The hidden desires of an ordinary-looking wife. This film portrays married women who engage in affairs not out of marital dissatisfaction or financial need, but purely for the thrill and pleasure it brings. Reika, a seductive wife (27), seeks relaxation in the tranquil hinoki bath of a quiet inn. Dreaming of a detached house in central Tokyo, she pursues pleasure driven solely by her own desires, without making her three-years-older husband feel guilty. From her vaginal walls flows thick, cloudy juice as she repeatedly screams and climaxes, gradually losing her rationality and descending into madness.
