Commission done by the lovely UsagiForehead 

Supreme Directrix Phantom and a rubberized captive! A lovely commission that came out great. 

-----

"Unit 39. Open mouth."

The unit didn't comply. An audible squeaking could be heard. It wasn't the rubbery, high-pitched whine of synthetically-treated material. It was the soprano sounds of a human; despite all the heavy gear, despite all the thick layers that now encased her, the human deep below was complaining.

"Repeat order. Unit 39, open mouth."

The experiment did not comply. The Directrix took her finger and traced the lips of her creation. It was soft, it was teasing, and the delicate sensation led the embedded drone to gently open up. 

"Hm... coated gums, tightly gagged, with reasonable penetration. Very good. Save this batch."

The only sound for a moment was the hum of the ship's machinery and Phantom's breathing. The aerosol-deployed device couldn't be allowed to spread throughout the facility, of course. The nanomachines were experimental at best; they had been reverse-engineered so quickly that they couldn't even be used for more benevolent purposes. No, it seemed that this sample could do one thing, and one thing only. It could turn the clothes and matter of an affected subject into a thick, impermeable second skin. Inhalation meant that subjects would soon find their stomach and throat coated as well, forced into a state of semi-stasis. Subjects exposed seemed just as much like dolls as living entities. 

Of course, the subjects had not volunteered. But such was the sacrifice to live in the stable, sensual lands of the Directrix. 

There was a bit more squeaking as Phantom put her finger between her captive's lips. She moaned a bit as their bodies touched, and reflexively seemed to suckle on Phantom's gloved finger. Behind her mask, the Directrix grinned, blushing red with pleasure.
