It was supposed to be just another late-night delivery.
Kaito Tachibana sighed, rolling down the window of his beat-up kei car as the summer humidity pressed against his skin like invisible hands. The air in the mountains outside Tokyo was thick, damp, and still. Crickets chirped lazily as he drove up the winding road toward Hachioji Tunnel—the infamous stretch locals whispered about.
"Ghosts, huh...?" he muttered, scratching his head.
The delivery job was simple. One package. One old woman. She lived just past the tunnel on the outskirts of a half-abandoned village. But no one ever wanted to drive through that tunnel at night.
And now he knew why.
The moment he turned into the tunnel, it felt like passing through a curtain of cold water.
Everything went silent.
The chirping stopped. The engine noise dulled. Even the rattling of the package in the back faded.
Kaito's hands tightened around the steering wheel.
"Hah… spooky as hell," he muttered, trying to lighten the mood. But then—
Whispers.
Soft. Feminine.
"Onii-san… aaah… nnn… don't stop…"
Kaito's heart jumped. He snapped his head toward the backseat. Empty.
He adjusted the rear-view mirror.
For a second—just a flicker—he saw a pale, naked woman sitting in the back, her legs spread wide, fingers dipping into her dripping pussy, eyes lidded with lust.
Then—gone.
He slammed the brakes.
"H-Holy shit…"
He wiped sweat from his brow. Was he hallucinating?
The tunnel wasn't long—barely two hundred meters—but tonight it stretched endlessly. And now, a heavy pressure settled in his pants.
His cock twitched, hardening fast.
"N-not now…" he groaned, squirming in his seat.
But it was throbbing. Veiny. Unbearably stiff.
He glanced around—nothing but darkness, no cars for miles, no cameras.
"…Just one quick one."
He parked the car in the middle of the tunnel. The low hum of the headlights cast eerie yellow light onto the damp, stained tunnel walls. Shadows danced.
His hand moved to his crotch.
He unzipped his jeans and pulled out his thick ochinchin, already leaking pre. It slapped against his stomach with a wet sound.
"Shit… why does it feel this intense…"
His fingers wrapped around the shaft and began stroking. Slow. Long pulls. His breath hitched.
But it wasn't just him.
Something was… helping.
Invisible fingers grazed his balls. Something warm and wet slid along his inner thigh.
His hips bucked.
"Wh-who's there?!"
No answer. Just the echo of soft moans—somewhere close. So close.
Kaito~...
Let me taste it…
Cum for me, onii-san… inside the tunnel…
His cock was twitching wildly now.
He couldn't stop. His hand was moving faster, guided by something unseen. He was being milked—slow, controlled, purposeful strokes.
"F-fuck—what is this—nghh—!"
His eyes widened as he felt wet lips close around his tip.
Nobody was there.
And yet… someone was sucking.
The pressure on his glans was unreal. A soft tongue swirled, licked, teased his piss slit.
His balls clenched.
"No… no, I'm gonna—!"
He tried to pull away—but he couldn't. His body locked. His hips thrust forward on their own.
"I'm cumming—!"
Thick, hot semen erupted from his cock, shooting in sticky spurts into empty space.
But it didn't fall.
It vanished—slurped up by invisible lips that moaned in delight.
"Ahhh… nnnn~ sugoi... so much~"
Kaito's vision blurred. His body trembled. The orgasm felt longer than any before—his dick pulsing again, again, again—emptied completely.
Then silence.
Just the sound of his panting breath.
He collapsed back against the seat, cock still twitching. A final drop of cum slid down his shaft.
His hands shook as he zipped himself up.
"What the hell was that…" he whispered.
He glanced in the rear-view mirror again.
A pair of soft, golden eyes stared back at him.
And a voice.
"See you tomorrow night, onii-san…"
He slammed the car into drive and sped out of the tunnel.
The moment his tires hit daylight, the pressure lifted.
The sun had already started rising.
He never made the delivery.
---
Later that morning, back in his apartment, Kaito awoke in a daze. He wasn't sure if it had all been a dream.
Until he looked down at his pants.
Soaked.
Not just his boxers. His sheets, the comforter, even the mattress beneath. It reeked of fresh semen.
He shivered.
Then his phone buzzed.
