The verified amateur's workshop is a playground of tools and car parts, but today, it's his own body he's eager to work on. With a grunt, he shoves his overalls down, revealing his stiff cock. He spits into his palm, using the lubrication to pump his length, the sound of wet flesh slapping echoing in the empty space. His breath hitches as he nears his climax, the anticipation building like a pressure valve ready to blow.
