"¿Esto es en serio?" Ari asked before shaking his head. "I mean, is this for real?" He asked Gaurav as the tiger stood in front of him while leaning against the side of the college building. It was late in the afternoon and wrestling practice had just ended, so there was no one around to inquire as to why the two students were still there when everyone else had vacated the premises. 

"Yep." The striped feline nodded. "I was really surprised when Professor Issac passed this pamphlet onto me, but whatever I guess." The tiger chuckled.

"I suppose so. Anyway, are you going to take part in this?" The hispanic youth asked while looking over the paper clutched securely within his hand.

"Nah, I'm already focused enough as is on trying to get inside of your tight little butt," The tiger snickered before snaking his way behind Ari's back. The raven haired youth yelped when a firm groin and a pair of hands pressed deeply into his rump. "I don't need anything else to help me try and pry you open." 

"Hijo de puta!!" Ari growled before elbowing the striped feline in the stomach. "I told you about that!" 

Gaurav grunted before reaching down to rub at his now injured belly. "Can't fault a guy for trying, right?" The tiger winked, making Ari roll his eyes. "Besides, you should be showing me some appreciation, since I talked a certain blonde into taking part in this medical trial thing."

"Really?" The thought of being in the same situation with Juan made Ari's heart literally dance within his chest.

"Yep." The tiger nodded. "This is what happens when you have a charming and handsome cat like me at your back." Gaurav growled into Ari's ear at the same time he began to grind his crotch forward. The striped feline would have said more but a firm hand reached around his crotch. 

"One more word and I tear it off." Ari threatened while still reading over the pamphlet. 

Knowing that his friend could indeed do such a thing, Gaurav lifted his hands up in surrender. "Alright! Alright! Let's not do anything crazy now." Ari chuckled as he felt the tiger move away from him. When the other returned to standing in front of him the hispanic youth looked up at the striped feline with twinkling brown eyes.

Gaurav merely grunted in return.

When Friday rolled around Ari found himself walking into the medical center where the focus study written onto the pamphlet would be taking place. Looking around didn't reveal anything all that interesting about the white tiled building, however after gazing over to his right the raven haired youth watched as Juan made his way out of the nearby bathroom. Without thought, Ari eased his way over to the other hispanic, his crotch throbbing with just as much excitement as his heart at the sight of the blonde.

"Juan." Ari called out, making the blonde's head whip in his direction.

¿Cómo estás hoy?" Ari asked while reaching out to hug the other. 

"Estoy bien." Juan returned the hug without question. "¿Cómo estás?"

The two college students chatted up for a few minutes before they made their way to the front desk to submit their names for the focus trial. It took about half an hour for all of their personal data to be collected and then for them to be taken for the manadtory physical, yet once this was done the pair were taken to individual rooms by a medical worker and then given a spiel about the drug they would be taking and any possible side effects that may result before having the chemicals in question injected into their arms. Once this was done they were brought back out into the lobby area and given their payment for this part of the trial. 

Heading out of the building, Ari noticed that two other youths were brought forward to repeat the process, though he paid the others little attention as he eased himself into Juan's personal space. Without thinking about it, the raven haired hispanic began sniffing at the back of Juan's head as nonchalantly as he could. The soft scent of sandalwood and lemongrass prevaded his senses, making Ari moan with growing need. Hearing this, Juan turned to look at the other with a raised eyebrow. Ari immediately turned his head to dramatically sneeze before shaking his head and then asking the blonde what he would be doing for the rest of the day.

"¿Qué vas a hacer más tarde?" He inquired while fighting back the urge to take Juan's hand into his own.

"Me voy a casa. ¿Qué hay de tí?" Juan asked as they made their way down the street to the bus stop.

"No estoy seguro." Ari knew that his grandmother wouldn't be doing all that much today besides watching her soap operas, something he just couldn't get into, and because he didn't have work there was nothing that really could occupy his time for today besides doing some weightlifting at the local gym. 

"¿Quieres venir a mi casa?" Juan asked.

"SI!!" Ari answered, nearly jumping up to punch the air as he did so.

Juan simply smiled back at him. 

The two chatted some more as they waited for the bus to arrive, not about anything important but enough to fill the void between them. Ari found himself slightly scratching at his arm during this time as he felt a slight burning run throughout his veins. Nervousness would have erupted within his heart over this happening had he not been told that such an experience would have been a slight side effect from the drug now running throughout his system. It was just as the scratching was starting to feel good enough to make him roll his tongue out from his mouth that Juan reached out to block his hand. Ari blushed as he looked to the blonde with a questioning gaze. Juan said nothing over his action, instead he simply shook his head at the taller hispanic. 

The ride down through the city was filled with more conversation, but that quickly died down after the two exited the bus at Juan's command. Ari, in stunned amazement, found himself gobsmacked as the two of them walked through the nice looking neighborhood across an old pair of train tracks to a group of houses gated off from the rest of the world by decorative looking metal fences. When Juan took them up the hill of one particular house after buzzing the intercom, the raven haired college student couldn't help but whistle at the pristine looking garden which stood out around him. 

"No sabía que eras rica." Ari chuckled somewhat nervously, to which Juan merely waved his hand back at.

By the time the pair got to the front of the mansion which stood up upon the hill Juan turned to look back at his fellow classmate with a somewhat annoyed expression tugging at his face. 

"So, I know this may sound weird, but try and speak english while inside the house, si?" 
"Ok, but why?" Ari was slightly confused over this, as he couldn't figure out why they would suddenly switch from using their native language to the foreign one they had been forced to learn as children.

"Ma wants everyone in the house to be 'cultured' like our neighbors or something," Juan blew a lock of golden hair out of his face to show his annoyance over the rule. "I think she just wants to look...how do you say...falsa to her friends, but I don't care. I just don't want to hear here yell at me again." The blonde sighed.

Ari acted in response to this expression of annoyance by reaching out and hugging his classmate as tight as he could. "I understand. I'll do anything to make you...ugh, make things easy on you." 

"Thanks." Juan replied while patting the other on the back.

Ari would have given anything to kiss the other right then. He didn't though, instead he pulled back and then waited for Juan to let them into the house. They were immediately met by a short, brown haired hispanic woman carrying a cell phone against her ear.

The conversation with the woman, who turned out to be Juan's mother, proved to be very short and sweet, as she greeted him with all the air of an actor performing on stage, something which completely weirded the raven haired youth out. Ari was able to catch himself from saying anything foolish as Juan quickly shepherded the two of them up to his room before his mother could ask any questions that would have made the blonde want to bury himself into the ground outside. Two of his younger siblings raced past them on their way to the mall; a quick wave was the only sign of greeting either of the elder boys received in response to Juan calling out to them. Once inside of his room, Juan swiftly shut the door and then flipped the lock. 

He then subsequently unflipped it with a grimace.

"Is something wrong?" Ari inquired while looking the other youth over.

"The last time I locked my door ma knocked on it just as I was ploughing into my ex-girlfriend." Juan shook his head with a sigh. "That was a nightmare to have to explain, especially given how much trouble it was to bring Cindy up here." Had Juan turned around at that moment he would have seen the dark scowl which covered Ari's face like a stormcloud, thankfully he didn't and instead kept talking. "That's one of the reasons we had to break up, as ma was not going to let me keep seeing a puta without her permission." The blonde snorted.

Several words wanted to come out of Ari's mouth at that moment but he held them all back just in time to see Juan turn around to look at him. 

"Anyway, you probably don't care about my love life, so why don't we find something to do instead." Ari wanted to protest this statement but didn't in favor of turning around to look about the room.

As expected of such an opulent home, Juan had everything that one could expect within his room; a large four poster bed stood against the back of the bright purple wall, while a massive entertainment center complete with every electronic gaming system that was currently out on the market stood before it. The nearby balcony stood open revealing the waning light of the afternoon sun to the world at the same time the black wood ceiling fan swung in lazy circles up above. Movement caught Ari's eyes making him turn just in time to see Juan stripping his shirt from off of his upper body. The raven haired youth felt his pulse race as he looked over the tanned skin which glittered somewhat within the vermillion light streaming through the open windows. Eagerness made Ari move out to Juan, however before he could reach out to slide his hands down the side of the younger college student's lithe frame Juan turned to look at him.

"Do you want to play one of the games I have or watch something on tv?" Juan asked, completely oblivious to what Ari had planned.

It took the raven haired youth a moment to come back to reality, the silent whisper in the back of his head urging him to tackle the blonde onto his bed berating him for resisting its command, but once he did he turned away from Juan to look at his gaming station. Upon seeing one of the gaming stations his inner geek slowly crept up, a few minutes later both Juan and Ari were whooping and hollering like fools as they watched their two player avatars fight through a horde of blood orcs on a raining battlefield in the middle of a broken war camp. Ari didn't think about anything else as he used his character to cut through two charging orcs with his long sword, which was covered in lighting runes, something that was both good and bad at the same time, given that the burning had returned to his arm and his body was slowly inching its way closer to where Juan was sitting on the bed next to him. 

It was only after the current war campaign had come to an end that the raven haired hispanic noticed both, he growled as his arm felt as though it were on fire at this point, yet in looking down at his muscular limb he noticed that a dark red spot had blossomed onto his arm. For a moment he thought about calling the number the medical center gave him in order to report this, but he then thought about the money he was getting for this study and decided against it. Instead he slapped a hand over the spot in a vain hope that it would just vanish like a mosquito if he did so.

"Are you alright?" Juan asked as he turned to blink rather owlishly at Ari.

"Yeah, I just…" Ari licked his lips when he noticed how close the blonde's face was to his own. The smell of the other hispanic youth's breath, minty and sweet as it was from whatever toothpaste he had used this morning, made Ari lean forward without meaning to.

Juan froze at the same time Ari did. 

Neither chose to move from where they were seated, the touch of their lips against one hummed like an electric current drawing the two of them together. Brown eyes met jet black eyes in silent tandem, neither of their owners knowing exactly what to do at the moment. 

A knock at the door made Ari pull back. 

The raven haired youth said nothing as he picked himself up from the bed and then hauled ass out of the room. Juan's younger sister barely had time to get out of the way before Ari flew out of the room towards the front door. Juan said nothing, he simply looked down at himself in slightly bewilderment. 

Ari put himself on complete autopilot as he made his way down the gardens and out of the front gates. He only came back to himself when he threw himself inside of his apartment, and that was only because his grandmother called out to him, thus shaking him free of the panic which had eclipsed his thoughts. 

"¿Estás bien, nieto?" The elderly woman inquired as she came over to look at Ari.

Ari could only shakily nod his head in response to her question.

For the rest of the weekend Ari did everything he could think to try and put what had happened out of his mind; waking up and then heading to the local gym Ari brutalized his favorite punching bag before lifting two hundred pounds of iron with surprising ease before he went inside of the sauna to try and sweat out his growing frustration with the burning feeling within his arm. Taking a swim after washing down inside of the showers, Ari returned to punching at the sand filled bag before moving to one of the nearby stack machines. He continued with his overly exertive workout, completely unconcerned by the fact that he was straining his body more than he usually did, until it was time for him to go to work. Making a quick stop at home to both get his workout uniform and make sure his grandmother ate her dinner, Ari jogged to the local bar instead of taking the bus, thus meaning that he was a sweat soaked mess by the time he got to work. Thankfully his boss, a chubby human who had a cigar permanently perched in between his thick lips didn't have much to say to him about it, as there was already a fight going on between two angry looking hispanics dressed in ripped and faded jeans. 

Not feeling like dealing with any stupidity right then, Ari went over and grabbed the two by the arms, twisted them in such a way that both yelled out in frustration at being manhandled in such an uncomfortable yet painless manner, before tossing them out onto the street. The few clubbers who were sipping away at their drinks cheered when Ari returned into the bar, making the raven haired youth pause and then blink. Once he realized what he had just done, and how effortlessly he had done it, Ari puffed his chest rather proudly at the praise he received. Thankfully the rest of the evening proved to be less exciting than earlier in the evening, thus leaving Ari to stand around and think about what he was going to say to Juan when he saw the other in class on Monday. 

A frustrated hiss escaped out of the young hispanic's mouth as he could just imagine what his crush would think when they met up once again. By the time it was time to close up the bar Ari guts were wound tight with anxiety. Getting paid helped him to alleviate some of his worry, as he would be able to pay off the light bill which was already due, though not quite so much. Sleep helped to calm down much of his nerves, but not so much the burning that once again ran throughout his arm. Kicking within his sleep, Ari never noticed how the area on his arm darkened into a blood red mark that looked almost like a spot. It quickly became covered in a thick mound of hair, something that Ari just barely noticed when he woke up several hours later to get himself ready for school.

By the time he made it to his first class Ari had mostly forgotten about the new oddity that had rested underneath his shirt sleeve, mostly because he was more focused on what he would say to Juan once he saw the other hispanic youth. The entire day was mostly filled with worry for the raven haired college student, however when lunch rolled around Ari found himself having something more to worry about after Gaurav pulled him out of the cafeteria. 

"¿Qué estás haciendo?" He growled as the tiger hauled him into the bathroom. 

"Let me see your arm." The tiger ordered while trying to lift up Ari's sleeve.

"Why?" Ari snatched his limb back just as Gaurav's yellow eyes noticed the furry spot on his bicep.

"Because that's not supposed to be there, that's why." The striped feline hissed while reaching up to stroke a hand across his head.

"Huh?" The raven haired hispanic asked before he turned to look at his arm. "It's just a weird rash or something from the shot I got. It's nothing to worry about." He finished dismissively.

"Yeah right." Gaurav grunted. "You do know that there are rumors flying around that some of the students who got this shot have been hospitalized, right?" 

Ari blinked. "No." 

"Yeah, well they are." Gaurav scowled. "Have you spoken with Juan today?" 

"Not yet." Ari hung his head at the thought of the other hispanic.

"You might want to, because if this," The tiger pointed at Ari's shoulder before continuing. "Gets worse, then you and he might end up sharing a hospital bed next to each other."

Ari would never admit that said thought aroused him. "Right." He turned away from Gaurav to the mirror in front of him. It was on inspection that he noticed that his teeth looked a little bit longer than they had earlier this morning. Licking over the slightly elongated fangs Ari yelped when a sharp pain crept along his back.

"What's the matter?!" Gaurav asked, visibly alarmed. 

Ari would have answered, but at the moment his body felt as though it was surging with the kind of tension which only came from a strenuous workout. Gripping the sides of the metal sink in front of him, the black haired hispanic let out a low, animalistic groan as pressure along his backside flared wildly. The sound of squealing metal made Gaurav take a step back in fear, yet upon seeing Ari's hand spread wide and then clench deep into the sink harder enough to forcibly bend it his muzzle dropped in surprise. 

"Blessed Shiva…!!" The tiger whispered as he watched Ari writhe in front of him for several seconds, his back seeming to actually ripple while movement in his pants arrested his attention south, before the raven haired hispanic grunted and laughed loud enough to make his fur stand on end.

It was only when Ari quieted back down that Gaurav went over to his friend's side to check on him.

"Are you alright?" The striped feline then cursed himself. "Of course you're not." Gaurav shook his head. 

"¿Puedes revisar mis pantalones?" Ari asked while slowly breathing in and out in order to calm his quivering heart. 

"I did not understand that." The tiger grunted in annoyance, his golden eyes swiftly turned to the door to make sure that no one was about to stumble in there.

"Can you check my pants?" Ari hesitantly asked, he tightly clenched his eyes in hope that the worst hadn't come to be as he felt something moving inside of his pants.

"Uhh, sure." Gaurav replied. 

He slowly moved his hands around the side of the raven haired hispanic's pants, unfastening his belt. Once the offending leather was loosened the tiger carefully slipped Ari's pants down. Since the other wasn't wearing any underwear Gaurav's eyes were presented with a sight that he was not expecting to see, one in which made his face twist up.

"You have a tail?" The statement couldn't help being a question, as the sheer disbelief at seeing the small appendage swaying back and forth behind his friend's backside completely baffled the tiger. 

"¿HUH?!" Ari immediately flipped his head around to try and see what the striped feline was talking about. His black eyes widened to an impossible degree as he looked to the flesh covered strip of bone which pushed against his backside. "¡¿Qué diablos?!" He yelped in clear fright.

"I agree, even though I have no idea what you just said." Gaurav chuckled as rising panic began to creep within his voice. "We've got to get you to the medical center, like yesterday." 

"Juan." Ari said without thought. "Did the same thing happen to Juan?" 

"I wouldn't know, but I also don't really care." The tiger grunted as he helped the human, or rather transforming human, lift his pants back up onto his rump. 

"I should go and see him." He whispered out loud.

"You need to get yourself checked out rather than worrying about him." The striped feline hissed in clear annoyance.

Ari growled back at the tiger, his lips fluttered up from over his elongated fangs as drool dripped over their growing lengths. Not wanting to allow the other male to so easily dominate him, Gaurav growled back, lowering his ears and revealing his own fangs in a clear show of being ready to fight if the other pressed the issue. Time seemed to stop as both men glared at each other, black and golden eyes shimmered with the heated need to be 'right' in this situation, even though such a confrontation was rather pointless right now. The sound of the restroom door opening made both flip their heads to the side, the confused student who entered blinked as both Ari and Gaurav snarled at him, making him instantly backpedal in the wall behind him. It was the sound of the bespectacled youth's confused yelp that broke the aggressive spell which had been cast over both males, thus making them shake their head. 

"Okay, we're going to the medical center, like now." Before Ari could complain Gaurav was already dragging him out of the bathroom.

It took an hour of shouting and growling at one before the pair made it to their destination, though once they did so, hopping off of the bus with careless indifference to the clearly confused bus driver who had been watching them all throughout the ride, the pair noticed a sign at the front which sent them around to the back side of the building. Once at the rear of the medical center the pair were met by armed security, both of whom were muscular looking rottweilers wearing shades, and a couple of medical professionals who seemed to be expecting them. Ari reacted on instinct when two of the security personnel came up to them, putting himself in front of the tiger while snarling at the slightly shorter canines. 

"Hold on." One of the medial people, a petite redhead, said while putting her hand on the grunting canine's chest in a manner that was clearly less than professional. "I don't think these two are here to cause trouble." 

"No we're not, but my friend needs help." Guarav exclaimed while forcing Ari's sleeve up. When the woman gasped the tiger lifted an eyebrow in confusion. He then turned to see several more dark spots forming onto the raven haired hispanic's arm.

"Oh dear. It seems that you got one of the more active versions of the formula." She whispered while coming over to study Ari's arm.

"¿Que me esta pasando?" Ari asked as he felt a cramp form within his stomach once again.

"I'll explain everything after we get you inside." The woman answered, not at all phased by the sudden change in language, before turning towards the front entrance to the door.

Ari stepped forward without much thought, clearly wanting to get this over with, however Guarav grabbed him by the shoulder before he could get too far away. When the raven haired hispanic turned to look at his friend he immediately noticed the strained look on the tiger's face.

"What's going to happen to him?" The striped feline asked with clear worry lining his words.

"Who are you?" The redhead asked while looking the imposing college student up and down.

"I'm his adopted brother." Guarav answered without a moment of hesitation. 

Ari could only blink.

The medical professional couldn't hide her amused skepticism over such a proclamation, however in seeing the protective gleam within the other's eyes she chose not to aggravate the situation by questioning the other. 

"Your brother has been given a dose of an experimental drug thanks to an administrative mixup." She said after taking in a slow, deep breath. "We're going to take him down to one of the rooms here to see how far the drug inside of his system has altered his system." 

"Can I stay with him?" Guarav asked.

"I'm sorry, but no. However, if you give us your name and number we'll contact you when your brother's tests have finished being run." 

Guarav turned to look at Ari. 

For the first time in his life, the raven haired hispanic didn't know what to think or say, he never would have thought that the tiger actually cared this much about him, despite the sexual jokes he often tried to play, however, right as he stared into the other's amber orbs it was clear to see that Guarav was more than ready to fight down whoever he had to for him. It was a rather sweet gesture that made Ari blush somewhat. 

"I-I'll be okay," Ari replied with a slight stutter in his voice. "Could you go and check on grandma for me?" He asked before reaching into his pocket and pulling out his apartment key. 

"Uh, yeah." Guarav hesitated for a moment, clearly having not expected such a request, yet he straightened himself out once the cold metal of the key touched the pads within his hands. "Just hope she'll be able to understand me." He whispered low enough so that only Ari could hear him. 

The raven haired hispanic smirked at the striped tiger, he then moved his head forward to nuzzle the other against the side of the cheek completely unbidden. The touch made the tiger let out a few chuffs of relief in response to the touch, clearly enjoying it. When Ari pulled back he did so with a befuddled look covering his face. Guarav blinked in response.

"I think we should move along now." The redhead chuckled as she looked between the two college students knowingly. 

"R-right." Ari replied, somewhat shaken by what he had just done. 

It was only once his friend made his way into the medical center that the tiger turned to head back to the bus stop, his entire body shivering from the intimate touch he had just received.
