Quarantined due to Futa Virus.

Riley sighed. He was grateful that he had thought to bring a particularly large and thick comic book for the trip to his aunt's house. Quarantine due to the Futa virus would've been extremely boring without it. But there was another benefit to the voluminous superhero collection resting on his lap, it was perfect for hiding his boner in the middle of the living room.

What was the cause of his current awkward erection? That would be his milf aunt and bombshell older sister. Both completely were nude in said living room and currently fucking like there was no tomorrow.

"Yes! Fuck me, Aunt Brooks! Fuck me harder!" Riley's older sister, Cali, was leaning forward against the same couch that Riley was reading on. Her impressive E cup tits bouncing back and forth as their aunt rammed a massive futa cock into her niece.

"Stop swearing, Cali." Aunt Brooks said in an authoritative voice, even as she pounded the teenage pussy of her nineteen year old niece. "It's my house and I'm telling you to stop swearing. I don't want to punish you by fucking you this hard."

The plopping sound of thigh meeting teenage ass could be heard throughout the house, so even if Riley went to his guest room he wouldn't be able to escape the erotic noise. So it was better to stay in the one comfortable chair and watch the show, even if it was really embarrassing to watch his sister get fucked.

"Keep fucking me harder, Aunt. You know you love it!" Cali replied, ecstasy filling her voice. She was a prospective college student, and a bombshell that would have looked more at home in a sorority house than in a business minded aunt's house.

Cali was about to start another term at the local college in the northwest US and had brought along her eighteen year old younger brother Riley to visit. Since they didn't have money for a hotel, they had bunked at their aunt's house for what was supposed to be a week's visit. That had turned into a month's visit after the quarantine was declared. Despite the quarantine, infection had found its way into the building and both women had transformed into futas nearly overnight a few weeks ago.

Riley was a bit freaked out at first, thinking he'd die from the virus or get transformed into a freak like his sister, but instead, nothing. The doctor on the tele-health service had said something about possible immunity but they would have to wait to see if it wasn't just a delayed reaction. Until then, the eighteen year old boy was stuck here. Watching his aunt fuck his sister silly with a massive 15 inch futa milf cock.

"Do you have to do that in the living room?" Riley grumbled loudly enough to be heard above the debauchery.

"Oh fuck off." Cali replied, her 10 inch cock spurting steaming hot jizz onto the couch as she orgasmed for the third time that hour.

"Language!" Aunt Brooks ordered, slapping her niece's ass with the answer to the riddle of the sound of one hand clapping.

"Eep!" Another dollop of cum soaked the couch. "Bro, just be grateful you didn't croak from the virus like a lot of other guys did. Or worse, get freaked out."

There were indeed some videos and pictures online of some guys who had been affected by the futa virus and getting some truly bizarre additions to their bodies. But there was a lot of debate on if they were AI generated or not. Guys growing five feet dicks, multiple cocks, balls the size of hummers, or more unbelievable, turning into futas with all those things. It tested the gullibility of the average internet rover.

"Oh fuck." Aunt Brooks muttered orgasmically as she pulled her fifteen inch phallus out of the teenager with a sudden movement. "I'm cumming!"

A fountain of cum spurted from the milf cock, along with twin jets of milk that erupted from the mountainous melons that were Aunt Brooks G cup tits. Whether her lactation was from the futa virus or if she had always been able to do that, she never told the teenagers.

"Ahh! My book!" Riley dashed out of the way to shield his reading material. His comics were saved, but half his body was now as soaked by sex fluids as the couch was.

Once her balls and stamina reserves had run out, Aunt Brooks stumbled over to her favorite chair and collapsed in a sexy heap. Cali flopped down on the couch, the fabric making various sounds that a couch should not make as her naked flesh nearly swam in her own cum and aunt's tittie milk.

In her prone state, Cali saw under the book that Riley was using to hide his average manly chub that created a tent in his shorts. She sneered like a cheshire cat at the cock that was clearly several inches smaller than hers.

"Aww. Look at the cute little guy. Does the manly little dick want a pity fuck?" She then made a derogatory gesture in the air that both Cali and Aunt Brooks chortled at. But the older futa caught herself and chided her niece.

"Don't make that gesture, Cali. Guys won't like it. And Riley, if you need relief then you can use my pussy. You got infected too and probably need some sexual tension let out more than your sister does." Aunt Brooks spread her sexy legs over the arms of her chair, underneath her decent sized balls was a pussy that almost looked like the gates of heaven to Riley.

So many times during puberty he had thought of his busty milf aunt, and now the opportunity was calling like a siren. But unfortunately his pride had already been stung by his sister's comments.

"I'm going to the kitchen to get something to eat." The semi-muscular teen boy lugged himself up and stalked to the other room in a huff. He tried to block out the female laughter that followed in his wake.

When he reached his destination though, he realized there was absolutely nothing he knew how to make. Of course, there were a couple ingredients he recognized. But he had less than no cooking skills.

After a long enough look to justify leaving the fridge open to cool his member down, he sat down at the small kitchen table with a jug of milk, a carton of OJ, and a box of cereal. A true bachelor's breakfast, even though it was nearly lunchtime.

Halfway through his meal, Cali strutted in. Her bare tits bounced seductively and her half flaccid cock swung hypnotically.

"Hey, Bro." Cali nodded towards her brother, who responded with a surly grunt.

The teenage 19 year old futa opened the fridge to find some refreshment, the vigorous fucking she had been enjoying all day had left her sweaty and mildly depleted. But when she realized that the milk jug was missing, she smirked in her 'older sister teasing' way.

"Enjoying the milk, Riley?" She with a smug grin. Yet another grunt. "Y'know. Milk has gotten really expensive recently, and did you know there is a side effect to the futa virus?" A confused grunt, Riley was unsure where the conversation was going. "Do you know what that side effect is?"

Something was setting off alarm bells in the older brother, but he had no idea what was going on. He put another spoonful of cereal in his mouth.

Cali sidled up to her brother, her E cup tits getting way too close to him. "Lactation."

All at once, the pieces fell into place for the clueless male. "PHTOOIE!" He spat out the milk and cereal against the kitchen wall and began downing the OJ carton to drown out the taste of his sister's milk. Not that it had tasted bad, but he couldn't get over the fact that he had been drinking something from his sister's tits.

"Don't drink too much of that." Cali said as she doubled over laughing at her brother's reaction. "Aunt Brooks has been cumming in there to keep from paying for more juice. It's been watered down to where it's barely OJ anymore, not sure why it's still orange."

"PHTOOIE!!!!!" The 'OJ' joined the milk and cereal on the wall.

For the next ten minutes, the only sound coming from the kitchen was Riley gagging and dry heaving. Cali's cruel sisterly laughter barely registered on the decibel scale compared to it.

"Seriously?" Riley asked when he recovered his breath. "Why the fuck would you do this? It's seriously gross?"

However, he never got an answer since his sister was too occupied laughing at him. He stormed off to his room. Trying his best to ignore how lustful the thought of drinking his aunt's cum was making him feel.

After jacking off a few times to some of the new futa porn that was online, he went to bed and fell asleep within minutes. Completely unaware of the changes that were about to take place with his body as a result of his recent ingestion.

When he woke late the next morning, he frowned in confusion. He felt like he had to expend more effort to take a deep breath, as if a heavy pillow or kitten was resting on his body.

Half asleep, Riley swung his legs out of bed and looked downwards. What he saw shook him to his core and he had to repress a scream. What was undeniably on his upper torso was a pair of tits. They were at least C cups, and had a perky shape that nearly invited groping.

"This can't be real. This can't be real. This can't be real." Riley repeated the mantra as if hoping to manifest it to the universe. "This is a dream. This is a dream. This is a dream!"

To his dismay, the tits were real and it wasn't a dream.

The eighteen year old boy rushed to his computer to pull up a medical website. For the first time in recorded history, the website did not give the diagnosis of cancer. Instead it diagnosed the amateur football player with pneumonoultramicroscopicsilicovolcanoconiosis.

Frustrated, Riley searched all over the web for a result, or better yet, a cure. But unfortunately every search result for 'growing tits' was just flooded with futas from all over the world bragging about their new busts. If there was a guy out there talking about something similar it was lost in the deluge.

"Fuck this." The swear was of uncertain literalness since the barrage of boobies had left him extremely horny. "I'm going to get some breakfast."

Out in the hallway, he could more audibly make out the sounds of his sister and aunt fucking in their room. From the various swears and exclamations, Riley guessed his sister had woken first and put her morning wood to good use.

Occupied with his thoughts of his family's copulation and his new tits, he unconsciously poured out a glass of 'OJ' and yet another bowl of milk and cereal. Gulping it down with the healthy appetite of an eighteen year old growing boy.

It was only after he had swallowed the last bite did Riley realize what he had done. "Bleh! I did it again! I drank my aunt's cum and sister's boob milk! It... was good?"

Absent his older sister's teasing laughter, he had time to reflect on the taste that lingered on the tongue and danced on the taste buds. Morbidly intrigued, he poured another glass of his aunt's dick juice.

What came out of the carton was definitely not orange, indeed, the whiteness should have been a hint in the first place if he hadn't been so distracted the other day, he sniffed at the cup of jizz juice. It had a curious scent that was oddly appealing to him. When he had his fill of the aromatical bouquet, he cautiously took a sip, fully taking in the flavors.

To his surprise, he quite enjoyed it. Within seconds he had downed the glass and poured himself a second and a third. Soon enough, the carton was empty and his tastebuds were saddened by the loss of sensation.

Next was his sister's tittie milk. Once again, he proceeded cautiously. Once again, he was amazed and thrilled by the taste and downed the carton.

"Fuck. That was good!" He wiped his mouth with his arm and smacked his lips a few times in satisfaction.

But the afterglow of a stomach full of liquids was interrupted by a strange gurgling from his body and a sudden pain from his groin. It lasted less than a second, but it seriously stung.

"Fuck! What was that?" Riley looked down and was shocked by what he saw. Past his new tits, that may have grown even bigger, was a dick that even a porn star could be proud of. His previously 6 inch dick was now at least 9 inches and was definitely thicker.

"Holy shit..." The implications and calculations slowly made their way through his eighteen year old brain and he eventually came to a conclusion. "Drinking this stuff makes my dick bigger! This is awesome and can't possibly backfire! I wonder if it makes me cum more?"

Determined to test his theory, he rushed back up to his room faster than a tornado and fired up the internet to watch his favorite adult content. Four hours later he was fully satisfied with his amatour science and the carpet under his desk was wetter than the beach after high tide. His laptop had also acquired several pieces of malware, but that's neither here nor there.

Riley drifted off to sleep early in the day with thoughts of a gigantic dick that would shock his friends in the football showers and make every cheerleader irresistibly attracted to him. In his mind, life after quarantine was going to be awesome.

However, Riley wasn't prepared for the exact changes that would greet his eyes the next morning. To his dismay it wasn't a monster dick that initially greeted his eyes, but a pair of monster tits that blocked his vision below his chest! They were almost like two basketballs, perfectly rounded and perky in a way that defied gravity and physics.

"Fuck!" He swore in shock and horror. "Fuck!" It was all he could think to utter for several minutes before he got tired of saying that word, as satisfying as it was to say. He then felt underneath his chest, a place nearly out of sight for him without some awkward contortion. To his great relief and satisfaction, he felt his cock was still there and bigger than ever.

With unbalanced movements, he moved to his desk and pulled out a measuring ruler to find out just how big he now was. A warm glow of happiness, and not a small amount of libido, suppressed his panic over his boobs when he found that his manly dick was a whopping 11 inches! Barely bigger than his sister by an inch, but still bigger and thicker than he was before. Never again would his sister snicker at the size of his willy. He'd be the one offering pity fucks now!

Wait. No he wouldn't. He wasn't one for taking it up the ass.

After taking care of his very manly morning wood, he wandered downstairs to get some breakfast and grow his dick some more. But instead of having the ground floor to himself like on the previous day, he found his aunt and sister busy going to pound town.

"Come on, Aunt Brooks!" Cali grumbled nonchalantly even as her pussy was watering the carpeting. "I thought it would be funny."

"Shoving the alarm clock up my ass and then repeatedly spanking me to turn it off wasn't funny. Do you know what could have happened if I hadn't been able to pull it out?"

Once again, the matriarchal figure was disciplining her niece and taking care of her own sexual desires, a two for one deal. The two of them looked just as arousing as before, and Riley found his hands drawn to the familiar spots on his groin. But to his surprise, he also found that his hands were moving to gratify his new tits.

It was quite a new sensation coming from his expanded chest. The pleasure emanating from his puffy nipples sent shockwaves through his still relatively masculine body, boobs notwithstanding.

Less than ten minutes later he found himself orgasming due to the combined self pleasuring and the sight of his family getting fucked. Unfortunately, his new upper body left him imbalanced and he stumbled into full view of the futa copulaters.

"Dude, what the fuck." Cali looked over at her brother in surprise at the sudden thump.

"Language!"

The nineteen year old futa teen grimaced as her aunt drove especially deep in her pussy in a way of reprimand and glanced back at her brother. "Are those tits? Did you grow tits from the virus?"

Cali snickered before launching into a barrage of teasing. "OMG, this is hilarious! You gonna need to go bra shopping later? I'll bet you'll look great with a cute lacy bra that will drive the boys nuts. Oh wait, if you grope yourself, does that count as sexual harassment?"

When even Aunt Brooks began joining in on the laughter and teasing, Riley chose the better part of valor and beat a hasty retreat back to his room. He'd wait until they were done before going to get something to eat and try other methods to grow his dick.

It turned out to be a full day before he had the nerve to come out of his room again. Not because of the fear of teasing, but because he was trying to get his cock to grow bigger. Big enough that no one would notice his mammoth mammaries. But all his attempts, and there were many, were in vain. None of the online tips helped him.

Eventually he was forced to come down to the fridge to drink more of his sister's milk to both sate his hunger and make his dick bigger.

However, he was thwarted by the fact that the fridge was completely bare and empty. A desert has more life and sustenance in it.

"Fuck. Now what?" A rumbling in his stomach emphasized his hunger. But whatever ingredients that had been there a couple days ago were now gone, and even if there had been something there, he still had no clue how to cook anything more than cereal.

When he ran down his limited list of options, he eventually realized there was only one choice. He had to get breakfast straight from the source.

Knock. Knock.

Riley hesitantly knocked at the door to his sister's room. It was one of the very rare times she was in said room and was alone. Apparently their aunt was required for a remote meeting that Cali absolutely couldn't listen to from under their aunt's desk.

"Come in." Cali's voice was a bit strained. It turned out it was because she had some hardcore porn playing on the TV and was idly stroking her ten inch dick. "Whoa, did your tits get bigger, bro? Come to me for bras? Wait, you're fucking bigger than me? Fuck!"

"I don't need bras, Cali." Riley corrected. "I'm fucking starving and the fridge is empty."

"So? What do you want me to do? I'm broke and can't afford to order groceries."

"Can you fill this up?" The eighteen year old held out the empty milk jug. "Please. I'm hungry, and I really want my cock to get bigger. Have you seen what's online?" He gestured towards the futa porn on the TV. "When we get back, I don't want to have the smallest dick in school."

The nineteen year old futa glared at her younger brother, specifically at his ginormous tits. She groped her own E cup tits as if comparing the two and she frowned when she realized her own breasts were now smaller than her brother's.

"Fill it yourself." She said, "You don't need me to do it."

"Please! My tits will probably go away once this thing is cured. But this is my chance to get a dick big enough to make my college life awesome." He gave several more reasons that ranged from ridiculous to laughable, but the campaign of annoyance paid off.

"Fine." Before Riley could celebrate, Cali added a stipulation. "But if you want my milk, then you'll have to drink it straight from the source."

She squeezed at an overfull breast, and an ounce or so of fresh milk spurted from her pink nipple. Below that on her body, a spurt of pre-cum erupted from her 10 inch cock.

"Seriously?"

"Seriously. If you want it bad enough, you'll do it." She then turned up the volume on the TV and focused on the porn on screen. As if this was no longer any of her concern.

Riley struggled to come to a decision for several minutes. His hunger, horniness, and brotherly separation tried to determine the correct course of action.

Eventually his stomach won the battle and he got onto his sister's bed to get his breakfast. This wasn't his first encounter with boobs, but it was his first time touching his sister's boobs and most certainly his first time touching boobs with the intention of getting a meal.

"Hey, not so rough." Cali complained.

"Don't blame me." Riley replied, "I've got no fucking clue how to get food out of these things. Oh wait!"

His troubles vanished as he figured out how to get milk to flow from his sister's giant breasts. He guzzled down the liquid as if there was no tomorrow and before either of them knew what was happening, half a gallon had been drunk by the hungry boy.

It became clear after the quarantine that Cali's Futa Quirk was excess lactation, that was how she was able to supply her starving brother. Not the most unique ability, but she learned to make the most of it when she got a good job at a milkshake shop.

"Hmm?" Riley broke off from his drinking marathon when something poked at his bare asshole. It occurred to him that he had completely forgotten to put on pants when he exited his room.

"Hey, champ." Aunt Brooks greeted her nephew with a grin. "I heard you liked drinking my cum. Since your mouth is full right now, I'm gonna give you a cum enema." Riley was about to give an emphatic refusal, he wasn't gay and he didn't want anything in his ass! But his protests died unspoken when his aunt continued. "If just drinking my cum gave you a bigger dick, just think how big your dick will get if your body takes my cum straight from the source."

Whether Aunt Brooks was guessing Riley's motivations or had checked his browser history was unknown. All that mattered was she knew the magic words.

Riley gave a silent nod and braced for his aunt's 15 inch cock to enter his ass. She lubed her cock liberally before poking her large phallus into her nephew's virgin ass.

"Fuck!" Riley muttered, a swear echoed by his aunt.

Inch by inch vanished into the eighteen year old's black hole. He orgasmed at least once during the initial penetration, but thanks to the changes wrought by the futa virus he remained harder than stone.

"Damn." Aunt Brooks said as she neared getting her entire length inside. "I always thought you had a cute butt, even before the virus. Even cuter than your sister's ass if I'm being honest."

"Aunt Brooks!" Cali whined, "Why would a boy's butt be cuter than mine? Are you serious? Look at this. What guy could have a cuter ass than this?"

"Several." The milf responded. "I could name them, but you'd just get jealous. Don't worry though, you just have what guys call a fuckable ass. Why do you think I'm always fucking it?"

The aunt and niece bickered for a few minutes as Aunt Brooks began thrusting into Riley's tender ass. Cali brought the argument to an end when she realized that she was the only one not getting sexually pleasured.

"Don't use his mouth, Cali." Aunt Brooks cautioned, "He's not ready for that and might end up biting it off."

"But... But... Fine. I'm fucking your ass then." She then circled around her aunt and then inserted her ten inch cock into her aunt's milf-ish ass. The resulting fuck session was rather chaotic and never synced, Riley was inexperienced, Aunt Brooks was patient, and Cali was pissed at not being the best in the room.

Despite all this, they all came to orgasm. Riley cummed first, a climactic bliss from the new experiences and his anticipation of being the biggest guy in the showers. Cali let her load out next, her jerky movements bringing her to an unsatisfying payoff. Finally Aunt Brooks unleashed the flood of jizz from her balls, filling Riley's ass to near overflowing.

At this point, Riley passed out. Whether it was from the overstimulation of his hitherto unused prostate gland or the knowledge that his anal virginity was now gone, no one can say. But seeing this, Aunt Brooks took Cali to her room to conclude the fuck session that would last until the next day.

When Riley woke the next morning, he, of course, groaned about the soreness of his ass. "Oof. My ass." But his butt-hurtness vanished when he remembered what it was all for.

He felt below his giant breasts, inching his way along his six pack abs until he met his dong. Even without measuring, he could tell it was bigger, more virile, and would absolutely draw all the girls when quarantine lifted.

But even as he rejoiced in his new gains and felt a spike of terror. There, just beneath his enlarged testicles, was the unmistakable feel of a pussy. A female pussy on his manly body. Actually, for all intents and purposes, his body was no longer manly. He was unmistakably a futa without any external distinction from his aunt, sister, and all of the infected formerly female population of the world.

"Fuck me! Fuck this! Fuck it all!" He swore. Riley got up and began pacing in nervous frustration. "Why? Just why? Why the fuck did I chase after a big dick and drink my sister's milk and aunt's cum? Who could've seen this backfire on me?"

The bouncing of his oversized tits eventually made him horny enough to realize he still had to deal with his morning wood. Measuring it, he found that it was now 16 inches. Just big enough to give himself a tit job, not that he took joy in the fact that he had tits to do the job.

His distress at being reminded that he had tits brought to mind that he now had a pussy, and despite the steel rod sticking out from his groin, he was now in no mood to take care of it. He stumbled downstairs to find some form of distraction. Maybe his book of superheroes would be enough to help.

Down in the living room, he found his aunt. She was chilling on the couch nude while watching the news. Her 15 inch cock was laying flaccid over her leg like a wet towel.

"Where's Cali?" Riley asked, trying not to ogle the member that had penetrated his ass the previous night.

"I wore her out last night so she's in bed. It's the weekend, so I'm letting her rest for a bit." Aunt Brooks patted the couch next to her, inviting Riley to sit there. Lacking a reason to refuse, and not wanting to arouse suspicion in his aunt that he now had a pussy to fuck, he sat down. The lustful scent of his aunt, freshly showered with a hint of sex, made Riley's cock drip with precum.

On the news was an important looking figure who was talking about the ARK Objective, a large-scale building project that was aiming to protect the human genome for the foreseeable future. A few concept images of something from a zombie film flashed on the screen along with some drone footage of the completed portions, filled with normal boring uninfected people.

"That looks really boring." Aunt Brooks commented. "Or at least it does now. After getting to have sex with this body all the time for the past few weeks, I can't imagine going back to what society calls normal." She flipped the channel to a different news channel where an infected dorm hall was in the middle of a massive futa orgy. "Hey look! There's your future school. You are going to have a blast when in person classes open back up."

Riley wasn't sure how he felt about his brand new pussy starting to moisten when he witnessed the forest of cocks in action. But he assured himself of his manliness by glancing down at his 16 inch manhood, the accompanying boobs notwithstanding.

"Frick." Aunt Brooks muttered, her own futa cock starting to stiffen at the continued explicit porn that was passing as news. "I just finished taking care of this and I really don't feel like cleaning up another mess down here." She glanced over at her nephew, specifically his very fuckable ass. "Say, do you want to sit on my lap? You seemed to really like it last night."

"..." Riley considered for a minute, his rear end clenching instinctively after a lifetime of denying any potential 'gayness' to his bros. But even as he drew in a breath to refuse, he remembered how fucking good it felt. "Fine. But just my ass. I may have boobs, but I don't have a pussy. I definitely don't have a pussy."

"I never said you did?" The milf raised a skeptical eyebrow, but she was too horny to think it through. She guided the barely male, teen boy onto her needy member. Aunt Brooks let out a relieved sigh as she felt Riley's ass clamp down on her girthy cock with a tightness of a nearly virginal butt. Riley shuddered in pleasure.

Several minutes passed with the only movement being Aunt Brooks changing the channel a few times as bland nonsexual ads came on the TV. Advertising agencies were still subject to all those pesky nudity laws that the news was able to get around. But eventually Riley was forced to move, as if by instinct. He pressed his feet into the carpet that was crusty from weeks worth of familial cum and rose up on his aunt's 15 inch phallus. He slipped on a damp patch and slammed back down to the hilt.

"Eep!" Riley squeaked in a mix of pain and pleasure that caused him to orgasm. His futa-fied balls jetting out a fountain of jizz onto the floor and staining the coffee table.

"Seriously? I put you on my ass so I wouldn't have to clean up." Aunt Brooks grabbed her nephew's ass, her hands not even making a dent on the firm perky posterior. "Sheesh. Since there's already a mess, I'm going to have some fun and fuck you like I fuck your sister. Too bad you don't have a pussy for me to fuck."

"Yep. I definitely don't have a pussy to fuck. No need to check." If Aunt Brooks wasn't intent on pounding Riley's ass into oblivion then she normally would have been smart enough to check. But the situation being what it was, she was solely focused on fucking.

What followed was half an hour of intense sex that had Riley seeing stars. Aunt Brooks unloaded at least two loads of her futa cum into the teens gut and seemed intent on not stopping for several hours.

It was around this time that Cali woke up and wandered into the living room.

"Oh, good morning sleepyhead." Aunt Brooks didn't pause the pounding for a millisecond as she greeted her nineteen year old niece. "I thought you'd be asleep for longer after you completely emptied your balls into me last night."

"I couldn't sleep." Cali grumbled. "I didn't know my brother was such a loud lover. I'd love to see him try making out in Professor Boring's class. He'd probably annoy the college shareholders; he's so loud."

"I'm- not- that- loud." The pauses in between each of Riley's words was caused by him making sexual moans that were of a surprising decibel level and unspellable pleasure.

Cali rolled her eyes. "Have your tits gotten bigger, bro?" She fondled the male/futa breasts that bounced like trampolines as Aunt Brooks vigorously kept pounding like a horny jackhammer. "Geeze. I'm pretty sure they're bigger than mine. Maybe I should start drinking more of my milk."

"Don't forget my cum." Aunt Brooks joked with a grin. "And taking it in the pussy doesn't count."

Again, the teenage eye roll. "Y'know. All this milking may have started up my maternal instinct. Do you wanna drink some more of your sister's tittie milk, bro?" She offered up her E cup breasts to her brother, her hands sunk into her oversized dairy factories but sprung back due to the extreme perkiness of her boobs.

Never one to turn down a free drink, Riley latched onto his sister's tits and began gulping down the white liquid as fast as he could. He hugged her close, their sibling cocks rubbing against each other between their double pair of tits and lubricated by a surprising amount of pre-cum.

"Fuck this feels good." Cali muttered as she let her hands roam over her own and her brother's bodies.

"Language- Fuck!" Aunt Brooks attempted to enforce her house's no swearing rules, only to be forced to violate her own rules by a sudden orgasm that dumped another load of cum into her nephew's ass.

"It's too bad you don't have a pussy, Riley." Cali commented as she rubbed against her brother. "This is fun and all, but there's nothing better than sticking my dick in a dripping wet pussy. Right, Aunt Brooks?"

Even as she grumbled, Cali's hands moved to caress her brother's balls. However, her long lady-like fingers brushed against her brother's new vagina. She dismissed it at first, but at the second brush with the warm entrance she dropped down to examine what she felt.

"What the fuck, Bro!" Cali yelled out. "How long have you had this? And how long were you planning on hiding this?"

"Stop- shouting, sis." Riley's speech was still punctuated by the powerful thrusts from his aunt. "It- showed- up- this- morning. I- wasn't- hiding it-"

"Whatever." She cut her brother's stuttered excuses off before they could start. "I'm fucking this. Prepare to get double teamed, bro!"

The older sister shoved a leaking tit into her brother's protesting mouth before lining up her 10 inch cock and plunging it inside. Riley's only remaining virginity was gone within hours of him obtaining it.

If Riley's mouth hadn't been full of sister tit, he might have yelled a mix of profanity and ecstasy. The initial sensations only lasted a moment, before he was in a euphoria of tits in front and behind him. Two beautiful and sexy women were fucking him. A few weeks ago, the fact that it was his aunt and older sister copulating with him, not to mention with giant futa cocks, would have horrified him. But now he just wallowed in the sensations and ejaculated between his breasts, making a slip and slide effect between the bodies of the siblings.

This continued for over an hour. Perhaps longer. Over a gallon of spunk soaked into the floor and couch from all three of them. Their futa balls endlessly churning out warm futa jizz and their transformed bodies ceaselessly fucking with the unstoppability of a grandfather clock.

But all good things have to come to an end. Sometime around mid-afternoon, all three of them were separated and panting on the couch in total exhaustion. All three cocks were completely flaccid, all six breasts heaved for breath, and the air reeked of sex and sweat.

"Fuck." Cali swore once she had recovered enough to speak again. "That was awesome, Riley. Wait, should I still call you Riley? I mean, you've got tits and a pussy now... Should we brainstorm a new girl name for you?"

"No." Aunt Brooks waved the suggestion away like it was an annoying fly. "Riley works for both boys and girls. Believe me when I tell you, getting your name changed is pure hell and you don't want to do it. So Riley stays Riley."

"Yeah." Riley added, "I'm not fucking changing my name. Besides, I'm not a girl. I'm still a guy with a few extra bits."

"Ha!" Cali scoffed, she then fiercely poked her brother's gigantic round breasts. "That's a lot more than a bit. Seriously though, how the fuck are they that big?"

"I don't know? An effect of the virus? How are you making that much milk in your boobs?" He returned the poking, and his sister's tits leaked enough milk to make a cow jealous.

The mutual stimulation caused the sibling's virile cocks to stiffen and rise again, despite the exhaustive fucking they had just undergone. Aunt Brooks noticed this and got up from the couch. "I've got work to do before Monday. Be nice to each other, kids." She then went upstairs while the brother sister pair initiated another sex session.

A month or two later Aunt Brooks came downstairs with exciting news, her milf tits and futa cock bouncing hypnotically. "The quarantine is over!" She flipped on the TV with a flick of the remote. The chairwoman of the UN was giving a speech telling the world that the last uninfected person was safe in an ARK and quarantines and public nudity laws were no longer to be enforced. Humanity was free to go back out without restrictions.

"Fucking finally!" Cali swore with her back on the couch and legs in the air, her middle was distended from her brother's giant cock in her pussy. "Now someone else can take this monster dick every morning."

"If you didn't want it, sis, then you wouldn't jump on my morning wood every day." There were only trace hints of Riley's manliness left in his form. If you looked closely, you could see the remains of an Adam's apple and a chiseled jaw, but the rest of his body was unmistakably futa and you'd be hard pressed to say he was once/is a man. His breasts were large and bouncy, his ass was thick and fuckable, and there was no one who'd swipe left on his profile.

"Kids, be nice." Aunt Brooks casually offered her girthy cock for Cali to suck. "More importantly, you need to pack up."

"Pack up?" Riley asked as he groped his aunt's breast.

"Pack up. It's the middle of summer now so school's out. Your mom is coming over to pick you up until school starts back up in the fall. Hopefully your asses are ready for something big. From the pictures your mom has sent me, she's packing a monster now!"

Once again, thank you for reading this story! My heart was warmed by the comments from my last story. Since I got so many, I resolved to try to post a story a month. Speaking of warm response, I was going to beg for an even 350 followers just to boost my ego, but I got up to that while I was writing this. Hooray! As always, if you have ideas/suggestions/writing critiques, add a comment. The next story is the suggestion from Juan_p3p3. I'm already brainstorming it and it should be awesome! Happy St. Patrick's Day, Y'all!
