For most of the movie, Grace is in the backseat of a car. But she wants to pee and we make a pit stop at a gas station for something to eat and to fill up the tank. During the trip, Grace undresses, she wants to have an orgasm with her vibrator. She gets a real orgasm with her asshole twitching and wets the seat. Since she drinks a lot of water, she goes to pee once again and she's not shy about it.
