The doc told him that masturbating before sex often helped men last longer during the act. The man decided, "What the hell, Ill try it,"
He spent the rest of the day thinking about where to do it. He couldnt do it in his office. He thought about the restroom, but that was too open. He considered an alley, but figured that was too unsafe. Finally, he realized his solution. On his way home, he pulled his truck over on the side of the highway. He got out and crawled underneath as if he was examining the truck. Satisfied with the privacy, he undid his pants and started to masturbate.
He closed his eyes and thought of his lover. As he grew closer to orgasm, he felt a quick tug at the bottom of his pants. Not wanting to lose his mental fantasy or the orgasm, he kept his eyes shut and replied, "What?"
He heard, "This is the police. Whats going on down there?"
The man replied, "Im checking out the rear axle, its busted."
Came the reply, "Well, you might as well check your brakes too while youre down there because your truck rolled down the hill 5 minutes ago."
