Midnight Desires (1976)

Starts with a petite blonde outside, lips wrapped tight around a cock in the shadows. Later, two skinny white girls with small tits grind against each other on a bed, legs locked, faces buried in each other’s necks. The camera stays low and close, so you see every detail of the scissoring. There’s also a shot of two guys shirtless, bearded, making out in a dark room — no idea if they join in later, but the girl-on-girl part is the highlight. The lighting’s warm, almost moody, and the angles make it feel like you’re right there.
