Who says the wife's mom is a pain in the ass?
I got married four years ago to a woman who is 15 years younger than me. It is the second time for both of us. Her mom is only a couple of years older than I am and due to this we get along very well. She is divorced, average looking and slightly on the heavier side.
A few months into our marriage, I ended up in her town and instead of staying at a hotel, my wife suggested I stay at her place. Her mom was most pleased with this and told me she was eagerly awaiting my arrival.
After completing my work, I arrived at her place quite late. We had dinner and sat down chatting while having some wine. After a few drinks we felt quite light headed and the conversation started becoming raunchier. She started asking me about her daughter and married life, and soon the topic moved to sex.
She asked me whether I felt inadequate to satisfy a much younger woman and that if I was ever concerned that her daughter would seek sex outside our marriage after a few years. I replied that it was actually the other way round and my sex drive was even at this age much stronger than her daughter's. In fact I told her that I still masturbate twice a day when we do not have sex.
My mom-in-law perked up; "Oh really?" she said and added that I should have been with an older woman like her, who could pace with me. I laughed it off, but she seemed to take it as a challenge. Soon she started kissing me and rubbing her 34D breasts on my face. Her hand then moved down my shorts and started stroking me. With the other hand, she alternated between rubbing the underside of my balls and fingering my asshole. I could not take it much longer and soon started spurting.
"Now your turn to make me cum"she said and parted her legs exposing her hairy cunt. I needed no further invitation and started licking her clit with my tongue in circles. This was soon followed by finger up her pussy, then two, then three. It was quite big, I guess; my wife could not take more than one finger. Pressing her abdomen with my one hand, I started massaging the inside walls of her pussy, trying to get as close as possible to her G-spot. After some time, she could not control herself and said she wanted desperately to pee. I held her back and told her to just close her eyes and enjoy the sensations. She was glad she did because in a few moments she exploded with one humungous orgasm and fell in my arms shivering.
We mutually masturbated each other two more times that night before I had to leave the next day.
From that day onwards, we have always been very close. We have done this quite a few more times since and she has always said that we could go all the way if I ever found my wife cheating on me. What a woman!!!
