My mom was a hooker

My father fucked off and to support her 2 children, our mother started selling herself. She worked a low paid job and sold herself to make extra money. My sister got into university and then got a good job. As the youngest and dumber than my sister I trained as a plumber, still a virgin at 22 and nervous around girls. I decided to lose my virginity by hiring a hooker. Also, not knowledgeable about hookers I asked my mother what I should do. She knew my nervousness around girls and told what I had to do. But when asked who I should approach she said she didn't trust any of them, especially whether or not they clean and not infected. Saying they do drugs and don't take many if any precautions, I was then left wondering how I would ever lose my virginity. My mother then said she would teach me and at least I won't catch anything. I was a little shocked, but also relieved, she was someone I could relax with. It also was just before the lockdown for pandemic came into force. We were living together and as we couldn't go anywhere, and she started teaching how to fuck and to please her. Something she said men don't do much if at all and by the time the lockdown ended. I was well trained by my 54-year-old mother. I've gained more confidence and married a girl I met early last year last May. Her family are better off than mine and as a wedding present they gave a 3-bed house. My mother still works her low paid job but has retired from selling herself. My wife is a nurse and works shifts and so I still fuck my mother when my wife is working for old time's sake. But my wife knows I'm fucking her as she is bi-sexual, and we have regular threesomes also. My wife's mother 61 is also a regular, as her father 69 isn't doing much in the bedroom anymore.
