Smash’d (1976)

The black guy from the campsite scene shows up later in bed with the white nurse — same muscular build, short hair, no shirt for most of it. She’s in that blue nurse uniform at first, then naked on her back with her legs up, taking deep thrusts in missionary. They switch to doggy against the tent wall, her long blonde hair hanging down, bouncing with each push. You see the IV pole still nearby in one shot — kinda weird but kind of hot. The angle when he pulls out and jizzes on her ass is right at eye level, thick white load. Lighting’s dim but clear enough to see everything, no blur, no cuts during the money shots.
