My first love turned to skin (Pixiv Fanbox)

　Seita Sugaya, of average height and weight. He is an ordinary looking eighth grader who recently realized that he is a homosexual.

　The reason for this realization was his uncle.

　His house is what is called a two-family house, with his grandparents, parents, and his sister living under one roof. Because of that, at New Year's, all the relatives would come to his house. Thanks to them, he had a lot of fun with his relatives. Among them, his uncle was especially fond of him, and he also loved his uncle.

　His uncle's name is Daisuke Sugaya. He is an ordinary businessman by profession, but he is still an active rugby player and is very stout. At first glance, his bearded face gives him a stern and scary look, but when he smiles, he is quite cute. When he goes to work, he is said to be wearing a suit and tie, but when he is working with Seita, he is usually wearing a tanktop and shorts.

　Seita loved Daisuke's well-trained body. His chest was so big that his tanktop would rip off his chest, and his shoulders were as big as melons. His arms were as thick as logs and his legs were hairy. He had a huge butt and a bulge between his legs that made me wonder if he was stuffed. When Seita was a little boy, he never doubted that the feelings he had when he saw Daisuke were those of longing.

　But it was not to be…… When Daisuke was drinking and snoring, Seita saw a cock spilling out of his shorts and realized that he was a gay man who was sexually aroused by a man.

　Hurrying back to his room, he buried his face in his pillow and tried desperately to forget what he had just seen. But the scene kept replaying over and over in his mind. The lingering odor of Daisuke sticks to the back of Seita's nose, tormenting him. He felt sick of himself like that.

　In the end, New Year's Day ended with him in agony, not knowing how to come to terms with these feelings. In front of his father and mother as well as Daisuke himself, Seita still acted as a normal nephew who liked his uncle. He played video games against Daisuke and played catch with him…… Despite the difficulties, Seita is proud of the fact that he was able to treat Daisuke in a normal way. Seita would continue to see Daisuke a few times a year, and he would be able to keep it that way. Or so he thought.

　However, due to a sudden job transfer, Daisuke has been transferred from a branch office outside of the prefecture to the head office near his parents' house. He is single and has decided to live with his parents in order to save money on rent. This meant that Seita could no longer avoid seeing Daisuke every day. Every day, his uncle comes into his sight.

　He had never seen his uncle before, a cool uncle in a suit. On the other hand, his uncle was as disheveled as ever. His uncle who seduces him naked on top of his body…… All of those were sexually arousing for him. But he had to keep those thoughts to himself if he didn't want anyone to find out that he was gay. He had to go on with his life as before, even though it drove him crazy.

＊＊＊

　Two years had passed since Daisuke came to live at Seita's house. He was now a freshman in high school. During the two years, Seita had grown taller than his father, who was of average height, and to the point where he was on par with Daisuke, who was a big guy. His face also became more mature, and a girl in his class even confessed her feelings for him. If he were not gay, he would have been elated. But for him now, he is just confronted with a reality he doesn't want to see……

“Phew……”

“What's the matter, Seita, you sighing?”

　Even though it was still early evening, Daisuke, who was lying on the sofa in the dining room watching TV with a beer in his hand, called out to Seita.

“It's nothing.”

“Really? If you have any problems, you should talk to me about it, okay?”

　He then put his hand on Seita's head.

(Stop it, Daisuke, if you do that, I'll…… be……!)

“Daisuke!”

　Seita grabbed Daisuke's arm and pushed him straight down on the sofa. He brought his mouth close to his ear and whispered softly.

“What I'm worried about is──【love】.”

　As soon as Daisuke heard those words, his face clouded over.

“Seita, you're a gay after all……?”

　Daisuke sat up and looked down at Seita with disdainful eyes. Those benevolent eyes that had been directed at him since he was a child were nowhere to be found.

“No! I'm not a gay……”

“Shut up! You're…… making me sick!”

　Daisuke pushed Seita's shoulders away and stood straight up to glare at him.

“I've lived my whole life believing that there are no homosexuals in my family or relatives. But I never thought that you, whom I have been loving so much, were a perverted bastard……”

　Daisuke changed his tune, and he then proceeded to roll up on Seita. That in all the years he has lived as a rugby player, he has been wooed by men many times, forced to suck cock and get his ass dig by male seniors. That he has thought over and over again that he is sick of it, but that he has still suffered because he has been unable to talk to anyone about it.

“Damn, that sucks! I feel nauseous……! Seita, you are sick! I'll tell Kensuke (Daisuke's brother) and Ayaka (Daisuke's sister-in-law) and take you to the hospital!!”

“……”

　Seita stared at Daisuke's face. Tear after tear poured out, one after the other, and they would not stop. This is a lie. He can't believe it. There was no way that gentle Daisuke would be thinking like this. This must be some kind of mistake──.

　But Daisuke, whose ears and neck were so red that they were a dark color, grabbed Seita's arm with such force that it crushed his own. The pain seemed to tell him that what Daisuke was saying was true.

(It hurts, it hurts, Daisuke……!)

　Scared, Seita unconsciously put his hand on the necklace he was wearing. He forgot when it was, but it was the sword-shaped necklace that had been placed under his pillow on Christmas Day. When he thrust it into Daisuke's back, the blade entered his flesh and he leaned against Seita.

＊

“Agahhh……”

　Daisuke slowly collapsed into Seita's body, breathing roughly and repeatedly. With each breath he became flimsy skin.

──Daisuke has become skin.

　Without time to think about where his muscles had gone, Daisuke's body was turning into flimsy skin. The skin that was once Daisuke's was squishy and looked like a wetsuit in Seita's hands. Horrified, Seita clutched the skin to his chest, ran to his room, and shoved it into his wardrobe.

“Ugh…… ugh, Daisuke……”

　He crawled straight into bed. Even though he could feel the warmth of the futon on his skin, he couldn't stop crying as he thought back to Daisuke. Tears of anger and sadness for his uncle, including the surprise that his body had turned to skin, why he had never accepted his feelings, and why he had said such horrible things to him, flooded his eyes. Seita continued to cry until he was so tired that he lost consciousness.

(What should I do……?)

　When he woke up the next morning and sat down at the table in the living room, his mother offered him breakfast with a smile. His father also looked the same as usual, munching on a loaf of freshly baked bread. It was like a dream that Daisuke had been turned into a skin by his hands yesterday.

“What's the matter, Seita? You don't look so good. You didn't even come to dinner when I called you for dinner last night……”

“It's nothing, Mom.”

　Seita smiled, trying not to let anyone realize what had happened last night.

　His father and mother did not seem particularly concerned that Daisuke had not come home for the night. Unlike a child like Seita, Daisuke, a middle-aged man, would not been surprised if he did not come home for a day without a call.

　After finishing breakfast, Seita went back to his room and took his uncle's skin out of the wardrobe. Turning it over and looking at the back, he saw that it had what looked like a zipper. Or rather, a zipper itself. When he pulled it down with a jiggle sound, the skin was hollow.

　Such curiosity swirled inside Seita, wondering what would happen if he put this on. It must surely be better to wear it naked than with clothes on. With that thought in mind, he stripped off his T-shirt and boxer shorts, stripped naked, and plunged his arms and legs into Daisuke's skin.

　The slimy texture covered his entire body. Finally, he pressed the skin of his face against his own and his body began to creak, making strange sounds as it squirmed and squirmed. Seita became assimilated into Daisuke, savoring the sensation of being crushed by flesh, of his whole body swelling up.

“Aggaaaaaahhh!”

　The blood in his body felt like it was boiling, and his limbs stretched out in Daisuke's skin, growing thicker and tougher by two sizes in no time. The sensation of every muscle in his body rising up was incomparably pleasurable. The sensation of his body becoming one with his favorite uncle's body. The desire to release something from inside his body flooded back into him, and the cock between his legs, which had been atrophied, became so energized that it warped vigorously.

“Oh……, n-oh……♥”

　Seita's wild voice spilled out from his throat as if squeezed out. He squeezed his chest, stroked and rubbed his abs, and as he lowered his hand, he began to squeeze his uncle's erect cock.

“Ooooh! Oooooooooh♥♥♥”

　It feels so good…… Seita's body was more sensitive than he had ever felt before. The feeling was so extraordinary that it could not be compared to masturbation. Especially the sensation of cock between his legs getting hard was unbearable. As he kept squeezing it while making lewd sounds, he felt as if his strength was being drained from his whole body. The sensation that he was somewhat playing with someone else's body turned into the sensation that he was comforting his own body, filling his heart. Finally, he felt something like heat rising up from between his legs, making his whole body jerk and twitch.

“I'm cumming♥♥ Oooohhhh♥♥♥”

　Daisuke's wild moaning was followed by a torrent of white spunk shooting out of his erect cock. The pleasure of releasing the thick, smelly semen was tremendous. His breathing became ragged and his heart palpitated violently. He had never masturbated with such a great feeling. He felt his asshole tightening and he could feel Daisuke's anus pleasuring itself.

(Oh, I’m going crazy……♥)

“Hah~~♥ Phew……♥”

　After a while, when his climax was over, Seita relaxed his whole body and rolled over on the bed. He turned over, clutched the sheets with both hands, and rubbed his cock against the bed to soak up the afterglow. But soon it was post-nut clarity for him. Now that he is wearing his uncle's skin, the person 【Daisuke Sugaya】 exists. But this time, he── 【Seita Sugaya】 is not present.

　He looked at the clock and saw that the time for lunch had already passed, and the hands were pointing to 7:00 PM. He had no choice but to go to the dining room. With that in mind, he wiped his sweat and semen off with a towel, sprinkled perfume on his body, put on Daisuke's clothes, and left the room.

＊

　All the family members except for 【Seita Sugaya】 were present in the dining room. His parents, grandparents, and younger sister have been looking at him with worried expressions, but he is not sure what their true intentions are. At any rate, he put a smile on 【Daisuke Sugaya】's face and asked what was for dinner tonight.

“Phew I'm so hungry, what's for dinner tonight, Ayaka?”

“It's Seita's favorite fried chicken today, I wonder where that boy went? I knocked on his room but he didn't answer…… Hey Daisuke, do you know anything?”

“Oh, Seita! Let's see……, if it's him, well……, he said he's staying at his friend's house today, hahaha.”

“Oh, really? I'm glad to hear that. He's making me worry about him……”

　Seeing the relieved looks on the faces of the others, including his mother, who mumbled to herself that there was no answer when she called Seita's smartphone, he too patted his chest. He was somewhat concerned because even when he looked at himself in the mirror, although he looked just like 【Daisuke Sugaya】 himself in his uncle's skin, he was still a bit uneasy. But now he was in such a state that even his father, Daisuke's blood brother, and his grandparents, his parents, could not tell him apart from Daisuke. His back was shaking with an indescribable feeling of pleasure as he popped the heaping bowl of rice into his mouth.

　Seita, now in Daisuke's body, eventually ate the heaping bowl of rice and side dishes and returned to Daisuke's room. Even after all that food, he still felt like until he was 80 percent full, but he had to put that aside for now and get Daisuke back to his normal state. Entering Daisuke's room, Seita opened a drawer in his desk and was surprised. Because a dildo in the shape of a man's penis was warped like a snake and staring back at him. In the back of that, there were a variety of other adult toys. He had never known about Daisuke's taste in such things, and to be honest, he could not hide his upset.

(How did Daisuke, who seemed so prejudiced against gays, get this stuff……)

　He gulped audibly and slowly reached for the dildo. The squishy texture of the dildo is strangely erotic and naturally makes his cock harden.

【I want to fuck this inside my ass!!】

　He felt as if Daisuke's body was telling Seita that, and he couldn't stand it any longer. He took off his clothes and stripped naked, and slowly lowered his hips toward the dildo fixed on the floor, splattering pre-cum. The moment he heard the sound of the dildo entering his asshole, an indescribable feeling of pleasure ran through his whole body.

“Oh, yeahhhhh♥♥”

　He accepted the dildo into his asshole, bobbing his Adam's apple up and down and moaning. The sensation of his anus expanding as he accepted the foreign object was unbearable. His body was filled with a thick mass of flesh.

“Nggy, aaarrrrhhhhh♥♥”

　The disgusting sound of the dildo rubbing up and down his bowels echoed through the room. Seita enjoyed the lewd sound as he pulled the dildo in and out of his uncle's anus. Each time he pulled it out, it felt as if all the strength in his body was suddenly released, and his body tingled as he forcefully inserted it deeper and deeper. Each time he rested his whole body on the dildo fixed to the floor, his arousal level increased.

“Oh, my gosh~~~♥♥♥”

　With a wild moan, he was addicted to the dildo before he knew it. The floor was already soaked with cum, and the whole area was filled with the smell of male. When he pressed his asshole against the dildo, white fluid arced out from his cock and splattered. The feeling of release was irresistible, and he moved his hips up and down again and again. With repeated violent climaxes, his eyes flicker and his mind goes blank. Every time the middle-aged man's panting voice echoed in the back of his head, he felt as if he were becoming Daisuke, and his whole body was almost debauched.

“Hahhh♥♥ Daisuke……, Daisuke, 【I】 am Da……isuke!!!”

　Every time the dildo rubbed against his gut, he felt as if his mind was becoming one with Daisuke's body. His uncle and him── the boundary between them became blurred and his consciousness became muddled. Finally, the time came.

“Oh, oh, ohhhh♥♥ UGGHHHH~~~♥♥♥”

　Seita's whole body convulsed violently as he spurted out his semen with the dildo inserted deep into his asshole. Even though his legs were about to cramp, he still leaned his body forward, straining his lower body. As his anus twitched and quivered, his back suddenly became itchy and mushy. It itches and itches and it's unbearable!

(I have to take off Daisuke's skin right now……)

　Without the time to worry about damaging his skin, Seita thrust the fingers of both hands into his back and gabbed off Daisuke's skin like a chrysalis hatching into a cicada. On the floor, his uncle's back, covered in sweat, the surface of his skin shiny and glistening, comes into Seita's eyes. The thing he had been wearing just a moment ago. Despite the fact that it was the skin of his favorite uncle, he felt a little creepy somehow.

　As he caught his breath and looked at it without even trying to see it, the hole in Daisuke's skin back, reminiscent of a drooling mouth, slowly closed. And the flimsy skin fabric slowly regained its thickness. His shoulders became broad and his entire back was rising……, and with it, his body was becoming visibly full of strength.

　When the phenomenon was over, Daisuke slowly looked up. His face, which had been dreamily staring at me, gradually changed to his usual fearless expression. The light in his eyes became clearer and clearer, and Seita realized that Daisuke had completely recovered.

“Well……, Daisuke……”

“Hey, who are you? Why is a bastard who looks exactly like me right in front of me? ……Could it be you, Seita?”

“Yeah, I was wearing you as a skin for a while now……”

“What? You had made me into the skin? That's ridiculous……”

　Seita somehow managed to explain in order that he had injured Daisuke with the necklace, that the injury had turned him into a skin, that he had succumbed to temptation and put on the skin, and that he had pierced his back and taken Daisuke's skin off just a few moments ago. Daisuke, who had been very excited, gradually regained his composure as he listened to Seita's story and finally looked convinced, but then looked at Seita again with a doubtful frown.

“If you've taken off me, isn't it strange that you haven't reverted to your original form? Why are you still in my form?”

“Eh?!”

　It was only when Daisuke pointed this out to him that Seita realized that he was still in the form of his uncle. He spread his palms and stared at him carefully, twisted his body around to observe his whole body, but it seemed that Daisuke was right, Seita's body was still in the form of 【Daisuke Sugaya】. He should have been in a hurry, but the masculine smell that tickled his nostrils and the feel of his chunky skin made him swoon and he almost lost consciousness.

“I don't know why you're still in my form……, but the holiday weekend is over today, and we're in trouble if we don't get back to normal soon anyway.”

“Daisuke……, do you have any solutions?”

“I mean……, if you made me into the skin with that necklace, why don't I just stick it in you and you'll be back to your normal form?”

“Ummm……? I don't think it would be that easy. But I can't think of any other way…… Then let's try that method.”

　So they immediately put it into action. Anyway, if Seita did not return to his original form, there would continue to be two people with the appearance of 【Daisuke Sugaya】.

　Seita, in his uncle's form, stood tall and naked, closed his eyes, and put all his strength into his body. The tip of the sword-shaped necklace was thrust into Seita's back, signaling Daisuke's voice. The next moment, an intense white light sparked in his head.

“Ugh……!!”

　His crotch heated up. It's as if he's about to ejaculate while still in Daisuke's form. But cumming in front of his uncle's eyes was too embarrassing. Seita bit his lower lip and continued to endure desperately. Then, after a few seconds, he suddenly felt a sensation of power draining from all the muscles in his body.

“Oh, oh……, I feel like I could take off your skin……”

　Seita thrust the fingers of both hands into his back, just as he had just removed Daisuke's skin. When he put a strong pressure on it, it made a crunching sound as if it was shedding its skin, and the skin came off again.

“I'm back to normal! I did it, Daisuke!”

　When he said so, still naked and with a cheerful expression on his face, Daisuke looked at Seita seriously from the top of his head to his toes, as if he had a question mark on his head.

“No, you're still in my form. And the skin you took off, doesn't it look more like yours than mine?”

　Leaving the two puzzled, the skin wriggling eerily on the floor…… For all intents and purposes, the skin looked exactly like Seita's──

＊

　A skin that looked exactly like Seita's was lying right in front of me. It was making me salivate. Looking at the skin, I couldn't help but want to put it on. It was as if the skin was the thing that should cover my body.

“Hey, Seita. Can I try on this skin……? When I saw it, I felt an irresistible urge to wear it.”

　I thought that Seita, who wore my skin without my permission, would not be able to refuse if he heard me say such a thing, but I could not suppress this piqued curiosity.

“If it's your request……, OK.”

　His reply came back a little hesitantly, and I swallowed my spit once more and carefully touched Seita's skin. The texture is as realistic as it looks. It was warm to the touch, and just touching it made my heart pound. The hollow space in front of me made me uneasy, but with a shout, I slid myself into it with all my might.

“OH……♥♥♥”

　Seita's skin feels so good that I can't help but let out a pitiful sound. It feels as if my whole body is being gently wrapped around it. The cock between my legs also felt itchy, and I tried to reposition it, but before I could do so, my lower body tightened up and my consciousness was involuntarily taken in that direction. I felt as if I was covered from my toes to my buttocks all at once, and I could not stop the tingling sensation throughout my body.

“Oh, God……♥♥♥”

　I tried to hold back my voice, but it kept coming out of my mouth. The slit in my back was closed and my face was wrapped in Seita's skin in no time at all. The skin of Seita, which is smaller than my body, tightens around my whole body violently and gently. I feel as if someone else has taken control of my body, and my head starts to spin. Every cell in my body was shivering from the comforting sensation, as if I were being caressed inside and out.

　Then, my body, face, and cock change, emitting obscene and creepy sounds like writhing mucous membranes. I feel as if I am being forcibly transformed into someone else's body, and a mixture of excitement and fear assails me. It's painful, it feels good, and I feel like I'm going crazy. The fact that I am exposing myself to Seita, my nephew, while he is watching me, also adds to my excitement.

“Wow♥♥♥ Ooooh……♥♥”

　I shuddered violently in Seita's skin, emitting a voice that could neither be described as a gasp nor a groan. The stimulation of having every inch of my body licked carefully filled my head with a euphoric feeling. The pleasure that I could not get from just ejaculating penetrated into my brain, and my body was being completely transformed into Seita's one. I finally couldn't hold back and embraced Seita, who had become my body, while letting the pleasure take over.

＊

　Twenty years ago. When I became a high school student and joined the rugby club, I was marked by a senior who liked men because of my blessed physique and face, and I was forcibly raped. Every day after practice, the seniors would dig my ass.

　And as this became my daily routine, my body was no longer satisfied unless it was violated in the ass by big guys. Despite my intense aversion to male-on-male sex, I made it a daily routine to go to the crusing spot and sleep with the guys I met there. When I returned home, I spent my days getting extreme pleasure by having an extra-thick dildo fucked up my asshole. I wanted to be fucked by men who were bigger than I was, but I had grown up to be bigger than most men, so I had no choice but to indulge my fantasies while digging my own asshole with an extra-thick dildo. But now, that wish I had given up on can come true. If only I could get the man in front of me now, who has become 【Daisuke Sugaya】, to fuck me in the form of 【Seita Sugaya】──.

“Seita, I'm sorry I called you creepy earlier…… I didn't want you to end up like me. I thought that if you were still young, you would be reborn as a decent human being, get a beautiful wife like my brother, and have a happy family with a beautiful child like yours……”

　I repented as I leaned toward Seita. My chest is crushed with guilt, but my body is more honest and…… than that. Now I feel like I'm going to get out of control between that sinfulness and my perverted fantasies.

“Daisuke……”

　Seita gently hugged me back. For the first time in a long time, I feel like I am being embraced by someone larger than myself. I felt as if my entire body was enveloped by him. Being enveloped by the comfortable warmth, I felt strangely calm.

“You always thought of me, didn't you?”

“Seita……, I'm sorry……”

　Seita smiled on his stern face as I mumbled.

“Don't apologize so much. And if you love me that much── from now on, 【I】 will love you!”

“What……?”

　The next moment, I was kissed by Seita. It's not a little kiss. His kisses are so rich that they entwine tongues and taste every inch of my mouth.

“Nmm♥ Hmmm……♥♥”

　My brain is not working, and gradually I'm becoming unreasonable. While my ears were being raped by the disgusting sound of kisses, I became completely absorbed in kissing Seita. While our tongues are entwined, my nephew's hand is at the same time groping my asshole. Suddenly, my mind started to panic, but my body was still pleasuring itself.

　I felt as if both my upper and lower mouths were being fucked at the same time, and my brain was being penetrated by the violent pleasure, and for some reason I couldn't think of any way to resist the pleasure.

　Is it because I am wearing Seita's skin that even my ability to think has become juvenile? When I looked into Seita's eyes, they were full of confidence. My heart was filled with excitement at the sight of my 【Uncle】, who is bigger, stronger, and more dependable than I am.

　【I】 naturally intertwined my tongue with his and completely relaxed my body as if I was letting 【Uncle】 take care of me.

“Ahh……♥♥♥”

　When he pulled his lips away from mine, I couldn't help but let out a sigh of regret. I was completely lustful from the thick kiss, and I could no longer resist the pleasure.

　I was intoxicated by the sensation of Daisuke's tongue fucking my mouth and his fingers spreading my asshole at the same time. I had been kissed countless times in my life, but the sensation was so fresh that it was as if I was a virgin again. My body is so numb from the pleasure that I can hardly stand up, and I can't even resist as he holds me like an infant.

　I felt ashamed, but I wanted to devour the pleasure of surrendering myself to a strong man, something I hadn't felt since I was a student.

　For a moment, I thought I heard a sweet sigh escape, but it quickly turned into a gasp. Daisuke's thick fingers were groping my anus as he ran his tongue over my nipples, which had become completely sensitive and erecting from his kisses. I even felt as if my whole body had become an erogenous zone. I didn't even know what was happening to me, all my senses were so acute, and my body just felt so good. Every time my body was gently caressed, my hardened young male cock would twitch and quiver, dripping with pre-cum.

“Dai……suke……♥”

　I couldn't stand it any longer and let out a few words. Daisuke smiled at me and kissed me tenderly. It was different from the rough tongue he had used earlier, it was a melt-in-my-mouth kiss filled with love.

　【My】 favorite uncle. 【My】 first love uncle. I always wanted to have this kind of relationship with him──.

“Seita……♥”

　He whispered to me, turning his gentle eyes on me. At the same time, the fingers that had been moving in my ass was pulled out, and I felt my asshole twitch with lack of satisfaction. I wanted 【Uncle】's hot cock so bad that I couldn't stop the tingling in the back of my body.

“Daisuke, please……”

　I moistened my eyes with a flirtatious voice and opened my legs and spread my asshole. I can't help but be excited by the perverse situation of being fucked by my nephew who has become 【my】 body. On the one hand, I feel like I'm going to lose my mind with shame, but on the other hand, I still want the strong male cock in front of me. I can't wait to be plunged into such intense pleasure that my mind goes blank.

“Daisuke……♥”

　When I asked again in a coaxing voice, Daisuke gulped audibly, then raised his voice.

“Seita──, I love you!”

　That one word alone sent a rush of pleasure through my body like an electric current. With a soft smile on his face, he slowly sank his hips down and placed the tip of his hot cock against my asshole, and just like that──,

”Ohhhhhhhhhhhh♥♥♥”

　With a single breath, a hard cock was thrust into my asshole. I couldn't help but let out a sweet moan of pleasure as my uncle's big body completely enveloped my entire body.

(It……, it feels too good……♥♥♥)

　The pleasure of having my whole body covered with a huge body and having my insides penetrated by a magnificent stake of flesh was tremendous. I am sure I have been fucked in the ass by many male cocks, but the memory of it is somewhat hazy, and I even feel as if I am being penetrated by a male for the very first time right now.

“Hah♥ Hah……♥♥”

　I breathe hard and let out a rough exhale. My body is hot, as if all the blood in my body is boiling. I can feel the pre-cum dripping from my cock, and my asshole is twitching, wanting to be fucked even more. I managed to cling to my uncle's chest to hold back the pleasure, but even so, my body just kept getting more and more aroused without limit.

　This must be because this is the body of 【Seita Sugaya】. Seita loves his uncle, 【me】── 【Daisuke Sugaya】 so much. That feeling is directly conveyed to me now.

(Daisuke♥ Daisuke……♥♥)

　A strange sensation as if 【Seita】's skin and 【my】 soul are becoming one. I am so happy that my uncle is raping my whole body that I am about to burst into tears.

　Daisuke's cock is inserted deep into my belly. Just the fact that my asshole is being fucked by his hot, hard cock is enough to make me ejaculate. The overwhelming presence and heat of the male filling my belly fills my heart with the pleasure of being made a female and the feeling of beimg dominated.

“It feels so good, Seita……♥”

　Daisuke began to move his hips violently as he covered me in his arms. Every time he thrusts up from below, pleasure wells up in the pit of my stomach. It was an intense sensation that could not be described as pain, but it was not unpleasant at all. On the contrary, it was the opposite. Every time the overwhelming mass of the meat stake was screwed into my asshole, my body would twitch and convulse with the first time it felt so good.

(Incredible……♥♥ His cock is the best♥♥♥)

　The pleasure of being fucked so hard by my uncle's powerful pistons that my asshole is turned up. At first, I felt nothing but pressure and a foreign object, but before I knew it, it had turned into a complete pleasure. The sensation of having my asshole pushed open with a lewd sound sent tingles down my spine. Just the thought of a thick cock going in and out of a place fingers could never reach made my mind go blank like an idiot.

“Nmm……♥♥♥”

　Daisuke started kissing me as he wiggled his hips, and then he started sucking my mouth hungrily. Of course, all the while, his lower body was moving furiously. I feel like I'm going to lose consciousness from the pleasure of being violated by the rubbing of the mucous membranes against each other in both the upper and lower mouths. He kept gouging my intestinal walls with his cock which had become so hard, that I couldn't resist ejaculating when his glans pressed against me, just as if he was going to crush my prostate.

“Ohh♥ Aaahhhh♥♥”

　Jerking and twitching, I spewed my stinky cum all over Daisuke's big body. Every time I ejaculated, my asshole would tighten up and suck on his cock, and the pressure alone was enough to make me cum again.

　My whole body was convulsing and I felt like I was going crazy. Or maybe I was already going crazy. The uncle who loves me is 【my】 nephew, and I am his 【uncle】──. My head is getting flustered and I don't know what's going on anymore.

“I'm cumming♥ I'm gonna cum, Seita!! I love you♥♥♥”

　Daisuke shouted, and at the same time, I felt something hot explode in the deepest part of my belly. I was so engrossed in his kiss that the sensation of thick viscous cum filling my bowels gave me goosebumps. Each time his cum-spewing cock pulsed, my asshole expanded to match shape of his cock. The sensation of my body changing to match the one I love. I was irrepressibly happy and joyful──.

“Oh……♥ Oh, God♥♥”

　I came again. He kissed me and poured his cum into my intestines, and I climaxed heavily. My whole body was trembling and my body was completely surrendered to Daisuke. His cock, still hard even after ejaculating, fills my belly with semen. I spewed the contents of my balls over and over again until they were empty, and then I was spurting gushes of clear liquid as if I were squirting.

“It felt good, Seita……♥”

　After a long ejaculation, he finally let go of my lips and looked down at me. He stroked my hair, which was now wet with a lot of sweat, as he held my limp body close to him. I had grown tired of seeing the face, which I should have gotten used to. But now, I can't help but love the bearded face. I want my uncle to love me like this for a long time to come. I want to keep loving 【Daisuke Sugaya】──.

“Daisuke……♥♥”

　I called out to him in a rapt voice and began to gently serve him with his big cock in my mouth, which had been pulled out of my asshole and was covered in semen.

“Sorry to keep you waiting, Daisuke!”

　Daisuke, who was already completely naked in the changing room, turned a reproachful glance at Seita, who had arrived late. He had already a boner in anticipation of the fun he was about to have.

“You're late, you know…… Come on, let's get on with it!”

　He said so while hiding his excitement and pretending to be disgusted, and then he quickly opened the bathroom door and went inside. He then poured a tub of hot water over himself and immersed himself in the bathtub, waiting impatiently for Seita to 【undress】.

　After that incident, Seita wanted to be like Daisuke more and more and joined the rugby club, and because of that, he had a great physique that was incomparable to other boys his age. Seita's face also became more masculine and fearless. Even so, he still couldn't compare to Daisuke.

　Seita, who was soiled with mud, took off his sportswear and stripped naked, and at the end he held up the fingers of both hands on his back and took off the 【skin】.

“Phew! Huh~, the exhilarating feeling of taking off this hot and uncomfortable skin is always exceptional to experience……♥”

　Seita, who finally took off the 【skin】 and returned to his original body, stretched wide in the hot water fumes. Great stature covered with thick, large muscles. It was the body of 【Daisuke Sugaya】. Daisuke, who had been waiting for him, jumped out of the bathtub and jumped on him and covered him with his big body.

“Ohhhh~~♥ Seita──, or rather Daisuke♥ Hurry up and put your big cock inside my asshole♥♥”

　Daisuke whispered to Seita, breathing hard. He was looking at the naked body of a man who was like a twin to him. The thick muscles that cover the entire body and the body odor of a middle-aged man covered in sweat from his workout. And the most noticeable thing is his huge cock, which is both erotic and uniquely male. It is the most lewd and sexy thing to see his cock erected to its maximum and warped to the point that it touches his abdominal muscles.

　A familiar cock, a familiar body, and a familiar face. A man who looked exactly like himself, as if he had just appeared from inside a mirror. Daisuke smeared body soap all over his body and placed Seita's thick body on top of his own. Then, as if they were caressing each other's bodies with their whole bodies, they began to rub their slimy, body soap-soaked bodies against each other. The feeling of the same shaped glans rubbing against each other's belly, and the feeling of two identical cocks pressing strongly against each other, was so pleasurable that it made Seita feel dizzy──.

　Seita, too, was absorbed in the sensation, rubbing his own body against Daisuke's. He has a manly body and hairy skin, just like his uncle, who is a giant of a man. Unlike Daisuke, who longs to be fucked by someone bigger than himself, Seita found the most pleasure in violating his uncle's body in this way, when Seita is in the form of 【Daisuke Sugaya】.

“I know, I know. I couldn't wait either, Daisuke……♥”

　Seita, unable to hide his excitement, took Daisuke's body in his arms and pushed him down onto the tile floor of the bathroom. He then covers Daisuke with his snorting and places his cock into Daisuke's open anus as if waiting for him. Seita's cock, already soaked with pre-cum, slid into his uncle's asshole without resistance.

“Ohhhh, you're so good♥♥♥”

　Daisuke, who had been waiting for his moment of lust, clung to Seita with a wild cry.

“I'm so proud of my asshole. I haven't even gotten used to it, but it loosened right up♥”

　Seita's hips began to move slightly as his cock was fully inserted into Daisuke's asshole. Daisuke's mouth was filled with a pitiful gasp every time the thick cock rubbed the folds of his intestinal wall.

　They had the same cocks, the same bodies, the same faces. They look more alike than twins, and they have sex while looking at each other's faces as they feel each other's cocks in and out of their assholes──. This perverse sense of immorality invades Seita and Daisuke's psyches and arouses their lust even more.
