When I first started realizing my interest in tickling, I was definately more interested in the ler side. I still am interested in the ler side, but my biggest fantasy has changed. Sadly, I haven't had a chance to play any of these out yet.
My biggest fantasy right now is to be tied down and tickled by an attractive female with some well manicured fingernails. She would be tickling me for information, either the answer to an embarrassing question that I didn't completely want to answer, or perhaps we would be role playing and she would be trying to get a password out of me. She would go after my upper body relentlessly, my underarms, ribs, sides, and stomach. She'd experiement with other places too (unfortunately, my feet aren't very ticklish and my fantasies are starting to accept that, but she'd still try them out!) She would also be verbally taunting me, telling me that I would break eventually and reminding me of how ticklish I am. She might also say, "If you don't tell me now, I'm going to gag you and tickle you for five straight minutes, so you'll have no chance of refuge during that time!" Part of the excitement would be seeing how long I could last. And when I finally did break, she'd tickle me a little longer just for making her work for it.
Now, I still have fantasies about being the tickler too. Having a girl with ticklish feet tied down in the same situation would be great. I would explore other areas as well, of course!
To think, we could have competitions to see how long we could each take being tickled - that would be excellent!
