Aiko is a beautiful wife that everyone envies. While her husband is on a business trip, her husband's subordinate comes over and forcibly approaches her, resulting in creampie sex. It was supposed to be a one-time affair, but Aiko becomes addicted to the sexual techniques that her husband does not have, and although she verbally refuses, her body is hot and desires the man, so she continues the relationship. Eventually, not caring that her husband is passed out drunk in the living room, she goes into the couple's bedroom and has sex with him, climaxing over and over again with an electric massager and a vibrator! A chaste young wife drowns in pleasure!
