45-year-old Kiryuu Shuhou, married for 20 years and suffering from a sexless marriage, abandons all reason and dives into an extraordinary affair. This AV documentary captures her overwhelmed by desire, openly drenched in endless flows of arousal and squirting as she succumbs to her cravings. Shedding her elegant motherly image, she pleads directly to the camera, "Masturbation isn't enough anymore..."—a raw cry of sexual frustration that strikes deep. The film portrays her climaxing intensely, torn between the joy of encountering a man after ten years and the relentless hunger of unfulfilled passion.
