Dan Oniroku: Bijo nawa jigoku (1983) (FullHDRip)

One of the girls has long black hair and a slim build, clearly the focus in most shots — they tie her up and make her sit at a table while the other two stand over her. The guy’s short-haired, early 20s, shirtless in several frames, standing close during the tied-up scene like he’s in control. Later it moves to a bedroom where the same girl is on the bed, dim lighting, blanket half-covering her as they get into doggy style and close-up grinding. The second woman appears curvier, also in a kimono at one point, hugging the guy on a balcony with a low-angle shot that emphasizes their bodies against the dark background. A lot of the action is slow, intimate, focused on positioning and restraint — not rushed, with medium and close-up shots lingering on facial expressions and hand placement. You see the long-haired girl’s reactions clearly when she’s being handled, passive at first but then more involved once they’re on the bed.
