Old neighbor

I (39) live in an apartment building on the third floor, my closest neighbor is 57 widowed and I'd never seen her smiling. Not that I had much to do with her, she was always annoyed at something or another. I'd move there after my divorce and wasn't socializing at all; my ex-wife and children didn't want anything to do with me. Which suited me, as my wife had the money in our marriage and the children like her more than. So, no alimony or child support and I'd a great career to fund my lifestyle boring as it was at the time. The old neighbor was in the elevator with me one day on our way to our floor. Not a word passed between us, she went into her apartment me into mine. That was the closest we'd been since I'd moved in. Anyway, the following day Saturday I'd nothing planned, and it was a holiday weekend. Most of the tenants were away or out visiting or something else. It was just me and the old neighbor left in the building, then I got a knock on my door. It was my neighbor; her sink was blocked, and the janitor wasn't answering. She wanted me to unblock her sink, I hadn't anything else to do and was bored so I agreed to have a look. She hadn't said a dishcloth had gone down the disposal and become stuck blocking everything. So, I'd to get under the sink and take everything apart to remove the dishcloth. While I was under sink, she was standing very close, and I could see under her dress. She wasn't bad looking for her age, I'm not backward myself and asked her if she wanted to have some fun. At first, she said No, but as I cleaned up, she thought it over and for whatever reason changed her mind. I spent the rest of Saturday fucking her and had dinner with that night. I got home after 8pm and was really drained. In the morning, she went to church and later I saw her as she returned and joined her in the elevator. She had smile on her face on seeing me, I took it as a positive sign she might want repeat. So, I asked her, she said she very sore from Saturday's fun. But didn't say no and so I suggested she join me in my bathtub, and I would ease her soreness. Still no refusal or any answer for that matter, I decided to leave it at that and try again another day. But she came to my apartment with me, instead of going to her apartment I took that as a yes and again I got to fuck her, and she stayed the night as well. I found out she had been badly treated by her ex-husband and had low view of men. I hadn't treated her badly and had asked her for sex, not demanded it. Also, I wasn't rough with her and seemed to care about her enjoyment not just mine. That was October 2023, and we still have sex regularly on a mutual satisfaction basis. I've started dating again and use my neighbor as a backup, me dating isn't a problem for her, so she says.
