For me? I would prefer to be Rendered fully immobile by many layers of heavy bondage(My body fully bound from head to toe with rope). On top of this, I would like to be blindfolded, have my ears plugged and mouth sealed so that I could feel the real intensity and torture of the tickling. Then I would have my shoes removed and my toes individually tied back. After all this, a tickle domme with long, sharp nails could start from my big toe, drag her nail down the toe, and down my arch and stop at the heel, trace the outline of the heel, drag her nail back up the outer side of my foot, across my toe crevices, and back to my big toe. This cycle would be repeated many times, while I lay there perfectly still under bondage, blind and dead silent from the gag. The only sound in the room is the sound of the thickle domme's nails lightly caressing against my soles. But realli, I am SUFFERING the torment under the heavy bondage, my body straining to the limit to escape, and my tongue pushing against the gag to that I can scream.
