An offer I couldn't refuse

I'm not the greatest looking man, on a scale of 10 I would make a 3. I'm Markus 34 single great career and prospects except in relationships. Never any good with women, I'm no virgin nor am I shy. I'm short 5'2" and skinny and the only thing I've going for is my intellect and done very well at university and career wise. I was relaxing and Thelma 39 who work s at the same place came asked me to a private conversation after work that day. I agreed, but no idea of what or why she wanted to talk to me about. The last thing on my mind was sex, good looking women like Thelma would never give me a look. I had pay for women ever since I wanted to have sex. After work we got a coffee each and walked thru the nearby park. Thelma was straight to the point, her clock was ticking and she wanted to have a child maybe two. Before it was too late, still none the wiser I asked so what does that have to with me. She said she wanted me to father her child as I'd great intellect and she hoped the child would gain that from me. I was shocked, but responded but I'm not a great looking man. Looks are over rated she said, I was thing it was some sort of prank at my expense. But she show me booklet on I V F and she had been trying to find a donor. But her search stopped when she heard that people didn't always get what they asked for and any sperm was passed off as coming from the desired donors. With me she would know everything and also the child would know who its father was. I said I would think on it and her my answer next day Friday, I was already thinking of agreeing. But decided to way till later the next day to agree, after lunch I told her I was willing to assist her. Good I'll stay with you this weekend and we can start, I was surprised at her quick response. But she came to my home and we had sex several times a day on the weekend and she stayed the whole following week as well. If nothing else I got plenty of sex. As it turned out she got pregnant after that first week of sex. I would've preferred a longer period of trying myself. That was early February 2020 and by the end of March 2020 tests were positive. Also with the pandemic starting to spread, Thelma asked would I mind her moving in with me over the lockdown period. Your most welcome I said, I like her didn't want to be alone with the a pandemic running thru society. The lockdown came and went and Thelma and I became close friends and she stayed with me after the lockdown and is still with me today. One son and another child on the way.
