On a long, winding road trip, a horny couple finds their hands wandering as they drive. The woman, her eyes on the road, subtly slides her hand under her skirt, finding her clit already wet and eager. Her boyfriend, noticing her discreet movements, smirks and starts to stroke his growing erection through his jeans. The car fills with their quiet moans, the hum of the engine, and the occasional beep of a passing truck, all adding to their erotic symphony.
