Maneaters (1983)

The blonde girl has wild curly hair and full, jiggly tits that move naturally as she leans over the guy on the couch. She’s wearing nothing and goes straight to work with her hands, stroking him while kneeling between his legs. The guy, dark-haired and mustached, stays flat on his back the whole time, arms relaxed, just watching her. Camera stays wide enough to catch the whole scene — you see the plants around them, the soft light, and how she shifts her weight on her knees. She uses both hands, sometimes tightening her grip, other times rolling his shaft slow. There’s no face shot of him jerking or cumming, but she keeps stroking until the end.
