Doing my sister in law

100% fiction!

My sister in law came to our house for spring break from college. she went to school in Wisconsin and we live in Texas so the weather was much better in March at our house then up north. She had done this a couple of times and each time I wondered what it would be like to fuck her.

One year she hooked up with a friend of mine and for a full week she fucked him every day, two or three times per day. He told me all about it and what sticks is that she just liked to fuck over and over again. As I am sure you can imagine, I wanted this as she is a babe. Every time I see her I think about entering her every where there is an opening.

The last time she came down my friend was out of town and I know she wanted to fuck him. My wife was pregnant with our first child and sex was few and far between with us so I was really horny. I suggested that my sister in law and I go to party some of my co workers were having and my wife was all for it as she had to work and did not want to go to anything. She thought it would be fun for Liza (my sister in law's name) Now I had no intentions at that time so we went to the party and there was plenty of drinking and Liza was having her share.

To describe her, she is 5'3 tight body, brown hair and medium size tits but very firm and tight. She has a great ass and is very pretty so, yes she is a babe.

Towards the end of the night she was sitting on the couch and I was on the floor in front of her, just sitting there. For some reason, and I do not remember why, I put my hand on her knew and turned to her and said, having fun as she said yes and started rubbing my neck.
