Horny Mash, the construction worker, finds himself in a deserted site, his lust boiling over. He strips off his sweaty clothes, revealing his throbbing cock. With a firm grip, he begins his punheta, the sound of his hand against his meat echoing in the empty site. His strokes are rough, intense, as he feels the cool breeze against his heated skin. He imagines the crew watching, cheering him on, their own cocks out, ready to join in. His breath hitches as he feels his orgasm approaching, his cock pulsing, and with a final, powerful stroke, he unleashes a torrent of cum, painting the dusty ground with his load.
