Gift Story: Mega-Muscle Master Chief

[rdalrt2]

This is a gift story for Muk100, who wanted to see a growing Master Chief with no size limit. Let me know what you all think.

------------------

Twigs and brush crunched loudly under the feet of the armor-clad Spartan as he walked through the alien world's forest. The green armor glinted in the fading sunlight of the binary star system, this ancient yet artificial world eerily empty.

"It should be two kliks north of your position, Chief." Came the voice of his longtime guide and companion, Cortana. The AI wasn't embedded in the Spartan's helmet as per usual, instead it remained on the dropship that he'd arrived on, giving him direction from afar. "Don't let your guard down...it wasn't a message like anything we've seen before. Not a human or Covenant signal source."

The soldier continued plodding through the forest, his keen senses keeping watch for anything suspicious. A few hours ago, a message had been broadcast from this location. It was a repeating broadcast, with a robotic voice that sounded eerily similar to less-than-friendly AI that Master Chief had encountered in the past. It said simply, "A universe-wide extinction event will occur without The Reclaimer's intervention. The Reclaimer must find the source of this message if the universe is to be saved." The chief had heard that title assigned to him before, it could only mean him. He elected to drop in alone, figuring that he didn't want his fellow soldiers to die if he was walking into a trap. As he continued to hack his way through the thick tree line, he found it opened up into a broad clearing, as if the trees were bowing in reverence to the structure that sat in the clearing. It wasn't a massive building, but it was quite impressive.

It looked to be a temple of some sort...clearly it was a Forerunner building, left by the creatures that constructed the Halo array. Its purpose was a mystery, it certainly didn't look like a weapon. With his rifle drawn, Master Chief ascended the stairs to the entrance, checking corners and ceilings. There was nothing, he was completely alone in the building. Its main antechamber was quite barren, there was only a cylindrical protrusion in the center. As he approached it, the cylinder opened up on one side, revealing itself to be an elevator. Suspicious, but curious about that message and what it meant, the Spartan walked inside the elevator, and the doors closed before it began to descend. How far he was going down, he didn't know. But the elevator was moving at a pretty good clip.

"Cortana, any more intel about this place?"

"No, Chief. We're completely in the dark. Watch your back."

Feeling no better once the doors opened, the Spartan looked around the room he'd been delivered to. He was expecting some kind of stone temple interior, but what he found instead gave him pause. It was a globe-shaped room with a holographic star chart covering the walls, so huge in scale it was about the size of a sports stadium back on Earth. And in the center was a long walkway, a circular platform containing a large computer terminal. He approached the terminal, watching the chart shift and move about on the walls. Once he reached it, a robotic voice rang out through the silence.

"Greetings, Reclaimer. I am 103 Revenant Star, Monitor of this installation." The Spartan was reminded of his previous dealings with 343 Guilty Spark. That had not ended pleasantly, and he hoped this would be different. "No doubt you've come here in response to the signal I have been broadcasting. Time is short, so I will be brief. You have proven yourself quite capable at defeating Flood forms, even a Gravemind was powerless to stop you. But you have only dealt with a relatively young Gravemind, Reclaimer. The threat you now face is a Gravemind that is thousands of Earth years old, and has consumed every life form in its galaxy."

That made the human stagger a bit, could it really be true? A Gravemind that had devoured and integrated every bit of organic life within the entire galaxy?

The AI continued.

"I was created to monitor several galaxies and star systems, watching for an event such as this. This Gravemind is outside the range of the Halo array, and no similar system exists in that galaxy. The galaxy that has been overtaken is a very long distance away, approximately 18.3 light-years away. There is only one way of defeating it, and you must do it, Reclaimer."
"How do I do that?" The chief asked flatly, not even bothering to question if he could do it, or if it were even possible. He could do it. He would do it.
"You must become our sword. Strike down the Gravemind with your power, and ensure that it does not spread to the rest of the universe. You will be transported to that galaxy, but be forewarned: there will be no returning. I only have enough power to send you there, and you will be in no state to return anyway. Do you understand?"

The chief nodded, he didn't even need to think about it. Being stranded, unreachable by anyone or anything was a small price to pay if he could extinguish a threat to the entire universe.

"Chief, you can't seriously be considering this. We don't know anything about that Gravemind, this machine could be wrong, or the AI could be rampant and lying! It's too risky!"

"I can understand your doubt, but time is short. Each passing second, the Gravemind grows more powerful and extends its reach to new star systems and new galaxies. The time approaches when it will be beyond the capacity to be defeated. Only by becoming our weapon can the Reclaimer prevent this. His sacrifice will not be in vain, he will have fulfilled a soldier's duty of protecting his people from annihilation."

There was a brief pause, during which the chief pondered the options. His superior mind worked quickly, deciding that this AI could be trusted, and that the threat at hand was as real as it claimed.

"What do I need to do?" Master Chief asked without a hint of shakiness in his voice.

"You will enter the preparation chamber at the bottom of this facility. There you will be made to survive the vacuum of space, and prepared for your conflict with the gravemind. You will be placed into a containment capsule, and enter Slipspace, arriving at the ideal location to combat the gravemind."

The Spartan nodded, prepared for his final duty.

"Chief...are you really going to do this?"

"I have to. I'm sure you understand."

There was a pause before Cortana responded, sadness in her voice. "I do. It was a pleasure to serve with you, Chief."

"You too, Cortana." And with that, the soldier reached up to his helmet, turning off the communicator. He looked back toward the AI that commanded the console and nodded. "I'm ready." The elevator that he'd ridden down here opened again, the AI speaking with urgency in its voice. "You will descend into the preparation chamber. There is no time to waste."

With a nod, the Spartan walked into the elevator and began to descend once more. He was going much further down than he did last time, at such a rapid speed he was nearly freefalling. Deeper and deeper into the planet he went, the elevator finally slowing to and opening up to reveal a large pod-shaped device, with its hatch open. "Get in. This will prepare your body, and take you to the Gravemind's location." The AI said, its voice coming from all around the chamber. Master Chief walked up the small staircase and climbed into the pod, the hatch shutting behind him. He was left in darkness for a moment before a soft amethyst light began to pulse inside the chamber. His skin started to tingle, and his hair was standing on-end. That light was doing something to him, it wasn't just a simple scanner.

"This is one of the last great creations of the Forerunners. Deemed too dangerous to use, even more destructive than the Halo array, it was sealed away in this temple. It was to be used in only the most dire of emergencies, and a galaxy-spanning Gravemind is indeed a threat to the entire universe. Your body will undergo drastic expansion and mutation to fight the Gravemind." Hearing that made the Chief's body shiver a bit, the machine working on him.

"What kind of mutations?" He asked, curious and a bit apprehensive.

"A massive increase in your musculature. You will destroy the Flood with your bare hands." The chief nearly choked at hearing that, how was that even possible? "The preliminary adjustments are complete. The device will now propel you through slipspace to the Gravemind's location. The fate of the universe rests with you, Reclaimer." The AI said before falling silent. The chamber began to hum and vibrate, and the chief could tell he was moving.
Around the planet's orbit, the carrier that had taken the chief to this planet was still orbiting, awaiting orders. From the bridge, everyone inside saw a bright streak blasting from the center of the planet, and the telltale shimmering of the local area that came with a vehicle's entry into slipspace. The chamber containing the Spartan rocketed away from the planet, diving into the tear in space it had created. Meanwhile, the Chief had begun to feel quite warm inside his armor. Curiously tensing his chest, he felt it strain against the confines of the suit, something that his muscle had never done before. He realized he was going to outgrow his suit, and likely this pod in short order! The slipspace jump was taking a long time, longer than he was used to. He figured it was because he was travelling so much further than the slipspace drives he'd used in the past. The ships he'd known could only jump between star systems, this one was rocketing him into an entirely new galaxy! The astronomical details were fascinating, but not the Chief's top priority at the moment. He winced a bit as he felt his manhood starting to grow cramped inside his armor. He'd never been small in that department and his armor had been crafted to be nicely 'roomy' for him, he now felt like he was squeezing into a too-tight jockstrap. The feeling was the same all over, his arms and legs and torso straining to be contained by the armor. With a grunt of frustration, he flexed his biceps, watching as the plates of armor began to crack and tear apart. That was it, he had to flex his way out of the suit! Taking a deep breath, he puffed out his chest and tensed his back, the chestpiece of the armor coming off and falling to the floor of the pod, exposing his thick, growing pecs. He reached a curious hand up to feel them, and even through his gloves he could feel how much bigger and stronger his chest was. The only thing that didn't feel any tighter on him was his helmet, maybe his head wasn't growing in proportion to the rest of him. He flexed his arms once again and finally managed to tear off the armor containing them, taking his gloves off quickly. His torso and hands were finally free, and he began to explore his swelling chest, rubbing over his pecs curiously. He was so muscular, so profoundly bulky he couldn't believe it! Little did he know it was just the beginning of muscular journey.

Once his hands were free, he was able to remove the remaining parts of his armor with greater dexterity, discarding everything but his helmet. Standing nude in the capsule, he couldn't help but admire his hulking form, rubbing across it, feeling the bulky contours of his muscle. He groaned as he rubbed along his thickly-cut abs, squeezed his massive thighs, and gently gripped the base of his expanding manhood. He'd been quite large before, but right now his soft shaft was quickly approaching his knees, growing as thick as his wrist! Draped over a pair of balls that were bigger than navel oranges and still growing, his shaft pulsed with excitement as it began to thicken and stretch upward, the chief getting a bit lightheaded as he achieved the biggest erection of his life. With one hand stroking his shaft and the other roaming through the hairy expanse of his swelling chest, the chief began to make the most of his time alone in the rapidly-shrinking enclosure. As the capsule gave a bit of a jolt, the massive Spartan remembered the circumstances surrounding his sudden growth.

He felt the vehicle leaving slipspace; he must have arrived. The capsule began to slowly break in half, splitting open down the center. At first, the mighty soldier panicked, seeing the air inside rush out into the cold vacuum of space. But he remembered what the AI had said; he would be made able to withstand this. He looked around curiously as the halves of the capsule and his broken armor began to drift away, leaving him naked and floating in a seemingly-infinite void. He no longer needed to breathe, and somehow he didn't feel particularly cold even with his skin exposed to space. What the hell had been done to him?

With the pod gone, it was just his naked form floating through space. His eyes adjusted to the dim light from the distant star, looking at his empty surroundings. He didn't have much time to admire the scenery; the changes in his body were getting more intense. Now free of the confines of the pod, his growth came even faster. His shoulders widened and rounded out, his traps rose up along the back of his helmet, his chest pushed out even further into his horizon. He really was mutating now, beyond the bounds of what he thought was humanly possible. Was he even human anymore? Passing 10 feet tall and half a ton of brawn, he couldn't fathom how strong he must have been. He felt the muscle fibers clench firmly across his entire body, each time flexing and relaxing of their own accord, pumping up larger with every heartbeat.

A pleasant warmth began to flow through his limbs as he continued to expand. It was not unlike the firm pump one got from a hard workout, but this was much more intense. Suddenly he could feel every muscle fiber, every sinew of his massive and growing body. As his mind became more receptive to the growth, he found that it came faster. As he passed 20 feet in height and 4 tons of hairy brawn, he embraced the sensation of growing. He still wondered how he could fight the Flood with just his body, but he had faith in the AI that had done this to him. It was starting to feel very pleasurable, as evidenced by his shaft growing and thickening, starting to leak pre into the depths of space. He'd never imaged having a cock so big; it was wider than his wrist and reached up to his fat, fleshy nipples. And it was only growing bigger!

The soldier's powerful hands gripped the base of his cock and began to pump firmly, sending shivers of pleasure up his spine. Having so much more flesh to work with felt amazing! Every other thought was pushed from his head as he gripped his cock and started to stroke it rapidly, his slippery pre lubing up the shaft for his calloused hands. Bigger and bigger he swelled, after a few minutes of this he found that his hands didn't cover as much cock as they used to, and shortly after that he had to use both hands to reach all the way around it! Even then his fingers barely touched. As he passed 30 feet and 17 tons, his cock was so massive that it reached up towards his eyes, nearly as big around as his waist. Part of him wished he was in a place with gravity just so he could feel how heavy his massive balls were, they felt as big as pumpkins between his legs! His stroking resumed with vigor, he felt himself rapidly approaching his climax.

His hands flew over the surface of his growing cock faster and faster, and his entire frame jerked as he felt a deep clenching in his massive nuts; the point of no return had been passed. Fireworks exploded in his mind as he experienced the first climax with a shaft so monstrous. But it wasn't just the orgasm that was contributing to this bliss. His growth reached a new level as he began to cum, his head spinning as he grew by nearly five feet per second, untold hundreds of pounds piling onto his frame. He moaned and panted and thrashed out, spraying seed in every direction in the void of space.
After several long moments of his brain-melting orgasm, it began to slow to a trickle and finally ebb away, leaving the helmeted soldier panting and sweating from the sheer intensity of it. He thought jerking a ten-inch cock felt amazing but this was an entirely new level of bliss. Now that he had a shaft that towered over his head, it was hard for him to think of much else. But something would give him focus very soon.

His presence in the galaxy hadn't gone unnoticed. The gravemind that had taken control didn't take kindly to this intrusion, and sent a swarm of infection forms in the chief's direction with the intent of adding him to the galactic infestation. He saw them coming, a grayish, brownish cloud of Flood streaking towards him. Now the real work would begin, he thought. He'd have to find a way to defeat the infestation in this galaxy. Improvising, he pulled one colossal arm back and balled his hand into a fist, timing his punch just as the first wave approached. To his surprise, his fist flew right through the center of the swarm, and he didn't feel it connect with a single one! What he did feel was a distinctive tingling sensation, along with his growth increasing in rate once again. Pulling his fist back quickly, he saw that he had indeed punched a hole through the swarm of Flood, but where had they gone? The answer came to him as the swarm descended upon him, trying to infect his massive, growing frame.

One by one, as the Flood touched him, they simply vaporized. The chief watched one latch onto a massive pectoral, and even before it could ready its probe, it was gone. It seemed to simply melt into a pile of goo, which was quickly absorbed by the growing demigod's skin. That tingling sensation returned in full force, and he couldn't help but moan as he felt himself growing faster and faster. The physical matter that made up these infection forms was being broken down and added to his own mass! Within seconds, the initial cloud that had descended upon him was gone, each one absorbed, having added 25 feet and several dozen tons of mass to the Spartan. He looked into the depths of space, his enhanced eyes focusing on another, bigger swarm approaching him, about ten times the size of the former one. With a grin, he simply spread his limbs wide, trying to make himself look as appetizing as possible for the Flood. As predicted, they collided with his swelling frame, and were devoured by the mutated human's skin instantly. He shuddered in bliss as he grew and grew, realizing this was how he'd fight the Flood in this galaxy. He'd simply grow so massive that he'd absorb everything they could throw at him!

The gravemind would not be beaten so easily. As it watched the chief swell up past 400 feet tall, it tried a new tactic. The galactic-sized infestation had claimed many societies in its wake, along with their technology. The chief turned as he saw the telltale vortex that signaled a ship leaving slipspace, and watched with no small amount of awe as an armada of Flood-infested spaceships emerged, each one dwarfing the ships he was used to seeing. There had to be thousands, the entire naval might of a civilization harnessed by this gravemind. All at once, they trained their blaster cannons on the chief and unloaded a cascade of brightly-colored beams, each one hitting the swelling Spartan dead-on. If he could absorb matter, the gravemind reasoned that he couldn't absorb energy.

As Master Chief roared with euphoria, the gravemind was proven dearly wrong. Energy was just as easy to absorb as matter. As soon as the multitude of beams made contact with his exposed skin, Master Chief's growth skyrocketed. His body grew eight times larger in an instant, and then grew ten times larger than that! His mind reeled as he passed 35,000 feet tall, his muscles so colossal that his head looked to be a tiny speck atop a mountain range of brawn.

Surely there had to be a limit to his absorption abilities, the gravemind reasoned. It just had to overload the Chief's body with energy and destroy him. To that end, the beams that were firing out of the ships grew brighter and more intense, their power output climbing steadily. But as they continued to fire, Master Chief kept growing. He couldn't even fathom how rapidly he was growing, or how large he was now, it was simply too much! His shaft towered over his head, leaking pre into the depths of space, the Spartan laughing madly as he swelled beyond 100,000 feet tall.

"You're only...making me stronger..." He chuckled to himself as he kept growing and growing. As the ships began to overload their reactors and explode, the gravemind hatched another plan. One of the worlds that the Flood had overtaken was quite adept at manipulating gravity. They had managed to build gravity pumps that could direct the flow of it in massive scale. The technology had been used to create and sustain colossal orbiting cities, mining platforms, and solar arrays. Of course, it had been a few thousand years since the Flood over-ran the world, but the gravemind had kept some of the equipment running smoothly. From the surface of a planet too far away for the growing chief to even see, a colossal cannon-shaped object was being aimed. With a deep, vibrating hum, it fired off into the depths of space, right at the swelling colossus.

The chief felt his body lurch in space, being propelled by some invisible force. He thrashed his massive limbs around to no avail; he was headed somewhere. Rather than risk letting him absorb too much and become too powerful, the gravemind would simply dispose of him in the way it disposed of many things. The chief felt a warmth on his back as he floated, maneuvering himself to see where he was headed. When he turned to face the source of that warmth, his visor was filled with the blinding light of a star, a rapidly-approaching one at that! If the gravemind couldn't destroy him with cannons or Infection forms, it would simply toss him into a star and vaporize him in nuclear fire. The chief struggled as he fell closer and closer towards the star, caught in its own gravitational pull now. Surely he couldn't withstand this! The gravemind felt a sense of satisfaction as the Spartan's massive form fell closer and closer to the star. Even as huge as he was, his body was lost to anyone observing the star, a tiny speck being flung into it, never to be seen again.

Or so the gravemind thought.

The chief did indeed feel a burning as he approached the star and fell towards it, but it wasn't the sensation of his flesh being seared. The gentle warmth that he'd felt initially, the beginnings of his growth, had turned into a raging blaze inside him. A gasp caught in his throat as he collided with the surface of the massive ball of plasma, his bare skin touching the star. Almost immediately, a crater formed where he landed, all of the mass and energy being transferred right into the chief. He closed his eyes and grit his teeth, but not from pain. It was concentration. He was trying to hold back the unstoppable inferno that had been created inside him. His frame trembled for a moment, but it felt like an eternity for the massive Spartan.

"No...too much..." He moaned, but there was no stopping it. A visible shockwave formed around his body as he simply detonated with size, roaring to the distant stars above as his body stretched out in all directions, faster than his eyes could perceive. The growth from the beams before had been child play! He'd been nearly 130,000 feet when he tossed into the star, and a moment after he made contact, he was more than 2,000,000 feet tall. His body swelled and bulked out, his chest whooshing out, further and further away. His shaft reached higher and higher above his head, now twice as big around as the Spartan's waist and still growing! His body grew several times bigger every second, and even then, he'd just made a dent in the star! More and more energy and plasma poured into his body as he increased his surface area. 4,000,000 feet, 9,000,000,000 feet, 15,000,000,000 feet and climbing!

"Can't...stop...growing!" He roared to the silent stars as the incredible rate of his expansion nearly crushed his consciousness. But he was a warrior, he would endure. Unable to fathom or even see what was happening, his vision became nothing but a blinding light. The star began to quickly vanish as it was replaced by a growing, pink-skinned colossus. In the span of about thirty seconds, the star was no more. Master Chief had unwittingly absorbed its entire mass and energy content. He had done something that not even the galaxy-spanning gravemind could accomplish, he had devoured an entire star! Once he'd gotten his bearings and began to think and see more clearly, a deep, ominous chuckle escaped his throat as his musclebound frame floated in the center of the solar system. The star had been a rather large one on the cosmic scale, nearly eight times the size of Earth's sun. The chief's height was now best measured in miles, looming over the remaining armada of ships at more than 73 million miles tall. His mind spun with power, his muscles were cosmically-huge, and he felt a deep need to grow again. He had to get bigger, there was still so much more galaxy to absorb, and he had no idea what else the gravemind could throw at him. Plus it was just so damn addicting, the feeling of growing mightier, more powerful, more endowed. Concentrating for a moment, a deep rumbling shockwave pulsed out from his body, his massive frame sending a pulse through the rest of the solar system. One by one, the nearby planets came streaking towards him, compelled by his power to add more mass to his body. They crashed into him, one by one, and were absorbed into his almighty girth.

"This is it..." He whispered to himself, trembling with delight as his muscles blasted out bigger, huger, more powerful. He was going to be a muscle-god. He would end this gravemind, and then ensure that nothing like it could ever exist again! With a deep moan, another, more powerful shockwave emanated from his impossible bulk. It reached out past the solar system, to the nearby systems of the galaxy. Master Chief grinned excitedly as he watched more planets, more Flood-infested ships, and even other stars rapidly drift closer to him, crashing into his frame and being absorbed by it instantly. His laughter boomed out through the galaxy as his size exploded, growing magnitudes bigger every second! 200 million miles came and went, then 500 million. One billion, three billion, nine billion, it just kept getting faster and faster!

"NO! You will ruin everything!" A voice screeched in Master Chief's mind, no doubt the gravemind trying to save itself. From every vantage point that the gravemind possessed it watched the chief's body outgrow the solar system, absorbing more and more!

"Bigger..." Was the chief's only response as he swelled faster and faster, 20 billion miles tall and growing! There was still so much more to absorb, so much more galaxy to fill! The gravemind felt its power diminishing as more and more of its symbiotic forms were absorbed into the chief's body. "More! I need more!" He concentrated as the nearby solar systems began to drift toward him, he'd already absorbed six stars and was eager to absorb the rest of the galaxy, more than 250 billion stars! His focus was unparalleled, and the gravemind grew more and more desperate, throwing everything it could think of at the growing god. Toxic agents, more infection forms, more powerful ships with more destructive weapons, none of it made any difference and only served to grow the chief faster.

By this point, his muscles looked freakishly large, so huge that it was a wonder the chief could move his limbs at all. One would have to look very, very closely to see his helmeted head atop those mountain ranges of shoulder muscle. His pecs pushed out so far in front of him and hung down so massively they were nearly past his navel, each one capped with a huge, meaty nipple. His abs were incredible, many men coveted a 6-pack, but Master Chief had a 16-pack. His waist looked rather slender compared to the monstrous swell of his lats, but he was by no means petite. His legs were each nearly as thick as his entire torso, packed with corded power. But as massive as his body was, his manhood had grown into an unbelievable leviathan of flesh. Similarly to how one would need to look hard to see his head atop his muscle, from far away, the same task was required to see the body attached to the massive shaft and pair of stones that were drifting through space, absorbing everything nearby. From a distance, Master Chief looked to be a colossal set of genitals and nothing else, that was how massive he'd grown!

"And I just started..." He chuckled as he concentrated once more, pulling the contents of entire solar systems towards his body with a mere thought. He was more than 400,000,000,000 miles tall now, the gravemind's power growing weaker and weaker as more pieces of its hive-mind were absorbed. 700,000,000,000 miles came and went. 1,000,000,000,000 miles tall was easy. Passing an entire light year in length, more than 5 trillion miles, he could only reflect on how trivial it was to grow like this.

"Bigger...more! I'm going to fill the whole galaxy!" His voice boomed out through space, dusting a few planets just from its sheer force. Despite its near-infinite cognitive power, the gravemind could see no way to escape its fate at the hands of this colossus. At the rate Master Chief was growing, he'd absorb the entire galaxy within minutes, and the gravemind would be no more.

Time ticked by, and Master Chief only grew faster and even more colossal. 10,000,000,000,000 miles. 24,000,000,000,000 miles. 85,000,000,000,000 miles. 170,000,000,000,000 miles. "Grow, grow, grow..." Master Chief repeated the mantra in his head as he let himself erupt out into the galaxy, his consciousness a blinding surge of primal power. He lost track of time, there was only the present moment, the feeling of exponentially-swelling power.

Finally, it was done. The gravemind's galaxy of hive minds had all been absorbed. Not a single mote of dust remained in the galaxy, everything had been replaced by the Spartan. He smiled proudly as he flexed the infinite muscle at his command. His chest surged out hundreds of light years in front of him, his shaft magnitudes further than that. His mind reeled with information and knowledge. In absorbing the gravemind, he'd gained everything that it had seen and known. An entire galaxy's worth of knowledge, resting in his mind. He was nothing short of a god now. And yet, despite his accomplishment, he didn't feel particularly sated. After all, one galaxy was nothing in the grand scheme of things. Surely a few more couldn't hurt?

And so the laughter of the chief resonated through space once again, another shockwave pulsing off of his body. The forerunners had created him as he was now, molded him into a galaxy-destroying god. And he was a hungry god.

I'm not familiar with the "Master Chief" character or storyline, but this was fun and hot :-)

[muscl4life]

HOLY COW!

That was an incredibly amazing growth story. The size descriptions were mind-blowing and the galaxy-sized muscle monster was just POWERFUL!

Congratulations, dude! You certainly have the gift of macromusclegrowthphilia

[droz]

The "Master Chief" is from the Halo series of games and animated movies

[rabiyya]

Ah, thank you, Droz!

[Muk100]

thanks for the story again
hope you make more

[giantw]

Well I liked it. Nice MEGA story for your initial outing.

[kettlecharlie]

Great story
Thank you
Of course I started reading it under a misapprehension-- I thought it was about a Master Chef, making special cakes for muscle growth
Soon learnt I was wrong
A thought-- now you have managed the superhero fantasy and very well too-- why not try something a bit more down to earth-- to extend your range
All the best
