“Hey, check this out!” Jeff typed, sharing the link to the email that confirmed his greatest wish. It had been strange for such a big-name factory to post a tour contest on their ERP thread, more so perhaps because it was where they generally role-played adult scenarios of object transformation. Regardless, as a vehicle enthusiast, the chance to qualify for an exclusive tour was the best thing to happen to Jeff all year. And to his delight, the message he had been waiting for finally came to fruition. Their tour was scheduled for next week, and Jeff was excited to drop everything in his schedule to attend!
The factory was well known for its development of AI-powered vehicles, and it was one of the only companies able to successfully adapt the technology for commercial use. As such, their process was a closely guarded secret, not wanting it to get out to competitors. Yet, it seemed they were beginning to offer private tours for potential fans, something Jeff would kill for the chance to visit. Sure it was some sort of scam, Jeff had applied for the chance regardless, for him and his two friends. An engineer by trade, the fox man enjoyed tinkering on dirt bikes on the side, loving the draw of their design. He spent many weekends on his dirtbike, fueling his online fantasies of literally becoming one with his machine. Not that such was possible, of course, but the idea of AI-powered machines was the next best thing. That, and he could spend a lifetime in such a factory, wanting to learn all their secrets and designs!
“Congrats, dude! I should be able to make it!” Rick typed back, allowing the excitement to settle in. He had been hesitant, though part of him didn’t want to go if the three of them couldn’t be together. Waiting for a few minutes, he was delighted to read Robby’s reply, “I’m off from class that day if someone can pick me up!” to which Jeff smiled. Everything was going according to plan, it seemed!
As much as his friends were skeptical about the idea, there was no denying their own growing interest, especially since Jeff continued to hype it up. Rick, a cheetah, was a bike racer, something most people found odd for one of his birth. He could run far faster than most of his peers, of course, but there was something about the speed a bike could reach that surpassed any thrill he could get on foot. Part of his draw to their roleplay was his desire to be the bike, traveling at even greater speeds under his own power. Robby, while still in college, was a farm boy at heart, spending summers at home and pulling his own equine weight as well as using ATVs and other equipment for work. He wasn’t as mechanically inclined as his friends, though the idea of becoming an object was powerfully arousing. As such, he often used his farm machinery as the focus for his changes. His friends would tease him about his willingness to forgo his horse cock for the fantasy of being a machine, which left him to blush. Though he had to admit, the teasing wasn’t without merit!
Thankfully, the three of them lived close enough that they had gotten together on multiple occasions, though they saved their adult fun exclusively for online roleplays. It was still nice to be together again, especially for such an exclusive tour geared to their interests. Jeff was on cloud nine, unable to resist wagging his tail as they waited in the lobby for their tour guide to join them. To their surprise, the man to greet them was the company owner, Brad Kipling, a rather handsome middle-aged buck who came up to shake their hands. Jeff was nearly ready to keel over, trying his best not to stutter. It was like a dream come true for the CEO to be here in person!
“You’ve all signed the NDA, yes?” He asked, to which the trio nodded. It seemed standard enough, though after the first few pages, each stopped reading. The fact that they were allowed to visit at all was beyond their greatest wishes and was worth any fine print!
“Well, I bet you can’t wait to get started!” Brad exclaimed, clapping his hands together, before taking them through the main doors into a rather expansive factory. There were dozens of machines, stands, assembly lines, and other things that even Jeff had no words for. Everything was state of the art, and it was all Jeff had not to run from display to display, eager to be told how each worked. Jeff could only hope he was smart enough to understand it all! Rick, too, was rather enamored, and while Robby’s own degree hadn’t advanced to this point, he was still eager to glean what he could from the tour.
“I’m sure you’ve already read the papers on the capabilities of our smart vehicles. Able to drive on their own, fully autonomous in properly identifying and recognizing obstacles of all kinds. It’s just as capable of determining the difference between a flock of pigeons or someone running toward the vehicle and responding accordingly. An over 99% rate of success in all metrics, in the field and in the lab. True level six automation. And I’m sure you’re eager to hear our secret?” Brad asked, to which Jeff felt his heart skip a beat.
“Y-yeah, of course!” Jeff exclaimed, unable to keep the excitement from his voice. Surely, they wouldn’t be told the exact details, even if they had signed an NDA. Companies had been struggling with the development of such adaptable AI for over a decade. The edge this company had seemed to go well beyond all their competitors. To give it away so callously…
“It’s hard work and ingenuity!” The CEO laughed, to which the three felt themselves groan internally. Surely, it had been silly for them to think they would be told otherwise. Rick allowed himself to laugh at the silly joke, as did the others. It was a bad joke, though hardly any more than they could have expected. And yet…
“Well, that’s not entirely true. Nothing is more powerful than the brain, after all, and trying to make AI without it was simply a futile endeavor. Having the durability of a machine with the advantage of a brain, however…that was the breakthrough we were looking for!” Brad suddenly explained, as though it was the most normal thing in the world.
Jeff felt his ears twitch at that, unsure what to think. It was almost like the role plays they had done multiple times. Surely, he had misheard. Yet, as the three of them exchanged confused glances, it seemed they had perceived the same thing. Then, what did that mean?
Sensing their confusion, Brad continued with his explanation, having them as his captive audience. “It might seem like science fiction, though with that final puzzle piece in place, it was easy to calibrate our other secret weapon,” the CEO explained, making a grandiose gesture. “Fine-tuned self-replicating nanomachines have numerous medical applications, though the ability to change organic material into inorganic without side effects is just as impossible as the fictional Philosopher’s Stone. But a hybrid of such, well, that is the responsibility of the machines you see here!”
“We can’t simply remove or remake the brain, of course, but to change one’s body with their brain intact is within our power. The brain must be retained to operate the body, while the rest can be altered into a mechanical hybrid state. Given our state-of-the-art equipment, one can customize their vehicle type and any aesthetic markers they desire. Programmed directives can be inputted, of course, but the action of each smart vehicle is powered by the brain of those who have been converted. While they can’t be mass assembled, of course, the breakthrough is a rather significant leap forward, as you can imagine!”
“Of course, the process is entirely safe for those volunteers,” Brad ended, and the trio looked at each other as though they’d missed something. “We do prefer to use volunteers; the process wouldn’t take otherwise! You have to want to integrate with our technology, and the rest is simple. Altering one’s body to become mostly a machine, keeping your intelligence intact, and being able to drive as the machine oneself. An operator is optional, of course, but our products are self-driving. Volunteers, sorry. Having volunteers to experience the process firsthand has been paramount for our research. And, well, I must confess to having an ulterior motive for inviting you out here today,” he finished, leaving the three hanging with questioning stares.
“It takes some time to fully integrate a volunteer with our technology, but we have managed to streamline the process. If you agree to a trial run, we can have you ready to go within the afternoon. You’ll be compensated generously, of course, so long as you agree that all data is the right of the company to use,” Brad explained, as though such was an offer he often made. He had to be insane! But the certainty on his face made all three light up with some interest to see where the afternoon would go.
Jeff found his mind racing with a thousand questions, though at the forefront was whether such was even possible. It really was everything they had role-played come to life. Hell, it started to make a bizarre sort of sense that would be the reason they, specifically, were invited. But to actually undergo something in real life like he’d been so turned on to imagine? Could he do it? Yet, could he possibly say no to the option before him?
“This can’t be real…” Robby mumbled, echoing their sentiments. But something had already set in their minds that even if the man’s words were insane, all this setup was a little too much to be a mere coincidence.
“We would want some proof…” Jeff asked without answering the question. It was obvious Brad intended to make them an offer, and the more Jeff reflected on it, the more he was sure he would try. So long as it was reversible, right?
“Ah, so you’re interested? Don’t worry, I can assure you it’s perfectly safe and reversible. We are always looking for potential testers, and our metrics show you all might make good candidates. But a demonstration is in order, I think. Could one of you hold out your hand?” The CEO asked, and without missing a beat, Jeff did so. If only one of them had the opportunity…he didn’t want to be selfish, but he couldn’t quite stem his excitement in the heat of the moment!
Walking forward with his hand outstretched, Jeff was not expecting Brad to pull out a glass tube filled with a silvery liquid. Slowly, he poured it over Jeff’s hand, and Jeff braced himself, confused as to what might happen. Still, Jeff almost jumped as the warm liquid ran onto his paw. Part of him wanted to touch it, though an intense tingling gave him pause. Rather, he stared fascinated as the liquid covered his entire hand, seeming to sink painlessly into the skin and leaving him to wonder what the hell he had agreed to.
Within a minute or so, the tingling intensified, and all three stared intently, waiting with bated breath. Hoping it wouldn’t burn the skin or anything of the like, Jeff was shocked to feel his fur start to pull within, leaving it bare within moments. What remained was a light gray, as a painless crack resonated through his fingers. Stiffening against his will, the digits seemed to merge together, the gray ooze making it hard to see where the individual fingers lay. Jeff could perceive the bones, joints, and tendons within dissolving, leaving little but the solid material converted by the fluid. What he was starting to realize was a nanite cocktail, readily converting his skin into something inorganic!
As scared as Jeff felt he should have been, he could only stare with expectation. It really was the fulfillment of his fantasies playing over his hand. Heart racing, Jeff willed himself to work through the uncomfortable sensations, his hand curling against his will. A flush of arousal played through his body, Jeff no longer caring whose company he was in. It was the fulfillment of every fantasy, and there was no way he couldn’t enjoy it!
As all three watched in fascination, his hand continued to curl around to the other side of his wrists in a perfect circle. The inner structures had obviously been removed to allow such as the nanites spread a rubbery black material to fill in all the gaps. Indents in a pattern of tire tracks took shape, and while there was no way to spin his new appendage, Jeff was sure that could happen with further alterations to his arm. It was bizarre to think of allowing the process to continue, but having seen what was possible, there was no way he could stop! His tire-hand was small for the moment, but that likely wouldn’t remain the case for very long.
“No way, dude!” Rick exclaimed, unable to believe what he was seeing before his eyes. “What does it feel like?”
“Really numb…it doesn’t hurt but it’s strange as fuck!” Jeff managed to utter, mind awash in the sensations. It seemed the nanties were not inclined to spread past his mini wheel, though that reality left him eager for more. Surely, he would take the man up on whatever he offered next, regardless of the risk!
“It’s reversible, right?” Robby asked, unable to keep the fear from his voice. He had class the next day, and as much as his own member stirred from the possibility, it wouldn’t do for his ride to turn into a literal vehicle before he could be taken back to his dorm!
“I take it you approve? Such is only a demonstration, I assure you. Can I interest you in standing on one of our pads?” Brad offered, and it was all Jeff could do to stop his tail wagging.
Without further thought, Jeff followed the man as he was guided to the first of the conversion pads. Pausing for a moment, Jeff went to take off his shirt, not caring that he might need to strip down in front of his friends and a stranger. “Oh, there’s no need for that. The process breaks down your clothing for later use,” Brad explained as Jeff stood on the pad, waiting for what was to come.
Suddenly, a series of splash guards came up around him, isolating him from the rest. Even the fact that he could not escape was insufficient to deter his interest. Next, a series of hoses lowered from the top of the chamber, and Jeff was hit with a metallic, shaded spray. Much to his shock, his clothing started to melt away, sloughing off like wet paper. Soon, only remnant bits lay around him, and it took Jeff a few moments to realize their consistency had altered. It had to be the same nanite mixture that had changed his hand, only this time programmed to affect only his clothing, as the tilt of the floor opened into a collection bin.
“See? Nothing goes to waste! We will repurpose those for your exterior at the end of the process!” The CEO exclaimed, though Jeff didn’t know how he felt about that.
Rick and Robby could only look on with embarrassment for their friend as he was asked to go on all fours, the machine moving to scan him. His nudity was less of an issue, though it was his erection that had the other two feeling abashed. It was understandable, if not compromising, for Jeff to be in such a situation. All they could do was watch, the look on Jeff’s face a mix of fear and giddy excitement for what was to come.
A computer model of Jeff’s scan appeared before him, asking him to choose the details of his change. With his personal interests, it didn’t take him long to decide on an electric off-road bike. The computer was rapidly able to input his species, sex, and physical stats, as well as the necessary parameters to change, even coming up with his own model and reg number. The process was powerfully appealing, Jeff unable to slow down as he pressed the start button, happy with his selection.
With that, two panels opened behind him, from which crawled two additional hoses. On all fours as he was, Jeff was not expecting one to insert directly into his anus, pushing in rather easily despite his shock. While part of him wanted to squirm away from the discomfort, it seemed he was being held in place, the base of the hose inflating to form a seal of sorts. While he was confused for a moment, the other, tube-shaped head moved toward his penis, which was already out of its sheath. Despite himself, Jeff was unable to stifle a moan as it clamped down on the head, pumping warm air through it as the machine whirled to life. It was really happening!
“While I’m sure it looks uncomfortable, the infusion of nanite serum through such orifices is necessary, and some might say, a pleasurable part of the process,” Brad explained as the other two looked on with concern. “It will safely coat his organs, converting them to hybrid engine parts while keeping his body alive and well. This is, of course, necessary to attach the outer shell parts later on in the process.”
With that, the man entered something into a keypad, and a panel came up with what looked like an internal scan of Jeff’s anatomy. “This will allow you to view the progress. It should take about twenty minutes or so, and your facilities will remain aware so that you might enjoy the experience fully,” he explained as the other two slowly approached. Jeff had his eyes fixated on the screen, however, chomping at the bit for the chance to change. What would it feel like? Surely not every bit as arousing as he’d imagined. But if it didn’t, what would be the point?
Just then, the two pumps whirled to life, and Jeff felt cool fluid being pumped into his rectum. It was almost more than he could bear, filling him up and making him moan. Despite himself, Jeff felt his cock pounding further erect, allowing him to get through the discomfort. While the device seemed to be pushing its own nanite solution within his member, Jeff thought he had no chance of getting off. Yet, the steady increase in pressure, in tandem with his elation, allowed Jeff to feel the tension building nonetheless as the pump around his knot tightened its grip. It was all he could do not to whine, his elation over becoming the bike of his dreams causing him to orgasm. While he couldn’t properly ejaculate against the tide of nanite solution, he was adding a rather impressive amount of semen against the backwash. Panting, he looked over at his friends, the look of elation on his muzzle giving away his pleasure.
“Now that your friend is settled, can I interest you both in giving it a try? It would be best to get you started all at once in the interest of time. We have quite an efficient factory line,” the CEO grinned, and Rick and Robby gave each other nervous glances. Could they really go through with it? But since Jeff had already jumped in head first…
It did not take long for Rick to make his choice, moving toward the nearby pad. Jeff grunted, managing to ask him what he would choose over the discomfort of his organs shifting. It was a wonder he could still talk, though Jeff would have been happy to relinquish his voice temporarily. Still, he figured the choice was rather obvious, even as Rick answered, “A racing bike. Fuck, I can run but not that fast. It would be a dream to be that fast under my own power, you know? I’ve always wanted to…”
Rick’s voice trailed off as the splash guards went up and the fluids sprayed him down, his clothes falling apart and dissolving as Jeff’s had. They, too, were altered in composition, becoming metal and plastic as the hose coated his fur, leaving the cheetah to shiver. Having seen the same happen to Jeff, Rick got down on all fours, allowing himself to be scanned as he input the form of his own desire. It was all he could do to keep his body from vibrating as he chose the form of a gas-powered racing bike. Finally confirming his decision, Rick raised his tail, feeling the first of the hoses seeking his asshole. His own feline cock was rock hard by this point, the second hose clamping on it and nearly bringing him to orgasm right then and there.
Having looked on all the while, Robby felt sweat dripping off his body as his two friends were pumped full of transformative nanites. As much as he loved the idea of changing in fiction, the reality of such was too much! And that his friends had jumped in so willingly…Robby figured it was best for him to stay behind on the chance that they required his body intact.
Yet, it seemed that the CEO had other designs for him. “Now, why don’t you give it a try? Your friends are enjoying it, after all. Why would you deny yourself such pleasure?” He offered, and Robby felt his heart racing in fear. The insistence was more than alarming, and he found himself scared for his friends. And perhaps himself left alone in the factory and at the man’s whims.
“N-no, I’m good. I’ll just watch…” Robby replied, backing up as his tail swished over his pants in agitation. He was larger than the deer man, of course, but the CEO was in his domain, so to speak. All he could do was hope his fears weren’t justified, and the man was simply being insistent…
“Well, I can’t have you just sitting back. Perhaps some additional incentive is in order,” he replied, and before Robby had a chance to run, a blinding light caught his eyes from something descending from the ceiling. All at once, a series of rapid-fire images hit his brain, the technology something he didn’t understand but had no defense against, regardless. It was hard for him to really comprehend what he was looking at, though machines, bikes, cars, and a variety of things his brain found appealing seemed to rapidly pass before him. Such caused a stirring in his loins, given his love of transformation and prompting him to relive all the role-plays he and his friends had enjoyed. Those scenes played out before him, and despite efforts to resist, Robby found himself falling into the fantasy. The arousal flushing his loins could not be denied, and the mental images assured him that getting onto his own pad for conversion was the only way to satisfy those lusts!
Allowing himself to get sprayed and his clothes to slough off and alter their composition, Robby didn’t realize he was nude and erect until his horsey asshole was probed by a pump. Not having as clear a mental image of his own changes, Robby’s lusty haze had settled on a bike his parents could use back home. Their aging ATV could use replacement, and Robby couldn’t deny how sexually fulfilling it would be to fill that role. Despite his shame, a heady moan escaped his rubbery lips as his tail raised further and the pump shoved its way up his plump pucker. While it was pleasant against his prostate, it was the feeling of the grip on his horse cock that really did it for him, a bestial cry of pleasure escaping his lips. Any previous fears were erased by this point, Robby only wanting to be filled and changed. And to experience all the sexual euphoria he had always imagined would come from such a process!
“There, that’s a good start! I take it you’re all ready for the next step?” The CEO asked, and Jeff managed to nod his approval. The fluids had already made their way through his system, creating a cooling sensation as though his organs were being gripped by ice. It was hard to tell which organs would convert to which parts, though the sifting of the icons on the screen filled Jeff with excitement. He wanted nothing more than for his innards to alter into a series of tubes and engine parts, to allow for the rest of the changes to take place.
Still, it couldn’t quite stifle his nervousness as a series of dozens more injectors crawled down from the ceiling. Soon, they began sticking needles into the joints and muscles of his limbs and shoulders. It was somewhat uncomfortable, leaving him stiff as the muscles were converted into metal and plastic to connect to the altered organs within him. As much as he wanted to focus on the changes, the hoses from before rose from the floor, this time spraying more of the thick, silvery goop over his remaining paw and his feet. Even having undergone the same procedure before, it was still bizarre to perceive the digits fusing, the fur melting away, and the remaining rubbery skin forced to form a circular wheel. He wanted to put both out in front of him, though it was harder to move his shoulders and arms, given the conversion of tissue within. He could at least look down to see them, cock pulsating as his testicles shot another load against the tide of fluids being pumped through it. Lost in the changes, Jeff was ignorant of the next spray of black rubbery coating, something he figured was to seal his outer shell from the elements, as nothing of his fur was left to remain, save for on his tail and head.
As his other hand finished its conversion, Jeff was left to watch his fox fur fading into the skin before his shoulders collapsed into a straight bar. His legs followed suit, stiffening to form a thin metal S as the joints in his limbs reoriented to become his internal suspension system. Eventually, his arms folded in on themselves, legs bending down in an initial suspension test. As though judging the resistance to be satisfactory, the pressure relented, Jeff feeling an odd sort of pride at that. It was exciting to know the process was going smoothly, bringing him one step closer to the body of his dreams.
Startled, Jeff let out a yelp, feeling his pad suddenly moving on a track as he was taken toward another station. It made sense, given the scope of the factory, that he would need to be transferred. As he was put into position, two more firm tubes came from the padded floor, this time with intense heat. Jeff prepared himself for the pain, though he felt nothing as his mechanical skin was superheated. With barely any sensation, Jeff’s external suspensions were welded on, taking the spot of his former elbow joints and upper legs. Once more, intense pressure was applied in an effort to simulate the jumps his new form might experience on a dirt path. Seemingly satisfactory, what seemed like a brake assembly was produced via 3D printing, and applied to his front and back loops while large spiked wheels were slipped in with the axle.
“Oh fuck, it’s happening! I’m getting my wheels!” Rick shouted as his own paws were coated with the silvery nanite solution. It was alarming to feel his padded fingers and short claws fusing together, forming loops like what had happened with Jeff before. He was soon distracted by the injection of a series of muscle relaxants, similarly converting his tissues. Arms and legs bent into new shapes before his own suspension system was applied, albeit not as extreme as Jeff’s. Being sprayed down was alarming, given that his former skin was left to fuse with the altered mechanical organs within. Still, having his spotted fur erased for the development of chrome and steel was welcome, given it was a step on the way to becoming the bike of his dreams. And he was well aware his own application of a brake system would befit the street bike he wanted to become.
Robby, on the other hand, was receiving a similar treatment to possess something akin to Jeff’s own internally constructed suspension system. Rather than be coated directly with silver nanite solution, a drill was first used to puncture his hooves on either side. Soon, the nanite solution was applied, forcing them to expand into a pair of rounded loops. A brief gurgling in his guts soon passed as his internal organs were repurposed to the mechanical parts he would require for his new form. A pair of nozzles sprayed away his horse’s fur before the injectors stimulated his muscles to force his limbs to an even length. While he no longer had a pelvis or anything of the sort, he would be stuck on all fours, held with evenly spaced axle holders. A set of mechanical claws lifted up the former horse so that his external suspension springs, axles, brakes, and dirt wheels could all be gradually applied. As best he understood through the display in front of him, his new body would possess four-wheel drive and independent braking.
Given the intensity of their changes, each soon-to-be AI vehicle was given a moment’s reprieve, loving how their fur had been shed for a chrome exterior. If they still possessed hearts, they would be beating in elation for what was to come. Having their external parts applied was uncomfortable, though in truth was something they had fantasized about many times. It was soon to become more intense for Jeff as a surge of electricity was pumped through his penis before it was altered into a charge plug with the battery his former organs had created. His testicles, meanwhile, were to become the switch for the zip line to be put in lock or not. While the sensitivity of his orgasm should have evaporated, it seemed his pleasure was still present, the stimulation more than he could bear. And only to get better as he anticipated the next changes to come!
The fluids entering Rick’s cock were soon to transfigure it into a cold, hard oil intake, the switch connecting from the cat man’s former testicles. He didn’t seem to mind, regardless of the lack of flexibility it possessed. In some ways, it was like having a permanent boner, the stimulation not ebbing regardless of how the changes progressed. Robby’s horse cock had perhaps the strangest transition of all, becoming fully erect and soon linking the front and back axles to become his drive shaft. Swaying horse testicles soon stiffened, flattening out to become square-shaped for the basis of his auto gearbox. As much as it should have been alarming to lose their maleness, it was only another cog in the wheel, so to speak. Each former man, willing or not, could do naught but eagerly await the next step of the process.
Each in turn felt their pads being lifted up toward the ceiling, where an assembly had printed out each metal vest to be applied to their chest and backs. Coated with the same silvery nanite gel, each was connected gently, slotted for connection with a motor, mount points, and screw points. While the metal arms held them stationary, nanite gel merged through their mechanical skin to reshape the forms of their torsos. As their respective vests began to tighten around Jeff and Rick, each could perceive their torsos twisting to become the perfect fit. While their own forms became narrow and slim, befitting the bikes they were becoming, Robby’s already broad back had flattened out to allow his new frame proper attachment. None of the process was painful, rather almost sensual as the nanites reconfigured their bodies to connect with the newly applied parts.
Being moved along, Jeff yipped his excitement, voice more mechanical yet still present. It was obvious the next platform was to attach his electric motor, placed below his former chest, as tubes and hoses hooked up along its length. While the nanite plug in his anus had been removed already, a new plug had been formed in its place for his charger. The core battery itself was installed under his hips, as mounts along his former back were placed for the seat, side panels, and wheel guards. While he could no longer wag his fluffy fox tail, Jeff could perceive it being sprayed down with a nanite gel, remolded like clay, sitting over his former ass to become a storage bin. To his enjoyment, one fitted with a fox tail patterned decal!
Rick’s fate was to be fitted with a heavier frame and engine, befitting the racing bike he desired to become. His skin was more properly steel in contrast to the lighter alloys that had become of Jeff’s skin. Similar mounts were applied to his back, though additional paneling was placed for his engine block, and a seat cover that could be folded up or down. While uncomfortable, he still felt some elation to have his former anus repurposed as his muffler, as flashers and a license plate were installed under the pipe. Part of him might have wondered the purpose of that, given he was only to be a bike for the rest of the day. Still, he had little time for concern as his tail was raised high. A roller coated in nanites ran over the length, leaving only enough material for a long, thin antenna. Finally, a hole was drilled in the former cheetah’s lower back, ribbed for a fuel cap to be placed. Rick desired the ability to pant from the perceived heat, though his chest was held in place now, unable to rise or fall even if his organs hadn’t already been converted.
Robby’s process required mounts for an engine similar to Rick’s, both being gas-powered vehicles. The sensation of his horse’s tail being sprayed made him wish to raise it, though he was no longer able. It was regrettable that his tail was removed entirely, its dock drilled with a hole for his own license plate. His former horse pucker was mounted with a muffler, and a further hole was drilled on the side of his body, connected with his gas tank to be used for fueling.
“Fuck…does anyone else feel empty?” Rick asked aloud in a more mechanical tone as the alterations to their bodies came to conclusion. Each could still talk, albeit barely, their platforms close enough that their voices could be heard across the assembly room. It was strange to perceive any emptiness through the numbness their mechanical parts provided, but there was no denying that truth. The cap had already been removed from his recently formed gas tank, making the strange desire to be filled all the more insistent.
“Yeah, I kinda feel…weak, I guess?” Jeff commented, not sure what he meant. Robby, too, muttered his discontent, used to eating more, being a horse, and feeling powerfully empty with some frustration. How was he supposed to feel full like this?!
“That’s part of the AI integration. You have enough bodily awareness to know when you require refueling. Here, I think you’re changed enough to accept gasoline,” the CEO remarked, pushing some buttons on his pad. With that, a new series of hoses came out of the floor, this time inserted into their new tanks. “Oh fuck, that’s the good stuff!” Robby called out, feeling cool gas splashing against his insides. If he still could, Rick would have wriggled with excitement as his own tank was filled, a sense of fulfilment working through his form. Other hoses soon worked their way into the caps on their necks, filling them with the required coolants and hydraulics. As much as such would have killed their organic beings, the two moaned out their bliss, pleasure unhinged even without their mammalian genitals being stimulated.
Unlike the others, Jeff’s internal systems had been reconfigured into a battery, one with an external plug that was soon inserted with a charging cable. Body buzzing, Jeff could perceive an electrical charge flowing through him, the battery absorbing the energy and storing it to power his new body. Even without his penis or prostate, the pleasure was more than he could have expected. Hell, it was even better than the orgasms he had gotten from all those online sessions! The true rapture of being charged surpassed his expectations, electrical tingling ran through his being until his battery was at 100%.
***
“Almost finished! If you have any additional preferences for your outer shells or gear, now is the time to input them!” The CEO declared, his enthusiasm was not lost throughout the changes. Had they any ability for complex thought, each might have been concerned with his interest, or noticed the bulge in his pants. But as happy as they were to be filled and powered, there was no ability to look beyond the now. All three wanted only to change and discover their new abilities to operate under their own power.
Thinking for a moment, Jeff tilted his stiff neck, concentrating on the machine as the screen brought up a variety of packages. The myriad of options raced in front of his eyes, as though the nanites were connected with his mind as much as his body. Soon, the monitor constructed images of his soon-to-be body paired with fur tones to match his former fox coat. Some of the reddish tones turned to flame decals, and to top off the look, strings of cargo netting fell to be placed along his sides.
As much of a fan as he was of his cheetah patterns, Rick was quick to select a similar style for his own overcoat. Wanting a more regal appearance, he was inclined to choose the thicker black accents of a King cheetah. As best he could with his thicker neck, he turned around, nodding his approval over the pattern. For Robby’s part, his former brown fur didn’t feel fitting for an ATV, so reflecting on his family’s ride, he eventually settled on a lime green all over with the usual make and model insignia.
By this point, their paneling and dirt guards were being bolted in, and sprayers worked to touch up the paint. As strange as it was to feel largely immobile while the process worked its way through them, there was no denying how impressive it was to be changed. The whole process was still somewhat arousing, even though they lacked their former genitalia. But nothing so far could prepare them for the final stage, as a set of mouth plugs that appeared suspiciously like dildos was lowered before them.
“Are you ready to proceed?” Brad asked, and Jeff nodded, saying, “Here goes nothing.”
With that, he reached out with his muzzle, wrapping it around the phallic nozzle in an attempt to deep-throat it. Much to his chagrin, he was rather disturbed by the texture and taste of nanite goo being injected. It mattered little as soon as his ability to taste was removed from him, and the goo moved through his throat to integrate with the altered systems of his former body. The numbing sensation was far more intense throughout his head, and Jeff couldn’t shake the discomfort of his mouth and neck shifting. Pointed teeth shrank away into metal gums, and what remained of his tongue fused to the base. A flattened snout pushed against his eyes before they were widened with new space, rounded into bulbs that would be his headlights. Somehow, even though his eyes were functionless, he could still see, a visor forming from his former forehead as part of a HUB display.
The sensation of his ears being pulled back was a little alarming, though it was fulfilling to feel them widen into what would be his mirror holders. Glass formed to reflect his friends behind him, the ear holes fitted with handles to place mirrors in. Jeff could no longer wince as brass was painlessly placed into his neck for control of the Y axle for it to turn. Fur fell from his scalp as the back of his skull reshaped into a mount for the windshield. Lower down, a slot was installed for his dashboard, displaying his various gauges and apps on a waterproof screen. As best he could tell, his new brain would be wired for GPS and could connect with local wifi, something more modern than the usual bikes he rode.
All the while, Jeff was aware his brain was being infused with nanites as well, reforging the organic grey matter to a gray metal with a slot for additional programs. All Jeff perceived was a slight moment of memory lapse as the nanites worked into every valley of his mind. Every memory, every bit that made up Jeff the fox was still present, though in digital form now, as Jeff felt himself blink back into existence. Everything felt right and natural, and Jeff only desired more as the final changes were put in place to make him a machine.
With some curiosity, Jeff tried to speak, lacking vocal cords but figuring such was still possible. “This feels amazing!” A mechanical voice came from the speaker on his back. He was clean and polished from the nanite’s care, a full-on brand new dirt bike to the amazement of his friends.
Watching the same happen to Jeff, Rick was eager to wrap his own blunt muzzle around the dildo-shaped plug, filled with nanite goo that numbed and altered his insides. Soon, his snout became flattened, head remolded toward an oval shape. Eyes watered before they shrank, becoming small rectangles. Soon, his mouth became stuck forever in an O-shaped slot, and a HUD visor moved to cover his head. Feline ears were converted to mounts for his windshield, while ear canals were reconfigured to place the handles. A similar panel for a screen board was inserted behind his neck, possessing the circuitry in tandem with his internal wiring for the latest in wireless connectivity. Given the more urban range of his usage, his touch screen was prepared with additional options, though as his brain came back online, he was only excited about what he would be able to achieve.
“Fuck…can’t wait to race…” Came his mechanical voice as the nanites worked to wax and clean his outer shell to a sheen. While none of them were aware of it, the nanite package allowed their outer shell to self-repair to a degree even beyond biological organisms. They were truly the perfect self-sufficient machines, the pinnacle of modern technology. All while retaining almost total control of themselves and their usage!
While Robby was still the most hesitant of the three, he was still excited to wrap his horsey muzzle around the massive phallic nozzle as his own face was injected with nanite goo. Losing his teeth and gums was alarming, though he was still eager to experience his massive muzzle flattening to match the contours of his altered frame. Unlike the other two, his own eyes were pushed further together, changing his wider range of vision into a singular, strong headlight. It was bizarre, even as his brain was remodeled, that his visual acuity was superior to his horse senses. They were instead set in front of him, yet somehow, he was more aware of the world around him. Pointed horse ears were remodeled into the mounts for his handlebars and windshield, and like the others, the nanite tube was removed to leave his mouth set in an O shape. Feeling the nanites cleaning and polishing his outer coat was sublime, even superior to having his fur brushed as a horse.
“I can’t wait to work!” Robby called out, his previous concern lost in the elation of being changed. He was large, powerful, frame eager to pull as much or more than his equine strength. And needing only gas instead of food and time to digest it, he could go all day without fatigue or hesitation. A true fulfillment for the hardworking horse, something school and career could never provide!
“Fuck, I’m full and ready!” Rick called out, the words literal as he revved his engines. He couldn’t move on the pad as he was, but as the changes cemented, all he could imagine was the freedom to race on whatever track they had provided. It was nothing compared to the thrill of an actual race, of course, but for the time being, he could imagine it as he tested the abilities of his new frame.
Jeff simply revved his engine, likewise hoping there was a more off-road track for him to travel. As though his thoughts were connecting to his systems, Jeff became aware of the ability to turn on his headlights, their glow illuminating the chamber. As he tested his blinkers, he could see the others doing the same, experimenting with all the features they possessed. Rick was delighted to discover his seat warmer worked, though he was unable to feel the heat. Robby was testing his toe hook release and lock, all three exclaiming loudly their delight over the systems they had been installed with.
As excited as they were to go, Brad’s next words were a bit disappointing. “Now, due to some recent bugs in the systems, we have some software locks in place for your own safety. You’ll be able to undo the lock once the system checks are in place, but we will require a temporary memory cache before you’re clear to drive. We have a training course that can be administered subconsciously for you to enjoy, and before you know it, you’ll be ready to go!”
None of the newly transformed vehicles had any complaints as they were moved to motion-nulling tracks, and screens were lowered within their full point of view. It was a little alarming to feel something unexpected placed within their mouth plugs. Brains were hit with an electrical jolt as they were hardwired with a data upload, sending their systems into shock. It was enough that they didn’t notice their screens turning on until they sparked into a series of spirals, rapidly changing colors before their altered minds could keep up. And with the uploaded data still being processed, all three felt their thoughts becoming fuzzy, drifting to the pleasure of the changes and the desire to explore them…
All the while, their engines revved, feeling their wheels turning on the ground as they experienced an intense desire to drive under their own power. It was all they could focus on as the upload overwhelmed their senses, making any hesitation about their forms moot. Lost in the sensations, all notions of turning back at the end of the day began to evaporate in their minds. While Jeff was slowly beginning to understand that, nothing his mind could dredge up brought any despair. He had always wanted to exist only as a vehicle, right? He never wanted to go back…and even being lied to about it being only for a day was not enough of a deterrent. Especially if each day felt as amazing as this did…
Rick and Robby were dealing with similar thoughts as the words appeared in their HUD. New operating systems were being installed, though without the usual resistance that other ‘volunteers’ had experienced. It was easy to give up their wants to return to their former bodies when a part of them deep down had always imagined experiencing such. The hypnotic drone of images with racing, pulling, and operating without drivers was everything they had ever wanted and more. All they could do was wait for the program to upload and their lives to begin in earnest…
The sound of footsteps sent a smile across the CEO’s face as one of his chief designers came to do the final checks. “They are in perfect order, sir. The programmed conditioning took much faster than our initial trials. Collecting ‘volunteers’ from fetish sites was a stroke of genius, sir,” he remarked, with a hint of fear in his voice. Not that his boss would ever order him to undergo something against his will. While he was useful, at least…
“Yes, having our ‘smart’ vehicles consent to become permanent property is easy this way. Of course, they won’t want to turn back after our process. But I have a suspicion that perhaps they might have wanted it that way even without our influence…”
Afterward, the three vehicles were wheeled off to storage, their programs able to be remotely shut down. It didn’t matter to the consciousness inside, sleeping and waking only when they were required. While they were barely aware of it, they were eventually taken to a private show, displayed for rich investors eager to purchase the prototypes. They had no way of knowing the technology would likely never be mass-produced, though such exclusivity was sure to drive up the price. Every comment they made was a hint for future projects, prompting Brad to plan all the ways to use his newfound success with willing participants.
It was sometime later that each new vehicle rebooted, finding themselves situated on their ideal tracks. Jeff came to find himself at the head of a dirt road, a series of mounds and hills set up for a derby race. He was alone for the moment, but the exhilaration to try himself out went well beyond his ability to care. With speed and agility unknown to his fox self, he took off, able to race and even flip under his own volition. While he couldn’t shake the desire to have a rider, there was something powerfully fulfilling to drive under his own power. No thoughts of returning to his vulpine body remained; rather, Jeff simply looked forward to his first race…
Rick had come to some time later in a more urbanized track, elated to test his body in earnest. At the moment, he was in a street race, dodging traffic on the freeway with a speed that defied even his cheetah self. It was powerfully exhilarating to do so under his own power, not requiring a rider to race, and likely to become a real crowd pleaser as a fully AI bike. That provided him with a certainty that if he was offered the chance to change back, he would refuse. The fact he had not been offered one yet was of no concern, so long as his new owner allowed him the chance to race as often as he desired…
Robby, for his part, was bought by a private owner for a farm operation, waking up with some commands to perform a workload. It was a dream for him to be hitched up, pulling logs, refuse, and wagons through dirt roads and forest paths. The dirt and grime of his job were hardly a deterrent to his enjoyment, his outer shell cleaned often as his nanite fluids fixed any wear and tear. Perhaps more fulfilling was the programming installed that made him believe he was working for his family, instead. Not that his parents could ever afford a smart ATV such as him. But it was easy for his new owners to supply the hypnotic programming. Work horse he was, Robby was pleased to spend his time hulling for them, ignorant of the desire to return to his horse body or school. And the satisfaction of being forever useful, in tandem with the pleasure of being regularly filled with gas and cleaned, was enough to keep him content for years to come…
