In her third year of marriage, Masumi is an ordinary housewife struggling with issues in her relationship. Her problem lies in her abnormally strong libido, which has led to a habit of cheating. She indulges in sex with a delivery man in her bedroom, and even has encounters while bathing at home—her daily life interwoven with strange, secret affairs. Hoping to release her pent-up energy and cure her tendency to cheat by having sex with a professional, she finds herself unable to stop, completely addicted to the pleasure. Depicted in intense detail is her wild, relentless fucking until she reaches physical exhaustion, climaxing repeatedly. Don't miss the sight of this seemingly average housewife, her beautiful F-cup breasts violently shaking, as she loses herself completely in ecstasy.
