The "Carreteiro" finds solace in the back of his truck, his huge, veiny cock throbbing in his hand. He rubs himself with abandon, the truck's motion mimicking a fuck. The dim light casts dramatic shadows, accentuating his muscular form. His grunts echo in the enclosed space as he nears climax. With a final, guttural moan, he unleashes a torrent of cum, the warm fluid dripping down his hand, a secret shared only between him and the open road.
