My Wife's Best Friend

My wife and I had been married for a few years, always experimenting with sex. We had a very active sex life as compared to most. We loved to please each other, but she had a friend that I could not get out of my mind.

One weekend, we went out dancing and I found myself getting brave flirting with her. She whispered into my ear that she wanted me. How was I going to get her without my wife knowing? The torture was almost too much to bear!
