A guy takes a blonde out on a date. They end up parked at a Lover's Point, where they start making out. After things start getting good, the guy thinks he might get lucky, so he asks her, "Do you want to go in the back seat?"
"No!" she answers.
"Okay," he thinks, "maybe she's not ready yet."
Now he has her blouse and skirt off, the windows are steamed, and things are getting really hot, so he asks again, "Do you want to go in the back seat?"
"No!" she answers again.
Now he has her bra off, they're both very sweaty, and she even has his pants unzipped.
"Okay," he thinks, "she has to want to now." "Do you want to go in the back seat?" he asks again.
"No!" she answers yet again.
Frustrated, he demands, "Well, why not?"
She says, "Because I want to stay up here with you!"
