Naked passenger
How brave is your girlfriend? Is she willing to let you drive around while she strips and stays naked in the passenger seat? If so then you are either a very lucky guy of your GF is a bit daft, after all, she doesn’t know if you are driving her through a slow-moving and very busy part of town (I’d do that, just to watch her squirm! :D) or even worse, getting pulled over by the cops! How embarrassing would that be for her, getting caught by the police while totally naked!
