Eriko, who has been remarried for three years. Her stepson, who lives with her, worries and cares that she still can't lose her virginity. When she visits his room, her mother-in-law approaches her saying, "I have to get used to women...". She glances at her upset son as she rolls up her skirt and begins to masturbate to her. And when she sees it, she holds her son in her mouth who has swollen up, and sucks her son with an obscene tongue while making her throat sound. . Sex education for such a super-excessive protective mom.
