This is something which started this time last year, after an old school friend I saw told me she'd seen my wife claire, kissing and then sucking off a guy at a party she went to.
I knew my wife was a very sexually needy person, but I'd always I thought been good to her in every way, sexually and looking after her in our marriage. I also knew Claires mother Tina fancied me from the word go.
Not letting my anger subside and knowing Claire would be at work the next morning, I called by my mother in laws house. Tina was putting in some washing when I walked into the kitchen. Not wasting anytime on pleasantries I told Tina I was horny, I also told her I knew she'd always fancied me and then said "Lets fuck". It was a pure gamble. If Tina told me to fuckoff I was going to leave her daughter and tell Tina why. As it was I was banging my mother in law ten minutes later after she'd sucked my cock to it's full seven inches. Making her lean over the work top, I had her spread her ass cheeks and then I hammered away at her very wet, but but very tight pussy.
I've been fucking my mother in laws pussy and asshole every chance we get ever since. I've even gone home from fucking Tina and waited for Claire to finish work, and then fucked her without taking a shower. She might be older than Claire, but her mother can more than compete in the slut stakes anytime.
