My sister Marilyn second update

My sister Marilyn moved with me after losing her job and we started a sexual relationship and she got pregnant and had our son Richard after our father. Our mother Gloria is very happy with her first grandchild. Marilyn told she wants more children and I'm okay with that, but I've put my place on the market and have started looking for a bigger place to raise my family. Marilyn is a lot happier now than when she first moved. Only the family knows about relationship and they ain't telling nobody.
