This crudely drawn diagram will be the implement of your demise! XD
(hopefully it isn't too small to see)
Basically it's like any normal rack, armslocked about your head, waist held down and leg locked in place.
The only difference is that the right leg restraint is replaced with a shackle. >;D
you see, when I begin to tickle someone, I will concentrate on their right foot alone.
The object of the 'lee is to not move their right foot away from the tickling, because if they do, they'll pull the rope which the shackle is attached to and this inturn switches on all the feather drills! XD
Basically, the longer the 'lee can endure the tickling, the longer she can delay the inevitable! XD
So what you think Sammi, wanna give it a try? 😛
