Pulling back from his desk and wiping the sweat from his brow, Joel took off his gloves, standing up for the first time in hours. Going to wash his hands, he took a long swig from his water bottle, gasping softly as he did so. He had been at it for hours in the lab and had many hours left to go with how much work he needed to complete. At least he had Brent with him, though they were the only people his company could spare for the moment. It didn’t make the reality of his work week any less troublesome, however, and he was looking forward to a much-needed rest when it was over.
The constant grunts from the ape in the room with them broke him from his reverie. That was the other annoying facet of working this long in the lab. Joel hated the company’s poor treatment of the beast, being kept in close quarters, and having his blood taken several times a day. But there was no other place to store a live specimen and the necessity of having this one close by made them resort to less humane means. The animal was currently upset and frantic, though there was little they could do to ease his irritation. There was every chance he wouldn’t be able to return to his captivity, depending on the results of their tests. The disease he was thought to have contracted was a mystery, and it was their job to cultivate, study, and test common means of vaccination and control. If things went well, the disease would prove simple enough to be treated and contained. But if not…then things would become far murkier. There was a low chance of that, of course, but every precaution had to be taken.
The ape, save for its irritated and distressed state of captivity, seemed no worse for wear by the illness, as though the virus in his blood had stagnated. The real concern was how easily transmissible it was, not only to other apes but to humans as well. Such zoonotic vectors had been researched more thoroughly in recent years, especially in those species more closely related to humans. It was tedious, long work, but Joel and Brent were competent, and it was hoped their trials would show favorable results sooner rather than later.
“Time for a fresh sample,” Brent called out, and Joel moved to don his PPE, his turn to take the blood sample. Naturally, the ape had been less than cooperative in donating his blood, and this time was no exception to the point that Joel needed help getting his arm out through the gloves in the plexiglass cage. There was a second pair of gloves for Brent’s use, and the two of them worked to take the ape’s arms, lulling him over with a treat as they did so. In fact, the ape soon calmed enough that they were able to take his arm, and with a singular prick, their sample was drawn. And then…
With a mighty howl, the ape ripped his arm back and with it, the needle. Shocked by the sudden outburst, Brent was pushed back, the needle tip piercing the gloves and his skin as he cried out in pain. The ape, too, was cut and bleeding, though his pain was hardly the priority when there was every chance Brent had been infected himself. Joel acted quickly, grabbing the first aid kit as Brent flushed out the wound. It was unlikely to stem the chance of infection, but in the immediate present, there was little else they could do.
Given the classified nature of their research, calling a doctor was out of the question. Still, the wound was relatively shallow, and Joel was able to help quickly bandage it. At the moment, hadn’t noticed the water-diluted blood splashing on his arm, over a forgotten cut that had all but healed over. That was hardly the biggest concern, of course. Making sure that Brent’s wound was bound, Joel went to take a blood sample as both waited nervously for the results. There was no guarantee the virus would show up this quickly, but they had to try nonetheless. It would be disastrous if Brent was infected, the implications on humans unknown though likely not appealing. Thankfully, the cross-contamination was minimal, and there was every chance that Brent would come out unscathed…
“Shit…” Joel muttered, and Brent knew he was screwed. With their research in such an early stage, there was no way to understand the effects of the virus on humans, let alone guarantee the ability to concoct a cure.
Feeling anxious, Brent sat down hard on his stool, mind racing with possibilities. He was sweating, of course, from the exertion as well as the fear over what might happen. Yet, the longer he sat there, the more he began to attribute the sensations to an onset of illness. Overheating now, he went to take off his lab coat, protocol be damned. Besides, he was already infected with something they had no cure for or even fully understood the repercussions of. That was what they were trying to figure out, damnit! If only they’d had a chance to finish, then…
The heat running through his body seemed to be worsening rapidly, and Brent was left shivering, wanting to remove his shirt as well. Sticky sweat clung to his body, creating a potent stink, one he was unaccustomed to. Yet, rather than disgust him, the musky aroma seemed to steadily have another effect, one that caused a rather unexpected stirring in his loins. Surely, he couldn’t be getting a boner, especially with no discernible source. But the onslaught of his erection was soon insistent, and Brent started rubbing his member through his pants, not caring where he was or who was watching.
Lost in his desperation to determine what might happen to his friend, Joel was hardly aware he was starting to sweat as well. The intense heat made him need to stop to wipe the sweat from his eyes. With the lab set at a comfortable temperature, Joel had trouble placing what might be bothering him. It seemed unlikely he would be infected as well, having not come into contact with the ape’s saliva or blood. Right? Yet, he, too, was compelled to take his coat off, a haze of sweat stinging his nose though smelling somewhat pleasant.
Lust quickly rising, Brent could hardly advert his gaze from his lab mate, as though Joel was a further source of the pungent yet alluring aroma. The ache in his member was getting insistent, and without thinking, Brent pulled his pants down, cock bobbing up and down and leaking its arousal. Before he realized what he was doing, Brent stood up, reaching for his lab mate. Grabbing his shoulders, Brent turned him around and gazed into his shifting features. Seeing Joel’s eyes glazing over as well, Brent moved in for a smoldering kiss, needing the contact more than anything he could fathom despite never having felt an attraction to his buddy. Still, Brent fell into the moment as he made out with his friend with vigor, the rest of the world fading around him.
Joel hardly had the awareness to try to resist the advance, though the moment Brent started to kiss him, Joel was enthralled. He didn’t even try to struggle against Brent’s strong hands, rather getting into it, kissing him back and panting his lust. His own member soon came to a painful erection, though Brent’s hands were there to help, lowering to help pull it out, their two shafts bobbing together. Soon, Brent was rubbing their cocks together, both men moaning into each other’s lips as though the horniest men alive. Any shame or embarrassment over the act was soon removed with the pleasure of the others’ touch, and Joel found himself eager to see the encounter through to its conclusion.
Frotting their cocks together, Brent was a little shocked when the sensation of the twin pricks in his hand seemed to enlarge somewhat. To Brent’s delight, their sensitivity seemed to increase ten-fold, making him grunt in a voice that did not seem quite like his own. He continued to rub them eagerly, wanting to see how large they might become as a result of his actions. At the moment, it felt more right than anything he recalled in recent memory! Part of him was vaguely concerned the virus was the cause of these changes, but that still left him little ability to resist when everything simply felt so good.
Lost in their lip lock with closed eyes, Joel was hardly aware of the alterations to their facial features, save for an odd tingling and an irritating itch of hair growth. A seeking tongue traced over teeth that were sharper, Brent’s canines starting to lengthen somewhat. Joel thought to run his tongue over his own, finding the same changes and feeling a little alarmed. Though with the intensity of their make-out session, Joel couldn’t tear himself away, regardless of what was causing the alterations. Still, opening his eyes, Joel was privy to the sight of Brent’s brows furrowing, the skin expanding as though akin to a prosthetic being attached in real-time. A warmth over his face led credence to the fact his own forehead was shifting, and a panic settled into his mind, not wanting to lose himself to whatever physical changes were settling over their forms.
Yet, as the stench of their musk burned into his nose, any ability to resist was quickly wiped from his mind. Whatever the virus had done to him, it seemed to limit cognitive thought, lust at the forefront with no specific care about the outlet. While never harboring such thoughts about his labmate, Joel couldn’t imagine a sexier sight. The intense musk of their sweat and body odor sent a surge through his loins and made his blood pump faster than ever before. Even thoughts of returning to the microscope and searching for a way to reverse or limit the virus were whited out under the ever-present need to get off and cum. At the moment, it was impossible to place why giving in to their urges was a bad thing at all!
A brief surge in his mind had him struggling against primal instinct, something Brent seemed to be having a more difficult time with. His eyes were fluttering shut, as though fighting a losing battle against his devolving psyche. Joel, too, was left to grasp his head, primal inclinations flooding his thoughts and allowing his logic and reason to be washed away. Having always prided himself on his intellect, such was a terrifying prospect. Though as he grunted in a more bestial baritone than he was used to, Joel felt it frighteningly easy for him to lose it all. His struggle was for naught with the temptations of the flesh so close at hand.
In the end, the two were compelled to take off their clothes, not caring how shredded they became in the process. It was only a brief interruption to their fun as Brent continued to stroke their cocks together, the tension growing past the point of no return. With their arousal over their pungent musk and their changing bodies, there was little either man could do to resist as they cried out with a bestial intonation. Any hesitation was forgotten with the cascading waves of pleasure pulsing through their penises, twin ropes of rank seed coating the hairy skin of their groins. Both men grunted their release, panting and huffing in the heady musk that burned into their beings and provided a sense of satisfaction that their years of work had never known.
Even after such a powerful release, neither man felt they were fully finished. Their cocks quickly came to arousal once more, bobbing up and down with need. The ache was such that Brent was willing to get down, reaching out and exposing his anus for Joel’s inspection. Against his better inclinations, Joel found wanted to fuck this man, changing as he was into some sort of bestial devolution. The scents of sex wafting off his body were enough that he needed a closer whiff, and Joel did so, breathing in his friend’s stink and growing further erect as he did so.
Curiously, Joel reached out with his tongue, not sure where he had gotten the idea but unable to remove it without acting. Licking the puckered skin, a hoot and shiver from his friend was all Joel needed to know that Brent was into it. Joel eagerly reached out to rub his tongue against his friend’s rectum, teasing the edge and coating it in a layer of saliva. The texture of the man’s pucker was fascinating, and Joel worked to explore it in full, even inserting his tongue into his friend’s flesh. It was never something he would have imagined with any other partner before now, but in his moment of lust, there was no hesitation in his actions. The hoots of approval from Brent’s devolved lips were all the motivation he needed to continue his oral exploration.
Yet, Brent’s pleasure left Joel feeling curious, and he eventually pulled back, parting his ass cheeks in the hope that Brent would return the favor. Though obviously annoyed, Brent soon got up, the musky scents of sweat and cum enough to entice him forward. He, too, reached out with a curious tongue to tease his friend’s tender flesh. Joel moaned hotly, small tremors of pleasure burning through to his proaste and teasing his cock from within. The temptation was intense, though Joel was not inclined to touch himself, not yet. He wanted to prolong their foreplay, revealing his new sexuality and loving every sensation his virility had to grant him.
Of course, it did little to stem their lust, both men clearly desiring to fuck each other and seeking the final release they so desperately craved. It was harder to rationalize over their lust-clouded minds, almost like they had stupified little, bestial inclinations overriding human reason. Both felt a little aggressive toward each other, Joel turning around and smacking his friend before hooting his desire to fuck. In the moment of animalistic desire, he couldn’t imagine wanting anything more than to breed his pucker, even willing to take what he wanted by force.
It was impossible to feel regret as Joel shoved his friend aggressively to the ground. The sight of hair growth spreading over his body was powerfully erotic, making him into a beast worthy of Joel’s cock. Rather than resist, Brent was eager to expose his pucker, anus open and ready for him Without hesitation, Joel forced his cock in, grunting from the effort though finding it easy with the added muscle in his legs. The itching over his body was intense, and part of him wanted to scratch, though the heaviness in his testicles took precedence. He humped away with vigor, wanting to reach the end and blow his load.
It was impossible to focus beyond carnal pleasures as his body continued to expand, Joel thankful he had rid himself of his clothing. Wait, had he ever worn it at all? Such reflection was confusing, more reasonable for his stupified mind to hump away any errant thoughts. Hooting through rubbery lips, Joel felt his cock spasming and shooting a load into his mate’s asshole, the other ape-man elated as he began to orgasm as well. The room stank of their male musk, though for the moment, their cocks were satisfied and they could finally focus on the other facets their devolving minds dictated.
Pulling out after their romp, Joel found that as his forehead sloped, errant human thoughts were fleeting at best. He felt aggressive, energetic, and happy to put the smaller ape in his place by fucking him. The other creature hooted his irritation, though a heavy grunt in return made the other creature cower in submission. He had power over the other man, who had been…what, exactly? Did he have a name? Surely, it wasn’t important now!
A tightening in his shoes soon took precedence, and Joel reached down to rip them off, hooting his annoyance. The rank stench of his feet wafted into his nose, and he felt himself coming to a mild erection despite having already cum twice. It was not simply lust that drew his attention, but rather the fascinating sensation of his feet expanding, the toes curling in on each other as they widened against the floor. He had no idea why such was happening, having always had massive, lovely feet, right? It mattered little in the end as he was granted them, and Joel hooted his delight, flexing his toes as the tendons and joints popped and expanded. With his large toe rotating backward as it was, Joel reflected on what wonders it could do for him. With its increased flexibility, he would likely be able to jerk himself off!
Yet, there were other more pressing needs, like the hunger in their bellies that came from multiple orgasms. With that, the two of them tore the lab apart, throwing beakers and tubes and anything they could find to try and appease their appetite for destruction. It was joyous to trash their equipment, hooting their delight as the various pieces shattered. A fleeting thought made Joel wonder what he had used them for before, though the joy from watching things fly across the room and shatter was far too great to care further. It became a game of sorts, both changing men tossing things with their hands and feet in an effort to make the most noise.
A strong need in their bladders suddenly come to light, and Joel felt no hesitation about whipping out his flaccid dick. Urinating where he stood, a stream of pungent piss sprayed like a hose as he relieved himself. Seeing his discarded clothes close by, Joel felt it funny to aim his stream in that direction, urine splattering all over the torn clothing. Seeing his friend doing the same, Brent moved over to piss in an arch as well, hooting as he tried to make his stream larger. The two of them turned it into a game of sorts, emptying their bladders while staining their former humanity with contempt.
Eventually, bladders emptied, their hunger became their focus, and the two of them sniffed the lab with intensity. There had to be food in the lab and the two changing men were eager to find it. Behind a fridge door, perhaps, though Joel found himself unable to work the latch, as though his fingers had become too thick. Hooting as rage took over him, Joel flipped the fridge over, the door opening and food spilling out, fruits and treats the likes of which he could tell had been fed to the other ape in the room. Eagerly, he started feeding, biting, chewing, and throwing leftovers away as his friend came to do the same, taking the leftovers as soon as Joel was finished.
Yet, the moment his belly was full, a foreign sense of understanding came over him, and Joel shivered with fear, looking over his body. He was still itching, still sore all over as though his muscles were burning under the skin. His strength, while already having increased, was continuing to rise, and while a more bestial part of him languished such a prospect, the logical part of him was slowly able to take hold. Brent, whose name he now came to remember, looked around confused as well, as though just now coming to terms with what he had done. They were still changing, bodies still warping. If they didn’t stop it soon, there would be every chance they would completely fall into bestial inclinations, their intellect forever lost.
As quickly as he could, Joel made it over to one of the microscopes, thankful the one he’d used to observe the sample was untouched by their rampage. There was no answer under the screen, and his frustrations nearly let the beast back in, perhaps as a permanent part of his being this time. Yet, the more he stared at it, the more Joel started to realize the differences in the cell structure between their blood and that of the ape. Where the viral cells within their own bodies were multiplying out of control, within their subject, they were largely dormant. It seemed as though human cells were a catalyst for rapid infection. It was a long shot, but perhaps a fresh infusion of ape blood could…
The ape was relaxed in his cage now, and Joel’s primate musk was far more calming than his former human scent. While his changed fingers remained somewhat unruly, he was still easily able to draw enough blood for what he hoped would be the cure. There was no way to know, of course, not without further testing. But given the effects within the ape’s blood, counteracting the viral agent with an infusion of more blood was the only logical thing he could conceive of in his moment of desperation. Brent came over to him, hooting as though trying to speak but unable with his current vocal cords. Still, he was cognizant enough to hold his arm out, wanting to be the first to be injected directly.
Joel did so, arms trembling but still able to insert the needle. Brent grunted a little from discomfort, though pulled back to allow Joel to do the same. His eyes carried a glazed-over look, as though he was trying to fight against the mental influences and failing. Joel knew he had only moments to go before he would be unable to inject himself, and had to brace himself to make sure he did it properly. His trembling fingers struggled with the effort, but with some focus, the lancet pierced his skin and veins. With that, he was able to inject the foreign blood directly into him, hoping to all hope the dormant form of the virus would supersede the infection that was changing them.
Not sure what else to do, Joel collapsed, still feeling the itching of hair prickling his skin. Yet, the more he rubbed at the hair, the more sparse it seemed to become, as though it was receding into his skin rather than thickening. Was his cure working? Sore all over, Joel could not bring himself to stand up and take a sample, though at least the inklings of instinct were not as all-consuming as they had been. He was left to sit there, watching as the black hairs covering him continued to retreat. Soon, only bare skin remained as his skull ached and his feet started to reduce as well. It was working!
It was sometime later when Joel awoke, standing on unsteady legs as he looked around the destruction they’d created. Seeing the human form of his labmate coming to as well, Joel reached down, giving him a hand up as the two of them took in the wreckage together. The stink of cum and piss was strong in the lab, and the two quickly averted their eyes, not wanting to admit to each other what they had done. Still, even as the remaining changes retreated, Joel would not be satisfied until he took a blood sample from each. It was all he could to rush the slide under the microscope and see if any active remnants of the virus remained in the samples. To his relief, the results were more than he could have hoped for. It appeared at first glance that no trace of the virus remained in their blood, not even the dormant form that was observable in their lab specimen. They were cured!
It took them some time to clean up the lab, relieved at avoiding the deplorable fate of becoming dim-witted ape creatures, perhaps for the rest of their lives. Idly, the two discussed the things they would do that weekend, burgers and beer and movies, desiring with a renewed vigor for human, intellectual pursuits. Above all, they wished the memories of bestial inclinations to fade from their minds. Of course, as an added bonus, their research had reached a breakthrough, and they needed to bring forth to their donors what had happened. It was embarrassing beyond belief, but the implications of what their experience meant for their research going forward were innumerable. They had been studying a far different viral agent than they had first assumed and one that was potentially more lucrative, as well!
It was late by the time they got out of the lab, looking up at the sky and thankful it was summer, still light out. Both men were ragged, of course, though glad they had a change of clean clothing in their lockers. But it was of little matter, given their elation over what they had studied about the virus and having narrowly avoided its worst consequences. Certainly, becoming mindless, horny beasts was far from ideal, but the possibility it carried to alter the genetic structure of humans on an unprecedented level was far too tempting a prospect for potential investors. Even if they were not taken on as the primary researchers for future endeavors, the funding to purchase their research results would be such that they would never have to work again!
Grin on his face, Joel turned his head toward the sky, greeting the rising moon. It was rather beautiful, and as a man who kept his nose to the grind, he had not often taken the time to appreciate it. Massive in the sky as it was, its splendor seemed to draw more of his attention than he had anticipated. Yet, even with his thoughts lost as they were, Joel couldn’t think of a reason to look away. The moon was more alluring than even thoughts of what he would do with their research going forward. Its beauty seemed to awaken a need in him, something he wasn’t aware was familiar from his experience this afternoon.
A flush of arousal played over his loins, and Joel looked down to see the outline of a cock that did not match the one he’d possessed even earlier. A part of him was instantly panicked thinking that the change was coming once more, perhaps this time with even more ape DNA to work with that his blood had integrated. Reflexively, he knew he needed to get back into the lab, to take a blood sample and see what had become of the virus in their systems. Yet, it was too far away, and the ache in his loins was such that he couldn’t help but start to rub at it, moaning deeply as he had in the lab. Brent was inclined to do the same, getting down on his knees and massaging the bulge through his pants. Their erections were clearly larger, and becoming more so as the moments passed. The sheer amount of blood required to fuel such cocks was enough to make them dizzy!
It was not only their cocks to change as the tension in their testicles grew past the point of comfort. Swelling further than they had from the previous changes, their underwear was soon to part, and both men had no choice but to pull out their cocks. Both sets of tackle looked mostly human, though with darkening foreskins, it was clear they were shifting toward something bestial. Flopping in front of them, their cocks emitted a pungent male stink that further clouded the men’s minds, seeing no reason for them not to start stroking them right there. Bestial need was once more at the forefront of their beings, so strong that human reasoning was brushed away without a moment’s resistance.
“Broooooent! What’s happooooooning toooooo ooookkk! OOOkkkkk!” Joel tried to call out, but the moment he did so, Brent started to giggle, hooting his own reply as well. As panicked as he was by the changes, Joel couldn’t help but find the situation funny, a sign that his mind was soon to go as well. Yet, at the moment, there was little he could do to muster any concerns, enjoying the urges coming over them and the sheer bestial joy they seemed to grant.
Moving toward his still-human lips, Brent began to kiss him, and Joel moved into it, closing his eyes and submerging himself in the heady scent of their combined musk. Reaching down with seeking fingers, Joel was quick to find the massive, flopping cock of his lover, rubbing it against his own and grunting his approval. Even a repeat of their previous fun did not raise any alarm bells as the two of them reveled in their pleasure. It simply felt too right at the moment that even the threat to their intellect was not a sufficient deterrent!
With the weight in their balls and the promise of oncoming orgasm, neither man was inclined to hold back their lust. Ignoring the tingling over their faces, the two of them fell into release, spraying cum all over their hands and chests and adding to the potent musk. As much as it served to cloud their judgment, Joel was startled to awareness by the sight of Brent’s jaw distending, lips turning puffier and rubbery as they peeled back. Brent seemed to take joy in playing with his new flexibility, though with their erections coming back to bear, he knew they didn’t have much time before they were overwhelmed by instincts. Taking his hand before Brent could be tempted to jerk off once more, he moved them both back toward the lab. In their cloud of musk, it was becoming increasingly harder to think about why such was so urgent, but Joel was determined, even if his efforts would likely be in vain.
The now familiar soreness continued to play over their muscles, swelling against their clothing and pulling it tightly against them. It was enough to make them wish to stop and take them off, though Joel knew there was no time. Even more frustrating was the itching of hair growth like ants crawling over their skin. It spread around their treasure trails and bellies, creeping across their upper arms and legs, and even thickening over their groins below their semi-erect penises. The sound of tearing made Joel’s ears twitch, something he was sure he wasn’t able to normally do but finding it hard to worry about with everything else he stood to lose.
Feeling the alterations to his face was bad enough, but Joel made the mistake of looking at Brent’s face, a mirror into his own. It was akin to a horror show, watching his friend’s brow shift, his skull compressing as his nose bulged out slightly. It was the rubbery muzzle he now possessed that really gave Joel pause, lips pliable and jaw expanding to make room for larger teeth. The ache of his own muzzle took precedence as he gazed down to see it protruding in his field of vision. Any attempts to cry out were met with a series of ooks, something that his labmate was eager to imitate as though nothing was wrong.
Eventually, the ache within his muscles grew so much that Joel had to stop, panting as Brent put his arm around him. The scent of their heavy musk, more intense with wider nostrils and sweat from their exertion burned into their minds and clouded their thoughts. Brent seemed to have already given in, pulling his cock out of his pants with some effect. The outline of his testicles was firm in his pants, and Joel found himself more interested in getting down to sniff them than he was in trying to find a cure. A cure for…what? The moment the words passed through his head, they confused him, Joel teetering on the edge of a thought he couldn’t quite grasp.
The sound of ripping drew his attention back to the present as Brent’s expanding pecs and shoulders started to tear at the back of his shirt. The sleeves of his labcoat were forfeit, muscles looking powerfully out of proportion with the rest of his body. Hooting his irritation, Brent went to tear at them, aiding them along as a whiff of sweat and musk burned into Joel’s mind. Without thinking, he pulled out his own cock, stroking it a little before the tension of muscle against his clothing took priority. He, too, was eager to rub his muscles into place as they swelled under the skin. His upper arms were massive, out of place with his human body though he was steadily swelling all over in an effort to keep up. His shoulders, too, bulked up rather rapidly, leaving his flexibility in flux for a few moments. Eventually, his chest expanded to more appropriate proportions, and he was eager to play with his flattened pecs, teasing his nipples through his shirt as he hooted his own pleasure.
Lost in rubbing their new muscles, the ache within their shoes went unnoticed, feet swelling rapidly against their confines. It was happening too fast to remove them this time, feet already preparing to split the material. Still, as a part of him recounted how much he’d enjoyed the former mobility in his ape-like toes, Joel flexed them eagerly, feeling them stretching the material from within. It became a game of sorts, trying to push at the stitching as his toes enlarged and their flexibility grew. And it took little time for his twitching toes to work their way out, shoes rendered apart eagerly to allow his feet to breathe.
Kicking away their torn remnants, Brent and Joel gazed down at what became of their feet with eagerness. They were flat, massive, larger even than Joel recalled them becoming before, though he hardly had the brain power for such reflection. Still, as the toes spaced out and his large toe’s joints popped into place to allow a similar articulation to his thumbs, Joel began to play with them as though a child discovering a new ability. Even better was when Brent’s own ape foot moved to touch his own, Joel moaning as the enhanced sensitivity of his feet became aware to him. It was pleasant to feel their toes intertwining, even more as Joel reached down to stroke the other ape’s cock without any further through. Brent was quick to reciprocate, each ape hooting and stroking off with fervor as their feet played with each other. It was easy to forget they were in the midst of a detrimental change, every sensation powerfully visceral and allowing them to revel in their virile bodies.
Their heady male stink only rose the more the two of them jerked each other off, hooting and grunting their pleasure. Their shared masturbation seemed to accelerate the changes, chests pulling at their shirts as they tightened over their backs. Forests of fur erupted over their backs and sides, much of their chest bare as the skin turned thick and leathery, accenting their muscles well. The swelling within their upper bodies grew so much that a simple flex was all it took for their meddlesome clothes to burst, exposing black fur and more male stink. The cloudy miasma of male essence made it impossible to think clearly, both beasts hooting their pleasures as one, then the other went over the edge into orgasmic release. Geysers of cum blew from their testicles, coating their hands and groins and leaving them huffing and panting. Yet, with the sheer vitality the changes granted them, both found it hard to find fault in them, even as the release moved to calm their minds.
Brent seemed to furrow his brow just slightly, confused as though something was amiss. It was Joel who was able to snap back to a semblance of reality, the horror of what was happening bringing him into the moment. It took a few shakes of his head to actually think, the implications enough to scare him into fighting back. He had to get out of here, perhaps back to the lab, where he could better focus with his dwindling humanity. Maybe among his research equipment, he could hold onto his sanity, his humanity, enough to…
The sound of urine splashing against the ground gave him pause, looking over at the ape that had been his lab mate holding his dick and pissing all over the remnants of their discarded clothing. He had to admit, even over the pungent stink of piss, the action was rather funny. Of all things he could do in this situation …Joel started to hoot his excitement, pulling out his own dick and relaxing his bladder until an even longer stream crossed the other ape’s. Both hooted like it was the funniest thing in the world, even as some of the splash got on their legs and caught in their fur. In the moment of stupidity, it was simply too funny!
Dizzied by the heady stench, Joel lost track of what he was doing, rather more interested in what the other ape found so fascinating. Curious, Brent was inclined to reach up with his foot, teasing the surface of his cock with a flexible toe and grunting his lust. With his ass in the air, Joel couldn’t help but join in, sniffing the mate’s rear already stained with his seed from their earlier romp. Curious, Joel reached out with his tongue, tasting the puckered flesh and making the other ape moan. In his moment of need, Joel saw nothing wrong about what he was doing, determined to drink in all this ape was offering. He had been worried about…what? He had been Joel…a…human? No, that wasn’t right! He wasn’t…who? What was his name? What did a name mean for a virile male such as he!?
Only a brief hesitation crossed his mind as he continued to rim the other ape, savoring the sensations as he had once before. It felt as though something pressing had been on his mind, something he couldn’t quite place no matter how much he struggled. Still, the pleasure he was getting from rimming the beta male was more than enough to keep his attention. He let himself get into the act, feeling his own cock leaking from the implication. With surprising flexibility, he was able to reach his feet up to jerk himself off, balancing as he ate out the ape’s ass. Eagerly, the beta male let out a howl of release as his cock went into orgasm, spraying all over his dirty foot. The pressure against his tongue was sublime, and the alpha jerked himself off with vigor, wanting to join his mate in bliss. A hoot of excitement left his mouth as what remained of his human mind seemed to ooze out of him like the semen from his testicles. And he was left a quivering mess, awash in the pleasure and filled with the anticipation of the now, body still eager and ready to go after a moment’s reprieve.
The sensation of his face pushing out the rest of the way was barely felt, save for the sight of it in his vision, where it should rightly sit. His heavy nostrils drank deeply in their combined musk, bringing his cock to bear once more. His already pronounced fangs grew even larger, and the ape he was becoming, took pride in the fact his own were larger than his mate’s. He would be the dominant one in their relationship, making the beta submit to him in any way he required. As his beard itched and merged with sideburns and the formerly human hair atop his head, the alpha ape could only think to beat his chest in dominance. The other ape responded by hooting his approval of his lower place in their troop, wanting to service this more powerful male.
With that, the beta male moved to rim his alpha’s asshole, a sensation that pleased him, sending a wave of pleasure through his prostate and making him leak. Experimenting with his new flexibility, the alpha moved to lick his beta’s asshole too, hooting his reverence as he did so, Even as their bodies enlarged and their statures increased, the alpha was easily able to keep up his oral ministrations. His beta did the same and brought them close from the oral stimulation alone. It was certainly enough to erase those pesky stirrings in his mind, ones that confused him but were ultimately ignored.
Still, their eager tongues were not enough to bring either ape to release, and eventually, the alpha pulled back, eager to take what he required. With his beta’s pucker moist and relaxed, he was easily able to enter, his mate’s rectal muscles clamping on his cock and bringing him close to the edge already. The alpha fucked like the beast he was, hooting and howling under the full moon as his thick testicles slapped against the beta’s. The beta was able to use his feet to stroke off, flexible toes much better than his hands as his release built. Yet, the subservient male was keen to let his alpha finish first, and the alpha in his ass had no inclination to hold back. Reaching down to bite into the male’s neck, the alpha felt his release wash over him, filling his beta’s bowel with thick spurts of semen. For the beta, it was a good pain, and he hooted in tandem as his own orgasm hit, spraying what felt like one of a dozen loads over his chest and finally falling into a state of contentment as his alpha pulled from his asshole.
The reek of musk and cum burned into the ape man’s nose, relaxing him and leaving the fringes of doubt in his mind to float away. He was here with his mate, he had gotten off, and there would be no going back this time, his form and instincts permanent. What that meant to his devolved brain, the ape could hardly comprehend beyond that sense of satisfaction. It mattered little in the end, body full of energy and requiring multiple sessions to quell it.
Yet, even with the other ape to satisfy his needs, a new inclination crossed the alpha’s mind, one that made him hoot in anticipation. It was a desire to spread his seed, his essence, to find others who were not like him and make them mates as well. Even without understanding such as possible, the compulsion to find, hump, bite or piss on an unsuspecting human was paramount. And under the light of the full moon, they were sure to find many victims to aid with their devolution into beastly pleasures…
