Liquid nitrogen

Rocketgirl awoke with a jerk when her latex-covered body was plunged into a hypercool bath. She flailed a bit but her movements were restricted by both the tight latex bag and the hypercool slush surrounding her. She screamed in reaction to the dramatic temperature drop but the sound was muffled by the gas mask surrounding her face.

She couldn't see anything; though Ms Jensen cut holes for her to breathe, the black latex still covered her eyes and ears. She could hear the faint, muffled sound of her own scream and the liquid sounds of the hypercool slush surrounding her, but had no other sense of her surroundings. That is, until Ms Jensen's voice emanated clearly from earbuds implanted in her ears.

"Best get all that useless struggling and flailing about out of your system now, Rocketgirl," Ms Jensen taunted. "The slush mixture you're floating in now will allow you those movements. But I'm using it to lower your body temperature to the point where I can introduce liquid nitrogen to the inside of that fetching latex catsuit without fear it will boil when it comes in contact with your skin. I'm going to freeze you, Melissa. When your body temperature reaches 77 degrees Kelvin, I'll pour liquid nitrogen into the hose connected to your navel. I'll flood your tight little catsuit with enough liquid nitrogen to coat your sexy body. The latex is thermal so it will keep you and your liquid nitrogen coating perfectly frigid. You'll be absolutely frozen solid thanks to the coating of liquid nitrogen. You won't be able to move. Then I'll lift you out of that slushy tank and you'll have to keep perfectly still to avoid causing yourself to shatter. Wouldn't want the great Rocketgirl to go splintering into a million little liquid nitrogen pieces, now, would you?"

Rocketgirl's motions in the hypercool slush had diminished to almost nil, her muscles constricting so tightly she felt she might crush herself. There was almost no give anymore. The slush may as well have been a cage of diamond or ice around her.

"According to these readouts, you're almost there," Ms Jensen remarked. "I've got my hand on the valve for the liquid nitrogen and I'll be ready to turn it in three, two, one..."

Rocketgirl heard the metal squeak of the valve turning and felt a liquid cool sensation touch her navel. She was surprised that it didn't feel that cold now that the rest of her body was frozen. That's a small relief, she thought. At least I didn't jump back from it and cause it to scar me yet.

The smooth latex guided the incoming liquid nitrogen around the contours of Melissa's sexy body. Powerless to stop it, Melissa felt a mildly pleasurable tingle as the nitrogen licked languidly down her long legs and between her toes. She felt it cool and coat her breasts and up her neck, lapping at her chin, her nose, her eyes. Were she not already frozen, she'd have squirmed with pleasure as it teased her pussy lips and seeped into her vagina and her pert butt cheeks. The liquid nitrogen continued to pour in after it had coated every inch of Melissa's beautiful body. After a time, it stopped, and she sat there motionless and frozen, suspended in a pool of liquid nitrogen within the contoured catsuit suspended in the hypercool slush.

"And that's 100% saturation point reached," Ms Jensen informed her. "You thought you couldn't move before, when you were simply suspended in the hypercool chamber. Now you really can't move. The famous Rocketgirl, once the fastest, most mobile creature on the planet. Now a perfectly preserved, frozen statue. Let's see if you can keep still when I take you out of that tank."
