My old Teacher

In my last 2 years at high school, I'd nice looking history teacher then 31 married. I wasn't planning on go to university, I was going to be an electrician. I left school to train as an electrician at 17. At 26 I still worked for the same firm that had trained me and was doing quite well. I'd bought my own home in a few years would own it outright. I dated and done okay I believe but hadn't anyone special. The house across the street sold and my old history teacher 40 moved in with her daughter 12. She was now a widow of 4 years and was starting at new school at the start of term. I drove a work truck which advertised my employer, so when she had power trouble, she came over to ask me to look at her problem. Her circuit board was outdated and needed replacement was the main problem, but I done a quick fix to return her power and told her it would need replacing the sooner the better. The look on her face told me she couldn't afford the expense at the time. I'd like her as my teacher and said I would do it for her, when a circuit board became available. We change out board regularly, upgrading with larger one and the old one were still good to use. I'd upgraded mine using a replaced board and said I wouldn't charge her for doing it. She knew I was old student of hers, because I'd told her as she hadn't recognized me herself. A week later I was replacing a suitable board for her needs and no prior claims on it by anyone at the firm. So, I put in my truck for replacing her board. I also found an old board in the basement which the one I had removed had replaced it was sitting next to furnace. On finishing my boss called me to ask if the old board was reuseable as he had a new shed of his neighbor to add power too. His neighbor was a cheapskate, and I said the old board wasn't suitable and send him a picture of spare board from near the furnace. So, the cheapskate would've to have a brand new one instead. That Saturday I had to work assisting my boss do his neighbors shed, they were members of the same lodge, so it was expected they help each other. But I got paid off the books cash in hand, it cost the neighbor less that way. The next day I changed the teacher power board and was invited to dinner as a thank you. We were friends thereafter and I would help her anytime she needed help. She had me to dinner regularly, then the school break came, and her daughter went to visit her late father's parents. Her mother stayed home as she was working teaching students who were behind to catch up. Alone no daughter to keep her company we were together more often and ended up in bed fucking. No precautions needed as she couldn't have more children, she hasn't told me why. But ever since she is my close friend with benefits. When her daughter visits friends or away for some reason or another we have sex. I'm very happy with our relationship, it's just friendship no chance of us marrying. But I would if she wanted too, but she not interested in marrying again.
