In the dimly lit car, a man's hand snakes down to his bulging crotch, freeing his enormous cock from its confines. He grips it tightly, feeling its throbbing pulse, as he begins to stroke. His other hand reaches down, cupping his heavy balls, rolling them gently. The scent of pre-cum fills the air as he picks up speed, his grip tightening, his breath coming in ragged gasps. The car windows fog up, mirroring the heat building inside him, until finally, with a guttural groan, he releases, his cock pulsing streams of hot cum onto his waiting hand.
