Airi, who has become sexless with her much older husband, one day invites a man from the neighborhood into her room. She makes him drink coffee laced with her husband's sleeping pills and restrains his hands. The young wife, dressed in erotic lingerie, eagerly clings to his revived penis, pressing her plump buttocks against his crotch, and stimulates him with unfamiliar anal sex. Without using a condom, she inserts him raw. Savoring the long-missed sensation of a real penis, she selfishly sways her hips, and in the end, the depraved young wife unleashes a wild, intense service inside.
