A 30-year-old married woman without sex, Airi Kosaka, attends an interview to join the "Perverted Club." The only membership condition is to be "perverted." After successfully joining, Airi spends her days engaging in perverted acts with the male members. Experiencing various plays with the club's owner, a super virile man in his sixties, a disgusting guy obsessed with cunnilingus, and a married man who loves masturbation, Airi gradually blossoms into a true "pervert." Becoming unrestrained in her sexuality, she eventually lures her husband into the "Perverted Club" and exposes her own shameful behavior.
