I overheard you and your friends talking about me the other day. One mentioned how me, your little sister has a huge thick ass. I couldn't help but notice how shy you got! Does that mean you noticed? Well, mom is out for the day so it's just you and me. What would you do if I bended over for you and shook this ass in your face? I know you're my brother but I've always fantasized about this. Stroke your cock to my phat ass in tight biker shorts then admire my pussy and asshole. Work up a big load for me and shoot it all out when I count to 3. I love my brother so much and want to make you happy.
