.

The drugs had other side effects as well. They gave Brynn horrible, stinky gas. Of course Alex wouldn't fall for her. The medication turned her into a depressed, flatulent whale. It blunted all of the beneficial changes the parasite brought. Claire insisted on Brynn taking the medication, and at the time it seemed like genuine sisterly concern. Now Brynn was seeing her sister's actions in another light.

She was jealous and wanted to keep him for herself.

The alarm kept ringing and ringing and ringing, but Brynn did nothing. Finally, she picked the bottle up, opened it, and gave it a shake. About half the pills remained. The doctors warned her at the hospital that she needed to complete the full round of antiparasitics or there was a high chance that the infection could bounce back. Was that really so bad? The infection made Brynn feel sexy and beautiful. The medication just made her feel flat.

If the infection comes back, maybe he'll fall for me instead...

Brynn wasn't a dumb girl. She knew it was crazy to think that Claire sabotaged her new body with the medication. Even so, the thought kept gnawing at her. Whether it had been intentional or not, the end result was that Brynn got cast to the side while Claire rekindled her love.

"I should take the medicine. It is the logical thing to do."

Brynn overturned the bottle into the trashcan. The bottle felt lighter afterwards, and so did she. In some cases, the cure was worse than the poison. The infection never hurt her. In fact, it made her feel incredible. Excitement sparked in her chest as she anticipated its return.

What followed was a restless night of little sleep. Around two in the morning, Brynn awoke covered in sweat, feeling exuberant. Her chest itched like made, just under the skin, and her clit burned like a hot iron. For the first time in a while, she felt horny - really horny.

The infection was back, and with it came the new Brynn. This Brynn wasn't going to let Alex slip through the cracks.

3 - Feast of Shame

They hit five fast food restaurants and a grocery store on their way back to Bonnie's townhouse. While Bonnie walked through the aisles of the store, desperately trying to hide the new bulge between her legs, Jack clung to her like a doting girlfriend. It was more than a little embarrassing, and it certainly drew puzzled glances. As much as Bonnie wanted to tell him to give her space, Rex felt differently. Before she could open her mouth, the worm hit her with a jolt of pain. It now recognized Jack as a 'female' mate and greatly enjoyed the intern's proximity. The longer they walked, the more blood trickled into the worm, engorging it to a mortifying degree.

When it was all said and done, Bonnie spent nearly two hundred and fifty dollars on food for that evening, and it still seemed like too little. She descended on the heap of fried chicken, french fries, burgers, and junk food like a ravenous animal, stuffing her gullet as fast as she could. Very quickly, normal hunger abated, but the worm pushed her past regular limits using its nasty conditioning.

Please stop. I don't want this. I don't want to change!

The worm seemed to respond to Bonnie's silent pleas with the cold dismissiveness of nature itself: silent impulses. Her conscious brain crumbled in the face of primordial instincts.

Jack gorged himself as well, which Bonnie took as further proof the boy was now infected. The question was, which type of infection would he succumb to? He didn't exactly seem to be surging with testosterone. In fact, it was quite the opposite. He seemed softer and sweeter than ever, with blushing cheeks and bright eyes. If Bonnie hadn't been overwhelmed with hunger, surely she would have taken him where he sat.

The phone call came just as Bonnie demolished a half rack of ribs. She was at one of the lowest points in her life, covered in grease and sauce while feeling a twitching monstrosity surge between her legs. Her phone said the caller was Alex, but when Bonnie finally answered, it was Claire who spoke.

"Bonnie, it's me, Claire. Are you okay? Are you safe?"

Hearing her best friend's voice sent a rush of fresh blood into the parasitic phallus. The mental image of Claire's brilliant red hair and swelling bosom was almost too much to comprehend. It forced Bonnie to think of her friend in a way that felt profoundly wrong.

Bonnie stared at her throbbing, parasitic erection, and at the masculine swells underneath it. She was certainly not okay, but Rex wasn't going to let her say that. The conditioning pain arrived before Bonnie even opened her mouth.

"I'm fine."

"Thank God. Listen, we had a run-in with some of the infected interns today. We're okay, but I think I accidentally endangered you in the process. They took my phone, and they know about the work you're doing in the lab. How close are you to finishing your report? If you're close, just stay home and avoid the lab."

Bonnie wasn't close to finishing the report, not that it really mattered. Rex wouldn't let her tattle on the infection anyway. As for the horny, infected interns, she wasn't concerned in the slightest.

Those guys are going to be in for a big disappointment if they come after me. For all intents and purposes, I'm one of them.

That thought made Bonnie want to scream. Her gender dysphoria was getting really bad. Each twitch of the worm, every dirty, unwanted thought, every gulp of food. It all brought her closer to a fate that horrified and disgusted her. She didn't want to be a stranger in her own body. She was a woman, damnit! She wanted to stay a woman.

"I'll stay home for a few days, don't worry."

"Good. Stay safe! Out of curiosity, how are things coming?"

"They're fine."

"Have you discovered anything interesting?"

"I really have to go, Claire. I'll talk to you later?"

"Oh, okay..."

Bonnie hung up, unable to bear the conversation any longer. She had known Claire for a decade and was used to the sound of the woman's voice, but now she heard it with entirely different ears. She heard the soft, sweet voice of a fertile female. So soft, and plump, and breedable...

"No! Enough with these gross thoughts!" Bonnie sobbed.

Rex was right there to punish Bonnie for challenging her new masculinity. The pain was overwhelming, but so was the dysphoria. Bonnie never felt as much sympathy for trans people as she did at that moment. She was essentially one of them now. Her brain told her she was a woman. It expected a vagina between her legs, not these horrible, manly swells. Her femininity had become sisyphean, constantly struggling uphill against the overwhelming weight of male hormones and instincts.

Rex's conditioning and Bonnie's dysphoria duked it out until base instincts took over. Bonnie was desperately hungry, despite having eaten thousands of calories already. Her belly bulged as if she were a few months pregnant (the only semblance of childbearing she would ever experience now). She dragged a supermarket cheesecake over and immediately dove in, gobbling down two slices in less than a minute. The pain of her esophagus stretching was immense, but the hunger pushed her past her normal limits. Quietly, Bonnie began to cry.

Jack noticed and moved in to comfort her. He looked so soft and delicate. Bonnie wondered what her infectious semen had done to him, and how such a transformation would progress. Jack plucked up a slice of chocolate cheesecake from the variety pack and snuggled in next to Bonnie.

It was a night of conflicting emotions. On one hand, Bonnie wanted to scream at Jack to get off of her. He was so damn touchy and Bonnie already wanted to crawl out of her own skin. On the other hand, it felt so comforting to be wanted by someone. The infection twisted her body to be as unappealing as possible. Heterosexual men would be disgusted by her male genitalia, while gay men would find her too feminine. Ditto with women (not that she had any interest in women, yuck.)

Rex punished that thought immediately. Bonnie felt sharp pain, followed by an influx of images of pretty women she knew. Claire was featured heavily in this montage, but there were other women as well. Brynn was another, particularly inappropriate imagining. Why did Claire's young sister have to be so damn bodacious?

"What's wrong? Are you hurt?"

In fact, Bonnie's body hurt like hell. Her bones ached and she felt feverish.

"Why are you being nice to me, Jack? What I did to you was horrible! I'm so sorry."

Guilt was a new vector of suffering for Bonnie. Now that she had time to sit with what she did, she was horrified. She had raped the poor boy. She fully expected him to rush to the police afterwards. Instead, he was clinging to her like an infatuated lover.

"It was frightening at first, but I'm glad it happened."

"You're glad?!"

Jack blushed furiously, causing him to look unbelievably pretty and feminine. The sight twisted Bonnie's brain as the worm's desires and her own repulsions fought each other.

"Can I let you in on a little secret?"

Bonnie nodded apprehensive. She already felt way too close to her intern, but she couldn't imagine that any revelation could cause her more trouble than the infection already had.

"I like you. I've liked you since I first met you."

"I thought you liked guys more than girls."

"That's true. I'm really not very sexual, and boys are the only thing that really get me going in that respect, which sucks because most boys are awful. You see, that was the bind I was in for so long. My heart fell for you. You were so sweet and loving and accepting right from the get go. You challenged me, while still making me feel welcome. Unfortunately, my body wasn't attracted to you... until."

Jack gently caressed the worm between Bonnie's legs, sending bolts of sexual lightning into her brain.

"Stop it!"

Jack looked like he had been smacked.

"You... don't want me?"

"I don't want any of this, Jack! I don't want to be a man. I don't want some parasitic worm growing off my crotch like a mutant penis, and I certainly don't want balls."

"But you wanted me earlier..."

"Jack, there's something very wrong with me. I shouldn't have done what I did to you. I'm so sorry. I care about you, I really do, but we can't be together. I'm your boss, I raped you, I'm ashamed and horrified by my own body. There are so many reasons why this will never work!"

Jack's big blue eyes filled with tears, "Does this mean we can't be together?"

"I'm sorry Jack. I'm so sorry. First thing tomorrow, I'm forcing myself to the hospital to see if this horrible change can be reversed. I suggest you come too. This thing has grown way beyond what either of us can handle."

Bonnie didn't really think she could resist Rex's conditioning enough to drag herself to the hospital, but maybe Jack could get checked out. She hated how much she was hurting him, but it was for his own good.

"Okay," Jack whimpered. "Can I at least sleep here tonight? I don't feel safe walking home after dark."

"Of course."

Jack picked himself up and moped to the bedroom without another word, leaving Bonnie feeling as if she had kicked a puppy. It was one more misery to add to the pile. She sat with her shame, feeling the parasite's corruption slowly encroaching on her sense of self. She wanted to cry, or maybe vomit. Unfortunately, the hunger was stronger than ever.

"I don't want this," Bonnie sobbed. "I don't want to be a man. I don't want to dominate or hurt anyone. Please, make it stop!"

There was something so horrifying about the dysphoria crashing over her. There was no comfortable place to retreat to. Her own body was becoming alien to her.

What followed was a doom spiral in which Bonnie crashed out over her changing body, stuffed her face to ease the pain, then remembered what the food was doing to her. This triggered a new wave of dysphoria, horror, and shame. Hours passed as Bonnie gobbled up more and more of the wretched feast. Around midnight, the bottom finally fell out from under her.

A severe fever, paired with nasty chills and aches, washed over the woman. Her vision blurred and her world tumbled. The dysphoria was worse than ever, but her conscious thoughts died away, leaving her with nothing but an overwhelming sense of wrongness.

"I'm a woman! I don't want to be a man. Oh God, please make it stop. Please..."

Bonnie collapsed on the couch and lost consciousness. With her body flush with fresh calories, the real transformation was ready to begin. Her female mind struggled to hold on while a beast gestated under the surface.

"I don't want to be a man... I don't want to be man... I don't..."

4 - A New Target

Shawn was still stewing over Brynn. He kept chasing pretty girls only to have his heartbroken. Now he felt more alone than ever, despite having the body and charisma he always dreamed of possessing. It felt like a cruel joke.

"Damn, I can't wait to fuck a scientist! She's hot too!" Ravi gushed over the image on Claire's phone.

Shawn had to admit, the woman looked fine as hell. She was the perfect mix of nerdy, professional, and beautiful. Her face was so round and feminine, with full lips and big brown eyes. Her figure was something to look at as well. If that was what the woman looked like before infection, Shawn wondered how she would look after.

There would need to be a tempering of expectations here. Shawn knew nothing about this chick beyond where she worked. A pretty face was fine, but he found himself craving more.

Face it, you still want Brynn.

Bonnie Huntsman was really just a consolation prize. A pretty face to fuck and corrupt in order to get back at that bitch Claire for taking her sister away from him.

There was a practical angle to their plan as well. Apparently, this scientist chick was trying to figure out the infection. Shawn didn't like that. He didn't want to be cured. If anything, he wanted the parasite to infect him further, making him bigger and stronger. They were going to scuttle any and all research and pull Huntsman into their orbit. From there, Shawn planned on using her to get to Claire and Brynn. If all went well, he would have a whole harem of beautiful women at his disposal.

"Dude, I can't wait. When do we strike?"

"Calm down, Ravi. We need to make sure we're ready. We go in tomorrow at 1pm."

"Ugh, fuck I can't wait."

Shawn glanced at the image of the beautiful woman. He still yearned for Brynn, but he had to admit that this Bonnie chick was growing on him. Something about banging a beautiful, mature woman drove him nuts.

"Get ready, lady. You and I are about to get very well acquainted..."

5 - The Beast in the Garden

Bonnie awoke in a soft, warm meadow filled with wildflowers. An ornate fence enclosed the area, and along the border there were trees bearing plump, ripe fruit. The air was sweet and soft, with a gentle breeze.

Everything felt right.

Bonnie glanced down at her body and saw that she was naked. At first, this startled her, but her shame quickly died away. Instead, she felt a gush of relief. Her body was back to the way it was supposed to be. There was no obscene, phallic worm jutting from between her legs. Just a proper vagina topped with a manicured bush.

Bonnie relaxed as she realized everything was back to normal. This was exactly how her body was supposed to feel. Had everything prior been a nightmare? If so, what was this place?

Bonnie drank in the flowers and swelling fruit. All the colors and softness. It felt so womanly and nurturing. This place was paradise.

Then came the noise.

It sounded like thunder, or the trampling of a giant. The ground began to shake. Bonnie looked off in the distance and saw the trees swaying as if pushed by a massive body. As she watched, she felt a deep sense of dread.

"No, stay back!"

The beast did not listen. It emerged from the tree line and trampled the ornate fence with a massive foot. It was a monstrous amalgamation of every man that ever wronged Bonnie. Every shitty boyfriend, bullying jock, and dismissive boss. It was a hulking figure with a body rippling with unnatural muscle. Between its legs swung a manhood like a tree trunk. Even from a distance, Bonnie could smell its musk.

As soon as the beast saw Bonnie, it charged, letting out a deep, manly war cry as it did so. Bonnie immediately turned to run, but she was hopeless. The beast was twice her height, running on legs pumped full of superhuman muscle.

"Stay away!" Bonnie begged. "I don't want this. I don't want you."

The beast morphed into so many men from Bonnie's life. Briefly, it took on the balding head and square jaw of her father. Then it transformed into the janitor that bullied her in the middle of the night a few days prior. It became the cop that gave Bonnie her first (and only) speeding ticket, then the jock that sexually harassed her during her freshman year of college. Its shape was ever changing, but its masculine core remained. Its raw, muscular power radiated from it as if it were a nuclear reactor.

As the beast stepped into the garden, its corruption began to spread. Flowers wilted and fruit rotted while vines and branches thickened. Veiny mushrooms surged out of the ground, filling the air with musky, bleachy scents that made Bonnie want to gag.

When the beast caught up to Bonnie, it kicked her right in the back, knocking the wind out of her lungs and sending her flying several feet. She landed in a ruined heap among the tainted mushrooms and vines.

Bonnie fully expected the beast to rape her, but what came next was far worse. She felt the heat of the monstrosity as it mounted on top of her. Two gigantic, obscenely muscled arms framed either side of her. Those muscles were as much a signifier of masculine power as a dick and balls. No woman could possibly achieve such an unholy physique.

Two beefy hands pressed into Bonnie's shoulders until the skin and muscle split apart. The pain came paired with a keening, wailing sound that Bonnie eventually realized was her own voice screaming. The beast's hulking arms surged down into Bonnie's own pair, causing hers to swell and grow as their flesh combined. Paired with the immense pain was a sudden sense of immense power. Bonnie watched in horror as her biceps and triceps, forearms and shoulders expanded in ugly, ragged pulses until they were indistinguishable from those of the beast. Big, burly, masculine arms built for power and domination.

With their arms bonded, the beast proceeded to press his chest into Bonnie's back. Once more, the flesh split and then fused, merging woman and beast into one. Bonnie's back and pecs stretched and filled in successive pulsations. She looked down and watched as her growing pectoral muscles consumed her breasts, leaving her with the broad, glistening chest of a male bodybuilder. She felt the itch as fine black hairs sprouted on the surface. Her screams suddenly became louder and more resonant as her lungs doubled in size.

Next, the beast thrust his hips. On one hand, this was the moment Bonnie dreaded the most, and yet it was also the least surprising. She had already undergone all of this once already in real life. She felt the dirty, perverted little itch spark in her clit as the beast's monstrous cock disappeared into her plump, womanly ass. A moment later, her girly nub stretched into a thick, meaty cock of her own. Her pussy tightened and shrank as heavy balls took its place. With the testicles came the surge of the testosterone, paired with a deep sense of loss. Bonnie was soon to be cast out of the sisterhood of womankind forever, forced into the wild and wicked forest of man.

Next came the legs, acting much like the arms. Bonnie's thighs thickened and her calves bulged. She grew over a foot taller, and became even more closely bonded with the beast. By now, only their heads were separate. She could feel his terrible masculine power infecting and corrupting her. Her skin itched as hair sprouted in places it had no business being on a woman. Her new male appendage twitched and dribbled precum. The last vestige of her womanhood was her head and the voice it produced.

The beast let out a deep, throaty war cry as he began the final fusion. Bonnie felt the thing's rough, angular face press into the back of her head. Evil thoughts surged into the woman's mind as the bones of her soft face grew and transformed to give her sharp, angular features. Her vocal chords swelled, deepening her voice as her body erupted with debauched, unholy pleasure.

The last embers of Bonnie Huntsman's womanhood died out as the beast took control.

***

Jack stirred as he heard the door open. His whole body ached and itched, especially his chest, which felt painfully swollen. His cock felt somehow smaller, but it tingled like a little bottle of electricity, threatening to drive him mad.

As Jack listened to the footsteps enter the bedroom, fresh hope kindled in his heart.

"Did you change your mind?" He cooed.

A tall, imposing shadow stood at the foot of the bed. It was impossible to make out any features in the darkness, but Jack could tell from the silhouette that this guy, whoever he was, was big and well muscled. He suddenly froze with terror.

"Who are you?" It was a stupid question to ask, but he couldn't help himself.

Instead of answering, the figure leaped onto the bed, causing the entire room to shake. A musky, lusty smell filled Jack's nose as the guy crawled on top of him and pinned him to the bed.

"Get off of me!"

This freak had clearly broken into the house. Jack wondered what this monster had done to Bonnie. The thought made him sick to his stomach.

With terrifying strength, the attacker forced Jack's legs apart and lifted his ass into the air. The fat, fleshy glans of monstrous cock slid between Jack's cheeks.

"Wait a minute... stop! You're too big."

With a deep, defiant roar, the stranger thrust his hips and buried himself to the hilt, causing Jack's entire world to go fuzzy from the pain.

The stranger pressed up against Jack. His body was very muscular and sweaty, filling Jack with unwanted lust. There was, however, something odd about the man's upper torso. Something squishy, soft, and fleshy seemed to separate the two of them - two somethings. Two large, swelling mounds of flesh. If Jack hadn't felt the dude shove his cock into his ass, he would have guessed those mounds were the stranger's breasts.

Then Jack heard a voice he recognized. It was deeper than before, now resembling that of a teenage boy whose voice had just started to change.

"Isn't this what you wanted?" Bonnie grumbled. "So take it!"

Jack screamed in delicious surrender.

6 - Brynn 3.0

As soon as Brynn woke up, she knew something was different. She felt amazing.

As she stretched, she noticed the way her nightshirt stretched over her bulging chest. Her breasts, already so much bigger than they had been before this strange vacation began, now felt even larger. Not only had they seemingly grown another cup size, but they felt springier than ever. They moved in tight, sudden jiggles with every shift and sway of Brynn's body.

It wasn't just Brynn's tits. A look in the mirror confirmed that everything had been enhanced. Her pale ass was fatter and rounder than ever, while her midsection was not merely slim, but supple and toned. Her face looked sharper and more striking, with brighter eyes and lips curved into a permanent sultry pout. Brynn recognized every bitchy, arrogant hot girl and queen bee she ever met in that reflected face, and she relished joining their ranks.

From the main room, Brynn could hear giggles and chatter along with the clatter of plates. Brynn winced, but her pain was fleeting. Over the course of the night, her heartbreak matured and grew thorns.

So the former lovers had a little reunion, eh? They better enjoy it while it lasts.

Suddenly, the door to the guest room opened and Claire peaked in. When she saw Brynn's naked body, blood rushed to her face.

"Jeez, Brynn! Put on clothes."

Brynn simply stared at her sister while jutting her chest out so that the woman got a perfect view of her superior body. The infection was back and stronger than ever, and as such, all love and connection with Claire was stripped to the bone. All Brynn saw was a rival female from outside the tribe. Competition that needed to be crushed.

"Or not," Claire reluctantly continued. "Alex and I are going to the police station to give our testimony. After that, I'm going to try and pin Bonnie down. We really need her report if we want the authorities to take this thing seriously."

Brynn perked up.

"Is Alex going with you? For Bonnie, that is," It didn't sound like it.

Claire shook her head, "Nah, I told him to come back here and keep you company. Hopefully the old geezer won't bore you too much."

Claire didn't see the fire in Brynn's eyes. If she had, things might have turned out differently.

"No, not at all," Brynn said, her soft, kissable lips curving into a naughty little smile.

"Great, I hope you guys have fun."

Claire tottered off, leaving Brynn to vibrate in place with anticipation. The past week had been a roller coaster and last night had been the worst drop of all, but now she was on the rise. This was her chance.

7 - A New Kind of Man

Bonnie Winnifred Huntsman had spent the last thirty one years of her life as a woman, yet every new thrust into Jack Teagarden's tight, bubbly ass made her forget this truth more and more. Her body moved to the command of ancient, animalistic instincts transplanted into her mind by the parasite, and god what a body it was.

The dysphoria wasn't gone when Bonnie awoke from her dream. If anything, it was stronger than ever. That disjoint between the truth she always knew and the reality her body and mind now conformed to was nearly insurmountable. Instead, the parasite played a little trick on the psyche of the newly transformed male. Whereas before the dysphoria caused Bonnie misery, it now filled her with dirty, disgusting sexual glee.

Every agonizing swell of muscle, every bulge and ripple sent blood pulsing into Bonnie's worm. The parasite was a sculptor, carving an adonis out of the former woman. It felt so raw and wrong to grow and transform, and that wrongness was euphoric.

It wasn't just Bonnie's body, but what she was doing with it. As a woman, domination never appealed to her. Now that she had switched teams, she felt differently. There was something about pinning skinny little Jack to the bed and filling him to the brim that lit up every neuron in her brain. With each powerful thrust, Bonnie felt her worm-cock bury to the hilt while her fat testicles slapped against the intern's plumping ass.

It helped that as Bonnie transitioned into a proper male, Jack seemed to be moving in the opposite direction. In the darkness of the bedroom, Bonnie couldn't make out much, but she could feel a whole lot. Jack felt softer and yummier than ever in Bonnie's big, meaty hands. Even the boy's scent had changed, becoming sweeter as the night wore on.

"Please, Bonnie, I need a break," Jack squeaked and Bonnie went in for another round of rutting and thrusting.

"We're done when I say we're done!"

Good God, that voice! Just hearing it caused Bonnie to feel her throat to confirm the slight bulge. The voice was deeper, yet also unmistakably Bonnie's.

True to her word, Bonnie thrust herself on her frail little mate for several minutes until the mind shattering orgasm washed over her. Her body seized up, her balls puckered, and jet after jet of hot, sticky boy batter splattered into Jack's anus.

Jack collapsed into a twitching puddle. Meanwhile, Bonnie found her first moment of clarity in hours. The world spun around her.

What have I become?

Bonnie pulled the worm out of Jack's asshole and stumbled to the bathroom. The mirror revealed a startling truth.

The person in the mirror was very tall, standing well over six feet. The physique was absurd. The amount of muscle grown in a single night baffled Bonnie. There was no biological precedent for it. Bonnie's upper body in particular was monstrously endowed, with gigantic, rippling biceps and bulging shoulders. Bonnie's neck fused into the shoulders to form a muscular triangle. It was the kind of musculature male bodybuilders spent decades perfecting through the use of training and drugs. Somehow, Bonnie gained an even grander version of that physique in a single night through a parasitic infection and a gut busting feast.

As Bonnie looked closer, she noticed other things that bewildered her just as much. Her face, once blessed with feminine softness, was now sharp and striking. She looked more handsome than beautiful, although a blush of womanly appeal still remained. Her lips remained plump and soft, and her eyes still looked bright and big. The features of her face were too sharp to be those of a woman, but too delicate to be those of a man. To cap it off, there wasn't a trace of facial hair.

The more Bonnie looked at her body, the more perplexing it was. She fully expected for her breasts to be gone, replaced with big, hairy pecs, but instead they seemed larger than ever. They actually suited Bonnie's broad, muscular chest quite nicely.

The longer Bonnie stared at herself, the more she was certain of one thing: she was no longer a woman. Every cell of her body cried this truth. She kept brushing her beefy fingers over her massive biceps. No woman had arms like these. The bulging biceps and triceps affirmed Bonnie's new gender nearly as much as her balls and penis.

Her penis.

Rex twitched as if to remind Bonnie it was still a separate organism, although that separation was harder and harder to believe. The seam between Bonnie's skin and the attached worm had disappeared completely. The bond was complete. By now, Rex looked exactly like a very large, very veiny male sex organ. The skin of the worm had even paled to match Bonnie's complexion. For all intents and purposes, Rex was Bonnie's penis.

Beneath Rex dangled Bonnie's new testicles, the organs that defined her as a male of her species. The swells seemed bigger than ever. They ached and pulsated in their scrotum. Several small black hairs had sprouted on the skin of Bonnie's sack overnight, adding to the raw maleness of her body.

"I am a man."

No, that wasn't quite right. Her voice was deeper, but not necessarily manly. It was resonant and powerful, darkened with testosterone, but it didn't quite reach the depth of a normal man's voice. Her body was unbelievably muscular, but also curved in a way that was distinctly feminine. Her broad, muscled chest tightened into a waspish waist blessed with a rippling eight pack. Farther down, her hips flared to ripe buttocks. The combination of womanly curves and manly bulk was disorienting.

Still, she was male. Her vagina, her clit, her ovaries, and her eggs were all gone. She would never bear a child, but there was a good chance she would conceive one. The ramifications of her sex change were starting to sink in. Her relationship with every person she knew was about to change fundamentally - especially with Claire.

"Oh, Claire..."

Bonnie gripped the thick base of her worm cock and gently coaxed it to full mast as she began to think of her busty, beautiful ginger friend. The two women had been a perfect match from the moment they met, with Bonnie's steady, levelheaded cheer tempering Claire's fiery side. Now everything was flipped on its head. Bonnie had only been a male for a single night and she could already sense that her personality had changed radically. With a pair of steroid factories pulsing between her legs, she was developing one hell of a temper - and a libido. The thought of Claire's soft, womanly body did dark things to Bonnie's new male brain.

"I shouldn't be thinking about this," Bonnie huffed in her dark voice.

Luckily, a distraction soon presented itself. Unfortunately, that distraction did nothing to sooth Bonnie's arousal.

"Eek! What's happening to me?!"

The voice was sweet and girly. Bonnie hardly recognized it as Jack. She rushed into the bedroom to find the boy cradling something on his chest. Her eyes adjusted and she realized that what the boy was cradling was his chest.

"You have breasts?"

Jack started when he heard Bonnie's voice. He shrank back towards the corner as she approached.

"Come on, don't be like that. I thought you were into me," Bonnie said as she loomed over him to get a better look. "Am I too much of a man for you now?"

"What? No! It's just... I'm not ready to have sex again."

Bonnie considered disciplining her intern for defying her, but stopped herself.

I might be a freak, but I'm not going to let myself become a bastard.

"Let me see," Bonnie gently brushed Jack's hands away to get a better look. What she saw sent fresh blood into her cock.

To call Jack a boy wasn't really accurate anymore. Just as Bonnie had undergone a freak second puberty over the course of the night and transitioned into a very muscular, very powerful near-man, Jack had blossomed into a very beautiful girl. By some awkward twist of fate, the two of them now belonged to the same strange transitionary sex. They both had breasts and female features, but possessed male genitalia. The only difference was that Jack's cock seemed to be shrinking as Bonnie's continued to swell.

Jack's penis was little more than a two inch nub now. His balls had retreated into his body, leaving a patch of wrinkly skin that seemed ready to split at any second.

Is he becoming female?

It certainly seemed like Jack was changing sex, and there was no clearer evidence than his chest. What was once a flat, bony expanse now featured two plump, perky breasts. Jack boobs were puffy and plump, hovering on the border between modest and large. If Bonnie had to guess, he was probably a C-Cup, but he was likely far from finished growing.

"They're very nice," Bonnie said.

Jack panicked and covered himself once more. As Bonnie looked at him, she noticed all the small changes to his body. Just as her jawline had chiseled and her features sharpened, Jack's had softened. He possessed the face of a girl, and a very pretty one at that. What remained of his boyishness only enhanced his beauty, making him look like a hot tomboy. His freckles and sandy hair were darling.

"I don't want to be a girl, Bonnie!"

Bonnie simply chuckled and stroked Rex affectionately.

"I didn't want to be a boy, but here I am."

"We have to go back to the lab and figure out how to reverse this."

"Reverse what? It's changed our genes, Jack. Look at my body. Look at these muscles! There's no treatment that could change me back, and even if there was, I don't think I would want it."

Jack's eyes widened. He looked so beautiful.

"What are you saying?"

Bonnie caught a glimpse of herself in the full length mirror. Her reflection was undeniably striking. Those surging, superhuman biceps and the beautiful androgyny of it. There were parts of her that could appeal to both sexes, allowing her to spread her infectious new treasure far and wide. Bonnie's body made up for her womanly features with a godlike physique. She was bigger than any man she ever met. She even made professional athletes seem puny by comparison.

Those muscles weren't something Bonnie would ever fully adjust to. Nothing quite affirmed her new maleness quite like her gigantic, burly arms and broad, swelling shoulders. The fact that those muscles materialized in a matter of hours only further bewildered her. It made Bonnie think of He-Man.

I'm a new kind of man, she thought with a chuckle. A She-Man.

The name scratched Bonnie's brain just right. Yes, she was a new kind of male. A new breed that was hotter, bigger, and more attractive than the old variety. She possessed everything attractive about women, paired with the raw power and dominance of a man.

Dysphoria washed over Bonnie now. Her new identity was so gnarly and primal. A small part of her soul still identified with the sweet, attractive woman she used to be and it couldn't wrap itself around this girthy new identity. The disjoint didn't hurt anymore. Rex saw to that. Instead, Bonnie splurted a small load of precum from sheer delight. The pale, translucent goo caught Jack right on his perky chest.

"I'm saying that we should get used to our new bodies. As a first step, let's get some clothes that fit. You're going to need a bra to support those puppies, and I'm going to need shirts that don't rip when I put them on."

"I don't want to be a girl," Jack whimpered defiantly.

Bonnie grabbed him and pinned him to the bed. She looked into his soul and forced him to go limp.

"You don't get a choice."

With that, Bonnie claimed her mate.

8 - The Towel

"Brynn, are you home?"

The dull roar of the shower silenced a moment after Alex spoke. He took a deep breath and braced himself for an awkward afternoon.

Alex got along with Brynn plenty well. She was a sweet, smart girl. She kept up a conversation well enough. There was nothing wrong with her, per se.

There was one thing: her new body. Even before the infection changed Brynn, it still gave Alex whiplash to see the girl all grown up. He remembered a scrawny, timid little girl who would ask the most interesting questions in a near whisper. Now she was a woman! The parasitic infection only exacerbated this fact.

It wasn't like Alex wanted Brynn, especially now that he had rekindled things with Claire. He had no romantic interest in the girl, but he was still a man. He would never try anything with Brynn, but it still felt weird to sit home alone with her.

"Just keep the conversation casual. Talk about animals, or books, or whatever. Remember, she's cool. Just be cool."

There were footsteps in the hallway. Alex looked up in time to catch a sight that nearly gave him a heart attack. Brynn wore nothing but a white towel wrapped around her body. She tied this towel in such a way that her enlarged bosom seemed fit to burst out of the top.

Jesus, did she grow again?!

"Hi, Alex!" Brynn bounced on her feet and waved, causing her chest to billow upwards.

It's gonna be a very long afternoon.

"Uh, Hi Brynn. Sorry, I can go into the other room if you need to change."

"No need, I'm about to grab lunch."

"In that?!"

Brynn simply giggled and skipped over to the kitchen. As she passed by Alex, he caught a whiff of her strawberry shampoo. Mingled with that forward scent was a darker, muskier scent that made his head swim.

"I think I'm going to go hang out in Claire's room for a little bit. Let me know when you're dressed."

Brynn whirled around and fixed Alex with a wild look. All the girl's timidity was gone, replaced with a fire that cut Alex to his core.

"Stay," Brynn commanded.

Against his better judgement, Alex plopped down on one of the stools at the kitchen island. What followed was the hardest moral test he ever faced.

Brynn's towel did a piss poor job of covering either end of her. Whenever she bent over, Alex got a full view of the girl's pale buttocks. After the first time it happened, Alex did his best to anticipate these moments and look away, but sometimes Brynn caught him by surprise. Even worse were the moments when the towel would come loose, forcing Brynn to catch the unfurling knot, which just so happened to be between her breasts. In the process of securing everything, she often came dangerously close to flashing Alex.

Alex fought valiantly, but he was still human, and male. Blood surged downwards. His cock strained against his khakis, leaving a noticeable lump. His erection trapped him, lest he stand up and reveal his bulge to his girlfriend's sister.

"I'm so sorry, Alex. Do you want anything?"

Brynn twirled around as she asked the question. Her breasts caught up to her a beat later.

"No thanks, I'm not hungry."

Alex had never seen someone take so long to make a peanut butter and jelly sandwich before. The process stretched out over the better part of ten minutes as Brynn toasted the bread, then stuck it in the fridge to cool, scooped out peanut butter and whisked it with honey, and microwaved the jelly. The finished product was more appealing than Alex imagined it would be, but it was still baffling.

Brynn was as slow at eating as she was at preparing. Alex wanted to flee, but forced himself to stay. After all, Claire would kill him if he hurt her baby sister. After a few minutes of awkward small talk, they settled into a proper conversation. Brynn was a sweet, quirky girl. Despite transforming into a sex goddess, she still had the brain of a nerd, which made talking to her a lot easier. Before long, Alex managed to ignore the girl's kissable lips and bombshell body and focus on her as a person. He was actually having fun.

During a lull in conversation, Alex suddenly remembered something he always wanted to ask Brynn.

"Do you remember the first time we met? Claire brought me to your house for Thanksgiving our junior year."

Brynn became grave. Her eyes looked like saucers.

"Yes."

Alex suddenly got a new sick feeling in his stomach. This had always been a bit of a sore spot for him. Seeing Brynn's reaction only confirmed his guilt.

"Did I upset you or something? I remember Brynn shoving me out the back door to keep you company. We started talking about animals or something."

"Dingos. We were talking about dingos."

"Right! Dingos. I remember the conversation going really well, but then I think I made some kind of teasing comment. I can't remember what it was."

"You said I looked like a junior librarian."

Brynn looked more intense than ever, only further confirming to Alex that he had royall fucked up all those years ago.

"Wow, you have a mind like a steel trap. Yeah, I said you looked like a junior librarian. I didn't mean for it to be offensive or anything. I was just being silly. You see, I yap. I just say whatever comes to mind, and I'm way too flirty for my own good. I flirt with everyone. Old ladies, supermarket cashiers, telemarketers. Claire used to fume over it. I don't mean anything by it. It's just how I act. After I made that comment, I remember you getting super quiet, and you wouldn't make eye contact with me for the rest of the night, and clearly I hurt your feelings. I guess what I'm trying to say is that I'm sorry."

Brynn trembled slightly and looked on the verge of tears. When she answered, her voice was a shaky whisper.

"Is that your interpretation of what happened?"

Alex nodded, "I can't think of any other interpretation."

Brynn stood up and faced him. Her scent was stronger than ever. So sweet and buttery. Fresh blood flooded Alex's cock as he breathed it in.

"Middle school was a very bad time for me. I ping ponged between being bullied and ignored. Boys, especially, were cruel. They called me four eyes and stick, freak and loser. They liked to blow spitballs in my hair and spray me at the water fountain."

Alex felt like a big pile of shit. By accident, he managed to shatter what little remained of middle school Brynn's self esteem. Sometimes he hated himself.

"I'm so sorry. I really didn't mean to-"

"Shush!" Brynn placed her finger on his lips, sending an electric tingle through him. "I'm not finished. Up until that night, whenever a boy teased me or made comments about me, it was to hurt me. You did something different. Something that left a much longer lasting mark."

Oh fuck.

"I'm so sorry."

"You didn't hurt me that night. You showed me that a boy could tease me in a fun way. In a way that let me be in on the joke. For the first time, a boy actually showed interest in what I had to say. His jokes were cute and teasing without being cruel. You were so sweet and funny and wonderful."

"Then why did you run away and refuse to talk to me?"

Brynn's eyes felt like two laser beams.

"For the same reason I'm going to do this..."

Suddenly, Brynn opened the towel and let it fall to the floor, revealing the full glory of her body. She possessed a level of beauty that Alex's brain couldn't quite compute. Her breasts were not only massive, but shaped in a way that seemed to defy the imperfection of nature. Her figure tapered to waspish waste with a taut belly, before blossoming into the wide, womanly hips of a fertility goddess.

"I don't understand," Alex backed away slowly, finally realizing the danger of the situation.

"You were the first boy to show me true kindness. The first one to make my heart flutter. I've been carrying my desires like a burden ever since."

"Brynn, this cannot happen. I didn't want to tell you this way, but your sister and I-"

Brynn slapped Alex, and it stung way worse than he expected. How could such slender arms muster so much force?

"I know all about you two. How stupid do you think I am? Do you think I'm deaf?!"

"I'm sorry, Brynn, I really am. I'm sorry I can't reciprocate your feelings, and I'm sorry I accidentally strung you along, but we cannot do this. Do you understand?"

Brynn looked crestfallen, but she nodded. There were tears in her eyes.

Aw hell...

"Okay, fine. Can you please just pick up my towel for me? I don't want to bend over like this."

It was the least Alex could do, and he thought nothing of it. It would be his undoing. As soon as he bent over, Brynn grabbed the back of his head and forced his face into her moist crotch. The whole ordeal only lasted a second, but in that time, Alex's lips slid along Brynn's labia while his nose got a full dose of her scent. Had Brynn been a normal woman, this would have meant nothing but momentary discomfort, but she was far from a normal woman at this point.

Alex shoved the girl away and choked and coughed, trying to spit out her pussy juice, but he was already feeling the effects of her nectar. His head swam and his erection stiffened.

"What the fuck, Brynn?"

Instead of answering, she pounced on him. He tried to get a grip on the girl to throw her off, but she fought like a hellcat. While Alex fumbled for a grip, Brynn found her target almost immediately. Her delicate hand slipped down the waistband of his pants and curled around his erect cock. As soon as this happened, Alex froze in place. He was a good man, but he had his limits. The hottest woman on the planet grabbing his dick was one of those limits. Sensing victory close at hand, Brynn secured her kill, guiding Alex's hand to her breast before kissing him on the lips.

From that point on, Alex belonged to Brynn.

9 - The Clerk and the Cup Size

I don't need a bra!

Those were the words on Jack's tongue as Bonnie hauled him in front of the department store clerk. Bonnie took action before he was able to say them.

"She needs to get fitted for a bra."

"Um, sure thing. Have you grown recently?" The clerk asked Jack.

The clerk was a cute blonde thing. Perky and bright, but dorky enough to be somewhat approachable. At the very least, she didn't seem very judgmental.

Jack nodded without a word.

"You aren't the only one. There must be something in the water. Come back with me and I'll take your measurements."

Jack spared one more resentful glance back at Bonnie. The hulking she-beast was dressed in an oversized rainjacket. It looked ridiculous, but the garment was the only one that could contain Bonnie's new muscles.

After the previous night, Jack had decided something. He still loved Bonnie. Of this, he was certain. He just wasn't sure if he liked her. The infection had forced frightening changes on her body. He thought he would enjoy her becoming male. The fact that they were now so sexually compatible seemed like a dream come true, but Bonnie's new manhood came with aggression and dominance. She made him feel so weak.

The clerk made small talk while guiding Jack back to the fitting room. After closing the door, she requested for Jack to remove his shirt. He hesitated for a good while. His new breasts were mortifying. He didn't want to show them to anyone, even Bonnie.

Even so, Bonnie was right. The more Jack carried these cursed mammaries around, the more they hurt. He desperately needed support.

"Oh wow, I didn't expect you to be braless," the clerk blushed.

"Sorry, I've never needed one before."

The puzzled look the girl gave him would have been funny had it not been so embarrassing.

"What size were they before?"

"They weren't any size!"

"How old are you?"

"Nineteen..."

"Um... okay. Let me get the tape measure and see where you're at."

"My, um, partner thinks I'm a C."

The clerk muttered to herself for about a minute as she figured out the measurements and then finally nodded her head.

"Yup, you're a size 36C. When did you start growing?"

"Yesterday."

"Jesus. Okay, do you feel like you're still growing?"

Jack shrugged. How the hell was he supposed to know? He wasn't exactly experienced with boob growth feelings.

"Do you feel any itchiness or tightness inside your breasts?"

"Yes to both of those. It's so fucking annoying."

"Then you're probably still growing. I can grab you some 36C bras to try on, but you probably want to get a few in larger sizes for when you get bigger."

When you get bigger. It was an inevitability. This was happening whether Jack liked it or not. He had never exactly been the world's most masculine guy, but there was something humiliating about having his manhood stripped from him against his will. Fate could have at least asked permission.

"Okay," he moped.

The clerk disappeared, leaving Jack alone with his new breasts. As much of a shame as they were for him, he couldn't stop looking at them. He swore they felt bigger now than they had when he left Bonnie's house. They seemed to stare at him from his reflection in the mirror like two pale eyes with pink pupils.

"Why do they have to be so big?"

Jack's voice didn't sound right to him. It seemed too soft and high, like someone was filtering him through a voice pitching software.

Carefully, Jack cupped his nascent breasts and sighed. As unwanted as they were, they were oddly satisfying to touch. They felt so full and ripe. Each one took up his entire palm and then some.

"Are they really going to get bigger? They feel huge now."

Jack's bosom was rapidly entering centerfold territory. He initially wondered if the clerk clocked that he wasn't a girl, but now that he got a better look (and feel) at his new tits, he highly doubted it. His rack on its own fully reoriented his figure to a new, womanly shape, and that wasn't even getting into the other changes.

The clerk called Jack pretty, and she wasn't wrong. Jack's face had always been delicate and effeminate, but now it was undeniably feminine. The person in the mirror looked like she could have been Jack's hot older sister.

"How am I going to live this down? Dad's going to kill me..."

The door to the changing room opened and the clerk bustled in with a full stack of different bras, some smaller, some larger. The clerk gave a lowdown on each garment and then pulled out one for Jack to try on.

"I know it's a little frilly, but I think it would look so cute on you."

Jack held the pink lace bra as if it were a dead fish. He really didn't want to wear it, but the poor clerk seemed so earnest, and he was nothing if not a people pleaser. Finally, he slipped it around his chest. To his surprise, it felt cozier than he expected, and the extra support was nice.

"Wow, you look amazing!"

The girl in the mirror was exceptionally beautiful. Her breasts were full and perky, formed into a sumptuous dollop of cleavage by the bra. The pink floral design imbued Jack with a girly, delicate quality that softened his features further. For a brief moment, Jack panicked at his new appearance, then he stopped himself.

The boy that always used to look back at him in the mirror was pale, lank, and unappealing. No girl or boy had ever wanted the person he used to see in the mirror. For as long as Jack could remember, he never really liked himself. Perhaps this was a chance to start over and take on a new identity. This new girl was beautiful and blonde, with a cute face and a curvy figure. She had a big, hunky girl/boyfriend and a body that made cute store clerks coo and gasp.

"Thanks," Jack smiled. "I think I like it."

"I'm Celia, by the way," the clerk shook Jack's hand.

"I'm Jack-Jackie. Jackie Teagarden."

"Aww, that name is adorable. I love it."

Celia's infectious sweetness was starting to get to Jack. Despite his cynicism, he was starting to buy into her compliments and support. She was a real sweetheart. Perhaps she could be a friend...

There was a knock at the door. Celia called out that it was occupied, but the knocking kept coming, growing louder and louder. Finally, the clerk marched over to give the knocker a piece of her mind. As soon as she unlatched the door, it burst open under the weight of a hulking figure. A hulking figure grabbed Celia and muffled her scream.

"Bonnie, what are you doing?!" Jack squeaked.

"I can't take it anymore. This is taking forever, and I'm so goddamn horny!"

Bonnie spun Celia around and pinned her to the side of the dressing room. The clerk's pants were down around her ankles in the blink of an eye. In the next, Bonnie's thick, veiny worm cock emerged.

"If you're so horny, have sex with me and leave her alone!"

"Don't worry, I'll do that soon enough," Bonnie grumbled.

Bonnie had described herself as a "she-man" on the car ride over, and the truth of that identity was painfully apparent at that moment. Bonnie's male desires possessed her like a demon, driving her to do the unthinkable.

"I can smell her pussy. I'm about to fuck a woman. Holy shit, I'm about to fuck a woman with my cock and get her pregna-ugh!"

Bonnie lost control and thrust herself into poor Celia. There was a wet tearing sound, followed by the poor clerk's muffled screams. Then Bonnie's deep, lusty grunts drowned everything out.

Jack watched in horror. The woman he fell in love with had transformed into a monster. That blasted worm between her legs had turned her into as much of an awful meathead as any on Jack's college campus, and things weren't getting any better.

Finally, Jack did what he had always done when things went sideways. He wasn't proud of it, but he didn't see any other solution. Bonnie was now one of the strongest people alive and locked in a kind of breeding rage. There was nothing Jack could do to stop her, so he ran instead. Celia's muffled cries would continue to haunt him for years after.

He bolted out of the store and into the street without a care for where he ended up. At first, he just wanted to get away, but as he went, the weight of combined sorrow and guilt caught up to him. He remembered the Bonnie he used to know. That Bonnie was his favorite person in the world. Jack owed a lot to that person, even if she was long gone.

Before he knew it, Jack was running in a conscious direction. The laboratory was the only destination that made sense. It was a near hopeless situation. He was an intern, after all. Still, he felt compelled to at least try and research a cure or remedy for Bonnie. Perhaps there was a way to make her less of a monster and more like her old self.

"There has to be a way to help her. I owe her that much."

Little did Jack know the danger waiting for him at the lab. He and Bonnie had been found out, and a trap had been set.

10 - Dreams Really do Come True

"I need to stop," Alex whined. "This is wrong!"

His resistance was adorable. It was so sweet and so impotent.

They were both naked now, laying in Claire's bed. Alex loomed over Brynn with a look of pure conflict on his face. As much as Brynn now disliked her sister, she still loved that Alex fought for her. Him being virtuous was so hot, and it made the coming downfall even hotter.

"I know babe, you're trying so hard," Brynn gently stroked her man's cock.

Alex was much smaller than the dicks Brynn was used to, but she didn't mind. He still felt good in her hand, and he would grow much bigger soon enough.

"I'm not your babe, Brynn. I can't do this. It's not right - ugh!" Alex squirted a little load of precum on Brynn's magnificent chest as he tried to wiggle away.

Brynn had already coaxed one orgasm out of the man by accident. On impulse, she stuffed his cock down her throat early on. She milked that mushroom until it blew like a geyser and left not a single drop. That should have been the end of it, but Brynn's new body had a way of keeping Alex's blood hot.

Now they were on the verge of the main event, with Alex's last bits of self-control crumbling. It should have been an easy victory, but Alex's willpower was stronger than Brynn anticipated. God, he really was perfect.

"You'll feel much better once you give in, my love."

"No! Stop it, I'm not doing it!"

Before Brynn could react, Alex pulled himself off of her and stumbled towards the door. Suddenly, the man's self-control went from being a cute quirk to a real danger. If Claire found out what had happened, everything would go up in flames. This was Brynn's last chance to claim the love of her life and she was blowing it. Pure instinct took over.

Brynn sprinted out of the bed and managed to cut off Alex at the door.

"Brynn, stand aside. We are not doing this."

"No!"

"Please don't make me lay hands on you."

Alex puffed up his chest and took a step forward that was clearly meant to signal menace. Instead, Brynn just saw his trim body and still dripping cock. She saw the boyish good looks she fell in love with all those years ago. She wasn't letting this end here.

"Go ahead and do it! Do you have any idea how long I've craved your touch? Slap me, shove me, I'll still relish it. I love you Alex. Why is it so hard for you to love me back?"

Alex's expression softened.

"It's not hard at all. If anything, it would be way too easy to love you."

"Then why won't you?!"

"Because it's wrong!"

"How can love be wrong?"

Alex rested his hand on Brynn's shoulder. It was a touch that hovered in the perfect medium between soft and firm, and the comfort it gave Brynn nearly made her forget herself.

"Trust me, Brynn. You don't want me as a lover. Hell, I don't even think I'm worthy of Claire, and she has pretty low standards."

This forced a sad little giggle out of the girl.

"You're really not going to do it, are you?"

Alex shook his head gravely.

"Damn, I thought I had you there."

"I thought you did too!"

Brynn felt her old self rushing back. Her new boobs and curvy figure meant nothing in the end. Alex was simply too virtuous to fall for her. She was a wretch and a loser, and she certainly didn't deserve him.

How dare you expect your dreams to come true, Brynn? Once a mouse, forever a mouse.

In the end, the infection meant nothing. It didn't help Brynn win the man of her dreams, but instead gave her false hope. She wasn't Brynn 2.0 or Brynn 3.0, she was simply Brynn. A bookworm destined to lose out on the one person she loved.

"You won't tell Claire, will you?" Brynn felt like a child trying to get out of timeout.

"Hell no, she would kill both of us."

Brynn managed a weak smile. Perhaps it was better like this. The fact that Alex resisted proved that he was every bit the man she dreamed he would be.

"You're too good. I hope that--ugh!"

Brynn clutched her abdomen as a fierce pain erupted in her core. It was the exact same feeling she felt on the night of the dinner when she attacked Bonnie's poor intern. Her muscles twitched and seized rhythmically as if her body was trying to force something out through her vagina.

"Brynn, are you okay?"

Alex, ever the gentleman, grabbed the girl and held her steady. It would be his downfall.

"I can feel something inside of me!" Brynn moaned.

Something released deep within Brynn. A gush of hot liquid spewed from her pussy, then something else emerged. A fat, wiggly mass surged down her birth canal. She felt it for only a moment before it burst out of her.

"What the fuck?" Alex stumbled backwards and tried to get eyes on the object, but by then it was already too late. "Fuck!"

Brynn watched the scene unfold with a mix of horror and fascination. Her excretion was another worm. Unlike before, when she released an entire pack of the buggers, this time she only squirted out one. The new worm was larger than any Brynn had seen previously. It was nearly two inches long, looking like an overfed slug.

"Brynn, help! It's crawling on my... ugh! Oh God!"

The worm slithered up the length of Alex's still erect cock and then jammed itself into the slit of his glans. It was too big to fit all the way, leaving the little wiggly tail sticking out of the man's cock.

"It's ripping me apart! It hurts. Brynn, do something!"

Brynn simply stared as the worm permanently rooted itself to Alex's body. There was nothing that could save him now. Soon enough, the worm would change him. His muscles would grow. His cock would thicken. It was too much for Brynn to bear.

"Brynn?" Alex sobbed.

When she touched him, the worm responded. It pulsated its body, pumping something or another into the man. Whatever it was, it seemed potent. Alex's eyes rolled back in his skull at the slightest stroke of his cock.

"I'm sorry, Alex. I tried to be a good girl, but I've come too far."

Brynn guided her lover's cock to her entrance. Alex begged her to stop even as his hand wrapped around her buttocks and his hips thrust forward. Then he plunged inside of her and the whole world went blank.

11 - The Tribe Expands

"Jack? Hey where have you been?"

Jack cringed when he heard the voice. His new body was painfully obvious beneath his old clothes, and Kit Lacourse was far from gentle in her bearing.

"Hey buddy, are you okay?"

Jack hurriedly covered his chest with his arms and turned away from Kit.

"I'm fine. Leave me alone."

"Are you crying?"

Jack felt his cheeks and felt the drying tears. He could only imagine the scene he made running down the street, his new boobs bouncing this way and that while he sobbed like a little girl. How humiliating.

"I said I'm fine!"

Jack reached the back entrance of the lab and swiped his key card, hoping to God doing so would finally get Kit to leave. Unfortunately, this was Kit he was dealing with. Despite looking like a rainbow haired pixie, she had a will of steel.

"You don't look fine," Kit shoved herself into the doorway behind Jack. "You have dark circles under your eyes and bruises all over your wrists. Did someone do something to you?"

Jack hadn't noticed the bruises. Bonnie's grip strength was terrifying, so it wasn't surprising that she left her mark.

"You're not supposed to be in here, Kit! We both could get in trouble."

While this was technically true, it wasn't Jack's real worry. If Bonnie decided to return to the lab and found Kit here, he knew exactly what she would do to the poor girl.

"It was those asshole meatheads, wasn't it?"

When Kit got on a righteous crusade, it was impossible to pull her off of it. It was sweet in a twisted sort of way.

"I'm okay, Kit. You need to leave!"

Jack hoped walking to the actual lab would finally convince Kit to leave, but she followed him down the hallway. Luckily, the place was abandoned, and no one else saw them.

"I'm not leaving until you tell me what happened so I can make those assholes pay."

Jack lost his temper. This wasn't helping him at all. Just as he stepped into the doorway of the lab, he whirled around to give her a piece of his mind, inadvertently revealing his new bosom in the process. He just had time to watch Kit's jaw drop when a pair of meaty hands yanked him backwards.

Jack fully expected to see Bonnie holding him in her arms. Instead, he gazed up and saw Brett. Panic set in.

"Well, well, well. If isn't sissy-boy."

The musclebound jock threw Jack to the ground. Kit immediately saw red and charged into the room without a second though. Brett lifted her by the throat like she was made of styrofoam.

"Hey, it looks like we get to finish what we started!" Zander quipped.

Jack looked around in horror and saw four muscular dudes. One was named Shawn. Jack didn't know much about him, but he was a friend of Brett and Zander's, which made him bad news. Then there was a darker skinned South Asian man that Jack didn't recognize at all.

Kit flailed wildly, but her punches and scratches did nothing against Brett's tough physique. It was clear by the bulging erection in Brett's pants what he intended for the girl.

"Where's your scientist friend?" Shawn asked. "I want to speak to her."

"She's out sick," Jack lied.

"Call her. Tell her to come in."

"No."

Shawn cracked his knuckles and took a step forward.

"I really don't want to hurt you, but I will if need be."

Brett threw Kit to the ground and pulled his cock out. Zander followed suit. Things were going from bad to worse.

"Fine, I'll call her. Just let Kit go."

"Not a chance," Brett said. "Shawn and Ravi have already called the hot scientists, so I'm taking mouthy here as a consolation prize."

Jack wracked his brain for a solution, but nothing came to mind. Then he felt his new breasts spreading out on the cold tile floor and it all clicked.

"I can get you a hotter girl!" He said. "Way sexier than that scrawny lesbian."

Brett raised an eyebrow, "oh?"

Jack nodded.

"She's, um, blonde, and cute, and she's got a nice rack."

"You better find her sooner rather than later or I'm taking a plunge into rainbow sparkles here."

Jack stood up and clumsily pulled his shirt off. The cool air immediately made his engorged nipples stand erect. He didn't feel sexy or womanly, but his display certainly caught the men' s attention. Four erect cocks turned in his direction.

"Holy shit, I thought that was a dude," Zander tittered.

"He is a dude... or at least I thought he was," Brett muttered.

Jack pushed his chest out, making his new breasts jiggle slightly and tried to put on his best sultry look. He took his pants off and turned his plumping ass in their direction for good measure. It was ridiculous and humiliating, but if it saved Kit, it was worth it.

"Do I look like a dude to you idiots?" Jack said, cupping his breasts and pushing them together. A mad tingle erupted in the two swelling orbs. "Do men have D Cups?"

Jack figured a D would inflame the men's desires more than a C Cup, and the lie would become true soon enough if the itchiness and pain in his breasts was any indication.

Jack kept his crotch turned away from the men, hoping to hide his male genitals. Glancing down, he saw that his penis had shrunk again, and now looked like little more than a pink nub. The place where his scrotum used to be hurt like hell, and something wiggled beneath the skin. He did his best to ignore the pain. Kit came first.

Zander was the first to break, followed quickly by his partner, who dropped Kit like a sack of bricks. Instead of running the girl simply sat up and gaped at Jack in much the same way as the men.

Damnit, you were supposed to run away!

"Where the fuck did these come from?" Brett cupped Jack's right breast, making him feel so small and frail. He was a piece of meat to these guys.

"I've always had them, I just don't like showing jerks like you!"

Brett responded by casually slapping Jack across the face. It was a light, low effort blow from the musclebound freak, but it filled Jack's vision with stars.

"Hey, cut that out!" Shawn snapped.

"What? These cunts won't stop mouthing off to us. I don't like it."

"And I don't like you hitting chicks."

Credit where credit's due, Jack supposed. Shawn certainly seemed like the most put together of the bunch, all things considered.

"Come on, she started it! What am I supposed to do if she mouths off?"

Suddenly, the laboratory door flew open.

"Nothing. You will do nothing!"

Jack didn't know whether to feel horrified or relieved at Bonnie's arrival. He had so many conflicting emotions pinned on his mutated lover, turning his heart into a gruesome colosseum.

The four men stared at the newcomer in shock, giving her the perfect opening to strike. Jack couldn't believe how quickly she moved, closing the gap between herself and Zander and Brett in a second. With them all close together, Jack could clearly see that Bonnie outranked the men in size and strength. She seemed even bigger than she had in the department store. Somehow, she managed to cobble together an outfit out of a very large men's t-shirt and sweatpants, but the clothes already seemed too snug on her body.

Bonnie grabbed Zander and Brett and slammed their heads together hard enough to knock out the former and daze the latter. The South Asian man made a little war cry and charged and locked burly arms with Bonnie. The two studs struggled as if locked in some kind of primal mating conflict, muscles bulging and voices grunting. Bonnie's opponent seemed to know what he was doing better, attempting some kind of Jiu Jitsu hold. Unfortunately for him, Bonnie outweighed him by a good forty or fifty pounds, and raw strength determined the fight. Eventually, Bonnie managed to toss the man into a nearby table hard enough to put him out of commission.

By then, Brett was climbing to his feet, apparently looking for round two. Bonnie didn't give him the chance, instead grabbing him by the throat and holding him at arm's length. Bonnie's arm muscles flexed and bulged, showing off their supreme size and power. Those arms were so unnatural, as if they had been ripped from the most absurd superhero comic pages.

Why does she have to be so hot? I just keep getting sucked back in.

"You don't hit my girl, do you understand me?"

Bonnie's grip didn't exactly give Brett the ability to respond. The man was turning blue from the suffocating pressure.

As horrified as Jack was by Bonnie's transformation, there was something a little thrilling about having his honor defended by such a hunky, sexy beast.

She called me her girl...

Shawn approached Bonnie cautiously with his open palms raised.

"Do you wanna join your friends, buddy boy?" Bonnie said.

Shawn, perplexed, held up his phone and compared what he saw on the screen with a hulking figure before him. As the recognition dawned, his confusion deepened.

"You're Bonnie. You're the scientist we were trying to find."

Bonnie tossed the defeated Brett aside like an unloved toy and turned her full, fiery attention on Shawn instead.

"Why were you trying to find me?"

"I was going to fuck and infect you. We wanted to stop you from studying this thing."

Bonnie's face twisted in a wry smile.

"You wanted to fuck me, eh? Tell me, are you still feeling that way?" Bonnie whipped out her half erect cock and gave it a pump for emphasis.

Shawn's eyes nearly bugged out of his skull when he saw Bonnie's manhood.

"You're a man? How the fuck did that happen, are you trans?"

"No, I was just an ordinary woman. It turns out, this parasite can do a lot more than any of us thought."

Jack felt the air in the room shift. It was almost as if Bonnie and Shawn were synchronizing, which didn't bode well for either him or Kit.

"You're one of us now."

"If anything, I'm the improved model," Bonnie flexed her goliath muscles. "So tell me, do you still want to fight me?"

"I could, but I would probably lose. Besides, why fight my own kind? If you're anything like me, I bet you're horny as hell. I know a place where you can have all the girls you want?"

Bonnie's erection surged to full mast, "Now you're talking."

No, this wasn't supposed to happen...

Jack felt a tug on his wrist and turned to see Kit. In the commotion, she managed to sneak over to reach him.

"Come on, let's scram while they aren't paying attention."

Jack should have known better. He saw a chance to break away from the insane nightmare of the parasites and jumped on it, failing to realize his selfishness. Kit was offering him a lifeline, not realizing he was about to pull her under.

The pair shuffled halfway across the room before Bonnie noticed them in her peripheral vision. Her speed was terrifying. Her new muscles seemed to exceed human limits. Bonnie's grip on his wrist was like a steel manacle.

A lesser friend would have fled. Puny little Kit was no match for a beast that was nearly seven feet tall and packed with muscle, but she didn't seem to care. She rushed forward like a rabid animal, teeth bared, and chomped into Bonnie's hand. To Jack's surprise, Bonnie let go and stumbled backwards, nursing her hand, giving the illusion of freedom. It was short-lived.

Just as Kit tried to drag Jack away, and tearing pain erupted between his legs. He clutched at his crotch to find the skin splitting. Blood splattered the floor as his tightened scrotum separated, transforming into a rough labia. Then the contractions started.

It felt like a giant hand was squeezing Jack's abdomen like a toothpaste tube. Something was wiggling down Jack's insides. Something small and fierce.

Like some sexual knockoff of Alien, the little monsters exploded out of Jack's mutated crotch in a gout of blood. Period blood, to be specific, although he didn't know it then. Jack's worms were bigger than the earlier samples, and more distinctly phallic as well. The nubs at their base were more prominent and covered in fleshly, hair-like tendrils. Most notably, in place of a fluttery tail, these worms terminated in little gripping spikes seemingly designed for latching.

Bonnie, ever the scientist, plucked one of the mutants up and held it up to the light. She muttered to herself like she used to when Jack and her worked together, and for a moment, Jack didn't see the hunky shemale that raped him, but instead the quirky, nerdy goddess he fell for.

Then the illusion broke hard.

Kit was brave, but this was her limit. A fight was one thing, but parasitic worms and forced sex changes were another.

"What the fuck?" She backed away as if to leave.

Bonnie had different plans, seizing Kit by the arm and yanking the girl hard enough to make her cry out in pain.

"Get the fuck off of me! I'll kill you, you fucking rapist pig!"

"You're so feisty! I think you'll make a perfect fit for this little guy."

Kit turned pale as a sheet.

"Don't waste your time. That thing doesn't want her," Shawn said.

"Are you sure about that? Watch and learn."

Bonnie unceremoniously jammed her meaty hand down the waistband of Kit's black leggings. The poor girl screamed in horror, and then pain, but it was too late.

Jack didn't object or try to stop the horror. He was in too much pain, and even if he wasn't, he was too afraid. He was a frail, delicate little creature in the midst of dangerous giants, and soon enough he would have to deal with one more of their kind.

12 - Fucking Cops

"You keep talking about this report. I don't see a report on my desk."

Claire squirmed in her seat as the cop fixed her with his bloodhound eyes. He was one of those southern good ol' boys with a sandpaper temperament.

"It is still in progress. If you contact the scientist I've referenced, I'm sure she'll give you a summary of her findings."

"Yeah, I called her multiple times, left some messages, but she never responded."

Bonnie could be absentminded when stuck down a rabbithole, but ignoring the police was a stretch. If Claire hadn't spoken with Bonnie the night before, she would have assumed the worst right off the bat. Instead, she was baffled, and more than a little angry.

I get that science is important, girly, but this is too. Brynn and Alex are missing, I can't have you going AWOL.

"I will try to contact her. I'm sorry for the inconvenience, truly. If I may explain my story a little further I can--"

The cop held up his hand to silence her.

"Ma'am, do you have any history of mental illness?"

"What?! My friends and I have been stalked and attacked, and now my sister and boyfriend are missing and you're accusing me of being a whackjob?"

"Listen ma'am, you keep vaguely referencing some conspiracy or something. You gave me contact information for a scientist who never picked up, and your partner suddenly skips town. It all just seems suspicious."

"Suspicious?! I told you, my sister and boyfriend are missing. That's what's important. That's what I want you to focus on!"

The cop let out a deep, rattling sigh that sounded like a brisk autumn wind.

"How long have your sister and boyfriend been missing?"

Claire knew how it sounded.

"A couple of hours."

"Listen, do me a favor. Go home and wait for them. Take your time, maybe a couple of days. Maybe it'll all work out. I would hate to have to get more involved than is," the cop paused for a few seconds. "Necessary."

There was a darkness to the cop's words that made it clear things would end poorly if Claire came back too early. Her last glimmer of hope died away, leaving her feeling sick to her stomach.

"Fucking cops," Claire sneered onced she was out of earshot of the station.

There was no point in calling Brynn or Alex. Claire had already done so dozens of times to no avail. At this point, Bonnie seemed like her only option. Claire muttered under her breath as she selected her friend's contact in her phone. If Bonnie really was just trapped down another autistic rabbit hole and shutting out the world, there was going to be hell to pay.

Of course the call went to voicemail. That was just Claire's luck.

"Damnit, Bonnie! I swear to god."

Under Claire's anger, there was a deeper sense of dread. It was comforting to imagine Bonnie was just being an idiot, but Claire knew her friend too well. Bonnie got distracted, but that didn't mean she didn't know how to lock in when the stakes were high. She had a PhD for Christ's sake! Something was very wrong, but Claire wasn't ready to face the truth yet.

Finally, Claire's anger withered into fear.

"Oh God, Bonnie. What have they done to you?"

13 - The Alpha (She) Male

The other males undressed as soon as they entered the small college townhouse. They were all hulks by most definitions, but as Bonnie looked them up and down, she realized she outsized every last one of them. She stood taller, and her muscles were fuller. It still made her head spin to think she was a puny little woman just a day prior

Bonnie soon joined her fellow males in nudity, drawing shocked gasps as she did so. Her growth had slowed, but not stopped. In the last few hours, she had packed on extra muscle and height, as well as another inch or two between her legs. Paradoxically, her boobs were also bigger, leaving her with a very confusing figure.

A musky scent filled the room. It was the musk of sweat and desire. As Bonnie stood there, Rex inflated and then twitched rhythmically. Glancing around, Bonnie noticed that every other cock was doing the same thing. It was like they were synchronizing into a breeding frenzy.

The redhead set it off. She bounced into the room like a bosomy ginger cloud, immediately catching Bonnie's eye. She wasn't a dead ringer for Claire, but she was close enough to trigger something deep inside Bonnie's psyche.

"Hey Shawn, did you nab that scientist chick? I wanna see if she can help me with this awful summer chem class."

Bonnie caught the girl's eye. For a fleeting moment, the girl licked her lips and stared lustfully at the towering wall of muscles. Then, as she noticed Bonnie's absurdly voluptuous breasts and androgynous features, her jaw went slack.

"About that," Shawn said. "Apparently, this whole thing is weirder than we thought."

Bonnie didn't wait for the girl to respond. She grabbed her and pulled her close, prompting an adorable blush on the girl's pale cheeks.

"What are you?"

"I was a woman. Now things are... more complicated."

"What?! No, I'm not gay, I don't like women."

Bonnie pressed her throbbing worm cock against the girl's inner thigh. Her precum was already leaking sumptuously, dappling the girl's creamy skin. The redhead didn't look much like Claire, but if Bonnie squinted, she could get her imagination to do the rest of the work.

"I'm not a lesbian," the redhead repeated.

"Neither am I," Bonnie chuckled as she yanked the girl's pants down.

Of all the changes to Bonnie's body, the one that bewildered her the most was her connection to Rex. She still remembered plucking the worm off of Jack and holding it up to the light of Claire's kitchen. Little did she know at the time that her fate would be permanently intertwined with the small creature. Of course, Rex was far from small now. He now extended nearly fourteen and a half inches from Bonnie's crotch. Bonnie traced the plump veins running up the length of the worm and felt the thrilling tingle the contact brought her. What once had been a separate organism was now Bonnie's most intimate body part. Not only had the worm joined with her, but also reshaped her, filling her with primal instincts and the strength to act on them.

Now it was time to act on those instincts. Bonnie plunged into the redhead, feeling the slow stretch of her pussy around her behemoth cock. The satisfying squeal ripped from the redhead's mouth was like music to Bonnie's ears. Once in, Bonnie buried herself in the crook of the redhead's neck and took a big whiff of the girl's skin and sweat. She smelled a little like Claire when she had just come back from the gym covered in sweat, sweet and sensual.

"Oh God, you're huge!" the redhead sobbed. "It's too big, I can't handle it!"

The girl's whimpers were music to Bonnie's ears. They made her feel so unbelievably powerful. This little slut had been taking it from all of these guys, but Bonnie was the one to push her to her limit. Damn was that satisfying.

"Don't worry, you'll get used to me."

"I'm not gay! I don't like... women, so why is my body... so hot!"

The poor thing didn't know how to handle Bonnie's strange, mixed up body. All of the things the girl had been taught to reject were tightly coupled with all that she craved. It was a vulnerable state for her, one in which her mind was likely soft and malleable, which gave Bonnie a dirty idea.

Bonnie grabbed the redhead's right hand and lifted it to her huge, heaving breast. At first, the girl tried to yank her hand away, but Bonnie was much too strong for her. Her fingers twitched and groped clumsily. Then Bonnie picked up the pace of her thrusts to an absolute frenzy, pounding the ginger's pussy into a frothy mess.

"No! No! It's... wrong... but... so... goooooood!"

The redhead cupped Bonnie's breasts, at first gingerly, and then with increasing frenzy. Delicate fingers pinched and poked the she-behemoth's turgid nipples. The girl's brain rewired in real time, coalescing all sexual desires on Bonnie's hybrid sex.

With each thrust, that boiling, tingly, unholy cauldron of pleasure in Bonnie's worm-cock boiled to new heights. Bonnie's balls tingled and her muscles twitched. The drumbeat of testosterone pushed her ever closer to her limit.

The ginger girl was so creamy and soft, so supple and bouncy. Her tits were so big and perfectly shaped. Bonnie watched jiggly white flesh bounce up and down with religious devotion. She finally understood the male obsession with boobs. They were just so damn beautiful! So grabbable and squishy. They signified so much in a compact, fleshy package: beauty, fertility, and sexual superiority.

Somewhere between thrusts, Bonnie's imagination blurred with reality. The redhead's moans shifted to something more familiar. The moans became those of Bonnie's oldest friend. Claire was so special to Bonnie that it almost felt like lusting over her sister. It was wrong and raw, but Rex had prepared Bonnie for this, transforming her mind so that every forbidden taboo became a source of intense lust.

Bonnie looked down and saw Claire underneath her. She imagined unloading her potent genetic material into her best friend. What would happen if she fathered a child with Claire? How much closer would their bond become?

The thought ripped a terrifying, ball puckering orgasm from Bonnie's mutated sex. She roared in her darkened voice as she unloaded pump after pump of hot, gooey seed into the redhead, reducing her mate into a babbling, slobbery mess. Bonnie still couldn't wrap her head around these sensations. She was fucking another woman, stretching her pussy to its limits with a thick, meaty cock, and filling it with spunk. It was a forbidden fruit Bonnie had eaten whole.

The redhead was still mindlessly groping at Bonnie's tits as the scientist withdrew her manhood. For a normal guy, sex would be off the table for the better part of an hour, but Rex had gifted Bonnie superhuman stamina. The worm-cock twitched greedily, commanding Bonnie to find another mate. Luckily, another was close at hand.

She was blonde and beautiful, maybe a little bitchy. Bonnie recognized her type. She was probably a cheerleader in high school and top dog in her sorority.

"What are you looking at?"

The blonde froze, and Bonnie took her.

Three girls later and Bonnie finally settled a little. She was still hard as a rock, but the bite of her instincts abated somewhat. She finally pulled out of a bosomy brunette and glanced around. The men were all looking at her. She fully expected hostility, but instead felt a wave of mutual respect.

"Damn, you really are one of us!" Shawn said.

"It felt so good! I think I'm addicted."

"That's the spirit," the dark skinned man cheered. "I feel the same way. I just want pussy, pussy, pussy all the time!"

These were Bonnie's brothers. Fellow males of the tribe who all shared the curse of lust. Suddenly, Bonnie felt a little more comfortable in her new skin. It was weird to play for the other sexual team, but she had to admit it felt amazing.

With her head cleared, Bonnie finally decided to pay Jack a visit. Now that her desires were blunted, she felt more than a little guilty for how things left off between the two of them.

Jack had sequestered himself in a small bedroom with his friend. When Bonnie entered, she was immediately met by his fierce, resentful gaze. She looked beyond him to the bed and saw a small lump under the covers. She was very curious what would become of that lump.

"Having fun?" Jack sneered.

"Come on, don't be that way."

Bonnie sat down next to Jack, causing the entire bed to slump downwards. The lump under the covers let out a pained little squeak. Jack scooted a couple of inches to the side. Bonnie couldn't believe how much she dwarfed the boy now. There had been a time when he used to be taller than her. Now, she made him look like a child in comparison to her bulk.

"I have nothing to say to you."

"I don't think that's true. I think you have a whole lot to say to me, all of it boiling under the surface. Come on, out with it."

Jack crossed his arms over his ballooning chest and pouted. His breasts seemed slightly larger than Bonnie remembered, but not as large as she expected. There was still a good deal of boy left in her intern, almost as if he were actively resisting his transition.

"Fine. Bonnie, you're scaring me. This parasite has corrupted you!"

"Why? Because I fucked those pretty girls out there?"

"You raped Celia!" Jack squeaked.

"Who?" The name drew a complete blank for Bonnie.

"The clerk! You forced yourself on her without even bothering to learn her name. That worm is controlling you. It's made you do things you never would have done before."

Bonnie couldn't argue with Jack on that point. The more Bonnie thought about it, the more it set in what she committed. It was unforgivable, and the worst part is that Bonnie knew she wouldn't be able to resist the temptation if it arose again. She felt a bubbling of guilt, but Rex quickly punished her for the glimmer of humanity. It wasn't just Rex's conditioning, either. At this point, Bonnie's biology had changed so significantly that her new urges short circuited every last moral faculty. It didn't help that Bonnie was essentially going through a second puberty. The surge of hormones designed to empower and virilize her body simultaneously assaulted her mind with a constant flood of carnal desires. She was like a huge, horny teenage boy with all of the associated moodiness and perversion.

The shape under the covers stirred. Bonnie watched a hand reach out and grab an extra large tub of peanut butter placed on the bed as a kind of twisted welcome gift for Jack's infected friend. There was already a pile of discarded snack wrappers. Bonnie's test subject was already suffering from the same terrifying appetite as her, apparently.

"How is she doing?" Bonnie asked, hoping to change the subject.

"How could you?" Jack glowered. "It wasn't enough for you to be corrupted. You had to go and corrupt her as well."

This Bonnie felt zero guilt over. She was intensely curious about how the new girl would change compared to her own metamorphosis. Plus, Bonnie was looking forward to not being the only girl with a cock in the bunch.

"How far along is she?"

"I have no idea. I've given her privacy. It's the only thing I can do for her at this point."

This made Bonnie chuckle.

"You're talking about her like she's terminally ill. She's just growing a cock, Jack."

"She's growing much more than that! You turned her into a monster."

The words struck Bonnie like a bullet.

"You think I'm a monster?"

For the first time since they began talking, Jack softened. As mad as he was, he still cared deeply for Bonnie, and the sweet, beautiful look on his face eased the blow. He really was shaping up to be a stunning beauty.

"I think you've let that thing between your legs take control of you. It's twisted you and made you do things you otherwise wouldn't to the point where I don't feel safe around you."

"You don't feel safe? When have I ever hurt you?"

"Are you serious? This whole thing started when you forced yourself on me!"

"I thought you loved me. You told me I had become a perfect match for you."

"I do love you! Why do you think it hurts me so much to see you do these things?"

Bonnie sulked in the corner. A large part of her just wanted to pin Jack to the bed and make things better through sex, but she resisted that urge with all her might. She didn't want to push him away any more.

"I guess I'm just a monster. Do you hate me for it?"

"I already told you I love you! I don't blame you for any of this, but you need help, Bonnie. We both do. Everyone in this godforsaken house needs severe medical and psychological intervention. There has to be some way to reverse this."

"You're resisting it. Why?"

"What kind of stupid question is that?! I don't want to end up turning into a girl. You should fight it too. You're too good of a person to become just like those meatheads out there. If we can hold out long enough, maybe this can be reversed."

"Reversed? Jack, look at me," Bonnie held Rex up for him to see. "This cannot be reversed. The parasite changed me on a genetic level. I have balls, for god's sake! I'm not going back to the woman I once was, and quite frankly I don't want to."

"You're nuts! I don't want to become some chick. I'm not going to let this thing corrupt me like it's corrupted you."

Bonnie pitied the boy. He had so much potential boiling under the surface. Why did he cling to a male identity that previously meant so little to him? It made no sense. Perhaps he needed a little push.

Bonnie cupped Jack's cheek and kissed along his jawline. She fully expected him to push her away, but instead he sighed sweetly. As much as he talked a big game, he still had the hots for her.

"You should let it corrupt you," Bonnie said, kissing down Jack's neck. "It feels so raw and delicious."

"No! I won't let it. I'm not turning into a chick."

Bonnie grabbed Jack's breasts and squeezed, making him shriek.

"You're already a chick, Jack. You have nice, full breasts," Bonnie reached down and ran her finger along his new slit. "And don't forget this!"

"Stop!" Jack's words and tone were at odds with each other.

"I'm sorry I hurt you, Jack. I really am. My body and brain have changed so quickly that I've forgotten myself. Please forgive me."

Bonnie pressed her finger into Jack's entrance.

"Oh!"

"I'll try to get myself under control for your sake. You see, I really like you, and now that you're a girl, we match better than ever."

"I'm not a girl!" Jack squeaked.

Bonnie shoved her whole finger in the moaning little bitch.

"Sure, sweetie."

"I don't want to be a girl," Jack sobbed.

Bonnie grabbed his wrists and lowered him to the bed. It was a firm gesture, but not forceful. She didn't want to take him like she had the others. He was too special to her. There was a funny affinity blossoming in her heart for the intern. Sure, he was pissed at her now, but the blush in his cheeks told her his heart was still hers.

"You aren't yourself, Bonnie. You never would have pushed me like this before."

"That's not true at all," Bonnie pressed herself against Jack's new entrance. It wasn't a vagina so much as a wound, but it still did the job. "I've been pushing you since we met. I think that's why you fell for me."

Bonnie thrust so just her glans filled Jack's opening, ripping a delicious little yelp from his lips. The more Bonnie played with this thing, the more she loved it. Sticking it in things just felt so damn good!

"Not like this!"

"Perhaps, but I definitely pushed you out of your comfort zone," Bonnie emphasized her point by teasing Jack with just an inch of back and forth thrust. "You see, Jack, you're a very passive person. From what you've told me, your dad always pushed you, but it doesn't seem like he ever respected you. I'm sure plenty of people have given you respect, but few have ever pushed you. You crave both, and I nurtured you with them."

"But you've changed! This thing has turned you into... ugh... oh God! Into a man!"

Bonnie thrust with all her terrible might. A moment later, she heard the satisfying slap of her testicles on his swelling buttocks.

"I'm not a man, I'm something much better. Look at me, Jack. Feel how massive my muscles are, and look at these tits! My skin is softer than it's ever been, my face is bright and blemish free. I'm stronger and more virile than those men out in the living room, and prettier than most women. I'm humanity perfected!"

Jack tried to say something about resisting, fighting the urges, blah blah blah. His message was undercut by his girly little pants and moans as Bonnie very slowly withdrew her cock to the head.

"I think you can be the other side of my coin, Jack. The same mutagenic forces that gave me this power could transform you too, if you let it. The parasite has already left its mark. You're very pretty, but you have so much more room left to grow!"

"I don't want to be a girl," Jack moaned. "I don't want to be weak!"

"Weak? Who said anything about being weak? If you give in, I'm sure you'll be stronger than you could ever imagine. After all, beauty is a form of power, isn't it?"

"You're... not wrong..."

"Face it, Jack. You were never really happy being a boy. That's an advantage you have over me in this craziness. Rex really had to fuck with my head to make me okay with being male. Meanwhile, you could just embrace this..."

"But what would my dad say?!"

"Fuck your dad! He's an asshole. The only male whose opinion you should care about from now on is mine, and I say you should become a goddess. Then you can wrap all the men who ever tormented you around your finger. The world could be ours, together, if you just let go..."

"No... no... yes! Yes, I want it!"

That was all Bonnie needed to hear. She surged into Jack's depths like a raging river. She imagined her mutant swimmers joining up with the existing infection in the intern's core like reinforcements for an apocalyptic battle.

Bonnie left her new girlfriend in a twitching heap. Jack still needed time to transform, and there were still girls Bonnie hadn't tasted yet. The secretary from Claire's work was one of them. Bonnie remembered her as a nerdy rat of a woman, but the infection transformed her into a whole new woman. Her tits were the thing of dreams.

Just as Bonnie exited the room, she heard the voice of Jack's friend. She sounded hoarse and terrified. Each word dripped with pain.

"Oh God, it's getting bigger!"

Bonnie beamed with pride.

"Welcome to the party."

14 - A Balloon in the Wind

Shripppp!

Alex's biceps burst out of his sleeves just as they reached the house. He was growing so fast Brynn could practically see his muscles growing in real time. While it was a panty-soaking sight, it filled Brynn with more than a little trepidation.

The good news was that Alex took to the parasite very well. Almost immediately, he lost control and plunged into Brynn's pussy. That first love making session was the closest thing to heaven on earth for the young beauty. Alex worshipped her as he plumbed her depths, remarking that she was the "hottest fucking girl" he ever saw, and that her tits were "carved by the gods". It was hokey, but Brynn didn't care. She finally had her man, and he was obsessed with her!

As Alex released inside of Brynn, she hoped this would be the moment that anchored them together forever.

Please let me bear his child. That would be a dream come true!

The cuddly, soft afterglow Brynn expected never came. Sex seemed to give the parasite an even deeper foothold in Alex's body, and the transformation was well under way. Swollen veins stretched across his skin, delivering the nutrients needed to make the man grow, grow, grow! Brynn salivated at the prospect of Alex growing even hotter.

Unfortunately, there were mental changes to Brynn's lover as well, and those were less pleasant. Alex's psyche seemed to be ripping itself apart as his moral compass duked it out with his uncontrollable desires. He muttered to himself and cradled his temples as tears streamed down his cheeks. Brynn felt her first pang of regret as she watched.

"My dear love, are you okay?"

A gentle brush of Alex's arm was enough to set him off. He dug his fingers into Brynn's hair and forced his cock, which seemed thicker and veinier than before, down Brynn's throat. What followed was devoid of any grace and or tenderness.

"Take it, you fucking whore! You did this to me, and this is your reward!"

Brynn didn't remember much of what followed. Alex didn't give her much time to breathe, and by the time Alex finished, she was close to blacking out. She collapsed in a haze as rope after rope of hot seeds slathered her face. In that muck, Brynn tried to piece together how she got here. A week ago when she boarded the plane to Florida, she had been a prudish virgin with a flat chest. That poor, innocent girl never would have imagined she would be laying in bed with a man as he splattered her big pornstar knockers with sperm.

Post nut clarity was enough to drive Alex towards a mental breakdown. In the lull of his enhanced sexual desires, his guilt erupted like a volcano.

"Oh God, I'm so sorry, Brynn. I can't control it. I didn't mean to hurt you."

Brynn sat up and scooped a dollop of Alex's jizz off of her breasts. The stuff wasn't nearly as thick and cloudy as Shawn's was, but it was still precious. This was Alex's essence. As startling as Alex's transformation was, he was still the love of her life. She gave his seed a taste and swooned.

"Yummy."

"Claire is going to kill me," Alex looked down with a start as his growing cock rocketed to full mast. "Claire..."

Brynn had come too far to share this perfect man with her sister. She rushed forward and grabbed Alex by the cock. Immediately, she had full control over him.

"You know my sister. She'll flip if she sees us together. We need to get out of here."

"Where would we go?"

Brynn could think of only one place. By some miracle, she convinced the horny, growing man to get dressed. Already, his clothes were far too small. His body was morphing right in front of her. Alex was already taller and buffer than he had been an hour ago. The rapid growth brought a new element into their dynamic: pain.

The pair stopped multiple times during the long walk to the college townhouse. Alex would pause for several minutes as muscles twitched and swelled and his bones softened. She wanted to help him, but there was nothing she could do. The parasite set the man's body on an irreversible course.

Now the two of them stood at the door like the world's most ragged couple. Brynn was dressed in nothing but a white camisole and shorts that were too tight, leaving almost nothing about her body to the imagination. Meanwhile, Alex's new bodybuilder arms were continuing to tear his shirt sleeves more and more.

It was Kaylee who opened the door. The ginger was almost as much of a wreck as Brynn and Alex. Her eyes were glassy and her hair a wreck. Brynn watched the girl's eyes dart between her and Alex. She couldn't help but notice Kaylee gawking at her chest.

"Can we crash here? I promise my sister won't mess with you guys," It was a promise Brynn was in no position to make, but she was desperate.

Kaylee nodded vacantly and beckoned them in.

The house smelled muskier than ever. The boys and girls were all paired up together, smooching and fucking. In the distance, Brynn heard a strange voice bellowing. The voice sounded too high pitched to be a man's, but it was very resonant and powerful. Whoever it was, he certainly seemed to be having fun.

"Well, well, well, look who came crawling back."

Shawn forcefully spun Brynn around, causing her to jiggle and bounce in ways that were still alien to her. As her front came into view, Shawn's bitter expression melted. Replacing it was one of pure awe. A small flame kindled in Brynn's chest. She loved Alex with all her heart, but she couldn't help but feel a little thrilled at the effect she now had on other men.

"I'm back for good," she said. "I quit taking the medication."

"Music to my ears," Shawn tried to pull Brynn closer, but she wiggled out of his grasp.

"I have a boyfriend now."

Shawn's expression darkened.

"So you got with your crush?"

Brynn nodded.

"He's one of us now. I belong to him and only him."

"Then why did you come here?"

Brynn felt her confidence melt like butter in the microwave. She wasn't exactly in the best position to make demands.

"We need a place to hide out. It'll just be until his transformation finishes and he settles down a little. Things are very intense right now."

"If I can't have a taste of you, you don't get to stay here. Besides, why can't you stay at your sister's place? The two of you could easily force Claire to join us."

Brynn blushed furiously at the idea. The image of Alex rising to full mast at the mere mention of her sister was burned into her mind.

Shawn smirked.

"But then you would have to share him with your sister."

Elsewhere in the house, Brynn heard that odd, androgynous voice howl in what sounded like an earth shattering climax. It was the strangest thing. The voice sounded so familiar, but Brynn couldn't place it.

"We just need to crash here until Alex is done growing and has his self-control back. Then he and I will be out of your hair forever."

Shawn found this hilarious for reasons Brynn could not fathom.

"What then?"

Brynn couldn't stand Shawn's little knowing smirk. Did he have to be such a jealous prick? Brynn wanted to slap that smile off his face.

"It should be obvious. I'm going to marry him."

Brynn trembled with nervous energy. Her whole life felt like it was balanced on a razor's edge. If things fell one way, she earned the man of her dreams, and oh what a man he would be. Everything hot about Alex was being magnified by the infection. He was already perfect, but soon he would be superhuman. If things fell the other way, she might lose him entirely. She had to keep him away from Claire. Her sister still owned a piece of her man's heart. She was the only one that could pull dear Alex away from Brynn.

"Wow, marriage. That's a big step for a high school graduate."

"Snark at me all you want. I think you're just jealous. Your crush crashed and burned while mine is soaring high."

Brynn wanted to see the smile fade from Shawn's face. If he got angry or violent, all the better. Then she could watch Alex pound this asshole into the ground. Seeing her man defend her honor was bound to make her cum like never before.

Alex didn't get angry. Instead, he burst out laughing. It was a cruel, reedy laugh that contrasted with his deep, resonant voice. Brynn wondered if this was a glimpse of what the boy used to sound like before the parasite changed him.

"What's so funny?"

"I thought you were smart, Brynn."

"I am smart, you ass! Now tell me what you're laughing about!"

"You want to keep your crush to yourself, right?"

Brynn nodded.

"Then why the fuck would you take him here?"

At first, Brynn didn't understand. Then she heard the loud, drawn out groan from the living room. It was Alex, and he sounded like he was in extreme pain. She ran and Alex followed, still laughing. When Brynn got to the room, she finally understood.

Alex had Kaylee pinned against the wall. Brynn watched her lover's cock plunge into the redhead at a terrifying pace. The look on Alex's face was downright deranged.

"No!" Brynn sobbed as she rushed into the fray.

It was a ridiculous, futile endeavor. Brynn flailed about, trying her best to separate the two of them. She fully expected Alex to come to his senses and apologize profusely. It would be difficult, but she would forgive him. It was the parasite's fault, after all.

Instead, Alex broke her heart.

With an enlarged, meaty hand, Alex palmed Brynn's face and tossed her on her ass. She landed in a heap, stunned beyond belief.

"You'll get your turn soon, bitch!"

Bitch pierced her heart like a knife. Alex may have been the man of her dreams at one time, but that time had passed. The parasite was in control now.

A hand grabbed Brynn's wrist and pulled her to her feet. The world spun around her as she walked back to the kitchen. With her dreams dead, nothing felt real.

"Cheer up, Brynn. You still have me," Shawn wrapped his arms around Brynn's waist.

Brynn couldn't think of a single word to say.

Suddenly, the sound of loud, heavy footsteps echoed through the house. Brynn looked up in time to see an enormous figure duck through the doorway. Whoever he was, he was enormous, easily standing seven feet tall. He was bigger than the other guys, too, with plump, glistening muscles.

The longer Brynn stared at the figure, the less she was convinced that he was a he at all. The pale skin was so soft and supple. The face had a chiseled jawline, for sure, but the brown eyes were large and feminine. The lips were plump. Cheeks blushing. Then there were the boobs. Huge, buoyant breasts stacked on top of a broad, muscular chest. The person's hair was girly too. The long, flowing brunette locks were sleek and lustrous, done up in a bun that straddled the line between casual and professional perfectly. Brynn recognized that hairdo, along with the voice it belonged to.

"Brynn? Holy hell! I can finally appreciate how fucking hot you've gotten!"

The recognition pushed Brynn's already desperate mind closer to the edge of sanity.

"Bonnie?! What's happened to you?"

"I had a little lab oopsie. By accident, I managed to trick one of your worms that I was male. The worm made that trick a reality."

Between Bonnie's legs, there jutted a truly mind-numbing revelation. The effortlessly beautiful woman Brynn once admired was no longer a woman at all. A thick, twitching phallus jutted from Bonnie's crotch, paired with two heavy, hairy balls. The sight was an obscenely masculine desecration of Bonnie's womanhood.

"That's not possible."

Bonnie got in close so that Brynn could smell her. She smelled musky and sweaty, yet sweeter than a man. Her body radiated a terrifying amount of heat. That thick, throbbing rod of flesh gently brushed Brynn's belly, oozing precum like the trail of a slug.

"Oh honey, you're going to need to adjust your view of what's possible. Now let me get a taste of you."

Brynn took an emphatic step back, only to have her gesture be immediately undercut as she stumbled into Shawn's arms.

"I'm saving myself for my husband."

"Husband?!" Bonnie stared at her in disbelief.

"She brought my boss, Alex, here. She's head over heels for him. He's balls deep inside Kaylee."

Brynn could still hear her love copulating with that dumb whore. The pain on her face had faded, but the heartache never would.

"He made a mistake. It won't happen again. I'll make sure of that!"

Alex's orgasmic moan shook the house. Almost immediately after, Brynn heard the voice of another girl speak in the room over.

"Damn, you're, like, really hot now, boss. My turn!"

Please reject her and come to me, my love. I know it is hard, but find the strength...

"Don't mind if I do!"

Brynn's heart collapsed in on itself like a dying star. The hope the parasite gave her was a cruel trick. Of course it wouldn't work the way she wanted it to.

"Why is he doing this to me?"

"I can't say I didn't warn you," Shawn said, pressing his erect cock between Brynn's buttocks.

"Don't take it personally, Brynn. The parasite is just too powerful. Once it gets inside of you, you lose all self control. In the last few days, I've done things that were unthinkable before."

Bonnie grabbed Brynn under the knees while Shawn held her from behind. Brynn realized what they intended to do too late to stop them. It wasn't enough that the man of her dreams had turned into a sex hungry pig. Brynn too would be condemned to a whorish life of excess. The worst part was that she knew she was about to enjoy the oncoming double teaming.

"Speaking of," Bonnie continued. "I'm going to add to that pile of unthinkable things by fucking my best friend's baby sister."

Bonnie was a revelation. Through the pain brought everything into focus. Brynn remembered a fall festival from long ago, when she was a child. There was a balloon shaped like a pumpkin that she utterly fell in love with. Her father spent nearly thirty bucks winning it from the game stand. It was everything Brynn ever wanted, then she accidentally let it go as they were walking to the car. She watched it soar into the sky with a desperate sense of helplessness. She felt that same helplessness now as her body was ravaged by a beast of pure sexual domination.

Dad was disappointed about the balloon. Mom was pissed. Claire was the only one who hugged Brynn and told her it was going to be alright. They never found another pumpkin balloon, but Claire made sure to find Brynn the real deal. Looking back, Brynn was sure that Claire stole that pumpkin from one of their neighbors, but that didn't matter. What was important was the hours the two spent together carving it up in preparation for Halloween.

Thinking about Claire triggered a deep sense of hatred in Brynn that was not her own. It was an implantation by the parasite - a wedge it drove between its converts and the outside world. The hatred only drove Brynn to deeper pits of despair and loneliness. She was nothing more than an object of sexual satisfaction now. She got her wish. Alex fucked her, bred her, worshipped her like a goddess, then cast her aside for a little variety. Now Bonnie was tasting the same fruit. It was a cold consolation that Brynn seemed to drive the horny shemale utterly mad with pleasure.

At least she's having fun.

As the sex dragged on, Brynn thought of her sister more and more. The hatred merged with the love and loneliness, pushing the girl's mind deeper and deeper. After a while, a new scheme formed in Brynn's miserable brain.

15 - Jackie

Jack didn't notice it at first. When he opened his eyes, he felt the rush of energy, and with it, confidence. He rose and stretched, arching his back. Even then, his brain didn't properly register the new weight and shifting of flesh.

It was only when he glanced down and saw nothing but a pale expanse of flesh that things clicked.

"Holy shit."

The voice was very soft. There wasn't a trace of the (mediocre) depth it once possessed. A quick brush of the throat confirmed this. No bump, just silky smooth skin wrapped around a delicate neck.

Panic arrived, but it felt almost vestigial. Jack cupped his new womanly swells and gasped at their enormous size. His tits were so big, they seemed to defy normal bodily proportions. They were sensitive too. He immediately regretted touching them as the momentary contact sent lightning bolts surging through the fleshy masses. That sexual current radiated through his whole body, concentrating in a wet, wanting void between his legs.

"No, this can't be happening!"

His objection was immediately met with a wicked little voice in his mind.

Is it really so bad?

Of course it was bad. Jack was a woman! He had huge tits and no adams apple and a hole where his dick and balls used to be. Every fiber of his being told him this was an emergency. Something precious had been stolen from him.

How would his friends react?

What friends?

How would his father react?

Who cares?

Jack tried to bring himself to crisis. This was really bad, right? His manhood was gone! That was the kind of thing boys freaked out about, but his reaction felt hollow. His body fell into the motions, pounding his heart and beading sweat, but under the surface he felt nothing.

Taking a breath, Jack assessed his situation. Nothing fundamentally changed since the last time he was awake. Sure, his dick and balls were gone, but that wasn't anything new. He lost his manhood when his scrotum split inside the lab. The boobs were certainly startling, but he had been dealing with them all day. They were just huge now. The voice was new, but it wasn't like he used to rock a deep voice or anything.

The thing that undercut Jack's panic the most was the feeling of his body. Previously, pain had dogged him. His chest itched and ached, his muscles twitched. Transformation was a bitch, but his metamorphosis had seemingly run its course. This was his new body here on out, and it felt amazing.

Energy coursed through Jack's veins. He stood straight for the first time in his life, keeping his chest out and shoulders back. This helped to further emphasize his massive rack, which should have been humiliating. However, the longer Jack stared at his breasts, the more thrilling they became. Huge tits were supposed to sag and deform, but Jack's were perfect globes tipped with fat, suckable cherry nipples. Most busty chicks complained about lower back pain, but Jack felt none.

Then there was Jack's pussy. It felt scandalous to even think of it as such. Gingerly, he crept his fingers down his belly, noticing the ripple of ab muscles as he did so, and then slipped down to his crotch. The whole world went white with that first fingering.

Jack's womanly essence surged to the forefront as he touched himself. This was so very wrong, but it felt right. He was a stranger in his own body, but that was okay, right? The life familiar to him had always proved cruel and unsatisfying. His body was unrecognizable, but that was more a blessing than a curse. It meant starting over and getting a second chance.

"Gah!"

Jack gushed. His pleasure splattered the bed sheets beneath him. It smelled sweet and lusty, further reinforcing his supreme femininity.

Finally, he let himself see his reflection in the full length mirror. It was dark, so he couldn't see all the details, but the figure reflected in the moonlight left him speechless. It was beyond perfect. The sexuality of it was almost obscene.

Jack understood immediately why his breasts, despite their size, felt so light and buoyant. His chest and back were broader, imbued with just enough muscle to easily support the new weight. Likewise, his abs had tightened and his thighs had thickened.

The girl in the mirror was the goddess of all blondes. Her pouting face encapsulated every cheerleading captain and school queen bee. Every centerfold and bombshell. Her sandy hair was longer, sending billowing curls down to the waist.

Jack posed for the mirror and giggled. Damn he was fine! He loved seeing his body jiggle and bounce with each movement.

"Maybe this isn't so bad..."

Suddenly, a large shape stirred under the covers behind Jack. He turned around in time to see a sharp, androgynous face framed with messy rainbow hair pop out of the blankets. There were tears of desperation in the big blue eyes.

"No, it's gotten bigger! I need to get it off before... ugh!"

Kit's squeaky fairy voice was gone, replaced with the scratchy half-depth like that of a teenage boy. The voice was paired with a face that, just like Bonnie's, was simultaneously handsome and beautiful. The parasite matured her delicate elfin features into something otherworldly. Was she a boy or a girl? It was an impossible question, and irrelevant too. She was gorgeous, and that was all that mattered to Jack.

"Get it off!"

Kit struggled with something under covers, accidentally causing the blankets to fall away. This gave Jack the second huge shock of the night.

When she was infected, Kit was wearing a loose, long sleeve sea foam button down and black slacks. Kit's arms, once delicate little twigs, had exploded in size, shredding the sleeves of her shirt. Jack traced the glistening biceps and triceps hungrily with his eyes. What would those big, beefy arms feel like wrapped around his waist? It was a yummy thought indeed.

Kit's entire upper body had thickened massively. Her chest and upper back were very broad, buffeted on either side by big, bulging round shoulders. Multiple buttons of her top had popped, revealing another fun surprise: cleavage. Gone was the flat chest. In its place were ballooning tits.

The biggest surprise, however, was hiding in the slacks. The pants were tight as tight could be, with each pant leg stretched to the limit around a monstrously thick thigh. It was obvious Kit's legs would soon erupt from the fabric just as her arms had. Surging between those beefy legs was an absurd bulge.

Kit groped at the bulge in a futile attempt to rip it off and then gasped in dismay as physical contact with her new organ overwhelmed her. Poor thing, she still didn't seem to grasp what was happening to her. Even her new muscles seemingly hadn't occurred to her yet.

I should feel guilty...

It was Jack's fault this happened - multiple times over, in fact. Had he locked Kit out of the laboratory, or refused to leave when she tried to rescue him, this never would have occurred. It was his parasite that changed Kit's sex. Despite all of these truths, he couldn't bring himself to feel bad about the situation.

It didn't help that Kit's new body was so damn intriguing. Those muscles were delicious. So sweaty and supple. Kit wasn't as big as Bonnie yet, but she seemed to have a lot of growth still ahead of her. Seeing the stringbean grow so big and burly moistened Jack's nether lips.

The bulge was what really captured Jack's imagination, however. God, it was already enormous! There was a wet mark where the head of the beast pressed into the fabric, hinting at untapped desire.

"Why won't it come off? Why does it feel that way?!"

Jack approached and gently brushed Kit on her thick, corded forearm. Immediately, the girl-turned-boy froze and stared at her wide eyed.

"I'm sorry, Kit. I know it's a big adjustment."

"Who the hell are you?" Kit's eyes immediately plunged to Jack's chest; her bulge did a little bounce.

"You don't recognize me?" Jack giggled. "You were my hero - you tried to be, at least."

Kit's right eye twitched.

"Jack?!"

The name spoken aloud didn't mesh right with Jack's new essence. It was so masculine and harsh. The more Jack felt his new body, the less he felt like a he at all. A final glimmer of panic stirred in his heart. He was a disgrace and a freak, forever unwelcome in his father's eyes. So what? Dad was an abusive prick. He neither loved nor liked Jack.

I'm going to be an abomination in his eyes no matter what. I might as well like who I am.

Jack never liked himself before, but this was a fresh start.

"It's Jackie now. Do you like how I look?"

"What happened to you?"

Jackie traced her fingers up Kit's luxuriously muscled arm and down her rippling torso before stopping right above Kit's new appendage.

"He certainly seems to like me."

Kit's bulge twitched frantically, as if begging to be touched.

"Don't look at it, it's disgusting! I need to get it removed before it does permanent damage."

She really doesn't recognize what's happened to her.

"You can't remove it, silly. It's a part of you."

"A part of me?!"

Jackie couldn't help but laugh at the bewildered look on Kit's face. God, she was so cute like this.

"Here, let me show you."

With agonizing slowness, Jackie pulled the waistband of Kit's pants down. The look of dawning horror on Kit's face was so unbelievably satisfying. Almost as satisfying as what popped out to greet Jackie.

Kit's cock was simply enormous. It was as pale as she was, and freakishly thick. The fleshy pink glans looked as big as a baseball. What was hiding beneath that monster was even more shocking. Kit's parasite had triggered the same freakish sex change Bonnie underwent, only Kit's new testicles were even larger. If her glans was a baseball, these things were softballs.

"No! Please God no! This can't be real. I'm a fucking guy?"

Jackie shook her head, feeling a sudden yearning to nurture her terrified friend.

"You aren't a man. Bonnie called it being a she-man, but I think that name is too clunky."

"Do you hear yourself? We need to go to the hospital and get this reversed!"

It was strange her words repeated back at her. Jackie finally understood where Bonnie was coming from. Her body was far past the point of return, and so was Kit's. They could never go back to their old selves, try as they might.

"This is how you are now," Jackie said. "If it makes you feel any better, I think you look hot."

Jackie couldn't believe herself. It was so scandalous to admit such a thing, yet she felt nothing. She still loved Bonnie, but when she thought of her partner dicking other women, the only emotion she could muster was mild arousal. Meanwhile, Kit seemed so raw and vulnerable. She was a strange contradiction as her girthy, bulging muscles quivered in terror. Jackie very much wanted to comfort her friend. It was a maternal impulse, and it sat so comfortably with her soul.

"Don't say that! I'm not a guy, do you understand? Men are violent, angry, abusive pigs!"

The contradiction deepened. Those massive balls were pumping her full of testosterone, which was in turn supercharging her short temper, turning her into the very thing she hated as she tried to fight it. What a pitiable thing to watch.

Jackie could have cowered in fear like she used to do when someone bigger and stronger than her was angry. Kit's new physique could easily allow her to hurt or kill the girl. Jackie, however, was tired of running. She had learned a thing or two from her time with Bonnie, and she knew exactly how to stop this temper tantrum. She reached out and firmly grasped Kit's new cock at the base. The twitching beast was so thick that Jackie couldn't wrap her fingers all the way around it.

Immediately, Kit went still and silent. She stared at Jackie and finally registered what she saw. Her eyes soaked in the blonde's heaving bosom and unnatural curves.

With her other hand, Jack cupped Kit's balls. God, they were so heavy! The twin organs pulsated with ripe, masculine power.

For a gal who hates men, her body sure embraced becoming one.

The shame and horror melted off of Kit, leaving only a single-minded drive to breed. For the first time in her life, Jackie held complete control over another human being. It didn't matter if Kit could easily snap her neck. Right then and there, Jackie could tell her friend to jump off a cliff and the command would be obeyed. Bonnie had been right about so many things, and this was one of them. There was power in beauty. That power exceeded huge muscles or impressive athletics.

Jackie pulled Kit close, leading the transformed dick girl right to her glistening new pussy. For a brief moment, Kit tried to put up one final fight.

"This isn't right."

Jackie wrapped her arms around Kit's muscled lower back and pulled. The massive glands pounded against her womanhood. The sensation proved too much for poor Kit. When she thrust, it was like taking a bite from the forbidden fruit.

Kit entered Jackie and exited the sisterhood of womankind forever. Meanwhile, Jackie joined its ranks. After a few seconds, they both forgot their old selves entirely.

16 - The Trap

The call came in just after three in the morning. Claire considered sending it straight to voicemail and going back to bed. After all, she needed her sleep if she wanted to continue her search for Brynn and Alex in the morning. Then she saw the caller ID and bolted out of bed.

"Brynn?!"

"Claire, thank god you picked up. I need your help!"

Brynn started to babble rapidly on the other side of the phone. Just hearing her voice brought so much relief to Claire's heart.

"Slow down, sis. First off, tell me what happened."

"The guys from before came to your apartment and took Alex and I," Brynn sobbed pathetically. "They beat Alex so badly. He needs to go to the hospital, but they won't let either of us out of the house."

Cold rage settled over Claire. These bastards had messed with her family and friends for the last time. She wanted revenge, and she would have it. First things first, however, she needed to get Brynn out of there.

"Take a breath, Brynn. If you know it, I need you to tell me where you are."

To Claire's surprise, Brynn had an address. The place wasn't far off, either. It sat right on the edge of the nearby college, which was hardly a surprise. Claire managed to get the near hysterical Brynn calm enough to work out a plan. Brynn would navigate to the basement and unlock the sliding door. They would sneak off into the night.

"What about Alex?"

There was no good answer. If he was badly beaten, he would only slow them down. As cold as it was to say, he couldn't come with them.

"Don't worry, Brynn. We're calling 911 as soon as we're safe. The cops and paramedics are going to swarm that house. They'll save him."

"Okay..."

"You're going to be safe, Sis. I'm coming for you."

Claire could practically hear the smile on the other end of the line.

"Thanks, Claire. I love you."

"I love you."

Claire immediately channeled her juvenile delinquent past. She changed into all black, tied her hair back into a tight, low bun, and grabbed a pair of gloves she bought back when she thought she was going to have a deck garden. Next, she rummaged through her kitchen for an arsenal of weapons, settling on the long, thin knife she used to slice fruit. To this, she added a hammer from her (mostly neglected) tool kit and Alex's pepper spray.

The house was dead when Claire arrived. The world was trapped in a pre-dawn stillness and mist clung to the ground. Like a thief in the night, Claire darted down around the back of the townhouse block, moving along the woodline. Something darted out of the woodline as she moved, and it took all her strength not to scream. Her nerves settled and she watched the iguana waddle off.

Keep it together, Claire.

Brynn appeared like a ghost, pale and beautiful, when Claire knocked on the sliding door. She seemed prettier than ever. Claire expected to see bloodshot eyes and tear stained cheeks, but her sister somehow found her composure in the time it took Claire to arrive.

The two sisters hugged for a solid minute once Claire was inside. It was the homecoming Claire always wanted. For the first time in a long time, there was zero distance between them.

"You're safe now, Sis."

Brynn squeezed her back.

"I know."

Claire took Brynn by the wrist and turned to leave, but to her horror, there was a tall, hulking figure blocking her exit. It took a moment for Claire's eyes to adjust, but when they did, her jaw dropped.

"Alex?!"

In the hours they had been apart, Alex had grown nearly a foot taller and a hundred pounds heavier. His gigantic, mutated muscles gleamed in the dim light as if he were cast in iron. His penis, once a manageable size, now extended over a foot from his body. It twitched hungrilly.

"Damn, Claire, you're looking good! Black's always been a good color on you."

"Brynn, you said they beat him up."

"They must have infected him. Oh God."

Alex shot a strange look at Claire's sister, then refocused on her. His beefy hand curled around his cock.

"I"ve been thinking of you a lot. That redhead, Kaylee, she's a good substitute, but I've been craving the real deal, and now I get it."

"Alex, you need help. Let us go, and we'll get doctors here as fast as possible."

"Help? That's ridiculous. I've never felt better! Look at me, Claire. My body's gotten so big and powerful. I feel so young and virile. It's like I'm a college kid again. Don't you want a taste of that?"

"I can't think of anything I want less, now let us go!"

Alex smirked, "What are you gonna do?"

Claire pulled the knife and watched the smile fade from her boyfriend's face. She had crushed the smug grin plenty of times before, but this was the first time it didn't make her feel good about herself. The parasite twisted Alex into the worst version of himself, leaving nothing but a womanizing, aggressive freak.

"Step aside."

Alex looked from the knife, to Brynn, to Claire. Had Claire been paying attention, she would have noticed his eyes settle to a point just over her shoulder, but she was too focused on making her threat seem real. The last thing she wanted to do was stab her boyfriend, but she needed him to think death was imminent.

"No," Alex took a step, forcing Claire to retreat.

"I'm serious! Don't make me hurt you."

Alex took another step. Claire reluctantly matched his advance with a retreat, but this time took a half hearted swipe at him with the knife. The way he dodged it startled her. Alex hadn't been in terrible shape, but his new reflexes were no joke.

"Stop it, Alex. You don't want to do this."

"I think I do!"

Another step forward. Claire realized it was now or never and tried to lunge with the knife. Before she could, however, a massive hand grabbed her by the wrist and wrenched her arm back. Whoever it was, their strength was ungodly. All it took was a simple squeeze to disarm Claire. The knife clattered to the floor, and with it, Claire's best chance of escape.

Claire wasn't the type to go down without a fight, no matter how hopeless the odds were. She reeled around and punched at her attacker's chest as hard as she could. It was only when her fist sank into the soft, pillowy flesh of a breast that the unreality of her situation dawned on her.

The attacker was huge, standing as tall as Alex and possessing even more muscle. The biceps, triceps, shoulders, quads, and calves were all so supple and round. The skin was pale and soft. It was a physique as gorgeous as it was dangerous. Claire gently squeezed the massive, fleshy globe on the person's chest to confirm it was real. It was a boob, and it had an equally remarkable twin. Claire finally looked up into the face of her captor and gasped.

Another person might have struggled to recognize Bonnie Huntsman, but not Claire. Despite the extraordinary changes to her best friend's body and face, Claire knew it was her friend immediately, and that recognition brought deeper horror.

"I've lost my mind."

"Not yet," Bonnie spoke, her voice sounding startlingly deep, as she pulled Claire close. "That's for later."

Claire felt the heat of something that had no business being on a woman's body. The turgid member pulsed against her belly.

"Hey, who said you got to have her first?"

"She's my best friend."

"And she's my girlfriend, so back off!"

Alex rushed Bonnie, shoving her hard. In the confrontation, Claire was thrown to the ground. She knew she needed to flee, but the scene was so bewildering that she was momentarily paralyzed.

The two hunks began to fight. Claire watched her easy going boyfriend and her womanly best friend lock burly arms like two bulls. Their angry, straining grunts made it all seem like some kind of primal mating ritual. Claire could recognize her beautiful, graceful friend in the towering hermaphrodite, but her brain couldn't reconcile that connection.

It suddenly occurred to Claire that this was the only opening she and Brynn were going to get and tried to scramble to her feet.

"Come on, Brynn. Let's scram before it's too late."

A moment later, Claire screamed in agony as a heel stomped down on her ankle. She looked up and saw through the tears a familiar face twisted in rage and hatred. Who knew Brynn possessed such malice? She almost seemed possessed.

"Why?!" Claire tried to stand and immediately crumpled.

"What do you mean, why? Why do you think I called you here? So you can become one of us, obviously."

Brynn's voice was cold and snide. Gone was the terrified little victim act. She stood tall and proud, showing off her impossible figure like some goddess from myth. As soon as she rested her long, delicate fingers on each combatment, both Alex and Bonnie went still. Her beauty was enough to entrance both of them fully.

"Why would you do that? Haven't you been taking your medicine? I thought you were getting better."

"Better? I felt like shit, not that you would care. You were too busy snatching the love of my life away from me."

"I don't understand."

"Of course you don't. How could you?"

Brynn gripped Bonnie around the base of her unholy new man part, and then did the same to Alex. Both hunks trembled in her grasp.

"Stop this silly fighting, boys," Brynn gave Bonnie a little stroke that nearly sent the mutated man-woman over the edge. "I bet you never thought someone would say that to you, Bonnie."

"Fuh-uh-fuck! You really know how to stroke it, don't you?"

Claire couldn't get over Bonnie's new voice. It wasn't male, per se, but right on the line.

"Alex, you need to back down," Instead of one hard stroke, Brynn gently rubbed her hand up and down the freakish length of the man's cock.

"What? Why should I listen to you?"

Despite the horror of the situation, Claire couldn't help but feel a faint blush of pride at what happened next. She was so used to timid, meek Brynn. This new version was anything but. The girl grabbed Alex's swollen testicles and squeezed them hard enough to make his knees weak.

"Because I'm your girlfriend, soon to be wife, and I'm fucking tired of watching you have sex with other girls. I gave you this gift, don't forget it!" Brynn returned to Alex's cock with gentle, loving strokes. "Besides, you've gotten to bang Claire plenty already. It's time for her best friend to have a chance."

"Hold onto her, Alex. She's a keeper," Bonnie huffed, her new cock still throbbing in Brynn's hand.

"Don't worry, Claire. I think you're going to be more than satisfied with your new boyfriend. Bonnie is one hell of a wild ride. I know that from experience!"

The implications were nauseating.

"Why are you doing this to me, Brynn? Why do you hate me? I know we haven't always seen eye-to-eye, but I've always loved you."

"I hate you because the parasite commands me to. You're not one of us, so that makes you my enemy," Brynn's eyes turned misty. "You also stood between me and my man. I didn't want to share, but I guess I don't have a choice anymore."

The shocking reveals kept piling up. In an instant, dozens of innocent little moments were recontextualized in Claire's mind as she realized her sister's smoldering obsession.

"Got it, so this is punishment for taking 'your man'."

"No, I did this because my man isn't enough. I've gotten everything I ever wanted, and I still feel so alone. I've been lonely for so much of my life, and I'm tired of it. You were the one person in our house that made life feel fun, and then you left for college, and you never came back. I miss my sister."

"You hate me."

"I don't want to. That's why you have to be one of us. Then we can finally be together again. It'll be so nice, Claire. We'll be sisters again, and closer than ever!"

The light in Brynn's eyes was that of a fanatical religious convert. There was no reaching her, and no chance of escape. Even if Claire managed to stumble out the door, she wouldn't make it far.

"This is a very touching family reunion," Bonnie said as she advanced on Claire. "But Rex is getting hungry. It's high time Claire and I consummate our relationship."

"Rex?! You named your penis?"

It was the kind of absurdity Claire and Bonnie might have giggled about under different circumstances. Bonnie was always coming up with quirky nicknames for things she worked with, but there was nothing funny about this one.

"He wasn't my penis when I named him."

Bonnie climbed on top of Claire and began fumbling with her waistband. The parasite seemingly stripped all subtly and foreplay from the woman's mind, leaving nothing but a single-minded drive to breed.

There had been a time when Claire slutted it up across campus. She had laid with dozens of guys, plus a few girls, and recognized the heat and smell of Bonnie's body immediately. Sweaty skin drenched in pheromones worked magic on the brain. Gears turned beneath the woman's terror. Bonnie's new body was built to turn on every light inside Claire's brain.

No, this is Bonnie. She's not some dude to fuck. She's your best friend.

Claire's body didn't seem to care. Against her will, her pussy moistened and her nipples grew erect before Bonnie even took her clothes off.

As the body gave way, the mind panicked. Claire realized that infection was imminent. After this, there was no one left to pump the brakes. The infection would spread far and wide, holding her and Brynn in its clutches.

"Bonnie, you have to fight this! Let me go and I'll get you help, I swear!"

"Ha, you sound exactly like Jack."

Bonnie twirled a loose strand of Claire's ginger hair with an index finger more than double the size it had been.

"Bonnie, this isn't you!"

"People change, Claire. Some of them join with weird amazonian penis worms and start seeing their best friend of a decade in a new light."

Bonnie pawed Claire's chest like a horny frat boy with one hand while exploring the inside of Claire's waistband with the other. The aggression was startling. The changes to Bonnie's body were shocking to behold, but her behavior made them substantive. The woman(?) had transformed down to her bones.

"They notice how big their bestie's tits are, and how soft and sweet her face is. They notice the cute freckles and round little nose."

"Bonnie, please don't do this!"

The sound of shredding fabric echoed through the room like thunder. Bonnie tore Claire's black leggings like they were made of tissue paper. Cool air wafted over Claire's crotch, popping goosebumps on the pale skin.

"Come on, Claire. I know how many guys you've been with. Aren't you the slightest bit curious what it would be like between us?"

"No!" Even as Claire said so, a little voice whispered in the back of her mind.

Can you think of anyone you know better? You always thought she was cute, and now she's more appealing than ever. After all, you love a good set of muscles.

Claire tried to fight the thoughts off more for her own sense of dignity rather than for any practical reason. The situation was hopeless, but she couldn't let herself surrender. Not yet.

Something hot pressed against the skin just above Claire's pussy. A dribble of precum oozed down onto her clit. From the feeling of it, Bonnie's member seemed positively enormous. Claire's panic channeled into one last ditch effort to reason with her fallen friend.

"Bonnie, let me escape and we can find a cure! We can stop this thing."

The look in Bonnie's eyes terrified Claire. The ferocity was like anything Claire had seen before. This was not the graceful, easygoing Bonnie she used to know. This was a single-minded beast.

"I don't want to stop it, I want to spread it."

"You don't mean that, Bonnie."

Bonnie pinned Claire's wrists to the bed with terrifying strength. With her new size, she radiated heat like a furnace, causing Claire's exposed skin to bead with sweat.

"Claire, I love you," Bonnie's voice was hard as steel, yet soft as a fuzzy blanket. "Now shut the fuck up and let this happen."

She loves me. Maybe that isn't so bad.

Then Bonnie thrust her hips and the two best friends became one.

17 - Maelstrom

Even for someone as experienced as Claire, the pain was unbearable. Bonnie moved with surprising tenderness, easing her manhood into Claire's birth canal, but with something that big, pain was inevitable. Each new inch stretched Claire closer to her limits. She'd taken her share of big dicks in her life, but none quite so large, and none from someone so familiar.

Bonnie tried to move slowly for Claire's sake, but the man in her quickly took control. Halfway in, she lost it and thrust with her mighty hips. In one agonizing instant, she surged into Claire fully. A moment later, her balls slapped against Claire's ass.

Balls! She has balls?! Make it make sense...

"Sorry," Bonnie muttered in Claire's ear.

It was oddly endearing that a hint of Bonnie's sweetness remained in the face of so much mutation.

For several seconds, Bonnie lay on top of Claire, seeming to relish the moment. As horrified as Claire was, she had to admit that there was something entrancing about their connection. Their bodies were syncing up. Bonnie's scent filled Claire's nose. It was dark and musky, just like a guy's, but there was an unmistakable buttery sweetness as well. Bonnie's skin was as soft as silk. The muscles underneath were as hard as steel. Claire's brain twisted itself in pretzels to connect that raw strength with the soft, feminine woman she remembered.

Bonnie gazed into Claire's eyes. So much was contained in that simple look. Ten years of friendship built a well of intimacy. There wasn't a single person on earth who knew Claire quite as well. What had once been innocent and platonic now turned on its head.

The infection repulsed Claire. It turned her mousy sister into a mean spirited bimbo and her boyfriend into a predatory meathead. It was a nasty, corrupting thing. Bonnie was the clearest evidence of this. If it could turn such a poised and beautiful woman into this horny sexual beast, it could do anything.

Even so, Claire couldn't help but blush as she stared into her best friend's eyes. Bonnie's new manhood twitched frantically inside of her. The feeling of being wanted, especially by someone so dear, was addicting. If Claire had to be infected, was there any better person to do the deed?

Bonnie kissed Claire. At first, it was little more than a peck, but things heated up quickly. Their lips crushed against each other as spit flowed freely. Bonnie's tongue, like every other part of her, was bigger and stronger. It weaved between Claire's teeth and started exploring every inch of her mouth.

The thrusting began in earnest. For the first minute, it hurt like sin. Bonnie's cock was tremendous and Claire's pussy was tight. Besides Alex, Claire hadn't slept with anyone in nearly six months and her body was out of practice. Each thrust brought Claire closer to her breaking point. Bonnie was in heaven.

Eventually, Claire's body wrapped around the situation. It finally recognized the experience as sex and Bonnie as a male partner. The pain faded, giving way to raw pressure. In the void, Claire's brain was left alone to struggle with her new reality.

Bonnie has a dick. She's a guy now! No, not quite a guy...

Their breasts mashed together as they fucked, reminding Claire that Bonnie retained much of her old femininity. This only made it harder for Claire to comprehend her best friend's transformation. It was still the same Bonnie she knew and loved, but now with one hundred and fifty pounds of extra muscle and an insatiable lust for women.

Bonnie, what have you done to yourself? You've damned both of us...

Claire's resistance quickly lost steam. Sure, she didn't want to be infected in an abstract sense, but it was hard to panic when there were so many physical sensations crashing down on her. Each passing moment drew her closer to Bonnie in a way she never anticipated.

Their hands twined together. It was such an intimate little thing to do during sex; the kind of thing a husband and wife might do before conceiving a child. Bonnie's ragged groans dripped with worship. Claire matched them with a song of dueling pleasure and pain. Each thrust of Bonnie's cock stitched their souls closer together.

"I'm sorry, Claire. I know you didn't want this, but I need it. I need you. Ugh, you don't understand what it's like."

The boiling conflict in Bonnie's darkened voice was something to behold. So much passion and intensity laced it, turning every word into a spark of electricity in Claire's mind. Something inside the woman broke. She resigned herself to her fate.

"It's okay, Bonnie," Claire kissed her. "I love you."

Bonnie lost it. She roared and thrust herself to the hilt. Jets of hot, syrupy spunk slathered Claire's insides. Her fate was sealed.

The feeling of Bonnie's muscles twitching, her big lungs heaving, her whole massive body trembling with lust induced mind numbing pleasure in Claire. All of this passion and need was devoted to her.

That's it, Bon Bon, let it all out.

Claire wanted to bask in the afterglow. This new relationship was so strange, yet so exciting. Terror bit at the edges of her consciousness, but the blossoming love in her heart kept it at bay.

Unfortunately, an argument was breaking out. Apparently, Alex demanded his share. Bonnie didn't want to budge, and it looked like another mating fight between the two bucks was inevitable. Once more, Brynn stepped in to quell things.

"Stop fighting, you two! Remember, we're all part of the same tribe. Bonnie, I think Jack's awake. I heard noises coming from his room. Alex... just make it quick."

Please don't leave me, Bonnie.

"I'm sorry, Claire," Bonnie whispered in her ear. "Just remember, you're mine."

It was the hottest thing anyone had ever said to Claire, and it was followed by the biggest disappointment. Bonnie pulled out, leaving a miserable void in the woman's center.

Moments later, two enormous arms lifted Claire. The world spun and warped as she was carried up the stairs to a bedroom on the main floor of the house. There were blackout curtains on the window that blocked out what little pre-dawn light there was. In the darkness, Alex found her.

Unlike Bonnie, he didn't even try to be gentle. He simply took his fill. Bonnie had undergone a whole damn sex change, and even her transformation didn't compare to Alex's. Not only was Claire's former boyfriend now built like the hulk, but he also shared the monster's manners.

Despite dating for years, there were no intimate words exchanged between them. Alex treated Claire like a checkbox to mark. His thrusts were mechanical and harsh, designed to bring him to climax as fast as possible.

You can keep this asshole, Brynn.

The whole experience wouldn't have been so bad in isolation. After all, Claire didn't have anything to lose anymore. Bonnie's infection was blossoming inside of her with each passing second. Alex's desire to use her stung, but it also meant that the ordeal would be over soon enough.

Unfortunately, Brynn kept getting in the way. She wouldn't shut the hell up.

"Enjoy it while it lasts, Claire. This is the last time you get to have him."

Poor me.

Brynn kept trying to put hands on Alex, but he kept pushing her away. Eventually, she settled on bugging Claire. She parked herself right over Claire's face and started babbling incessantly. What would have been annoying became unbearable due to Brynn's huge tits.

"Ugh, I can't even stand to look at you right now."

Brynn's right breast mounded over Claire's face, temporarily blocking her air flow. Her sister smelled very sweaty and a little sweet like honey. It wouldn't have been so bad getting motorboated by a busty broad if that broad hadn't been her sister.

"Tell me, Claire, are you having fun?"

"Mmmm, ummf, mmmm ugh."

"Eek! That tickles!" Brynn giggled, stumbling backwards and throwing her arms over her chest.

Jesus, they're big.

Claire wasn't turned on in the slightest by her sister, but she had to admit that the parasite had done a body good.

"Take this, you little ginger slut!" Alex groaned.

In came Claire's second dose. Alex was as virile as Bonnie, and quite a bit rougher in delivering his payload. The stuff slathered every inch of Claire's pussy from front to back.

He used to be so gentle.

"Ugh, are you done?" Brynn stomped, causing her boobs to jiggle violently.

"Will you get off my back?" Alex snapped. "We're not fucking dating, Jesus."

Alex stomped off, presumably to find another girl to fuck, leaving Brynn to her tears and shock. Claire's heart ached for the girl. Who knew she had such strong feelings, and for Alex of all people. What a waste.

Claire wanted to comfort her sister, despite everything the girl had done, but by then the parasite was starting to take effect. An intense heat flushed her body, especially around her crotch, chest, and face. Paired with the fever was dizziness that made it impossible for Claire to walk or even stand.

"I bet you're happy, aren't you?" Brynn snapped.

"No."

Brynn's rage melted away, leaving a scared, miserable girl. Her sobs were unbearable to listen to.

Before Brynn could leave, Shawn and his pervy friend from the coffee shop found them. They took Claire and her sister together.

Shawn took Claire first. This wasn't a matter of desire, but instead revenge. Claire stood in the way of his grand plans, so she had to suffer. Meanwhile, poor Brynn resigned herself to his friend. The two men forced the sisters together and took them both from behind. Apparently, the intention was to get Claire and Brynn to make out. There was no universe where that was happening.

"I'm so sorry," Brynn sobbed. "I shouldn't have done this."

Claire held her sister. The girl's tits were enormous, and oddly comforting against her own burning chest. They were so soft and pillowy.

Something flipped in Claire's brain as Shawn pounded her. He wanted the satisfaction of breaking his boss. With each thrust, he blathered about turning Claire into a horny slut and breaking her innocence. Now that the deed was done and Claire was infected, it all felt very tiresome. With nothing left to lose, she decided to have a little fun.

Claire twisted around with lightning quickness while still impaled on Shawn's cock. He stiffened, clearly expecting Claire to resist.

Oh buddy, are you in for a surprise!

Claire wrapped her legs around the young man's waist and dug her nails into his back hard enough to draw blood.

"Do you have any idea how many guys I've been with?" She whispered in his ear. "You're not special. Do your worst."

Shawn thrust harder and harder, but Claire mocked him each time. With his parasite enhanced muscles, the boy could easily crush Claire's skull with his hands, but strength no longer mattered. The power dynamic had shifted. She was in control.

Claire remembered Shawn from his interview. Before the parasite, he had been a polite, awkward nerd - the type she used to hunt for sport back in college. Deep down, that dork was still hiding under all the muscle and bravado. All it took was a little prodding for him to lose control completely. Gone were any thoughts of revenge. Claire was his redheaded goddess, and he was nothing but a lowly devotee.

The third dose came quickly. It was smaller than either Bonnie or Alex's. Shawn was an older model, apparently. The newer parasites made bigger, more virile males.

Shawn dropped Claire and stumbled to the corner to catch his breath. Taking the opportunity, Claire shot to her feet and appraised the situation. Shawn's friend was lodged in Brynn and having the time of his life. Brynn was not on the same page. Her tears were like the blood of her dying dreams.

If there's nothing to lose, I might as well use my slutty self for some good.

Claire grabbed Brynn and yanked her forward. She came off of the boy with an audible pop! The immediate reaction from Shawn's friend was rage. His face contorted in anger so violently that he almost didn't look human. Claire braced herself for getting hit and tried to remember her plans.

"I thought you liked redheads, big boy. Don't you want to be with a real woman?"

For emphasis, Claire grabbed his bobbing cock and pulled him close to her. Rage transmuted to lust in an instant. He impaled Claire and pounded her so hard her teeth chattered.

"Go!" Claire hissed to a shocked Brynn.

It took the girl a moment, but she finally understood what Claire was affording her and scuttled off.

Just one more guy, Claire. Then you can escape.

Shawn's friend wouldn't shut up as he fucked Claire. He kept calling her a goddess and 'the perfect woman'. As sideways as the situation was, it flattered Claire more than she wanted to admit.

The boy didn't last long. After another minute, he splashed her insides with a fresh load. Halfway through, he dropped Claire to the floor and slathered her in the last few pumps. It wasn't anything new to Claire, but damn did she hate it.

As her mate collapsed in a heaving mess, Claire saw her opportunity to escape. If she could get back down to the basement, she could slip into the night unnoticed and get to a hospital. The sooner she could get on antiparasitics, the less changes her mind and body had to go through.

That hope was dashed immediately. Two powerful arms wrapped around Claire, and she heard the voices of Brett and Zander. At the same time, Shawn and his friend regrouped. So much for escape.

They took turns on her for the next hour. Claire's consciousness dulled until became nothing but sensation. Endless pounding and wobbling. The bleach scent of semen mingled with the darker notes of sweat and musk. Her body burned and ached. With each passing second, it felt less familiar.

After a while, they left. Sleep found Claire for an indeterminate number of hours. When she awoke, there was a border of white light around the blackout curtains. She felt someone climb onto the bed. Judging by the way the frame squeaked, the person was enormous.

"Jesus, you're really fucking hot."

The voice was strange. It sounded like it was just starting to turn deep. Bonnie's voice had the same quality, but this was not Bonnie.

A heavy, exorbitantly thick and muscular body climbed on top of Claire. Two massive, bulging arms wrapped around her torso. Just like Bonnie, whoever this was, they smelled odd, as if a man's scent and a woman's were shoved together.

"I'm so sorry. I know I shouldn't, but your body looks so good. I swear, this thing is controlling me," the person sounded on the verge of tears.

Claire got only a brief warning of what was to come. The gigantic glans pressed against her opening like a hot iron. Then everything went white with pain.

"Oh my fucking god! Ugh, it's so intense! I need it! I'm so sorry... but I need it!"

The two sweaty bodies, one massive and muscular, the other dainty and feminine, rubbed up against each other. It was then that Claire noticed the soft swells on the stranger's chest.

Boobs? They must be like Bonnie. Jesus, what a nightmare.

"I'm sorry! Oh God, I'm sooooo sorry!" The person sobbed.

Of all the people to fuck Claire that night, at least this one had the kindness to apologize. Claire pitied her new partner. Whoever he, or she, was, they clearly felt very broken up about what they were doing. Claire wrapped her legs around their waist and gently rubbed their back. Goddamn, those muscles were incredible. Claire loved a good set of muscles when the owner was a decent person.

"It's okay, honey. Let it out."

The stranger lost it. They pounded Claire like a wild animal and then erupted with the force of a firehose. Claire got an apology for each squirt.

In the aftermath, the figure tried to get up, but Claire held them back. She felt lonely and tired. Sure, the person was a stranger, but sex had a way of connecting two people. Claire wanted to be held, and the person reluctantly obliged.

More sleep. Being held in the arms of a gender ambiguous giant finally gave Claire the comfort to get a solid block. Perhaps there were other men in the dark hours that followed. It was hard to differentiate dreams from waking at that point. Claire's fever worsened and the pain in her body intensified such that escape was impossible and sleep was the only relief. There were no dreams in her deep, but troubled sleep. Just vague imaginings.

18 - A New Breed

"Wakey wakey sleepyhead."

Claire slowly opened her eyes and beheld Brynn's beautiful face. She winced, remembering the venom from the night prior, and prepared for the worse, but Brynn just beamed with a dopey smile.

"Do you still hate me?"

"Of course not! You're one of us now. Speaking of, let's see that new body, sis," Brynn grabbed the comforter covering Claire and ripped it down.

Claire didn't know what to expect. The parasite gave Brynn big tits and stunning curves, but Claire had been part of the D-Cup club for over a decade. She half expected to see the same old body she was used to. Hoo boy, was she in for a surprise.

Her tits were bigger - huge, in fact. They surged out of her chest like the effects of a 3D amusement park attraction. Despite their size and fullness, they felt oddly light. Claire sat up and bounced a little to see what her new girls were capable of. They jiggled less violently than she expected, with movements that were compact and cute. She could feel her back muscles contracting to keep the puppies tight and perky.

The boobs were the smallest shock. Claire half expected to see a dick sticking out between her legs. It happened to someone as beautiful and feminine as Bonnie. Certainly Claire, with her temper and tomboyish nature, would be a perfect candidate for a partial sex change. Luckily, her vagina was intact. The rest of her body, however, was alien.

Claire remembered a short, squat body. Years of neglect plumped her body. She liked to think that most of the new fat went to all the right places, but plenty of it went elsewhere too. Now, the fat was gone. Claire sported an eight pack on her tummy. Her thighs were thick and muscled like those of an olympian. The legs they belonged to felt much too long. Her shoulders and biceps were bigger too. She wasn't hulking or mannish, just very athletic.

"Holy hell, you look like an amazon, sis!"

"No kidding," Claire stood and noticed that the floor seemed farther away than she remembered. "This is strange."

Things quickly got even stranger. As Claire's drowsiness faded, she realized that she and her sister were not alone in the bedroom, and the other occupants were hardly quiet.

In the corner, two people were having sex. Claire at first clocked them as a man and a woman, but quickly reassessed. A penis was certainly going in a vagina, but beyond that, the picture seemed more complicated.

The 'male' was simply enormous. They weren't quite as tall as Bonnie or Alex, but they made up for the lesser height with thickness. Huge, burly biceps and shoulders and a rippling back. Then there were other, more conflicting qualities. Their skin was too soft, and there wasn't a trace of hair on it. For hair, they had a short rainbow-dyed pixie cut that Claire couldn't imagine a musclebound jock choosing. They possessed a chiseled jawline that clashed with their intensely delicate facial features. Finally, and most odd of all, were the boobs. They were bigger than Claire's.

The other was less strange on paper. She was an exceptionally busty blonde with long, wavy hair that bounced up and down with each thrust of her partner's cock. She was taller than Claire expected a girl to be, standing nearly six feet, but she was otherwise normal, or at least conventional. The strangeness came from the familiarity. There was something about the lilt of her voice, the color of her hair, and the splatter of freckles on her face that seemed oddly familiar.

"Oh fuck, I'm never going to get used to this!" The other's voice was familiar as well.

Claire watched the girly male lose control. There was something mesmerizing about those huge, twitchy muscles. Each thrust seemed so mechanical and raw. They came like a primal force was ripping the spunk from their cock.

When the couple finished, the 'male' slumped against the wall in a heap and cradled their head while the girl bounced over to bed. As she ran, she nearly slapped herself in the face with her own boobs.

"Wow, Jackie, you really fried her brain!" Brynn gushed.

The blonde fell on her belly. Her enormous tits billowed out like expanding pools of batter underneath her. Claire knew this chick from somewhere.

Jackie, where do I know a Jackie from?

"Be nice. Kit's whole world just got turned upside down. It's going to take time for her to adjust."

Rainbow hair shook their head and trembled, "I can't stop!"

Jackie looked directly at Claire and smiled, "You turned out amazing. Bonnie's going to be so happy."

Suddenly, it clicked. Claire knew exactly who 'Jackie' was, but the answer raised more questions. Apparently, Bonnie wasn't the only sex change of the bunch.

Claire remembered her best friend and felt a puzzling witch's brew of emotions. On one hand, Bonnie essentially raped her. The night prior had been the most traumatizing Claire ever experienced, but in the light of day, she couldn't bring herself to care. When she thought of Bonnie, she felt a spark of excitement, and a deeper emotion only reserved for lovers.

The train of thought seemed to summon the woman herself. The door to the bedroom opened and in walked Bonnie. She had to duck through the doorway because she was so tall. She was dressed in a supersized version of her usual attire: a professional white button-up blouse, black jacket, and slacks. The outfit was snug, showing off her bulging muscles underneath, but by some miracle, it fit her massive size. As soon as Claire saw her best friend, she felt hot all over.

Bonnie was joined by two others. One Claire recognized as the clerk who fitted Brynn days earlier. She was several cup sizes bigger than when Claire last saw her, with her voluptuous new body packed into an ill-fitting top and shorts so short they might as well have been panties.

The other one Claire knew from Bonnie's work. She was a trans girl named Heidi. Her body wasn't quite as far along as the clerk, but her small HRT induced breasts already seemed plumper than Claire remembered. Both women were red in the face and glassy in the eyes.

As soon as Bonnie saw Claire, she lost it. Her big, burly arms were around her best friend in an instant. Then came the kisses. Long, heavy, passionate sucks and licks. Claire resisted out of instinct for just a moment. It was the last dying gasp of her old self. Then she gave in completely. This muscular superbeing seemed specially designed to light up every neuron in Claire's brain.

Bonnie pulled away and carefully undid the buttons of her blouse, revealing her delicious cleavage as she did so. For all her muscle and manhood, she was still the hottest woman Claire knew.

"I have to be careful with this blouse. You have no idea how hard it was to get one that fit."

Claire said nothing. She was too busy worshipping. Ten years of love and friendship turned to lust instantly.

Once Bonnie's clothes were removed, her most striking feature came out to play. She called him 'Rex' and treated him more like a pet than a penis. Claire still couldn't understand how it ended up there. The last she saw, Brynn's worms showed no interest in women, Bonnie included. These were questions for later. They both had more primal needs.

Bonnie fucked Claire's brains out right in front of Brynn and the others. Each thrust brought the two of them closer. Claire groped wildly with her hands, trying to learn as much of Bonnie's new body as she could. Last night had been a whirlwind of terror and dismay. Claire was so afraid that she couldn't appreciate the moment. The second time around, she wanted to savor things. She groped Bonnie's huge tits and rubbed her rippling biceps. The big, meaty back and waspish waist. It was all so glorious.

The climax happened quicker than Claire would have liked. Bonnie was like a horny teenage boy, still trying to get a hang of her new male parts. It was adorable listening to her lose control and groan wildly. Baby batter splattered Claire's insides and a new thought graced her mind, one that was particularly infectious.

Could she get me pregnant?

Claire didn't see why not. Bonnie had balls, for god's sake! Unless she was shooting blanks, she probably had the capacity to father a child. Just the thought of it made Claire cum too.

The afterglow was glorious and silent. For the better part of fifteen minutes, the two of them nuzzled together on the bed. Bonnie remained lodged inside of Claire, creating a sense of shared intimacy that couldn't be beat. Eventually, they started talking. By then, Bonnie registered in Claire's mind not as a friend, but as her lover. Her one and only.

"God, you're even hotter than I thought you would be. Plus, you're so tall!" Bonnie gently caressed Claire's plump, toned arms. "You even gained some muscle! I wonder what strain of the parasite gave you that. I'll have to take a sample later."

"Speaking of muscles, care to explain how my girl best friend turned into my boyfriend?"

Bonnie flashed a sheepish grin.

"I may have accidentally tricked one of the worms into thinking I was a male host."

"I told you to be careful!"

"I know. In fairness, I never in a million years thought it would turn me into a guy. It's preposterous," Bonnie suddenly kissed Claire's neck, sending shivers up the woman's spine. "Not that I'm complaining about the results."

Suddenly, the two of them heard moaning from the corner of the room. They both looked over and saw that the muscular girl/boy Jackie called Kit was now buried inside the busty clerk, who moaned like a whore.

"I'm sorry, it'll be over soon," Kit sobbed. "God, why can't I control myself?"

"Will you shut up and just fuck me?" The clerk snapped before pulling Kit in for a kiss.

"She's like you, isn't she?" Claire asked.

"Yup! I did a little experiment yesterday. Jackie here cut loose her first load of parasites. Given the incredible sex changing properties of my strain of the parasite, I wanted to know if they could infect female hosts on their own. My experiment turned out to be a resounding success."

"Bonnie, what have you done?"

"Come on, Claire. Don't tell me you're still fighting this."

Brynn chimed in, "It's pointless, sis."

"You turned that poor girl into a dude!"

"Yeah, and she isn't the only one," Bonnie said. "I've been very busy in the last twelve hours."

"But why? Why spread this further?"

"Tell me something, Claire. Do you feel bad now that you're infected?"

Claire thought about it for a moment and the answer was obvious. She felt incredible. Strong, healthy, energetic, and sexy. Every sense was magnified in the best way possible. She shook her head.

"Don't you want others to feel as good, sis?" Brynn asked.

The question immediately sparked a new instinct in Claire's brain. She imagined every boring, normal person in her life. What would it be like if they transformed into a superior version? It was an exciting prospect.

"You have a point."

"The train has already left the station whether you like it or not, Claire. I spent today at the lab converting as many people as I could. Almost all of the women are turned - I used Jack's parasites on some of the more dominant chicks and used Rex on some of the weaker men"

Claire tried to imagine Bonnie rampaging her way through her workplace. The image was such a far cry from the woman she knew, and yet there was something deeply arousing about Bonnie's new dominance.

"Why do all of that? Don't you want to keep a low profile?"

"Isn't it obvious? The lab has all of the tools necessary to study, enhance, and propagate the parasites."

"Bonnie's already promised us all jobs! Isn't that exciting?" Brynn gushed.

"Chill, you're going to be a glorified secretary," Jackie muttered.

Brynn grimaced and slapped the blonde hard on her plump, voluptuous buttcheek. Her hand left a red imprint on the pale, delicate flesh.

"Hey, what the hell?!"

"You're always trying to harsh my vibe!"

"Your sister and my intern have been battling it out like siblings since this morning. I don't know what it is with them."

"Probably that this crazy she-beast tried to rape me and turn me into a dumb meathead," Jackie blushed as she realized how that implicated Bonnie. "Not that you're a dumb meathead. You're amazing."

"You might have to share me with Jackie quite a bit. She's head over heels for me."

"That seems par for the course around here," Claire said. "Brynn, play nice."

"You don't get to boss me around. I'm not a little kid anymore!"

"Heh, maybe, but with these new guns I could probably kick your ass!" Claire said. "Is Alex still being an ass?"

Brynn's ferocity disappeared quickly.

"We talked."

"Your worms are especially potent for some reason. I'm just starting to come down from my transformation now. For a while, I was really hot headed and aggressive. I think Alex underwent something similar. You shouldn't take it personally," Bonnie said.

"I know, it still hurt. He apologized, but I don't think he'll ever be fully mine."

"It's not like you're fully his either. You rode poor Kit like a horse last night."

"So did you!"

"Don't change the subject!"

"I'm just glad you guys talked. I wish you hadn't had to keep your feelings to yourself for so long. Maybe things would have been different if you told me," Claire said.

"What fun would that be? Now we get to be proper sisters!"

"I'm inclined to agree, Claire. I get to have sex with my hot best friend. It makes the whole sex change much easier to swallow."

Claire couldn't hide the troubled look on her face, however. Before she knew it, there multiple pairs of eyes staring into her soul.

"What's wrong, sis?"

"This plan you guys have - to spread the parasite all over the place. It just seems wrong. Isn't that the type of thing villains do?"

"It's not a movie," Bonnie giggled.

"Look at me, sis. You remember how I was, all skinny and boring. The parasite gave me these!" Brynn cupped her enormous, bubbly swells. "It made you all sexy and strong. Do you really want to keep fighting this blessing?"

Claire thought about it for a long time. Her mind clung to her morals, but her heart felt differently. She could feel the parasite working on her brain, cajoling her to its side. She considered fighting it; after all, she didn't like things that messed with her head. Then she looked at her company. Brynn, once too shy to show her face in public, was now vivacious and beautiful. Jackie, formerly Jack, was once a cantankerous nerd. Now he, or rather she, was one of the most beautiful women Claire ever saw, and she seemed to know it, too. Finally, there was Bonnie. The parasite had taken her best friend and transformed her into a hot, she-husband. The thought of a life spent in this burly goddess's arms finally pushed Claire over the line.

This is the new me. It's who I am, and I might as well embrace.

Claire dropped the last chains of humanity and embraced the little wigglers in womb. She imagined the mutated scientists at Bonnie's lab working day and night to create new, more potent parasites. She imagined thousands of nerdy, dorky girls like Brynn transforming into buxom hotties. There would be women like Bonnie too. Feminine, poised women transformed into horny, bestial she-hunks. Before long, she was wet as a mop.

She looked Bonnie right in the eyes and smiled for the first time in days.

"I'm in."
