A knock echoes in the couple's bedroom. The mother, who dotes on her only son, is asked to prepare a late-night snack for him during his exam study session, but in reality, it's to call out his mother to satisfy his desires. The son puts his hand into his mother's underwear, roughly penetrates her, and performs fellatio, ejaculating semen into her mouth. The next day, the mother, coerced by her son to give her husband sleeping pills, reluctantly complies due to her son's persistent demands and fear of being exposed by her husband. In front of her husband, who has been made to sleep in their bedroom, the mother is forcibly penetrated by her son's erect penis.
