A Secret Invitation
"Holy shit, we got it! Hell yeah, nice work!"
Jinwoo clapped his hands, buzzing with excitement.
"Haa... haa..."
Ayoung collapsed into the chair, gasping as if she might fall apart at any second.
Before proceeding to the third sector, there is an additional mission in the wall drawer.
A dry, mechanical voice filled the room.
Jinwoo hurried over and yanked open the small drawer set into the wall.
"Huh? Yo, Ayoung. There's something in here that looks like a wireless vibrating egg?"
"W-what is that... nngh..."
The female player will insert the wireless vibrating device deep into her own pussy.
"Y-you're insane...! I absolutely cannot do that...!"
Ayoung shook her head hard, face drained white as she stumbled backward. The gas had set her body burning hot, but a scrap of shame still clung to her reason by its fingernails.
"Hey, Ayoung. What's wrong?"
"Even so... how am I supposed to shove that into my own pussy... I thought I was going to die of humiliation just a minute ago... it's too embarrassing..."
Tears welled in her eyes as she clenched fistfuls of her skirt.
"Babe. We came here knowing this was an adults-only hardcore escape room. You should've been ready for at least this much."
Jinwoo frowned and stepped closer, coaxing her. He pressed his lips right against her ear and whispered, low and private.
"I'm going crazy watching you like this right in front of me. But I'm holding it in, aren't I?"
"O-oppa..."
"It's a mission, so just close your eyes and put it in. When the three hours are up and we get home, I'll fuck you raw on the bed until you're screaming. Okay?"
The whisper of her boyfriend claiming he was a man too, holding back his own need—those filthy words made Ayoung's heat-soaked, gas-marinated body burn even hotter, already starting to crave pleasure.
"Hngh... damn it, because of you, oppa... haa..."
In the end, tears dripping steadily down her cheeks, Ayoung hiked up her skirt with trembling hands. She pulled her panties aside herself and pushed the vibrating device into the slick, flushed entrance of her pussy, already soaked with her own juices.
"Nngh... haah... it's in..."
Jinwoo looked straight up at the ceiling camera and shouted.
"Master! It's all the way in! Open the next room already!"
In the Control Room, I curled the corner of my mouth and turned the power dial on the remote just a little.
Vrrr—
"Aah...! Hn!"
The third sector is now open. The 140-minute countdown resumes.
The moment the vibration started, the last fraying thread of reason still clinging to Ayoung's brain snapped clean. From here on, for every remaining minute, she would be nothing but a perfectly heat-struck bitch who had forgotten shame.
"Hey! Lee Ayoung! Get over here and look at this!"
"Haa... o-okay... nngh... every time I walk... my insides are shaking so hard..."
For the remaining 140 minutes, while Jinwoo tore through puzzles and locks like a man possessed, moving them from room to room, the device never stopped vibrating inside Ayoung's tight cunt.

"Oppa... I think I'm really gonna cum... haah! Can't we take this out a little...?"
"Just hold on a bit longer! I told you we'll do it properly at home! I just finished the calculation problem!"
Whenever Jinwoo got stuck on a puzzle, I quietly cranked the remote's output higher.
Vrrrrr—!
"Aaaah! Oppa... the inside of my pussy is so itchy... hn!"
"Hey! You gonna keep moaning like that? I can't concentrate!"
"But... ah! It keeps thrusting inside me... haah! Fuck me a little..."
Completely out of her mind, Ayoung simply sank to the floor and rubbed her thighs together, dripping slick all over herself.
And so a long 130 minutes crawled by under the torture of pure pleasure.
Time remaining — 00:10:00
"Whoa, this must be the last room! The scale is insane!"
When they reached the final sector, Jinwoo darted around in an excited frenzy. Ayoung was already fully conquered by pleasure, crawling across the floor and panting hard.
"Haa... haa..."
The panties that had been soaked by the juices she'd leaked around the vibrating toy clung wet and sticky to the insides of her thighs.
"Yo, Ayoung! Come look at this!"
"O-oppa... my legs won't hold me... nngh..."
"We're almost there! We've only got ten minutes left!"
Jinwoo grabbed her arm and hauled her in front of a massive glass tube. Inside the tube hung a golden key. And right in front of it sat a microphone.
This is the final escape mission.
My voice rolled through the sealed room over the speakers.
From this moment, the vibration of the device inside the female player's body will be raised to maximum.
"Haah...! Nngh!"
For the three minutes the device is active, you must not hold back your pleasure. Moan into the microphone as lewdly as you can.
Only if the decibel level exceeds the threshold for three full minutes will the final glass tube open.
The shame and hesitation she had shown in the earlier rooms were gone. Completely consumed by the gas, Ayoung was almost relieved—here was an excuse to finally let the bottled-up pleasure explode.
"Oppa... this, haah! Hurry... tell him to turn it on already...!"
"H-huh? Wait, are you actually okay with this?"
"Aaah! Hurry! My pussy is going crazy...!"
Ayoung seized the microphone herself and dropped to her knees. Without a shred of mercy, I twisted the remote dial all the way to the end.
Vrrrrrrr—!!
"Aaaaaah—!!!"
The device buried in her cunt went berserk, hammering her most sensitive spot without pause.
"Haah! Ah, oppa...! It's too strong... haah! My pussy's getting ruined...!"
"Hey! Louder! Scream into the mic louder! The decibel gauge is climbing!"
Even as his girlfriend sat on the floor getting her pussy pounded and pouring out heat-struck moans, Jinwoo only stared at the gauge on the glass tube.
"Haah! Ah, Ayoung's pussy... nngh, I'm going crazy...!"
Insufficient. Beg Master for pleasure more obscenely.
"Master...! Haah! Having a vibrator stuffed in my pussy feels so good...! Please ruin Ayoung's pussy more...!"
A perfect declaration of surrender, pickled in pure pleasure.
"Haa, haah! Aaaah—!!"
Before the three minutes were even up, Ayoung's body arched like a drawn bow. Clear juices gushed from her pussy in a fountain, soaking the special carpet on the floor.

Beep— clack!
The glass tube opened and the final key dropped free.
"Wooooh! It opened! Yo, Lee Ayoung! We cleared it!"
Time remaining — 00:04:12
Theme complete. Please exit through the door.
The heavy iron door swung open, and the two of them walked out into the lobby.
"Whoa, damn... boss. That last part was seriously intense."
"Congratulations. You escaped perfectly within 180 minutes."
I handed them two canned drinks with a blank expression. The gas effect began to dissipate the moment they stepped through the door and vanished right on the 180-minute mark. Right now Ayoung's mind was completely back to normal. But her legs still trembled, and the inside of her skirt was still sticky with the juices she had just squirted.
"Hey, later at home I'll take proper care of you. You know that, right?"
Jinwoo wrapped an arm around Ayoung's waist and whispered into her ear.
"...Huh? Oh, yeah."
Ayoung kept her head down, cheeks burning. Any normal woman, once her senses returned, would have burst into tears of shame and cursed me out or demanded answers. Instead she twisted her thighs together and stole a glance in my direction. It wasn't resentment. Her body—and the reason that had already crumbled—had accepted and refused to forget the overwhelming pleasure of those 180 minutes.
"Got any even crazier themes next time? Today was seriously next-level."
Jinwoo asked, still hyped. I set a prepared Black VIP Card on the table.
"Of course."
"Oh! We should book again next weekend."
I looked straight into Ayoung's wet eyes as I spoke.
"Next time the two of you can come together..."
"...?"
"Or the lady is welcome to come alone."
"Alone? How do you do an escape room alone?"
Jinwoo asked, puzzled.
"Our escape room has one-person ultra-secret themes. A perfect private course far deeper than what you experienced today—one that controls you down to the bone."
At my words, Ayoung's narrow shoulders gave a little jolt.
"If you come alone, you won't have to worry about anyone watching or force yourself through puzzles. You'll be guided to a special room where you can be faithful only to your own instincts."
"Whoa, one-person hardcore? Sick. Hey, Ayoung. Wanna try it alone? I'll watch from outside."
Jinwoo snickered, joking around—completely unable to imagine what kind of hell his woman would willingly walk into.
Ayoung swallowed hard without a word. In her head she was screaming that this was insane, but her trembling hand was already reaching for the black card on the table.
"Ah, boss. I'm gonna hit the bathroom real quick! Yo, Ayoung, wait a sec."
Still riding the high, Jinwoo bolted for the restroom. Only Ayoung and I were left in the lobby. Silence settled over the space. Avoiding my gaze, Ayoung carefully stretched her hand across the table. Her shaking fingers finally closed around the Black VIP Card and shoved it deep into her skirt pocket.
Card hidden, she fidgeted and parted her lips.
"Um... b-boss..."
Vrrr—
I gave the remote button in my pants pocket a short press.
"Hn...! Aah!"
Ayoung flinched hard and clamped her thighs together.
"Guest Ayoung. Your form of address is incorrect."
I stepped closer and whispered against her ear.
"Not 'boss.' You should call me Master."
"Haa... M-Master... please turn it off..."
"Don't force it out. It's a small gift from me for becoming such a perfect bitch today."
"A gift...?"
Vrrrr—
I nudged the output a little higher. Ayoung's legs nearly gave out; she braced herself on the counter and panted.
"Haah...! P-please... what if oppa comes back..."
"Next time, you will come alone."
I tapped the black VIP card clenched in her hand.
"That filthy pleasure you felt today while squirting behind your boyfriend's back—I'll keep it as a perfect secret only I know. You won't have to tell a soul."
"Haa... ah..."
"If you come alone, it won't be some little toy... I'll bury my real cock all the way into your pussy and take complete control of you."
Ayoung's pupils shook hard with pleasure and the thrill of betrayal.
Click—
"Whew, that hit the spot. Ayoung, let's go!"
Jinwoo came out of the bathroom. I casually switched the remote off and clasped my hands behind my back.
"Take care on your way home."
Ayoung twisted her legs together and bowed her head to me. The Black VIP Card was already clenched tight in her hand.
Before long, she would come knock on this door of her own free will—without Jinwoo ever knowing.
