While her husband is away on a work assignment, Ayako Inoue is overwhelmed by household chores and parenting, enduring daily stress and sexual frustration. One day, she is invited by her son's friends and, almost forcibly, drawn into a sexual relationship. Initially trying to resist and maintain her composure, she gradually loses herself to the strong, youthful bodies and erect penises of the young men. From above and below, drooling and surrendering completely, she discovers the pleasure of being a sex slave, giving in entirely to her uncontrollable desires. In that moment, there's no turning back for her heart.
