Striptease (1976)

Starts with this hot blonde — slim, toned, long straight hair, and a tattoo right above her ass. She’s kneeling low, back arched, like she’s about to get fucked from behind or maybe just teased. The lighting’s dark but you can see everything, shot from a low angle so you’re right there with her. Then cuts to some older guy with glasses, gray hair, looking like he’s getting his dick sucked through a glass or something — close-up on his face, all focused, no partner in frame. There’s also a brunette with shoulder-length hair in a car with some dude, just talking or setting something up, nothing explicit. The doggy shot of the blonde is the best part — she’s got that tight, tattooed look that’s hard to ignore.
