Les Enfilées (1979)

A slim brunette Milf with short dark hair and red nails starts off jerking off a well-built white guy in a bathroom, then takes his cock deep in her mouth. She’s on her knees in front of him, head bobbing as he holds the back of her skull — messy, real-looking oral with spit dripping down her chin. They move to the bedroom where she rides him slow, then gets flipped into doggy, taking long hard strokes that make her tits bounce. Two younger white girls show up — both in their early 20s, slim, dark-haired — one joins in with oral while the other watches before hopping on the guy herself. The three women take turns sucking, riding, and getting fucked from behind, ending with a creampie on one of the younger girls’ stomachs. Lighting stays dim throughout, mostly wide bedroom shots with clear views of the action and facial expressions.
