Best Fuck Ever

I had recently divorced my wife of 12 years and she got our 2 children. We're quite well off and with the child support and the alimony, I could still do whatever I wanted to do. I was out alone and came across my ex-sister-in-law who was also alone. We still got on fairly well, as the divorce wasn't nasty, just we had drifted apart over the 12 years. So, her sister didn't have to avoid me to support her sister. So, we teamed up to enjoy ourselves and enjoy ourselves we did. Ending up in my hotel room fucking our brains out, she was energic, where my ex just laid there. I rated her my best ever fuck, and we started a relationship. Finally, we married with the full support of her sister and after our honeymoon my new wife was confirmed as pregnant. So, I decided to have an extra holiday and my wife wanted her sister and my children to join us. I couldn't see why not, and we all had a really great time. There was just one thing that happened, my wife and I had a threesome with her sister and now she has also tested positive to being pregnant. At first, I was stunned and wondered what to do. My wife was happy as she and her sister could be pregnant together, those a couple of months apart. I bought the house next to my old home my ex had kept and installed a connecting gate. My ex isn't upset about being pregnant to me and said it was unplanned but was now very much welcomed. My ex hasn't been dating since the divorce and has become a regular bed partner with me and her sister. Our parents were a bit shocked and now accept that they are to be grandparents again twice. Sex with my ex has also improved, but we only have threesomes.
