Extreme Close-Up (1979) (Better Quality)
Blonde in her 20s with a tattoo on her shoulder goes deep on a guy’s cock, taking it all the way down her throat multiple times. You see everything — her lips stretched, his hand gripping her hair, the slow pull-back with a string of spit connecting. After the blowjob, she lies back and starts touching herself, spreading her legs wide while fingering her pussy. The camera stays tight the whole time, focusing on wetness, clit rubs, and her facial expressions as she gets herself off. Guy shows up later in a wide outdoor shot, but the real action is all bedroom-based and up-close. No dialogue, just raw solo and oral sex with zero distractions.
