Mari and her husband finally achieve their dream of owning a home. Eager to rekindle their intimacy in their new bedroom, Mari is disappointed when her husband's penis fails to respond. Frustrated and full of pent-up desire, she begins masturbating during the daytime. Unaware that the local greengrocer has been secretly watching her, he takes delivery as his excuse to enter the Aoi residence and forcefully seduces her. Though she initially resists, Mari gradually succumbs to the older man's experienced sexual techniques, eventually giving in completely to his allure.
