Yoshie Mizuno, a 50-year-old housewife, lives alone with her husband's stepson while her husband is away on a long business trip. Her stepson is fascinated by Yoshie's large breasts, thick pubic hair, and ripe honeypot, and frequently sneaks into her bedroom to devour her body. Frustrated by her husband's absence, Yoshie accepts his twisted desire and shares a passionate kiss in a forbidden sexual encounter within the family. The thick, strong cock of her stepson, which she touches for the first time, revives her womanhood, and she lustfully and violently shakes her hips in a pleasurable raw creampie sex session.
