Prologue

It had only been snowing a few hours, and already the houses were buried in a thick white blanket. One of the neighbors was braving the snow to hang up his Christmas lights. Puffs of white were rising from every chimney, and the air smelled like wood smoke. It was a charming little suburban street, straight from central casting.

Down on the sidewalk, invisible to any human eye, were two little men, hardly taller than a grown man’s index finger. They were trying to walk, but the layer of snow was giving them a hard time.

“Snow again. It’s the same thing every year,” one of the gnomes complained in a high voice. He snapped his fingers, and the two drifted upward to hover a few inches above the frozen carpet. “Aha! It’s right over here. Wait till you see—he’s perfect!”

The name on the mailbox said Max Grant.

The gnome snapped his fingers again, and they landed on the windowsill of the quiet house. Frostwork covered the glass, but with a little scrubbing, they were able to see its living room, dimly illuminated by some small lamps and a few lit candles.

As they watched, a man came up from the basement. He was wearing workout clothes, and his skin glistened in the lamplight. Through the closed window, the gnomes could just make out his voice.

“Damn, forgot the candles…again. Guess I’m lucky to be alive.”

The gnome that hadn’t yet spoken piped up. “Are you sure he’s right for us? Remember last year? That was a disaster.”

“Don’t remind me. This time I’m sure. Just look. He’s perfect.”

Max pulled his sweaty shirt off, revealing a sculpted torso. He stroked the flat of his hand down the chiseled surface of his six-pack. He threw the sweaty shirt into the washing machine and went off to make a snack.

“Just having abs and working out twice a week doesn’t make him a good candidate,” the second gnome grumbled.

“This won’t be like last year, I promise! He wants it.”

“Whatever. I think we’re wasting our time.”

He turned to go, but the other gnome grabbed his little hand to hold him back.

“Look again. He’s perfect.”

The gnome peered through the window once more. Max was now doing poses in front of the big mirror in his living room. He was smiling, admiring the definition in his body and what seemed to be some recent gains. He was down to his underwear now, and the two little men could see his hard-on through his underpants. Finally, he stepped away from the mirror to gulp down a protein shake, giving his boner a few jerks as he chugged.

“Okay, fine. We can use him. I can see he’ll get bigger than the guy last year, at least.”

“That’s what I’ve been saying! He’s perfect—the most promising candidate in years!”

“Okay, calm down. I can see he’s got a lot of energy, but we haven’t even started yet.”

“Oh, yes! Let’s get to work.”

In unison, they clapped their hands and reappeared on the doorstep of Max’s house.

“Let’s just start slow and see how he reacts.”

The other nodded. The two chanted something in a strange tongue, and out of thin air, a wrapped gift box with a red ribbon crystallized out of nothing. They snapped their fingers, and the house’s doorbell rang.

“Showtime,” the gnomes said, and they vanished.

 

December 1st

When Max opened the door, no one was there. He looked left and right—not for too long, he wasn’t wearing clothes, and it was freezing cold out—but there wasn’t a soul out there. Only then did he notice the present waiting at his feet.

“Little early for Christmas, isn’t it?” he asked the empty air. But he brought it in anyway. Back inside, he read the card.

Merry Christmas to our big guy! Enjoy!—Santa’s little helpers.

“Huh.” He opened the box, which contained nothing but a lot of red velvet...and a ring. It was golden and covered in etched ornamentation. The inside of the band was embossed with the silhouette of a distinguished-looking man.

“Who sent this?” Max said.

And then he tried it on.

As the ring brushed past his second knuckle, Max noticed a golden shimmer at the edge of his vision. In a flash, the ring and the box were gone. The air seemed to become translucent for a second, as though he were surrounded by millions of crystals, abruptly fading into nothing. Max spun around, gasping for breath.

“What the fuck?! Where…where did it go?”

His eyes wandered back to the protein shake he’d just had. Suddenly he felt dehydrated...and incredibly hungry.

“Fuck. Guess it’s time to cut back on the injections. And I have to eat something!”

He wandered back to the kitchen. In the right light, you could have just made out the emblem on his left ring finger where the ring had been seconds before.

The gnomes were back on the kitchen windowsill.

“Did it work?”

“Yeah, he put it on.”

“Yes! That’s an excellent sign.” He paused. “Not the brightest bulb on the tree, is he?”

“No. But he’ll be the biggest in no time.”

The other giggled. “It looks like he’s bigger already!”

Inside, Max was busy stuffing himself with the leftovers from the fridge. He had set a chair right in front of the door and seemed to be devouring everything he could get his hands on.

“Look at him grow!” the little magician said.

But Max wasn’t done. Swallowing, burping, and caressing his bulge, he continued to gorge himself for at least an hour. Night had fallen on the street by the time he stopped.

“Mmm, feels so good! What a feast!”

Max went back into the living room where a glimpse of his half-naked form in the mirror stopped him in his tracks. His lifting regimen of the last few months was finally paying off—in spades!

He had just eaten enough for four, but his belly remained as flat as ever. His pecs, on the other hand, looked rounder and smoother. His shoulders seemed to be a little broader, and his upper arms looked like they’d gained a full inch in circumference. With a broad smile, he ran to his bathroom and jumped onto the scale.

“I’m up 30 pounds?! There’s no way…”

But there was no arguing with the number: 222!

“Nice! I’m getting huge, finally!”

The thought alone was enough to give him a hard-on. One look at his now thicker thighs, and he realized with a sudden surge that he needed to jerk off right then. He tore off his underwear, exposing a tight 5-incher that was radiating with sexual heat. His balls looked full and suddenly much better than average-sized.

“Mmm, big…so much bigger. More, mm, yes, more!” Max whispered to his image in the mirror before he came—a lot. After ten spurts, his reflection was drenched.

“Fuck, that was fast!”

The gnomes, outside of the bathroom window, were impressed.

“Okay, you were right,” the second admitted. “He might be the best candidate we’ve ever found.”

“Right? That load? The magic hasn’t even reached his balls yet, and he’s already a heavy cummer!”

“Did you see the way he looked at himself in the mirror? This is going to be too easy.”

“Now, all we have to do is wait.”

They turned their expectant gazes back inside. Max was already getting ready for a second round.

 

December 3rd

When Max woke up two days later, he felt changed. The first thing he noticed was the energy flooding through his body in waves. He felt strong enough to conquer the world!

The daily posing session, the inspection of his face and body, was taking longer every morning. Ever since he’d started putting on weight, it had been hard to keep his hands off his new mass.

Everyone else in his life seemed to have the same problem. Whenever he was on the train to work, there was no getting away from the longing gazes at his pecs, and even the occasional hand discreetly brushing his ass. Max had yet to buy clothes that fit his new frame, and he enjoyed teasing them a little bit, knowing everything he wore clung tightly to his meatier form.

What was even crazier was that the changes kept coming. Today, he noticed even his face seemed more attractive, more masculine than a few days before. He traced the line of his jaw with his fingers and felt the bone structure, more prominent and angular than he was used to. The short beard he sported was denser and darker. His jaw has broadened, squaring off his face. And under his wider, thicker brows, his eyes were radiant with power—enough that he stopped the inventory of his body just to gaze at himself. He was stunning!

When he got out of the shower, his hair seemed to be perfectly styled already without any effort on his part. As he ran his hands through it, he realized how much bigger his hands seemed to be today. Max looked down—his feet, too. Definitely closer to 12s than 11s now.

Instead of asking himself what was happening to him, he just gave himself a cocky wink, threw a shirt on, and was out the door.

All eyes on the train were on him. Everything on him, especially his shoes, was tighter than ever today, but if anything this only seemed to increase the pleasure everyone took in looking at him. Their reactions gave him even more confidence in his new skin.

When he arrived at the bakery, the compliments started to flow. His co-workers couldn’t seem to help themselves.

“The new haircut suits you, Max!”

“Been bulking up, have you?”

“I’ve said it before, but your hands are made for this job! You can knead twice as much dough as I can.”

He became aware that every customer coming in for pastries or a pie was following him with their gazes. Eyes that had been glued to smartphone screens suddenly were only interested in him, his face, his pecs in the tight shirt. One man admired so long that he forgot what he’d come in for. And most impressed of all were the two guys in red sweaters who almost looked like twins. Something about faces looked a little strange (almost as if they’d been gnomes in a previous life), but they were no less entranced than anyone else.

Max was enjoying the newfound power he seemed to have over people. It was only a matter of time before he would be ready to start putting it to use.

 

December 5th

“He’s waking up! He’s waking up!” The gnome on the windowsill cried. “And just look at his progress! Remarkable.”

His companion pressed his face to the window and frowned. “These last two days it seems like all the magic is accumulating in his pecs.”

“It’s only been a few days, and he’s almost bigger than last year’s candidate already!”

Max was slowly waking up from a weird dream. He stretched his arms overhead and groaned loudly. When he relaxed, he became aware of a strange weight pressing down on his chest.

“Oh, fuck,” he whispered. “It wasn’t just a dream…”

He jumped out of bed and bolted for the bathroom. His steps were oddly heavy, making him realize just how much extra mass he was carrying.

“God damn. Look at this rack!”

The gnomes had disguised themselves as expensive-looking perfumes on the top shelf above the mirror. Somehow, you could feel that even their mouths were wide open.

Max’s chest had added at least a dozen pounds of muscle mass overnight. His two hairy melons were now suspended over a flat six-pack, demanding so much space that they formed a broad overhang that only disappeared when he flexed them. His nipples were big as thimbles, the cherries on top of a sumptuous dessert. He cupped them with his fingers, fascinated by how sensitive they felt in his big hands.

“Holy shit. These puppies are heavy.”

He had to see that massive chest in motion. Grinning, he began to pose in front of the mirror. When he changed positions, his titanic jugs actually jiggled. His cock immediately started to harden.

“Those things will be visible through every shirt he owns,” whispered one of the perfume bottles.

“Better and better!” whispered the other.

Max had gone to his drawer and was pulling on the smallest, tightest shirt he could find. It couldn’t even cover his abs, and it almost looked like he’d put corks under his shirt where his nipples should have been.

“Guess these puppies are too big to hide now.” He had to laugh as he grabbed them with both hands and massaged them aggressively.

Before he left for work, he stepped on the scale: 252 pounds. His upper body had put on 30 pounds of mass with no effort at all. His 5-inch hard-on wouldn’t be coming down anytime soon, that was for sure.

Max had a hard time focusing on work that day. Every time he looked down, his enormous pectoralis muscles were right there. He had to touch them every few minutes to make sure they were real and as heavy as he remembered. He shouldn’t have worn a black shirt, he realized—the prominent flour prints were evidence of how often he’d been grabbing them.

His co-workers, their eyes glued to his newly-enhanced rack, kept asking if everything was all right. Curiously, none of them were curious about what had happened with his body. Their minds were busy envisioning other scenarios.

The stares he earned at the gym that night were even more brazen than the ones he got at work.

After an hour of hard lifting, he hit the locker room for a well-earned shower. As he slowly soaped himself up, the weight of his new muscles felt so good that an involuntary moan left his throat.

“Fuck…”

His fingers found his nipples and went to work. His erection pulsed. It had been a constant companion throughout the day, and thinking about his size now made it even harder. He didn’t even mind the guys lurking in the background, watching as he jerked his chest under the gym showers.

He came without touching his cock once. The enhanced sensation in his overgrown chest and big nipples was all it took. He painted the shower wall in 10 big shots, and let the running water clean up after him.

On the way back to his locker, he let his still-rock-hard schlong swing free for everyone to appreciate—it wasn’t the longest in the locker room, but he was starting to get the sense that that, too, might be changing for the better soon.

“Holy fuck…Max? Is that you?”

Max turned around and to see Jonas, an old lifting buddy he hadn’t seen in a while.

“Jonas! Looking good, man!”

“Jesus, look who’s talking! Man! Look at those pecs!”

The gnomes were sitting on the lamps high above their heads. With a gesture, they were able to observe Max’s thoughts.

“He’s happy to see his friend again,” the first one said.

“He’s horny for him,” the other clarified.

“Better and better.”

 

December 7th

December seventh was the first day Max woke up without noticing any changes in his body at all. He turned and turned in front of the mirror, examining his reflection, but everything looked exactly the same as yesterday.

Was it already over? Had he been blessed with an enormous chest and that was it?

“I wanted to get so much bigger,” he said, a little sad.

But the iridescent symbol the ring had left on his finger was still there. Peeking out from the inside of the sock drawer, one of the gnomes nudged the other. “Why hasn’t he changed yet?”

“The change is building inside him but it hasn’t manifested yet. Sometimes it needs a catalyst. We should help him. Let’s make him horny!”

Max arrived at the bakery, threw on his apron (the straps digging uncomfortably into his immense pecs), and started to decorate some cakes. When the little bell on the front door rang, Max hurried to the front room, but what he saw there froze him in place.

One of the gnomes had created an illusion around himself, making it look like a six-and-a-half-foot man had just squeezed himself into the little bakery. He looked as big as a bull, bulging muscles making him almost as wide as he was tall. He sported a nose ring and a thick dark beard. A delicious, musky scent preceded him as he walked toward the counter. Max noticed his flannel shirt was only halfway buttoned, and the tight leather jacket he wore over it made him appear even more massive than he already was.

The other gnome, watching the scene from the top shelf, watched Max’s heart rate starting to rise.

The giant customer walked right up to the edge of Max’s counter. He was so tall that the bulge jutting forward from his pants swelled right over the edge of the glass countertop. He leaned in as he spoke, until his entire package was basically resting on the counter.

“Hey there, kiddo,” he said. His deep voice seemed to rattle the walls of the small space.

“How…how can I help you?”

“I was looking for the post office, but I must have got the wrong address. It’s not here, is it?”

Max started to sweat, staring at the hairy cleavage rippling under the man’s shirt.

“No, it’s just a quarter mile down the road. You can’t miss it.”

“Perfect. Got to get those Christmas packages out!” he boomed. His bulge retreated as he dragged it back off the counter. “Thanks, man. Maybe I’ll see you around. And happy holidays!”

As soon as the customer was gone, Max ran to the door and locked it. He flipped the OPEN sign around and fled to the back of the shop.

Luckily, he had the place to himself that morning.

He fumbled to open his pants—and a way bigger package than usual tumbled out. Max stared.

Silently, the gnomes appeared on top of a bag of sugar to watch the transformation.

“We did it!” they whispered to each other.

“Fuck! My cock! It’s huge!” Max roared.

His former 4-incher was beginning to swell in his briefs. But it didn’t stop—it grew and grew, as though someone were inflating it with an air hose.

“Yes! Bigger! Bigger!” he cried, even though the snake between his legs was already reaching anaconda status. Max was now pushing 10 inches, still soft, but he was lusting for more!

He pulled off his shirt and underwear. His penis hadn’t stopped growing, swelling longer and thicker. Max could actually hear his skin stretching, trying to accommodate his new size. It didn’t stop until just after he’d passed the 13-inch mark, longer and wider than the rolling pin on the flour-sprinkled countertop.

Max pushed his hips forward, letting his enormous cock stand up proudly. He rotated his torso, swinging his cock until it slapped against his muscular thighs.

“Fuck! I’m finally hung like a horse! Even more than that! And I’m horny!”

He pressed his cock flat against his six-pack—his cock now grazed the bottom of each of his over-inflated pecs! He flexed his glutes and his cock actually leaped up to burrow itself in between them.

“I can fuck my own pecs…holy shit! This is incredible.”

From a bowl nearby, Max grabbed a big lump of dough that had been rising and slammed it into the floury countertop. The mass was warm and smooth, almost ready to be shaped into bread and buns. Max had a different idea.

“Is he going to…” one of the gnomes whispered.

“Yes.”

Max got in position and his cock slipped easily into the warm dough. A moan escaped his throat. Immediately, he began ramming his monstrous schlong into the center of the thick mass.

“FUCK! It’s so sensitive! This feels amazing.”

His full chest twitched with every thrust of his hips. He held the dough down with one hand while groping his pecs with the other. Bigger, I wanna get so much bigger, he thought. Come on—give me more mass, more size, more everything!

When he came, the gnomes could actually see the bulge of cum forming inside the mass of dough.

It took Max a while to calm down. He felt like he’d been struck by lightning. Slowly, he slid his cock out of the mass of dough, sticky and still spraying jets of cum.

“So much fucking cum. It’s everywhere. Fuck, I have to clean up before anyone else gets here.”

When he put his underwear back on, he got so distracted he almost forgot about the cleanup. The majestic bulge his soft 12-incher created was just too much. Out of the corner of his eye, he caught a glimpse of his reflection in the metal fridge door, a svelte silhouette with an extremely prominent bulge.

“Shit. I have to come again.”

Seconds later, he was naked again, down on the floor with the bags of flour. He pulled his legs in close to his body and bent down a little. His cock slipped into his mouth. It tasted like fresh bread.

It took three more orgasms before he could focus on work again.

 

December 9th

On the ninth day, Max woke up with a smile on his face. This time he immediately knew what had changed overnight—he could feel its weight on his chest—and even on his face!

“Holy hell, look at this monster!” he whispered to himself, wrapping both his huge hands around it. To his delight, the juggernaut between his legs had grown bigger still. It was way past 12 inches now: the tip of his magnificent length now reached all the way up to his chin. One stroke, and his lips were bathed in precum.

“Now this is a real man’s cock! Look at the size of it—it’s a fucking tree trunk between my legs! “

The two gnomes, watching from on top of the curtains, were impressed. Now over 18 inches long and thicker than a two-liter bottle of soda, Max’s gigantic hard dick was like a warm, heavy animal sitting on his chest.

The first steps out of bed were a challenge. Max almost tripped and fell over adjusting to his new forward center of gravity. His cock was big enough that you could actually hear it swinging through the air as he left the bed. He was speechless when he arrived in front of his bathroom mirror.

He had been blessed with the body of a god. He was actually salivating looking at himself, drooling a little onto his big muscle tits. It took both hands to lift his cock up and hoist it over the edge of the sink. His softball-sized cock head flared bigger as he touched it.

He flexed every muscle in his body for the mirror, laughing wildly.

“This is so good! I can’t wait for the day after tomorrow! How much bigger will I be then?! This is so hot!”

Max flexed his cock and it rose up all on its own, the head rising to his face without him having to touch it. He suckled on his cock for a while, wedging it tightly between his enormous pecs. A little twist on his nipples and pre-come flooded his mouth. Meanwhile, his other hand found his ball sack with its egg-sized nuts and squeezed it in anticipation.

“I hope you’ll be bigger too, soon! A lot bigger!”

The gnomes exchanged a devilish look. They knew where the growth was headed next.

Max was using most of his body to jerk himself off now. He bit his lower lip as his penis stretched bigger still.

“I wanna drown this place in cum so bad!”

Max couldn’t look away. His own reflection was the hottest thing he had ever seen. To come even faster, he imagined his balls swelling even bigger and hanging even lower. He fantasized about carrying around two basketball-sized orbs, each churning with gallons of cum.

He sealed his lips around the slit of his cockhead and came directly into his own hungry mouth.

When it was over he leaned over the sink, reeling. Sweat dripped off his forehead as he recovered from the epic orgasm. His cock had shrunk down to its soft state, but the head was still dangling heavily between his calves.

“Focusing on work will be kinda tricky today. And maybe always.”

But Max had never been happier in his life. The anticipation of possibly getting even bigger seemed to radiate off his body, filling the whole room with a magic glow. He strutted over to the shower to wash the rest of the cum off his pec shelf.

Max went to the gym that evening, making sure to show off his assets to the locker room as obviously as he could. The gym pants he wore left nothing to the imagination; you could actually see the veins of his king cobra sneaking down his left leg and below his kneecap.

Every time he saw his reflection in the mirrors around the weight lifting area, his hard-on came dangerously close to the limits of what his workout clothes could hold. Not that he would have minded. Everyone was invited to witness his manliness in full glory. But mostly his mind was on his lifting buddy Jonas.

While he waited for him to show up, Max got pumped up with an intense workout focusing only on his chest. Of course he didn’t feel like his swollen mega-pecs were big enough yet, even though his gym shirt was close to ripping down the center where his titanic jugs were forcing the seams apart.

“Hey, Max, how are…oh, my God. Are you for real?”

Jonas had arrived. He put his protein shake down on the bench press next to Max and pointed at his insane bulge.

“Dude, that...is not necessary. You don’t have to be ashamed of your cock! I’ve seen it, remember. It’s beautiful.”

“It’s even more beautiful now,” Max said, pulling down the waistband of his thighs a little. It became obvious that Max hadn’t stuffed his gymwear with a bunch of socks. The cock fighting for space between his built quads was real, and thick, and possibly now the longest cock on earth...by a lot.

“That’s not possible. I’ve seen you naked multiple times!”

Max closed the gap between them until he could smell the sweat on Jonas’s skin, until they were almost close enough to kiss.

“You better believe it is possible. I’ve grown a lot the last few days.”

To prove his point, he inhaled deeply and flexed his chest. His pecs swelled, audibly ripping his shirt and revealing a strip of bare skin. Max leaned forward, pressing his enlarged chest onto Jonas’s.

“I have to fuck. Now.” Max whispered.

Jonas couldn’t even look him into the eyes. He was mesmerized by Max’s magnificent chest, and his hand was already reaching for his swelling bulge.

Two minutes later they arrived at Jonas’s Dodge and piled into the back of the car.

“Fuck, Max, you’re more hung than a horse! How?”

“No fucking clue, but I know I want to get even bigger!”

“You want what?!”

Max had his cock out of his gym pants and was on top of his friend before they’d even closed the doors behind them. He tore the shorts off Jonas’s body and started pressing his monstrous hard-on against his tight hole.

“All day, all I’ve been able to think about is fucking someone with this big cock. Fuck, you’re so wet.”

Jonas’ cheeks were already slick with precum.

“Dude, you’re too big! It’ll never fit. You could split me in half!”

But with a little help from the gnomes’ magic, it suddenly did start to fit. Max’s cock slipped into Jonas like butter as Jonas clung for dear life to his friend’s shoulders. Soon, his belly was bulging outward from the cock rearranging his insides.

“Fuck, you’re tight.”

“I’m not tight, you are a fucking giant, oh, my God!”

One hand on the window, one on the ceiling, Jonas was sliding even further down onto Max’s cock.

“I’m gonna explode,” they moaned in unison.

Before he shot (for the sixth time that day), Max pulled his 18 inches all the way out and pointed his cannon at Jonas’s face. 12 shots later, Jonas’s face was white and dripping, and the car’s entire interior was sticky.

The gnomes, sitting on the windshield, high-fived.

To Jonas, when Max had withdrawn his cock, it felt like his soul had left his body and was now taking several minutes to sink back into place.

“You rode that thing like a champion,” Max said. “Can I call you? Lately, I’ve been needing release a little more often.”

Unable to speak, Jonas just nodded.

 

December 11th

Max’s holiday vacation was starting early this year. December was always exhausting, so he’d taken all of his time off before Christmas so he’d be ready to work the week between Christmas and New Year’s Eve. This Friday would be his last working day for a little while.

Max was busy kneading dough in the back room, keeping an eye on the pastries in the oven. But there was something else on his mind. Every time he passed the big polished fridge, he was scanning for further changes to his physique. He had woken up this morning with the same 18-inch hard-on and the same remarkable body to match. But he was hungry for what would come next.

The night before, he’d dreamed that his already-substantial balls had begun to swell. Already as big as chicken eggs to start, they fattened and grew until they were as big as coconuts. In his dream, he cupped them and shook them a little, and he could hear the hot cum audibly sloshing around inside as it accumulated.

He was smiling as he woke up, his face covered in cum and his monster dick jumping up and down on his chest.

What a way to start the day.

His smile shrank as he realized his balls were, in fact, still only slightly larger than average.

“Come on, guys,” he said, giving them a little squeeze. “I need you guys bigger too. Way bigger. Maybe coconut-sized. Or even cantaloupe-sized! Fuck, that would be hot.”

His mind couldn’t let go of the image of his package augmented by a giant set of balls. He rubbed another one out in the shower, thinking about it.

Now, at work, his apron concealed most of his ludicrous bulge. The only problem was that he couldn’t stop touching his cock, so the fabric between his crotch and his knees was covered in telltale flour prints.

It was only when he stopped thinking about it that the changes started.

It was evening, and Max was getting his workout in at the gym before they closed. His gym buddy Jonas was only a few machines away.

Max was in a black tank top and a ridiculously tiny pair of shorts. His anaconda was still over a foot long soft, and it had been a little tricky squeezing everything into it. The gym wasn’t crowded, but he knew that everyone in it was aware of him, eyeing bulge between his legs.

When he squatted, his package actually touched the ground now. Jonas dropped by every now and then between sets to grab a handful of it.

“Hey. I want you to fuck me under the shower again later. I’ve been thinking about your massive schlong all day.”

“Can’t get enough, huh?” asked Max. “Sure, I’ll meet you in there. Go ahead, I’ve got one more set.”

Jonas walked away and Max took a seat to do some leg extensions. He reorganized his bulge in his lap and started the set.

Weirdly, his legs felt tired earlier than usual. But it wasn’t because of the weight—it had more to do with the mass on top of his legs. Was there suddenly more of it than seconds ago?

“Oh, damn. Here we go,” said one of the gnomes, watching from the ceiling.

“Let’s see how big those spunk machines can get,” his companion added.

“Oh, shit, it’s happening!” Max shouted.

Luckily he was the only one left on the gym floor. He slammed the weights back into place and stood up. His package already seemed to be bulging out further, by a couple of inches!

“Will you look at this? Now this is a real set of cock and balls!”

The Aussiebum shorts he was wearing were starting to tear as the two spheres within continued to expand. As they surpassed coconut size, they suddenly started to swell even faster.

“Fuck, yeah! Give me some big-ass balls, Santa!”

The gnomes arched their eyebrows at each other.

Max arched his back and his soft 16-inch cock popped out of his shorts—there was room for it in there anymore. His shorts almost looked like a bra now, overinflated by his ridiculously large sack.

Max walked toward the locker room, but he had some trouble getting used to the new weight. His balls seemed to be getting in the way of his legs. They began to swing back and forth as he moved. They seemed even more noticeable than just seconds ago.

“Fuck, they’re still getting bigger, aren’t they?”

Yes, they are!” sang the gnomes from behind him.

“Jonas?” Max shouted as he arrived at the showers.

Another man, walking the other way, left the locker room at a run when he saw Max’s gym shorts, stretched to the limit by his prodigious nut sack.

“I’m here! I—”

When Jonas saw Max standing in the doorway, his voice died in his throat.

Max stopped, and his shorts chose that moment to explode with a loud bang. His balls tumbled down against his shins as scraps of torn fabric floated to the floor.

“I think I’ve grown again,” Max said, unnecessarily.

Jonas, already naked and wet, drew closer. He reached out to touch one of Max’s balls. Then he put his whole hand around one, then the other, gathering them up, until he was holding the whole sack in his arms like two large puppies.

“Are you kidding me?! These are fucking basketballs! Maybe even bigger! Holy fuck, how?”

Max grinned. “Just lucky, I guess! Every other day or so I have a growth spurt and I’ve just been growing so fucking much!”

“Are you still—”

“Getting bigger? Hell, I hope so! I wanna be fucking massive! I think Santa wants me to be the biggest, baddest bitch out there.”

Max’s cock had been slowly swelling, and now it reached its full 18-inch length, pressing against Jonas’s Adam’s apple.

He leaned in. “You ready to be inflated with cum, little man?”

 

December 13th

Two days later, Max was in his car on his way to the gym.

He tried to get comfortable in his seat, but a lot had changed in the last few weeks. The size his balls had reached was truly majestic, and he was thrilled that they finally matched his titanic cock—but in the process they had also outsized his whole wardrobe.

They were wedged up under the steering wheel now, and every time he turned, he squeezed them a little with his hands.

It made it challenging to focus on traffic.

Still, Max wanted more. Every morning he woke up lusting for his body to be still grander. It didn’t matter to him that he could hear people on the streets talking about him, calling him a freak. He loved that. For Max, it was proof that he had finally made it, that he had outclassed 99.9% of people. But even this wasn’t enough. He was so hungry for more size, more muscles, more everything. If Santa’s elves had come on Christmas Eve to strap him to a machine and pump him full of growth juice, he would have obliged happily. He would have cried tears of joy, probably.

Thinking about this fantasy, he had felt an irresistible hunger all day. He drove by several fast-food restaurants, almost stopping every time before reminding himself that he was on his way to the gym. When he finally pulled into the gym lot ten minutes later, his belly was growling loud enough to drown out the motor.

He was still waiting for a gift today. There hadn’t been any changes in forty-eight hours. His body was overdue for a growth spurt! Could the hunger be part of it?

Max had started waddling when he walked in order to accommodate his balls. The two basketball-sized orbs in his stretched-out shorts were hard to control. He could feel his cock starting to chub up with every step he took.

Changing in the locker room, it felt good to let his manhood breathe for a few seconds. He basked in the stares his balls earned when they fell free, almost touching his ankles.

The gnomes were on hand, as always. One of their voices emerged from a nearby locker.

“If his balls get any bigger between now and Christmas, he could end up stuck in the house. Which I think could be kinda nice, personally.”

“I think he’d still leave the house, just to parade them in front of everyone. He doesn’t care. He wants everyone to see.”

“No, I mean he might literally get stuck inside his house.”

They stared as Max posed naked in front of the mirrors. Flexing with his balls on display was enough to get him almost fully hard.

“Man, I’m fucking starving! And I ate a shit ton at breakfast today,” Max said. His hands rubbed his flat six-pack.

The gnomes exchanged a look.

“We should help him.”

“We definitely should help him.”

After Max had put on shorts—a futile gesture, since they didn’t really succeed in hiding anything—he turned around to find a gigantic bottle sitting on the bench. In messy handwriting, someone had scribbled “Free for Members” on the outside. He opened the lid and smelled the protein shake.

“Mmm. I fucking love strawberry.”

“Hit and sunk!” the gnomes whispered.

Max started chugging. His hunger was so strong, he didn’t even realize that the bottle didn’t seem to be emptying as he drank. He chugged for two solid minutes, then four, and there was still plenty left. The taste was perfection—smooth, rich, full of flavor but not too sweet. He couldn’t remember ever having anything so satisfying. He moaned in between gulps as he kept drinking.

It wasn’t long before his once-flat belly had begun to bulge outward. But his six-pack didn’t fade—quite the reverse. After ten minutes of gorging himself, his torso was looking more like a cobblestone road, abs popping out more and more. But the belly behind it was getting bigger and bigger.

As Max put the bottle down to catch his breath, and caught a glimpse of himself in the mirror. He was shocked to see the impact of his gluttony.

“Holy cow. Is that...me?”

He turned sideways and patted his muscle gut.

“Damn, I’m getting big! My arms and legs, too!”

He looked down at the bottle in his hand. A devilish smile appeared on his face.

“Need more.”

He threw his head back and drank deeply.

His muscle gut swelled again, growing fatter and fatter with muscle mass. He sat down to lean against the lockers as he drank, his balls coming to rest in his lap, his cock quivering with excitement, his gut expanding all the time.

He stopped drinking, entirely out of breath.

“Fuck, I’m almost full. Damn, this hurts!”

Max gave his belly a little shake. Gallons of liquid were sloshing around inside.

“If we don’t stop him, he’s gonna drink until he pops!” one gnome said to the other.

“You’re right. Wait.”

With a snap of his fingers, the bottle was no longer bottomless. Without noticing the difference, Max drank off the rest of it and stood up again. Now he was toting a big-ass cock, a super-sized ballsack, and an impossibly heavy muscle gut.

“Fuck, yes,” he groaned. “Look at the size of me! Shit!”

He found the locker room scale and stepped on.

“368 pounds—I’m a fucking giant! Burrrrp!”

His old gym shirt was three sizes too small now. The majority of his gut now peeked out of the bottom of it. Feeling full to the brim, he left the locker room. It was time to show off his gains.

Before the gnomes could follow, one nudged the other. Max’s lifting buddy Jonas was on the other side of the locker room. As they watched, he pulled off his shirt, revealing a pretty substantial muscle gut of his own.

The gnomes were impressed.

“Look at the size of that! Is that from Max?”

“He inflated his friend like a balloon!”

“It looks like all the pieces are falling into place. Fantastic!”

“Just a few more days. He’s almost ready for us.”

 

December 15th

Before Max woke up on the fifteenth, the gnomes got to work enhancing his wardrobe, working their way through his closet with big hand gestures. His shirts, pants, jackets—even his socks got bigger. All the boots on the hallway shelf grew by a few sizes. Even the single pair of gloves by the door stretched audibly, the fingers lengthening and thickening as they grew another layer of cotton.

When Max woke up, he was alone.

At first, he didn’t even realize what had changed. He rubbed the sleep out of his eyes and stumbled toward the bathroom, his heavy ball sack and gigantic soft cock swinging from left to right. They actually seemed a little smaller than yesterday, even though he knew that wasn’t possible.

It wasn’t until he couldn’t see his face in the mirror that he realized what had happened. Overnight, he had grown again, this time in height!

Max wasn’t just a few inches taller. He had become a staggering giant of a man. He had been tall already, but now he had gained another full twelve inches—seven feet and two inches! He was now bigger than any man he’d ever met.

His cock was immediately hard, pressing insistently against the sink.

“Holy fuck…this is just getting better and better every day. Wait till the guys in the gym get a load of this!”

Showering was an ordeal—he had to bend sideways in order to fit inside, and the showerhead was now at chest level—but he was surprised not to have the same trouble when he got to his wardrobe. Everything was bigger, and his clothes fit him perfectly again! He turned his head and for a moment he could have sworn that someone was watching him from the window. He shook the feeling off and pulled on his clothes. His newly augmented pants were generously cut around the crotch, but his manhood was still wedged super snugly in between his legs. The tight feeling alone was almost enough to give him a hard-on.

“Being big feels so fucking good…better every day!”

His stomach growled, but he had nothing in the fridge—he was eating for three these days. It was time to get groceries.

He spent a few minutes trying to fit into his car, but it was pointless. He couldn’t cram his body into the tiny space between the steering wheel and the seat. Even when he managed to squeeze his upper body inside, his monstrous pecs crushed against the sharp angles of his face, there was no room for his package at all.

Time to walk.

He couldn’t believe how much smaller everything seemed than it had just the day before. Everyone’s heads were suddenly way below him. He was at least a head taller than everyone he met, and twice as wide too. Every doorway he encountered now was too small—he had to bend down every single time.

Everyone in the market stopped and stared at him, but Max ignored them now. He was now able to see right over the aisles of groceries. The sensation of power was inescapable.

He picked up enough food for ten and got ready for breakfast.

 

December 17th

Max’s life was a little different now.

Wherever he went, he immediately became the star attraction. On the street, he heard people whispering when they saw him coming, pointing at him when they noticed him in restaurants, assembling in groups to take photos of him and talk about him after he’d left. The guys in the gym would follow him from room to room now, dogging every one of his booming footsteps. Max never stopped getting a kick out of it.

The effect was so pronounced that he eventually realized that there had to be some kind of pheromone his massive body was releasing. Everyone was so single-mindedly focused on his mass, inexorably drawn to his enormous presence—and they all had only one thing on their mind: sex.

One night, eating at a restaurant near his house, he found the waiter pressing a raging hard-on against his forearm.

“Everything to your satisfaction?” he whispered into Max’s ear. You’ll have to let me know if there’s any other service I can provide.”

“I will,” Max answered.

After he ate enough for three, driving his big muscle gut even harder into the table, he waddled back to the restaurant’s kitchen where he found the waiter.

“Do you have room for dessert?”

“I was actually going to ask you the same question,” said Max. He reached down to undo his belt. “Just be careful. I haven’t cum in four hours and I’m ready to explode.”

“Holy fuck, what kind of fucking horse cock is that? How did you get so huge?!”

By now Max was perfectly used to this reaction when people saw his 18-incher for the very first time. He knew it was an impressive sight. Together with his watermelon-sized pecs and his even larger balls, he was slowly becoming the eighth wonder of the world.

What he wasn’t used to yet was the amount of cum he’d been producing since he woke up today. This seemed to be his newest gift: his balls had gone into overdrive overnight. He had woken up in a pool of cum that morning, and yet somehow his schlong was still rock-hard and begging for release. He pulled his cock down between his melon pecs and into his mouth, just in time to almost drown in another load. It was too much for him to swallow. Even sixty seconds later, he was still blasting cum into his own face.

“Holy cow, he’s a machine,” one of the gnomes said after Max finally made it to the shower, leaving a sticky trail on the floor behind him. He’d had to pull the ruined sheets off the bed after cumming like a whale.

“He’s taking it better than that guy two years ago. Remember him? He couldn’t handle the cum.”

“Yeah. But his balls were even bigger than Max’s are.”

“That’s true. He gave us a lot to work with, didn’t he?”

“Max will be even better. Trust me!”

Max’s newly-hyperactive balls seemed to get fuller every hour that he didn’t jerk off. More and more veins would appear on his wide, heavy sack, drawing more and more blood down to his fat cock.

He had already been a heavy cummer before, he knew. Men he’d been with had always commented on how much he shot . But he was in another league now. Max couldn’t wait to find out how guys would react to this incredible quantity of raw, hot cum.

Even now, at the restaurant, his cock was already connected to the floor by a long, thick strand of pre-cum. More was accumulating on the floor between his boots.

“Are you…are you already wet? Fuck!” The waiter stammered.

“No, that’s just normal,” Max said with his deep voice, following the waiter’s gaze to the dark spot on his jeans. He jerked his soft cock once, immediately releasing a huge jet of precum. The waiter was immediately soaked.

Now I’m wet,” Max said, a cocky grin on his face. Then he pushed the waiter down to his knees and dangled his cock in front of him. The waiter leaned forward and took it into his mouth. The gnomes had to help a little.

“Fuck, little guy. You’re taking it like a pro!”

Max’s breath was hot enough to raise the temperature of the kitchen. The waiter could only suck and moan. Max was in ecstasy. He raised his biceps and squeezed them hard, flexing for himself. God, was there anything hotter on the whole planet? He pulled on his own huge nipples as more and more of his cock disappeared down the waiter’s throat.

“Yes, take that cock! I’m gonna fatten you up with so much cum! Ngghh, fuck, here it comes!”

His balls had risen up in their massive sack, and with a cry from Max, they began to unload. Stream after stream blasted out the long shaft and into the body of the little man kneeling in front of him. The waiter groaned loudly, unable to pull away from Max’s tight grip—he was forced to take every drop. The little vest he was wearing grew tighter and tighter. A button in the middle popped, giving up the fight. Then another. Soon, a churning mass of belly had forced its way to freedom and was spreading across his thickening thighs.

Max was breathless.

“I’m filling you up so good, man. Look at you fucking grow!”

When the giant was finished, pulling his cock from the waiter’s mouth with a wet slurp, the little guy wasn’t so little anymore. He now sported a big, tight potbelly and was at least 75 pounds heavier than before.

“You blew me up! I’m so full of cum!” the waiter cried. He rubbed his new, pregnant-looking belly in wonder. Then turned his attention eagerly back to Max’s cock.

“Want to go again?” Max said, but almost before he’d finished the sentence, the waiter was back on the ground, sucking his cock back into his mouth.

Two hours later, he was back under the gym showers, this time with his cock buried deep inside his friend Jonas. He’d needed so badly to cum again. Luckily, his friend was more than ready to help him out.

While fucking, Max thought about the waiter at the restaurant that he’d left 145 pounds heavier than before. The little man had gotten so fat, so fast, he’d barely been able to hoist himself off the kitchen floor afterward. The mental image got Max ready to cum again almost immediately.

As his balls pulled in again, he wondered idly if he should have warned Jonas about his new ability.

 

December 19th

Already, it was a miracle that Max was still allowed in public now that his cock had started oozing a steady stream of attention-seeking precum. But things got even weirder on the morning of the nineteenth.

He was walking by the restaurant he’d enjoyed so much two days before when he noticed the flirtatious waiter. Max couldn’t believe his eyes. The dude was jacked as fuck!

The 7’2” giant stormed into the empty restaurant and walked up to the bar.

“What the fuck happened? The last time I saw you, you were a 300-pound cum-blob!”

“Hey, man. Nice to see you again so soon! I don’t know what to tell you; this is how I woke up today. The fat was gone and I looked like this instead.”

The waiter was radiant with joy. He wasn’t the pear-shaped behemoth Max had left behind; now he was 280 pounds of pure, lean muscle. The uniform he was wearing looked ridiculous on him—it was at least three sizes too small and the seams on his biceps had already burst open, the buttons audibly begging for mercy every time he inhaled.

“Looks like your cum can give you a lot more than just a huge gut, sweetie. Thanks, babe, I love the new me. I’m free tonight, if you wanna see what another round can do.”

Max barely heard him. The wheels in his head were turning—he had to get to the gym!

He still got the waiter’s number first.

In the last 48 hours, no one had gotten as much of his cum as his friend Jonas. More than anyone else, his gym buddy couldn’t get enough of his dick.

When Jonas had come by his house last night, he had already been 420 pounds, with a belly that reached legendary proportions, but he wanted even more. He would have endured anything, as long as Max kept filling him with his sweet juice. When he left, he’d been 490 pounds, with the promise of more to come. Seeing him waddle away, a walking cum barrel, was enough to fill Max’s balls right up again.

Max practically ran all the way to the gym.

When he reached the doors, a little crowd had formed to wait for him. A wild din of voices flooded the gym lobby.

“Make me bigger too!”

“Grow me, grow me!”

“You can fill me as many times as you want!”

But leaning against the counter, looming behind them all, was Jonas, and Max didn’t have eyes for anyone else.

He looked magnificent. He wasn’t the 500-pound blob Max had created the night before. Instead, he had transformed into a massive, 410-pound off-season muscle mountain. His grin reached from ear to ear when he saw the hard bulge growing down Max’s thigh.

All Jonas was wearing was a snug pair of underwear. Nothing else fit him anymore. Still 5 foot 8 inches in height, he was now as wide as he was tall, unbelievably dense with muscle mass.

It turned out that Max’s upgraded libido was more than a match for Jonas, and plenty of others. Within 24 hours, everyone in the gym was jacked beyond description.

Max’s balls hadn’t been this empty in days! By the time he came for the fiftieth time, they were down to the size of coconuts, minuscule by his standards. But after he helped himself to a gallon of water, he noticed they were starting to swell again.

“Nothing makes me cum harder than making you guys bigger,” he said to the crowd gathered around him. They cheered. Even after a full day, Max still outsized everyone in the gym by several inches. He was the Santa Claus of muscle mass, and the supply of gifts was endless.

Jonas, having surpassed 500 pounds of muscle, had finally stopped getting bigger. He was a wall, unable to move like a regular human being anymore. When someone offered him an oversized shirt, he learned that he wasn’t able to reach his own head anymore. His pecs got in the way of his arms. His back had become too wide for him to reach up. His traps and neck were also a big problem.

“Come on. Make me bigger. One last time.”

“You didn’t grow the last three times I fucked you, Jonas,” Max said happily. Seeing Jonas this big made him only want one thing: to grow his muscles even bigger. But it seemed that Jonas’s body had no more room to grow, which was probably lucky for him. “But if you insist, I’m happy to blow another load. Hell, my balls are full again already.”

And even though Max’s aching cock felt like a truck had run over it—twice—he was immediately hard again, ready to slip into Jonas’ huge donut hole.

“Fuck, the bigger you get, the better it feels, Jonas!”

“Mhhh, yessss…I was just thinking the same. Holy fuck! You have the most incredible cock!”

When Max came this time, Jonas hyper muscle gut was the only thing that swelled. Dark red stretch marks covered the sides of his strained abdomen. His head was slowly disappearing between the valleys of his shoulders, pecs, and traps as the incredible orgasm rolled through his system. He rubbed his huge, overfilled roid gut.

“So full, fuck! That was so intense, man! If you don’t stop inflating me, I’m gonna pop one day. Jeez!”

Max looked around at the assembled mass of jacked, built guys who had gathered to watch. He realized he was now entirely surrounded by fellow muscleheads. His own army of professional bodybuilders.

“You know what, guys? I think this is gonna be the most amazing Christmas ever.”

 

December 21st

Home alone, in the middle of the night, Max was in a weird state between wakefulness and sleep. His mind was running at lightning speed, unable to stop thinking about the last three weeks. His brain was constantly reminding him how much more of him there was now, and playing scenes from the last few days at the gym.

Earlier that night, after almost 48 hours of nonstop sex, Max had finally taken a shower and gone out to eat. Even though he was off work now until January, he decided to head back to the little bakery. Max knew that his colleagues probably had some baked goods that hadn’t been sold over the course of the day. With grocery stores already closed and his fridge at home empty, it was his best chance to fill his stomach.

When he came in through the back entrance, he found the bakery empty, the lights dim.

“Anybody here?” His deep voice echoed in the empty kitchen.

He was over a foot taller now than when he’d last been in here, and the place felt so much smaller now. He found the box with the day’s leftovers next to the fridge and dove in head first.

“Mm, the amount of food that goes to waste here every day…it isn’t right. But...more for me!”

Over the next hour, his mouth and hands never stopped moving. He stuffed his face with pound after pound of food, until his huge muscle belly was bulging.

“Damn, I’ve never been this hungry before. This body needs so much energy!”

When he was finished, he opened his pants to give his gut some room. His eager cock slipped out along with it.

“Woah, big guy. Haven’t you had enough already? We just fucked the whole gym for two days straight.”

His large dick didn’t answer, but its apple-sized head was covered in pre-cum, and Max could see it pulsating in the weak light.

“Yeah,” Max said. “We did inflate those roid heads pretty good, didn’t we?”

Max caught the eyes of his reflection in the big industrial fridge. He was sitting next to the empty box of food on the ground and his cock was pulsing against his enormous muscle belly. It gave him an idea.

“Fuck, if this works…” he whispered into the darkness of the little kitchen.

“He’s going to do it,” one of the gnomes whispered to the other from the top of the fridge.

Max was lowering his mouth down onto his 18-incher, and almost immediately cum began to flood his mouth in powerful waves.

“Damn, he’s such a great cummer!”

“He’s got great control,” the other gnome commented.

“Look at how big his hands are when he massages that huge ballsack.”

“He can’t inflate himself, can he?”

“Honestly? No fucking idea. No one’s ever tried before. But look—the ring is glowing on his finger again!”

Their voices were too small, and Max’s own brutish grunts were too loud, for him to hear. As he gulped down rope after rope of semen from his swollen sack, he could only think about one thing. Grow, grow, grow!

Still thirsty, he pressed his balls together, praying for another gallon of muscle growth juice. He had never felt more full in his life.

He moaned as the massive cock slipped from his mouth with a wet slurp, covering him in three final spurts of thick white spunk. He shook his deflated balls.

“Come on! Inflate me! Make me bigger! Make me crazy huge!”

Max looked down at his even more distended abdomen—he knew it was there, even though could hardly see its sphere over his two juicy pecs—and waited impatiently.

“Damn, it looks like he can only inflate other people.”

“Maybe it just takes him a while longer? He really gorged himself on that food. Maybe it’s blocking his system.”

Max felt tired and disappointed. He had been dreaming of the spectacle he would make when he returned to the gym as an ever greater mountain of a man, ready to inflate his friends even further.

He left the bakery through the back door, not even bothering to zip his pants back up. As he made his way through the snow, his soft anaconda hung loose, swinging mesmerizingly back and forth.

Finally, Max made it back home. After stripping his clothes off, he took another look into the mirror and noticed that his cum gut still hadn’t gone down.

“I love this off-season look,” he said, stroking the nine inches of monster cock hanging down from his groin, “but why can’t I pump myself bigger like I can everyone else? Damn, I hope tomorrow brings me something new. It’s almost Christmas, and I still have time to get way bigger. I wanna leave everyone else at the gym in the dust.”

He turned off the lights and headed to bed.

Hours later, his chest felt tight, as if someone were standing on it. His legs twitched uncontrollably, and his cock was out of control, growing hard and then soft again every few minutes.

At four in the morning, he flipped on the lights and threw off the blanket.

His feet were dangling off the edge of the mattress. He had grown again.

“Yes!! Look at this!”

He tumbled out of bed, scrambling to get a look at himself in the mirror. Standing, Max very nearly hit his head against the ceiling. He didn’t realize just how big he had gotten.

“He looks like he’s over eight feet tall now,” one of the gnomes marvelled from the shadows of the bathroom.

“…and fucking hot too.”

Just looking at his new reflection was enough to get Max hard. He was now 8’2’’ tall, and had put at least another an inch or two on his cock. His chest and belly, his arms and legs, everything was now covered in a thick layer of dark hair. He was even more manly than before—as if the almost two feet of cock hadn’t made that clear already.

With trembling hands, he squeezed his pecs. They had been big already, but now they were enormous; almost twice as big as before: a twin set of ripe watermelons, jiggling right under his nose, pressing up against his chin. He grabbed them hard and moaned ecstatically.

“Fuck, I’m becoming a bodybuilding tit monster. Holy shit, they feel so tight!”

Max found his bottle-cap-shaped nipples with his fingers and noticed that they were as wet as his cockhead.

His mind wasn’t even able to process all the new stimuli flowing in. He lifted his arms and almost crushed his skull between his own monstrous biceps. The forests of hair under his arms were so dense and dark smelled so good that he almost shot right there and then. He wanted to press his head into his own pits so badly, and couldn’t until he had Jonas there to do it for him.

“Fuck! I can’t wait for Christmas to come.”

 

December 23rd

It was the 23rd of December and Max was about to visit the gym for the last time ever. But he didn’t know that yet.

The gnomes had been feeling mischievous and hadn’t grown his wardrobe along with him this time, forcing him to walk to the gym in his old, way-too-short clothes. He had thought about going shopping, but who sold anything big enough to fit an 8-foot giant?

In the end, it didn’t really matter. Max found he wanted everyone to see him in all his glory. He didn’t care that his midriff with its treasure trail was peeking out, that his sleeves were fully torn open, and that the anaconda bulging in his shorts cast a shadow the size of Nevada. His pecs were finally too big to fit in any kind of clothing. They had burst right out of his v-neck and were free to flex in the open air now.

The gnomes, disguised as robins on a garden fence, watched as Max entered the gym.

“Do you think he’s ready for harvest?”

“Mm…maybe let’s wait till Christmas.”

“You don’t think he’s done growing yet?”

“Hell, no. Did you see him just now? I could see him still changing as he walked to the gym.”

“Really? How?”

“His face looks more square. He’s getting more attractive.”

“Everyone else has always been done changing by the 20th. They have to be done before Christmas.”

“Well, this one is different. Let’s give him two more days and see how much bigger he gets.”

“God, this is gonna be good.”

“He’s gonna give us enough for two years.”

“At least!”

One of the last changes happened after Max’s intense gym session that day, in one of the shower stalls. It was a little inconvenient, showering in there, since his back and his shoulders were in constant contact with the walls on both sides now. He was a monster of a man. His junk, hanging down, looked as heavy as a wrecking ball, and almost as big.

It felt good to wash off the layer of sweat. The black hair under his arms felt almost thicker than his head hair. He kneaded his cobblestone-shaped abs with his fingertips.

Everyone else was as in love with Max’s body as he was. He was aware that people were peeking into his shower stall from every direction, but he didn’t mind. By now there was no one left in the building who hadn’t had his cock shoved up their ass.

The change began as he was soaping up his huge quads. He had to do it by feel since his chest got in the way of actually seeing them.

Even in the distorted reflection offered by the little shower knob, Max could see that his face was getting wider. The angle of his jaw looked sharp enough to smash stones. His cheekbones became more defined, making his smile brighter and his eyebrows thickened and darkened. His beard stubble was visibly growing at an alarming rate.

“Fuck. Now I’m giving off some serious muscle daddy vibes.”

And then, out of the blue, a wave of pleasure surged through Max’s entire body. He was having an orgasm! His legs, ass cheeks and abdomen contracted hard and he began to tremble. A hard stream of pure cum shot from his cock, hitting the wall with a splat that was audible even over the roaring water.

“Damn! Where did that come from?! Mm, fuck! I’m still cumming!”

A minute later, when it was over, the drain was completely clogged with thick white seed. Max still hadn’t even touched himself.

He went to his locker, still dripping, having to hold the too-small towel in place around his waist. He was aware that around him people were taking photos and videos, but he kept moving, giving them nothing but a little bicep flex.

Then, before he could even get his sweats back on, he came again. It had been less than ten minutes since the last time.

“Holy fuck, Am I cumming again? What is wrong with my balls?”

But the wet warm liquid covering his feet was answer enough. Seconds later, Max was standing in another puddle of his own creation.

“So…much…cum.”

One of the muscleheads who’d been changing at a locker nearby drew closer. “Dude. You need a hand with that?”

“Darren, look at you. You’re already 440 pounds of muscle. You don’t need any more.”

I don’t, but it looks but your cock sure needs to be emptied somehow.”

“I think this might just be just the way I am now. I’m producing so much testosterone and cum that it’s just starting to flow on its own.”

“Fuck! What does it feel like?”

“Like I’m getting a crazy good fuck every few minutes. Speaking of which...do you have a condom?”

Max got home 30 minutes later. He had come three more times en route. The condom he’d borrowed from Darren was filled to the brim. By the end he’d had to hold it in place with his hands so it wouldn’t detach as his cock kept cumming.

Max tied a knot in it and the beanbag-sized balloon flopped toward the ground. The churning mass inside was warm and dense, stretching the thin latex to its absolute limit, as though aspiring to get as big as Max’s glistening cock itself.

Max wondered how much capacity the local sperm bank had.

 

December 25th

Despite the cold outside, the air in Max’s room was humid, the heat making a glowing aura around the lights on the Christmas tree. It was here: Christmas morning.

Max was smiling even before he opened his eyes. He knew right away that he had grown again in his sleep.

“Merry Christmas, man,” he told himself. His basso profundo voice gave him chills. “Let’s see what Santa got you this year.”

Lifting his upper body out of bed was a lot of work. He had gotten taller and heavier again; he suspected he might still be getting bigger even as he moved.

Before going to sleep, Max had put another condom over his colossal 2-foot cock. The night before he had continued to cum, like clockwork, every ten minutes, and the volleys of cum spraying all over his bedroom and dripping down on him had kept him awake. The condom, his improvised solution, seemed to have worked, but now he found himself face-to-face with a hyperinflated latex cum tank.

“Holy shit, is this all from last night?”

The gnomes had amused themselves by preventing the condom from popping, and so white sphere had continued to grow impossibly large. Now it was level with the top of the door frame. It looked like someone had parked a white van in the middle of Max’s bedroom.

Max’s cock had been completely engulfed by the massive balloon. And it wasn’t just the condom: his whole body had continued swelling bigger overnight. His pecs were pressing permanently against his face and arms now. They were covered in fur, making his fist-sized nipples point directly downward, out of his view. Max would discover his new nipples later; for now he was busy exploring the new mass of his legs with his fingers.

“Fuck, how big am I now?” he cried, jubilant. “Santa, you’ve been so generous this year!”

It was time to free his cock. He peeled the condom off the base of his penis until the seal broke. As though a dam had broken, the cum began to gush out of the condom and onto the floor.

“Now that is a cock!” roared Max over the roar of his own semen. “Look at that! I’m a fucking whale-cocked god!”

Perpetually hard and covered in arm-thick veins, his ten-foot monster of a dick was now pressing against the door of Max’s bedroom. His cock continued to blast cum against the door as the balloon on the floor continued to deflate.

“I have to call Jonas. He’s got to help me out with this.” Visions of fucking his friend with his newly enhanced monster danced in his head.

Max grabbed his phone...and learned that his hand had become too big to use it. The camera didn’t recognize his testosterone-enhanced face anymore; even his pinky finger couldn’t help pressing four buttons at once when he tried to type.

The doorbell distracted him from this dilemma. Max heaved himself up to answer it, following the ankle-deep river of cum that was flowing out the door. He somehow squeezed himself through the door frame, shattering it in the process, and very nearly got stuck coming down the stairs because his hard cock was too gigantic to make it around the corner of the landing.

“I’m coming!” Max yelled, as his cock continued to spray gallon after gallon of cum. “I’m definitely coming!”

Max needed all of his remaining flexibility to open the front door. Had his muscles grown even bigger since he’d gotten up?

“Look at you!”

Jonas was not waiting outside. Instead, there were two other men there, and only one of them was familiar. It was the big, hairy guy from the bakery—the bull in men’s clothing.

Max had not attempted to put on clothes. His naked glory was on full display.

“You were right. He wasn’t done growing,” the thicker of the two men said.

“Who the hell are you?”

“We are the reason you’re this big.”

“You’re what?”

“Can we come in?”

Max shuffled back to the couch and planted his double-wide ass on it, his hairy cheeks spreading to engulf two full cushions. Max’s cock was aimed at the ceiling of the living room, a steady stream of cum trickling down the shaft. He knew it was only a temporary respite, though—he could feel in his balls that he was about to start blasting again.

The gnomes took a seat opposite him, on the other side of the coffee table where Max’s balls rested.

The man Max recognized had a V-shaped torso and the body of a thick muscle god. The other one was fluffier. He was big, too—at least 7 feet tall—but he also had a round gut filling out his jolly Christmas sweater.

Max smiled at them as another geyser began to erupt from his whale cock. He wrapped an arm around it, jerking it to the best of his ability, and another blast erupted from its tip.

“Are you surprised to see a man this big? I’m huge!” Max moaned, his guttural voice descending even lower.

“You sure are a big boy.”

“And we’re here to help you with that,” the other added, eyes on the cock.

“Help me?”

The big gnome glanced at the fat one. Not the brightest, is he?, his look said.

The other raised his eyebrows in reply: But he’s the biggest.

Should we just tell him the truth?

The other nodded. It was time.

“Did you ever wonder who sent you the ring at the beginning of the month?”

Max was hardly listening. He was busy playing with his round, full pecs. His hands had finally found his gigantic, cock-like nipples, and were enjoying them to the fullest.

“Ring? What ring?”

“The ring you put on.”

Max raised his hand and saw his ring finger. He had forgotten about the glowing mark the ring had left behind 25 days earlier.

“Oh, my god. This”—he squeezed his pecs, pressing them against his face—”you two did this?”

The muscle gnome nodded, while the other just gave a cheeky smile, scratching his gut.

“We need someone to give us a little energy boost every now and again. And you seemed perfect.”

Max was back on his feet and caught the two gnomes in a hyper-muscled hug.

“Thank you! I love it, I love it, I just fucking love it!”

The faces of his guests disappeared into the soft tissue of his pecs. The two men shivered with anticipation.

“Can you make me even bigger?”

The two men exchanged glances.

He wants to grow even bigger?

That’s never happened before.

But look at his guns!

And his cock!

Let’s get what we came for first. Then we’ll see.

“Can you? I want to be bigger so bad!”

“You’re a pretty big guy already,” the fat gnome said cautiously.

“Not big enough!”

“Okay, sure…if you don’t mind helping us out first.”

“I’ll do anything you want!”

“Well, you should know what’s happened to you. The two of us,” the thick gnome began, “are not human. We are what you might call magic. We don’t have to eat, we don’t have to drink, but at least once a year we have to drink a certain ambrosia in order to stay strong.”

His friend continued: “We usually plant a magic seed into an oblivious candidate and let it grow. Humans, you see, can’t use magic, even when they are full of it. Which gives us the chance to use you as a garden…”

“…and build a fountain of ambrosia inside a human form. The magic multiplying inside your body follows your own desire. It makes you bigger and then it has more room to propagate itself. Symbiosis.”

“But no one has ever grown as big as you, Max. You can give us enough magic to keep us alive for many years! You’re radiant with it. Your very sweat is pure magic.”

Max hesitated. “What will happen to my size once I feed you?”

“What happens when you harvest the fruit from a garden? The garden doesn’t get smaller. It just gets back to growing the next season of fruit.”

“So I can keep my size?” Max exclaimed. His sudden movement made the legs of the coffee table break under the swelling weight of Max’s balls, depositing them on the floor with a bang.

“Better than that. With the magic you give us, we can actually make you even bigger.”

“Well, what are you waiting for! Come get your magic and grow me! Grow me as much as you can.”

The gnomes exchanged looks one last time. But it was time to get to work.

They started at his face and worked their way down. Within moments, Max was lying on his back on the floor, lost in bliss. The two men turned out to be the horniest bastards he had ever met. They kissed him like there was no tomorrow; Max had never experienced anything so gentle and yet so brutal. While one of the men’s tongues was still inside his mouth, the other’s began wandering down his body, planting kisses everywhere.

The muscle gnome found Max’s cock-like nipples and started jerking them. As he played with them, they started to inflate.

“Oh...this is new.”

“Uhh. Be careful, little guy, they feel sensitive this morning.”

“I can see why.”

He squeezed the six-inch nipple between his fingers and Max moaned loudly. A drop of white liquid appeared at the tip of Max’s nipple.

“Ohhh, I’ve waited all month for this,” the gnome breathed. Then he stuffed the thick nipple into his wide open mouth and began to suck.

“Uff, damn, that feels good!” Max groaned, breaking the kiss with the other gnome. “Get down there and suck the other side. Empty me out.”

And so the feast began. Attached to his chest, the gnomes enjoyed gallon after gallon of their magic juice. Max grabbed the backs of their heads and pressed them even harder against his chest as they drank greedily.

And then Max saw them swelling. While one of them was putting on more muscle mass with every swallow, the other was becoming fatter and fatter. Both of the 7-foot-tall gnomes looked to be over 400 pounds already.

“Fuck, look at you, guys! You’re getting as big as the guys at the gym. Maybe even bigger!”

The suckling continued without stopping for the rest of the morning. It was heaven for all three of them. The gnomes continued to gulp the white liquid from Max’s chest, reveling in the feeling of its magic flooding their bulging bodies.

Hours later, the two gnomes tired simultaneously and took a step back. They were both out of breath, rubbing two very different bellies. One of them had a wide, beach ball-sized muscle gut, still covered in bulging abs, while the other had a monstrous lard gut that hung down to his knees.

“Look at you guys. You look phenomenal.”

The gnomes stared. “There’s still more magic in your body…”

“…but we are already full.”

“I thought this wasn’t possible…”

“…but you’re proving us wrong.”

“Come on guys, we haven’t even started on my balls. I haven’t come at all in the last three hours! You’ve got to help me. I need to fill you up. Both of you, now.”

Before either of the gnomes could question the logistics of him fucking both of them at once, Max’s entire body began to glow in the warm air, like a Christmas light.

“Is this…”

“…magic? That’s impossible.”

“It can’t be!”

“He’s human! How can he…?”

Max clenched his teeth, widened his stance, and focused all his energy into his manhood. Slowly, his monstrous cock shifted toward the left side of his lower abdomen, and a second cock began to emerge.

“Max! How are you doing this?”

“I’m not doing anything! It’s the magic inside me. It wants to come out! It wants me to grow! Fuck, guys, I’m getting even bigger!”

Max’s body stretched taller still, swelling to over ten feet in height in mere seconds. His head collided hard with the ceiling, but his growth didn’t stop. The second cock grew rapidly, until it was fully the size of the first in just a few massive growth spurts.

“Are you guys doing this?! Now my muscles are getting bigger again! This is incredible! Thank you, thank you, thank you!”

“We’re not doing anything, Max!”

“It’s all you!”

“Holy shit!”

The gnomes knew what to do. With the aid of a little bit of magic, they were each able to take one of the gargantuan cocks. Max began to cum immediately, and he didn’t stop until every ounce of magic was gone from his body.

The neighborhood streets were covered in snow, shrouded in winter silence. There was no one outside, no cars on the streets. Nothing could be heard but a cat, treading lightly, prowling through the snow…and the creaking beams of house number 1988. Seconds later, the neighbors were startled by a loud bang. Number 1988, the house with Max Grant on the mailbox, had just exploded into a million pieces.

Three men were visible in the ruins of the building. Not one wall had been left standing—nothing was left but the three of them, groaning and panting in the moonlight.

The two gnomes were bigger than ever. Slowly, they rolled over, saw each other for the first time, and gasped in unison.

Holy fuck, look at you!

They each had expanded by more than half a ton of muscles and lard. It was the biggest either of them had ever been.

Next to them, completely spent, Max was still catching his breath. He was 20 feet tall now, with most of the ruins of his own house buried under his body. For the first time in what felt like days, his cocks were finally deflating.

“Thank you, guys. You did it! I’m actually empty for once!”

The gnomes didn’t respond. It would be a while before they could walk or talk.

“How about this: why don’t you two come back again next year and I can give you even more of your magic? Of course, you’d have to plant another seed in me...and I would have to grow for you for another month...”

The gnomes were too exhausted to get up, but they both had devilish grins on their faces. They already knew they were going to accept.
