The Arrogant Demoness is Weak to Dick (1)
Light burst from the empty air. It faded in an instant, revealing a metal gauntlet. I mounted Sesiah and soared into the sky. Carefully grasping the white gauntlet, I slipped it onto my right hand. In that moment, information about the gauntlet flooded my mind.
One of five artifacts that perfectly recreate the power of the angel Metatron from mythology.
Collect all five and wear them to become Metatron himself, wielding tremendous power.
‘Oh, handing over something like this...’ I clenched and unclenched my fist repeatedly. The finger joints moved smoothly, with no sense of weight. Immense energy pulsed within the gauntlet. Even with Erkness's Lasso, I'd been dragged around by the fake Sesiah because she overpowered me—but with this gauntlet, that would never happen again.
Demigods sure are generous. I'll put it to good use, gratefully.
"Let's go."
Wearing the gauntlet, I soared freely on Sesiah. I'd just acquired the world's finest mount—time for a test drive.
About an hour after Hero Kang Naru and Pegasus Sesiah began their battle. The spectators at the camp were going mad with frustration, clueless about the situation. All the crystal orbs broadcasting the scene had gone dark.
Sesiah's monstrous lightning strikes had obliterated every floating Myilrun orb in the sky.
"No sounds from the mountain—must be over, right?"
"It's gone quiet too. What the hell happened?"
"I'm dying of curiosity here!"
"H-Hey, look! Something white's flying in the night sky!"
"Huh? Where?"
"Where do I look?"
"The eastern sky, I said!"
"Eastern sky? Whoa! S-Sesiah!"
"Someone's riding on its back!"
"It's Kang Naru! That's Hero Kang Naru!"
"Ooooh!"
The sight of Naru riding Sesiah and circling above the camp sent the entire place into a frenzy.
"Hero Kang Naru has claimed Sesiah!"
"Waaaaah!"
"Kang Naru! Kang Naru!"
"Incredible!"
As cheers erupted from every direction, Grand Mage Glenn wore a regretful expression, thinking of his wife.
"Sorry, dear... I couldn't do it."
Nearby, Dwarf warrior Hokan hurled his horned helmet to the ground.
"Damn it all! We're heading back!"
"Yes, sir!"
The centaur Ramo was in awe.
"A pure heart moves the heavens..."
Standing beside him, deputy commander Logana smiled warmly and nodded.
His cock was unusually impressive for a human... Turns out it matches his power.
Naru's companions had all rushed outside, grinning ear to ear in delight.
"Professor, give me a ride too!"
"Me too!"
"Naru! If you don't take me first, no more Tempest from now on!"
Everyone in the camp lingered in place for a long while, cheering endlessly. Naru responded to their celebration from the sky before descending, letting them admire Sesiah up close, and sharing the joyful moment.
It was past midnight. The camp lay silent, but I alone remained awake. Sleep tugged at me, yet there was unfinished business before bed—something I'd put off amid the chaos.
I stepped out of my tent and entered Jenia's. Soft candlelight illuminated the interior. Jenia, Deborah, and Hanna waited there. And hanging from ropes tied to a ceiling hook, her arms bound above her head in the nude, stood a demon woman.

"……"
I walked in silently, fixing my gaze on the demon woman's body.

Two horns sprouting from her head. Indigo skin. A sleek, curvaceous figure. Plump breasts perfect for milking. Firm, wide hips...
"Where you lookin' at, you bastard?"
The foul-mouthed demon woman cackled.
I'd come to deal with her. Lifting my eyes, I met her gaze.
"Padmera, right? Buzdra Academy graduate."
"You even dug into my background?"
"Heard it when you infiltrated our academy before. Why target the students? Kidnapping them for what?"
"To make monsters. Monsters."
She burst into roaring laughter. I furrowed my brow slightly.
Ears hurt. I hated noisy disturbances late at night.
"Oppa."
Jenia approached.
"If we leave her like this, she might try escaping while we sleep. Better drain her energy first."
"Got a good way?"
She held out her palm. A rubbery thing like a condom appeared.
"Hey, that's..."
"It's the best option."
"No thanks. Think of something else."
"You're such a softie. Idiot."
What Jenia showed me was "Incubus Dream"—a tool dark elves used to siphon women's essence. It sucked out vitality with every orgasm, leaving them weakened. But it required slipping it on your dick and thrusting into her pussy, forcing sex.
I just didn't want to fuck a demon. Hero's pride and all.
Technically, heroes should slay demons on sight, but I'd spared Padmera for reasons. First, Jenia had captured her alive and wanted to use her—like how she'd revived Deborah and Hanna as undead minions.
And since Padmera wasn't a pure demon but a former human, I held faint hope of redeeming her. I planned to take her to a temple.
By my code, I don't kill those with human blood recklessly. Heroes are endlessly merciful to humans. Even fallen ones get a shot at salvation if there's a spark of hope. Terrifying only to demons.
The god who granted my hero powers would want me saving as many as possible over mindless slaughter.
"No desire to become human again?"
Let's see if words get through.
"I'd help with everything I've got if you do."
"Ahahaha! Why would I? You nuts?"
"Don't laugh—think seriously."
"Dumbass!"
She bared her fangs, spewing curses.
"Think I'll be scared 'cause you're acting all serious? You can't touch this body, let alone have it! I've got a powerful barrier around me! Ahahaha!"
Huh? Doesn't she know I broke her barrier?
Naive girl.
Padmera must feel safe with her barrier up, spewing nothing but nerve-grating bullshit.
"I'll devour you for sure! Once I'm fed, I'll use those students you drag around as guinea pigs for new monsters! Cruel, powerful ones to shock the world!"
"Cut the crap."
"I'm a high demon! Hero, swear loyalty and I might let it slide. Kneel, beg forgiveness! Now!"
"Shut up."
"Fuck off!"
"Keep it up and I might have to hurt you."
"Try it! Ahahaha! Your mom's a retarded bitch who fucked rats and frogs and caught the plague!"
"Abandon the darkness and submit to the gods."
"Bullshit! Shove your dick up your daddy's ass, you retard!"
Enough. Even a hero can't stomach mom insults.
"Jenia. Oppa was wrong."
Click.
I unbuckled my belt, dropped my pants, then yanked down my underwear and tossed it aside with them.
"Your way was right."
Showing her my flaccid cock, Padmera—who'd been spewing garbage—froze. Her huge eyes locked onto it.
No way...? Her face said.
That's exactly it, demon girl.
Words won't work. Time to shut her up with tools.
"Gimme the Incubus Dream."
I held out my hand. Jenia knelt before me.
"You can't put it on alone, oppa. I'll do it."
She casually gripped my cock and took it in her mouth.
"Hey...!"
"Gotta get it hard first for a good fit. Slurp."
"Ngh, still...!"
The jolt surprised me, but whatever. We'd already done it, sister and I. First time's the hardest; second's easy. Rationalizing that a blowjob's fine, I let her service me.
As long as it doesn't go in her pussy.
Protect her virginity, and she can marry safely.
"Slurp... slurp, slurp."
Jenia sucked diligently. Licking the shaft, tenderly nursing my balls.
"Hoo..."
A moan escaped unbidden. Treating her future family-head brother's cock with utmost devotion. Her hands cradled it reverently, mouth and tongue pampering it carefully, as if a single scratch would be a tragedy. Even a girlfriend or wife wouldn't handle it this delicately.
Touched by my little sister's kindness, my cock stiffened fast—rock-hard deep in her throat.
"Cough, cough!"
Jenia coughed briefly, then fitted the Incubus Dream over my cock. The rubber clung perfectly.
Basically just a condom.
"Slurp! Slurp! Slurp!"
To secure it, she sucked with renewed vigor. Once it settled snugly, she wiped her lips with the back of her hand and stood.
"Done."
"Yeah, thanks."
Jenia glanced at the floor, picked up my discarded underwear, and pressed it to her nose. Inhaling deeply, she grimaced.
"Hmmm, oppa's filthy cum stench. So nasty. I'll wash it and bring it back in the morning."
She pocketed it.
Right then, my cock—sheathed in the Incubus Dream—transformed into a black dick pulsing with dark energy.
Padmera snickered.
"Nice cock you've got. I'll give you that. But what're you gonna do with it? Can you even touch me, loser?"
Cheeky bitch.
Isle Silence
I instantly shattered the barrier she boasted about, right before her eyes.
"I broke your barrier earlier today."
"Wha...? It wasn't an Isle malfunction...?"
"Nope."
"N-No way...!?"
Fear flickered in Padmera's eyes. I grinned.
"Feeling tense now?"
With my black cock—glistening from tip to root—standing proud, I approached her slowly.
A hero fucking a demon went against professional ethics, but demon pussy... let's savor it leisurely.
