Got drunk at a wedding

I 30 was alone at my cousin's wedding; I'd flown in for the wedding a week's holiday visiting the extended family. Next morning in my motel room I awoke, and I wasn't alone in the bed. A woman was laying with back to me and was a mature woman. I couldn't remember who she was, then she turned over and I saw it was my mother 54 (widow). I'd fucked my mother, no doubt as we were both naked and she had the remains of sperm around her vagina. But she is passed getting pregnant, she thanked me for making her feel wanted again. I said anytime I'm yours, turns out anytime was straight away. After we showered together and then went to get a meal and back to fuck again. My mother said she would make the most my visit and she was insatiable, every day of my visit after the wedding we had sex. She said there was a shortage of suitable men for her, as the ones she would fuck were married and the others were creepy her words. After returning to my home, I missed the extra regular sex I was getting from mother. So, I enquired about the chances of a transfer and was able to one after 3 months. I bought a house before my return and asked my mother to live with me in it. She slept with me from the first night in my house and is ever willing to fuck. I still dated women my own age and finally found my wife and we married. My wife is bi-sexual and enjoys sex with my mother in either a threesome including me or just the two of them. I've also started fucking my wife's older sister who wanted a baby and not wanted to marry anyone. My mother suggested me to do the deed as she termed it, citing it would give the baby two parents and a larger family connection. Also adding giving her more grandchildren. I'm happy to assist and we all live together, my mother is the cares for the children, so their mothers continue their careers.
