Snippet from book (those of you who read the book know the setup to this):

“Why did I wait until today? Because I first wanted to hand you over to other men. Now I shall punish you for it. I’ve never punished you, O.”

“But I belong to you,” O said. “Punish me. When Eric comes…”

An hour later, when he was shown a grotesquely bound and spread-eagled O strapped to the two columns, the boy blanched, mumbled something and disappeared. O thought she would never see him again. She ran into him again at Roissy, at the end of September, and he had her consigned to him for three days in a row, during which he savagely abused and mistreated her.
