Lips #10 (Red Velvet's Irene, Seulgi, Joy, Yeri)

You are on your way back from the trainee practice room, sweat still cooling on your skin, a towel slung over your shoulder. It has been a long evening of drills, and all you want now is to find an empty studio to sit in for a few minutes before heading back to the dorms. The hallways are quiet this late, most people have gone home or are in their own corners of the building. As you pass one of the smaller practice rooms, you catch faint voices coming from inside. They are low, but with a certain… tone that makes you pause. Curiosity gets the better of you. You step closer, pressing your ear to the door just enough to hear clearly.

“…I just… I don’t want to be bad at it.”

A voice you recognize as Yeri’s carries a touch of embarrassment in her tone. You’ve met her and her members briefly here and there in the hallways and so on. But you never had a proper conversation with any of them.

“You’re overthinking it.”

That’s Seulgi’s voice.

“If you relax and listen to the other person’s reactions, you’ll know exactly what to do.”

There is the faint scrape of something being picked up, and Yeri’s voice again.

“You really brought this… to the company?”

“Why not?”

Seulgi chuckles.

“You said you wanted to learn. This is as good a time as any. You said you started seeing someone, right? You want to surprise him, don’t you?”

You frown slightly, confused. And then it hits you what she might be talking about.

“I do.”

Yeri admits quietly.

“I just… don’t want him to think I’m inexperienced.”

“Then let’s practice. If you can handle this, the real thing will be even easier.”

There is a rustle of movement, followed by the low, plastic sound of something being placed on the table. Your curiosity burns hotter. Without thinking, you lean just enough to push the door open a crack.

Yeri is sitting cross-legged on the floor, facing Seulgi. In Seulgi’s hand is a realistic looking dildo. Not huge, but clearly… not just a random prop. Yeri’s eyes dart to it, nervous but determined, while Seulgi sits with her usual relaxed confidence, offering calm instructions. You mean to step back, to quietly leave before they notice, but your shoe squeaks against the polished floor. Both heads turn toward the door. Yeri’s eyes widen instantly in shock. Seulgi, on the other hand, simply tilts her head, her lips curling into a slow smile.

“Well, looks like we’ve got ourselves a volunteer.”

She says, her voice low but carrying across the room,

You freeze in the doorway, torn between backing out immediately or pretending you haven’t seen anything. Before you can decide, Seulgi sets the toy down on the table beside her and gives you a little wave to come closer.

“Don’t just stand there. You’ve already seen enough to know what’s going on.”

Yeri’s cheeks flush deep red.

“Unnie, you can’t just-”

“Why not?”

Seulgi interrupts smoothly.

“He’s right here, and he’s real. Much better than this.”

She taps the toy lightly with her finger. Her eyes flicker back to you.

“You don’t mind helping, do you?”

Your mouth opens, but no sound comes out. The whole situation is absurd. You’ve just been looking for a quiet room, and now one of your seniors is offering… this.

Seulgi stands up and walks toward you. She stops just in front of you, her head tilting slightly as she studies your face. You wonder if she even recognizes you. You saw her in the cafeteria yesterday.

“I’ll take that silence as a yes.”

Before you know it, you are sitting on the padded bench along the wall, Yeri kneeling awkwardly in front of you, still looking uncertain. Seulgi crouches beside her, one hand resting reassuringly on Yeri’s shoulder.

“Alright.”

Seulgi begins, her tone slipping into a calm, instructive rhythm.

“First thing: Don’t rush. Make him feel like you’re interested, even if you’re nervous. It’s all in the pace.”

Yeri glances up at you, her eyes meeting yours for a moment before she reaches forward. Her touch is tentative at first, fingers curling around your cock like she is afraid she might do it wrong. Seulgi’s hand guides hers gently, adjusting her grip.

“Better. Now use your mouth. Start slow, just the tip, and listen for his reaction.”

You swallow hard as Yeri leans in, her lips parting hesitantly. The warmth of her mouth is almost shocking after the surreal lead up, and you exhale slowly without meaning to.

Seulgi catches it.

“See? That’s a good sign. Keep that pace, and don’t forget your tongue.”

As Yeri follows her instructions, Seulgi’s voice stays low, coaching her through each movement. At times, she’d place her own hand over Yeri’s, guiding the rhythm. Other times, she’d brush Yeri’s hair back so you could see her fully, her eyes glancing up at you with that mix of nervousness and determination.

“You’re doing better already.”

Seulgi praises. Then she looks at you, her smirk returning

“He seems to think so too.”

Yeri’s lips move slowly over you, her tongue flicking in quick, uncertain motions until Seulgi’s voice cuts in again.

“Not just at the tip, Yerim. Flatten your tongue a little, let it drag along the underside when you come up. There… like that.”

You feel the change instantly. Her mouth feels warmer, smoother, and the subtle change in pressure makes your breath catch. Seulgi notices your reaction right away, the corner of her mouth lifting in approval.

“See? That’s better.”

Her hand is still resting lightly on Yeri’s head.

“Now take a little more each time. Don’t force it. Just relax your jaw and let him guide you in.”

Yeri hums in acknowledgment, the vibration adding another layer of sensation as she eases forward, taking you deeper. She pulls back with a quiet pop of her lips, glancing up at you as if to check if she is doing it right.

“Don’t stop to look up at him.”

Seulgi brushes Yeri’s hair behind her ear.

“You’ll know you’re doing it right if he can’t stop looking at you.”

And you can’t. Your gaze is locked on her. The sight of one of your seniors kneeling in front of you, being coached by another is truly captivating. Seulgi shifts then, moving behind Yeri and leaning forward so her chin is over Yeri’s shoulder. Her hand slides down to wrap around the base of your length.

“Use your hand at the same time. Twist a little, like this. It’ll make it feel fuller for him.”

Yeri mirrors the movement with her own hand as Seulgi guides her, and the combination of their touches sends a shiver up your spine.

“That’s it.”

Seulgi encourages.

“Now… try going down again. Don’t rush up right away. Let him feel how warm you are.”

Yeri obeys, her lips sealing around you as she takes you deeper, her tongue pressing gently along the length. Her breathing grows heavier, and you realize she is concentrating hard, following every bit of Seulgi’s guidance. Seulgi’s hand doesn’t leave your base. She keeps the steady twist going, syncing with Yeri’s rhythm. “You’re close, aren’t you?”

She asks, her tone is teasing. But she is sure because your cock is starting to twitch inside her hand. You nod, your fingers curling against the edge of the bench.

“Good. Then, Yeri… keep that pace. Don’t let up until he’s finished.”.

But after a few strokes, Seulgi’s eyes flicker up to you and then back to Yeri.

“Actually… let me show you something.”

She gives Yeri’s shoulder a light squeeze, and Yeri leans back. Seulgi dips forward and takes you into her mouth herself. Her lips seal around you in a way that feels instantly different. It’s smoother, more confident, her tongue working in long, satisfying strokes. Yeri’s eyes widened a little.

“You make it look so easy, unnie…”

“It’s all about control.”

Seulgi says after pulling back with a faint glisten on her lips.

“You don’t have to rush. Watch how I use my tongue and my hand together.”

She takes your cock into her mouth again, her hand twisting slowly at the base, her tongue pressing in just the right spots. The sensation has your hips twitching. After a few more seconds, Seulgi eases back and nods for Yeri to take over.

“Now try it again. Match my pace. Don’t just move up and down. Feel it.”

Yeri leans in, more determined this time. Her mouth warmer and wetter after seeing Seulgi’s example. Her strokes are steadier now, her hand syncing with the movement of her lips. Every few moments, Seulgi offers a small correction, a shift in her grip, a reminder to keep her tongue flat, a nudge to take you a little deeper.

You could feel your climax building fast now, the combination of Seulgi’s guidance and Yeri’s effort making it impossible to hold out much longer.

“I’m… close.”

Yeri freezes for a fraction of a second, unsure, pulling her mouth back slightly.

“Uh…what should I…”

Seulgi’s hand closes around you, taking over before the moment slips.

“If you want to give a perfect blowjob, you have to be able to take a facial too.”

Yeri’s blush deepens, but she doesn’t move away. She sits back on her knees, looking up at you, her lips parted slightly.

“That’s it.”

Seulgi encourages, her strokes quickening.

“Keep your eyes on him. Let him see you take it.”

The combination of Seulgi’s words, her hand, and Yeri’s gaze pushes you over the edge. You groan, your hips jerking forward as you cum. Hot streaks paint across Yeri’s cheek and lips. She blinks at the first hit, then stays still just like Seulgi told her, letting every drop land on her face. When it is over, Seulgi releases you and gives Yeri a small, satisfied smile.

“Perfect. Now he’ll never forget it. And neither will you.”

Yeri wipes her cheek slowly, still catching her breath. You are in the same state. Head spinning, vision a little fuzzy, half leaning back against the bench, trying to process that your seniors had just done this with you in the middle of the company building. Yeri sits frozen for a moment, your load dripping slowly down her cheek toward her jaw. Seulgi’s eyes linger on the mess with a faint smirk before she leans in closer.

“Don’t waste it.”

To your shock, her tongue traces along Yeri’s cheek in one slow lick. Yeri’s breath catches, her eyes darting sideways at the sudden intimacy. Seulgi catches another drop at the corner of Yeri’s mouth, then presses her lips lightly to hers in a quick kiss.

“See? Nothing to be nervous about.”

You can barely form a coherent thought as they both glance back at you before they stand and begin tidying themselves like nothing unusual had just happened.

You leave the practice room in a daze, the sounds and sensations replaying in your head like a loop you couldn’t turn off. The hallway feels empty as you wander without any real destination. Before you realize it, you are standing in the doorway of one of the smaller recording studios. The room is empty. You step inside, shutting the door behind you, and sink onto the couch in the corner. Your legs feel weak. Your chest is still rising and falling with shallow breaths. It is almost impossible to believe what had just happened. Seulgi and Yeri, both your seniors, two members of Red Velvet, taking turns on you, touching you, looking at you like that, sucking your cock.

The more you think about it, the more your body reacts. You lean back into the couch, your hand moving to your lap almost on its own. At first you tell yourself you’d just… take a moment. But the images in your head are too vivid. Yeri’s nervous eyes looking up at you, Seulgi’s hand around you, the sight of your cum painting Yeri’s face. You slip your hand inside your pants, your grip firm as you stroke yourself slowly, eyes closing as you replay every detail. Your breathing grows heavier, your hips shifting against your own touch. You are so deep in it that you don’t hear the faint sound of the door opening until it clicks shut again. Your eyes snap open. Standing in front of you are Irene and Joy.

Irene’s brows furrow immediately.

“What the hell are you doing?”

She looks annoyed and angry. But Joy… Joy’s eyes don’t leave your lap. Irene’s arms fold across her chest as she steps further into the room.
“Unbelievable. In the middle of the building? Have you completely lost your mind?”

You open your mouth to respond, but Joy is barely listening. Her gaze stays locked on your lap, her lips parting just slightly as she tilts her head to get a better look.

“Joy.”

Irene snaps without even turning toward her.

“Stop staring.”

Joy doesn’t move.

“I can’t help it.”

She murmurs with a light smile playing around her lips. Her eyes still fixed on your clothed cock

“He looks… hard.”

Your pulse kicks up at the bluntness in her voice. Irene turns, shooting her a glare.

“You have a boyfriend. Remember?”

Joy finally tears her gaze away from you to look at Irene, her smile widening.

“He’s not here right now. He doesn’t have to know.”

Irene’s frown deepens.

“That’s not the point-”

“That’s exactly the point.”

Joy interrupts, stepping closer to you, her voice dropping into a more teasing tone

“You should try it, unnie. Wouldn’t it be good for you to let loose once in a while?”

Irene lets out a quiet scoff, but her eyes flicker to you briefly before darting away again. Joy catches it immediately and grins. Her hand brushes over your thigh without warning.

“See?” He’s right here, and he wants it. Don’t tell me you don’t.”

Irene’s gaze flickers down toward your lap again, almost involuntarily, but she quickly looks away.

“He’s too young for me.”

She says flatly, though there is the faintest edge in her voice that doesn’t sound entirely convinced. You’re just watching both of them, not daring to say a word.

Joy crouches a little in front of you, her hand boldly sliding up your thigh.

“Too young?”

She repeats, her tone dripping with mock innocence. Her fingers brush over your hardness through the fabric, and she smiles when she feels you twitch under her touch.

“Feels to me like he’s big enough for both of us, unnie.”

“Joy-”

Irene starts, but her voice falters when Joy’s hand slides higher, her palm now stroking up and down your length with slow pressure. You let out a shaky breath, the mix of Irene’s cold, distant posture and Joy’s shameless touch making your head spin. Joy glances back over her shoulder, catching Irene’s expression.

“You’re telling me you’ve never wondered what our trainees are packing?”
Joy teases then gives you a wink as if she’s promising you that she’ll convince Irene.

“All those late nights at the company and you’ve never thought about just taking what you want?”

Irene’s lips press into a thin line, but she doesn’t move to stop her. Joy turns her attention back to you, her hand squeezing just enough to make you exhale sharply.

“See? He’s not a boy, unnie. He’s a man. And he’s sitting right here, just waiting for us.”

Joy gives you one last lingering stroke through your pants before tugging them down just enough to free your cock. Her eyes light up instantly, lips curling into an appreciative smile.

“Mmm… told you. Big enough for both of us.”

“Joy.”

Irene warns again, but her voice has lost some of its earlier bite. Joy ignores her, leaning in until her breath ghosts over your tip.

“You’ve been touching yourself thinking about someone, haven’t you?”

Her eyes lock on yours.

“Was it someone we know? …Or are you thinking about us now?”

Before you can answer, her lips close around you, warm and soft, her tongue swirling lazily as she takes the first few inches. Her free hand rests on your thigh while the other wraps around your base, stroking slowly. Your head rolls back, a quiet groan slipping out. Joy pulled off just long enough to glance at Irene again, dragging her tongue along the underside of your length before she speaks.

“You’re seriously gonna just stand there and watch?”

Irene’s arms stay folded, but her eyes are locked on Joy’s mouth around you.

“You’re out of control.”

You notice how Irnee’s voice has softened. Joy smirks, then takes you deeper, humming low in her throat.

“Mmh… maybe. But you’re still here, unnie.”

The words seem to hang in the air between them. Irene shifts her weight from one foot to the other, her gaze flicking from Joy’s mouth to your face and back again.

“Come on.”

Joy said between licks, her tone playful but urging.

“Just one touch. See what you’re missing.”

Irene hesitates. Then finally steps closer. She stops just short of kneeling, her shadow falling over you as she leans down until her face is level with yours. Her eyes are sharp, her voice low and cold.

“If you tell anyone about this, you’re going to be in serious trouble. Understand?”

You swallow hard and nod. Her ice cold voice has goosebumps form on your skin. But before the weight of her warning can fully settle, Joy’s voice cuts in.

“Or… if he doesn’t say anything to anyone,”

She says with a grin, giving you a slow, teasing stroke.

“we might as well make this a regular thing.”

Irene shoots her a look, but Joy just laughs softly.

“Oh, come on, unnie. You’re already here. Why not enjoy it?”

Irene rolls her eyes, but you can see a tiny shift in her expression. One that means she is done fighting herself. With a quiet sigh, she lowers herself to her knees beside Joy. Joy’s smirk widens. Then she gives you another wink.

“Told you she’d come around.”

Irene’s hand wraps itself around your base, testing your weight with a firm squeeze before glancing at Joy.

“You’re too sloppy. Move over.”

Joy just giggles and shifts slightly, her mouth wrapping around you again as Irene’s hand guides her pace. The contrast between them, Joy’s playful enthusiasm and Irene’s controlled precision, make your head spin. Joy’s lips slide over you with a slow, steady rhythm, her tongue swirling each time she comes up. Irene’s hand stays wrapped firmly around your base, stroking in practiced pulls that match Joy’s pace perfectly. From your angle, you can see Irene’s gaze linger on where Joy’s lips meet your skin, and her breathing grows just a touch heavier. She squeezes you a little harder, her strokes picking up ever so slightly. The look on her face isn’t just curiosity anymore. Irene is growing impatient. Finally, Joy pulls back with a wet pop, licking her lips.

“Wanna take over, unnie?”

Her tone is still teasing. Irene gives her a sharp look, muttering under her breath.

“Slut.”

Joy just laughs and moves aside, her hand trailing down your thigh

“Guilty.”

Irene doesn’t waste time. She leans in and takes your cock into her mouth in one smooth motion, her tongue flat and warm against you. The sudden difference in skill is almost overwhelming. Her movements are precise, her suction strong. Your breath hitches. She feels so good around your length. Joy notices and grins, leaning close to your ear.

“She’s amazing, right? Always acts so perfect… but look at her now.”

She traces her finger along your chest, her other hand playing with the hem of her shirt as if she’s considering exposing more of you.

“Bet you never thought you’d have her on her knees.”

Irene ignores her, focusing entirely on you. The mix of Joy’s shameless commentary and Irene’s expert mouth has you gripping the edge of the couch, unsure how much longer you can hold out. Joy stays close to your ear, her voice a low purr while Irene’s mouth works your dick.
“Mmm… you like that, don’t you?”

She whispers, dragging her nails lightly down your chest.

“If you want, I could give you throat training lessons every week.”

Your breath catches, and she grins.

“For my throat, of course. Not yours.”

Irene’s eyes flicker up at Joy briefly but she doesn’t break her rhythm. Her lips glide down your length with a perfect seal before pulling back just enough to let her tongue swirl over the tip. Joy tilts her head, watching.

“Look at her. All serious… no fun. I’d have you moaning by now if I was down there.”

That earns her a quick, annoyed look from Irene, who finally pulls back just enough to speak.

“Then make yourself useful instead of running your mouth.”

Joy’s smile widens like she’s been waiting for that all along.

“Gladly.”

She slides down in front of you again, nudging Irene slightly aside. The shift is immediate. Irene’s precise, controlled style gives way to Joy’s playful, messy enthusiasm. She takes you deep without warning, humming around you, her hands gripping your thighs while she bobs her head with an eager rhythm. The contrast is making you dizzy. The way Irene felt like she was in total control of your body versus the way Joy makes you feel like she wants to drain every last drop from you. And now, with Irene kneeling beside her, watching you with that cool, unreadable stare while Joy’s mouth moves along every inch of your cock, the tension between them makes the whole thing even more surreal. Joy pulls back just enough to let the cool air hit your wet cock, her lips glistening. She gives the tip a slow lick before smirking up at Irene.
“You know, unnie… you should join me for some throat lessons too.”

Irene rolls her eyes.

“Especially at your age. Gotta take care of your body.”

Now Irene’s jaw tightens. Her expression stays otherwise unreadable. Joy grins wider, circling her tongue lazily around you.

“I’m serious. A few weeks with me and his cock and you’ll feel ten years younger-”

That’s it. Irene’s hand shoots out, fingers tangling in Joy’s hair as she pushes her head firmly back down onto you. Joy lets out a muffled sound, but Irene doesn’t stop. She begins to not just guide her, but use her. She moves Joy’s head up and down in long, deep strokes, her grip firm in her orange hair. Your head falls back against the couch, a groan slipping from your throat. The difference is incredible. Joy’s mouth is still warm and eager, but now every motion has Irene’s precision behind it. The sloppy, wet heat of Joy combined with the exact pacing Irene imposes makes it feel like her mouth has turned into the perfect toy in Irene’s hands.

Joy doesn’t resist. In fact, she hums around you like she is enjoying being used. Her fingers curl into your thighs for balance while Irene keeps her moving at just the right speed to push you toward the edge. Irene’s cold gaze flickers up to meet yours, holding it for a moment as she shoves Joy down deep again

“Better?”

She asks flatly, as if she doesn’t even care. As if she’s just doing this to shut Joy up. You can only manage a breathless nod, your whole body tensing under their combined touch. Irene keeps Joy’s head moving in perfect rhythm, her eyes locked on you. The combination of her control and Joy’s wet, eager mouth has you teetering on the edge in no time. Your breaths grow quicker, your hips twitch. Irene notices instantly.

“You’re close.”

Just when you think she is going to make you finish right there, Irene pulls Joy off your lap abruptly, still gripping your length in her hand. Joy gasps for air, her lips red and slick.

“Hey-”

But Irene ignores her, her hand stroking you with quick, practiced pulls. She leans in without breaking her gaze from yours and takes your cock into her mouth herself. Her tongue presses hard underneath as she works you over the edge. That final shift is too much. You groan low, your climax hitting fast and hard. Irene takes it all without flinching, her cheeks bulging as she takes your entire load. Your head spins and you almost grab a fistful of Irene’s hair.

Joy sits back on her heels, still catching her breath, a mock pout on her lips.

“Seriously? You just-”

Irene cuts her off. She leans toward Joy, then suddenly parts her lips and spits your warm cum across Joy’s face. Her saliva and your load paint the younger woman’s features. Joy is frozen, eyes and mouth wide open in shock. You aren’t sure which of you is more stunned. You catch a few drops of the mixture drop off Joy’s upper lip and fall into her mouth. Irene just sits back calmly, a faint smirk playing on her lips.

“What? Isn’t that exactly what you wanted?”

Joy blinks once. Then twice. After she overcomes her surprise she swipes a finger along her cheek before sucking it clean.

“Seems like it. Delicious.”

Joy grins when her phone suddenly buzzes in her pocket. She pulls it out, glances at the screen and her smile turns sly.
“It’s my boyfriend.”

She says with a little laugh, the mix of your cum and Irene’s spit still glistening on her face. Without even wiping it off, she answers.

“Hey, babe… mm, yeah, I’m still at the company.”

She says casually, winking at you as she scoops up another globe of cum and spit.

“I’ll see you later.”

She hangs up, gives you another teasing smile and turns towards the door.

Irene lingers for a moment longer, her arms folding loosely as she looks at you.

“Be here again next week.”

As she reaches for the door, she glanced back one last time, the faintest teasing curve at the corner of her lips.

“Hope you debut soon.”

She slips out, the door clicking shut behind her.

You sit there for a long moment in the quiet, still trying to process what the hell just happened.
