I am secretly in love with my wife's sister. She is thirty-nine years old, but looks at least ten years younger. Her long brown hair is silky smooth and gorgeous, and her body is simply amazing. She has the most perfect round butt and small, beautiful breasts. I once got a glimpse of her naked when we were vacationing together, and I think about that image every day. I'm so shy around her I hardly say a word, but she is constantly in my thoughts. I would give just about anything to have sex with her. She is truly the love of my life.
