A horrific, anonymously commissioned story of mutations! Imagine how the mind would shatter if you were to wake up writhing in agony, finding yourself part hyena, part snake, part canine and part feline? Watching your body shift and morph far beyond common sense, rewarding you with bliss for suffering through the pain?

It's a rather terrifying tale! Perhaps somewhat hot too. You be the judge, but heed the tags!


Ari woke up, bleary-eyed, entirely too early. Maybe not, he realized, as he glanced at his phone; actually, it was just in time for his classes. He stumbled out of bed and into the small kitchenette in his shared dorm room. The coffee had been left standing overnight, but it'd do. He took the kettle and drank straight from it. Anything to dispel this horrid, shivering tiredness that he was struggling with more and more each morning.

He hadn't slept properly in what felt like a month. Realistically, maybe it was more like a week, but it was quickly taking its toll on the young man. Not that he couldn't handle it, he had suffered from recurring insomnia for years. It was that it made keeping up with his studies extremely hard. He was half asleep in class, dreaming more than paying attention - and while he could've normally compensated by doing homework, he was far too tired to do anything but lay on the couch when he got back home.

The coffee was going to give him ulcers too. It was only a matter of time. At least his tolerance was high enough that he wouldn't have a heart attack. Hopefully.

He ventured into the bathroom to take care of the rest of his morning routine, spraying on the closest deodorant and then rolling a hoodie over his hairy chest. He combed his hair, keeping a tired eye out for any spots of grey in his otherwise black hair. His parents had gone grey at an early age and he was determined to start dyeing his long mane if it happened to him. But for now, he looked good. He was happy with his appearance. Except for that burn on his arm, anyway - a memory of a much younger, dumber self - but it was easily covered by a long sleeve.

No. Class. Studies. Not hair, he scolded himself, splashing cold water onto his tired face. Class. Studies. Go.

He got dressed in whatever happened to be laying around and was out of the door in a few minutes, hoping that he'd be able to retain at least some knowledge from this classes.

It was on the way there that he saw a small poster, on the door to the lecture hall. A study, it seemed. Insomnia. His eyes scanned the poster out of order at first and he forced himself to focus for a moment.

A double-blind study for a sleep aid. Some kind of medicine, apparently. They were looking for volunteers, though the poster did have a disclaimer that participants would have to sign a waiver. They'd also be compensated, however. Well enough so that he could ostensibly afford to have some fun instead of spending all his money on textbooks and overpriced campus meal plans. That woke him up, if only a little - Ari pulled out his phone and snapped a quick picture of the phone numbers and addresses. On closer examination, the study was actually starting tomorrow, which meant that he'd missed this poster several times in his zombie-like state, walking into class on autopilot.

Screw pictures. He dialed the number and called before stepping inside.

"Pharmaceutical department," the voice on the other end answered.

"Uhh, yeah! I was going to ask about the volunteer thing you're doing. For the sleeping aid," he mumbled, trying his hardest to not slur his words too much.

"Right. That study is starting tomorrow. We do still need a few more volunteers. Do you want me to sign you up?"

"Yeah. Sure. The name is Ari, from..."

He went on to give them all the details, and just like that, it was done. He'd still need to show up early to sign the paperwork, though. But he was, at least, going to get in. Now, he just had to hope that it'd actually work. It probably wouldn't, he figured, but it was worth a try.

Just as expected, he zoned out in class, effectively asleep despite his eyes staying open. He didn't see what was actually being shown on the projector, his mind creatively replacing each image with odd dream-fragments, the text garbled and incomprehensible, and yet feeling perfectly normal. That's how it'd been since this last bout of insomnia started; he was already falling behind on his studies.

The class was over before he truly realized it'd started; it was only the murmur of the crowd around him, his fellow students packing their things and leaving that woke him up. He felt drool running down the sight of his mouth. This, he told himself as he blushed fiercely, could not continue. Not one more day. He was making a mockery of himself, while also somehow not learning anything new. A failure on all counts.

There was little point in staying in class. At least he wasn't required to attend - as long as he passed the exams, at least. Ari chose to return to his dorm and collapsed onto his bed. Somehow, sleep was never a problem when he wasn't _supposed_to be asleep, and so, he quickly dozed off into feverish, strange dreams. None of it made any sense; things changing wildly and without any rhyme or reason, people he knew amalgamated into new individuals, words and their meanings disjointed and lost.

Then he woke up again. It was dark outside. He didn't feel rested and had no idea what time it was. The disorientation of waking up in the dark was very real, even with the streetlights outside casting a muted, yellow glow through the blinds. It didn't help that fall had just begun, the days getting short and shorter. Guessing what time it was wasn't easy.

He looked at his phone. Four in the morning. He'd slept for more than twelve hours. Sleep debt, probably - after all he'd slept less than four per night for almost a week. He knew this wasn't sustainable. Ari's body ached as he peeled himself from the bed, feeling cold the moment the blankets fell off. It wasn't only ruining his studies; it was wreaking havoc on his body. As an aspiring student athlete, that was almost the worst thing. He had several practice sessions lined up later in the week, too.

If the experimental drugs didn't work, he resolved to just dose himself up with whatever he could find. Something had to give. Anything would be better than this.

At least time passed quickly in that half-asleep state. Not as quickly as if he'd been properly asleep, but still; distinctly faster than when fully awake. He fluttered between that odd hypnopompic state and conscious worries about managing his classes, about affording his textbooks, and any other anxieties. No matter how trivial they were in real life, in that state, each one seemed like an insurmountable obstacle.

When his alarm actually went off, Ari felt surprisingly energized. It'd wear off quickly, but the promise of possibly fixing his problems went a long way in motivating him. He made his way to the building where the tests were to be performed, paused for a moment to collect his thoughts in the cold autumn air, and went inside.

There was nothing to it. In that aging room, he met a receptionist, who quickly ushered him into a small side-office along with a few other volunteers. Papers were signed and chemicals explained; this was, apparently, a novel molecule that had shown promise in earlier trials, and was approved for human testing. Almost certainly safe, the project leader assured them. All they'd have to do was to take a pill each night before bedtime, and then report back daily, six times via the phone and the seventh as a visit in order to collect a blood sample. And this would continue for two weeks. Some - half, in fact - would get a mere placebo. The others, the real deal.

Each participant was handed a nondescript brown glass bottle with their names on it. If not for them being at a university, the whole scene would've seemed terribly suspicious, but the implicit assumption that these highly educated people knew exactly what they were doing assuaged most of the volunteers.

And that was that.

Ari wasn't about to wait, though. He felt so giddy at the thought of getting a proper night's sleep - or a proper day's sleep, with how tired he was - that he made his way home immediately, swallowed one of the unassuming tablets with a glass of water, and laid down, paradoxically excited to fall asleep. Normally, that'd have been counterproductive. But in a few minutes, he was out like a candle.

A strange dissolution, a confused - but not unwelcome - sensation of being someone else, several others at once, the lines between identities and personalities blurring. As before. But it was him who was changing, now. Blissful disintegration and reconstitution.

Ari woke up once more. He stared at the ceiling for a while before realizing that he had, in fact, fallen asleep. It was dark outside, but the usual disorientation wasn't there. He felt a vigor that he'd been bereft of since his sleep issues started. It was wonderful! It didn't hurt that he'd have a good bit more spending money in the morning. Suddenly, everything was fantastic, and it'd felt like it all changed in a mere instant.

Those pills were amazing. Ari found himself laughing, a kind of bubbly giggliness welling up inside him. The next two weeks would be wonderful.

The first day indeed was so. The young man was absorbing information like a sponge in every class he took. Everything seemed brighter, a little more fun than usual. Almost as if he was a little intoxicated with some lingering effects of the sleeping pills. Positively sparkling with energy! He couldn't, he realized, wait to sleep some more, either. It was pretty funny; with a good night's sleep being so easy, it felt like another recreational activity, rather than something to be dreaded. The thought made him giggle as he made his way back home. He was a little itchy, sure, but that was probably nothing.

He effortlessly studied for a few hours, and even managed to get some exercise, jogging along the path around the campus for another hour. He did have his athletic career as well, after all, and now that he was feeling energized, the prospect of football practice on Friday seemed like something to look forward to, rather than dread.

He took another one of the pills and was quickly soundly asleep.

This time, that wonderful place of change and transformation was dark, like the woods in winter. There was pain, an ice-cold burning along his skin. He felt something else move amongst the trees, and soon realized - with some terror - that whatever was out there was him, as well.

Ari yawned. He didn't remember much of whatever he dreamt about; for him, each night was a second or two. The itchy sensation was getting somewhat maddening, only growing and growing, creeping along his spine. Has to be some kind of allergic reaction, Ari told himself. The itchy parts felt rough, too - he'd need skin cream. Still, it was something he could handle, not like the lack of sleep. Entirely worth it. Maybe it was from sleeping in one position for _too_long - it was hard to believe that sleeping too much was possible - so it didn't worry him too much.

He actually felt energetic even by the time he got back home after his classes. Normally he was utterly drained after some eight hours of learning, but not so today. It was amazing what getting a good night's rest did. He could scarcely believe it, still.

Ari ran into Eliazar on his way inside. Though he was good friends with his toned, downright sexy roommate, the intimate relationship that Ari had initially been hoping for had never manifested. Sadly, Eliazar - or Eli, as he was more commonly known as - was entirely straight. He was still good company regardless, even if it was rare that the two got to talk, at least after Eli had taken a night shift job to pad out his income. They talked for a little bit, though Eli was headed to work and only had a couple minutes to spare.

"...yeah, so I decided to join one of those experimental trials? The fucking sleeping pills one-" Ari mentioned.

"Oh, yeah, I saw that poster too. Never had issues sleeping, myself," Eli replied.

"Well it works, I'm actually sleeping damn well now-"

"Just be careful, could be some side effects since it's experimental."

"Yeah I might call them tomorrow, I'm a little itchy. Totally worth it though," Ari continued. "Anyway yeah, have fun at work."

"Yep, like always," Eli replied with a sarcastic smile. "At least it's a free workout," he said, flexing his biceps.

Ari seemed to remember that he worked in a warehouse. Maybe he'd ask him about where exactly, some other day. Though there was no denying that between physical labor and his regular gym schedule, Eli was about as fit as he could be. Not quite like Ari, himself, who'd never been quite as interested in staying in peak shape. He worked out some, sure, but he often found himself feeling a little too lazy. He was a little more... stocky, as he liked to call it, as a result.

He was starting to feel a little off, though. A little dazed. He found himself giggling a little, imagining Eli lifting boxes as a workout. And then outright cackling at the mental image before realizing that it wasn't actually funny in the slightest. Huh. He felt almost intoxicated, but it wasn't the pleasant buzz of being drunk; there was an anxious edge to it. Maybe he just wasn't used to sleeping well and didn't know what to do with all this extra energy. But he resolved to definitely call the doctors overseeing the trials, at least - if for nothing else, then to report possible side effects.

He thought about if he should take the next pill or not. Didn't medicines usually have disclaimers along the lines of "if you feel any itching, discontinue use immediately and contact your care provider..."?

There was a kind of dread building up in his stomach as he placed it on his tongue. The allure of a good night's sleep once again was just too strong, too seductive. What was the worst thing that could possibly happen, he asked himself, and then swallowed. Almost immediately he regretted it, knowing that he wasn't exactly following reason. Beggars can't be fucking choosers, though, he thought.If I stop, that's it for my studies.

He was out rather quickly. This time, there were no dreams at all; at least not until after he woke up. That was when reality stopped making any sense.

As Ari opened his eyes, he realized that a large part of his vision was obscured by some kind of thing attached to his face. Like the snout of some kind of animal. It was gone the moment he blinked, but the itchy sensation was all over his body now, along with feverish chills that came in waves, sweeping through him like a cold wind through flesh and bone. He was burning up, he realized. A fever. He caught a glimpse of himself in the mirror as he stumbled to the bathroom, but the reflection was nobody he recognized.

He tore his clothes off, only able to pray that his roommate wasn't home yet, or at least not awake. The itchy sensation had enveloped his entire body, growing like ribs from his spine, and he realized why, now, without the clothes to hide it away; his entire chest was covered with rusty red fur. Before he had the chance to think about it, his legs suddenly gave in, and he collapsed onto the tile floor, barely managing to brace himself before his head impacted with it. His feet felt swollen, pulsing out pain like a migraine.

They creaked_as he moved them, tendons swelling and _reshaping themselves, a cramping sensation in both his calves and arches sudden flaring up. He groaned, watching with morbid fascination as the heel was pulled up, sculpted by whatever was changing him. Every moment of it hurt, tears streaming from his eyes as the convulsive cramping wouldn't let up - punctuated by sharp snaps and cracks as every bone in his foot seemed to shatter, one after the other, to reconfigure in some alien way. The skin was growing rougher, he could see that much. At first, it was just rough skin, red and irritated. And then the red deepened, a kind of tingling distracting him from the pain for a brief moment as that skin became a pattern of scales. Reptilian. Out of place on a human's feet.

For a brief moment, Ari worried about how he'd could possibly walk like this. He knew that the moment he put his weight on his feet, the bones would shatter again, like brittle glass. But there were more changes to come, and before his eyes, his toes seemed to stretch, as if it reaching for something, curling and then splaying. Thickening, swelling, and lengthening into toes like those of a massive lizard.

Ari had a brief moment to realize that he still had his human toenails, barely managing to react in time for brace himself as those nails were uprooted, sharp claws tearing their way through the tip of each strange new toe. He was writhing, now. The pain wasn't as overwhelming as the earlier cramping, but it was impossible to ignore. Something warm ran down his sole, and he didn't dare to look. He'd felt that sensation before, at hospitals. Blood slowly coating numbed skin.

And then it was over, for the moment. The sudden absence of pain was so liberating that it nearly felt ecstatic. He felt thankful. He was panting, his feet red and black, disfigured, aching. Ruined. He'd have to wear some kind of wrapping over them, because no human shoes or even boots would fit.

Yet even as he worried, lying limply on the cold floor, there was a second kind of sensation. The burning pain, the impossible feeling being stretched, and the sharp cracking of his very bones lengthening and rearranging, it all faded for the time as the changes reached his hips. They all became a kind of pleasant ache, there. A tingling kind of arousal centring around his masculinity. Ari embraced the distraction. Eagerly so.

His eyes snapped open, vision still blurry with tears until he blinked. He was hard as rock, his cock jutting proudly from his crotch. Some part of him was enjoying this. It was a kind of perverse, shameful realization, but now that his attention was drawn to it, he couldn't deny the pleasant thrumming in his shaft. Each beat of his heart engorged him further, his cock darkening into a crimson hue of red before his eyes. Swelling a little further. And feeling good, so very good. Full of a kind of primal, masculine pleasure. Something powerful and seductive.

Soon his hips were moving on their own accord, thrusting upwards as the feeling of tightness and pressure grew. That was a kind of pain too, but a beautiful one, in stark contrast with the earlier agony, and he wanted more. He wanted to keep that feeling forever. Oh, it felt like his oozing shaft was being massaged by a pair of invisible hands, the pleasure cresting, doubling, and suddenly- suddenly as he watched, he had two cocks. No, two cockheads,_like a snake. Each a little smaller, at first, than what they'd split off from, but both feeling _wonderful. Dazed with that intoxicating blend of temporary relief and pleasure, Ari could only stare as his strange twin cocks bucked and throbbed. He imagined how good it'd feel to bury it inside someone. To rut into them until he pumped this corruption, this painful and beautiful gift into them, too.

As he admired that new shaft, bobbing before him, he could feel the pressure growing. Both in his loins and along his spine, a strange sensation that he knew, somehow, to be scales growing in, covering and consuming his skin. The feeling left his back arching, squirming and twisting, each little tingle shooting right down into his crotch. The itching had finally ceased, and the satisfaction of it was immense. Between aroused, shallow breaths and the mounting bliss all centred on his throbbing shaft, he almost felt thankful, like some sort of Stockholm syndrome. He welcomed the changes, each scale growing in, and each twitch of his beautiful new cock at least making him forget about the pain.

He was obscenely big, now. A swelling around the base of his shaft, like a knot. Little barbs like those of a feline around both tips. Fully in the throes of that carnal lust. And suddenly, he reached his peak. A gurgling moan spilled from his lips as his back arched, hips rocking and thrusting as if mating with an imagined lower, each motion both serpentine and animalistic. He felt his seed - the last of his human seed, he knew, somehow - surge from his engorged balls, up along his shaft. Erupting from the tip and splattering all over his stomach and chest in a river of thick, plentiful warmth. Blanking out all conscious thoughts but wanting to share that pleasure with someone. Both the pleasure and pain. To inflict this upon someone else so he'd not have to suffer alone.

Too soon, it was over, leaving him breathing heavily, painted with slick ropes of his seed, filled with a kind of satisfaction he'd never felt before. He felt his balls churn and pulsate still, quick to fill up with a new, tainted kind of cum, ready to infect others. He enjoyed that moment of respite, but a brief, temporary clarity robbed that blissful afterglow from him. Skewered it. The realization that none of this could be real.

Ari wanted to call the pharmaceutical department. To explain what was happening. But would they believe him? He could barely believe it himself. In fact, he half expected to wake up any second, strapped to a bed, screaming, in a padded room. What was happening wasn't possible; there was no way he could change like this from just a few pills, but it was happening regardless, in flagrant disregard to the few constant rules of the universe.

No. That was the key to it. It wasn't possible. He was still asleep, dreaming. A nightmare. A night-terror. That had to be it. Nothing of what he saw could possibly be happening.

But he barely had time to think about it before the pain started again, leaving the young man twisting and convulsing as if being electrocuted. Maybe that was what was happening. It was almost a relaxing thought. He was delusional. He was being executed, yes, without realizing it. Soon he'd feel nothing at all.

No. It was still a horrible dream. He had to end it, somehow. Taking another pill, his terror-inflamed mind told him, would do it. He'd fall into quiet, dreamless sleep and wake up happy in the morning, not remembering any of this. But even if it was all mere illusions, he couldn't stand up, couldn't will his legs to support him.

And so, Ari crawled, even as the changes continued up along his body like rot growing up the trunk of an old tree, hollowing him out. Each motion was agonizing, but he managed to pull himself along with his arms, over the bathroom step, over the living room floor, and into his bedroom once more. By the time he got there, he was pushing himself along with his legs instead as the changes took hold of his arms, robbing him of control. He could feel - but mercifully not see - blood vessels pop and burst as his muscles swelled, the red fur sprouting along his arms. No! He was crumbling. He had to do- had to get out. To stop this.

He managed to knock over his nightstand, and the pills with it. Did it fall in reality? He didn't know. But he managed to feel out one of the pills with face. He spat out a tooth, and then another, using every ounce of willpower to chew up his one way out, and then swallow it with a mouthful of coppery warmth.

It took him, mercifully, away from the pain and fear. His last, thankful thought before unconsciousness was that he'd at least not remember any of it.

Reality would have no such mercy on him.

The pain was gone when he woke up again, in a pile of detritus. Discarded skin that his new body no longer needed. Hair. He flexed his curved, razor-sharp claws that'd grown in during his absence.

His body was entirely covered by red fur, and in some places, black-splotched scales. The fear was gone. The abhorrent transformation had, after all, spread throughout him with little resistance. This was _him_now. Ari twitched as his body slowly woke up, lagging after his mind by a few minutes. Strange sensations of numbness behind him. Like an arm that'd fallen asleep. He rolled over, letting his tail uncurl. He recognized that it was new, certainly, but it felt like a natural part of him.

The fear might've been erased, but there was a kind of dread hanging over his thoughts, a bitter sense of wrongness from whatever parts of his brain that hadn't succumbed. Maybe they never would, leaving him in this state.

He couldn't recognize what he was. Part something canine - hyena? - with reptilian features. Like that beautiful cock. Ari grunted, struggling to his feet. His body felt sinewy, full of power, though burdened by strange growths. His chest felt heavy, his neck heavier. He finally found the mirror and what he saw made his blood run cold.

Hyena, yes. And seemingly, cobra. He had a serpentine hood, permanently flared, giving him an almost regal appearance. Regal and hideous. He had the snout of a hyena with pronounced tusks. An obscenely large set of genitals between his legs. A pair of breasts, halfway between male and female. Oozing with something white. Milk? More nipples beneath those. Each detail he noticed made his head swim, his eyes tear up. Had he believed in demons, he would've guessed that. Something like Baphomet - but no - a mutant.

Something had gone seriously wrong. The pills. He'd never fit into society again. He'd end up alone, so unfathomably alone, or dissected in a blacksite laboratory. Yet, as he stared at his horrid reflection, the impact lessened. Step by step, he was beginning to see himself rather than a warped monstrosity. He couldn't deny a certain beauty, with dark red fur and black spots, the lethally sharp claws adorning every fingertip. The way his musculature had grown thicker and wirier, more defined, bulging with a bestial kind of potency along his arms and legs, every inch of his body feeling so very strong. Coiled. Like a snake always ready to strike.

And that predatory feeling was complimented, he thought, by the almost feminine bounty of his new chest, and the plump, virile sheath between his legs, heavy balls churning with seed. Both eager to be put into use. It was horrible, yes. Horrible and beautiful in some twisted way.

Something, at least, was familiar. That sweet pressure between his legs. A primitive kind of lust. His new body wanted him to mate. Not only mate, but to nurse his partner, to share his state with someone. The idea was abhorrent, and at first, Ari's shaken mind protested, reeling at the idea of inflicting this curse on someone else. He should disappear into the forest and never be seen again, he understood that much. This hand to end with him.

But wouldn't it be better if he had just one like himself to share the wilderness with?

Someone who wouldn't recoil and retch when they saw him?

Someone who'd eagerly position himself, begging to be filled with his tainted seed?

No. He was a monster on the outside, yes. He couldn't allow himself to think like that. It was disgusting. He knew, on some instinctive level, that this condition was infectious. It wouldn't stop with him if he let those urges take control.

But Eliazar would be home soon. Ari had always wanted to fuck him. And now he could, effortlessly. He could share that corrupted lust with his roommate, finally.


Eli had noticed Ari acting a little strange. He chalked that up to a combination of sleep deprivation and those odd pills he was using. That was more or less to be expected, right? At least it was being supervised by professionals.

He finished up his shift at the warehouse, muscles aching from exertion. Free workout, as he used to say. Paid workout, even. He couldn't imagine doing this for much longer, far less for the rest of his life, but for the remaining year of college, he figured his body could take it. He had all kinds of plans that'd all come to fruition soon, and working in manual labor had only strengthened his conviction. Raising the minimum wage would be the first thing he'd campaign for. That, and a whole lot of other things.

He'd always cared a lot about other people. That's why he'd become a politician. But that was also why he couldn't stop thinking, even worrying, about Ari. Usually those experimental drugs were safe, but he'd heard some horror stories, and he wasn't a fan of those waivers and contracts they signed. Devious little pieces of paper, supposedly absolving the researchers of responsibility, both moral and legal. As such, he decided to check on his roommate when he got home, even though all he really wanted to do was collapse into bed and skip ahead to the next day.

Their home smelled strange. That was the first thing he realized upon arriving. The second was that it didn't just smell strange, but rather, musky. Sexual. Like how he imagined something primal and fierce might smell when aroused. A raw, unfiltered kind of sexuality that made his eyes water. He couldn't begin to guess what'd cause it. Ari had never been the type to bring hook-ups to their shared apartment. Much less have orgies, which was about what it'd take to cause this kind of stench. There was an alien kind of edge to the thick fragrance, though. It didn't quite smell like anything he'd smelled before. There was a deeper quality to it, something just at the edge of his perception. Something that made his sinuses tingle as he inhaled it, left his lungs feeling warm, and that warmth suffusing into the rest of his body.

Huh. He realized he was getting a little excited. Good thing he was too tired.

Eli knocked on Ari's door. No answer, of course. He was probably asleep, though as Eli put his ear against the cool surface of the door, he couldn't hear anything. Ari almost always snored when he finally fell asleep. Maybe he wasn't home.

He turned around, and it took him several seconds to realize what he was looking at. At first, his mind refused to accept what his eyes were viewing. As if trying to protect his sanity. But he couldn't look away. The tragic creature looked like something between a fantasy creature and something that slithered out of a laboratory. Twisted, like something that could almost exist, but its muscles defined enough that Eli knew he had no chance. Drool ran from the side of its mouth, along the protruding fangs, as it stared at Eli with eyes black as coal. And going by how its cock slipped free of the sheath dangling between its legs, coated with a musky kind of slime, it liked what it saw.

And while Eli wasn't one to succumb to panic, normally - considering himself to be rather stable and fully in control of his faculties - when the creature rasped his name, his senses left him.


It was damp. Damp and cold, with a smell of mildew in the air. And something warm and slick was wrapped around him. Eli opened his eyes and couldn't see anything, but he felt what must've been a tongue tracing along his body, hot and humid breaths washing over him. He was still with that creature. It'd dragged him somewhere. It couldn't be far, maybe one of the empty historical buildings on the campus - some forgotten basement somewhere?

The tongue dragged wetly over his bare chest, into his armpit, and then coiling over his nipples, moments before that slobbering mouth latched onto his chest, suction tugging at his nipple. Its saliva tingled where it covered his body. Eli recoiled, but there was nothing he could do with the creature's arms holding him in place.

"...awake," it hissed. It said more, but that was the only Eli could make out, the rest a slurred series of hisses and growls, its mouth not built for human languages.


Ari wanted to stay curled up with Eli forever. He was trembling so. It was a little cold, and he tried to keep his roommate warm as he slept. Once he woke up he'd never have to feel cold again. He'd be just as warm as Ari was.

"Finally you're awake," he said, as he felt his roommate stir. To himself, he sounded perfectly normal. "You passed out earlier. Rough day at work?"

Eli didn't respond. Maybe he'd hurt himself when he fell? No, no- just thinking of pain made Ari's vision blur. He'd felt enough pain. At least right now he was all comfortable, even feeling something akin to pleasure. He was hard as rock and pressed against Eli's thigh, but that was only the natural reaction when close to someone he wanted to make into his mate.

Unlike the human, he saw perfectly in the dark. Saw Eli's poor eyes blindly flick across the room, seeing nothing. He'd torn open the basement of the old biology department, since turned into a museum of sorts aboveground, and the tunnels beneath it sealed off and forgotten. That's where they'd make their nest for now, only venturing out once both were confident enough that they could make it out of the city without being seen - or at least, without being stopped.


Eli couldn't see, but he could feel. He could feel every inch of that creature's body. The disgusting arousal pressing against him. He was naked. It'd stripped every scrap of clothing off of him, and between his thighs, that cock throbbed eagerly as the beast suckled on his nipples, as if trying to coax milk out. Milk. He could feel the mutant's own milk ooze and drip, feeling warm as it splattered onto his belly. There was a vague sweet scent to it, mingling with the mildewy, stale air, and that overbearing masculine musk.

What was it going to do to him? He struggled, squirming and kicking, managing only to move enough find himself pinned between cold, aged concrete and the heat of the creature above him. "Let me- let me fucking go," he screamed, his feeble attempts at punching the creature amounting to little more than slaps, his fingers slipping off the slick scales or tearing out loose fur as he tried to get a hold on its body. And then he felt it, a hairless patch along one of its arms, exactly where Ari's old scar was.

This thing had, once, been his friend.

"Ari! Stop! It's me, Eliazar!" he cajoled the creature. Maybe if he could remind him of what he really was, he'd snap to his senses.


Ari felt so worried about his friend. He seemed to be in so much distress. If it wasn't for his predicament, he'd have called an ambulance. Maybe he had hypothermia? He kept struggling, kept repeating their names as if Ari didn't already know. Ari was trying so hard to keep him warm and comfortable. Oh- suddenly he realized what he could do. If he couldn't hold his friend sufficiently warm on the outside, he could fill him with heat. That sweet warmth that gushed from his plentiful nipples. That'd make him feel better.

His newfound body approved of that idea, his cock twitching as another splash of precum surged through it. He coiled his arms around Eli's struggling body, cradling his smaller form against his own, as gently as he could. Soon, he'd understand. Ari hoped it wouldn't be as painful, as it had been for him. Nh. No pain. He had to do it, though, for his sake.

Ari forced Eli's mouth open with a pair of thick, meaty fingers, and then, cupping a palm behind his adorable head, forced that mouth against his leaking, bountiful breast, sighing softly as he held him there, letting his milk flow into Eli's mouth.


Eli almost gagged when his mouth was forced onto that stiff, damp nipple. It wasn't that it tasted bad - the milk was warm, and had a kind of sweetness to it - but he was afraid, on some level, that if he drank any of it he'd change too. The instinctive revulsion was to something that was inherently wrong, something probably contagious, like seeing someone horribly sick and wanting to keep a distance. Yet, here he was, with a mouthful of that vile, warm stuff_._ He couldn't move his head in the slightest, not with what'd once been Ari's strong hands holding him in place, but at the very least, he wasn't going to suckle, or swallow.

It tingled in his mouth, over his tongue, as if it was laced with the chemicals that'd cause Ari's changes to begin with. Maybe it was. Or maybe it's corrupted his very body into something that'd twist others in turn. Force their bodies into new, unnatural forms. How much of it was he absorbing already? He was starting to feel warm as more milk drizzled into his mouth. The cock pressed against his ass bucked again. Ari was enjoying this, this perverted nursing.

"...drink," the creature rumbled. Eli imagined it looming over him, a smug grin on that animalistic face, knowing that he'd not be able to resist for long. Already his throat was starting to feel dry. Each time he breathed in, he got a lungful of Ari's musky scent, his nose buried in that soft fur, right next to his armpit.

He felt some of the milk drip down his chin, and realized his mouth was full. He couldn't spit it out. But he wasn't going to swallow, either. He wasn't going to condemn himself to become like this disgustingly sexy creature that was trying to turn him.


The poor thing wasn't drinking. Maybe he couldn't. Maybe he was too cold to, despite Ari's best efforts. Oh, he cared so much for his friends. He'd help. Ari tightened his grip around Eli's head, and then pinched his nose shut, gently but firmly.


Eli struggled as he suddenly realized he couldn't breathe. His mouth was full of that sweet milk. Two choices were apparent in his panicked mind. One was to drink, and accept whatever consequences. The other was not to, possibly die from inhaling it, and have the monster "feed" him anyway while he was unconscious.

Blindly, he pleaded for Ari to let him go. Even as the strength was sapped from his muscles, he tried feebly to push away. And then, tears in his eyes, he swallowed, letting the warm, tainted milk flow down his throat, filling him with warmth. Warmth that quickly seemed to dissolve that gnawing feeling of dread in the pit of his stomach.

A kind of relaxation suffused him. Maybe this wasn't too bad. The warmth seemed to flow through him, gathering in every sensitive spot on his body. His cock stirred between his legs. Eli weakly tried to resist it, but he found himself too dazed to cry, too dazed to fight that swelling from growing, displaying his submission to the creature holding him.

He realized that he was suckling on the beast's teat now. Drawing more milk into his mouth, losing himself in that moment as he now freely allowed the heat to fill him. It was too late, anyway. His hips bucked as his cock throbbed into full hardness, while Ari stroked the back of his head reassuringly. Full hardness, and... more so. Beyond his normal size. His balls felt so very swollen.

A sudden stabbing pain somewhere behind Eli's eyes made them snap open. He realized that he could see, now. He saw perfectly well in the darkness, and found himself gazing up at Ari's black, hyenine eyes. His mouth came off his breast with the wet pop of suction breaking. It didn't matter; he'd drank too much of it already. The changes were beginning, parts of his body suddenly feeling painful, like the experience of a budding flu. And as it had with Ari, it moved from bottom to top.

Eli fell onto the cold concrete as his legs and feet simultaneously cramped, so hard that he could imagine his muscles bursting and tearing under the sudden force. He could almost hear it happening, a strangled cry of agony bursting from his lips.


Oh. It'd started. Ari was determined to let his friend feel as little pain as possible. So he was instantly there, hoisting the trembling human onto his stomach so those changing paws were facing him. He'd make them feel better.

His long tongue was there an instant, lapping over Eli's rough soles to alleviate the pain. It wasn't that he didn't also find the act rather erotic, his cock now grinding against Eli's chest. He wrapped his muzzle around a toe and suckled on it, twirling his tongue around the nub and helping it swell and twist into whatever new shape it was always meant to have.

He was fascinated by how the first of his toes barely changed at all, the nail sharpening into a claw but not much beyond that. The second, third and fourth toes, though, startled even his hazy mind. They began to feel almost sticky against Ari's tongue, pressing into each other, and then fusing. Ari realized what was about to happen and held Eli's foot still as the three bones merged into one. Joints cracked as segments of his toes slotted into each other. Like busy lanes at an intersection. Like-

Helpfully, the hyena-snake swallowed down the gush of blood as one enormous claw burst out from that joined toe. His friend was becoming something entirely different. He continued lapping, lapping, lapping, trying his hardest to take the pain away.


Eli was in agony, but with each wet, disgusting lick along his changing feet, the pain seemed to go away, or at least fade for a moment. And so he pushed his feet against Ari's face, desperate for any kind of relief.

The strangest, most perverse thing about it was that he couldn't deny that it felt good, too, as the changes swept up his legs, leaving him covered in brown, almost comforting fur that quickly left him feeling warmer. Doubly so when that pelt reached his groin, like an oddly sensual hug and squeeze around his growing cock. Soon he was bucking his hips too, just like Ari had been, in the throes of both pleasure and pain.

Unlike Ari, though, he wasn't alone.

The moment those urges began to manifest, the hyena was there, letting go of Eli's feet to instead wrap his meaty fingers around Ari's cock, squeezing and pumping it. Encouraging him to just give in and enjoy the moment with each slick motion of his hand. Eli could only moan as he felt his lover- no, friend, give a snaking lick around the leaking tip of his cock, scooping up precum and whatever else wetness was forming as his shaft grew an inch, and then another, each heavy throb leaving it feeling a little bigger, a little more wonderfully masculine.

His thoughts were getting cloudier, but he had only received a secondary dose of whatever caused those mutations, rather than a direct and far too high one like Ari, and as such, there was more pleasure to it. He realized that he was rutting into the teasing grasp another male - at least one_mostly_ male, he still felt that milk on his lips - that his twisted, amalgamated form was growing attractive.


His friend was almost there, Ari could tell. He just needed a little more encouragement. The beast watched as sharp claws burst out from Eli's fingertips, shredding flesh that almost immediately knit itself back together, as he pumped and stroked his cock, doing his best to milk the pain out of his writhing friend. The fur had spread all the way to his neck, now, slowly consuming the rest of his human appearance. It was only when his nose and ears began to crack and stretch, nearly rendering Eli unconscious, that Ari recognized what he was turning into; a kangaroo. And not a monstrous hybrid like himself. A beautiful, virile, anthropomorphic kangaroo. Oh, he'd make such a beautiful mate.

Mostly, at least. Ari leaned down to slobber over his soon-to-be partner's cock, letting his tainted saliva soak into it. Why should he have to settle for a plain shaft when he could have everything, letting each partner experience utter rapture as they impaled themselves on it?

He teased the head, sculpting it between his fingers until he felt the rasp of barbs against his hands. Rrh, yes. Those would feel fantastic scraping and scratching his next conquest. He moved onto the very base, rubbing small droplets of his milk into the reddening skin until it began to swell further, a knot slowly growing in. That'd be perfect for ensuring that whoever he rutted ended up changing as well, sealing in every drop of his cum. There'd be a lot of cum, too, seeing how large his balls were getting.


Eli saw a muzzle the next time he opened his eyes. The pain had ceased, except for a discomfort at the base of his spine, like a massive pillow stuck underneath him, leaving him at an uncomfortable angle. He rolled over, breathing a sigh of relief. As his enormous tail uncoiled. He didn't recognize what he was, at first, not with the clawed hands and feet. An otter? No, he lacked a distinct nose. A kangaroo?

His mind reeled at the realization. He wasn't human any longer. That roiling chaos of emotions seemed to still as he turned his head and found himself staring right at Ari. He was beautiful. But Eli wasn't attracted to males. At least he hadn't been. But he was hard as steel, a few drips of precum running down along his shaft as his eyes fixated on that beautiful yet strange cock bobbing with need between the beast's legs. Suddenly, he wasn't so sure anymore. His urges all told him to push his ass up and raise his tail to show his thankfulness. Ari had stopped the pain, after all. The fact that he was also the cause of it didn't seem to register as strongly.

This body yearned for that cock of his, either way, clenching with need. He could feel his friend's - his mate's? - eyes on him, dominant and demanding. Eli could do nothing but obey. Obey those instincts to offer his virgin ass for the beautiful monster to pump his love into. He fell to his hands and knees and raised his tail.

Ari replied to his gesture with a throaty, hissing growl, and was on top of him in an instant. "Rrrh, no," he rumbled. "I want see you."

Before Eli could even process the fact that he understood his partner now, he was flipped over onto his back. He could barely feel the damp, cold basement floor now, with his coarse fur covering every inch of him. Every inch, except for that turgid shaft between his legs that flagged his arousal for anyone to see.


Ari oozed with slick, slimy precum as he hoisted the kangaroo's legs onto his shoulders. Finally, he would get to consummate his love for Eli. Even the shreds of his conscience rejoiced as his twin cockheads kissed that warm, puckered entrance. Gods, he was going to breed him. Over and over again. To rut away whatever straightness remained in that adorable head of his until he was just as eager as Ari to bring every nearby male into their little lair.

His hips bucked. One of his barbed heads slipped across Eli's tight, quivering ring, rather than plunging into it, at first, and those barbs in turn scraped the tender flesh. Eli squirmed, breathing a pained groan, but his cock throbbed. At this point that pricking, tugging sensation would be nothing, not after that transformation. If anything, it should only heighten the pleasure.

He reached down to squeeze his two shafts together. They'd never have fit into Eli when he was still human, but his infection had left his ass puffy and gaping, a little cocksleeve made to be sunk into and creamed. And so he did, with a sharp thrust. Ari felt his beloved friend stretch around his shafts, and there was a tearing sensation as he buried his cock deep. Eli's body was still malleable enough that it sculpted itself around that barbed intruder, hips widening ever so slightly and his hole stretching more than should've been possible. The base was even thicker as the rest, a knot slowly swelling in preparation of tying the two together, but somehow, his friend still squeezed around it just as tightly.

And from the expression on the newly minted kangaroo's face, it was pure bliss. Ari began to rut into him with heavy thumps, snarling and grunting with each clench of that tight, heated body around his shaft. God, yes. He needed it. Needed to drain his over-full balls into that tight, clutching orifice. Eli's entire body was formed to be his. To belong to him, to accept his seed. He growled possessively as he sped up, pistoning into that receptive hole with a singular goal in mind.


It was a strange experience. Having someone's cock inside him like that, especially one so girthy. Eli realized, in the throes of passion, that he liked it; needed it, each thrust cementing Ari's claim on his body. He felt empty each time he withdrew, and sang out in ecstasy each time he sunk back in with a buck of his flexing hips. His body burned to be fully claimed, to be filled, and he was already clenching around every inch of that wonderful, hot shafts inside him, almost possessively, trying his hardest to make it pump that sticky blessing of mateship into his demanding depths.

He gave a surprised whine when Ari suddenly buried his muzzle into his armpit, first nuzzling and then licking, feel him sniff and huff as he took in Eli's new, more primitive musky scent. His long tongue snaked over every sensitive inch, saliva soaking into the short fur.

"Mine," he growled, his thrusts growing faster.

"Yours," Eli replied, between those moans he couldn't help but let out.

He wrapped his long, powerful legs around Ari's waist, feeling his muscles tense with each thrust. It was wonderfully erotic. Knowing that his own body was causing every tremble and every jolt of pleasure that Ari was feeling. He wanted to be a good mate, a good cockwarmer, a good bitch in heat, countless fantasies of being creamed over and over again until his fur was wet and matted all the way down to his toes.

Ari sped up further, hammering into Eli's wanton hole with passionate, feverish abandon. He changed his angle ever so slightly to get as deep as possible, and in doing that, his throbbing maleness bumped right against that hidden pleasure-button deep inside Eli's body. The fragile remains of his composure were shattered instantly as every nerve in his body sang out in bliss. He came, splattering his belly, chest and even face with ropes of thick cum, squirming and thrashing in the sheer intensity of it. How could he ever have been straight if getting rutted felt this good?

Some of his cum landed, wet and hot, on his muzzle, as well, and he instinctively lapped it up between loud, needy moans as his body trembled in orgasm. It tasted like pure, raw sexuality, and he clumsily scooped up more of his spent seed only to lick it off his paws, as if it was the best thing he'd ever tasted. Maybe it was.

"Mine," Ari repeated, and Eli could feel his cock swelling inside him. And suddenly he was stuck, those thrusts growing every short and fast as his knot locked inside Eli's body. The barbs flared, digging into his inner walls as he hilted himself. And he felt every heavy throb, accompanied by a spurt of warmth inside him. Again, and again, that liquid heat seeping into every nook and cranny in his body, claiming him. Seeding him. Eli held himself flush against his mate's groin, encouraging him to spill every drop of cum as deep inside his needy depths as he possibly could, luxuriating in the sensation of being so heavily bred. He drank in the sensation eagerly, letting his thoughts fade away into a floaty, dazed bliss.


Ari pulled out with a wet squelch, a gush of his thick cum following from Eli's gaping ass, snapping him back into reality. He curled up around his new mate lovingly, his half-snake body far more flexible than it should've been.

Eli, meanwhile, found the reality of the situation sinking in. How he was changed, permanently so. He'd never fit into society again. He couldn't deny that the warm cum pooling inside him felt wonderful, though, and he latched his mouth onto one of Ari's still milk-laden, muscular breasts as he wondered.

He didn't want to remain with Ari. He knew that much, as he let that sensation lull him to sleep. No matter how good it felt. But if he didn't, he'd be alone, entirely so; there was nobody else like them out in the world. He shook his head as pleasant, erotic images of changing that flashed through his mind. He could change that, if he wanted. All he'd have to do was to mate with someone, and they'd become just like him.

It wasn't like he'd be the same as Ari. He was still sane, and as long as he had at least some company, he'd remain so. Maybe it wouldn't be too bad. After all, having that powerful, soft, bestial body felt good. It felt warm, strong, wonderfully erotic. Would it really bad that bad to share that feeling with somebody else? Some other cute student? They could take turns fucking each other until his partner was transformed too.

No, it wasn't right. He couldn't do that. Yet, the thought made his cock throb with need, eager to be put into use. He was fantasizing of sinking his shaft into a human, of filling them with his tainted, infectious seed, like some mindless animal claiming a mate for himself, and it felt good.

Maybe it wouldn't be so wrong.
