This is almost exactly like the "Flanders Bench" idea that
Kujman1 envisioned over twenty years ago. Allow me to explain:
A willing, barefoot ticklee (let's call her Jennifer) lies face down on a bench, and she is physically bound to it. Jennifer can't move at all. Her feet hang off the bench.
Behind her is a video camera. It's not recording anything, but the feed from the video camera is sent to a television screen that is positioned RIGHT IN FRONT OF JENNIFER'S FACE. Jennifer can see HER OWN BARE SOLES RIGHT IN FRONT OF HER.
(The ticklers or riggers may want to restrain her head so that she can't move it much at all... which means that no matter how much Jennifer tries to turn or twist her neck, the television screen WILL ALWAYS BE IN VIEW.)
Then, of course, the ticklers go to town on Jennifer's feet... and Jennifer is witness to all of it. Up close, and in living color.
It's a GLORIOUS mindfuck.
I got to witness this IN PERSON at a tickling gathering that I co-hosted with my then-wife in Albany NY in the spring or summer of 2001. A local ticklee (let's call her Michelle) knew about the Flanders Bench, and she had been fantasizing about being in it for quite some time. Michelle JUMPED at the opportunity to get into it when she learned that Kujman would be at our gathering.
We were not able to get and/or position a television right in front of Michelle's face, but that led Kujman to a better idea. He paid Rent-A-Center WITH HIS OWN MONEY for a big-screen TV (remember that this was 2001, before flat-screen TVs existed) for this purpose. We put it at the opposing wall of the Flanders Bench, so that not only Michelle could see her bare soles being tickled, but that also EVERYONE ELSE AT THE GATHERING could see them as well.
Michelle was mercilessly tickled on her bare soles for an hour, and she loved every second of it. I will never forget her laughter.
Also -- and you can confirm this with anyone who was there -- it was obvious from the noises she was making that she had at least seven orgasms during that hour. (No genital contact. That's how sensitive Michelle's soles were -- and probably still are. One of the first things I learned about Michelle is that her feet were a MAJOR erogenous zone.)
Ah... memories of my twenties. I used to have them often... but now I control that with medication.
A decent picture of the original idea of the Flanders Bench can be seen near the top of this thread:
