Ari sighed as he walked down the concrete path, trying to keep his head down in order to avoid eye contact with others as he made his way back to the dorms. It had been two months since he had come to college and while he knew that there would probably be some amount of grief for being a freshman the experience so far had been less than pleasant. Not only had he been called out for being new but several of the athletes who were supposed to help with their orientation seemed to delight in teasing him for the fact that he wore thick glasses and was a bit chunkier than most. He had hoped that he would be leaving such things behind when he had gotten out of high school but it felt like he was in it all over again, just with longer walks to get to classes and living with a roommate instead of his parents.

At first it seemed like Ari had managed to get through the gauntlet of passageways that connected the buildings without any trouble, but when he got to student services he heard a voice that made him cringe. “Hey there tubs," the one named Simone jeered as Ari suddenly found himself get spun around. “If you're looking to stuff your face than the cafeteria isn't open yet, you'll just have to go back to the trough at your dorm."

Of those that for some reason seemed to target him Simone was the worst of them all; he was on the varsity football team as the quarterback and most of the students, as well as nearly the entire faculty, worshiped the ground he walked on. He was also always flanked by at least two members of the football team, and as Ari looked up he saw that it was his usual friends Lance and Wayne. They were linebackers and were built as such, the two almost all muscle and provided Simone with even more protection as they laughed at what their leader had said. As the freshman looked around for some sort of possible escape he could see the faces of the other students as they walked by, most of them either looking away or giving a sneer of their own as Simone continued his verbal beratement.

“Hey, you paying attention or can't you hear me with all that lard in your ears?" Simone said with his smirk growing, darting forward and grabbing Ari's glasses right off of his face. “Maybe if I break these you'll pay attention to your superiors, if you can see them."

Though Ari felt his anger rising he knew there was no point in showing it, not with these alpha jocks around ready to torment it out of him once more. “Please give those back," Ari said, trying to sound as submissive as possible so that they would just end their teasing and move on. “They're hard to replace."

“I'm sure they are," Simone said as he brought them up to the light and looked through the lenses. “What did your guy use for these, car mirrors? Don't worry, I wouldn't break your lenses…" Ari saw Simone hold the glasses out for him to take, but as Ari reached up to grab them he heard a sickening snap as the other man twisted his fingers and broke the bridge in have. “Oh whoops, butterfingers."

Simone tossed the broken glasses to Ari and then motioned for his muscle squad to follow him, leaving him holding onto the pieces. He sighed as he continued to stand there, waiting for the three to disappear down the hallway before he began to move again. As Ari looked at the damage he guessed that he had received some sort of mercy that it was just the bridge, but it was going to be months before he could get new frames and that meant having to tape it up as a stopgap until he could. If he didn't look like a nerd before, he thought to himself with a sigh, he was going to certainly be seen as one now as he quickened his pace to get to the relative safety of the freshman dorms.

The one solace that Ari had was that the random roommate lottery that he had participated in at least had given him someone that was pretty nice, seeing the other guy sitting at his desk in their shared room as he got back in. “Hey Ari," his roommate said, looking up briefly from his book before doing a double take. “Oh hey, what happened to your glasses?"

“Hey Luke," Ari replied as he moved to his own desk on the other side of the room, which was not big and had them almost sitting back to back with one another when they were both there as he showed the other man the two pieces. “Had a bit of trouble."

Ari could see Luke's face turn down into a scowl as he picked up the two broken pieces and looked at them. “Let me guess, ran into Simone again?" Luke asked, Ari sighing and nodding. “You seriously need to report his ass, this is getting out of control. I get not wanting to go out on a limb for teasing you but this is destruction of your personal property and who knows how much more he's going to escalate."

“You and I already know what's going to happen," Ari stated as he crossed his arms. “I'll get called into the office with him, the admin will take the side of their star athlete, and then I'll get my own ass pounded on for the rest of the year. Remember that other freshman that tried to report him when they dunked his head in the toilet, they let him off with a warning and Simone bullied him so hard he dropped out."

Luke just shook his head and went back to studying, which prompted Ari to do the same as he set his backpack on the table. Though he knew his roommate meant well he wasn't the one being teased or bullied, he was on the track team and while he wasn't varsity he had good enough placement that he was regarded as an asset. More than once he had even offered to use that clout in order to try and get Simone and the others off of his back but Ari didn't want him to stick his neck out, especially since he was on scholarship and too much trouble could cause him to lose it. As this point all he could do was grin and bear it, though if it got worse perhaps he could just drop out himself and try again in a year when those guys had graduated.

As Ari went through his mail, one of the reasons he had gone to the student services building in the first place, it was mostly the usual garbage that came to students such as notifications for special events and billing statements. When he got to the end however he found one that was in a bright yellow envelope that didn't have a return address on it. He also found it to be quite heavy and at first he thought he had gotten someone else's mail, but after repairing his glasses he read the name on the front and saw that it was for him. His curiosity getting the better of him he decided to open it up and pulled out a small stack of papers that didn't seem like they would fit inside of it, along with a separate letter that he opened and up and read.

Dear Mr. Perez,

Greetings, we are pleased to inform you that you have been selected among your fellow students and peers to be a part of a trial for a new and exciting series of products that have been formulated for people such as yourself. Our products are all-natural and can produce the same results as most steroids, but unlike those that are illegal to use ours has lessened the usual side-effects such as increased aggression or gotten rid of them completely like testicle shrinkage! Not only do you get the benefits of a fit body but also a stipend for being a participant in this trial; if you agree to get involved in the testing please fill out the paperwork below and get ready for your new life, if not than feel free to shred this application or hand it to someone else you believe will want it.

Sincerely,

Sibergon Labs

Sibergon Labs… Ari had never heard of such a place before, though he had never been in the market for supplements and definitely not steroids. It sounded like some sort of hoax or sham but as he looked through the rest of the paperwork it felt like it was professionally done by lawyers as he read various clauses such as an NDA and intellectual property rights. When he got to the last page it was where he had to sign as well as pick the regiment that he wanted to be a tester of, which involved picking what sort of attributes he wanted to increase which had animal names next to it. Most of the legal stuff was gibberish to him, but since Luke was studying to be a lawyer he decided to get his roommates attention and show him what he had just received.

Ari waited patiently as the other man scanned through the note as well as the contract, his eyes widening when he got to the last page. “Well I see what you mean when you said that it looks like it's too good to be true," Luke finally said as he shifted the last page back and forth to see if there was any other information on it. “This is the actual contract, everything else is an explanation of it as well as benefits."

“But it's got to be a hoax, right?" Ari replied as he took the paper back and pointed at the list of products. “They say that their bear pills can actually make you taller as well as extremely muscular, or their wolf pills to give you increased senses like smell and hearing!"

“Well… there has been a lot of advances in medical science recently," Luke said as he went over to their shared printer and scanner and put the sheet inside. “Let me make a copy so that I can help you research it. I don't know about this Sibergon Labs but if they're an actual company with reputable business and government standing it might not be a bad thing. At worst you get some money for trying out sugar pills and at best, well…"

Luke's sentence trailed off but Ari knew what he was about to say, that perhaps it was a way for him to lose some of the weight that had drawn the ridicule of Simone and the others. Once Luke had finished making a copy for himself he handed the original back to him, then said that he was going off to the computer lab to finish a paper. Ari nodded and watched him leave, then decided to make himself something to eat before he got to work himself. Since all they had in their dorm room was a microwave that meant a cup of noodles, which he knew was not aiding in his weight loss but didn't want to go back to the student services building to get an actual meal.

As his food was cooking Ari looked over the sheet that had been given to him, and though he knew that he should just put in his drawer and start studying he couldn't help but look over what the company boasted its supplements could do. It wasn't just physical attributes either; while most of the pills did boast some sort of weight loss or muscle growth component there were also ones that would increase confidence, charisma, libido… the last one caused him to blush slightly. Sharing a room with someone constantly and looking the way he did Ari had never thought about that sort of thing, but even if he did he doubted he would be able to get anyone. The idea of these magic pseudo-steroids still felt like a pipe dream, yet as the minutes ticked away he found himself pulling out a pen and starting to write his name on the first line…

About a week later Ari had walked back to his dorms in a hurry, trying to move as fast as he could without drawing attention to himself. Other than a few encounters with Simone and a few others the week had been rather quiet, at least until he had gotten to the mailroom and saw that he had a package delivered to him. With the bubble-wrapped envelope underneath his coat pocket he raced back to his dorm and nearly slammed the door shut behind him. He knew Luke had classes for the next hour and the dorm was all his as he took the package out from beneath his coat and ripped it open before dumping the contents onto his desk.

There was a loud rattling as two bottles of pills fell against the wood, followed by two slips of paper. When Ari examined the bottles there were no markings other than a silhouette of a hyena on one and a shark on the other. The contract stated that he could only take up to two regimens at a time and they had almost all the attributes that he wanted from them. When he examined the check his eyes widened when he saw that it was for a thousand dollars, which made this whole thing worth it as he set it aside before picking up the other one. It was merely a thank-you note for testing the product as well as the simple instructions of taking one of each pill a day until the bottles were empty.

Ari set the sheet down and looked at the two bottles once more, shaking his head slightly as he shook the contents within. There was probably enough inside each for two, maybe three months' worth of pills, and as he had found out through his research while waiting for this package he found even injectable steroids took longer than that and required other factors as well like constant exercise. When he and Luke had looked up the company that was attached to it though they did find the website and saw they were highly recommended and leaders of scientific research, as well as accredited by every agency on the planet. In reality even if it was shady Ari was probably going to take the pills anyway, shaking out one of each into his hand as he looked at the red and grey capsule, if there was even a chance to end the torment from his abusers he would take it plus the money was a nice bonus.

After getting a glass of water he swallowed down the pills, then looked at himself. He could almost feel the capsules traveling down his body and as he pinched one of the rolls of fat on his stomach he cursed to himself. “Even they didn't say it was going to be instantaneous," he chided himself as he went to his desk, hiding the pills in a drawer before looking at the check. “At least I'll be able to make my bank account bigger."

As the day wore on Ari continued to feel no effects for good or ill except for a slight stomach ache which only lasted a few minutes. He still hadn't told Luke that he had gotten the pills, not wanting his roommate to worry about him for taking some sort of strange experimental substance, and fortunately his roommate didn't bring it up with him. By the time night fell Ari still had noticed nothing new about himself other than the fact that when he looked up his bank account he was four figures richer as the check cleared. That gave him some motivation to continue since he was also promised five thousand more dollars if he continued to the regimen to its completion.

Over the next few nights one peculiar thing did keep happening to Ari, which was that he would suddenly wake up and find himself covered in sweat and panting. From that point until the rest of the night he found himself unable to go to sleep and would often spend the time in the shower, but when the next day came around he found himself not fatigued by getting less sleep. In fact he almost felt overly anxious, like he had to keep moving around to burn off excess energy as he got through his first few weeks of pills. He soon found himself starting to go out on the trails more to have a run, especially during the night after waking up, and during the day he started going more and more to the fitness center to use the pool just to keep from vibrating in his seat during classes.

The problem however was the fact that when he went to the fitness center he was going into the lion's den, though he often wouldn't wear his already broken glasses to keep them safe. In essence he had already found them to be quite bothersome; even when he wore them things were starting to get fuzzy and the last thing he wanted to do was make an optometrist appointment in the middle of the semester. At least it was one less thing that Simone could break, he thought to himself as he made his way towards the pool locker rooms. Once again it was almost the middle of the night and the fitness center was almost empty despite being open twenty-four hours a day, but as he felt a hand grab his back and shove him against the wall he realized he wasn't as alone as he had hoped.

At first he thought that Simone had somehow caught him, but as Ari was spun around he saw that it was a guy dressed in a wrestling singlet that he recognized as Walt. “What do we have here?" Walt jeered as he got right up in Ari's face. “You're Simone's little bitch boy, aren't you? The four-eyed fatty."

“Fuck off, asshole," at first Ari wasn't sure who had said the words but as he looked at the surprised look on Walt's face he realized that it came out of his own mouth! He could feel his eyes widen in shock but tried to keep his composure as he watched the other man's face turn red before he burst out laughing. “What's so funny?"

“Looks like there's a spine within all that dough after all," Walt replied with a sneer, glancing down the hall before leaning in. “If coach wasn't still around I'd beat it out of you, but I guess a warning will have to do for now. Just make sure if you try that with Simone that I'm around so that I can find some of your teeth and get a little cash from the tooth fairy."

Though Ari could feel the rage burning inside of him he said nothing, flinching slightly when Walt thrusted his chest towards him in a faux tackle before moving on. Ari contained his composure for as long as he could and managed to contain himself until the wrestler move on towards the other area of the fitness center for whatever late night practice is going on. As soon as the other man was gone though he turned and smashed his fist against the wall, letting out the breath he had been holding in heavy pants. Even though he had been terrified in the moment it felt good to call him an asshole, because that was exactly what he was as he banged his other hand against the wall before bracing himself.

But the rage wouldn't subside, feeling a heat rising up in his body as he began to feel his body shake slightly and especially in his arms. When he looked up at them he could see the veins underneath his skin pulsating as he spread out his fingers from where he had made impact, watching as the skin began to shift slightly. At first he thought that it was just from wearing his glasses but he remembered he had already taken them off, and yet his vision was clearer than ever as the skin of his fingers turned grey while his fingernails got a red glaze over them. The discoloration quickly spread up his forearms and as he backed away from the wall he could see his biceps not only start to swell but have the hair on them grow thicker and start to turn a deep shade of red as well.

Even with his arms changing and growing Ari still found his focus getting drawn back to his previous encounter with the wrestler, which eventually bled into all of the times Simone and the others had bullied him. He felt a snarl escape his lips as his anger grew and became more generalized while he continued towards his original destination. He pushed on the door hard enough that it flung open and cracked against the back wall, though all he could focus on was his clothing. Ari still had his normal clothes on over the swim trunks underneath and both his shirt and pants began to feel tight against his body as he walked inside.

Despite heading to the fitness center Ari had worn a button down shirt, and with his fingers becoming thicker he found it harder to get them to undo the buttons that were starting to strain as the fabric stretched around him. With another growl of frustration Ari just grabbed it and ripped it off of his body, exposing his chest and revealing the light red fur that had started to grow down his stomach. He did the same thing with his pants and as he felt the relief of no longer being confined it gave him a momentary abatement to his anger, and as he looked down at himself his eyes widened in surprise. The flab that had hung unflatteringly against his body seemed to suck into his body as his sagging chest firmed up right before his eyes, and even as the fur covered it he could see his flattening stomach start to get bumps again but instead of it being pads of fat it was a set of muscular abs while similar strengthening was happening to his back and shoulders unseen.

“I'm… I'm a monster…" Ari said, but as he watched his form continue to change the shocked look on his face began to shift into a grin, then a wide smile to reveal his sharpening teeth as he began to laugh. “I'm a monster!" As Ari's voice deepened his laughter turned to cackling as he flexed his arms, then brought up his leg and kicked it into one of the locker doors. The metal caved under the force of the blow as he saw that his feet had under gone a similar change like his webbed fingers, watching two of his toes merge together as the rest swelled into heavy webbed feet.

As he continued to watch his calves and thighs thicken with new muscle growth Ari fell forward into the lockers as his spine popped and stretched, adding new height that pushed his increasingly fur-covered face into the lockers. The sensations merely caused him to laugh even more as he imagined Simone trying to face him now, his mind being filled with images of exactly what he could do to him while he felt something start to push out of his back. The feeling of his new finned tail stretching out of his body caused him to pant in ecstasy, the lust mingling with his rage and creating an intoxicating feeling as his claws dug into the already damaged locker. As he felt the new appendage thicken he pushed his entire body forward into the cool metal as though stretching, and as he did he felt his cock surge with new growth and slide up between the locker and his fur-covered abs.

Ari's laughter was cut short as he suddenly felt his jaws stretch, the already tooth-filled maw growing into a proper muzzle as he brought his hands up to his head from the flood of thoughts swirling around inside of it. Power… dominance… pleasure… rage… so many things he knew he could satisfy now as he felt his ears stretch up between his fingers and push to the top of his head. He found himself at a loss for words but found such things unnecessary, especially when he saw the reflection of his body in the mirror as his jet-black cock throbbed in the air.

Just as he was about to go over and examine himself however Ari heard the door to the other side of the locker room open, the one that lead to the pool. Maybe it was Simone, his lust-tainted mind thought as he felt a spike of rage surge through him, or possibly Walt. He felt his entire body shudder at the idea and his muscles seemed to inflate a little more as he let out a snarl and made his way to the source of the sound. Even before he got to the other end of the locker rooms he heard a voice that was neither of them, nor was it anyone else that he would want revenge on as he peeked around the corner as well as a seven-foot tall hyena-shark hybrid could do.

It appeared his laughter and banging around had not gone unnoticed as Ari watched the wet human walk in and ask out loud if something was going on. As the beast sized up the other man his claws dug slightly into the metal, but this was due to the fires of lust instead of anger as he noticed the athletic build and handsome features of the swimmer. The swimmer was clad only in a speedo and from the bulge that he was sporting he was fairly well-endowed, though Ari noted that he had nothing on his own thick member that still jutted out from his thighs. He wanted him, desired his body, and with that being the only thought in his mind he waited until the guy had turned away from him before he moved forward.

Ari had managed to get nearly up to the swimmer before the slaps of his webbed feet on the wet floor notified them that there was someone else in the locker room. When he turned around Ari whipped his tail around to keep the guy from falling over as he backed away in sheer shock and nearly tripped over himself. “Relax," Ari said, his new deeper voice a rumble as he remained standing still so the other guy could drink in his presence. “If I wanted to hurt you I would have."

After the initial shock had worn off Ari continued to keep his tail supporting the swimmer whose mouth opened and closed a few times before any words came out. “I… damn…" the swimmer said as he finally started to form cohesive thoughts again. “What are you?"

“Not important," Ari replied as he licked his chops before giving the other guy a coy grin. Whether it was the physical transformation or another side-effect of the pills he had never felt more alluring than before, and even with his hulking and extremely inhuman nature it was clear his smooth words and demeanor were having an effect on the other man as he watched the bulge contained within the shiny material of the speedo began to twitch. “Swim with me… it'll be fun."

It took everything for the monster not to chuckle as he watched the swimmer swallow hard, then look over his naked body. To help with the decision Ari leaned seductively, being careful of the dorsal fin in the middle of his back, and put his muscular form on display while using his foot to slide against the groin of the other man. He could smell the arousal on him and it was only growing more potent as he used his foot to tease him, using the flexible fingers and webbing to grope his body while he waited. It didn't take long for the swimmer to nod and Ari darted forward, picking up the surprised swimmer before going out into the pool area with him in his muscular arms.

The surface of the water was still as there were no other swimmers, though that didn't matter to Ari as he took the one in his grasp and threw him into pool. If there had been anyone else he would have just fucked them too, but one was enough to slake his lusts as he dived in immediately after. Fortunately the campus had gone with a salt water pool as he felt the new gills on grey areas of his neck open, Ari looking up to see a pair of legs kicking above him. With his new aquatic features Ari was able to easily propel his muscular body up while keep out of the gaze of the other swimmer, who didn't only saw the red-furred beast when he came up and pulled down the front of his speedo.

This one was very eager, Ari thought to himself as he opened his muzzle and licked his tongue against the throbbing cock that was presented to him. He felt the other guy thrash in the water and felt a pair of hands against his head, but with his gills the creature beneath had no need to worry about air as he drew the sizable shaft into his maw and began to suck on it while being careful of his teeth. It didn't take long for the swimmer to start thrusting forward as Ari's muzzle completely engulfed it, able to easily take it in as he swirled his tongue around the sensitive flesh. Even with his ears under the water he could hear the other man say something about being blown by a sexy shark monster, which caused Ari to smile before he felt the swimmer about to cum and pulled off.

With a powerful kick of his feet Ari swirled around and came up around behind the swimmer and grabbed his arms. He could feel the human jerk slightly as he lost the ability to tread water but the hybrid beast knew he could keep them both up with his tail alone as he used his foot to pull down the speedo completely to exposed the rear of the other man. Even though his arousal was at its peak he knew not to hurt this guy and slowly pushed the head of his cock in, using that same webbed foot to press against the human's groin and stimulate the hard member he had been stimulating moments ago with his maw. It took a few minutes, the two of them floating together with the swimmer pressed against the furry muscular chest of the beast behind him, but with a gasp and a snarl Ari managed to get several inches of his thick shaft inside and started to pump his hips.

The water rippled around them as Ari continued to hold the naked swimmer's arms up, leaving him helpless in his grasp as he began to thrust in a little deeper each time. The feel of completely dominating the creature was euphoric, and since there was no previous animosity with this particular athlete he was able to fully enjoy carnal act between them. It didn't take long before he felt the hole that he had stretched open clamp down around him as the cock he had been stroking with both his webbed feet had cum, the swimmer moaning loudly as he orgasmed right there in the pool. Ari had been holding back his own climax until that time and he pushed in one last time before he came inside the other man, feeling the new knot of his cock bump up against the cheeks of the man as he let loose a series of snarls.

For a while Ari continued to keep the swimmer wrapped up in his arms, rubbing his smooth fingers over the other man's chest before feeling a hand caress his muzzle. “Can't believe I just had sex in the college pool with a monster," the swimmer said, causing Ari to laugh. “Is this a dream?"

“It's not," Ari replied, though as he did he felt his voice crack slightly. His eyes widened as he began to feel his cock inside the other guy do more than just soften, it was shrinking as his washboard abs began to get covered in a layer of fat. “Hey, I have to go, I'll catch you again prey."

Before the human could answer he gasped as Ari pulled out of him, then let go and began to swim for the shore. He glanced back and saw that the swimmer was fine and going after the speedo that had floated away, which was good for him as he hopped effortlessly up out of the pool and into the locker room. With his clothing shredded all he could do was try to run back to the dorm in time, but with every step he took he could fell his stature shrinking and the muscles propelling him forward disappearing along with the strength and speed they gave. With it being so late in the night though there was fortunately no one around and when he got to his dorm he punched in the code to get inside just as the last of the fur receded from his body.

Ari sped his way up the stairs and down the hallway before once more punching in a code, this time for his own room as he carefully but quickly opened the door. The inside was pitch black and he could heard the soft snoring of his roommate, something he had become accustomed too as he got inside and softly closed the door behind him. He grabbed a pair of pajama bottoms that had been on the floor and tried as stealthily get up to the top bed without waking Luke. When he got onto his sheets he didn't hear any difference coming from the one beneath him, breathing a sigh of relief that he had gotten in unnoticed.

“Can't sleep again, huh?" Luke's voice caused Ari to shake as he called up.

“Yeah, I suppose not," Ari replied after he got his heart to stop racing, flopping down on the bed before his face contorted in confusion. “Wait, again? How often have you noticed me going out?"

“For a while actually," Luke replied. “Something wrong?"

“No no, just not tired," Ari explained. “I'm fine, you can go back to bed." As he laid there waiting for a response it didn't take long before he heard the soft snoring again as he looked up at the ceiling. In reality he hadn't even lied to Luke, he had felt better than he had his entire life… though the fact that he had lost control like that when he turned into that beast was disconcerting, more than his actual transformation it seemed as his brain seemed to gloss over that he became a monster. That primal rage, and also the lust that came with it, was like he was trying to surf a tidal wave, and as he laid there in his bed he knew that he was probably in for another sleepless night as he rubbed a slightly clawed hand against his groin.

The next morning came around though and once again Ari felt great with his bestial night feeling like a dream, and as the days progressed the encounter in the locker room and pool seemed to evaporate from his mind. He continued to take his pills and found that he was about halfway through the bottle already, which surprised him at how much time had passed. Not only was he starting to look much better than before, his clothes starting to no longer fit him with his weight loss, but he just felt more confident than before. There was a swagger to his step that he never even knew he could develop and he also began to notice that he was eyeing up other guys far more often than he had used to.

One thing he did take care not to do was anything that would provoke that beast from coming out again, avoiding athletes like the plague when he could and trying not to get riled up. Though he wasn't getting angry he found the supplements were affecting one other aspect of his life that he hadn't expected, ramping up his libido and prompting him to find places to masturbate and relieve his need. As he had gotten back to his dorm late one night after one such session he noticed that he had gotten another letter from the company that had made the pills, this one much thinner than before. Had they already mailed him his second check, Ari wondered as he got to his desk and ripped open the envelope.

What he found instead was a warning from the company about additional side-effects that people were experiencing, Ari's eyes growing wide when he saw turning into a beast as one of them. Had they somehow known about what had happened to him? It seemed like the letter wasn't specifically addressed to him though and instead was just a general warning, but he got to the end he felt his heart drop to his stomach. It had advised that if he had experienced such things to stop taking the supplements and warned of the possibility of further mutations if side-effects persist, which made him crumple up the letter and open the drawer where he kept the bottles.

Mutations… that was a strange word for it, Ari thought to himself as he shook out one of the pills from each bottle and looked at them. So far he hadn't turned back into the beast and he had found after using one of the scales in the gym that he had lost almost forty pounds, which was probably more since he had also started to gain muscle definition in certain places. He had also found that his eyesight had started to clear up too to the point where he didn't even need his glasses anymore. Would all that be reversed if he stopped taking the pills, and could he go back to being that guy again?

Just as Ari popped the capsules into his mouth and swallowed them Luke came bursting into the dorm, tossing his backpack on the side of his desk before turning to Ari. “Hey, you're not going to like this," Luke said, his words coming out quickly as he showed Ari his phone. “Someone just posted this up on a public board of the college."

It took a second before Ari saw what he was looking at, his jaw dropping as he saw the image of his head photocopied on the image of a huge pig with the words calling him the new class mascot appearing underneath. Luke had started to talk about how he had already talked to the college to take it down but they couldn't, but all Ari could focus on was the name of the one who had posted it. Walt… the bastard hadn't even tried to hide his name because he was a star wrestler and knew nothing would come of it. As Luke began to talk about potential legal recourse Ari just stood up and pushed Luke back before rushing out of the door, already feeling fur starting to grow all over his body as he rushed out into the night air.

Meanwhile at the fitness center Walt had just finished up cleaning the wrestling mats, taking a second to take a drink of his water bottle while waiting for the soft foam to dry before he could roll them up and put them away. With him being alone the only sounds that could be heard were the soft hum of the electric lights and the sound of the clock ticking to remind him how late it was. “Thank god it's Friday," Walt said to himself as he went to take another drink, only to drop his water bottle and stand up when he heard a loud bang that came from the area of the locker room. “Hey, what's going on in there!?"

There was another loud sound of crumpling metal, followed by a second bang that caused Walt to jump slightly. Something was definitely coming his way and as the noise grew louder it prompted him to look over at the other exit door that was in the room. Before he could decide to move towards it however there was a loud crash as the door to the locker room was kicked open with such force it knocked it off one of its hinges, hanging in front of the huge beast that let out a snarl. “YOU!" The creature practically roared, Walt's face contorting in panic as it started to charge right at him.

Walt only made it about halfway across the mat before he was tackled from behind as Ari lunched forward and smashed into him. Though the wrestler was built solidly his legs crumpled from the bigger creature's weight on top of him and they both went crashing to the ground. “Help!" Walt cried out. “Someone get hrpphfp!"

Ari quickly silenced the human by twisting around and pressing his feet against Walt's face while using his arms to grapple his prey's legs together. “You think posting something like that is FUNNY?!" Ari snarled as he pressed his clawed hands against Walt's stomach, his claws pricking against the spandex singlet he wore as he felt the human squirm beneath him. “Maybe I should make you squeal and see how much of a little piggy you are!"

Once more Ari felt the vibrations of Walt trying to say something, the beast seeing the look of realization on the face at who he was. That was almost as satisfying as the terror that he inspired in his tormentor as he kept his feet on his face, enjoying the sensation of the human trying haplessly to speak while his webbing was practically suctioned against him. The beast found a certain irony in having this powerful wrestler bound in his clutches, feeling his muscles strain to attempt to get out of the hold that he was in with little hope of escaping. As he decided what to do next however Ari's eyes widened and his nose sniffed the air as smells drifted in that he hadn't been expecting.

Arousal…

Desire…

And most interesting of all, dried cum… two sets of dried cum…

Walt paused his struggles as the creature that was holding him suddenly broke out into wild laugher, feeling the beast's entire body getting into it before Ari snapped his head down and looked at him with wild eyes. “So that's the kind of late-night wrestling moves that you've been practicing," Ari said as he gave Walt a toothy smile. “Who are you pinning, or being pinned by, another wrestler? The coach?"

Ari could feel the human convulse slightly at that and that was enough for the beast to let loose another round of cackling. “No wonder you're so good with all that extra practice!" Ari said as he lowered his feet down, this time pressing them against the spandex-covered pectorals of the other man. “I can see the headlines now, star wrestler caught having sex with coach. Would make a better post than that crap you had."

“Wait, Ari!" Walt said, his terror at the muscular beast pinning him quickly replaced with a different kind of fear. “I'm sorry that I made fun of you, honest! I just did that because I thought you were snooping around and wanted to get rid of you, I swear I won't tell a soul what you are or make fun of you ever again! Please, if this gets found out I'll lose my scholarship!"

“Not a bad offer," Ari growled, licking his chops. “Tell you want, if you can prove to me how much you want me to not tell anyone we can discuss not letting your late-night sparring out in the open."

With their bodies pinned Ari could feel the sense of relief the other man had. “How?" Walt asked. “I'll do anything."

“Oh, I know you will," Ari replied as he once more put his feet up in the face of the wrestler. “Start by licking my feet, and we'll go from there. Now you're MY bitch."

Walt just nodded and as Ari felt the tongue of the other man it caused his cock to surge and his back to arch. He had never been one for such things but the feel of stimulation against his webbing and the subservience that came with it caused him to let out a moan. His furred body practically convulsed when the wrestler moved to suck on one of his clawed toes, licking around it and causing the beast to writhe in pleasure. This one definitely had a skilled mouth, Ari thought to himself as he shifted his position and moved both him and Walt so they were chest to chest with him on top, it made him wonder what other holes the coach had been training him with.

That question was quickly answered as Ari slid his hand down the spandex-covered chest to between Walt's muscular thighs, only to find when he got there that the claw he was going to use to slice the material open over his tailhole had already been done for him. “Oh my, prepared and lubed," Ari commented, chuckling when he saw Walt blush as he pushed his finger inside. “Give my regards to your coach for preparing you for me."

Walt was about to say something else but when he opened his mouth Ari darted down and pushed his hyena muzzle against his lips. The mental image of that post still burned in his mind and he wanted to make sure this prey knew who was the predator as he shoved his tongue into his mouth while also lining up his cock and sliding the head into the spandex singlet. As his kisses became more hungered Ari began to feel his tongue tingling before it felt like it was starting to swell, but all that allowed him to do was push it in deeper while feeling the human suck against it. He could hear Walt let out a muffled grunt as the growing appendage began to press up against the back of his throat, but at the same time Ari pushed into the lubed opening of the wrestler and sank several inches of his throbbing shaft in all at once.

The ring of muscle yielded easily to him and even in his lust-fueled craze Ari could tell the coach definitely trained him well. As the beastly creature crunched up his abs and spread open the insides of the human however he found his attention being more focused on his tongue. It was almost twice as long as what it had been even in his transformed state and as the tip began to push into the throat of the human it was growing extremely sensitive. Eventually curiosity overrode lust and Ari pulled back, pressing his clawed hands against his muzzle as he saw the foot-long cock tongue spreading open his lips!

Ari heard a gasp from beneath him and his head snapped down to see Walt staring at the strange mutation with wide eyes and an open mouth, asking what was going on. “Did I say you could speak?" Ari snarled, the beast manifesting once more as he leaned in after the human shook his head until the new tip of his cock tongue pressed against his lips. “Time to use that skilled mouth of yours for more useful things than talking, I'm going to stretch your throat just like your ass."

Before Walt could say anything Ari lowered his muzzle back down, his body trembling as it felt just like his maleness was being sucked. In the back of his mind he remembered something about mutations, but none of that mattered as he also began to thrust his hips deeper in. Soon he developed a rhythm where he would push his head down in time with his groin, penetrating the wrestler who writhed intensely beneath him from the stimulation. Eventually Ari managed to not only work his knot into the other man but did get his new cock tongue into the throat of the other male, the beast looking down to see the stretching of Walt's stomach and neck before letting loose a torrent of cum inside of him.

Walt gurgled as he was filled from both ends, the beast keeping him pinned as he was filled to the brim while the knot inflated inside of him and kept them tied that way and Ari used his hand to keep their lips locked in the bizarre kiss. After a few minutes though Ari could feel the rage and lust that fueled his transformation was ebbing and needed to pull out, wanting to get back to the dorm before he had to streak across the campus as a human. “So do we have a deal then?" Walt managed to say, his voice croaking slightly from the cock that had been inside of his throat as Ari stood up and stretched his powerful body. “You won't tell anyone?"

“Get the rest of the wrestling team and whoever else to stop teasing me," Ari replied with a growl as he went to the exit door he hadn't destroyed. “You do that and your secret will be safe with me. Oh, except for Simone, I'm looking forward to teaching him a similar lesson."

Walt just nodded and Ari left, making sure the coast was clear before running out into the late-night air. It had been getting close to mid-terms which meant that even fewer people were out, which was a good thing considering that he was finding his body transforming back much slower than before. By the time he had gotten back to his dorm room he still had a layer of fur covering his body as well as the tail, muzzle and ears, which along with that came the cock tongue he had developed during his last encounter. The mutation thing was real, Ari realized as he snuck to the common room and went to where he had stashed his clothes before running after Walt, and he wondered if it would become worse if he became his inner beast again. Not if, Ari reminded himself as he got dressed, knowing that he would unleash it once more just to teach Simone a lesson he won't ever forget.

Ari found himself unable to go to sleep after that, though by this point he had gotten so used to it that he just spent most of his nights either out studying or walking about. It didn't seem to affect his health at all and Luke didn't seem to mind, especially since he was starting to move up in the track world and was spending more time out of the dorm himself. He also noticed that the post from Walt had gone down and that the wrestling team no longer bothered with him, along with several other athletes. That still left the football team however, but the more time went on the more he was looking forward to the next time Simone messed with him, which was possibly why he hadn't bothered him yet.

As Ari sat in his desk Luke practically barged into their dorm once more, hopping up and down as he ran about. “I get to run in the sectional finals this year!" Luke said rapidly as he quickly got undressed, not even bothering to cover up as he went from his normal clothes to his track outfit. “He says that he wants me to take a drug test first but I'm totally going to pass and then I'm going to race and that's so exciting and I can feel my heart racing but that's weird because I totally quit caffeine so I have to go now Ari see ya later!"

Ari was at a loss for words as he had trouble tracking what Luke was even saying as he shot back out the door like a bullet, causing the papers he had tossed on his desk to fall on the floor. It was how he had been acting for a while and though it concerned him it didn't seem like anything was wrong. He looked down at the papers scattered on the floor and sighed, then decided to be nice and gather them up for his roommate. Once he had gathered everything up he decided to put it in his desk drawer, opening it to put them in until he heard a very distinctive rattle that caused him to stop.

For more than a few seconds Ari found himself frozen as he looked at the desk drawer, unsure of what to do next as he stood there. Eventually he put the papers on the desk and reached into the back of the drawer before his fingers felt smooth plastic and he pulled them out. He felt his jaw drop as he looked down at the two pill bottles, one of them with the outline of a snake on it while the other had a feline figure that Ari guessed was a cheetah from the yellow color. His eyes furrowed as he wondered how he managed to even get these, and as he shook the bottles again it sounded like he had gotten them at around the same time he did.

Unless… there was one way that Ari figured it could happen, but he would have to wait for his roommate to get back to ask…

Ari waited for hours at the dorm as day turned to night, and when Luke still didn't return after getting long past midnight he decided to go out and look for him. It didn't take long to figure out where he was, the first place that he had looked was the indoor track in the fitness center and saw the guy still in his track suit running around. “Oh, hey Ari!" Luke said as he zoomed by, “I'm just finishing my laps, be done soon if you want to talk!"

As the other man went around again Ari wasn't going to wait that long, instead moving over to where there was a pit filled with spongy material for long jumpers and pole vaulters that was next to the track. When Luke came around again Ari pushed him hard, causing the runner to stumble forward and fall into the foam blocks. Luke landed face first and as he shifted around in the loose material Ari waited next to the edge. He heard a growl come up from the pit and when the man turned around Ari saw that Luke's face had started to grow scales and there was spotted fur on his arms as he let out a hiss.

“What the fuck was that for!?" Luke said as he moved over to get up, only for Ari to kick him back into the pit as his shoe burst open at the seams. Ari's own transformation had started to progress and he dropped into the pit as well, grabbing Luke by the shoulders as he watched the man's eyes turn to slits. “Get off me!"

“You sent in that copy, didn't you?!" Ari snarled back, his muzzle growing out as clothes popped from the growth of his muscles as the same thing was happening to Luke's track suit.

“So what if I did?!" Luke hissed back. “What, you have a monopoly on being a monster?!"

Ari brought his hand down and ripped the tattered jersey off of Luke to reveal the ripped scale-covered physique underneath as well as something else that caused him pause. Instead of one dick Luke had two, both them growing as they huffed at one another. Ari's lips curled into a smirk and he showed the transforming cheetah-snake his own mutation, sliding his growing cock tongue into the other's serpentine muzzle. As he did he felt something pushing up between his legs and saw a thick snake tail that had slithered between his spotted furry legs and rubbed against his cock while Luke's feet exploded into huge paw pads. At this point Ari was running on pure primal energy as he turned around and nuzzled those huge foot pads with his muzzle, sliding his cock tongue between those furry toes as Luke shifted himself underneath.

A growl escaped the hyena-shark as one of the two thick, prehensile shafts of the other beast slid into his tailhole, spreading him open while the second one pressed between his taint. Even with his augmented physique Ari found himself being stretched open by the thickening member, his breath catching in his throat with several toes in his maw as Luke penetrated him even deeper. Even so the beast found himself desperately wanting both of them inside, and as his body quivered in pure need he began to feel something happening to his form. A tingling sensation similar to when he had gained his cock tongue, except this time it was between his legs as he heard a chuckle from the other beast.

“Looks like someone really wants me to double penetrate them," Luke said, his voice taking a more seductive tone as Ari felt hot breath between his legs where the sensation was. “Luckily for you snakes can be very… flexible."

“If you're going to fuck me then do it," Ari growled as he felt the serpentine snout press up against his taint. “I don't know what yooohhhhh…" Ari's words trailed off and his face twitched as he felt a new pleasure cascade through his system, one that was familiar but different to the shaft in his tailhole as his cocktongue became completely erect while it pushed past his lips and stuck out into the air. The forked tongue of the beast behind him licked against the new folds of the pussy that had grown in the hyena-snake before arching back, taking the other shaft of his hemi-penis and pushing it inside.

Ari let out a roar as he was penetrated for the first time in his new slit, his body shaking in sheer ecstasy as the other beast stretched open both holes while his swollen cock tongue filled his own mouth. The shark-hyena found himself twisting his body to watch the cheetah-snake pound into him, watching both shafts plunge so deep into him that he could practically feel them rubbing together inside of him. It caused his lust to spike and made him extremely envious, and as he watched his stomach stretch out with each thrust he noticed that something was happening to his own groin. His lips curled into a wicked smile and he began to laugh as he felt his own body responding, a second canine cock stretching and growing outwards until it was buried into the foam blocks alongside its companion.

“Look at you," Luke growled as he raked his furry hands along the dorsal fin and grey flesh of the one beneath him. “You are a fucking beast, no one is going to mess with you anymore."

“You mean no one is going to mess with us," Ari replied with a snicker, then grunting loudly as the words seemed to spur the other beast to drive deeper into his holes. Given how angry Luke got on his behalf it was likely that they were going to team up in order to mess with Simone and his crew, thinking about how he would use his two cocks to fuck each of those muscleheads that he kept with him while Luke did the same with their mouths. They would make Simone watch, bound up in their tails, and when he realized how well and truly fucked he was they would work on him next. Perhaps if the quarterback was a good boy he would ride him with his new snatch, though at the moment the only thing he could think about was stretching him open with as many cocks as he could.

Those thoughts only served to grow his arousal as a snarl came from the one behind him as those luxurious feet paws were pushed into his face. Ari just growled back and let the snake-cheetah continue his thrusting, relaxing a bit as he felt those throbbing shafts inside of him. Though he had been mad that Luke had horned in on his scientific study it was nice to have another beast around, even if it was to slake their lusts. One thing he knew for sure, Ari thought as his grin widened, next time they let loose he was definitely going to be the one on top.
