In the Amazon Kindle Book Store I found 2 good stories. "Her Ticklish Side" and " Confessions Of A Ticklish Girl". 2 sexy stories with a large amount of tickling. Try them out.
I still had a pretty sizable amazon gift card hanging out on my account from Christmas and I bought this about a month ago. It isn't a short story like some of the others on there. It is a few chapters long. It won't be winning a Pulitzer anytime soon, but it was kinda fun.
