Adult performers portray an aunt-and-adult-nephew role-play. Maiko has gone without sex because her husband's libido has faded, leaving her increasingly unsatisfied. Then her womanizing adult nephew Kentaro visits. Sensing her frustration, he uses smooth talk and practiced hands to exploit her pent-up desires before forcing her down. Kentaro keeps returning and persistently pursuing her. Maiko tries to reject the shallow affair as a momentary mistake, but her body craves the pleasure it has finally experienced again and continues to let itself be swept along.
