Love Muscle (1971)
A blonde girl with big tits and a tight body starts off riding a black guy in bed, slow and grinding, her hands on his chest. Camera is close, dim lighting, gives it a raw, private feel. She leans back, showing off her tits as he grips her hips. Switches to doggy — he’s pounding her hard, you see the stretch and bounce. Another white guy joins, they do a quick double penetration scene — one in ass, one in pussy — not long but intense. Ends with a cumshot to her face, close-ups of cum dripping down her cheeks. The second guy jerks off standing over her, not much interaction but the cumshot shots are detailed. One guy pees in the laundry room, weird random scene, bright lighting, full wide shot — feels out of place but whatever. The sex is rough, not much foreplay, all action.
