Sensuela (1973)

A slim brunette with short brown hair is on her knees sucking a guy’s dick in a dimly lit room. He’s got a stocky build, early 30s, average look, and she’s going deep — you can tell by the way her jaw stretches. They switch to doggy style on the floor, her back arched, taking long strokes while a small white dog sits near the corner, barely reacting. Camera stays wide for most of it, no close-ups on faces, but you get full-body shots showing how thin she is and how defined his legs are. Later there’s a random cut to a guy in a store, then a woman by a lake — looks like deleted scenes or wrong file parts. The main scene’s solid if you like minimalist lighting and no small talk.
