Today, I’m going on a train date with my girlfriend.
But just a normal date… wouldn’t be much fun.
This was the entrance of my home.
I told Elina to show me her body.
“I-I know you’ll just force me to show you anyway…”
Elina’s voice trembled as she spoke, her face turning bright red as she hesitantly lifted the hem of her shirt.
Her pale skin glowed softly in the morning sunlight.
Her belly, empty from the mild laxative I’d given her, was slightly sunken.
Noticing the lustful look in my eyes, her large blue eyes glared sharply at me.
Around her waist was a pink pouch.
Inside, I’d hidden a small air pump device.
With a tap on my smartphone app, I could activate it anytime.
“It’s normal in Japan, you know? You’ve seen those women at train stations with big bellies, right?”
Even with such a ridiculous explanation, Elina hesitantly accepted and agreed to wear it.
Today, we were going on a train date—with the device still attached.
We headed straight for the station.
We took our seats facing each other on the express train.
Beep!
“Ugh…”
Elina let out a faint moan and pulled her knees together.
Her body trembled slightly.
Her large blue eyes stared out the window, trying hard to appear calm.
Gurgle—GROOOWL!
A loud noise rumbled from her stomach.
She glanced around nervously, checking if anyone had heard.
A few moments later, she started rubbing her stomach with one hand.
It looked like the discomfort was getting worse—she clenched her teeth.
“St-stop it…”
Gripping her belly over her clothes, Elina hunched forward.
Her slim figure was already starting to swell.
But women’s clothes are designed so cleverly—it barely showed from the outside.
“Haah… haah… hff…”
Her breathing grew shallow and fast, her shoulders rising with each quickened breath.
Her cheeks were flushed, and sweat was beginning to bead on her forehead.
Goro… gorororo… GYURURURURU!!!
An impossible sound rumbled from Elina’s stomach.
Several nearby passengers looked around, puzzled, clearly having heard it too.
“Guh… uuugh… agh…!”
Elina let out a strained moan, clutching her shirt tightly.
Her face was twisted in pain, her expression clearly breaking down.
This is bad.
Her reactions were getting more intense—she could barely hold back her voice anymore.
At this rate, it was only a matter of time before the other passengers noticed something was wrong.
Grrrgle… gllllrrrgle…!
Another deep, unnatural noise erupted from Elina’s belly.
Instinctively, I reached out, trying to quiet it.
But when my hand touched her, I froze.
Her stomach had expanded far beyond what I expected.
It was hard to believe this was the same slender body I had seen that morning.
It had been so flat and delicate.
She looked almost like a pregnant woman.
Panicking, I pulled out my phone and tapped the app’s stop button.
Nothing happened.
Trying to stay calm, I relaunched the app and tapped the screen again with my sweaty fingers.
Still no response.
No way…!
I had no choice but to restart my phone.
Even as I waited for it to boot up, air continued to inflate Elina’s stomach.
“Ugh… ga… ah…!”
Elina let out a choked cry, drawing the attention of nearby passengers.
Her belly… if this keeps going…
Panicking, I reached out toward her abdomen.
Snap!
A sharp sound pierced the air.
The button on Elina’s blouse popped off.
Through the opening of her shirt, I could glimpse her belly, swollen tight with air and pale as porcelain.
The skin had stretched so thin it looked almost fragile, drawn taut like the surface of a balloon.
Her breath came in shallow gasps, and now and then, a whimper slipped from her lips.
“P-please… st-stop it… hhic…”
She grabbed my arm with desperate force, her eyes twisted in a pain I had never seen on her face before.
I reopened the app over and over again, but the air pump wouldn’t stop.
Gurgle. Blorp. Groooan.
A deep noise erupted as Elina twisted her body sharply.
Her stomach, teased and stretched by the air inside, swelled even further from within.
“Aaah… nghh… aah…!”
Elina let out a guttural cry, tongue lolling from her mouth like a wounded animal.
I quickly reached out and covered her mouth, trying to muffle the sound.
A few passengers around us turned with concerned looks.
She couldn’t take any more of this.”The next stop is [Station Name]. Passengers getting off, please prepare.”
Luckily, the train came to a stop at the station just in time.
From the platform, I spotted a hotel nearby.
There was no other choice — we had to get out of here.
I tried calling out to Elina, but she only let out a pained moan and shook her head weakly.
Biting her lip, she clutched her swollen belly with trembling arms, her whole body quivering.
I scooped her up in my arms and made a dash for the hotel.
