Britney - Tickle or be Tickled?
I love this one! I'm primarily a ticklee, but I also LOVE to tickle girls. So one of my ongoing fantasies is, not having Britney, Christina, Mandy, Jessica, Pink and the like tickle-fight each other, but all team up to tickle the daylights out of me. Maybe make it a competition as to whoever is the least effective tickler (in terms of staggered "give-up breaks", like every couple minutes, till one of them is left as the least skilled tickler and therefore gets tickled alongside me by the other 4).
So aboslutely definitely I'd pick to be tickled mercilessly by Britney. Of course, I'd love a chance to tickle her in return, but I won't be greedy. I heard once she has a fantasy about a guy kissing her feet. Tickle torture me, Brit, and I'll kiss your feet and cute toes (yes, contrary to your own opinion, they are VERY cute) all day long.
