Started my Family

Living with my sister and doing quite well career wise, neither of us doing well dating. Then the pandemic struck, I was able to continue working from home my sister lost her job. Which wasn't a problem anyway, but as the lockdown dragged on, we started having sex. At 28 I'd been thinking of finding a wife and starting a family. My sister was the only woman I was getting sex from at the time, and I looked into problems children born of incest got. I was hearted to find out it was more likely generations of incest that caused the major problems. It wasn't unheard of; children being born being born with no problems from first generation incest. So, I asked my sister to have a child for me and showed her what I'd found out. She thought about it and finally agreed to give it a try, we stopped all precautions, and she soon got pregnant. A month after the home test second positive the lockdown ended, she saw a doctor and was confirmed as pregnant. With no close relatives left since our mother's passing in 2018 (car accident) as our father left us when I was 7 and he never kept in contact. But the neighbors knew we were siblings, so I got a transfer in my job (promotion), and we sold up and moved interstate. Bought a new home and my sister wears our mother's rings, and everybody was told she is my wife. She had our son, and he was very healthy. So, she was very willing to try again for a daughter and now over 3 years later. We've 2 children both healthy boys but tried again and as of last week she had her first home test positive. Will test again and then see our doctor afterward another positive test.
