Midori was a beautiful young man who ended up with her master after repeatedly experiencing the orgasms of sex with a masochistic female. With an extremely strong sexual sense, Midori was always immersed in sexual fantasies, and even the slightest stimulation would cause her to orgasm uncontrollably. She began cross-dressing and hormones to perfect her female form, which transformed her body into a more feminine one, but in her quest for more beauty and the appearance of a masochistic female, she got a lewd mark tattoo on her body and pierced her nipples and belly button. It was very painful, but she accepted the pain of being reborn, and before she knew it, the pain became a pleasure. The pain of the tattoos and piercings, and the repeated fantasies of masochism, had clearly burned the joy of masochism into Midori's brain. When she stood before her master, she seemed completely out of breath. His eyes are bloodshot and he looks as if he is about to burst into tears. Midori has not yet received any training, but he is already on the verge of orgasm. The beautiful boy, who is dominated by the masochistic female in his brain for 24 hours, turns any way he is tormented into pleasure. When a Frisk is forced into his vagina and then plugged with an anal plug, he screams and twitches. And when a penis is inserted, he lets out an ear-splitting, intense moan. Even after a generous amount of semen is poured into his vagina, his whole body convulses as his hot, erect penis is stroked, and he cums multiple times, squirting from his glans, but it's not over yet... In response to his master's voice, his whole body convulses, his vagina erects, and he screams again in ecstasy. Midori's 'brain orgasms', immersed in a fantasy, continue endlessly.
