Saki is worried about the education of her son (in-law) who has reached puberty. Lately, he seems to be frequently purchasing some kind of questionable adult goods online. When I secretly peeked through the door of the child's room, I found it eerie that she was seriously stroking an elaborate love doll. One day, the school's homeroom teacher visits with a female student. The son apparently stalked the girl and groped her breasts. Saki convinces him that if the situation escalates any further, her son will definitely become a sex offender. ``Please rub your mother-in-law's breasts instead.'' He suggested that she use her own body as a masturbator in order to suppress her out-of-control sexual desire. ``This isn't sex...I'm helping my son masturbate.'' Saki's mother accepts his erect cock and sexually processes it.The crazy daily life of Saki's mother.
