Saving my family line

When I started this I was 33 (2010), and the only one left of my family line. Very wealthy, wanting to restore the family line. I decided against just getting married, as to slow and risky. I concluded that having multiple wives would quicken the salvation of the family line. It took nearly two years to find acceptable women to breed with; in all, I had five. Four of which were in their late thirties, and the last one had just turned twenty. Daughter of the eldest of the four, all willing to provide me with children and have a better lifestyle and future as a result. It wasn't having a child and then leaving; they would stay and help raise every child I had. As of last month, I now have fourteen children. Five by the same month; the only one still able to have a baby. The other nine are by the other four women; one had three children, and the others had two each. It has worked very well; all the women are called mother by all the children. The children are happy with the extended family, and all will get an equal share of the family wealth. As long as I'm able to breed, more children will be added; no new mothers are required.
