The Enda family consists of a husband, his wife, and his mother-in-law. One day, the mother-in-law, Megumi, mistakenly buys an aphrodisiac cream thinking it's a beauty cream. Once something is bought, there's an urge to use it. Applying the cream to her private parts increases her sensitivity, making it impossible to suppress her desires. With no daughter at home now, she thinks it's safe... The mother-in-law takes her son-in-law's penis into her mouth and invites him into her mature vagina. Unable to resist his mother-in-law's cute and erotic body, the son-in-law ejaculates inside her. This unprecedented pleasure... The two can't forget it and keep having sex repeatedly.
