Synopsis
Sayuri lives in a two-family home with her daughter and son-in-law. While working as a full-time housewife, she occasionally does swimsuit modeling through a referral. One day, she discovers her son-in-law Kunio engaging in a private act using her worn swimsuit. It turns out his impressive manhood has been causing problems in their marital life. Captivated by his endowment and convincing herself it’s “for her daughter’s sake,” Sayuri relentlessly tempts him day and night. Unable to resist her seductive advances, Kunio succumbs to her persistent allure.
