The Marilyn Diaries (1990)

The scene starts with a guy and a curvy blonde in an art studio, both dressed, standing near an easel. He’s got short dark hair, average build, she’s got curly blonde hair, big tits, wide hips, wearing a loose smock. They’re talking, then she grabs his hand and puts it on her tit. He starts kissing her neck, hands sliding under her clothes, then they drop to the floor. Clothes come off fast. He eats her out for a solid minute — she’s grinding on his face, moaning, legs shaking. Then she flips him over, climbs on, starts riding him slow, then picks up pace. Camera stays wide most of the time, you see the whole room — paint, canvases, natural light from the window. After a few minutes she gets off, he flips her to doggy, pulls her hair, fucks her hard. Ends with him cumming on her back, smear of paint already there, makes it look messy. No cumshot cleanup, just them laughing, pulling clothes back on.
