So it has been a couple of months since I have posted about Rebekah and I. In that I shared about her submissive side which includes her egging me on to tell her when I think another girl is hot and what I would do to her given the chance. This gets her hot and we often reenact together the fantasy I just shared with her, with her pretending to be the other girl. It is fun and hot as it gives the illusion of cheating without the actual cheating. The apex of this setup was when we went to her house to spend some time away from college and apparently she did not know we were comming or at least that early. We saw her tanning naked out by the pool while Rebekah and I were upstairs looking out the window. I got hard and Rebekah went to her knees and blew me while I told her everything I would do to her sister. This was all I ever thought would happen in regards to this. As we had never shared with any other girl what we had fantasized about together.
