Not Sure Who The Dad Is

I am plagued with a terrible problem. A few years ago I allowed myself to be gang banged by a group of guys. Originally, it was two brothers (one was my boyfriend) and two of their friends. Later that same night, my boyfriend’s dad had a go at me too. For months he basically had been telling me that I needed a real man to fuck me. Once everyone went to bed he told me to come to the pool house where he fucked the hell out of me.

I have a three year old son. I really cannot 100 percent conclusively say who the dad is. It is a terrible secret.
