Ticklehorror has hundreds of clips on its site - many of which look great. I have even bought some despite the fact that I almost never buy clips without some decent form of toe tie.
There are many, many extremely vulnerable and immobilized upper bodies and legs on the site.
However, of the 1700 clips on the site, I can't find even one clip of what I consider decently immobilized feet. Which means clip after clip after clip of someone holding a foot with one hand while tickling with the other.
I do realize that many of the ticklees can't move their feet very far - but none of the clips has someone using one hand to hold the ticklees armpit still.
I have bought hundreds of clips in the last few years from various sites, and I would buy almost any clip of tickle tortured feet that can't move away from the tickling (like "Stuck in the Stocks").
In any case, Ticklehorror is more original and interesting than most producers.
Just my 2 cents.
