Bodyswap and rubber suit story

[earlofnexus]

Hi all

I'm looking for a story I can't find where a model agrees to model a latex suit but is tricked, and the latex suit once filled with a special liquid turns the wearer into a ski suit and their core essence becomes a waxy liquid that has to be stored in a tank.

There are multiple parts if I remember correctly.

Any ideas?

Thanks!

Yes, and she's kept in a tank for some time.  SHe needs to wear a latex suit to "keep" her form.

The evil doctor who tricks her is a man I recall
