Awakening

My dad is dead now and my stepsis is married with kids.

The first time I saw them was when I was 8. I was walking home from school and saw my dads truck out front. I was so excited that he was home I ran to the door and opened it. My father and my stepsis were fucking in the middle of the family room. He was holding her with his forearms under her thighs his hands gripping her ass as his cock was clearly visible in her pussy. he gasped and turned around and ran to the rear of the house, still holding my sister , his cock deep inside of her. She was 13 and that was the first time I saw them.
