Doing It As Promised?

Squelch! Squelch-squish![Pew-pew-pew, boom! Ally defeated!]

The smartphone speaker blared with deafening game noises, threatening to shatter the air.

In the cramped bathroom stall filled with that racket, I sat perched on the toilet lid, desperately fingering between my legs.

"Ngh...! Mm, uungh...!"

Right outside my stall door stood Ye-eun Seo.

Just one thin door separating us in this precarious secret masturbation session.

No matter how loud the game was, if even a hint of sound leaked out, I'd be screwed. I clamped a handkerchief in my mouth ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to stifle my moans.

- Squelch! Squish, squelch!

"Hngh...! Hoo, uh.... Mmph...♥"

I pulled out the rotor that had been stuffing my pussy and pressed it hard against my most sensitive little bean with one hand.

Then I shoved two slick-with-juices fingers into my empty hole and pistoned them like mad.

Quick, gotta finish fast...!

My heart pounded, every hair on my body standing on end.

I'd made the excuse of having a big dump, but staying in here over ten minutes would definitely raise suspicions from those two outside.

In this race against time, desperate to calm my raging heat, I moved my fingers way rougher than usual.

- Squish, squelch... Squelch!

"Unh! Mmph...! Haaang... Hn!"

Just a bit more... almost there...!

Was it the urgency to finish quick, mixed with the thrill of sneaking this off from those two?

My body heated up faster than ever before.

I'm close, I can cum.

Feeling that dull burn building in my lower belly, I slammed my fingers even harder to push toward climax.

- Squelch, squelch, squiiiish... Squish!

"Ngh...!! Mm, bmmph...! Hnnnngh—!!"

Here it comes. The response is building.

Biting down hard on the handkerchief in my mouth, my hips shuddered violently.

My thighs twitched in spasms, the tender walls inside my pussy clamping and quivering around my fingers.

I'm cumming, cumming from secret masturbation...!

"Hooooh!!"

What hit me was a short, light orgasm.

A gentle shiver rippled through my whole ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠body, fireworks of sharp pleasure exploding in my brain.

It was nowhere near as intense as Ye-eun's fingers, but still, not bad on my own.

"Haa... haa... pffhaah...."

As the afterglow faded, I spat out the soaked handkerchief.

The fiery blaze in my lower belly that had felt ready to drive me insane had died down somewhat.

But in its place came a crushing emptiness and dissatisfaction.

Just two fingers and the rotor's weak vibes were nowhere close to yesterday's destructive climax.

No gushing squirt, no overwhelming whiteout of my vision.

What ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I'd done was just a pathetic, miserable wank to barely scratch the unbearable itch.

Still... I put out the immediate fire. This'll do... yeah.

I comforted myself like that, hastily grabbing tissue to wipe between my legs.

Then I shoved the rotor back into my still-slick pussy.

The foreign intrusion made my body tremble again, but to fake following the game rules, I had no choice.

I straightened my uniform skirt, smoothed my messy hair, flushed the toilet, and stepped out casually.

"Oh, all done, Seo-jin?" "Y-yeah.... My stomach hurt, so I guess I sat longer than usual."

Ye-eun, who was checking herself in the mirror at the sink, turned to me with a smile.

Her reaction confirmed no sounds had leaked out.

I let out a sigh of relief and headed to the sink.

I'd wiped with tissue, but with all that juice, I wanted to rinse with water.

Plus, it looked natural after a "big one."

"Ugh, poop-girl. You finish your business?" "Wh-what the hell, you psycho. Don't you ever shit?" "Not for that long, I don't. Let's grab food already, I'm starving."

Just then, Hye-won Kang walked in, wrinkling her nose and waving her hand.

I splashed water from my hands at her in retort.

Hye-won, nice assist.

I got labeled a shitter, but it hid the fact I was a pervert jilling off to a game stream in the bathroom.

Now I just had to play it cool and head to eat.

As I relaxed a bit and moved to leave, Ye-eun grabbed my arm.

"But Seo-jin."

"Yeah...?"

"What was all that racket in the bathroom? Explosions and chaos."

Her eyes locked on mine, and guilt made me flinch.

Calm down, Lee Seo-jin. You prepared for this.

I played it cool and rattled off my prepped excuse.

"Oh, that? It's a game ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠stream I watch a lot.... For big dumps, in case any sounds embarrass me, I just play it loud."

"Aha, gotcha~. Getting shy about that stuff? You're such a proper girl now, Seo-jin."

"Yeah.... Sorry the sound was loud anyway."

"No worries, happens~. So, wanna show us what you were doing?"

It was a perfectly reasonable cover, even to me.

But Ye-eun looked skeptical, her eyes demanding proof.

A bit guilty, but to prove my "innocence," I pulled out my smartphone confidently to show the watch history.

"Don't believe me? Look. It's really a game stream."

"Hmm~. I see. But y'know..."

But as I held out the screen, Ye-eun lightly pushed my hand away.

Instead, her pale hand darted toward my uniform shirt pocket and slipped right in.

"I'm way more curious about this~."

"Wha...?"

What she pulled out was a tiny recorder.

That's when I remembered the mic pinned to my collar.

Right—to monitor what happened around me, they'd stuck a mic on my clothes.

Goosebumps exploded across my skin, but I forced my racing heart to calm.

It's fine. I pressed the speaker right against the door at max volume.

I swallowed hard, reassuring myself.

Handkerchief in mouth, stall full of blaring game noise.

No way a tiny mic on my collar cut through that to catch my muffled moans.

"Go ahead, listen. It'll just be game sounds anyway."

I tilted my chin defiantly, going all-in.

But Ye-eun's leisurely smile didn't fade.

If anything, she narrowed her eyes like it was amusing.

"Seo-jin, you really don't know how advanced tech is these days, huh?"

"Huh...?"

"Know what comes standard on high-end recorders now? Noise cancellation."

"Noise cancellation?"

"Yup. Link it to your phone like this, and it wipes out loud background noise or machine sounds, leaving just the important stuff."

"Wh-what?!"

Her silky explanation pierced my ears.

My heart didn't just sink—it plummeted through the floor into endless freefall.

No way, tech like that doesn't exist.

As I panicked, Ye-eun held the recorder from my pocket next to her phone.

"Here, Hye-won. Wanna listen together?"

"Ooh, what is it?"

Hye-won crowded in curiously, and Ye-eun unhesitatingly pressed play.

- Ding

I squeezed my eyes shut.

Please, just the game. Please.

But cutting-edge tech crushed my desperate prayer.

The game sounds that had screamed from the speakers were now a faint, muffled background hum, like from the next room over.

Instead, crystal clear on the recording: my moans, muffled as if something was stuffed in my mouth.

What the—why is this happening?

Why is it just my sounds?!

"Hic?!"

And it wasn't just moans.

The lewd, explicit squelching of my fingers plunging into my sopping pussy was captured with chilling clarity.

Finally, the quivering spasms at climax and my ragged gasps as I spat out the handkerchief—all of it poured out.

Ye-eun stopped playback and closed her eyes.

I'm fucked.

Properly, totally fucked.

Not just moans piercing the game noise, but even the squelching too...!

"Oh my, the sounds are killer. Our little Seo-jin got super turned on sneaking a wank under game cover, huh?"

"N-no...! That's not my voice...!"

"That squelching midway? Not a dildo—sounds like two fingers ramming in. And the final shudders? Light orgasm for sure. Right, Hye-won?"

"Yeah, total squirter sounds. Epic."

"S-stop...! Please, stop...!"

Their public critique broke me—I burst into tears from the humiliation.

I lunged for the recorder in Ye-eun's hand, but she sidestepped easily with a grin.

"What's wrong, Seo-jin? You said it wasn't you?"

"Hic... uuh...."

"Oh, so it is you, huh?"

No more excuses.

My voice, my pussy sounds—too raw, too unmistakable for any "glitch" bullshit.

I hung my head, trembling, forced to admit it.

"...Y-yeah.... I... I did it...."

"Hmm~. Really now?"

Hearing my mosquito-sized surrender, Ye-eun sauntered close and lifted my chin.

Her eyes gleamed cold and sharp.

"Lying to your friends about 'business,' then hiding in the bathroom for secret masturbation."

"Hnnngh...."

"Is that what you call normal academy life, Seo-jin?"

Her icy facts hit like violence; I shut my eyes.

Of course not.

Anyone could see "business" as cover for jilling was far from normal.

As I stayed silent, Ye-eun smiled and stroked my cheek.

"So our Seo-jin... lost the game?"

"Th-that's..."

"What happens when you lose?"

I trembled, meeting Ye-eun's gaze.

Her mouth smiled, but her eyes warned: say nothing, and this goes south.

A glance aside showed only Hye-won, glaring in contempt.

Ah, it's over.

Alternating looks between them, I sensed total loss of control.

Finally, with quivering lips, I gave the delinquent girls what they wanted.

"N-next experience... h-has to be... as a p-pet...."

"Right? So we'll do it as promised?"

"Y-yeah...."

"Perfect—tomorrow's our day off, so starting then."

"Hnnngh...!"

"Get your mind ready, Seo-jin~."

Staring at Ye-eun's smiling face, I nodded meekly.

I hate this....

I wish tomorrow never came.
