Hey everyone! Here's another one of the results of the YCHs stories that were done on my FA a couple weeks ago! There were lots of takers for this one, and the version I chose to upload is FA: Foulsbane 's, who asked for a bit more personalizations (cough bigger cough) for his lovely boy Rory!

Summary:

Rory stumbles upon an outrageous AD for an app that promises all the gains with none of the pain and none of the work. Rory tries it out, and who could have guessed, the app actually delivered its promise! Except that the app was in an open beta state and one of the features that Rory uses is currently bugged... giving him a lot more EXP than it should! Every level up gets crazier, and soon Rory no longer looks like a cute little twink femboi, but has become instead a titanic musclebound hunk with hyper cock and balls capable of flooding entire rooms!


"Hey you! Yes, you! See that guy over there spending hours every day exercising to get buff? Or that other guy who's restricting his diet to lose weight? Or this one guy trying to use pumps to enhance his manhood? What if I told you it's possible to get these gains in another way? While lazing around, while eating as much as possible, or even while sleeping! Look no further! Download Idle Gains and you too can attain the body of your dreams with no effort other than waiting for XP to passively stack up!"

Rory stared at the screen of his smartphone, dumbfounded by the audacity and the shamelessness of the ad he had been shown. And yet, while feeling offended by the absurdity of it all, there was something oddly enticing about the promise of this application that made him playfully grin. For almost a whole minute the femboy magidog stared at the screen, hesitating about tapping the button that would take him to the store to install an application with dubious advertising.

And then, he did it. He tapped. He was brought to the store and saw that the application was a free to play game. Despite the lack of any review and a number of installations that was barely reaching a hundred, it genuinely looked interesting. And besides, it was an idle game, these usually weren't too much of a timesink and Rory might get a kick out of staring at an avatar of himself becoming beefier.

A couple minutes later, the download was complete and the application was available. Upon opening it, Rory was welcomed by the logo of the game, followed by a loading screen. The application requested access to the camera, which made the dog raise an eyebrow. He figured it would be harmless, so he allowed Idle Gains to use the camera, and much to his surprise, it actually immediately did, taking a selfie of the cute femboy and importing the photo into the game.

Startled, Rory stared at the photo of his dubious face and stared at the question "is this you?" on the screen. Not wanting to have this dumb face on the game, he tapped "no" and retook a better selfie where he wore a more playful expression with his tongue stuck out, and then proceeded further.

Upon looking at his profile in the game, Rory was surprised to see an accurate three dimensional model of himself in the nude. They even got the various shades of brown and beige perfectly correct, down to every single hair. Underneath this turntable of himself was a bunch of sliders with all sorts of labels. Height, muscle definition, breast definition, weight, cock length, balls size, balls productivity, and so much more. There were also options for colours of his eyes, fur, and everything he could possibly imagine, including a dropdown with every species he could think of.

Rory fiddled with the settings for a bit, putting a lot of focus on muscle definition, some on height and a lot in all the virility settings. Afterwards, he explored the game until he found a checkbox labelled "auto-allocate experience (EXPERIMENTAL FEATURE)," which he enabled. The active part of the game was actually interesting, so he spent about three hours on it before getting bored and closing the app.

Later that day, Rory was in his bed, ready to go to sleep. He was browsing social media on his smartphone when he got a notification that read "Idle Gains (Open Alpha) - You have levelled up!" Not feeling up to go and play that game again, the dog quickly dismissed the notification. Not even a couple seconds later, his whole body was invaded by a wave of heat. To counter the sudden rise in temperature, he pushed his blanket aside. Still reading social media, he failed to notice that his body was slightly changing. Every pump of blood in him was making him swell slightly bigger and more muscular. After a minute of this weird feeling, Rory received a text message coming from Cai, a very good friend of his. A picture of the naked and fully hard peach-furred fox captioned "miss you, wish you were here!". The fox often teased Rory in this manner, sending nudes at the most inconvenient of times. However, it was perfectly timed today, as the magidog could feel a stir in his briefs from the heat invading his body. Without taking his eyes off the fully exposed dick of his crush, the horny magidog brought a hand in underwear and cupped his balls while feeling his erection poke out of his sheath.

And then, suddenly realizing that something felt off about his junk, Rory let go of his phone and sat on his bed. He lit up the light in the room and looked down. His erection was severely tenting his underwear. Far further than it ever had. He also noticed that his belly and chest were covered in some budding muscles. Confused, the dog touched his belly, feeling up his newly enhanced abdominals. He pulled his underwear down and was greeted with a huge erection. It was easily ten inches long and three large, and his knot wasn't even formed yet. His previously cherry-sized balls were the size of apricots now. He gasped at the sight of his enhanced genitals.

For some reason, he felt extremely aroused. He brought one hand on his large member and began rocking it up and down, while he used his other hand to cup his balls. He closed his eyes and pictured images of his fox friend that would arouse him further, slowly accelerating the rhythm of his masturbating and making his knot swell in his sheath.

With the increased sensitivity that came with the change, it didn't take long for Rory to reach orgasm. Pleasure filled his mind, his knot was set free and cock throbbed hard, firing a large spurt of cum that landed against the wall. And another, and another. So much seed splattered against the wall. The semen was dripping, falling down on the floor of his bedroom. A fourth shot was fired. And a fifth, with still the same intensity as the previous shots. It felt like every blast of cum that was fired was as plentiful as a full orgasm from before his change.

A tenth shot was fired from his dick, finally weaker than the other ones. Rory huffed loudly, his mind completely overrun with pleasure. He let go of his length, which was brought down by gravity, a last bead of cum dripping down from its slit. And then, the dog cursed as he realized the mess he had made against the wall. Half an hour of intense scrubbing, three towels and a change of bed sheets later, he finally got rid of most of the mess and let himself fall on his bed. Curious about the game, Rory opened the app and saw that his avatar had gained a ton of stats. He used this sudden increase in strength to power through a few dozen levels, accelerating the rate at which experience would passively accumulate. Grinning, he set down his phone on the bedside table and slipped under the covers.

The following morning, Rory woke up drenched in his own cum. His libido had gone up so much that his whole night had been filled with lewd dreams that caused him to orgasm every few hours of sleep.

The dog turned on the shower. While waiting for the water to run warm, he was admiring himself in the mirror, delighting at the sight of his new budding muscles and his junk. He looked larger than the previous day in all regards, while still somewhat retaining his thick thighs. Broader shoulders, taller frame, thicker muscles and heftier genitals. Even his sheath looked much larger and fuller thanks to the level up in the game. He considered rubbing one out right now as admiring himself was making him horny, but decided against it; he really needed to clean all of the dried cum off his fur.

Steam started rising in the bathroom, signalling the femboy that the temperature was just about right. He stepped inside under the running water when his ears picked up the sound of his phone vibrating. Wondering what it could be, the dog started scrubbing the dried cum off his fur. The heat of the shower was very pleasant, almost erotic. Combined with him rubbing himself to clean himself, he was getting aroused quickly. One hand was rubbing around his chest, the other his abdominals, somehow feeling them grow stronger ever so slightly. His half-hard cock was rising, engorging with blood at a fast rate.

Up until that point, the dog hadn't noticed the heat spreading throughout his body because of how hot he liked to run his showers, but he snapped back to himself when he sensed that something was up; his bathtub was getting more cramped with every second. Looking down, his eyes shot wide when he witnessed his manhood throbbing hard against his belly. Only the knot was still hidden in his sheath and yet still it reached so high against his top row of abs. He ran his hand from his swelling eight pack to the base of his shaft and grabbed it, starting to pump it up and down. Instead of just rubbing his thickening pectorals with his other hand, he started playfully teasing himself, feeling his muscles expand yet again. Within his grasp, his erection kept on growing larger and thicker, way past his fully hard size of the previous day. Soon, Rory's head rose above the showerhead, which was now spraying water against the throbbing monument of the magidog. At this point, he could no longer be called a femboy with how tall, thick and muscular he had become.

The dog's knot suddenly swelled and exited the sheath, bringing the enormous tool to two feet and half of dockcock. The pressure became too much for the horny magidog. His now cantaloupe-sized balls churned audibly, unleashing their contents. The dog's enormous shaft began spraying cum that splattered over the curtains and the ceiling. The orgasm was so intense that his whole body shivered with every shot of seed. It pumped semen again and again and again, adding layer after layer of cum in the steamy hot bathroom's ceiling. The drain was completely unable to evacuate the sheer amount of semen and water that was falling in the bathtub.

A few dozen shots of cum later, Rory's orgasm finally faded, his cock leaking remnants of his orgasm - large drops of seed - while softening slowly. Calves deep in a tub filled with splooge, the dog went back to cleaning himself as if nothing had happened. While waiting for the drain to empty the tub of the cum so he could clean his legs properly, Rory thoroughly enjoyed rubbing his enhanced muscles.

After being done with his shower and drying himself with thrice as many towels as usual to completely dry his nine foot frame, he confirmed his suspicions. There was a level up notification on his phone from Idle Gains Alpha. Grinning, the dog went back into the game and used his avatar's newfound strength to rush through nearly two hundred levels again, boosting his passive experience gain once again.

The giant dog saved his spreadsheet on his work computer and sighed heavily. Having to deal with his coworkers asking him all sorts of questions about his miraculous growth had drained Rory. Some of them didn't even recognize him because of how huge he had gotten. Thankfully, he did have an office for himself and people usually left him alone whenever he closed the door. He had to borrow a set of clothes from a large friend of his, and even these were almost too tight on his massive frame. They were so snug that he couldn't even button up the top of his strained shirt.

The large magidog took a small break from his endless copy-pasting to stretch his sore arms, almost ripping a few strained seams because of that. He really needed a breather, but he didn't want to leave his sanctuary of questioning-free tranquillity, so he instead just pulled his phone out of his pocket.

A series of unfortunate events happened as soon as he opened his social media app. His eyes fell upon another message from Cai, his fox friend, who once again had sent a file of him handling his pre-dripping cock, captioned "Roryyy~ Don't ignore meee~ I need youuuu!!!" Not only that, but there was a large play button on the image. And to top it all off, a notification popped on his screen, he had levelled up again in Idle Gains.

It was possibly the worst time for this combination of events to happen all at once, from the point of view of the dog's career. But the excitation and anticipation for what was to come was too much for him to resist. The stir in his stretched pants was too strong. He started the video and brought a hand to the growing bulge on his groin while staring at the video of his friend stroking his cock while moaning. The underwear that Rory had struggled fitting his junk in earlier this morning ripped open under the pressure brought by the blood being pumped in his member. His balls gurgled, sloshing ever louder and engorging bigger, rapidly filling up the space between his thighs.

Rips and tears could be heard from the dog's office. Rory's shirt ripped around his strengthening shoulder, tore apart around his large biceps and thick pectorals. The front of his pants was ripped open by his enormous erection, which was already leaking plenty of pre on the carpet of his office. The horny dog brought his second hand to join the first in grasping his throbbing cock, utterly failing to encircle it fully because of how thick it had become, and began rocking it up and down along the length. Every single muscle in his body was burning and growing thicker, adding more rips and tears in his already ruined clothes. His pants' sleeve burst around his calf, and the other sleeve was torn to shred around his massively expanding thigh. The back of his pants snapped in two, freeing his thickening ass.

Rory's breath became heavy and labored, he was staring down at the video of his friend, secretly wishing he could suck on it or sit on it. His socks snapped open, finally ridding him of the second to last piece of clothing. The last one followed suit soon after, his collar was torn in pieces when his neck and traps thickened enormously. Right before he reached orgasm, his body pulsed bigger in one massive growth spurt that brought him to nearly fifteen feet tall, with the muscle definition of an experienced bodybuilder, with a cock that reached all the way to the front of his muzzle, and with a ballsack as large as a beanbag chair, containing enormous balls that were aching for release.

The first blast of cum that was ejected from the dog's cock was accompanied by a loud moan and a jolt of electricity to Rory's pleasure-addled mind. Seed splattered all over the ceiling, almost piercing the plaster of the ceiling and completely covering the lights in his jizz. It easily lasted twenty seconds of uninterrupted flow before his body relaxed a little, only to prepare for the next shot.

Blasts of jizz were fired while he moaned out in pleasure, feeling his aching balls produce far more than what his cock was currently shooting. Layers upon layers of seed were added against the already drenched ceiling. Each shot was so powerful that it splattered in the room, sprinkling everything with drops of his jizz; from the walls behind him to the door in front of him, also ruining his desk, a few plants, the window behind him and a printer. The only place safe from his white flood was directly under his desktop and under himself, the rest being showered in his potent cum. Though even that safe place would not stay safe for long, seeing how fast the seed level was rising. Waves after wave kept on coming, and the gigantic magidog kept on whining-moaning as his enormous shaft so desperately tried emptying his balls.

When finally the flow of cum weakened, half an hour after it started, Rory felt completely spent. Drops of cum were falling down from the ceiling, dripping down on his office computer, on the furniture, and all over himself. There were nearly three feet of his seed in his private office, completely ruining everything drowned under the virile ocean. Every piece of electronics that wasn't protected from the cum shower was also destroyed. Thankfully, the cum hadn't reached the top of his desktop, where his phone was laying down.

The dog's sensitive ears picked up noise from the corridor, so he quickly got back to his senses. He immediately grabbed his phone - which was mostly protected thanks to the cover - and looked at the window, wondering if he would even fit through there. But he was just way too large, so he took a deep breath in, shielded his face with his arms and ran through the glass, shattering it with ease. A cascade of jizz fell down from the building, and as soon as he landed on the ground, he began running away. There was no way he could salvage his job with what he had just done, not that he minded resigning on the spot.

While running away, leaving a track of drops of cum behind himself, Rory felt his smartphone vibrate. A chill was sent through his spine, and he feared that it might be another level up. It was however something else; an important notice linking to the forum of the game, which read:

"ATTENTION IDLE GAINERS, a critical bug has been discovered with the auto-allocate experience experimental feature, where the experience that was allocated was anywhere between ten to a hundred times greater than it should have been. A patch has been uploaded and will install if your apps auto-update. If not, please manually update the game to disable this feature while we work on a proper fix for the feature."

Rory had however disabled the auto-update. And for a moment, he considered sharing the discovery of this game with a certain peach-furred fox. But before doing so, he would first pay him back for sending the messages by giving a very up-close and personal show with a gargantuan horny magidog.
