Il sesso degli angeli (1968)

Starts with a tight shot of a slim blonde with a loose bun lying on her stomach, ass up, underwear pulled halfway down—classic tease. Then it cuts to the main event: four chicks (brunette, blonde, redhead, and a dark-haired girl) and one ripped guy on an inflatable raft in the middle of a lake. They’re all in skimpy bikinis, making out and grinding before the guy starts fucking the redhead doggy style while she’s still on the raft. The water’s splashing, the girls are taking turns riding him, and the camera gets right in there for close-ups of the dick sliding in and out. One of the brunettes has a tattoo on her arm—small but noticeable—and she’s the one who ends up sucking him off while the others watch. The lighting’s perfect, all bright and natural, so you see every detail. The guy’s got a solid build, and the girls are all different body types—petite, athletic, slim—so there’s variety. No boring angles here; it’s all wide shots of the whole group and tight close-ups of the action.
