Work Text:
The darkness had collapsed around them seventeen minutes ago, dumping all three women back into the abandoned shopping district where they'd started. Yihak's canister was full—gloriously full, practically glowing with that A-grade golden essence she'd risked all their necks for.
Worth it, she thought, even as Seonghae's honey-colored eyes pinned her against the grimy tile wall of what used to be a cosmetics shop.
"Do you have any idea," Seonghae said, voice soft as silk, deadly as a garrotte, "what you almost cost us?"
Yihak's grin didn't falter. "But I didn't, did I? We all made it out, and we got the—"
"You broke formation." This from Nasol, whose sharp features were arranged in that particular expression of cold fury that made rookies piss themselves. "The entity nearly severed Seonghae's arm because you decided to go treasure hunting."
"Nearly being the operative word," Yihak shot back, though something in her stomach was starting to squirm. Nasol didn't usually back Seonghae up this directly. They had their whole complicated thing going on, sure, but when it came to work, the Assistant Manager typically handled discipline herself.
Unless.
Oh.
"Yihak-ssi." Seonghae stepped closer, and Yihak's back pressed harder against the cracked tiles. "I think you misunderstand your position here."
"I'm a Supervisor, same as you—"
"You're a junior Supervisor who just endangered her seniors on a joint operation." Seonghae's hand came up, fingers gentle as they traced the line of Yihak's jaw. The touch sent an electric shiver down her spine. "That requires correction, don't you think?"
Yihak's mouth had gone dry. "What kind of correction?"
Nasol moved then, flanking Yihak's other side. This close, she could smell the other woman's perfume—something expensive and cold. "The kind," Nasol murmured, "that ensures you learn your lesson."
"I—" Yihak swallowed hard. Her heart was hammering, but not from fear. "I don't—"
"You don't what?" Seonghae's thumb brushed over Yihak's lower lip. "Don't want this? We can leave right now if that's the case."
The out was clear. Explicit. Yihak could grab her canister and walk away, and they'd never speak of it again.
She didn't move.
"That's what I thought." Seonghae's smile was beatific, angelic even. It made Yihak's knees weak. "Nasol-unnie, I think we should take this somewhere more comfortable, don't you?"
"My apartment is closest," Nasol said. Her hand settled on Yihak's hip, possessive. "And more private."
Nasol's apartment was exactly what Yihak expected—sleek, minimalist, expensive. Floor-to-ceiling windows overlooked the Han River, currently painted in the oranges and pinks of sunset. The bedroom was all clean lines and cool grays, dominated by a bed that looked sinfully comfortable.
Yihak barely had time to take it in before Seonghae was turning her around, pressing her back against the closed bedroom door.
"Here's how this is going to work," Seonghae said, conversational, as if discussing mission parameters. "Nasol-unnie and I are going to teach you about consequences. About what happens when you put yourself—and us—at risk."
"And if I don't want to play along?" Yihak's defiance was automatic, even as heat pooled low in her belly.
"Then we stop." Seonghae's expression was utterly sincere. "Immediately. But something tells me you do want to play along, Yihak-ah."
Damn her for being right. Damn them both.
"Fine," Yihak said, lifting her chin. "Do your worst."
Nasol laughed, sharp and cold. "Oh, you're going to regret saying that."
Seonghae's hands were already working at the buttons of Yihak's blouse—the same efficient, graceful movements Nasol had described in her report from the Suraksan mission. "Strip," Seonghae ordered. "Slowly."
Yihak's hands trembled slightly as she obeyed, shrugging out of her blouse and letting it pool on the floor. Her skirt followed, then her bra. She hesitated at her underwear.
"Everything," Nasol said. She was perched on the edge of the bed now, still fully clothed, watching with those predatory eyes.
When Yihak was bare, Seonghae guided her to the bed with a gentle hand at the small of her back. "Lie down. Hands above your head."
Yihak complied, pulse racing. Seonghae produced a length of silk rope from somewhere—pre-planned, then—and bound Yihak's wrists to the headboard with expert efficiency.
"Test them," Seonghae instructed.
Yihak pulled experimentally. The knots held firm but didn't bite. She could probably get free if she really tried, but—
"Good." Seonghae sat on the edge of the bed, one hand trailing down Yihak's sternum, between her breasts, over her stomach. The touch was feather-light, maddening. "Now. Let's establish some rules."
"Rules," Yihak repeated, breathless.
"You don't get to come until I give you permission. Understood?"
Yihak's hips jerked involuntarily. "That's—"
"Understood?" Seonghae's hand stilled.
"Yes," Yihak gritted out. "Understood."
"Good girl."
The praise sent a shock of pleasure through Yihak's system, more potent than she'd expected. Seonghae's smile suggested she knew exactly what effect her words had.
"Nasol-unnie," Seonghae said, turning to the other woman. "I think you should help me. Don't you want to touch her?"
Nasol's eyes darkened. "Yes."
"Then undress for me."
Yihak watched, transfixed, as Nasol obeyed without hesitation. The Assistant Manager's usual sharp efficiency softened into something almost vulnerable as she stripped under Seonghae's approving gaze.
"Beautiful," Seonghae murmured. "Both of you. Now, Nasol-unnie—kiss her. Make her understand what she almost cost us today."
Nasol crawled onto the bed, settling beside Yihak. Her lips were soft when they met Yihak's, the kiss starting gentle before turning demanding, possessive. Yihak moaned into it, arching up, desperate for more contact.
"Ah-ah," Seonghae chided. "You don't get to be greedy, Yihak-ah. This is a punishment, remember?"
Nasol pulled back, and Yihak whimpered at the loss.
Seonghae was removing her own clothes now, methodical and unhurried. When she was down to just her underwear, she retrieved something from Nasol's nightstand—a harness and dildo that made Yihak's mouth go dry.
"I think," Seonghae said, fastening the harness around her hips, "that you need to learn how to follow orders. So here's what's going to happen." She settled onto the bed, back against the headboard, the toy jutting obscenely from between her thighs. "You're going to ride me. And while you do, you're going to make Nasol-unnie feel good. Do you understand?"
Yihak nodded frantically.
"Use your words."
"Yes," Yihak gasped. "Yes, I understand."
Seonghae untied Yihak's wrists, then guided her into position. "Go on, then. Show me you can follow simple instructions."
Yihak positioned herself over Seonghae's lap, sinking down slowly onto the toy with a broken moan. The stretch was perfect, overwhelming, exactly what she needed.
"Good," Seonghae praised, hands settling on Yihak's hips. "Now—Nasol-unnie, come here."
Nasol moved to kneel on the bed, positioning herself so Yihak could reach her. Up close like this, Yihak could see how affected the other woman already was, could see the flush painting her pale skin.
"Make her come," Seonghae ordered. "And don't you dare stop moving your hips."
Yihak ducked her head, pressing kisses to Nasol's inner thighs as she rocked in Seonghae's lap. The dual sensations—the toy filling her, the taste of Nasol on her tongue—were almost too much.
"That's it," Seonghae murmured, guiding Yihak's movements with firm hands. "Just like that. You're doing so well, Yihak-ah."
The praise made Yihak moan against Nasol's skin, and the Assistant Manager's hand tangled in her hair, pulling her closer. Yihak lost herself in the rhythm of it—the rocking of her hips, the flick of her tongue, the chorus of breathless sounds filling the room.
"She's close," Nasol gasped, and Yihak realized she was talking about her, not herself. "Seonghae-yah, she's—"
"I know." Seonghae's hands tightened on Yihak's hips, stilling her movements. "But she doesn't have permission yet, does she?"
Yihak whined, desperate, suspended on the knife's edge of pleasure.
"Please," she begged against Nasol's thigh. "Please, Seonghae-unnie, please—"
"Not yet," Seonghae said firmly. "Make Nasol-unnie come first. Prove you can put someone else first for once."
The rebuke stung, but it focused Yihak's attention. She redoubled her efforts, using everything she had—lips, tongue, fingers—until Nasol was crying out, trembling apart above her.
"Good girl," Seonghae praised, and started moving Yihak's hips again. "Such a good girl, both of you. Come now, Yihak-ah. You've earned it."
Permission granted, Yihak shattered, pleasure crashing through her in waves that left her gasping and boneless. Seonghae held her through it, murmuring praise and encouragement until the aftershocks faded.
When Yihak could think again, she found herself tucked between both women, Seonghae's fingers carding through her hair while Nasol traced idle patterns on her shoulder.
"So," Seonghae said, amused. "Have you learned your lesson?"
Yihak considered. The A-grade essence was still in her canister, worth a fortune. But the ache in her muscles, the satisfaction thrumming through her veins, the warmth of being held by these two dangerous, complicated women—
"Maybe I need a few more lessons," she admitted. "Just to be sure."
Nasol laughed, and Seonghae's smile was pleased and predatory all at once.
"Oh, Yihak-ah," Seonghae said. "I think that can be arranged."
