Planned Parenthood

I was 23 when I was asked by my second cousin 36 to get her pregnant. She's a career woman and wanted a child, but decided to keep it inhouse you could say. I was a little shocked at first but decide why not. Everything went as she wanted; we had regular sex till she got pregnant. Testing done to make sure everything was okay with the child, one thing she didn't expect was to have twins, but double the fun I said. I resumed fucking by mutual consent during her pregnancy and after the birth of our twins she got her tubes tied. Sex was still a part of our relationship after the operation, now 6 years later I'm myself am married with 2 children and live with my cousin. My wife is her secretary and regularly has threesomes with me and my cousin.
