It goes back to the first time I ever met her in 2002. It was at her friend's lake house to meet my girlfriend's parents and enjoy a boat ride. Of course my girlfriend was running late but not that big of a deal because I knew the parents friends (that's how I was introduced to the daughter.) The MIL was grabbing something out of her car when I rolled up and she introduced herself warmly and showed me in. I'll never forget the first time I saw her. I was 28 and she was 48 years old and absolutely gorgeous. She was wearing a tight black tank top that showed off some C cup tits and just an ever so slight stomach pooch, barely even there. She had long sexy legs that ran up to her ridiculously short daisy dukes that had a hint of each ample ass cheek showing out the bottom. Skinny ankles and knees and nicely subtly muscled calves and thighs... her legs were awesome! When she smiled her face was absolutely stunning. Her blonde flippy bob haircut suited her perfectly. I followed her up the steps to the lake house entrance and couldn't believe what I was looking at. Her ass was swaying side to side with each step and I knew right then that I wanted her more than her 23 year old daughter. I couldn't believe my girlfriend's mom was walking around dressed like that. The shorts were practically underwear! I would find out many years later that they were very active swingers back then and they played a lot with the couple who was hosting us. There is a very high degree of likelihood that she had been fucked by the male of the couple that day.

I found out that day was a rarity. She was the picture of a stay at home housewife. Great cook, kept a clean and well decorated house. Perfect gardens. She normally dressed quite conservative, but occasionally she would surprise me. Like a boat ride in WAY too revealing of a bikini. The two of us ended up in the cabin alone together and she came in for a hug and a kiss (she's always been a kisser) and I slid my hands down to the sides of her ass cheeks. She just smiled at me before she broke away. Or the time I came to drop something off at her house and she was sunbathing on the deck in a thong bikini and no top. She knew I was coming over and very casually covered herself with a towel after standing up. I probably had a view of her moving around completely topless for 10 to 15 seconds from 6 feet away and she acted like it was no big deal. She went to a Halloween party dressed as a prostitute once and we went over to their house to go with them. She wasn't ready to leave and my wife and FIL went ahead without us and I offered to stay back and ride with MIL. When she came out she was wearing a short skirt, slutty heels, a black bra and a see through blouse. She walked into the family room and asked, "Do I look like you would pay to fuck me?" with a huge smile on her face. I told her I would pay anything for the opportunity. She just laughed and said if I weren't married to her daughter, maybe. One time she had gone to the gym and was meeting my FIL for dinner pretty close to our house so she came by to shower. She had been working hard on her figure and I walked into my bedroom hoping to catch her in some state of undress. She had a towel wrapped around her body and when I complimented her figure she opened it up completely with her arms spread wide exposing her completely naked body to me for more than 5 full seconds! She was fantastic! It was shortly after that when I started bluntly telling her how much I wanted her.

Two years after first meeting my MIL I would go on to marry my wife, but from that first moment and ever since I was more attracted to her mother than her. I would say that fully 80 percent of the times I have fucked my wife I have imagined that I am buried inside of her mother. It took many years, but eventually her sluttiness won out and I began an affair with her that lasted years. The sex was the ultimate combination of passion, sneakiness, lust, and perversion. At one point I vividly remember looking this woman in her late 60's in the eyes while my cock slid deep inside her and I told her she was the woman of my dreams. She smiled and said she knew. She is 72 now and out of shape and wrinkled, but I still want her more than my fitness freak of a wife. I love spreading her soft cheeks and licking her delicious asshole while she giggles and squirms until she is begging me to fuck her. I love when we are wrapped up together telling each other that we love one another while I am filling her with my seed. Her sex drive has taken a major hit in the last few years and the guilt is really starting to get to her but no matter what else happens she will always be the most fulfilling relationship of my entire life.

This happened about 12 years ago. I was 40 and wife's aunt was 61. My wife worked in her aunt's shop which was in an old multi tenant building that Aunt owned on a busy street.

Wife's aunt was a reasonably attractive woman but a bit overweight and married and VERY religious and prim and proper. Still, she had a pretty face that beared a strong resemblance to my wife's, but her overall attitude never made me think of her in any sexual way whatsoever. That changed one Thanksgiving when I was at her house and I was charged with carving the turkey. At one point it was just the two of us in the kitchen and I was slicing up the breast and she commented that it was nice looking breast meat. I agreed and she laughed and grabbed her ample breasts by the bottom and lifted them up and bounced them and said in a hushed tone that she had been told the same thing before. I told her I wasn't inclined to disagree and she just stood there holding them from underneath while I stared at them. I looked up at her face and she had a wry little smile and said that I was bad. I told her as bad as she wanted me to be and she giggled and spanked me on the butt and walked away. Nothing else happened that night but I obviously saw her in a different light after that.

Fast forward to after Christmas and I had to help carry all the Christmas decorations from the shop down to the basement. It was just my wife, my wife's aunt and myself. My wife ended up having to run out a delivery pretty early on and when the aunt and I went down to the basement we had to do some reorganizing to put the decorations away. The basement was PACKED with decorations and event stuff so everything had to carried through narrow passages and kind of re stacked. We were moving past each other a lot and it was obvious that she was intentionally rubbing up against me a lot and at one point I just stopped her when she was backed up against an old school desk and held her still. There was no doubt of the fact that I had a raging hard on pressed into her stomach and she just smiled and thanked me for all the help. I told her she was welcome and hugged her and decided to give her a peck on the lips but she met me with an open mouth and we immediately started making out. As we were kissing I undid her bra under her shirt and started playing with her nipples and she was rubbing my cock on the outside of my jeans.

She asked me what I wanted with an old lady like her and I told her that I had wanted her since Thanksgiving. She giggled and said she hadn't forgotten that. I undid her pants and started to push them down and she resisted for a few seconds before she said we had to be quick and pushed them to the ground and sat back on the desk.and spread her legs. I dropped my jeans and she slowly stroked my cock in her soft hand while I ran my finger over her clit and slid it inside her to test her wetness, which she was very much so. Just as I was doing that the chime from the door upstairs went off and we jumped and put ourselves back together real quick before we went back to stacking stuff. I told her I was going upstairs and she whispered to me that I had better keep my mouth shut so I kissed her real quick and said same goes for her.

When I went upstairs it was my wife and she was putting something together for another delivery but there was another driver coming in shortly so we all got to putting stuff away after that.

I never did anything else with her again.
