Obsession With Mother In-law

I am still trying to sort out what happened two days ago.

My wife and I have been married for 25 years. Four years ago we became "empty nesters". That allowed us to dapple in the swinging life style. It' s not something we do on a weekly basis but more something we done when we are out of town on vacation.

My wife and her mother have very similar features. Dark hair, green eyes, nice figures with the difference being my wife has tits twice the size of her mother. I have always been fond of her but never considered having sex with her. That changed almost five years ago when we went on vacation together. I'll call her mother "J"

We rented a two bedroom condo and three weeks before our vacation friends we had swung with in the past had to back out of meeting use. My wife asked her mother and father if wanted to go. J jump at the invite while my wife's father declined. My Mother In-law is 18 years older then me and my Father In-law is 22 years older then me. Being in his 60's, over weight by 80 or so pounds he doesn't want to do much of anything.

We arrived at the condo on a Friday afternoon. The condo we rented had only one bathroom and it separated the two bedroom with each room having a door leading into it. The city we were in also was home to 3 of my wife's college friends and on Saturday she'd made plans to visit with all her college friends. Of course J and myself declined to go. J said she was going to just relax for the day and I had my favorite college football to watch. J said she was going to catch up on the jet-lag and just rest.

Saturday morning came and I just put on my favorite pair of loose shorts and a t-shirt. J came out in her PJ's and said she may stay in them the entire day. The dressed after breakfast and by 10am was out the door. The college game didn't start until 11am. By that time I had moved the recliner chair and positioned my snacks . About 10 minutes into the first quarter J came out and sat down on the couch just a few feet from where I was sitting to watch the game.

I've got this habit or kink, whatever you can call it ever since I was a "preteen". It has become such a habit, at times I don't even know I'm doing it. Whether it a movie, show or a sports event I will, without even thinking about play with myself. in between snacking and drinking I was constantly playing with my cock and balls, even slipping my hand into my shorts. What I didn't realize was my Mother In-law was watching me more then the game. Sometime before the half J said she was going to go to her room and lay down for a while. As the half ended I got up to use the bathroom. The toilet is position next to the door of my Mother In-laws bedroom. the door from our bedroom was open and as I approached the toilet I noted J's door was opened about 5 to 6 inches. I could also hear soft moans and what I have to describe as "whimpering" come from her room. My first thought was she was dreaming but when I pushed the door open a few more inches I got the shock or thrill of my life.

J was laying on her bed. She had removed her PJ's and had her legs spread as she was slowing fucking herself with a banana which we had bought when we shopped before going to the condo. She was moving the fruit slowly in and out as her other hand was pinching and pulling on her left nipple. I don't know how long I looked in on her but I finally came to my sense and retreated. No I never did use the toilet. I ended up going outside next to the condo. I had plenty of time to contemplate what I had seen and by the time J came back out I had conjured up in my mind she was probably turned on watching me play with my cock and balls. That was only a guess but it changed how I viewed my Mother In-law and started me down a 4 and a half year journey to fuck her. I flashed her every chance I got. I made sure she caught me naked, soft and hard. I got more physical with her, lots of hugs touching, shoulder massages and even moving away from kisses to the cheek and more lips to lips. A few times when I had a few to many beers I made sure to kiss her on the lips and run my tongue over hers. As time went on she became used to it and even started flirting with me. I was now obsessed with having sex with her. It took such a long time because my In-laws lived 3 and a half hours from us and visits were at best once a month. May times, after visiting them I have my wife give me "road-head" and imagine it was her mother. Whenever we spent the night I made sure I was loud while fucking my wife. even making sure the bed banged against the bedroom wall. More then once I come into my Mother In-laws kitchen the following morning and she'd make a comment about the noise and the "fun time" I had enjoyed. My quest had become a "labor of lust".

I reaped my rewards the night of September 25th and the following morning.
