Creaming my Cousin Married again

In the first part of my story, I recently divorced and back in the market as the say. I'd met my cousin Nancy and joking made an offer to father a child for her. After almost 2 months she turned up at my place wanting me to her pregnant. Short version I did, then offered to repeat if she so wished. I moved into her apartment building and my plan was to visit Nancy regularly for sex. My ex-wife Hazel transferred into the area and got an apartment same floor as Nancy. One benefit for was seeing my children more often and maybe a fuck from my ex for old time's sake. Not much chance I thought, first of all Nancy and Hazel became besties and with Nancy again pregnant. Hazel knew I was the father, mainly because Nancy told her. My sexual stay overs at Nancy's apartment became threesome events as Hazel decided she wanted in as they say. She first asked Nancy, and I found out on my turning up for a sleep over. With the children sleeping in the next room, I went with the flow. Hazel got clucky as Nancy's pregnancy progressed and she asked me to get her pregnant. I agreed and she soon got pregnant and decided to reunite the family and so we remarried and bought a house. All back to when we were first married, except Nancy also lives with us and shares our bed. I still willing to father more if required. But it's up to them not me.
