Chapter Text

The lecture hall is empty... almost. Glowing diagrams are still projected in the far right wall, the faint hum of the air conditioner filling the silence as Kuras sat on the edge of his desk, one leg crossed casually, textbook open at his side.
Ais stood infront of him.

He hadn't left his seat since the lesson started, and not after it ended until Kuras beckoned him closer. His composure cracked every time Kuras’s hand shifted up his thigh, ghosting over the bulge in his slacks.

"Relax," Kuras murmured, voice deceptively calm. "It’s just a quiz."

The first question was simple; "Name the bones of the forearm."

"U-ulna radius…" Ais managed, his voice catching as Kuras finally palmed him through the fabric.

"Good boy," Kuras praised, unbuttoning the slacks with deft fingers. "Where’s the origin point of the biceps brachii?"

Ais swallowed, throat working as Kuras slid his hand inside, wrapping warm fingers around his cock. "Scapula— glenoid fossa—"

"Mmhm. Correct." The first slow stroke had Ais gripping the edge of the desk behind him, jaw clenched tight.

Question after question came, each answered through grit teeth and stuttering breath as Kuras pumped him in a rhythm just shy of unbearable.

Then, Kuras leaned in, lips brushing Ais’s ear. "Insertion of the pectoralis major?"
Ais froze. His mind blanked. "Uh... I—"

"Wrong," Kuras’s voice darkened, hand squeezing at the base before easing the stroke to a torturous crawl. "That’s one."

Ais shuddered, thighs trembling. He got wrong the nxt question as well; and another orgasm denied.

By the time Kuras had racked up three, Ais was leaking down his hand, his chest heaving and eyes glassy.

"Please," he rasped, finally breaking. "Please let me—"

"Ah ah," Kuras cut him off with a squeeze just beneath the head that made Ais choke on his own breath. "Good boys don’t beg. They earn." He kissed the corner of Ais’s jaw, stroking him even slower. "So, tell me, my model student... where does the femoral artery run?"

Ais wasn’t sure how it had escalated this far. His clothes were a heap on the floor, his broad chest bare, goosebumps pebbling his skin from the icy blast of the vent above. His nipples were stiff peaks, so sensitive that every brush of Kuras’s hand made him jerk.

Kuras stood right behind Ais, chest firmly pressed against his bare back, trousers shoved just low enough to free his cock, his other hand wrapped tightly around Ais’s mercilessly.

"Sensitive, aren’t you?" Kuras murmured, running his thumb deliberately over a taut nipple, smirking when Ais gasped. "Are you even listening? If you’d been paying attention earlier, I wouldn’t have to do this." Ais bit down on a groan, hips twitching for friction that never came.

"Look at me," Kuras commanded. Ais’s dark eyes lifted, wide with frustration. "I thought you wanted to be good. Didn’t you?"

Ais’s breath hitched. "I do— fuck, I do, I’ll be good—"

"Then why do you keep failing me?"

Ais let out a choked sound, half-growl, half-plea. "Please— let me— let me make you feel good, I’ll be good, I swear it, I’ll take care of you, just—"

Kuras leaned down until his lips brushed Ais’s ear. "You? Take care of me? Look at you, falling apart just from my hand. You think you could last a second on top of me? You’d cum before I even let you in," he mocked.

The sharp creak of the lecture hall door broke the moment.

Both of them froze.

Standing at the threshold was Vere; hair immaculate, glasses glinting in the dim light.

For a beat, there was only silence. Vere’s gaze slid over the scene, when a bitter smile curved his lips.

"You never could keep your cock in your pants, Kuras, could you?"

Kuras didn’t even glance at him, instead he stroked Ais with just enough pressure to make him whine. "You’re interrupting a lesson."

Vere’s laugh was cruel. "Oh please. Look at him. He’s dripping on your hand and he's barely been touched," his eyes darkened as he scanned the naked man. "Enjoying this a little too much, aren't you?"

"Vere—" Ais tried interjecting, breathlessly, as Vere's hand slid up his thigh, nails dragging just enough to not surface blood.

"Should I assist? Or just take up the role of the... Finishing prize?"

Kuras’s grip on Ais tightened until he hissed. "Over my dead body."

Vere’s smirk widened. “Don’t tempt me. I just might. Besides… he clearly doesn’t mind." His hand travelled to Ais's chest, where he pinched a nipple.
Seeing Ais shiver, Vere ducked infront him. He pressed a light—almost tender—kiss against Ais’s chest, before he started sucking on the other one, clothed body grinding against the other's.

"P-please— gods," Ais gasped, reflexively arching into him. "I’ll be good, just don’t— don’t stop—"

"Then you clearly don't need me anymore," Kuras retracted his hand from Ais's dick, only for his wrist to be grabbed by him.

"No, wait—" In a flash, Kuras's thick leather belt had his wrists pinned together behind his back. "S-shit—"

Vere moved to grab Ais's jaw, demanding the attention back to him, only for Kuras to pull on the binded hands of his. Ais got unceremoniously spun around and fell on his knees as a dizzy spell hit him, finally coming face-to-face with Kuras's cock.

"I can work with that," Kuras said lowly, fisting Ais's hair and guiding his mouth to his dick.

Behind him, Vere laughed. "Same old Kuras. Always mistaking cruelty for control," his hand cracked down on Ais’s hip, dragging him back as he undid his own belt; wrapping it around his thighs to keep him spread just wide enough.

"You’re gonna tear him in half," Kuras bit out as Ais slowly took him in his mouth. Ever impatient, Kuras shoved his cock to the back of his throat. "That's it," Kuras muttered darkly, his voice a low growl as Ais gagged. "You wanted my attention? Then take it properly."

"Says who?" Vere’s grin was feral as he slammed forward, making Ais cry out even with his mouth full. "Your jealousy?"

"Pathetic," Vere sneered from behind, hips snapping forward hard enough to force Ais onto his toes. "Shivering like this. Can’t even stand up without leaning on one of us."

Ais tried to shake his head in protest, but Kuras's cock muffled it into a desperate, garbled sound.

"Shut your mouth," Kuras snarled he forced his dick deeper down the student’s throat. “You don’t get to talk."

Ais gagged, mascara streaked down his flushed cheeks in ragged black rivers, his lips swollen around Kuras’s cock, spit shining his chin. His eyes looked up at his professor, begging silently even as his throat spasmed around the intrusion.
He tried to pull back to catch a breath, but Kuras’s grip only tightened, holding him there firmly with his other against his shoulder to until his vision went white at the edges.

Behind him, Vere stilled; cock buried deep and refusing to move, a cruel smirk curving his lips.

"What’s wrong, Kuras? Thought you liked it when they suffer."

The older man’s golden eyes cut like knives. "You’re in my way."

Vere only chuckled, grinding slow circles of his hips just enough to make Ais cry out around Kuras’s length. "Funny, isn't it? One little pause and your boy here can't do a thing." He cooed. "Go on, Ais. Show him how useless you are without me moving you."

Kuras's jaw tightened. He wanted to tear Vere off him, but instead he leaned back, deliberate, and pressed his shoe against Ais's cock.

Heavy leather settled above the straining hardness between Ais’s legs, making the latter jerked at the contact, before he moved. Small, desperate rolls of his hips, grinding against the smooth surface, chasing friction like an animal in heat. Each rut left another smear of precum across Kuras’s shoe, meeting nothing but cold indifference from above.

"Pathetic," Kuras hissed.

Ais keened, until the sharp crack of Kuras’s palm landed across his cheek, forcing his head to the side. The sound echoed through the empty hall.

"No." Slowly, Kuras pulled free, leaving him gasping and drooling, lips bruised. He lifted his shoe, now slick with Ais’s mess, and pressed it to his lips. "Clean it."

Ais obeyed without thought, tongue reverently licking up everything as Kuras watched with disdainful satisfaction. "Good," he petter Ais's hair. "I have another lecture after this..."

Vere laughed from behind, shoving into him again just as his tongue lapped at the buckle. "You really do train them like dogs, don't you?"

Kuras smirked down, eyes never Ais. "No; dogs have more dignity."

Chapter Text

"Could you not breathe down my neck?" Mhin hissed as Leander brushed past them in the empty corridor. "Why the fuck are you here?"

Leander only smiled that infuriating smile, holding up his satchel. "Notebook. You?"

"Jacket," Mhin muttered, tugging their hoodie tighter around their waist. "Not that it’s your business."

A low, gutteral moan echoed faintly through the corridor, making them exchange glances. They reached the lecture hall at the same time, still muttering at each other when Mhin shoved the door open— the air left their lungs.

Ais's wrists were bound behind his back and raw from the tugging, mascara running down his flushed cheeks as he licked obediently at Kuras’s polished shoe. Vere was still inside him, lips twisting in a smirk.

The podium's mic was still on; "Dogs have more dignity," Kuras snarled. "You’ll clean it until I’m satisfied."

Mhin’s stomach flipped, heat rushing down so fast they swayed on their feet. "Holy shit..."

Beside them, Leander leaned casually against the doorframe, eyes glittering with interest. "Well, that’s one way to spend office hours."

Mhin shot him a sharp look, but couldn’t tear their eyes away. Ais whined, the sound carrying crystal-clear through the speakers.

"Close the door," Mhin finally hissed under their breath, throat dry.

"You close it," Leander countered.

Mhin’s nails dug crescents into their palms, as they somehow found it in them to grab the handle and hide the sight from view.

In the hallway, both them and Leander just stood there.

Mhin scrubbed a hand down their face, ears hot. "What the fuck."

Leander was smiling. Of course he was smiling. "What the fuck indeed."

"Don’t," Mhin snapped, pointing a finger at him. "Don’t start. We didn’t see anything, we didn’t hear anything, we’re forgetting it—"

"You’re trembling," Leander interrupted smoothly, eyes flicking down with a grin. "And you’re turned on."

Mhin froze, fury rushing up their throat. "Fuck you."

Leander only stepped closer, that infuriating warmth radiating off him, leaning until his breath ghosted Mhin’s ear. "Gladly. Can do it right here, if ya want."

Mhin’s knees nearly buckled. "You’re an ass."

Leander’s grin softened, hunger flickering in his eyes. "And yet—"

He went to grab Mhin, but they were faster; they grabbed him by the collar and shoved him against the wall, teeth bared.

"—you're thinking about it."

"You’re such a fucking—" Leander's mouth clashed against theirs before they could finish.

Their breath caught as Leander’s hand slid down to cup the sharp line of their hip and truned them around, pinning them against the wall. Mhin tried pushing him away, but their hips betrayed them, grinding against the thigh Leander slid between theirs.

Mhin's hands were at his belt, yanking it open like they hated the thing, shoving them down just far enough for Leander’s cock to spring free into their palm.

"Thought you didn’t want this," Leander murmured, voice ragged.

He caught their mouth again, hungrier this time, one hand sliding lower. His palm cupped between their legs—where his thigh had just left—and he groaned. "Fuck, you’re perfect," he fumbled at their waistband.

"Get on with it, or I'm leaving," Mhin panted, squeezing his cock in their hand.

Leander immediately shoved their pants down, pulling them closer by the waist and lining himself up. Mhin’s nails dug into his shoulders when he pressed forward, stretching them open inch by inch.

Leander’s breath hitched, his forehead dropping to the wall beside theirs. "Gods, you’re—tight..."

Mhin bit down on his neck to stifle a groan, clenching around him in a way that made his vision blur.

For a moment, neither moved.

Then, Mhin shifted their hips back against him impatiently. "Stop holding back," they muttered.

The first grind wasn’t enough; neither was the second. Mhin’s teeth scraped along Leander’s jaw, their hips snapping forward again and again. The sound of skin against skin echoed down the empty hall, as well as Leander's sounds tearing out of him.

"Mm, you feel so good," Leander practically purred against them. "Will you beg for me?"

"Beg?" Mhin's head tipped back against the wall, breath ragged, but their eyes never left his face. "You think you're worth begging for?"

Leander chuckled, thrusting harder, one hand cupping their jaw to force their gaze forward. “Oh, come on."

In retaliation, Mhin leander in and pulled his hair. "Talk all you want," they murmured, their voice lethal. “But you'll come when I want. Not before, not after."

Leander’s eyes rolled back, hips stuttering helplessly despite his earlier swagger. "Fuck—you’re—ah—"

"Yeah, that’s what I thought."

Mhin's gaze darkened, looking down on him like he was prey. "You should've seen your face in there," they nodded toward the hall door. "Watching Ais lick Kuras’s shoe like that. Thought you’d melt into the floor."

Leander gave them a pathetic whimper, burying his face against their throat.

"Bet you'd lick my boots if I asked you to. Wouldn't you, you slut?"

"Y-Yes, y— God—"

"It's only me here," Mhin slid a hand under his shirt, finding ane pinching his nipples so hard, Leander arched his back into them. "And I expect you to treat me as such."

Leander's dick twitched inside of them, and they let out an unamused huff. "Say it. Tell me what you’d do for me."

Leander’s breath caught, desperate. "Anything—fuck, anything, I’ll—" He broke on a moan.

"You’ll what?" Mhin pressed, pinching his nipple again and again, until he responded.

Leander’s eyes squeezed shut, head falling against their shoulder. "I’ll—I’ll lick your boots, I’ll worship you, I’ll let you use me however you want, just— just please let me cun."

"You're such a whore," their nails ranked down his chest. "Fucking's all you're good for."

Leander gasped, clinging to them like he was drowning, his rhythm flattering and body already shuddering on the edge.

Suddenly, his hand slid down to stroke Mhin where they needed it most. "Don’t—" they gasped, trying to shove it away. "Don’t—ah—"

Mhin came hard, throwing their head against the wall, clenching so tight around Leander that he choked on his breath and spilled inside them.

For a moment, they just clung there, pressed together.

"What did I tell you, huh?" Mhin’s glare could have gutted him. "You don't get to touch me like that."

Leander whimpered, lips brushing against their collarbone. "I just wanted to make you feel good—"

“That’s not your call.” Mhin shoved him away.

Leander’s eyes found theirs, glassy, chest still heaving... But for another reason now.

He nodded, frantic, swallowing around the lump in his throat. "...m’sorry."

Mhin leaned in, catching his jaw in one hand, forcing him to meet their gaze. "You’re going to regret it. I’ll make sure of it; make sure you know exactly where you belong." Their thumb brushed his lower lip, almost gentle before digging in hard enough to leave a mark.

Leander’s breath hitched, torn between dread and need, already stirring beneath the shame of it. "…yes."

"Say it," Mhin snarled.

"I’m a whore. I’m just your slut. I'm— please—"

"Get on your knees. You came watching someone else get used like trash, and now you want me to treat you the same? If you’re so desperate for it, you can start by using that mouth to recreate what you saw back there."
