This is my first submission so hope you all like it. This is a true story but have changed names. My name is Bob, I'm 45 and live in big city. I met my wife Kathy when I was 20 and we hit it off very well. Kathy is now 43. We dated for a few years and eventually married. I was a virgin when we married, however, Kathy wasn't. She had many sexual experiences before me so she was sort of my teacher when it came to sex. Our sex life has always been good, but as you get older, kids and work all become a priority. I'm sure you all know what I'm talking about. When I first met Kathy's mom Diana, I was instantly struck by her beauty. At least in my eyes. Diana has curves in all the right places, 42d breasts and a great ass. She isn't tall, but she looks very good. In the beginning I didn't really think much of anything, but as time went on, I started having sexual fantasies and feelings toward Diana. Also, anytime she would greet me should would kiss me right on the lips. Nothing really sexual, but I though it was strange a mother in law would kiss her son in law on the lips. Anyway, I really didn't think much of it. Diana is currently 66.
Kathy's parents were divorced but Diana had remarried. Overtime Diana would be very flirty with me. At least I think she was or maybe it was just my imagination. We've been to various family parties such as weddings, birthdays, etc.... Diana would always ask me to dance with her when a slow dance would come on. During one of the weddings we were at, she was wearing a very nice dress that came up above her knees. Her breasts looked very welcoming in the dress. She took my hand when a slow song came on and we went out on the dance floor. I remember like it was yesterday how great her breasts felt pushing against me. At first we were dancing with both of her hands locked together, but then my cock started to get excited and hard. She must have noticed because she moved her hands around my neck and I held her around her waist as we slow danced. I felt her push her lower body into me which got me even harder. Nothing else came from that, but thats pretty much how things progressed as time went on. I've had many good masturbation sessions thinking about those events.
Fast forward to about 5 years ago. Diana's husband became ill and shortly passed away. She was very depressed about that. I would visit her a few days a week before I went to work to make sure she was doing ok. A couple times I would just take off of work and spend some time with her and I think she appreciated the company. Nothing really happened except for the occasional hug or kiss. But nothing that said she wants to jump my bones. Anyway, as luck would have it, my wife asked me one night if I thought it would be a good idea for her mom to move in with us. She said it didn't make sense for her to live alone when we had plenty of space. Kathy also travels alot for work so she said her mom would be able to help around the house. I told her I thought that would be an excellent idea. So Kathy phoned her mom and at first she was hesitant and said she didn't want to be a pest or interfere with our relationship. Kathy told her that was nonsense and that its a done deal and she is going to move in.
