Il vizio infinito (1983)

The scene opens with a bald guy in his 30s and a slim brunette in her 20s going at it in a dark, run-down room. They start off kissing hard near broken glass and metal beams — looks like some abandoned warehouse with natural light slicing through dirty windows. She drops to her knees early, taking his dick deep with slow, deliberate strokes, face all serious like she’s working on a fucking project. The lighting stays low the whole time, warm and shadowy, close-ups focused on her mouth stretched around his shaft, his hand gripping the back of her head. Later there’s a quick shot of him jerking off in total darkness, just the outline of his arm moving, then back to her swallowing him down again. You can see the piercings on his dick when he pulls out, shiny in the dim glow from a curtained window. No fuss, no talking — just straight-up oral fixation with a raw, almost voyeuristic feel.
