Sex Machine (1990)

Blonde in her 20s with glasses and a petite frame looks shocked at first, sitting on a couch like she didn’t expect what’s coming. Scene kicks off with a brunette going down on a muscular dude in bed — sloppy blowjob, close-up shots show her gagging a little. He flips her over and starts fucking her from behind, deep strokes, camera catching every thrust from the side. The blonde joins in later, taking his dick in her mouth again before they switch to a three-way on the bed and couch. One girl rides him while the other jerks him off between kisses. Real dirty, no fluff — just solid fucking and oral with natural lighting and wide shots showing all the action.
