Full Body Replacement

Elektra winced again as the sharp coldness came over a far more sensitive part of her body. Two metal domes closed in on her butt, fitting themselves over her cheeks like they were made for them. They pressed firmly over each globe in a manner that...oddly enough, was playfully ticklish and pleasurable, especially as they slid into her cleft with eerily fluid smoothness.

So this machine just made a perfect mold of my ass. How about that? she thought with a small chortle.

However, Elektra's amusement didn't last long. As the butt plates secured themselves into place, she heard and felt something click behind her as they seemed to fasten themselves onto the stretch of metal attached to her spine. And then more nano-assembled metal began to clench down all around her body, encasing her arms, her hands, her fingers, parts of her back and stomach, and her neck. Even her boobs were not spared, the large orbs slipped over them as easily as a glove. Before Elektra knew it, just about her entire body from the head down was locked in a steel shell.

What is this machine doing? When will it stop? What's happening to me?

Long silken strands began to slide off her head and soon enough, Elektra's scalp was starting to feel cold as well. Her hair...it was falling out!

Her heart hammered hard into her chest as her terror mounted. It only grew more intense as a thin steel helmet lowered itself onto her now bald head, followed swiftly by what could only be a pair of flat discs over her ears. More plates pressed into her face, covering her cheeks, her chin, her forehead, her temples, her lips...it was like the walls themselves were closing in around her. And looking ahead, she saw what had to be the last things needed to cover her: a pair of dark circles lowering themselves into her eyes.

"No..."

She was about to be encased in a body-shaped cage of metal, unable to run, unable fight, unable to even move. She could only stand still and watch those horrid metal walls close in and imprison her.

"Help me," she said in the faintest whisper, which was the loudest she could force her voice to go. "Someone, anyone, Miranda...help!"

The circles pressed over her eyes and locked in place, blocking all things from sight. She willed herself to thrash, to scream, to rip this horrid suit off, but her body...would just...not...respond!

And then...she began to tingle. That familiar chill that was prominent everywhere else on her skin began to seep into her loins, where she was most sensitive. If Elektra could have bucked in surprise pleasure, she would have, but she nevertheless felt her inner walls clench in response to the sensation, almost as if there was something physically in there.

Except...something was in there. It wasn't being inserted as was the norm for Elektra; it was more like it was forming in there. Taking shape. Coating the inner pink walls of her sex, tracing over every individual fold, caressing them with that same almost enjoyable coolness that was swiftly becoming her companion. And unlike the rest of Elektra's body, her womanhood was moving, responding to it. Pulsing, clenching, and dampening. And as she felt her sensitive nub peek out from its hood, she just about gasped. Now it too was being nuzzled and massaged by the cool air and the unseen force with much of the same tenderness her beloved Miranda had given her in the past.

"This...feels...so...good!" she quietly moaned as she fought against her invisible restraints so that she could writhe around in her growing ecstasy, squeeze her breasts to generate that same electric feeling in her nipples, encased in their shell as they were, and to jam her other hand deep into her vagina just to deepen the pleasurable sensation.

"Mmm, mmm, mmm, yes!"

But it didn't stop there! It continued to expand the entire length of her love tunnel, coating every inch of pulsating vaginal muscle in its...whatever the hell it was. Elektra had no words to describe it. It was like the intense feeling she felt whenever she got the rare opportunity to run naked outside, to let the air blow freely into her open lips...but bigger! And more intense. And it kept going, hitting the rapidly dilating ring of her cervix, enveloping it...and going deeper still!

Electricity was now coursing through the steel-clad nudist. Not just in her sex, but everywhere! Every inch of skin, every individual toe, her hard and erect nipples, on the back of her eyes, and even in her chest, where her heart was beating. It was like every part of Elektra was being sexually stimulated...no, scratch that, every part of her was being sexually stimulated! And it was the most amazing thing she ever experienced! She didn't care how impossible that sounded. Just like she didn't care about the terror that had been gripping her not two minutes ago.

And she especially didn't care when the invisible restraints finally released her and send her plummeting to the floor. Elektra was too focused on her full-bodied orgasm to concern herself with that.

*****

When Elektra awoke, she was surprised to see that she could...well, see again. The slightly gutted chamber of the Prosthesis Assembler was all around her and looking as familiar as always, but it was once again illuminated by that soft blue light. That...was a relief she guessed. The door of the chamber was also open. That was definitely a relief.

It looks like it's over then. I wonder when the machine went inactive? It couldn't have been very long ago; she had only been out for 11 minutes and 54.76803 seconds. And how do I know how long I've been out anyway to such an exact decimal?

She shrugged. It didn't matter. Elektra spent more time than she cared about in this damn machine. She really needed to get out, go upstairs, find something to snack on, and maybe get some sun. As she pushed herself up, she couldn't help but notice the metallic clicks as her hands and feet pressed into the floor. Looking at her arm, she saw why: it was completely covered in metal! As was the rest of her body!

"What? What is this?" she asked, staring at her hand, flexing her fingers and noting with alarm at how they clinked when each individual joint bent. This was unreal, this was unlike anything she had ever seen. Everything, that is, except for all those robotic limbs littering the lab...

Elektra bolted out of basement and rushed straight to the bedroom, where the full-length mirrors awaited. She very nearly fainted again when she saw her reflection. What stood before her was a being that was just as alien to her as it was familiar. It had her exact shape, her curvy figure, even her large breasts. But every inch of her body, from the top of her head to the tips of her toes, was covered in silvery metal. And whatever wasn't, like the areas around her knees, elbows, armpits, and parts of her stomach and neck were coated in a dark rubber-like substance. But metal was present in those areas too, as evidenced by the wheel-like mechanisms jutting out of the rubber where her knees and elbows were supposed to be. Looking at them, they appeared to go so deeply into her body, they likely had to be digging into her muscles and bones.

Unless...

But it was Elektra's face that truly shocked her. It had the same humanoid shape she had always known, the same chin, the same jaw line, the same cheekbones, the same nose, the same lips...but like the rest of her body, it was also made entirely of gleaming metal. Even her "hair" was metal, though it could only be called hair in the loosest sense; Elektra remembered clear as day it had all fallen off in the Assembler, every individual chocolate-colored strand. Now, it looked like she was wearing a helmet of sorts that was designed to look like a bob haircut.

The only part of Elektra's face that could even be described as non-metallic were her eyes, and that was because they looked less like eyes and more like two gleaming yellow circles of light. To call them eyes would be a misnomer; they were really more akin to optical sensors, or cameras, or...

And that's when it hit Elektra. That's when it sunk in just what she had become. She wasn't covered in metal and rubber and plastic. She literally was metal and rubber and plastic. She was a...she was a...

"A robot. I'm a robot."

Elektra let that thought loop through her head again and again as she looked at her hands. Looked at how they gleamed in the light, at how her fingers flexed so gracefully even though they were now a series of mechanical contraptions made up of circuits, rotors, and wires. A sophisticated series of mechanical contraptions so segmented and articulated that the girl didn't feel any less dexterous now than when she had been a human.

She looked down at her body again, her graceful, metallic body. At a body that was no longer composed of flesh, blood, and bone, but of steel and plastic. Elektra had become a completely synthetic lifeform, a machine in the shape of a human woman, with not a drop of organic material to be found anywhere on or inside her person.

That thought alone should have made her freeze up in terror, but for some odd reason, Elektra didn't feel a single inkling of fear. And that wasn't because she couldn't feel fear or emotion anymore, because she most certainly could. And what she felt was...calm, like this was okay, this was normal, this was nothing to be alarmed by. That she was, in a way...fixed.

Curiously, she ran a hand up the length of her stomach, touching both the steel parts and the rubbery bits on either side that almost seemed to look like abdominal muscles. The tack sound of her finger tapping on the metal was predictable, but the fact that Elektra could actually feel her stomach on her finger, and similarly feel her finger with her stomach, was very surprising. Transforming into a machine had somehow done absolutely nothing to her sense of touch. And now that she thought about it, she could vividly remember how the air rushed around her as she ran nakedly through the house, the same as it always did when she was human.

Elektra trailed a hand up higher, until it came upon the underside of her breast. It did not squish in her grasp as it had before, and nor did it jiggle with her movements, but something about how it felt to the touch still sparked...something in her. Looking at her boobs, Elektra couldn't help but suppress an amused smile as she noted how even in their new metallic forms, they were still capped off with a nipple of sorts, indicated by a little nub surrounded by a dark grey circle that was likely meant to be her new areola. Curiosity beckoned the robot girl to see what would happen if she touched them.

A feel of pure electricity all but erupted in the little the nub the moment her palm brushed against it. Elektra could only lean her head back and murmur happily at the sensation it brought her. It was only interrupted when something started to prod into her palm. Lifting it up, Elektra couldn't help but giggle at what she saw. Her nipple had gone erect in a new way that was fitting for its new mechanical shape. Both the areola and nub rose a few centimeters, looking like a tiny piston rising within a larger one. And without even touching it, Elektra could already feel it become more sensitive.

It's like everything in my body has been replaced by a machine. Every little biological function and feeling...which must mean...

She breathed huskily at the sight of her crotch. Something about her new vagina, with the lights bouncing off both sides of her slit, made her feel fiery and filled her with an urge to masturbate. She slid her finger inside, which glided into the groove more easily than she thought it would, and let out a yelp. It felt...wonderful; her insides were soft and foamy, yet so familiar. By touch alone, she could identify the very same pulsating folds her fingers had graced so many times before in the past. And they were every bit as sensitive as she remembered, even though they were all completely synthetic. Everything, including her little love bud...

All rational thought left the robot girl. Leaping onto the bed, she spread her legs wide and prepared to see what her mechanical body was now capable of.
