Her car, her playground, she thinks, as she parks in a discreet spot. Slipping off her panties, she exposes her hungry cunt to the cool air. She climbs into the backseat, lowering herself onto the gearbox, feeling its cold, hard teeth press against her clit. She grinds, she shifts, she fucks, her moans filling the car as she rides the gearbox to a shuddering climax, her juices coating the machine in her naughty, mechanized tryst.
