It's the night before our parents wedding, and there has always been so much sexual tension between the two of us. I catch you looking at me all of the time, don't even try to deny it. This is our very last chance to fuck before we officially become step brother and sister tomorrow. Obviously this has to stay a secret between the two of us, and I know it sounds crazy, but maybe we should just get this out of our systems tonight. Lets fuck before we become siblings ;)
