The humidity of Seoul hit me the second I stepped off the plane, a stark contrast to the crisp, biting air of Europe I’d grown accustomed to during my years at an international boarding school there as an exchange student. A strange mix of adrenaline and anxiety fluttered in my chest. After spending years away, I was finally back fully; back home, back in Seoul.
The HYBE CORTIS team had been surprisingly enthusiastic about my return. They didn't just offer me a ride; they turned my arrival into a full-blown production.
"The fans will love the 'big sister returns' narrative," They told me.
Cameras trailing me from the moment I claimed my luggage. I didn't really mind. In a way, the cameras felt like a shield, a way to distract myself from the nerves of seeing my little brother and the rest of the CORTIS boys after so long.
As the van pulled up to the HYBE building, my heart hammered against my ribs. I could see the familiar architecture, the buzz of activity around the entrance. The staff guided me inside, the cameramen whispering instructions to stay out of the way but keep the frame wide. What ever that means.
We walked toward a training room. I could hear them before I saw them; the chaotic blend of laughter, loud shouting, and the heavy bass of a track playing in the background. I stopped at the door, taking a deep breath.
I stepped into the room.
The space was massive, mirrored walls, everything. They were in the middle of a crossover session, CORTIS and ENHYPEN blending together in a mess of oversized hoodies and sweatpants. They were joking around, some leaning against the walls, others sitting down.
I stood there for a moment, just absorbing the sight of them.
Seonghyeon stopped mid-sentence, his eyes locking onto mine. His jaw practically dropped. “He blinked once, twice, checking that he was hallucinating.”
"Aria- Noona?!" he yelled, his voice cracking slightly.
A small laugh escaping my lips.
The moment my name left Seonghyeon's mouth, the room shifted. Keonho, who had been laughing at something Jay was saying, whipped his head around. His eyes widened, and for a split second, he looked like he’d seen a ghost. Then, the shock turned into pure, unadulterated joy.
"WHAT! NO WAY!" Keonho screamed. He sprinted. He launched himself at me, his arms wrapping around my waist and lifting me off the ground in a crushing hug. "You're back! You're actually back!- You didn't tell me you were coming today!"
I laughed, hugging him back tightly, feeling the familiar warmth of my little brother. "Surprise!"

NI-KI’S POV
I was leaning against the mirrored wall, half-listening to James talk about the choreography for the TikTok trend we were about to film. I was bored, my mind drifting, until the door opened.
I saw her before anyone else did.
She walked in with a quiet, almost hesitant grace, flanked by the filming crew. My eyes tracked her immediately. She was stunning; not just 'pretty,' but captivating-... hot.
I didn't know who she was, but I felt an immediate, magnetic pull. I found myself staring, my gaze lingering on the curve of her lips and the way her hair fell over her shoulders.
Who is that? I wondered, my pulse quickening. She’s gorgeous.
Then, the chaos erupted. Seonghyeon screamed her name, and Keonho, who usually acted like he had the world figured out lost his mind. He tackled her with a hug that looked like it might snap her in half.
I leaned closer to James, my voice low, a hint of curiosity masking the sudden hunger I felt. "Who’s that?"
James glanced over, then looked back at me with a knowing, slightly warning expression. He laughed, what was so funny?
"Yeah, I know... she’s pretty, right? But take it out of your head, Ni-Ki. That’s Keonho’s big sister."
I froze, my eyebrows knitting together. "Big sister?"
"Yeah," James explained, shaking his head. "Ahn Ariana. Keonho’s big sister. She’s also twenty, just finished school in Europe. She’s basically the queen of there family; Keonho is insanely protective of her. Like, 'will-fight-anyone-who-breathes-near-her' protective."
I didn't respond, but I didn't look away. I watched as she laughed, her face lighting up as she greeted the other CORTIS members. The way she smiled made something stir deep in my gut. The fact that she was Keonho's sister didn't make me want her less; if anything, the forbidden nature of it added a spark of challenge.
“She was out of my league in every possible way, but as I watched her, I realized I didn't care about the rules.
I just wanted to know what she tasted like.
END NI-KI’S POV

After the initial shock wore off, the rest of the CORTIS boys piled in. Juhoon and the others crowded around me, hugging and teasing me about how "European" I looked now.
These boys had always been like brothers to me, and being back in their orbit felt like coming home. But as the huddle broke, I realized I wasn't the only one in the room.
I turned around and felt a sudden, sharp prickle of heat on my skin. Fourteen pairs of eyes were locked on me. The members of ENHYPEN.
Martin stepped forward taking his leader role. "Ahh, Noona," he said, his voice smooth. "This is ENHYPEN, this is-."
He started going down the list, but I felt my face heating up. I couldn't help it; I knew exactly who they were. A shy smile playing on my lips. "Oh, yeah... I know. Nice to meet you guys" i said bowing down.
Keonho decided to be the absolute menace he is. He smirked, leaning into my side and shouting, "She’s an ENGENE! She has a whole secret folder of photos-"
"Keonho! STFU!- " I hissed, pressing my hand over his mouth.
Jay laughed, a rich, melodic sound. "Ahhh, is that so? That's lovely to hear! We're honored." he said also bowing now.
I bowed awkwardly, my heart racing. God kill me
As the session transitioned into filming, I retreated to the side of the room. I sat on a bench, watching the chaos unfold. Some of the boys were already filming their collabs, while others were practicing the footwork.
Juhoon and Martin were waiting for their turn, so they sat with me, chatting about my time in Europe and the graduation ceremony.

NI-KI’S POV
James was talking, but I wasn't listening. I was looking at her in the mirror.
Aria
She looked so innocent sitting there, laughing with Juhoon and Martin, but there was something in the way she shifted her weight, the way she bit her lip when she thought no one was looking, that told me she wasn't as innocent as she appeared.
I caught her eye in the reflection. I didn't blink. I wanted her to know I was watching.
"Take it out of your head, Ni-Ki!" James whispered, nudging me hard in the ribs. "She’s Keonho’s big sister. He’ll literally kill you! We can’t even compliment her without Keonho giving us a death glare- Plus..." James lowered his voice, leaning in. "I think she just got out of a toxic relationship."
I snapped my head toward James, my interest piqued. "Huh? What?"
"Yeah, Keonho told us. They broke up recently. Some guy from her school in Europe. Keonho hated him! Said the guy was controlling, a total nightmare. She graduated a few weeks ago."
I processed this, my gaze drifting back to Aria. A toxic relationship? She was fragile, but she was free. And I had always liked things that were a little bit broken, because that meant I could be the one to put them back together—or break them further.
END NI-KI’S POV

Eventually, Martin and Juhoon were called back to the center of the room to film their stuff. I was left alone on the bench, the loud music of the training room filling the silence. I leaned back, closing my eyes for a second.
Suddenly, the bench dipped.
I opened my eyes and gasped slightly. Ni-Ki had slid into the seat next to me. He was so close that I could smell his scent; a mix of expensive cologne and sweat. He was leaning back, one arm draped over the back of the bench.
"I hope you don't mind me sitting here?" he asked. His voice had dropped an octave, sounding husky and intimate.
"No... no, of course not," I stammered, my heart leaping into my throat.
"So..." he started, his voice a low purr. "You're an ENGENE?"
I felt the blush return with a vengeance. I covered my face with my hand, letting out a frustrated groan. "Keonho is so annoying... putting me on the spot like that in front of everyone!"
Ni-Ki laughed. It wasn't a loud laugh; it was a soft, private sound that felt like a secret shared between us. He turned his head, leaning forward, his face just inches from mine. I could see the gold flecks in his dark eyes, the intensity of his focus.
"So," he whispered, his breath warm against my cheek. "Who's your bias? Hm?"
The teasing tone was unmistakable. He knew exactly what he was doing. He was playing with me, pushing my boundaries.
"I'm not telling you that!" I replied, trying to sound firm, but my voice wavered.
Ni-Ki chuckled, a smirk spreading across his lips. "Awh, why not? You’re letting me think it’s me."
I blinked, stunned by his audacity. "Why would it be you?"
"Because you're not saying it," he countered, his voice dropping even lower, becoming a vibration I could feel in my own chest. "That means it's me. You're too embarrassed to admit you're into me."
"It's not!" I protested, though my heart was drumming a frantic rhythm against my ribs.
"Hmmm," he hummed, his eyes scanning my face, lingering on my lips.
I felt a surge of boldness, a reaction to the tension that had been building since I walked into the room. "And what if you were my bias? Then what?"
The atmosphere shifted instantly. The teasing vanished, replaced by something raw and hungry. Ni-Ki didn't pull away. Instead, he leaned in further, his lips almost brushing the shell of my ear. He shifted his weight, his thigh pressing firmly against mine, the heat of his body searing through my clothes.
"It would make things easier," he whispered, his voice dripping with a bold, sexual promise. "Because if I'm already your favorite, it means you've already imagined me. It means you've thought about how it would feel to have me push you against these mirrors and fuck the breath out of you until you forget your own name."
I gasped, my breath hitching in my throat. I couldn't move; I was paralyzed by the sheer intensity of his words.
"I can see it in your eyes, Aria-”
“Ni-Ki! James waiting for you!” A staff members yelled from across the room.

You had just finished swimming, and your so-called friends had ditched you without a word. Annoyed but too tired to care, you grabbed your towel and spare clothes, heading straight for the showers.
You glanced at the signs on the two stalls. Both looked like female symbols. Without thinking twice, you pushed open the door and stepped inside. The nameplate on the front had slipped off earlier, revealing the truth this was the men’s bathroom.
It was quiet and empty. You chose the last stall, pulled the curtain shut, and quickly peeled off your wet pink sporty swimwear. The cool air brushed against your bare skin as you set the swimsuit aside. Completely naked now, you turned on the shower, letting the warm water cascade over your body. You ran your fingers through your wet hair, rinsing off the chlorine, when you suddenly realized you had forgotten your soap and shampoo.
Just then, you heard footsteps. Someone had entered the bathroom.
Luckily, you spotted a bottle of school-provided soap and shampoo on the small shelf inside the stall. You turned off the shower, wrapped one arm loosely across your chest, and peeked out from behind the curtain — just enough to show your wet hair and bare shoulders.
“Excuse me, can you please—”
Your voice died in your throat.
It wasn’t a girl.
A tall guy stood there, frozen mid-step, eyes wide as he stared at you. His mouth parted slightly, clearly trying to process the situation. Before either of you could react, the main door creaked open again — more voices echoing as a group of guys walked in.
In a flash, he moved. He rushed forward, slipped into your stall, and pulled the curtain closed behind him. You stumbled back in shock as he gently but firmly pushed you deeper into the stall, his hand landing on your bare waist.
Your eyes widened in recognition.
It was Sunoo — the handsome senior from the engineering department.
He was still fully dry in his casual clothes, standing inches away from your completely naked, dripping body. His warm palm remained pressed against the curve of your waist, steadying you… or maybe steadying himself. His breath was shallow, his dark eyes locked onto yours in stunned silence as the voices of his friends grew louder just outside the thin curtain.
You wanted to argue so badly — to push him away and hiss at him for barging in — but the voices of his friends right outside the thin curtain made you freeze. Any sound could give you both away. So you stayed quiet, heart hammering in your chest, cheeks burning with embarrassment and shock.
Sunoo’s eyes flicked toward the curtain for a split second, then back to you. Without a word, he slid closer, his body pressing lightly against yours as he reached for the shower knob. His clothes brushed against your wet, naked skin, sending a shiver down your spine. He turned the water on, letting the spray hit the wall first before adjusting it so it would sound like someone was actively showering.
The sound of running water filled the stall, masking your quick, shallow breaths.
His friends’ voices echoed loudly now, laughing and talking about practice, completely unaware. One of them even tried the stall next to yours before moving on.
Sunoo kept one hand firmly on your waist, steadying you under the warm spray. Water began soaking into his shirt, making the fabric cling to his chest. He was so close you could feel the heat radiating from his body, his breath brushing against your wet hair. His dark eyes met yours again, a mix of apology and panic in them.
He leaned in slightly, lips barely an inch from your ear so only you could hear.
“…Sorry,” he whispered, voice low and slightly hoarse. “Just… stay quiet for a minute. They’ll leave soon.”
His fingers unconsciously tightened on your bare waist as another burst of laughter came from outside. The water continued to cascade over both of you now, drenching him completely while you stood there, heart racing, trapped between the cold tiles and his tall frame.
You were still completely naked.
He was fully clothed — but getting wetter by the second.
And neither of you could move without risking everything.
You hated it.
You hated how his low, husky whisper sent a warm shiver straight through your body. The way his breath brushed your ear made your stomach tighten in a way that had nothing to do with fear. Fuck, you thought, cheeks burning hotter than the shower water. You just nodded quickly, not trusting your voice.
You couldn’t even look at him directly. Every time your eyes tried to meet his, your heart stuttered. Instead, you kept your gaze lowered, staring at the wet fabric clinging to his chest. But curiosity won for a split second — you glanced up.
Fuck… he’s handsome.
Even soaked, Sunoo looked unfairly good. Wet strands of hair stuck to his forehead, water sliding down his sharp jawline. His usual calm, composed senior vibe was cracking under the situation, replaced by flushed cheeks and slightly parted lips. His dark eyes were locked on your face, careful not to let his gaze drift lower, though you could tell he was fighting it.
He noticed your quick glance. For a moment, something shifted in his expression — a flicker of heat mixed with panic.
The voices outside grew louder as his friends joked around, one of them yelling something about waiting for Sunoo. The running water was the only thing keeping your secret safe.
Sunoo’s hand was still on your bare waist, his fingers now lightly pressing into your slick skin as if he didn’t realize he was still holding you. The thin curtain and the sound of the shower were the only barriers between you and total humiliation.
You swallowed hard, painfully aware of how close his body was to yours. Every small movement made his wet clothes brush against your breasts and stomach. The heat between you two was getting harder to ignore.
He leaned in again, voice even lower this time, almost a breath
“…You okay?”
His eyes finally dropped for half a second — just long enough to take in the sight of your naked, dripping body pressed against him — before snapping back up to your face. His Adam’s apple bobbed as he swallowed.
You nodded again, biting your lip.
Neither of you dared to speak after that. The only sounds were the shower running and the heavy beat of your hearts.
You felt like you were losing your mind.
A deep, aching heat had settled low in your stomach, pulsing uncomfortably between your legs. It wasn’t just nervousness anymore. The way Sunoo’s wet body was pressed against yours, his fingers still gripping your bare waist, the sound of his breathing so close to your ear — it was making everything worse. Your thighs pressed together instinctively, but that only made the throbbing sharper.
Shit… not now. Not here.
You hated how your body was betraying you. The warmth spreading through your core, the way your nipples had hardened against his soaked shirt… damn it. You wanted to squirm, to clench your legs tighter, to do something to ease the building pressure, but you couldn’t. Any movement, any sound, and his friends right outside the curtain would hear.
Sunoo was still watching you, his dark eyes searching your face. He must have noticed the way your breathing had changed — quicker, shallower. His grip on your waist tightened slightly, almost like a silent question.
You shook your head very lightly, biting down hard on your lower lip. You couldn’t speak. You couldn’t even shift your weight without the water splashing differently. All you could do was stand there, completely naked and dripping, while unwanted heat kept pooling between your thighs.
Sunoo leaned in closer again, his lips brushing the shell of your ear as he whispered, barely audible over the running shower
“…Breathe. I’ve got you.”
His voice was lower than before, a little rougher. You didn’t miss how his thumb unconsciously stroked your wet skin, slow and soothing. The front of his soaked pants was now pressed lightly against your hip, and you could feel he was getting hard too.
That realization only made the ache between your legs intensify.
You closed your eyes tightly, trying to fight the wave of heat crashing over you. Your friends had ditched you. You were stuck in the wrong bathroom. And now the unfairly handsome senior engineering student was trapping you against the wall, both of you soaked, while his friends laughed and chatted just a few feet away.
And all you could think about was how badly you needed relief.
You couldn’t take it anymore.
The throbbing between your legs had grown unbearable. Every tiny shift of your body made it worse, and Sunoo’s warm, wet frame pressed so close only intensified the ache. Your heart was racing, your breathing shaky. You had to say something before you lost control.
With the shower still running loudly, you leaned in just enough so your lips nearly touched his ear. Your voice came out as a trembling, barely audible whisper
“…Sunoo… I-I can’t… it feels too much down there.”
The words left your mouth and you immediately regretted how needy they sounded. Your face burned with shame, but the confession was out. You kept your eyes squeezed shut, too embarrassed to look at him.
Sunoo froze against you.
His hand on your waist tightened, fingers digging into your slick skin as he processed what you’d just whispered. You felt his chest rise sharply against yours, his breath hitching. The front of his soaked pants twitched noticeably against your hip — he was definitely harder now.
He pulled back just enough to look at your face, his dark eyes wide with shock and something much hotter. Water streamed down his flushed cheeks as he stared at you, lips parted.
For a few long seconds, he didn’t speak. Then he leaned back in, his wet hair brushing your forehead, and whispered so quietly you barely heard him over the water
“…Fuck. You’re serious?”
His voice was hoarse, strained. His free hand came up to rest on the tile beside your head, caging you in as his body pressed a little closer despite himself. The new angle made his clothed thigh accidentally brush right between your legs, right against your aching core.
You had to bite your lip hard to stop any sound from escaping.
Sunoo’s eyes darkened. He looked like he was fighting every instinct he had.
“Tell me what you need,” he breathed against your ear, voice shaky but gentle. “Quickly… before they hear us.”
His friends were still chatting and laughing outside, completely oblivious, but the tension inside the stall had just skyrocketed.
You wanted to speak so badly.
You wanted to tell him exactly how badly your body was aching, how the throbbing between your legs was driving you crazy, how his thigh pressing against you was making it ten times worse. But fear sealed your throat. Any sound louder than a breath could alert his friends just outside the curtain. So you stayed silent, trembling, eyes glassy with desperation.
Sunoo studied your face for a heartbeat, reading the unspoken plea in your expression. His jaw clenched. Then he gave a tiny nod, understanding.
Without another word, he slowly slid his hand from your waist, down over your hip, and between your thighs. His touch was careful, almost hesitant at first. Two fingers gently parted your folds, finding you slick and swollen with arousal. The moment he brushed against your clit, your knees buckled. You grabbed onto his soaked shirt with both hands, burying your face against his chest to muffle any sound.
He started moving — slow, quiet circles against your most sensitive spot. The warm shower water mixed with your own wetness, making every glide smooth and torturously teasing. His fingers were skilled, pressing just enough to give you relief without making noise.
You bit hard into his shoulder through his wet shirt, eyes squeezed shut as pleasure spiked through you. A tiny, broken whimper almost escaped, but Sunoo quickly pressed his lips to your ear.
“Shhh…” he breathed, barely audible. “I’ve got you. Just breathe.”
His other arm wrapped around your back, holding you steady against him while his fingers continued their secret work — rubbing faster now, then slowing down when your breathing grew too ragged. Every stroke sent sparks up your spine. You were soaking his hand, thighs shaking uncontrollably.
The voices of his friends outside rose and fell, laughing about something stupid. The risk only made everything feel more intense.
Sunoo’s own breathing was uneven, his hardness pressing insistently against your hip through his soaked pants. He was clearly affected too, but he stayed focused on you, curling his fingers lower to tease your entrance before returning to your swollen clit with perfect pressure.
You wanted to moan his name. You wanted to beg him to go faster. Instead, all you could do was pant softly against his neck and roll your hips desperately into his hand, chasing the building pleasure in complete silence.
He pressed a soft, lingering kiss to your temple — almost sweet despite the filthy situation — and whispered hotly against your skin
“That’s it… cum for me. Quietly.”
Your body tensed hard as the pleasure finally crashed over you. You buried your teeth into Sunoo’s shoulder through his soaked shirt, biting down to stop yourself from crying out. A powerful orgasm ripped through you, making your thighs shake violently and your walls clench around nothing. You came hard on his fingers, hips jerking against his hand while the shower water continued to rain down on both of you.
Sunoo’s breath hitched sharply. Feeling you come undone, feeling how wet and tight you were, finally made him lose control.
He pulled his hand away from between your legs, breathing heavily. For a moment, he just stared at you — eyes dark with lust, hair dripping, lips parted. Then he slowly looked into your eyes, his gaze asking the silent question.
is it okay
You nodded quickly, desperately, still trembling from your orgasm.
That was all the permission he needed.
Sunoo stepped back just enough to peel off his wet clothes. His shirt hit the floor with a heavy splash, followed by his pants and boxers. In seconds, he was completely naked, his hard cock springing free, flushed and leaking at the tip. He kicked the soaked pile of clothes to the corner of the stall.
You leaned back against the cool tiled wall for support, chest heaving. Sunoo moved in again, tall frame pressing close. He hooked one of your legs over his hip, adjusting his position carefully. The head of his cock nudged against your slick entrance, sliding up and down your folds teasingly.
Just as he pushed forward — the thick tip stretching you open — your mouth fell open in a silent moan. Before any sound could escape, Sunoo’s large hand clamped firmly over your mouth, muffling you completely.
“Shhh…” he whispered hotly against your ear, voice strained with lust.
He sank deeper inside you in one slow, steady thrust, burying himself to the hilt. His eyes rolled back for a second at how tightly you wrapped around him. He stayed still for a moment, letting you adjust, forehead pressed against yours as both of you struggled to stay quiet.
Outside the curtain, his friends were still talking and laughing, completely unaware that Sunoo was balls-deep inside you just a few feet away.
His hand stayed pressed over your mouth as he slowly rolled his hips, starting to fuck you against the wall — deep, careful strokes that made your eyes water with pleasure.
Sunoo’s thrusts grew faster, deeper, and much riskier.
He was fucking you harder now, the wet sound of skin slapping skin starting to mix with the shower spray. Every stroke pushed you up against the tiled wall, your breasts bouncing with the force. The risk of getting caught only seemed to make him more desperate.
He suddenly pulled his hand away from your mouth. Before you could even gasp, he cupped the back of your head and crashed his lips against yours in a hungry, messy kiss.
You moaned into his mouth — soft and needy — and he swallowed every sound. His tongue pushed past your lips, tasting you deeply as he fucked you faster. The kiss was wet, sloppy, and intense, muffling your whimpers while his hips snapped against yours.
“Fuck… you feel so good,” he breathed against your lips between kisses, voice hoarse and barely above a whisper.
He angled his hips and drove into you even harder, hitting that perfect spot inside you with every thrust. The stall shook slightly. Water splashed everywhere. The wet sounds were getting louder.
Outside, his friends were still there. One of them laughed loudly and said, “Yo, where the hell is Sunoo? He’s taking forever.”
The voice was so close it made your pussy clench hard around him in panic and arousal. Sunoo groaned quietly into your mouth, his grip on your thigh tightening as he pounded into you faster, chasing his own pleasure now.
He broke the kiss for a second, pressing his forehead to yours, both of you panting heavily.
“You’re gonna make me cum…” he whispered hotly, eyes half-lidded with lust. His cock throbbed inside you, thick and relentless.
He kissed you again, deeper this time, biting your lower lip as his pace turned almost frantic — risky, noisy, and completely addicted to the feeling of your tight heat around him.
Your second orgasm was already building fast, dangerously close, while his friends lingered just outside the curtain, still chatting and waiting for him.
Sunoo suddenly pulled out of you, making you whimper at the loss. In one swift, strong movement, he gripped the back of your thighs and lifted both your legs off the ground, wrapping them around his waist. Your back pressed harder against the cold tiles as he held you up effortlessly, your body completely suspended between him and the wall.
His cock nudged your entrance again before slamming back inside you in a single deep thrust. The new angle was devastating — he reached even deeper, hitting spots that made your eyes roll back.
“Fuck—” you choked out against his lips.
He kissed you again, hard and desperate, swallowing your moans as he started fucking you with reckless intensity. The position allowed him to drive into you faster and harder. Wet, filthy sounds of his hips slapping against your ass echoed inside the stall, barely covered by the shower.
Your arms wrapped tightly around his neck, nails digging into his shoulders as he bounced you on his cock.
The pleasure built dangerously fast. Your second orgasm hit you like a wave.
You came hard around him, pussy clenching and pulsing, thighs shaking violently in his grip. A broken, high-pitched moan escaped into his mouth. Sunoo groaned deeply, kissing you even more messily to silence you as your walls fluttered and squeezed him.
The feeling of you cumming pushed him over the edge.
“Shit… I’m cumming—” he gasped against your lips.
With a few final, brutal thrusts, Sunoo buried himself as deep as possible and came inside you. Thick, hot spurts of his cum flooded your pussy, filling you up while he held you tightly against the wall. His hips jerked, grinding into you as he rode out his orgasm, groaning quietly into your neck.
Both of you stayed locked together, panting heavily, bodies trembling. His cock was still buried deep inside you, twitching with the last drops of his release. Cum was already starting to leak out around him, mixing with the shower water running down your thighs.
Outside the curtain, one of his friends shouted, “Sunoo-ya! Hurry up, man! We’re waiting!”
Sunoo froze, still holding you up with both legs wrapped around him, his cum dripping out of your used pussy. He looked at you with wide, hazy eyes — a mix of satisfaction, panic, and lingering lust.
He pressed a soft, breathless kiss to your lips and whispered against them
“…We’re so fucked.”
Sunoo’s chest was still heaving, his cock buried deep inside you as he tried to steady his breathing. Even through the aftershocks of his orgasm, he managed to lift his head and shout toward the curtain in a surprisingly steady voice
“I’ll catch up! Just go ahead without me!”
His friends groaned and teased him for a second, but they sounded convinced.
“Alright, don’t take too long, dude!”
Their voices faded as they laughed and talked about random things — practice, food, some upcoming exam — until the bathroom door finally clicked shut behind them.
Silence.
You were finally alone.
“Fuck…” you breathed out, voice hoarse and shaky now that you could actually speak.
Sunoo pulled back just enough to look at you, his eyes still dark with lust. A slow, dangerous smirk tugged at his lips. He was still holding both of your legs wrapped around his waist, his cock still hard and twitching inside your cum-filled pussy.
“Yeah… fuck is right,” he whispered, voice low and rough.
Without warning, he started moving again — slow and deep at first, pushing his cum even deeper into you with every thrust. The sound was wetter now, obscene squelching noises filling the stall as his load leaked out around his cock.
But being completely alone changed everything.
Sunoo’s pace quickly picked up. He fucked you harder, slamming into you with long, powerful strokes. Your back slid against the wet tiles as he railed you, the wet slapping sounds echoing freely in the empty bathroom.
“Again,” he growled against your neck, biting down gently. “I want you to cum again.”
He adjusted his grip, spreading your legs wider as he drove into you relentlessly. The new freedom made him bolder — louder. His moans mixed with yours, no longer needing to stay quiet.
You could barely think straight. His cock kept hitting that perfect spot, and the feeling of his warm cum being fucked in and out of you was driving you crazy.
Sunoo pulled out of you with a wet sound, making you whimper at the sudden emptiness.
“New position,” he said huskily.
He sat down on the small built-in bench inside the stall, water still cascading over both of you. Then he pulled you onto his lap, facing him — your knees straddling his thighs in a seated cowgirl position. The moment you lowered yourself, his cock slid back inside your cum-filled pussy in one smooth glide.
“Ride me,” he groaned, hands gripping your ass tightly.
You braced your hands on his shoulders and started moving, rolling your hips and bouncing on his cock. The new angle made him feel even deeper. Sunoo leaned back against the wall, eyes locked on your bouncing breasts as you rode him harder, the wet sounds echoing shamelessly now that you were alone.
“Fuck, you look so good like this…” he muttered, thrusting up to meet your movements.
After a few intense minutes, he suddenly lifted you off him. Before you could protest, he dropped to his knees on the wet floor in front of you, pushed your back against the wall, and threw one of your legs over his shoulder.
His mouth was on you instantly.
Sunoo licked a long, hungry stripe up your pussy, tasting both your juices and his own cum. He moaned against your folds, the vibration shooting pleasure through you. He ate you like a man starved — sucking on your swollen clit, fucking you with his tongue, and licking up every drop of his cum that leaked out of you.
“Ah— Sunoo!” you moaned freely, fingers threading through his wet hair, pulling him closer.
He looked up at you with dark, lust-filled eyes while his tongue worked relentlessly. Two fingers joined his mouth, curling inside you as he sucked hard on your clit. Your legs started shaking again within seconds.
You came hard on his tongue, thighs clamping around his head as you cried out. Sunoo didn’t stop — he kept licking you through your orgasm until you were pushing at his head from oversensitivity.
When he finally stood up, his cock was rock hard again, flushed dark and throbbing. He leaned against the wall, breathing heavily, water running down his toned body.
Your turn.
You dropped to your knees without hesitation, the shower water spraying over your back. You wrapped your hand around his thick cock and took him into your mouth in one go.
“Shit—!” Sunoo hissed, head falling back against the tiles.
You sucked him eagerly, bobbing your head, swirling your tongue around the tip, and taking him as deep as you could. The taste of your mixed juices coated your tongue. Sunoo’s hand gently held the back of your head, guiding you but not forcing, soft groans and curses spilling from his lips every time you hollowed your cheeks.
“You’re too good at this…” he panted, hips twitching. “Keep going, baby.”
After a few more minutes of you sucking him eagerly, Sunoo’s breathing turned ragged. His hand tightened gently in your wet hair.
“I’m close—” he warned, voice strained.
You looked up at him and took him deeper, sucking harder. With a low, broken groan, Sunoo came hard in your mouth. Thick ropes of his cum spilled onto your tongue as his cock pulsed between your lips. You swallowed every drop, milking him until he was trembling and gently pulling you off.
“Fuck… you’re incredible,” he whispered, helping you stand up.
You both finally took the chance to clean up properly. Sunoo grabbed the school-provided soap and shampoo. Under the warm spray, you washed each other — his hands gentle but lingering as he soaped your breasts, back, and between your legs. You returned the favor, running your hands over his toned chest and abs, smiling shyly when his cock twitched again at your touch.
After rinsing off, you both stepped out of the stall. Sunoo quickly went to his locker near the sink and grabbed the spare clothes he had left there earlier. He lent you his clean oversized hoodie while you changed back into your extra clothes. You dried your hair with a towel and brushed it in front of the mirror.
“I’m Y/N,” you said softly, glancing at him through the reflection. “Second year, Architecture.”
Sunoo smiled — a bright, charming smile that made your heart skip. He was drying his hair roughly with another towel.
“I’m Sunoo. Engineering senior,” he replied, still smiling. “Nice to officially meet you, Y/N.” He paused, then added with a playful glint in his eyes, “Wanna grab coffee? My treat.”
You couldn’t help but smile back. “I’d like that.”
You both walked out of the swimming complex side by side, the tension from earlier slowly turning into a warm, fluttering feeling.
Just as you reached the courtyard, two familiar voices called out.
“Y/N! There you are! We were looking for—”
Samantha and Yukuzi stopped mid-sentence. Their eyes widened when they saw who you were walking with.
Kim Sunoo.
They both looked completely starstruck, mouths slightly open.
“Uh… we wanted to—” Samantha started, still staring at Sunoo.
“Maybe later,” you said calmly, cutting them off with a small wave. “I’m kind of busy right now.”
Without waiting for their reply, you continued walking with Sunoo. He glanced down at you, amused, and quietly slipped his hand into yours.

••••••••• ••••••••• ••••••••• •••••••••
a night so eery..
So cold, so alone. So empty and so full of nothing. Where was he? The question lingered.
It lingered in an empty air of nothing. Questions you asked, he left unanswered. Invites you sent, ignored. Begging and pleading all to be left with nothing but your own thoughts.
It was never meant to be like this, yet it was. Until it wasn't..
••••• •••••
As you lay in your empty bed, the bed you'd shared with him countless nights. Countless nights of longing, love and yearning. Yearning for his touch, not his presence.
Your door unlocked, your heart skipped. You knew who it was, of course you did. Tonight, it felt different. It didn't feel as if he was there. As if it were him.
Before you could even step out of your big bed of nothing, soft knocks sounded. You knew he was coming over, it'd been ages and you'd been counting down the minutes. So why were you nervous?
••••• •••••
He opened the door slow and soft. His eyes scanned over you, in white. So calm, soft and quiet. He knew better.. he knew what you were thinking through it all. He always had, until he wasn't so sure anymore.
He stepped in slowly, the door shutting behind him with a soft thud. He let out a breath he didn't know he was holding. Eyes trailing over you..
Before he could utter out a word, a greeting, some type of confirmation that he was actually there. You beat him to it.
"Hi.."
Fuck. Such a simple word, yet it hurt. His heart ached, for you.
"Hey.." He uttered, never as soft as you could. He watched your eyes trail him. He approached closer.. slowly. It's as if he was being weighed down on. As if his body was telling him this would never be good for you.
He couldn't stand the way your eyes trailed him. With so much concern, ache and confusion. Eyes that searched for answers, that he wouldn't give. Until tonight..
••••• •••••
Your eyes trailed, the tears wanting to build as you laid against your headboard. It felt like forever since you'd seen him, that face. That body, more so..his presence. The one thing you'd been craving as if it'd been years.
Now he was here, infront of you. Breath hitched, eyes trailing over you as if he was just as concerned. He sat on the edge of the bed. His head turned.
Until it found your eyes once more, as if it were the only thing they'd ever long for. Your breath hitched as he began to speak..
"How do I even..." He took a breath, eyes finding the ceiling. "You've asked questions.. and I've what?..given you nothing." He looked at you, and you nodded. It was the confirmation he seemed to look for.
Before he could continue, you spoke. "For weeks at that.." His eyes averted. "I pleaded for answers, I asked and I asked." You paused.
"And you somehow..always shut me out. As if what? I'm nothing?.. we're nothing?.."
Tears threatened you, and you noticed they threatened him. Yet he remained silent, averting your gaze. The eyes you'd missed so much wouldn't even look at you with remorse.
••••• •••••
"Fuck.." He trailed.. "I never meant for it to be like this. Ever." He spoke, a breath following.
And his gaze?..stayed away from her. He knew that one look, and he'd break too. It was true, he never meant for it to be like this.
For them to break, for him to ever turn his back on the person he yearned for most. It wasn't just her he shut out, he'd shut many out. Yet the relationship that hurt was yours.
"I..I don't know what's been going on." His gaze fell to his lap. "It started small, just remarks and thoughts. Something I thought I'd get over."
"Until they grew." He looked at the wall across from him.
"They weren't just thoughts anymore, they were feelings. I..I couldn't.. I can't ignore them." His breath hitched as his eyes shut momentarily.
"Frankly..I don't know when it started."
••••• •••••
But you did. You knew the exact date where the first day of nothing came around. You tried to ignore it until it grew, until he grew apart.
Your eyes trailed him as he continued,"soon enough, I felt as if for you..I wasn't enough."
His adam's apple bobbed as he gulped. You noticed, of course you did. Because you were becoming just as worried.
"Then it continued..my thoughts grew, and my next concern wasn't who I was, but what I was."
••••• •••••
His arms went behind him, propping him up as he leant back. There, it was out..was it all your questions answered? Nope.
But it was enough to paint the rest. He still couldn't fathom a look at you. Eyes trailing the paintings on your wall. Landing on one he'd made for you.
Then he heard it..a soft sniffle. He gulped. He knew this would happen, because it was always leading up to this moment..he knew you knew.
That tonight, could be the last.
He had never intended on hurting you for these past few weeks. Except that's all it was, weeks filled with hurt and feelings of unworthiness.
All because of insecurity.
His eyes trailed to yours, finally. Tears were rolling down you face. So he scooted closer. Until his hands cupped your face.
And before he could, you did. Your lips moved with a rythym so smooth.. it was memory for the both of you.
A memory that would remain a final.
••••• •••••
Your lips crashed onto his, you bit his lip with hurt. Your tongue slipped in, dancing with his as if it'd be the last. You knew it would, but hope was a dangerous thing.
His lips found their way to your your jaw. Trailing further to your neck..leaving soft open kisses. Then, the bite came on the one spot he knew was your most sensitive.
He sucked to mark, licked to sooth. A movement so familiar to him. To you.
Your hands entangled into his locks. His soft locks you'd always adorned. Any chance you had, you took. No matter where, what or when.
His lips stayed busy, his hand coming to a rest on your hips the other finding its way into your shirt. Thumb softly tapping your nipple.
Slowly, his mouth trailed to your collarbone. His hand started to pinch and roll the bud beneath his fingers. A sensation you'd miss.
••••• •••••
His lips left you, his hand remained teasing. He took in your face..wanting to have a memory to forever remember.
Who knew if your paths would ever cross again?
He kissed you again. This time it was full of love and hope. A hope that one day, you'd be back. He, would be back.
Soon enough, you were under him. Both of your clothes discarded on your rooms floor. His mouth worked wonders on you.
He delivered soft kisses to your clit, two fingers pumping you inside. Your thighs wrapped around his head, hands tugging at his locks.
"Fuck baby.." He groaned. He would miss worshipping you. He'd miss the taste, the sensation.. fuck even the way you whimpered and moaned under him.
It was a melody, one he never wanted to end.
••••• •••••
You moaned and gasped under his touch. He always worked wonders on you. It was second nature to him.
"Ki..oh my gosh.." You moaned as he added a third finger. His free hand coming up to play with your breast.
It was so much going on at once, you could forget about why he was really here..and that's exactly what he wanted.
••••• •••••
His ears perked as your noises grew. Fuck..a sound he'd miss. Your thighs started to clench, heck you were clenching around him.
"I got you baby.." He spoke soft. He continued pumping and curling in you, he could feel you coming closer.
His other hand continued to work at your breast, before slowly trailing down to your waist. He gave it a squeeze, before trailing down further to your hip.
"C-..close..oh my gosh.." You moaned, head thrown back against your pillow.
He continued to work you through your orgasm. Listening to your wet sounds, listening to the way his name fell from your lips.
Why.. why did this have to be the outcome of it all?
••••• •••••
Your hands gripped his locks harder. Hips bucking into his face as you came. His name fell from your lips.
He didn't stop. There was no break in his movement. He'd always been like this, over-stimulating you with his touch. You'd never complained..and after tonight, you'd wish you hated it.
Hated him.
But no, that'd never been a possibility. It'd never been a thought. No thoughts would ever come into mind especially when his tongue worked like that.
His slipped out, dripping with you. As your body ached for them, his tongue quickly came in. Lapping up all your juices.
As if he was desperately wanting to keep the taste forever. His tongue dipped inside you, swirling and teasing.
You moaned, not expecting it. But at this point, what could you expect from him?
He had licked you up clean..his lips started leaving soft, butterfly-like kisses. Trailing up your belly, between the valley of your breasts, up your neck and to those soft lips.
His tongue entangled with yours, one of yours hands leaving his hair to find his neck. Your tongues held there final dance as he separated.
His eyes trailed you, like a camera. Wanting to capture a memory. That's when it all came crashing back, he was no longer forever.
••••• •••••
He got out of the bed, wiping you down slowly. Even in a moment like this, he'd still do his best to give you some care. Even if now, it wasn't like his usual..but oh well, not like his behavior had been either.
He cleaned you up before he started putting his clothes back on. Then, he turned to you, putting the blanket on you.
He left a soft kiss on your forehead and left slowly. Walking backwards. Memorizing you for the last time. A tear slipping down his face as he closed your bedroom door. A soft thud, then came your front door.
••••• •••••
And there it was, you'd now lost a piece of yourself. It finally set in. Memories upon memories were now left in the air between you both. Questions stayed unanswered. The thing that hurt the most?..there came no "I love you" for the last time. Hence, they both knew. Their love would never stop. And maybe..
In another life, he would've been shameless with you.
