You walk through the front door of the bathroom after a long day of studying and he gives you a dirty look. You can tell I'm not happy to see you. You ask me why I'm masturbating in the bathtub. I mean I just got out of gym class and I wanted to relax. You look at my butt as I walk away and I see you looking at me. I'm yelling at you for looking at my ass and telling you that you're disgusting, you're my step-brother!! Before closing the door I glance at you with a small smile on my face. You take it as a sign that I really don't want to be left alone.
