I used to work with a girl, we'll call her Katy, and she was beautiful and cute, which is a rare combination, and I fell in love with her immediately. I wanted to date her but we were both with someone and she probably wouldn't have dated me anyway. But I am a cunning son of a bitch, and I had to tickle her, so I devised a plan (no I didn't, I just asked her if I could tie her up and tickle her.) She agreed for some reason, and right before we parted I asked, so are you ticklish? She said, Oh my God, that's like, my weakness! Right! Turns out she was the most ticklish person I have ever met or tickled in my entire life. And she loved it. I have it all on tape but it's a private tape so don't ask. Sad thing is, afterwards, whilst watching the video, I noticed that at one point she said, and I quote, "This is awesome, I'm so ticklish." Didn't notice at the time, but hell, had I? Man, it could have been a running thing. She loved it! Had I not been so overwhelmed by the insanely lucky position I was in, I might have noticed.
