Ari was nervous when he entered his assigned room after being admitted to university. The dormitory building was a towering red-brick structure that seemed to hold both promise and intimidation in its weathered walls. He was never a very sociable boy, nor did he have much confidence or self-esteem, which caused him numerous difficulties in his school life, especially in high school, where he was the target of bullies. Despite this, his perseverance and hard work paid off, and he managed to get into a prestigious university with most expenses paid.

The somewhat stocky boy with glasses left his suitcases in front of the bed on the left side of the room - his designated space according to the housing assignment email he'd received a week ago. The room was modest but comfortable - two beds with simple wooden frames, a pair of desks positioned under the large window that overlooked the sprawling campus quad, and built-in closets that smelled faintly of cedar. Outside in the hallway, the bustle of students, both new and old, created a symphony of excitement - footsteps echoing on the tile floors, laughter bouncing off walls, the squeak of moving dollies, and animated conversations about majors, classes, and summer adventures. Ari glanced in that direction from time to time, waiting to meet whoever housing had matched as his roommate.

I hope it's not another bully. Ari thought while unpacking his things, arranging his textbooks on the shelf above his assigned desk, each one representing a step toward his future in physics.

"Good morning!" someone shouted from the door, it was quite a high-pitched voice. Ari looked up from his things and saw who was at the door. It was a boy his age; unlike him, who had a few extra pounds, he was quite thin, but had very lively eyes.

"Hi," mumbled Ari, once again his shyness diminishing his social skills.

"I think this is my room," said the boy while looking at a paper in his hand, then at something on the doorframe. "Yes, this is it."

The boy entered the room, still with that jovial look on his face, deposited his suitcases in front of the free bed, sat on the mattress, and turned back to Ari.

"I'm Malachi, nice to meet you."

"I'm Ari," Ari replied in a thin voice.

Malachi turned out to be someone quite similar to Ari after all, although, at the same time, diametrically opposite. Both were typical people who fit into the 'freaky' or nerd category, besides being gay, however, Malachi turned out to be much more sociable than Ari, as well as being very thin, while Ari was more stocky, though not obese; he had black hair, while Malachi was somewhat blonde; he wore spectacles, Malachi, contact lenses; besides having a more tanned skin tone, Malachi was, however, as white as milk.

Thanks to their common interests, they quickly became friends. Although they studied different majors: Malachi, engineering, Ari, physics. They had many classes in common, not to mention the time they spent in the dorm.

As time passed, both began to create habits, as well as grow their circle of friendships. The university's Gothic architecture and sprawling grounds became their playground. They found quiet corners in the ancient library where centuries-old books lined floor-to-ceiling shelves, perfect for studying between classes. The campus coffee shop, with its worn leather armchairs and perpetual scent of espresso, became their favorite meeting spot. Even the physics and engineering buildings, despite being on opposite ends of campus, seemed to have a pathway worn between them from their frequent visits to each other's classes.

It wasn't long before Malachi learned of Ari's impressive dungeon master skills, so every weekend was role-playing night. Their dorm room transformed into a haven for like-minded students - the desk lamps creating the perfect ambiance for their adventures, dice rolling across makeshift gaming tables fashioned from their textbooks, and the walls gradually accumulating hand-drawn maps and character sheets. They didn't just play Dungeons and Dragons, but countless other role-playing games. They also held small video game tournaments or watched series marathons, their room becoming a welcome alternative to the raucous fraternity parties that dominated weekend nights on the other side of campus. University life was stressful, with its endless lectures, demanding professors, and grueling lab sessions, but you had to know how to relax. While others went to the notorious campus bars or packed house parties, they created their own sanctuary of geeky entertainment.

The academic buildings, with their mixture of classical architecture and modern amenities, became their second home. Ari found comfort in the physics department's long corridors lined with displays of historical scientific instruments, while Malachi spent countless hours in the engineering lab's workshop, the smell of metal and electronics becoming as familiar as their dorm room. The campus grounds offered a peaceful backdrop to their friendship - whether they were crossing the tree-lined paths between classes, sharing lunch on the sun-warmed steps of the science building, or taking evening walks around the illuminated fountain in the central plaza.

Something they often talked about was how different the university environment was. Although Malachi hadn't had as many bad times with bullies in his high school, possibly due to his more extroverted personality, he did feel much more comfortable in the new environment of higher education. Both assumed that maturity came to everyone sooner or later, that people finally learned not to meddle in others' lives.

In the middle of the first semester, rumors began to spread that apparently there was a gang war developing in the city. Generally, it was a quiet city, but it seemed that there had been upheavals in the underworld and its rot had surfaced, affecting everyone in some way. Word spread that some people suddenly disappeared without a trace and that some of those gangs were behind the disappearances.

Neither Ari nor Malachi gave it much importance, they practically lived their lives within the university walls. Besides, they didn't frequent too many suspicious places, at most they went to some supermarket or took walks in the park, always in daylight.

One afternoon, however, Malachi didn't return to the dorm. Immediately, Ari reported what had happened to those in charge, but they didn't give it importance. "It's still early, he'll show up," they said, if it were someone else, Ari would have reacted the same way, but he knew Malachi very well, he wouldn't be absent at night. Nevertheless, he waited.

Morning came, there was no trace of Malachi. Again Ari called those in charge, who once again didn't lift a finger. He then decided to contact the police, but they didn't do much either, 48 hours hadn't passed, after all. He tried to contact him by phone, no signal.

It was exactly when 48 hours passed that Ari returned to the police station to file a missing person report. However, he began his own search. He printed posters with his face and put them up everywhere, also contacted other institutions, didn't stop calling him by phone.

A week passed, the police showed signs of giving up. Then another, despite Ari pressuring them, they excused themselves saying they had other work to do. By the third week, they closed the case. Even so, he continued searching, gradually expanding his search area, he wanted to at least find an answer.

Even when final exams came knocking, he made time to continue his search, he didn't want to give up. This brought serious consequences for his health. He was emaciated, although he got excellent grades in each subject, the dark circles under his eyes were terrifying, he almost looked more like a raccoon, he even lost a bit of weight from stress and the long walks he took each day through the city.

It wasn't until the second semester started that he himself lost hope. He had searched every corner of the city, yet found no trace of his friend. He was already adapting to the idea that he might have been murdered and his corpse was decomposing in some abandoned pit somewhere around the city.

Life went on, Ari had a new roommate, he wasn't a bad guy, but he didn't have such a close relationship as he did with Malachi. They barely talked to each other, they had completely different majors, so they didn't have classes in common either. All he had left were the friends he had acquired thanks to his former roommate, even so, it seems that with his disappearance, the group began to break apart. It was quite a lonely semester.

The rumors about gang wars remained, although they seemed to be calmer. However, disappearances continued throughout the city. People were terrified, the police overwhelmed, therefore, the population was also angry.

Mid-semester, Ari decided to rent an apartment, the memories that his university room brought were too many. Said apartment was a kilometer from the university, he could take a bus, but he preferred to walk, thus getting some exercise. From that moment, his life would consist of going from the apartment to the university and back, some days, of course, he went to the supermarket to buy groceries.

A few days after moving, he began to have the strange sensation that he was being followed, especially when returning from university, but no matter how many times he turned around, he found nothing suspicious.

That feeling of being followed continued, even intensified. He no longer only felt it when returning from school, but even when going to it. He tried taking new paths, venturing into more remote places in the city, even if it meant taking longer on his way, but that feeling persisted, even extending to other areas of his routine, like when going to the market. He started taking the bus or taxis, but he only avoided feeling that sense of persecution while in the vehicle, as soon as he got out, it returned.

He tried calling the police, but they were so overwhelmed with work that they barely took him seriously. He was becoming a bundle of nerves, it might have been paranoia, but he even believed he was being followed inside the university; not only in the hallways but even in the classes themselves, which was illogical, but there was that sensation, so even if he moved back to the student residence, he wouldn't feel safe.

It was already April when, after leaving the supermarket, he thought he saw his stalker. It was a tiger man, his fur was black with orange stripes, muscular, but rather athletic, not bodybuilder, with long limbs and light build. He was quite tall, more than two meters in height, wore black leather clothes that accentuated his musculature, as well as some piercings in his ears and eyebrows, he also wore a collar and leather bracelets adorned with spikes, as well as leather boots.

Ari tried to take a taxi, but it seemed today wasn't his day, as he didn't see any on the street. So he decided to try to lose him. He merged into a crowd, turned at an intersection, walked several streets, all crowded with people, but every time he turned his head he could see that figure behind. He then opted to go through well-intricate alleys. Right, left, right, left. He tried to make his trajectory as labyrinthine and erratic as possible, but that tiger kept on his heels no matter what he did.

He made a mistake when he turned right into an alley, he found it was blocked. When he tried to turn back, he found himself completely cornered by his pursuer, who approached calmly, emerging from the shadows like a predator.

"What's up, Ari?" said the tiger when he stopped a couple of meters in front of him.

"Who are you? How do you know my name?" asked Ari, sweat beginning to pearl his forehead.

"How could I not know your name if we're old friends?" replied the tiger with a malicious smile, showing immaculate and sharp fangs.

"I don't know you," Ari's heart was racing. He was clutching with all his might to the backpack he had placed in front of him, as a ridiculous attempt at defense.

"Ha, ha, ha," laughed the tiger. His laughter echoed in that alley like thunder. "Well, I suppose I've changed quite a bit since the last time we saw each other. But I'm sure if you look carefully, you'll know who I am."

"Look," continued Ari, "I don't have any anthro friends, neither in high school nor in university. So it's impossible that I know you."

"Come on, chubby kitty, think a little. You're the smartest in your year."

"What did you call me?" a shiver ran down his spine. The tiger in front of him widened even more the smile that drew his face.

"Chubby kitty. Brings back memories, doesn't it?" the tiger looked at him with almost predatory eyes.

"How do you know that? It was you! Wasn't it?" For the first time, Ari raised his voice, now he not only had fear but some anger. "Answer me!"

"Yes, I was the one who gave you that nickname, you're very stocky," The tiger's smile softened a bit.

"Stop playing games!" shouted Ari. "Don't you dare tarnish his name."

"Oh, someone was very worried about my absence," the tiger made a face like those made in front of something extremely cute.

"Stop saying nonsense! What did you do to Malachi?"

"Nothing," answered the tiger. "I already told you to use that privileged brain of yours."

"Shut up!" he continued shouting. "Stop joking and tell me once and for all what you did to my friend, where is he."

"And I repeat again that nothing, that you should look at me carefully and you'll realize."

"Then how the hell do you know the nickname he gave me."

"Because I am Malachi, you idiot," roared the tiger. Ari was left speechless. "Look at me carefully, I know I've changed a lot since we saw each other, but I know I still retain something from when I was human."

Ari, of course, did not give credence to these words. However, after carefully observing the tiger in front of him, he thought he distinguished something in its eyes, a spark of joy and joviality very similar to that of his friend Malachi. But it was impossible for that to be his friend. It is inconceivable that someone could change species. Besides, why would he do it?

"I still see disbelief in your eyes, but also some credulity,” continued the tiger who claimed to be Malachi, ”Okay, ask me something that only Malachi would know.

Ari didn't do it right away, he rummaged carefully in his memory to formulate the question well. Malachi had a lot of rather particular quirks, but he guessed that some of them were quite common, so he had to look for something that would identify him right away.

"The other days the Scorpion Man comic book you ordered arrived,” he said at last."

"It must have been a mistake,” Ari could instantly see the grimace the tiger made, ”You know very well I can't stand that character."

Ari swallowed dryly. He had made that comment as a trap, thinking that the tiger would appear gleeful, since many people thought that all nerds liked superhero stuff, especially the Scorpion Man. However, Malachi was quite selective about superhero stuff, in a general way he didn't like that genre, and, on top of everything else, he couldn't stand that character.

"Anything else I should know about that happened in my absence?" asked Malachi “Did my Dark Swordsman action figure, or as I normally call him (and it is in fact his original name) Kurokenshi, finally arrive?"

Ari was breaking out in a cold sweat. Malachi was a die-hard fan of oriental comics, not to mention that he learned all those bizarre names with impressive ease, plus, indeed, the said figure had arrived a few weeks after his disappearance.

"Yes, it arrived,” Ari stammered.

"Do you still have it?" asked Malachi. Ari could see that sparkle in his eyes again, he nodded.

"Perfect, as soon as we finish this you give it to me,” he smiled, showing a row of sharp teeth.

"Malachi, what happened to you?" Some tears began to form at the corners of his eyes.

"Let's just say I had some 'bad' luck,” Malachi replied "Remember the rumors of the gang war a few months ago?"

"Yes."

"Well, they were true,” Malachi answered. ”It was a very fierce war where all sides suffered casualties, either because members died or because they were imprisoned, however, the fighting did not stop, especially when a certain application began to circulate among the heads of the different gangs and criminal groups. It was an application that allowed you to alter reality, more specifically, people. You could change everything about them, except their memories."

"So they turned you into this?"

"Indeed. Due to the lack of assets, all the gangs began to transform innocent civilians to join their ranks. That's the disappearances that occurred during the time when I disappeared."

"But how did it happen?"

"One day I was coming back from the supermarket when I was, just like I just did with you, chased and cornered in a dead end. There I met the Boss, who immediately took out his cell phone, pointed it at me, touched a few buttons and transformed me into this. Since then I have helped him in the gang war, not to say that I turned out to be quite efficient, so much so that we were one of the winning gangs."

"But you never thought of escaping or going back to the way you were before?"

"No. I don't rule out that the Boss has used some function to make me his faithful henchman, but I admit that this new life and this new body,” he then began to flex his strong arms, which made Ari's penis give a slight jerk under his boxers, ”I've loved it. Being a thug has its advantages, there are no rules, only the ones the Boss sends you, which are few, truth be told, you're always having fun and there's a lot of sex. It's a lot more fun than the life I had back in college, I have hardly any stress".

Ari got a lump in his throat. He hoped there was something to rescue from his friend, but he could see in his eyes an intense fire, a fire that proved he enjoyed what he was doing. He could see that several times while they were together.

"Why did you show up now, after so long?"

"Although the gang war is over, our forces were severely depleted, so we have to recruit new people,” Malachi replied.

"That's why there are still disappearances,” Ari muttered.

"Bingo!" Malachi snapped his fingers to corroborate that information.

"So that's what you plan to do with me, you're going to turn me into an anthropomorphic gangbanger?" Ari's heart skipped a beat, the idea terrified him.

"As always, so clever,” Malachi smiled again.

"But why me?

"Isn't it obvious? You're my best friend,” Malachi replied, ”Besides, I know you've always wanted to be muscular and be surrounded by equally muscular men."

The mental image that formed in Ari's head was quite tempting. He saw himself with a sculpted torso, arms so strong that his veins showed, and a very broad back, and in turn, he saw himself surrounded by other equally muscular men, their bodies sweaty, bare. But as he remembered what he would be giving up, he again rejected the proposal.

"If there's one thing I appreciate about you, it's your stubbornness,” said Malachi as he pulled out his cell phone, tapped the screen several times, and pointed it at Ari, ”It will be very useful in the future."

"Malachi, what are you doing?" Ari panicked again, he searched uselessly for a way to escape, but his friend was blocking the only escape route. In former times he would not have found it difficult to move him, after all, he was always heavier than him, although most of his body mass was fat, but now Malachi possessed an overwhelming advantage.

"This debate has gone on long enough,” Malachi replied, ”it's time for me to do what I came here to do. Don't worry, when it's all over you're going to enjoy it."

Ari wanted to say something else, but a flash from Malachi's cell phone stopped him. It's not as if the light had dazzled him, but simply his body stopped completely, he could only breathe and see, but all other muscles were paralyzed.

Target detected, analyzing parameters.

Ari heard a voice with a certain artificial tone in his head. It reminded him for a moment of some of the animated series Malachi used to watch back in the day, the kind where the main character was transported to another world.

Name: Ari.

Species: human.

Age: 20 years old.

Height: 1.92m.

Weight: 100kg.

Constitution: overweight.

Percentage of body fat of the total weight: 60%.

Personality: shy.

Alignment: good.

Occupation: university student.

Orientation: homosexual.

Libido: 3/10.

Role: bottom, submissive.

Analysis completed. Do you wish to make changes in the subject?

A notification popped up on Malachi's cell phone screen, and he immediately selected “yes”.

Do you want to make the manual changes or let the AI make them according to what is in the best interest of your organization or you?

Malachi paused for a moment. He remembered that the Boss had told them something about this option, but at that instant he couldn't remember. Thinking there would be no problem, he checked “yes” on the application again.

Roger, beginning analysis of the organization's database. Analysis completed.

That was pretty quick. Malachi thought.

Initiating process of adjusting the subject to the new parameters.

Uninstalling the human pattern.

Installing the saber-toothed tiger pattern.

Ari wanted to say something after hearing that he was going to stop being human and become an anthropomorphic being. It's not like he hated them, in fact, he had even found several like that attractive in college. But transforming into one was something else entirely.

Installation process 5%.

Ari could feel a certain stinging all over his body. It was like when you put on a wool coat that gave you a slight itch that gradually went away. Unfortunately, he could not move a muscle, otherwise he would have noticed that the slight body hair was growing and becoming thicker. It started on the parts where humans naturally have body hair, then spread to the rest of the body. Unusually, the coloration changed from black to a light brown. The hairy areas of his body were expanding, came to cover his arms, except the palms of the hands, continued to join the chest and belly, places where, previously, there had never been body hair. On the lower part of his body, the legs were, like the arms, entirely covered with thick fur, except for the soles of the feet. This hair began to advance to the buttocks, another area where there had never been any hair, then down the back to the neck, then to the face, where, together with the beard and hair, they ended up covering the body completely with hair.

Installation process 20%.

The next changes occurred in the fingers, more specifically, in the nails. The nails grew rapidly, but instead of being flat, they began to curve inward until they became claws. On the palms, the skin began to bulge, forming pads of a pinkish hue, although in a matter of seconds it took on a darker shade, with a hard consistency to the touch, but at the same time soft when pressed. He also felt his teeth begin to change, mainly his upper fangs, which became progressively longer, even thicker. The rest of the teeth became sharper.

Installation process 35%.

Ari felt a pain in the area of his face, more specifically, in his nose and mouth. He felt his bones cracking, lengthening, reforming and fusing. It was a painful process, although, to some extent, relieving, since, with the increased availability of space in his mouth, his teeth were less crowded. He felt some cold on the tip of his nose, this was because it had been flattened and moistened. On the other hand, his ears were shifting to a higher area of his skull. Although he was not able to move them for the moment, he had the feeling that, from that moment on, it would be possible. They were also subject to a morphological readjustment, they stopped being typical ape ears, and became more feline, more in accordance with the big cats. Finally, he felt something begin to press against his underwear and pants, right where the butt meets the back.

Installation process 50%.

That time what he felt was heat, as if he was making the greatest effort of his life. His fur began to dampen with sweat. Also, he felt how every bone in his skeleton began to stretch, especially those in his limbs and spine.

Increasing overall height.

Burning fat deposits.

Synthesizing skeletal muscle.

The more he sweated the more he felt something inside him changing. Indeed, the muscle trapped under the layers of fat was slowly growing. At first he didn't notice much change because there was no significant change in his body weight, but once his body fat percentage was between 20 and 10%, he realized he was getting stronger. In that instant, he simply looked like someone who exercised regularly, he had acquired an athletic body, where every muscle was marked. His typical fatty man boobs and belly were gone, replaced by a well-marked abdomen and a strong chest.

These changes were not enough, after all, according to the AI data, they needed burly recruits, ready for street fights, whose appearance alone would intimidate their opponents, as well as not being easy to kill. So, although he had added a few inches to Ari, who now boasted the impressive height of 2.13m, he also began to add more muscle mass. His already prominent V-shaped torso began to widen, his shoulders became rounder and more robust, his trapezius began to rise, his neck to thicken, his Adam's apple to become more prominent. At that moment he could not speak, but, had he done so, a new bass voice would have emerged from his throat.

Ari couldn't quite see what was happening to him, but he could feel his clothes getting tighter as the seconds ticked by, it was impossible to deny it, he was liking everything. It was impossible to deny it, he was liking it all. He often considered doing some exercise and getting in shape, but his laziness and lack of incentive prevented him from doing so, so he just stayed the way he was, a chubby boy.

His attention returned when he heard something tearing. Had he been mobile, he would have seen that both the sleeves of his sweater and his chest area had been torn, so that he could already glimpse the impressive pectorals, which, like mountains, kept growing, as well as his arms, which had become so muscular that the veins could be seen, even under the coat of fur.

Ari had an unbearable urge to move. He wanted to touch every part of his growing body, flex every new muscle, but, as long as he was under the force of the application, he could not.

The next to develop was his back. It grew so large that his arms had to adopt a new posture, one that would eternally show off his magnificent chest. The muscles on either side of his spine grew so much that a deep valley formed above it, furrowed by the cyclopean plateaus of his muscles, separated in turn by other valleys. By this time, Ari had become a mountain of muscle.

Immediately, before the newly acquired weight did significant damage to her lower body, her legs began to swell, as did her buttocks. Never in his life would he have imagined that he would have such a round, seductive ass, not to mention legs as sturdy as the columns of a Greek temple.

Installation process 65%.

Initiating psychological correction.

A pounding headache invaded Ari. It took him a couple of minutes to realize what was happening: a fresh stream of memories was being put into his head. At first, they were incongruous, blurry images, but, as time went on, they became sharper and more understandable.

He saw street scenes, people wandering through bars and nightclubs, drinking, dancing, smoking, having sex, lots of sex. He saw them walking through the dark alleys of the city, vandalizing, fighting, having fun. All these scenes seemed horrifying to him at first, that was not his life, but school, study, research....

But it didn't last long. He began to question his life. Yes, it was fun, he had friends, they played video games and RPGs, watched movies and series, but was that really fun? These guys that were now flooding his mind seemed much more cheerful, with no laws to follow, other than those of his Boss.

Installation process 80%.

Yes, definitely that life was much better, no worries, no owing explanations to anyone, no stress. It was so stressful every time the exams came, every time a project had to be done, and he had to have good grades to keep the scholarship. For what? To then look for a job, maybe, if he were lucky, he would go to a research center, to then go back to having to study for a master's degree, then a Ph.D. Was that really fun?

No.

This new life was much better. He would live on the edge, between pleasures and danger, but he wouldn't be alone, not like now. He would have his gang mates, his Boss, they would be inseparable. From party to party, from club to club, from bar to bar, from bed to bed, from fight to fight. It would be nothing but dopamine and adrenaline, a life full of exciting sensations.

He already understood Malachi's words. Definitely, once the transformation was over, he would not want to go back to the way he was before. A pathetic human, weak, insecure, fearful, he was now a saber-toothed tiger, strong, powerful, proud, libidinous, violent. He wanted to have fun now, to beat the shit out of any asshole who messed with his gang, and to bust the ass of any male he wanted.

Huh? Wasn't I bottom?

Installation process 95%.

Of course not! How could he be a bottom with such a monumental body capable of destroying a skull with his own paws? He served to dominate others, show them who's boss, make them worship his titanic body, inseminate them until they bore him children, use them as condoms, and then discard them. That was him, Ari, the saber-toothed tiger.

Just before the AI terminated the transformation, the remnants of Ari's old clothes, which by then were nothing more than twists and turns, changed for something more in keeping with his new personality. Black leather boots covered his feet, tight pants of the same material, his legs, a black belt adorned with some metal inlays, with the buckle in the shape of a saber-toothed tiger's head, held him in place. A sleeveless white shirt, rather small for his monumental figure, first covered his torso, then, a black leather jacket, equally sleeveless, to show his portly arms, which he wore open to show off his impressive chest. As a final touch, a thick chain encircled her neck, as well as some piercings in her ears, eyebrows and nose, as well as in her two nipples. She also had a huge tattoo that covered almost her entire arm.

Installation process completed. I proceed to update the user data:

Name: Ari.

Species: saber-toothed tiger.

Age: 28 years old.

Height: 2,13m.

Weight: 250kg.

Constitution: muscular (bodybuilder).

Percentage of body fat of total weight: 15%.

Personality: Arrogant.

Alignment: bad.

Occupation: gang member.

Orientation: homosexual.

Libido: 9/10.

Role: top, dominant.

“What? What do you mean, top and dominant?” shouted Malachi, completely dismayed “No way, you should be a needy, submissive bitch.”

Ari didn't pay much attention to his friend's words, he could finally move, so he took advantage of every moment to explore his new body. He took out his cell phone to, through his front camera, see himself. His penis twitched a little after seeing his face, truly this new look was much better than his old self. This one radiated masculinity, it would make anyone who looked at it melt, make everyone, male or female, want to suck his cock or have it completely buried up his ass.

“Now I understand why you didn't want to go back to your old form,” Ari said as he continued to admire his majestic body, his voice echoed in the alley, which made Malachi raise his eyes from his cell phone.

“Who the fuck would want to go back to being a pathetic human when you have a body like this?” Ari roared. Malachi, on the other hand, swallowed dryly, at the same time his cock spasmed.

“Shit, I'm horny,” Ari complained. His hand went straight to his crotch, then he looked at Malachi and smiled, “Don't you think you could give me a little help?”

Malachi didn't answer, but backed away as Ari moved towards him. He was pacing softly, as if gloating over his prey, licking his lips and massaging the bulge that was forming in his pants. Malachi's heart was racing, his instincts screaming that he must flee at any cost. When he was finally strong enough to make a run for it, he found himself in front of one of the walls. He tried to turn toward the exit, but was stopped by a muscular arm.

“Where were you going?” said Ari as he blocked Malachi's other step with his remaining arm. “Come on, I'm pretty sure there are very few men like me that you'd be willing to take it in the ass with.

Malachi tried to refute that, but it was true. Ari at that moment radiated an overwhelming masculinity. He was nobody compared to Ari, if there was anyone he was passive about, it would be Ari. Still, he tried to resist, his own pride wouldn't let him.

“I see that you are still undecided,” Ari had no sooner finished these words than he pounced on Malachi and planted a kiss on his lips. It was so sudden that the black tiger had no time to react, for, in no time, the saber-toothed tiger's tongue was already inside his mouth. It was a thick, long tongue, one that quickly reached the very bottom of his mouth. Ari's lips, on the other hand, sought hers, sucked on them, bit them as her tongue explored every corner of his mouth. It was the best kiss she had ever had so far, a kiss that melted all thoughts of resistance, as she had realized who was in charge.

When Ari broke the kiss, who looked at Malachi's face, he could only see an expression of desire and lust on the part of the black tiger. He moved a little closer and placed his hand right on the other feline's crotch, indeed, they also boasted a strong erection. He played a little with his genitals, stroking them, occasionally giving them a squeeze, only to hear Malachi moan.

“Do you want me inside you?” Ari asked.

“Yes,” Malachi answered in a moan.

“Well, you'll have to wait,” Ari added. After which, he took off his robes, sat down on the floor of the alley, and wiggling his toes, invited Malachi to come closer.

“Give them a good massage, feel them, enjoy them,” Ari ordered. Malachi had never thought of himself as a foot fetishist, but, again that aura of Ari's dominance subdued him. So he knelt down on his knees and began massaging Ari's right foot. He tickled each of her toes, also pulling them lightly. Then, using his fingers, he began to make clockwise circles at various points on the sole of his foot, first on the metatarsal, then in the middle of the instep, and finally on the heel. Further on, he pressed his thumbs together and moved them from bottom to top.

“Do you like my feet?” Ari asked.

“Yes,” Malachi answered without taking his eyes off that sole. He had begun to wrap his two hands around the saber-toothed tiger's feet and then made circles around them.

“Well, from now on, this will be your new role,” Ari said.

“Yes, Ari,” a sense of happiness flooded Malachi's mind, ”I want to serve these feet, I want to serve you.

“Well, go on,” Ari spat, ”in fact, clean them.

By this time, Ari's every word was an unbreakable command to Malachi, so, without any resistance, he lifted that same foot he was massaging and began to lick it. It didn't taste bad, it didn't smell bad either, just the sour smell of the sweat of an alpha male, of the male he served. With his tongue he carefully explored the surface of that foot, every slope of each of the pads, the little wrinkles that were made, the spaces between the toes, there was not a millimeter that was not moistened by his saliva.

“Do you like the taste of my feet?” Ari asked as he spread his toes wider for Malachi to delve deeper with his tongue.

“I love them!

“Well, now these feet will take care of other business. Lie down on the floor,” Ari ordered.

Malachi again obeyed, whereupon, Ari stood up, positioned himself right on top of Malachi and, with his right foot, pressed down on Malachi's muzzle, while another, resting his heel against the floor, massaged and pressed down on Malachi's genitals.

“Do you like the smell of my feet?

“Yes,” Malachi moaned, ”it is the smell of a true male, one I must serve unconditionally.

Ari opened and closed his fingers on Malachi's muzzle, massaging, as well as making him sniff every nook and cranny of his feet. On the other hand, he continued to stimulate the tiger's crotch, where a powerful erection was taking place, even, a spot of pre-seminal fluid was forming and expanding.

“Well, enough of the games,” Ari pulled his feet away from Malachi, ”It's time for action.

With his strong arms, Ari lifted Malachi's weight, put him against the wall, tore his clothes and pulled down his pants. Malachi didn't put up the slightest resistance, on the contrary, the rough and wild behavior of his one-time friend turned him on even more. Ari then proceeded to kiss him, a kiss as brutal as all his actions from the moment he was transformed. There were moments when Malachi was even short of breath, but he didn't balk, he wanted more.

Ari then proceeded to kiss and bite the tiger's neck and shoulders. Malachi, for better support, grabbed onto the saber-toothed tiger's waist with his legs, even though he put almost all his weight on Ari, Ari didn't flinch, that's how incredible was the strength of this new Boss’ recruit. Taking advantage of this, Ari began to enjoy his old friend's body more at ease, Malachi did the same: he explored every furrow of his lover's huge back, while Ari sucked one of his nipples, under them, a pool of pre-seminal fluid began to form.

When he could take no more, Ari pushed his penis into Malachi's anus with one thrust. It was huge, 20cm long and 15cm in circumference. Malachi stifled a scream as that monstrosity penetrated each of his sphincters without prior preparation, but it didn't take long for him to enjoy the tiger's savage onslaught.

“Oh, how big!” Malachi moaned, or, because of the thickness of his voice, growled.

“Keep moaning like that, whore,” Ari growled in his ear.

“Yes, I'm your whore, break me full.

“This is your “punishment” for turning me into this.

“Yes, this is my punishment,” Malachi admitted in ecstasy with Ari's brutal onslaught “destroy me whole.

Ari's penis moved in and out with increasing speed with each thrust he made. Thanks to all the preseminal fluid he had generated, and was generating, there was virtually no friction, despite how tight Malachi's walls were. The tiger kept his mouth open, his tongue hanging out of the side of his muzzle, and his eyes were turned all the way up. It was very likely that it would not walk properly again for quite some time after the savage onslaught of the saber-toothed tiger.

Finally, something warm, much more viscous, was injected into Malachi's bowels, Ari, on the other hand, flexed his hips forward as far as he could, his penis penetrating even further into Malachi's rectum. They both roared from ecstasy, for, soon after, Malachi also ejaculated, the roar of both of them echoed in that alley.

The app proved to be quite useful, as, with a few taps, it returned the clothes as they were to Malachi, after which, he led Ari to where the gang was. They walked through intricate alleyways never seen by in now saber-toothed tiger, each alleyway seeming even more shady and dangerous than the last. He was able to run into some whores several times, some alone, some in groups, some with a client; he also saw other gang members, humans or man-beasts, most of them, as hardened as he was, he even saw policemen making deals with them. As they went deeper into those alleys he could discover the other side of the city, a darker one.

They arrived at a street full of bars, nightclubs, as well as brothels of all kinds and for all tastes. It was already dark, so the countless neon signs illuminated that area, highlighting the den of perdition it was: a dirty street where people wandered around drunk, drugged or looking for fun, dressed in corporate suits or the latest street fashion. You could watch without much shame as sex workers orchestrated their trade on street corners.

Malachi led Ari to a bar located practically at the end of the street. It was a small one, with a lion's head sign on its door, illuminated by red lights. Inside, Ari found the place quite full, most of the diners were felines, big cats to be more specific: tigers, jaguars, leopards, pumas, lions, all as muscular as he and Malachi, and dressed in the same clothes. They were quietly drinking and chatting, some were playing billiards, others, darts, a few, in more secluded corners of the bar, where there was not much light, in slightly more intimate acts.

The tiger raised his arm as a greeting to all present, who immediately returned it with a smile on their faces. Both friends continued on their way, navigating between the tables of the bar until they reached a staircase where a black panther as tall as Ari was sitting. Malachi said a few words and it let them pass, they climbed the wooden stairs, the black tiger always leading the way. Once on the second floor, they turned left, at the end of the hallway was a door, also flanked by two guards, this time, a pair of leopards.

“I have to see the Boss,” said Malachi, looking the guards in the eye, ”I have already accomplished my mission.

The guards nodded, Malachi turned the doorknob and entered the room. It was a rather spacious room, quite well decorated, it didn't look like it belonged to a thug or gangster: a few pictures of some renowned artist hung on the walls, an imperial bed was in the center, with red and orange silk sheets, with a mahogany frame with carvings of feline motifs. To one side, there was a chair, of the same wood and ornamented with similar motifs, on which sat a lion. The lion looked to be in his forties or fifties, his mane was dotted with gray hairs, his abdomen was no longer so flat, although he was not obese, for the muscles of his arms and his strong chest were very noticeable. He wore a sleeping robe, red like the bed sheets, he smoked a huge tobacco, while in his other hand he held a glass of red wine, everything about him gave off a regal aura, he was, without a doubt, the Boss.

“Well, well, I see you brought a guest,” the lion moved his lips, his voice reverberated in the room, for the first time since his transformation Ari felt fear.

“That's right Boss,” Malachi replied, trying to sound as resolute as he could, but Ari could sense a hint of nervousness in his voice.

The Boss didn't say anything for a few moments, he just watched Ari carefully, every now and then he took a puff of tobacco and a sip of wine, but he didn't say anything else. Ari was even more nervous.

“Good addition,” said the Boss, ”I predict he's going to be one of the best recruits yet, what's your name, son?

“Ari... sir,” answered Ari, for an instant he remembered his old life, how he was so shy and had such a hard time talking to strangers, the idea that he had returned to that state terrified him.

““Relax, son, as long as you follow my orders you have nothing to fear,” the Boss seemed to have noticed his state, a warm, fatherly smile appeared on his leonine face, something that calmed Ari considerably.

The lion continued to watch Ari closely, his eyes were inquisitive, the saber-toothed tiger could not imagine what was going on in that gentleman's head.

“You used AI for the transformation, didn't you?” The lion then turned to Malachi, who again stood at attention and swallowed dryly.

“Yes...

“I can tell,” the lion interrupted him, ‘I can imagine what happened after the transformation,’ a laugh as loud as thunder came from the lion's throat, both Malachi and Ari blushed.

“I warned you about it, Malachi,” the lion continued laughing.

Malachi did not answer, but lowered his head in embarrassment.

“I would have liked to witness that moment,” the liquid in the cup swayed with the lion's laughter, ”You always made yourself the dominant one since you transformed. As for you, Ari, congratulations, you made one of the toughest bones in the gang into your bitch.

Ari couldn't help but be infected by the Boss’ joy after hearing those words, the laughter of two felines flooded the room.

“Although it is a little early,” the lion slowly regained his composure, ”I have the impression that you will be one of my main subordinates. You have a good constitution, as well as an aura of dominance. I can't immediately place you as one of my “commanders” because you haven't even been in our gang for a few hours, but don't be impatient. Once you prove yourself, no one will doubt my decision.

Ari's face lit up with those last words.

“Now,” continued the Boss, ”go out and enjoy the rest of the evening. Malachi, tomorrow you will explain everything about us to him, that includes introducing him to everyone and introducing him to the main business of the gang.

Malachi bowed, which was imitated by Ari, after which they both left the room and headed for the bar.

Although they had been behind closed doors, it seems that the news had spread throughout the bar, since, as soon as they went downstairs, they were greeted with enthusiasm by everyone present. The first thing they did was to invite him to a few drinks, in a corner of the bar, where there was a small stage, some of them started to play some rock song, the establishment was filled with more life.

Ari was quite busy all night telling about his old life and what his transformation was like. He knew that, at that time, most of the people present had been humans at some point, coming from different places and backgrounds: some were students, others office workers, a few even academics. The age range was also quite wide, from 18 year olds to 60 year olds, yet it seemed that the application leveled them to a range between 20 and 30 years old. He also learned that the marital status was also varied, some admitted that in their other life they were married and even had children, but had no desire to return to their old lives, not to mention that there were no heterosexuals.

As he realized upon entering the bar, interpersonal relationships were quite flexible in the gang. Sex was easy, you could do it with whomever you wanted and even as many people as you wanted, while there were their partners, they were pretty open. It didn't take Ari long to catch the attention of several members in the band. He instantly noticed the stares of several felines on him, in addition to the attentions he was receiving. He started with the leopard who was acting as barista at the time, and after giving him another mug of beer, he gave him a kiss as passionate as the one he gave Malachi when he transformed. A cougar, not so discreet, unzipped his pants and pulled out his penis that was already well erect after seeing so much virility in the environment, after which, he gave him a blowjob. Ari pushed the cougar's head so he could swallow his 24cm of thorny cock full all the way down his throat. The cougar turned out to be an expert, as he didn't gag at all. Once he had finished being milked, he got up from his seat and walked around the bar a bit, until he was intercepted by a jaguar, almost as tall as he was, but less massive. It was as if his testicles were overproducing, as his penis came back to attention. He pushed the jaguar to a wall of the bar, lifted it in weight, and fucked it right there.

In his other life, Ari, at most, would have had only one sex session in one night, but with his new look, he lost count of the number of times he ejaculated in that bar, the number of times he destroyed asses, was milked or milked himself (protein had to be replenished after all). It was a turbulent night, full of sex and alcohol, he lost consciousness at some point, when he woke up, he was surrounded by other felines, all naked, exposing their titanic bodies, tanned with muscles and adorned by tattoos and piercings. He was definitely not going to miss his old life.

Two weeks had passed since Ari was transformed. Little by little he was introduced to the things of the gang, the first thing was the name, Red Claws, in reference to the color of the Boss’ mane. Then the different businesses they did, most of them were arms trafficking, although they were also involved in clandestine fights, where many of its members were participants, either as organizers or as fighters. They also owned an exclusive men's brothel, attended by women, mostly wives of bigwigs whose husbands no longer satisfied them very well in bed or simply had exotic hobbies, as well as men, politicians who were wearing a cover, as simple millionaires and others who were simply looking for a fun night in the company of burly men.

Ari participated in two arms orders, as well as in a fight, and also acted as a guard at some of the Boss’ meetings. He quickly won the affection of all, both for his loyalty and diligence, as for his gifts as a lover, in addition to his stamina in the private gym of the gang, where only members could enter and it was, in fact, mandatory attendance at least three times a week, in practice, all members went at least five times a week and spent up to three hours of intense training.

On the other hand, at the university, it didn't take long for Ari's absence to be noticed, especially since he was a scholarship student. The search efforts began immediately - his family and closest friends were contacted, his frequent locations were investigated, even his itinerary from the last day he was seen. Unfortunately, like almost all disappearance cases that had been occurring in the city, nothing conclusive was found, so the case was archived and the scholarship canceled.

Deagan and Chris were two of Ari and Malachi's closest friends, although after Malachi's disappearance, they had grown somewhat distant due to Ari's obsession with searching for him. Both were Chemistry students in the same year as Ari and Malachi, and although they didn't share classes, they met by chance at a themed event for a franchise that all four enjoyed, held in the city. Unlike Ari and Malachi, they were heterosexual, though unlucky in love. They weren't very athletic either, being rather thin with slightly below-average height, but not unusually so. They didn't wear glasses, and their clothing was generally average, though they occasionally wore themed clothes featuring their favorite bands or franchises.

When they learned of Ari's disappearance, they were shocked. They knew well that Ari wasn't one to frequent shady places, though perhaps in his quest to find clues about Malachi's whereabouts, he had ventured too deep into the city's dark side and met the same fate. They were among the first to volunteer in the search for their friends. Both students and faculty were beginning to panic, as Ari and Malachi weren't the only ones who had disappeared in recent days.

It was difficult to balance the searches with schoolwork, but following Ari's example of searching for Malachi for months, they didn't want to give up so easily. They searched during the two weeks that the official search lasted, and even longer, but as with Malachi, nothing was found.

A week after Ari's official search had ended, Deagan and Chris were at the university cafeteria having coffee. Their spirits were low after realizing how fruitless the search had been. The cafeteria was almost empty, as it wasn't lunchtime, so only a few murmurs could be heard here and there. Deagan was listlessly stirring his strong coffee, perhaps watching the steam rising in the air, while Chris was looking at his phone, having finished his cup of tea moments before. It was then that a message notification appeared on his screen. At first, Chris didn't pay much attention to it, but when he read the sender's name, it caught his attention. He immediately called Deagan over to look. Neither of them could believe what was happening.

Chris, how is everything? I found Malachi. Come with Deagan to this address.

That's what the text message he had just received said, and right below it was a location link. Neither Chris nor Deagan could believe what they were seeing. They made sure it was Ari's phone that had sent the message, though it could well be someone else using it. They considered contacting the police, but just then, another message arrived.

No need to call the police, it's just a meeting among friends after all.

This made it even more suspicious.

It's us. We're simply going somewhere else, we even withdrew from the university. You can check.

They followed that last suggestion, just to be sure. Indeed, a few days ago, there had been calls to cancel both Ari and Malachi's university enrollments. The reason appeared to be that they were going to another university. Both found this extremely strange; after all, Malachi had been missing for months, Ari had been searching frantically for him everywhere, then he too disappeared, and now they suddenly appear as if nothing had happened.

"I think we should contact the police," said Chris as they left the university grounds.

"I also think everything is very strange," Deagan agreed. "But if we received confirmation from the university itself..."

"It's a shame we don't have their families' contacts," Chris interrupted.

"We could go back and ask at the secretary's office," Deagan suggested.

"I doubt they'll give us that information," Chris argued. "It's too personal."

"And I don't think either of them has many friends from their hometowns," added Deagan, after which he sighed in disappointment. "We have no choice but to trust."

Chris nodded. They were lucky to catch a bus that would take them quite close to the meeting point.

The journey was short, barely five minutes. The bus dropped them off at a fairly busy plaza, from which they took the street on the right. It was an area more or less in the center of the city, so it was quite busy. People came and went, absorbed in their own thoughts, with the sound of cars and the bustle of pedestrians being the most prominent sounds. They walked for a few minutes before turning onto a less crowded side street. It wasn't until they reached a rather deserted spot that they started to worry.

It was quite a remote place, the buildings were made of brick, so it was quite an old area. Some graffiti decorated the walls and papers were blown about by the wind. Chris and Deagan, after seeing the scene, didn't think twice before turning around.

"Leaving so soon?" they heard a deep voice behind them, a voice that reverberated in that place. The boys turned their heads to see who the voice belonged to and found themselves facing a very muscular, gangster-looking saber-toothed tiger.

"Aren't you going to greet your friends?" they heard another voice coming from the street they had entered through. It was less deep than the saber-toothed tiger's, belonging to a black tiger with orange stripes, almost as muscular as the first one.

Seeing that escape route blocked, they decided to take another path to the right. Both broke into a run, running as fast as their untrained legs would allow.

"This will be fun," was the last thing they heard before entering that alley.

They ran and ran, every time they saw the alley turning somewhere, they took that detour without thinking twice. They could hear the laughter of the two beast-men, who apparently weren't even running. That was bad, as it meant they were completely sure they would catch them.

Their hopes of escape vanished when, at the last turn, they found themselves at a dead end. Both stopped right in the middle, mouths open and panting, sweat running down their foreheads and soaking their pullovers - they were exhausted. As they feared, their pursuers appeared right behind them.

"This brings back memories," said Ari.

"Heh, heh, even for me," added Malachi.

"Seems history repeats itself."

"Who are you?" Chris raised his voice between pants.

"Well, there have been some changes, but I'm sure if you look carefully, you'll know who we are," answered Ari.

"Seriously, everything is repeating," Malachi laughed.

"What did you do to Ari? Where's Malachi?" Chris continued interrogating.

"We are them," Ari answered.

"Enough with the jokes!" Chris shouted.

"I know it's hard to believe, but it's the truth," Ari shrugged.

"Ari and Malachi are human," Deagan finally said.

"Were," Malachi corrected.

"That doesn't make the slightest sense," Deagan argued. "Not even with hundreds of plastic surgeries is it possible to change someone's species."

At that moment, Ari took his phone from his pants pocket and showed the screen to his incredulous friends. On it, some words could be distinguished, as well as a photo of a generic person.

"But this application can," answered Ari, who then turned the screen toward himself and pointed the camera at his friends.

"Did you finally confess to Megan, Chris?" asked Malachi. Chris didn't answer immediately, but stared at him perplexed for a few seconds.

"How do you know that?" Chris stuttered.

"Because, as far as I know, you only told me about that, Chris," Malachi responded with a wide smile that showed all his sharp teeth.

"What are you talking about?" asked Deagan, clearly confused.

"About things that only you and we know, Deagan," answered Ari. "Like your crush on Professor Murdoch, for example."

Deagan's face turned red as a tomato. Only Ari knew about his feelings for that statistics professor.

"Well, I think you're now convinced that we're telling the truth," Ari continued. "Let's move on with the rest."

The generic photo changed to that of Deagan and Chris, and below it, their characteristics began to display.

"Remember not to use the AI,” said Malachi, who was also smiling, ” although I'd like to see the result."

"Are you so eager to see someone busting my ass?" Ari looked at him questioningly. -I won't give you that benefit.

He continued touching the screen to change the values of his two friends' statistics, who had not moved one iota from their terror at that moment.

Initiating recalibration.

Both Deagan and Chris were paralyzed just like Ari had been when the application began to operate - they couldn't even speak a word.

Both were even more hairless than Ari had been while human, however, just like him, hair began to sprout over their bodies, first in areas where it normally grows on men, then spreading to the rest of the body. This hair was somewhat yellowish, though, especially in Deagan's case, what started growing on his chest and abdomen was lighter than on his arms and legs, not to mention that in these regions, some patches of hair were even darker, almost black, though with a curious pattern: they were like atolls with dark borders, smaller spots of the same color in the interior, and the rest lighter.

As the hair grew and spread across the body, its density also increased. In a matter of minutes, it could be called fur, which now covered practically all of both boys' bodies, except their faces. But this didn't last long - their beardless jaws also experienced unprecedented hair growth, which, in Chris's case, was atypical: the front part of his beard and mustache (around the mouth) acquired a whitish coloration with a black border, while the rest was the same sandy color as his body fur. Once they had acquired thick beards, the hair continued spreading to their heads, which added another peculiarity to Chris's fur: the area under the tear ducts also acquired a blackish coloration. By the end of the first stage, both young men looked as if they suffered from hypertrichosis, as every part of their bodies, except for their palms and soles, was covered in dense fur.

Just as it happened with Ari, Deagan and Chris's transformation occurred in phases. After the first phase concluded - the acquisition of fur - came the growth of claws and the sharpening of teeth. This latter change, along with the skeletal reorganization of the face, was a painful stage for both, because they still wore braces. They suffered considerably while their faces elongated forward to create muzzles, but the moment the metal wires broke, the rest disappeared instantly, which left their teeth completely free and impeccable, entirely white. Another somewhat uncomfortable process was the tail - they felt some discomfort while their tails pressed, first against their pants, then against their underwear, and felt immense relief when they broke through the fabric. At first, they were as hairless as their bodies had been, but in a matter of seconds were covered by a layer of fur similar to their bodies'.

Once the species-related changes were completed, which happened with the transformation and movement of the ears, what Ari and Malachi found most exciting began: muscular growth. Since Deagan and Chris were so thin, the change was much more impressive. Although they didn't wear very loose clothes, since they said they didn't like looking like kites, their clothes weren't very fitted to their bodies - there was some space between their scrawny arms and their shirt sleeves, their chests were nonexistent, and their torsos were completely rectangular.

The addition of mass was constant over time, but it was noticed more quickly in the arms, as in a matter of seconds, they had doubled in thickness. They weren't yet constrained by the fabric, but it was only a matter of time. Deagan and Chris felt strange at that moment - they couldn't move, but they could feel each of the changes in their bodies. At first they felt terror, but as their arms kept thickening and the sleeves felt tighter, they couldn't feel anything but joy.

The arms continued growing. Their hands, so delicate, typical of intellectual people, gained thickness at the same time as the rest of their extremities. They became thick, like someone who has performed physical tasks for too long. Their forearms became powerful, with veins branching under the skin, their wrists were no longer bony - it would probably be impossible to wrap fingers around them, not even Ari's, due to the thickness they had gained. As for the biceps, triceps, and shoulders, they exploded with power, eventually tearing the shirt sleeves to display their magnificence - they were as thick as their thighs and, due to the low percentage of body fat, well-defined, even under the fur they had acquired.

The trapezius muscles gradually elevated as they gained more body mass, though they ended up being more defined in Chris than in Deagan. Their necks also thickened, the new influx of testosterone made their Adam's apples grow larger, which caused their voices to become much deeper, though not as deep as Ari's.

It was spectacular to see how their pectorals projected forward. At first, they simply started to be defined in their chests, then began to gain mass. Gradually they added more and more muscle until, at first, they started to show slightly under the shirts, then pushed forward, constraining under them. By the time their arms had torn the sleeves, the pectorals were about to do the same - it started with a tiny tear that followed the body's axis, but with the passing seconds grew along its entire length until exposing both felines' magnificent pectorals, so large and solid that their extremely full nipples pointed downward. They were so large it was impossible to encompass them with a single hand.

By then, the rectangular shape of their torsos had been erased, replaced by a V-shape, but it was still somewhat subtle. It wasn't until their lats started to grow that the V-shape became more evident. Their arms had to separate somewhat from their bodies due to the width their backs were acquiring, which, furthermore, projected their broad chests even more. A deep groove formed right over the spine, on whose sides other grooves also appeared marking each muscle present in the back. Both boys' hunched walking was quickly corrected, as they stood up with entirely straight backs.

Deagan managed to acquire a much more defined abdomen than Chris, although both had quite appetizing midsections - Deagan's almost without fat, so each of the six abdominal muscles was clearly defined; Chris's with a slight layer of fat, which simply accentuated the size of said muscles more.

A pair of legs strong enough to carry the kilos of muscle in the torso was necessary, something that didn't take long to appear. Hundreds of tears started to appear in their pants as their leg muscles grew. Their buttocks, barely noticeable at first, quickly became round and juicy, with the perfect mix of muscle and fat, though it was Deagan who had the more appetizing behind, so round it invited spanking.

As for the legs, in just a matter of minutes they went from being toned, to athletic, to muscular. Just as had happened with the wrists, the shins were no longer too thin, as the tendons thickened and some fat was also deposited around them.

To change the psyche of both of them, the application had to work more than with Ari, after all, it had to change the sexuality of both of them, so it gradually changed their tastes. It started by looking for the type of girls they were both attracted to, in the end they turned out to be quite predictable: voluptuous girls with big breasts and lush hips. He then began to alter certain attributes of the images that would normally excite them: first, he enlarged the size of the clitoris, then he closed the vagina, erasing any element that reminded him of a vulva and replacing it with male genitalia.

At first they were tiny, on the scale of micropenises, but as time went on, the dimensions increased. The testicles began to hang conspicuously, became round and heavy, the glans grew longer, thicker, juicier, especially in the mind of Deagan, who, after all, would prefer to act passive. In her head, the penises began to take on scary proportions for many people, long and thick, Chris, on the other hand, was seeing them getting rather thicker, but the length was more average.

Once both had acquired the mental image of transsexual women as the object of their fantasies, the AI continued to modify that image. The breasts began to shrink, the shoulders to broaden, though only slightly. The person in question still possessed feminine qualities and attitudes, but a hint of masculinity was appearing. The hair became shorter, although the body remained mostly hairless, with a practically non-existent musculature, to enhance femininity.

The femboy image was short-lived, although it remained in some corner of their psyches as one of the many choices of partners to have. Now, the AI focused on reducing the width of the waist, slimming that figure, giving it more masculine features, but still retaining some joviality. Some muscle appeared under the skin of that image, but only a little, to show that it was a boy, a twink.

Like all people, the twink had to grow up, it might lengthen his youthful image for some time, but perhaps he would discover that slightly more mature and tanned bodies were not so bad. Gradually the muscle grew under the skin, the twink gained some muscle mass, his body was a little more athletic, his torso, less rectangular, his chest, better developed. He didn't have to act feminine, but as he wished, so a little more masculinity wasn't bad: going to parties, getting drunk, growing a beard from time to time...

It was from that point on that the image began to divide and give rise to hundreds of options: different male bodies began to appear in their memories: more athletic, fatter, more effeminate, more masculine, younger, older. Images of women were less and less, more and more distant, like an old memory to be buried deep in the subconscious.

Certain intrusive sensations and thoughts, as well as doubts, slowly crept into their minds.

How did one satisfy a girl?

Wouldn't satisfying a boy be easier?

How would semen taste?

How will another man smell?

Is anal sex that bad?

These and other doubts filled their minds. In a normal situation, they would not have hesitated for a second, but their minds were in chaos, even their own bodies were deceiving them. The more images of men passed in their heads, the more their penises reacted positively, the opposite happened when images of women passed.

You like men.

You don't like women.

Vaginas are boring.

Penises are delicious.

You like the smell of men.

You like the touch of their skin.

You like their masculinity.

You like to dominate another man.

You like to be dominated by another man.

You love semen.

You love ass.

You love nice pecs.

Muscular bodies are beautiful.

You are gay.

You're gay.

You are gay.

The phrases were repeated over and over again in their heads until they were branded, as if a piece of hot iron had been used, into their psyches.

Already changing their personalities was easier. Just as they did with Ari, they proceeded with the new felines. They implanted doubt in their heads, suggested new ways of having fun, how exciting it was to break the rules, how boring their lives would be if they continued on the path they had planned to follow, the opposite of the new lives they were giving them.

The delight they enjoyed with their role-playing and video game sessions was replaced by wild parties in bars and clubs. Those sodas were replaced by beers and bottles of alcohol. The healthy chats with their friends were replaced by nights of unbridled sex or street fights. Long hours of classes were quickly replaced by equally long sessions in gyms or just wandering the streets. His thoughts began to revolve more around action than contemplation.

While they had implanted some ideas about their respective roles during the stage of sexuality change, it was not until after they had corrupted their minds that they were further developed. While both would be versatile, there was more or less to guide their preferences.

Chris was pretty easy in this regard. Despite having been a virgin, he had always imagined himself as the active person in a relationship, so the AI simply adjusted his parameters a bit. He would still prefer that role, but, if it came to the case of someone who was obviously stronger than him, he could very well switch roles, although he would still prefer to be the one in the driver's seat at the time.

He saw himself in both roles, usually, with men just as beefy as he was. He saw himself in various situations: kissing, biting, playing with another's pectorals, letting himself be groped by others, subjugating other men while he was fucking them with his huge penis, either on the bed, against the wall, on the floor. He also saw himself being penetrated by others, usually bigger, but he was still the one who took the reins. He saw himself sitting on his lover, staring into his eyes with a look that inspired obedience, sometimes he had them strapped or handcuffed to the bed, sometimes by a leash. He was the one who set the pace and depth of penetration.

Deagan, on the other hand, did have to undergo more brainwashing work. Little by little they had to readjust his tastes. Like Chris, he would have a preference for hardened, virile men, preferably, larger than him so that he could be easily dominated. Little by little he was placed in images where he saw himself being used by numerous men, always in a submissive position, either being penetrated or sucking someone's penis. Only once in a while would he act in an active way, usually with men smaller than him or when his mistress on duty wanted to make some changes.

Once they were both fully transformed into their new versions, they were dressed according to their new lives. Both would wear black leather clothes, tight enough to show off the perfection of their bodies. Deagan would wear slightly more revealing clothes, such as a tank-top with translucent black fabric, perfect for showing off her sculpted torso, complete with pierced nipples. Chris, on the other hand, would wear pants that would expose his crotch area, to show off the big package he was carrying, he would also have an equally black, leather cap. Deagan would wear a necklace with a bone-shaped plaque with his name, Chris, a chain closed by a padlock. His ears, eyebrows and nose were pierced with piercings, Chris also gained a ring at the tip of his glans. Both also wore leather bracelets on their wrists.

The jaguar and the puma were able to move again the moment the transformation was over. The first thing they did was to explore their own bodies, to admire them, to feel every millimeter of their new selves. They ran their paws along their arms, felt how their biceps jumped out with immense strength under their fur, paused for a good while massaging their pectorals, feeling each of their abdominal muscles, and even their magnificent necks from which slight grunts of satisfaction emerged. So much attention on their bodies did nothing but provoke a very strong erection, which, due to the revealing of their pants, was evident to all present, but this did not bother them in the least, on the contrary, it ignited the flames of lust.

Both felines approached each other, their snouts almost touched, their breaths mingled, their eyes closed and their tongues intertwined. Chris, by his more dominant nature, guided the jaguar in that passionate kiss. He introduced his tongue completely into the other's mouth cavity, explored every nook and cranny of it, sucked his lover's tongue, also his lips, even biting them a little. Deagan didn't resist at all, he was completely melted by his friend's kiss.

Still united by the kiss, Chris began to remove the jaguar's clothes, he started with his jacket, he threw it to the floor without thinking twice, then he did the same with his shirt, for which they had to break the kiss for a few moments. In turn, he also did the same. Once their torsos were uncovered, he gave her a tight hug, which he took the opportunity to rub his nipples, as well as kiss and even bite the jaguar's neck.

He then laid him gently on the floor, and stretched his arms out to his sides, leaving his belly completely bare, after which He kissed, licked, and bit as much as he wanted. Deagan simply grunted with pleasure. The cougar explored with his muzzle from the jaguar's neck to his waist, paused for a while on his pair of pecs, bit one of the nipples while pinching the other, then alternated between the two.

The passion was still rising, their respective penises had created a huge stain on their pants with all the pre-seminal fluid they had generated. Deagan skillfully released both of their penises from their enclosures, held them for a while in his huge paw and began to make rhythmic movements with his hips. Both had released so much pre that the use of lubricant was unnecessary.

"Chris, I can't take it anymore, just fuck me already,” Deagan pleaded.

"You've turned into such a bitch,” Chris replied. "It will be when I say so."

Deagan continued to moan. The moment he saw the cougar's huge member he wished with all his guts that he would impale him, that he would fuck him so hard he wouldn't be able to walk for a few weeks.

"Well, I'll do one thing,” said Chris. He paused for a moment, released both penises, grabbed Deagan's pants, and, in one motion, pulled them down to his knees, after which he lifted him a little so that his anus was in full view. It was quite pink, very distended, perfect to be fucked relentlessly. Chris licked his lips, then placed his tongue there and began to lick.

A faint roar of pleasure reverberated in that alley. Deagan wriggled with each lick from Chris, who gradually went deeper. His rough tongue gradually traversed the rectum, pausing at each millimeter for a moment to massage the area, push the walls aside, play a little with the spot under which the prostate was located.

After almost five minutes, Chris stuck out his tongue, lowered the jaguar's hips back down to the perfect height and slowly inserted his member inside. Due to the abundant amount of pre-seminal fluid, no lubrication was needed, and thanks to the dilation he had previously performed, his huge penis slipped smoothly inside Deagan's rectum, who was already more than satisfied that, finally, there was a penis inside him.

Chris did not start softly, on the contrary, his onslaught was fast and deep, his cum-laden balls collided with the point where the tail met the ass, meanwhile, Deagan's penis oscillated slightly, bumping from time to time against his sculpted abdomen. The cougar began to pant, but did not slow down the revolutions of his penetrations, the jaguar, on the other hand, was smiling with happiness, enjoying every one of those wild thrusts, of how that huge penis filled every corner of his ass, of how it pushed each of his sphincters apart.

Beads of sweat dripped down Deagan's forehead and chest, he could smell the breath of the one who was penetrating him, just as Chris could smell his own. Deagan reached her hands forward, seeking the cougar's nipples to play with them, Chris moaned at the jaguar's delicate and fine work, so he reciprocated with an acceleration of his penetrations. Afterwards, he leaned forward a bit to kiss him, as well as bite his neck again, this time, much harder. Deagan responded by scratching his broad back.

The cougar paused for a moment, pulled his penis out of the Jaguar's ass, stretched out on the floor and instructed Deagan to lie on his back on top of him, facing forward. Deagan, somewhat confused, obeyed, positioned himself as he said, pointing his anus over Chris's penis, slowly sat on it, always facing forward. Chris took him by the legs, flexed his legs a little for better support and began again to penetrate him wildly. Deagan was amazed at the cougar's strength, as well as his resourcefulness.

Finally, the climax came, Chris sped up his penetrations, his breathing hitched, a final pressure was felt just behind his penis, indicating that discharge was imminent, so, with all he could, he rammed the jaguar on top of him one last time. His urethra dilated and a jet of semen escaped from inside him, filling Deagan's ass, who enjoyed the warm, thick liquid filling her loins. One discharge was not enough to empty all that feline had accumulated, others followed, perhaps with less volume, but equally profuse.

Deagan, to feel completely fulfilled, began to masturbate himself. He didn't have to wait long, his prostate had been well stimulated, it was just a last push for him to ejaculate as well. As if it were a geyser of milk, so was the discharge of his, it went up high, to precipitate on his belly. Just like Chris, it took several strokes to empty his prostate.

Both felines lay on the alley floor for a few moments to catch their breath. They were exhausted, but happiness was also plastered on their faces. Their ample chests rose and fell with each inhale and exhale. It wasn't until a pair of hands were held out to them that they sat up.

"How are you feeling?" asked Ari.

"Better than ever,” Chris replied.

"I never imagined gay sex could feel this good,” added Deagan.

"And that's just the beginning,” Malachi clarified.

"We can't wait to see what the future holds,” snorted the cougar.

"Well, there will be time for that,” Ari replied. "For now, get dressed, it's time to head back to the barracks."

The way to the bar was quite similar to the one Malachi had indicated to Ari, only with some detours. The reception was similar to that of the saber-toothed tiger, the Boss praised the work done by Ari, as well as welcomed the other two felines. Once the introductions were over, they went downstairs where, like last time, there was a party full of drinks and sex.

It was at that party that the new felines gave free rein to their sexuality. Deagan met a lynx, Chris, a black panther. Both exchanged the roles they had played in the morning when they finished transforming. After those couples, more followed, so many that it would be impossible to list them all.

The next morning, both requested to leave the university, they did not give many explanations, neither to the professors nor to their relatives, who did not take long to call immediately when they learned of their children's decision. Life would not be the same after that moment. Now they would simply do the Boss’ jobs and errands.

Over time, the disappearances in the city began to decrease, the surviving gangs had already fully recovered from the war they had had a few months ago, the city was once again breathing calmly.

On the other hand, Ari, Malachi, Chris and Deagan organized themselves into a cell within the organization, the saber-toothed tiger was the leader. Due to the great trust they had gained, as well as the success of each of their operations, they reached a very important position within the gang, Ari even became the Boss’ right hand man.

Their routine was similar to that of the majority: they got up in the morning, usually after a night of intense sex, had a strong breakfast, went to the gym where they stayed for at least an hour, then did the Boss’ errands, if they had nothing, they simply wandered through the alleys of the city, either to go from bar to bar or to do some vandalism. They were happy, they only owed explanations to the Boss, and to top it off, not many, they did not miss their old life at all, not even their families, with whom they had cut off all communication. Their family was now the gang and themselves.
