Three married women who desire affairs and have volunteered to appear on the show. Yūko feels she is still at the peak of her femininity; although she feels guilty toward her husband, she longs to experience infidelity at least once. Her charm lies in her elegant, graceful smile and her prominent F-cup breasts, noticeable even through clothing. What she seeks is intense sex where she is thoroughly pleasured. Meanwhile, Aya, aged 45, desires a younger man with a large penis and wishes to have an affair. Since her husband has a small penis, she wants to experience sex with a younger man, even just once. Lastly, Mio, who has been married for 12 years, dreams of indulging in passionate three-day affair sex right in the bed she shares with her husband. Each woman carries her own desires and struggles, building up anticipation for their forbidden encounters.
