Kaito's body didn't feel like his own anymore.
He woke up every morning with dried cum on his chest, thighs soaked, cock twitching in the air. Sometimes he remembered the sex. Sometimes he didn't.
But the ache in his balls never left.
They were always full. Always leaking. Always claimed.
His cock didn't respond to porn anymore. Or human touch.
It only twitched for them.

That night, the tunnel called louder than ever.
His car felt like it drove itself.
As the tires rolled onto the wet pavement, fog flooded the seats.
He stepped out on foot, drawn deeper inside.
What waited for him wasn't darkness.
It was a shrine—an ancient stone altar bathed in red lantern light, hidden in a crack of the tunnel wall he swore wasn't there before.
Three girls stood naked before it.
Reika, Ami, and Yuka.
All glowing. All wet. All moaning softly in unison.
---
Reika stepped forward, her pussy already glistening, her stomach slightly rounded.
"Onii-san… you've been cumming inside us so much… our wombs are starting to remember."
She ran her hands down her belly, biting her lip.
"If you keep filling me, I might start growing something."
---
Ami dropped to her knees, skirt gone, her uniform blouse half open.
Her pussy was dripping down her thighs, and she stared at his twitching cock with dead, horny eyes.
"I want to get pregnant too… even if I'm a ghost. Let me make a baby with your cum, onii-san…"
---
Yuka floated beside the altar, her disembodied head now attached to a full body—finally. Her legs spread in the air, her mouth still smirking.
"I'll drink your seed until it swims into my soul~"
---
Kaito couldn't even speak.
His cock was hard the moment they appeared.
It throbbed like it knew this was the night.
They pulled him to the altar.
He lay back, his shaft standing tall like a sacred offering.
---
Reika climbed onto him first.
No teasing.
No warm-up.
She lined up her pussy and slammed down, impaling herself to the base with a long, shaking moan.
"AHHHHhhh—!!! I can feel it! It's so warm~!"
She started riding hard—slap slap slap—her belly jiggling slightly with each thrust.
"Breed me, onii-san! Breed my ghost womb! Let it remember!"
Kaito grabbed her hips, fucking up into her desperately.
His balls ached. His mind buzzed. Her pussy sucked him in like a vacuum.
---
Then Ami climbed onto his face.
She straddled his mouth and lowered her soaked folds down, moaning as his tongue slipped inside her.
"Make me cum like that night~ Let my womb open for you too…"
She rocked her hips slowly, feeding him her ghost nectar, thighs clenching around his face.
---
Yuka hovered above his cock while Reika rode.
As soon as he looked at her, she bent down and licked Reika's stretched pussy, drinking the cum that leaked out mid-fuck.
"Mmmn~ you taste like a dad already, Kaito-kun~"
---
Reika's moans grew louder.
"I-I'm gonna—AHHH—I'm gonna take it—!! Cum in me! Fill it again!"
Kaito's balls clenched. His cock throbbed.
And with a roar—
He erupted.
---
Spurt after spurt of hot seed blasted into Reika's womb, her eyes rolling back as her belly twitched.
"YAMETE—IT'S TOO HOT—!!"
She collapsed onto his chest, trembling.
Cum dripped from her pussy.
Ami gasped and grinded harder against his tongue—
SPLASH.
She came too—legs shaking, thighs soaked.
Yuka moaned as she lapped up the mess.
---
But it wasn't over.
---
Suddenly, glowing red strings of spiritual light coiled around Kaito's cock, balls, and chest.
They lifted him into the air—Reika still impaled on his shaft.
A voice echoed through the tunnel:
> "The Womb Binding Pact has begun."
The girls moaned in unison.
Their bellies glowed. Their wombs flashed red.
Reika leaned up and kissed him, tongue deep.
"You're ours now… cum won't ever leave your balls without us~"
