The Perfect Position (1975)

Blonde with wild curly hair and a slim build is on her knees first, sucking a guy with brown short hair on a couch in the living room. The lighting’s dim, but the camera gets tight on her face and his shaft — you see every inch going in and out. She swallows it deep, not faking it, throat working hard. After that, he flips her over and starts doggy-fucking her hard on the same couch, her ass jiggling with each thrust. Camera stays wide for full-body shots, then cuts to close-up when he cums — she doesn’t take it in the mouth, wipes some on her cheek. Later she’s alone in a bedroom, jerking herself off, fingers deep, moaning quietly.
