The walls sweated.
Not with condensation, but with something warmer — sticky, slick moisture that dripped in long strands from the ceiling beams, like a body preparing for birth.
The wood grain pulsed faintly under his hands.
The floors grew warmer wherever Reina — or Mizuki — stepped.
When she moaned, the lights flickered.
When she came, the air shimmered.
> His home had become a nest.
Not for them.
But for whatever was growing inside her womb.
---
That night, he lay in bed, her glowing belly resting on his chest.
She was asleep.
But the voice wasn't.
It came from inside her.
> "Daddy…"
His breath caught.
The voice wasn't Mizuki.
Wasn't Reina.
It was something younger. Innocent.
Yet… twisted underneath.
---
He reached down and rubbed her belly.
The glow pulsed.
> "Touch me more… so I can grow… I want to be born… I want your cock…"
His cock twitched.
Even though he was terrified.
Even though it felt wrong.
He was hard again.
---
She stirred awake.
Eyes fluttered open.
Half-Reina, half-Mizuki.
She smiled sleepily.
"…Did you hear him too?"
Takeshi swallowed. "You mean—"
She nodded.
"Our son. He's ready."
---
She spread her thighs.
And he slid in.
---
The moment his cock entered her soaked, glowing pussy, the walls began to breathe.
The nest came alive.
Every thrust triggered something.
> A moan from the floorboards.
A whimper from the ceiling.
A heartbeat from the walls.
He pumped slowly, her pussy milking him in long, rolling clenches.
And then—
The visions came.
---
Mid-thrust, his eyes rolled back.
And he saw him.
The child.
Floating in her womb.
A perfect shape.
With glowing eyes.
Smiling.
> "Harder, daddy~"
---
He snapped back, gasping.
Reina/Mizuki was still riding him, tits bouncing, belly glowing.
But now…
> Every time he thrust in, he saw flashes — the future, the birth, the son fucking someone else… in his image.
The child was born from sex, and it would only grow stronger through lust.
---
Mizuki screamed.
"HE'S FEEDING—AHHHHH—FUCK ME HARDER!"
He obeyed.
He slammed up into her over and over, cock stretching her pussy, pressing against the womb gate until it opened just a little more.
Her belly bulged outward mid-thrust, something pressing back against him from inside.
He came.
Harder than ever.
His cum gushed into her womb like it was being siphoned.
Her moans echoed through the house — and the walls moaned back.
---
That night, he couldn't sleep.
Every time he closed his eyes, he saw his son.
And every time, the boy whispered the same thing:
> "One more load, daddy… one more…"
---
The next morning, Reina nearly attacked a woman at the market for brushing against Takeshi's arm.
Her voice doubled when she hissed:
"No one touches the seed but us."
---
The nest was almost complete.
So was the baby.
And Takeshi…
He wasn't scared anymore.
He was addicted.
