Masao returned to his wife's family's hot spring inn for the first time in a while. Her mother-in-law, Yuki, who greeted her, is a beautiful woman who looks good in a kimono, and Masao is fascinated by it. At night, Masao, who was watching Yuki bathing in the open-air bath, couldn't fix her erection, and asked her wife to play with her, but her lust didn't go away. And the next day, when her Yuki is taking a bath again, Masao finally attacks her. Yuki crossed her line even though she hated it. The next day, the two of them continue to have a relationship with each other.
