The hum of the engine and the rhythmic sway of the car mirror the motion of her hand, pumping in and out of her aching pussy. Her other hand pinches and twists her nipple, sending electric shocks straight to her core. The thrill of potential discovery heightens her senses, her moans echoing in the closed space. She's a symphony of lust, fucking her own hand, chasing her orgasm under the watchful gaze of an indifferent city.
