Prototech Nanite Development Facility
Biological Applications Branch
Column D6

The Nanite suit was a risky proposition from the get go. Loosely based on the EMP pressurized design of the basic isolation uniform worn by staff at the BAB, this variation was intended to alleviate the impediment of the original isolation suit and included a modular nanite collection attachment. We think that particular aspect of the design was what ultimately did the trick, but the end result was unexpected, least of all by head designer Naoki himself.

We think.

Naoki was having a hard time just staying focused because of the Nanite suit alone. He had made it to the outside edge of the contaminated zone. It looked like they had managed to evacuate most of the people here, which was ironic considering half of them weren't even authorized to be working on this particular nanite strain. The research lab was still brightly lit, the metallic surfaces humming with the constant surge of energy that flowed down the corridors of Column D6, where some of the more publicized advanced were being made in nanite applications. One of those applications itself coursed through Naoki's bloodstream; a top-tier nanite strain called Mercury that kept biological systems operating at peak efficiency. Naoki, himself, as a result, was a perfect specimen of his own race; sleek, slim physique taut with muscle that the Nanite suit highlighted almost obscenely. Which was how Nao had designed it. The static nano-polymer material shone with all the gloss of latex but adhered to the shape of his body like a second skin, a purplish-red color marking the extremities with white color covering the torso. All the ridges of his flat stomach, the swooping dip of his collarbone, and the uninhibited bulge of his crotch were on display. But the level of perfection allowed by the Mercury strain had almost eliminated any kind of need for modesty, since embarrassing physical imperfection was scoured away. Which was not to say that unique characteristics were absent from Naoki. 

For example, he had four arms.

He was short. His long ears hung down past his shoulders, ending in white tufts and his muzzle was white, a flared stripe of purple curving down to his jawline. Above that, his gold eyes, accentuated by black outlines lazily examined the door in front of him. One set of hands were placed on his hips, resting in contemplation while his other arms were crossed. He was making a decision, every inch of his body language screaming of indecision.

A moment away from breaching the epicenter of what appeared to be a relatively harmless contamination incident, Naoki hesitated. Running a gloved hand through his profuse hair of white, he let a brief impulse interfere with the pseudo-sentient Mercury inside him. Suddenly, his stable heartbeat began to pulse heavily, an experience that Mercury was designed to inhibit, as it proved distracting. But Naoki was nothing if not a purveyor of distractions. He himself had launched the initial design stage for Eros, the very strain of nanites he was investigating the outbreak of. The name alone was a dead giveaway for Eros purpose, but the programming phase that had only just begun was proving to be even more complex than originally intended. One of the built-in safeguards of the nanite was being designed, but the difficulty was in giving the proprietary AI the appropriate amount of sensitivity to the user's mental and physical state in correlation to their actual desires. Given the Eros strain's ability to drastically manipulate a user's chemical and biological reactions, the AI's processing capabilities had to be enhanced to compensate. Naoki considered that maybe it would've been wiser to dumb down the nanites abilities, but his philosophy was "over-design first, ask questions later". Which didn't fit so well with his hands-on design esthetic, but with a shrug and a grin, he threw what little caution he had to the wind and pushed the "open" stud on his security remote embedded in the suit's forearm panel. The door in front of him swoosh-ed dramatically. Another button and the eighteen circular ports embedded on the suit began glowing, signifying the the nanite collection module was starting up. A large, round pod that clung to Naoki's back was the central compressor for the nanite collector, and the sensation of suddenly becoming lighter alerting him to its powering up. The suit felt tighter, and the yellow glow of the collection ports beeped and turned green.

With a confident stride Naoki passed through the small doorway and into what appeared to be an expanded nanite monitoring suite. Most of the room was taken up by a large metal box from which hundreds of monitors and bunches of cables extended, picked up by three different computer nodes, consisting of banks of monitors. Naoki briefly and quickly eyed each one then made a beeline for the nearest. With a flick of his upper right arm, the whole matrix of screens lit up. With a fluid grace, Naoki's other appendages went into motion, lovingly stroking the touch screens as windows of data were summoned forth and security protocol bypassed multiple times by the heat signature of his fingerprint alone (for which the suit was designed to interrupt the surface temperature conditioner and admit forth automatically). Eventually, five of the visual feeds were hovering over a single user access script that seemingly lacked an on-screen context. While punching up a personal log file and twiddling the settings, Naoki began reciting the details of his investigation so far as he retrieved a small ident-gun from the shoulder satchel he carried. Pressing it to port on the collar around his neck and pulling the trigger, it extracted a minute bit of his being in a way that ensured that it was straight from the source and uncontaminated, matching perfectly his minute profile on record. Pressing the nose of the ident-gun into the appropriate slot, the screens blinked and Naoki saved the incomplete journal file to his personal network as the system spilled its most valuable secrets. Seconds later, Naoki had brought up another log file, the most recent one, and a voice was heard from the computer as it was activated, the identity of the creator confirmed as a member of the Eros research staff.

"The evacuation is being handled appropriately, and all the infected members are being quarantined immediately, myself included. However, I've managed to do some last minute research on my own and I'm hoping that while I'm in quarantine they'll let me continue to investigate this possibility, but I'm worried the Eros AI may eventually be able to subvert the Mercury super-protocols. I can't be sure unless I track the Eros behavior further, and if I alert the DeCon authorities they'll have us isolated, possibly permanently, in which case they'll never find a cure, so I'm keeping my mouth shut and crossing my fingers. At least I know that, even if Eros manages to integrate itself into the Mercury strain, it won't have any fatal consequences. DeCon agents are here-"

Naoki's heart was racing, and his eyes were wide as he sought out the details of the scientist's research, again using his ident-gun to access the information, the system demanding a second, more detailed bio-sample. The perfectly conditioned atmosphere and the aid of the Mercury nanites prevented Naoki from sweating the bullets he should've been as he traced the Eros development and realized that, if the research was accurate, the Eros nanites would be implementing their takeover any second now, meaning that, back at the local DeCon facilities, twenty  BAB agents would be undergoing some rather obscene and uncontrollable  changes. Naoki would have to start working on a cure, start engineering a reversal regimen that would restore the Mercury protocols. Thank god, he thought to himself as he starting a new project template, the Eros hadn't gotten into the system yet.

Then, the screens all locked up and turned a rosy, luscious pink. White block letters blinked onto their surfaces.

"Welcome to Eros," the virus said to him, and Naoki's eyes locked onto the ident-gun still in his lower left hand, where the confirmation chip had turned an unnatural pink, a digital smile manipd onto its surface.

"Fuck," Naoki spat, realizing that the nanites had snuck into the chamber of the ident-gun as soon as it had interfaced with the infected research CPU, and that the second security bypass had been a ruse to get him to plug the ident-gun back into his collar where the virus could be transmitted.

He could almost feel the Mercury nanites inside him being hustled by the smarter Eros carriers who passed along their corrupted programming like it was a trendy haircut. Naoki was reopening his network profile to get outside the quarantine and warn someone or request help when he felt his body heat rising and he knew the Mercury had succumbed completely. His hands started trembling, a completely foreign experience and he felt blood beginning to pulse into his crotch, unrestricted. Thoughts of his state and the possibilities that Eros might inflict on him made him hesitate to contact DeCon for help, at the last minute. If he alerted DeCon that he was infected, they would arrive just in time to see him fully altered by Eros, which would be followed by his immediate isolation and quarantine, and then someone else would attempt to access the research files to engineer a cure, and they would be infected, and then isolated, and the nanites would just keep spreading. Naoki couldn't alert anyone to his current situation because that would play into Eros hands. But what solution did he have?

The question pressed on Naoki as hard as the erection that was growing against the conformity of the suit he wore. The suit was designed to assume that the wearer would never experience any undue sexual stimulation, so no constriction was designed into the genital region. How far it would stretch, Naoki contemplated with a mixture of curiosity and worry. The warmth that was pulsing through him was a centralized heat, radiating from his crotch, and the very sight of his own engorged member made him that much hungrier. There was no point, he reassured himself, in fighting the Eros effects, and he could only hope that once he was satisfied, the changes would subside long enough for him to engineer a fix.

With a sigh of anguished relief, he leaned back against the pink-hued touch monitors and clutched himself, fondling his swelling testicles with one set of arms and gently caressing his growing cock with the other. If this was all the Eros had planned, then Naoki was disappointed in the AI's lack of imaginative programming.

With a hard gasp, Naoki felt his heartbeat split in half, and the rush of pleasure that rushed through him ebbed for a moment. It didn't take him long to figure out that the Mercury/Eros hybrid was creating a twin heart solely for the sake of keeping the sexual activity it provoked heavily fueled. It wasn't painful, but his chest had to expand to make room for the new organ, and that growth was an uncontrollable spasm, Naoki sucking in breaths of air and clutching his muscled chest, stroking his cock slightly, unconsciously with his other hands. But the expansion didn't stop there. 

As the second, newborn heart jump-started into action, Naoki's lungs seemed to take in more air than possible, and a ripple of power rocked Naoki. The compact line of his stomach became harder as he arched his back and his pecs visible thickened, the muscles of his torso doubling, a six pack bulging out as the same amplification spread to his legs and arms. His throbbing cock was aching with fullness as he flexed, biceps becoming fully-developed. As he relaxed into the changes, Naoki seized his ripe penis and stroked hard, the glossy smoothness of the isolation suit lubricating the action smoothly. 

Naoki was struggling to stand, braced against the computer behind him, his newly enhanced physique taut as a payload of orgasm pulsed inside his testicles. Stroking harder, he panted at the climaxing fullness of his erection, and as he slid to his knees, his balls grew against his thighs, the silky meeting and the slight pressure, stimulated him to the point where his penis shuddered and swelled impossibly, bulging against the suit, a slight tension of resistance eliciting a stuttered moan. Forced to spread his legs wider as he straddled his inflating sac, Naoki's head lulled back, ears dangling, and he caressed the furious head of his member, stroking it as it trembled with unspent ejaculation. With his bloated testicles weighting him down, Naoki proceeded to stroke himself with all this arms, whispering wordless pleasures to himself, a climax teasingly full inside his massive penis. Briefly hesitating before provoking himself further, Naoki leaned forward, his pale hair falling over his hollow eyes, burning gold. Reassuring himself that the end was just seconds away, Naoki took the head of his cock into his mouth and sucked on it as he stroked furiously, thrusting into the orgasm.

But as he came, the suit constricted around Naoki, and it squeezed the nanite-laced cum back into Naoki, whose testicles inflated, making Naoki whimper with frustrated need. His legs barely encompassed the girth of his bloated sac, and as he tried to get to his feet, he could hardly move. The all-encompassing desire to stroke himself even more was struggling with his urgent realization that the suit was doing exactly as it was designed; suppressing the spread of nanites. Naoki brushed the sensitive tip of his cock and the quake of stimulation launched him into another burst of self-pleasure, cupping the head as he stroked again and came. A torrent of ecstacy pushed through him and into his member, visibly expanding with the explosive ecstacy that marked his orgasm, making him arch back. But even as his penis roared, he could only stroke more, nothing escaping. Instead, as he stroked, the taut balloons of cum beneath him bloated further, and touched the floor. Even as more of it entered, Naoki thirsted even more for relief, anything to sate to the unending tension that filled every inch of him. But sucking himself again and causing an even more powerful climax tear through him caused a massive growth, until he was literally astride his own massive manhood, unable to stop himself, cumming again and again, growing to an immovable proportion, becoming nothing so much as an expanding feedback loop of ecstacy and growth.
