That Grandmother Thing

I read on here about a boy making it with his grandmother. This is not uncommon. At the beginning of this summer I started having a more intimate relationship with my grandmother.
I was over at her house one day and the weather was very hot. She joked and said how we could always just take our close off to be more comfortable, mentioning how she of course wouldn’t tell my mom – her daughter. It sounded like fun, and under the circumstances we had no problem in having sex.
I thought that it was great getting to do this with her, and she thought t was great getting to do it with me. It was fun and quite a turn on, and very meaningful doing that together.
My grandmother asked me if I had ever done this with my mom, and of course I told her, no. My mom would never go for something like that, and my grandmother said that she didn’t think so, either. But for the two of us this is a great arrangement which we have happily continued.
