Living With My Sister

As kids we had to go live with our grandparents after our parents got divorced. There were money issues, fights between our parents, we didn't want to go to my father's, new school, and my sister and I had to share a room. I was fourteen and she was nine and I had to be the big sister.

We live with the same man, we still share a room, she is still my little sister, but we are not kids. We never have synced up our periods, he gets sex all month long. I like sex, a lot. So does my sister. I don't know why, we just do. He benefits, and we get to live with him. I guess it's a fair trade.
