"Pranks by male students at work and my father-in-law... I want to feel that thrill again..." Middle-aged married women who secretly accept outside cocks behind their husbands' backs. Sayoko is 52 years old and 18 years into her marriage. During her student days, she was molested by college students at her part-time job, leaving her with fear and trauma, preventing her from experiencing teenage romance. Her first time was at 24, and her relationships with men remained limited afterward. Even after marriage, sex was infrequent due to lifestyle and circumstances. Always left unfulfilled, her life took a turn when her father-in-law, who became physically disabled and required care, began touching her buttocks and fondling her genitals. She felt intense excitement alongside deep guilt, and continued the acts until his death. Unable to forget that secret pleasure, Sayoko decides to appear in an adult video. A mature married woman's story of embracing a new path through taboo experiences.
