Reposting one of my old stories.

A dimly lit room.
Moonlight filters through a gap in the curtains.
Hiss, hiss, hiss.
“Nnh!! Nguuuu!!”

Her name is Akari.
A student at ○○ Vocational School.
Creak!! Creak-creak!!!
As I stroke her soft, squishy belly, the bed creaks beneath her.

I climbed in through the window.
While she slept, I bound Akari’s limbs with rope and secured her to the bed.
An air pump—brought along for the occasion.
A tube extends from the pump, inserted into her rear.
Hiss, hiss, hiss.
“Guhh… nnh!!”
Her hair clings to her sweat-drenched forehead.
Just a few pumps and her sides begin to bulge, her belly spreading outward.
It seems her large intestine is inflating like a balloon inside her.

Gurgle-glurrrrr!!!
I press her belly through her T-shirt, and a loud sound erupts.
The bulging in her sides subsides, and her navel starts to push outward instead.
It seems the ileocecal valve has opened, letting the air in her large intestine rush into her small intestine all at once.
Hiss, hiss, hiss.
“Uuunh! Guh-nnh!!”
Cries mixed with fear and exhaustion echo through the room.
Tonight, only two people are in this house—me and Akari.
Hiss, hiss, hiss.
“Ugoh… gobuh!! cough, cough!!”

Vomit seeps out from the edges of her gag.
Akari’s body convulses on the bed as she coughs violently.
It seems she’d been eating sweets earlier tonight.
I gently wipe her stained, pretty face clean.
Hiss, hiss, hiss.
“Ugoohh!! Ogoohh!!”
She arches her back like a bow, thrusting her belly forward.
