【Request】 Human experimentation: Sensory shared sexual intercourse between a man and a woman. (Pixiv Fanbox)

Welcome to my lab." In the darkness, a lone girl in a white lab coat appears. A breathtakingly beautiful girl with long straight hair, doll-like elaborate facial parts, and cold eyes. Her name is Gion Renka. She is a brilliant woman who, despite her high school age, has inherited the Gion Zaibatsu with exceptional talent, ability, and ambition. She has been conducting various researches in its underground facilities while running the school. Adolescent boys and girls are her perfect research subjects. That is why there is no shortage of subjects for her human experimentation. And today, she is alone ....... One girl opens her eyes as a glaring light shines from the ceiling. He squints against the dazzling light and tries to get up, not knowing what to do with his current state. But his arms and legs were chained, and he could not move. Feeling the sound of metal clashing, the girl exhaled heavily as she realized that her body was immobilized. Her current state was that of a completely naked figure. Full breasts, large buttocks, round face, and long brown hair. She had a body that would arouse the sexual desires of any member of the opposite sex. She said, "Someone is watching you, aren't you? What are you going to do with me like this?" The girl murmured in a calm voice. If you were going to kill me, you would have done it by now. But the fact that you don't do that means you want me to do something ...... like that, right? Someone who has a grudge against me told you that? Sure, I'm not a person people admire, and I've done some bad things. But there's a reason for that. I don't know what it is about you that made you lock me up here, but if you talk to me, I will help you. There is no point in humiliating me here ......." Before the girl spoke plainly, the sound of an audio switch being turned on in the room echoed. 'Subject 219.' The voice belonged to a woman. Chika Moriyama, age 16, parents are foreign bankers. Her parents are foreign bankers, and she has a history of prostituting female students because she can afford it. Since the student reported the prostitution, the experiment was deemed appropriate. I see. You are trying to get revenge on me for prostituting you? I don't think it's a good idea to do that to me. I have all the personal information about the children in your family. If anything happens to me, I wouldn't be surprised if something happens to them. If anything, there will surely be misfortune for your family as well." The girl ...... Chika Moriyama speaks with a relaxed expression on her face. Therefore, it is only natural that he is prepared for this kind of situation. In fact, he had a bodyguard who used some of the money he made in the prostitution business downtown, and he also had a person who specialized in revenge. If they didn't hear from him, they would take revenge, in a variety of ways. I'm sorry ......, but my family isn't here." Chika turned around at the sound of a voice coming from the side that was not audio. There she was, a beautiful girl in a white coat with cold eyes and long black hair that was dominated by her long black hair. And the look on her face reminded Chika of something. The only daughter of the head of the Gion Zaibatsu, Gion Renka. She said, "......The feeling that you are in an absolute position is because you don't understand the other person's feelings. You, who always think things from the highest point of view, don't need to know the feelings of a woman who is prostituting herself. You are wrong." "......" Chika breaks out in a cold sweat. The other party is the head of one of the world's leading conglomerates. The power of money is not even close to my own. The police will not even act when you kidnap yourself like this. He was not someone with whom he could negotiate and win. In business, you have to stand in the shoes of your subordinates in order to grow. I appreciate your advice, ......, but what do you want me to do? I would be more than happy to work for your company ...... "I'll make you understand what it's like to be a prostitute." What are you talking ...... about?" The lotus flower pulls out a syringe right in front of him. The syringe is filled with some kind of liquid, and then she pushes it against Chika's arm. He then pushes it against Chika's arm. Don't! Doing this to me won't help! Please! Stop it!!!!" Chika tries to resist, shaking her body from side to side in agitation, but it is pointless with her restrained body. Chika's face shows a look of despair as she is injected. When the syringe is pulled out, drowsiness overtakes Chika at once. She says, "Oh, oh ......, help me, I need help. Then, Chika's consciousness was swallowed by the darkness. The next thing she knew, her body was hot. It was not that the room was hot. It was not that the room was hot, it was just that when she had a fever, she would feel this way. ...... In short, it was a sensation of heat in the core of her body. Sweat is pouring out of me, and I'm breathing hard. My uterus is tingling. The secret place had already begun to overflow with love juice. "Haa, haa, na, what, what is this? What's going on! Chika's voice was upset. The voice in his ear. "Woo hoo hoo ......" The lights that had been shining from the glaring ceiling are turned off. This allowed Chika to see a man approaching towards him. It was a man ...... named Yugo Akiba, a fellow prostitution manager and bodyguard. He was approaching us with a screwed-up look in his eyes. Yu, Yuugo! I! Chika! Help me! Sex, sex, sex ...... I can't hear you! Please take off this chain! Chika screamed, but Yugo didn't listen to her at all. He points his erect male organ at Chika. He held Chika's mouth while she screamed, and then he thrust his penis into her mouth. "Nnnnggg! The male organ was forcibly pushed into her mouth. Suddenly, she was startled and tried to resist by shaking her head from side to side. Then, intense stimulation surged from Chika's lower body. What the hell is this? What is that? While Chika was unable to understand what was happening, Yugo started to fuck Chika's mouth with his hips. The saliva and the juice of the tip of the penis spread into her mouth. Chika is trying to resist the uncomfortable sensation. The sensation of something sensitive being violently stimulated by something warm and fresh was surging through Chika's lower body. Nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn! Nmbuch! Nnnngggg, chuppah, ahhhh, nnngg!" Chika's hips were shaking as the pleasure surged through her lower body. She was unable to resist the male organ being thrust into her mouth. Once the tongue stimulated the bell mouth, the sensation of the tongue licking the sensitive spot surged from Chika's lower half of her body. "Mmmph! Nnnnggggggg! Nnnggghhhh! Chika guessed it right there. The stimulation to the male organ that Chika is now sucking is bouncing back to her body. She was now experiencing the stimulation of the male organ being forcibly forced into her mouth. Chika was surprised at the situation, but was unable to resist. If she bit the male organ, the pain would be overwhelming to her. However, if he was still being raped, he would be ....... The thought is going around and around, something is rising up from the urethra of the male organ that Chika is sensing. "Mmmmfuh！！！！." It is definitely semen. The most important thing to remember is that you should not be afraid to take a look at the pictures. Chika tries to spit it out, but the male organ, which she does not have, is tingling with the need to cum. How good would it feel to spit it out in this warm, raw place? Chika was rocking her own hips, and was being consumed by the pleasure of a male organ that she never had. Then, she released her semen. A large amount of semen was poured into her mouth. The first thing to do is to make sure that you have a good idea of what you want to do. The warm mouth was filled with a large amount of semen, and the smell of the man in her mouth was so strong that she could not stand it. She felt her mouth filled with the scent of male semen. 'Puhaaaah! Oh! Goho-goho, oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh." He spits out the male organ from his mouth and spits the semen out of his mouth. The semen is still spewing out from the male organ, and it is shooting out onto Chika's face. She said, "Oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh. Chika exhales heavily, spewing semen from her mouth. The sensation in her body is shared. Chika, still unable to move her body, feels the sensation of something hot pressing against her secret place, and then the sensation of the female genitalia pressing against the sensitive glans of the male organ. Then, the sensation of the female genitalia pressing against the sensitive glans of the male genitalia hit her. Nnhyah!!!?" When she looked at him, she saw that Yugo was pressing his own male organ against hers and was about to insert it. Chika shook her head from side to side. She does not know what would happen if she were to be inserted into her own female genitalia while she is still feeling the sensation of the male genitalia. She would be subjected to both male and female stimulation at once. Stop it! Stop it! Yugo ignores Chika's raging voice and continues to grind and press his male organ against her. The male organ is pushed into the wet female organ and begins to insert itself into her. I can't feel my cock, I can't feel my cock, I can't feel my cock! My cock is in my pussy! Chika, who had been subjected to sensations from both sides, was beginning to feel as if she were fucking herself. She pushed the male organ into her own secret place. She could feel the sensation of the vagina. Moreover, that vagina is unmistakably the sensation inside her own vagina. I felt the sensation in my own vagina. I, I, haa! My pussy! It's so tight and narrow. My cock is so thick and hot! I was pushed into the male and female genitalia by myself from behind as well. I'm being fucked and fucked like I'm being made into a sandwich by myself. I'm going crazy. I am being fucked by myself while I fuck myself. After all, I can't stop it. The movement of the male organ that is raping and being raped by Chika becomes faster. He pushes in hard and hard, and is pushed in. "Hiiii! Hyah! Aaah! My, my, my pussy is soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo! Whoo! My cock is raping me! The intensity of the sensory sharing was so intense that the lower half of her body was out of control, and she was shaking her hips anyway. Despite the fact that I was being raped, I kept shaking my hips, trying to fuck my own vagina with the sensation of being raped. Eventually, Yugo, who was fucking her, covered Chika, who was being restrained, while He grabbed both of her ample breasts with his hands and squeezed them hard. Hyaaaaa!!! I'm squeezing my own tits! They are so soft! Aaahhh! It's so hard! I'm squeezing them so hard! I don't know whether I am being fucked or being fucked. Since I have experienced both, my mind is confused. But this is only going to be spurred on by Yugo's actions. While shaking his hips, Yugo grabs her breasts and rubs them up and down. While violating Chika's secret place with hard pistons, he brings his face even closer and takes her lips. As I do so, I find myself in a situation where my tongues are entwined with each other in Chika's brain. 'Nnnnnn! Nnnnnn!!!!!!!" Chika senses that both of her tongues are hers. She cannot do anything about it by her own will. She was just enjoying the pleasure. Her hips would not stop and she was in a state to fuck herself. Chika squirmed with the unusual perversion of fucking herself, kissing herself, and rubbing and being rubbed by her breasts. At the same time, Chika clamps down on her own male organ. "Nnnnggggg!!!!!!!!!!!!!!!!!!!!!!!!!!!!" The sensation of her own male organ clamping down causes it to spurt out semen all at once. The semen he produced poured into his female organ. 'Nngummmmmmmm!!!!!!!' Chika fucks herself, her body trembling as she is kissed. （No, no, no, no! No more, no, no! (Nnhaaah!!!) (Oh, my pussy, it feels so good to be fucked by my cock!) (Nnghhh!!!! My, my tits are so soft!) （I'm fucking you! I'm fucking you! I'm fucking you!) （I'm raping you! I'm raping you! I'm raping me!) The mind is divided between the self that is being raped and the self that is being raped. But it is the same thing as long as the sensory organs are shared. （Wow, I'm being raped! I'm being raped......! I'm being raped right now! So, more and more, hin! Don't fuck me! No more. I don't want to be fucked any more! I want to be fucked! I want to fuck you! Please don't fuck me no more, please don't fuck me no more, please don't fuck me no more, please don't fuck me no more! Don't stick your cock in me no more! Ohhhhh! Fucking with a cock feels so good! Don't make me feel better, don't make me feel better, don't make me feel better, don't make me feel better! Oh, God! I'm going crazy! I'm getting fucked, I'm getting fucked! Aah! I don't know which is which! Are you fucking me? I'm being fucked! Ohhhhh! Oh, someone tell me! Tell me! Yeeeeeeeeeeeeeeeeeeeeeeeeee! Yiggle! Cock-iggle! Cunt-iggle! Oh, oh, oh! Which one am I? Oh, oh, oh, oh! Igg! Hiii! Hyaaaaaaa!!!!) Chika continued to be raped in the hell of sensory sharing, not knowing where she was.
