Complete surprise

I'm very well off and not good at relationships but get on with everybody fairly well except in personal relationships. One Friday late in the afternoon a woman 38 who worked at the same business (where I'm a partner) approached me. asking to talk to me about something personal. I'd nothing on and so I stayed later than usual to hear her problem. Her problem she was a widow and had a son who was going to go to university next year and he had just missed out on a scholarship. The courses he was to take were the very expensive ones and would saddle him with a large debt. So, she saw me as way to help her son, as I was in no relationships and liked children as I always played with children who came to the offices. She offered to carry a child for me so I could have a child of my own. I was shocked at first, but I was also interested in the offer, so I made a meeting time with her next day to work out the conditions in a more private place. It also gave me time to look into the legal requirements first. The Saturday afternoon she arrived and I at first asked what exactly she wanted out of the arrangement, she wanted some ongoing contact with any child from the arrangement and financial support of her son going thru university. Nothing too extensive in my view and I was quite willing to agree, but how to produce the child was next to be sorted out. IVF was my first thought, but many legal hurdles for unmarried people exist in our state. Travelling interstate would be very disruptive to both our lifestyles as it could take quite some time to get her pregnant. After we discussed she offered straight sex as the easier option, I agreed and over the next week I'd a legal agreement drawn up. The following weekend we started sexual intercourse and continued until she got pregnant about 2months later. Her son started at university the week before her doctor confirmed her to be pregnant. Sex stopped at first because the agreement first objective was completed, but she continued to see me, and we were getting on very well. So, we started having sex again, no extra requirements on either of us. By the time all health checks were completed we were very close and were in a full relationship. I'd started thinking of actually marrying her and a month before our daughter was to be born asked her to marry me and she accepted, and we married 3 weeks after the birth of our daughter. She was my personal assistant from the start of our arrangement and still is today, at first it was to help with us getting together for the sex and then having her close during the pregnancy. Being married didn't change that and allows her the freedom to come and go as required for our family, which is now four. I adopted her son after our wedding, and she has given me 2 daughters and a son. No more children as she is passed having any more children and her son is finished university and is soon to marry. Most perfect deal I've ever been involved in.
