Yoko Mitsushima, a 29-year-old married woman entering her third year of marriage, makes her AV debut. Feeling that her sex life with her husband has become too routine and lacking excitement, she decided to enter the adult industry to fulfill her long-held desires of experiencing multiple partner play and unconventional, thrilling scenarios. As her smooth, sensual body is teased and stimulated in various ways, she lets out lewd moans while gushing squirt after squirt, reaching climax repeatedly. She indulges in fantasies come true—toy play and blowjobs in a bar restroom, sexual encounters inside a moving bus—losing herself to the intense thrills and pleasures unattainable in daily life. Taking her first step into a new chapter, Yoko opens the door to a new life, satisfying her long-suppressed desires.
