Widow across the street

I live in my family home and I'm buying from my parents, they moved to be closer to my sister and her family after my father got promoted. I'm an electrician and 27 single and not date much at all preferring to pay off my parents. Across the street from me is a mature widow 56 slender great rack and a very quiet woman. Hardly saw her when her late husband was alive and only after his death did, she became more visible. My parents knew the husband well but had little contact with his wife. I have a work truck parked in my driveway, and it was because of it she came to see me. She had power problems and as it was Saturday, I decided to check it out for her. I found a dead lizard in the back of her power board and once removed and a minor clean up everything worked again. I didn't charge her for fixing her problem as it didn't require any replacements. As a thankyou she had me stay for lunch with her. Her house was spotless, and she is a great cook also and we talked a while, and I became her go to guy sort out her troubles. I was happy to help as I got fed as a thank you, a great deal better than my cooking. Over some time, I realized she was very timid shy person and only when in trouble would she seek some help. I liked her cooking and started calling in to check on her and taking her shopping on the weekend. After some months later I would just walk in when I went to place, it had just become normal for me to do that. One Friday I finished work early and on getting home, I decided to do the grocery shopping then instead of the Saturday morning. I walked across the street to tell her and just walked in as was now usual. I caught her in just her underwear as she had been making a new dress and had tried it on and then took it off to finish it. She was shocked at get caught that way, but just stood there, no attempt to cover herself at all. I turned back towards to allow her to dress; I had been a little shocked but had quickly got over it. I also liked what I saw and also a bit aroused but didn't get a hard-on. Once she had a dress on, I told why I came and arranged to take her shopping in half an hour and left. I took her shopping, and, on our return, I went and put my stuff away while did the same and started dinner for us. I showered and went over for dinner with her and helped her clean up afterwards, we talked for a while, and I thought I should leave. She mentioned she would shower and go to bed, I being a bit cheeky asked did she want me to wash her back. She looked puzzled and I was about to say I was just joking, she said if you really want too. I was shocked and at first thought she was being a bit cheeky also. I answered okay lead the way, she turned and headed towards her bathroom. So, I followed waiting for her to say just joking, she didn't and on entering the bathroom she started to undress. So, I did also she got into the shower naked and turned on the water and I joined her. I washed her back, and she washed mine and I started to feel her up while washing her front. She washed my front and came across my hard cock, not shocked about me having a hard-on. I decided to try my luck a bit more and fingered her and with her not resisting, I fucked her in the shower. I stayed the night with her having again in her bed and again in the morning. I found out the next morning, she let me fuck her as I was the only man in her life and her late husband had ingrained in her that she was to fulfill her man's every need. As I'd hard-on she let me fuck her as I was the man in her life. I was shocked on hearing that, but it didn't stop me from fucking again that Saturday night. Sex became regular between us; I would visit her or she me and now almost 2 years later I'm quite happy with our relationship. She has never refused me sex or asked me for sex. She seems very happy with our arrangement; I've told she can refuse if she wants too, and she doesn't seem to want too. I've still no girlfriend, but I'm not looking either. I'm too spoilt by my willing widow.
