La Minorenne (1974) (HDTVRip)

The blonde is skinny with long straight hair and a flat stomach — you see her topless early on, standing on a rocky hillside, playing with her small tits in natural light. Later, she’s in a shower with a short-haired brunette guy, muscular build, soapy bodies sliding together under running water. They start with her on her knees, mouth full of his cock, then switch to standing doggy — he’s gripping her hips hard, pelvis slamming into her bare ass. Camera stays wide during most of it, no close-ups cut away, so you get full body motion throughout the fuck. The angle in the shower shows water dripping off her tits as he fucks her from behind, then they face each other for missionary with her legs up against the tile wall. Everything’s well-lit, indoor and outdoor shots look real, no staged lighting.
