In her third year as an AV actress, Miyuki Hourai experiences her first restrained chair session, revealing her raw, uninhibited sex. The moment she sits in this chair, she enters a trance state, losing control of her body. Drenched in cum and overwhelmed by intense pleasure, she experiences her first on-camera pissing. Despite exploding with humiliation, she orgasms honestly and repeatedly, becoming a pure, shame-filled pleasure doll.
