Guardami nuda (1972)

Starts with two slim white girls—one blonde, one brunette—making out soft but intense. The blonde’s got a headband and long waves, the brunette’s got an updo. They’re all hands and lips, no rush, just grinding and whispering. Then cuts to a redhead with freckles touching herself in a dark room—close-up on her face, you can see every twitch. Next scene’s a dude with short brown hair fucking a blonde over a boat railing, daylight hitting them both, water in the background. Big group shot after that: three guys, three girls, all white, all young, going at it on the ground with a campfire flickering. One girl’s riding a guy, another’s getting double-teamed, and the third’s jerking off a dude while he eats her out. Last part’s a stage setup with an American flag—one guy standing, two girls on their knees, one sucking, one waiting her turn. Camera’s steady, no shaky crap, so you see everything.
