One day I woke up in the middle of the night and went downstairs to get some snack, I saw the garage light was still on. My brother, Ron moved into the garage since his room’s flooring was getting fixed. The door was ajar and I could hear muffles voices coming from the room. I knew these were sex noises, either mt brother was masturbating or banging a chick in his room. But to my utter surprise it was dad fucking Ron. I watched from the distance as dad pushed his thick dick into ron’s ass hole again and again.
