A trucker had been on the road for a couple of weeks and was looking forward to seeing his girlfriend back home and having sex with her. He was nervous about busting a nut too early and remembered reading that masturbating before having sex would help prolong the act. The only problem was that he didn’t have a place to beat his meat, his helper/co-driver was sleeping in the back and there were no truck stops for miles.
Then he had a stroke of genius and stopped the truck at a wayside. He hopped out and went under the truck to make it look like he was doing some repairs. He whipped out his genius, closed his eyes with his girlfriend on his mind and started stroking. After a while the trucker felt someone tug his leg.
He kept his eyes closed to not disturb the feed from the spank bank and asked “What is it?”
“Highway police” someone answered, “sir, what are you doing?”
“The drive shaft was making a weird noise and I decided to check if everything was okay,” the trucker replied nervously.
“It might be a good idea to check the brakes too while you’re at it, seeing as your truck rolled down the road ten minutes ago”, the police said.
