I had a g/f a long time ago who was cute, petite and could control her ticklishness... unless you caught her by surprise! One time I had her tied up spread eagle and tried all the usual spots and nothing! Arrggg! Then the Domino's guy rang the doorbell and I went and paid for the pizza. By the time I got back to the bedroom, she had squirmed out of her bonds and was getting dressed. Little did I know then, I think she was getting close to loosing control. Another time, we were at her house and were laying on the carpet in the finished basement. I got her in the hold laying next to her and held one arm up while the other was under me. I started tickling her armpit and she immediately went ballistic! The only bad part was she started banging her heels on the carpet. Trouble is, carpet doesn't pad you much from the concrete floor. She bruised her heels and I stopped tickling her. Why couldn't we have been on a bed or couch? Oh well.
