My Sister Marilyn update

Marilyn had lost her job after the company closed and was broke and moved in with me. After catching me masturbating we started having sex and she missed her periods and got tested. Testing positive to being pregnant and having every test there was and all showed the baby healthy. We still live together and await his arrival, our mother Gloria isn't that happy that her first grandchild is from incest. But our father always the calmer one, just shrugged his shoulders and said they are happy and the baby is healthy and that all that really matters, it far too late now to change anything.
