SO difficult to pick one. So ill mention two or three, lol. From MTP I would go with Ivy, would love to tickle Vivianna and the goregeous and wonderful Addie Juniper.
The model I would most love to tickle, and I know this is not original, is Priscilla James, although I would be a little fearful. I consider myself a ler now but got into tickling in the first place by being tickled, I fear how devilish she is, she may be the one woman who may be able to tease me into being tickled again too, and boy would I regret it.
