Asahi runs a café with her unmotivated husband, who constantly slips away during business hours. With sales struggling, her only comfort is meeting the considerate, gentlemanly restaurant consultant Yasui, whose menu advice proves popular with customers. One day he invites her to dinner, but when she arrives, only his clumsy young adult subordinate is waiting. He tearfully begs her for sex and claims to be a virgin, so she gives in—only to discover that his skill in bed is anything but inexperienced as he makes her cum repeatedly.
