33-year-old Ai married her husband at 29 and became a full-time housewife. Due to her husband's frequent business trips, their lives gradually drifted apart. With no children, she found herself with too much free time and began searching for a new purpose, eventually discovering the world of nude figure modeling. She realized she felt pleasure in being seen naked, which led her to step into the adult video industry. Keeping her work a secret from her husband, she felt guilt at first, but the thrill of doing something forbidden quickly overpowered it. Craving the excitement missing from her dull marriage, she allows herself to be taken by a stranger she meets on a trip. Writhing in pleasure, she continues exploring a new path in life.
