The Devil in Mr. Holmes (1987)

A brunette with wavy long hair and a slim build goes down on a blonde with short hair and visible tattoos in a dimly lit bedroom. The lighting keeps it moody, focusing tight on their faces and hands as they eat each other out, with plenty of close-ups on licking, sucking, and finger play. The brunette is especially aggressive with her mouth, pulling the blonde’s hips forward and burying her face deep between her legs. At one point they switch to missionary-style with the blonde on bottom, legs spread wide, while the camera stays low and steady. There’s a short break where a young blonde guy sits with them in a living room, but he doesn’t join the action. The whole thing feels personal, almost voyeuristic, like you’re watching real people who forgot the camera was on.
