Saki is troubled by her son's impending adolescence (her stepson). Lately, he's been frequently buying questionable adult products online. Peeking through his bedroom door, she discovers him intently caressing a delicate sex doll, a chilling sight. Then one day, his homeroom teacher visits with a female student. Her son appears to be stalking and groping her. Saki believes that if this continues, her son will become a sex offender and tries to persuade him. "You can touch Mommy's breasts instead," she suggests, offering her body as his sex toy to curb his rampant lust. "This isn't intercourse...it's just helping my son relieve his sexual desires," Saki says. She accepts his erect penis, becoming his object of sexual gratification—this is her frantic daily routine.
