Tails from the Tower (1993)

A thick blonde girl with long straight hair is jerking off on a barstool, dimly lit, staring into the camera. She’s wearing nothing on top, looks bored at first, then starts sliding her hand up and down with rhythm. Another girl, a brunette with curly hair, shows up and gets on her knees — sloppy blowjob, lots of spit, both of them making messy open-mouth sounds. Later there’s a scene where the blonde is riding a guy, some close-up shots of her bouncing in a bright office setup, shirt still off, tits swinging. After that, it switches back to the two girls — the brunette eats the blonde out from behind, classic doggy style, tongue deep, camera locked on the angle. Everything’s shot static, no fancy moves, but the lighting and body types make it work.
