Blake Styles owned the only automotive repair shop in a small town. His honest prices and skilled craftsmanship all but drove his competitors out of business. But even when he had a monopoly, he never overcharged a customer. However Blake had a secret, little did the town know that nothing gave the friendly town mechanic more pleasure than sitting in one of his customer's cars and vigorously cranking his shaft.
The mechanic felt perverse pleasure knowing when one of his big tough customers ran their calloused hands over the steering wheel of their big old trucks, they were incidentally touching traces of Blake's semen. Of course he always gave everything a good scrubbing when he was done, which resulted in everybody in town complimenting him on his "excellent service". Before the curse hit, he would've masturbated in at least a third of the cars in town.
Most of the time he would only engage in his private activities when he needed to keep a car overnight so he could take his time and really enjoy himself. However some days something would come in the shop that really got Blake's engine revved up or a customer would piss him off royally and he'd use his lunch break for a quick pull on the handbrake just to spite them.
Blake's last wank was one of those days
