The best line I have had used on me is, " I will take you to a point of pure tourture. You will beg me and I will ignore you." That made my senses go nuts. I am a very nice guy. Those who know me will tell you I am kind. When it comes to tickling someone, I can get a little evil. Before I tickle someone I love to get my hands and face close. Then I say softly, " Are you nervous? Do you feel helpless? That is good." Another one is, "I will tickle you. Of that there is no doubt. The only question is, Where do I begin?" Make sure there is a long pause here as you hover. Keep them guessing everyone. Aways remember to respect your 'lee however. If they trust you, they will relax and enjoy it.
