🔮 Jack in a Fishbowl
Jack surely loves to attend various exhibitions where he gets to serve as a living decoration. This time he picked his best birthsuit to dress for the ball... 🎭
Being an exhibitionist,This substance by the way is something between rubber and glass. It gets more stretchy after staying in boiling water but while cooling down it shrinks and hardens to the state of organic glass.
The pressure from the contracting rubber-glass would be too much for a human, but Jack's main job is working underwater, so he has various mods in his body that help to withstand enormous underwater pressure.
In the end Jack finds himself trapped in the ideal fishbowl to experience what a fish must feel like in captivity...
Unfortunately, the glass would have to be broken with a tool to get him out but oh well, dozens of people admired the art, so it served a purpose! :3
Plus there is just quick and very obvious idea, but it just occured to me that image where Jack would somehow mastered this toy to the base...
yuni.us/anal-overheat
And would end up sitting on it with big belly bulge and horny face only he can do... whole exhibition would be quite hot :p
I know it is Nates niche, but good story could explain it...

I like your idea that getting compressed into a ball like this, maybe on Painproofen, could be something like a trip, perhaps practiced by the Torsorcerers as part of their magical training, somehow greatly empowering them... And I don't think it's only Nate who gets to try the mega toy, for a limbless body like Jack's it seems even more obvious ^^

Was dreaming whole past day/night about how to develop your superb ideas and agree this event should be full fledged exhibition with more pieces! Most of them using same "glass" material Jack is in.
As visitors goes... what about making whole event super interactive?! Visitors will not be able to touch pieces directly or leave prematurely, but they could instruct also present "drones" which looks just like one in the middle yuni.us/noah-integration-wip to skillfully perform any kind of pleasurable ideas on ie Jack's cock n balls. This way every one would be pleased without even slightest possibility of unintentional bad "pokes" or eventual boredom for exhibits.
(Such events could be often done for educational purposes for youngsters which are still shy of freely experiencing pleasures despite being old enough already... sometime going at it with parents.)
Of course visitors would get horny beyond belief just watching such divine pleasures... but only allowed way how to relieve would be to become temporary (hour or so) exhibit themselves. So upon willingly stepping into beam of energy their hands and legs would be swiftly and painlessly disconnected by flash of light... and would as their own now limbless bodies levitate at one place in the air.
Now hihi :-D the tables would turn as those super experienced "exhibits" would be telling drones what to do with new "colleagues"... leading to repeated "eruptions" and sexiest moans in front of every other visitor. Not only any bashfulness would always vanish but many would be enamored by limbless (and of course contortionist) way of life. Now for those with real passion which visited exhibition multiple times there would be one free painproofen trip in ie Jack's ball as sort of "weak" teaser what you can achieve and experience every single day... .
Better yet some visitors would wonder if there is a way to become one of those indestructible and pretty drones (of which one is art piece itself doing impossible bendy pose). And to big surprise of few who actually inquired there indeed was a two step way! First step would turn you into familiar face (a clone) you saw so often helping you selflessly with everyday problems yuni.us/noahs-ark Such commitment was reversible and really all it did beside lending you ageless clone body was rewarding good hearted effort with waves of pleasure... . Now if one wanted to really help society in meaningful way while getting godly body and same state of mind there was step two... .
*Buzzing drones would always lustfully clean otherwise pristine floor by their tongues after each "eruption".
ps: Long story: I really hope it won't disappoint you because it is different that your worlds *I know :((((*, but I did really tried to show some "possible" way for better outcome even from dark future... and most of all "polish" sentences so they are easy to read and spark imagination of audience (way way! harder than simple ideas).
Once again thanks for everything
pss: Megatoy - haha it would be fun to see how his face expression change as he is slooowly sliding and making his way to the base. From joyous -to- bit afraid -to- shocked -to- savoring -to- super lewd as he just discovered WHOLE new dimension to simple indefinite sitting X-D
