Even i would not be sure where to start tickling but rest assured i would tickle and the lee wouldn't get any rest.
I favour a kneeling on table hands together over head arms streched up high, fastened to a roof beam legs kept apart by leg bars at knees and ankle only shins and front of knees can't be reached.
But this form of hog tie comes a good second best i have used the face down on the bed hogtie and been tied that way myself, when your face down and your feet and thighs are tickled and you can't see whats going on or break loose or move much it gets a bit scarry 🙂🙂
Thanks for sharing
