Aran's Intrusion
Eun-kyung lay draped over Min-gyu's lap, slowly rocking her hips.
"Hnn... haah... your cock... it's twitching inside me..."
She leaned forward, bracing both hands on the floor, arching her supple waist as she swallowed his shaft deep inside her. Every time her inner walls contracted, the tight, slick friction sent ripples through both of them.
Min-gyu could feel the burning heat of her depths clenching around the head of his cock.
Then the door behind them opened with a soft click.
A moment later it closed again.
"...N-noona...?"
Min-gyu turned his head in shock. Standing there with a calm expression, Kim A-ran twisted open the cap of a water bottle.
"No need to be surprised. Keep going. Go on."
She walked over as if nothing unusual was happening, approaching the pair without hesitation.
Eun-kyung didn't stop for even a second.
"...Haa... ahn... M-Master is... watching..."
She pushed her hips back even deeper. Wet, obscene sounds slid along Min-gyu's thighs as her pussy clung to him, squeezing his cock from every angle.
"...Hnn... haah... put it deeper... inside my pussy..."
Min-gyu’s eyes flew open at her words.
‘M-Master...?’
The word lodged itself in his ears.
‘What the hell...? Why is she suddenly calling someone Master...? Who is she talking to...?’
Below him the wet sounds never ceased. Above them, Min-gyu froze in panic, breath caught in his throat.
Unable to endure any longer, he sucked in a breath and tried to pull his hips back.
"...S-sorry, this is a bit..."
Just as he began to withdraw, a gentle hand settled on his shoulder.
"No, no. Don't pull out. It's fine, Min-gyu."
A-ran's voice was soft, but the strength in her fingertips was firm. She pressed down lightly on his shoulder to stop his movement, while her other hand tugged Eun-kyung's hips back, forcing Min-gyu's cock deep inside her again.
"...Hnn..."
Eun-kyung's waist trembled at the sudden thrust. Min-gyu swallowed a gasp at the heavy sensation of being buried to the hilt.
A-ran leaned against him naturally, her body pressing close. Her eyes curved with satisfaction.
"The teacher has something she needs to confirm right now. So go ahead and fuck her properly. Hehe."
"Don't be embarrassed. Isn't she cute, Eun-kyung~? You should make our Min-gyu feel even better, don't you think?"
At those words, Eun-kyung panted heavily and ground her hips back against Min-gyu.
"Haah... Master... your cock sliding into my pussy... feels so good... Thank you... for letting me ride Min-gyu... haah... haah... ahn... I'm going crazy..."
She clenched around him, voluntarily impaling herself deeper. Min-gyu turned his head slowly, skin prickling.
‘...Master? A-ran just called her Master...?’
His mind went blank, yet his cock remained trapped inside Eun-kyung's pussy.
A-ran casually grabbed Eun-kyung's hips with both hands. She began slamming the girl's pelvis down onto Min-gyu's shaft like a pestle in a mortar.
Each wet slap sent splashes of her juices across his thighs. The floor beneath them grew slick with lewd droplets.
"Haang... ah... your cock... feels too good..."
"Hnn... being pounded onto Master's cock... my pussy... feels like it's going to come..."
A-ran watched the scene for a moment before speaking again.
"Hmm. Most men would go soft in this situation... but Min-gyu, you're quite something."
She pressed harder, driving Eun-kyung down onto his cock once more.
"How is it? Doesn't it turn you on more with the teacher watching? Hehe, right? You've only ever fucked one girl at a time, and now there are two women here—one watching, one getting fucked."
"Doesn't that excite you a lot?"
Eun-kyung shivered in response, her hips twitching.
"Hnn... ah... yes... I'm excited... being taken like this... in front of Master..."
A-ran's expression suddenly turned cold. She gripped Eun-kyung's waist and drove a finger straight into her ass.
Because Min-gyu's cock was already buried deep, the finger pressed against it through the thin wall between her holes.
"...Hnn...!"
Min-gyu felt the strange pressure sliding along his shaft.
"How presumptuous..."
A-ran tilted her head slightly.
"Who gave you permission to interrupt when the Masters are talking, hm?"
Her finger pushed deeper and began thrusting.
"Haa... ah... it hurts... hnn...!"
Eun-kyung twisted her hips in pain, but A-ran didn't stop.
"How does it feel? Both holes stuffed full... doesn't it feel better, Papi?"
She twisted her finger inside, stimulating Eun-kyung's ass. Though her face twisted in discomfort, Eun-kyung desperately tried to smile.
"Y-yes... it feels... so good... Master... my pussy and ass... being filled together... haah..."
A-ran curled her finger and began stroking along the length of Min-gyu's cock through the thin membrane, rubbing, pressing, and scraping along his shaft from inside.
Min-gyu shuddered violently.
"F-fuck..."
A-ran glanced at his reaction and continued her lewd movements.
"Ooh... that rough swearing is kind of sexy. Min-gyu must have so many questions right now, right?"
She whispered while slowly twisting her finger as if about to pull it out.
"If you fill this bitch's pussy with cum, I'll answer everything for you."
Min-gyu was still confused, but one thing stood out clearly.
‘She just said “when the Masters are talking”... Does that mean she sees me as a Master too...?’
Rather than overthink it, he decided to act.
"Noona, shake your hips like a proper slut. I'm about to cum."
The moment the words left his mouth, his voice was surprisingly steady.
A-ran reacted immediately.
"Wow... amazing. You're doing great! Did you hear that, Papi?"
Her tone was genuinely praising. Min-gyu caught the implication at once.
‘She really does see me as a complete Master.’
A strange thrill sank deep into his chest. At the same time, the urge to climax surged powerfully through his cock.
Eun-kyung, lost in pleasure, could only moan with her mouth open. A-ran looked down at her and expressionlessly pushed in a second finger.
"Squish."
Eun-kyung jolted as her ass was suddenly stretched wider.
A-ran spoke sharply.
"What did I tell you to do when a man wants to cum!?"
Eun-kyung barely managed to answer through broken breaths.
"Hnn... my ass is... s-sorry... haah... I... I'll take it anywhere..."
A-ran leaned in closer, eyes sharp.
"Anywhere what!?"
"I'm just a public onahole for men... so please... use me however you want... haah..."
With both holes filled, Eun-kyung began moving her hips on her own.
"Haah... ahn... inside... both my pussy and ass... feel so good..."
Her pussy swallowed his cock with wet sounds while her ass clenched around the thrusting fingers. She rocked back and forth, chasing the dual stimulation at the boundary between her holes.
Min-gyu could no longer hold back. He grabbed her bound wrists and slammed his hips upward, pounding into her relentlessly.
Thud—! Thud—! Thud—!
Her juices spilled down her thighs as he drove into her. Eun-kyung's walls tightened desperately around him, and Min-gyu finally released deep inside her pussy.
Thick, hot cum spurted out in powerful bursts.
A-ran watched with a satisfied, almost entranced expression.
"Hmm..."
She looked at Min-gyu's face and asked softly.
"Did you finish...?"
Min-gyu answered between breaths.
"Yeah... pretty much..."
The moment he spoke, A-ran slowly withdrew her fingers from Eun-kyung's ass. With a wet sound, she nudged the girl's hips with her foot.
"Move, Papi."
Eun-kyung was pushed forward, and Min-gyu's cock slipped out of her with a lewd squelch. She collapsed forward, cum and juices dripping from between her legs as she panted.
A-ran wiped her hand carelessly on her clothes and smiled.
"Now then... shall we have a little Q&A session for Min-gyu, who has so many questions?"
