Making Babies

Frustrated single career women, I'm finished university and started work with a large national firm. The staff at the office I was to work in were mainly women all in their late thirties or early forties, some were married, and others divorced, and a couple never ever married. The married and divorced ones had at least one child, the 2 who were classed as single didn't have any children. I'm nothing special in looks or build and didn't do well dating but did date sometimes. I became aware of being watched closely by the 2 single women. The reason they were watching me, I didn't know and thought they were making sure I done my work properly. But they didn't care about my work, they had sized me up as a breeder. I'm of stocky build and 5'8" and as I said Not special in looks, but I was available and didn't tell tails at work. They also lived together, and I'd thought them to in a relationship. They weren't and both wanted a child and living together and no plans to sell up and part ways. They planned to get pregnant and continue on as before, the idea of having the same father for their children also came to be their idea of building a family bond between them. No interest in marriage and not wanting a man around all the time was also their idea of a good family bonding relationship. I was chosen because I kept my mouth closed and so I was approached by both and shocked at first, I agreed. I moved into their apartment building and had the smallest apartment in the building. Which they owned as well as the one they lived in 3 floors up. My apartment was an old shop that was repurposed into an apartment, and it only had a bedroom 10'by10', bathroom with a loungeroom/kitchen. I didn't cook so they had me join them for meals and sex. I didn't pay rent as fucking them was my payment and it took several weeks to get the first one pregnant and 2 months more to get the second pregnant. I was fucking both, every night I stayed over to impregnate them. After they were pregnant, I still had meals with them and got sex sometimes from either or both. The pandemic struck and they had both had their babies by the time the lockdown was lifted, and I was their only visitor during lockdown. I also got anything they required, and I still live rent free in their spare apartment and still get sex from both sometimes together. I've fathered 3 children with them, and they say that's all they want. After each had their first child, one of them wanted another and she had the child in February this year. I'm told the apartment is mine to use as long as I want and I still meals at their place and sex sometimes. But it's getting to be a rare event these days.
