One Bar Prison

So I kind of had this bright idea, since I'm into bondage as well, that using a One Bar Prison in the process of tickling would be an insane yet very good idea. I assume some don't know what a One Bar Prison is so here goes. A one bar prison is a single mounted pole that goes into someone's butthole. If the person is wearing heels or on their toes, it's quite difficult to escape, hence it being a one bar prison. You'll usually (I think always) see a female on it, haven't seen male yet. Anyways, back to my idea.....

I made up a random image in my mind the other day where a girl (assume she is in her adult ages) would be on the one bar prison in high heels and her legs would be tightly mummified around the pole up to the waist, restricting her ability to move her legs from the pole as well as inability to bend her legs. Her arms would then either be tied/chained up above her head or bound behind her back, exposing her entire upper body for tickling. What happens when the girl is tickled in this position? Well, she only has two possible options:

1) She stands there and takes it
2) She tries to avoid it by bending back or forth, left or right

In either case, there's no escape from a tickler's fingers. Just a random idea I had, lemme know what you think.

PS: Yes I know, this is kind of cruel and probably pretty sadistic and evil, but that's the whole idea because a sadistic tickler in the "business" of tickle torture
