James Bande contre O.S.SEX 69 (1986)

Starts with a skinny blonde with huge natural tits leaning forward, ink on her back, ready for doggy. Guy’s got a decent dick, jerking it in a dim room before they head outside. Next thing you know, all three girls—blonde, redhead, brunette—are messing around in a pool with a noodle, no suits, tits bouncing everywhere. Cut to a boat where the brunette’s on her knees sucking him off while the blonde watches, legs spread. Best part’s the beach scene: redhead’s lying on a towel, blonde’s on all fours over her, and the guy’s pounding her from behind, sand flying. Camera’s right in there, close-ups on the dick sliding in and out, ass slapping. Lighting’s solid, no weird shadows, just bright daylight so you see everything. Girls are all slim, young, and into it—no fake moaning, just real panting and dirty talk.
