Malombra (1984)

Starts with a skinny Asian chick in a sheer black robe, barely tied, standing in a dim bedroom. You can see everything underneath, but she’s not full-on naked yet — just playing with the tease. Then this white dude with stubble grips a metal bed frame like he’s about to lose it, shirt still on, looking all tense. The real action kicks in with a redhead on a dark bed, riding a guy in cowgirl. The lighting’s so low you mostly see shadows, but you can tell she’s going hard, hair flying everywhere. There’s also this weird vintage part outside where a guy in a vest holds flowers with a girl in gloves — no sex, just flirty. The camera work’s solid, especially the close-ups on the redhead’s face when she’s getting off.
