Lab Accident 2 - Reproducible

(Warning: just like the first Lab Accident, here there be freakiness. Still, if you like my work, show your appreciation by buying a book!)

The iron gate creaked as Theresa swung it open, navigating Olivia's wheelchair up the steps to the front door of Dr. Hill's rowhouse. It was the middle of the day and civilian traffic was blessedly low, giving the girls a rare chance at a private moment outside.

Theresa did her best to ignore the stares, the mumbled comments and occasionally the screams, and generally just tried to go out as little as possible. She looked back at the massive, billowing skirt covering the second torso jutting out from where her buttocks should have been, curving down several feet behind her into a second pair of legs bent at the waist, like a human centaur.

She could feel the pendulous swaying of the four breasts on her lower torso as she walked, swinging like grotesque udders, and the gelatinous bobbing of the basketball-sized rack that adorned her chest. Olivia had drained them before the pair left, but in a few hours all six of her breasts would be tight, swollen and aching with milk.

Olivia had an easier time hiding her mutated form but found herself more restricted. The wheelchair hid the fact that she no longer had legs, but rather a long, fleshy, serpentine tail. Baggy shirts and sweaters hid three large breasts and a second pair of arms, which were often used simply to hold down the two long cocks which sprouted from above her pussy.

"So why do you think Dr. Hill messaged us?" Theresa was awkwardly trying to manoeuvre her arms around her jiggling bust, which bounced up and down AND left to right with each step, dragging her thick nipples against the front of her dress.

"Not sure, but it sounded important." Olivia was sweating, not from the heat, but from her libido. Theresa had problems with her erogenous zones, but there was literally no part of Olivia's body that wasn't almost painfully sensitive to stimulation, and she spent most of the day on a slow burn of arousal. "Maybe he- err, she, found a way to cure us?"

They rang the doorbell. There was a brief commotion of noise from inside, a pause, and then the door opened a crack. Theresa coughed. "Dr. Hill? It's us."

"Olivia? Theresa? Is that you? Come in, quickly."

The two girls were immediately taken back as they entered the front hallway by two things; the dishevelled, bizarre appearance of their former supervisor, and the thick gobs of drying and fresh cum that covered the house.

The explosion had transformed Dr. Thomas Hill from a late-twenties man into a tiny, adorable girl who, if not for her absurd figure, would not have looked more than sixteen. Enormous breasts curved from her slim chest, and her wasp waist curved out into a massive, heart-shaped ass. Her pretty face was slightly marred by deep bags under her eyes, but moreso than that the erotic effect of her figure was marred by her more bizarre mutations.

A foot of cock swung limply from her groin, slapping into an oddly-shaped scrotum that, on closer inspection, held eight grapefruit-sized testicles, impeding her walking as it hung nearly to her knees. The girls knew that erect, her penis stood a proud three feet long, and so thick two hands couldn't hope to encircle it.

Two more dicks, these ones erect, sprouted from her breasts where her nipples should be, bobbing eight inches away from the quivering mounds. Her hands were moving in slow, deliberate motions, jerking them off even as she led the girls into the lounge room. The furniture in there was caked in even more cum, and the girls very carefully navigated through. Dr. Hill plopped down into a puddle on the couch without a second thought, tugging at her tit-cocks shamelessly.

"Okay, I don't have a lot of time to talk, so first thing: It's Tammy now, for the moment. Please excuse the mess; I haven't had time to clean up." She lay back, jacking her tits off faster, moaning as her breastflesh jiggled. "I've-mmm-figured out a way that we'll aah!- be able to go back out in public again."

The girls perked up, the excitement of that news cutting through the fog of lust building in their brains watching the doctor pleasure herself. "You found a cure!?"

She sighed slightly, inbetween moans. "Noooh aah, nooo. We're ssstuck like this. But I had a'other idea..." She rolled her eyes as her speech started to slur. "Touh' I 'ad mo' tie' dan da'..."

The girls watched in rapt attention as Tammy's tongue poked out of her mouth, unmistakably a half-flaccid penis, and started to swell before their eyes until it was as long and thick as her tit-cocks, stretching out her tiny, pretty lips.

Olivia couldn't resist any more, slithering off the chair, a pair of arms peeling off her shirt to reveal the twin foot-and-a-half lengths of her cocks, jacking one with one hand and rubbing her juicing pussy with the other.

Reaching Tammy, she curled out her forked tongue and wrapped it around the doctor's tongue-cock, tugging it in strong, slow strokes. Her top pair of arms pressed her rack together as Tammy's tit-cocks nestled in her dual cleavage and her bottom pair stroked up and down the length of her twitching dicks.

"Thith feelth good, Doctor," she lisped, her slitted eyes twinkling as she grinned, "but Theretha ith going to go mad if all thee can do is watth..."

Theresa was panting and moaning, rubbing her front pussy desperately. She was utterly dependent on Olivia for all of her relief, as she could neither milk her hanging breasts nor reach her rear pussy. She responded to the offer with a delighted moan, Olivia slithering back to let Theresa straddle the doctor's lap.

Tammy's main cock started to swell as Theresa pressed the heat of her pussy against it, and she guided it between her titanic tits as it grew to its full height. "Give me a hand here, Tammy, squish them together..."

Tammy let a muffled moan out through the tight seal of her lips as she began to maul Theresa's bounteous breastflesh. Tammy's tits lay atop Theresa's, and she reached for the nipples and began to stroke them even as she ducked her head in to take Tammy's tongue-cock down her throat.

Olivia slithered underneath Theresa, sliding one cock into her rear pussy and the other between her swinging lower tits, grabbing them and squeezing them, giving a contented purr as hot milk dripped onto her body.

The trio rutted, groaning and sweaty, thrusting and rubbing and squeezing until Tammy started to whine, desperately trying to be heard through the obstruction in her mouth. Her eyes rolled back in her head as she started to cum from every single cock in her body, her ballsack tightening up and her muscles straining. Her tits jiggled and the back of her throat pulsed as those three cocks unleashed their payload, but her main cock just tightened, straining, her stomach muscles spasming until it finally erupted in a fountain of thick spunk.

It didn't take long for the other two to join her, and soon the girls lay panting in a pile of cum-covered, heaving flesh. Tammy rolled over, staring at the ceiling with wide eyes. "That was amazing. I haven't been able to satisfy myself since the accident."

Olivia giggled, turning over and propping herself up on her elbows to look at Tammy. "So, what did you want to tell us? If you haven't found a cure, what have you found?"

"An idea, I guess. I mean, we can't function properly because we're not normal. There's no way for us to change back, so if we change what's normal..."

The two girls stared at her for a moment. Olivia drew back on her tail. "Doct- Tammy, are you suggesting what I think? You want to do this to other people?"

Tammy immediately went on the defensive, stuttering. "Well I- I just, it's, you know, I mean, it's not all bad, right, it feels good, it's just-"

Tammy reached into a box on the table, drawing out what looked like two remote controls. "I managed to miniaturise the cold fusion tech from my reactor – fortunately bursts of energy are a lot easier to generate than a sustained reaction, even when you're designing it ten minutes at a time with an erection. Or four. One click of this and whoever's in front of it should get a burst of the same radiation that transformed us."

Olivia sniffed, scraping cum off of her tail and coiling back into the wheelchair. "Tammy, that's sick. You're sick. I know living like this sucks, but what you're proposing is- it's rape! I think we're done here."

"Think about it!" Tammy was almost screaming now, pleading. "A whole city like us! You wouldn't have to go outside and feel like a freak!"

Olivia set herself back up in the chair, but noticed that Theresa had sat down on the couch, her front legs kneeling. "Theresa? You're not coming? You think she's right?"

Theresa looked down sadly at her absurd chest, shifting her rear awkwardly as she tried to get comfortable. "I'm tired of being called a freak, and the screams and stuff. She is right – it feels good, most of the time, it just sucks not being normal."

Olivia looked back and forth between the two, and sniffed. "Fine. I'll make my own way home." Tammy sighed.

"I'll take you down the steps, if that's what you really want." Olivia didn't notice Tammy slip something into the bag on the back of her chair before she left.

Theresa walked dejectedly back into the house after watching her friend start to wheel herself home. Tammy was already on the phone.

"...and a large pepperoni, extra cheese. Yeah, we'll get a soda too, thanks. See you." She turned back around to Theresa. "Okay, so we should have a test subject in about fifteen."

Theresa sat herself down again, wincing as her lower breasts pressed into the floor – they were already starting to fill up again and become uncomfortable. "The pizza guy?"

Tammy nodded. "Or girl, I'm not picky and I'd like to get a sample of a couple of each, see what sort of transformations this burst of energy can cause." She sat down next to the humantaur's flank, rearranging her legs around her bloated scrotum and thick cock. "So what's the first thing you're going to do once you can walk around outside properly again? I'm going to go to a restaurant, I think."

Theresa sighed, hefting her breasts to check their weight, judging how long it would be until they needed milking. "I don't know about this, Tammy. It seems wrong to inflict this sort of inconvenience on someone else."

"It won't be inconvenient when everyone else feels the same way. Imagine – people will just be able to masturbate in public, because everyone's cool with the fact that our bodies need sex. Nobody will think we're freaks. Hell, people will be happier when we're more focused on fucking than fighting."

Theresa nodded, uneasily. The pair sat and made small talk for a little while, Tammy enjoying the reprieve from the needs of her body for a short while. Her main cock was just starting to rally back when the doorbell rang.

Elise sighed, shuffling her feet and staring at the porch roof holding the pizza bag. She hated driving duty but at least the tips made up for it. She heard the door open and dropped her head, putting on her best glassy smile, only to be greeted with a flash of blue light.

Her legs went weak, and she nearly dropped the pizza until it was taken from her hands, a blurry shape leading her into the hall and closing the door behind her. Her body was heating up, her wobbly legs on fire and her sizeable breasts almost as hot. She was sat down in a chair, blinking away the spirals in her vision until she could make out the two people above her.

She shrank back when they swam into focus. The small, cute girl in front of her was peering at her over what was unmistakeably a huge penis sticking out of her mouth, but before she could react further she felt a tight, squirming sensation from between her legs. Her shorts were feeling constrictive, the crotch pressing against her tightly and growing worse with every passing moment.

There was a sickening, sucking feeling, and ignoring where she was she pulled her shorts down, screaming at the sight that greeted her. Her legs had closed together at the tops of her thighs, and her pussy was nowhere to be seen. The join in her legs rapidly progressed down, pushing the now-loose shorts down as they fused together until all that was left of her legs and feet was a fleshy stalk.

It thickened up until it was the same width the whole way down, what had been her feet beginning to swell further, pressure building up, along with more pressure in her chest. She felt a gurgle through her breasts, watching them rise like bread dough under her shirt.

Screaming, she pitched forward, suddenly finding her legs not only fused together but unresponsive, landing on her stomach and watching as her cleavage spread out gelatinously underneath her as she swelled. Pangs of pain came from what had been her legs, along with a sickening creeping feeling down the length like something was pushing its way down.

She heaved herself over, swinging her breasts to get momentum, and moaned as the impact of the fleshy mounds against the carpet sent a buzz of pleasure all through her body. Another rocketed through her as she curled up, dragging her leg-trunk across the carpet until she could sit up, her back propped against the wall, finally able to see over her breasts which now spread across her lap, her shirt long having given up.

The sight made her jaw drop. From the waist down her legs had transformed into an enormous penis, the head starting to swell out of its foreskin, gripping her whole body with paralysing sensation as it rubbed and grinded against the carpet pile.

She panted, her head swimming as half her body tightened up, her legs now a rigid trunk of cock that pulsed and throbbed like a regular size one with her beach-ball sized breasts resting on top of the base like a bizarre scrotum, topped with tiny nipples that hadn't grown at all with her tits.

It was pulsing even harder now, pulling her around with each throb and making her steady herself, straining to hold up her bloated bulk with just her arms. It was on fire, new muscles up her back and stomach flexing with her impending orgasm. Theresa and Tammy looked on in shock as their new creation started to cum.

Olivia wheeled herself back into the front foyer of their apartment block, panting and red-faced both from the exertion and from biting down on the spasms of pleasure as she gripped her twin cocks close to her body.

Rich was down there, picking up his mail. Their next-door neighbour, Rich was a pleasant, attractive man in his early twenties with short blond hair and a slim build. Before her accident, Olivia had rather fancied him. Now, even just being around him embarrassed her.

"Olivia! How are you?" She mumbled something in return, trying to hide her pointed teeth. He pointed back toward the end of the foyer.

"The elevators broke down while you were out. Don't worry, though, I'll give you a hand back upstairs."

Grateful for the assistance, even with her body screaming to fuck him, she gave him a small smile. The trip up the stairs was tedious and uneventful until the final stair, when the last bump jolted something that fell to the ground with a clatter.

"Whoops! Don't worry, Olivia, I'll grab it."

"Grab what?" She tried to turn around in the chair, her eyes going wide. "Wait, Rich, DON-"

The rest of her sentence was cut off by a blue flash, and Rich falling to the ground. Checking they were alone, she slithered out of her wheelchair and dragged him back into her apartment.

Rich slowly awoke on an unfamiliar couch, blinking sleep out of his eyes. He felt...  Odd. Heavy, sore, along with another sensation he didn't recognise that crept at the edge of his consciousness. He shifted his thighs and shuddered as it flared up in his groin. With that it was as if his body woke up, twinges of sensation firing from unfamiliar areas.

"Olifia? What ha-" He stopped, both at the feeling of his lips and strange pitch of his voice. Reaching up he realised his lips were swollen up, thick and slimy like he was wearing lip gloss. He then caught sight of his hand, slender and soft with long delicate nails, like a woman's.

Panicking, he went to sit up, and became aware of the heavy weight on his chest. A questing hand slammed into the underside of a soft, fleshy mound, setting jerking motion all throughout his chest. Bolting upright, he looked down and watched a massive wave of breast flesh rise up and come down against his chest and stomach with a resounding slap, sending tremors through his body and forcing a moan from his lips.

He hefted them; biting down a rush of pleasure as his slim hands sank into the pillowy flesh. Larger than he'd ever seen in his life, they had his incredibly pale skin and freckles, and also bore a tracing of blue veins. His nipples had expanded immensely, as wide as bottle caps, an inch long and bright pink.

Wiggling, he pulled them apart to stare down between them and almost choked. His waist cinched down impossibly, and at its narrowest had to scarcely be wider than his neck had been before he transformed. It flared out into gigantic curved hips with thick thighs that tapered down into slim legs that seemed almost too small to carry such curves.

Most shocking was his penis, now a distant memory. Spreading his pale thighs apart, he saw it had been replaced with a clitoris that bulged out of its hood obscenely, easily the size of a golf ball, his new pussy drooling underneath into a damp puddle on the couch, the bloated lips glistening. He pushed his thighs together again and nearly squealed as the sensitive folds grated against each other, lubricated by the slick juices that coated them. Hanging off the couch and collecting in a pile was a thick curtain of curly, bright red hair.

He was impossible, some sort of adolescent fuck-fantasy of what a woman looked like and, he realised laying there in a slowly spreading puddle of his own arousal, what a woman acted like. He was so impossibly horny it almost outweighed the terror.

Gathering up his tits in his arms he tried to get up, and found it more difficult than he'd first thought. His massive chest and tiny waist gave him a tenuous centre of balance counterbalanced only by the huge globes of his ass cheeks that jiggled out in a shelf behind him. Even worse was his first step forward, with his weighty legs pressing his pussy together and dragging the lips together, almost sending him tumbling to the ground as he jumped in shock and set his swollen body jiggling and bouncing.

"O-Olifia? Are you there?!" Bubbly and perky. The voice of a bimbo to go with the body of a bimbo, it combined with his barely-contained panting and the impediment of his giant lips to announce to the world how much he needed cock.

Olivia took a deep breath, and slithered out into the front room. Rich's new body came as no great shock; she'd watched with baited breath as he transformed in his sleep. He, on the other hand, nearly choked at the site of her reptilian body.

"Olifia! Wha' happened?"

She began to explain about the lab explosion, about how she and the others had changed, and about her visit to Tammy earlier in the day, while Rich carefully made his way into the bathroom.

"And she must have, I don't know, slipped one of the remotes into my bag, Rich, I'm really sorry, I didn't mean this to happen..."

He was inspecting his eyes in the mirror; his skin pigmentation had apparently changed to give him natural deep eyeliner and shadowed sockets, rouged cheeks and deep red stick on his cocksucking lips just as a final kick in the teeth from the cartoon slut's body he was trapped in now. He hadn't stopped dripping either, a new puddle forming on the tiles between his feet, and his mouth had decided to join the party as well, his lips and chin slick with drool.

"Well I' happened Olifia!" He turned on his heel, forgetting himself as his tits tried to keep going and his ass slammed into the vanity table behind him. "Wha' am I thuppothed to do now? And don' think I can' thee thothe!"

Olivia was ashamed to admit what Rich's new body was doing to her, and unfortunately with no clothing or blanket she was hard-pressed to do anything to disguise her arousal. Rich wiped his mouth, then gathered up his breasts from where they hung down to past his navel.

"Is this all I'm good fo'? You thinking of thticking them between thethe ridiculous fucking tit-th? Fucking me like a bimbo whoh'? Th-thhoving your cock inthide me... D-down my throa'..."

Olivia heard the pitter-pat as Rich started dripping even harder, flushed underneath his natural rouge, pawing at one of his breasts as his thighs rubbed together. He tried licking his lips to clear off the strings of drool but found his tongue too short and wet, only adding to the sheen of spit.

"O-Olifia... What'th wrong with me, I need it tho badly, I need to be f-fucked..."

Olivia slithered over to him, wrapping one pair of arms around his tiny waist and placing the others on his shoulders. "It's the mutation, Rich. Just be thankful it's so easy to get off for you – Theresa can't even reach one of her pussies."

"Tho it's all okay then?" He wailed. "I can' thtop thinking about your cockth, Olifia! I try to focuth," he stopped, wiping the drool from his mouth again, "but my puthy jutht keeps begging to be filled!"

His legs were shaking, and had it not been for his thick thighs his knees would be knocking together. Olivia bit her own lip with a pointed fang, her cocks straining to cum as she watched the new girl struggle with the demands of her body. Rich turned around, crushing his tits against her.

The pair collapsed out into the front room, locked in a desperate kiss, Olivia's four hands roaming all over Rich's mutated body, grasping at his wobbling ass, his impossibly thin waist, running through the curtain of hair that hung to the floor. Rich contented himself with grinding against her, then pushing her into the lounge chair and straddling her. Her first cock slid up into Rich's pussy with the barest hint of resistance, the overlubricated lips accepting it like a hand in a glove.

As soon as she was deep inside him he seemed to tighten up, clamping down on her pole and making her nearly scream. His breasts hung down around her second cock, inviting her to squeeze them together to create a cleft to fuck.

She barely had to thrust with Rich's insides writhing up and down the length of her cock, and was content to lie back, moaning, jacking her other cock off with his tits. He snapped forward with orgasm after orgasm, spit dripping from his gaping mouth under his dazed eyes. Olivia drew back and thrust once, the slickness of his vagina greasing her way, and was rewarded with Rich losing control, flailing and screaming with an even more powerful cum.

Rich came countless times before Olivia finally did, groaning as she shot hot cum up into his pussy and across his face and cleavage. He desperately scooped it up and slurped it into his mouth, falling back and screaming as a final, extra-powerful orgasm overtook him, leaving him unconscious for a few moments.

His eyelashes fluttered as he groaned back into consciousness. The worst of the need had been sated, but his pussy still dripped and his skin tingled with pleasure. He still felt empty inside. Olivia stretched, drawing him in close with her four arms.

"Olifia, I-I thtill need it... It wathn' enough. I need a bigger cock!"

Olivia knew exactly what he needed.

Theresa crouched over Elise's cock-body, pressing her hanging boobs either side of the massive shaft using her legs, rocking back and forward. Their massive breasts rubbed together, Theresa leaking milk over Elise's tiny nipples. Elise suddenly screamed, her body tightening up, her boobs wobbling as she shook, preparing to cum. She gripped her boobs tight and squeezed them as a gout of cum burst from her cock, the eye distending to pump out a gallon of spunk with just her first shot.

Tammy raised her legs, letting the flood spread under her chair, fiddling with a remote her lap that rest on the base of her flaccid cock before snapping it back together with an exultant yell.

"Fantastic! This thing should be all ready now." She looked over at Theresa's rear as it flexed, her powerful legs squeezing more cum out of Elise. "How is she?"

Theresa turned around, wiping her hair out of her eyes. "Insatiable! This is the fourth time she's cum and she's still hard!" Her breasts were tight with milk and both pussies were dripping wet.

Tammy threw on her large coat, checking that it covered her body. "Leave her be, then. Come on, I want to test out the modifications to the remote."

Theresa looked down sadly at the girl. She was practically immobile and incapable of pleasuring her mutated body – she couldn't reach her nipples, and her cock was too huge for any sort of stimulation she could do to work. Elise whimpered every time her body throbbed.

"P-please... I need to cum..."

"We can't leave her like this, Tammy. You go. I'll try and calm her down."

Tammy shrugged and headed out. She didn't have time to argue. Just in front of her house were a happy couple taking an afternoon walk, from who, Tammy gleefully hid behind the hedge, pointing her remote at them as they passed and sending a thin beam of light at each of them in turn.

The man was the first to stop, a pleasant-looking slim blonde who grabbed the fence as his legs wobbled. His girlfriend rushed to hold him but he fell forward out of her arms, bracing himself up from the sidewalk, trembling on useless legs.

She bent over to help him and gasped as her pants stretched tight over her ass. The fabric creaked, even when she bent back up, her hands flying to her swelling rump. On the ground, the man flipped over, the front of his shirt starting to bulge out with a pair of breasts, his hair growing out and flowing down his shoulders in long blond locks.

Tammy crouched down further to ensure they couldn't see her, feeling the pulse against the back of her teeth as her tongue started to grow erect watching the scene. The man's pants bulged and swelled as he grabbed his new breasts, starting to split along some of the side seams, pale flesh bulging from the tears.

He screamed as they shredded apart, his legs tumbling apart into masses of fleshy tendrils that whipped about until they settled in a heap on the ground in front of him. Each one was wrist-thick and tipped with a swollen, bulbous glans, giving him two dozen writhing cocks all dripping with precum.

His girlfriend had staggered back, still grabbing her ass. The seat of her pants had given way and now her panties were struggling to stretch over two enormous cheeks. She squealed as they suddenly surged out, two lumps growing out from the bottom of the cheeks that quickly formed into feet. They stretched down until a second pair of legs sat just behind her first ones. They stumbled back as the new torso started to lengthen until she had a humantaur body like Theresa.

Unlike Theresa her breasts stayed the same size. Instead, both of her clitorises began to grow out and thicken, changing shape before her eyes. Her rear pussy lips swelled up at the same time to become a hanging pair of testicles for the massive cock still swelling from between her rear legs. The front one just grew up above its drooling pussy.

Losing control of her rear legs she fell back onto the asphalt, huge cock bobbing up and down as it grew beyond her front waist, wider around than her thigh, with a pair of melon-sized balls lay heavily on the ground below it. Her other cock reached up to just below her breasts, and only as thick as her wrist.

The octopus creature that had been her boyfriend moaned, pulling herself along by her arms as her cock-tentacles flailed uselessly. Gradually she began to push herself using them as she gained greater control over her new limbs until she sat in front of her girlfriend, grinning and raising a few of them up to coil around the enormous trunk of the humantaur's penis.

A small crowd was gathering as the mutated couple started to fuck with abandon. Tammy grinned, and twisted a dial on the remote.

Olivia and Rich carefully made their way back to Tammy's house. Rich had draped himself in a makeshift toga made out of a bed sheet, wrapped up between his thighs to soak up his juices and hopefully take a little pressure off his pussy lips. Walking was still a struggle, and he had to frequently stop to try and recover his composure. By the time they rounded the corner to Tammy's street he was flushed and trembling, the sheet around his pussy soaked through, strings of drool dripping from his mouth and chin.

The scene before them on the sheet left them speechless. A tangle of orgiastic flesh writhed on the asphalt, easily a dozen people, all women, all in various states of mutation. A girl whose forearms had morphed into giant cocks dragged one between one of the sets of cleavage of a girl whose body was ringed with massive breasts, while the other was tugged and pleasured by the enormous tongue of a third girl.

Six of the eight arms of a woman whose body had morphed into a sort of human spider were busy rubbing the half-dozen penises sprouting from another woman's crotch, one working away at her own pussy and the other rubbing the soccer-ball sized clit spreading apart the thighs of a third woman. She groaned, tugging away at her enormous nipples, kissing the face of another girl whose mouth had been replaced by a vagina, her nose a bloated clitoris.

One girl who appeared to be about twelve feet tall lay back against the sidewalk cradling breasts too big even for her massive height, her nipples being sucked by a girl with two heads, four arms, four breasts and four legs. Another girl was locked in a threesome, apparently built for the activity as her back had become a copy of her front, giving her a second face and set of breasts on the back of her head and torso, and double-jointed arms and legs. Her partners were a dickgirl with testicles the size of a beanbag chair, and a girl whose massive breasts and udder burst with milk.

Olivia had to practically drag Rich past the scene, staring open-mouthed and rubbing himself. He whined and moaned the whole way until Olivia was able to bring him inside the house, slamming the door shut. He collapsed against the door, panting.

"P-pleathe, Olifia, I need it tho badly..."

He turned around and went slack again. Theresa was stepping off Elise's cock. Her breasts were painfully taut, bobbing against each other as they swung heavily with milk packed in so tightly it dripped from her nipples. Elise was still writhing, red in the face and looking up pleadingly at Theresa to cum, but the humantaur was too gripped by her own needs to continue.

A moan escaped Rich's mouth as his hands started rubbing even faster. A string of drool dripped from his bloated lips as the massive shaft throbbed, sending Elise's upper body bouncing, her boobs jiggling atop the base of the trunk coming down on the rigid meat with a fleshy slap.

Rich didn't even realise he was stripping off the toga, revealing his bimbo body in all its hourglass glory. Small phut sounds rose from the floorboards as the steady stream of juice from his pussy started hitting the ground, dripping even harder as he watched the massive, pulsing cock on the floor.

Olivia watched as Rich planted his plush ass right at the tip, already belching precum as Elise watched Rich's rack wobble back and forth. She considered pulling Rich back for a moment, too far gone to realise there was no way he could fit the huge cock inside himself, but the sight of what happened next left her stunned.

Rich rammed his pussy at the tip, and howled as rather than simply hit the tip, his pussy opened up as soon as they touched together. It started to expand as Rich wiggled his way down the head, his pussy actually swelling to cope with the meat he was stuffing inside it.

His hips widened as his legs spread apart to accept the monster. It wasn't long of course before the tip reached beyond his hips, but his body seemed to be prepared for that, too. It travelled through his tiny waist with just the barest hint of swelling, like his entire torso was nothing but a fuck-hole.

No longer wiggling, Rich practically foamed at the mouth with pleasure. Olivia noticed that he was still somehow working his way further down Elise's cock without actually moving, quickly realising that his torso was actually stretching, growing down the length of the cock until his waist formed a three-foot long cock sheath.

Olivia was broken out of staring at the absurd sight by Theresa staggering over to her, whining, desperately babbling to be milked. She took her spot underneath the girl and started working at her four lower tits while Theresa handled her top two, and the other mutant women fucked like they were made for one another. Milk splashed out onto the floorboards as Theresa groaned in ecstasy, massaging her aching breasts and shuddering, nearly losing footing.

"Where did Tammy go?"

"Ooh... I don't know... She saaaah-said she'd fixed up the remote to give it more range..."

The two stopped dead as they both turned their heads, watching the blue flash outside that engulfed the city.

(continued)

Brooke stepped off the bus at Houghton station, still wrapped in the blanket. Her erection had finally gone down, but that just meant her balls had grown even faster.

She spied a figure standing at the corner of the station, outside the lights, wearing a large trenchcoat. It turned to the side, revealing a second head that made Brooke gasp.

"Katrina?"

The girl turned both heads towards her, breaking into double smiles. "Brooke! You-"
"-finally came! It's-"
"-so great to meet you!"

She ran forward, pulling Brooke into a deep hug. Brooke leaned in for a kiss on the cheek to the blond head. Katrina poked the cheek of her brunette head.

"And now-"
"-this one."

Instead of a peck on the cheek, though, Katrina moved her mouth to catch Brooke in a deep tongue kiss. Brooke shuddered, feeling her cock pulse almost instantly and start to throb before she pulled away.

"What are you doing?!"

Katrina's brunette head grinned. "Saying hello, cutie. It's how we-"
"-muties do it. Come on, we're only a block-"
"-from here. You can meet-"
"the others."

The final line was spoken in unison. Katrina seemed to not have great control of which head was speaking, with sentences jumping back and forth between the two or coming from both.

It was only as she began to walk away that Brooke noticed her three-legged gait. Her legs moved forward in a back-and-forth order, middle, left, middle, right, middle. Brooke had to practically jog to keep up with her, holding her boobs tightly under the blanket. "Did that take much getting used to?"

"Yeah, it took-"
"-me a while. For the first-"
"-couple of weeks I kept tripping over."

She giggled a stereo giggle. "I got used to two cunts right away, though!"

Brooke was uncomfortably aware of her reaction to Katrina talking like that, feeling the lurch in her groin muscles. "How do you deal with... you know, the urges? How do you stop yourself from just touching yourself all the time?"

Katrina's brows wrinkled. "I don't understand? Why-"
"-would you stop touching yourself?"

Brooke huffed, her balls bouncing off her legs as she tried to keep pace. "I mean, can't it- doesn't it go away? If you stop?"

The doublegirl laughed, a crystal-clear stereo mirth. "Oh, baby, no. It never-"
"-goes away. There's no "cure." We're-"
"-stuck like this."

She winked with her blond head. "Not that I mind."

That stopped Brooke dead, her nuts swinging forward with her momentum and her boobs bouncing. "You- you LIKE this?"

"Honey, you never realised?"
"I mean it was a shock, yeah, but-"
"-after I got used to it, I started-"
"-loving it."

The idea that her friend enjoyed her condition had never occurred to Brooke. She knew Katrina had come to terms with it, and certainly enjoyed the sex, but just enjoying what she was? That was possible?

"How could you enjoy this? What's happened to us?"

"How could I not? I'm-"
"-hot, my body feels great. All the, like-"
"-questions you normally have about what you-"
"-should be doing and why just disappear."

She sighed, almost happily, speaking in unison. "I feel... free."

"Don't you miss your family? Your friends? Your life?!"

She shrugged. "This life is better. I'm-"
"-interesting. I'm a freak. I'm-"
"-sexy."

Brooke couldn't deny that. She was still nursing a semi-hardon from Katrina's kiss earlier. Katrina pointed over toward a run-down building.

"Over there. We're squatting."
"There's power, and we get municipal wi-fi."
"Come on, I want you to meet the others."

Brooke climbed a few stairs and ladders behind Katrina, trying and failing not to look at the girl's triple-cheeked ass. She was fully hard by the time they got to the right room.

As abandoned as the rest of the building, it had been made cozy with blankets, pillows and light, carving out a large comfortable corner. Several laptops and a smartphone were plugged into a power strip that led out the door.

Two girls were on the cushion pile, one of them waving to Katrina as she walked back in. The other pouted sullenly.

The pouting one sat with her arms folded underneath her immense bust. It was even bigger than Brooke's, but appeared to be somehow  perkier, standing out in almost perfect teardrops. They were so perky that they somehow only curved down to just the top of her stomach, where Brooke's enormous, more natural-looking mounds hung to her navel.

She was nude, but wreathed in a waterfall of wavy hair so blond it was nearly yellow, that cascaded on the cushions around her and would have hung nearly to the floor when she stood up, extending a foot out either side of her body.

Her face was perfectly, if thickly, made up, with dark eyeliner that made her eyes look huge and vapid and bright pink lipstick on her thick, plush lips. Brooke could just see behind the mass of her boobs that she had a tiny, pinched-in wasp waist.

The other girl was actually clothed, though her top appeared overstuffed and her skirt revealed a large tent and attempted to wrap around wide, curvaceous hips. Brooke realised her shirt was overstuffed because of the third breast nestled in it, and though her breasts weren't close to Brooke's own, let alone the other girl, they would have been called large on any conventional woman.

"Brooke, this is Soleil-" Katrina waved a hand at the clothed mutant, "-and this is Alex."

Soleil wandered into the bathroom, sweating. She'd been all ready that morning to head into the office and put the finishing touches on the Pandesky case, but she'd suddenly come down with a case of nausea.

By the time she'd reached the bathroom, though, the sickness had faded, but had been replaced with a burning heat all through her chest, focused on her (rather large, she was proud to say) breasts, as well as a similar heat in her groin.

She stripped off her suit jacket and her button-down shirt, revealing a utilitarian white bra. She could feel a strange tingling on her ribcage, right between her breasts. She poked there and gasped as her finger sank right down to the first knuckle in what should have been bone.

When she withdrew her finger, a small bump popped up along with it. As she looked on in shock, it swelled further, changing shape and spreading out until she could only describe it as an erect nipple.

She groaned as pressure built up in her breasts and behind her new nipple, along with a similar pressure through her hips and her pubic mound. She felt the pressure flare, and her boobs surged against the cups of her bra, the fabric of the straps creeping as titflesh swelled against the cups. At the same time, her tight pencil skirt tore down the sides as her hips suddenly widened several inches.

The pressure was especially bad in the centre of her chest, and even as her boobs expanded she could see the bump between them playing rapid catch-up until it wobbled and jostled for space in her already overstuffed bra. She reached back and unhooked it, letting out an involuntary moan as her heavy breasts fell free and slapped against her chest, including what could now only be described as her third tit. She touched its nipple and pitched forward, knees shaking as pleasure rocketed through her body. Her clit lurched hard, the pressure in her groin doubling behind it as she cupped and palmed her swelling, hypersensitive breasts.

Her clit suddenly tightened even more, her muscles straining hard. There was a slash of blinding pain through it and a sickening organic noise, and a large, misshapen bump began to rise up in the front of her skirt. Trembling, she reached a hand down and touched it, gasping as it throbbed.

It swelled further, straining at the already-ruined shreds of her skirt until they tore completely, allowing two thick thirteen-inch cocks to fall down and throb to full erection, holding up the remaining flap of her skirt.

Transfixed, she pushed the flap of fabric aside, peering over her expanded triple-bust to watch them throb. Still cupping one of her breasts with her left hand, she reached down and wrapped her right hand around the top shaft, taking in a sharp intake of breath as the pleasure flooded into her body.

She began to rub her hand around it, teasing into the ridge under the head with her fingers and stroking her nails lightly down the underside, making her shiver and gasp. Within minutes she was slowly stroking it, exulting in the sensation all the way up the lengthy shaft. It was the biggest cock she'd ever seen and she had two of them. She knew she should have been upset, even freaked out, but the sensations were too good.

She looked around, realising someone could walk into the bathroom at any moment, and ducked into a stall, her cocks bouncing as she moved. She felt underneath them, finding a swelling bump at the top of her pussy, just below her lower shaft. Her pussy suddenly felt full, like there was something inside her. Her muscles spasmed and, with her brow crinkling in confusion, she pushed.

An egg-sized mass popped out from under the lump, filling and stretching the skin around it and drawing a yelp from her  The sensation grew again, and within minutes she'd pushed a second fleshy egg into the rapidly-swelling sac.

She went back to stroking herself, periodically groaning and pushing another mass out. After the first one, her cocks had begun leaking, pearly precum beading at the tips and dripping down the length of her shafts. She'd gripped and tugged her hand from the base to the top of her upper dick and been rewarded with a weighty glob of the stuff that dripped down over her hand, lubing the passage of her fingers.

She was a throbbing, hot, sloppy mess. The flow of precum didn't stop, and if anything only increased as she jerked her dick, ignoring the protesting throbs and the petulant dripping of her other shaft. I'll deal with you later!

Later, however, didn't seem forthcoming. She sat and tugged for what felt like ages, and though several times she felt it get tantalisingly close, each time the feelings receded, leaving only a belch of precum in its wake. She stopped, panting, realising that whatever she was doing wasn't working. In the interim, she grunted and squeezed out another testicle into her overstuffed scrotum, both shafts heralding the event by dripping more goo.

This isn't working. Maybe if I... She pulled her left hand from her tender breast and reached down to her lower dick, starting to pump it amateurishly as her right hand went back to work. The sensation from double-masturbation was nearly too much to bear, her hips bucking as moist gasps died in her throat.

Keeping up a rhythm on even a single cock with her dominant hand was hard enough under the onslaught, let alone jerking off two at once. She did her best but her efforts were fruitless, both cocks stuck in a cycle of coming close to orgasm and then fading, leaving nothing but a horrifying tease and another voluminous string of precum in its wake. It seemed that unless she got both cocks on the edge at the same time, she couldn't cum. She started to sob, her hands soaked in her pre, gliding up and down the slick shafts of her dicks in trembling staccato motions as she tried her hardest to finally bring herself off...

Katrina sprawled out on a pile of cushions, kicking off her shoes and stretching back, curling her toes. She motioned to Brooke.

"Sit down, make yourself at home, babe. We're here for one more night. I organised a Rebirth Bus to pick us up."

Brooke took a seat near Soleil, spreading her legs apart to allow her sack space between them. The action caught the girl's eye, and she winked. "Space issues, hey?"

Brooke flushed. "Uh, yeah."

Soleil gave her a friendly punch to the shoulder. "Don't be embarrassed. We're all freaks here. How many do you have to fit down there?"

Brooke's brow crinkled. "Uh, two?"

Soleil sighed. "Lucky." She lifted up her skirt, spreading her legs a little further. Brooke gasped at the sight of her twin cocks and bulbous, misshapen scrotum. She girl reached down, palming her sack, and it was plainly obvious that the shape was because it contained a multitude of egg-sized testicles. Her cocks throbbed, and a fat wad of precum belched from each of the tips, rolling down the shafts.

"I've got twelve of them, I think. I don't know for certain. They're, like, always working overtime as well, so I pretty much constantly leak."

She sighed again. "The worst part? I'm leaking and horny all the time but unless both my dicks get off at once, I can never cum. That makes it really hard to masturbate."

Brooke flushed hard, turning her head away. She'd found herself becoming transfixed by the sight of Soleil's mutant genitalia, feeling the stirrings in her own cock. She heard the girl giggle. "Oh, it's nothing you haven't seen befo- uh, okay, maybe it is, but don't worry. We're all friends here."

Katrina chimed in. "In Rebirth, people walk around naked all the time. They-"
"-say hello with kissing and sex is, like, just something you do as friends."

"Gross." That was Alex. "There are probably penises everywhere."

"I hope so!" Both of Katrina's heads smiled. "I like dicks."

The bimbo girl sneered, or at least tried; her vapid expression made it look more like she'd accidentally stepped in a puddle. "Weren't you a fuckin' guy before?"

"So? Doesn't really matter after-"
"-you mutate. It fucks with everything, your-"
"-sexual preferences included. It was weird-"
"-at first but at some point you just have to-"
"-accept that you're into penis."

Alex sniffed. "Fuck that. Nope. The mutation hasn't changed my head, no matter what else it's done to me."

Soleil looked thoughtful, laid back with her skirt still hiked up and her cocks periodically disgorging a glob of precum into a puddle under her ass. "Do guy and girl even mean anything any more to us? I've got two cocks and a vagina. Katrina's got two pussies. Brooke's got-"

She looked over meaningfully, and Brooke flushed even harder. Katrina chimed in. "Just the cock."

"Okay. And she started out a girl, even. So, what does it all mean? Is she a guy now? What if she had a pussy? Does that change it? Aren't we all just basically mutants now?"

"I'm a woman, and I like other women. Simple as that. I'm not weak enough to have that dictated to me by some disease."

Katrina laughed. "Except for the part where you're a walking bimbo fuckhole gagging for dick twenty-four-seven."

Alex growled, rolling forward on her enormous shelf of an ass. Brooke could see thick strands of pussy lube following her. She'd been stewing in her own juices. "You fucking cunt! How dare yo-"

She stopped, wide-eyed. Katrina, grinning evilly, had turned her heads inwards and locked lips, drawing herself into a deep, passionate kiss. Her hands crossed her body, her lower-left hand dropping to her right pussy and her upper-left cupping her lower-right breast. Her right hands both moved to a breast.

The three remaining girls sat in stunned silence as Katrina engaged in a one-woman lesbian makeout session. Her hand rubbed in rapid circles around her pussy, Brooke realising that each of her mounds came equipped with two clitorises side-by-side. She moaned, one of her faces breaking off the kiss to start panting as the other side of her body went on the offensive, rubbing its pussy hard and practically mauling its bountiful breasts. Brooke wasn't sure if Katrina even realised what was happening, but she seemed to be falling into a dom-sub relationship with her own body, the blond head taking the initiative as the dark-haired head whined in pleasure.

Brooke heard a choking noise and looked to the side as Alex pitched forward onto her hands and knees, her hips gyrating. Alex looked at her with teary eyes, making another choking noise. Her mouth opened and Brooke gasped as a large penis slowly pushed out from behind her plump, pink lips, and then pulled back in. She let out a deep, muffled moan and there was a slick noise, her legs spreading apart. She heard it again and again, each one accompanied by a thrust of the pneumatic mutant's hips, and Brooke realised she was being fucked from the inside out.

Soleil stepped forward, slowly tugging on both of her cocks, spraying a small spurt of precum in front of her. "That's the other part of her mutation. She waits too long or gets too horny without sticking something inside her? Her body basically rapes itself. Her mouth and both of her pussies."

Brooke's quizzical look made her go on. "She's got a second pussy between her ass cheeks. Surprised she got away without one instead of her mouth, as well."

The cocks had picked up speed, leaving the writhing girl being savagely, mercilessly fucked by rapid, pounding thrusts. Brooke knew she was in distress, but on the other hand watching Alex's massive tits swing back and forth, watching her round ass gyrate as each pair of thrusts ravaged her pussies, had Brooke at full mast.

Soleil knelt down behind Alex, biting her lip, positioning the tips of her cocks at both of Alex's holes. She thrust forward, groaning deeply.

"You- uhhh- see, if someone's-ugh- filling a hole, she doesn't fuck it herself."

She began to thrust slowly, her hands running across the the curve of the girl's ass, her three tits heaving with each roll of her hips. Alex squealed around the dick in her mouth, her eyes rolling as a massive orgasm wracked her body. Brooke's cock lurched hard, making her gasp in pleasure. Her balls were tight and aching, and she could tell she was going to have to drain soon. Despite the fact that two of the mutants were fucking in front of her, though, she still didn't want to reveal herself, blushing furiously and trying to push down her erection.

Transfixed by the sight of copulation in front of her, she didn't notice Katrina walking over to her until she felt her skirt sliding up her legs. She squealed, kicking her legs lightly, but Katrina grabbed her ankles with her lower arms, still lifting the skirt up.

"Oh come on, Brooke, you don't meet three new mutants-"
"-and slink off to masturbate. Besides, what am I supposed to do?"

She flipped the skirt over, unveiling the fat, pulsing shaft. She licked both sets of lips, moving her hands to the bottom of the shaft and starting to tug.

"You've such a big, sexy fucking cock."
"It's not the biggest I've ever seen but-"
"-it's just right. I don't need you to have-"
"-a dick bigger than your body. This is perfect."

She shifted forward, letting go of Brooke's legs as she stopped struggling. Katrina pushed her upper boobs together, wrapping them around the upper half of Brooke's dick, her lower arms still slowly pumping the shaft. She licked her lips and leaned forward, her boobs sliding down Brooke's cock to allow the rest of it to project up between her heads.

They turned inwards again, showing off her amazing flexibility, and started to lick and plant sucking kisses up either side of Brooke's cock. Her right head, the blonde, stretched her mouth wide to fit the tip in, staring straight into Brooke's eyes as she sucked, while the brunette kept licking up the underside and mewling in pleasure.

Brooke nearly blacked out. The sensations shuddering from every inch of her oversized dick were like nothing she'd ever felt before. Katrina's mutant body and her own immense size created the possibility of a full-body experience unimaginable by regular people. The heads began switching off, the blonde moving off to start licking the underside while the brunette teased the tip with her tongue. One of Katrina's lower hands slid down and began to gently cup and caress Brooke's balls.

"These must be so full. How long has it been for you?"

Stuffed full of cock, the other head stopped trading off speaking. Katrina grinned at the writhing dickgirl, still gently fondling her nuts while one hand rubbed up and down the bottom of her cock and the top hands kept pressing her upper set of breasts against the shaft.

Brooke moaned, and Katrina took the opportunity to pop her mouth off the end and push forward, levering Brooke's cock into her own mouth. Brooke's eyes went wide in sudden surprise, and Katrina lifted her arms up to press all four breasts around the shaft and slide them down so her heads were level with Brooke's breasts, taking a nipple into each mouth.

The combined sensation of a triple titfuck, sucking herself off and having both her nipples sucked on at once was too much, and within a couple of minutes she moaned into her cockhead, her abdominals tensing, and then her eyes going wide as a load of cum forced its way up the length of her shaft and exploded into her mouth.

She choked on the first and second loads, her cock finally leaving her mouth at the third shot taking an overstuffed mouthful of jizz with it. Katrina laughed, milking more hard shots out of Brooke's cock with her breasts, until she sat back and just slowly pumped with each crippling spasm through Brooke's body.

While Brooke was cumming, Soleil finally grunted, grabbing hard onto Alex's ass cheeks and bucking as she deposited a hard double load into the girl's twin pussies, falling back and sighing with strings of cum trailing to her dicks. Alex slumped forward, dazed in the afterglow of dozens of rapid-fire orgasms.

Soleil looked over at Brooke, writhing on the bed of cushions as she shot off again and again, and purred, watching the sight with interest.

"Wow. When does she stop?"

Katrina smiled, giving Brooke's cock a hard pump with her next shot, making the girl shriek and cum extra-hard. "Like ten or fifteen minutes. She-"
"-doesn't stop until her balls are drained."

"Wow." Soleil grimaced, her cocks lurching back to erection, two more huge globs of precum oozing from them to slide down the shafts. "I wish I could drain all my balls at once."

"Even if it-"
"-took you hours?"

The pair watched Brooke scream and sob for a moment, clutching the cushions and humping her hips into the air, the lengthy pole of her dick shaking strands of cum across the room.

"Uh, yeah? I'd trade with any of you in a heartbeat." She looked over at Alex, slumped forward on the pillowy mass of her tits, still shivering with residual orgasms. "Well, uh, maybe not her. At least she can still satisfy herself, though."

Katrina smirked, gently rubbing a few of her nipples. "Yeah I think I got the best deal-"
"-out of this. I don't know if you're better off-"
"-than Brooke, though." The girl was crying now, wracking sobs that coincided with each burst of spunk from the end of her gigantic dick. "How would you ever-"
"-get used to that?"

Soleil shrugged, running her hand up one of her cocks to clean off a layer of pre, flicking it off onto the floor with a wet slap and shuddering with the sensation as both her cocks lurched. "Am I ever going to get used to this?"

"Heh, probably not. We're-"
"all fucked, aren't we?"

"Amen, sister." Soleil looked across Katrina's body, her four erect nipples and the flush of her cheeks, and particularly the moisture across her twin pussies. "Speaking of fucked, uh, are you up for it?"

"Thought you were never-"
"-going to ask."

She crawled over, swinging one set of legs over Soleil and sinking down onto a cock with a groan of relief. Soleil gasped, shaking her head.

"No, no, not just one-"

Katrina placed a finger on the girl's lips. "Shh. Let me-ugh-"
"-sort it out."

She wrapped one hand around Soleil's upper cock. Another snaked behind her, under her wide ass, to lift up Soleil's overstuffed scrotum and sink a finger or two into her pussy. She bit her lip in concentration, moving another hand up to Soleil's triple bust, and finally positioned the last one down at her empty pussy. She began a complicated dance of stimulation, lifting and grinding her hips, jerking, fingering and rubbing, while her lover writhed underneath her.

Alex stirred as her stomach churned in pain, blinking the sleep out of her eyes, smacking her lips at the taste of stale booze and cigarettes. The lithe little blonde with the undershave in the bed next to her turned over, but didn't wake up.

What a night. It was always fun breaking in a new dyke. She'd been beginning to despair of finding anyone, especially after the first person she'd sidled up to at the bar had turned out to be a fucking tranny.

She pulled on an old, loose tank top and a pair of jeans, and stepped over a pile of newsletters, emblazoned with a large fist atop a circle and cross. She had to remember to bring the rest to the meeting tonight so they could go postering around the campus. It was hard, getting a radfem group started up a small-town college, but somehow the difficulty improved the fun.

She stared at herself in the bathroom mirror. Her buzz cut was beginning to grow out a little. She might get it coloured this time. As she got a glass of water from the sink, her stomach churned with another sudden bout of nausea. Jesus, what a fucker of a hangover. I didn't drink THAT much, did I?

She flopped down on the sharehouse couch, fighting down the urge to throw up. She felt clammy and shivery, but with a strange heat flooding through her core and out to her chest and hips, and also through her face. She wiped cold sweat off her forehead and ran her fingers down her face, and stopped as she felt a burst of sensitivity from her lips.

Are they... She touched her upper lip gently. Are they swollen? Am I having an allergic reaction or something?

She ran her tongue across them and shivered lightly. She soon realised that her nipples were erect, the tips of her tiny tits showing up through her tank top. As she lifted an arm to brush over one, she felt a prickle all throughout her armpit, soon realising a bunch of her flourishing armpit hair had fallen out. She also felt a twinge in her clit, and a hot, sticky sensation of arousal.

What the fuck is going on? There was a flood of pressure behind her breasts, and she could swear she saw them swell behind her top, the nipples pressing even more heavily into her shirt. She stepped back and groaned at the tightness of her jeans around her ass.

She stumbled back in to the bedroom, gritting her teeth at the pull of the fabric across her skinny butt. Her playmate from last night was awake by now. "Hey, uhh-"

She looked at Alex levelly for a moment. "Cody."

"Right, Cody. Uh, do I look different to you this morning?"

She shrugged. "I dunno, I was fucking wasted. Uh... Are you wearing makeup?"

"What?!" She sprinted back in to the mirror, uncomfortably aware of her chest bouncing. Her eyes had formed a dark outline, her skin clearing of its pockmarks. Her lips were truly pouty now, and seemed to be slowly turning a brighter shade of pink.

"What the FUCK?!" Her hair had joined in, easily an inch long now. Where before it was a mousy auburn, the new growth was a spun-gold blond. Her new tits surged forward with a swell of pressure, soon joined by her ass, straining so hard against her jeans that they creaked when she moved. They also sported a tremendous wet patch at the front.

Back in the bedroom, Cody was browsing her phone, and looked up when Alex stumbled back in. "Are you trying a new look? It's really femme, but, uh, I'm not sure how into it I am? Honestly I kind of only got into it last night because of how much you looked like a guy..."

"No, uh, Cody! Something's happening to me! Look at these!" She thrust out her chest, uncomfortably aware of them actively swaying and jiggling to a stop. "I'm growing fucking tits! This isn't just a new look!"

Cody's brow wrinkled as her thumb swiped down her phone. "What? That's ridiculous. You're probably bloated or something from last night. Maybe you should go to the doct- haha, a friend of mine on Facebook is saying he's turning into a girl. And, um, there's a related news article..."

Alex snatched the phone from Cody, tapping it to open the news article. She realised her normally short, chewed-down fingernails were half an inch long now as one of them tapped the screen before her fingertip. She fanned out her fingers, open-mouthed, before looking back at the article.

"Unbelievable stories of bizarre transformations are flooding international news networks... No scientific explanation... Disturbing and sexual..."

She subconsciously pushed a lock of sweat-streaked golden hair from her face, then stopped, realising her hair was already long enough to reach her eyes. The pressure had redoubled in her tits and ass. Itching need was building rapidly in her pussy.

"Fuck! Look at my tits, they're, like, C-cups!" She dropped the phone to the bed, hefting her new mounds, easily filling her hands.

"C-cups? Have you ever bought a bra that wasn't a training bra? They're at least double-Ds, maybe even Es."

"Fuck!" Her loose tank top was no longer even coming close to hiding the bulk of her new tits, and when she turned around to head back into the bathroom she squealed as her jeans, now impossibly tight, shredded down the sides to make room for her globular rump. Worse still was the feeling of the fabric tight along her pussy, like that had swollen as well.

"Cody! Call a fucking doctor or something! Jesus!" She could feel her lips smack together, each contact sending a bolt of pleasure to her overworked snatch, along with every motion of her bloated boobs.

"What's a doctor going to do?" Cody was browsing her phone again, looking up what she could about the condition. "It says they can't do anything about it, so just make yourself comfortable and wait it out?"

Alex groaned, falling back on the bed and lifting her ass so she could try and struggle out of what was left of her jeans. Her boobs slid down her chest with a hefty weight, and, after she managed to pull the sides of her jeans together long enough to unhook the fly, she managed to slide them down across her hips and kick them off onto the floor, revealing the vast expanse of her new hips and thighs.

Her pussy was soaked through, juices leaking out onto the sheets, and was completely bald as well. Most horribly, her clitoris seemed to have disappeared, leaving nothing but smooth lips. It still practically ached to be played with, and before long Alex had a hand working away inside her pussy, the other reaching up to cup and pinch the enormous nipple tipping one of her still-growing breasts.

"Yeah. uh, it also says that an overcharged libido is a common side effect."

Alex drew in a rattling gasp as her body continued to swell out of control. Her hair was past her shoulders by now, her lips felt slick and glossy. She felt a bizarre writing sensation from between her ass cheeks, and when she clenched her muscles felt another sudden burst of pleasure. The rubbing felt good, but at the same time, she couldn't feel herself really getting any closer to climax.

"You look completely different. It's really freaky."

Alex moaned in response. She spread her legs, feeling sticky strands of juice separating both her thighs... and her ass cheeks? The confusion overpowered her lust for a moment, letting her dip her hand down from her pussy. It felt warm and wet, full of fleshy folds. It almost felt like another vagina had replaced her asshole.

She sobbed. Her boobs were truly massive now, but somehow still perfectly perky, with huge throbbing nipples that begged to be sucked. Her waist had pulled in, thinner than her already-skinny midriff had been before. Each of her hips and ass cheeks were practically the size of a basketball, wide and round. Her hair had fanned out as it grew, now reaching past the small of her back.

She looked over at Cody with thick, dark eyelashes, tears rolling down perfectly-rouged cheeks. "I can't even cum! How could this get any fucking wor-guk?!"

She choked. She tried to swallow, but she seemed to involuntarily choke again. She shifted her thighs, feeling something writhing inside her body. Her eyes unfocused for a moment, and Cody gasped as she saw Alex's throat ripple. Another brief moment of discomfort, another choking noise, and Alex's mouth flew open. Cody screamed as she realised the fat tip of a thick dick had pushed its way out, Alex's lips sealing around it subconsciously before it pulled itself back in.

Alex spread her legs, her screams muffled by the cock in her mouth as two more pushed their way out from the inside of her pussies, extending out about an inch past her lips and then sliding back in. They started out slowly at first, but within less than a minute were pistoning in and out of her body with savage force, her hips actually shaking back and forth with the motion, while the one in her mouth mercilessly throatfucked her.

She flailed over on the bed, looking Cody in the eyes with cold fear. Her tits sloshed back and forth gelatinously as her body writhed, reaching out for the girl who pulled herself back up against the wall, quivering.

"I can't deal with this, Alex. I signed up for a one-night stand, not this shit."

Alex sobbed, too wracked by the cocks reaming her to even soundlessly beg, just collapsing onto the bed until the penises finally gave up, countless unwanted orgasms later. Her hair fanned out across the bed in golden waves. Her boobs quivered with the slightest motion, twinging her pussy. She didn't even need to look in the mirror to know her face had completed its transition to a pouty, overstuffed parody of femininity with thick cocksucking lips and whorish makeup. She could already feel the heat building in her pussies again...

Sunlight filtered through the dirty windows of the building. The four mutants were sprawled out in varying states of dishevelment. Soleil snored, spooning with Alex, their juices pooling between them as Soleil's erect cocks disgorged their load and Alex leaked from both of her vaginas. Brooke lay where she had passed out at the end of her orgasm. Katrina slept fitfully, occasionally wrapping her arms around herself and subconsciously playing with the opposite side of her body.

Brooke was the first to wake up, groaning at the ache in her balls and the pulse of her steel-hard erection under a soft blanket. Her morning wood was the worst, carrying the entirety of her pent-up bounty from the night. She was unusually sore today, and realised that she must have slept for far longer than usual.

She shifted forward, realising how far she'd spread her legs, feeling her balls jostle and bump against each other and her thighs. She didn't want to drain; after passing out in the middle of an orgasm, she felt like she'd only just finished the torturous process of cumming, but she knew it was only going to get worse if she left it alone.

Her mind immediately went to planning; to listening out for sounds and evaluating when she could find uninterrupted time in the bathroom. She had a brief moment of panic over the fact that she overslept and wouldn't be able to find private time until far later that night, swelling the whole time, until she remembered that she wasn't at home any more. None of her current roommates were going to scream at her or call her a devil whore for doing what she needed to do to stay sane and healthy.

It was very liberating. All she needed to do was convince herself it was liberating. The hairs on the back of her neck prickled and her face flushed with shame, and all she wanted to do was roll over and hide it until she could find somewhere private. Under the blanket, she pulled her dick down against her body, stifling a moan as it bucked against her grip. Of course, that just brought it down level with her mouth, the thick head bumping against her chin, her mouth involuntarily watering.

She pulled deeper under the blanket, closing her eyes and stretching her mouth out around the head, suckling lightly as one of her hands left the shaft to sink down, cupping and caressing her swollen testicles. She moaned into it, swirling her tongue around the head, her remaining hand on the shaft pumping as well as it was able. The apprehension was always the worst, and distracted her from bringing herself off as effectively; intellectually she knew she had to cum, but the thought of another of her torturous cumshots made her trigger-shy as she felt herself begin to approach it.

Her private struggle was suddenly interrupted when the blanket was thrown off her, Katrina's grinning faces filling her vision. "Hey! I told you, no playing with yourself! Get that out of your mouth, I've got somewhere you need to put it."

She looked over, and realised Soleil was fucking Alex again. Katrina pulled her up, her cock falling out of her mouth with a pop, and shepherded her over in front of Alex, predictably bent over on all fours so Soleil had full access to both of her holes. Katrina grabbed Brooke's dick, giving it a quick kiss on the end, and lined it up with Alex's mouth.

"Katrina, i-it won't fit!"

"Yes it will. Trust me." Alex moaned as the tip brushed her plump lips, smacking them together around the cock thrusting out from her own throat. It retreated, leaving her mouth empty and watering. Katrina giggled and pulled Brooke forward, shoving several inches of the girl's dick into Alex's mouth.

Katrina moved around behind Brooke, wrapping a pair of her arms around to sink into Brooke's pillowy breasts, the other taking place on either hip. She walked forward, shoving Brooke slowly into Alex, inch after inch gradually disappearing down her throat. Brooke whined, her body flooding with pleasure, her cock lurching hard against its warm prison and her nipples pulsing with need as Katrina's hands mauled her soft flesh.

Before too long, though, she was thrusting without Katrina's encouragement, letting Katrina move her hands down to play with her twin pussies. Alex had cum many times over, squealing with each thrust of Brooke's gargantuan dick and Soleil's twin shafts.

Soleil was the next to cum, her hips shaking and her face falling into a slack rictus as she shoved up against Alex's ass, twitching with each load of cum she dumped into the girl. Brooke came soon after, her orgasm taking her by surprise in the middle of her single-minded focus on stretching out Alex's lips.

To her shock, Alex didn't move away, purring madly as Brooke shot load after load deep into her stomach. Eventually, though, she started to choke, and was forced to pull away, a flood of thick cum falling from her mouth as Brooke continued to shoot. Alex writhed in the hot shower, feeling it run down her face and across her outsized breasts.

Katrina moved away and let Brooke fall back on her ass, her balls bouncing painfully off the floor as she screamed with more crippling cumshots. Katrina moved over to Soleil, panting on a pile of cushions, her dicks having rallied back to full precum-belching erection. She turned sideways, planting her middle leg between the two shafts, spreading her other legs to make passage for them. With a rattling moan, she sank down onto them, grabbing her breasts and beginning to bounce.

Brooke was still shooting by the time Katrina brought herself off, humping on Soleil until she came as well. The remaining three girls began packing up around Brooke, pulling all their things together into bags and sacks as she humped and writhed. They didn't bother cleaning up any of the mess, electing to leave the tremendous piles of cooling cum and other juices for someone else to worry about.

Brooke finally came down from her orgasmic high, her dick weakly squeezing out the last few loads of cum to roll gently down the length of the shaft. Katrina leaned down to help her milk the remnants out, gleefully slurping it up as she did.

By the time they had finished, a loud horn sounded from outside. Katrina hurried Brooke along, pulling her up and smoothing her down, then getting behind her and shoving her out of the room with the rest of the mutants, down to the street below.

A small bus sat idling outside. Gleaming white, the side emblazoned with a corporate logo and the word REBIRTH. Katrina threw Brooke's bag into the luggage compartment underneath, motioning for the girl to step on. Brooke took one last look back in the direction of her hometown. Almost to remind her why she left, her cock slapped gently against her thighs. She sighed, stepping on the bus to greet her new life.

I stumbled across your Tumblr about a month ago and really enjoyed this series. I actually just completed a photomorph based on one of the characters from part 3: http://extramorphs.com/view/1866

Thanks for the great story. And welcome,  The Light Fantastic!

Thanks! I'm thinking of doing morphs of Theresa and Olivia next.

Here's Theresa: http://extramorphs.com/view/1870

You are a deadset legend.

I certainly have ideas for future Lab Accident universe stories. I don't have a particular story planned at the moment, though.

My attempt at a photomorph of Olivia: http://extramorphs.com/view/1884

Ey! Great story!! I really enjoyed it. It remembers me a lot my Peter & Sandra comic, as I also use a mutant radiation. I also create a post-apocaliptic world, as I think it give us the possibility to introduce several characters and infinite transformation stories. And I really love it. You have describe it perfectly the context, and how things are happening, this is something I have no skills. So, congratulations for that!!

Please, continue this story, as I think it could be neverending and always interesting!
