Helping out an old friend's mother

Growing up my friend and I were inseparable, but it ended suddenly one night. He was walking home from his after-school job and a drunk left the road passed out at the wheel and killed my friend. He was only two weeks from graduating, his parents were shattered. I graduated and went on to college and on graduating got a great job in my chosen career. I hadn't seen my late friend's parent since before I graduated from college. They had moved after that last meeting. A couple of years after starting my career I was promoted and send to a regional office of my employers. Main reason I got the job I was single, married couples didn't stay long so I was sent instead. I liked the town and was happy to work there, mostly older people living there and the schools were neglected mostly due to lack of many students. The few younger people were low paid workers and had no option other than staying. As my employer's business was with older people and their financial investments. Few young people wanted our services and none in my new posting. I ran into the mother 52 of my late friend; she was now widowed and having a hard time making ends meet. She worked several jobs to get by but lost one of her main ones when the employer pasted away at 87. Reduced to the working her other jobs, I decided to give her extra work. I'm a tidy person by habit and had a 3bed house, so I asked her to clean it for me and do my laundry. But it wouldn't replace a 6 day a week job as my 3 days offer was. But she lived in a rundown boarding house, so to ease her burden I offered her one of my spare rooms. Adding her cooking our meals as her way of payment. She knew it was charity, but she accepted out of need. We got on very well as we'd always had before when her son was alive. As you might have realized I'm not a great lady's man. So, I was home almost every evening as I'd no girlfriend to take out and there wasn't much chance of finding one in this town either. She could work her other jobs and still doing any work for me that needed doing. Her jobs changed, one would end, and another replace it. But she had a place she could call home after about a year or so. She walked in on me masturbating and was shocked as I was. But she got over it first and shocked me again by offering to get me off. I accepted her offer and it became a regular occurrence between us. Over more time we started showering together and at the following Christmas became actual lovers. I was content with our arrangement, but she wanted me to find an actual girlfriend. As luck would have it, she got a new job assisting at the school and there was a new teacher there. She was a year younger me single shy with men, my friend's mother thought she would be perfect for me. But how to get us together, her luck was in. The Teacher was boarding at the same old rundown boarding house she stayed at. I'd another spare room and her first act was asking me would I let another woman a close friend of hers stay with us, saying she really needed a safe place. Not saying who or what age she was, I assumed she was about the same age and agreed. Then left for monthly meeting at head office, away for three days I returned late on a Friday night. The teacher had moved in and was in her bed asleep, I went to my bed and was joined my late friend's mother who made sure I was well serviced. I slept late and both women had gone shopping, I left a note saying I was going into the office catch up on work. I got home just before dinner time as my friend's mother liked to dinner at 6 30 and I was quite happy with that. Then I met the teacher for the first time, she was shy but wasn't surprised by my age as she had been told everything about me. In the next few weeks, she relaxed more and more with me. Finally at ease with me, I never tried asking her out as my record of failure didn't impress. But my friend's mother hadn't been idle herself, she had seduced the teacher, and they were in a full relationship. The teacher also knew about my sexual relationship with her now lover. So, on the long weekend we got together for the first time, a threesome a bit of a shock at first. But they too became regular for and the women, I even started thinking of proposing, but fate took a hand. The teacher missed a period and mutual lover suggested we marry. The teacher would lose her job if she got pregnant outside of wedlock, and it was found out by the school board. She wasn't pregnant as her next period came shortly before our quickly planned wedding. Quite happy to be married and still sleeping with both women. Not 6 years later still living with both women and fucking both, have 2 children and another due in 4 months' time. Only real change is my late friend's mother isn't working other jobs anymore she is our fulltime housekeeper/lover. I'm very happy with my life.
