Hands Off (1987)

Blonde girl stretched out on the bed, wide shot, one hand buried between her legs, the other resting behind her head. She’s wearing a tiny white top, skirt pushed up, legs spread — no panties, just her fingers working her pussy slow and deep. Camera cuts to a brunette with long brown hair, riding a short-haired muscular white guy in the same room, both of them sweaty, her tits bouncing free as she grinds down hard. The lighting stays dim during the sex scenes, close-ups focused on their faces and the way he grips her hips. Later she’s on all fours, taking him from behind while he pulls her hair, rough but not overdone. The switch between solo and partnered scenes feels natural — like she got so turned on watching or thinking about it she had to start touching herself.
