"Come on! If we have to watch anything please don't put that on!" Edward's plaintive pleas were unanswered as the rest of his sisters tried to figure out what to watch on the family television.
Thanks to the Futa Virus, the six siblings were all stuck together in quarantine, their parents happened to be quarantined elsewhere for work reasons, and someone had forgotten to pay the internet bill leaving the living room tv and whatever cable television provided as the only source of entertainment for the six people in the house. They were stuck arguing over control of the remote.
For those unaware of what the Futa Virus is, the Futa Virus was the result of a Florida biolab mistake that combined COVID with a secret experimental mutogenic agent.
The symptoms of the Futa virus varied depending on the infected's gender. Females infected by the virus would always grow penises of varying sizes, other symptoms included, but were not limited to, increased libido, enhanced breast size, exceptional stamina, and, informally at least, a gradual loss of morality and decency.
Males infected by the virus had their own way of exhibiting symptoms. The majority of those affected would pass on to their preferred afterlife. Those who survived would gain the enhanced sexual performance that their futa counterparts received, but those who gained only that were the rare exception. More commonly, men infected by the Futa Virus would transform into full on futas. Genetic testing later on could only find faint traces of their previous masculinity, well, aside from the massive futa cocks they now possessed.
Blame couldn't be placed with any particular sibling, not for lack of trying, but a few days ago the Zakar progeny had become infected and now displayed all the symptoms of the disease. Cocks, tits, libido enhancement, ect. Now that their bodies had stabilized in their new forms, everyone was out of their rooms and inspecting everyone else.
Edward was the only man in the house at 13 years old, and despite surviving the Futa Virus, he wasn't exactly happy. He only received a slightly larger cock at ten inches and maybe a bit more of a sex drive than before. However, his main concern at the moment was preventing his sisters from putting on a chick flick.
At five to one though, Edward lost the battle. Caryn, the youngest of the bunch at barely 12 years old, was entrusted with the remote to put on a rerun of Love Island. She sat close to the TV with her legs crossed Indian style while everyone else settled into their favorite spots. By the time the intro was playing, the family was nestled into their preferred couch and position.
Since his dad wasn't home, Edward stole his dad's couch spot. Before he could stretch his legs though, his oldest sister, Katie, sat down in their mom's seat. She was the responsible older sister type, at 20 years old she was a bit more mature than the rest of the family in the house. The virus' effect on her was mildly obvious from the thirteen inch bulge in her crotch, but significantly more apparent from her J cup tits that stretched her tank top to its limits.
When the first guy appeared on the screen, shirtless and gyrating, the reaction was immediate on the females watching. Edward attempted to cringe and move away, but he found his movements suddenly restricted as Katie wrapped him in a hug and began using his warm body as a hug pillow as she had ever since they were little kids. It wasn't unpleasant, at first, the oversized tits pressing into him was quite enjoyable to his 13 year old body, but as soon as he felt her fifteen inch cock pressing against his back he tried to escape like a ninja.
"Quit squirming." Katie muttered as she squeezed tighter and humped her cock against her brother's back. "Ooh, that feels good."
That was all Edward needed to break free from the ickiness. From his side of the couch, he saw precum leaking through her shirt from how much he had rubbed against the futa cock.
"Aww." The oldest sister made a pouting face before going back to watching the hunk on the screen. Despite disliking the show, Edward found his eyes drawn to it when the scene changed to display a bikini clad woman giving her introduction, before he knew it, his ten inch cock was pitching a tent like a scout.
His attention was suddenly yanked away by the sensation of a feminine hand snaking into his pants and freeing his member. Said hand belonged to Katie, who had sidled closer to him while he was distracted. Her own fifteen inch cock was out in the open and she gave it a meaningful glance as she began stroking his dick. The siblings had always been close, and the non-verbal communication was enough to convey the eldest sister's meaning. She'd make him feel good if he did the same for her.
Edward hesitated for a moment. He'd only ever touched his own wang in the privacy of his bedroom, and didn't want to invite the jeering insults of his peers whenever the world opened up again. Katie did something with her fingers to the head of his cock that changed his mind instantly. With an inexperienced, but very eager, grip, he wrapped his hand around his sister's meat rod and began pumping it for all he was worth.
"Don't be so rough, Ed." Katie muttered, trying not to draw the attention of the other siblings as they watched the show. "Do it like this." She demonstrated on Edward's man meat how to properly do a hand job. "There, just like that. Ooh, you're good!"
For several minutes they half heartedly glanced at the Love Island protagonists while vigorously jacking each other off. It only took a bit of time for the orgasms to hit, and due to their surprising synchronicity, they blasted their spunk into the air at the same time with quiet moans that somehow went unnoticed by the rest of the family.
"Hey, sis. Do you want to go further?" Even though he had just cum, his ten inch rod was as hard as steel and ready for more. He slid a hand under his sister's shirt and tried reaching for a bra strap. That hand was removed by the gentle guidance of Katie.
"I don't think I'm quite ready for that, Eddie. But I think Bekah could use your dick." The pair glanced over at the second oldest sister. Bekah was 18 years old and an inveterate gamer who often made extra cash streaming. She had emerged from the Futa Virus with tits slightly smaller than Katie's at a still sizable G cup with a proportionately scaled up seventeen inch cock. It wasn't her cock or tits that drew the sibling's attention, it was that she was humping a couch pillow like her life depended on it.
Since Katie's advice to him had never been bad, Edward stuffed his dick back into his pants and shuffled over to Bekah's seat. The instant he sat next to her, she replaced the pillow with his leg, alerting him that her pussy was sopping wet, it was almost as if she had spilled something on her panties, except the spillage was coming from the inside.
"Whoa. Are you all right?" Edward asked his older sister.
"I'm fine. I'm fine." She replied in a hyper tone that indicated anything but being fine. "I'm just horny as hell and can't figure out what I need to get it out of my system. Have you seen the bulge on that guy? Woo!"
"Maybe you need something in your pussy?" Edward suggested as he slipped his dick out of his pants and let it poke his sister's back.
"Maybe." Bekah replied. "Maybe. Should we give it a test just to find out?"
Without so much as foreplay, the 18 year old whipped off her panties in a single fluid movement and jumped on Edward's cock like a pro. Just like that, the sibling boundaries had been crossed without a second thought being given except to satisfy their lust.
As expected of two humans infected by the Futa Virus, their libido was exceptional, even if their sexual skills were lacking. The two of them fucked like rabbits for the entire first episode of Love Island and their lurid moans were barely covered by the drama occuring on the TV. It was only when the opening credits started playing for the second episode did Bekah crash on the couch.
"No more, Ed." She panted. "I think I've had enough for now."
"But…" Edward still felt like an endless fuck machine with so much more energy left. He wondered for half a second if that was from the Futa Virus before diverting his thoughts on how to slip back into his sister's warm cum filled pussy.
"Maybe later, Ed. I think I need a nap now." She pulled a blanket from under the couch and promptly fell asleep.
Not having anything better to do, Edward looked around for another way to relieve his raging libido. His eyes honed in on his third oldest sister, Stacy. She was a blond boobied 16 year old cheerleader in high school and had the body to match. After her body was 'ravaged' by the Futa Virus, she now had gigantic M cup tits that sat like melons on her chest with only a thirteen inch cock decorating her perfect hourglass hips.
Stacy wasn't humping the chair or jacking off like her older sisters were, in fact, she was pretty much oblivious to the world as she scrolled through pictures on her phone. Edward, with undeserved confidence, felt that he could get his fill of pussy and boobs all in one.
"Is this spot taken?" He asked while standing next to her oversized chair, his ten inch cock almost in her face. She glanced derisively up at him.
"Cute. You've got even less rizz than the football players." Her harsh words aside, she scuttled to make room for her younger brother. Convinced he had a secret talent that the Futa Virus had unleashed, he made an unrestrained grab for the enormous knockers.
The cheerleader however, had more than enough experience with jocks trying to cop a feel and restrained him without effort. "Nice try, punk. If you want to touch these babies, you have to do something for me first."
"Whaa?" Edward couldn't believe this, but he soon came down from the cloud nine his time with Bekah had left him on. "Ok, what do you want?"
"Suck my dick for me. Not the lousy handjob you gave Katie, I want to be balls deep in your big mouth."
"... Is this revenge for me ratting you out to mom whenever you came home past curfew?"
"You better believe it, you rat. Now start sucking or get lost."
Edward unconsciously smacked his lips a few times as he glanced down at the thirteen inch fuck stick on his sister's crotch. Like the rest of Stacy's body, it was clean, petite, and pornstar worthy. He looked back and forth, weighing whether the tits were worth it or not.
Eventually, the boobies won the mental war and he sidled down the recliner until he was face to face with her rock hard thirteen inch cock. Edward took in the scent of her unused babymaker, it smelled surprisingly nice, not that he'd ever considered what futa genitalia smelled like before. A few minutes later, he performed a small taste test, like it was a weird fruit. It didn't make him gag, in fact he found it quite pleasant on the tongue. Soon he had the entire thing in his mouth and was trying to control his gag reflex like he had seen in porn online.
"Fuck, you're not half bad." Stacy commented. "The first time I swallowed cock I nearly threw up in the quarterback's crotch. He wasn't nearly as big as I am now."
Of course, Edward could make no response as his mouth was full of futa dick. He wondered though what had happened to the quarterback. Once the quarantine had lifted, they found out that Quarterback Dan had taken shelter in what he thought would be the best place in the world, a college cheer sorority, it ended up less than ideal when all the girls transformed into hyper futas who loved using his ass 27/7.
It only took five minutes for Stacy's facade of indifference to fade away as she grew closer and closer to orgasm. "Hoo. You're- You're pretty good. I think I'm gonna-" She grabbed the back of Edward's head and started controlling his movements. "I always hated when guys used to do this, but I think I can see why they did it. It feels so fucking good!"
Ten minutes later, during which Edward questioned how the heck he was still breathing with the large cock in his mouth, Stacy blew her load directly into her younger brother's waiting face hole. "Oh fuck. Oh fuuuuck!" She did her best to stifle her moans to not alert any other sibling who wasn't already aware of the sexy action going on.
Pump after pump went down Edward's throat until he had lost track of just how much cum Bekah had put out. Whatever the amount was, it was far beyond what any male could.
Just when he was starting to get a bit nauseous from the sheer quantity of fluids, the flow came to an end and he came up for air off the softening cock. "Phew!" He gasped. "So now can I touch your boobs as much as I want?"
"..." Stacy was in the midst of an orgasmic afterglow and simply nodded.
Not needing a second invite, Edward dove for the massive mammories and had his fill playing with the M cup tits. His enjoyment ended when the sounds of pool water splashing about on the show reminded him that he really could use a cup of water to wash out his mouth. Not that the flavor of his sister's cock was bad, but he just hadn't gotten used to it. Yet.
On his way to the kitchen, he passed by his only remaining older sister, Tara, who was barely a year older than him at 14 years old. Edward paused with reservations, the two siblings had never really gotten along despite being so close in age since he had been a standard kid growing up and she had leaned towards goth stuff. The reason for his momentary stop was that Tara seemed to be in distress, twitching and breathing sharply as she lay back on the couch with her eyes rolled up.
"Hey, Tara, are you ok?" Edward laid a tentative hand on his sister's pale skin. He noted that the futa virus hadn't done anything for her in the chest department, seeing as she barely tented her shirt with modest B cups.
"Fuck! I'm cumming!" Her shout was fortunately drowned out by a particularly obnoxious truck ad from the TV. Thick baby batter flowed from her elevated pant leg and onto the coffee table her long limbs rested on. Even with a belly full of cum, Edward instinctively licked his lips upon witnessing the spunk river running to the carpet. "Shit. Don't touch me so casually, jerk. I've been sensitive all day thanks to this fucking cock."
"How sensitive are you?" Edward asked, he had only lightly touched her shoulder, nothing that should have prompted her to orgasm.
"Fucking insanely. Maybe I just need to cum inside something… Or someone…" She gave him a look he did not like while biting her lip seductively. Edward traced the bulge on her pants leg with his eyes and immediately had the red alert klaxons ringing in his head. At an estimate, her dick was at minimum 25 inches and nearly as thick as a soda can. He didn't want that thing anywhere near him.
"Well, um, maybe I can get you something from the kitchen." Tara caught his wrist as he was about to flee.
"Wait!" She thought for a second. "If you let me fuck your ass, I'll let you fuck my girlfriends."
Edward thought for a moment. The male weakness for dom goths was just as strong in him as in most other men, and his sister's girlfriends, in their skimpy leather shirts and transparent fishnet leggings, had several prominent spots in his spank bank. It only took a moment perusing the terabytes of mental imagery and what they must look like now after the Futa Virus for him to cave.
"You better keep your promise on this." Edward grumbled as he turned his ass towards his big sis. "If you don't then- eep!"
His grumbles were cut off by Tara's fingers folded around a wet wipe and then tongue going the wrong way down his one way backdoor. She didn't need to lube up, since her gallon sized balls produced enough precum to run a slip and slide, and the goth girl slowly slid her 25 inch meat pole into her younger brother's ass.
Edward had never experimented with putting things up his rear end, years of middle and high school loudmouths had ingrained in him a firm conviction that anything about that area was 'totally gay'. Now those convictions were being shattered into oblivion by his goth sister's ass shattering futa cock. It was a mind altering sensation that he both really regretted and really loved at the same time. One thing was for certain, he would never be the same again.
"Ooh fuck! You're ass is so fucking tight!" A beer commercial blared its sales pitch to cover the noise of their fuckery.
Just like with Stacy, Edward couldn't reply. The shock to his nervous system was close to overwhelming him. Although if she could read his mind, she would have gotten the gibbering of a guy in orgasmic bliss and frantically trying to get the massively oversized foreign body out of his ass.
"I'm gonna cum again. Hope you don't mind if I cum in your ass." Edward felt the first jet of fertile baby batter smash into his abdomen from the inside like a firehose that just did not stop. Each of her orgasms merged into the next in a seamless repetition of ejaculation. He was startled to find that at some point he had begun climaxing along with her and was spraying his seed all over the room.
"Whoa. Now that's hot!" Stacy had looked away from her phone and happened to catch sight of the action. "Keep fucking him like that Tara!"
"Woohoo! Now that's what I like to see when I wake up." Bekah cheered as she threw off her blanket.
"Be careful, you two." Katie remarked. "Don't forget to take a break to hydrate."
All three of them had their cocks in their hands as they watched the show. The catcalling finally alerted the youngest member of the family. 12 year old Caryn. She had practically been a shoo in for the high school cheer team in a few years with her blond hair and perfect body, then the Futa Virus had basically inflated everything about her. Ginormous Q cup tits bounced and heaved as she sprung up from her spot to reveal a nineteen inch cock and a pair of balls the size of two liter soda bottles that appeared excessively massive on her preteen bodily frame.
"What the fuck is going on?" Caryn demanded in a tone that was a mix of worry, shock, and disbelief. "Tara, what are you doing with Eddie?"
"Isn't it obvious? I'm fucking him in the ass! I'm cumming in his fucking ass!" Tara tried being casual about it, but her grip on Edward's waist was iron as she thrust in and out. Caryn was much less blase about it.
"Eddie! Are you ok? Geeze, how big is Tara's cock that it's making such a huge bulge in your belly, wait, is all of that cum? Tara, give him a break."
"Fine. Just one… More… Fuck!" The goth ejaculated one final flood of baby batter into her little bro's ass before releasing him. Her monstrosity of a cock flopped over her leg once it was withdrawn and Caryn caught her older brother against her enormous tits.
"Eddie? Eddie! Are you ok after having that in your rear?"
"I think I'm ok?" Edward wasn't sure. The afternoon had been a wild collection of sexy twists and turns. If there was one thing he was certain of though, he needed a break.
"Hey, Eddie…" Caryn looked up at him pleadingly through her lashes. "Do you think I could fuck your ass? I'm not as big as Tara and will let you touch my boobs as much as you want."
Always a sucker for his cute little sister, Edward folded like a poker player with a pair of twos. "Just be gentle at first." He said.
Caryn caringly laid her older brother on the thoroughly cum soaked couch and lined up her nineteen inch cock with his tender bung hole. "I'm going inside, big bro." Inch by inch she moved her long rod into Edward's backdoor until she was balls deep. "Ooh! I feel so close with you, Eddie! This feels amazing."
Edward was having the time of his life under his sister's tits. The gargantuan boobs were like never ending squishy balls that felt amazing, not to mention Caryn's comparatively smaller cock was just right for his ass after the intense railing Tara had given it.
"Hey, do you think you could give me a hand?" Katie asked, her fifteen inch cock nearly poking Edward's eye out.
"Me too?" Bekah jumped behind him with her sopping wet pussy ready for him to do whatever with.
Being in a very good mood after seven minutes of boobie heaven, Edward moved his hands to jerk off Katie's cock and stimulate Bekah's pussy at the same time. Which was sort of like trying to pat your head and ruby your belly at the same time, but with a lot more sexy moans.
"Don't try to leave me out, jerk." Stacy hopped on Edward's chest, her thirteen inch cock landing on his face. "Time for round two." Now he was satisfying four futas all at once, which only left…
"What about me?" Tara grumbled, her twenty five inch ass destroyer twitching and almost ready for another go.
"Get lost, Tara. It's my turn." Caryn said firmly.
"No room here." Sacy replied from her perch.
"Nope! Too big." Katie and Bekah turned down their younger sister without a second thought.
"Hmph. I guess I've got no choice then. Consider this a one time deal since you let me cum in your ass." Edward was unable to see anything around Stacy's body, but he felt his ten inch cock being futa-handled into something. Whatever his cock was inside of was tighter than a pussy and had a much more unique texture.
"Woah." Caryn exclaimed. "Docking? That's pretty advanced."
"It's not so bad when your dick is as big as mine. You could probably do it too, but fuck! It's really tight! I think I'm gonna cum again." The flood of spunk ran down her twenty five inch rod like a tsunami and, even though a good amount of it spilled onto the carpet, an absurd amount made its way into Edward's average sized balls.
"Mrph!" Edward groaned as he felt his testes swell up, but he never paused his stimulating efforts with his other three sisters.
"I think I'm about to cum too." Stacy exclaimed. "Your mouth is just too good!"
"I'm cumming too." Katie said.
"Me too."
"Me three!"
"Should we cum together?" Katie asked.
"Fuck yes!" The chorus replied.
Then with an amount of sibling cooperation that most parents dream of, all five futa sisters orgasmed as one. Plastering the 19 year old boy with their cum and draining all their balls.
It took them almost an entire episode of Love Island for them to recuperate from their epic fuck session, and for Edward to get out of the shower after trying to clean up. By the time the opening credits rolled on episode six though, they were ready for more.
"Wait, why can't you fuck each other?" Edward asked in alarm as they all began moving in on him. "You've all got dicks, asses, and pussies. I don't have a pussy! Why not fuck someone with a pussy?"
His suggestion caused a pause, the five of them looked down at their crotches, then at each other, then back at him.
"Nah." Stacy dismissed the idea with a shrug. "I tried the whole kissing girls thing in the sorority hall. Not my thing."
"Same." Katie blushed as she recalled a memory.
"No one wants this inside them but you." Tara commented dryly.
"Your dick just feels right." Bekah said.
"No one but my big bro for me." Caryn exclaimed.
This was the start of Edwards' very busy quarantine. From morning till night he was engaged in some form of sexual activity, and, without him noticing for a while, the continued exposure and injection of futa cum into his body made him even sexier with a bigger cock and more powerful muscles for both pounding and being railed.
Everything was all fine and dandy for a couple months until one day Bekah came out of the bathroom holding something. "Everyone, I'm fucking pregnant!" Of course, the five futas glared at Edward, then they realized something and dashed for the bathroom all at once.
"I'm pregnant too!" Katie exclaimed in surprise.
"I've got big bro's baby in me!" Caryn squealed.
"Fucking one time I let the jerk nut in me." Stacy grumbled. "I should have kept him on my tits."
"I'm never going to live this down." Tara grumbled. "I'm going to fuck his ass so hard for this."
"Um." Edward wasn't sure what to do with the info that he was about to be a dad five times over with his sisters. "I don't suppose you can give me a break now that you're expecting?"
The answer was, of course, a hard no. A very firm, long, and veiny, no. One that left him covered in cum and his sisters temporarily sexually satisfied for the afternoon.
