Sudden bulk (Patreon)

**This story contains: hyper muscle growth, hyper cock growth, excessive cum, hyper balls, vast destruction and probably some other extreme stuff.

Somewhere in the Nevada desert there was a secret government facility. Nobody could tell for sure what was going on in there, but the rumors suggested that they did illegal human experiments, something about improving genetic potential. The facility kept operating in secrecy for many years, the people there doing God-knows-what behind closed doors until one day. This was the day everything got completely out of control. A deafening boom could be heard for miles as the main building started shaking to its very core alongside the entire complex. Windows started shattering one by one and a few seconds later the entire main building collapsed, a giant humanly figure literally bursting out of the steel and concrete ruin. It looked very much like a man, but his body wasn’t anything human. His muscles were rapidly expanding in all directions, breaking apart everything they came across. They were all huge masses of hard flesh, completely riddled with enormous veins that fed them and made them grow bigger with every second. The man’s pectoral muscles produced the sound of a rubber stretching to the extreme as they became bigger and wider, grinding against one another as their mass continued to increase. The distinctive sound was also accompanied by the powerful moans of the massive being that appeared to be enjoying the transformation very much. His pecs grew so large that they started pressing against his oversized arms, fighting for room with his bloated biceps and rapidly expanding triceps. The giant’s head was quickly swallowed up by the sea of solid beef that quickly piled up on his torso while his deltoids and traps ballooned to ridiculous sizes. A massive wall of throbbing bulk and veins surrounded his head, threatening to cut off his air supply and even crack his own skull if it kept growing at this rate. Thankfully, it left him just enough room to be able to breathe, at least for now. His lower body soon followed, quickly blowing up with ludicrous amounts of hard beef in order to keep up with the rest of him. His legs exploded with new mass, growing from the size of Greek columns to water towers in record time. His quads and calves were so strong and thick they could easily support an entire downtown mall full of people and even squat its total weight for thousands of reps. Once the dust finally cleared, the titanic being that now loomed at over 300 feet in height could be seen in all its monstrous glory. The musclebound colossus growled as his immense bulk got touched by the warm rays of the sun for the first time in who knows how many months. But he was just getting started. He continued to grow larger and more monstrous, his eyes shining bright and his face slowly getting covered up with fat pulsing veins. His back broadened further as more and more muscle mass continued to pack up, making his back look more like a 3D map of massive hills and deep valleys. “Must… get… bigger!!” the monster groaned, his voice barely audible through the mountain of bulk surrounding his tiny head. Giant veins were now racing from his bulging neck to the rest of his gargantuan body, spreading everywhere like wildfire, fueling his muscles with the gallons upon gallons of blood they desperately needed. His continuously swelling deltoid muscles were starting to have trouble with his bulging shoulders and ridiculously bloated arms. His humongous biceps rose like mountain peaks that forced his arms to his sides and made it extremely difficult to flex them anymore. He still tried though, causing those gigantic bulges of veiny bulk to press against his other massive slabs of growing meat. His muscles crushed everything in their path, no matter if it was natural or man-made. It took less than a minute for the former government facility to turn into nothing more than a distant memory.

“SO… GOOOOOD!! FUCK!! NEED… MORE… MASS!!” he groaned as his body started pumping itself bigger and freakier yet again, this time with even more vigor. The insane size felt simply amazing. He was addicted to his growing bulk. It felt like his body was oozing raw strength from every pore. It needed to fill more space with its wonderful bulk, to consume every square inch in every direction and put it to better use. Just trying to move his arm or leg made it obvious that he’s lost most of the flexibility he once had. It looked like the mass of his body was pivoting around a core as stiff as a giant rock. But flexing felt fucking incredible, like the hardest pump he’s ever had magnified by a million. Of course, flexing became harder and harder for him to pull off because of his ludicrous size. He could almost feel himself sinking into the ground, the earth itself starting to give in under his imposing weight. He was becoming so fucking big and heavy, but still wanted way more. “I NEED MORE FUCKING MASS!! I’LL NEVER GET TIRED OF GROWING!! LOOK AT THIS FUCKING BODY!! SO MASSIVE!! SO PACKED WITH HOT MUSCLE!! I NEED MOOOOOOREEE!!” he moaned as new massive veins appeared all over his giant hulking frame. At this point, he just wanted to get his hands around the fleshy balls of muscle all over his enormous body and feel them expand. He wanted to feel his muscles, to worship them, to feel their supreme hardness as they continued to blow up in all directions. Every single inch of his body was rock hard, perfectly shaped, just throbbing with raw power no one could ever hope to contain. On top of that, there wasn’t any ounce of fat left on his body, just thick shredded muscle. His hunger for mass was unending and his body was responding by giving him exactly what he desired: more beautiful mass, more striations, more fat pulsing veins and more inches in height to properly fit them all. His monstrous mid-section now sported a bloated 12-pack and another pair of abs could be seen slowly rising to the surface of his tight skin as he grew taller. He was completely addicted to his humongous body, now standing proudly at 400 feet in height and not showing any sign of slowing down. He would sooner die than see it stop growing. The last growth spurt was the one that finally awoke his humongous cock.

With an animalistic grunt, the monster cock became hard as a stone pillar, shamelessly basking in the cool breeze like a veritable monument of virility. He tried to grab it with one hand as he used to whenever he got aroused, but one hand was clearly not enough. Astounded by its massive weight and its insane thickness, he had to put use both hands in order to hold his majestic phallus. It’s been leaking for quite some time, but his orgasmic muscle growth somehow managed to take center stage and make him forget about it for a while. But that titanic cock couldn’t be ignored any longer. Huge drops of pre were dripping from its fat cockhead while the monster grinned, deeply satisfied by how wonderful it felt to hold his insanely large rod. The only problem was that it won’t be long until his muscles would be too large to allow him to stroke it properly. His balls were so big they resembled a few regular cars welded together into perfect spheres, sporting veins so large they could easily be mistaken for gas pipes. Those massive nuts were throbbing like hell, signaling they were working in overdrive to produce the thickest and most potent cum that ever existed. With his cock fully erect and the growth appearing to be slowing down for a little while, the giant started stroking his colossal dick. It was incredibly hard to engulf the massive throbbing member he now possessed between his colossal legs, but his humongous muscles proved to be the ideal tool for jerking off in his current form. “COCK… FEELS… SOOOO GOOOOD!!” he said as he struggled to pleasure his throbbing cock, each complete stroke sending shockwaves all around his massive frame. His cock continued to leak ridiculous amounts of pre as he jerked off in the middle of the desert while his balls kept getting larger and so full of cum they started hurting. Even though the pain was rapidly increasing, he wanted his cum-factories as big as possible. He wanted to use his orgasms as a source of growth, thinking that the explosion of cum was the powerful stimulant his muscles needed to take the growth to the next level. He was nearing 600 feet and more pounds of bulk than anyone could be able to measure, yet he was nowhere near satisfied. He started roaring like a wild beast as he felt even more power being pressed into each and every one of his hard muscles, forcing them to explode again, adding even more mind-breaking strength and size than before. His cock was spewing precum like a legit waterfall, his muscles slowly engulfing every inch of the monster rod, making it feel better and better with every passing second. He was essentially giving himself a “muscle-job”, except the term hadn’t been invented since no one had muscles that massive or a cock that huge. Judging by the intensity of their pulsing and their disproportionate size, even for a body like his, it was clear as day that his balls were nearing their breaking point. They had stored so much cum he could easily cover half the desert with his abundant seed. His muscle-stroking proved to be just what his body needed to become even more ridiculously huge. Muscles on top of muscles, the hulking behemoth kept moaning and jerking off as his body sent him into a bulk-filled bliss. “Muscles” and “cock” were the only two words on his mind now. He couldn’t process anything else except the intense pleasure he was experiencing all over his body.

The moment the lustful growth seemed to be coming to a halt, the giant realized there was no point in holding his load in anymore. On top of that, his balls were so painfully bloated that if he didn’t release all that stored cum, his balls were gonna burst for real. “CAN’T… HOLD IT… ANYMORE!! GONNA… CUUUUUUMMM!!” the giant moaned as he felt every slab of thick muscle on his colossal frame flex at the same time, instantly sandwiching his entire cock with a sea of bulk and making it release its pent-up load. His balls contracted so violently that they cracked the ground below him, making his heavy body sink further down. With his giant member standing firmly at a 45-degree angle, he started firing with everything he got. His load seemed endless, painting everything in sight with a thick layer of cum and also giving the scenery the distinctive smell of his seed. The powerful orgasm triggered another growth spurt, this one doubling everything that came before and pushing his body to new extremes. He was completely lost in his orgasmic bliss. His cock kept spewing load after load until it covered everything for dozens of miles. It took nearly 15 minutes for him to finally regain most of his senses, yet his cock still had many more shots left to give, although much weaker ones. When the thunderous release finally came to its conclusion, the whole scenery was completely different. He couldn’t believe how much he came and how much bigger he got. His body was nothing but extreme shapes of muscle mass, so much shredded mass it was ridiculous. His cock and balls doubled in size too, separating the left side of his body from the right one just enough for him to not suffocate under all that immovable bulk. Standing at a whopping 1200 feet tall, there were muscles everywhere he looked, so much throbbing mass that he could lift a whole fucking mountain and not feel any sort of challenge. The challenge was the simple act of moving at this point. He simply couldn’t. But it didn’t matter. He could feel his body wasn’t anywhere near done growing just yet. If he couldn’t move anymore, then he simply had to force his body to grow by sheer willpower. His body started convulsing violently as one single word could be heard echoing from deep between his monstrous bulk: “MOOOOOOOREEEE!!!”
