Mother In Law Helping Out
After our first child was born my mother-in-law came to help out. One day we were sitting on the couch and I thanked her for all her help. She reached over and put her hand on my penis and said that she could help me out as well. I asked if she was joking. She stood up and took off her pants and underwear and said does it look like I'm joking. She then reached down and pulled down my shorts and underwear. My penis was already hard and she climbed up on me and we started having sex as my penis slid inside her. I quickly ejaculated inside her with a loud grunt. I apologized for it ending so quickly. She said don't worry we have time to try it again. Over the next few weeks we had sex in her room, sex in my room, sex in the kitchen, sex on the couch, oral sex, hand jobs in the shower, and even sex once in the grocery store parking lot. She told me that she could have sex with me only when my wife couldn't. It was a good couple of weeks.
We had three more children and after each one she would come visit. We would have sex over the weeks she was there. It got more difficult as the children got older but we figured it out. My youngest is 9 now and we haven't had sex for a long time. I miss having sex with her. Neither my daughter nor my father in law know that we've had sex so many times. The only person who knows is my brother in law who is my wife's sisters husband. We've compared notes about the sex we've had with our mother in law.
