Married one got one free

I 30 decided to get a wife by our custom, buying one. I reasoned it was quicker and of less hassle than finding a woman, dating her and then marrying her is she agreed too. Using a marriage broker who quickly found a suitable wife for, she 19 had no dowry and only had her mother 36 left as family. So was on the marriage market to find a husband, as without a dowry arrange marriages didn't happen. She was everything I wanted and as she only had her mother left, she would also become my concern. She would live with us, and I also had sexual rights with her. As the man of the house my needs come first, in everything. After our marriage my wife quickly got pregnant and during the later stages of her pregnancy was advised to stop sexual intercourse. Her mother took over providing me sex, I also got her pregnant. My wife gave me a son and her mother, is also having a son for me. I really enjoy having two wives, I wouldn't change my choice even if I could.
