Kaito didn't even try to live normally anymore.
His days blurred by in silence.
His nights belonged to the tunnel.
And his cock… belonged to the dead.
But not just any ghosts.
Breeding spirits.
They didn't want his soul.
They wanted his seed.
Over and over.
---
That night, the shrine inside the tunnel was glowing—pulsing red with lust.
Candles floated midair.
Mist swirled around the ancient altar.
And Reika stood above it, completely nude, her belly already round and swollen with spectral essence.
Her hand rubbed over the curve, fingers tracing glowing red glyphs that formed across her skin like tattoos.
She looked over her shoulder, eyes half-lidded.
"I ovulated today, onii-san… my womb's pulsing for you again~"
---
Kaito's cock responded immediately—throbbing to full hardness before he even stepped forward.
He didn't speak.
Just stripped.
Every article of clothing vanished with a thought.
The moment he approached the altar, Reika dropped into reverse cowgirl, her glowing belly bouncing slightly as she lowered herself onto his cock—
SPLOOSH—!
"AAAHHNNN~! It's twitching inside so fast… it knows it's time to breed again~"
---
She rode him fast from the start.
Her pussy was hotter than ever—tight, hungry, suctioning every inch like it was begging for another insemination.
Her hands wrapped around her swollen belly as she bounced.
"Look at this… this is what you did to me~ and now you're gonna do it again~!"
Squelch. Slap. Squelch. Slap.
Her moans echoed down the tunnel like sacred chants.
---
Then Ami appeared beside the altar, fully nude as well.
But instead of mounting, she lay down beside Kaito, curling his hand toward her belly.
Her voice was soft.
"Mine's not swollen yet… but I want it to be."
She lifted his hand and pressed it gently to her lower stomach.
"Talk to it… talk to our baby… maybe it'll grow faster~"
Kaito trembled as he rubbed her smooth skin, cock still buried in Reika's ghost-pussy.
He whispered, half-conscious, mind drowning in lust.
"C-can you hear me in there…? I'll fill you again tonight…"
Ami moaned, grinding her hips up into his fingers.
---
But then—Yuka descended from above.
Now with full form, her body hovered upside down in the air, floating like a demoness in heat.
Her legs opened over his face.
Her pussy dripped from above.
She grinned.
"You don't cum until we ovulate together, got it~?"
Then she lowered onto his mouth—face-sitting from above, smothering him in ghost nectar.
---
Kaito was now fully pinned.
Reika bouncing on his cock, belly gurgling
Ami moaning softly, rubbing his balls
Yuka riding his face in reverse air cowgirl
His body was stretched to the limit.
Every nerve burned.
---
Reika suddenly moaned louder—
"I-I feel it—! It's moving! It's coming again—!"
Her belly pulsed red, glyphs glowing brighter.
"NAKA NI DASU NOOOOWWW—!"
Kaito couldn't hold back.
His cock exploded inside her with a violent blast—
SPLURT—SPLURT—SPLURT—!
Endless ghost cum flooded Reika's womb, her belly bulging slightly bigger.
Ami screamed, cumming from just watching.
Yuka moaned above his mouth, climaxing with a spray of spectral girlcum into his face.
---
All three orgasmed at once.
And Kaito passed out.
---
When he woke, his cock was still twitching.
Still inside Reika's leaking pussy.
And the altar whispered:
> "The pact deepens. One more climax, and the Tunnel Goddess will awaken…"
