Tabu (1977)

Starts in a dim bar with a bunch of people mingling—blonde MILF in a bright orange scarf gets real close to a guy with slicked-back dark hair, lips almost touching. Then the scene cuts to a different room where a skinny brunette with long straight hair drops to her knees and goes to town on the same dude. She’s got a tight grip on his thighs, and the camera’s low, so you see everything from the side. Later, the brunette’s back solo, hands near her mouth like she’s teasing or about to touch herself—lighting’s dark, so it’s all shadows and close-ups. Last part’s outside on a street with a girl in a wheelchair surrounded by military or cop guys in uniform—no sex yet, just setting up for something, but the vibe’s different from the bar stuff.
