Admittedly, having size controllers installed along with synthetic silicone dispensers was probably the best idea the two units had, even if they rarely got to use them in their everyday existence. It was the sort of thing that had limited application, yet when the opportunity arose, more than paid off for its initial investment in the sheer amount of enjoyment one could derive from it, especially when the controls were pushed to the limit and one’s physical form was turned into something best suited for a horny fever dream. For Chi and Gamma, this was precisely why they decided they were going to take the day off from their usual routine of moving boxes from side to side, in order to better focus on exploring as-of-yet untouched aspects of their relationship. As synths, it was seen as uncommon for the two of them to be together at all, let alone be as sexually active as they were; most of their kind veered towards the lack of any overt drive, preferring to engage in their chosen profession or hobbies as a means of activating their analogue for a “reward” system. The two artificial lizards, however, were significantly more concerned with maximizing their pleasure receptors’ functionality than they were in creating puzzles or folding proteins, hence why they’d gone to great lengths to modify their forms such that they could get the best out of them. They found it fascinating how biological units could derive pleasure from bodies that took quite a bit more work to change the shape of; the two of them at least could just press a button and make themselves larger, smaller, more or less rounded on a whim, but for the flesh bags, they needed entire surgical operations or dangerous genetic modifications. It made them feel blessed, at least as far as a synthetic being could, for their very synthetic nature to begin with; not constrained by the limitations of the flesh, the two could afford to experiment wildly with how far they could take their forms, to the point that, on occasion, they would end up being too big to move properly. Even when in their “normal” states, they were markedly different from those others around them; Gamma and Chi had sculpted themselves to near-perfection, at least in their eyes, and thus not only were adorned with the finest of hourglass figures, but added a decently-sized package between their legs to the wide hips, thick thighs, and torso-covering bust. It made it impossible for onlookers not to turn and face them on the street whenever they walked by, doubly so since the synths made sure to wear clothes that were as revealing as possible while still remaining on the right side of the law: provocative? Absolutely. Still legal? Also absolutely, no matter what prudes and busybodies wanted to claim. Still, there was something else to it that couldn’t be captured in mere size and curves, a certain fundamental truth that, while hinted at by their exaggerated forms, was still well-hidden enough that few would be able to discern it. After all, it was easy to dismiss everything the two synths did as just basic horny energy-fueled escapades and nothing more, not that different from the sort of thing that regular organics did, albeit with a higher degree of malleability and flexibility. It was easy to look at them and assume they were just doing it for the exhibitionism, that their outward attempts at making others notice their curves and sizes were just that: attempts at being noticed, and nothing more. In truth, this was a state of affairs that both Gamma and Chi worked overtime to maintain, seeing as it was simpler on them if they could convince others that they were just lovable sex maniacs than it was to get the true message into their heads… mostly because said message was deeply personal and not meant to be shared between anyone but themselves and those they trusted the most. Ultimately, all the growth and self-bodymodding weren’t just there for the kicks (though they were certainly a bonus), but rather as a form of mutual exploration and adoration; they weren’t growing just to grow, they were doing so because it helped them understand one another on a deeper level, one that most people wouldn’t be able to understand, nor would indeed believe should they be told. How could size-based kink play ever lead to a deeper connection with someone, when, by definition, it existed purely so those who engaged in it could live out a physical fantasy? Certainly, it couldn’t possibly lead to the sort of discoveries that would turn an already fulfilling relationship into a more loving and respectful once, certainly not when said size play was so loud and obvious and in everyone’s faces; and, to Chi and Gamma’s credit, they did a fantastic job at making everyone think that was the case, though in all fairness, given how loud they were, it wasn’t exactly difficult. But in the end, when all the stacked layers of bullshit were torn apart to expose the core of it, the main reason why they did what they did was because it led to a better understanding of who one another was, and that in itself led to a far better experience overall. It was about knowing one another on a level that no one else did, and the fact that it was done via kink play was, frankly, nothing more than a bonus. At the end of the day, however, they were still a couple of deviants who were more than interested in testing their limits to see how far they could go before their bodies began pushing back; that they hadn’t yet was only more evidence that they had a long way to go before reaching anything resembling a limit or a line they wouldn’t cross, and it was for exactly this reason that the two had arranged for what they were preparing at that exact moment. It had been some time in the making, mostly due to the difficult in finding enough silicone supplies and a size controller that had no cap installed in it; most commercially available girth moderators had an unfortunate tendency to have limitations built into their system, in order to prevent “abuse” by overly-excited synths. While these caps were usually high enough that most who used the devices wouldn’t have to worry, Gamma and Chi were not “most”, nor were they interested in being held back by people who they had never met before in their lives. They wanted to grow, and above all, they wanted to do so in a way that would let them finally know the full extent of both their bodies’ capabilities, and the arousal levels of their partner. It was all well and good to talk about how they would totally grow bigger than everything when they weren’t actually capable of doing so, but with an uncapped size controller, it was time for the two of them to put their money where their mouth was and actually do something about the rampant and near-uncontrollable size fantasies the couple was afflicted by. Chi in particular, being the largest of the two, was especially excited for their near-future prospects; the liz had made sure to plump their body up as far as it could technically go without them having to spend a considerable amount of money on an entirely new wardrobe, and even then she was pushing it with how fat she made her tits and how heavy her nuts were. Gamma at least was still relatively modest enough that he could pass among other hypers, even if he was encroaching upon territory that most people wouldn’t be able to reach without gene treatments or a very lucky lineage. The plan itself was simple: they would install silicone replicators in their external access ports, link them up to a couple of matter tanks they had purchased, and then… well, then they would late fate take the wheel. So long as they had mass to work with, the machinery could create silicone to inject into their bodies, and so long as the size controllers were functional, all the two really needed was the willpower and motivation to use them. And with a meeting coming up in about two hours, they had all the reasoning they could possibly need to go completely crazy; after all, what better motivator could there be than the notion of bursting out of their clothes while in the middle of a stuffy bunch of old crusty executives who probably hadn’t seen a boob for several decades, let alone touched one? Sure, it’d most likely tank the prospects of their project ever getting off the ground, but since when had they ever let that get in the way? Since when did they care about doing things the easy way? All they wanted was to feel the pressure rising as their forms were filled further and out, and from the moment they first touched the controllers to begin adjusting their relative breast size, they knew it was going to be one hell of a day. It was easier still than it used to be, which was saying something given how monumentally simple changing their was even in the worse of times. A simple flip of a switch and the inputting of a number, and both their sets of tits began swelling outwards, taking up even more space on their chests, and making it downright impossible to wear anything without causing serious clothing damage. Indeed, the two synths actually stopped what they were doing just so they could put some clothes on, purely for the experience of outgrowing it; once the button-up shirts were in place, it was right back to pumping their breasts up with even more mass, resulting first in them filling out the formal wear, then pushing against the buttons themselves, before copious amounts of synthflesh began bulging out from between the holes, straining the poor things holding both sides of the shirt together as an increasingly large amount of soft tit insisted on spilling out from within, threatening the structural integrity of the whole piece. It only stopped once Chi, thinking ahead for once, pointed out that if they kept themselves just shy from actually bursting out of their clothes, then there was a good chance they could do so during the meeting, thus making an even bigger splash! Sure, they were already carrying busts so large that they were practically turning their shirts into tube tops, but since when did they care about that? Better that they find themselves in the right position to make the best out of any scenario rather than blow their load all at once… though that certainly didn’t stop them from making readjustments to the rest of their bodies in the process. The most important aspect, however, was that they weren’t doing it to themselves; while they were getting busy being giddy over bigger sizes, the fact of the matter was that Chi was holding Gamma’s size controller and vice-versa, giving one another near-complete control over their mate’s form and heft. It was a trust exercise as much as it was an excuse to slut it up with immense sizes, and both synths took it to mean exactly that, hence, why the prospect of a meeting didn’t stop them from adding more to the rest of them. Yes, their tits were already big enough that, were they to be fully unleashed, they would cover most of their fronts down to the waist and manage to spill out a good couple of feet on both sides of their torso, but those were just their breasts. They could make their ass be that big, they could fatten their thighs up so much that they could not only compete, but outperform the cheeks they were supporting, and they could absolutely make their cocks and nuts be so ridiculously meaty that one had to wonder how they managed to keep their cool when their bodies were clearly designed to make them overload on pleasure at every waking moment. It was their secret: they were always horny; they just knew how to mask it well enough that they could “pass” for regular, sane people most of the day. Except, of course, for scenarios like those, where they threw on the biggest set of clothes they had and still ended up barely covered at all, yet still thought it was a good idea to open the front door and go out into the streets where everyone could see them. Surely, no one would mind a pair of synths whose bodies were almost fully visible to anyone who bothered to look in their general direction; surely, no one would mind watching a couple of self-proclaimed generates walking down the street, giggling to themselves and poking at one another with one hand while inputting numbers on a small console with the other. Surely, no one would complain when they both began fucking around with the size controllers keeping them at the state they were in at any given point, nor would they mind when said state became progressively larger. They were both already spilling out from the sidewalk, enough so that Gamma had to occasionally step onto the road and cause oncoming cars to swerve away to avoid crashing; a little more wouldn’t hurt, since they had broken through so many limits already, and if one little more didn’t hurt, then several little mores wouldn’t either, nor would even more stacked on top until the two of them were too busy being colossal to really care about what was happening around them. It happened quickly, yet subtly enough for neither of the synths to notice the fall into madness, at which point it was too late for them to do anything about it: Chi would punch some numbers in and have Gamma’s ass gain a couple dozen pounds to each cheek, while Gamma would turn around make both of Chi’s tits not only be about one and a half times their size and several more their weight, but throw in some extra height as well, just so he himself could hang out underneath the looming rack that was his mate’s gargantuan mammaries. And this carried on, fed by itself in an endless, self-feeding cycle that neither side had any interesting in stopping, not even when their clothes were torn to shreds, their bodies were so wobbly that just taking a step was enough to get them to create multiple unending shockwaves, and they were bumping into tops of street lamps without realizing it. Inch by inch, the silicone injectors, fed by a ludicrous amount of matter pumped into the replicators, kept on bloating the two synths, leaving them increasingly unable to walk without causing some degree of damage to their environs… and, after a point, increasingly unable to walk at all. They were still mechanically capable of doing so, albeit not without great cost to their endurance and stamina; sure, they could put one foot in front of the other, just like they could deadlift thrice their own weight if the conditions were right. It didn’t mean they would, nor that they had any inclination towards doing so. Indeed, they had better things to concern themselves with, such as what to do with all that backed-up spunk both of them had been lugging around ever since they left their home; it was almost incredible how most of their nut weight wasn’t even injected mass, but rather just their own productivity given enough room to actually fill. The size of the package might be enhanced, but that cum explosion waiting to happen was entirely their doing and no one else’s, as was the body-sized pillar of cock they were both sporting and not even trying to hide anymore. So much, just waiting to be serviced, and yet none of them could take the first step; to do so would mean to stop growing, since they’d be too busy impaling one another on shafts far too big for even their improved bodies to take, and if they were doing that, then they couldn’t well be making one another bigger, now could they? Better that they focus on what was important, like fiddling with their proportions even more, injecting near-endless quantities of mass into their bodies to better fill out their curves and contours, to better fill out in general, until they were outright unrecognizable compared to before. They might’ve been big already, but now, with full control over one another’s size, there was really nothing stopping them from going entirely overboard with everything, nothing stopping them from just making one another so gargantuan that it would be impossible for them to do anything but grow further. Not because they physically couldn’t, but because the physical high was so irresistible that to do anything else at all was seen as sub-optimal, even undesirable compared to holding their ground and making their mate grow bigger knowing the other would do the same for them. Thus it was that Chi and Gamma went from merely being large enough to cover a sidewalk and a good chunk of one lane, to becoming colossi blocking the entire street, pushing against the buildings on either side while slowly flattening whatever poor vehicle happened to be parked closest to them. They couldn’t help it, ‘twas too strong, too irresistible: from tits to crush houses and asses to cover city blocks, to a cock that rose far upwards and bathed the ground below in an endless, thick rain, they had everything they could ever want… in quality, at least.

Quantity, however, was a different matter altogether, and they were nowhere close to where they wanted to be. Where exactly all that extra mass was coming from was anyone’s guess, but neither Chi nor Gamma were about to complain; as long as they kept growing, it didn’t matter where the silicone injections came from.

Just that they kept coming.
