Jeezus Christ, do I miss working in offices -- for exactly this reason. I used to temp all over the city, and this was as close as I could get to recreating the atmosphere from high school when I used to get to tickle all the time. Dude, you've got the perfect set up: she started it, you're getting her back, and all you have to do is be patient...don't strike too early, don't waste the big opportunity by giving her little tickles every chance you get. Wait for the big kill, let her get you back a few more times, and save it up for the day when there's REALLY no one around and you can go to town on her. I ESPECIALLY love tickling Latinas...Nothing's better than a ticklish Neuyorquina, una bonita Boriucua...
