Ivu Yumeshiro, a masochistic woman driven by extreme desires, has experienced countless fleeting pleasures before finally being led to her master's domain. Her body is constantly consumed by sexual fantasies, so sensitive that even the slightest stimulation sends her into overwhelming orgasms. Seeking to perfect her beauty and embrace her ultimate masochistic femininity, she underwent cross-dressing and hormone therapy, gradually transforming her body into a more feminine form. Driven further by her obsession with aesthetic perfection and the ideal look of a humiliated female slave, she adorned her body with lewd tattoos and pierced her nipples and navel. Though the process brought intense pain, she embraced the agony as part of her rebirth, claiming that the pain itself had transformed into pleasure. Through repeated exposure to the pain of tattoos and piercings, along with relentless masochistic fantasies, the pleasure of submission became deeply engraved in her mind. Upon entering the hotel, even without removing her clothes, her penis is already erect, oozing pre-cum and slick with wetness. Merely tormented by words, Ivu Yumeshiro experiences intense brain orgasms, her eyes bloodshot and rolling, climaxing again and again without end.
