Caught from Behind V: Blondes and Blacks (1986)

One of the blondes has short, curly hair and pale skin — she’s sitting on the edge of a bed in a dim room, rubbing her pussy through her panties like she’s really getting into it. The camera stays close, no cuts, just her fingers working in slow circles before she pulls her panties to the side and dives in with two fingers. Later, she’s locked in a lazy kiss with another blonde who’s got longer, wavy hair — they’re lying face to face, tongues deep, one hand on each other’s tits, looking like they’ve done this before. Then the guy shows up — dark hair, short buzz cut, muscular build — he’s on the bed in his boxers while one of the girls goes down on him, bobbing her head with her hand wrapped around the base. The angle is tight on her mouth, clear view of his shaft disappearing in and out as she gags once but keeps going. After that, he’s touching both girls at the same time, one hand on a breast, the other sliding up a thigh, all of it shot in soft light with very little movement from the camera — you never leave the room, never see outside again after the first shot.
