In my mind I watched from a doorway as Father pinned her to her own mattress. The mattress we had shared on many occasions. Naked, he was pounding her hard and deep. She was screaming for him to get off. Clawing at his back and scratching at his face. Of course, Mother was of no use. She was sitting in the corner with her panties pulled aside, rubbing herself with a piece of left-over meat from an old meal. Sighing with pleasure as her eyes fixed upon what Father (husband) was doing to Sister (daughter).
