It was late one night when I got off of work. I have a girlfriend who has lived with me for two years. Her sister was in town for the weekend and I wasn't aware of it.

When I walk in my house I was suprised to find her sister sitting on my couch in just panties. I have always been attracted to her sister in a weird kind if way.

I couldn't walk away as if I saw nothing at all, so I asked how her night was going. She said she was very horny and that her sister was asleep. I thought about it for a second and told her I would be right back.

When I returned she was butt soft place naked.

I walked up to her and she grabbed my length. She could feel it start to harden and asked me take my cloths off. She unzipped my pants and pulled out my length which was rock hard. She wrapped her lips around my length and started giving me the best play job I have ever had.

I was about to climax when she stopped and looked at me and told me to cum in her mouth. After, she begged me to put my length inside of her. We had wonderful sex for about two hours and both came to a wonderful climax together. We put our clothes back on and I went back to bed like nothing ever happened.

WHAT A WONDERFUL NIGHT.....
