The Noona Who Came
3:20 a.m. Room 301.
It was the first time I'd ever set foot in her room. The layout was more or less the same as mine — foam roller, dumbbells, and a place roughly a hundred times cleaner than anything I lived in. The only other difference was how thick the diffuser smelled.
I had a pretty good idea why.

"Haah. I seriously want to die. What even is any of this."
Seoyeon stood in front of the full-length mirror, palms dragging down her thighs, face crumpled like she might cry. She was wearing the white uniform leggings the center director had ordered her to show up in.
They were thin. Stupidly thin. Thin enough that the pale of her skin glowed through the cloth. The carved sweep of thighs built by years of training, the round lift of her ass — there wasn't a single thing those leggings could hide.
I've actually lost it. I'm standing in this noona's apartment.
Phone in hand, I stood behind her and swallowed hard. From the back, even the faint line of her underwear showed through.
That wasn't the real problem.
"Hnnngh— damn it, again."
She clutched her stomach and folded at the waist.
An hour had passed since she'd drunk the bowel prep cleanser. In that time she'd been in and out of the bathroom four times, and every time I'd retreated toward the entryway with my ears covered. Before she even shut the door she'd made me swear it three times: cover your ears.
The bathroom runs had finally slowed. What was left inside her was the problem. The cleanser had turned her guts inside out, and the gas that couldn't get out had lodged itself everywhere.
Ding.
Her phone went off with perfect timing.
"Are you actually insane?! Middle of the night and he wants pictures — that shriveled old bastard doesn't even get blood in his dick!"
She stamped her feet and unloaded.
She still had to send them. If she wanted to survive at the center.
"Minchul, hurry up and shoot! I can't even breathe!"
"Noona, your stomach's sticking out way too much. They're gonna nitpick and say you've got flab."
"It's fine. I'll suck my gut in hard. You just hammer the shutter. Got it?"
She squeezed her eyes shut and clenched her fists. Then she hauled that swollen belly inward with everything she had.
"Hup—!"
Her stomach caved until the ribs showed. The problem was that whatever she forced down from above had nowhere to go but lower.
"Hnnnngh—!!"
From the side I could see her ass trembling in the white leggings, clenched so tight it looked ready to split the seams.
"Noona, I think you're gonna burst."
"Don't make me talk, you little shit! Just hit the button! Hah—? It's coming!"
Tears stood in her eyes while she ground her teeth. The tough older sister who used to smack people across the back out in the neighborhood was gone; she was pouting like a kid about to get a shot. Weirdly, it was cute.
Click. Click. Click.
The front shots were salvaged somehow. What was left was the rear view the director had specifically demanded.
The second she turned, bent at the waist, and pushed her ass back, the balance she'd barely been holding collapsed.
"Ah."
And from the white leggings, at last, that sound.
Pssssss... peeee—eek!
A thin, pitiful leak forcing itself through a gap no bigger than a needle's eye. Like a draft whistling through a window crack at midnight. Like someone wailing from far away.
A Ghost Fart, in other words.
"No— stop, please!!"
She clapped both hands over her ass. Useless. Once the gap opened, it refused to close.
Shhhhhk... pyooooong♥
The studio was so quiet the small sound filled the whole room. A moment later, warm air touched the tip of my nose.
It didn't smell like last time. Maybe because the cleanser had already flushed her once — the sulfur was much fainter, and in its place was something sweet and fermented, almost like sikhye, that milky rice drink.
So this is noona's clean taste...
But something about her was wrong.
She should have been covering her face and collapsing the way she always did. Instead she braced a hand on the wall and let out a strange moan.
"Haa... nnh. What the hell. Something's weird."
Her voice was wet.
Thinking about it, maybe it made sense. For more than ten years all she'd ever done was hold it. And now? She'd blown something out at the absolute limit. She'd probably never once let it leave her this slowly.
"My stomach feels wrong. It keeps tingling. Hah—?!"
Her toes curled.
Pfft.
The instant the last of it slipped out, she shook all over. Her hand slid down the wall, and she sank with it.
"Haa. Minchul."
Half-unfocused, she looked up at me. In those wet eyes, confusion and fear were tangled with a pleasure she couldn't deny.
"Why is my body doing this?"
I couldn't answer.
She was someone who'd lived her whole life as a fitness trainer, proud of controlling every muscle in her body and every gram of her diet down to the line. I turned it over carefully — the possibility that a woman like that had just climaxed in front of a primal need to void that had slipped completely out of her control.
Still on the floor, she stared down between her own knees. She closed her thighs and opened them again, as if checking something, and her face burned all the way to her ears.
"This isn't that."
"Huh?"
"This happens sometimes when you work out. You brace your core and it's just... like this. It's a muscle thing."
I hadn't even asked, and she was already explaining herself. Coming out of a trainer's mouth, it sounded way too suspicious.
"Noona."
I went to my knees and eased in until I was right in front of her. Close enough that my breath touched her flushed cheek.
"Your body's being honest. Ten years of holding it, nerves wound that tight, and then all that pressure dumps out through a narrow opening at once... so your brain got confused. No. Not confused. Your body actually felt good."
"D-don't lie! Are you crazy? Why would I— from something that dirty... nnh!"
"It's not a bad thing, is it? If something that only ever hurt finally felt okay, just this once."
"Shut up. That's enough."
She pushed at my chest. Not so much a push as setting her palm there. Then her hand crumpled a fistful of my T-shirt.
Right then her stomach made another sound.
Grrrrrgle... gurgle.
What had happened before was the opening act. This was every pocket of trapped gas surging in at once.
"Aaaah! My stomach— it's acting up again...!"
She wrapped both arms around her belly. The lower stomach that had just gone down swelled back up, visibly.
"Hnnngh... Minchul, I'm seriously gonna die...! I can't breathe. My stomach's gonna rip, I said!"
Tears hit the floor in drops. This wasn't about shame anymore. A few hours from now she'd be standing in front of executives in those white leggings, and it was obvious how that would go.
"Noona, get on your stomach."
"What?"
"Clenching won't get it out. Your intestines are kinked and the gas is trapped. I'll do an abdominal massage and clear the path, so lie face-down on the bed. Now!"
"How the hell do you know that."
"...I looked it up."
She stared at me like she couldn't believe her ears. Both of us were remembering the conversation at my place a couple of hours ago. This time she didn't ask what I'd searched.
She had no strength left to hold out, and no pride either. She crawled up onto the mattress on all fours, buried her face in the pillow, and pushed her ass back — chest dropped low, the full hips and apple-round ass wrapped in white leggings lifted high toward the ceiling.
Shhk... pfft.
"Haaang...! D-don't look... not in a pose this pathetic... hnnk?!"
Face in the pillow, she mumbled like she was screaming.
I climbed onto the bed anyway and knelt behind her. Then I slid both hands in along her sides and cupped the swollen lower belly.

A soft slide—
"Hiiik?!"
Her back snapped up like a bow.
"Stay still. I'm pushing it the way the large intestine runs."
Just like the pages I'd pulled up, I set my palm inside her right hip. The second I touched her, the feeling was strange. Every curve of intestine packed full of gas gave under my hand, clear as anything.
I steadied my breath and pressed in a wide clockwise circle.
Deep.
"Ah, aaaah—!! It hurts, it hurts, Minchul...! Nnh, that's too deep!"
She clawed at the pillow, but I didn't stop. I put my weight into the heel of my hand and pushed, slow.
In that moment I felt the huge bubbles trapped in her gut roll — a wet glug, a blorp — and shove their way down toward her rectum.
And immediately—
Prrrrrt!! Braaap!! Peeek!!
"Kyaaaaaah—!!"
The mattress shook. No matter how hard she tried to clamp down, my hand was dug into her lower belly, and high-pressure gas blasted out of the forced-open gap like a machine gun.
Brrrrt! Fshhhhh... pomp! Braaap!
The white cloth flapped like mad between her cheeks.
A stench past imagining filled the sealed room. Years of a high-protein diet had forged the flora in her gut, and the thick gas they poured out was exactly like sulfur steam rising off boiling mud in a hot-spring field.
My nose felt like it was going numb, but that brutal scent and her moans were the finest hit my warped libido had ever taken.
"Hahh... noona, more's coming. There's still a ton left!"
Breathing hard, I pressed myself against her like I was hugging her waist, and drove both hands deep under her navel.
A wet squelch—
Because I'd leaned in, the front of my pants — strained to bursting — landed flush against her ass.

"—Hh?!"
She was wringing farts out of herself while a column hard as an iron bar ground into the cleft of her cheeks.
"N-no... nnh, Minchul! If you keep pressing like that... aaang♥"
Her voice had gone completely. I couldn't tell if she was saying it hurt or telling me to stop.
"Haaaaang...! No, it's coming again...! Hnnngh?! Ah!!"
Psssssss... peeeeek... prrrrrrt.
I kept my hands sunk deep and held still, and whatever had been coiled in the deepest part of her came out thin and endless. Like someone had cracked a tire valve.
Through the whole long sound she clawed the sheets, thighs clamped, shaking.

"Ah, I'm— aaaaang!!"
She came. Crushed under the hands of the guy next door, spraying out a shameful fart as she hit it — the worst orgasm of her life, and the best.
In the end she collapsed onto the mattress.
Whatever that had been earlier, this time even she couldn't blame her muscles.
"Haa... haa..."
For a long while the only sound in the room was the two of us breathing.
She lay with her cheek buried in the pillow, panting. The white leggings had darkened in patches, soaked with sweat or something else entirely. The belly that had been bulging was flat as a lie, and the straight abs she'd always had showed through again.
5:40 a.m.
Drenched in sweat, I slowly took my hands off Seoyeon's back where she lay staring at nothing. My side still showed no sign of going down, but that was my problem.
"It's all flat."
She pushed herself up and leaned against the headboard. Then, like she couldn't believe it, she felt along the soaked leggings.
"It really vanished. I don't even know how many years it's been since my stomach felt this easy."
"That's a relief. You'll be fine for the morning session."
I let out a breath and started to climb off the bed.
She caught me.
Her leg shot out and hooked my waist. A trainer's arm snatched my collar and flipped me straight onto the mattress.
Thud.
When my head cleared, she was on top of me. Wet hair hung in front of my eyes.
"Noona?"
"Who said you could leave."
Her breath was hot. The eyes of someone who'd figured something out.
"My stomach feels insanely better. Now somewhere else is going crazy."
The corner of her mouth lifted.

"You pressed me like that from behind, and now I can't see straight."
"B-but you set the condition, noona. Don't touch you. Once I leave the room, it never happened."
"That was the condition for your room."
She grabbed the waistband of my training pants.
"This is my room."
I had nothing to say. I didn't want to argue anyway.
"Three hours until the session. You stirred my body up like this and you think you're going somewhere? You're taking responsibility until I leave for work. Got it?"
The pants were yanked down as the dark outside the window slowly began to lift.
