Amazing work by  SKY3 on this highly technical TF.
Your feet planting themselves and merging outward into a metal base, oozing together and outward like pancake batter. Your arms disappearing as your clothes shred and drop off you, revealing your insides twisting up and feeling hollow. But your head, it's not the feeling of it expanding like a bubble that worries you. It's the sensation of your thoughts rattling about. Of your personality, your knowledge, your hopes and dreams and fears and flaws and all the traits that make up you materializing into gumballs that your big glass head puts on display. Enticing treats. Pieces of yourself that you lose every time some passerby turns the crank. Another part of you sliding down your insides, out your chute into the waiting hands and mouths of random mall-goers. How many gumballs will you make? When will enough of you be gone that you don't even track.

From the other perspective, I need a good term or tag for when someone who doesn't have a kink or even has a turn off suddenly gains a kink. But like, not in a hypnosis way. In a more permanent mental change way. Cause a lot of those gumballs could lead to a sudden confusing horniness.
I'm using forced_kink but I've joked with a friend before about making an acronym, Sudden Onset Compulsive Kink. It's a bit too wordy to be a tag but while funny the acronym wouldn't seriously work either because it would be confused with the regular sock tag. Also it doesn't need to be a sudden kink. It could come on slow.

Addendum: Had a great idea when talking about this with Klao. The last thought, the last bit of personality is the gumball machine thinking of itself as just a gumball machine. So whoever eats that gumball, gets the thought "I'm a gumball machine". And that's how the TF spreads to the next person.
