“Be careful with those samples, Colin.” The serious face of Dr. Marcellus Alifel bore down on the wispy student researcher carrying a tray of colorful liquids in beakers, nearly startling him into dropping them.

“I am, I am!” Quickly Colin gathered himself and set them down on the table, wiping his brow. A mousy sort of male, barely topping five and a half feet and 110 soaking wet, freckled and bespectacled with cleanly-kept blond hair, he seemed very much at home in the stuffy lab environment. And he was, for the most part, except when the pressure was on. “I know this stuff is important to you…”

“Exceedingly important, of course! But also exceedingly important that they don’t fall into the wrong hands.” Dr. Alifel swept by, dropping a tray of plastic bottles onto the lab table next to Colin. A balding man with hair that was rather wild and unkempt, a wrinkled face with somewhat caricaturish features, a matter that was impetuous and stiff and just a little bit cracked...yes, he had the appearance of a mad scientist, enough that he had a reputation for being the ‘kook’ of the university’s extensive sciences wing. And, if Colin was right about what those liquids entailed, he was definitely leaning into the role…or, perhaps, dropping like a meteor into it.

Colin wasn’t complaining, though - he was getting course credit and pay for this, mainly because Dr. Alifel needed to offer both to get ANYONE to take based on his reputation. Everyone said he was into fairly weird stuff, tampering with forces no one should, playing god, trying to create the next Frankenstein (and rarely did they make the differentiation between Frankenstein and the monster they were actually talking about). He was warned that he would be an experiment, that he would be fed to monsters, that he was at risk for all sorts of unpleasant fates if he chose to work for that nutcase.

Colin had been working for Dr. Alifel for six months now, and he could state, with the utmost confidence, that they were only partly correct.

As the liquids before him were evidence of, as he started to transfer them into the plastic bottles, which were already half-filled with clear liquids of some sort. Which looked suspiciously like they had been pulled from someone’s recycling. “Sir, are you sure there are appropriate containers for these?”

“I spent a good deal of time sterilizing them and testing them for contaminants, they’re clear. As if I could afford to spend nearly $5000 on specialized vessels, they think the university just SHOWERS me with money…” Dr. Alifel was rather dismissive of the concern, though Colin was used to that. And as always, the best way to deal with the quirks of Dr. Alifel was to go along with them…Colin knew by now that if something went awry that wasn’t provably his fault, Dr. Alifel wouldn’t lay into him for it, he’d just move on. Despite everything, he was more easygoing than he presented, at least as long as it wasn’t actually something Colin screwed up. Even then, though, a brief spurt of yelling was usually followed by calmness and a chance to rectify the mistake.

He was careful not to spill as he poured one beaker into each bottle, watching as the differently-colored liquids paled slightly as they were somewhat diluted; all of them were rather bright and eye-catching colors, dyed that way to be more obviously weird. Not that they needed much help being weird, in Colin’s book - their purpose was weird enough as it was, and the fact that they even existed was mind-boggling.

Dr. Alifel’s research was, indeed, quite kooky, and this was where the ‘partly correct’ came in - he was indeed toying with pretty monumental things. And the thing that he was most invested in was a bizarre discovery that had been made overseas, following a meteorite impact that had made sensational headlines all the world over. It had thankfully not come down anywhere particularly dangerous, which was especially good because it wasn’t tiny…not big enough to cause a mass extinction by any means, but big enough that a few acres of forest had been leveled, which could definitely have been a city block or so. But that wasn’t the real big news…the real big news was that scientists had discovered some kind of bizarre microscopic life from in the remnants. It had somehow survived the cold of space, the heat of entry into Earth’s atmosphere, and the raw power of the collision with terra firma, and that had a lot of people curious about it.

Dr. Alifel had been curious as well, and he’d procured some samples for his own studies. And he had discovered that they reacted to DNA samples from earth creatures, multiplying and producing strange byproducts, many of which resembled some biological compounds. Colin was working on transferring them into bottles which had some basic sugars and growth media, which would allow them to multiply and proliferate more quickly and perhaps produce large enough quantities of these compounds that they could be more easily studied and analyzed. Various animals had been used, samples having been obtained by means that Colin didn’t want to know about in case they were shady…they had to be somehow, it wasn’t like he was using lab rats or monkeys, he’d procured DNA from crocodiles, sharks, rhinos, eagles, and dolphins among other things, and Colin knew none of those were animals local to their region. But even beyond that, Dr. Alifel was convinced that this bizarre life-form could potentially be some kind of evolutionary trigger, something that could perhaps make these animals far stronger and more capable if applied to them…something that seemed dangerous to contemplate to Colin, since most of these animals were fairly dangerous to begin with.

That, however, wasn’t something he had to deal with at the moment. He was just helping to get the samples into their propagation bottles, what happened with the byproducts wasn’t on HIS head. And Dr. Alifel wasn’t quite to the application phase yet anyway - he wanted to know more about the workings before he started active experiments. And Colin was hoping that he’d be long gone by the time THAT came around.

He’d just finished closing up the last bottle when the door banged open, making him yelp. “Hey-o, nerd-bro!” boomed a loud, boisterous voice that had Colin’s heart sinking. Oh, fuck, you can’t be serious, why is HE here?! He would have liked to pretend it was just a bad dream, but it was hard to deny reality when it was stomping up loudly to him, in a thick and muscular body glistening with sweat and barely covered in light athletic wear, with the shortest-cut brown hair he could get without just shaving it all off, it seemed like. “Oy, you working on your weird science shit right now? Hah, cool stuff, bro.”

God dammit, Barry.

Colin was unfortunately a little too familiar with Barry…he was roommates with the lunkhead. The universe’s cruel joke played on him, pairing the small nerd with the big jock…Barry had a good foot on him, probably weighed twice what Colin did, and had a quintessential musclehead approach to life. Okay, he had to admit that, personality-wise, it could have been worse - Barry was thick and did poke fun at him, but he at least seemed to respect Colin, which was more than his previous jock experiences. But he was just so LOUD, and an annoying kind of loud at that, and he seemed to be incapable of reading the room, occasionally being wildly inappropriate and not getting how. Colin mostly just put up with it because it was nearly impossible to get a transfer these days, and he couldn’t justify it by saying that Barry was doing anything malicious to him.

Still, the lab was supposed to be a refuge…this was certainly NOT the case now. “Barry, what are you doing here?” he asked through clenched teeth.

“Eh? Oh, yeah, bro, was lookin’ for you. And hey, I found you! Didn’t even think I could find this crazy-ass science den!”

“Excuse me!” Dr. Alifel suddenly rushed in, looking frazzled. “WHAT on earth are you doing in my lab, you troglodyte? We have important work going on here, I have no need for uneducated idiots mucking things up!”

“Whoa, whoa, chill out, bro.” Barry seemed a bit surprised but not enough to rattle him. “Just checkin’ in on my buddy Colin here! You’re working him to the bone in this heat, don’t ya think? Seems like he could use a nice pick-me-up.” He smacked a bottle of some sports drink on the table, in a grungy unlabeled bottle; the color of it seemed like it would fit with their experiments, a weird deep green that he didn’t think meant it had lots of healthy vegetable in it. “All yours if you want it, bro.”

“I’ll…pass, thanks.” Colin stood up, gently pushing Dr. Alifel away from Barry. “Sir, please let me take care of this…I’ll try to make sure he doesn’t come back in.”

“You know him?”

“You remember how I’ve spoken about my roommate? This is him.”

“…My goodness…I didn’t realize it was THAT bad.” Dr. Alifel scowled at Barry, who just grinned back. “I rue the day folks like YOU were given the grace to enter an institution of knowledge and learning like this, with no interest or ability whatsoever. Clearly we don’t have enough low-brainpower jobs if they keep trying to make something of you.”

“Tsh. Sticks and stones, bro, sticks and stones.”

“Please, sir, I’ve got this.” Colin more wanted to get Dr. Alifel out before he said something that got under Barry’s skin…not much did, but if anyone could find it, it was Dr. Alifel. Finally he relented and turned and left, albeit reluctantly, and Colin could get back to getting the other person out of there. “Barry, nothing was so important that it couldn’t wait until I was back.”

“Dunno if I’d catch you, bro, I gotta hot date tonight,” replied Barry with a wider grin.

“Oh, joy. Please tell me she has a place for you to go back to, so you don’t come back to OUR place.”

“Nah, but if we hit it off, I’ll find a nice private spot out there somewhere.” Whether or not that was a good idea, Colin didn’t care, because anything was better than having to listen to his roommate pounding pussy while he was trying to sleep. The fact that Colin was gay didn’t help that, either...Barry didn’t know that, of course, Colin wasn’t going to take a risk of revealing that and having things fall apart, he didn’t KNOW if Barry was that kind of person but he couldn’t take the chance. “Mail girl said that package ya were waitin’ on came in today. Figured you wanted to know since you’ve been asking after it for like five days now.”

“THAT’S what you came here for?” groaned Colin. “I would’ve found out, since you know I’ve been asking daily!”

“Yeah, but you know how they are in the mail room, just kinda not all there, yanno?” Guh, I know TOO well, I’ve lived with you for months. “Anyway, that’s all I gotta say, and I gotta good run ta get back to. Later, bro!” Barry snatched his drink off the table and trotted out, oblivious to the obvious boundary breach, as he often was.

Colin let out a deep sigh, rubbing his head. Of all the places for him to show up…I’m going to have to talk with him, make sure this doesn’t happen again. Mmph, who am I kidding, it’ll happen again if he wants it to happen again…maybe I can make him not want it to happen again. “It’s all clear, sir,” he called into the back, letting Dr. Alifel know he was safe from jock cooties.

“Finally…” muttered the professor as he emerged back into the lab area, looking plenty disgruntled. “I’m going to have to decontaminate. How DO people like that get past the gatekeepers here? Is neanderthal brutality truly so valuable to them that they would reward nudniks like that with the prestige of alumnus? How far academia has fallen…”

Colin kept his mouth shut; Dr. Alifel was perhaps being a BIT over the top, in his opinion, but he knew better than to say that to the professor’s face. He HAD been far ruder to Barry than Barry had been to him, though…perhaps that would provide Barry with a bit of incentive to stay away. He sighed as he gathered up the bottles and placed them onto a tray, preparing them for transfer to a controlled environment to sit for a bit and let the compounds proliferate. Colin had seen plenty of them already, but Dr. Alifel was ever so interested in the differences between samples…apparently there had been a fair bit of variation in some of the findings, so it seemed like this was at least warranted.

He was just about to pick up the tray when he paused. One of the bottles looked a fair bit grungier than the others. “Sir? I think one of these wasn’t cleaned properly.”

“Impossible, I cleaned them all. Perhaps that grubby goofus got his paws all over it.” Dr. Alifel swept over to examine it. “Oh, for goodness sake, it’s filthy! Rgh, he might have contaminated the entire sample, I’ll have to prepare another vial…wait…” Colin felt a bit of apprehension as Dr. Alifel scrutinized the bottle more closely. He was starting to pick up on it too…the fact that the bottle wasn’t quite a match for the others in appearance now, either. “This…this is that nudnik’s…whatever you call it, dimwitade or whatnot. What’s it doing here?”

“I don’t know! He grabbed a bottle, I saw him…leave with it…” Colin’s eyes widened as it hit him. “Oh no…the crocodile sample…”

“He…took the sample, didn’t he?” Dr. Alifel rubbed his temples. “Of course, the coloration was similar enough, a remediate like himself would be careless enough to mistake it…there’s no point in retrieval now, he’s almost certainly contaminated it beyond repair as is. Get that filthy thing away from the rest of them and bring them back there after you make sure they’re as clean as they need to be. I’ll do the croc sample with the next batch.”

“Y-yes, sir. I’m sorry, I should’ve noticed…”

“Yes, you should have. But you were clearly unprepared for this intrusion, so I’m laying the blame on him this time. Impart on him that he is NOT to return here, or I may have to get testier with you.” If that wasn’t incentive for Colin to make sure Barry didn’t return, what else could be? But as he hastened to do as he was told, another thought occurred to him.

“Sir? What happens if he drinks that stuff?”

“I imagine he’ll feel mighty unpleasant, and if he’s lucky he won’t be violently ill,” replied Dr. Alifel dismissively. “And if he’s unlucky, perhaps you’ll be able to enjoy your newfound solitude.” The callous way that was said definitely didn’t sit well with Colin, but again, this seemed like a bad time to make a statement.

Barry was, as usual, completely oblivious to his mistake. All he was thinking about was his multi-mile run to keep himself in great shape for the next football season. The fact that his gatorade tasted weird barely registered to him, he figured it was just the different flavor he was trying out since they’d run out of his favorite one during his last trip to the store. Nothing he was going to get all worked up over, it wasn’t worth it.

His approach to most of life, really. Some envied his laid-back approach, others thought he was even dumber for it. He really didn’t care and really didn’t see what the fuss was about - he was him, that was all he could ever be, what was the big deal? He just didn’t see the point in caring too much about too much - he put his everything into his workouts and his performances on the field, and that was all he really needed. Sure, he wasn’t a brainiac, he at least was able to keep up grades enough for eligibility but he didn’t care about smarts…he didn’t mind those who did, they were just living their own lives. Lives he didn’t need to worry about, his own was the only one he was responsible for.

Would that he had realized what he was doing to it. He finished off the bottle of what he thought was his drink and popped into a convenience store to buy another, getting a distasteful look from the clerk for his sweaty appearance that he barely even registered, and continued his run back towards the apartment he shared with Colin, slugging down more gatorade that certainly tasted more like normal. He had no way of knowing that a foreign life-form had invaded his body, and was now replicating extensively and starting to alter its new environment to be more hospitable towards it, using information it had already been provided to start to make significant adjustments…

He still didn’t know that by the time he started to register that something was off. As he was nearing the apartment building, Barry was becoming aware of a serious discontent in his gut. He let out a groan as a pain and discomfort ground through it, putting an arm over it as he stopped his run and leaned against a building wall. “Huuughh…” He felt like he wanted to vomit, but at the same time there was no reflex pushing him to do so, leaving him to suffer whatever was in there. Had the gatorade actually been bad? He’d never heard of that happening before, at least not unless someone had left a bottle open for weeks or something…

A weird feeling started to rush through his body, making him fall to his knees. He started crawling back behind the building - his head spinning enough that he thought he was going to the front, in a hope that someone could find him and get help for him. In actuality he was ending up well out of sight, in the back alley that was rarely used…maybe to his benefit in a way, as what was actually happening would probably have made exposure far more dangerous. Not the Barry knew it, as he was fixated on the way his body was starting to feel like it was on fire, every inch of it raging with pain that he couldn’t possibly understand, utterly clueless as to what could have happened - surely gatorade couldn’t have THAT big an effect, right?

Surely not, if that was what he had imbibed. But the microscopic alien life-form currently working him over absolutely could. It had ‘read’ what this host’s biology was like, and found it inconsistent with the samples it had already been primed with - so, naturally, the best way to deal with that was to fix it. Billions of years of evolution had developed some truly astonishing feats of microbiology on Earth, and humans were no exception - but it couldn’t possibly have been prepared for something completely foreign to it, and had no response as it was overrun and corrupted, reformatted to suitability for its new guests. As they spread further and further, small-scale changes were giving way to larger ones, as the alien life and the corrupted cellular structures began to rework things the way they all thought it should be.

Barry was not cognizant of what was happening to him inside…he was not even truly cognizant of what was happening on the outside, on account of his head having gone loopier than the time he’d been tricked into dropping acid. His skin was starting to harden and darken, the structure of it slowly changing into something more scaly. His muscles, already relatively impressive, were getting bulkier and shifting around as his skeletal structure was being readjusted in shape and scale. His face felt extremely weird as the entirety of his skull was being reworked, something just above his ass was in raw agony as it was pushing out, his groin was screaming in agony as gross adjustments were being driven in…panic couldn’t even set in as his brain was overwhelmed completely with everything that was going on, beyond his comprehension.

No one was observing him…had they, they would have seen Barry slowly growing, more and more, straining his clothing to the breaking point. His shirt was being torn to shreds as the body containing it got far too big for it, a rough scaly hide being more and more exposed to the air. The shorts and boxers didn’t take much longer to surrender, as the slowly building thick and heavy tail tore the backs harshly, and the rest of the growth simply continued that destruction until they had pretty much fallen off. The sturdier athletic shoes held out longer than the rest, but eventually they too succumbed, breaking away as broad, clawed feet with slightly webbed toes were exposed, released from the exceedingly painful confinement. Less and less covering him until he was almost entirely exposed…

Not that he was in any condition to care. Barry was pretty much senseless still, unable to process everything going on. Unaware that his hands and feet had adjusted to thicker, slightly shorter digits with long claws, with flexible webbing between them that could extend or retract to a degree. Unaware that his entire surface was now a scaly, pebbly hide, with a pronounced spikiness down his back. Unaware that he was now sporting a large tail that looked like it could send a man flying with enough of a swing. Unaware that his head was taking on a much longer, V-shaped structure, with long fangs and dark eyes. Unaware that his brain itself was currently being reconfigured by the attack of the alien life-form, rewiring it to suitability for its new host’s physiology.

It was only as the pain and the burning faded away that sense began to dimly come back to Barry. He slowly became aware that he was collapsed on the ground, and that his face was far further out it front of him than it ever had been. From there, every new aspect of him was a quick discovery…he was still too much in a fog to feel much of anything over it, neither panic nor awe nor terror was having a chance to register, just numb awareness that he wasn’t what he used to be. What he WAS, he wasn’t entirely sure, either, but he had enough cognition through the haze to register that he looked like some sort of alligator or crocodile - except, one built on his old human frame. And even then, it felt like that wasn’t truly sinking in properly, like some part of him wasn’t accepting it yet.

The confusion wasn’t flagging as he managed to stand up unsteadily, trying to figure out how to adjust his balance with a new weight behind him. What few tatters of clothing remained in him were torn off, being useless for covering him anyway. A mild bit of disconcert registered as he didn’t see anything visible down between his legs, but that was a problem he had to think about for a different time…right now, the only thing he could truly focus on was that he needed to get back to his apartment. But he also had the feeling that he didn’t want to be seen…

———

9:00 PM. The time Colin figured that Barry would be back by if he wasn’t getting busy. Which meant that if he WAS, he probably had at least another hour.

Perfect for what he wanted to do, at least.

It had thankfully been an uneventful rest of the day after that unexpected intrusion. Sample monitoring and note-taking were the rest of what he’d had to do, including assisting with Dr. Alifel’s observations and taking dictation from him. He didn’t really know everything Dr. Alifel was talking about, but he was trying to learn, since not everyone got the chance to study something like this, even superficially. The professor was certainly excited every time he spoke about it, though…he must have been seeing things he liked.

Then it was back home, and grabbing his package from the mail room - ignoring the snoopy questions from the bored attendant, who seemed to think it was her business to know everything every resident was getting in the building. If they were half as dedicated to doing their jobs as trying to snoop, maybe there wouldn’t be complaints about missing or delayed messages or packages…thankfully, Colin had been able to get away without too many issues. From there, he was more than happy to just lounge for the rest of the day, and wait and see if Barry was going to be back for a frank conversation or if that would wait until morning. It seemed the latter option was what was happening, and Colin didn’t mind that - it was probably better to have the talk in the morning versus at night, because Barry’s head seemed to lose things overnight.

But that also meant that Colin could indulge in some of his own personal time. Technically, he could do so in his own room at any time, but unlike Barry, Colin felt incredibly awkward about doing that - especially because Barry could walk in at any time, since he already had a tendency to do so if Colin didn’t lock his door. Only when Barry was out, and going to be out for a while, was he comfortable indulging, ensuring no risk of weird questions or awkward conversations. Which he had no doubt there would be, if he was caught.

Adult toys were one thing, after all - adult toys modeled after fictional dragons and lizards were quite another.

It was only in the last year or two that Colin had discovered THAT particular crank-turner - just an accidental encounter with a draconic pin-up on a social media site, caused by just a simple typo, leading to a well of very unexpected and slightly awkward self-discovery. And what he’d discovered, in the end, was that anthro reptiles were fucking HOT. Naturally, he kept this an even fiercer secret than his homosexuality, but the desire was enough that he had actually worked up the nerve to indulge in some adult toys of that nature. He wasn’t exceptionally experienced with dildos, but someone who was capable of doing their own research could usually get by eventually, and he had played around with them a few times, though of course his opportunities were somewhat limited.

His most recent purchase, though, had been…some would call it ‘ambitious.’ It was another dildo, but a significantly larger one, from a specialty site where that was certainly considered a good thing. It was kind of a beast, almost a foot long in total - and that was a ‘medium’! - and of course had the kind of exotic shape that Colin found most appealing. He had no illusions that he’d be taking it all the way down right then, he definitely needed more practice and more experience, but he’d wanted to have a tangible goal to work towards, and this fit the bill, if not the ass. However, he wanted to just try one time, to see how far he had to go with it.

Which was why he had it stuck to the wall of his room and was currently naked, trying to back into it just a little bit. He wasn’t stupid - once it was too much, he was going to stop, but he HAD to at least give it one slight test. His teeth clenched as he felt the tip connect with his asshole, and he tried to relax as he pushed back, slowly, slowly…the heating/cooling lube giving a bizarre feel as he stretched open a little, the tapered end pushing in all right at first but getting wider, wider…too wide, it was starting to feel uncomfortable, and he bailed, pulling forward and letting it out of him. He’d maybe managed to get an inch in before it was too much, not even to the true girth of it…but, that was to be expected, he needed practice. Still, at least he had an idea what he was up against…

A thump made Colin jump. Was someone there? Did Barry come home? He jerked his head over to the clock - still only 9:20, it couldn’t have been him, he should have still been out! There was no way he was ready, he just had to hope that Barry wouldn’t barge in like he usually-

<WHAM> Colin yelped and fell over as his door was bashed open - luckily it had been cracked, because that probably would have taken it off the door frame, and as it was it might have been damaged from the force. But that was secondary to the more immediate problem - what had just nearly bashed his door down was a mammoth of a CREATURE. It looked like something straight out of those sites Colin had become familiar with, a mountain of muscle with a reptilian bent, looking like a crocodile man of some sort. It was rumbling, staggering a bit, looked to be confused…as was Colin, of course, he’d not expected something like this to just barge into his room, Barry was one thing, but who even WAS this?

And then came the words…slow and guttural, like they were struggling to come out. “Bro…why…are you naked?”

If Colin thought his shock was already at its maximum, he had just found a new peak. “BARRY?! What the…what the fuck happened?!”

“D-dunno…some…weird thing…” The words sounded somewhat distorted, perhaps to be expected for a creature whose mouth didn’t move like a human’s, but not so much that Colin couldn’t figure out what they were. “Musta…been that drink…maybe bad…”

“That…oh, no…” Of course, Colin was starting to put it together. Maybe he should have before, but then again, who could have expected THIS? “Barry, you…you grabbed one of the experiments by mistake. That…of course, it was the crocodile sample…but…what the hell? That stuff can do THIS?! We gotta call the professor, we’ve got to let him know what’s going on, try to figure out what we’re gonna do about this…eh?” While Colin seemed to be fixated on the problem, Barry’s attention seemed to be wandering - and his face reddened as that wandering landed on the dildo on the wall. “Ah! Barry, focus! We’ve got a problem here!”

“Bro…is that a dildo?” A goofy growling laugh escaped Barry’s maw. “Hah…guess that explains the lack of girls…”

If there was any doubt at all that this was Barry, his behavior pretty much dispelled it. This was the last thing Colin needed, a crisis with his roommate while he was completely out of his element…his roommate who was currently an eight-foot-tall hunk of alligator meat built like a very horny god had sculpted him lovingly, with thick arms, powerful legs, a sturdy trunk, muscular tail, dangerous claws and fangs that were viscerally terrifying and enticing, and a swampy, musky scent that was flooding the air around him right now…he tried to shake his head, Barry was already distracted, Colin being distracted would only make things worse. But it was hard to ignore the behemoth standing right in front of him, or what it was doing to him…

Barry took a step closer, looking Colin up and down. “Bro…are you horny right now?”

“Ack! N-no! Not horny!” Colin’s erection was betraying him, though…he hadn’t actually been hard when doing his test, it had only happened after this big croc creature that was Barry had entered. And he couldn’t will it to go away, even though he knew he should. Trying to think unsexy thoughts wasn’t working when the only thing he COULD think about was Barry filling his vision…and getting closer. “B-barry?!”

“Hrrr…you smell kinda sexy, bro.” Colin couldn’t do anything but let out a squeak at that. Did he really just HEAR that? “Look kinda sexy, too…”

“That…B-barry, h-hang on, you’re not…I know you’re not into guys!”

“Yeah…I didn’t think I was either…but…rrrr, maybe you turned me, bro…” Barry was looming over Colin now, the full intimidating nature of his size getting right up into the human’s face. “Mmph, something…ah, I feel…hrr, just…give me…raah!”

Colin wasn’t sure what was going on, when Barry’s crocodilian face tensed up and he seemed to be straining with something…he got a faceful of it, literally, as the flesh parted at Barry’s groin and a dick outright SHOT out of there, splattering Colin with droplets of warm fluid. A rumbling purr escaped Barry as he seemed to get a lot more comfortable with that out in the open…and Colin could understand why, when he was able to get a look at it. That thing was HUGE…it outclassed his new dildo, and not by a narrow margin! And it definitely had ‘exotic’ written all over it, with a bulbous end that seemed to flare out a bit, a narrowing for a few inches past and then a thickening out again, with little bumps over that thickest part. Like nothing Colin had ever seen, and he had seen some unusual designs for sure.

Barry growled down at him, pointing towards that behemoth of a staff. “What’re you waiting for, bro? Suck it.”

Colin couldn’t imagine what his face looked like now, trying to both pale and redden at the same time. Surely Barry couldn’t be serious? That thing was longer than his arm, there was no way he was getting it inside him. But he seemed to have lost his voice, the objections not coming out as he was faced with the prospect of that monster being used on him. The reality was, Barry had him cornered, he was drastically bigger than Colin, probably drastically faster too - Colin knew gators looked slow and lumbering but they had burst, and Barry had had a good bit of burst before - and if Barry wanted him to suck his dick, Colin essentially had no option, because Barry could very easily force him to do so at will, and there was nothing he could do about it. And that bit of knowledge was both frightening and disconcertingly arousing.

Hesitantly, he pushed himself forward and leaned into that thick staff, bringing a trembling hand up to it to tilt it down towards his mouth. It felt heavy, warm, wet, the swampy scent was even stronger here, a bit hard to handle but Colin pushed through it, knowing he’d get used to it. A lick at the tip got a tense growl from Barry, one that was tinged with a rumble of amorousness…Colin hoped he could keep him happy with just these actions, because getting that into his mouth was a non-starter, it would be like trying to cram his fist in there. Licking and slurping over that unevenly lumpy head was certainly getting Barry somewhere, though, as Colin could feel that cock twitching and pulsing…as he dragged his tongue over, a gush of precum pumped into his mouth, making him cough a bit and then swallow, the briny fluid leaving a strong aftertaste he couldn’t quite describe and a strange tingling sensation all the way from his mouth down his throat.

What the hell is even happening right now… Colin was still trying to process it all - essentially like if one of the fantasy creatures he’d lusted over had come to life and invaded his room without warning. And he was working over his cock like his life depended on it, while in the back of his head thinking that there was a nonzero chance that was literally true. But if he could keep Barry happy, maybe he’d been a quick trigger and a quick finish, and one of those guys who went down after round one, and Colin would have at least a bit of time to try to figure out what he should do from there…

Except, Barry didn’t seem content to leave it at that, as Colin felt a heavy hand on his head. “C’mon, bro…you can do better than that. I wanna feel it going DOWN…”

“Ba-mmph!” Colin didn’t get time to protest as a forceful pressure was applied to the back of his head, his mouth suddenly getting attacked by an insistent cock that was far too big for it. More pre was drooling into him, Colin was swallowing frantically so he didn’t get overloaded, hoping that Barry wouldn’t push it any more than this…it wasn’t possible, he couldn’t fit it in, he couldn’t possibly open enough for that, doing so would have to break something. But Barry was still pushing, and Colin’s eyes were watering as the force tried to push against his jaw, open it beyond what was truly possible. NOW he was actually panicking, if Barry didn’t relent something was going to give and Colin was sure it was going to be a bad result whatever it was…

He wasn’t ready for what actually happened, though…the tingling had become a straight-up buzzing throughout his oral cavity, and he was feeling weird sensations all throughout. It was hard to focus on them with the pressure trying to force that cock in…but suddenly he was aware of an odd stretching sensation, his jaw opening wider than it ever should have as that head tried to shove in. His eyes bugged out as he felt more and more give, until suddenly he felt it POP in, the push on his head making his mouth distort wide as he was suddenly plugged up with croc cock. And that was just the start, as Barry kept pushing, and Colin felt his neck start to warp open for it to…his arms flailed as he tried to pull back, but Barry had much more power, and inexplicably he breached Colin’s throat…and then RAMMED in deep.

The smack of Colin’s face against Barry’s scaly groin made the human freeze and stiffen. His eyes were rolled back in his head, mind in a fierce chaotic whirl as he was acutely aware that Barry had just HILTED him with that insane thing. It shouldn’t have been possible, even in the slightest…but even more impossible was the sinking realization that it wasn’t hurting. Something that big, he should have been in agony, should have been moments away from breaking and tearing, but while he wouldn’t call it comfortable, it was…tolerable. And even that felt like an absurd thing to think…

He barely had time to focus on that before Barry started to thrust. Dragging that leviathan out partway, then shoving it back in, slightly less forcefully than the first time, sparing Colin’s face a battering from that hard groin, letting out guttural growls and hisses that made the human shiver madly. Such wild sounds only added to the surrealness of the crocodilian facefuck…he was no longer fighting it, surrendering to Barry’s obvious overpowering strength, giving him what he wanted. He couldn’t believe that he was still sensible, still alive after this…

That was when a nasty thought hit him. Oh, fuck…oh, fuck…the alien stuff…that must’ve been part of what changed him…is it still in him? Is that what that tingling was? Fuck, did he just infect me?! Is it turning me right now too?!

Not the most pleasant thought to have when dealing with well over a foot of croc cock using his throat like a fleshlight. Colin couldn’t do anything about it, but he was starting to become aware of the tingling all through him now…he wasn’t sure what was going on, but he had a feeling that something was happening underneath, something that he most likely couldn’t undo even if he managed to get away from this in one piece. And all that he could do right now was making gagging and choking sounds as he was plugged over and over again by Barry’s immense piece, gushes of pre being forced down his gullet without his volition, adding to the fluid already in there that might have been tainting him…

Suddenly Barry grabbed Colin’s head with his other hand and he bucked in, HARD. Once, twice, three times, and then out came an echoing, hissing roar, and Colin felt a sudden surge of much thicker fluid get forced in, pouring into his stomach in great gushes that came, and came, and came with such fierceness that he wasn’t sure how he was going to keep it down once it stopped. Again, all he could do was clamp down, tighten that fraction more in a passage that was already overly tight…the tingle through his body was disconcerting, but at that moment his head being cloudy from lack of air was a more important issue. One that Barry, unsurprisingly, seemed to be ignorant of.

How Colin managed to remain conscious through it was beyond him…all he knew was that he was QUITE glad for Barry to finally drag that slab of cock out of his throat, pop it out of his mouth, and let him loose. He flopped back, panting hard, feeling quite full from all the seed packed in…somehow it wasn’t coming back out, which he was thankful for, because he rather disliked the idea of puking up gator cum. What little he’d gotten to taste was lingering on his tongue, that flavor impossible to describe in fullness, but certainly thick, heavy, salty, and tinged with that musky scent…so strong, yet not entirely terrible, if he was being honest. All he wanted to do was catch his breath, settle down, and then try to get his head back in order…

His wants were not the only ones in play, though, and Colin let out a tired and breathless yelp as he was jerked by the leg towards the gator, and then snatched up. He was lifted bodily and held against that rough hide, pinned by those powerful arms as Barry stood up with him. His heart skipped a beat as he felt his taint and balls still being rubbed by a slick and slimy erection - Barry, it seemed, was NOT as worn out as he was. “H-hang on, Barry, we just, ah…”

“Mrrr…not done yet…” That monster cock slid under Colin, drooling some fluids onto the floor - he was definitely still ready, still productive even. Whatever that transformation had done was certainly fueling some libido and virility, to put it lightly. “You’re so good, bro…you’re gonna help me with this, aren’t you?”

That question seemed to be academic - would Barry even stop if Colin said no? He seemed to be unusually aggressive, which would not have been a shock given the creature he’d taken the form of…and Colin couldn’t physically stop him in the slightest, especially like this, Colin’s arms weren’t even pinned but it didn’t matter, he couldn’t match Barry’s strength, he doubted hitting him would even register. If this was going to be happening anyway…and, despite everything, Colin almost felt like he WANTED it to happen. Even if he was probably going to be destroyed. “Ah…I…I’ll…help you, Barry…” Even saying it almost felt like it sent a shiver of arousal through him, like giving in to the beast was natural and right.

Slowly, almost agonizingly drawn-out, Barry dragged that cock along Colin, smearing his fluids all over the human’s balls and taint, making him tingle and shudder in unexpected pleasure. Then came the lift, as Colin was positioned above that thick-headed tool…it felt impossible, far too large, he hadn’t even been able to get a much narrower dildo more than an inch or so in. But Colin had no illusions that Barry would stop now…he essentially had to hope that he was going to be just as stretchy on this end as he had somehow been in the mouth and throat. He didn’t FEEL like he was stretchy there, though…but Barry was tensing up, he was almost certainly going to ram it in, and Colin felt a spike of panic. “Ah, Barry, wait, slow-”

Slow was not in Barry’s designs. A snarl erupted from the crocodilian as he PULLED Colin down hard as he drove up, his mountainous strength ensuring that he would not be denied. That slick shaft drove in, spreading Colin open wider than the human could ever have imagined; Colin’s eyes bugged out as he let out a silent scream at the impossible imposition, as his body was invaded by that gargantuan cock which surged in without hesitation. The smack of Colin’s rear on Barry’s scaly groin was loud, wet, and hard, far overboard and overwhelming, as the ridiculous intrusion completed its opening argument.

Colin’s mind righted itself as he hung limply in Barry’s rugged arms. Panting hard, head spinning, eyes unfocused, impaled on more cock than he ever imagined, in far more abrupt fashion than he ever could have been ready for. The pressure inside him was enormous, it felt like his body was struggling to accommodate that staff, trying to stretch in ways it wasn’t designed for. And…somehow, inconceivably, that was the worst of it. It didn’t hurt…in fact, he weirdly felt GOOD. Overwhelming, yes, but also good.

Barry wasn’t paying attention to his state, though…the croc’s impetuousness hadn’t abated in the slightest, and suddenly he jerked back and slammed in again, going far harder than he had in the first round. And Colin’s mind was once again caught off-guard and forced to scramble to catch up as his body was used as Barry’s plaything, speared into over and over with a tool that seemed like it was trying to break him rather than pleasure him. Which, for all Colin knew, was true…but the pleasure was breaking through nonetheless. The constant pressure on his prostate, utterly impossible to avoid with such a massive girth, was sending thrills through Colin’s reviving erection, and the tingle in his body was starting to feel quite good as well, like his body was being molded into a sleeve for that monster dong. Thin, wavering cries started to escape him, only to be stuffed by a scaly hand over his mouth, as Barry tried to ensure as little would draw attention to them as possible, perhaps recognizing under the haze that secrecy was still important.

Colin didn’t care - as far as he was concerned, Barry could do whatever he wanted to him. In the delirium of everything, he was slowly becoming convinced that everything that was happening was everything he WANTED to happen…even the ruthless roughness, the borderline forced imposition, the conquering breaking, all of it was starting to meld into him like it was everything he’d been dreaming of. In the back of his head, he was realizing that this might be something that was being done to him, part of whatever was being altered inside him, but did it matter? It was happening, and there wasn’t any choice but to accept it, nor any reason not to.

Slowly, he was getting more active. Squirming in Barry’s arms, moaning ruthlessly into that clawed hand, squeezing down onto that croc cock with what little ability he had to clench - not much, given the insane stretch that had his muscles overly warped already - and reveling in the feeling of that thick precum pumping into him, making things nice and sloppy. His ass was soaking wet, dripping into the floor as each thrust forced some fluid out and around, while also forcing some deeper inside, to join the load already settled in his guts. His arms were clenching onto Barry’s, his legs were occasionally spasming, banging into Barry’s legs without having any real impact…he was as thoroughly dominated as someone could possibly be, utterly incapable of resistance to this titan, and it felt FANTASTIC.

How long they were going at it, Colin didn’t even know. At some point he found himself cumming once again, squirting a feeble dollop from his protesting balls that barely registered among the mess of croc fluids underneath him, the pleasure spiking and making him squirm a bit more vigorously. He could feel Barry’s cock throbbing, pulsing, stretching him even further, as it prepared for an explosive finish - and Colin wanted every drop, wanted it to fill him, claim him, flood him so full he might look like he was carrying Barry’s spawn. And he was trying desperately to squeeze down on it, giving him more and more until…

Colin had just enough wherewithal to reach up and clamp his hands around Barry’s long jaws, keeping them snapped shut nice and tight and attenuating the roar that came out of him as he slammed in and started firing round after round of thick crocodilian jizz into the human’s body. Each shot felt incredibly heavy, and it kept pushing in deeper and deeper, only a trickle of it seeping out, denied freer exodus by the sheer mass of dick plugging Colin up. The already heavy pressure redoubled, Colin swore he was in danger of bursting from the sheer amount of fluid packing into him…even though, from the outside, the swell was only modest, feeling much more immense than it looked. But it kept building, more and more, an unbelievable level of virility on display as Barry emptied every drop he could into Colin, and Colin merely squeezed, trying to milk him as much as possible.

Finally, it felt like the pressure wasn’t building anymore…not that it was being relieved, Barry wasn’t making any move to pull out of Colin, content to leave himself inside his human sleeve. Colin let go of his jaws, falling totally slack as exhaustion overtook him, no chance of recovering any time soon. Thankfully, Barry finally seemed to be sated…at least, he wasn’t trying to pick back up with the fucking. He was starting to move, though, making Colin moan incoherently as he stumbled over and flopped onto Colin’s bed, jarring the human a bit as he was tossed around and felt that mass of liquid slosh around inside him. He had no idea what was going to happen to it…maybe it was going to make an almighty mess once Barry softened up. But that was a problem for tomorrow’s Colin, whoever it might end up being.

“Hrrr…heh…bro…” A quiet, tired growl from Barry reached Colin’s ears. “That stuff I drank…heh…I guess it was GAYTORade…”

Colin’s groan was only halfway because of the strain in his body this time. Of course Barry had to be Barry… “Crocodile, Barry…not gator…” was all that he could muster as he waited for weariness to take him to slumber.

———

“Are you sure this is a good idea, Col?”

“I’m not sure a ‘good idea’ exists anymore, but this is the best thought I can think of.” Colin was pacing around a bit in his room, rubbing his head as he tried to keep himself calm. Barry was sitting on his bed, still a massive crocodile person, and looking uncharacteristically anxious. It seemed that clarity had finally sunken in properly for him, his head now somewhat more right than in the aftermath of the transformation. Something Colin was quite thankful for - Barry as he normally was might have gone out obliviously and gotten a SWAT team called on him.

And Colin was equally concerned about himself…having woken up still human, he was reasonably certain he wasn’t going to be following in Barry’s scaly footsteps in that regard. That part of the transformation appeared not to be transmitted, at least not that way. But something for sure HAD happened to him…particularly because Barry’s claws had been digging into him when he woke up, but not piercing him. Whatever Barry’s fluids had done to him seemed to have at least made him less vulnerable - probably the reason why he wasn’t outright killed by that furious fucking the previous night. And it didn’t seem to be transient, at least as far as Colin could tell - he’d had a good way to test, and had been able to confirm that both mouth and ass could take his dildo, unlubed, without hardly a hitch.

Though, as it turned out, he probably was going to be busier with Barry’s tool than that one. The croc had joined him in the shower, and it hadn’t taken long for him to start getting hot and heavy again - and the moment he had, Colin had fallen in, ceding immediately to Barry’s desires and loving the ruthless rutting all over again. At least he’d gotten to empty himself out in a place that didn’t need more cleaning this time, but he was starting to get the picture about their new dynamic…Barry probably had some kind of signal his body was naturally attuned to, making him more than willing to give himself up if the croc was interested. Really, it was hard to be too disappointed by that…Barry had become the incarnation of his fantasies, and even if it made no realistic sense, he could take everything that the croc had to give, so it was hard to find too much wrong with that.

But…reality had more issues than that. And that was why Colin and Barry were both currently feeling nervousness more than anything. Colin had called Dr. Alifel that morning, leaving him a message to call them through a computer messaging app when he was available. It was dicey, to be sure, but Colin couldn’t think of any other way of trying to deal with this situation - no one else he knew would react well to Barry. And Dr. Alifel probably wouldn’t, either, but at least maybe he’d have incentive to try to help, knowing that his research was potentially at risk.

The telltale tone of a call coming through on the computer made them both jump - even knowing it was supposed to come, it was too sudden. Shakily, Colin stumbled over and answered it. “Dr. Alifel?”

“Colin? What’s going on? You know you’re not supposed to contact me on weekends.” Terse as usual…Colin doubted that would last long.

“Sorry, sir, but it’s absolutely urgent. It’s about Barry.”

“Oh? What happened? How ill is he?”

“He’s…well, sir, that’s why I wanted you to call like this. Uh…let me…turn on the camera.” Taking a deep breath, Colin did so…it took a few seconds for the signal to connect on the other end, but when it did, the reaction was immediate.

“JESUS OF NAZARETH! Is that him?!”

“Ah…h-hi, doc…” Barry replied nervously, giving a hesitant wave.

Colin swallowed, but continued. “Yeah, that’s him. He…apparently changed not long after drinking that stuff yesterday. And…well, there was other stuff, but…”

Silence at the other end, and Colin was feeling the prickle of anxiousness. If Dr. Alifel was reacting poorly, then that boded very ill for their hopes of getting out of this even somewhat okay…his mind was running through all sorts of bad scenarios for what might happen to them if they had to try to make a break for it. But then the professor’s voice came through, and Colin found himself getting more anxious for an unexpected reason…that Dr. Alifel was reacting TOO well.

“Well, well…I guess the meathead was good for something after all. What a monumental breakthrough! I will need to know absolutely everything. Both of you! You’ll come to my lab tonight, no questions asked. I assume the cover of darkness will be necessary, but once I’ve ascertained a few things I should be able to arrange some kind of transportation and lodging as needed. We’re going to make the most sensational proposal those agencies have EVER seen! Arrive as soon as you possibly can, I’ll not want to waste a second!”

The call clicked off, before either of them could say a word either in affirmation or protest. Colin and Barry exchanged an uncertain look…maybe they were in even more over their heads than they’d thought. It was potentially someone on their side, though, so they really had no good option apart from following it wherever it led, and hope that the end was a good one…
