Mary Flegus, Mary Flegus (1977)

Mary Flegus is on her back in a dim bedroom, wearing nothing, taking a dick in her mouth with her dark curly hair spread across the pillow. The guy above her has a beard and a slim, muscular build — he’s feeding it to her slow at first, then picking up pace while she keeps her hands down. Another shot shows her on her knees, hand stroking a guy’s cock while he pulls her hair, both fully into it. She switches to jerking him off with one hand, close-up on the skin contact, precum glistening on the tip. Later she’s solo on a couch, blonde hair now, short and casual, sitting relaxed like she’s just chilling after the scene. The whole thing’s shot tight and intimate — you don’t miss a gag reflex or a slick palm slide.
