I Took A Succubus's First Time

Kouhei and Yuuna walked slowly down the dimly lit hallway, their footsteps echoing faintly off the ancient stone walls.

Kouhei had absolutely no clue where they were headed, but Yuuna had only smiled and told him to follow her—so he did, without a second thought.

There was something strangely comforting in just watching her from behind with the way her long, silky hair caught the flickering torchlight, and how the dark fabric of her dress clung gently to her elegant frame.

He simply trailed after the beautiful demonic vampire, Sarushima Yuuna, whose mere presence seemed to make the air feel heavier… and somehow sweeter too.

"Kouhei-kun," Yuuna spoke, her voice breaking through the quiet. It was softer than usual, tinted with something that felt almost wistful. "You know, I would've never imagined something like this happening."

"Huh? What do you mean by that?" Kouhei asked, glancing at her face, which seemed oddly serious.

"Me… walking here with you. In Hell. The place where I was born," she said, her gaze distant, eyes reflecting the dark red glow of the corridor.

It made sense, Kouhei thought, that she wouldn't dream of something like this. Hell wasn't just a dangerous place—it was pure madness to any normal human.

The suffocating, chaotic mana that drenched the air could shatter a human mind, crush it under its weight, and kill them in moments.

That Kouhei was here, beside her—even if he wasn't exactly human anymore—was nothing short of impossible. And strangely, that impossibility seemed to warm Yuuna's heart from within.

"You know," she continued, her voice a low murmur that seemed to blend into the eerie hum of the mana around them, "Hell might be a horrible place to most. Enough to drive someone insane." Her eyes softened, almost glowing. "But there's a kind of beauty to it too. It's not just endless violence and bloodshed."

Then, wordlessly, Yuuna walked forward, the train of her dress sweeping over the cold floor as she stepped out onto the castle's stone balcony.

Kouhei followed, the air growing cooler as he joined her side.

"Sometimes," she whispered, almost as if she was sharing a secret, "even Hell can be beautiful."

And for a heartbeat, Kouhei forgot to breathe.

What spread out before him was something he could've never imagined.

The sky above them was a deep, roiling red, dark yet alive—like it pulsed with a hidden heartbeat. A pale moon hung high in that crimson expanse, spilling silver light over the jagged land below, where rivers of black stone twisted through crimson soil.

It was haunting. Ethereal. And beautiful in a way that felt almost painful to look at.

His chest tightened, a strange awe bubbling inside him.

It wasn't the human world. It wasn't even close. But it was mesmerizing.

Yet what truly stole his breath wasn't the hellish sky or the blood-colored earth—it was Yuuna herself.

With the moonlight draping over her dark dress and her pale skin, she looked almost unreal. As though she belonged to that otherworldly scene.

Against that backdrop, her beauty felt sharper, almost blinding, making everything else seem dull and distant.

"It's beautiful, right?" Yuuna asked softly, her eyes still on the horizon.

"It is," Kouhei replied, his voice quiet, but then his gaze shifted to her. "But you're much more beautiful, Yuuna-san."

Yuuna turned her head, her crimson eyes meeting his. Surprise flickered across her face for just a moment before it softened into a warm, glowing smile.

"I was talking about the view, not me… but I do appreciate that," she said with a soft, amused laugh that made his chest feel oddly light.

For a while, they stood in silence. The sound of distant wind and the ever-present thrum of mana in the air filled the quiet.

Then Yuuna's voice broke through, hesitating, almost shy. "Hey, Kouhei-kun."

"Yeah?"

"Do you… want to kiss?"

Her words landed softly, but they stirred something deep in him.

Caught off guard, Kouhei didn't answer—he just leaned in, closing the small space between them until their lips met.

The kiss was gentle at first, as if both of them were afraid it would shatter.

Yuuna felt something different in him—something she couldn't quite put into words, but it made her heart throb harder in her chest.

When she pulled back, she studied his face, noticing something odd.

"Did you get even taller?" she asked, her voice tinged with playful curiosity.

She was right. Before, she hadn't needed to tiptoe to kiss him, but now she had to stretch just slightly.

"Did I? I don't really feel like it," Kouhei chuckled, scratching the back of his neck.

"Silly," Yuuna teased gently, stepping closer and resting her head against his chest. "You've changed so much while I wasn't around… and you've become so much stronger."

She went quiet then. Her lips parted as if to speak, but no words came out right away.

"Hey, Kouhei-kun, I…"

Her voice trembled for a second, like she was afraid of what she was about to admit.

"I really love you, you know?" she whispered at last. "When I was in Souichiro's hands, I kept thinking… maybe if he was going to torture me, I should just bite my tongue and end it so he couldn't do anything he wanted with me."

"Please don't do that," Kouhei replied firmly, his words gentle yet unwavering. "No matter what happens, I'd do anything to save you."

Yuuna's heart seemed to bloom at those words, opening like a fragile flower warmed by the sun.

It amazed her how deeply she'd changed.

She had been raised to wear a smile that hid her cruelty, to lead others while burying her twisted, ugly heart.

She'd believed she was evil—someone meant only to hurt, someone who should never love or be loved.

But meeting Kouhei had broken something in her… and rebuilt it into something softer and something real.

"Kouhei-kun… can you have sex with me?"

Kouhei's eyes widened, caught completely off guard by how direct she was.

"Here?" he asked, his voice cracking slightly, the surprise plain in his expression.

"Well, it's not like you don't want to, right?" Yuuna teased, her voice low and teasing, yet tender. "I can practically feel your life force bursting right now."

"W-Well… Yuuna-san is really beautiful tonight, so…" Kouhei stammered, his face heating up as he glanced away.

It was embarrassing that she'd noticed he was already so hard, but the truth was, how could he not be? Yuuna tonight was beyond beautiful—so breathtaking that it was hard to think of anything else.

"Fufufufu… it's been a while for me too," Yuuna murmured, her words soft yet edged with a quiet longing. "I haven't had sex with you in so long. I imagine you've been with the others plenty, haven't you?"

"W-Well, we did… as a matter of course," Kouhei muttered, scratching his cheek in embarrassment.

Yuuna smiled gently, her eyes half-lidded, her lips curling in amusement. "I'm already wet right now, you know? Just being here with you… it's enough to make me wet."

Then, Yuuna pulled Kouhei in again, her fingers curling around the back of his neck as their mouths crashed together. This time, there was no hesitation with her tongue slipping past his lips, hot and slick, dancing hungrily against his.

Their tongues twisted and tangled in wet, messy circles, breaths growing ragged and shallow. Each movement felt electric, sending small shocks down Kouhei's spine. The moonlight above them spilled across their faces, catching on the thin strings of saliva that stretched between them when they barely pulled apart to breathe.

It felt dizzying—like being drunk on nothing but each other's taste. The pounding of his heartbeat echoed in Kouhei's ears, drowning out everything else.

After what felt like both an eternity and no time at all, Yuuna slowly pulled back, her lips glossy and slightly swollen.

"Here, Kouhei-kun…" she murmured, voice low and breathless, her words dripping with something dark and sweet.

She turned away from him, the curve of her back catching the cold silver light of the moon. One hand reached forward, gripping the rough, ancient stone railing of the balcony for balance.

With her other hand, she gathered her skirt, lifting the dark fabric up around her hips, revealing soft, pale skin and the delicate curve of her ass. She hooked her thumbs into her panties and dragged them down until they bunched loosely around her thighs.

Then, shamelessly, she spread her pussy open for him, revealing folds slick and glistening with thick globs of clear wetness. The droplets gathered, heavy, before falling to the cold stone floor with quiet, obscene sounds, pooling beneath her.

"Fuck me until it's sloppy," she whispered, her voice rough and needy, each syllable quivering with hunger. "Mess it up so much that it's filled with your sperm."

Kouhei's throat tightened, his breath caught.

The sight of her—exposed, offered up to him without an ounce of shame—hit him so hard it was almost painful.

Ignoring her now wasn't even an option. It felt like it would be a betrayal of everything inside him.

It was almost a crime against himself.
