I Took A Succubus's First Time

Natsuya was blocking every attack Aria threw at him, but each time their blades collided, the shock rattled straight through his bones, burning through his muscles and making it feel like his arm would just snap the hell off.

The clangs echoed sharp and metallic with each strike ringing in his ears louder than the last, drowning out the chaos of the battlefield around them.

Every dodge he made felt like it took every ounce of his mind and reflexes, but even then, it wasn't enough. Aria moved like something out of a nightmare with her every sidestep, every backstep he took, she was already there, like she'd read his mind before he even thought of moving.

Clang! Crash! Wham!

Her sword cut through the air with a force that made it hum, the wind around each swing slamming into him like a physical blow. His breath caught in his throat, sweat running down his forehead and stinging his eyes.

This was fucking ridiculous. How could someone be this fucking powerful?!

He was being forced back, step by step, the ground cracking under his boots from the weight of their clash. His chest burned with every ragged breath, heart pounding like a war drum against his ribs. He could taste iron in his mouth where he'd bitten the inside of his cheek, trying not to lose focus.

He'd chosen the wrong goddamn match-up.

Natsuya was never meant for this shit. He wasn't some frontliner thirsting for blood and glory. He was the quiet one behind the scenes, the one who bent space itself with his portals to control the flow of battle and not get caught up in the raw, bone-breaking violence of it.

He was the strategist. The thinker.

'This is why I warned Souichiro-sama… told him this shit could go sideways… but no, he just had to act like he fucking knew everything…' Natsuya's mind screamed between blows. 'If he'd listened, maybe none of this would be happening right now… fuck…'

But knowing Souichiro, it made sense. That smug, arrogant confidence was carved into every part of who he was. Most times, it worked. That was because he had power. Real power, and it was the kind that made people shut up and follow. But arrogance like that? One day it would snap back and tear everything apart.

'If only he'd listened… just once… this could have been stopped before it ever got this far…'

A sharp clang exploded against his sword, the vibration running up his arm so hard it made his shoulder feel like it had been ripped out of its socket. He clenched his jaw, a hiss escaping between his teeth as Aria pressed harder, her strength almost inhuman.

He knew he could come up with something. Maybe a plan, a feint, or anything similar. But if only he had space to think. But thanks to Souichiro's stubborn refusal to take those "defects" seriously, he had nothing. They were left fighting monsters.

And then there was the Child of Anti-Prophecy… the root of all this chaos. 'He really did bring monsters to life around him… these women, they're terrifying because of him…' Natsuya thought, sweat dripping from his chin. 'And what the actual fuck is up with them having an angel helping them revive him? That thing is a goddamn walking disaster waiting to happen… and is too fucking dangerous to leave alive…'

A fresh shock of pain shot up his arm as Aria's blade smashed into his again with the force rattling his teeth and the impact so heavy it vibrated his bones. He almost dropped his sword right there and he barely caught it before it slipped from his sweaty fingers.

Desperate, he pivoted, flung himself sideways, and opened a portal mid-stride, a swirling oval of distorted air he dove into like a drowning man grabbing a rope. He reappeared a heartbeat later with a fresh ground under his boots, but his relief turned to cold dread immediately.

Because Aria was already there.

Standing in front of him like a phantom with a blade, eyes locked on him, the edge of her sword flashing up for his throat.

'Can she give me a fucking break for once?!'

His mind reeled as he threw his sword up, the impact sending another bone-deep shock through his arms. Sparks danced between their blades, metal on metal, the shriek of it echoing like a scream through the scorched air.

There was no pause and no gap to breathe. There was also no room for him to think. Her strikes came relentless like a storm with no end with each swing fast enough to blur and sharp enough to split him in half if he slipped even once.

Natsuya sucked in a ragged breath, eyes darting for any escape or any plan or any trick left up his sleeve. But deep down, he knew. His mind was a vault of tactics and traps, but none of it mattered when the enemy was a blade pressed against your neck before you even finished the thought.

He was outmatched. Very much so.

Natsuya's breath tore ragged from his lungs, chest heaving so hard it felt like his ribs might crack open. No… fuck this. I'm not dying here. His mind burned with his gears turning faster than his pulse.

He grit his teeth, shoved the pain aside, and hurled himself backwards through another swirling portal, the air warping around him with a low, hungry hum. He landed hard on cracked stone, boots skidding, barely regaining balance before Aria blurred into view again, sword already cutting through the air.

He slashed his own blade out defensively, just enough to catch the edge of hers with the clang ringing in his ears so loud it drowned out even his heartbeat. Sparks rained between them, tiny pinpricks of heat biting at his face. The shock jarred his shoulders near out of socket, but he forced himself to move, shifting his stance, pivoting around her, trying to get any kind of angle.

Every time he made space, she was there again, merciless, like the Reaper itself draped in flesh.

Natsuya bit the inside of his cheek hard enough to taste copper, eyes narrowing. She's faster… stronger… but I've still got my portals. I just need… one opening.

His hand twisted mid-swing, and he flung open two new portals behind him with one high and one low, then he ducked through the lower one in a blur. He shot out from above, dropping down on Aria's flank, blade poised to slice into her shoulder.

But steel met steel as she'd turned almost lazily, sword flashing up to block his strike with her gaze never even flinching. The impact jarred his wrist, a spike of pain lancing up to his elbow, but he forced himself to follow through, twisting his blade in a desperate attempt to shove hers aside.

Aria barely budged. The shockwave of their clash made the broken ground quake, dust blooming around them like smoke.

Natsuya staggered back, chest pounding so loud he could barely hear over it. Sweat dripped into his eyes, stinging, but he didn't wipe it away. Again… fucking again!

He snapped another portal open, this time wide enough to step fully through. He dived inside, reappeared behind her, swinging his blade low, aiming for the tendons behind her knee.

He was doing anything to slow her down.

She spun, metal flashing, and caught his blade against the flat of hers, the clash exploding in sparks so bright they burned spots into his vision.

His teeth clenched, jaw aching, but he pushed with his muscles screaming and his sword pressing hard against hers, every fiber of him straining to break through her guard.

Aria didn't even look rattled. Her eyes locked on him, cold and focused, as if measuring the exact moment he'd slip.

Fuck…! His mind raced. She's reading every move. Predicting every portal. How the hell—

He tried to fake her out as he threw open another portal at his side, feinted toward it like he'd jump through, then pivoted to swing from the opposite side.

Aria didn't fall for it. She stepped in, closing distance before his swing could even build momentum, blade coming up under his guard with frightening precision.

He barely twisted aside, the edge of her sword slicing across his shoulder, searing hot pain exploding down his arm. Blood sprayed, a dark arc across the ground.

Natsuya hissed, breath shuddering, sweat and blood mixing, dripping from his fingertips. The burn in his muscles was near agony with his arms trembling under the weight of his own blade.

No… no, not yet. I'm not done…!

He spat out the blood pooling in his mouth, eyes wild, and roared. It was a raw, ragged sound torn from deep inside. He slammed his foot into the ground, cracking the stone under his heel, and poured everything he had left into a last flurry of portals, and then, one after another, swirling around Aria in a chaotic spiral.

He lunged through them, striking from above, below, left, right with his blade whistling through the air, metal singing with each desperate slash. The rush of wind from his own movement battered his face, his heart hammering so hard it hurt.

But every strike met hers. The clash of steel rang out again and again. Sparks rained around them like embers with each impact jarring his bones until his grip felt ready to break.

His breath tore out in ragged gasps, vision narrowing, edges darkening with exhaustion. But he kept going because stopping meant dying.

Come on… come the fuck on…!

For a moment, it looked like he'd created space, his sword scraping across her guard, biting into her side.

It was a shallow cut, but it drew blood.

Aria's eyes flickered, her stance shifting slightly.

Now!

He threw himself forward for the finishing blow...

...only for Aria to meet him head-on, steel flashing with blinding speed, a single, perfect arc that smashed into his blade so hard it rattled the marrow in his bones.

The sword flew from his grasp.

'D-Damn it...!'

And then, before he even knew it, before the sword even fell into the ground, Aria had already swung her blade to his chest.
