Tenshi no harawata: Nami (1979)

Starts with Nami sitting in a white lab coat, looking like she’s either reading or just chilling—tits barely covered, long black hair parted down the middle. Then the camera cuts to a close-up of her pregnant belly, all round and smooth, with some dude’s hand (wearing medical gloves) pressing and rubbing it. Feels like half medical exam, half something way dirtier. Lighting’s all blue and dim, so you can’t see faces super clear, but you get the vibe—clinical but with a creepy, intimate twist. No full-on sex, but the way they frame the belly and the gloves makes it feel like a fetish thing. If you’re into pregnant chicks or medical kink, this one’s got that slow, teasing build-up.
