While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 92: The True Monster’s Name

Chapter 92: The True Monster’s Name

“The movie was fun, huh?”

“…Yeah.”

He was on a date with a beautiful girl with long black hair, officially his girlfriend in public.

On the way to a park on the outskirts of town in the evening, as the date was winding down…

He was about to suggest parting ways for another appointment.

“—Ngh!?”

Suddenly, someone pressed a damp cloth over his mouth, and he turned in panic.

“Takuya. Just sleep for a bit.”

A cold, almost detached voice whispered an apology.

It was her—the Vice President, his right-hand at school—no, Karin Hanazawa, staring at him with hollow eyes.

“…Sorry.”

“Why…?”

Shocked by her audacity, despite her tolerance of his countless affairs, Takuya Yasuoka inhaled through the cloth and lost consciousness.

“—Ngh, what’s… this place…?”

When Yasuoka awoke, he was in a dim space, like a residential garage or a partitioned room in an abandoned factory.

A single bare bulb hung from the ceiling, revealing an old or cheap building.

It was unfamiliar yet strangely familiar.

And, above all—

“—Ngh!? What the hell!?”

Stirring violently, he noticed the clanking of his restrained limbs and froze.

“Hand…cuffs!? Wait, I was—”

Slowly piecing things together in the dimness, he began to understand.

“I was with Karin…!”

During their date.

She’d slipped behind him, pressed a cloth to his mouth.

While he was unconscious, he’d been restrained against a wall in an awkward position.

“Damn…! What the—!”

His hands were cuffed behind him.

His legs, seated with knees bent inward, were chained to stakes in the wall, his toes barely off the ground, preventing him from standing.

“What… the hell…!?”

Panicking, thrashing, shouting.

His heart pounded like a racing drum.

Blood rushed to his head, a dizzying sensation.

At the edge of his strained awareness, he saw—

“…Takuya.”

“Karin…?”

One of the women he was dating, likely the longest-standing one.

His right-hand at school, the Student Council Vice President, a beautiful girl with long black hair and sharp features—Karin Hanazawa herself.

“…Stop this nonsense.”

“Nonsense, you say?”

Karin parroted his words, eyes wide, staring down at him from two meters away.

“Getting your lackeys involved, planning to seduce those underclassmen… Onodera and Tsukimi. I don’t think I’m the one pulling nonsense here…!”

“…!!”

How does she know? Yasuoka swallowed the question.

That “plan”—to sleep with the underclassmen girls, break up their relationships, and make them dependent on him—was shared only with select lackeys.

He’d been careful to hide it, treating it like hunting sheep or slaughtering livestock, effortless and carefree.

Using people he held leverage over—men, women, anyone who couldn’t defy him—he’d progressed slowly, surely, secretly.

So why—? He itched to check with his lackeys via his phone, but—

“It’s fine now.”

“…!”

Feeling the despair of his missing phone, he was startled by Karin’s resigned tone and met her hollow gaze.

“I realized something.”

“What…?”

He hadn’t anticipated her taking such drastic, direct action, crushing his options.

He’d seen women lose control plenty of times in his life.

But this—

“You kept cheating despite being with me. So… I’ll just do whatever I want, too.”

“Whatever… you want…?”

Yasuoka was confused.

And then—

“What the—!?”

Karin suddenly began removing her pleated skirt, startling him.

“What are you doing!?”

“Does it matter?”

She started pulling down his pants, throwing him further into disarray.

“This is tough to get off…”

“…Huh?”

With a displeased expression, Karin stepped away, grabbed a pair of scissors from a nearby bag, and returned.

“!?”

As she aimed the scissors at his crotch, his eyes widened—no surprise there.

Yasuoka thrashed wildly.

“Wait! What are you doing!?”

“Don’t move. You’ll make me slip.”

“Stop—!”

He chose to quiet down, vaguely grasping her intent, though his bitter expression remained.

Snip… snip…

Soon, his pants and underwear were cut away in a circle around his crotch.

“…”

“So… what now?”

Both Karin and Yasuoka stared at his exposed genitals, perplexed.

“Not even hard, huh…”

“Of course not!”

His flaccid penis hung limply, as if disappointed by the situation.

No way to ask, What’s wrong, buddy? in this atmosphere.

For Yasuoka, getting aroused in this scenario was absurd.

He wasn’t into bondage.

“What? Wanna screw?”

“…”

Was he bluffing or probing her intentions? Yasuoka spoke boldly, a faint smirk on his face, his tone slightly mocking.

“Hey, say something, Karin.”

“…”

Karin glared at him sharply.

Her demeanor made it clear this wasn’t some planned kinky play.

“We started dating six months ago… How many times have you cheated?”

“Huh?”

To Yasuoka, it was a straightforward question.

Jealousy, as expected.

This elaborate stunt over that?

“Cheating’s no big deal—”

“Answer me!”

“…”

Her intensity made him drop the mocking attitude.

He judged himself at a disadvantage.

“I don’t keep count.”

“…As expected.”

Saying “as expected,” Karin fixed him with a cold, hollow stare.

“…Why do you cheat?”

“Huh? Why—?”

Yasuoka had never explained his reasons for cheating to anyone.

“Why ask now?”

She’d never questioned him before.

She’d silently tolerated it.

“You never cared before.”

“I always cared!!”

“…”

She hadn’t ignored his cheating—she’d noticed every time.

Now, she confessed how much it hurt her.

“Then why did you—?”

He started to ask why she’d overlooked it, but—

“Because I believed in you!!”

“Huh…?”

Karin cut in instantly.

She believed.

Not that she was tolerant.

She’d patiently waited for him to tire of playing around and commit to her.

“You weren’t like this before…!”

“What do you know about me?”

Karin had her grievances, but Yasuoka had his own—resentment at being restrained, at her complaints.

“You got cocky once you got popular in middle school! You weren’t like that before…!”

“What do you know about—”

“Because we’re childhood friends!”

“…What?”

“I know things because we’re childhood friends…!”

“Huh…?”

A bold “childhood friend” declaration, from their long-standing bond since elementary school.

They’d rarely called each other that.

To Yasuoka, Karin was just another woman, not special.

She seemed… different today.

Something had changed, unlike before.

Why? He wondered unconsciously.

Perhaps she’d “shed a layer,” but Yasuoka, uninterested in her, didn’t notice.

“You were… you were supposed to be—”

“So, the handcuffs?”

“I knew you’d hate it, but…”

“Idiot. Undo them.”

“Who’s the idiot?”

“You are, using damn handcuffs…”

“If you hate them—”

Seeing his reaction, Karin showed a hint of relenting, and Yasuoka inwardly cheered, thinking things might go his way.

“…Are you sorry?”

“I am. No more cheating. Undo them.”

“…”

His words dripped with insincerity, but Karin stared into his eyes.

“…Really, no more cheating?”

“I said no.”

“Then—”

Karin stepped forward, burying her face in his crotch.

“Ngh—”

“Whoa!”

She took his soft penis in her mouth, and he let out a short cry.

Slurp, slurp, slurp—her fellatio continued.

Naturally, his penis hardened.

They were used to this exchange.

“Phew…”

Satisfied, Karin wiped her mouth.

But it wasn’t over.

Yasuoka hadn’t climaxed.

“Takuya…”

Standing, she straddled his knees, squatting bow-legged and lowering her hips.

Slowly descending.

“Wait. You’re gonna do it like this?”

“…”

Sensing something off, Yasuoka tried to stop her, but Karin answered with silence.

He was restrained, unable to move. His pants were cut open, exposing only his now-erect penis.

“Takuya…”

“Hey, Karin.”

Aiming for his bare penis, she pulled her panties aside, exposing her vagina, bringing it closer.

No sign of stopping.

No bluff or threat. This wasn’t a joke.

A bead of sweat ran down Yasuoka’s neck at her unhinged demeanor.

He should stop this. Reason screamed it.

“Hey, wait. No condom!”

“Don’t need it.”

“What…?”

No condom needed.

A line he’d never heard from any woman.

Another bead of sweat trickled down.

“What’s your angle…?”

Trying to gauge her intent, as if negotiating, he asked.

“…If I get pregnant, you’ll change, right?”

“What?!?!”

Yasuoka was floored.

The worst possibility became reality—her deranged declaration threw him into a panic.

“Pregnant!? Wait, what are you saying!?”

“I can’t stand your cheating anymore…”

Her hollow eyes seemed to see something beyond his own.

“What!? Hey, you idiot! One dumb chick like Mana is enough!”

“Who’s that?”

“You know her, the Library Committee girl!!”

In utter chaos, Yasuoka blurted out his fling’s name, desperate to stop her.

Of course, it had no effect.

“Cheating’s the worst. I’m definitely getting pregnant with your kid.”

“What!? Are you insane!? Stop, seriously…!”

“Who’s insane?”

“You are!”

His attempts to buy time by arguing failed.

He glimpsed pubic hair through her shifted panties.

His penis’ tip disappeared into her.

Slurp…

Her vaginal entrance.

Her membranes parted as his penis entered.

“Ngh…♡ It’s… in…!”

“Damn…! Seriously…!?”

Unable to contain their arousal, they moaned.

In some unknown abandoned factory.

Evening had turned to night.

“Tak…uya…♡”

“Karin…! You’re really…!”

“Haha…♡ Hahaha…♡”

Like a female devouring a male, an endless night began.
