Shinji reunites with college friend Yuji, who married several years ago and boasts about his beautiful wife Nanami—an excellent cook and enthusiastic lover. Invited to their home, Shinji forms a plan in front of his friend's gorgeous, libidinous wife: prove that he is more virile than her husband. He secretly returns, pushes Nanami down, and launches into insatiable sex. Though she initially resists, she is driven into orgasm again and again.
