Mother and Aunt Combo

I'm married and have 2 children another due shortly, I'm well off and always have been. My wife family not so much, I met my wife at university and well we married as I had gotten her pregnant. I was very happy to marry her and bought our house the week after getting married. My wife's father had departed years before to parts unknown and there was only her and her mother's sister. I had for that reason bought a large house to accommodate us all, her mother and aunt had worked hard to pay her way thru university. Their parents were deceased and no close relatives they knew of. Forgoing any personal life themselves, they worked hard to see my wife succeed. She did and got a start in her career albeit pregnant at the time, starting with me in my family's law firm. Being pregnant didn't inhibit her career wise and her mother and aunt ran the house and would take care of my daughter while my wife and I worked, same with the birth of our son 2 years later. They will also take care of our new son when he arrives late next month. I also take care of my mother-in-law and aunt-in-law sexually ever since my wife's first pregnancy. Both are passed having children and in the later stages of my wife's first pregnancy I started fucking her aunt and soon her mother as well. Keeping it in the family as they say, neither seems to want a husband of their own and my wife also joins in the sexual romps. The sex isn't confined to my wife being pregnant, it's an ongoing relationship. Will be until they stop it, there is always someone willing to be fucked by me in our house. My wife doesn't take precautions and will have as many children as she can. Nobody outside of our little family group know of our sexual relationships, it's none of their business.
