Lucy sat slumped in her chair, her chin on her chest.

"Lucy, whenever I tell you to sleep, you'll fall back into this trance. Understand?"

"Yes," said Lucy sleepily.

"Lucy," said John, "if I make a suggestion, you'll think it's a great idea and act upon it. Understand?"

"Yes."

"Lucy, if I ask you a question, you'll respond with an enthusiastic yes no matter the question. Understand?"

"Yes."

"Lucy, the sound of my voice makes you horny for me. The more you hear my voice, the more sexually attracted you'll become to me. Understand?"

"Yes."
