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.
