I Took A Succubus's First Time

Kouhei and Hina stepped into the infirmary, the heavy metal door creaking shut behind them.

The fluorescent lights above flickered once before stabilizing, casting a sterile white hue over the empty beds and curtains.

Their footsteps echoed faintly against the linoleum floor, and behind them, just a few paces back, came Hiyori.

She was quiet, but clearly not hesitant. Her presence loomed like a shadow Kouhei couldn't shake.

Kouhei felt a tightness in his chest. This wasn't nervousness from anticipation.

No, this was far more complicated.

'What am I doing here?' his thoughts screamed. 'I've had sex before—even with someone watching… but this? This is on a whole other level. Ichinose-san… she's human. She's not just some stranger or voyeur… she's someone I've known for years.'

He'd done things in the past, sure. Kinky things. Risky things.

But somehow, this felt far more vulnerable. Far more real.

The embarrassment wasn't just skin-deep—

It was crawling up his spine, tightening around his neck like a rope.

He'd tried to talk Hiyori out of this and tried to nudge her gently away, but she didn't budge. Not even a little. Her eyes carried resolve, and her silence spoke louder than any protest.

And that—

That was what made this so damn unsettling.

He was about to have sex with Hina, while Hiyori—someone he had known for two years—stood there and watched.

This wasn't a fantasy, this wasn't even staged. This was actually happening.

His throat dried out just thinking about it.

"For starters," Hina's voice cut through the tension like a sharpened knife, soft yet firm, "why don't you kiss me… and lead me to the bed, Kouhei?"

There was a faint teasing lilt in her tone, but nothing about it felt playful.

She stood calmly, eyes closed, lips slightly parted, like she was offering herself without hesitation.

Did she know what he was feeling right now?

Maybe.

Or maybe she was pretending not to notice.

Kouhei's throat bobbed as he swallowed hard, glancing at Hina… then sideways, toward Hiyori.

She stood with one arm crossed tightly beneath her breasts, the other hand gripping her bicep, fingers white from the tension.

Her eyes were wide, her face stiff.

What was she feeling? Was she jealous? Curious? Confused?

He didn't know. And right now, he couldn't afford to dwell on it.

No more second-guessing. And no more hesitation.

He took a deep breath—and leaned in.

Their lips met.

The kiss started soft, but it escalated quickly.

Their mouths parted, tongues slipping in, swirling, dancing in each other's warmth.

The taste of her breath mixed with his, forming something intoxicating.

It was like a drug made from desire.

It was wet. Hot. Intense.

And Hiyori saw everything.

She saw the way Hina's tongue glided across Kouhei's, how her lips pressed against his with so much need that they looked like they were trying to melt into one another.

They forgot about the room. Forgot about her.

And she was just… standing there. Watching.

When they finally broke the kiss, a long, glistening string of saliva stretched between them, connecting their lips for a moment longer before snapping and falling onto Hina's chest.

Then, Hina turned her gaze—slowly—toward Hiyori.

Her eyes sparkled mischievously.

Her cheeks were flushed, glowing with a mixture of arousal and satisfaction.

And Hiyori? She looked like she'd just walked in on something forbidden. Her face was red, lips slightly parted in disbelief, like she was struggling to process what she'd just seen.

It was the kind of expression someone would have after witnessing something far too lewd for their untainted eyes.

"Now then…" Hina whispered, licking her lips slowly, sensually—like she was savoring his taste.

She grabbed Kouhei's hand and gently tugged him toward the nearest infirmary bed, her movements fluid and unhurried, but laced with eagerness.

"Wait, calm down a bit, Hina-san," Kouhei stammered.

"I can't wait," she replied instantly, her tone as calm as it was bold. "I'm pretty horny right now."

And just like that, the atmosphere changed.

Her blunt honesty hit harder than anything else she'd said.

It was surreal... hearing her say something so lewd and explicit with such an emotionless, straight face. Like this was routine for her. Like fucking was as natural as breathing.

She began undressing—casually and confidently—each piece of clothing peeled away like layers of an irresistible temptation.

Her hips began to grind into his slowly and deliberately, pressing heat against his own.

And all the while, she kissed him again, her lips tracing his, her tongue darting into his mouth, her breath hot and unrelenting.

The air in the infirmary changed—

It thickened.

The scent of her arousal spread like a haze, and it was impossible to ignore.

A mix of sweat, pheromones, and the intoxicating fragrance unique to a succubus in heat. It clung to the air, invading Kouhei's senses and making him dizzy.

Was she doing this to provoke Hiyori?

Was this all an act to assert dominance?

He couldn't tell.

All he could feel was the pressure of her body against his and the weight of her stare as it bore into his soul.

"Fufufu…" she chuckled lowly, each syllable coated in mischief and lust.

She moved like a predator—no, like a succubus.

Graceful.

Dangerous.

Desperate to devour.

Watching this unfold, Hiyori could hardly believe what her eyes were showing her.

This was Hina—the so-called Ice Queen.

The girl so many fell in love with after just one look.

The one who was untouchable, above it all.

And now she was acting like this?

Anyone who saw this side of her would be stunned into silence.

While Hiyori's thoughts spiraled, Hina was already positioned—

Her face was hovering just above Kouhei's crotch.

Her fingers were curled around the waistband of his pants, her eyes locked onto the bulge beneath.

Then, with a swift tug—

"Ah…!"

Hiyori gasped aloud, both hands twitching in shock.

Because the moment Hina yanked his pants down, something leapt out.

It wasn't just big—

It was massive.

The thick, veiny shaft sprang forward with a weight and presence that made Hiyori's jaw go slack.

There was a subtle sheen to it, a raw pulsing energy that made it look almost majestic.

It was made of flesh, yes—but no part of it looked soft.

It stood tall and proud, the hardest, most intimidating thing in his body.

'What is that?!' Hiyori screamed internally, her heart pounding.

It wasn't just a penis.

It was a thing.

A single-eyed snake.

Only—it was stiff.

Impossibly stiff.

Rigid like steel.

Unforgiving like stone.

And terrifying in a way that sent shivers down her spine.

Hiyori had never seen anything like it.

She didn't know love until Kouhei. She didn't even understand what true desire was until recently.

And sex?

That was something she hadn't even dared to think about.

But right now—right in this moment—it was impossible for her eyes to look away from that towering meat spear.

She gulped hard.

Her lips quivered slightly, and she instinctively clenched her fists by her sides.

Hina turned to look at her—and Hiyori flinched.

That gaze… it was sharp. Almost like she was being pushed—cornered—by just a glance.

Hina wrapped her hand around the base of Kouhei's dick.

The way she held it... it was clear she was used to handling it.

From the tip, a thin stream of clear fluid was oozing out.

Hiyori couldn't help but gulp again.

For some reason, her mouth started to water.

"I'm going to show you just how much you don't measure up to be someone worthy of Kouhei, Ichinose Hiyori," Hina said, her tone cold. "Watch this."

"Hina-san, I don't think we have time for this kind of stuff," Kouhei said. "Aren't we supposed to be performing the love link?"

"You don't need to worry. We'll still get it done," Hina replied calmly.

"But it sounds like you're more focused on provoking Ichinose-san than actually getting anything done," Kouhei said, frowning.

"I'm going to push her buttons harder," Hina responded. "So she doesn't even think about going after you."

Kouhei couldn't understand why Hina was acting like this.

Honestly, it was kind of concerning. Her behavior didn't feel like it came from confidence—it felt more like envy. Like she was insecure about Hiyori.

It was almost as if... she still hadn't let go of the idea that he might return to his old world.

A world where none of this—demons, magic, love links—existed.

A world of normalcy.

"You really are hopeless, Hina-san," Kouhei said.

"Huh?"

Suddenly, before she could react, Hina found herself on her back.

Kouhei had flipped her underneath him. Now she was the one lying on the bed, staring up at him in surprise.

"Kouhei…?"

"Hina-san… I'm going to make sure you forget the idea of me going back to normal," he said, eyes locked onto hers. "So I'm going to write it all over you."

With that, he reached for his belt and started tying Hina's wrists to the bedframe.

The leather slid against her skin, the click of the buckle echoing with finality.

And Hina's breath quickened.

Not from fear.

But from anticipation.
