My Sister Sarah

Sarah seemed to be enjoying the show just as much as I was. I stood there watching her peeking through at Katie. I started checking out Sarah's ass. I hadn't really noticed before but her ass was mighty fine. Sarah looked back at me and caught me checking it out. She smiled at me and peeked back through the hole. As she continued watching Katie, she seemed to bend over slightly, sticking her ass out even more. My eyes returned to her ass again wondering if she was doing it on purpose. She looked back at me giggling. What, I said. Nothing, she giggled again.
