From Sodomania with Love (1985)

A slim brunette in her 20s stands in a doorway, hands on hips, wearing nothing, looking like she’s ready to go. The scene cuts to her on her knees in a bedroom, giving a blowjob to a well-built guy with short hair — you can see the movement, her head bobbing, really deep throats him. Later, a blonde in long hair shows up, also slim, playing with her fingers, then gets into some kind of intimate contact — there’s kissing, touching, maybe some girl-on-girl teasing. The lighting stays dim, handheld close-ups focus hard on faces and genitals, especially during the prep shots where the brunette spreads herself. Most of the sex happens on or near the bed, with the brunette taking cock from behind and in close missionary. Camera stays tight, doesn’t pull back much — feels personal, almost voyeuristic.
