Inside Out IV (1992)

A slim brunette with long brown hair is on her back on a bed, spreading for a muscular white guy in his 20s. He’s got short dark hair and a lean build, kneeling between her legs after she finishes blowing him. They start in missionary with slow, deep thrusting — you can see the stretch on her face. Switch to doggy style next, her on all fours near the edge of the bed, him gripping her hips hard. Camera stays tight, lots of close-ups on pussy lips and his balls slapping. The lighting’s low but clear, looks like natural light from a window with curtains. Later there’s a cut to a guy in sunglasses sitting in a living room chair, maybe a different scene or setup. No dialogue, but the sex is straightforward and well-shot.
