First Time with my Mother in Law

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.

It took Diana about 4 months to sell her house, however she had moved in with us while the house was on the market. As time went on, my wife was traveling more frequently and the sex was getting less and less. Diana and me started to get very close as we would go out for dinner together, watch tv, go to the movies, etc... We were getting very close to each other without really realizing it. After a while, we would begin sitting or laying together on the couch watching a movie or TV show and in one instance she had got up and looked me in the eyes and thanked me for taking her in. She gave me a kiss on the lips, nothing that said I want to fuck you, but it wasn't your normal mother in law and son in law kiss either. As time moved on we would start to kiss each other more but stopped short of any tongue.

About 3 months or so after she moved in, i was in my bedroom, masturbating and she had accidentally walked in on me as she was putting the laundry away. She was very apologetic and staring walking away, but I told her it was ok and that I should have been more careful about masturbating when I knew she was home. I told her its been a while since me and Kathy have had sex since she travels alot. Diana said she felt the same way as its been a long time for her too. Then as I lay there totally naked she told me that she also masturbates and asked if it would be ok if we did it together. So there I am with my hand on my cock and my mother in law begins to strip. The moment i saw her naked breasts and her pussy I was in total lust. Kathy shaves her pussy, but Diana's was nice well trimmed bush. That totally turned me. She sat in the chair in the room and started playing with her pussy as I stroked my cock. We pretty much both came at the same time. This would be our thing until about a month or so later until something great happened.

We were sitting on the couch watching a love movie and during one of the sex scenes Diana and me started kissing. Our hands were all over each other. We moved into her bedroom and she took off her clothes and took my pants down and started to give me a blow job. I came in her mouth after about 2 minutes as I was so horny for her. I licked her pussy until she also came. We laid there looking at each other and fell asleep in each others arms. During the night we both got up and started kissing. I felt her put her leg over mine and start to grind her pussy against my cock. She took my cock and positioned her pussy right over as she began to sit on my cock. The head of my cock entered the folds of her pussy and for the first time I was fucking, no making love, to my mother in law. Her pussy was so wet and my cock so hard. We fucked for what seemed like an eternity until i exploded in her pussy.

After we were done, she said she loved me and wanted to know if I was ok with it having sex with her. I told her there is no need to ask as I told this has been my fantasy come true. Every time Kathy would travel for work, I would sleep in the same bed with Diana. We've have had sex many times together. She even started to wear thong panties as that has totally turned me on.

One night, while we were in bed together, I hear our door open a then a scream of What the Fuck.......it was my wife.....
