The Dr. is in the shower as Bellla hops into his car....with her high heels on.

She feels up the seat belt and the whole car...

Then after a few mins she realizes that she can do a rev off and not get busted...(maybe by the neighbors but not him).

So she starts up the car, gets all fazed up...and revvs it off until she has an orgasm (quietly) because she'll get busted by someone.....
