The offer

I'm the youngest of 3 and not married or in any relationship at 27 (2004). My father's older brother likewise had 3 children his eldest had married a nice woman 23 years younger than himself. She was 32 when she asked me to help her, I the only unmarried male relative of her husband. They had been trying and not succeeding to start a family, my cousin it seems was firing blanks. But not the type to admit any failures, so it was useless her asking him to get checked out. She had got herself checked and had passed, my cousin had served in the military and had worked with chemical during his service. The chemical had side effects and one of them caused men to go sterile. But my cousin believed he was perfectly healthy, and nothing could or would get him to get tested. I wasn't even born when he was in the military. My cousin-in-law asked me to get her pregnant and she had thought about it quite a bit. She chose direct insertion as the method of her choice; two reason she told made her chose it over other possible ones. IVF had too much paperwork and also too much chance of my cousin finding out. The other method was the turkey baster, and it had uncertain results. Straight sex was the quickest way she said, as I only had to get on deliver the sperm get off, she said. But first I got tested to make sure it wasn't a family trait; unlikely she said but better be safe than sorry. I passed and we started meeting secretly having a fuck and departing alone. The first couple of times were somewhat awkward, but it passed, and I was able to do the deed as they say. After about 8 or 9 tries she got pregnant and would've a daughter, which made my cousin happy, but he said he wanted a boy. My cousin-in-law asked would I be willing to do it all again, I nodded. I over did it the second time, not the sex, the fertilization she had twins, and one was a boy. No more sex since with her, but I've married (2009) and started my own family and have twin boys from my first attempt starting my own family and a daughter since then. Lucky the males in our family look a lot alike as my son with my cousin-in-law looks like I did at his age.
