La Orgia (1978) (Better Quality)

Starts with a redhead on her knees sucking dick like she’s starving for it. The camera catches every slurp, and you can see her tits bouncing while she works. Then the blonde and another brunette join in, making out and touching each other while the guys take turns. One of the brunettes has a tight little body but big natural tits—she rides reverse cowgirl and you get a perfect view of her ass slapping against his thighs. The lighting’s dim but warm, so you can still see everything without it feeling like a cheap clip. They pass around a bottle of something strong, laughing and grabbing each other between positions. The guy with the stubble gets double-teamed at one point, one girl sucking while the other grinds on his face. No fancy editing, just raw group action with a mix of skinny and curvy bodies.
