it's my life

Little Johnny is delivering newspapers. He knocks on a door, a lady answers, and he says, "Collect... that'll be five dollars."
She says, "I'm a little short on cash, but if you want, I'll give you sex instead."
Johnny says, "All right."
He walks in, she undoes his pants, pulls them down, and there's the biggest dick she's ever seen...
Johnny reaches into his shirt pocket, pulls out a handful of huge washers, and starts sliding them onto his dick.
She says, "You don't have to do that...I can take all of it."
He says, "Not for five bucks you can't."
