So Many Sabers(Artoria/Mordred TG) (Patreon)

"Perhaps I should take my leave. The mana required to keep me physical is already-"

"No! I can DO this!"

Shirou Emiya was in a desperate spot, his shaky standing as a master in the Grail War already being challenged by of all people, his own servant. Er, perhaps he should find a different name for her role since servant felt kind of weird for someone stronger than him, but terms could come later. He had already almost died once and Saber now could barely act, her mere presence sapping mana at a rate that felt like he was consistently climbing up stairs. He knew he wasn't the best as a mage, likely not even mediocre, but he refused to be sidelined like this, especially now when he finally had a chance to stay true to his goals as a Hero of Justice. But there was nothing he had to rebuff Saber as she continued to walk.

"Your magic is insufficient for me to use my Noble Phantasm in battle, even now I can feel your body approaching a limit supplying me with a physical form. I do not say this out of ill will for you as a Master, but I have a wish I must have granted and I will not lose this second chance. I have no urge to destroy you. As a king I must know when a battle is lost."

"Wait!"

Shirou's voice sounded weak and full of conflict, his arm sore from the quick Trace he had used to protect himself from Archer, but he raised it anyways as if that would somehow keep her from leaving. But staring at his outstretched hand let his eyes wander, the command seals tattooed on, his mind running through possibilities. Despite his subpar magecraft, he could feel the intense magic resting in each red patch, the feeling that he could even break reality with them almost inherent. He had to show some resolve, prove that he could risk it all. It wasn't enough to sense it though, he had to feel it, Saber bristling and turning on a heel, her face concerned as she yelled out a shocked, "You wouldn't!"

Though their bond was weak due to his limited mana, the recklessness was obvious on his face, Shirou not about to give up.

"I know I'm not the strongest yet, but surely you at one time were where I stood, building your legend through your own two hands!"

Saber wasn't sure whether she should slap him or talk him down, judging the distance between them, annoyed for having stepped outside her range after taking little note of her Master.

"Yes through training and camaraderie, not with a suicidal charge at-"

Shirou knew better than to let her get closer, her fight making it clear how superhuman her movements could be, his left hand raised as he made his command.

"THEN SERVE ME AND MAKE ME A NOBLE HERO JUST LIKE YOU!"

If that was all there was to his plan, Saber would have been annoyed, but worked with it, not entirely against a noble fool like him, but it was the followup she could sense that made her try to stop him, the command seal barely glowing red before her Master gritted his teeth and screamed out, "TRACE ON!"

For a moment, night turned to day, light blinding in its intensity, Shirou's screams matching it as magic swelled far past his body's tolerance. He was still ignorant to the gravity of the grail, his trace attempting to steal a sliver of infinity, a sliver still just as infinite as the whole. It felt like he was being atomized, endless magic through the ages pouring into his vessel, his frame ready to break. There were two reasons Shirou didn't die that second, ground into a speck and absorbed into the greater grail. First was his connection to its future, a time paradox the grail refused to cause, his trace spiderwebbing through the network of the grail's power, his mind rolling about the infinite depths. Secondly was the hilt of Avalon stowed away in his body, its regenerative powers truly being put to the test as the Grail and Avalon both attempted to prevent him from dying, a corruptive paradox spreading.

Two people immediately took notice, Caster miles away wondering why the hell someone was messing with the grail, the rules of it in jeopardy. It kind of broke the purpose of her Rule Breaker if other people were getting in on the corruption, so she did her best to quarantine it to the Saber class, since that seemed to be the one the spell had the most affinity for. The other was Archer, the tanned servant looking vaguely annoyed as his Master Rin argued about the orders he was supposed to follow on their way to Shirou's house. When the night suddenly lit up, Rin jumped, looking around for the enemy mage that could have caused this. As for Archer, he didn't have to wonder the memory searing itself into his head, his essence shaking as the strength left his knees, forcing him to the ground. For a second he thought Shirou had been killed, his tether to reality finally shattered, but as the corruption filled him, a completely different series of sensations filled the servant, equally horrifying as it was, weirdly, arousing.

Shirou's consciousness was at the moment being squeezed out of the grail, historical moments and histories from across the past, present and future appearing in a disorienting montage, each glimpse lasting longer as he was slowly forced out, Avalon releasing wild shocks of regenerative power at every squeeze. He was everywhere, the streets of London, watching a shrinking figure stalk the back alleys, a cramped apartment filled with drawings and charts, a painter rapidly deaging as he looked more and more like the familiar painting he was-

CRRNCH

"ARRGH!"

Reality had puckered, Shirou clutching his ethereal head as the sudden shifting seemed to slow, his consciousness in a grand bathhouse, a toned man in his late twenties naked and reclining, seemingly unaware of his displaced visitor, nor of the magics dispersing in the water.

Shirou looked around, trying to gain some sort of bearings, feeling the pressure mounting, trying not to scream. To the side was a set of roman silks, a large sword fashioned like the bow of a fiddle, said fiddle the sheathe, though the more Avalon's healing sparks shot out it seemed to be fading into the bath's steam.

"Hmm?"

The naked bather was suddenly shifting about, his toned body shrinking, low lusty moans beginning to rise. His patchy neckbeard was sliding off with sweat, lips swollen with arousal as the brown in his hair bleached blonde. It was saying something that this was the oddest thing Shirou had seen yet today, but it was true, especially as the changing man's form became familiar.

"Aaaaah~!"

Their blonde hair flared into upthrusted bangs, his muscles flattened to a toned, slender core, every inch of lost height seemingly bulging out from behind erect nipples as 'he' gave a satisfied groan, the water clouding above his cock as his body bucked, loud snaps arching his back as his muscled behind bloated with sudden fat, splashing water towards a blushing Shirou who tried to look away. He had seen enough, their newly rounded eyes, slender nose, the boyish yet feminine appeal of his smirking face. That was Saber wasn't it? But why would she be a ma-

"YEEEEEEEEESSS~! AHH AHH AH!"

There was a gurgling pop and the sound of bubbles as the newly christened woman leaned back, her thighs spread wide as Shirou blushed from his quick peek, seeing all the goods as she began to rise and dry herself off.

"S-Sabe-RRRGH!"

For a second she turned, trying to find the source of the voice.

"Who's there? Who dares spy on the great Ne-"

CRRNCH

There were multiple shocks at once, another reality crunch, Shirou stumbling as he went from extreme heat to extreme cool, snow falling as he shivered all over, the pressure really ratcheting up, his consciousness like a rubber band getting ready to spring away. It was hard to focus like this, leaving him only faintly aware of the swordsman practicing his swings nearby. Even if Shirou were to yell, nothing would break through his absolute concentration, each swing refining his skill through repetition, like the blade he was wielding. Like before, Avalon was spreading healing where it wasn't needed, each swing tearing muscle fiber, the swordsman cooing as each slice melted muscle, the usual healing of training replace by magic, their brow crinkling as it smoothened, no stubble on their sword shaved cheeks, but the added roundness to them grew obvious as his jaw tightened.

"HFF! HFF! HFF!"

It truly was dedication to the blade that kept him unfazed as his grip shrank, the sword shifting neatly as if it always fit smaller hands, his waist quivering as curves carved into the muscle, round hills jiggling with every concentrated strike. Shirou tried to give out a warning, but all that came out was a strangled whine, leaving him helpless as the world began to brighten once more, reality beckoning to him. It wasn't like there was much left to save, the samurai's robes shearing up to 'his' hips, 'his' breathy gasps not losing any of their edge despite the rise in pitch, 'his' hips swiveling nicely as 'his' plump thighs jiggled in the snow. Nothing could distract 'him', not the cold on 'his' exposed skin, the stroking of 'his' pert nipples nor the sudden discharge of cum, the last of her 10,000 swings leaving her unusually satisfied, her crotch buzzing as her now short sword fully sheathed itself with a quiet dribble. That was the last Shirou saw before one final crunch sent him back into his body, his world returned to him and with it, searing, blistering pain.

"Uugh..."

Shirou was back, no longer flinging between realities, taking a second to fully lock back into his body, relieved to be back. That comfort didn't last long, the pain linked back as well, every vein burning as his magical circuits felt filled with magma, his body burning. They felt like hot worms splitting through his muscle, his body cloaked in sweat, his summoned servant looking worried at him. She didn't know how to react, thoughts of Irisveil and her helplessness then coming to mind as she struggled on what she could do to help. He definitely needed help, now screaming as steam visibly floated out his pores.

Shirou stumbled to his knees, his outer layers of skin bubbling, hair forced out by leaking mana, the top few layers of skin peeling away as the heat ever so slowly began to fade. He felt something leeching from his body, a slight hiss to the fading throbs as his labored screams lessened in intensity. His body was completely smooth, hairless below his brows, the scarlet of his hair mixing with sweat, the color fading in streaks down his brow. That magma was slowing, hardening, his body shaking as pressure lightly tensed the contours of his muscle, the pain now just a discomforting heat, patches of blonde spreading up through the roots. Avalon was doing its best to fix him, his Trace having done its work, his body's composition partially made up of the Grail's energy, the discomfort now a pleasant, pulsing heat.

"Are you okay Shirou?"

She was half worried he would collapse and die any second, the violent mana vortex of his body something she could scarcely imagine a human could endure. His breathing was still ragged, but he struggled up, trying to relieve her.

"Don't worry Artoria, I think the worst of it is pa-ahhhst..."

There were a few strange things she could comment on, from his moan to the nearly fully blonded mane, but above all she had to ask.

"Shirou, how do you know my name?"

A block away, Rin was standing in shock, unsure what she was even seeing, blushing furiously as her servant moaned lustily, his cock clearly outlined against his pants, every muscle flexed as he began to shrink.

"AAAGGH! AHH AHH NOOO!"

Archer's voice quivered between enjoyment and terror, his composed form collapsed on the ground, unable to stand as his body contracted and pulsed, each breath its own struggle as his hero's essence was corrupted. It tingled along his skin, tan coloring smearing with sweat, his fingers clenched as one by one their color paled to cream, nails looking overgrown atop shrunken fingers as the changes rolled through each joint, slimming and shrinking as they spread. His ass wriggled back and forth, some great pressure building inside as he groaned, gasping as a bony click sent his knees squeezing tighter, the seat of his pants tight as his hips spread apart.

Another click came, louder, his cries tipping towards pleasure as the force spread his stubborn hips open, the changes making his prostate buzz as it was teased by the pressure, lightly throbbing as it was played with like a stress ball, each scrunch forcing him to moan as his hips struggled against the seams of their container. There was a terrible rip as he finally squealed, threads tearing apart, his knees knocking together acutely as his paling thighs grew exposed, mere threads keeping the legs attached to what were almost skimpy cutoffs, a bony girth added to his rear that he groaned under. It stung at the edges, hip bones poking at his flesh, soothed by the tingling changes that scoured his flesh of its tan patch by patch, each new one gleaming like marble. There had to be something he could do, but the pleasure buzzed in his head, slowing his thoughts as if he were drunk, his hard shaft peeking out as he felt something dig into his brain. He squealed, feeling a muscle unclench, cum dripping loosely as magic turned to fat, beginning a pleasurable thickening of his ass.

Shirou felt similarly dizzy, odd flickers of memories popping into his head, his left hand twitching as his command seals felt hot. How did he know her name? There was something nice about the way it fit on his lips, filled his thoughts. He couldn't help it, moaning out, "Ah ahhhrtoriaa..." Oh that felt good. Distractingly, enticingly good, Shirou ignorant of the ways his blonde hair was beginning to braid itself in the back, the bangs and side tickling his cheeks as he moaned the name out again, pursing his lips as they plumped from its majesty.

"Ahhh~rtoria!"

It felt like a magic word, the intense heat in his veins fizzling, melting into his body as impossible power surged into his every muscle. The mana was caressing his internals, warming them to a malleable mush as slivers dug into his outlined muscles, their shape and form hardening as he could feel his body growing stronger, his magic circuits exponentially increased as that blissful empowerment surged over every fold of his body. It was pure bliss, but the strength wasn't fully distributed, edges of his body feeling awkward and bulky, not needed for the new him that was emerging. He went to moan out Artoria's name a third time, hoping it would fix it somehow, giggling in rising tones only for a flustered Saber to yell out, "Sh-Shirou what are you doing?!"

"Huh?"

He looked down, seeing his jeans oddly loose, his left hand rubbing his shaft. It just felt too good, almost like a need, the motion so obvious he hadn't even realized he was masturbating in front of her. And then there was the hand, a hand that clearly wasn't his, slender and strong, the back of his palm huddled in his sleeve.

"What... ArtoriaaAAAA~!"

He hadn't meant to say it again, his worry quickly overcome by bliss as his chin warbled at the word, eyes delirious as they widened to emeralds, his nose shrinking as cheeks popped, a familiar voice moaning out as a stray cowlick popped up, his face fully Saberized.

"NOOOOOoooo~!"

It was strange, Archer's desire to be erased a long time goal, and yet now here he was facing it, trying to resist the inevitable. His hair flared up and out, the locks flaring out like the mane of a lion, turning equally as golden as he tried to hold onto his identity. It was terribly hard to focus when his body was intent on lighting up with such pleasure, his moans creaking upwards as the thin strings holding his pant legs were stretched. It made a sound like bubbles popping to the surface, his ass feeling like it was being internally groped and massaged as the bony width gained a curvy thickness to it. He could feel his thighs straining as they thickened, more seams bursting as the gap between them shrank to nothing, his cock spasming as it pointed upwards, his balls squeezed tight before a sudden muscular clench had him bucking and cumming, sweat pooling over every inch of him.

"A-Archer?! Why are you making those noises? Is this an enemy attack?"

He looked at her odd, wondering why she had called him Archer when he was clearly a Saber class-

"NNGH!"

RIIIP

His jeans were now cutoff shorts, the bulging muscles of his thighs too thick to contain, his calves trembling as they slimmed and curved, his feet scrunching as they slipped out of their shoes. It felt so good just to squeeze and wriggle his new legs, flexing the dainty shapes of his new toes while mana and masculinity both dribbled out from a quivering cock. Emerald was infecting his eyes, each thigh swipe making his lashes grow, his brows thinning, such warm, convincing pleasure making his tense features slacken as specks of white dotted his features. He needed to go out on his own terms, to fight this strange corruption, to get revenge on his stupid mother for- Huh? No what mother besides the queen of- There was a hard gasp as his thighs clapped, a crease suddenly stabbing up as his cum began to thin, his voice cracking as his memories shook at the sensation of penetration.

"Sh-Shirou! Your face! Your body! I don't know how this is possible but you're becoming..."

She didn't need to finish it, Ashirou feeling it in his body, swallowing as the bothersome lump in his throat melted as he moaned out, "A heeerooo~!"

Artoria wasn't sure how to respond to that, her master's smile rising, a clear moan echoing as his shoulder blades were honed down to fine, rounded frames. He knew he should be more... well anything about this news, but it all seemed to pale to the tendrils of strength caressing his waist, each muscle prickling as that useless feeling drew itself in. God he could feel the betterment happening, the blue fading from his shirt, his jacket slipping off his shrinking frame as each inch of lost height became something far more useful and tactile. Abs as hard as steel as invisible as Excalibur, hidden under a smooth layer of fat, his other hand shrinking with each poke.

His desires weren't fading as much as being swept in a new ocean of wants, his wish to be a legendary hero of justice forming with every squeeze of his waist, his sides siphoning the unneeded flesh upwards now, his toned core already perfect, a damp spot growing as he could feel the mana and strength wriggling up, suddenly bursting as they surged under his nipples. Arshirou wasn't prepared for the sudden amplification of it all, power, pleasure, especially the pleasure. The magic circuits seemed bunched in his nipples, instantly heating them to a light pink, swelling with fat and muscle and mana as the small stain became a puddle, his cock not even tensed as he let it flow, feeling with each messy spurt that something better was rushing in to take its place. Soon his former t-shirt had turned dressier, a slip on, its blue collar detached as a blue ribbon tying it together over full breasts, his nipples hugged by a bra. Out of curiosity he squeezed one, moaning as the hot stab of magic circuits responded by spilling into his leaking cock.

Archer's face was screwed up, its severe lines softening, a girlish cut to it spreading as he wriggled, moaning as the crease in his balls dove deeper, his own sac fingering out a space to cram inside. His balls struggled, flattening as his clenched jaw popped, rounding down, pursed lips swollen as his face gained a familiar look to it. Over and over he tried to remember his purpose, but he had already been weathered away by endless justice. What chance did he have against such relentless force, such blissful provenance? And the sooner he gave in the sooner he could focus on being King. Wait King? But he was turning into a-

"HYAAAAAAA~!"

The changes didn't like that thought, the digging scrotum suddenly stabbing deep, his innards quaking as he felt his balls strain before popping, a girlishly gruff moan accompanying the sudden melting of his balls, drool pooling on the ground as his body quivered, the word repeating angrily in his mind now, battering into him like he was a piece of iron on an anvil, the word heated, angry, screaming as it rattled his brains and filled the gaps.

KING

His hands clenched, arms slimming, pounded by the word, no less strong as they turned soft and womanly.

KING

The word slammed across his shoulders, each one breaking, crunching, his frame heaving as each repetition hammered it in to a diminuitive size.

KING

It slammed into his vertebrae, each one its own bizarre taste of heaven, his spine snapping inch by inch as whatever spare height could not be repurposed came from his aching, boiling cock.

KING KING KIIIIIIIIING!!!

His sides crumpled like tin, his muscles condensing, his navel slendering as the muscles gained an alluring appeal. He was still ripped, but there was a subtle softness over the diamond cut abs, his nipples rubbed sore from his shaking, the shrinking wet cut of his shirt pulling tighter as he begged for mercy, only to feel the brunt of the changes slam upwards, straight into his leaking cock.

Arshira was panting like an animal in heat, sweat pooling all over as he tugged at his clothing, overly sensitive to even the most minor of brushes. His nipples were electric, large shocks of pleasure making him buck as even the squeeze of his arms around his breasts was unbearable. It was because of the circuits, his whole body on edge, a complex weave of them stabbing and filling his cock, tattooing his shaft in a web that grew hotter and hotter. It didn't take long for him to tear apart his drenched shirt, his pants slipping as they were halfway through their transfiguration into a skirt, socks and shoes flinging off shrinking feet, flexed in unbearable ecstasy as the gush of cum slowed to a trickle, then to nothing at all. His body had no use for it, the green lines of circuits glowing over his groin, the left half glowing brighter. For a second he was reminded of when Merlin had cast a spell on her, the heat and maddening ecstasy as-

SSCHLLP

POP

"HYAAAAAAAAAA~!"

Thinning cum blasted from his burning cock, the left ball smashed inside, pounding into his half formed gap, wrenching his left hip apart as estrogen and magic poured into the leaking hole. Sumptuous fat poured into his left ass cheek, filled his thigh to near bursting as he felt the lump squeeze down a channel, heat and bliss burning through as the circuits tugged at his cock, jerking it as the whole shaft tilted to the left like a tower on uneven ground, even his half formed pussy seemingly brimming with muscle as the ridges sucked and stroked his leaking shaft. Arshoria could feel something massive about to burst, his toned body struggling, giving a lusty, strangled moan as the remainder of his sword's hilt struggled its way inside. He hugged himself, shrieking and grunting as the final jerks assaulted it, knowing from Artoria's memories of gender magic that this was going to be an intense experience.

Emorga was screaming, his class no longer certain in his mind, his cock hammered by the tomboyish voice screaming to become a king, the force of it sprawling him to the ground as the rest of his shirt tore away, leaving a skimpy crop top to hug his tender chest, his body rocking forwards once more as another hit tapped his cock inside another inch. Mordra rolled on the ground, shrieking as nothing could protect his cock from being driven inwards, hot shocks making his nipples bloat, scraping against the asphalt. He stumbled to his knees, cumming as small slivers of fat continued to push his chest out, pushing and... He looked down, expecting more to come, not exactly thrilled by the breasts but kind of annoyed at how tiny they were compared to Artoria's. Not that he wanted them bigger, but this was losing to that king, Mordrad giving them an annoyed poke, hoping to spur some growth only to regret it as the tweak to his nipples made his cock suddenly spill, the separated strikes now a constant tapping as his cock was hammered in.

"AHHHH~ F-FUUUUCK NOOOOOH~ OHH SHIIIIT!"

His hands scrabbled for it, the last remnants of his former self struggling to grab it, slapping at his thick thighs as the tip of it slid out of sight into the edge of his cutoffs. He could feel the bone of his sword, relentlessly driving into his guts, his stupid, thickset thighs blocking his clumsy fingers, now barely two inches outside the hungry slit, the plunging organ ready to stab into his throbbing womb.

"STAAAHP! S-STTAAAH AHHH~! HHNNGH!"

Our of desperation he swung up his leg, trying to get at his cock, to squeeze the tip and pull it out, but the sudden swing of it caused his new muscles to twitch and retract, the last dredges of cock popping inside as Mordred screamed, feeling it fuck him as it inverted inside, the new Saber class struggling to hold his moans back as he came.

You'd think Artoria would be more disturbed by the sight of her master cumming and turning into her, but then again this was hardly the first time such a sight had graced her eyes. Even now she was blushing at the thought of the nights she had spent, conceiving Mordred, the uncouth sounds Shirou made not all that different from how she felt when Merlin's magic had scraped her most secretive of spots and tugged out a cock. She did however not want things to drag on too long, one fight already finished earlier and she could hardly imagine an easier target right now than the moaning mess of a twin cumming before her. Sighing with reservation she moved towards her master, deciding to put her skilled hands to work on a most tender blade, her sword handling skills well known, especially by her loyal knights of the round table.

Arshoria was drooling, his mind as fractured now as it was hurtling through the grail, his remaining ball taking forever to pop, the thigh and ass bloating as it filled him with mind numbing bliss, far greater than anything he felt as a man. Though it wasn't the last thing he felt as one, the cool touch of Saber's palm on his cock nearly making him pass out, her calm strokes pushing as she worked his cock inside. The sheath of Avalon was waiting to be filled, Shirou's sword a poor substitute for Excalibur, but Arthoria couldn't think. He was fucking himself, or was she fucking herself? The difference was blurring, Saber's skilled pumping driving length after length of cock sliding up ridged walls, unfolding her cock inside as slimy spurts of cum gushed till they ran clear, her thumb and index squeezing his tip tighter until it sealed, cum bubbling around the edges of his slit as she circled his clit. It only took a solid press for the last of Shirou to be fucked away, the new Artoria screeching a high note of utter bliss as her former cock popped inside, the freshly fucked monarch enjoying the pleasures of her new flesh as the changes finished.

Saber stared at her twin, watching her chest heave as she came down from the orgasm. It wasn't an entirely unfavorable outcome, Shirou's recklessness granting him the body of a hero and with it, a magic capacity that was already supplying Saber with far better mana than before. Her twin looked up, more amused than worried, her mind still a bit caught in the gutter from the sensations.

"Mmm~ well that was certainly an unexpected pleasure. We haven't felt like that since-"

"DAAAD!"

They both swung around, more shocked by hearing their daughter's voice than the entire transformation.

"Mordred?"

"Daughter?"

He ran with a shellshocked Rin in tow, the latter blushing furiously and mumbling under her breath while Mordred gave a dirty look at the former Shirou.

"It's your son da- Wait why are there two of you? And why is one of you half naked?"

Rin was tottering back and forth, looking around for something that made sense.

"What's happening? I don't understand. Where's Shirou, I should talk with-"

Artoria raised her hand sheepishly, Rin's stare growing deader as she let that sink in.

"Er, that'd be the former me I believe."

She was quickly slipping into a spare dress hanging from a box in the nearby shed's loft. Rin just went to a corner to grapple with all of that, rocking in the corner as Mordred shifted uncomfortably trying to comfort her.

"You wanted a Saber class initially so hey maybe this isn't so-"

She shut the door to the shed.

"...I think she needs a moment. She saw the whole, whatever this was. But ha! Even if I came back weirdly, I can finally settle the score with you! I can finally-"

"Ah I didn't know you wanted to be closer to your mother. I too have thought long and hard in the grail about our last talk."

Mordred was shocked when he was hugged, trying to wriggle out of his mom's grip.

"That was a fight! Not a talk!"

"Given our usual talks there's little difference. Come now, you can't deny you are my dau- my son."

"L-Let go of me I'm not-"

The other Saber frowned.

"Have you been eating properly son? You look so thin. And I know one of us was in a bikini but that's no way to-"

"Aww you're so cute. Here let me help you rela-"

"And your training you better not have-"

Mordred had fought many battles in his life, but never was there one as hopeless as getting his dads to shut up as they ushered him inside, Mordred reluctantly hanging his head as they fussed over him. It seemed he had lost his first battle of the Grail War.
