Electric Blue 34 (1990)

Alright, so this starts with two hot blondes in a fake doctor’s office. One’s got long wavy hair, slim but with big tits, and she’s topless in just a black garter belt. The other’s in a white lab coat, playing the ‘doctor’—she’s got shoulder-length blonde hair and a curvy body. They start with some heavy making out, then the doc goes down on the other girl while she’s leaning back on a couch. You get a solid close-up of the oral—slow, deep licks, and the girl on the receiving end is really into it, moaning and spreading her legs wider. Later, the scene switches to a bedroom where the same blonde is jerking off in front of the camera—legs spread, black stockings still on, fingers working her pussy. Then a balding guy in his 30s shows up and goes down on her while she’s lying on the bed. He’s not the best-looking dude, but he knows what he’s doing—good tongue action, and she’s clearly enjoying it. The lighting’s dim but you still see everything, especially the close-ups on the oral parts. If you’re into girl-on-girl with a guy joining later, this one’s got solid action.
