Bratty Sis Simon Kitty has been my stepsister for as long as I can remember, and she's always been the bossy one in our family. She's always been the one to decide what we do and where we go, and lately she's been pushing me around even more than usual. But last night she did something that I never expected—she finally let me get it to a sex act. Despite her dominating nature, she was surprisingly open-minded about it and even encouraged me to take the lead. We ended up having a great time, and I'm so glad that she finally let me get it on with her. I'm sure that this won't be the last time that we do something like this, and I'm looking forward to exploring our sexual relationship further.
