I dont know if this fits exactly into the catagories you define, but I'll post it anyway. Iam not married, nor do I have a girlfriend or siblings, so my biggest fantasy would have to be tickling my two best friend's sisters feet. One of the sisters is a married 38 year old woman, petite with light brown hair. My friend tells me he has tickled her, but that she isnt that ticklish. The other sister is a very pretty 29 year old blonde, not married but in a long term relationship. The friend of that sister claims he has never tickled her, and has no idea if or how ticklish she is, even when they were little, which I find hard to believe. These are my top two tickle fantasies, since I dont deal with any other women in the catagories mentioned.
