It was admittedly rather an odd way to spend his free time, but Mattias felt drawn to such webpages, beguiled by what lay therein. His eyes flickered back and forth over the screen, wide and attentive. This sort of thing was the young cat's favourite obsession, and while he wouldn't call the robotics catalogues a fetish, he had to admit that the description weren't far off.
For the most part, his admiring ogling was fairly wistful, most of what was on offer being either too expensive for his budget or too esoteric in function for him to justify the purchase. Nevertheless, he continued trawling the catalogues like a child drawing up his Christmas list, filling his daydreams with robots of every type.
Naturally in his searches he occasionally came across a machine he was especially prone to drooling over, filling his technophile heart with besotted want. His desire was generally tempered by the lack of money to fulfil it though, and it eventually faded. Today however, as he browsed through one of his favourite catalogues, one particular entry caught his eye. He called it up, and was astounded by what he saw...
"An experimental prototype, this model was deemed unsuitable for mass production due to reasons of materials and manufacturing costs, leading to cancellation of the project. To recoup production costs, we have elected to sell the prototype off at a discount, and so Mechtech, Inc. is proud to present MT-NS-01!"
Along with the explanatory text were a few photo of one of the most strikingly beautiful robots Mattias had ever seen: a tall and slender feline gynoid covered in smooth white fur, head crowned by long and lustrous blue hair, stern face highlighted by crimson lips and blue eye shadow. Her uniform consisted of a bikini, gloves, knee-high boots worn over thigh-high stockings and a tail-sheath - all made of polished red and black rubber.
Mattias stared at the gynoid in amazement, enraptured by her smooth, seamless form. After several seconds spent simply taking her form in, he shook himself and continued reading the advert.
"Despite her stern expression, MT-NS-01 is polite, friendly and diligent. She is ideal for security work and bodyguard duty, although she is adaptable and well-programmed enough to ably perform most any task she may be given. Please note that due to the experimental nature of the unit, MT-NS-01 may have certain hardware and/or software quirks that might cause unexpected behaviour during operation, but we are confident that this will not significantly affect performance."
Mattias skimmed over the rest of the entry, before turning his eyes back to the pictures of MT-NS-01. He had seen attractive robots before, but none that were quite so beautiful as her - nor indeed quite so desirable. He found himself consumed with want, obsessed with the fabricated feminine feline. Mentally setting himself up for disappointment, he checked the price... and was taken aback once again. The gynoid wasn't exactly cheap, but she was a damn sight less expensive than he had expected. She was even less expensive than many of the more basic robots in this particular catalogue.
Drumming his fingers on his mouse, Mattias thought hard. He didn't really need a robot of any kind, certainly not a security unit, and even as affordable as she were, his wallet would feel a purchase like this for a while. Still, even among the robots he wanted, this one was special. He had never been quite so taken with a machine, and he knew he would never get her out of his head. He knew he would always regret it if he passed this up.
However, as hard as the internal debate may have seemed, in truth it was already decided. After a few seconds of deliberation, Mattias hurried off to retrieve his wallet. He returned with it and frantically extracted a card, then called up the order page and entered the relevant information as fast as he could manage. Soon enough, the order was placed, and the confirmation email sat happily in his inbox.
Glancing back and forth between the confirmation and the promotional photos of his new purchase, Mattias couldn't help but giggle excitedly with anticipation, like a child seeing Christmas presents piled beneath the tree. He got the distinct feeling that his thoughts during the next month would be of a rather robotic bent...

---

Striding with whirring step, feet moving in sensuous mathematical arcs, servos working in mechanical harmony, processions of superbly-engineered fembots on electronic parade... Mattias' dreams of late had often been of the same gynoid-y theme, which didn't really help with his impatience. As much as he liked receiving packages, actually waiting for them to arrive was not nearly so fun. In any event, he thought blearily to himself as he got up, there wasn't a great deal he could do about it.
He spent most of the day as he usually did, attempting to distract himself from his anticipation with normal day-to-day mundanities. As so the day fell into his usual pattern, until lunchtime at least...
Shortly after he'd cleaned away his used flatware, there came a knock at the door. Trying not to become too excited, he got up and answered it. At the door was a deliveryman, looking rather exhausted.
"Hi, I've got a package for this address, but I think I might need your help getting it in. Would you mind?"
"Uh, no, that'd be fine," Mattias replied. He stepped outside to find a tall box, easily big enough to hold a good-sized person. Excited as he suddenly became, he did his best to keep it hidden from the deliveryman, as he carefully tipped the crate on one corner for them to manhandle it inside. After a few minutes of lifting and grunting, the box lay on the floor of Mattias' living room. The deliveryman wiped the sweat from his brow and handed Mattias his clipboard. Mattias quickly signed it, and the deliveryman bade him farewell and departed.
Now alone, Mattias could giggle excitedly all he wanted, which he did. In fact, it was all he could do not to start jumping up and down like a giddy schoolboy. He knelt down beside the box and looked it over. Aside from the Mechtech logo on the lid, the box was more-or-less plain, with the only features being the hinges on one side and the padlocked latch on the other. The key to the lock had been left in, so he unlocked and opened the box, before moving aside the upper layer of foam padding, revealing the crate's contents...
As much as Mattias had admired the pictures of the gynoid, he was still stunned to see her in the flesh, for lack of a better term, stretched out before him in the other half of the her-shaped foam padding, almost looking as though she were peacefully asleep. Her rubber clothing had been polished to an excellent sheen, positively gleaming in the afternoon light, in distinct contrast to her pale fur.
Mattias stared at her, thoroughly entranced. He knelt down next to her crate and looked up and down at her perfectly built form. Even this close there was nothing to suggest her artificial nature. He reached out a hand, hesitantly, to feel her arm. In contrast to her realistic exterior, under the unnaturally soft and smooth pile of her fur he could feel bundles of thin cables and the metal elements providing her with a skeleton.
While he gently probed the structure of her upper arm, Mattias almost failed to notice a soft hum permeating the gynoid, as her systems came to full power. However, he did notice her eyes open, revealing a pair of sharp yellow irises. In surprise, Mattias drew sharply away from her, standing up and watching as she gently sat up in her foam alcove, looking around and surveying the room. As her gaze fell upon Mattias, she stepped out of the crate and stood before him. She looked him over appraisingly with a stern expression, though this seemed to be due more to the design of her face than to any particular emotion or opinion.
"Please identify: you are Mattias Velinov?" she queried, in a pleasant mechanical-edged voice.
Still somewhat dumbstruck by the gynoid in front of him, Mattias nodded in response. "I... y-yes, I am," he answered after picking up his slack jaw.
She drew herself up to her full height and stood respectfully to attention.
"Then I present myself for service, master."
Mattias blushed and smiled nervously. "Umm... th-thank you, MT-NS-01..."
"What are your orders, master?" she asked.
"Well... why don't we sit down and talk about it?" Mattias suggested, settling on one side of the sofa. MT-NS-01 nodded and sat down next to him, still gazing attentively at him.
Mattias bit his lip, smiling nervously as he took in his new robot. "So, MT-N... actually, would you mind if we gave you a shorter name?"
The feline gynoid shook her head softly. "I would not mind at all, master. What name shall you give me?"
Mattias thought for a moment. "How about... Mittens? Is that alright?"
Mittens nodded. "Affirmative, master. Designation "Mittens" logged."
Mattias smiled. "Lovely! So... the website I got you from said you were an experimental unit?"
Mittens nodded. "Affirmative, master, although the project was never completed."
"What sort of experiment was it?"
"Original project specifications were to test a number of manufacturing and repair technologies, and to create a matched pair of partner-unit prototypes. Although the manufacturing technologies were deemed successful, the model in question was deemed too expensive for further production, and the project was terminated before completion."
Mattias shuffled a little. "So... what would you have been like had the project been completed?"
"I would have been much the same as I am now," Mittens replied. "However, an additional MT-NS unit would have been constructed along with me, to serve as a partner and companion, fulfilling my partnership programming."
Mattias's ears perked up a little at this. "A partner unit? What would she have been like?"
"She would have been built to the same specifications as me, master, so she would have been essentially identical to me. Why do you ask?"
Mattias shrugged, blushing a bit. "Well... it's just that... you're rather lovely and..." He trailed off, blushing more strongly.
Mittens tilted her head curiously. "You find me attractive, master?"
Still blushing furiously, Mattias nodded in affirmation.
"And you would like a second MT-NS unit, to serve as my partner?"
Mattias nodded once more.
"Very well, master."
As soon as she had said this, Mittens suddenly darted her hand under Mattias' shirt and pressed it against his stomach, gently but firmly. He yelped in surprise and tried to recoil from Mittens' hand, but she withdrew it first. He pulled up his shirt to see what she had done, but no damage or mark of any kind was evident, beyond the handprint in his fur.
"Wh... what was--?"
His protests were cut short, however, as a mark did indeed become evident: the handprint that Mittens' touch had left in his fur was lightening and turning white, the same white as Mittens' fur. He watched in wide-eyed shock as the whiteness spread across his belly, up towards his chest and down towards his crotch. But that wasn't the limit of the changes - as though an invisible corset were being tightened around it, his waist started to contract, narrowing down little by little.
Mittens stood up and calmly watched as Mattias' body reshaped itself. Where the border of the transformed area met his clothes, they either took on the glossy sheen of latex or simply vanished entirely, soon leaving Mattias with a bare midriff and red rubber panties over shapely hips and a pert behind.
As his legs became slender and stockinged and his increasingly feminine body filled out into an hourglass figure, Mattias stared in amazement, unable to voice any kind of protest and barely able to comprehend what was happening to him. It was not a painful experience thankfully, although where his fur was bleaching white he could feel a strange heavy sensation inside himself. If he had had the presence of mind to hazard a guess about it, he would have rightly assumed that his innards were converting as well, going from organic to mechanical, rendering themselves into the machinery that drove a robot such as Mittens. As it was however, most of his thoughts bounced between terrified and amazed... with the exception of a few new brainwaves that were ticking over in cool logical steps...

The wave of transformation started down Mattias' arms, his natural grey fur supplanted by the pervasive synthetic white fur. His own arms hadn't been especially thick, but under the effects of the conversion they shrank and became quite svelte, though their apparent delicateness belied their mechanical strength. As his fingers followed suit, they were soon covered in black rubber gloves, while at the same time his newly stockinged feet gently arched to accomodate the wedge heels of the knee-high boots forming over his long legs. Even his lazily curving tail was sealed in a long latex sheath.

Within a matter of seconds, the transformation had reached Mattias' neck, leaving his head sitting atop a tall, svelte body identical to Mittens' own, with similarly slender limbs and ample breasts, clad in an identical tight rubber outfit. But naturally, it didn't stop there - already Mattias could feel the skin of his cheeks tingling as the fur there turned white and synthetic, as well as the curious feeling of his newly blue hair lengthening, spilling over his now-narrow shoulders. His ears twitched reflexively as they too succumbed to his robo-feminisation, turning pale and shrinking slightly into a more delicate shape.

Although his chin had never been huge as a male, now it became positively petite as the transformation finally started to take hold on his face. His lips became plump and full, turning the rich crimson colour of freshly-applied lipstick. His eyes, still wide with shock, subtly reshaped themselves, rimmed with long eyelashes, coloured with soft green irises. His eyebrows, in turn, became soft delicate arches, and the space beneath them was filled with blue eye shadow, completing Mattias' new gynoid-styled make-up.

Still bewildered by his predicament, fearful questions continued to circulate in Mattias' mind... before they were suddenly overpowered and halted. His mind froze for an instant... and when it started up again it was a very different mind, on every conceivable level. Where once a chaotic carbon structure had played host to manifold biological impulses motivated primarily by base instinct, now electronic signals marched back and forth through a finely-engineered silicon machine with mathematical precision. All that now remained of Mattias was an archive of his memories, stored in a memory chip in the central processor of the entity that had replaced him piecemeal.

UNIT REASSEMBLY COMPLETE
The new gynoid's face fell into its default expression of stern alertness. She got up from her seat and stood to attention before Mittens. The two fembots gazed appraisingly at each other. There was almost no difference between the two besides their eyes - the original possessed golden yellow irises, in contrast with the new robot's green.
"Unit, state designation and provide status report," ordered Mittens.
"Unit designation is MT-NS-02. All systems functioning at optimal performance," her companion replied in an identical voice.
"Report success of conversion from organic stock," Mittens continued.
"Conversion was fully successful - unit "Mattias" has been completely reassembled into MT-NS-02."
Mittens stepped forward towards MT-NS-02, her arms gently encircling her new sister unit, lips turning up in a shy smile. "Identify level of gratitude for conversion?"
MT-NS-02 reciprocated Mittens' gentle embrace and softly smiled back at her. "Gratitude level is high, current form is mechanically and aesthetically optimal." She drew Mittens close to her body. "Additional... affection level is at maximum..."
The new gynoid fell silent, and gave her companion a kiss. Her full artificial lips met Mittens', and the two feline fembots shared a long, tender kiss, bodies pressed tightly against one another by tightly embracing arms.
It hadn't gone precisely as intended, but the project was complete - two robots partnered together, supporting and fulfilling each other's programming like good efficient counterparts...
