A few months ago I moved out from my mother's place to my own apartment and my sister didn't liked the idea. We've been fucking since she was 19, and very often I may say, some times four or five times a day when we knew we would be all day alone at home. I told her she could visit it me and even even stay for the night when she had time. What I didn't tell her was that I have a girlfriend that's 1500 km away, finishing college and that in 3 months we're planning to live together and see how it will go.
