Double Exposure (1982)

A slim brunette with long dark hair is on her knees sucking a thick cock in a dimly lit bedroom, deepthroating with her head bobbing fast. The guy, muscular with short dark hair, takes over and fucks her hard in missionary — you see her face strain with each thrust. They switch to doggy, her ass flexing as he pounds her from behind, one hand gripping her hip. She jerks him off afterward, close-up on the cumshot hitting her tits and face. Camera stays tight during the action, lots of focus on facial expressions and penetration. The whole thing feels raw, no breaks, just straight fucking from blowjob to creampie.
