What he makes them do

John looked to the entranced Hayley and Kylie.

"Okay, ladies. When I wake you up, Hayley, you will believe yourself to be an interviewer interviewing Kylie here. Kylie, you will only be able to say the word 'Ass', and Hayley will only be able to say 'Tits', but you both will understand each other perfectly fine. When I say the word 'Serious', Kylie, you will orgasm, and Hayley will burst out laughing. But you will both still try to talk through your actions. When I say 'Normal', you will stop."

John woke them up.
