Ultimate Embarrassment

When I was 16 my parents started having marriage problems. A lot of arguments and constant tension. Then one day mom revealed to me and my younger sister that she was pregnant. OK, whatever. Shortly after that dad moved into the spare bedroom.
The day they went to the hospital for birth I stayed home and watched my sister. Dad came home that afternoon, packed some bags and sat them by the front door. Two days later mom came home with the new baby. The baby was black!
Dad took the bags and left. As bad as this was it got worse. Dad filed for divorce and it got messy. I was exposed to the details and it was bad. Apparently the real father of the baby was a high school kid I knew. He was a senior but DAMN!
After the secret was out he started coming around to see the baby. Actually I don't think he gave a crap about the baby, he started coming around to fuck mom. Mom would take him and the baby into the bedroom and lock the door.
Word got out in school and my life was miserable. I went to stay with dad and changed schools.
