Science Project Update

My sister Leslie broke my science project, it was an accident and also was the my first attempt and I had already put it aside and done another. I had already handed it in and was intending to dismantle the other one over the weekend. But Leslie had broken it and was very remorseful over the breaking of it. Not ever having anything over her before I played it up a bit. She promised to make it up to me, with our parents both away that weekend. She took me out to dinner and a movie and then we returned home and she took my virginity. After that I couldn't tell her that she hadn't broken my project, she has kept giving me sex since and every time our parents are away. She hasn't yet got a new boyfriend and so I'm getting regular sex from her. I enjoy fucking Leslie and look forward to our parents being away now. Before I always dreaded it because Leslie would have her friends over for a party and they and her would tease me. So as long as she is willing, I'm also willing.
