Blood Sisters (1987)

One of the girls has long dark hair and glasses, creeping down a dim hallway like she’s up to no good. The other’s a wild-haired blonde in a plaid shirt, clutching a basket like she’s pretending to clean. They meet in a shadowy room and go straight for each other’s pants—no foreplay, just hands diving into panties and mouths sucking fingers hard. The oral is messy and close-up, lots of licking, sucking, and one girl grinding her clit against her partner’s thigh. You see flushed skin, fingers deep inside, and a lot of heavy breathing. The camera stays tight, almost voyeuristic, like you’re watching from the closet.
