Pinku katto: Futoku aishite fukaku aishite (1983)

One of the girls has long dark hair and a small, slim frame — she’s on the receiving end early, spread out on the bed while the other, shorter-haired and slightly more toned, goes down on her with slow, deliberate tongue circles. They switch off, both taking turns eating each other out, the camera staying tight on faces and genital contact without cutting away. There’s a strapon involved later — black, medium-length — used in missionary and then doggy style, both girls fully into the grind, moaning and clutching the sheets. The room’s low-lit with soft lighting, curtains drawn, a single plant in the corner visible during wider shots. Not much talking, just consistent moaning and wet sounds, the kind where you can tell they’re actually turned on. The whole thing feels private, almost voyeuristic, like you’re watching something real go down between two people who know each other well.
