" Fucking is an art. The mere fact of introducing the cock in the cunt and moving it in and out until the ejaculation of spunk is not art. True, it is fucking, but the difference between that way of doing it and the way it should be done, is like the difference between a child's first drawing and a picture by the world's greatest painter. "
