I am waiting for your step-sister to come out of your bathroom so we can go to the movies. She is taking forever and I really have to pee. I run and knock on the door. There is no answer and it is unlocked. I see she's not inside, you lied. You just have a pee fetish and wanted me to pee my jeans. I did. So you jerk off and cum on my piss soaked jeans.
