One day, I'm visiting my friend Lizzie. We're just sitting around watching TV when her cute younger Step-Sister, Abby, walks by. I can't help, but notice her perky tits paired so nicely with her perfect ass. Lizzie catches me watching and gives me a playful punch. Calling me a pervert. I shrug and pretend it never happen. Lizzie starts nodding off when Abby comes over and says to me, "When she wakes up, tell her up at my yoga class." I say sure. Abby heads to the laundry room to get her clothes and I quickly and quietly sneak up into Abby's room — hoping to get just a little peek of her changing. For better or worse, I got a lot more than that.
