Justine. A Matter of Innocence (1980) (Better Quality)

Justine’s the blonde in this one, slim with surprisingly big tits, and she’s all over this older dude with a mustache and a hat. They start in a car, her straddling him in the back seat, bouncing up and down with the windows fogging. Then it moves to a dim bedroom — she’s on top again, riding him slow at first, then grinding hard against his lap. There’s a moment where she leans back on the bed, legs wide, letting him pull her hips down onto his cock. Camera stays tight, lots of close-ups on her face and tits as she moans, nails digging into his chest. One part shows her on her knees by the bed, giving a rough blowjob, head bobbing fast, spit running down his shaft. You see the mustache dude’s hands gripping her hair, forcing deep throat.
