While Motoyuki is relaxing, his mother, Kumi, appears in a tank top after taking a bath. Motoyuki was shaken by the sight of her big nipples being visible through the sweat and steam, but Kumi didn't seem to care at all. After that, Kumi indulges in masturbation in her room. When I feel comfortable, I notice that Motoyuki is peeking. Motoyuki brings his erect crotch closer to Kumi who is panicking.
