Family Fun

My sister 25 lives with me her only sibling, our father left after my sister was born and we heard nothing about him since. I'm 28 and won the lottery when 25, it helped make our mother's last year a lot better than it otherwise would've been, she passed away due to cancer 18months ago. Since our mother's passing, we stayed together never dating coming to terms with our loss of our mother. Didn't date before her passing either, so it was to be expected we would console each other. Consoling became sexual and as of January my sister is pregnant to me. We've had every test, and nothing found bad yet found. But we're known as brother and sister locally and had gone away for doctor's visits and testing. Own no property locally and have decided to move to the town we see the doctor and the doctor think we're married. We're happy together and decided very quickly on my sister getting pregnant to pretend to be married and live as man and wife. We've bought a house in the town we're moving too; it's also in the next state. No relatives we're on speaking terms with, so we've told none of our moving away. My sister and I really enjoy our sexual relationship, and she wants at least two children. I'm willing to go along with her decision, the more the merrier I've told her.
