Ruri, a wife who seems to be panting in the middle of an affair. My husband was peeping at my brother who lived with me and showed a dissatisfied look. After her husband went out the next morning, Ruri makes flowers bloom in erotic talk with her brother. My brother, who sees that Ruri is not satisfied with her husband, attracts Ruri's interest by giving her a toy. My brother, who was watching the repeated masturbation with the toy he got, was thinking of inviting his friends to get absorbed in it.
