And they learned to swim

　It is midday in August. Cicadas are buzzing noisily. The midsummer sun was beating down mercilessly, and the soles of the feet were burning hot from standing still by the pool.

　From afar, the sounds of students engaged in club activities on the playground can be heard, as well as the dry thumping of a ball. The deafening sound of cicadas echoed in the air, and the heat so intense that it could create a mirage dominated the place where the supplementary lessons were being held.

　In the midst of all that, three P.E. teachers and three students stood by the pool, facing each other.

　Enduring the direct sunlight that further baked his already tanned skin, Shinya Narita, arms crossed, looked down at his students with a piercing gaze. He is 34 years old, married with a son, standing at 186 cm and weighing 98 kg. In addition to his strong physique, his stern demeanor adds to his intimidation. Sweat was beading on his thick, sun-bleached chest and trickling down his muscular arms, making his sunburned skin shimmer.

"It's a supplementary lesson, so you guys are going to have to work hard together! I'm not letting you go home today until you can swim!!"

　He himself meant it as a joke, but because of his serious face with his mouth set in a straight line and his intimidatingly deep voice, there is probably not a single person in the world who would take it as a joke.

　Standing next to him is Seigo Suzuki, who tries to relax the students as much as possible, keeping his cheerful expression with a fresh smile on his face.

"Don't be scared. Shu, your face is drawn. That was obviously a joke by Narita-sensei…… It's a joke, right Narita-sensei ? Hey! Your face is so scary that the guys are taking you seriously!"

　Suzuki, 26 years old, single, 179 cm, 67 kg, is a man who quietly chats with Narita. His handsome face and toned body naturally attract people to him. Wiping the sweat pouring down his shoulders with his fingers and lightly rotating his wrists as he did his preparatory exercises, he was a somewhat picturesque sight.

　However, even at Suzuki's words, one of the three students, Shu Arisato, cowered his shoulders and could not even reply with a downcast look on his face. He had a slender body and was shrinking as if he was sorry for being here.

　On the other hand, Riku Taketomi, the class president, pushed up his glasses with his fingers and listened to the teachers without losing his serious attitude. He is the type of person who values discipline, and even though it is a supplementary lesson, he does not seem to intend to cut corners.

　On the other hand, another teacher, Kiyoshi Akashi, turns his head somewhat languidly and blurts out, "Why do I have to teach students in the pool on such a hot day?" He is 46 years old, 174 cm, 87 kg, married with two daughters. He was rubbing his beer belly, which was protruding a little, while showing off his thick, well-trained chest plate and wiping off his sweat, somewhat indolently.

"Damn it! If there was a naked lady at the poolside, it would motivate me…… Hmmm?!"

"Akashi-sensei, nowadays, if you show even the slightest crack, you will be exposed on the Internet. Please refrain from such remarks!!"

　Akashi, his mouth covered by a thick palm, looks at Narita, the owner of the palm, with a stern stare, cowering his shoulders and lightly raising both hands in a gesture of understanding. Narita sighed deeply at Akashi's lack of remorse and recrossed his arms.

　Amidst all this, there was one student who was in an unusual state of tension. It was Leo Azumaya. He looked excited, clutching a small bottle in his hand and unable to hide his excitement. His eyes sparkled with anticipation of what was to come.

　Soon, everyone sank into the pool. Under the strong sunlight, the cool water clung comfortably to their skin.

"You guys can always tell me if you're not feeling well, okay?"

　Narita, who frowned at the smell of chlorine that lingered in his nose, asked the students in a low, resonant voice.

"Yes……"

　Shu moves his arms awkwardly in the water as he responds in a small voice. Suzuki looked at him and lightly tapped the surface of the water, encouraging him to relax.

"On such a hot day, it's a hassle to instruct students who can't swim."

　Akashi shook his head in annoyance. However, the look in his eyes was somewhat amused. Having grown up in the countryside, he apparently remembers his boyhood days playing in the river, having been immersed in the cool water in mid-summer.

　While everyone in the pool was adjusting themselves to the water, Leo slowly looked around and quietly extended his finger to the lid of the bottle──.

＊＊＊

　F private high school. At this high school, classes other than the major subjects are elective, and students must choose one of three options: art, music, or physical education. Most students choose according to their interests and strengths, but for Shu Arisato, Leo Azumaya, and Riku Taketomi, the reason for their choice was completely different.

　They have only one purpose. To take classes from a P.E. teacher they admire.

　Nerd and introvert Shu strongly admired the cheerful Suzuki, who was the opposite of Shu. Suzuki's smile was always dazzling, and his words to the students were kind and warm. Shu wished he could be like Suzuki. It was a secret dream for Shu.

　Leo is a punk. However, Leo respects Narita, who takes him seriously and cares about him. While most teachers treated him as a problem child, Narita was different. He did not just yell at him, but confronted him head-on and said to him, 'You can change,' as if he believed him. He was strong, strict, and yet he really cared about Leo. He was the ideal image of a man for Leo.

　Riku's parents had been too strict on him since he was a child. He was forced by his strict parents to excel in grades and follow all the rules. To him, who grew up with such values, the free-spirited Akashi was like a man from another world. He was not concerned about the eyes of those around him, but rather, he behaved openly and lived honestly with his own desires. In Riku's eyes, this was more attractive than anyone he had ever seen before.

　Thus, without hesitation, the three students chose physical education class.

　Some time later, one evening during summer vacation, Leo was walking alone in the downtown area at night.

　Suddenly, a man in a suit with a strong physique approached him.

"Hey, you…… You must be Leo Azumaya……, right?"

　Leo turned around with a dubious look on his face. The man in the suit had a handsome face and a refined appearance, but there was something eerie about him.

"Who are you……?"

　The man replied, smiling.

"Would you believe me if I said I'm an old acquaintance of yours?"

"What? ……You're my acquaintance?"

　Leo frowned. As a punk, he had known a few muscular guys who looked like the guy in front of him, but he didn't recognize him.

"You're lying. I've never met you."

　The man shook his head silently.

"Well, that's a perfectly natural reaction. I am different from the old me, not only in appearance, but in everything."

　What is this guy? Is he crazy? He doesn't know what he's talking about. However, Leo was perplexed, but he could not let the man's words go unheard. The man took out a small bottle from his pocket and held it out to him.

"Here you are. With this, you can swap bodies with anyone you want."

　Leo couldn't help but laugh scornfully.

"You're an old man, but you're out of your mind. That cartoonish story doesn't exist!"

　But the man's eyes were serious.

"I've already used this. That's why 【I】 became who I am now♥"

　The stern face instantly changed to an expression of ecstasy as the big man rubbed his bulging chest through his suit. A shiver runs up Leo's spine. The man's words were supposed to be ridiculous, but the atmosphere was strangely persuasive.

"Wahaha, Leo, it's me! I'm Tanaka! Seriously, thanks to this potion, I've gone from being a fucking punk to this elite office worker with a wife and kids. Well, I know you don't believe me, and you don't have to believe me."

　The man put the small bottle in Leo's hand, saying, 'I'll give this to you anyway.'

"Don't you want to be someone else, too?"

　Leo gulped down his spit at the man's question. The desire that had been locked away in the depths of his heart slowly emerged. I want to be someone else. I want to be him, that strong, beautiful, muscular man──.

＊

　In a corner of the pool, Leo surreptitiously pulled a small bottle from the pocket of his swimming trunks. The contents, shimmering through the glass, were an eerily jet-black liquid. He felt his heart beat faster as he clutched the small bottle.

(With this, I can……)

　With a mixture of anticipation and excitement, he carefully twisted the lid of the small bottle. At that moment──.

"Leo!"

　A sharp voice echoed. It was Shinya Narita. He approached Leo with a grim look on his face as he waded through the water.

"What do you have in your hand……? Give it to me!"

　Leo jerked his shoulders and tried to hide the small bottle as quickly as he could. But his move was slightly too late. Narita's large palm gripped Leo's wrist.

"Hey, let go of my hand!"

　Leo tried to resist, but Narita's power was overwhelming. But as they struggled, a drop of jet-black liquid - just one drop - fell silently into the pool's surface from the mouth of the small bottle that had already been opened. It was at that moment.

──Bwah!

　As if by magic, the pool instantly turned black. The clear water quickly became sticky and turned into a thick, tar-like substance.

"Oh, hey Leo, what the heck is this……!?"

　Immediately after Narita's astonishment, the black surface of the water began to squirm and pulsate as if it were a living creature with a mind of its own. The moment Leo saw that, a look of delight spread across his face.

(I did it! Success!)

　Leo laughed unintentionally. It stirred and moved like a tentacle with a will, rippling around the six of them, entangling their bodies. And then──.

"Nmm……!"

　The sticky black mass attempts to invade the six's bodies with blinding speed.

"Ggh, muuuuh……!"

　A groan of agony echoes all around them. The liquid entered not only through their mouths, but also through their nostrils and pushed down their throats as if it were raping them. They tried to resist the sensation of being fucked deep into their ears, but the more they struggled, the more the liquid took over their bodies.

　As their bodies convulsed violently, they desperately tried to escape while wading through the water, but the sticky liquid continued to entangle their limbs and restrain the six men.

　The more they struggled, the more the slurpy, foreign liquid filled their throats, preventing them from even breathing.

"Stop……!"

　As Narita tried to scream, black mucus poured into the back of his mouth. His throat choked and his lungs burned with agony.

　With eyes wide open, the consciousness of the six rapidly darkened──.

＊

──Silence reigned.

　The cicadas, which had been buzzing loudly just a few minutes earlier, were no longer audible, as if they had never existed in the first place, and the sky was overcast with thick clouds. Although it was supposed to be midsummer, the air was somehow dim and cool.

　Before they knew it, the six men lying by the pool were slowly waking up, one by one.

　The first of the teachers to regain consciousness was Shinya Narita. His eyelids opened heavily, and through his blurred vision he could feel the cold concrete. Next, Seigo Suzuki and Kiyoshi Akashi also slowly woke up, writhing.

　A chill ran down the spines of all three of them at once.

　Something is wrong. The air, the world, it feels strange, as if everything has changed.

"……?"

　Suzuki slowly held his arms and shrank back. Narita also unconsciously rubbed his own shoulder, and Akashi rubbed his stomach, shivering lightly.

　Is it my imagination? ……No, it's not──.

　Slowly looking around their own bodies, they realized that now they were not 【themselves】.

"What…… is this……?"

　Suzuki, who swallowed his saliva with a gulp, muttered brokenly.

　Originally, these three teachers would have been wearing white T-shirts. But now they are not wearing anything on their upper body.

　Not only that. They are P.E. teachers. They have well-trained bodies. Thick chests, strong arms, sturdy legs and hips. Those are their pride and joy.

　And yet──.

　Now, their fingertips confirmed that their bodies were too poor. Their arms were thin and unreliable, with little muscle. Pectoral muscles that did not bulge even when they strained their chests. Thin legs that did not feel as if they belonged to them, even when they stepped firmly on the ground.

"Hey! What happened to us?!"

　Akashi, holding his head, let out a shaky voice. The three teachers looked at each other.

"No way……"

"Is this some kind of a joke……?"

　Their puzzled gazes all turned to one point at once. The men still lying there. They were lying there, not moving slightly, as if asleep. And the teachers gasped. Because──.

　Three 【P.E. teachers】 were there.

＊

"Ummm……?"

　As if in response to the teachers' panicked voices, the three lying students slowly awoke.

　Shu opens his eyelids and looks up at the sky with blurry eyes. Next, Riku shakes his head lightly and clears his throat. Leo, the last to raise his body, exhales low and squints his eyes.

　At first, all three of them had a blank stare. The world was blurred in their vision, and it took them a while to recognize reality. But as their consciousness became clearer, they began to feel uncomfortable.

　Something is different. Their gaze is higher than usual. When they move their arms a little, they feel a weight they've never felt before. Thick chests that they couldn't believe were their own. When they grasped their fingers, they found not bony hands, but large, burly fists. They checked their thick, powerful legs and suddenly their attention drifted to their lower abdomen. There, they discovered a strange sensation that reached down to their own crotches.

"What……?"

　Shu, who had swapped with Suzuki's body, let out a low, pitiful voice. Each of them finally began to understand that their bodies were different now than they had been before.

"You're Leo?!"

　Narita forgot his position as a teacher and sprang toward Leo who was in the form of 【Shinya Narita】. The small bottle that Leo was holding earlier must be the cause of this incident.

"Ugh……!"

　But his arm was easily twisted up by Leo and put around his back. 【Leo Azumaya】 is also muscular to a certain extent, but the difference is obvious when compared to the body of an active P.E. teacher, and he is no match for him in strength. Leo made Narita lie on his face and sat down on Narita's back as if to show him the difference in strength.

"Hey, 【Leo】, what's that attitude towards me, a teacher? Don't do anything that betrays my trust."

　What reached Narita's ears was undoubtedly his own voice. And his tone of voice was just like Narita himself.

"What……?"

"Hehe, the way I was talking earlier, that was really Narita-sensei-like♥♥"

　With a look of ecstasy on his face, Leo crawled his hands on his chest and looked up to the heavens. He has a boner in his speedo-type black swimming trunks with excitement. Confused by that scene, Suzuki and Akashi rushed to Narita's aid.

"Leo!!"

　Two teachers try to pull Leo off Narita, but his muscle-armored body is undaunted.

"Hey, you guys! Help us! You guys would love to get back into your original bodies, wouldn't you?!"

　Akashi, now half-mad and with sweat dripping from his forehead, spat at Shu and Riku. The two students looked at each other. Shu's expression remained thick with confusion.

"It's right…… to help the teachers, isn't it?"

　Riku hesitated for a moment at Shu's words, but then opened his mouth as if he had made up his mind.

"I don't want…… to go back to my original body! What about you? Don't you want to stay in that body?"

　Shu's eyes shook violently at the unexpected response. After a few seconds of silence──, they took the rescue rope that was nearby and tied Suzuki and Akashi's hands and feet with it.

"What?! What are you doing, you guys?! Have you lost your mind?!"

　Akashi flailed about, trying to somehow escape from the restraints.

"Shu, Riku! You're being threatened by Leo, aren't you?! We are on your side! We will protect you. Make the right choice!"

　Suzuki, his face pale, somehow tries to admonish the students. But there was no longer any hesitation on the faces of Shu and Riku.

"……I'm sorry, Suzuki-sensei. I have always envied the uninhibited way of life of Akashi-sensei.I hated myself for having to do whatever my parents told me to do. But now, I'm……"

　Riku muttered and began rubbing his macho yet fat chest and playing with the protruding nipples with his fingers.

"Nmm…… Ohhh……♥"

　Riku's voice is a mixture of pleasure and shame, and Akashi, the original owner of the body, rolls his eyes back.

"What? What are you doing with my body……?!"

　From the time he was a student until he became a teacher, he trained exclusively in judo. But as he got older, he tended to slacken off on his workout routine, which resulted in a sloppy body with thick fat overlaid on muscle.

　Riku played with his body with a look of intoxication on his face. He shoves his hand inside his swimming trunks, strokes the penis hanging between his legs, and sucks on the fingers entwined with honey. He rubbed his beefy body with a lewd expression on his face.

　Akashi himself had never seen such a look of pleasure on his face. Even when having sex with his wife, he could not recall ever seeing such an erotic expression on his face.

"No way…… Riku! Shu!"

　Suzuki called out frantically, but the two of them refused to listen to him. On the contrary, now Shu began to cling to Suzuki's body.

"……Suzuki-sensei♥"

　A rugged hand groped Suzuki's crotch. When the thick, heated fingers touched his genital area, Suzuki involuntarily let out a cry. For Suzuki, who is heterosexual, the feeling of a man's hand rubbing his crotch was so unpleasant that it gave him goosebumps. At the same time, however, he could not suppress the hot and warm sensation of pleasure that welled up inside him.

"Shu, I'm sure you're not the kind of guy who would do something like this…… Come to your senses…… ugh…… ohh!"

　Suzuki's face flushed and he desperately tried to escape the pleasure. The feeling of a man stroking his cock. It's disgusting. That's what his reasoning tells him. And yet, he also thinks it feels good. Suzuki could not help but be confused by these conflicting sensations.

"Hey, 【Shu】, calm down──. Surrender yourself to me……♥"

　A mellow sweet whisper. The soothing tone of Shu's voice caused Suzuki's brain to release a large amount of dopamine. The voice was so pleasant that his brain felt as if it was about to be debauched, causing his eardrums to tremble. At the same time, the feelings of disgust and despair he had felt earlier vanished, and ecstatic feelings began to take over his mind.

　Suzuki leaned back against Shu's large body with spacing out. He was raptly accepting the sensation of the rugged fingertips gently touching him. A different hand from the one that had been stroking his groin embraced his body, and the thick chest adhered to his skin. Immediately, his heart beat fast, and Suzuki felt the blood begin to gather in his lower body.

(Why am I…… hugging a guy……?)

　Earlier, he should have been questioning this bizarre situation, but now he couldn't think of anything. Suzuki unconsciously moved his own face toward Shu's face in front of him.

＊

"Okay, that's it! Shu……, right? And Riku, don't be acting like a perverted old man, come here!"

　The sound of Leo's hand clapping brought everyone present back to their senses. Riku was on the verge of ejaculating from nipple masturbation, and Shu was about to kiss his beloved Suzuki. Both of their faces clouded over for a moment, but they could only be grateful to the devil for bringing about this situation. As they hurriedly gathered in front of Leo, the three of them began to secretly hold a meeting.

"Are you all right, you two?"

　Narita, the only one not bound by ropes, rushed to the two teachers and untied them. The three were now free.

　Should we run away from here? ……No. If we escape from this place and ask someone for help, how can we explain our current situation? They must surely think that we, who look like students, are the ones who have lost our minds.

　Their brains were in chaos, and in this short period of time, none of the three teachers could decide what action to take.

"Hey teachers, how about we make a bet?"

　The teachers, who had been looking down there, just thinking, looked up at the sound of Leo's baritone voice. They look up at the students, who are now completely in the aura of teachers, with their hands on their hips and chests puffed out, as if to show off their strong bodies.

"……Bet?"

　Akashi asked back in a fading voice. In response, Leo twisted his manly face into a sneer.

"The teachers vs. the students. If we ejaculate first, you win, if you ejaculate first, you lose. If any one of you ejaculates within the ten-minute time limit, the swap will be fixed and we will all live in these bodies forever. If you endure ten minutes without ejaculating or, conversely, one of us ejaculates, our bodies will return to normal."

　The teachers were speechless at the outlandish content of the proposal. However, after only a few seconds of silence, Suzuki was the first to speak up.

"Do you really think we would accept such a competition……?! Are you insane?!"

　No wonder Suzuki, who had almost kissed a man earlier, was frightened. Following his words, Narita also got angry and shook his head.

"There's no way we can have a student-teacher relationship and compete over whether or not to ejaculate!!"

"Uh-huh…… Well then, we've won by default, and we'll take your bodies. Hah~, my new family will be waiting for me when I get home. I think it would feel really good to insert my cock into Narita-sensei's wife's pussy~♥"

　Narita couldn't help but shudder with anger at the sight of Leo drooling while holding his plump testicles in his large palms.

＊

"Nn……? Mmmm♥"

　The game between teachers and students began without any choice. Suzuki's opponent is that shy Shu Arisato. It is obvious that I am going to win──.

　Suzuki, who had thought so, had his lips locked with Shu's before he knew it. As their tongues wriggle and saliva is exchanged, his heart aches. Before long, he felt heat gathering in the center of his body.

(What the hell is this ……? Am I…… erect……?)

　Suzuki could not hide his surprise at the changes in his body. However, his rationality was eroded by the excitement that exceeded it and the pleasure that made him want to drown.

"Oh……♥"

　His cock erecting in his swimming trunks. Suzuki rubbed it against Shu's palm and moved his hips. The adolescent's body manufactures sperm in his testicles at a rapid pace even with the slightest excitement, creating a black stain on the most raised part of his swimming trunks.

"Hah……♥ Adult kissing feels good, doesn't it, 【Shu】?"

　Shu whispered this in Suzuki's ear and traced his rows of teeth with his tongue. He entwined his own tongue with Suzuki's, entwining their sticky saliva together. The sensation was like kissing a woman, but the fact that he was kissing his student was an inexpressible source of arousal for Suzuki. The fact that he was kissing a man - and 【his former self】 at that - made his asshole tingle with excitement.

"Hmm……♥"

　In the back of his brain, a warning tone rang out. But Suzuki, loosened up, tangles his own tongue with Shu's in an accepting manner, devouring the feel of it. As soon as he opened his heart, a hard, thick finger reached into his anus and inserted into the tiny hole, trying to widen it.

　One finger, then two, then three…… The sensation of a foreign object gradually entering his rectum is not pain, but a sweet tingle.

(I…… think it feels so good to have my asshole played with……♥)

　His head is getting all messed up. He had never felt so good, even when having sex with a woman. Suzuki has no way to resist because 【Shu Arisato】's body is made to feel pleasure from being fucked by another person.

　But I must endure…… Ten minutes──. Yes, if we just endure for ten minutes, we can all return to our original bodies. Suzuki tried desperately to resist, absorbed in the pleasure so great that he almost fainted. But he did not know. That 【ten minutes】 is too long a time……

　Beside Suzuki, who was letting out a hot breath, was Akashi, whose back was arched to the extreme, jerking and twitching. He was being played with by Riku to every inch of his body, even more than Suzuki, and was being fallen into an endless climaxing hell. His pink cock, clenched in Riku’s large palm, twitched violently, but somehow managed only to overflow with pre-cum. But the testicles hanging below it were going up and down, craving to ejaculate quickly.

"Oh my gosh, stop…… please ♥♥♥"

　Akashi had tears in his unfocused eyes and begged Riku in front of him. He had never shown such humility even to a fellow teacher. But his wish was not heeded. On the contrary, Riku tortured Akashi's body even more intensely.

＊

"Look, Narita-sensei. If you don't hurry up, Suzuki-sensei or Akashi-sensei……, or both of them are going to cum, right? I'm giving you a handicap, so you'll have to make me cum fast, won't you?"

　Narita felt the blood drain from his body as Leo urged him on. And as if all of it was concentrated in his groin, his cock began to erect rapidly. In front of him, Leo was lying on his back as if he had surrendered and was ready to be fucked, the image of himself that he had seen in the mirror every day for the past 34 years. And yet, and yet──.

　My face is flushing. Have I ever had such an erection in my life? I hoped it was just my imagination, but I was sure that my swimming trunks were soaked with the pre-cum.

"What a waste. You have wasted the handicap I have given you. Look, 【Leo】. This is Shinya Narita-sensei's magnificent cock♥ You've always wanted to sniff this one, haven't you?"

　The bulge of a splendidly raised black swimming trunks is pressed against the tip of Narita's nose. The smell of chlorine, mixed with the thick odor of a 34-year-old man, pierced Narita's nostrils. He had never consciously smelled his own crotch before. Although he had been somewhat concerned about his own body odor after a workout, the smell emanating from the 【object】 that was now placed in front of him was on a different level for him.

　He had never imagined that 【his former self】's cock seen through the eyes of another person could be so magnificent, and that the smell of【his former self】's cock smelled so fragrant through the nose of another person……♥

"Nnhaa……♥"

　Narita's knees buckled and he collapsed to the ground. He unconsciously put his hand on the swimming trunks Leo was wearing and slid them down in one motion.

"Whoa……, 【Leo】. You are so bold♥"

　Leo's freed cock emerged from the swimming trunks he was wearing, quivering loudly. The momentum was tremendous, and when it hit the navel and made a sound, it erected toward the heavens. It was a huge cock with perfect thickness and length. The male odor it emitted was very strong because it had been hidden inside a swimming trunks. Every time Narita breathed, the strong smell penetrated his nose and reached his brain, causing him to feel dizzy and lightheaded.

"Nnhaa……♥ Ahh……"

──This is the smell of my cock……♥♥♥

　The steaming cock, combined with the smell of chlorine, already smells like it did after ejaculation. Just smelling the complex combination of ammonia and the smell of like used oil was enough to make his brain go into a state of debauchery.

　Narita found himself mindlessly squeezing the huge cock in front of him. But that's okay. If he squeezed its cock and made Leo ejaculate before the two teachers, they would win……!

　Narita justified himself as he single-mindedly squeezed Leo's cock. He rubbed the corona of the glans penis with his fingers, stimulating the frenulum of prepuce of penis. Each time he was excited by the clear juice that popped out of the tip of Leo’s cock, and he slid his palm so sensitive that he could even feel the unevenness of the blood vessels.

"Oh…… You're good, 【Leo】, keep it up♥"

　Licking his tongue at the lasciviousness of the teacher unfolding before him, Leo gently complimented Narita. Narita's eyes narrowed in fascination at the sound of Leo's sexy voice, and he looked down at the owner of the voice. Thick eyebrows, large eyes, erotic lips. The face he has seen every day. The body he was used to. He never thought that it could be seen so attractive just by seeing it through another person's eyes──.

"Ooooh, I'm cumming♥♥ 【I】, who have lived my life as a diligent P.E. teacher, am gonna cum by getting my cock squeezed by a student~♥♥♥"

　In Narita's palm with blisters, Leo's cock jerked. The cum was released from his cock with great vigor. The amount of cum was so great that it not only puddled on the poolside but also stained Narita's face white as it shot out with a loud splash. The fishy smell enveloped him, but he hurried to check on Suzuki and Akashi. At that moment, the two cocks trembled violently and spat out semen with great force.

＊

"We did it! We won, Leo!!"

　Narita roared at Leo, confident of his victory. It was a close call, but a win is a win. Now we can go back to our bodies. I will not have to lose my life to my students. Relieved, Narita patted his chest and waited for a response from his opponent, the one who had suggested this match. But when Leo finally opened his mouth, what came out was surprising.

"Wow……, great……♥ This is the memory of Narita-sensei…… With this, I can become…… the perfect 【Shinya Narita】……♥♥"

　Leo was in ecstasy, crawling with his cum-covered palms on his own chest, his cock still erect and twitching violently despite the large amount of semen he had released. The tip of his cock was still dripping with cum residue, which seemed to indicate his arousal.

"Hey? Leo, what are you…… talking about? ……AHH♥"

　Narita felt as if his brain was being kneaded by someone else. At the same time, memories of another person flood into his head. The images of 【Leo Azumaya】's 16 years of life poured into Shinya Narita's mind at a furious pace. It was a ritual to completely remake all of him into 【Leo Azumaya】.

"Oh♥ Arghhhh~♥♥♥"

　Unimaginable pleasure. His cock ejaculated again and again in his swimming trunks, and his cum puddled on the side of the pool, running down his thighs. Breathless, Narita somehow managed to muster up the strength to question Leo.

"Leo…… What did you mean by what you said earlier……?"

　Leo, who had finished downloading all of 【Shinya Narita】's memories into his brain, took a breath before anyone else and slowly stood up.

"I'm sorry, Narita-sensei. The bet is all a lie. I just wanted to see you corrupted by pleasure♥ Besides──"

　If either one of the two people swapped by that potion ejaculated, the swap would be fixed forever. In other words, whether I cum or Narita-sensei cum, it was decided from the beginning that we would swap forever♥

　A deep, sweet, masculine whisper. He felt no anger at being cheated. Rather, it was the opposite.

"Oh……♥"

　Narita collapsed on the spot, holding his own cock in his hand. The sexual preference for 【Leo Azumaya】 that had poured into his brain exceeded Shinya Narita's rationality. Their bodies will now remain in this state forever. His body was taken away, his life was taken away, his family was taken away. Such an unrealistic reality aroused him.

＊＊＊

　A few days later, six men were gathered in the air-conditioned P.E. teacher's room. Outside, cicadas were still singing loudly, but their buzzing could be heard only faintly, blocked by the thick curtains. Since it was summer time, the curtains must have been closed to protect them from the sun's rays. Ordinary people would think so, but not in this P.E. teacher's room.

"Nn……♥"

　A sweet, cracked voice echoed through the room, followed by the sound of bodies colliding with each other. The bodies intertwined in the cold room in the middle of the day. Two slender high school students are being fucked by two muscular P.E. teachers. Beside them, Leo, who had become 【Shinya Narita】 in body and soul with a dildo stuck in his asshole, was looking down at the man who had been his former self.

"Ughhhh!!"

　Leo pulled the dildo out with a mighty thud, and his sperm shot out of his erect cock, probably from the pleasure of being released from the pain. His stern face flushed bright red, he let out a thick breath, and he grabbed his buttocks with both palms as he lowered his hips. Leo's wide-open anus is aimed at 【Leo Azumaya】's cock, which is erect as if it were poking the sky. It is a beautiful pink cock that is different from his tanned, dark skin. The quivering glans was dripping dew, waiting for the moment to come.

"Hmm……♥ It feels good, 【Leo】……nmm♥♥"

　As he slowly inserted Narita's hot cock into his asshole, Leo felt indescribable, meditating and biting his lip. Violent pleasure took over every cell in his body. Everywhere felt good, as if his entire body had become a sexual organ. Especially the sweet numbness of the cock rubbing against the intestinal wall, as if it were a direct blow to the brain.

"Ooohhh♥♥ My student's cock is coming into my anus♥♥♥"

"Oh, fuck♥ My cock is melting inside your anus♥♥"

"Hah, boy♥ What do you think, 【Leo】?! How does it feel to pop your cherry in your former asshole?"

"Great♥ I popped my cherry more than a decade ago, but to be able to experience it again…… and to do it with 【my】 asshole, that's awesome♥♥"

　When they first swapped, the teachers were so eager to return to their original bodies. However, the moment it was confirmed that they would be swapped forever, they awakened to their incredible 【Body Swap Fetish】. The mere sight of their former selves on campus causes them to get erections and their pre-cum to overflow, so much so that they wear condoms and chastity belts on their cocks that are still inside their track pants and school pants. Now that even their brains have been swapped out, they are so consumed with gay thoughts that they want to play with their former cocks.

　Even though their bodies have been completely swapped with those of other people, they still have strong memories of their former lives. However, this was a factor that heightened their excitement now that they have become 【Body Swap Fetish】. Being seen by the face of their former selves, being verbally tortured by the voice of their former selves, and having their anus dug by the cock of their former selves. They were totally addicted to the perverse pleasures they could not get in their former lives.

"Wow♥ Excellent 【Leo】! This body is also happy to be taken over by 【me】♥♥"

　Leo was moving his hips up and down violently as he faced the reflection of himself in the mirror just in front of him. Lascivious sounds continued to emanate from his asshole. It felt so good. With the ideal body he has taken over, he plays with the man who is its original owner. Where can there be more pleasure than this? Feeling his balls continue to produce sperm in large quantities, Leo tightened his grip on his new cock and shot his sperm out with a yell.

"Ooooh, Leo, I love you, Leo♥♥♥"
