I Tvillingernes tegn (1975)

Starts with this hot brunette—long dark hair, slim but with decent tits—grinding on some white guy’s face. She’s got that just-out-of-bed messy look, and the camera gets right up close on her nipples while she leans in for a kiss. They switch to her riding him slow at first, then she picks up speed, bouncing on his dick like she’s enjoying every second. The lighting’s all warm and red, making everything look even hotter. After they finish, they’re just lying there, him holding her close while they watch something off-camera. No crazy positions, but the way she moves and the close-ups make it worth it.
