There's a magical place in Itaewon, South Korea known as Hooker Hill. Inside one of the lil' brothel's is a beautiful Thai woman in her mid 30's who goes by the name of Kelly. She had this one piece outfit on, a big hole in the clothing exposed her midriff. While we were talking *ahem* "business", I lightly stroked her belly. She shrieked, giggled and we proceeded to negotiate adding tickling into our deal.
Lengthy tickle fights (which consisted of 90% me pinning her down and torturing her to my heart's content) began every one of my visits from then on. I would rank her ticklishness from very to borderline extremely. One time, when we were doing the other thing, I pinned her arms above her head and she yelped "Don't tickle!".
