G-Strings (1984)

The blonde in the group scene is wearing a tight red top and smoking near a bookshelf. She laughs a lot, then disappears with the brunette into a bedroom. The brunette takes off her shirt first, then goes down on the guy already lying in bed — he’s in his 30s, dark hair, light beard, just chilling with his hands behind his head. Blowjob starts slow, then she picks up pace, deep throat action with his hips bucking off the bed. Meanwhile the blonde walks in, pulls off her pants, and starts touching herself on the edge of the bed before joining in. They switch — the brunette gets on her hands and knees, blonde eats her out from behind, tongue going all the way. Then the guy fucks the brunette doggy style, camera close on her ass, her hair tangled and face twisted. After, they do missionary, he’s grinding slow, she’s biting her lip, fingers in her mouth. Kitchen scene earlier shows the brunette alone, lifting her shirt, but nothing happens there. Whole thing feels like a house party turning into a hookup with natural pacing and real-looking reactions.
