Old friend of family

I went off to university and my parents sold their house and move closer to my sister her family. Their former neighbors of 20 plus years were very good friends all that time. On my finishing university I started in my career and after several years returned to the city I was raised in. I drove by the old family home, well where it had been as a strip mall had replaced all the homes. I settled into my apartment and feeling horny decided on getting a sensual massage, I would normally have been at work. But had a week's transfer leave. So, I found a massage place online and made an appointment, was told only a mature masseuse 57 was available day at the time. Still made the appointment, on arriving I was shown into a room and strip down and laid on the table a woman came in gave me a massage and then told me to roll over. It was then I saw her face and recognized her as my family's former neighbor, she also remembered me. Anyway, she masturbated me and told me she had fallen on hard times. I gave her my card and told her when she was finished to call me, and I would see what I could do to help her. An hour later she called, and I met her for coffee and a talk. She told me her husband had died of the virus in the pandemic and with funeral and medical costs had drained her financially, having lost her job also. Not able to get a good paying job due to her age mostly, had to take whatever she could get. Hence the masseuse 's job, living in a rundown boarding house. Well, I thought I could at least offer her a room in my apartment, it would be better than what she had. She accepted as anything would better than what she already had. As for work I would pay her to keep house for me on top on anything she could get herself. The masseuse's job was a call in job, and it wasn't regular work. She moved in next day and 2 days later still hadn't any work. I asked her to massage me and said I pay you what I paid the massage place. She done massage and I asked could I touch her she said yes and the next week her spot work was patchy on had 3 jobs and I again asked for another massage after I got home from work. This time she totally stripped naked and done the massage and masturbated me as was usual. I was going to shower and asked her to join me, and she did. During the shower I got a hard-on, and she let me fuck her in the shower and slept with me that night. We became regular lover thereafter and even when I got a girlfriend (nurse), she would let me fuck her when my girlfriend was working. After several months she seduced my girlfriend, while I was at work and started a sexual relationship with her. The first night the 3 of us were together at home we'd our first threesome together. Several more months later I married my girlfriend and soon got her pregnant. Our mutual lover sleeps with us still. A perfect arrangement for us all, she is our fulltime housekeeper and only does massages for us and will also watch our soon to be born daughter when where at work.
