Tired of their marriages and suffering from sexless relationships, these married women seek to fulfill their desires by sleeping with men other than their husbands. Each woman searches for her own special partner, experiencing a one-time forbidden affair. Keiko (44), married for 22 years and mother to a nearly adult son, desires sex with a man her son's age. Mina (34), married for 8 years, leads an ordinary life but craves intense, AV-style sex. Yayoi (35) fantasizes about being dominated by a muscular man, while Yūko (32), newly married for three months, grows jealous of her husband's infidelity and wants to reclaim her own pleasure. Aya (45) is unsatisfied with her husband's small penis and longs for a younger man's large cock. Mio (42), married for 12 years, engages in a deep, three-day-long affair right in the same bed she shares with her husband. Each woman's hidden desires and fantasies are expressed through adultery, becoming a personal challenge to satisfy their suppressed sexual needs.
