A story about a man and a woman who switch places and go crazy every time they have sex. Tsundere male/female version. (Pixiv Fanbox)

You've got to be kidding me! You're the one who needs to stop joking around!" Two men and a woman are quarreling in the classroom. In the classroom, there are a few people sighing as they watch the exchange. The exchange is not something special, after all, it's something that happens all the time. It is nothing special. His name is Shingo Todoroki. Her name is Sumire Akitsu. She is a second-year high school student, and he is in the same class with her. They had been childhood friends since elementary school. It is safe to say that their relationship is inseparable. But recently, when they see each other like this, they are always quarreling. The teacher came in and said, "Yes, yes, the chime has rung, so get to your seats quickly." The teacher came over and stopped their quarrel. Their fights were always trivial. People around them called it a lover's quarrel. Shingo was annoyed by such comments. But even so, Sumire is cute, isn't she? I've been with him since elementary school. I don't feel anything. Shingo assured me. Shingo said, "But, Shingo, you might even like Sumire, don't you? What? It's not possible, and I've already said no to him. Sumire also said no. The two of them ended their usual school life together, answering to the agitations of the people around them without any hesitation. Many of their classmates were still cold to the two as they argued with each other. It was after HR one day that an incident happened to the two. It was by chance. Sumire went to the classroom. Shingo went to the hallway. As the two friends were talking to each other, they did not look ahead and collided with each other vigorously. Because of the bump on the head, both of them were knocked unconscious for a moment, and when they came to, they were in the infirmary. Ugh, headache. ...... Sumire wakes up. The first thing that comes to mind is the fact that the first time you see a person in your life, you are going to be surprised. I remember that suddenly ...... that guy bumped into me, and it was bad. The most important thing to remember is that the best way to get the most out of your health insurance is to get a good insurance policy. The most important thing to remember is that the best way to get the most out of your money is to be prepared to pay for it. She had shoulder-length black hair, and her breasts were large enough that she could feel their presence. If you look at her chest, you will see a flat chest ......, and if you look at her arms, you will see that they are clearly thicker than usual. Violet, for a moment, without realizing what had happened, got up from the bed in a state of panic and jumped out of the curtain-covered bed. What is this? What the hell! At the same moment, Sumire turned around at the sound of a voice she heard. There she found herself. She had a panicked look on her face, but she had long hair, bright eyes, and thin white arms on her chest that were visible even in her school uniform. Me? Me? The voices that mouthed to each other were that of a man and that of a woman. Clearly not right, Sumire turned her gaze to the life-size mirror that remained in front of her. And there, Sumire's image, which had clearly turned into Shingo, was reflected in the mirror. Aaaaahhhh!" Thank goodness the infirmary teacher wasn't there. ...... would have caused a huge commotion if she had been there. Anyway, they were told that it was a mild concussion and that he was going to the hospital and that he would be out of school the next day for a serious condition, and they were on their way home. They would be going home from school together for the first time in a long time. On the other hand, if they had friends, they would have had to pretend to be the other person, so it would have been nice to avoid such a hassle. 'Why is this happening to me ......?' That's my line, of all people, with you. That's my problem! Why should I switch places with you? It's not my fault! And don't yell at me with my body! You don't talk to me like a woman in a man's body! You're a loudmouth! I don't have a choice! On the way home, they continued to bicker and quarrel, and eventually made it home. The two childhood friends lived next door to each other ......, so they had to see each other even if they didn't want to. I'll kill you if you do anything with my body! What? I won't do it! Anyway, don't say anything weird in front of ...... mama! I'll be back in the morning to do your makeup and stuff, so just wait until then! I'll do that. You're the one! Don't talk to my parents in that woman's tone! I know, I know. ...... I know." All right, well, I'll see you later ...... Gohon, I'll see you later." The two went back to their respective homes, pretending to be each other. For both of them, each other's home and parents were familiar figures, as they had known each other since childhood and had often visited each other in the past. It was a familiar sight. Ojamama......I'm home." Hastily correcting his words, he finished greeting Sumire's parents and rolled into Sumire's room as if to escape. Closing the door, I exhale heavily and look at Sumire's room. The atmosphere of the room has indeed changed from the past. It was girlishly clean and tidy. I wondered what I would do if the room was dirty, but being Sumire, I wasn't too worried about that. She's always been a firm believer, and she used to scold me ......, which was a pain in the ass. Sumire put her bags on the desk and collapsed into bed. The first thing that you need to do is to make sure that you have a good understanding of what you are doing and how to do it. Your imitation won't last forever." I couldn't stay in my violet uniform. Shingo began to take off his shirt without any particular concern and became a violet. It was insensitive in the same sense as when I was a man. Ugh. ......" Violet's breasts are exposed when she takes off her shirt. "When did this guy get so big ...... and aren't they too big?" It was just out of simple curiosity. But there is no one who does not understand the interest in the body of the opposite sex. The hands that had been touching them through the white bra soon began to rub them, as if seeking their soft touch. 'Oh no, oh no, ...... I have to stop doing this, but ...... my hands just won't stop.' The rubbing up of her soft breasts gradually made her body hotter and hotter. And it becomes frustrating to wear only a bra. Her large breasts tremble as she removes her bra. White breasts that cover my view of myself. I reach out to the nipple at the tip of it and touch it with my fingers. I'm so sensitive. Ha, ha." Shingo had become absorbed in Sumire's body. He continued to crush her nipples with his fingers, stimulating them, and exhaled hot breaths from his mouth. His body became hot and sweat poured down. The more I rubbed her breasts, the stronger the stimulation and the more pleasure I felt. "Oh, men don't feel this way. Then, it may be natural that interest is directed to places that men don't have. When she takes off her skirt, she can already feel the love juices running down her thighs. Shingo pulls down his pants as he does so, and the love juice overflowing from his secret place is threading down. He could feel this much just by squeezing her breasts and playing with her nipples. I guess Sumire's body is just so sensitive and dirty," he said to himself. Shingo, making excuses to himself, took off his pants and reached his fingers to his wet secret place on the bed. If he strokes around the secret place, his body shivers with it. Shingo's vision was then caught by a noticeably puffy and swollen spot. Shingo, who had become a violet, reached out his finger to it and crushed it as if he were playing with a nipple. "Nnnn！！！！！！！！ Mmmm！！！！！！！." The stimulation to the pubic nucleus was something no man had ever felt before. He turned his back away from the intense stimulation that made it impossible to breathe, and his body convulsed. He managed to drop his back to the bed and exhaled heavily. I let out a huge gasp of air, "Haa, haa, what the heck, that was amazing!" From that point on, I couldn't hold back any longer. With the desire to savor the woman's body, he stroked her secret parts with his fingers while he was completely naked and inserted his fingers into the areas that were sloshing with her love juices. 'Nnnn！！！！.' Stimulation that makes it impossible to breathe. Still inserting his index finger, he stirs vigorously. The inside of the vagina tightens the finger so much that it hurts. But still, the heterosexual mind, with its strong desire for pleasure, violently makes Sumire's body wild with lewdness. Ugh! Kuhuuhuuhu! Uuuuuu!!!!" Her agonized cries do not cease. With her free hand, she rubbed her breasts and played with her nipples. Sweat overflows, it is the smell of Violet's sweat, and even the smell excites her. Shingo's mind and Sumire's body reach the same point as he violently fucks his own body. 'mmmmmmmm ！！！！！！！ Kuuuuuuuuuu!" Shingo and Sumire's bodies climax violently as their love juices gush out and they arch their backs on the bed. Their bodies convulse and their bodies are hot. I had never jerked off like this with a man before. And even though they had climaxed so much, their bodies were still on fire and begging for more. 'Soooo, wow ...... I've never masturbated like this before.' Shingo felt a sense of discomfort in his tone. It was as if he had experienced this kind of thing before. Shingo sensed that there was a memory in his memory that he had never had before. It was a memory that was different from the memory of Sumire's memory ...... that he knew. They had been flooded by the climax that had just occurred. Ugh! Wow, wow ......, what is this?" The memories of Sumire flowing into his brain mixed with Shingo's memories, confusing Shingo. Shingo managed to sit up, breathing heavily. 'Hah, hah......ah, I have to fit that guy.' Oh my god! Why, I've got to be his body! Sumire, the next-door neighbor, was in Shingo's room, muttering to herself in frustration. Her clothes had already been changed, and she was lying on the bed in her jersey. 'My bad!' With such a voice, a familiar face came into view. What, me? Yes, it's me, ...... Sumire Akitsu. No, you're not! You are Shingo! Why are you coming to my house without permission? The first time she saw him, she was surprised and pushed Shingo out of the way. Shingo, who has become Sumire, looks at her and points to the window. Their rooms are directly across from each other, and they are close enough that they can enter this way by telling the window. Shingo, who had become Sumire, sighed softly as he looked at her. You masturbated, didn't you?" Ha, ha! I don't think so! I'm not a pervert like you! "Hahahaha, you don't get it, do you? When I masturbate, I seem to be able to read the other person's memories and words and actions. You've been talking like me for a while now. "Oh, my God, you're lying? It's not possible, it's not possible, it's not possible. I've done it, too, so I guess that makes us even. I'm in the body of the opposite sex now, so I guess it's inevitable." You! You're saying you masturbated in someone else's body? That's disgusting! "Can you say that about someone else? I can smell the squid in the room. "It's because your body is so erotic that I can't help it. "Well, my body is pretty sexy too, but..." Of course it's because your mind is pornographic! So it's all my fault? That's right! Then, do you want to try it? Who is more erotic, Sumire or Shingo? Shingo as Sumire and Sumire as Shingo look at each other. Their minds are mixed up because they have masturbated to each other. The two become completely naked. Shingo is excited by Sumire's body, but Shingo is excited by Shingo's body that has become Sumire. Shingo was aroused by his own body, which is an unusual state of affairs, and the same was true for Sumire who had become Shingo. She was aroused by her own body, with her large breasts shaking in front of her eyes and the scent of a woman wafting through the air. She could not take her eyes off of herself, even though she was supposed to be herself. I wanted to suck on her breasts, insert my cock into her pussy and cum as much as I could. Ha, ha, ha, ha." Huff, puff, puff." The two men look at each other with glazed over eyes, bring their bodies close to each other, and put their lips on each other's lips. "Chuh, chuh, chuh, chuh, chuh, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm, mmmm!" What should have been a light kiss at first Gradually, the two of them were consumed by pleasure, and while holding each other's bodies, they pressed their chests against the other's chest. They grab each other's heads and start kissing each other so intensely that their faces are pressed against each other. Their mouths are covered in drool as their heads go blank. The memories of each other's bodies flow into their minds again. Sumire has memories of Shingo, and Shingo has memories of Sumire. "Puhaaaah! You're too desperate! You're kissing me! "Aren't you the one who's not good at it?" The tone of voice has been completely replaced, pulled by the memories of my body. But without even realizing it, the two of them turn on each other's genitals, as if they can't stand it any longer. "In truth, you're in the habit of liking me (me)! Nigihi? Hyahiiiiiiiiiiiiiiiiiiiiiiiiiii!" Two people who have come to know each other's feelings insert themselves aloud. A virgin and a virgin, Shingo's soul inside Sumire tightens around the male organ in search of pleasure despite the intense pain Sumire's soul, which had become unable to think of anything else due to the stimulation of the first penetration, shook her hips wildly and fucked herself. I can't feel it! Aaah! Aaahhhh! Oh oh oh! Oh, oh, oh, oh! Oh oh oh oh!!!!" The two in agony were already unable to think of anything else, and just fucked their former selves in front of them. And then, in a blink of an eye, they both climaxed and ejaculated. "Oh, I'm cumming! I'm cumming! I'm cumming! Love juice and semen are expelled. The body spasms, breathless from too much stimulation, and stretches its arms to the back of the sweaty partner to make its body close to the other's. The body is covered in sweat. They lost consciousness as they held each other's bodies as they poured and were poured semen into each other. When they were childhood friends, they were really close. But as time went by, people around them started to clamor for the man and woman to be together. The two became estranged. However, their feelings for each other remained unchanged, and they communicated their feelings for each other by bumping into each other. By switching places, they were able to get to know each other's feelings. They were able to know each other's feelings. Me? Oh, me?" They looked at each other. It was a sign that they were back together. They stared at each other's close-up faces, still inserted, still inserted. Then, all at once, the memories of Sumire and Shingo flowed into their minds. It was not that they had been replaced, but that they had returned to their original state. However, there is nothing but discomfort in their bodies. It should be my body, but I have the feeling that it has become the other person's body. It is the effect of a mixture of spirits, but there is nothing I can do about it. 'Oh, it's my body, but it feels like it's not mine, ugh, my cock, it's tightening inside me. "Nnhee! It's not my body, but it feels like it's not mine, my pussy is clamping down on my cock. The two men exhaled loudly and pressed their lips together again. Then they began to shake their hips again. "Nnnn! Mmmmmm! Mmmmmm! Mmmmmm!!!!" As they writhed and writhed, their egos were being restored in their heads, in their brains, in their brains, in their brains. But on the other hand, the other's emotions, aroused by the body of the opposite sex, also remain firmly in place. （My body is so hot! I want to fuck you more and more!) （Oh, they're fucking me with my body! I'm being fucked by my body! I want him to fuck me more!) The body, which had just ejaculated, was sensitive and could not endure the overly intense pistons. 'Mpuhaaaah!!! Ahhhh! Aaah! I'm cumming! Nnnggghhhhhh! Ohhhhh! I'm cumming! I'm coming, I'm coming, I'm coming, I'm coming, I'm coming! Ohhhhhhhhhhhhhhhh ！！！！" As they splattered with copious amounts of hot semen. Their vision goes blank. Then again, they open their eyes to the stimulation of the dripping semen. The two men open their eyes to the stimulation of another dribble of semen. No, no, go back, ah, I don't know which is which." And their hips don't stop. "N-n-n-n-n-n-no! Oh, I, I, which one am I? I, I, wa, I don't know hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii!" "Nnghhhhhh! I don't know if I'm Sumire or Shingo! "Giggity, giggity! I'm going to ejaculate again! I'm going to ejaculate again! I'm going to ejaculate again! I'm gonna cum again! Cum in me, cum in me! "Ohhhhhh! I'm cumming! I can't stop cumming! I'm going to impregnate you with my cum! "Oh, oh, oh, my womb is full of my cum! But I want to have sex! I want to have sex! They fuck each other, no longer knowing which of them is which. The fortuitousness of their lovemaking never seemed to end.
