I Took A Succubus's First Time

The wedding ceremony between Souichiro and Yuuna was already in full swing.

Demonic weddings were a far cry from how humans did them.

In truth, all they truly needed was to hold a ceremonial gathering, invite everyone they wished to witness the vows, and then consummate the marriage afterward—and that alone sealed their union for eternity.

Right now, Yuuna stood motionless before the towering double doors of the grand hall where the ceremony awaited.

A thousand thoughts raced through her mind, each twisting tighter than the last.

Inside, a gathering of powerful noble demons was waiting.

Since the Sarushima House stood as one of the Great Houses, it was only natural that the highest-ranking demons and ancient nobles had gathered to witness this day—especially because both bride and groom were next in line to inherit the Sarushima name. Those bound to the House by allegiance or ambition wouldn't dare let this moment pass unseen.

Yuuna stared at the doors, the ornate carvings glaring back at her like silent judges.

Once she stepped through, there would be no escape.

The ceremony would begin in earnest.

She could still turn and flee, her legs carrying her far from this hall and everything it meant.

But then what?

She would only end up hurting Kouhei again… carving a deeper wound into someone who had already suffered so much because of her.

So, she clenched her trembling hands and prepared to bear the weight alone.

She had to take the fall.

Drawing in a shaky breath, she pushed the doors open.

And in an instant, she was swallowed by the blinding brightness of the hall and the roar of countless voices.

The room was alive with luxurious fabrics, flickering braziers casting dancing shadows across marble floors, and rows upon rows of gathered demons, all turned to look at her. The air seemed to crackle with heat and whispered power.

She recognized many faces among them.

They were demons of rank and might—lords and ladies whose very presence weighed on the space around them.

All of them had gathered to witness the union of Yuuna and Souichiro.

As she stepped forward, the eyes of the hall followed her every move, heavy with scrutiny and thinly veiled hunger.

Then, slowly, applause rippled across the room like a rolling wave.

"Here comes the bride!"

Voices rose in chorus as Yuuna walked the aisle, the sound echoing in her ears like distant thunder.

She was breathtaking.

Her eyes reflected the fierce resolve and grace of Sarushima leaders past, and the quiet, regal aura wrapped around her slender form spoke louder than words.

Even the most stoic among the crowd could not hide the flicker of awe in their gaze.

Yuuna's heart felt like it might break through her chest, but she kept her true feelings hidden beneath a carefully cultivated mask.

Her usual expression curved gently over her lips.

It was the smile she had practiced to perfection, worn countless times to hide the storm that raged behind her eyes.

At the far end of the hall, Souichiro stood waiting.

His gaze locked on her, but not with love.

Instead of admiration, all he saw was an object, like a delicate toy waiting to be shattered.

To him, Yuuna was nothing more than something to be broken and used.

Beneath his elegant posture lurked something twisted. It was a hunger driven by sadism alone.

As he watched her walk closer, a faint curl tugged at his lips.

Tonight, he would peel away that mask, layer by layer, until her misery lay bare before him.

No.

For now, there was no despair on her face.

Not yet.

But he had no doubt the mask would crumble under him when they were alone in the darkness.

He would enjoy every second of it.

But for now, as form demanded, he had to wear his own mask—the gentle, doting brother.

"My dear sister, you're as beautiful as ever," he murmured, his voice calm and warm on the surface.

Inside, Yuuna's chest tightened, bile rising in her throat.

She forced herself to keep her expression steady, swallowing the disgust that burned behind her practiced smile.

His words dripped with rot.

Souichiro caught the brief flicker of revulsion in her eyes, but only shrugged slightly, as though amused.

"Well now, why don't we sit together and wait for the announcement of our marriage to begin?" he suggested, his tone dripping with mock kindness.

Yuuna didn't look at him.

Without saying a word, she moved past and lowered herself into her seat.

Souichiro watched, a thin smile twisting his lips, half amusement, half dark promise.

And so, the wedding ceremony began.

One by one, demons came forward—nobles cloaked in dark silks and adorned with bone-carved jewelry—offering polite congratulations, hushed words, and gifts heavy with meaning.

And then, one figure approached, bearing something that made the air around them shift.

"Since it wouldn't be a proper wedding without consummation," the demon said smoothly, a faint smirk dancing on his lips, "I thought I'd gift you something special."

Reaching into his robes, he produced a small glass bottle and placed it on the polished table before them.

A pale liquid glimmered inside.

"This," he explained, voice low and deliberate, "is an aphrodisiac made from mermaid's blood. It's potent enough to, you know…"

He paused, then made a crude gesture—fingers forming a circle, the other hand's finger thrusting in and out.

"And you'd be at it until dawn," he continued, voice calm despite the heat in his words. "Honestly, I wouldn't be surprised if you kept doing it until the next day. One sip of this could even drive a succubus insane. So I'd gladly have you take it."

"Hmm… an aphrodisiac, huh?" Souichiro drawled, resting his chin on his fist, eyes fixed on the bottle. "So just a single sip would turn me into something like a starving succubus? I don't love the comparison… but sure, I'd take it. Though I have to wonder… what if I drank it all?"

The room seemed to still for a heartbeat.

"I wouldn't suggest that," the demon replied, voice growing grave. "You'd go mad with lust—utterly insane—and you wouldn't stop until you had wrung every drop of relief. It could be dangerous to your partner… the effect might stretch to days, maybe even weeks, until your hunger's finally sated."

For a heartbeat, silence.

Then Souichiro's mouth curled into a slow, wicked grin.

It was a devilish smile that chilled the air itself.

To him, this was no warning.

It was an invitation.

"I see… I'll gladly take it. I appreciate the gift," he said, voice smooth, almost polite.

"Thank you," the guest said, nodding slightly.

Yuuna sat rigid, every muscle tight.

She could already see what Souichiro would do.

He would drink the whole thing.

And he wouldn't stop until he had fucked her over and over, until his lust had wrung every drop of resistance from her body.

Yuuna had braced herself for this nightmare.

Yet, despite all the steel she had forced around her heart, a faint tremor of fear still coiled in her chest.

Then, after a while, it was finally their father's turn to speak.

"I don't have any words other than that I would be leaving the Great House of Sarushima to you two once you are both ready," he told them, his voice deep and unwavering. "And then I would trust you two to become someone worthy of the Sarushima name, so you can bring more prosperity to this house than your mother and I ever could."

It was, in truth, a beautiful speech.

It was dignified and filled with hope.

But the weight of it felt twisted, almost cruel, given the reality of this ceremony.

Time flowed forward relentlessly. More and more guests stepped forward, congratulating them, bowing politely, offering gifts wrapped in fine silk and dark velvet. Faces blurred together, words became echoes.

And slowly, Yuuna could sense it.

Something was shifting.

She turned her gaze sharply to the east…

She felt it. No—everyone felt it.

"W-What is that…?"

"T-That power? What…?"

A sudden, overwhelming presence had just appeared from nowhere—bursting forth in shockwaves that seemed to shake the air itself.

Yuuna recognized it instantly.

While everyone else looked around, puzzled and anxious, Yuuna alone understood what was truly happening in that moment.

It was Kouhei…

And he had just formed a Connective Love Link with the others.

Staring in that direction, Yuuna's hand tightened around the armrest of her chair, nails biting into the polished wood.

'Please… Kouhei-kun… don't do it…'

She silently pleaded, her chest twisting painfully.

***

Outside, while the celebration pressed on inside the Great House of the Sarushima, something else was unfolding beyond the walls.

"Huh? Are those bastards seriously planning to start a war right now? Are they out of their fucking minds?" a guard muttered under his breath, eyes narrowing.

He stood atop the watchtower, cold wind tugging at his clothes, staring out across the distance.

An army was advancing toward them—shadows crawling over the land.

"Considering there are other high noble demons inside who've got entire armies stationed here... are they really dumb enough to plan an attack now?" he scoffed, voice low and rough.

"Keh. Idiots…" he spat, rolling his eyes as his hand moved toward the heavy bronze bell beside him.

He wrapped his fingers around the worn rope, ready to ring out the alarm that danger was coming straight for them.
