50-year-old Masako Ota. Mother of a young boy, 25 years into marriage, living her days as a full-time housewife. She has devoted her entire life to her husband, but one day, he told her "No, it's over," leaving her questioning everything she's known. While she understood that their sex life had gradually decreased with age, she never imagined it would become such a serious issue. After that, she endured days of loneliness and frustration—no matter how much she pleasured herself, it wasn't enough, and she grew increasingly restless, both physically and emotionally. Deep inside, a desire began to stir: to be taken hard and passionately by someone. What her soul now craves is intense, powerful sex that leaves her completely satisfied—not with just anyone, but with overwhelming fulfillment. To fulfill this deep longing, witness her debut in this powerful documentary.
