Here's a com done for nska on FA at https://www.furaffinity.net/user/nska of his German Shepherd Zahn wanting to bulk up by changing energy to mass.

There is a lot of energy in the world, perhaps more than he thought. Doesn't mean he won't enjoy it.

Story contains male actions, mass vore, muscle growth, universal macro growth, nudity and big shep dicks. No one under 18 allowed.


Zahn was a large German Shepherd with a mix of white and blue fur. His eyes were heterochromatic, between green and grey, and he naturally stood at a very large eight feet, six inches tall. He had a well defined body, but there was always a desire for more. He liked what he saw when he looked in a mirror, sure, but the need was there. The want to get larger and bigger. Exercising and diets only went so far. Even vitamins didn't do anything. And though he was proud how all of this was all natural, he felt that it was time to go to more extreme measures.

After weeks and months of trying, though, Zahn had discovered a new way to get bigger. There was so much energy out there. Potential energy. And the thing about energy is that it could be used to make something new. Latent energy, magnetic, electric. All types of energy that just was there, waiting to become something. So why not make that energy his own?

He was going to try and absorb the energy around him.

Zahn picked his spot. A small municipal park in the suburbs outside of the city. The german shepard was simply seated on a park bench, watching several of the other furs go about their day. A few joggers were running past, there looked to be a couple having a picnic on a grassy hill, and a few others crossing through, looking down at their phones. Right now, Zahn was just another face in the crowd, but if all went according to plan, soon all eyes would be on him.

He closed his eyes for a moment. He needed to focus. To imagine all of that energy around him, all over. Just waiting to be made his. Zahn took a deep breath, and began to reach out, pulling on all of the energy around him. At first, there was nothing. But, a few moments passed, and Zahn could feel some tingling about him. It was slight, but he could feel that latent energy flow into him.

The german shepherd needed a quick test. He flexed his arm. The shirt he was wearing was slightly tight around the sleeves, but not tight enough to be restrictive. Under his shirt sleeve, his bicep bulged from the flex. The cloth stretched some, but it returned to normal when he relaxed. Zahn focused a bit more, feeling more energy coming into his body as he closed his eyes. He waited a single minute, then he flexed again.

Once more his bicep pressed upward, and this time, his ears perked at the sound he was hoping for. A ripping sound. A sound that showed that the tight sleeve on his shirt couldn't hold in the bulge that was his bicep. A grin crossed his face as he opened his eyes. It was slight, but he had indeed gotten his bicep large enough to rip his shirt. But that wasn't enough.

No, Zahn hoisted up his other arm and flexed as well. He only needed to do so once to hear that rip coming from his other arm. It had ripped right at the edges as well, a start but there was so much more to it. The german shepherd grinned, and turned his head slightly as a pair of joggers ran passed. One of them whistled impressed at the flexing canine, but continued with their run.

A start. But Zahn wasn't done yet. He needed more. He wanted more!

He focused more, concentrating stronger on the latent potential energy of the world around him. Zahn used his full focus and attention on this task, taking a few steady but deep breaths, and tried to feel it entering him. Steady breaths, in and out, and more energy from the world around him started to flow into his body and form. It felt easier now, more natural.

A soft stretching sound came from his body. He looked over at his arms, seeing if there was any increase to be had there. They didn't seem to have changed much, not from last time. Curious, he looked down. Then, he realized what was going on. The slight sound of his body growing was literal this time, as the energy he was absorbing was adding to his height. He had grown a few inches, enough to make his midriff raise on his shirt.

"No sense in stopping now." He thought to himself.

Zahn concentrated again, and this time he could feel the energy tingle as it worked its way into his body. The German Shepard was now feeling it move through him, coursing through his body like lightning. It flowed through his nose and mouth as he took a few deep breaths. It flowed through his fingers as he extended his palms, pulling it towards his core. Even through his toes, which had grown out with the rest of his body. He started to wiggle them, and soon, the dark blue furred appendages at his feet felt tight. A firm push, and then he felt his feet burst out of his shoes, leaving them a mess of canvas and rubber strewn at the ground.

Zahn was starting to get more attention now. Not just from other furs passing by and giving him a second look. Now he was getting gawks and looks of shocked surprise. And his body was still growing as he pulled more ambient energy out of the world around him into himself. He needed to try and make it steady, because it was still coming in periodic bursts. Suddenly nothing, and then suddenly expanding out nearly a foot in height and getting wider by several inches. But it felt great, and he could feel his control over it getting stronger. The stronger it got, the larger he was getting.

He soon had a small crowd of about a dozen furs looking up at him. He had passed fourteen feet in height, and his clothes kept ripping as he expanded. His pecs were showing off between the ripped shreds of his shirt and his pants were soon to fall. He grinned as he looked down at the crowd past his chest shelf. He gave a huge flex of his pecs and then twisted slightly to bulge his thighs out. As he did so, he pulled in the most amount of energy he had so far.

The pants that Zahn was wearing, which held out for so long against the inevitable, finally lost the battle. A massive red rocket of a cock burst free. Before he had been growing and absorbing energy, his dick while hard was already nearly three feet long. But now, as he was expanding from the energy and power of the world around him? It was fast approaching five feet and growing. His sheath bulged as the knot started to slip out, and a mix of gasps and whispers from the crowd were getting louder.

The sounds of his muscles stretching and growing under his fur continued to fill the air. Now, not only was he pulling energy around him from his breathing and extremities, now he was pulling it in through his dick. That tingling sensation that had been working through his body was now flowing down his shaft and into his sac. His balls started wobbling slightly, the energy flowing into them making them increase in radius, each getting larger and larger and hanging lower and lower.

There were more furs joining the free show of the crowd, a group of about thirty now ogling the muscular and growing shep. He flexed again, admiring his own body as he gazed upon a bicep, letting the beefy arm bulge expand upward. He licked at his muzzle, watching a throbbing vein pop along the surface that was thicker than one of his fingers. Another steady increase in his size soon had his feet bump into the closest onlooker.

Zahn now turned his attention to those who were watching him. A toothy grin emerged on his face, before he leaned forward, brought his arms together under his pecs, and then flexed out his back. A sudden surge of muscles expanded outward behind him, spreading his shoulders out and working all the way down to his tail. A further expansion of his spine even increased the length of his tail before he stood up straight again, now close to twenty five feet tall.

"Attention all!" Zahn said, "I am now the biggest, strongest, toughest man alive!"

His voice boomed out through the park, carrying on the wind, and flowing to all four corners of the grassy recreational facility. Everyone was watching him now, turning to see the ascending and growing canine as he began to reach the size of the trees.

"And as the biggest, strongest, and most powerful man alive, I demand your admiration and affection!" Zahn declared, "You will give me all of your worship. I crave it! Give yourselves to me!"

The crowd looked towards each other. A few seemed scared to approach the growing giant. One did decide to come forward and rubbed along the thick white fur along the lower half of Zahn's leg. After a few more seconds, several more of the crowd came forward. Soon, the shep had several hands rubbing along his firm lower body, feeling and squeezing at his muscles. But several more still weren't getting the hint.

"Don't make me repeat myself." Zahn said to the ones who had not yet given themselves to worshiping his body, "Get going, or else!"

To prove that he was serious, the beefy german shepard reached to one of the hesitant furs, a grey tabby, in the back and grabbed him in his massive hand. He squeezed slightly, enough to cause discomfort, but not to squish him in his hands. Then, he flicked him into the air like a popcorn kernel and snapped him out of the air as he fell, his jaws and teeth crashing around him before swallowing the male whole. His green eyes flashed towards the others.

"Do I make myself clear?" He said, gulping once to show the small bulge going down his throat and vanishing behind his muscular chest. The feline fur didn't even make an imprint behind his abs.

That got the message across, and soon the entire park was coming towards him. Zahn grinned and soon sat down, making a shockwave emerge from where he planted his keister. Several furs fell over, and several more fell towards him, grabbing onto his muscular body to stay on their feet.

Zahn hadn't stopped absorbing energy around him, and then noticed something. His growth was getting faster. The more furs that came to rub at his muscles, feel his balls, squeeze at his knot, the bigger they were all getting. It struck him that all of this worship and admiration, the effort they were putting in to please him, it was a type of energy too. The more he was getting, the bigger he was growing!

"Keep it up! You're all mine now! I own you all! Your lives are my fuel!" Zahn ordered to the micros at him.

The canine was soon outgrowing the entire park. Trees, grass, the pavilions, and small buildings were crushed and pushed aside by his growing bulk. His tail dunked into the river and changed its course. The sound of his muscles growing was a constant rumble in the air now, and he needed more! More size, more bulk, more power!

He reached back into the crowd of furs, as the feeling of them rubbing and worshiping his every inch they could reach was losing its luster. Just the feeling isn't enough anymore. Now he needed them in their entirety. He grabbed a handful, getting about ten furs in his hand. He soon brought them back up to his maw and he slid out his long, broad tongue. Zahn's tongue flopped out like a pink carpet, and he dropped the furs onto it. At this point now, aside from a gryphon's feathery feel, all of them just felt like fuzzy meat to his body. Then, he slid his tongue back in and swallowed.

It was like swallowing grains of salt.

Zahn's body bulged again as he began absorbing the smaller furs into him. He started to suck in their very life energy into his body. Some of the furs rubbing at him would feel their bodies start to get stuck and pulled. The power of the german shepard was adding them to his body in any way they could. He grabbed another handful of furs and then, with his other, tugged on the rim of his sheath. The macro giant then began to stuff the assorted collection of furs into that tight, musky container, feeling them slide down and bounce on his scrotum.

That felt good. Zahn began to wag his tail, knocking over cars and buildings behind him without a care in the world. He grabbed and scooped up more of the disperting crowd and brought them up to his cock slit. At least fifty furs were sprawled along his hand before he turned it to the side. Some tried to grab onto hairs on his palm, but all of them were soon falling and sliding into the dark abyss that was Zahn's cock slit. Only a few even hit the walls of the eighty foot dick as they tumbled down and splashed into his cum pools. They too, were quickly absorbed into the expanding canine.

Zahn soon pressed his feet together around more of the crowd, and felt the small micros get absorbed that was as well. His toes wiggled, and then, he felt it again. More energy, from the air, from the planet, coursing into his body. He didn't even have to actively try anymore, as he had gotten so large that even the latent electricity in the air was flowing into him, powering his growth. The small crowd was gone, and Zahn was over two hundred feet tall.

But still, it wasn't enough.

Zahn needed more. He moved onto his hands and knees and grabbed up at pieces of the pavement and city around him. His fingers dug into the road and started pulling it up and towards him. The streets started to stretch like taffy, and Zahn started to chomp on it. Sidewalks and roadways pulled towards him as he munched away, with cars and trucks rolling towards him as he picked up the road by its ends and hoisted it towards him. Furs caught in their vehicles and stuck on the sidewalks were sent careening towards the open, gaping maw, and were quickly devoured.

The german shepherd expanded and grew again, his body straining from the feeling. Muscles upon muscles expanded and bulged outward, and soon he got back to his feet. Zahn was as tall as the tallest buildings in the city, and still growing. A single light step of his foot was enough to cover an entire city block. Every fur that was caught, even by the slightest bit of hair on his body, would find their energy drained into him, taking them completely.

Zahn took a heavier step. This time it created an earthquake, tearing apart roads, buildings, and digging into the crust of the planet. The crust breaking was releasing more energy from the planet, and Zahn quickly took that for himself as well. His feet expanded, toes pushing outward and crashing into everything to destroy it. From his feet, the energy and power continued to flow upward, making his muscles expand and grow, increasing his height and thickness.

Before it was too late, Zahn reached down and scooped up as many fleeing furs as he could, crashing into buildings and tearing up the streets to gather them up. Tens of thousands of furs were soon in his hands. Horses, wolves, lions, dragons, gryphons, otters, bears, anything he could image, he could see in the city-sized crowd he had collected. Zahn soon began stuffing them into his body. He tossed them into his maw, stuffed handfulls into his seven hundred foot cock, and even pressed thousands into his big meaty pecs, squeezing them tightly together to be absorbed by his muscles. Their shouts were drowned out by the deep, bellowing sound of the german shepherd growing larger still. The city was now only as big as his big toe, and completely devastated. There wasn't a single fur left there that wasn't absorbed into him, adding more fuel to his size and growth.

"Mmm...thirsty now." Zahn said, looking down at the countryside at his feet, barely able to see past his pecs.

There was a football stadium nearby. Zahn walked towards the great dome and, with a single move, pulled it out of the ground. Then, Zahn took a few steps towards the horizon, his feet leaving scars on the planet as he walked, making more energy free itself from the planet to be absorbed into him. He soon reached the ocean, and dunked the stadium under the surface. After pulling it up, he brought the dome to his lips and began to drink. It was like drinking out of a thimble at this point.

"Meh, too small." Zahn said, before just crunching the football stadium into his furry chest.

The macro canine soon brought his muzzle to the ocean and began to drink. Whirlpools of water flowed into his muzzle, countless gallons vanishing by the millisecond. Tanker ships, battleships, aircraft carrier, all were caught in the vortex of the thirsty canine and sucked beyond his muzzle. The planet's water levels began to drop visibly around the world in a matter of minutes. In five minutes, the seas had emptied, and Zahn was now the size of a continent.

"URRRRRRRRP!" Zahn belched out, the shockwave of the massive air blast hitting the moon overhead. The powerful shockwave crashed into the orbiting satellite and broke it apart like it had been hit with a super weapon.

Broken and burst pieces of the moon fell out of orbit and began gravitating towards the massive blue and white macro. With a grinning smirk, Zahn tugged at the edges of his cockslit and began sucking the pieces into his manhood. Each suck made his shaft larger and larger, the huge canine cock wobbling and oozing pre, flooding nations and washing away the land as it flowed from his slit. By the time all the pieces had been consumed, Zahn's nuts were each the size of a hemisphere.

"Fuck, I'm super horny." He muttered to himself, before getting back onto his feet on the ruined planet. Everything on the side he had been on was devastated, with the remaining population of the sphere on the other side of the planet. Zahn really needed to get off though. But, then he had an idea.

The shep bent his knees and tensed up. Then, with all his strength, he kicked off the planet, jumping high into the sky. In under a second, he broke the gravitational pull of the planet, now making it orbit his body. The shep went wide-eyed for a moment, as out in the vastness of space, there was far more untapped and potential energy then what had been on that useless, formerly blue orb that he used to call home. The sudden surge of growth and power that he was experiencing from being out in space was making what he felt before feel like nothing at all.

The planet was soon reached and gripped by the gigantic german shepherd. It was hardly worth calling it a planet at this point. No, to him, it looked more like a fuck toy. He grinned, and soon lowered the brown and green sphere towards his junk, before he slammed his canine cock upward and pierced into the ball of dirt.

Massive cracks and fissures erupted all over the planet, the hot magma core of it feeling like a heated pad along his throbbing shaft, and the solid iron ball that was the true core slipped free of its equilibrium and rolled down his cum tunnel. The shep didn't care though. He started thrusting harder into it, forcing the planet to take more of his cock.

It was like a virgin tailhole. Each thrust stretched it more, ruining it, breaking chunks of it off which were absorbed into his shaft. Every volcano erupted, magma flowed out of every fissure. It was the literal end of the world, as Zahn fucked and burst the planet, soon shoving his dick entirely through the sphere. His thrusts didn't stop though, they just got more heated and frantic as he gripped the two hemispheres and slammed into it. He was getting rougher and rougher, before howling out into the depths of space.

His orgasm hit hard, as gigantic sperm and cumshots flooded out of his massive cockhole. The rumbling of his shaft and knot tore the planet to pieces, leaving it as dust, crumbling around his manhood before becoming space dust lodged in the fur of his nuts. The throbbing cock erupted out through the vastness of space, and each blast moved faster than light. A torrent of cum crashed into the rest of the inner planets, destroying them instantly, and flooded to the sun. The great gas ball was extinguished by cum, the fires and reactions going out as his seed soaked into it, putting it out.

Not only that, the more Zahn was cumming, the larger he was getting. The energy he was releasing by having this orgasm was flooding back into him, making a feedback look that was making him bigger! Before long, his feet were crashing into the other planets, his pecs were pushing into other stars, and his dick was swallowing up more of the fabric of creation. He soon was pushing out of the galaxy that used to house his home planet. The multitude of stars and clusters were absorbing into his body, sinking into his dick, and swallowed down by the massive canine.

Light itself couldn't escape from Zahn now, as his body was reaching sizes so huge, that other nearby galaxies were shifting out of the universe's expansion towards him. He licked at his muzzle, grabbing those untold numbers of stars and planets and stuffing them into his body. Each galaxy that fed him, all that energy, made him even larger.

It wasn't enough.

Zahn lustfully grabbed at more galaxies. The energy they held, it was starting to slow. Even pushing multiple down his dick wasn't giving him the same boost that it did before. But he didn't stop. He grabbed more stars, more galactic clusters. He was even able to grab black holes out of the fabric of space. Those gave massive boosts, but soon he began to run out of them as well.

He needed more.

The german shepherd began to grab into the very fabric of the universe itself. The great black void felt like velvet in his hands. He began swallowing it in every conceivable notion. He ripped chucks out into his teeth, stuffed handfuls of it into his dick, going so far as to shove his own arms into his cockhole to submerge it into his sac. He pulled more of it into his body, pecs, rump, everything. Everywhere.

The edges of the universe started to fray and break. A sudden and powerful crack rang in his ears as the barrier, constantly and infinitely expanding, was overtaken by his own constant and infinite growth. All of the energy from shattering the barrier of the universe was pulled into him. He howled out, feeling all of everything, creation, all that was known, flowing into him.

Zahn took a moment to catch his breath, the sudden exhilarating rush hitting all at once upon the realization that he had absorbed the universe itself. Just the thought of it was getting him hard again. But there was nothing left to fuck. He was all. He had done it.

But he still didn't feel satisfied. Like there was more.

He looked around. There was a void of white all around him. Zahn was infinite in all directions, and expanding infinitely. But then, he saw it.

It was small, like a clear and transparent screen. A slight glow came from it. The german shepherd eagerly rushed towards it, wanting to make it part of him. To fuck it, to consume it, to be it.

He reached out towards it, grabbed at it. His hands felt it, like touching a glass window or monitor. He was a bit confused, and looked towards it. There was someone on the other side. Someone watching. Someone that had watched him grow to this size, and was watching him now.

Zahn reached out, bringing a hand to it, but couldn't quite grab it. It was like some sort of barrier between dimensions. But, even now, as he was still growing infinitely, he could feel it start to weaken. He grinned.

"So, you liked what you saw huh?" The german shepherd addressed those watching him, "Well, you'll really enjoy the next part. You're next. It's only a matter of time, before you're mine."
