Better late than Never

I'm Bernard 61 and 1 child almost 2, after years working and doing very well for myself I decided to retire. I was single never married and so I purchased a 4 bedroom house on 3 acres outside a nice town which everything I thought I would need. I'm use to having servants do things for me around my home. So I hired a housekeeper and her daughter, live in as I had the space and it meant they were there when wanted. Shannon 58 and Katherine 35, they weren't locals and it meant none of their family dropping by. Everything was going great and I would get horny and take care of it by masturbating myself. Shannon caught me this time and to my surprise offered to assist me and I accepted and got me off. Anyway once we had started her masturbating me, we continued doing it that way. Anyway she decided to get her self off and mount my cock and rode me until she drained me. That became the normal way after that, I was enjoying her extra service and she hadn't asked for anything in return. I usually read sex stories to get myself ready for sex with Shannon. I read a story about woman and her daughter who were living with her boyfriend who was close to my age and well off like I was and she got him to get her shy daughter pregnant. She told as he had no children and her daughter was so very shy, it would get him a child and her daughter someone later on to care for her. I thought what a great idea, but didn't ask Shannon her view on my idea. I got checked out by my doctor to make sure I could get a woman pregnant first and not find out later I couldn't. I got good news and so I put the idea to Shannon who was at first, not very sure of it as a great idea. But she said she would think on it, the next time she joined me in my bed, she said she was willing to put it Katherine and see if she was interested in becoming a mother and marrying me. I was prepared to marry first and have children after. With the news that a pandemic was probably going to start, Katherine decide to marry me straight away and make a baby second. We married the week before the lockdown started, having sex with Katherine on our wedding night with Shannon in the same bed as us. Once the lockdown started we were coped up together till it ended, sex was the main activity for the 3 of us during the lockdown. We had pregnancy tests and a faint positive just before lockdown finished and so she saw the doctor and was tested and she was pregnant. We had our son and Katherine doesn't take precautions and we she is getting test again tomorrow by the doctor. We think she pregnant again, Shannon is very happy, neither work for me anymore as they are my family and Shannon still shares my bed with Katherine and me and will as long as she wants too. Katherine said she will keep having children as long as I can make them. We keep to ourselves most of the time and are very happy with our arrangement.
