My Stepbrother (you) is such a perv. I heard him and friends over talking about my ass and how much they like it. They were talking about how they would love to touch it, be squished by it, to fuck it. Today you shrunk yourself and snuck into my room to get a better look at my ass, except now it's even bigger and better since you're so small. I see you and call you out on your little plan. I call you a weak pathetic small man, I tell you that you are a perv that needs to be punished. I tease you with my giant ass. I sit on top of your tiny body, squishng you, leaving you gasping for air. I rub your tiny body all over my ass cheeks and then when I think you've had enough, I shoved your body face first inside of my asshole, leaving only your legs out. I farted a few times and eventually my asshole sucks you inside. Oops! I guess my ass just ate my stepbro.
