In this adult role-play, Chiharu overhears her adult son and his best friend Kazuya talking about Kazuya’s virginity. His innocence and curiosity about sex bring her pent-up frustration and maternal urges close to the breaking point. When Kazuya visits while her son is away, she invites him inside and asks, “Are you curious about a woman’s body? If you want, I can teach you...” She begins his hands-on sex education with smothering facesitting before taking his virginity.
