I was hanging out in my room beginning a new book, How The Web Was Won, when my pretty black step sister walked in to ask for some advice. She wanted help picking out an outfit for her date tonight. I pride myself on being helpful, so I decided to give her the time of day. I asked to see what the options were. She came back with some clothes and I asked her to try them on. She told me to turn around, which I did at first, but I took a peek to see what she was working with. Hot damn, my step sister is banging! I paid her a compliment and she gave me a weird look. I asked to see what shoes she was going to wear, too. I asked her to try them on and she bent over in front of me to put on the strappy black boots. She didn't ask me to turn away this time. I took note of that. She came and sat next to me and started rubbing on my penis. I told her this isn't right, but she insisted.
