You’re Driving Me Crazy (1978)

The scene opens with a slim blonde in glasses and a brunette on the bed, both in their early 20s, facing each other close in a bedroom with floral wallpaper. The guy, average build with brown curly hair, stands behind the blonde as she gets on all fours. He pounds her hard in doggy style, slow at first but picking up speed, her ass jiggling with each thrust. She switches to riding him reverse cowgirl, grinding deep while leaning forward on his chest. Later, they flip to missionary — she’s underneath, legs up, taking it deep while staring into his eyes. The brunette joins in, going down on the blonde while the guy keeps thrusting. Camera stays tight during oral moments, especially when the brunette eats her out from behind. Lighting is low, moody, with the floral wall and lamp giving it a cheap motel vibe. All three are quiet, no trash talk, just steady sex with little movement outside the bed. The blonde orgasms visibly — face twists, hands grip the sheets — before the guy pulls out and jacks off on her ass.
