Hard as horn!

………………………..In the beginning he pushes in with gentle blows, then quicker, and at last with such force I could not doubt that I was in great danger. His member was hard as horn, and he forced it in so cruelly, that I cried out, “You will tear me to pieces.” He stopped a moment from his work. “I implore you to be quiet, my dear”, he said, “it can only be done this way; endure it without flinching.” Again his hand slid under my buttocks, drawing me nearer, for I had made a feint to draw back, and without more delay plied me with such fast and furious blows that I was near fainting away.
