The 23 best / worst Bad Sex in Fiction award winners 15. The Castle in the Forest by Norman Mailer (2007)

Klara turned head to foot, and put her most unmentionable part down on his hard-breathing nose and mouth, and took his old battering ram into her lips. Uncle was now as soft as a coil of excrement. She sucked on him nonetheless with an avidity that could come only from the Evil One - that she knew. From there, the impulse had come. So now they both had their heads at the wrong end, and the Evil One was there. He had never been so close before. The Hound began to come to life. Right in her mouth. It surprised her. Alois had been so limp. But now he was a man again! His mouth lathered with her sap, he turned around and embraced her face with all the passion of his own lips and face, ready at last to grind into her with the Hound, drive it into her piety.
