Mother Azusa lives an ordinary life devoted to housework, yet she becomes acutely aware of her son Shinji's lingering gaze. He constantly stares at her, lost in fantasy. Her husband also watches her intently, hungrily, and Azusa herself harbors a deep desire to be leered at. Delighted that her unfaithful husband has finally turned his attention back to her, she eagerly indulges in sex after a long dry spell. The next day, while cleaning Shinji's room, Azusa feels her body respond to her son's intense stare—and gives in to temptation, seducing him. Beneath the surface of everyday life, hidden desires stir.
