She drives, you serve

She goes to your garage and looks at your car.

"Omigod, that's your car? It's not even, like, pink!" She gets the key and sits in the driver's seat, then pushes it back. Amazingly, her legs also grow a little longer and she winks at you. "Climb in, it'll be totally coolalicious"

You scratch you head.

"You know" she pouts her lips "I could just go now." She puts her pink high heel on the gas pedal, and you obediently crawl on the space below

"Of course" Clarissa says "I don't wear panties. You created me to be a super slut after all"
