Life with my Sister Janet

I'm Graham now 34 have 3 children with my sister Janet 30, when I was at university our parents died in bad traffic accident. Leaving and Janet alone together, but well off financially. I would continue my studies and Janet would start hers, we lived together in the family home and neither of us dated. Preferring to keep to ourselves, when I graduated we celebrated together and ended up in bed fucking. Shocked by our actions at first, but soon decided so what we love each other. Janet got pregnant she didn't take precautions because she was still virgin and didn't date anyone. As the tests showed the baby was healthy no problems she decided to have him. We were stilling regularly fucking as she was already pregnant. After the birth of George named after our late father, we kept up our sexual relationship and Janet got pregnant again and also graduated that same year. This time a girl also very healthy and we named Veronica after out late mother. I also got a great job offer and so we moved interstate selling the family home and buying a new home in our new city. Janet are as everyone we met knows is my wife and also my PA which allows her to have the children with her in the office or at the playgroup provided by the firm we work for. Janet still doesn't take precautions of any type and a year after we arrived she got pregnant again with another girl we called Elizabeth after the queen of England as I was referring to her as my little princess and Janet thought it fitting she was called Elizabeth. I've always referred to veronica as my little angel. Janet and me are very happy and will keep building our family.
