Delirio caldo (1972)

A slim brunette with long dark hair and red lipstick does most of the work here. She’s in a car at one point, passenger seat, wearing a tight top, legs tucked to the side while the bearded guy drives. Later she’s on a couch or bed, dim light, blanket tossed to the side, sucking his dick slow at first then deeper with her hand jerking what she can’t fit. They switch to missionary on the cushions — you see her face the whole time, mouth open, hair stuck to her lips. Camera stays close, mostly on her, with a few wider shots showing the room. Nothing wild, just steady fucking and solid oral with a focus on her body and expressions.
