Assuming that the husband is assigned to work alone and lives with two mothers and children. I'm trying to reach out to the lonely family environment of my son's classmate, Yuji, who has moved to the nearest neighborhood. Yuji, who was bullying his son at school, takes advantage of her kindness and pushes him down with desire. Having a physical relationship with his son's classmate, Yuji drives her further and plays with her. As her body continues to be developed due to repeated humiliation every day, her body begins to wet her crotch with secret expectations.
