A couple is in financial trouble.
Yada yada yada, they decide that she is going to prostitute herself in the highway, and he says "You don't make any desitions, any questions he asks, you excuse yourself and you come ask me about it,".
So, she dresses whorish and shows some legs in the highway side. A trucker stops by, and asks "How much for a fuck?" She says "Excuse me for a moment", and goes to her husband.
"He wants to know how much for a fuck"
"50 bucks"
She goes back, and tells the trucker "50 bucks". The trucker says "I can't afford that, I only have 20" "ok, excuse me a minute", and she goes to the husband again.
"He says he only has 20."
"Ok, for 20 bucks, you can give him a blowjob."
"Ok"
She goes back to the trucker and says "For 20 bucks, I can give you a blowjob" The trucker agrees, and drops his pants to reveal a huge cock.
"Excuse me a minute" says the wife, and goes back to her husband.
"Honey"
"What now?"
"Do you have 30 bucks you can lend to the trucker?"
