A biker picks up a hooker from the bar. Once alone with the hooker, the scooter tramp puts 50 bucks on the bed and drops his drawers.
The prostitute gasps because the dude has an 18" dick.
"I'm not putting that fucking monster inside me," she whispers, "I'll suck it, but that's it."
"Forget it," the biker replies, taking back his money. "I can do that myself."
