My Sister and I

I'm the older sister by 3 years and both of us didn't do well at school so left early to work and help out our mother. Our father died when I was 13 and we were struggling then and more afterwards. Our mother passed away in 2019 heart attack, leaving just me and my sister and we kept to ourselves not dating anyone. Men would only want sex from us, we couldn't afford to get pregnant. Especially as men were untrustworthy at the best of times and would leave us to carry the burden of raising a child alone. So, we got a reputation as frigid men hating women. Which suited us as less men tried to pick us up, we worked together at a small factory. One day (2021) we were told to go to the office, we passed the manager on our way there. He told us the owner wanted to see us, we arrived, and an old man was sitting behind the desk. He was straight to the point; he was last of his family line and wanted an heir or more. Heard the stories about us, being undatable, decided we would do. He wanted us to have his children, if we passed the medical checks. If we agreed, we would get one hundred thousand dollars per child and home we would own. We only had to provide him with heir's boy or girl no matter. But would've to sign away all our rights to any children we had for him. I was interested straight away, my sister wanted to know if we could see the children by having limited access to them. He didn't respond straight, just sat there thinking. Finally, he agreed with a slight change, saying we could help him raise our children living with him and them. We would still get the money on delivery of each child, but the house would only be provided when we left his home permanently. My sister agreed as did I, passed all medical checks and moved to his private island to make babies. Just the three of us there only way on or off was by his helicopter. Straight sex was his preferred way to make his heirs, he is a good lover, not the get on cum and get off type most men seem to be. He had been tested and knew he could father children, it took several months for us both to get pregnant. After home test kits providing 3 positive results each, we left for his mansion. We didn't have to any housework as he had house staff for all that. Anytime he travelled we went with him; my sister gave birth first a daughter and me several weeks later also a girl (2022). We could have cash in there and then and departed, but my sister wanted involvement with her daughter, and I was happy to stay also. Early 2024 we started trying again for more children on the island and succeed fairly quickly that time. I was first to get pregnant that time and soon followed by my sister. I'd a son in late November and my sister another girl in early December. We haven't thought of leaving and like our new lifestyle, he is the perfect person for us I now believe. He makes sure we're happy and puts no pressure on us for anything, we also sleep with him regularly for our mutual satisfaction. In private he calls us his PB's, private breeders, otherwise we are his personal assistants/lovers. With four children now it would silly he said not mention we were lovers. We have no plans except continue as we have been, perfectly happy to have more children if he so wants.
