My brother's wife's aunt

I (27) didn't go to university like my siblings and became a mechanic and also cleaned up people's yards on weekend for extra cash. Working Monday thru Friday in a large workshop and fixing cars or cleaning yards on weekends had allowed me to buy my own house with large shed behind it. As I was on a corner lot, I could enter my yard from the front or side. With a pickup and large trailer, I could handle just about anything domestic. I hired equipment if needed, not great on the dating scene, but had my moments. Last year in October, my sister-in-law (Sil) asked me to help out her widowed aunt. Who yard was very overgrown and needed clearing, her aunt was in a wheelchair and had her only child a daughter 25 living with. The daughter was very shy I was told and just went to her job and then straight back home. Meeting my brother his wife at her aunts place I was introduced to the aunt I saw her daughter but didn't get to talk to her. Her main problem was vines that had come into her yard and climbed over everything and most of the yard was covered with them. I started that day mainly cutting the vines to kill them, I knew they would regrow. But with the dead parts removed I could track down their roots to pull them out. I returned the following weekend to remove the dead vines and pull out any roots I could find, I found I could coil the dead vines and get more onto my trailer that way. I also found vines that hadn't died and cut them, when I was finished that day at least you could a great deal more of the yard having made 3 trips to the dump. Next day Sunday cleaned up anything I could and removed more roots I found; I had pulled down the dying vines and the yard was clear of them at that time, but they would regrow from roots I hadn't found, or seeds left in the dirt. I planned to drop by every now and then to check. It was when I was getting ready to leave the aunt asked me to have a quick look at their car. I did and it mainly needed a service nothing major and so I said I would come after work on the Tuesday and do it for her and only charge her for parts/oil. As I service their car on the Tuesday, I was invited to have dinner with them. I also got to talk to the daughter albeit briefly, asked by the aunt did I do any handyman jobs. I said I could as I'd done up my own house after buying it. I saw what she required and said I would do the next weekend. I arrived Saturday and started fixing the cupboards doors and leaking taps. Nothing major and I wasn't going charge them as it wasn't that much to do, the daughter was away that weekend visiting her aunt my sister-in-law's mother with Sil. When I finished the aunt asked me to do one more job and I asked what job she said, me I'm very horny. She is very good looking for her age and I decided why not and that took care of the rest of the weekend fucking my SIL's aunt. Of course, we continued every chance we got, like when her daughter was out shopping with her cousin. It was always arranged earlier, and I would turn up to check the yard for vines and when they left, I would fuck the aunt. In April the aunt asked me would I like to marry her daughter; the daughter takes after her mother, and I said wouldn't refuse but would the daughter want to marry me. I was told the daughter liked me only needed a push her mother said. I asked by whom, me was her reply and I was invited to dinner the Friday night and told I'll be staying all night. I agreed but doubted it would be that simple. On the Friday night after a nice dinner, we talked a while. Then after a while the aunt said I'm very horny and want fucking looking straight at me. I was shocked and looked at her daughter who was shocked also, I think. But her mother added we make a threesome of it as I want some grandchildren. She was looking straight her daughter we she said it, you two can marry afterwards she added. To my surprised the daughter wheeled her mother to her bedroom and I just followed. I fucked both, the daughter once and her mother twice and fucked again in the morning. Only stopping because my brother and his wife arrived with their 2 children. I quickly dressed as did the daughter, her mother only put on a night gown. My brother was surprised at the news I was marry his wife's cousin, but happy with the news anyway. In late May we married, and all started living together in my home. It suited my now mother-in-law better than her own home which they sold. My wife was pregnant by July and her mother regularly sleeps with us still. Will take care of her granddaughter when born while we work. Strange start to my marriage, but I'm happy with the outcome.
