Driving aimlessly, I'm lost in my thoughts and my hand, stroking my growing erection. Suddenly, a busty brunette passenger hops in, her eyes widening at the sight of my throbbing cock. Without a word, she leans over, her warm hand wrapping around my shaft, giving me a tantalizing roadside handjob. Her touch is electric, her rhythm expert, and the thrill of potential passersby sends waves of pleasure coursing through me.
