Newlywed Aina is troubled by the advances of Oki, the single middle-aged man next door. One day he forces himself on her. She tries to erase the violation by initiating sex with her husband, but he rejects her. As the days pass, memories of the physical pleasure overtake her anger and her frustration reaches its limit. She finally opens Oki's door herself, knocks the sweaty older man down, and licks him all over. On a scorching summer day, they fuck again and again until her husband returns at 7 p.m.
