Joining the Demon Army Changed My Life (2)

"Ugh... Haaa..."

Ria ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠was quite skilled, as expected of a succubus. Her tightness was remarkable, and the moans that pleased the ears were equally delightful.

'At this rate, I'm going to cum soon.'

It had already been over ten minutes since penetration. That was more than enough to shake off the stigma of being called premature.

"Turn around."

Ria, ever the perfect attendant devoted solely to me, obeyed without hesitation.

As a demon, the succubus had two luscious horns befitting her race.

'I kind of want to grab those horns and thrust.'

Since ancient times, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠horns had made excellent handles for fellatio.

But honestly, there was something else I wanted to try even more. Something those damn Hero Party bitches never did.

A proper blowjob.

When I pointed at my cock with my hand, Ria immediately lowered her head without hesitation.

"Wait, hold on."

Before the blowjob, there was something else I wanted to try first.

I gently cupped Ria's cheeks and slowly pressed my lips against hers. Partly because it felt good, but mostly because I thought a kiss would be better before she took my cock in her mouth.

"Hmm, ugh."

Our tongues began tangling stickily, Ria's tongue slowly entering my mouth.

Our tongues wrestled as if in battle, exploring each other.

I slowly stroked ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Ria's soft back as I continued the kiss. When we finally pulled apart, strands of sticky saliva stretched between us.

Naturally, even that looked incredibly erotic—just what you'd expect from a succubus.

"Shall I use my mouth now?"

Ria replied with a smile. She immediately knelt before me and took my cock into her mouth.

She didn't even use her hands. Was this just how succubi were?

"Slurp, schlop, lick."

As my already rock-hard cock began to be slowly stimulated by her soft tongue, I could no longer hold back. I felt like I'd cum any second now.

'Her tongue skills are no joke.'

Honestly, it almost felt like her goal was to kill me through overstimulation. Ria's tongue work was deadly serious, slowly licking from the very base of my shaft all the way to the tip.

"It's so big, my jaw might dislocate...~"

It didn't sound like a complaint. If anything, the way she said it while being completely engrossed made me almost afraid.

'Are all succubi like this?'

No wonder they were succubi who fed on essence—they clearly weren't just for show.

The sensation of Ria's throat wasn't much different from her pussy that I'd penetrated earlier. It was as if she had special muscles to constrict her throat, allowing her to adjust the tightness remarkably well.

"Ria? I-I'm gonna cum."

"Please cum as much as you'd like."

With Ria's permission granted, I immediately came in her mouth.

Splurt! Splurt!

Ria took a deep breath and swallowed it all in one gulp. I could clearly hear the sound of it going down her throat.

"Thank you for the essence. If you ever need me again, feel free to call anytime."

It seemed my recent ejaculation had quite the positive effect on her too. I could feel her demonic energy had grown thicker than before.

'Damn, the Demon Army's benefits are insane.'

I should've ditched that Hero Party crap and joined the Demon Army way sooner.

Now I found myself curious about the pussies of countless other succubi besides Ria. The one I was most curious about was the Succubus Queen.

'I'll definitely fuck her someday.'

In a world where strength ruled, all I needed was to become stronger than her.

As Ria adjusted her clothes and started to rise, she reached into her bosom as if she had something to give me.

What she pulled out from what looked like her panties was a pill.

The pill felt slightly damp in my hand. It seemed soaked in her juices.

"What's this?"

Holding the suspicious pill, I looked at Ria. With an utterly expressionless face, she began to explain.

"It's a Demon Pill given by the Demon King. If you take it, your body will transform into that of a demon."

"A Demon Pill?"

Well, if the Demon King gave it, it probably wasn't bad.

Without hesitation, I swallowed the pill. Shortly after, my body began to slowly burn up.

My entire body started glowing ominously. My skin grew slightly paler. And then came an excruciating pain, as if something was tearing through my skull.

"Gaaah!"

After enduring the brief ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠pain, I reached up and felt a blunt protrusion.

"Success. You've grown demon horns."

"Horns."

They were still small, but not bad.

"When do they get bigger?"

It was a bit disappointing that they were still tiny, like a baby demon's.

"If you diligently accumulate demonic energy, they'll grow quickly. A demon's horns are proportional to their demonic energy, after all."

That must be why the Demon King's horns were the largest.

"Ria, I'm heading straight to the human realm. Do you plan to come with me?"

Ria nodded her head.

"I am the Grand General's attendant. If it is your wish, I will do anything..."

"So you'll do anything I want?"

"Yes, that's correct."

Holy shit, she's amazing.

"Then can you call me 'big brother'?"

"If you wish."

"Go ahead."

Ria cleared her throat briefly before composing her voice. Immediately, an enchanting, honeyed tone flowed out.

"Big brother."

"Good."

Though it felt slightly burdensome.

"That's enough for now."

"Understood."

She truly was obedient to a fault.

***

In my heart, I wanted to depart for the human realm immediately.

Because I wanted to see those damned bitches' faces even a single day sooner.

But the Demon King summoned me.

"Yes, Your Majesty."

The Demon King was always seated upon the central throne. From a distance, he appeared like some massive monstrosity.

'Something tells me that's not his real form.'

Just his voice alone boomed resonantly in my ears—clearly infused with magic.

'Someday when the opportunity arises, I'll make it my business to see the Demon King's true form.'

For now, the reason he called me was what mattered.

"What did you summon me for?"

Unlike yesterday, today I was filled with love and reverence for the Demon Army.

'No wonder humans couldn't easily conquer this place.'

Their military strength alone was absurd. And their internal welfare system was even more ridiculous.

Humans never stood a chance from the beginning.

"I thought I'd gift you a weapon."

"A weapon?"

"Indeed. You can no longer wield your original weapon, can you?"

"Ah..."

I hadn't considered that. The weapon I once wielded was the Holy Sword, bestowed upon the Hero of the Age.

Naturally, now that I'd become a demon, not only could I no longer use the Holy Sword, but it had undoubtedly already abandoned me.

"Were you originally a swordsman?"

I wasn't particularly picky about weapons.

It wasn't like I had any special sword techniques anyway. I'd just invested in my stats and relied on the Holy Sword's power.

"No. I can use any weapon equally well."

Moreover, thanks to the skill 'King of All Weapons' I'd acquired after reaching 50 Physique, I could wield any weapon with equal proficiency.

"Excellent. Then I shall bestow upon you a Demon Sword."

"A Demon Sword!"

As the name suggested, Demon Swords were often comparable to Holy Swords in might.

And if it was a sword personally bestowed by the Demon King, it would undoubtedly surpass even the finest legendary blades.

"Ooooh!"

I immediately activated my Emotion Skill—one I'd obtained from the gacha system during my single attempt at it.

[Demon Sword Tyrfing]

A blade imbued with the power of demon gods. By consuming demonic energy, it allows the wielder to unleash magic unique to the demon race.

It wasn't yet clear what unique magic I could wield with it. But the mere fact that it granted demonic magic was immensely satisfying.

'Demonic magic can't possibly be weak.'

At the very least, it was bound to be fearsome.

Moreover, the sword itself looked incredibly sturdy. Perfect for someone like me who relied purely on physical prowess rather than technique.

[You have obtained a Demon Sword. Physique +10. Agility +10.]

'The passive effects are substantial too.'

This was the first piece of equipment that boosted my stats just by possessing it. Even that damned Holy Sword didn't have such an effect.

'Status Window.'

[Kim Jin-woo]

[Physique:81, Agility:81, Magic Power:71, Virility:51]

Satisfactory stats. It wouldn't be long before I caught up to my original stats of 100.

"Thank you, Your Majesty. I swear upon your feet, I will make humanity kneel before you."

"Hahaha! Splendid!"

And so, I set out for the human realm leading one of the Demon Army's legions.

Accompanying me was one of the Four Heavenly Kings—the Succubus Queen.

Naturally, our first destination was the Church beneath the Empire's capital, Stein. It was where I'd been appointed as the Hero, and the central land of the Human Alliance.

It was also where the newspaper that had spread rumors about me being impotent was headquartered, along with the Church to which Saintess Beatrice—one of the candidates—belonged.

A thoroughly wicked organization that needed to be utterly crushed.

"She's probably here."

After the Hero Party disbanded, the only place she would have gone was the Church.

I could already smell the saintess's scent carried on the wind.

"Grand General, we'll be arriving shortly."

"Good, understood."

I gave a light nod.

There was yet another reason why the Demon Army's welfare was top-tier.

Back when I was the Hero, I had to ride horses or walk during travels—but the Demon Army provided wyverns for transportation.

'Holy shit, this is the best!'

It made me realize anew why people should always side with the stronger faction.

"Shall we advance immediately?"

The demons looked ready to charge at the slightest command. Truly fitting for beings who loved blood and slaughter.

We needed to demonstrate the Demon Army's majesty. And the demons who'd been holding back all this time deserved some time to play.

"Alright! Let's go wild for a bit!"

"Wooooooh!!"

"Everything for the Demon King!"

It was time for the former Hero to receive punishment for branding me with the disgraceful label of premature ejaculation.
