For Bigness' Sake

A flash of light filled the training hall, blinding the tall, powerfully-built, golden-armored digimon as he swung a hand-weapon made of golden claws at a beat-up training dummy. He shouted in surprise, his deep voice drowned out almost immediately by a delayed blast of such magnitude, it shook the mostly empty training hall around him. Weapons clattered against each other, dummies fell over, the sensory overload knocking the digimon off of his digitigrade feet and onto the floor, banging his masked head on the ground.

His senses returned slowly, blinking his bright blue eyes through the golden mask he wore as he looked around. Another big digimon stood over him, looking down in concern. "Are you alright, brother?" He asked, blinking his own blue eyes through the golden mask on his face, white feathered wings giving a flex on his back.

It took LD a few seconds to respond, looking down at his white-and red flesh, the golden sheen of his armor. Nothing seemed out of place, and he certainly didn't hurt anywhere. Sitting up slowly, he took his massive brother MM's outstretched hand and helped himself onto his feet. "I feel okay brother, what happened?" He asked, looking around to just be sure that nothing had changed in the moments that he had been unconscious.

"I was studying a new tome in the library, brother," the black-and-red digimon replied, scratching the back of his head through the thick mane of red hair that came out the back of his golden mask. "I must have made a mistake when I was trying one out, I don't even know which spell it was..." He finished uncertainly.

LD shifted uncomfortably, his armor feeling a bit tighter in places, long thick tail swishing from side to side in agitation. "Should we try and find out what it was? It could have been dangerous!" he replied, in some concern. He grunted as his chest began to feel squished in his armor, making his blue eyes widen in surprise.d

His brother digimon grunted a little as his big red abdominal muscles suddenly seemed to contract, making him bend a little. "What the...?" He grunted again, gripping the bright golden metal of his codpiece as it suddenly popped off. LD gasped in surprise as his brother's genitals were revealed, a substantial pair of heavy balls with a thick member laying over them... and they were growing before his very eyes!

"LD!" his brother suddenly gasped, looking at his brother in surprise. The gold-armored digimon grunted as suddenly his precious metal plates began to split and crack, the tightness having increased phenomenally in the few moments that they had been standing there pondering the nature of the incident. Bits and pieces of the polished metal clattered to the ground, revealing more and more of the sculpted digimon beneath, making him blush as all of that musculature began to grow, expand, swell incredibly.

Both digimons groaned loudly as they watched the other expand visibly, inches adding to their height. MM tried to hide his growing endowments too, his hands becoming useless to hide the huge swells of his balls and veiny shaft as it grew enormously between his tree-trunk legs. The sight of those growing treasures caused LD to become aroused, smiling through his blushing mask as his own codpiece nearly exploded from the powerful tightness of his own swelling groin. The metal codpiece fell to the floor with a bang, revealing a massive throbbing erection.

"Oh gods above, it feels so good, brother," MM growled softly to his twin sibling, both of them now completely nude except for their golden masks which stayed in place despite the incredible growth of their bodies below. "I... can I touch you?" The darker digimon blushed heavily as he reached out a meaty hand to rest it on LD's muscular sides, feeling them grow under his paws, feeling the muscles stretch and swell.

The lighter digimon flexed his wings, stepping into his brother's embrace, his erection grinding against MM's own, both cocks throbbing firmly along the other's girth as they swelled incredibly. The power of the mis-cast spell surging through every inch of those lengths, those balls drooping lower, squishing comfortably along the others' inner thigh in a fight for space between growing muscle and swelling genital flesh.

They were snapped to their senses suddenly as both heads bumped into something hard and unmoving overhead. Both sets of bright blue eyes looked upward in dismay taking in the sight of the training hall's ceiling, never having seen it this close before. LD gasped as he looked down around both of their massive bodies, finally noticing that they were filling the training hall with their ever-expanding forms, there was no way out now. "Oh brother, we're trapped! What do we do? It's getting too tight in here!" He growled uncomfortably as he was forced to sit, his massive masked head and broad swelling shoulders pressing up against the ceiling, his growing form pressing up against the walls and his twin brother.

MM could only grunt in response, in much the same predicament as his twin, fighting for space, pain lancing through his form as his feathered wings were crushed up against the wall behind him. Loud cracking sounds began to fill the air as their forms finally began to pry those walls apart, rubble falling over their bulging muscles and groins, dust filling the air as the building could no longer hold them in, crumbling around them as they were exposed finally to the air outside, gasping for breath as they moved.

They both growled happily as the crowded confines of the building crumbled around them, giving them space to stretch, their huge cocks slapping wetly onto the rubble as they felt their arousals build with their huge bodies. Even once-enormous trees nearby were not match for their bulk, seemingly stunted in the shadows their bodies produced.

"Oh LD..." his brother groaned, rolling himself over to press up against his brother, kissing him firmly through the mask as their growth continued, neither caring if it never stopped. MM grinned widely, reaching down his bulging form slowly until his massive paw slid around both of those growing lengths, gasping as they were like trees themselves, so full and firm.

LD looked on his brother with love, kissing over those gigantic pectoral muscles as his eyes closed in pleasure. He growled at the sensation of his brother pumping those lengths together, feeling their incredible lengths pulsing with larger heartbeats in their chests. He was so close already and he could feel that his brother was too. He reached down to grip at MM's ass, feeling the powerful muscle grow there, especially around his tailbase, swishing with powerful strokes back and forth as his internal muscles tensed up.

Both colossal forms growled and howled in pleasure, arching those meaty backs as cocks the size of sky scrapers began to unload, spewing enormous geysers of seed over each other, rivers of spooge gliding down and over swells and bumps in musculature, running together onto the crushed rubble below and the grass around their forms.

Such a powerful new orgasm left both digimon gasping, panting in joy and pleasure as an afterglow unlike any they'd experienced before began to settle in. It warmed their huge growing muscles, and helped them to relax against each other. Both brothers smiled, trailing their clawed hands through the other's cum-laced chest, feeling the muscles continue their steady growth.
