Your sister knows you've been stealing her dirty panties, and she's documented it. If you don't follow her instructions, she'll tell your helicopter parents, as well as everyone at school. She only wants two things. First, you're going to bed over and take her MASSIVE strap on cock in your ass. She eases it in and fucks you good, telling you how she's going to get every inch of it inside of you today. The second thing she wants? You to stroke your cock and cum while she's stretching out your hole. You're going to cum with her cock in your ass, and that's going to be your punishment.
