Panting, slick with sweat, Kook hauled her limp body upright against his chest. His hand tangled brutally in her hair, jerking her head back. "*Look at me,*" he commanded, voice low and ragged.

Tae’s eyes fluttered open, glazed but focused. He pulled her into a filthy, claiming kiss – tongues clashing, teeth scraping, the taste of salt and musk thick between them. When he finally broke away, breathing harshly, his palm cracked hard against her flushed ass.

"*Listen well,*" he hissed, fingers tightening in her hair. "*This cunt?*" He squeezed her slick thigh. "*This ass?*" He slapped her burning cheek again. "*Mine. You don’t spread them for janitors. You don’t bend for professors. You crawl, beg, and scream… for ME alone. Understood?*"

A shudder of pure bliss ran through Tae. "*Yes,*" she breathed, her hips instinctively grinding against his softening cock. "*Your cock… your rules…*"

She traced a trembling finger down his jawline. "*Say it again,*" she whispered, eyes dark with hunger. "*Say you own this slut.*"

Kook’s grip tightened. "*Every. Inch.*" His thumb brushed her swollen lower lip. "*And you'll wear my marks. Everywhere.*"

Tae moaned, arching into him. "*Mark me now… bite here…*" She tilted her neck, exposing the pulse point. "*Claim your property.*" Kook lowered his head, teeth scraping skin. Tae gasped, fingers clawing his shoulders. "*Harder…*" she pleaded. "*Make it bruise… make them all see who this whore belongs to!*"

Outside, distant footsteps echoed down the marble corridor. Closer. Someone humming. Tae froze, eyes widening slightly – not in fear, but exhilaration. "*Hear that?*" she breathed, a wicked smile spreading. "*The dean… he stops by Fridays… checks the offices…*"

Kook stiffened beneath her. "*Locked,*" he muttered, but his gaze flicked to the door. Tae grinned, shifting deliberately on his lap. His softened cock twitched against her wetness. "*Mmm… feels that?*" she murmured, grinding slowly. "*Getting hard again already…*" Her hand slid down, fingers wrapping around his thickening shaft. "*Imagine him walking in…*" she whispered, stroking him firmly. "*Finding his disciplined principal… balls-deep in his favorite campus slut…*"

Kook groaned, hips lifting involuntarily. "*Quiet,*" he ordered, but the command lacked force. The footsteps paused right outside the door. A soft rattle of the handle. Tae’s eyes locked on Kook’s, gleaming. "*Unlock it,*" she dared him, her thumb swirling his leaking tip. "*Show him who owns me…*"

The handle rattled again, more insistently. "*Principal Jungkook?*" Dean Yoon's muffled voice called. "*Lights still on. Everything alright?*"

Kook’s jaw clenched. Tae leaned closer, biting his earlobe sharply. "*Say yes,*" she hissed, her slick heat hovering just above his aching erection. "*Tell him you’re disciplining me… making me a good girl… then fuck his favorite slut silent while he listens…*"

Kook’s hand shot out, gripping the chair arm as Tae slowly, tortuously, impaled herself back onto his full length. A choked gasp escaped him. "*Fine!*" Kook barked towards the door, his voice strained. "*Occupied!*"

Below the desk’s edge, Tae began rocking slowly, rhythmically, her wetness making tiny, slick sounds. "*Mmm… occupied…*" she echoed breathlessly against his neck.

Kook gritted his teeth, forcing his voice steady. "*Just… finalizing Professor Kim’s mentorship evaluation. Intensely.*" Outside, a pause. Then a soft chuckle. "*Right, right. Dedication. Carry on.*" Footsteps retreated.

The tension drained from Kook’s shoulders. He sagged back into the leather, the adrenaline surge fading, replaced by bone-deep exhaustion.

Tae whimpered softly, still grinding slowly on him. "*Don’t stop…*" she pleaded. But Kook gently gripped her hips, halting her movements. He gazed at her – flushed skin, swollen lips, the deep bite mark darkening on her neck, her glossy pussy stretched snugly around him. A possessive satisfaction settled over him, deeper than rage.

His hand slid up her back, calloused fingers tracing the heated, crimson stripes across her ass. He landed one final, soft, almost tender smack. "*Enough,*" he murmured, his voice rough but low. "*You’ve screamed enough tonight.*"

With surprising gentleness, he lifted her off him, wincing slightly at the slick release. Setting her unsteadily on her feet, he stood, towering over her. He retrieved his ruined shirt, draping it loosely over her bare shoulders. His thumb brushed her bruised lower lip. "*Go home, Tae,*" he commanded, the authority back, laced now with undeniable ownership. "*Clean yourself.*" He delivered one last, firm pat to her well-spanked, marked ass – a caress ending his discipline. "*And be a good slut,*" he ordered, gazing intently into her dazed eyes. "*Save that greedy cunt... only for my cock.*"

Tae swayed, a slow, utterly submissive smile spreading across her face as she nodded, clutching his shirt tight. "*Yes, Principal,*" she breathed. "*Only yours… always.*"
