I'm a Rat

I'm a smartass and use to getting away with everything, I always push the boundaries. But I got a great job and do well financially. So, when my older sister got divorced and needed a place to stay. I, being the closer of the family took her in, she had no children to look after. Anyway, she also had to find a new job as she worked with her ex. But she found it hard and one evening she had too many drinks and got drunk. I got home found her drunk and I had been planning to do a bar crawl looking for drunk women to pick up and use. But I didn't need too, as I had my drunk sister, I took full advantage of her drunken state. In the morning I again fucked her and continued to use whenever the mood took me. But I did get her a good job and still she allows me to fuck her every now and then. I love my sister, but the sex is for our mutual satisfaction. We still date and yet to find a partner to settle down with.
