I was always attracted to my mother-in-law. She was a successful, professional woman with great looks and a great figure. She was forty-five when I met her. Whenever we would see her, she would greet and say goodbye to me with a tight hug and kiss on the cheek. I always looked forward to these quick moments. As time went on, I became more and more attracted to her. Several years later, I decided to see what would happen if I got a little friendlier. One day, as I was saying goodbye with no one else around, I casually slid my hand down her back onto her nice firm rear-end. She didn't seem to mind. In fact, she seemed to hold me a little longer in her hug. The next trip, as her husband and my family were taking things into the house, she came out to give me the usual hug and peck on the cheek. This time, she planted a quick kiss on my lips and ran her hands slowly down my chest. From that day on, if no one was around, we greeted and said goodbye with a full lip lock with each trip and each kiss becoming more passionate. One day as I was driving in the vicinity of her town, I couldn't resist. Everything told me that this could turn out to be disaster if I continued, but I went ahead and called her. I told her I was driving through her town and just wanted to say hi. She told me that her husband was gone for the day and that I should stop by as she had been thinking about me. I quickly drove there. She greeted me at the door. We were both excited and nervous. She gave me the usual kiss, but then I pulled her back for the most passionate kiss I had ever given. I put both hands on her butt and pulled her into me. I was so hot for her. After several minutes of kissing, she took me by the hand and led me to her bedroom. We began to take each other's clothes off. She made me promise that no one could ever know about this, and it could only happen this one time. I agreed. We jumped into bed. I kissed every inch of her beautiful fifty-five-year-old body. We then had sex. I had fantasized for almost ten years of making love to her, and it finally happened. We made love twice more that day, staying in bed for over two hours. As far as keeping that promise, it didn't last. We continued to make love several times that year whenever we got a chance. The highlight came when she called our house. She and her husband had planned on going to Las Vegas for her business trip. At the last minute, his job got in the way. She asked my wife if she wanted to go for two days to Las Vegas. She couldn't due to work. My wife volunteered that I could probably go as my job is more flexible. My mother-in-law said that would be fine. I acted all unsure and uncomfortable about it. However, I accepted. The day that we left, my wife pulled me into bed and we made love. Then six hours later, I had checked into the Las Vegas hotel and was making love to her mom. We had two solid days of kissing and sex. We spent almost the entire time in bed. That was several years ago, and my mother-in-law is closing in on sixty. I still am so attracted to her, and we make love whenever the opportunity arises.
