Peeking through the open door of your step-sisters room you find me changing clothes. You can’t help but watch me but I catch you peeping! I cover up at first but then I start to tease you, you like watching your step sister change? You perv! You try to deny it at first but it’s too late, I know you want me. After all you’re still watching, so why don’t you come in and keep watching. I want to watch you stroke your cock while you look at me. Such a perv… After I’ve stripped for you, I wiggle my ass around, and let you see every angle of my naked body, telling you to stroke faster- don’t stop! I know you like this, you’re so hot for your step sister. After watching your reactions for a few minutes I can tell that you like my ass best. I spread my ass cheeks for you, and tell you I want you to cum for me step-bro, I want you to cum all over my ass! After you happily oblige I tell you I knew that I could make you cum, and if you ever want me to make you cum again all you need to do is ask!
