Being taken to an unknown research facility for tests was rather disconcerting for Ari, given that he was asked to lay on an uncomfortable gurney while several unknown medical workers poked and prodded at his burning body, but it was necessary following the multitude of studies run on him showing that his body was having a strange reaction to the drug he had been given several days prior. Thankfully the staff inside the vehicle treated him with enough respect for his temper not to flare, even if they didn't exactly answer all of the questions that he had regarding where he was going and what exactly would happen to him following the various tests that they warned him he would be undergoing. By the time the hour long drive came to an end the raven haired college student found himself having to pee like a racehorse, this proved quite fortuitous, as the moment he was wheeled into the sterile smelling building he was taken to a lonely room fitted with white padded walls and told to pee in a cup. 

A strong air of confusion overcame Ari's mind as he stared at the plastic cup clutched within his swollen hand, however he rationalized that the sooner he did what was asked of him the sooner they would get him the treatment he needed to get out of there. Going over to the nearby toilet and flipping the lid open, Ari unzipped his pants and then fished out his dick, only to find that it had become both thicker and redder. Shock gripped the young hispanic's heart as he tried to make sense of what exactly was going on with this part of his anatomy, he slowly settled his racing heart once he flexed his inner muscles and found that everything worked as it was supposed to. Moving his hand across the tip of his angry looking shaft, Ari found himself hissing as he noticed just how sensitive the skin wrapped around his meat had become. 

Thrusting his hips forward without meaning to, the raven haired college student found a wellspring of tingles running up throughout his backside as he slowly began to jerk himself off. His tongue lolled from out the side of his lips when he opened his mouth to pant in growing pleasure. A sharp hiss escaped from his mouth upon him rubbing a thumb across the head of his cock, pre-come slowly began to leak out of the hardening pillar of flesh as the seconds ticked by. A tight pressure welled in between Ari's legs, letting him know that his balls seemed to be getting in on the action happening up above them, as their weight twisted and shifted while seeming to become heavier. A guttural growl escaped from out of the college student's throat as he lowered his eyelids shut, the pressing need to spill his load from out of his now throbbing balls became a maddening need, the likes of which clouded all rational thought.

Or at least basic thought, as the more Ari stroked himself off the scent of growing arousal, thick and pungent as it was thanks to his body not having been dipped in the shower last night, sparked thoughts inside of his mind that seemed to focus on him finding someone to bury him his manhood deep inside of. Images of Juan quickly blossomed within his mind's eye, revealing the sight of the shorter blonde hispanic kneeling in front of him, thus making Ari growl harder. What he would have given to be able to get his clawed hands around the other; the thought of laying his classmate onto some freshly cut grass and then lifting his legs up so that his tender tailhole could be exposed to his pointed cock made shivers race throughout the raven haired youth's backside. Ari let out a whooping cry in order to call out his excitement as he imagined ramming himself deep into his crush's tight ass and then drilling the other with abandon. The mental image of the shorter male submitting himself to his sexual frenzy, crying out in wild glee while writhing oh so sexily underneath his sweat soaked, furry body drove Ari's hand all the quicker along his elongating shaft. 

"Juan. Mate. Good." Ari barked as ribbons of pre-come shot out across the toliet in front of him. 

The sound of the clear liquid hitting the water down below barely registered within the raven haired hispanic's lengthening ears, that was just how powerful his little fantasy was. He had always dreamt about the getting the other hispanic youth within his clutches and then claiming him for himself, yet the moment he was having right then and there was almost too much for him to bear, as could be seen by the fact that his entire body seemed to be convulsing as his muscular expanded his clothes to the point where the threads threatened to rip in certain places. Ari wobbled for a moment as his feet began to expand within his shoes, thus causing his balance to shift somewhat, in response to this he reached out to the padded wall in front of him to steady himself, thus dropping the plastic cup in his other hand. 

Ari's short tail wagged wildly within his pants as his hips gently swayed forward as if to mimic the thrusts happening within the hidden field within his mind. More groans and whoops escaped from out of the raven haired college student's tightening face as he drilled himself as deeply as he could into his crush's clenching anus. Ari would have given anything to be able to be able to lean down and wrap his incisors into the side of Juan's neck, thus placing two claims into the younger male's body, yet because the other wasn't there all he could do was pull his tongue back into his mouth and then grit his teeth together, all the while pumping at his deep red shaft hard enough to send his pelvis jackhammering forward fast enough to become almost a blur to anyone who might have been in the room with him. 

Ari finally fell over the edge of ecstasy when he reached down and then gripped the base of his shaft hard enough to make himself bark out loud like a dog whose knot had been caught on the inner rim of his mate's tailhole. Strong streams of yellowish cream poured out of the raven haired hispanic's slightly pointed cock tip as his balls pulled in deep into the underside of his body. The feeling of the pressure within being released was so sweet that Ari began to pant in relief as more and more of his semen splattered out over the bottom of the toilet seat and the inner rim of the bowl. The thick, musky scent of his climax quickly filled the inside of Ari's nose, making his tail wag all the harder inside of his pants. 

Ari slowly came down from his climax a couple of minutes after the tenth shot of his cum finally dribbled out from the head of his twitching shaft, tingles of cool pleasure traced a path down his spine making his toes curl within his shoes. It was upon uncurling them that the college student noticed how tight his shoes now felt, thus making him open his eyes in slight confusion. His black eyes widened when he finally took notice of the fact that not only were his shoes looking as though they were about to explode from off of his feet, given that the leather was actually ripped in certain areas. Confusion shocked the hispanic youth into jumping back away from the toilet, thus making him fall back onto the pads on the floor underneath him. 

Looking over himself, Ari noticed that not only were his arms much more hairy than they had been before, there were now many more spots littered all across his appendages. Lifting his shirt from his chest in order to see what the rest of himself looked like proved to be a mistake as his nails had hardened enough to the point where the tips tore the cotton material with a wince inducing ripping sound. Ari whimpered as he thought about having to purchase another shirt. That thought quickly brought him back to his current reality and thus made him begin cackling in frustration. Slapping a hand over his face, Ari was sadly introduced to his much longer canines as the tips of his fangs brushed against the skin of his palms. Pulling his hand back, the raven haired hispanic tried to control more budding laughter as it slipped out from his throat, yet it was hard to do as panic and uncertainty wrapped around his mind like a thorn covered vine.

A knock from behind him made Ari whip his head around. 

"Mr. Rodríguez, are you alright in there?" Someone asked, causing Ari to jump into the air. Once he came back down the raven haired youth quickly scrambled to stuff his half-hard erection back down into his pants, before going over to the sink to wash his hands. Once he cleaned his hands off on a nearby towel Ari went over to the door. 

Upon not finding a handle to unlock the metallic barrier he grunted in annoyance. "Mr. Rodríguez?" 

"Si?" Ari quickly shook his head to change his language. "Yes. I'm fine, but I can't find the handle to open the door." He said with a heavy spanish accent coloring his words.

When the door creaked open Ari took several steps back to allow whoever was on the other side to come in. The sight of an auburn haired woman wearing a white medical coat entering into the room immediately made the young hispanic's posture straighten. The woman seemed to notice this, as a smile tugged along the corners of her lips upon looking him over. 

"You don't have to be so nervous around me, I'm here to help you, not hurt you." The woman explained while smiling up at him.

"Y-yes ma'am!" Ari didn't know why he felt as he did in front of the other, but something in the back of his mind commanded him to make sure that he gave the woman the utmost respect imaginable. 

"I guess this should be expected, given how your changes are coming along." When Ari cocked an eyebrow at the woman she went on to explain, "From what I can see It seems that your changes are taking you along the Crocuta crocuta genus of mammals, or better known as spotted hyena, though according to the information collected by the medical personnel that brought you here it seems that there's some reptilian dna within your body. We'll need to get samples of your blood and urine in order to fully analyze exactly what's going on with you before we can say anything definite." The woman said with an air of sophistication which made Ari nod his head without meaning to. "With that said, have you filled up the cup that…" She began to say but then trailed off when her head turned towards the nearby toilet. 

"I'm sorry." Ari apologized before he could stop himself, his black eyes dipping down to the floor as he tried not to look at the female in front of him.

"It's quite alright." She reassured him. Turning her face back in his direction, she lifted up her hand to cough into her fist in order to reorientate himself before continuing to speak. "The medication that you were given has the side effect of boosting one's arousal, so your...sexual relief was to be expected, though am I slightly impressed by the volume of your release." Those words made a swell of pride build within Ari's chest. "With that said though, I'll need you to urinate into the cup on the floor and then hand it to me so that we can begin going over the tests we have prepared." 

"Yes ma'am." Ari didn't hesitate as he went over to do as commanded, the fact that the woman merely turned around to allow him to do his business wasn't missed on him. 

Once the raven haired hispanic finished up, zipping his crotch after once again stuffing his now completely pointed manhood into his pants, Ari returned to the medical worker's side. The woman nodded at the cup and then reached into one of the pockets on her coat to fish out a plastic bag. Holding it open and then letting Ari drop the sealed up container into the interior, she zipped up the bag and then placed it by her side. 

"Thank you for cooperating." Ari began panting after hearing her words of praise. "I know that this may seem somewhat confusing, or maybe somewhat entertaining for you personally, but please trust that we here at the research center are going to do everything we can to help you through your transition." She finished.

"Transition?" Ari cocked his head to the side while blinking.

"Yes." The woman opened her mouth to continue but quickly slapped her lips closed. "What were you told when you were brought here?" Her eyes became hard upon asking this question.

"Nada en realidad." He admitted honestly before realizing that he spoke his native language once again. "I mean, not really, just that I should try and stay calm and to do everything asked of me." 

"Of course." The woman sighed before shaking her head. "Well, to keep it simple, you're here inside of a military research facility because you were given an experimental drug that shouldn't exist. We're going to have to keep you here in order to monitor how the drug in question will affect you, both physically and psychologically, seeing as it can have some very...interesting effects on certain people." 

Ari wanted to ask about the drug he had been given but a look from the auburn haired woman told him that he really shouldn't. "I understand. How long am I going to have to stay here?" Ari was sure that Gaurav had gone to speak with grandmother by now, as the tiger was nothing if not dedicated in doing what was needed of him, especially in a situation such as this, he just hoped that the striped feline would be able to remain patient with the older woman as her understanding of english was not the best. 

"At the moment, I would say at least a month, maybe two." The woman answered honestly. Ari whimpered at that. "I'm sorry, but it's really going to be touch and go with your stay here, as the drugs in question may do a number of things to your body and mind that we're not prepared for."

"I see." Ari wanted to ask more questions but he chose not to, mostly because he didn't want to possibly make this situation anymore complicated than it needed to be at the moment by learning information he really didn't want to. "Gracias." He grunted and opened his mouth to correct him but was cut off when the medical worked replied with, 

"De nada." She then turned to leave him alone in the room after beating on the door and having it open by a man dressed in military fatigues. 

Once she was gone and the door was closed Ari paced around his room for several minutes, sniffing and huffing at the four corners of the padded interior, before moving onto the only bed within the area. Flopping down onto the mattress, Ari found himself rolling around like a feral beast as he couldn't find a comfortable position to lay in before he got the bright idea to take his clothes off. Slowly pulling himself out of the tight material, Ari let out a sigh of relief once the cotton material came free from his body, though it was in taking his shoes off that got him the most relief, as his feet, which had increased to three extra inches in length, flexed against the cotton sheets underneath his hairy form for several seconds before settling down. 

Ari reached his hands down the side of his body to feel himself over, he soon began to marvel at how dense the hairs along his body had become in just a short while, though he found himself becoming curious as he felt hard slabs of skin pressing out against his body. Scratching over the areas in question made his right leg kick out underneath his body in a rather pleasurable manner, something for which the raven haired youth was somewhat embarrassed by. After he finally had enough of rubbing himself over, Ari reached back behind himself to feel over his tail, as he had yet to truly take stock of the fact that his spinal cord was growing further across the cleft of his muscular rump. 

The feeling of the short appendage wagging across the tips of his fingers was bizarre to say the least, and yet Ari found himself quickly growing accustomed to the new appendage as he stroked along its furless length. If he had to guess, Ari would have assumed that he had almost half a foot of tail streaming out of his backside, the idea that his new anatomy would soon grow larger and longer made a small smirk cross the young hispanic's lips. He drifted off to sleep thinking about himself having a long tail whipping across the side of his legs, not at all aware that his breed of hyena had rather short tails. 

Ari came to find this information out in the weeks to come as he went along with several others to take various physical tests for the research staff at the facility. Being able to work out in the gym was the best part for the young hispanic, as he found himself able to bench press more iron than he had before, not to mention jog much longer than he normally would have been able to while on the treadmill. Getting his blood taken was not somewhat that Ari found to be all that pleasant though, as he had never been all that fond of needles, though thankfully the people who took the crimson fluid from him were able to do so quickly enough, despite him bearing his fangs at them on more than one occasion. Thankfully for everyone involved he was fed some pretty good food, so that helped to alleviate his rising temper, Ari was also able to call and check on his grandmother every couple of days, something he was eternally grateful for, as the older woman had become somewhat worried upon not being able to see him; her comments about the talking tiger she had sent to their home got a few chuckles out of him, if only because she still couldn't wrap her head around the ideas of anthromorphs existing thanks to her spotty memory and somewhat isolated upbringing. Ari had no idea what she would think about him once he left the facility, though he had been assured that things would work out when he brought his concerns up to the auburn haired researcher who was basically his personal case manager. 

The woman, whose name was Ariel Sullivan, was kind enough to answer a number of questions Ari had about why the drug he had been given was made and how it was able to escape from the facility in question - both answers coming in the form of their creator bringing them to life in order to give those who wanted to become anthromorphs the opportunity to become as such - something that his superiors had thought to be a good idea at the time, given that naturally born anthromorphs were notorious for not wanting to become part of militarized conflicts, however the scientist in question proved himself to be a little more...extreme in his desires and so had spread a bunch of the drugs around the countryside before disappearing, apparently the search was still ongoing for the man.

Ari didn't think too much about this as the days passed into weeks and his changes became all the more prominent throughout his body. The feeling of his deep red fur growing out all across his body was something that Ari found to be beyond strange, as he constantly felt an itching buzz surrounding him almost all the time, couple that with the odd sensation of his body growing outwards as his bones shifted beneath his skin to give way to his growing internal organs and the young hispanic was almost always in a constant state of discomfort. Thankfully the changes proved themselves to be rather painless overall, something that others couldn't exactly say, though it was beyond strange to feel his skin pushing outwards during the evening as his cobra hood made its way forward along his backside. Everyone was completely baffled by the fact that Ari was growing such a piece of anatomy, as no one had seen both mammalian and serpentine growths encompassing those who had been administered the transformative drug before. A sense of excitement encompassed many of the researchers as they poked and prodded at him in order to see just how far his changes would go, something that Ari always hissed about whenever samples of his scales and red spotted fur were taken.

As the weeks rolled by into months the changes began to slow down, thus leaving Ari with thick serpentine hands and feet, black spots dotting his shaggy crimson fur, and a massive serpentine tail snaking out along the back of his now eight foot tall form. The change in height had been somewhat jarring to have to deal with, as Ari was forced to duck down everywhere he went in order to keep his head from banging into anything, but thankfully enough once he got into an area beyond the various entryways he could stand up easily enough, though fitting himself on his tiny bed had become an impossibility during his time at the facility, thus forcing the staff there to get him a large mattress to sleep on. Ari didn't mind this, as he had slept on much harder back home when he had been a pup...child. 

Ari growled as he thought about having to correct himself once again; he had been struggling with his thoughts more and more as time went on, something that the Ariel had warned him that he would end up doing, but it was still annoying as all fuck to have to think in human terms when speaking with someone. Luckily enough his handlers were able to deal with his out of place words not to mention his animalistic vocalizations whenever they spoke with him during the times when they brought him into the examination room that smelled too much like disinfectants for his now much more sensitive nose. Ari pushed those thoughts away as he paced around his den, he was going to get a chance to go out and meet with the others who had been transformed today, he had been somewhat starved for companionship despite him calling both his grandmother and Gaurav to check on the both of them. Ari made a mental note to go and thank the tiger for looking over his grandmother for him once he was released from the facility, as he owned the striped feline a lot for looking after the older female. 

"Ari?" Ariel called out from behind the door. The spotted hyena made a low whooping nose upon hearing the researcher's voice calling out to him. "May I come in?" 

Ari made more whooping noises before shaking his head. "Y-yes." When the door slowly opened Ari ducked down low so as not to startle the female, he had scented her nervousness around him, which was expected given their three feet difference in height and his predatory nature. He would of course never hurt her, not after how good she had been to him all these months, but sometimes that was so hard to convey with words, thus why he always kept his cobra hood tucked tightly against the side of his head and his tail curled around his leg. 

"How are you doing today?" Ariel asked as she entered the room. 

"I'm good." Ari panted while flicking his rounded ears on top of his head.

"That's good to hear." She chuckled. "Are you ready to head out into the yard?" 

Ari nodded rapidly before grunting and answering the question. "Yes ma'am." 

"Then let's hurry on." She stated before turning her back to him. 

Following after Ariel, Ari all but pranced as he walked beside the smaller human. The guards watching him got a few good snickers out of seeing him act so puppish, however he didn't bother to pay them any notice save for keeping an eye on where their weapons were holstered onto the side of their hips. Ari had heard that there had been a few incidents from some of the others within the facility, one such incident which ended with a life being lost. The spotted tried not to think about this, as he had always kept full control over himself, though he was worried about Ariel, as the female was responsible for him, thus he made sure not to do anything which might put her rank in danger with her superiors, who she often commented on with a rather tense tone lining her voice. 

Ari wanted to lean down and lick the woman's face in order to calm her whenever she spoke of her superiors, but upon him doing so the first time he had been reprimanded for such a gesture of affection, much to his chagrin. He mentally sighed as he thought about how annoying it was that humans didn't like to show such affection, but it was understandable that they chose to be so reserved, what with the limited show of affection they shared amongst their kind. By the time the two of them went out into the yard Ari found himself looking over almost three dozen anthromorphs all ambling about in various states of dress. He personally didn't bother wearing clothes, since his fur protected him well enough from the elements, plus he didn't really see a reason to be ashamed of his lower anatomy, what with his twin penises being housed deep within his body where they belonged. Growing a second penis had been rather strange for Ari, as the splitting of his flesh was not a sensation that he would wish on too many creatures, however the extra stalk of flesh was a lot of fun to run both his fingers and tongue across, especially when he caught the scent of male arousal, not his own, seeping into his nose. 

"How do you feel?" Ariel asked, jarring the hyena out of his mental daze.

"Estoy bien." He answered without thought before looking down at the smaller female. 

"That's good to know." She returned. "Do you see anyone that you want to go and speak with?" 

Turning his head to look about the throng of other anthromorphs, Ari looked the lot of them over for several seconds before shaking his head. Turning down to the smaller woman, he was about to tell her that he didn't when his head shot up to do a double take. His black eyes hovered over one creature, a muscular looking saber toothed tiger who was tapping away on a cellphone, for several seconds before his legs found themselves moving on their own accord. Ari thought that he heard Ariel calling out to him but he couldn't be sure as his focus was solely on the male - he could smell the intoxicating scent of the masucline figure from where he had been standing making his serpentine tail snap sharply behind his back - thus leading him over to the other. It was only once his larger body overshadowed the plain coated feline that he stopped in his tracks. 

"Juan?" Ari called out, making the long toothed feline jerk and then flip his head up.

Brown eyes stared at the much larger male for several seconds before a small smile tugged at the edges of the feline's lips. "Hey Ari, nice to see that I was right about you being here." The other hispanic chuckled.

For a moment Ari couldn't think to say anything to his former classmate, his mind was simply in a complete whirl over the fact that the other was here, however his body decided to once again move without his command, thus leading him to reaching out to enfold the smaller male within his arms. Juan didn't protest as he was dragged forward and then up so that the two of them stood face to face with one another. A moment of silence followed with Ari leaning forward and then pressing his snout into the saber toothed tiger's muzzle. Juan didn't think to complain, as he knew what was about to happen, he simply opened his mouth and interlocked himself with his mate in an epic tongue battle. 

The pair quickly became drunk on one another's distinct flavor, thus leaving them to purr and growl in pleasure as they stared each other in the eyes. 

It was only once the pair separated for air that Ari hefted the smaller anthromorph up into his arms and then spun around to take him back to his room, completely forgetting about his want to spend time outside of the stuffy interior. The fact that Juan didn't bother to complain, and instead actually nuzzled his boxy head into the larger male's chest in an obvious show of comfort, made Ari's heart leap for joy inside of his chest. The pair didn't notice the guards trailing after them as the hyena returned inside of the building and then finally his room, the only the pair knew was that they had been separated too long and thus needed to reaffirm their place between one another by rolling in each other's scent. The fact that Ari's cocks were pushing out of the slit in between his legs at the same moment that Juan's single dick rose free from his sheath only served to tell the other male that they would be mating before long. 

- - - - -

Upon getting to his room Ari gently placed the saber toothed tiger down onto his mattress and then took a step back to watch the other. Juan chuckled as he looked up at the larger male, he then set his phone aside on the floor and leisurely stripped himself out of the t-shirt and sagging pair of pants wrapped around his waist. The spotted hyena couldn't help liking his fangs as he watched his soon-to-be mate revealing his golden furred stomach to him, while at the same time he exposed his thick thighs and plump sheath to the taller anthromorph. Once the other hispanic was fully nude Ari stepped up to the long toothed feline and then onto him. Juan was completely shocked by this, as he hadn't expected such a thing to happen, however a growl from the dominant male made him cease trying to squirm from underneath Ari's soles. Once it was clear that the other hispanic youth wasn't going to try and move from out of his proper place underneath him, the spotted hyena began to roll his massive foot along his crush's sheath.

Ari watched in endless amusement as Juan shuddered from the sensation of having his most intimate area toyed with in such an unfamiliar manner. The scent of the younger male's musk grew in intensity the more Ari stroked his padded heel along the length of Juan's cock, much to the spotted hyena's amusement. The sensation of wetness blooming along the bottom of his foot made the elder anthromorph sweep his serpentine tail back behind his scaly back in quickfire motions; he had been somewhat concerned that his little mate might not be receptive to such a touch, but that was proving to be a false assessment given the hazy look of contentment which draped itself along the other's short muzzle. 

Moving his foot with greater intensity, Ari made sure to stroke Juan to complete hardness before moving his toes down to massage the head of the smaller male's pointed cock. Looking down at him, the spotted hyena studied the barbed cock within his grasp and then marveled at its size and shape. While not as big as his, Juan possessed a pillar of pink colored flesh that was respective for his size and stature. Down below, the saber tooth tiger's balls twitched just as a clear glob of liquid musk poured out of the head of the smaller male's dick. Using the dollop of liquid to coat his toes in Juan's scent, Ari dragged his foot up the side of his mate's muzzle, forcing him to breath in the intoxicating odor which had driven him to many an orgasm back when they attended college. 

Juan didn't resist when his lips were pried open, he simply obeyed the silent will of the more dominant male. The feeling of the golden furred feline's warm tongue coiling around the head of his big toe made shudders creep up the side of Ari's spine, and yet that feeling was nothing compared to the sensation of the submissive anthromorph reaching out and taking his wiggling foot within his demure hands. Ari let out a low whooping howl as he Juan began to knead his fingers, his muzzle then parted like a curtain being drawn up when the long toothed feline slowly began to kiss his sole in time with his licking. In between his thighs Ari's cocks had long since hardened to their full length, thus small streams of his own pre-come shot out onto both Juan and his sleeping mattress. 

Seeing this Juan dug his fingers even harder into the spotted hyena's foot, teasing him as he did so with cute little strokes of his tongue. It didn't take too long before these twin sensations sent Ari's animalistic overdrive, thus after his toes were completely soaked with saliva the spotted hyena pulled back and pounced on the now chuckling sabertooth. Juan didn't resist his mate's affections as the other wrestled him around onto the pre-come stained mattress, in actuality he seemed to relish in the dominance that the larger hispanic was showing, as could be seen by how he arched his backside in an obvious show of acceptance of his place between the two of them. Juan let out a happy huffing to show his appreciation of the younger male accepting his place in between them. 

Once he was kneeling over the shuddering feline, Ari placed both of his cocks at the center of Juan's puckering tailhole and then pressed forward. He immediately stopped when the smaller anthromorph let out a yowling cry of pain. Tipping his head down to look at his mate, Ari quickly came to the realization that the other wasn't ready to take both of his leaking shafts into himself, which made sense, given that the other had been an anal virgin not more than a few months ago, given his previous sexuality. With that thought in mind the spotted hyena pulled himself back from his kneeling position until his blunt muzzle was set squarely in between the firm cheeks of the sabertooth's rump. Looking over the tight pink pucker set in between golden fur, Ari gave the wrinkled muscles a quick sniff and then slapped his thin tongue along the center of his mate's butt. 

Juan let out a booming cry at the feeling of having his ass suddenly licked, much to Ari's smug delight. 

Curling his tongue faster and faster along the winking ring of flesh, the spotted hyena worked quickly and diligently to make the long toothed feline's body ready for what he would soon be introducing into it. That Juan squirmed around in unabashed pleasure only served to tell Ari how good a job he was doing at showing the younger male how good the pleasure of male-on-male sex could be, thus making his ears twitch in excitement for what was to come; the feeling of the golden furred feline's tail beating against the top of his head made Juan chuckle as he continued doing the task set before him, not that Juan could summon the strength to care about such a thing. 
Burying his nose as deep as he could into the smaller anthromorph's backside, the spotted hyena breathed in more of Juan's heady scent as he slipped his tongue deeper into the other. It was when the sabertooth suddenly jumped up against him that Ari realized that he had found the younger male's prostate. He swiftly attacked the bundle of nerves inside of his mate's body, whipping them into submission and thus causing Juan to scratch at the mattress beneath him before lifting his head up to let out a growl of wanton need. 

After a few minutes of making sure that the other's insides were liberally coated with saliva Ari pulled back to inspect his handiwork. As expected the sabertooth's tailhole shone like a winking star underneath the low halogen lights shining above both of their heads. Nodding in satisfaction, the spotted hyena once again crawled over the younger male's backside. Setting himself into mounting position once again, Ari leaned down to nuzzle his mate's throat, getting a half dazed lick from him in return, and then gently slipped his lower cock into the tight tunnel set underneath him. Juan hissed but didn't verbally protest as his anal virginity was fully taken by the larger anthromorph, something for which made the spotted hyena breath out a sigh of relief. It took a full minute before he was fully seated inside of the younger male, once he was though Ari allowed his kitten the time needed to adjust to his girth before slowly pulling back in preparation to fuck the other.

The first thrust into the sabertooth was met with a loud growl of surprise, however the second found Ari letting out a grumbling purr of pleasure as he wiggled himself around underneath his mate's bulk. Seeing that the other was in no pain, Juan carefully bucked his hips back and forth into the younger male's ass, slapping at his taut rump with careful, yet audible strokes of pelvis as he did so. The strength and speed of his thrusts quickly began to grow as the seconds ticked into minutes, thus allowing Ari to fully consummate the relationship he had just begun with the younger anthromorph. The feeling of his low hanging balls slapping into the bottom of Juan's body made sharp shocks of pleasure curl throughout the spotted hyena's belly, he was finally doing what he had always dreamt and yet the reality of such a happening was so potent that Ari found himself almost drifting outside of his body as he continued to jack hammer himself inside of the smaller feline.

Juan let out a yowl of appreciation for his new position in between the two of them as surrendered to his friend's restless domination of his body and some of his mind; the longtooth feline didn't quite have the words to describe what was happening within his head, but with every thrust that jammed its way throughout his interior he found himself unable to think about anything more than allowing the spotted hyena to take full control of his body. His thought soon became fully consumed with surrendering himself both body and soul to Ari as harsh huffs of air escaped from out of his now burning body.

Ari couldn't exactly explain what he was feeling as he sensed more and more of his mate's surrender, however as Juan grew more submissive to his physical control over his body the spotted hyena found himself growing all the more possessive and protective over the younger male. Leaning himself down along the sabertooth's body, Ari sunk his fangs deep into the side of Juan's shoulder, claiming the other male with a fierce bite that would scar over in the days to come. Juan was his now, and he moved heaven and earth to protect him from anyone stupid enough to think to try and take his mate from. Pumping his hips forward with harder strokes, Ari set his mind to fully staining the younger male with the proof of his claim, something for which the long toothed feline readily accepted as he relaxed his muscles as much as he could for his mate. 

It took several more minutes of pounding Ari's ass into putty before Juan locked his fangs even tighter around the younger anthromorph's shoulder and then spilled his load deep inside of the sabertooth's rump. The sensation of the spotted hyena's hot warmth drenching itself deep inside of his guts sent a white trail of passion surging through Juan's body, thus forcing him to throw his head up as best he could to sound off his coming orgasm. The potent sense of semen raining out from both of their bodies coated the air in a heavy, pungent musk the likes of which followed the sounds of wet splatters hitting the mattress as Juan spent himself on the mattress down below.

Their shared climax lasted about several minutes before fully tapering itself off. After doing so Juan slumped down onto the bed, thus inadvertently pulling himself free from his mate's cock. The feeling of cum cooling on his backside made the sabertooth chuckle as he slowly rolled himself over so that he could look up at the still kneeling spotted hyena. Looking up into Ari's slightly clenched eyes, Juan reached up to drag the larger male down onto him, something he slightly regretted when the full weight of the other's bulk dropped onto him. 

"Pesada." Juan chuckled as Ari attempted to try and maneuver himself into a less cumbersome position, the long toothed feline refused to allow the other to do so, instead curling his legs up and around his mate's backside, thus locking him into place. "¿Te divertiste?" Ari asked as he slowly began to clean the spotted hyena's face with his tongue.

"Si." Ari nodded as before letting out a happy whooping call. "Gracias, Juan." 

"Fue un placer. Literalmente." The smaller male chuckled. 

Nothing more was said between the pair as they rested from their explosive climax, their steadily beating hearts saying everything that needed to be said at this moment. The pair would never be able to say when they drifted off to sleep, however the researcher's watching them from the various hidden camera watched everything with rapt fascination as many of them began to debate amongst themselves about what they had just witnessed and the merits of such a revelation, not their either Ari or Juan were in a position to care.
