A growth epidemic

by SomeMuscleGuy   

After being exposed to a new virus that has been growing men around the world into oversized freaks, Alex tries to do everything he can to stop the inevitable, unaware that he caught the most infectious strain yet.

No. No way this was happening. Not already.

I took a deep breath as I looked down at my arm. I knew I was too late. This is what happened to everyone who caught the virus. A singular black vein spread from where I was exposed and went up through my arm, disappearing underneath my clothes. All the scrubbing and precautions I took did nothing. Just an hour ago I went on an essential run to the store to get some water when it happened.

I was heading towards the check out when I heard moaning coming from the aisle on my left. Instantly, my heart dropped as I turned my head. What I saw was the last thing I ever hoped to see. Splayed out in the aisle was a man. Not just any man. But a very big, oversized man. All of his muscles looked like they had been inflated beyond anything that was possible on Earth. In fact, I could see tens of pounds forcing themselves onto his body every second. He was stuck on his back, practically immobilized from his own size as his clothes lay torn all around him. I estimated him to be around 10 feet tall and over 5,000 pounds. The most impressive part was his package. It had to be nearly 5 feet long, with balls that perched it up over a foot high! I couldn’t even see his face over his immense pecs! This human was definitely the largest I had ever seen since the outbreak started, and by a wide margin too.

The moment my brain processed what was happening, I tried to get out of the way, but it was too late. A large arc of cum was already flying in my direction. I was nimble enough that I was able to get mostly out of the way, but a few drops hit the top of my right arm as I ducked behind the shelf. I gasped, instantly sloughing it off with my hands before I realized that I was further contaminating myself. I picked up the water from my shopping cart and instantly went to work, desanitizing myself as quickly as possible. The shelves began to tilt as his body continued to swell, and that’s when I took my queue to run out of there. He must have only started growing mere minutes ago.

The world only caught wind of this a couple weeks ago, and since then, society has spiraled out of control. No one truly knows how it started, but tens of thousands of people across the United States alone now have found themselves growing into much larger beings. Typically it ranged anywhere from a foot of height and dick, to around 500 extra pounds of muscle. Only a few breached beyond 8 feet tall, and even then, even fewer broke 2,000 pounds. Still very much human, but enhanced in every way. Especially in size and pleasure. The virus was only found in males, and only spread through direct contact with semen, which is why most of the men that were growing happened to be gay.

Even over just the last few weeks, the growth started to become stronger. More intense. Larger. If it kept scaling up like this, it could cause irreversible changes to the world as we know it. The problem is, in order to stop growing, you need to cum. The other problem was, sometimes you needed to cum numerous times. So some of these individuals were unable to until the pressure of their magically-filling balls became too much over and over again. Some people seem to be asymptomatic too, meaning they don’t grow at all, but their cum can infect other people. Some hospitals were even implementing milking machines to stop the growth as quickly as possible. The growth was seemingly permanent, too.

As I sat in disbelief in my bathroom back at home, I felt my body shaking. I wasn’t sure if it was from fear or some internal reaction. I was hoping I had caught it in time, but I knew that was far from the truth. I needed to get to a hospital. I stood up, grabbed my keys, and started to walk towards the door when I heard a slight gurgle. I looked down to find my bulge was swelling. I wasn’t particularly gifted down there before, coming in at around 4.5 inches, but I had to be 6 inches long now! I felt a knot tighten in my throat as I sprinted out the door. Could I make it to the hospital before I grew too big?

I practically dove into my car, jamming my keys into the ignition. The engine roared to life as I put the car into drive, noting how my sleeves looked slightly more filled out. I winced as I saw my bulge tighten. It felt and looked like I was hard, yet I was still soft. Already it was beginning to look impressive, and that was the last thing I wanted. The size of those that infected you typically translated directly into the sizes you would become. Surely I wouldn’t grow that big, though. Was that even possible? I slammed my feet onto the gas pedal as I veered out of the driveway.

The hospital was only a couple miles away, but it felt like it could have been hundreds. Only 15 seconds into my drive as I started to exit the neighborhood, I felt my chest begin to swell against my shirt. I used my other hand to trace the outline, feeling it slowly pull away from my torso. My heart was pounding, further circulating my contaminated blood through each of my limbs. Calling 911 was no use. There was a chance that by the time the ambulance arrived, I would be too big to be safely transported. Besides, I needed to get to a milking machine. The industrial grade ones at the hospital were known to stop growth in less than a minute. That was my best bet. Those who tried to jack themselves off were usually too overwhelmed with their own size to reach climax quickly.

The first light I hit was red. Shit! There was enough traffic intersecting that I couldn’t run it, but this was my body we were talking about here! I grunted as my clothes started to tighten around my frame. We were only a tenth of the way there, yet I seemed to have already grown over 50 pounds! My ass pushed backwards into my seat as I reclined my chair a bit further to allow for some more space. I could feel the cool air conditioning running along my midriff as my shirt rose higher on my body. Each of my..abs? I had abs already? Well..they were deepening. Already nicely toned, with each muscle rising from my core.

The light turned green, my feet automatically pressing on the gas as my toes cramped into the end of my shoes. I was growing taller now too, and it was getting faster! My balls felt like two oranges, and now that my thighs were straining my shorts to their limits, they were beginning to spill out of the leg holes as they pulled closer to my waist! My dick snapped the buttons off of them as it grew slowly out of my waistband, beginning to harden and throb as it reached up to my belly button.

“No!” I exclaimed. I was officially now 2/10 of the way to the hospital. I needed to go faster. I was only 5’ 10”, 160 pounds this morning. By now I must have been 6’, 250 pounds. I was looking positively jacked, but with a lengthening pornstar level cock that was approaching 10 inches in size!

I slouched down as I felt the growth get even faster. My sleeves tore as they inflated outwards, my biceps looking like they had been forged in iron as my triceps went for the gold medal. My shirt was now so small that it was like a crop top, shrink-wrapped around my pillow-like pecs, putting my entire lower body on display. My traps rose up my neck, pulling it even tighter as my back started to overflow the bounds of the seat. My seatbelt locked, trying to retract as its imprint started to sear into my body. I looked like I competed competitively in some of the largest tournaments on Earth!

3/10 of the way there.

My shoes ripped apart as I felt a few inches of height slam into me all at once, nearly shoving my head into the ceiling. My shorts burst off as my lower body all scaled with it. My thighs were like watermelons. My balls were closing in on cantaloupe size, nearly overflowing my seat as my rock-hard, leaking cock slid its way up to the bottom of my pecs. I wasn’t going to make it!

4/10 of the way there.

I felt my arms begin to press against the door as my space started to minimize. Trying to maximize it, I rolled down the window quickly, letting my left arm breath as air whipped around the car. Other cars drove past, people staring in awe as they quickly tried to get as far away from me.

Anyone’s eyes would be able to see me physically growing if they started for more than a second. I tried desperately to resist the temptations of my manhood, but the more size that pumped into me, the more aroused I was beginning to become. I grunted as I felt my seat belt tighten more and more against my quickly growing body, but when I went to try and unbuckle myself, I couldn’t reach it! My ass had grown so much that it was now practically underneath me. My own musculature was beginning to spread across the middle! I had to be one of the largest bodybuilders on Earth, coming in at 412 pounds and 6’ 6” in height. Well, at least before this virus started.

5/10 of the way.

I was halfway! That was a small victory in my book! It had only been a few minutes since I left home, and in that short amount of time, I had already grown over 260 pounds and was closing in on a foot of additional height!

SNAP!

The seatbelt and my shirt exploded off as my pecs surged, slamming into the steering wheel. It laid on the horn as I nearly lost control of the car. I moved my seat back as far as I could, but it didn’t make a difference. The space was almost made up for in growth no matter how much room I made. This was too much! I needed to stop growing!

My arms thickened to the likeness of propane tanks. My forearms started to look ludicrous as they plumped up to a similar degree. As a half a foot of height slammed into me, I felt my back launch into the ceiling of the car as I leaned down the most that I could. My traps were now level with my ears and were showing no signs of slowing down. I could barely get my feet off of the gas anymore, and I most certainly couldn’t use my mirrors!

I felt like I was piloting a body that wasn’t mine. A body that was now completely naked, and only becoming more grotesque. I could feel my new power, but I didn’t want it. It was only getting faster..

6/10.

My manhood surged again, causing my cock to wedge its way between my pecs and the steering wheel as it swelled to 2 ½ feet long. My balls were beginning to spill over the edges of my seat, now looking like medicine balls. I couldn’t even see them over my chest. With the newfound size of my rear, I was practically sitting across half of the car now, with my shoulder width taking up half of the passenger seat. I was so cramped that I wasn’t even confident I’d be able to get out anymore. If I got stuck here though, I’d be at the mercy of my body, and I couldn’t let that happen! I couldn’t..

7/10.

As if the universe hated me, my car started to sputter and groan. It was over 20 years old and had a lot of issues with stalling in the past, but this was at the worst time! I felt it begin to slow down as my acceleration became useless. My speed of 70mph quickly dwindled all the way down to a stopped car as I attempted to pull over. At this rate, I could barely turn the wheel with all the friction of my limbs in such a tiny space. I was only a minute’s drive from the hospital, yet the worst case scenario had happened. Perhaps all the extra weight was too much for it.

8/10.

This seemed like a suitable time to call. I was so close that perhaps they could come and get me. I squeezed my way out of the car as best as I could as the door burst off of its hinges. The metal frame creaked as I somehow squeezed all 703 pounds of muscle out of the car. Standing up, I reached up to an astounding 7’ 2 inches tall. My entire body settled as I felt my balls pull on my groin, dropping to my knees as my erect cock bobbed nearly 3 feet in front of me. Totally naked, I was a sight to see. I scrambled to grab my phone, before I saw its smashed outline on my seat.

I sighed, before looking down the road. I could see the red hospital sign in the distance. I just needed to walk close to half a mile. Just a little bit further.

As I started walking, I felt my growth accelerate once more, knowing I was about to be in a fight for size unlike any other.

It’d already felt like I had been fighting this virus for hours, when in fact I had only started growing in the last couple minutes. In that short amount of time, however, everything had changed. Here I was growing faster and faster, struggling to reach the hospital as I started to press beyond the size of a lot of hypers.

Every step was like an entirely new experience as I felt a heavier amount of bulk settle onto my frame. I could tell that I was already beginning to pass 750 pounds, and I had only just gotten a few car-lengths away from where I had parked! I lifted an arm up, just to see the impossible.

It was thickening so quickly that I could physically see it expanding with my own eyes, and at a worrying rate, too. My cock was now easily level with my collarbone as gravity started to take it over. It bobbed away from me at a 45 degree angle as it pressed beyond 4 feet long. My own balls continued to descend, reaching the top of my calves now as I struggled not to trip over them. I was leaking a steady stream of precum now, and as much as I wanted to stop and worship my own mass from the sheer lust my body was sending to my brain, I had to resist!

“Help!” I yelled, clasping my hands over my mouth as a deep bassy pounded outwards from my vocal chords. I didn’t even sound like me anymore! The call for help fell upon deaf ears, however, as it went unanswered. Not even a single car was on this road. People were so afraid of catching the virus that most people were still in lockdown. Just to avoid people like me.

Another surge rippled through me, causing my arms to instantly double in size! Yes, double! From the width of propane tanks to the size of an entire grill-top! My pecs followed, punching out to the size of the trashcans I rolled out to the curb every week! My delicious pecs pulled my legs forward so heavily that I lost my balance, forcing my legs downwards as my knees cracked the asphalt below. The crack splintered outwards as my legs then doubled, now just as wide as my shoulders. The cool sensation of my balls slapping onto the ground caused a blanket of euphoria to shoot through my dick. A large stream of cum shot over 10 feet as I gasped for relief.

Panic flooded in my chest as I tried to get up off of my knees, but couldn’t! Everything else was filling out to match the rest of me, such as my abs molding into a 10-pack, and my back growing wider than a table. If it hadn’t been for my increasing height, I’m not sure I would have ever moved again.

The spiderwebbed asphalt shrunk away from me as I realized my height was pressing beyond 8 feet now! The issue is that I was gaining muscle at a far faster rate than height, which only meant one thing if you could put the math together.

“Why won’t..it..stop!” I groaned as I started to walk again. My balls were now level with my calves as opposed to just reaching them now, but I felt them dropping towards my ankles. In just a few seconds, they would be there. My own phallus was now nearly 6 feet away from me and just mere inches off of the ground. Globs of precum that could fill entire buckets were dispensing onto the ground. If you wanted a breadtrail from my car to the hospital, this was definitely an interesting method to do so.

Most people’s growth stopped by now, even if they hadn’t cum, so why was I still growing? I know the man in the supermarket that infected me was a bit bigger than this, but was that really my reality? Surely I wouldn’t get bigger, right?

9/10 of the way there!

At this point I was beyond 2,000 pounds. Size was absorbing onto me so quickly, yet I was basically on the driveway at this point! Only a few house-lengths away and I could get help, I could get-

Suddenly, it all went out of control.

My balls lurched with so much energy that they smashed into the ground in an instant, now swelling multiple inches per second. My cock followed suit, officially touching the ground before sliding in front of me. It was erect as a plank of wood, yet now nearly as big as the car I had just been in two minutes ago.

“Mmmf—stop!” I said through gritted teeth as I slid forward another 10 feet. So close, yet so far! Every step was painstaking, as my body contorted and expanded so fast. My traps swelled beyond my head as my pecs forced my head upwards, blocking my view of the hospital doors. Each pec was now larger than entire recliners. My arms kept awkwardly catching on my body as everything crammed into everything with so much intensity that I was having trouble making basic movements. One arm alone was like an entire couch!

As my legs each exploded with thick, hot, juicy muscles I knew it was over. Any gap that was between them filled up completely as I felt their movement become restricted immediately. I toppled backwards as my ass caught up, each beautiful sphere combined made a width as large as a full-sized bed! The boom was deafening as my 10,000-pound, 12-foot tall body planted there. I was now as wide as the entire road basically, nearly double in width than my own height! My own cock pointed straight up into the air by over 20 feet now as my balls pressed beyond my legs.

“Aghrrrrffffffff—!” I let out a frustrated moan of horniness as I helplessly tried to cum, but it was no use. My arms were completely incapable of helping either, seeing as I was so close to immobility that I could only move a little bit. My voice muffled against my own mass, suppressing my cries for help. I wouldn’t stop growing until I came, but I wasn’t even able to fit into a milking machine anymore! I couldn’t even reach my manhood over my own size! Especially seeing as my arms were forced almost at a 90-degree angle, and immobility had almost completely taken me over! I cringed as my cock climbed another foot and my balls spread out even wider. The trek to the hospital was for nothing! I was now easily the biggest human ever infected, yet I was STILL growing!

As gallons of precum flowed down my telephone-pole sized shaft and onto my glorious, naked body, I tried everything I could to get off as my growth continued to accelerate. Hundreds of pounds per minute quickly turned into thousands as my own musculature and hyper-morphed status spread into that of an overexaggerated statuesque appearance that you’d only find in someone’s deepest fantasies. Would I stop growing? Would help arrive? That and a million other questions flooded my mind as permanent growth started to take over every part of me that I had ever known. As the virus continued to mutate, there was no saying just how big I was about to become.

I groaned as my deep, rumbling voice vibrated through my own feet. I tried to roll over. To get back on my feet. To do anything! But I was like a turtle on its back. Completely helpless, yet needing desperately to be helped. In my current state, both my pecs and traps were taller than my own head, my arms and my legs were almost completely immobilized in a starfish position, and my cock was looming higher and higher with every moment.

Cum helplessly poured back down onto my body as my cock grew to 30 feet in length. My balls were larger than smart cars now, meaning my own legs were starting to look almost smaller in comparison to them.

Frustration continued to build. I was only 200 feet from the front door! How was I going to get off now? How do I make the growth end?? My overinflated hips bobbed up and down with the gushes of cum that teased my cockhead for release, causing me to main as my face grew hotter.

How big was I now? Clearly I was becoming wider than the road! I could feel the grass on the edges lick at my muscles as my eyes craned upwards to see what I could around me. My own upper body was higher than my eyes by an entire foot. Maybe more. Every moment that passed only ceased to make me more immobile. I needed to get someone’s attention.

“Help! I can’t..stop..growing!” I roared, feeling another growth spurt crash into me. Suddenly it was like my growth doubled in speed, power, and pleasure! The asphalt cracked into a thousand pieces underneath me as I effortlessly crossed 30,000 pounds. All of that on a 10 foot frame. I was growing taller more from my own muscles at this point than an actual measurement on my legs! My traps had to be pushing 12 feet!

At this point, I actually started to release pre-cum at an extraordinary rate. Full on ropes of jizz, just spraying more than double my height into the air, but still not having reached a climax. The lawn started to paint itself as I feverishly grew, throbbing larger and larger with every passing second.

“No, please! I need to stop!” I pleaded helplessly as my pecs and traps surged again, replicating dinner tables in size now! My arms, which I had already thought were enormous, continued their reign of extremity, so much so that I could feel my forearms begin to overshroud my hands, and my calves overbear my feet!

I wasn’t just going to be unable to move a little bit. I was going to become too big to move anything! Even if that meant my hands and feet! Hell, even my fingers and toes! I squirmed to do anything, but found myself quickly exhausted as muscled pummeled me into the surrounding crater.

40,000 pounds.

It had only been a minute since I had hit 30,000 pounds. How had it gone wrong so fast? My own cock wasn’t lagging behind either. I felt it elevate, just punching higher every second. 25 feet tall. 30 feet tall. 40 feet tall. I found myself in a longggggg moan as it pulled itself further from my body, rivaling the height of the hospital now as my balls exceeded my legs by multiple times now.

64,000 pounds.

Where was the help! Didn’t anybody notice the commotion going on? I tried to move once more, but found my flexing muscles only adding to my growing size. My heart was pounding so fast that I felt light headed, but yet more alive than ever all at once. Even my own forearms were bigger than my car once was. My ass alone could fill a swimming pool, and that was if my lats didn’t prevent me from trying. A 10-pack of abs wasn’t just destined, but confirmed. Each bump is like a dinner plate.

The canyon that my own upper body was making around my head was historic. I couldn’t see over them if I wanted to! They were making a bowl of size around me that muffled my cries for help..until.

It stopped.

The growth stopped.

I gasped, holding as still as I could as my body settled. Once the creaking ended, it was all quiet except for the sound of my own heavy breathing and dripping precum. Was it over? Was it finally done? It didn’t feel like I had orgasmed, but maybe I was so preoccupied with stopping it that I had and didn’t notic—

BOOM!!

Suddenly, everything was expanding so quickly and so chaotically that my brain had trouble processing it. In a mere second, I fucking doubled in size, or more. In every way! My traps and pecs grew larger than train cars. My arms exploded to the size of entire rooms. My legs and enormous ass, which I thought were already elephantic, could now fill a backyard!

All I could do was gasp as my dick slingshot skyward as it became a beacon in its own right, over 100 feet long as gravity started to weigh it down. It crashed into the landscape beside the hospital, thicker than the entire road was now as it started to elongate down the expanse of grass beside it. My own balls could genuinely be described as water towers now as each one filled with so much cum I wasn’t sure they would ever empty.

And I thought I was immobile before.

“Oh. Oh god, no! Not more!” I screamed in a mix of horror and pleasure.

My hands and feet were swallowed in an instant. Any room I thought I had left wasn’t just overtaken, but overloaded to the furthest degree of what I thought was possible. I couldn’t even move my fingers anymore. I couldn’t twitch my arms. I couldn’t clench my feet. Any flex just sent more shivers into my cock, which was spewing precum so badly now that it created entire streams that began to run off onto the highway nearby.

If there was one upside to any of this, it got the attention of the hospital. Workers began to run out with equipment to stop the endless feat of size, but no one was prepared for something this out of control. The largest man hadn’t even exceeded a few thousands pounds before me, and now they were dealing with a 400,000+ pound, 20 foot tall monstrosity with a cock that their machines could never hope to fix. But they had to try.

I felt a mixture of relief and humiliation fill my soul as I could hear the work effort going on outside of my own muscles. My own head hadn’t scaled one bit with my mass, so I felt comparatively small. How could this much muscle fit on such a small frame? Then again, how could growth like this happen in the first place?

The hazmat-wearing workers threw an enormous padded-silicone rope around the end of my cock as my own precum worked as lube for what happened next. A working force of 10 people on each side thrust it up and down the enormous length of my cock as pleasure spiked into my body like none other. I could feel my muscles spasming, desperate for size, but also desperate for release all at once. All while my balls kept increasing at about 10 feet per minute.

The road was hopelessly lost under me now. I was actually beginning to encroach on the actual entrance of the hospital now. All while I grew, an effort was underway to evacuate the hospital. I could hear the publicity of my situation expand as ambulance, workers, and a much larger workforce overall arrived on scene to stop the catastrophe.

More ropes covered my expanse as one group even went as far as to make a moving ring that could slide up and down me for added convenience with large pull-strings on either side for them to use.

I could feel the orgasm sensation build up more than it ever had before. If I could rock my hips, they would be rocking like a boat during a storm. My breathing picked up pace. My face went flush. My entire musculature went tingly as I tried to think of the hottest things that I could think of to quicken the process. I didn’t even want to think about what would happen if the growth stopped while I was already this big, but it was better than being any bigger!

But it wasn’t over yet.

All at once, another major surge happened. This time exceeding the first one with ease. An audible kaboom exploded outwards as my relief was suddenly sucked back into me. The unidentifiable hill of muscle that I was, became an unidentifiable subdivision of muscle.

KABOOM!!

Right on the edge of my orgasm, all of the momentum became lost as the workers ropes all wrapped around my manhood, tightening to the max as it grew.

And grew.

And grew.

The workers found the ropes yanked from their hands as they ran away in fear. The ropes that were already wrapped around me started to work as a cock ring, restricting blood flow and making it harder to cum, which also made me even hornier. I could feel it thickening, lengthening, and becoming more restricted with every inch of added flesh. 120 feet quickly became 150 feet, which passed 200 feet. Higher and higher it spread, beginning to push aside tries and benches as it reached the other end of the yard. It was starting to outsize my body as my own balls started to swell underneath me. Maybe it was because the base root of this virus was pleasure, but it seemed to favor these assets the most, and now it just couldn’t stop flooding more beautiful size into them. Now that I wanted any of it.

“Fuckk…too…big.” I gasped. My voice was booming now, and that was before my muscles hit their spike. Just as everyone got out of range, the rest of me tried feverishly to catch up. I felt my back sink over 10 feet into the Earth as my pecs and traps swelled from train-car sizes to city block sizes! I thought it was the Earth, actually. It was my own balls, pooling underneath me as their soft texture started to rise me up on a pedestal of masculinity. My own arms alone could fill the interior of an olympic swimming pool building! My ass rose up even higher on my ever-inflating balls while my back worked with my shoulders to broaden beyond belief.

The hospital found itself crumbling as my body expanded into it—and then past it. I tried to cum. I tried so badly. But now there was no hope of stopping it. At this point, though, would it have mattered? I had to be over 50 feet tall in mass alone now, with a head buried so deep that I could barely see the night sky at the top of my colossal pecs and traps. Based off feeling alone, my own hands and feet were completely overwhelmed by the rest of me, meaning that no matter what happened now, I wouldn’t be able to move anyways if this ended. Nobody had ever shrunk from this virus before. Nobody.

So what was the point in trying anymore, anyways? The pleasure was so overwhelming and so euphoric that it felt kind of pointless to try and live a normal life anyways. Especially when I could become…bigger.

I shook my head at the thought. What the hell was I thinking? I need to stop this! To-

My cock continued onwards, crashing over the highway and through the terrain behind it like a tornado as entire rivers worth of cum started to flow down the streets. All while my new cock ring kept pushing me closer and closer to an edge I wasn’t reaching.

It was over 400 feet long now, and showing no signs of slowing down. My balls made a barrier of flesh around me now, lifting me up more than 10 feet off the ground as it started to become faster and faster.

A life at this size would be lonely. Images of being massive: Bigger. More immobile. More hung all flashed in my mind like a slideshow fantasy as my brain started to lose its sense of rationality to my 300 foot-in-diameter cum factories.

The incredible thing is that my growth wasn’t slowing down like it had before. Tens of thousands of pounds were adding onto me every single second, and it was getting faster. And I wanted to be bigger. I didn’t want to be alone, either. I wanted everyone that saw me to join me, so that I wouldn’t be alone in all this humiliation and size. If I had to be big, I wanted everyone to be big.

The moment that thought entered my mind, something changed deep inside of me. Everything started to engorge faster. My cum production ramped up. My testosterone increased. My height continued to shoot up. Most importantly, my cock and balls went into overdrive.

Moan after moan spilled from my mouth, sending a deep thunderous echo throughout the city like a warning as..

SURGE!

My cock doubled in thickness and length again, exploding out to over 1,000 feet! My cockhead alone was the size of the hospital now. My balls were starting to become seriously difficult to comprehend, but they expanded in sync with my manhood meaning it had to be somewhat close to that many feet in size too.

My muscles were fighting for space so erratically on my million pound frame that the ground around me was turning into a genuine Earthquake as I was pulled in every direction. The light above me went out completely as my own traps and pecs squashed together like the rest of me. Yet, I found myself more aware than ever of every sensation. Touch far beyond any other. The bumps of empty houses, cars, and buildings as I began to expand beyond the hospital’s bounds. The water of a nearby lake, pond, or river as a muscle slipped into it, overflowing instantly. The minor sting of a suppression dart as the military, no doubt, tried to stop what was happening. But I had no control. I hadn’t from the moment I was infected in the supermarket. It felt as if I was being turned against for something I had no control over. And now it was their turn to know what it felt like.

“You’re all going to join me!” I grunted with a muffled tone from deep within as suddenly—

I started cumming. I was cumming!! Truly, effortlessly cumming. I could feel my balls tense and release underneath me over and over again as I started to shoot over a mile from my 1,500 foot cock. It didn’t change my mindset, however. I knew it deep inside from the moment I passed 20,000 pounds. I was too big. This was a mutation that didn’t end with the simple act of cumming. Maybe I was chosen, or maybe I was just unlucky, but I had a purpose now. Images of humanity joining me in my fight for size flashed in my head, and I felt satisfied knowing what was to come.

And so I sat, on my back, ascending on my football-stadium-sized balls as my cock expanded at over 100 feet per second, crossing 2,000, and then 3,000 feet with no sweat broken, all while launching cum an incredible distance! My own muscles weren’t far behind, either. Although I was more cock and balls than man, my body was in a constant state of seizing and swelling with 100,000 pounds of sweet bliss per second.

The tallest buildings in the region would be completely toppled by my body now, especially with pecs as large as colosseums. Arms as large as neighborhoods. Looking up at my chest and traps above was like walking to a cliff-side and looking for the top. It was entirely gone. The world watched as this incalculable, indeterminable mound of flesh with no discernible feature aside from a mile-long cock and balls just cumming lakes worth of seed endlessly now.

Anyone caught in the cum-slide would grow, too. The simplest bit of contact. A slip on the grass. A drop on your arm. The inhalant of particles in the air. Any males would soon find what happened to me happening to them, and now I wanted to see humanity turn into muscle bound, immobile, macro, cumming giants like I was to spare me from the humiliation of being alone, and I knew it was time. No matter how big anyone else got, I would be the biggest now. I could feel it in my very soul. I was the catalyst, and they are the result. This was an outcome that the virus made happen no matter what.

This was predetermined from the moment I was infected. It wanted me to make my way to the city. It wanted me to grow too big to take care of myself. It held me off on purpose, and now all it wanted was to make me orgasm until every available person it could find would be infected. And who was I to stop it?

As my growth accelerated again, I felt myself sink the pleasure as my cock and balls did all the work for me.
