Nao, a suburban housewife, grows increasingly dissatisfied with her sex life with her husband, who only inserts and quickly withdraws. Trying to distract herself from her loneliness and frustration, her fingers gradually drift towards her overflowing, honeyed nether regions... Just as she reaches her peak, she feels a gaze and turns to the window to see an older man there. Despite the fact that he merely stumbled upon the scene by accident, his sincere apology opens Nao's heart. The two, who were never supposed to cross paths, begin a passionate affair, drenched in sweat, triggered by this inadvertent witnessing of her self-pleasure.
