Trading up update

I divorced the arsehole I had married and moved back to my hometown, with only my younger brother David now living there. I moved in with him and went him on a trip to an old cabin he had bought. It had no electricity and running water and a outside toilet, during the night sleeping in the same bed we had sex and have continued fucking ever since. I was on the pill and after a while started thinking of having children. So I stopped taking the pill and have now gotten pregnant, David was shocked at first I got pregnant, but is also delighted at becoming a father. Who every test possible showing the baby girl is healthy. We live as man and wife and David has gotten another linesman job closer to our parents and we are in the process of moving. With sale of David's house completed and having bought a new house nearer our parents. Who aren't as shocked by our relationship as I thought they would be.
