Inherited

I'm Jacob 47, 2 grown children who have their own lives now and don't visit me very often. My ex wife has remarried and is happy as far as I know and I was getting along quietly with my life. Then a uncle died, I had heard of him never met the man. Uncle David was a bit weird I had been told by my late mother his sister. But I was told I was the only one left in his will, he had no children of his own. I inherited 701 acres of land and several businesses as well and as well stocks, bonds and cash. The land wasn't in one great lump, but spread out in 3 states. As luck would've it my own business had received an offer to buy it out and so I accepted and sold my apartment as well and move to David's home. I told my children of their great uncles passing and I had inherited his estate, but not what it contained. They were all that interested as they had also heard him being called weird. I arrive June 2021 and found a 5 bedroom 2 bathroom modern house and it sat in 33 acres of land with a large shed at the back of the house and a heated swimming pool inside it no other buildings on the property.
I started checking out the businesses and sold off each in turn, I wasn't interested in running any of them. I'm not great on housework or cooking and decided to get a housekeeper and advertised for someone, several applicants and I finally selected Elizabeth 57 slender good looking and looked efficient and she came with her daughter Wendy 36 and I was happy to have both working for me. I was still sorting out the estate at the time and hadn't thought much passed that. But with the sale of all the excess property and the businesses completed, I was ready to start my new life. It was then that I started looking for sex and nothing took my fancy locally, the women who I was interested in were already married or in a relationship. I hadn't thought of Elizabeth or Wendy at that time as possible lovers. With Christmas approaching and my children not visiting, I would be alone except for Elizabeth and Wendy. I walked to the large shed on Sunday nothing planned and Elizabeth and Wendy were swimming as it was their day off and they were allowed to use the pool. Which they did on their days off, it stuck me how great they looked in their swimsuits. I hadn't taken much notice before and it was my time seeing them swimming. Anyway I decided to see if I could start a relationship with or the other. As it turned out Elizabeth was quite willing to share my bed for in her words mutual satisfaction, Wendy wasn't keen on having sex without a relationship. So I started dating Wendy and finally fucking her, while regularly fucking Elizabeth as well. I June I decided and asked Wendy to marry me and she accepted. My Children finally made a visit to attend the wedding last week and quite like Wendy and also like Elizabeth. Only changes in our relationship is Wendy is my wife and Elizabeth is my mother in law and no longer employed as housekeeper. She gets an allowance and still does the work as before the wedding and Wendy helps her and is trying to start a family. We all sleep together and sex between us continues as it had since we started fucking.
