A cougar, sitting behind a desk and dressed in formal attire, nodded to a slender young shark in front of him, took an already written sheet of paper from a stack on his desk, and began to read: "Discovery of America in the 17th century, industrial revolution 3rd century, French revolution in the 20th century... Look, Mr. Jake, as funny as I find the idea of seeing Napoleon driving his troops in a jeep, I must tell you that you haven't got a single date right, I can't pass your exam with so many big mistakes. "

"Professor Don, I understand that you like accuracy in your exams, but a grade like that would make it very difficult for us members of the swimming group," the shark explained.

"Mr. Jake, you make the situation sound as if I bear some blame for the outcome," the feline replied, raising an eyebrow.

"I have a proposition for you, Professor. Since I've seen you present at several of the team's swimming competitions, how about we make a little bet, you and I?" proposed the student.

"I hear you," said the cougar.

"A race, back and forth in the gym pool. If I win, you'll pass my test and that of my classmates, and if you win..." explained the shark.

"The entire swim team will wear pink swim trunks in competitions," completed the cougar.

"Pink s-slips?" asked the shark, surprised and flushed by the prize the other male had chosen.

"Frightened?" asked Don, smiling a wicked grin.

"N-No! Of course not, I accept!" confirmed Jake with determination.

"Although...On second thought, it seems like too much to win and too little to lose to be a bet I'd be interested in," replied the professor.

The teenager paused to think for a moment and a few seconds later he proposed again, "In addition to what has already been agreed upon, the winner will be able to ask for whatever he wants from the loser, as an extra."

"An extra that will have nothing to do with the swim team or grades in my class, I imagine right?" inquired the cougar.

"That's right sir, the extra will be a purely personal matter between you and me," clarified the shark.

"Perfect, then I accept, when will we compete?" asked the professor.

"This very afternoon, after my team's practice. Coach Drake will be there to make sure the bet is honored," said the student.

The two men shook hands to confirm what they had agreed, the shark left the place smiling and with his chest puffed out with confidence, and the cougar remained seated, his elbows resting on his desk, with a huge grin that showed all his shiny teeth.

**

At six o'clock in the evening, Professor Don walked into the large building that housed the swim team's competition pool. A few sounds echoed through the building, shouts, machinery moving, lockers closing, and wet footsteps. Most of the students had already left or were getting dressed and gathering their things to go home, by the pool there were only two people, a young shark and a dragon of a similar age to the cougar.

The student with whom the feline had spoken a few hours before, was dressed only in a tight black swimsuit, his bare chest denoted an athletic and worked out body, it was not very muscular, but it was clear that in the coming years the young shark could develop a showy abs.

On the other hand, the physical education professor was wearing green shorts and a white short-sleeved shirt. This man did have thick arms, legs and pecs, decorated with huge muscles that were the product of a lifetime of physical training.

As the history teacher approached the waiting couple, the dragon raised his hand in greeting, smiling haughtily.

"How nice to see you around, Don, my student told me about the little wager you two made. I can't wait to see how my star swimmer tears you to shreds," the PE teacher teased.

After greeting the student he had bet with, the feline shook the dragon's hand, squeezing it tightly, "I'm glad you're so confident, why don't we bet something too?" offered the cougar.

"Ha ha! You want to lose twice on the same day? Sounds good to me, ask for whatever you want, I'm not worried, if my guy wins I'll take your parking space for the whole semester," the dragon replied.

"Sounds good to me, Drake, then I'll ask for whatever I want when I win," the other teacher stated.

"Sure, when you win," Drake said, laughing.

The cougar smiled, and headed for the locker room to get ready. Five minutes later he returned to the pool, wearing only a tight blue swimsuit with a white stripe. His muscular body was imposing, and his neat dull yellow fur secretly attracted the attention of the other two males.

"Ha! You're in very good shape, professor, too bad it's not in the right places. Maybe you can be very good at rugby or American soccer, but not at swimming," the dragon sneered.

Immediately, Drake flipped Jake over, turning the young man's body to face the cougar's back, lifted his long, thick shark tail, and gave the shark's firm backside a couple of spanks.

"T-Trainer!" groaned Jake as he was spanked in front of the other male.

"That's what wins races! Strong glutes, not biceps or pecs!" the dragon exclaimed loudly and spanked the swimmer hard again.

"He really has a very nice ass," muttered the feline, as he took a close look at his opponent's butt.

"Don't worry, you're going to be able to see it in front of you for the whole race," Drake assured, letting go of the young shark's tail.

Don smiled and, along with Jake, they both walked over to the showers that were just a few steps away from the pool. After a quick shower, the shark lent the cougar some goggles and, after a brief warm-up, the two jumped into the water.

The warm water embraced the bodies of both males as they positioned themselves against the wall to begin the race. Drake counted down five seconds and shouted loudly to signal the start of the competition.

Immediately, both swimmers shot like arrows off the pool wall, Jake getting the lead thanks to the fins on his body, which made him more aerodynamic against the other male's feline body.

Don swam calmly, with a good pace and without straining, staying behind the young shark but not so far behind. With every movement of his powerful arms, the feline made sure to keep pace with his challenger while avoiding wear and tear.

On the other hand Jake, in the lead, was advancing at full speed, trying to get as much advantage as possible over his teacher. Victory had to be overwhelming, not only to secure his qualifications, but also so that his coach could brag in front of the other man about his swimmers' prowess.

Touching the other end of the pool, the shark shot off again in the opposite direction, his muscles burning just like his head as he watched Don standing alone a few feet behind him with such a relaxed attitude.

Next to the pool, Drake was clenching his fists in excitement. While the dragon knew that his star athlete would easily win the competition, the coach was always proud whenever his swimmers demonstrated the effectiveness of his leadership. Besides, an important local tournament was starting next week and an extra victory, no matter how simple, was always a good way to boost the morale of the whole team.

The goal was near, a few meters from Jake's sight was the wall of the pool, he only had to advance a little more and... and in front of his own nose the cougar passed him. The young shark's heart began to beat fiercely, his opponent had overtaken him and was getting further and further away, his legs were exerting all the strength they could but the feline had already stopped and was waiting for him, catching his breath as his student caught up.

Drake's jaw dropped, and the moment the race was over, all was silent. The two competitors climbed out of the water and before they stood up, the dragon was already beside them.

"What the hell was that all about?" cried Drake.

"Looks like I won..." replied Don, in a calm tone.

"I don't know! I was winning!" groaned Jake.

"You got overconfident!" the dragon chided the boy.

"Of course not! I did everything I could to win!" protested the shark, planting himself firmly in front of his trainer.

"Well, it wasn't much if you were beaten by a brute weightlifter!" the dragon shouted again.

"Screw the bet, I don't want that damn grade anymore!" said the shark, heading for the locker room.

"Ooooh...That's a real sore loser, Jake," muttered the cougar, as he waited with folded arms and a discreet smile.

But before the shark could take a second step, the dragon grabbed him by the wrist, pinning him in place. "Where do you think you're going? When a man makes a bet he keeps it!" shouted Drake in a firm tone.

"He wants the whole team to wear pink swimsuits to competitions, that's crazy!" explained Jake, looking directly at his coach in an attempt to talk some sense into him.

"And I'll see to it that they do what you bet, you'll be responsible for explaining to your teammates why," the dragon replied before releasing the young man.

Without adding another word, the shark retreated grumbling towards the locker room, stomping his feet and clenching his fists.

After a few seconds, when the two teachers were left alone by the pool, the dragon raised an eyebrow as he watched the cougar, who smirked, returning his gaze.

"I'll expect you tonight at nine o'clock at my place. I'm going to put that scaly ass to good use, I promise," Don said before walking off behind the shark, giving Drake a hard spank as he passed him.

When the feline entered the locker room, the shark was waiting for him, already dressed and leaning against his locker, folding his arms and looking unfriendly.

"What are you going to want me to do?" growled Jake.

Don, hearing this, came over smiling and rested his huge hands on the shark's shoulders. "Jake, you need to learn some manners and I'll take care of that. You're going to be my plaything for the rest of the month. I'll send you my home address in a little while, I'll expect you at eight. Be on time," the cougar detailed as he picked up his clothes from his locker.

The shark nodded with a grunt and turned around to go out the other door of the locker room so he wouldn't have to walk in the feline's direction. As Jake passed by the last locker, he punched it, sinking the sheet metal door, then left without a word.

"What energy, it's going to be fun..." said Don, giving a whistle without taking his eyes off the young man's ass as he stormed away.

**

A few hours later, when the sun was barely visible on the horizon, a young shark knocked a couple of times on the door of a nice house in the suburbs. A tall, muscular cougar, carrying a wet towel resting on his shoulders, opened the door and smiled at the sight of him. The shark blushed at the sight of the other male and entered the house, ducking his head to hide his embarrassment.

"You're just in time, I just finished a quick weight lifting session," Don said, greeting his visitor.

"Yeah...You told me to be here at eight," Jake recalled.

"That's right, you did well and I like that, obedient boys go a long way," the cougar replied, before giving his student a spanking.

"So...now what?" asked the shark.

"Strip and wait for me here, we're going to start by teaching you a lesson," the feline said before leaving the room.

Jake snorted, looked around and, after analyzing the situation he had just gotten himself into, began to undress until he was completely naked.

When Don returned to the room, his guest was standing and covering his genitals with his hands, just as he had come into the world. The cougar sat down in a huge, comfortable armchair, and patted his leg a couple of times, indicating to the shark to sit on it.

The shark again obeyed and, rather carefully and embarrassedly, sat on his teacher's leg.

"Good boy. Now lie down on your stomach," the feline indicated.

Jake swallowed saliva and leaned back against Don's muscular legs. The shark's flaccid penis dangled, touching the tip of his glans to his teacher's shorts, his legs trembling as he tried to look back to see what the other male wanted to do.

Don rested his hand on the shark's ass, squeezing and fiddling with the swimmer's perfect buttocks. Then, the feline lifted the shark's long tail, sucked one of his fingers and plunged it into the anus of the male who was trembling submissively on his legs.

"Wow...that's tight. Haven't you ever had it up your ass?" the cougar asked, sharply and bluntly.

With a weak moan, Jake involuntarily responded to his teacher, who twirled his finger around, pulled it out, and pushed it back into his anus. It was known that the shark had had a couple of experiences with other men, but always as a top, no one had ever been able to touch his rear end.

A few minutes later, Don pulled his finger out from inside his new toy, raised his open hand and brought it down hard, making it impact against the shark's firm buttocks. Jake gasped and jumped in surprise at the hard spanking he received.

"What the hell are you doing!" protested the young swimmer.

Another hard spanking made the shark squeal, "I'm educating you, it's part of my job, you cheating, sore loser kid," Don replied before spanking his student again.

"Would you stop!"groaned the shark, swinging his arms back in an attempt to stop the other male without success.

The feline's open palm landed again on the swimmer's skin, making it sound followed by a masculine squeal. Don repeated the spank, ignoring his student's screams, until the shark's backside was completely red.

When the teacher finished with Jake, the young man slowly stood up. His legs were shaking and he couldn't straighten them, he was still groaning from the burning he felt, and his pride was deeply wounded.
"Looks like you quite liked the treatment," Don said.

"Of course not!" exclaimed Jake, turning around to face the cougar.

"You sure? So...what's this?" asked the professor, pointing to a patch of clear liquid on the fur on his leg.

"I-I don't know, sweat maybe...You said you were working out before I got here," excused the shark.

"And that's from exercise too?" asked Don again, pointing to the throbbing, dripping erection the young man had between his legs.

Jake opened his eyes wide at the sight of his rock-hard penis. The teenager hastily turned around to hide his member and his face from the other male, and let out a grunt.

The feline grinned, got up from the couch, and grabbed a handful of underwear he had brought a good while ago, stretching it out in front of his student to show it off. They were three jockstraps, one leopard, one tiger, and one pink.

"Put one on, whichever one you like best," Don offered his guest.

With his hand trembling slightly, the shark grabbed the garment that had the colors that mimicked a leopard's fur and put them on. The garment made his ass look a little more raised, while the front could barely contain the young shark's erection, quickly dampening the fabric with the clear juice dripping from Jake's penis.

"Stand against the wall and spread your legs," the feline ordered.

Jake obeyed and, a few seconds later, the 'click' of a cell phone camera was heard, blushing.

Don instructed the shark to get into several different positions while the professor photographed him. They then repeated similar positions with the tiger jockstrap and the pink one, getting more than a dozen provocative and compromising photos of the shark.

"You look great. Put this on too," the cougar said, smiling and holding a black blindfold up to his student.

"What's this for?" asked Jake.

"To cover your eyes, it's part of the game," explained Don.

The shark obeyed and covered his eyes with the black cloth, leaving him completely blind and at the mercy of the other male.

Don cuffed his guest's wrists and spun him around a couple of times, enjoying the young swimmer's body. Then he settled him against the wall and plunged a couple of fingers into the shark's anus.

"It really is unreal how tight your ass is, it's going to be a pleasure to stretch it," the cougar murmured in Jake's ear.

The shark heard the sound of a cell phone app. "I'll be back in a moment, get ready to be no longer a virgin," Don said, before leaving the room.

A moment later, Jake felt a pair of strong hands grab his hips, two thumbs stretched his buttocks, and a hot wet glans kissed his anus. The shark groaned as he gritted his teeth as he felt the other male push his way inside him, until a powerful onslaught caused the young swimmer to let out a yelp before he felt a pair of huge testicles slap his from behind.

"How does that ass feel?" asked Don.

"It's too tight, need to give it more practice until it softens up," replied another male voice.

"T-Trainer?" squealed Jake, still standing with his hands tied and blindfold on.

"Hush, boy, I'm testing what it feels like to fuck a loser's ass, a sore loser," growled the dragon, before continuing to penetrate the shark.

As Drake punished his star swimmer, Don positioned himself behind the scaly and smacked his buttocks a couple of times with his feline penis. "You spread your legs, I have to give you a lesson in humility too," the cougar ordered the other male.

"B-But...Are you going to fuck me while I'm punishing the boy?" moaned the dragon, still with his penis buried in the other man's ass.

"Of course I am! You're both terrible sports, all competitors are respected, before and after the competition," the cougar explained, then rammed the dragon hard.

"Ow!" cried Drake as he felt the full length of the feline enter his experienced anus.

"Wow, what a nice ass!" growled Don, the moment his balls slammed against the dragon's buttocks.

"What the hell is going on?" groaned Jake, unable to remove the blindfold covering his eyes, thanks to the huge, scaly body of his trainer now pressing him against the wall.

"Don't worry, I'm just busting your trainer's ass, you just keep enjoying the cock you're getting," the feline said.
Drake gritted his teeth, trying to ignore the jerky movements of muscular cougar who was tightly restrained behind him, and returned his focus to the swimmer's ass which already felt more dilated and wet from the male juices slowly lubricating his insides.

A few minutes later, the dragon moaned and snorted, ejaculating inside the shark several jets of hot semen into the young man's depths. Immediately, without giving you a second to recover, Don separated Drake from the shark and took the trainer's place in Jake's ass, plunging his feline penis into that warm cavern and bathing his phallus with the other male's seed.

"Don't just stand there, Drake, it's your turn to give the boy some affection. So hurry up and suck Jake's cock," Don ordered, imposing his natural dominance on the others.

The dragon responded with a grunt, and settled in front of his swimmer, kneeling in front of Jake's dripping cock, taking the shark's phallus with his tongue and devouring it with his maw, making the glans touch the throat while the rest rested on the reptile's tongue.

Don smiled as he watched the obedient dragon follow his directions, then slapped the shark's ribs a couple of times, and said, "Now it's my turn."

Jake ignored the cougar's words, as he enjoyed being penetrated and sucked at the same time. Only a feminine moan came from the shark's snout as he felt inside him as the warm feline semen spread and mingled with the load his trainer had previously left him.

With a wet and dirty sound, the cougar disengaged from the shark's ass, pulling his now relaxed penis out of the young swimmer's swollen, reddened, and still open anus. Two men's semen dripped from Jake's loins and fell sonorously to the floor, forming a small, thick puddle.

Don licked his lips, picked up his cell phone again and photographed that job well done, as the dragon continued to fellate the other male whose legs were trembling thanks to all the attention his no-longer-virgin ass had received.

Jake, still unable to see, felt two thick fingers plunge without warning into his sensitive loins, making the young shark's legs tremble as he moaned and unloaded his manly and abundant juice into the dragon's mouth, who gladly accepted the warm liquid and swallowed it without hesitation.

Drake pulled back panting, withdrawing his star athlete's penis while a trickle of semen still connected the tip of the shark's glans to his lips, generating another scene for an ideal photo that the feline didn't hesitate to take.

Don removed Jake's handcuffs and blindfold, and offered a couple of towels to his guests. "It's time for dinner now, let's have something to eat and drink before round two," the cougar offered.

"Round two?" stammered the shark.

"You've never had sex with a feline?" asked the cougar, smirking.

"No..." replied the shark worriedly.

"Well... let's just say the night hasn't started yet. Besides, you've yet to get your revenge on the dragon, I assure you that ass is a delight," Don assured, winking.

**

A week later, all the members of Jake's team were standing firmly at the side of the pool, wearing pink swimsuits, arousing some laughter and teasing among the onlookers.

"And here's the home team, who have decided to join the breast cancer campaign and wear pink, the signature color of said campaign..." explained the event's narrator.

Sitting in the stands were Drake and Don, watching the competition with enthusiasm, clapping and pumping their fists as the swimmers were introduced.

Jake turned his gaze for a moment to his teacher, and Don made an obscene gesture with two of his fingers and his tongue. The young shark's face flushed for a second before the starting gun sounded and everyone dove into the water. A long-awaited reward awaited the shark that very night at the hands of the cougar, win or lose.
