Although I started out a foot tickler, over the last few years I've grown into a underarm tickling fan. The underarms are so soft to touch. Once doing a night of lovemaking, I pinned my girlfriend hands above her head and began teasing licking her left underarm. I drove her into hysterical laughter with this fiendish tickling. She paid me back for the tickling by jumping on my back, tickling me without mercy on my ribs.
