Helpful Mother

In July 2023 I then 28 bought a rundown house about a mile from my parent's house. I started to renovate it as soon as its transfer was completed. Reroofing it first, then rewiring and replumbing it. With the major jobs done it was just the painting with some minor repairs here and there. Lastly, I'd the new carpets laid. Kitchen cabinets were old but in very good shape, custom real all wood not chipboard sanded and restrained they looked new. My mother then 47 was a regular visitor helpfully cleaning each room after I finished it. My father visited a couple of times, but never with my mother or when she was there. I sensed problems in their marriage, but neither said anything. Married to join two family businesses, they were stuck unable to divorce or they would be disinherited by their parents. They had separate lives slept in different bedrooms and only went to functions together putting on fake smiles. At the time it was easy when they had married, never thought they wouldn't along. Done as required as they saw their marriage, 3 children a boy (me) followed by 2 girls youngest now 22. Both worked for the combined businesses in different sections avoided each other as much as possible. My father had affairs my mother thought she couldn't, mostly not still she was passed having children. After that she couldn't relate to men at a personal level, most were already married, and others were off putting, and a couple were gay. Only unattached male in her life she got on well with was me, I'd girlfriends but couldn't settle with any of them at the time. It was the night of January first New Year's Eve parties were over, and my parents again went their separate ways. My father went off with his then current girlfriend, and my mother came over to visit me. She was lonely and I was unattached at the time. My mother helped me putting up curtains in the living room. Gifts from my grandmothers so they had to be displayed. They really suited the rooms look, better than the plain blue one I'd bought. I'd been only in my boxer shorts and T-shirt when I'd started removing the curtains and was preparing the new curtains to put up when my mother arrived. I stood on the step ladder, and she handed me each curtain as required. Of course, my being higher up than she was and only in shorts, she got a good view of my family assets. No comment was made while the curtains were being fitted, but as I finished the last one, she decided to play with my assets. I was surprised more than shocked as my mother is the straight lace type. Anyway, one thing led to another as they say, and we ended up in my bed fucking. It might have been just a one off, but instead it started a sexual relationship that is still going strong today. Over the time since we started, I met my now wife Married in September this year. She knows I fuck my mother regularly; she also joins in threesomes with us. Doesn't see my mother as a competitor, my wife is bi-sexual and has one on one sex with my mother. With my wife now formally confirmed as pregnant my mother staying over regularly is seen as anything more than a motherly concern for her daughter-in-law. Plus, it gives her more time away from my father and no gossip because of it. My wife's family live in the next state do visit about every 5 or 6 weeks on average, ever since we started living together in November last year. Perfect arrangement having my mother as a lover for both me and my wife.
