With the gem now fixed on her chest, and Mira obviously reaching a kind of no-return point, you decide to try one more time to break her from the gem's effect. But this time, as you touch it, you can feel a spiky reaction from the gem, like static electricity.
"What now ?"
As you instinctively back down, wondering if that mean you'll soon suffer Mira's fate, or how what is supposed to be a rubber stone could shock you, you finally notice a change in Mira's situation : her body stopped glowing, she seems finally out of her trance, with the gem, now purple, still attached to her chest.
"Don't worry, I'm fine" she says, seeing your clearly panicked face.
"Thanks God... Now, can you remove this gem ?"
"Why would I ?" Something is still wrong with her.
"Because it's dangerous ! People aren't supposed to glow like this !"
"But... It's me..."
It's you ? This last reply has brought your concerns back...
Suddenly, Mira start to breath heavily, as if something is straining her. You notice then a shift in her clothes color : most of her uniform turned completely white, with her socks, sleeves and bow turning purple, matching the gem's color. It also look like her uniform changed material, as it now has the same shine as latex, again, like the gem.
At this point, you gave up separating the gem from Mira's body, you're more interested in seeing the end result of all of this. On the other side, Mira seem quite pleased with her situation.
"Not bad, you should try it"
"That's it ? It changes your uniform into a latex fetish version ?"
"Don't worry, it's not over yet !"
As an answer, the (now) white part of her latex uniform liquefy, spreading over her body and covering any exposed skin up to her neck. Her sleeves then do something similar, and forms some kind of long purple latex opera gloves. To match her new gloves, her usually short socks climbs her legs, forming a pair of purple latex knee high thighs. Her shoes disappears, or at least are absorbed by her new thighs, as they lack any traces of her toes.
"That feel good ! You should really try this ! And we're not even in the good part !"
"But why the latex bodysuit... Wait... You know what's happening to you ?"
"Just watch..."
As she close her eyes, clearly enjoying herself, her new bodysuit start changing once more. This time, it tightens around her body to create the most form fitting bodysuit ever seen. Actually, form sculpting seem to be a better term, as with every passing second, Mira's overall figure changes, gaining more curves, until it become almost surreal, looking more like an exaggerated, ideal version of her old body.
As it happens, purple latex bursts from the top of her head, covering her hair, flowing until it form a long haircut made of seemingly liquid purple latex.
Mira's face then slowly loose it's color, matching the white of her body, and gains the same texture as her body, until it's impossible to make a clear difference between her face's 'skin' and her latex covered body. All of her face's imperfections disappeared, as if absorbed by the latex, her eyebrow now drawn on her face, instead of being made of actual hairs.
As far as you are concerned, she is either wearing the tightest, full-body suit, covering her face and hair, or she is now naked and her body is now made of latex, with her most private details smothered. You can't even tell if her gloves and thighs are actually distinct items, or if they are only a colored part of her body.
With her face's transformation over, Mira's eyes open, revealing a pair of finely painted purple eyes, lacking the usual spark of life she had before.
As she stays immobile for a few seconds, you notice that she stopped breathing. Where Mira stood before, there is now a beautiful but lifeless white and purple, technically naked, latex doll staring at you with Mira's face. You start to panic, fearing the worse for her.
"Are you okay ? Please, say something !"
