An Overwhelming Duel and the Busty Class Rep's First Climax
When Go Yushin pushed open the door of the ancient training hall and stepped out of its severed pocket of spacetime, the frozen time and muffled noise of Arhen Magic Academy came flooding back all at once, and the world began to move again.
The class that followed the magic circle practical was live combat magic dueling, held on the academy's vast central arena.
There could have been no more perfect stage to test the power of the S-rank proprietary magic system he had just completed in the training hall — Reversion — on a real battlefield.
Yushin rolled his shoulders and cracked his neck lightly as he walked out into the very center of the sandy arena.
In the eyes of the dozens of noble students seated in the surrounding stands, curiosity, envy, and jealousy were tangled together as they stared at the special transfer student who had stunned the morning's mana measurement with an A-rank result.
"Hey, transfer student. I don't know what kind of trick you pulled on the mana crystal, but let's see if that bluster holds up in a real fight. Come at me. Today I'm going to snap that arrogant nose of yours flat."
Strutting out from behind the stands with a snickering entourage in tow, a blond male student draped in a top-quality magic coat embroidered with lavish silver designs approached with a supercilious smile.
It was Andrew — scion of one of the academy's most prestigious noble houses, and a known prodigy of offensive magic.
Yushin let out a short, derisive laugh and met Andrew's haughty face head-on.
"Perfect timing. I was just looking for a living sandbag to test the technique I learned a minute ago. You walking right up to me on your own two feet — I appreciate it."
"Wh-what did you say?! You lowborn piece of—!"
Andrew's face flushed red and mottled in an instant.
Just then, class representative Erika came hurrying up to the fence at the edge of the arena, worry written across her face as she caught her breath.
Her overflowing G-cup breasts trembled inside her uniform blouse.
"Yushin-ssi... please be careful! Andrew's personality and conduct are awful, but when it comes to fire magic's raw power and casting speed, he's first-rate — upper-rank battle mage level!"
Yushin gave Erika a relaxed wink and waved a hand.
"Don't worry, class rep. It'll be over in three seconds."
Instructor Shuka, presiding over the duel, stepped between the two and raised her hand with firm authority.
"Both combatants, are you ready?"
"Is there even such a thing as ready, Instructor? It'll end one-sidedly the moment we start."
Yushin shrugged and taunted him, and Andrew ground his teeth as he gripped his magic staff.
"I'll make you regret that, you insolent bastard...!"
"If things turn dangerous, the duel will be halted immediately. Begin!"
The instant Shuka's signal fell, the air pressure across the entire arena seared hot in the space of a breath.
Without a flicker of hesitation, Andrew slammed his staff down and completed a massive triple-layered fire magic circle at a terrifying speed of less than five seconds.
"Burn to ashes! Inferno!"
⟨ Inferno ⟩
FWOOOOOOM!
A colossal pillar of fire, dozens of meters across and evocative of hell's infernal flames, melted the arena floor as it surged toward Yushin with terrifying momentum.
Even as the students' screams and cheers mingled into a single roar, Yushin — determined to demonstrate the overwhelming gulf between them — kept both hands stuffed in his pockets and did not move a single step.
And in the very instant the flames closed to within a few dozen centimeters of his face—
Yushin drew one finger just barely out of his pocket and flicked it toward the empty air.
"Silence."
Silence — Absolute Mana Severance
Ssssshhh.
The moment the word was spoken, the colossal pillar of fire that had been tearing through the air came to a dead stop in midair — like a single frame of a film frozen in time.
The sound, the explosion, even the heat vanished completely.
Every link in the chain of mana circulating through Andrew's magic circle had been forcibly severed before Yushin's absolute silence, evaporating without a trace.
"...N-no incantation?! And my Inferno... how the hell did the spell just disappear?!"
Andrew's eyes bulged with sheer shock.
"You fired it, so take it back yourself."
As Yushin gave his wrist a light shake, the pillar of Inferno flame Andrew had just deployed rotated in the exact opposite direction and came crashing down on its own caster.
Reversion's applied technique — Revert.
The spell's vector and command structure, reversed upon its caster.
FWOOOOOOM!
"GRAAAAHH—!"
With a scream, Andrew's body was launched a dozen meters into the air and slammed into the arena wall, where he promptly lost consciousness.
In the blink of an eye, the entire arena was plunged into a frozen, suffocating silence.
Instructor Shuka swallowed hard and shouted in a daze.
"Th-that's enough! Winner: Go Yushin!"
"WHOOOOAA...!"
A thunderous eruption of awe burst from the stands.
Erika clasped her hands together over her chest, tears welling in her eyes as she gazed at Yushin with an expression lost in rapture.
"Yushin-ssi... you're truly incredible...!"
But in a corner of the arena, beneath the shade of a tree, one man watched the scene while weeping tears of blood.
Erika's country-bumpkin childhood friend — Ryuk.
"Damn it... Erika is making that bitch face at a guy like him...! Erika is mine... she promised she'd love me forever...!"
Ryuk raked his nails against the bricks until they split and bled, a gloomy killing intent smoldering off him like smoke.
"If you take Erika away from me... I'll kill you... I'll kill you for sure...!"
Yushin, gifted with the hearing of a superhuman, caught every syllable of Ryuk's sinister curse as clearly as a bell — and he simply curled the corner of his mouth upward, sneering inwardly.
The precious childhood friend you cherish so much? Tonight, I'm going to enjoy devouring her virginity whole.
That night.
Inside the finest inn at the school's outskirts, where moonlight filtered in softly.
Yushin had spread an S-rank Silence barrier thickly across the door and every window, sealing off all outside gazes and mana detection.
Out in the darkness beyond the inn, Ryuk — who had been grinding his teeth and straining to peer through the window — found only pitch-black void where the magic sealed everything away, and he wept tears of blood as he gnawed at his fingernails.
"Goddamn it... I can't see a damn thing inside... Erika, please don't cheat on me...!"
But inside the room, beyond the barrier, thick and feverish cries of passion filled the air, paying Ryuk's wailing no mind whatsoever.
"Ahnn...! Haaahnn, Yushin-nim... hold me harder, please...!"
On the bed, Erika — who had undone every button of her thin uniform shirt with her own hands — was rubbing her body shamelessly against Yushin's firm chest, her impossibly huge G-cup breasts swaying and jiggling with every movement.
Her pink nipples stood rigidly erect atop her milky-white, supple mounds, and her narrow panties were already soaked through with translucent virgin nectar.
"Yushin-nim... I-it's my first time, but... if it's yours, I don't mind tearing... please, put it in...!"
In response to Erika's blind pleading, the massive cock that surged up from Yushin's waistband reared hard and veiny, burrowing between her narrow thighs.
Yushin spread Erika's legs wide and bent them back until her knees pressed nearly to her chest, taking her in the most extreme of mating presses.
POOCH!
"HYAAAAAAHK...!"
Bright-red virgin blood seeped across the pure-white bed sheets as Yushin's forearm-thick cock plunged in a single stroke all the way to the tight, dense mouth of her womb — a passage that had never once been opened in her entire life.
The soft inner folds of her walls clamped down around his massive shaft as if to tear it apart, spasming wildly.

THWAP! PAM, PAM, PAM!
"Ohgoh...! Ohhk, ohk...! Yushin-nim's cock, it's so big and thiiiick...!"
Erika's eyes rolled back until only the whites showed, silver drool trailing from the corner of her mouth as she screamed in ecstasy.
Yushin drove his hips down from above, mercilessly putting his full weight behind every thrust.
SLAP—!
"Moan louder and squeeze tighter, class rep!"
When Yushin's palm came down hard on her plump, milky-white ass, Erika's body arched up off the bed like a fish flipping out of water, and she milked his cock with a crushing, killer grip.
"UUHOOOONK—! NGOHOOONK—! It feels good, so good, Masteeer...!"
The supreme pleasure of her womb being ground to its very depths shattered her reason entirely — and with her childhood friend completely erased from her mind, Erika thrust her hips back like Yushin's personal bitch in heat.
He couldn't hold back any longer. Yushin gripped her thighs hard enough to bruise and buried his glans firmly against the deepest recess of her womb.
BRRRRRUUUUK! FYUUUUUT!
"HIIIIIIK...!"
Yushin's hot, thick seed erupted without restraint, pouring deep into Erika's womb like a waterfall.
Erika shuddered from her hips, spraying her nectar across the bed like a bursting fountain, before collapsing onto the mattress, utterly spent.
But Yushin did not stop.
He lifted Erika's limp, panting body and settled her astride his hips, switching into a lifted-carry position.
PUSK!
"Ahhn...! It's, it's going in againnn...!"
Yushin swallowed her plump lips in a rough, deep kiss, and Erika greedily sucked and drank at his tongue while opening her womb wide to him once more.
BBRRRRRT!
When the second great storm of seed filled her until her belly bulged and her womb brimmed to overflowing, Erika let her tongue loll free and slipped into a deep sleep, fainting into Yushin's arms.
Outside the room, oblivious to everything, the shadow of her childhood friend Ryuk paced back and forth weeping tears of blood through the long night — while within, the only sound was the sweet, contented breathing of the busty class rep Erika, flushed with happiness as she nestled Yushin's seed in her womb.
