New Home, New Special Friend

I'm Jeremy 30 was transferred to the other coast(2021), I work for a large tech company and they required me relocate. Which was okay by me and instead of an apartment I got a 3 bedroom house in a quiet area. Not in any relationship at the time, so disruption to non existing love life. I'm not the outgoing type of person, I prefer a quiet life and don't go clubbing. I was quite happy with the house and setup the third bedroom as a home office. I was here a week when I met Louise 28 a quiet person like myself and works at the local library as an assistant librarian. It was my searching for a book that how we met and she was very helpful. I didn't know she was my next door neighbor at the time, she with her widowed Mother Alison 45. I'm not a very observant person, if I'm doing something it has my full focus. Any we had now met and after if we saw each other we would say hello. A month later, I was in my garden reading and Louise said hello from her backyard and introduced me to Alison. We started to talk more often and I started getting invited to dinners with them. I took a week of home working to work on a problem at home instead of the noise of the office, no distractions. That what I thought anyway, I solved the problem by the second afternoon working at home. That evening I had another dinner with Louise and Alison, I mention the quiet of working home had help me solving the problem quickly. Alison asked was I returning to working in the office tomorrow then, I said no I want to flesh out solution a bit more before presenting it. Next morning I saw Louise head off to work and wasn't actually doing anything except having a coffee. Then there was a knock at my back door, it was Alison and she had come over to talk I thought. But Alison said she had a problem and wanted to know if I would help her. Of course I would if I could, what's the problem I said, I'm very horny and need fucking she replied and opening her coat to show me she was naked underneath. I was shocked and also got an instant hard-on, I wasn't a virgin. But was very active sexually with women either. I agreed and we fucked 3 times that day and she became a regular sexual partner for me. I'm nothing special to look at and Alison is good looking and Louise takes after her mother. Alison doesn't work as she has a kidney problem. But it doesn't stop her draining my balls, she was also trying to get me to date Louise. So I asked Louise out and she didn't accept until Alison accepted for her. But Alison had to join us on the date, which I didn't much chance of progressing as Louise was okay to talk. But rather shy as a date, Alison was worried she would pass away and never have grandchildren. Seeing Louise liked me was the main reason she started fucking me to get me to date Louise. The third date still with Alison along was very different to previous two. As Alison had us return to my house and got Louise in bed with me and her. I was able to fuck Louise and Alison. Louise was now my girlfriend/lover and regular stayed over my place with or without Alison. I decided at the end of March to asked Louise to marry me and she agreed. Marrying at the beginning of May. No great hurry, but as their leased expired in the middle of May. It was better to marry and have my wife and mother move in with me. I want to do right as they say, last week Louise test positive to being pregnant. Thus making Alison very happy, Alison shares our bed every night and will watching baby when it born so Louise can still work as she likes her job. Alison sharing our bed allows me to keep my home office, when baby comes. But I will have to add another room later on or just get a shipping container office at the back of the house. as Alison wants more than 1 grandchild.
