Fucking my Aunt

I was put up for adoption shortly after being born and years later tried to find my birth mother and had to go to court to get access to my records. I didn't even have a birth certificate. The Agency that handled my adoption was church based and refused to show me my file, hence the court case. I won the case, but my files were suddenly destroyed by a fire in their records office, which destroyed all their files. The person in charge had told me I would never see my file and was correct. Nobody was charged with causing the fire and I just had to accept I would never know my mother. I was 24 at the time and adopted parents had supported me and had the legal costs. At 26 I met my wife, and she was the youngest of 4 children and was 28 at the time of our first meeting. We went on to marry and have 4 healthy children. At the age of 50 my wife got very ill and needed a kidney transplant, I offered one of mine and after testing I was found to be a close match. My wife's older siblings were also tested, and her brothers weren't as close as me and her eldest sibling her sister was deceased. Intrigued I got a DNA test and my wife got tested also and we were found to be nephew and aunt. After going deeper, we found out my wife's sister had a baby at 15 and my wife was just over 2 at the time. The child was given up for adoption by her parents to the same church agency I had been adopted thru. My wife/aunt and I are still together years later only me and her know of our search. She is doing well with my kidney, and I can actually say I knew my mother. She was a a very nice woman who died in a car accident far too early in her life 55.
