When I was still in highschool I was at home in bed one night and heard odd noises from my parents bedroom. Now I know what my parents sound like when they have s** and this was different. So I went down the hall and found my dad screwing the neighbor. The next night I confronted him about cheating on mom and he said he would do anything to keep me from telling mom after she got back from visiting her parents. So I made my dad screw me too. I had always been curious anyway and after seeing his p**** the night before I was honestly aroused by it. Ever since that day my dad and I have had an affair that no one knows about and it has lasted two years of highschool and all the way through college. I even would be with my dad during my own relationships.
