Have her sit on my cock

You lift Sarah up off your pulsing cock. She grins at you, dark hair falling across her face. You raise her up and sit her on your lap, facing out the windshield. Sarah grabs the dashboard, and you lift up her skirt, and pull her panties aside. You hold her around her slender waist, and lower her perfect ass down onto your rock-hard, throbbing cock. You're stoned, and forcing your slippery cock into beautiful Sarah's sweet tight asshole. At first it doesn't fit, but you slowly push it in past her clenching anus.

Sarah moans as she sits on your cock, sliding down your shaft, taking your whole length up her tight ass. You lean back and pump her little body onto your cock. Sarah rides your cock up her ass, twisting and turning to fuck herself hard onto you. Passersby look into your car to see what all the screaming is about.

You feel the flood of pussy juice on your balls as Sarah cums hard from riding your ass. You still haven't cum, and your balls are about to burst. You grip Sarah's hips and thrust her down hard onto you, shooting your hot load deep in her guts. She screams and moans, her ass clenching your cock, milking the cum out of you. When you've finally pumped her full of your cum, Sarah leans back on you, panting and breathless.

"That ... was so ... good. I want you in my ass all the time." Sarah sighs and snuggles against you. She sings happily on the drive back to school.
