There's a Reason the Demon King Wants the Hero to Grow
"Heh heh heh..."
Inside the Demon King's Castle, Jae-hyun laughed with his head slightly bowed.
Irene, still seated on his lap in her wedding dress, asked,
"Did you go meet the ancient hero?"
She had sensed the ancient hero's descent herself, of course, and Jae-hyun had told her he was going to meet him through one of his clones. From his reaction alone, she knew at once that he had already returned from that encounter.
"Yeah. I met him."
"What kind of person was he?"
Irene knew of the stone tablets that recorded the ancient hero. She had been a merchant's daughter, not a noble, so she hadn't been present when the tablets were first discovered—but she was the one who had later trained Jae-hyun after his summoning as a hero, and so she had learned of them eventually. Naturally, she was curious what kind of being the ancient hero truly was.
"A bastard who dreams of conquering the world. And he had the gall to declare war on me, saying he'd take you and Lucretia as his wives."
"Why didn't you just rip his mouth open?"
Their wedding had only ended that day. Barely seven hours had passed, and Irene was still steeped in the joy of being a newlywed. Of course, she hadn't managed any proper sex in those nearly seven hours—she'd simply sat on his lap the whole time with his cock buried in her ass—but she was happy all the same. Hearing that some lunatic had set his sights on her was enough to sour her mood.
"Don't worry about him too much. He'll be stuck where he is for at least a week. He was only ever summoned to this world as an energy source anyway. Heh. And as for the ones who answer his call and come here... they'd better be ready for hell."
The only reason the ancient hero could be summoned into this world at all was because Jae-hyun had covered for Ferdinand and Griffith's actions—so that Yu Ji-ho's soul could be used as fuel for dimensional travel. And Jae-hyun had already prepared a punishment for the man's insolent declaration that he would steal Irene away. Yu Ji-ho had dared to announce he would violate Jae-hyun's women. That kind of overreach could not go unanswered.
Jae-hyun fully intended to rape every last one of the bitches the man summoned and turn them into soldiers of the dark army. As for the hero's family, he was more than willing to personally remodel them into the most grotesque monsters imaginable.
"Well, I'm sure you'll handle it, Jae-hyun oppa."
Irene trusted him to deal with it and put the ancient hero out of her mind. What mattered to her far more was the honeymoon she was living right now.
And what caught her eye then were the women being penetrated and pounded in mouth, pussy, and ass all at once. Among them, the delicate, pure-looking blonde beauty Rin—hardly the image one expected of a black mage—drew Irene's gaze in particular. Having retained most of the emotions from her human days, Irene had taken quite a liking to the girl. Rin's brother Ron meant nothing to her, but Rin herself she found adorable.
"Mmph! Mmmph!!!"
Taking Jae-hyun's clones' cocks front and back while sucking on another, Rin suddenly twisted her body, eyes flying wide—then squeezed them shut and shuddered hard. She had clearly just climaxed, and scarcely a moment later the clones' cocks flooded both her holes and her mouth with cum. Rin swallowed it down with practiced ease by now, and around the same time Selina, Lucien, Serphius, and Lillian were likewise filling their mouths and lower holes with Jae-hyun's seed. The cum poured down their throats; what had been dumped below packed their wombs and the depths of their rectums full.
"Mmph! Mmph!"
And the female Red Dragon—a naked beauty with crimson hair—still sat in resigned stillness, obediently rolling her hips to grind the cocks buried in both her holes while working her mouth over another, the very picture of a devoted sex slave. Dragon or not, with all her power sealed she was nothing more than a woman in a human body, and even a dragon's willpower was not enough to endure sex with the Demon King. Considering that even an incubus—a creature that could seduce a woman and corrupt her through sex in a single encounter—was ultimately just one more demon subordinate to the Demon King, it stood to reason that if Jae-hyun ever put his mind to it, he could reduce hundreds of thousands, even millions of women to creatures who could no longer even conceive of another man.
It was only that Jae-hyun, consumed by his obsession with Irene, his thoughts of revenge against the betrayers, and his family back on Earth, had almost no other emotions left—and so he simply hadn't bothered with women much.
"About ten days until the child is born."
Even as he savored sexual pleasure through his clones, Jae-hyun stroked the belly of Irene seated on his lap, far more focused on the fact that she was pregnant. He had creampied Rin, Selina, Lucien, Serphius, and Lillian, of course—and even Learis, the female Red Dragon he had tasted for the first time today—all with the intent of impregnating them. As the Demon King, he would have them carrying his children soon enough if he so wished. But Irene had been the first to conceive, and she would be the first to give birth as well.
"Ten days... a demon's pregnancy really is short."
"That's because so many of them die."
A gestation of only ten days—so wildly different from a human's—struck Irene as wondrous. Jae-hyun found nothing particularly strange about it. Without his orders as Demon King, Selina's vampires, Lucien's dark elves, and every other race would be constantly warring over territory as a matter of course—and even within the same race, challenges over rank and fights to the death were hardly rare. Lillian's succubi, at least, had relatively little appetite for battle—that drive was largely replaced by an appetite for sex—but they still got dragged into wars often enough when others picked fights with them.
Since Jae-hyun had taken the throne as Demon King, all such fighting had been forbidden outright, and everyone had simply been accumulating power. But the moment there was no Demon King, Selina, Lucien, Serphius, and Lillian—currently lined up so amicably, fucking his clones side by side—would instantly turn on each other as mortal enemies.
Demons were untrustworthy beings by nature, and it was only natural that they could not trust one another either. The reason the angels of Heaven—clearly far weaker in raw power—had been able to hold the advantage in war against the demons was simple: angels cooperated, trusted one another, and entrusted their backs to their comrades, while demons neither cooperated nor stopped watching each other with suspicion.
That was precisely why demons needed a Demon King. A Demon King to rule them. Before the Demon King who dominated all who belonged to the darkness, demons had no choice but to offer absolute loyalty—and because of that, they could finally trust one another. They were all equally ruled by and forced to submit to the Demon King, so without his command, no one would dare stab another in the back. An ironic kind of trust, born only because everyone's freedom had been stripped away together.
"Irene."
"Yes."
Jae-hyun called her name, then let the hand stroking her belly slide steadily lower, slipping beneath the short skirt of her wedding dress.
"Ah...!"
Irene's pupils trembled as a soft cry escaped her. The moment his fingers began caressing her sex, the urge to roll her hips—already fierce with his cock still buried in her ass—surged higher. She had been desperately holding herself in check for nearly seven hours, and her reason was already at its limit. Watching the women fucking right in front of her had only stoked her further; when his touch stimulated her pussy, she could no longer endure it.
She began rocking her waist and hips on his lap of her own accord, grinding his cock against the lining of her rectum, and every roll of her hips brought such overwhelming pleasure that she only worked herself harder. Watching Irene thrash until her wedding veil fluttered, Jae-hyun rose from his seat—and Irene had no choice but to rise with him. Once he started moving as well, his cock plunging in and out far more fiercely and deeply than when they had been sitting, the pleasure hit her even harder.
"Hah—ah! Jae-hyun oppa... hngh!"
Irene was already dripping with arousal from the anal pleasure, soaking even the pure white stockings sheathed over her long, slender legs. Her beautiful golden hair swayed; her full breasts bounced hard with every thrust. Jae-hyun gripped her heat-flushed ass firmly and smiled to himself.
Irene was his alone. He would never yield her to anyone. The bastard who had dared set his sights on her would never be forgiven. For now he was useful, so Jae-hyun was leaving him alone—but the moment the man's growth was finished, Jae-hyun would kill him on the spot, then use his soul as a battery for dimensional travel, tormenting him for the rest of eternity until he was finally annihilated.
That was the reason a Demon King did not simply kill a hero at once—and instead wished for the hero to grow.
"Hngh, Jae-hyun oppa... me too... I want..."
Even unable to form proper words through the pleasure, Irene was trying to ask him for something—and even if she couldn't speak clearly, Jae-hyun could know exactly what she wanted whenever he chose to.
"As much as you want."
Understanding at once, he created two more clones on the spot. He preferred to take Irene alone, without clones—but if she wanted this, he could yield that much. Of course, he only made that concession because it was Irene. Had Lucien or Selina dared make such a request, he would have punished them on the spot until agonized screams tore from their throats.
Seeing the two clones approach, Irene smiled in blissful anticipation of the pleasure to come. Pregnant or not, she was a Great Archdemon; a little sex was hardly going to make her miscarry. The thought of having all three of her holes claimed at once by the man she loved filled her with fierce expectation.
She was an S toward Lucretia—but toward Jae-hyun, she was pure M.
"Haa... haa..."
The Saint Lucretia staggered on exhausted, ragged breaths. She was still wearing the provocatively altered wedding dress, but there was nothing left of the sacred beauty she had once possessed as a holy maiden. Cum from countless men was splattered across her wedding veil and every inch of her body, dripping in thick trails; the bitter taste of semen still filled her mouth, and her pussy and ass were endlessly forcing out the absurd volume of seed packed inside them.
"Hic... please, stop..."
Utterly spent, Lucretia begged in a broken, weeping voice—her tear ducts so dry she could barely even cry. But a black mage who had not yet tasted her body immediately drove his cock into her cunt.
"Aaaah!"
"You bitch! It's not over yet! There's still a long line waiting, so you'd better service them to the end!"
"Hic... hngh..."
Lucretia struggled weakly in clear revulsion—but the moment the black mage's cock began thrusting into her pussy, moans spilled from her lips and her resistance steadily crumbled. Watching her, the man sneered with satisfaction.
"Heh heh~ You slut. Acting all coy when you love it. Hah! You look like a saint, but you're nothing but a filthy whore! Ngh—god, you clamp down so damn good! Hah, hah! Well, a woman who'll fuck a magical beast and get pregnant with its spawn doesn't need much more said about her... Heh heh~ Hoo! Hah! Then I'll give this cute pregnant saint her eighty-ninth creampie!"
"N-no... I don't want this... someone... Jae-hyun-ssi... I'm sorry... hic... please forgive me..."
In the end Lucretia even called the Demon King's name, desperately pleading for his help—but the eyes of Jae-hyun, who was watching the scene through a clone, were ice-cold. And his true body was currently busy doting on Irene, so he paid Lucretia scarcely any mind at all.
