>This head and feet in stocks or a wall setup
I know this is kind of the wrong place to say this, but I actually really like this setup, even as a guy that doesn't get off to feet exclusively. It's not without issue; it can very easily devolve into an excuse for artists to be lazy (and it often does/has), it makes me terribly worried about the 'lee's spine and the goomba example proposed is actually nightmarish. And still... I see the appeal.
As a pitfag, one of my favorite parts of tickling that spot is that it allows the 'ler to be up close and personal with a 'lee. There's something really special about getting right in their face and observing every detail of their expression as the tickling drives them wilder and wilder, it gives the chance to look into their eyes as they wordlessly plead for mercy in ticklish anguish or to passionately make out with them and literally feel the giggles coming out of them. Now, feet are based, but they're also literally the furthest you can be from allowing the same thing. So, this position solves that. It combines one of the advantages of pit tickling with a different tickle spot and I can appreciate that, even though pits are still typically what I'm gonna go for when I want that.
I'm also a big fan of single spot tickling. Full body stuff is insanely hot, don't get me wrong, but the oppossite, a 'lee having a single spot targeted and that
being enough to completely break them because they're just so fucking ticklish there, really does it for me too. And this setup exploits that to its maximum degree: the 'lee has been reduced to the body part being tortured and their one outlet for all the crazed reactions. Their entire world is that spot and all the torture being forced upon them through it, it's the only thing they can think about, it's the only thing they're allowed
to think about... And although, truth be told, I think mummification does this aspect one better because it shows the bondage that's denying the 'lee any contact that isn't the tickle torture going on (and it opens it for different spots to get the works instead of feet too), I still really like it here.
And finally, when I'm feeling a bit edgier and I want some of that dark, messed up tickle torture fantasy stuff, the whole 'mounted on a wall like a trophy' thing that often accompanies this setup is pretty fantastic too. It's dehumanizing, it's psychologically scarring, it makes sure the 'lee feels like nothing but a tickle toy whose value lies entirely in their suffering for others' entertainment. They're literally nothing but a body part to torture and one to hear and see them go crazy. It appeals to that filthy part of me that wants to know the 'lee is suffering hellishly and tasting ticklish despair. And yeah, it's not associated with this 'trope' of sorts necessarily, but whenever it is, it's a huge plus.
Alright, that's enough of me playing devil's advocate. Don't let me stop you from disliking it, I totally get why it's divisive to say the least and yes, it is totally overused, but I don't think it's just footfags that genuinely only care about feet that can find it appealing.
