La Vorace (1980)

The scene starts with a curvy dark-haired woman giving a blowjob on a leather couch — deep throat action, guy looks relaxed but into it. Next scene, same guy’s now inside the blonde on a fur blanket, her tits bouncing as he pounds her from behind in doggy. Camera cuts to a different setup: younger petite blonde on her knees, sucking the same guy in what looks like a living room, close-up on lips and shaft. Then the wild part — a threesome on a bed, both women naked, the brunette on top riding him while the blonde, now wearing a Roman helmet like it’s a joke, waits her turn. The helmet stays on during her turn in doggy, which is weird but kind of hot. Later, a solo shot of a slim dark-haired girl in bright light, face close-up as she sucks — tongue work is clean, makes you notice her lips. Different rooms, dim lighting throughout except that last shot. Guy’s built, not too tall, keeps his cool through all positions. Blonde is bubbly type, energetic, while the brunette’s more aggressive — you can see her nails digging into his chest. No weird cuts or shaky cam — steady shots, good focus on faces and action.
