Benevolent non-consensual. When I tickle somone it's definitely a greater kick if the guy can do nothing against the tickling, struggles, begs me to stop etcetera. I love exceeding the point where the lee would, if he could, stop the tickling. However, as soon as I sense that the lee is seriously not anymore enjoying it I have no desire to continue. Same holds in return when someone tickles me. I love to be powerless and at the mercy of a skilled relentless tickler. However, as soon as I feel he is totally ignorant of my well-being it's an immediate turn-off for me.
