Sumire Sonozaki, 40 years old. Her married life with her husband, who was once her childhood friend, has lasted 18 years—but what began as love gradually slipped into routine, and before she knew it, they had entered a period of stagnation. Amid this emotional and physical distance, her sexual dissatisfaction grew stronger each day. To address it, she made a bold decision: under the condition that her husband would leave the house from 2 p.m. to 5 p.m. on weekdays, she would seek new pleasure during those three hours. To ensure she could lose herself completely in ecstasy before her husband returned, the entire production team worked together to create a special filming schedule designed to maximize her orgasms. This is a unique, intense experience, crafted to unlock her deepest passion and pleasure within just three short hours.
