Savage Lust (1975)

Dude’s got it made in this one. Starts on the beach with a slim blonde on her knees sucking him off while a brunette with medium-length hair rubs his chest. They don’t waste time—next scene he’s banging the brunette doggy style in a dim bedroom, her ass slapping against the mattress. The blonde’s got a tight little body but the brunette’s tits bounce more when he pounds her from behind. Later they take it outside again, this time in the woods where the blonde goes down on him while he stands over her. Lighting’s natural, so you see every detail—no fancy filters, just raw fucking. Guy’s in shape, girls are into it, and the camera gets right in there for the close-ups.
