Breed by my cousin

I'm 32 single and again pregnant to my second cousin 28, related by his mother being the daughter of my late father sister. I was a late child born when my father was 45 and my mother passed away when I was 24 (cancer). My aunt was the older sibling, and she too has passed away. She had 2 children the youngest a daughter, her brother died on active service before having any children. She married at 23 and her husband was wealthy and 14 years older than his wife and only had the one child. Both had passed away in 2020 (covid), he had lung trouble due being a heavy smoker and she had asthma. They got covid before the vaccines were available and it finished them. As far as family all I know of is my second cousin and likewise for him. Inheriting his father's wealth and being the reclusive type not mixing with people unless he has too. Classed as a nerd at university and the only female he was at ease around being me. With our people so depleted he decided to have children asap, it was then he asked me to be the mother of his children. I was shocked, but I'm work low paid jobs my side of the family weren't wealthy. Not in any relationship at the time and doing it tough, I accepted (late 2021) and quickly got pregnant. Having our first child in August 2022 (son), I live with my cousin as his wife more or less, but we aren't married. He is my only lover and regularly fucks me. Our agreement is for to have as many children as I can and to that end, I got pregnant again in February this year. Neither of us are anything special in looks or build, but my life is a great deal better than it was before. I also enjoy the sex with him.
