I Became A Slave To The Mastermind

"Haa… Unni.. a bit more, please.."

"Uh… uhng… beee… hyaap… chuu…"

"Hmm… good girl… my dear Unni…"

"Hyaap… but, Lily… doesn't this feel a bit strange?"

"Huh? What do you mean? It feels really nice."

"Ah… no, I mean… shouldn't this be something done between people who are a bit closer?"

"Then, it's fine, right? Who could be closer than Unni and I?"

"R-really…?"

"Unni, there you go again. It's alright. Besides—"

"We're both girls, aren't we?"

"Huh?"

Chuup—lick—

"Oh. Wha…? Heek?!"

Sephir still couldn't quite grasp what was happening.

Chuu—chuu—

Wh…what is this…?

My… my ear…

"Her tongue… in my ear?!"

Gulp, chuup—

"Hik… hiek… huh?!"

A sound, like a massive wave crashing, resounded in her right ear.

Each time the wave surged, an unknown pleasure overwhelmed her mind, leaving her utterly thoughtless.

"Be-e-haa…"

"Hey… hey! What are you doing? Stop it, right—now?!!"

Squelch—squish—gulp—

'W-what is this..! It's strange! This feeling—it's strange!'

Demons possessed unique appearances, each one different from the next.

Some demons had forms that resembled monsters, others looked like Demihuman, and still others bore a resemblance to humans.

One such example was Sephir.

With a beauty beyond what could be considered human, her appearance closely resembled that of a human.

However, no matter how similar a demon looked to a human, they were never exactly the same.

Take Sephir, for example. Although her body was human-like, she bore distinct demon marks that stood out clearly.

Two horns rose from her head.

Bat-like wings spread from her back.

And—

Ears that couldn't possibly belong to a human, elongated and strange.

"Huh?! My head… my head feels weird?!"

Usually, if someone tried to put their tongue in an ear, the narrow canal would block them from reaching a certain depth.

But Sephir's ear, long like that of an elf, was much wider.

And—

Hera's tongue was slightly longer than an average person's.

"Haa… my tongue… goes all the way in… it's fascinating…"

"What is this?! I don't know… I don't know… I don't understand! It's strange?!"

It felt as though her brain was being directly licked.

Sephir could only tremble, her body jerking uncontrollably in the pleasure that felt like it would break her mind.

Chomp chomp

"Stop!! Pleeease, stop!!!"

But Hera, her consciousness half-faded from the alcohol, couldn't hear her desperate voice.

That day, Sephir was forced to taste a dangerously overwhelming pleasure, one close to despair.

***

The Great Demon Army, led by the Demon King.

In sheer power alone, they possessed a strength superior to any other race.

And leading them were four overwhelmingly powerful figures.

They were the Four Commanders.

Each one possessed abilities in different domains. Yet, one thing remained unchanged—they all had exceptional powers.

And among them, one…

The queen who rules over the succubi, known as the demon of lust or the demon of desire, is none other than Legion Commander Sephir.

Even among succubi, her allure is so captivating that it evokes desire in her own kind. Right now, though—

Shudder

"Heh… Hehehe… Ho-ok…"

Her eyes were rolled back, her tongue sticking out, and her body convulsing on the bed.

If one of her subordinates were to see her in such a state, they would have looked at her with disdain.

Soft breaths—soft breaths

Next to Sephir, who was half-lost in consciousness, Hera was sleeping soundly.

She was clinging tightly to Sephir's waist, nestled close against her.

"O-oh… H-heh… I… come to my… senses…"

Come to your senses, Sephir!!!

Are you really going to crumble like this?

You, called the Indulger of Pleasure… to a mere human?

Hah.

Her eyes, rolled back, showed no sign of returning to normal, and her tongue, extended, had no intention of retreating.

She only gasped, taking in deep breaths through her gaping mouth.

Finally, after what felt like ages of supplying oxygen to her brain, she barely managed to regain her composure.

As soon as she came to her senses, the first thing she did was distance herself from Hera.

"W-what… what on earth is that bitch?!"

What did she eat and grow up on to end up that… seductive?

She glared at her from afar.

Those long eyelashes resting over her closed eyes.

A few strands of black hair stuck to her snow-white cheeks.

Her adorably upturned nose, her cherry-like pink lips.

And just peeking through those lips was… the very voice that had just been filling her ears…

Thump-thump

Sephir's heart began to pound loudly.

For some reason, she couldn't look away from this girl.

'I want to touch her more… no… no…'

She slapped her own cheeks.

"Get it together! The position of the Demon King's direct lieutenant is within reach!"

With trembling steps, she approached the sleeping temptress.

Fortunately, she seemed to be completely asleep, lying still and only exhaling softly.

It was news Sephir was immensely grateful for.

If she tempted her again like she had earlier, she felt she might never come back from it.

"Haa… Normally, one would have to meet eyes to bewitch, but…"

Not confident enough to meet her gaze, Sephir decided to try another method.

"…There's no choice but to force her into submission."

A brutal method that involved injecting her own mana to compel obedience.

Though she'd only ever used her bewitching power to control familiars, she had perfectly mastered the theory.

If the girl's mana proved superior to her own, it would be useless, but…

She didn't believe a mere human could surpass her, a Legion Commander.

Sephir closed her eyes and condensed her mana into a small sphere.

Then she prepared to insert it into the woman's mouth.

"But… this is going to hurt a lot…"

I heard that although I've never experienced it myself, it carries pain so unbearable that death might be preferable.

If one resists until the end, the worst-case scenario could result in their heart bursting.

"Ah… I really don't want to see her in pain…"

Imagining the woman screaming in agony, her body thrashing, brought a sense of uneasy heaviness to his mood.

'No. Why am I even worrying about a human?'

Humans were merely prey for demons. There was absolutely no reason to feel concern.

And yet, even so, Sephir couldn't bring herself to place the mana into the woman's mouth.

"Isn't… isn't there another way? Ugh…"

Standing in front of Hera, holding a condensed orb of mana, she fidgeted nervously.

When she ultimately couldn't make up her mind, she ended up reabsorbing the mana into her own body.

'This method doesn't feel right…'

She felt it was too cruel.

Inflicting a pain worse than death until submission was complete.

This wasn't how she wanted to create a servant.

After contemplating for a while, Sephir finally decided. She would meet the woman's gaze.

Just five seconds.

If she looked into her eyes for precisely five seconds, the woman would become her familiar.

Taking a deep breath and steeling her resolve, she gently shook the woman awake.

'What a pity.'

If it wasn't a spell that required the target's consciousness, she would have forced her eyes open and cast the charm immediately.

"Hey… wake up…"

"Mm… Sis… I want to sleep more…"

As the woman's eyes blinked open in a half-dazed state,

Sephir, without hesitation, met her gaze directly.

"Charm."

At Sephir's incantation, the woman's pink eyes began to glow intensely.

As she continued to stare intently at Hera,

Hera's gaze, fixed on Sephir, started to take on the same pink hue.

The two pairs of eyes began resonating with each other.

'Alright. Now, I'll enter her mind and inscribe a mark in her brain…'

But just as her spell was about to…

Crackle

"Aaagh!!"

Something golden emanated from Hera's body, breaking the resonance between them, and then poured down upon Sephir.

"What… what is this?!"

Sephir unfurled her wings, barely dodging in time, as dozens of golden mana spears struck the ground where she had been standing.

Once her startled heart calmed down, she could finally grasp what had happened.

'Was that an attack directed at me…?'

If she hadn't dodged, she would have suffered a significant injury. Could it be that woman attacked her?

But no matter how she looked, it didn't seem like

She was too drunk to even pull herself together, so there was no way she could unleash such a sophisticated attack.

"Plus, this mana… it feels familiar somehow…"

Huh.

It was a type of mana she'd seen many times before. This golden color was incredibly familiar.

The person who wielded this color of mana was…

As the owner of the golden mana came to mind, his body started trembling.

"Ho… ho… could it be… Athena?"

Yes. The only person who possessed this sun-like golden mana was none other than her.

The puzzling part, however, was why her mana was within this woman's body.

'Could it be that she shared her power?'

That possessive woman? Her power?

It was an unbelievable situation, but if that wasn't the case, there was no other way to explain what was happening.

"W-wait a minute…"

There was one thing he'd overlooked due to the confusion of the situation.

If the owner of this golden mana was indeed Athena…

The moment the mana activated, some kind of signal would have reached her.

Upon receiving that signal, she would know this place's location.

And if that happened, this place would no longer be—

"…Found you."

An empty voice that stirred up primal fear.

Sephir's head turned with a creak, like a broken clockwork doll.

When she looked at the voice's owner, she found herself frozen in place, unable to move a muscle.

Why?

The expression on her face standing before her—

"This… wretched woman… how dare you…"

"H-hic…"

She felt more terrifying than the Demon King.

It seemed that his story would end here.
