Arcade Day (Birthday Gift for Raibrid!)

A day at the arcade was probably not the first thing anyone thought of when the word “birthday” came to mind, but to Rai it was a throwback to simpler times, when they could afford to waste an entire afternoon dumping coins into stupid, worthless tickets that were only valuable in the same way as a fair token had value. Back then, all that seemed to matter was getting the highest score possible in order to bring home the favourite toy du jour, a bit of a nostalgic, rose-tinted feeling that the moodragon was very interested in trying to recapture.

The clerk by the door gave them a bit of a stink eye once they came in, presumably due to the durg’s expansive assets; much as they did their best to try and cover up, it was hard to contain a pair of sloshy milkers that covered half their chest, even if they brought along the loosest shirt in their wardrobe. For a few moments, Rai honestly thought they’d be asked to leave in order to avoid making a scene, but seeing as there weren’t any kids around (and thank goodness for that, since it was a Thursday) the staff probably saw no reason to press the issue, leaving the moodragon with nearly the whole establishment just for themselves!

Games of chance had always been a favourite, if only because their younger self found the element of risk so delightful as to make all their victories be worth so much more than they actually were; of course, as an adult, Rai recognized that it was just a scheme to siphon coins off of dumb kids who didn’t know how maths worked, but they had a job now, so if they wanted to drop ten quid on a stupid ball game, no one was going to stop them!

The first stop were the slots. Those hadn’t been there when they were younger, and never having had the “pleasure” of visiting a casino, at least now the durg got to experience the thrill of pulling a lever and waiting for something to happen. It was so simple, too; in a way, they could see why they were so popular. All it took was a coin and a pull, a coin and a pull, and suddenly they were five quid down with absolutely nothing to their name. Time flew by like an arrow, leaving them both incredibly surprised and slightly mortified at how quickly the machine grabbed their attention and yanked it out of their control. Feeling like it would be best to leave that particular spot, Rai inserted one last coin and rolled for their luck, only to find the machine refused to stop.

At first they assumed it was a mechanical failure of sorts; the three wheels kept spinning for far longer than any other try, and even though they knew it was ridiculous to think that way, part of them hoped that it meant they were owed a jackpot. How disappointed they were when the machine finally stopped, and how surprised the moodragon ended up being when they saw a full line of… glasses of milk? Or at least some other kind of white liquid, though their initial suspicions were soon confirmed.

Rai was no stranger to feeling their chest grow; they’d been going through that for most of their adult life, with the occasional temporary growth spurt often adding a handful of cup sizes to their bust after getting drained down. Thus, when they felt the familiar sensation of fullness in their chest, the only thing they could do was smile, because at long last they had found something they could do to have some fun while growing. How exactly the machines were interfacing with their biology was a complete mystery, but Rai wasn’t going to complain; if it meant they got to enjoy themselves while also packing some milky weight onto their bosom, then they knew what they were gonna do for the rest of the afternoon.

After the first boost at the slots, their breasts were already hanging just below the navel, giving the moodragon the best excuse to go play some dancing games while they still could. It was up in the air whether or not their top, already strained and audibly complaining about the sudden increase in pressure, would open wide, rip apart or miraculously hold, but that was honestly part of the fun; Rai had the whole place for themselves, after all, so even in the “worst” of scenarios, all they’d have to do would be to apologize and use the tattered remnants of their clothes to make themselves decent.

The dance machine was still in the same place as they remembered them being, tucked away in a corner and with just enough room for a small crowd to gather. Rai remembered the good old days, when they’d be surrounded by a dozen or so people of their age, all cheering them on as the high score kept climbing to greater heights. To think that they’d be using the same machine for a purpose as lewd as the one in their mind was… delectable, to say the least.

Another coin, and the show was about to begin. Picking a song completely at random, wanting to test what failure did to their bustline, Rai took up position and stretched their limbs, allowing muscle memory to take over. It’d be just like before, except now they had two colossal weights strapped to their chest and really wanted to win. Two big sources of motivation right there, especially given how loud they were.

In a surprising (and more than welcome) twist, the game didn’t wait until it was over to start affecting them. Every thousand points or so, Rai felt their body becoming… more. It wasn’t merely their tits, even if they seemed to be getting a larger share of the growth pie, but just about everything else as well; dancing became progressively harder when their thighs thickened and thighs widened, making it difficult to get into position when the dragon’s asscheeks burgeoned outwards with so much extra mass that, oddly enough, it was their tight-fitting pants that saw the first rips, with their scaled flesh spilling out from the holes and clapping loudly each time they jumped. After a certain point, it was just impossible to do anything, and with a final grunt, Rai fell onto their side, collapsing off the machine and feeling the best they’d ever had in months.

They couldn’t even see their curves properly, and at that point it was unbelievable that their clothing was still holding on. Whatever force had linked the machines to their body was clearly working its magic on the fabric as well, because that shirt was not meant to stretch out that hard. Getting up before any of the staff could get to them, Rai took a moment to appreciate just how large they’d become, having to stifle a gasp after taking it all in.

Their milk-filled tits were still the center of attention, obviously, already so bloated that it was a wonder the dragon could even move at all, making the time they lasted on top of the dance machine nothing short of some kind of weird cosmic anomaly; they hung absurdly low, low enough that they grazed against the ground whenever they tried to move, and yet rather than sagging, the top of their curvature was about level with the moodragon’s eyes. They’d become so stuffed that their body had done something drastic to compensate, something it’d never done before: between their legs, just above their most intimate bits, something else had grown. Something big, soft, pudgy and leaky, something capped with four fist-sized teats and already leaving underneath it a trail of hot, oozing milk.

Udders.

The realization left Rai so shocked that they didn’t even know what to say. They were going to take a look at how big their ass had gotten, especially since it seemed to also be rubbing against the floor despite them standing up, but to suddenly feel those things plop against the ground and rub on it whenever they tried to move had left them bereft of a reaction. What exactly were they meant to do now?

The answer was grow, obviously; those udders seemed to be getting all the run-off from the leakage their tits weren’t going through, courtesy of the nipple piercings holding back the tide. Whatever their production was like, it had to be immense if that part of their anatomy escaped the containment field provided by the charms on their ears; just the thought alone was enough to make their legs quiver.

Even more so once Rai remembered that they’d only gone through two machines and were also so massive they had difficulty walking. If this is what they were like now, who knew what their body would turn into once they did a full lap around the arcade?

Well, they would know. And there was only one way for them to know.

The next thing on their plan was one of their favourite games, even if the element of skill involved was little-to-nonexistent; all that was needed of the moodragon was to drop a ball onto a rotating panel and hope it fell on the right hole. Nothing more, nothing less, and now that Rai knew what their body was going through, it was time they put those coins to good use by wasting them all trying to make themselves bigger.

It was even easier than they initially thought; rather than only receiving a boost on a pay-off, every single ball dropped made their whole body bloat by a varying amount, dependent of course on their overall score: miss any good targets and it was just a cup size or two, but every time that ball went down somewhere that mattered, all Rai could do was take a few steps back and let their body strain their clothing even further closer to the breaking point, until the two nipple piercings designed to keep their milk from flooding the building began to tremble as they tried to hold on despite the mounting pressure behind them. Within a few short minutes, even reaching the machine at all was (quite literally) beyond the moodragon’s reach, with their breasts alone having grown to such a size that, were they not resting comfortably on top of Rai’s udders, they’d be dragging along the floor!

All of this would typically be enough for the dragon in most days. They got what they wanted, became massive, developed udders and even threatened to destroy their own containment with how much milk they were producing. But there was something that day, something different about everything; rather than that familiar voice showing up to tell them that they’d had enough fun and should probably try to shrink down, Rai was instead faced with… nothing. All of a sudden, there were no brakes to keep them in check, no sanity to hold them back. Just their own growthlust, the means to sate it, and the resources required to put whatever deranged plan they had in motion. It was a testament to how amazing it was that Rai even managed to think about it for five seconds before just losing their mind playing around the arcade; the revelation was simply too sweet for them to pass up. It had to be savoured, appreciated like a fine wine, for it might very well be the last time in a long while before their mind remembered to impose limitations again.

The moodragon only left the ball-dropping game after it was too broken to function, something that took a good ten minutes before each of Rai’s tits grew to rival their owner in sheer size, climbing up the sides of the machine until it broke from the strain and fell to pieces on the ground. Giggling like a lunatic, the moodurg turned around, bringing with that simple motion such a mess of gurgling and sloshing that the few staff present at the time were all too dumbstruck to really ask why their only customer had just broken one of their best moneymakers. Rai was far too busy indulging in their own fantasies to really care, either; for once in their life, they’d be given the opportunity to just walk forward and drag people along whether they liked it or not, flattening their bodies against a pair of milk-swollen mounds so unfathomably densely-packed that Rai was essentially just counting down to when their piercings would break down completely.

They could’ve done something to stop it, even a gesture as simple as removing them… but that wouldn’t be fun. That wouldn’t give them the satisfaction of feeling the pressure build as their tits blossomed into two colossal, jiggling orbs that became harder to move around with each second that ticked by, wouldn’t let them appreciate as their body built up more and more and more of its lactic bounty until, in a moment of purest, utmost bliss, the invisible threshold was crossed and everything went straight to dairy hell, with everyone to the front of those milkers being fired off at great speed towards the entrance to the arcade, spared an impact with glass panes purely because the jet of cream had already broken them into millions of shards.

On the outside, passers-by and cars alike were surprised by the sudden appearance of two high-pressure jets of a mysterious white liquid, ones strong enough to force traffic to stop in its tracks when it completely blocked the road. At the very least the sudden deluge of milk didn’t run the risk of flooding anything; with the building it came from being right by the sea, both spouts were safely deposited straight into the saltwater, staining its surface white while giving their source yet another reason to let loose; why bother with limits when they weren’t even at risk of destroying anything but the local sealife?

There were plenty of machines left for Rai to pick from, but only one would give them the explosive finale they wanted. It was almost too good to think about, hence why they stood around wondering if they really should for a while before their feet began to move of their own volition. The game itself was quite simple: you spun a dial and hit a button to stop it, and if you did it properly, a large balloon would be inflated by the amount you landed on. Get it just right and you’d hit the jackpot, filling it up so much that it burst! There was honestly no better way for the moodragon to exemplify what they were going through at that exact moment, and if the pattern of growth continued, then the mere idea of being pumped up like a milky balloon was… well, Rai was lucky their legs were as strong as they were, or else they would’ve collapsed under their own weight from how much they were shaking at the prospect.

It was so easy as well; the machine itself was positioned in the center of the far wall, giving the moodragon plenty of room to drag themselves over, even if they had to tear apart a large chunk of the ceiling in order to do so. Once by its side, it was simple enough to aim their bust so that, in the unlikely event of a jackpot, it would at least explode outwards towards where it would do the (comparatively) least harm; the building itself only had the arcade in it, and it was a hot day, so submerging those tits in the water might even be a suitable cap to their experience!

The coins were inserted and the dial began turning. Again and again Rai hit the button at just the wrong time, inflating the balloon and themselves in wildly unequal measures; whatever happened to that overinflated red sphere in the glass box was multiplied a thousandfold in each of Rai’s tits, with plenty reflecting on their bottom as well, until they were forced to stretch and bend their back in weird ways just so they could reach the machine at all, pinned as they were on one side by two hyperactive milk factories and on the other by an ass too wide to even move anymore.

It was all worth it in the end, because, against all odds and common sense, Rai did it. Through blind luck and the tiniest bit of skill, the dragon hit the jackpot dead-center, earning themselves not only a wealth in tickets, but a grandiose finale to what had been one of the best days in their life. The machine kicked into gear, pumping the balloon with enough air that it began to creak loudly, while Rai’s own breasts swelled with newfound mass and milkiness, the building crumbling all around them. Through some unknown mechanism, the structural foundation refused to yield, pressing on all sides and making the moodurg feel like a sardine in a can; it was like being half a second away from bursting at all times, something made worse by how the balloon that caused it all was very obviously going to pop within seconds.

And then it did.

And everything came crashing down.

Just as the balloon burst open, so too did Rai’s bosom explode with new size, utterly obliterating what remained of the arcade’s building and sending all of it flying into the sky, only to fall onto the ocean or parked cars half a mile away. Their tits continued to swell at an impossibly-fast rate until, with an enormous splash, they collapsed most of the promenade and fell onto the sea below, only then halting their advance and leaving the moodragon panting after basically doubling in (already prodigious) size in just a few seconds.

Nothing happened for the longest time, save for those small hills continuing to “pollute” the water with their pressurized jets of cream. A small crowd was gathering, but Rai didn’t care.

Best. Birthday. Ever.
