Shocking by my one-night stand the affair afterwards

A little history first, my parents divorced when I was 5 and my mother took me away. Against court orders and so we kept a low profile for many years. Then my mother died in a car accident, and I was 21. I was a trained mechanic having left school at 15 and so with my mother gone. I decided to find my father, I wasn't allowed to ask questions about him growing up. So, checking thru my mother's papers I at least found the town I was born in and my father's name via my birth certificate. Thru an online search, I got a job as a mechanic in the town and so traveled there to scope out what family I still had there. My surname spelling was changed by my mother years before. So, my father's family wouldn't connect we were related until I was ready to reveal myself to them. Years of my mother's stories made me want to be careful at least at first. I travelled by car across 4 states to get to my birthplace, having not made any enquiries about my father online or other ways. Not wanting to tip off tip him off, in case it showed somehow. Arriving in my birth state and it was getting dark and still a fair way to go. I planned to stop at a motel at the next town. As I approached the outskirts of the town, I saw a car with its bonnet up. I stopped asked the lone woman 47 if she needed help, she did, and her cell phone was flat also. I checked over the car and found a wire loose and reconnected it and that fixed the car, she offered me money I refused. But asked if she knew a motel in the town she did and she said she would be staying there also. I followed her to the motel and got adjoining rooms and went to the nearby diner for a meal. On our returning to our rooms, she asked me to sleep with her. I'd nothing else planned and agreed, we fuck twice and again in the morning and showered together and then had breakfast together. She left to do some work, and I continued on my way. Arriving at my destination a couple of hours later, I went to mechanical workshop I had the job with and then to my rented room I'd arranged. Started work the next day Friday, I wasn't supposed to start till the following Monday. But they were shorthanded, so I started earlier. In the afternoon the woman I'd helped came in to book her car for a service and a full check over as it had played up on her on her work trip. I saw her before she saw me, my new boss called me over and asked me to service her car on the Saturday morning. She recognized me straight away but said nothing, the boss and his other employees had had the local high school away football game to see. That's why I got selected, next morning I opened up the workshop and she arrived a short time later. Then she went shopping while I serviced her car, I done the service and found nothing much wrong. Except a wire harness had been cracked and broken loose and had dragged a wire off its connection. No replacement harness available, so I glued and screwed to a piece of tin and connect the tin back to harness's usual place. Plastics don't last lost especially in next to hot engines. She arrived back loaded with parcels, after putting everything in her car. She asked what I'd planned, nothing was my answer. She smiled and gave me directions to a small out of the way house outside of town for some fun she said. Then she left after I had agreed and said I'll said be about an hour. I locked up the workshop and went back to room showered and then headed off to find the house. It was out of the way alright which made it easier to find as there were no other buildings in the area and out of sight of the roads in the area also. She arrived about ten or so minutes later and we had sex twice before she had to go. This became a regular meeting place for us over the following weekends. Anyway, I also focused on my father and located him fairly quickly and he didn't seem to be the ogre my mother had made him out to be. The more I found out the more I wanted to meet him, but I took my time. Finally, I reached out to him first by letter than by phone, once I was ready, I met him. We soon were getting very well, and he was saddened to hear of his ex-wife's death, and I was welcomed to dinner with his new wife and family. At the Friday night dinner, I met my father's only sibling his younger sister and she was the lady I'd fucking for several months. I was shocked and so was she, but we kept it hidden. It didn't stop us meeting the next afternoon and fucking still. We weren't really put off by our family relationship, as we were strangers before we started. It was for our mutual satisfaction, her husband a state senator who mostly ignored her and was ten or so years older than her and was rarely home. She kept busy doing work for his voters to keep them voting for him. Their children were either at university or making their lives alone at night mostly and they had granny annex on the side of their home. His late mother had lived there till she passed away. At my aunt suggestion my uncle offered it to me to live in instead of the rented room and my father's family live just a block away. I've now settled in and have met my cousins and I'm still fucking their mother every chance I get. Otherwise, I'm single and looking for a girlfriend and yet to find one, but I'm not in any real hurry either
