Chapter 94: The True Monster’s Name (3)

The squelch, squelch, squelch of flesh against flesh, mingled with wet, watery sounds.

Something moved atop his hips, bringing intermittent pressure.

In a haze of consciousness, Takuya Yasuoka awoke.

“Nn…”

The dim bulb on the ceiling still cast its feeble light.

Yet, compared to before he slept, the scene was slightly clearer, bathed in a faint morning glow despite the dimness, giving an oddly comforting feeling.

In truth, it was already morning—

“Ah… sa…”

Sensing the passage of time, Yasuoka confirmed in the darkness that the chains binding his legs to the wall and the handcuffs restraining his hands remained.

Exhausted and disheartened, he realized his restraints weren’t being removed.

“Ah…♡ Ah…♡ Ha…♡ Ah…♡ Nn…♡—”

A presence straddled him, grinding against his penis with her vaginal walls, intent on wringing out his semen.

“Karin… w-water…”

“Nnu…♡ …Gulp.”

When Yasuoka croaked for water, Karin halted her relentless movements, grabbed the nearby 2L plastic bottle, and took a mouthful. Then, mouth-to-mouth, she passed it to him.

Now completely naked—somehow, unnoticed—they pressed their bodies tightly together, skin sticking to skin, drawing water from each other’s throats.

In the decadent, depraved atmosphere, such intimate contact felt natural tonight—or rather, this morning.

“…Gasp.”

“Pha…♡”

After hydrating, Karin resumed her hip movements.

“Let’s… rest—”

“Haha…♡ Nn…♡ Ahh…♡”

Yasuoka’s weak plea for a break went unheard as Karin continued.

…This unprecedented act was undeniably changing them.

Their relationship, their psyche, their logic—everything internal was shifting.

Something already within them.

Recently touched by something—or someone—not present here, had undeniably altered them.

“Karin… air… oxygen…”

“Nn…♡ Ahh…♡ Ah…♡ Ah…♡—”

…The room reeked, sour and stale.

Unsurprising after a night of relentless intercourse.

Yasuoka didn’t feel a lack of oxygen or rising carbon dioxide but a suffocating sense from their mingled odors. The space, likely an abandoned factory, wasn’t sealed enough to hinder breathing.

Yelling for help was pointless, so Yasuoka resigned himself to being a vending machine, dispensing semen.

Karin, too, was like a machine, relentlessly pounding her hips—slap, slap.

“Ngh…”

Against his will, despite physical and mental exhaustion, Yasuoka felt his penis swell.

(…Again.)

Again, he thought.

He’d felt this each time they hydrated.

It was certain now.

The 2L bottle, filled with what looked like clear water, likely contained some drug.

Whether Karin knew or not, each time she fed him water mouth-to-mouth, his penis grew harder. In his foggy mind, Yasuoka was sure of it.

“Nn…♡ Ah…♡ Takuya…♡ Ahh…♡ Takuya…♡—”

“Ah…”

His voice, like a sigh or a mumble, betrayed his despair.

Karin sat atop him, facing him, slamming her hips up and down.

In this face-to-face position, how many times had she milked his semen?

When would this—exploitation—end?

“Takuya…♡ Love you…♡ Ahh…♡ Takuya…♡ Let it out…♡ Let out a ton…♡—”

“…”

He lacked the energy to resist or even jest.

In his hazy vision, the ceiling’s bulb softly outlined the girl’s silhouette.

Her form bounced, milking his semen, as he watched detachedly.

Her long black hair swayed wildly.

At their joined parts, squelch, squelch, slurp, slurp sounds rang out. Their mixed semen and fluids frothed white, like meringue or fine cotton, staining even her black pubic hair. Each separation drew sticky threads, evidence of their repeated acts.

“Takuya…♡ Takuya…♡ Takuya…♡ Takuya…♡—”

“Karin…”

Her fervent calls, seeking him single-mindedly, drew mumbled responses from him.

Another ejaculation neared.

He’d lost count, but a tingling in his hips signaled an approaching climax.

“…Ah…♡”

Somehow sensing it, Karin’s hollow eyes glinted mischievously, a playful smile forming.

“You’re gonna come…♡ Gonna shoot…♡ It’s okay…♡ Shoot…♡ Fill me up…♡”

“Kh—!”

His flickering vision, the heat in his hips, the semen surging through his urethra.

Unprecedented pleasure overwhelmed Yasuoka.

“I’m coming—!”
