Using My Inheritance

I was a late child born when my mother was 39 and my father 50 and when I was 14 my mother passed from breast cancer. When I was 19 my father remarried to a 44-year-old woman who had a daughter who was 15 at the time. My father only wanted a trophy wife and wasn't active sexually with his new wife after the first year or so of marriage. But I made sure she was satisfied, I wasn't that great at dating, but I'm not backward in using any leverage I have. As my father's health was failing, my stepmother needed to keep me onside, especially as my father hadn't updated his will since their marriage. At 24 I had taken over my father's business as he wasn't able to run it anymore. I was regular fucking my stepmother and had also become sexually interested in my stepsister almost 20 at the time mainly because she was still a virgin. But her mother realized my interest and decided to use to her advantage. Her daughter quite shy by nature as used to get me hooked you could say. My stepmother told me I could fuck daughter only if I married her and as a bonus, I could keep fucking her (stepmother) as well. It was too good to refuse and a quick marriage later I was ready to start fucking my wife only to be stopped by my father passing away suddenly. It delayed my consummating the marriage a few days as it was hectic with all the funeral and legal arrangements that had to be made. Another part of the deal was no precautions to be taken by my wife or me. Her mother wanted to ensure a grandchild as soon as possible. I did get my wife pregnant fairly quickly after only 6 weeks, but I wasn't concerned as I was getting sex from both anytime, I wanted sex. Either one or the other or both at the same time. Now 12 years later I've 5 children and am still happy with my choice to marry and taken my wife's virginity. Her mother is still a regular fuck for me also, especially when my wife is in her last term of the pregnancy. No precautions are taken still, and I do have a personal assistant 49 divorced who I also fuck, and she also lives with us as she is my wife's aunt. Sadly, she didn't have daughter to add to my harem only a son who lives aboard. I like to keep my harem all related.
