The Life Swap Game (Pixiv Fanbox)

(Alright, I guess it's time to actually sleep~)

　The bedroom was pitch black with the lights off. Koichi Fujiwara, a third-year high school student, placed the smartphone he'd been holding on his pillow, stretched widely, and let out a small groan.

　His already large body took up even more space, causing the steel pipe bed to creak and groan.

　The clock had just passed ten at night, but with early morning rugby practice scheduled again tomorrow, he needed to get to sleep as soon as possible to recover his stamina. Though he spent every day running around the field and colliding with other guys, it wasn't painful for Koichi, who loved physical activity.

　This year, he aimed to reach the pinnacle of rugby: qualifying for the Hanazono Tournament. With the current team members, it might just be possible.

　In a daze, Koichi was dozing off when suddenly a notification sound came from his smartphone.

'Congratulations! You have been selected as an opponent in The Life Swap Game.'

"……What the hell?"

　The smartphone screen displayed an incomprehensible message. No matter how much he tapped the screen, it remained frozen, unresponsive. Feeling uneasy, he pressed the power button, but the device wouldn't shut off.

　The room was shrouded in pitch blackness, making it feel like he'd wandered into a horror movie.

＊＊＊

　Looking ahead, to the sides, behind…… nothing but white. Nothing there, and no one around. To make matters worse, looking down, Koichi was completely naked. Thanks to all his intense training, he had a bulging chest and defined abs. Thick legs, and a huge, fully erect cock that was way too big for a high schooler.

　He'd had these kinds of baffling dreams before, and this was probably just another one of them.

　As he tried to calm himself with that thought, suddenly, a short distance away from Koichi, his father, Shinji Fujiwara, appeared.

"Huh? Dad?!"

"……Koichi?! What the hell is going on here?! And what's more, both of us are completely naked?!"

　Just as Shinji said, he too, like Koichi, wasn't wearing any clothes—not even underwear. Though his middle-aged belly made his waist a bit loose, the muscular physique he'd built through constant training as a firefighter was impressive. And then there was that thick cock, even more imposing than Koichi's. Koichi frantically looked away, but Shinji seemed completely unfazed. Maybe working in such a manly environment meant he felt no shame about being naked.

　It seemed Shinji also had no clue what was happening. As Koichi and his father scratched their heads over this baffling situation, two more men appeared further away.

"Hey……, You're Mitsuru, aren't you?!"

　Mitsuru Isobe is a classmate of Koichi's at high school. Though they're in the same class and see each other every day, Koichi has never once had a proper conversation with him. They've exchanged greetings before, but Mitsuru's voice was always so soft that Koichi could never quite make out what he said.

　Incidentally, despite being nearly a head shorter than Koichi, Mitsuru was quite obese, likely due to his weight. Standing even further back from him was a middle-aged man who bore a strong resemblance to Mitsuru and was also overweight.

　Was this Mitsuru's father? Could Mitsuru be the source of this bizarre situation? As Koichi turned his gaze toward Mitsuru, both Mitsuru and the man who seemed to be his father grinned, their smiles thin and unsettling. Mitsuru is the culprit! Just as Koichi, convinced, opened his mouth to speak, a board resembling a giant Sugoroku (a Japanese roll-and-move board game) appeared at his feet, and a voice from somewhere resonated directly inside his head. A shrill, ear-piercingly unpleasant voice, yet one that carried an overbearing authority impossible to resist.

"You will now participate in The Life Swap Game."

　Suddenly, a screen resembling a game status display appeared above Koichi and the other three.

『Koichi Fujiwara　Occupation: Third-Yeah rugby player at U High School　Height: 185cm　Weight: 98kg　Traits: Has a girlfriend』

『Shinji Fujiwara　Occupation: Firefighter (Fire Sergeant)　Height: 187cm　Weight: 112kg　Traits: Strong Sex Drive, Large penis』

『Mitsuru Isobe　Occupation: Third-year gay student at U High School　Height: 162cm　Weight: 105kg　Traits: Introverted, Body Swap Fetish』

『Morihiko Isobe　Occupation: Construction worker　Height: 165cm　Weight: 110kg　Traits: Bisexual, Divorced once, Overprotective』

　Not only Koichi, but it seemed Shinji's body had also stopped obeying him. The four of them were each moved onto one of four boards that had appeared on the ground. The squares were decorated with illustrations and text, but the letters were absurdly huge and hard to read. Just as they stood there, utterly bewildered, a giant dice fell from above. Koichi caught it reflexively. It was about the size of a small refrigerator, but it wasn't heavy.

'Alright then, let The Life Swap Game begin~~!!'

　A huge firework burst into the empty, void sky. What the hell is this guy talking about? Who'd listen to some weirdo like this? Koichi resolved this in his heart, but contrary to his intentions, his hands moved of their own accord, and the dice rolled onto the ground.

【Koichi Fujiwara, Move Three Spaces】

"Oh……, my legs are moving on their own……!"

　Even as he tried to resist, Koichi’s feet forced him forward. One step, two steps, three steps. And the words written on the space where he stopped read──.

【Mitsuru Isobe. First ejaculation in seventh grade. Inherited his father's, a short, tight uncircumcised cock to smegma buildup】

　Seeing such words, Koichi could only stare blankly. But the next instant, his groin began to throb violently. Koichi wasn't uncircumcised. In fact, his cock was larger than the average Japanese man's. Yet, before his eyes, it began to shrink rapidly, the glans covered by the foreskin. His balls shrank along with it. Witnessing a part of his own body change at such a terrifying speed, Koichi could only feel dread. Eventually, the movement ceased. When he placed his hand on his crotch, what he found was a tiny, thumb-sized, uncircumcised cock. It was completely different from what had been there moments before. Even more terrifying, a tingling sensation began to stir beneath the skin, gradually swelling……, until it pierced through Koichi's skull.

"Ugh……!!!!"

──SPLAT!!! BURRRRRRRR!!!

　Koichi couldn't help but throw his massive body back in shock. An orgasm even stronger than his first time with his girlfriend. The unprecedented pleasure made his hips feel like they were about to shatter. And with that momentum, a massive load of semen was unleashed inside his skin. His now-shrunken glans twitched and pulsed violently within the skin, the ejaculation refusing to stop. Thick, milky white fluid oozed out from the tightly constricted opening of the foreskin. Koichi's mind went completely blank, and all strength drained from his body.

＊

'Next up, Shinji Fujiwara's turn'

　A cold voice echoed from above. Despite his resistance, Shinji's hands were forced to grip the enormous dice. His powerful arms obeyed not his will, lifting and flinging the dice as if he were a puppet on strings.

【Shinji Fujiwara moves five spaces forward】

　The dice came to a stop right before Shinji's eyes. In that instant, his body began moving of its own accord, just as it had with Koichi, and he took five heavy steps forward.

【Morihiko Isobe. Born with single eyelids and a villainous face that never changed as he grew up. A fat man with strong body odor】

"Wh-what……!"

　The moment he uttered his gasp of shock, Shinji's face began to warp grotesquely. Fat settled on his once-chiseled cheeks and jawline, his skin became rough, his nose bridge flattened and spread. His sharp eyebrows became a messy tangle, his lips dried out and swelled into a puffy, swollen mass.

"My face! My faceeeee!!!"

　Even that scream sounded somehow hollow from his mouth as it distorted. Shinji's manly face, admired not only by women but by men too, was transforming into a pitifully pathetic old man's face. His nostrils flared, and greasy sweat broke out on his forehead.

"Nooo……! Stop it!! Turn me back!!"

　Along with his voice of despair, Shinji's vocal cords began changing too. His low, deep voice was replaced by an unpleasant, coarse, raspy sound.

"D-Dad……"

　He was my dad……, the father I had always respected and loved…… The fact that his face had become that of an ugly stranger was something Koichi, his son, simply couldn't accept. To make matters worse, the smell of sweat and body odor was stronger than ever before. Just looking at him now made a deep sense of disgust well up inside Koichi.

'Next up──Mitsuru Isobe's turn.'

　Unlike Koichi and Shinji, Mitsuru showed not the slightest resistance to the voice from above. Instead, as if he'd been waiting for it, he held out both hands and caught the dice that fell from above.

"Hehehe…… Here it comes, here it comes, HERE IT IS!!!"

　Mitsuru swung his arm back with all his might and hurled the dice.

【Mitsuru Isobe, move six spaces】

　The moment he saw the text that appeared where his piece landed, Mitsuru's face contorted with pure joy.

【Koichi Fujiwara. Exceptional athletic ability, became a regular on the rugby team in his first year of high school. A powerfully built physique that captivates everyone】

"Wooooohoooooo! This is the best!!!"

　Mitsuru's screaming body shook violently. At 162 cm tall and weighing 105 kg, his physique could only be described as obese under normal circumstances. His flesh, covered in loose fat, began to tremble as if pulsing intensely.

　His flabby, sagging belly tightened as if being forced inward. Powerful veins stood out on his thick, muscle-packed arms. His shoulders broadened dramatically, and with a creaking sound from his spine, his height increased.

"Ugh, ahhhhhhh…… This…… this feeling…… I can’t take it anymore♥♥"

　Instantly, what appeared there was──a muscular body identical to Koichi's, honed as a rugby player: 185 cm tall, weighing 98 kg. His chest was thick like armor, his thigh muscles bulging. Droplets of sweat glistened on his taut legs, almost beautiful to behold. His log-like arms and legs were virile, sharpened to the tips of his nails.

"Haa…… haa……, heehee……♥ This is…… the Koichi's body……!!"

　Mitsuru's expression was utterly intoxicated. He caressed the body, identical to Koichi's, as if confirming it with his fingertips, exhaling in ecstasy.

"It's amazing……! This body, it's so cool……! You really are the best, Koichi♥♥"

　Excited, Mitsuru continued to fondle his chest and stomach lovingly, his small, still-uncircumcised cock twitching and trembling. Mitsuru's eyes glistened with desire as his fingertips persistently traced the contours of 【Koichi Fujiwara】's body.

"Haa…… haa……, yes…… that's it! More…… I'm going to make Koichi's body mine……♥"

　For the first time in his life, Koichi felt the emotion called 【fear】. Could this really be happening? When he was a kid, he'd read a manga where the protagonist got his body swapped with an enemy. Back then, he'd just been excited to see how the story unfolded…… but actually experiencing it himself? It was so eerie and terrifying……!

"Hey! You there, kid!! What the hell did you do to us?!"

　Shinji, his voice completely altered, roared. But Mitsuru paid no attention, merely trembling with rapture over his small penis. With that, the only option left was to seek answers from the man who seemed to be Mitsuru's father.

"Hehe……! I'm Morihiko Isobe, Mitsuru's father. Actually…… Mitsuru and I applied for a game called 【The Life Swap Game】."

(The Life Swap Game……?)

"What exactly is The Life Swap Game……? Well, to put it simply, it's this amazing game where you experience a board game like this and can swap not just bodies, but entire lives with the person we choose."

　Morihiko grinned broadly, gazing fondly at Mitsuru's transformed appearance. It wasn't just a father's affection; the look in his eyes clearly conveyed an abnormal obsession.

"Mitsuru's all grown up now, huh. You're a high schooler already. You've gotten a bit cheeky lately, but you're still my pride and joy. You used to be short and chubby like me, but I'm so happy you've grown into such a fine young man."

"Hah…… hah…… Daddy, stop it…… This body is Koichi’s body now……! I don’t look anything like Daddy……♥"

　Mitsuru flushed, letting out a hot sigh as he pleaded with his father. Yet his tone held a certain intoxicated sweetness.

"Oh…… that's right. You've taken over Koichi's body now, haven't you? Hehe……! But Mitsuru is my pride and joy, you know. Just like me, you're brilliant, adorable, and a model student. That's why I decided to be reborn as a 【Daddy】 worthy of Mitsuru. Swapping the ideal father figure and life? Isn't that just the best?!"

　Hearing Morihiko's words, Mitsuru narrowed his eyes dreamily and caressed his own body. Seeing this, a chill ran down Koichi's spine. A look of ecstasy spread across Mitsuru's face, his eyes seeming to hold a hint of madness.

'Next──Morihiko Isobe's turn.'

　The moment the voice fell, the dice settled in Morihiko's hand.

　The dice flew through the air and rolled onto the board.

【Morihiko Isobe, move four spaces】

　The text that appeared where he stopped read──

【Shinji Fujiwara. Became a firefighter after graduating university. Powerfully built. Broad chest and shoulders, brimming with energy】

"Oh…… ohhhhh……♥♥"

　A bestial groan escaped Morihiko's throat. Height: 165 cm. Weight: 110 kg. The physique of a construction worker—fat layered over thick muscle—began to bulge and undulate.

　The excess flesh on his belly vanished as if crushed, replaced by defined rectus abdominis muscles. His chest grew thicker and thicker, his shoulders broadening. Muscles like iron plates clung to his thighs, and his upper arms swelled to the girth of a woman's waist.

"Guh…… hehehe!…… Yesss……♥"

　Morihiko's voice transformed into a low, crawling tone. Though his face remained unchanged, the alteration below his neck gave him a voice closer to Shinji's. The muscular physique of 【Shinji Fujiwara】—honed through relentless training to protect the townspeople—had been stolen wholesale by Morihiko.

"Huh…… Huh huh! This is it……! This is what I've been craving……♥♥"

　Overcome with excitement, Morihiko clutched his sweat-soaked body, panting heavily as he writhed in ecstasy.

"The body of an active firefighter! This is truly the physique worthy of Mitsuru's daddy, the ultimate man's body……♥ Ahahahaha!!"

　Like Mitsuru, Morihiko's uncircumcised cock twitched rapidly, a transparent thread stretching from beneath its skin. Exposed to the heat and pheromones radiating from 【Shinji Fujiwara】's skin, Morihiko too had become utterly captivated.

＊

'Alright, it's time for the fun, fun second round of the game~♪'

　Mercilessly, the dice rolled again, landing on the ground as Koichi's body moved across the squares.

【Mitsuru Isobe's Fetish. Influenced by a manga he read in fourth grade, he became aroused by situations where men swap bodies.】

"Wh-what the hell?! Ahe……♥"

　Suddenly, Koichi's brain felt pleasantly numb, like it was being kneaded by a large hand or gently massaged. The memory that surfaced was the same episode from that super famous shonen manga Koichi had recalled earlier. The one where the protagonist and the enemy swap bodies due to the enemy's mysterious ability. At this moment, a fiercely passionate lust for the act of male-to-male body swapping surged within Koichi. Excited, his groin—which had just swapped with Mitsuru's—grew hot.

"Koichi, are you okay?!"

　A gruff voice came from right beside him, but he was anything but okay. The bizarre situation now mirrored that manga's plot perfectly. Someone else had copied a part of his body, while he'd been pasted with a part of someone else's body he didn't want. Just moments ago, this situation had felt utterly creepy, but now it filled him with an uncontrollable excitement. Not just his cock—he wanted to swap his entire body for Mitsuru's. Unable to suppress this insane desire, Koichi crouched down on the spot.

'Next up──Shinji Fujiwara’s turn.'

"S-stop it alreadyyyy! I don't want thisssss!!"

"Fuh-huh, gotcha. Hehehehe♥"

　Koichi clutched his head, torn between desire and reason, while the game progressed smoothly. By the second round, Shinji's body had become exactly like Morihiko's, and Mitsuru's face was identical to Koichi's. And Morihiko's cock had become exactly like Shinji's. Shinji and Mitsuru were now, except for their cocks, identical copies of 【Morihiko Isobe】 and 【Koichi Fujiwara】. Seeing Mitsuru, who had become almost identical to himself except for one part, and his father, who was now just a short, fat man with a huge cock, made Koichi's small, uncircumcised cock ache even more. Koichi wrapped both hands around his cock, pulled back the skin, and began rubbing. A pungent smell of smegma began wafting from under Koichi's foreskin.

"Stop it……! Koichi!! Don't touch that filthy cock!!"

　Shinji's anguished cries no longer reach Koichi's ears. Before he knew it, the turn had entered its third round. The dice that fell hit Koichi's body, still frantically rubbing his cock, and rolled onto the ground. His massive body moved across the grid while jerking off.

【Jackpot~♪ One-shot reversal, full-body swap!! To a pig-like ugly face~, the short and chubby body of Mitsuru Isobe♥】

"Nnnghhhhhhh♥♥♥"

　Koichi's thick, muscular body—other than his cock, the ideal male form—rapidly shrank. His gaze dropped lower and lower. His height, once 185 cm, became 162 cm. The tightly packed muscles transformed into fat. To make matters worse, his face instantly deformed into a pig-like face. The figure any man would envy instantly transformed into a chubby, ugly man. The flesh on his face jiggled and shook, and his jawline became double-chinned.

"Ugh…… heh heh……♥"

　A sound like a pig's squeal escaped Koichi's mouth. His mind was in chaos. He couldn't comprehend what had happened to his body, but pleasure raced through him like lightning.

"Haa…… haa…… It feels so good……♥♥"

　As if to bring Koichi back to reality, a mirror appeared before him, reflecting his entire body. What was reflected was his own hideous, pitifully grotesque form. Yet for Koichi, now awakened to a fetish for 【Body Swap】, this sight stirred an unbearably sexual excitement.

"Oh my gosh……! This is what I look like now♥ So fat and ugly…… and my body stinks to high heaven♥♥"

　Koichi drooled as he played with the foreskin of his cock. Koichi's mind and 【Mitsuru Isobe】's body were blending together at an alarming speed, growing increasingly sensitive. Pulling his nipple made his entire chest twitch in response. Unable to withstand the stimulation, his cock swelled even larger.

"Ahe……♥ Oho……♥"

'Come on, come on! Only three left! Everyone~! Ready for the final push?!'

　Prompted by the voice echoing down from the heavens, the third round continued. Shinji's cock transformed to look exactly like Morihiko's, and Mitsuru's cock became identical to Koichi's. Finally, it was Morihiko's turn.

【The face of Shinji Fujiwara, the sexy firefighter everyone admires】

"W-with this, I too will become the perfect, ideal daddy……♥♥"

　Morihiko's villainous face contorts grotesquely. The thick layer of fat covering his face melts away, his nose becoming more defined. His jawline sharpens, and beneath his bold eyebrows, eyes regain their sparkle. Morihiko's features rapidly reshape…… until his face is replaced by that of 【Shinji Fujiwara】.

"Yeahhh……!! So cool~~♥ This is the face of my ideal daddy♥"

　Mitsuru's excitement made his breath come in gasps. Praised by his son, Morihiko's now rugged face broke into a goofy grin, his massive cock erect and twitching as it pointed skyward.

"Wow, wow, wow♥ This is my face, my body, my cock♥♥ From today on, I can live as such a cool dad♥ Ahem……, I'm 【Shinji Fujiwara】. I'm a firefighter protecting the town's safety! And my 【son】 is……"

"I'm 【Koichi Fujiwara】, I play rugby in high school! My dream is to become a firefighter like my respected 【dad】 someday!!"

"Hehehe……! This is the first time Mitsuru has ever said he respects me……, daddy's so touched!! Looks like we're going to have a great life from now on, Mitsuru…… no, 【Koichi】♥"

　They were about to abandon the lives of 【Mitsuru Isobe】 and 【Morihiko Isobe】, starting anew as 【Koichi Fujiwara】 and 【Shinji Fujiwara】. 'Our bodies had been taken over, and soon our very lives would likely be stolen too.' Lost in such thoughts, Koichi suddenly realized his own small, uncircumcised cock had reached its limit.

"I'm cumming♥ I'm gonna cum with Mitsuru's body♥♥"

──Spuuurt! Throob!! Drip drip!!!

　Sperm shot from Koichi's crotch, forming a white puddle. Witnessing this, a massive load also erupted from Shinji's uncircumcised cock. As a result of their bodies swapping, he—now using the brain of 【Morihiko Isobe】—seemed to have developed an intense lust for the phenomenon of men swapping bodies.

'With all four of us finishing, the life swap is complete! Game over~♪'

　The board that had been laid on the ground had vanished without anyone noticing. The Fujiwara father and son wore vacant expressions, still caught in the afterglow of their ejaculation. In stark contrast, the Isobe father and son, excited by their new bodies, were frantically jerking off their cocks.

"Guheh-heh♥ 【Dad】, let's enjoy our new lives to the fullest, huh?"

"Of course, 【Koichi】. Let's enjoy ourselves in these reborn bodies!! We've even got a new mom now♥"

　The two, who had taken over others' bodies through a suspicious game, wore happy yet vulgar grins.

＊＊＊

"How's that, Koichi? Feeling my thick, circumcised cock filling your ass up nice and tight? I worked your asshole nice and loose before swapping bodies with Mitsuru, so it's pretty damn good, huh?"

"Ugh……♥ That's disgusting…… You're way too gross, old man!! Pull it out already, we're men, dammit!"

"Heh heh♥ You say that, but it seems your body's being honest, 【Mitsuru】…… Your asshole's squeezing my cock so tight♥ Feels good for me too……♥ Getting to have intense sex with my beloved 【MItsuru】♥"

　【Shinji Fujiwara】's muscular body covered the small, chubby frame of 【Mitsuru Isobe】 as his thick cock plunged in and out, sucked deep into the loosened, stretched opening. The two engaged in beastly copulation, thrusting wildly in the Fujiwara family's living room.

"Stop…… stop it……♥ Neither me nor my dad…… would ever submit to perverted homo bastards like you!!"

　Koichi struggled desperately, but 【Mitsuru Isobe】's body wouldn't obey him. Worse still, deep within Koichi's mind, the 【Body Swap】 fetish had been complete implanted. He had been stained with a perverted taste, finding pleasure in being violated by a man who had taken over another's body. As a result, his body no longer rejected the cock of the man who now bore his father's form— 【Shinji Fujiwara】—but instead moved to welcome it willingly.

"Hehehe…… You're amazing, 【Mitsuru】…… Seeing you resist with my beloved son's body just gets me so damn excited, you know? Hey right, 【Koichi】?"

"Yeah, 【Dad】♥ Fucking this old man who looks like 【Daddy】 in this new body feels way better than shoving my cock into my girlfriend pussy♥♥♥"

　Mitsuru, who had taken over the muscular body of 【Koichi Fujiwara】, thrust his hips wildly, his handsome face contorted in slovenly pleasure. The one getting his asshole pounded was Shinji, Koichi's father and the original owner of that body. Shinji's mind was filled with two conflicting emotions—rage and pleasure—and he couldn't think straight anymore.

"This is fucking awesome, 【Dad】♥♥ My cock's throbbing like crazy and won't stop♥ Let's shoot our cum right into the filthy assholes of these pig parents together!!!"

"You said it, 【Koichi】! Got it!! Let's pour our straight father-son thick milk deep into the perverted, sloppy assholes of these disgusting homo bastards who claim to love cock♥♥♥"

　【Shinji Fujiwara】and【Koichi Fujiwara】twisted their cocks deep into the guts of the men who were their former son and former father, thrusting their hips back and forth like beasts. Each time, flesh collided, filling the room with the lewd sound of slapping flesh. If 【Shinji Fujiwara】's wife came home and saw this scene, it would be game over. This thrilling situation caused pleasure chemicals to gush out in their new minds, driving them closer to ejaculation.

"I'm cumming, 【Dad】♥♥ My first creampie in this body…… My head's…… going crazy!!!"

"Me too, 【Koichi】♥ Let's go crazy together with me♥♥ 【Mitsuru】, I'm sorry…… I'm gonna fill your loose asshole up with my cum, ooooh♥♥♥"

　They declared loudly, climaxing almost simultaneously. Hot liquid flowed into 【Mitsuru Isobe】's intestines. Deep inside 【Morihiko Isobe】's body too, an extremely thick cock thrust in, spewing out sticky fluid with a slurping sound. Drunk on the lingering pleasure of thoroughly violating the man who once was his son, the man who once was his father, the two pulled their cocks out with a slurping sound. Despite having just ejaculated, those cocks still retained their heat and hardness.

"Gehehe…… This is amazing, 【Koichi】! I'm gonna get hooked on this stuff, I can tell♥ I'm so turned on, my untouched virgin asshole is throbbing like crazy♥♥ 【Morihiko】, take my virginity with your pathetic, little uncircumcised cock♥♥♥"

"Hmph……! I can't…… hold back anymore either♥ Fill my asshole with 【Mitsuru】's stinky cock full of smegma♥♥"

　【Shinji Fujiwara】 and 【Koichi Fujiwara】 forcefully pinned down the man who once resembled themselves. They slowly brought their erect cocks closer to the tightened hole. Then, they thrust them in all the way to the hilt.

"Yeahhhhh♥♥♥ This is it, this is what I wanted♥♥ Getting my asshole dug out by a filthy male cock feels way better than shoving my cock into my wife's pussy♥ The feeling of falling into being a perverted homo bastard, submitting to a cock in my straight body, is fucking amazing♥♥"

"Oh, ohhh……!! Damn!…… I love getting my asshole dug up too♥ I'll live as a homo for life♥♥ Arghhh♥♥ Oohhh!! 【Mitsuru】! More…… more of your stinky cock full of smegma, fuck my ass with it♥♥♥"

""Stop, stop it, please♥♥♥""

　The deep, throaty groans of the men never ceased. If anything, they only grew more intense. The two pinned beneath them could do nothing but hang their tongues out, their faces contorted in ecstasy as they drowned in pleasure. Perhaps aroused by such a sight, 【Shinji】 and 【Koichi】 slammed their hips even harder. The sound of bodies colliding echoed throughout the room, filling it with an overwhelming scent of sweat and semen. 【Mitsuru】 and 【Morihiko】 released copious amounts of white fluid, filling their partners' holes. Whether from the sheer excitement of sexual intercourse between those who had swapped bodies, or perhaps due to their physical compatibility, the four reached climax again and again at an abnormal pace.

"Haa…… haa…… mmmph... This is perfect……♥♥ The fireman's thick cock hose just won't stop shooting……♥♥ Once we get used to this, regular sex might not satisfy us anymore…… huh, 【Koichi】?"

　【Shinji】 muttered, panting heavily. Next to him, 【Koichi】 had been lost in ecstasy, basking in the afterglow, but when his father spoke, he snapped back to reality and lifted his face.

"Yeah, 【Dad】♥ I never knew something this good existed in the world—I've been missing out all this time……! You've turned into one hell of a sexy body, 【Dad】, and just looking at your face and body makes my new cock rock hard♥ Let's fuck like crazy before Mom gets home……♥"

　【Shinji Fujiwara】 and 【Koichi Fujiwara】, father and son, pressed their bodily fluid-drenched, muscular bodies together, exchanging saliva in a fierce deep kiss. Beside them, 【Mitsuru Isobe】 and 【Morihiko Isobe】, father and son, also passionately wanted each other's bodies.

(End)
