The extreme play of the wild woman "Kalbi," who seeks sex just by instinct like an animal. The climax of lust that unfolds not only on the bed, but also on the street without worrying about other people's eyes, is truly the most powerful of the series.
Unfortunately the movie Ura honban: Tōsui bideoku~īn is not yet available on HBO Max.
