They'll do anything for a ride!

You're driving along, and you're horny. So even though it's against your better judgment to pick up a hitchhiker... well, she isn't just a hitchhiker. She's a sexy young chick, and she's standing on the side of the road wearing practically nothing. So you pull over. She hops in. And before you know it, you're fucking a teen hottie on the roof of your car.
