Nasty Girls 2 (1990)

Blonde with long hair and painted nails starts off giving head on the grass, real relaxed, sunlit outdoor scene. You see her bobbing slow, then picking up pace while the guy lies back on a lawn. They move inside — dim room, bed or sofa — she’s riding him reverse cowgirl, grinding hard, then he flips her onto her back for missionary. Meanwhile, the second girl, black, thick with short curly dark hair, wearing a pink bikini, takes over outside. She’s lying on a cushioned patio, guy pounding her in doggy, her ass jiggling with each thrust. Camera stays close during oral, catches every lip and tongue move. Wide shots show the whole backyard setup — palm trees, paved area, natural light. No weird cuts, just straight-up nasty fucking both indoors and out.
