Product Testing Pt. 03

Note: This story contains much more sex than previous chapters and includes elements of breast expansion, cumflation, penis growth, and other minor body transformation themes. If these do not interest you, I recommend reading a different story.

Product Testing is an anthology. As such, each chapter focuses on different characters and can be read independently of the others. Each chapter will do some world building, but reading each chapter is not a requirement.

Dani woke suddenly. She was normally very groggy in the morning before she got her caffeine, but not today. Today, she was wide awake and ready to go.

"Go where?" you might wonder. And truth be told, she quickly wondered the same. She wasn't at home, but in some run down motel somewhere. Odd. Peeling wallpaper, dirty bedding, filthy mattress, awful smell... she'd be lucky if no one had been murdered in this room. Hell, she'd be lucky if she wasn't murdered in this room.

The old TV in the corner suddenly turned on with a loud CLICK. The TV had seen better days and she could just barely make out what appeared to be a factory line amidst all the static scanlines. If there was audio, she wasn't hearing it.

Dani got out of bed, stretched, and looked down at the orange jumpsuit she was in. Not her usual style, but she could dig it. She went over to the mirror to freshen up, picking the crust from her eyes and using her fingers to comb all of her hair over to the right side -- the left side of her head was shaved clean, the right side a mix of green and purple hung to her shoulders. She had multiple piercings in her ears, a nose ring, an eye brow ring, and a lip ring.

She jumped up and down a few times and rotates her shoulders in their sockets and rotated her neck, working out some kinks.

The odd room had only confused Dani for a minute. Then it had all came rushing back: she had signed up to be a product tester. The agreement was simple: they'd put her to sleep for a period of no more than 10 years, she'd wake up having not aged a day, they'd run her through a few tests, and she'd walk away with a monthly stipend of $20,000 for the next 30 years.

It was too good to be true. She had just gotten out of a bad relationship with her manipulative ex-girlfriend and hadn't spoken to her family in years, so the lost time would be nothing for her. It essentially amounted to a day or two of work in exchange for a $240,000 salary for the next 30 years.

The woman who had done the onboarding, a younger woman named Anne who should really lay off the cigarettes, had mentioned Dani might experience amnesia when she woke up, but she seems to have gotten lucky.

Dani was rolling up her sleeves, revealing her colorfully tattooed arms, when the door to her left clicked and opened. She walked through it and heard it immediately shut behind her, very eerily. In the hallway, she looked left and saw a dark hallway except a single light still on over it about 50 feet down. To her right, it was mostly darkened too but she could see a bright light at the end of it. She looked back at her door and saw "31209" on a tag below her light.

Excited to get going, she walked at a brisk pace toward the light at the end of the hallway, assuming that's where she needed to go. Reaching it, she was met with elevator doors that opened automatically. She entered the dingy elevator with a flickering light in it, and wondered why it was so poorly maintained.

The doors closed and the elevator started descending. She was a little weirded out by how far down the elevator seemed to be taking her, but she assured herself it was worth the money at the end of it.

Finally, the elevator stopped. The doors opened to... well, just white. It was blinding. She couldn't make out where the ceiling or walls were. Looking down, she could barely even make out her own shadow. If she couldn't feel the floor below her, she'd have thought she was floating. She heard the elevator behind her close, looked over her shoulder, and saw the doors completely disappear into the white.

"Welcome, 31209, to Product Testing," said the Speaker. "Judging by your reactions so far, you are not experiencing any amnesia and remember your orientation, correct?"

Dani yawned and stretched again, staring at the only non-white thing in the room: a toothbrush sitting vertically on a thin metal stand in the center of the room. "Uh... yeah, I remember everything, boss-man."

"Splendid. Then let's commence. Starting recording. Subject number 31209. Female. 32 years old. 5 foot five inches. 128 pounds. Sexual orientation: homosexual. Natural hair color: blonde. Hair color at present: purple and green, left side of head shaved. All body functions normal. Numerous piercings found in ears, eyebrow, nose, lip, nipples, and navel. Tattoos cover much of upper body and parts of lower body."

Dani nodded along as he listed off the attributes Anne had recorded during orientation.

After a moment, the Speaker returned and said, "Okay, 31209. Today, you will test two products. First up is T981-102. This toothbrush does not require toothpaste. It will clean your teeth better than any toothpaste on the market."

"Well, that's certainly cool," Dani said, still looking around the room in curiosity. Truth be told, she was already bored with this test. A mirror appeared on the far wall, seemingly out of nowhere.

"Before testing, walk to the mirror and observe your teeth, lips, and tongue closely," the Speaker ordered. As she walked to it, he added, "Please remember that the goal of these tests is to observe how well the products work and any changes between before and after use. Please verbally describe everything you see, feel, hear, taste, and smell today."

"Yeah, yeah," Dani muttered. Anne had given her the same directions in orientation yesterday. Well, it felt like yesterday anyway.

Dani looked at the mirror at her lips. They weren't anything special, but weren't thin either. "My lips are a light red. Anne made me remove all makeup so my lips are plain," she said, before licking them and adding, "And very dry today."

She pulled her lips back to bare her teeth, rolling her head back and forth to see them at different angles. "My teeth are fine, although a quite yellow. I really need to see the dentist more often."

She stuck out her tongue. She observed how white it was and then did a few twists and twirls with it. "My tongue is a little thin and a little white from non-cleaning. I have great control over it though."

She cupped her hands in front of her face and breathed heavily into them, cringing a bit. "My breath smells awful. You guys should figure that out in your sleep procedure."

The Speaker seemed to ignore the criticism and responded, "Thank you, 31209. Please proceed to the pedestal and use the toothbrush as you normally would."

Dani walked over and picked it up. It was very unremarkable. A red, semi-transparent handle and white bristles. Like it had been drawn for a kid's cartoon. She touched the bristles and they were entirely dry, but there was no sink to be found. Shrugging, she lifted the toothbrush to her mouth and started brushing. Her eyes widened at the sensations she was feeling.

First, the bristles were wet and foaming in her mouth. Just like toothpaste would. She pulled the toothbrush back out and examined it again before reporting, "My mouth was immediately filled with liquid and foam, like any other toothbrush and toothpaste. But the toothbrush is still completely dry."

She went back to brushing and started feeling her mouth get full of the foam, but just as she was wanting to spit it out, disappeared. "My mouth filled with foam, but before I could spit it just... disappeared. Was it absorbed by the toothbrush?"

This one got a response from the Speaker, "Your body absorbed the chemicals, actually. Please continue."

Well, okay then. She continued brushing for a 15 seconds as her brow lowered and her eyes focused on the stand in front of her. She took the brush out and said, "My mouth is warm. Much warmer than it was before. My lips too. Is that normal?"

The Speaker returned, this time sounding almost annoyed, "It is your job to test and observe 31209. Whether it is 'normal' will be determined based on your data."

Seems she struck a nerve.

She continued brushing until the warmness went away, probably another 40 seconds or so. "My mouth isn't warm now. But it does feel... weird. Numb almost."

"Thank you, 31209. Please replace the toothbrush and return to the mirror to report any effects."

She put the toothbrush back on the stand haphazardly, watching it fall to the floor. Shrugging, she turned and walked to the mirror.

Dani was struggling to understand what she was seeing. "Uhhh... my lips. They're dark green! And they seem a little fat. Nothing bad, though, they look great!" She rubbed at her lips a bit. "The lipstick isn't coming off either. Almost like that's their natural color."

She smacked them together and blew herself a kiss. "Oh! They're really moist now too."

She bared her teeth once more and was again pleasantly surprised. "My teeth are pearly white. They're so white, they'd probably glow in the dark! I look like a movie star!"

Well, except one thing. She eyed her canine teeth for a moment before reporting, "I... have fangs. Short ones, but definitely fangs." She smiled to see how they looked and was unexpectedly happy with them; the fangs completed her look, she thought.

She stuck out her tongue and again was shocked. "My tongue is spotless BUT it's also split. Like a snake's."

She did some more twists and dances with her tongue before smiling naughtily, "I seem to have full control over both sides of the tongue. That's going to make some people happy very soon."

She was still observing herself in the mirror when the Speaker returned and said, "Thank you for the report, 31209. Please return to the elevator and we will begin the second test."

She backed away from the mirror as she heard the elevator open, smiling wide and using her tongue to wave herself goodbye. This was awesome!

Back in the elevator, she felt like a million bucks. These were all things she may have done to herself on her own. And instead, she got paid to do it. And got paid well!

She was grinning as the elevator's descent stopped and let her off. It opened to a near-identical room -- all white, nearly blinding. Except there was no toothbrush in this one -- no, instead there was a tray on the stand and on that tray was a harness and a large, purple dildo. A strap-on!

The Speaker began speaking as soon as she eyed it, "P481-3 is a highly experimental product from our Sexual Wellness group. Are you familiar with a 'strap-on' as it's commonly referred to?"

Dani covered her mouth as she laughed. "Uh, yeah boss-man. I'm plenty familiar with these bad boys."

"Good," the Speaker remarked. "This test will be conducted in two parts. The first part is simple -- put the harness on, slip the dildo in, and describe how it fits and feels. Play with it as you see fit."

Dani nodded and stepped up to the tray. Realizing this would be difficult with her jumpsuit on, she started stripping before boss-man could order her one way or the other. She took it off, the white shirt underneath it, and even the panties she had on. Completely naked, she quickly reached up to twist the rings hanging from the nipples on her C-cups. She groaned before doing a few quick hops and neck spins like she had done after waking.

She calmed down and picked up the harness. It was just like any other harness she had used before and she quickly had pulled it up her legs and had it tightened so it wasn't going anywhere.

Then she glanced at and picked up the purple dildo. Examining it, she was surprised by how realistic it was. With a perfectly helmet shaped head, very finely detailed skin pores, and even stubble on the shaved testicles, she could tell it was modeled after a real penis. Well, except the size. It had to be 12 inches long and thick as a cucumber.

"The harness fits well and seems to be standard equipment to me. The dildo is disturbingly real looking. I'd argue it's probably a little too big for playtime, but I'm sure I could find a way to have some fun with it. The heaviness will make it difficult to use for prolonged periods, though."

She reached down and slipped the dildo into the ring of the harness and made sure it was tight and secure against her body, positioning the dildo so it hung directly over her sensitive clit.

As soon as she had secured it, her eyes opened in surprise and she fell off-balance, slightly lightheaded.

"Oooh. Oh my. As soon as I strapped in the dildo, my clit grew very warm and it was like I was halfway to an orgasm."

Looking down, she held the heavy dildo in her hand and... what? She lifted it, and then smacked her other hand with it. No, she wasn't imagining it.

She said quietly, almost unsure of what she was about to report. "I... I can feel the dildo. Not the dildo touching my body, no I can feel the dildo itself like it was part of me. How?"

The Speaker returned and said, "Correct. That was the objective of the Sexual Wellness team."

"Woah," Dani said in amazement. Then she remembered what boss-man had said earlier: Play with it as you see fit. You got it, boss-man.

She let go of it and it fell to hang down to her knees. She felt the air rushing around the dildo and it swinging back and forth. She felt it bounce against her thighs and then brush against her right thigh as it came to a rest.

Excitedly, she picked it up and did what any curious girl with a new penis would: stroked it. Fireworks went off in her head after just a few strokes, the new pleasure she felt overwhelming her senses.

She breathed heavily. "Uh... uh... uh... wow. I orgasmed after just a few strokes of it. And did it..." she gave it another few strokes before continuing, "... it did! It even seems to have a foreskin that moves!"

She backed up against the wall and fell to the floor, and leaned over to spit on the dildo. Grabbing the massive toy with two hands, she started stroking it again. She laid her head back against the wall, closed her eyes, and just relished in the pleasure. Every pump felt like heaven. And under the harness, she could feel her own pussy getting wetter and wetter.

She moved her left hand higher and played with the head and nearly jumped at how sensitive that area felt. But it also felt... her eyes darted open.

"The head of the dildo is... leaking," she said with a hint of confusion.

She kept stroking and felt her pussy get wetter just as more liquid exited the tip of her fake cock. She wiped at the liquid with her finger and tasted it. It tasted slightly salty, but not unpleasant. She did the same with her own secretions.

"It seems to leak in time with my pussy. But it's not the same taste. I'm unsure what it is," she said.

Dani slapped the dildo up against her belly and then against her own hand. She liked how strong and powerful she felt, slapping her big slab of "meat" against her palm. She continued stroking her fake cock while fondling the balls now. The combined sensation shortly sent her over the edge.

"Ungh. Ungh. Ungh. Ungh. Ah... ahh... ahhhhhhh," she moaned with her eyes closed and fangs biting her swollen bottom lip as she came a second time. So powerfully this time, she lost control and squirted three small gushes from her pussy.

She was catching her breath when she slowly opened her eyes and looked down for yet another shock. "Did the dildo cum? There's white liquid on my chest! Is that sperm?! How?"

The Speaker returned, "The Sexual Wellness team appears to have exceeded their objectives. Please proceed to the far wall where you will find a water and towel to clean up with."

Dani stood -- shakily -- and walked to the far wall where a cubby hole with a water bottle and green towel had magically appeared in the white wall. She grabbed the water bottom, tore off the cap, and drank the entire thing in one swig. "Ahhhh," she said in relief. Then she took the towel and wiped the cum off her torso and cleaned up below the harness.

A few minutes passed and Dani's breathing finally calmed down. "This is the best sex toy I've ever used. Can I please keep it?" she asked the boss-man.

The Speaker very matter-of-factly said, "No. This product is an early prototype and not yet ready for production. If you are ready, please proceed through the door."

"What d..." she began asking as one appeared in the wall right next to where she was standing. Magic. This entire place was magic.

She put the water bottle back, but took the towel and strap-on with her through the door into a long hallway. Going through the only other door, she entered -- you guessed it! -- another white room. Only this one didn't have a pedestal, instead there was a bed with light gray bedding on it that looked black with all the white everywhere.

She sat on the edge of the bed and waited. A few moments later, another door opened and another girl walked in. She seemed a little frightened, but Dani felt the naked girl was cute. She looked in her late 20s and had a very thin frame with a fairly flat chest. Her black hair was cut into a bob. Her ears were pierced just once each, and she had a tattoo of a rose on her left calf.

Dani stood and noted she had maybe 6 inches on the girl in height. The girl saw Dani, looked at Dani's crotch, and stopped like a deer in headlights.

"31209. This is subject 54287. The second part of your test is to get... acquainted with her," said the Speaker.

Dani looked on in confusion. Was he expecting Dani to force her new best friend into this woman? No, she refused.

Instead, Dani walked over to the girl and wrapped the unsullied side of the towel around her shoulders. Dani walked the girl over to the bed.

"Ignore him. I'm not going to force you to do anything. I'm Dani. What's your name?" asked Dani as she she sat next to her, arms brushing together.

"My... my name is Becca. I don't know where I am or why I'm here," the sexy girl said.

Wait... sexy? A minute ago, Dani had just thought Becca was cute. Shaking her head, Dani softly said, "It's nice to meet you Becca. You're like me and signed up for some product testing. I'm guessing you're dealing with the amnesia that I lucked out on."

Dani looked at Becca's soft facial features. Her small nose. Her thin eyebrows. Her brilliant green eyes. Her chin and cheeks you could just get lost in.

Dani shook her head again. What was happening?

"Er... you've sprung a leak, Dani," Becca said, breaking Dani's spell.

Becca reached down and touched the tip of the dildo. The second she touched the liquid, her entire chest inhaled deeply, her pupils widened, her cheeks reddened, and her small nipples hardened.

Dani felt Becca's change in composure and felt a voice in her head tell her, "Take her! Do it!"

Dani resisted the voice, but she needn't have. Becca let out a quick, "Oh," and started rubbing her pussy with one hand and grabbed the dildo with the other.

Dani laid back and groaned in pleasure as Becca gave her a handjob. It was different than stroking it herself and a hundred times better.

Dani felt a hunger in the pit of her stomach suddenly and grabbed Becca, pulling her tiny frame up onto the bed and positioning her ass right on Dani's face. Dani eagerly started eating Becca's pussy, as the girl got more and more aroused. After a minute or so, Danni pushed Becca's back downward and she fell into position to sixty-nine with Dani.

Dani groaned loudly when she felt Becca take Dani's fake cock into her mouth. All of the sensations felt real and they were making Dani so very lightheaded. She kept eating the pussy in front of her when Becca surprised Dani by inserting 2 fingers into Dani's pussy while sucking about half of the dildo.

That was enough for Dani. She pushed this fine woman's ass off her face and spun Becca so her head was near the pillows and ass in the air.

"Come get it!" she giggled as she shook her surprisingly fat butt at Dani. Egging her on, Becca added, "I mean... if you're man enough..."

Dani growled and scooted over to Becca, grabbing her ass and leaning down to lick both Becca's holes, causing her to squeal. Dani grabbed her fake cock and rubbed it against Becca's pussy lips -- once, twice, three times -- accumulating some lubrication.

On the fourth swipe, she pressed the giant dildo into Becca's pussy, eliciting a guttural groan. Dani felt a lot of resistance, likely due to how thick her cock was. It took some movement, but eventually she was able to push it in far enough to start fucking Becca properly.

It was slow at first, but their combined lubrications quickly made it easy goings and they got into a nice pattern. Dani would thrust forward, Becca would thrust back while thrumming her clit below, and Dani would grunt while Becca would let out a high pitched moan.

Dani couldn't believe how good this felt. She had fucked women with strap-ons so many times she had lost count. But this time? This time it was like the strap-on was actually just her cock. And she felt it. Every last bump in Becca's pussy. The smooth folds. The slick wetness. The warmth. she felt it all and the bedding below both of them was wet from it.

"Oh Dani. Fuck me, fuck. Fuck! Cum... I'm going to cum. Please cum with me! Please please please," little Becca pleaded.

Dani issued her response non-verbally. She leaned over, wrapped her hands around Becca's torso, and stood back up. Now both vertical, Dani kissed Becca's neck and tweaked her tiny nipples as she grunted heavily.

"Yes, yes, yes, yes, yes! Ooooooh!" Becca moaned loudly as she came.

It took Dani a few more thrusts, but she too came with an unbelievably good feeling warmth spreading in her pussy. "Oh god yes! I've never felt this good before! This alive! Take it, Becca. Take my cum!"

Becca's eyes shot open as she felt herself being filled. How was that possible?

Dani fell over after she finished climaxing and laid on the bed, pulling Becca down with her. They spooned for a few minutes, enjoying each other's warmth as they calmed down a bit. Becca reached down to confirm -- yes, Dani had cum in her.

Becca asked her, "Dani... how did you cum with a strap-on?"

Dani sighed and said, "I don't know. It's the product we're testing. I can feel it. Like it's part of me. It leaks precum as I am aroused and physically cums when I do. I don't understand it, but I never want to take it off."

Becca sat up and turned over to examine it. Only it wasn't there anymore.

"Uhhh..." she said as she pointed at Dani's crotch to grab her attention. Dani looked down confused, and then jumped up out of the bed into a standing position.

Gone was the harness. Gone was the dildo. In its place was a large, pale white cock. It was soft, but even soft it was a good 5 inches long. It was resting on massive balls.

Dani stared in shock, reaching down to examine. She touched it, and it felt even realer than the dildo had. She lifted up her balls -- that's the weirdest fucking thing I've ever thought, she said in her head -- and discovered her pussy was gone. She wasn't surprised, given the massive cock sitting in its place. But she was a bit saddened by it.

Becca slid off the bed and was on her knees in front of Dani, mesmerized. She lifted the cock up to look at it in more detail. Her eyes hadn't deceived her -- Dani had a cock. She moved it side to side, lightly touched the balls, and then looked under them.

Becca gasped. "Your pussy... it's gone. It's just cock!"

Dani looked down at Becca holding her balls and staring back up at her. "Ugh. I know! What happened to me?"

Under Becca's continued examination, Dani's cock started to harden. As it did, Becca started lightly fondling Dani's balls. Becca looked back up into Danni's eyes and smiled mischievously, giving her a few strokes.

Nearly at full length, Dani could see now that the cock was identical to the dildo. 12 inches, thick as a cucumber, big and heavy balls.

Reading her mind, Becca said, "At least it's not purple."

"Says you! I would have liked the splash of color," Dani laughed. Then she added with a grin, "And you could have told the world you got fucked by Barney."

It was Becca's turn to laugh, falling back on her legs as she stifled it behind her mouth. "Yeah, now I'm disappointed too!"

Dani was at full mast now and a drop of precum had formed on the end of it and was started to drip toward the floor. Seeing it, Becca got back up and said, "Nu uh uh uh. This is all mine!"

She got up under the drip, opened her mouth, and followed the drip to the source, kissing the head tenderly before sucking half of the shaft into her mouth. "Well, that might be the sexiest thing I've ever seen!" thought Dani.

Becca backed off it before pressing the side of the cock against her lips, kissing it, and then running her lips up and down the side of it. Each pass coated Dani in more saliva that Becca would spread with her hands.

Dipping down lower, Becca stared up at Dani before grinning and sucking a ball into her mouth. "Oooooh gawd," Dani moaned, her eyes rolling back in pleasure.

Becca switched to the other balls, rolling it around with her tongue before quickly sucking the head back into her mouth. Danni reached down, grabbed some of her hair, and started guiding Becca's head up and down the massive cock. Becca didn't seem able to take more than about half, but it was still wonderful for Dani.

Dani put a finger under Becca's chin and lifted her to her feet. Dani mashed her swollen lips against Becca's and started to kiss her passionately, tongues darting in and out of their mouths, unable to get enough.

Dani backed Becca up until her legs hit the light gray bed. She ended the kiss, grinned, and pushed Becca back onto the bed. "My turn!" she said in a raspy voice as Becca moved to the center of the bed and Dani followed.

Becca looked down as Dani moved between her legs. Dani kissed the inside of Becca's left knee and then slowly, agonizingly, kissed up toward her vagina. Reaching it, she placed a single kiss on the small landing strip above it and then pulled back, kissing the inside of Becca's right knee and repeating the process even slower. Becca was annoyed with the teasing and grabbed a handful of hair from the unshaven half of Dani's head and positioned her mouth where it belonged.

Dani got to work, licking up and down Becca's slit a few times, and ending by sucking her clit into her mouth and licking it side to side for a moment. Becca smiled widely and leaned her head back as she groaned happily.

Dani continued this for a bit, getting Becca breathing heavily and moving a bit before taking it up a notch. She took her transformed tongue, placed Becca's clit in the new split, and started rotating the two sides in opposite directions over and over.

This change pushed Becca over the edge. She grabbed onto the sheets and lifted her entire pelvis off the bed, legs quivering she she did. "Wha... wha... oooooh.... right there... more more more... there! Right there!" she shouted.

Dani kept at it as Becca climaxed and eventually pushed Dani away, her entire body lightly shaking as she came down.

Dani crawled up and laid next to Becca and just looked at her face with a grin. Becca was dripping with sweat and out of breath, eyes closed, and her face shined with bliss.

"That... was... awesome." she eventually said. She opened her eyes and gave Dani a quick peck on the lips. "What did you do to me?"

Dani smiled mischievously and said, "Well, this wasn't my first test. The first split my tongue in two and did something to the muscles. I have some new talents now." Dani mimed filing her nails like it was no big deal. "Oh! And my teeth are perfectly white and I have fangs now. We'll need to play with those later," Danni added with a sly grin.

Becca looked down and saw Dani's massive cock was still hard as a rock and laying on her belly. "You didn't let me finish earlier..." she said as she pushed Dani onto her back and slid a leg over her middle.

Dani watched as Becca rested her slit on the long rod. She leaded down real quick to kiss Dani one more time before sitting up. She reached down and held Dani's cock in place as she slid her pussy up and down the full length, coating it in her juices.

Becca slid a little further forward one one cycle and when she slid back, the head entered her hole, followed slowly by the rest of the shaft. She held still a moment and gasped "So full. Ahh."

Adjusted, she started rocking back and forth. Dani placed her hands on Becca's hips and started urging her to lift up, wanting more movement. Becca took the hint and started lifting up and falling back down, over and over. Dani started thrusting to meet her in the middle and they eventually developed a rhythm.

Becca leaned over Dani and they quickly kissed again as she rode. Back into position, she tweaked Dani's pierced nipples, eliciting a loud groan. Dani flipped Becca onto her back, letting her more dominant side take over. She thrust into Becca as hard as she could, reveling in the feeling of the tight pussy pulsing around her cock.

Her cock. What a day. She woke up assuming she'd be part of some focus group or have to take a pill. Instead, a strap-on had literally given her an unbelievable large cock that she was now ready to unload into a stranger she felt like she had known her entire life.

"Yeah, Becca. Take it, you horny slut! Take my cock! Take my big girlcock! Let it fill you! Let it breed you!" she grunted at the girl below her.

Placing her hands on Becca's small tits, Danni squeezed and pressed on the nipples with her palms. She was so close.

"YES! Give it to me, Dani! I'm your slut. Fill me! I need it! I want it! Give it to meeee," she groaned.

Dani felt her balls lift as she went over the edge. Roaring loudly, her cum rushed out of the shaft like a hose and filled tiny Becca. One... two... three... the blasts of cum left her. Four... five... six... seven... they were showing no signs of slowing down. Dani kept cumming and cumming.

Becca let out another groan as she felt it filling her. "Oh... wow. Oh my. What is happening to me... my chest feels so warm. And my belly too!"

Under Dani's hands, she could feel the heat and watched greedily as Becca's nearly flat tits grew in her grip. The small areolae tripled in size, the nipples grew twice as long, and the tits themselves swelled and swelled until they were a little larger than Dani's own.

Grinning, Dani urged her cock to keep spewing her seed. Becca's tits seemed to be done growing, but her belly inflated as it was filled, giving small Becca a beer gut. Or a cum gut, she wickedly thought.

"Ungh! Ungh!" Becca moaned as she climaxed again.

Danni finished unloading in her partner and laid down next to her again. Looking down at the transformed Becca, Dani couldn't believe how attracted she was to the girl now. Even the bigger belly was sexy as all hell. She leaned over and kissed Becca once more, looking deeply into her eyes, and simply said, "You're incredible."

With a quick smile, she started kissing Becca's neck and kneading at her expanded left tit. They were not done. Far from it.

In the observation room sat a lone scientist in a white labcoat, watching the two women seemingly fall for each other. He reached for and pressed a button next to the mic in front of him.

"Test P481-3 results... inconclusive. Product worked as expected -- Subject 31209 felt the dildo in the strap-on as if it were her own. It responded to her arousal and climaxes as expected and did well in use with a partner," he said as he read over some notes.

"However, after experiencing an orgasm while penetrating Subject 54287, 31209 absorbed P481-3 and 31209 now has an obscenely large, working penis in place of her vagina. After inseminating 54287, 54287's stomach swelled and her breasts seemed to have permanently expanded 3 or 4 cup sizes," he sighed. "As with most early tests of products relying on the Chemical I discovered, it has resulted in unforeseen, uncontrollable modifications to the subjects."

"Further, the liquids from both the dildo and the penis seem to have some sort of aphrodisiac qualities. This will require further study. Recommendation: use a higher silicone-to-Chemical mixture in the next iteration. This could be a highly successful product once we work out the modifications it is causing."

The Speaker shook his head as he ended the recording and watched 31209 fuck 52487's expanded tits. Picking up a phone, he dialed maintenance and said, "It's me again. Send a crew to the P481-3 room in an hour or two. They'll need hazmat suits... yeah, again... yeah, it's infectious. Don't touch the semen. Yes... okay... thank you."

He hung up the phone, took a bite of an apple, and then walked to the back wall where an elevator appeared out of nowhere.
