Incest has been practiced since ancient times, and it is said that in the nostalgic Showa era, especially in rural areas, incest was secretly encouraged by stepmothers, biological mothers, aunts, and cousins as a sexual rite of passage for men. Director Akuri Date has created a drama that has been meticulously recreated from a female perspective, starring six real mothers and stepmothers who have experienced incest, and six amateur mature women who desire to be raped and creampied by their young and energetic stepsons and nephews.
