Wanting to have a child

I was 52 single and in no relationship and at the top of my profession, too busy to have a relationship and too driven to succeed. Succeed I did and now I realized I had no family of my own and decided to have a family. But not prepared to wait for a perfect woman, I decided to find a woman pay her to have my child. Easier said than done, but I don't give up easily and one day I saw a nice-looking woman working in supermarket. She was in her early thirties and had no wedding ring on her hand. I made some discreet inquires and found out about her. My profession has its contacts and I found out she was single never married, nor in a current relationship and was having a hard time financially. Her father had passed away and she was paying off his debts and for his funeral. Nothing was known about her mother for twenty years or so. So, I had a possible way to get her agree to my request. (Short version) I asked her if she would like to pay off all her debts and get money in the bank as well. She was interested and agreed to discuss my requirements. At first, she was totally shocked by my proposal. But didn't reject me out of hand, finally we made an agreement. I would pay off her debts and provide a secure well-paid job for her and allow access for her to visit the child. In exchange I got full custody of the child. The job was easy I hired her as my assistant and that would give her access and allow me to monitor her. She got tested and wasn't already pregnant and I had decided to fuck her to get pregnant. No outside help was wanted by me, I had also got tested and was fine. So, she started working for me as my personal private assistant, paid by me and not by my firm. I already had a PA and mt new PPA was to have nothing to do with the firm's business. My private life was already secret and me having a PPA didn't seem strange for to them in regards of my personal life. Any way we waited until she was ready to impregnate and started having sex. She never left my side as it were and even attended every meeting, I attended at the firm. After a while she got pregnant and tested showed a healthy child a boy which was my preferred sex. But not stated in the agreement, she had our son just before the pandemic started and was still living with me when the lockdown was imposed. Breast feeding our son and also providing me with sex as the lockdown dragged on. After the lockdown was lifted, she stayed with me as we were comfortable living together and it allowed her as per our agreement to see her son. We still had regular sex, why not it made our relationship closer. Almost 15 months after our son's birth, she got pregnant again. I wasn't shocked as I was regularly fucking her with the aim of getting her pregnant again. No agreement in place for a second child and as we were getting on so well. I asked her to marry me and make our family whole she agreed and quietly married and now have 2 children both boys and trying for another hopefully a girl this time. No prenup and I'm quite happy with how things are.
