I think people who are into tickling but are also masochists (me) get to experience one of the most interesting things during tickle torture sessions.
As a knismos I enjoy tickling (even if we all pretend I don't) so it doesn't really speak to my masochistic side, at first at least.
Tickling gives me this giddy giggly feeling, butterflies, silliness, all the fun stuff. If you're a lee and got tickled you probably know what I mean.
But when the tickling keeps going, gets more intense or targets spots that are really bad, things change a little.
There is this moment between knismo and enjoyment and masochist enjoyment that changes the experience completely. Like a scale slowly tipping there comes a point where it goes from "This is fine" to "I can't take this".
I once went cliff jumping (don't do this I was young and stupid) and the moment between m, feet leaving the cliff and me hitting the water felt like I was floating between worlds.
It's kinda like that, a drop in the lit of your stomach, suddenly your brain fires, everything screams to fight back and get away because the tickling is too much, too overstimulating.
It's the moment where I genuinely try to get away, not because I want to, but because my brain tells me to. It's www hen I beg and scream between laughter, hoping my ler will ignore it and just continue.
And then tho other side of the scale hits. It's to much, but it is so good. The bliss of your brain swimming with nothing but thoughts about how much it tickles, a feeling like you are going right over the drop of a rollercoaster again and again.
A feeling almost similar to subspace where your world is nothing but tickling, and you have no control over it ending, and that fact makes your whole existence pure bliss.
