Then a sound grabbed my attention. Thelower door opened. There was someone else there. I felt a hand runacross my bare chest. A man's voice opened...up."Well, you are a pretty little thing aren't you?"I stood there, silently, not even knowing where to begin. No doubt thiswas all part of Mistress' plan. We had never really discussed men muchrecently but I had told her a long time ago that I had fantasized beforeabout sucking a guy's cock, and she had plenty of times forced me totake her. This excited me but I was getting tired of just looking and masturbating. I wanted to do something.One hot summer day, my mom had gone out with her friends for lunch and shopping. My sister and I decided to go to the pool for a swim. I went in and my sister joined after me. My sister had kind of distanced herself from me ever since puberty. We didn’t have the kiddish wrestling and hugging and rolling after her boobs grew. But that day, we were both in a really playful mood.She started pulling. I asked her why to which she replied by saying that she was tired and that she was at the hospital all night because her brother was sick.She was sitting on my bed. I moved in and started massaging her shoulders, at first she looked at me with shock but did not tell me to stop. After a while she started moaning. I could not control myself, my dick had become as hard as a rock. Luckily my underwear held it in. I massaged her shoulder and starting moving down. I went from massaging her shoulders. The worst one ever I think was one year around Halloween. My parents were gone for the weekend and she was in charge. My mom had gotten her a Cinderella costume. Not the cheap ones either, this one was rented from a real costume shop. She refused to wear it. So she dressed me up in it instead.From head to toe, including the costume jewelry, the long white gloves, the blonde wig and tiara, and the 2-inch heels that I had never worn before. Since it was cold she put the faux fur wrap on me that.
