Homecoming

"Oof, there we go."

　Shiro Aida sank his sturdy body into the sofa and pulled the tab on a can of beer while still wearing his sweat-stained work clothes. As the carbonation fizzed, the fatigue of the day washed down his throat. Outside the window, it was already dusk, and the cicadas that had been so loud during the day had grown distant.

　He felt like he had become sluggish, both physically and mentally, after turning forty. The fatigue from his on-site work lingered even after a night's rest, and the silence of an empty home sometimes weighed heavily on him.

　It had been ten years since his wife's death. Two years ago, he had kicked his son Yukio out of the house──, immediately after Yukio graduated from high school.

'Dad, I like men……'

　Yukio had confessed with a tearful expression, but Shiro had shouted back at him.

'Don't joke around! It's disgusting!!'

　Shiro felt anger and confusion, but above all, a sense of rejection at not being able to understand Yukio's words. He often recalls that day. He has no regrets. For Shiro, a heterosexual man, the idea of a man loving another man goes against the natural order of things. The feeling that his son, whom he had raised with such care, had suddenly become some kind of unknown alien left Shiro feeling utterly lost.

'I knew you'd say that, Dad.'

　Yukio smiled sadly and left the house. The home Shiro had designed from scratch and built with his friends for his beloved wife and son──.

　Since then, Shiro has lived alone in that house. He had built a slightly larger house so that Yukio could live there with him after growing up and getting married, but in the end, no one was left to live with him.

　Shiro swallowed the sigh that was about to escape him with alcohol. 'My decision wasn't wrong. So is Yukio to blame? No, that's not right either. Yukio's life is his own, and he has the right to choose the person he loves.'

　'So what if your son is gay? He just happened to fall in love with someone of the same sex. To cut off family ties and kick him out of the house just for that is pure parental ego!!'

　If it were someone else's problem, he might have said that. Shiro wasn't that narrow-minded. When he saw TV specials about gay or lesbian people, he'd just think, 'Oh, there are people like that too,' and leave it at that. But when it came to his own son being gay, it was a different story.

　Shiro couldn't get the memory of Yukio leaving home out of his head. It wasn't that he had grown to dislike Yukio. Shiro simply couldn't understand Yukio's thinking, and that frightened him.

'Dad……'

　Yukio muttered as he put on his shoes at the front door.

Shiro heard his voice over his shoulder.

'……Thank you for raising me all this time.'

＊＊＊

"Ugh!!"

　Shiro woke up to the loud ringtone of his smartphone. He couldn't sleep after that, so he ended up drinking a lot, and now there are several beer cans scattered around him. He doesn't usually feel nauseous even when he drinks too much, but his head is throbbing.

　Fortunately, today was Saturday, a day off, but there was always the possibility of a call from a client company. Holding his aching head, Shiro looked at his smartphone screen and instinctively covered his mouth with his hand.

　The name displayed on the screen was Yukio.

"……!"

　After a moment's hesitation, Shiro tapped the call icon. He held the smartphone with trembling fingers as he spoke. His voice sounded a little husky.

"Hello……"

"……Dad, it's been a while. Sorry for calling so early in the morning……"

　The voice on the other end of the line was undoubtedly his son Yukio's, but it seemed much lower than the last time they had spoken. It was so nostalgic that Shiro felt like crying. 'Are you okay? How have you been? Come home right now,' he wanted to say. But he was afraid that if he opened his mouth, he would say the opposite of what he meant, so Shiro just remained silent.

'This is sudden, but…… I've decided to get married. …… My partner is a woman. She has a proper job and is a kind person.'

　The words didn't quite register in Shiro's mind. Still, Shiro felt a warm glow in the depths of his heart.

"……I see…… I see……! I'm glad you've changed your mind, Yukio!"

　Shiro felt a sharp sting deep in his nose. He smiled to hide the tremor in his voice.

"I'll forget everything…… The truth is, I've always cared about you……"

　Shiro felt a deep sense of relief at the fact that his son was not gay.

'Thank you…… Dad. Then I'll come back tonight with her.'

　Even after the call ended, Shiro continued to stare at his smartphone for a while.

(We can start over…… as father and son.)

　He gently placed his hands together in front of his wife's portrait, which was displayed in the corner of the room.

(Listen to me, you. Yukio is coming back. He's grown up…… into a 【normal】 man.)

＊

　After finishing his long-awaited conversation with his son, Shiro forgot about his headache and busied himself with cleaning the room and shopping for groceries. The thought of Yukio coming home made him feel as if he had regained the vitality he had lost years ago, and Shiro busily went about his household chores with a vigor he hadn't felt in a long time. Thanks to his experience as a single father for several years, he had gained some confidence in his cooking skills. He imagined several of Yukio's favorite dishes and arranged them on the table.

　The doorbell rang just after seven o'clock in the evening. When he opened the door, there was a familiar face.

　Yukio's skin was tanned from the sun. His hair was shorter than before, giving him a more masculine appearance. What caught Shiro's eye most was the broad shoulders and thick chest visible beneath his T-shirt.

"……Yukio?"

　The moment Shiro saw Yukio, he knew it was his son, but those were the only words he could utter.

"Yeah…… I'm home, Dad."

　Yukio smiled as he said this, looking more robust than before. Shiro couldn't help but hug his son tightly. Even though it was a hug between two men, for some reason, his heart felt warm.

"I'm glad you're back…… my dumb son……"

　He muttered this in a low, trembling voice, and Yukio responded by patting Shiro's back just as strongly.

"I'm glad to see you looking so well, Dad."

　The two entered the house and sat down at the table. They sipped miso soup as an awkward but peaceful time passed.

　"What about your girlfriend?" Shiro asked. Yukio smiled slightly and replied.

"She has work to do. I think she'll be able to come tomorrow."

"I see…… Well, take your time. It's been a while since you've been home."

　Shiro's nerves relaxed a little. Yukio, sitting across from him, looked around the room.

"Buddhist altar hasn't changed, has it?"

"Every morning, I light incense for your mother. One for you too, of course."

　Yukio sat in front of the Buddhist altar and put his hands together. He was probably telling his mother about the marriage. Thinking about that, Shiro felt a sense of reality again. His son had returned as a 【normal】 man, not a homosexual. Shiro raised his cup.

"Yukio, you can drink now, can't you? Come here and have a drink. Tonight is a celebration."

　At that moment, Shiro still didn't know. He didn't know that his son's return wasn't just a 【reunion】. And he didn't know that everything would change that night──.

＊

　The two men were drinking heavily. Shiro's accumulated fatigue from his daily life was dispelled by the excitement of drinking with his son for the first time. Shiro's body was enveloped in a pleasant sense of exhaustion. Although he and Yukio only talked about trivial matters, strangely enough, the conversation never faltered. There was no awkward atmosphere, and it felt as if they had returned to the way things were before 【that day】.

　Shiro drank the beer placed on the low table and smiled at his son Yukio, who was pouring it for him from across the table.

"Hey, Yukio. It's really nice to drink together like this. ……Thanks for coming back."

"Yeah…… I'm happy to be able to drink with you like this too."

　Yukio smiled softly. His face retained traces of his former self, yet his mature features gave him an oddly calm appearance. Shiro rubbed his flushed cheeks with his palm and gazed intently at his son before him.

　After finishing an unknown number of beers, Yukio spoke up.

"Dad……"

　Shiro looked up at the sudden call and saw Yukio standing right next to him. They were so close that their shoulders almost touched.

"Hey……, when did you get so close to me…?"

　Before Shiro could finish speaking, Yukio leaned over him, putting his weight on him. Shiro, who had let his guard down, was instantly pinned down.

"Dad, I'm sorry. The truth is…… I'm not getting married."

"……Huh?"

"Because I'm gay."

　Shiro's hand stopped. He thought his ears were playing tricks on him. He couldn't understand what those words meant at first.

"……Gay? What does gay mean? You mean…… homosexual? But you said you were going to get married……"

"It's a lie. A lie to see you again."

"…………"

　Shiro furrowed his brow. He understood the meaning of the words. But he couldn't accept it as reality.

"You're teasing me, aren't you?"

　Shiro smiled wryly.

"You're resentful of my attitude that day, so you're lying to make me feel bad, right? In this day and age, a man who can't accept homosexuality is pathetic. I regret it. I was a failure as a father. So, please tell me the truth, Yukio!"

"No, Dad. I'm really gay. I've always liked men like you…… strong, rugged, and uncompromising."

"……Stop it."

"Men like you, who don't even try to understand people like us, who are the embodiment of a male-dominated society... I love men like you irresistibly adorable……♥"

　Every time Yukio's words piled up, Shiro could hear something inside him crumbling.

(That can't be true. My son can't be gay…… I'm sorry, Yukio. Please forgive me.)

"Yukio……"

"Dad…… Will you accept me for who I really am? Or…… will you kick me out again?"

　The voice sent a chill down Shiro's spine. Just as Shiro looked away in confusion──, their lips met.

　Shiro's body trembled. Part of it was due to the alcohol clouding his mind, but more than that, he couldn't believe what was happening.

"What the hell are you doing……?"

"Hey, Dad. I've already decided. I'm going to be you."

　Yukio's smile had a hint of madness about it. It was completely different from the gentle smile he had been wearing just moments ago. The next instant, something strange happened to Yukio's body. The muscles in his neck bulged, and his arms and chest swelled up as if he were inhaling air.

　His skeletal structure changed, and even the texture of his skin began to resemble Shiro's. His face was also gradually transforming into Shiro's likeness.

"Hey, wait! What's happening……!"

　Before the stunned Shiro, his son was undergoing a transformation into someone who looked exactly like him──.

＊

　Yukio's face gradually changed to look just like Shiro. His jet-black hair seemed to be sucked into his scalp as if it had been cut short, and its texture became stiff and coarse. His eyebrows were unkempt, thick, and clumsy, his eyelids were swollen and droopy, and his original double eyelids had somehow changed to single eyelids. His nose became thick and rugged in texture. His lips also grew unusually thick, and a masculine aura began to seep into his expression. The sharp contours of his face were pushed inward, becoming square and rugged.

"Haah……, it felt so good♥"

　The moment that voice hit Shiro's eardrums, his thoughts froze for an instant. It was his own voice. The sweet, cloying sound, mixed with the smell of alcohol, was unbearably unpleasant…… yet, something about it felt off.

"Haha…… This must be a dream, right? I drank too much and passed out……"

　Shiro muttered to himself, as if to convince himself, and held his head in his hands.

"It's not a dream, Dad."

　【Shiro Aida】 smiled slyly.

"I used a special drug to copy your body. It's not just the appearance. The sweat dripping from your skin, your voice hoarse from drinking, the way your hair grows, even your DNA── everything is the same. Even a doctor couldn't tell the difference."

　Yukio stroked his chest with satisfaction, then slid his fingers down to his lower abdomen. The boxer shorts, which had become too tight due to his enlarged body, were clearly bulging uncomfortably. A black stain was dampening the peak of the fabric.

"What the hell are you doing……?"

"It’s not only me, Dad either♥"

　At Yukio's words, Shiro suddenly looked down at his crotch.

　……Shiro had an erection.

　His mind went blank. He couldn't believe it. Why, in such an abnormal situation?

"The two of us, who have become identical due to this drug, can share sensations. If I kiss you, a mysterious power will let you feel all that I am. Physical changes, and even thoughts."

　Yukio's face twisted in pleasure. It was an expression of lewdness that Shiro himself had never seen before.

"Yukio, you're out of your mind……!"

　Contrary to his words, something was stirring inside Shiro.

──It should be disgusting.

──It should make him feel nauseous.

──For some reason, he couldn't take his eyes off the man who looked exactly like 【himself】.

　Shiro had always taken pride in his body. His well-toned muscles, tanned skin, and the rugged charm of a man who had lived through the years. Yet he had never once felt desire for himself.

　And yet now, he couldn't help but see the other 【himself】 standing before him──Yukio, as something undeniably lustful.

＊

　Shiro's heart was racing.

　It was stronger and more intense than when he had fallen in love with his senior female manager in the judo club in middle school, or when he had spent his first night with his wife. And Yukio, who looked exactly like Shiro, was also breathing heavily, just like Shiro.

　He took off his shirt. He took off his underwear.

　Like a mirror image, Yukio stripped off his clothes in exactly the same way as Shiro. Muscular arms, defined abs, and…… even the penis hanging between his legs, everything was the same shape and size. The curve, the protruding veins, and the transparent liquid dripping from it.

"……You really have become just like me, haven't you?"

　Shiro muttered in a daze, and once again, Yukio's emotions flooded into his mind like a river bursting its banks. How much Yukio had adored Shiro. How much Yukio had admired, loved, and longed for Shiro.

"Dad……"

　Naked Yukio embraced Shiro's body. His skin was hot and damp, drenched in sweat. And the thick male pheromones rising from his groin pierced Shiro's nostrils.

"Ah…… it's Dad's scent♥"

　Yukio closed his eyes in bliss and buried his face in Shiro's chest. Yukio stuck out his tongue and licked Shiro's nipple. Shiro let out a pathetic 'Oh!' But Yukio didn't care and sucked on the other nipple too.

──Was I liked myself?

　Such a delusion fleetingly crossed Shiro's mind. It had been ten years since his wife passed away. He hadn't been with anyone since. It wasn't that he lacked sexual desire. In fact, he thought his desire was stronger than most. But he had never felt romantic feelings for any woman other than his wife. Every time his testicles felt full, he would carelessly stroke his penis and ejaculate into a tissue.

"I've always wanted to lick it…… dad's sweat……"

　Yukio was engrossed, running his tongue across Shiro's chest. Yukio's face was slack, his nose stretched out. 'Had I looked this pathetic when I was having sex with my wife?' Somehow, Shiro's anger and confusion toward Yukio had vanished.

(Was I waiting for this day to come……?)

　At that moment, Shiro had only one impulse.

　He wanted to love 【himself】. Shiro lifted Yukio's chin and locked eyes with him.

　A rugged, square jawline. Thick eyebrows and swollen, single-lidded eyes. The smell of sweat seeping from a muscular, well-built body. The fact that they were all the same only served to heighten Shiro’s excitement.

　They reached out to each other, their palms touching. Then their lips touched. The man's lips were dry and slightly chapped. But their warmth certainly filled Shiro's heart.

　In the thick silence, the two 【Shiro】 exchanged a second kiss.

　It was not between father and son. It was not even between two men. It was love for himself.

＊

　Shiro and Yukio pressed their lips together greedily. Like beasts, they entwined their saliva-covered tongues and pressed their thick, muscular chests together. Beneath them, their pre-cum-covered cocks shook violently as they pressed their glans against each other like a kendo tussle. Their cocks rubbed together slickly. With each stroke, they grew harder, their veins bulging.

"Dad……"

"I can't take it anymore……"

　Yukio pulled away from his lips and murmured dreamily, and Shiro passionately pressed his lips against Yukio's once more. He was like a starving dog. The burning desire rising from the depths of his body was unstoppable. Shiro wanted more—these thick lips, this saliva-covered tongue, this sweat-soaked skin—he wanted it all to be his!

　"Mmm♥" Yukio let out a sweet breath through his nose. Encouraged by his reaction, Shiro pushed his tongue deeper. Their bodies pressed tightly together, as if they had become one. The more they kissed, the more their emotions intertwined and melted together. For Shiro, the rationality of being father and son no longer existed.

""I'm cumming♥♥♥""

　The two reached climax simultaneously. A hot, sticky sensation spread across their abdomens. The semen was the same thickness, the same volume, and the same temperature. And with the same sensation, their penises trembled and shook as they squeezed out the remaining semen from the tips of their glans. The pulsation, size, and hardness were all exactly the same.

"Your semen is hot……♥"

　A low, muffled voice echoed deep within Shiro's ears. It was the same voice as his own. But hearing it come from another person's mouth sent a shiver through Shiro's core. Thick arms wrapped around his back, and each stroke sent a wave of heat across his skin. Their chests pressed together, their heartbeats blending into one. It was as if their very hearts were in sync.

　Their hips collided. Their heavy bodies rubbed against each other violently, and the moist heat spread slowly across the futon. There were no words. Only their warmth, their breath, and their gazes conveyed everything. 'I am being loved by someone who was just like myself right now──'

　That perversion was unbearable.

　The intertwined bodies creak slowly. Rough hands stroke the shoulders, crawl across the chest, and trace the abdomen. In sync with those movements, Shiro's consciousness slowly sinks into a deep swamp.

＊＊＊

"Hey, welcome back, Yukio. Dinner's ready."

　Shiro greeted the massive man who entered through the front door with a voice of encouragement. The man's work clothes were covered in mud, and his tanned skin glistened with sweat. The man, who carried a helmet covered in scratches, was undoubtedly 【Shiro Aida】 himself.

　In fact, he was Yukio, a perfect copy of Shiro's body. He was another 【Shiro】 who had spent the day working as a construction worker at the site.

"……Ugh, I’m exhausted, Dad."

　Yukio said bluntly, but he smiled proudly. His sweaty muscles under his work clothes glistened beautifully in the light of the electric lamp.

"But you know, every time your colleagues call me 'Shiro-san, Shiro-san'…… it’s weird, but it gives me excitement."

　Yukio scratched his nose awkwardly, but couldn't hide his joy.

"I've become 【Shiro Aida】…… I really feel it now."

　Shiro smiled quietly.

"I see…… That's good."

　There was already a bond between them that went beyond that of parent and child. It was a resonance that should not have been possible. But to them, it seemed only natural.

　Yukio approached Shiro.

　Still covered in sweat and the scent of dirt, Yukio leaned in close to Shiro and gently pressed his lips against his.

　In that instant, all the memories of what Yukio had experienced that day flooded into Shiro's mind like a torrent. Conversations with the construction workers, the scorching sun, the smell of steel beams. And the excitement that filled Yukio's chest every time he was called 【Shiro】.

　No matter how many times he experienced it, Shiro still couldn't get used to the feeling. The cock that had been limp just a moment ago gradually began to erect. His underwear was soon soaked with pre-cum. Their lips parted, and they gazed into each other's eyes.

"How was it? Did you feel it, 【my】 experience?"

"……Yeah, it was amazing."

"Hehe, good. Then──, let’s have fun tonight too♥"

　Yukio raised the corners of his mouth mischievously, and Shiro laughed back. The two who had once been father and son were now completely different.

"Is it my turn to get fucked today? But you know……, I’ve never had a cock shoved up my ass before, so I don’t think I can do it."

"It's okay, Dad. I told you. If we kiss, we'll be able to share each other's physical sensations……, mmmmm♥♥"

　In Yukio's right hand was a dildo as thick as an eggplant. Such a thick object was being pushed into the tiny asshole of 【Shiro Aida】. With a sound, it expanded, scraping against the intestinal walls and crushing the prostate.

"Ugh, haa……♥ See? It's okay, right? Look at 【me】……♥"

　With the thick foreign object still thrust into his ass, Yukio pressed his lips against Shiro's.

"Nmmmm……!!"

　The intense pleasure causes Shiro's vision to flicker. Yukio's saliva is poured into the back of Shiro's throat, enveloping his entire body in a sweet ache. Shiro's anus is stretched open by an unknown force, his muscles relaxing. His anus, which he had only ever used for defecation, is being developed like a female genitalia.

　At the same time, Yukio's emotions and sensations flow into Shiro's mind. The stimulation of pain and pleasure explodes in his brain, and a thick, sticky fluid oozes from the tip of his penis.

"Ugh……♥ No……! My ass is going to split open!!"

"Hey, 【me】~, pull yourself together! ……Look, your asshole is so stretched out that my cock can slide right in…… mmm♥ It's sucking my cock in so nicely……"

"Wait, wai…… Ugh!"

　Yukio mercilessly thrust his hardened cock into Shiro's relaxed anus. With a sound, the foreign object invaded Shiro's body. Painful—suffocating—disgusting. Yet, through the sensory connection with Yukio, the only sensation Shiro felt was pleasure. His anus contracted, clamping down on 【Shiro Aida】's cock.

"Ah……, my cock is inside 【my】 ass♥♥"

"Oh my gosh!! It's going inside me!! 【My】 cock! It's so hot!!"

　Yukio began to move his hips back and forth. The sound of water began to echo from the point of contact, and Shiro let out a scream. However, his cock did not soften but became even harder, and pre-cum was overflowing from the tip. Every time 【Shiro Aida】's penis thrust in and out, Shiro's intestines eagerly welcomed it. The inner walls contracted, sucking on Yukio's cock like a tongue.

"Oh…… it's amazing……, inside 【me】…… it's so hot and writhing……♥"

　Yukio's tone grew increasingly lewd. His hips moved deeper and deeper, relentlessly attacking the spots that made Shiro feel good. The large glans rubbed against the prostate through the intestinal wall, and Yukio's cock stimulated Shiro's mucous membrane. Each time, Shiro lifted his hips and let out a moan.

"Ah♥ Ohh♥ Ahhh♥"

　It was no longer clear which of them was making the sounds. Shiro, who had never experienced sex between men before, was being taught the pleasure of being taken for the first time by 【himself】. The scent of sweat and pheromones emanating from Yukio's body, his hot breath, his thick neck, his muscular arms…… everything continued to stimulate Shiro's senses.

"I'm cumming…… I'm gonna cum, 【me】!!!"

　With the final thrust, 【Shiro Aida】's massive cock ejaculated, and a large amount of semen was poured deep into Shiro's body.

"OHHHH♥♥"

　The sensation of 【his own】 genes being pumped into Shiro's asshole from the wildly throbbing cock filled his intestines, and he too reached climax. The emptiness that had filled his heart for so long was now being filled with thick, sticky mucus.

　Shiro's beloved son was gay, and he was a perverted bastard who loved his father. 'But none of that mattered anymore. All I had to do was surrender to this pleasure…… That's what I thought. Because I too wanted to become one with this man, with 【me】──!'

"More……, more intensely, 【me】♥♥"

　Shiro remained connected to Yukio as he began to move his hips vigorously once more. Sloppy, lewd sounds echoed from his buttocks, and the fluid overflowing from their union soaked the sheets. At first, Shiro's anus felt so painful it seemed like it might tear, but it gradually softened and relaxed, and now it had completely transformed into a dedicated penis case for Yukio── no, for 【Shiro Aida】.

"Ahh♥ 【Me】, this feels so good! Your asshole, your cock, your big body…… everything is amazing! I can’t live without 【me】 anymore……! Let’s be together more, more, more♥♥"

　Yukio's wet tongue extended and intertwined with Shiro's. The more they exchanged saliva, the more their body temperatures blended and melted together, creating a sense of unity.

　The two of them pressed their thick chests together. The sound of their hearts beating so loudly it felt like they might burst was transmitted directly through their skin, causing Shiro's entire body to tremble. In the next instant, his anus clenched tightly and spasmed, and thick semen gushed out from the tip of his penis. At the same time, a large amount of white fluid flowed out from Yukio's cock, staining Shiro's insides white.

　'My son's appearance has changed. At the same time, perhaps the form of parental love had also been distorted. But it was okay. Because I could continue to live in this house, built for the family I loved──.'

"I love you, 【me】. From now on, we will always be together. Always, forever……"
