“Please see me after class if you have any questions about your grades,” Bum’s reedy voice called over the end of class bell. His students didn’t seem to pay attention at all, standing and chatting as they filed out, paying him no mind. It was all the same to Bum. He rather disliked talking to whiny students after class anyway. It never went well.
He sighed heavily as he packed up his things. Why was he doing this? Why was he here? Doubt infested his mind, growing deeper every day. The truth was staring him in the face. He wasn’t meant to be a professor.
Bum leaned his palms on the front table of the lecture hall, closing his eyes and taking slow breaths. The students all hated him. His lectures were boring and difficult to understand. Who cared about biology anyway? Maybe he should try a lab class, if the university would let him--
“Excuse me, professor?”
The deep voice startled Bum from his thoughts. He jumped and stepped back, staring at the intimidating man before him. He recognized the blonde instantly from his class. Oh Sangwoo. He was one of the most popular students in his grade, always flanked by the prettiest girls and equally handsome boys. He had a gravity to him, one that even Bum felt drawn to. He always felt awkward when they made eye-contact during class, his cheeks flushing with warmth from the intense stare that Sangwoo always gave him.
“C-can I help you Mr. Oh?” Bum managed to stutter, remembering where they were.
Sangwoo pursed his lips, glancing toward the desks. “Maybe. I think there might be a mistake on the latest paper you graded for us.”
Bum bit his lip. “You think so? I could take a look at it again for you.”
Sangwoo gave him a smile. “Can you look at it right now?”
“Oh. Ah, sure.” Bum didn’t have a class after this one, and no other class came in for another hour after his, so he certainly had time.
Sangwoo placed his backpack on the table and opened it up, digging through it for a moment. Bum couldn’t help but stare at the way his large hands moved. He was very careful with his movements, not sloppy like other young men of his stature.
“Ta da~” he found the paper and drew it out with a flourish, slapping it on the table in front of Bum.
Bum licked his lips and peered at it, spotting his sloppy handwriting at the top. The red ink scrawled, 4/25. Right. Sangwoo hadn’t done well on this paper. Bum took a slow breath and flipped through the pages. He’d written out why the answers were wrong, and skimming over it, he could see his reasoning was sound.
He shook his head. “I’m sorry Mr. Oh, but I have to stand by this grade. If you’d like to further discuss your answers we can…”
Bum trailed off when Sangwoo’s large hand thumped down on top of the paper. He looked up at him, realizing he was much closer. Too close. They were almost touching. Bum could feel Sangwoo’s body heat, and it made that forbidden heat rise through his own body again.
Sangwoo was still smiling. “Professor Yoon, I’m sure there’s an arrangement we can make. I can’t have a grade like this bringing me down. You know that, right?”
Bum swallowed past his suddenly dry throat. The way Sangwoo was talking set him on edge. “Mr. Oh, there will be plenty more assignments that you can--”
“You’re not understanding me, Professor,” Sangwoo interrupted him. He moved, slowly rounding fully on Bum. Facing each other, with Bum’s back against the edge of the table, Sangwoo leaned in, placing both palms flat on the table, his arms trapping Bum on either side. Bum’s heart jumped into his throat as he stared up at Sangwoo. Fuck, he was tall. He was tall, and broad, and strong, strong enough to take what he wanted…
“Th-this is inappropriate, Mr. Oh,” Bum whispered.
Sangwoo cocked an eyebrow. “What’s inappropriate is the way you look at me every class period,” he murmured.
Bum’s eyes widened. “I don’t--ahh!”
He cut off when Sangwoo pressed in tight, pushing their hips flush together. Bum tried to arch back more, barely able to keep his footing. His face flushed and he turned away from Sangwoo to try and hide it. But he couldn’t hide everything.
Sangwoo chuckled darkly. “As I thought,” he murmured, slowly grinding his hips against Bum’s erection. Bum trembled, terrified to be found out, but what had his heart beating like a caged bird was that Sangwoo was hard too. “To think, Professor Yoon is a pervert,” Sangwoo continued, tsking.
Bum grit his teeth, eyes hidden behind his curtain of black hair. “I’m n-not--mmf!”
Sangwoo cut him off again by swooping down and crushing their mouths together. His large hand grasped Bum’s jaw, keeping him in place. Bum shivered, automatically opening his mouth in response, letting Sangwoo in. He could feel the strength in Sangwoo’s grip. He could bruise him so easily. The thought sent another shiver through him, and a jolt of pleasure right down to his groin.
Sangwoo took full advantage of Bum’s offered mouth, forcing the small man to tip his head back more as his tongue dove into the wet cavern. He ran his tongue over the roof of his mouth and along the insides of his cheeks, kissing him deeper than anyone ever had. Bum’s eyes fluttered. This was wrong. This was wrong . Sangwoo was his student. He’d be fired and maybe even charged with molestation if anyone saw, and yet…
And yet, the sinful urge to keep going, to let Sangwoo have his way, gripped Bum’s wavering resolve. He couldn’t help but feel a strange sense of pride for having caught Sangwoo’s attention. He knew this was only to get his grade improved, but Sangwoo didn’t have to do this. Didn’t have to kiss him.
Sangwoo’s hand tightened onto Bum’s neck before he roughly broke the kiss. His cold stare met Bum’s drunk gaze. “You’ll give me a passing grade on that assignment.”
Bum gulped, his lips wet and breath short. He nodded.
Sangwoo pushed down and Bum’s legs instantly buckled. He dropped to the floor, cringing as his knees hit the hard linoleum. He looked up through his lashes at Sangwoo, his hands fisting in the tops of his pant legs as Sangwoo slowly undid the fly of his jeans.
The zipper creaked open as Sangwoo continued in a commanding monotone, “You’ll give me passing grades on all of your assignments.”
Bum’s breath shuddered out of him as Sangwoo unearthed his thick member. It was bigger than Bum had even imagined, long and well shaped, a slight curve to the underside. Bum’s mouth watered looking at it, the tip enticing him with a small sheen of precum smeared over the head.
Sangwoo’s hand slid through Bum’s hair, pushing a lock of it back and then tightening in it. Bum looked back up at him, his mouth dropping open.
Sangwoo sneered. “I knew you were a perv, but I didn’t expect you to be such a slut,” he murmured.
Bum’s face flushed, shame and humiliation curling in his stomach, but all of those emotions just added to the tightening bundle of pleasure in his groin.
He exhaled softly as Sangwoo pulled his mouth in closer, but held him back just barely a breath away. Bum’s eyes flashed back up at him, then widened when he saw Sangwoo was holding his phone in his free hand. Oh no.
“Now say it, Professor Yoon,” he rumbled, grinning again. “Say you’ll give me a passing grade for the rest of the semester.”
Bum cringed, looking away from the phone camera, but Sangwoo’s fist in his hair jerked him back. He looked up, the shame clear on his expression as he croaked, “I’ll give you a passing grade for the rest of the semester.”
“Good~” Sangwoo purred. “Now open that slutty mouth again.”
Bum pouted for a second, and then did as he was told. He was in this far. There was no going back at this point.
He was not prepared for Sangwoo to shove his dick in with the force of a battering ram. Bum instantly gagged, his eyes popping open wide as the huge thing stuffed into his mouth, hitting the entrance to his throat. “HRK!” Bum squeezed his eyes shut as Sangwoo pushed his hips forward, trying to force in more for a few seconds before he backed off.
“Damn,” he murmured as Bum panted around the head. “I was hoping to get it all in first go. Oh well.” He tipped Bum’s head back, slowly popping the head from his mouth to rest it on top of his lips. He still held the camera in his hand, recording everything.
Bum stared up at him, brows turning up as he slowly lapped at the head. He wasn’t sure he’d ever be able to get that whole thing down his throat.
Sangwoo let Bum’s head tip back down, keeping him still as he guided his cock back into Bum’s mouth and then began to thrust. Bum moaned softly, sucking as best he could, cringing each time the tip hit the back of his mouth.
“For being such a slut you really suck at this,” Sangwoo drawled, lazily thrusting his hips, not even getting half of his cock in. “No pun intended.”
Bum’s already red face flushed harder. He didn’t have any experience in this, only what he’d seen in porn. He slurped around Sangwoo as saliva started to pool in his mouth, his pale flesh now shiny with drool.
Sangwoo groaned, and Bum’s eyes flashed back up to him. There was definitely heat in his eyes now. Was it the sounds?
Bum grunted as Sangwoo’s pace picked up, the fist in his hair pulling his head back and forth in time with his thrusts. His eyes started to water as the head smashed against the back of his mouth over and over, managing to get another half an inch in.
Bum gasped when Sangwoo abruptly pulled out, moaning when he rested his slick, heavy cock over his face. Bum licked at the underside, his lips a little swollen, looking back up at the man.
“You’re going to take it all,” Sangwoo deadpanned. Bum’s stomach dropped. There was no way. That thing was practically as thick around as his own neck! Sangwoo arched a brow. “You’re going to take it all, or this video is getting uploaded.”
Fear nestled in Bum’s chest. He’d be fucked if this got out. Sangwoo wouldn’t do it, would he? Not when he’d already agreed on the terms, right? Looking up into Sangwoo’s hard face though, Bum wasn’t so sure.
Sangwoo licked his lips as he pulled Bum back onto the head. “Ready?” he rumbled.
Bum didn’t know how to prepare, but didn’t have the chance to think about it as Sangwoo started to push in. He went slower this time, the shaft sliding past Bum’s lips until the tip found the entrance to his throat again. Bum coughed as Sangwoo applied more pressure, his eyes squeezing shut. He didn’t know what else to do, it wouldn’t fit!
Sangwoo bared his teeth, pulling on Bum’s hair. “Come on, slut, do you want this to get out?”
Bum gave him a desperate look, dark eyes swimming from effort.
Sangwoo’s upper lip curled before he pulled out again. “Maybe you just need a little more encouragement,” he rumbled, letting go of Bum’s hair and ripping the back of his hand across his face.
Bum reeled back, stars erupting before his eyes. His face pulsed with the beat of his heart as blood rose to his cheek, the pain not registering yet. He’d never been hit that hard. And yet, he felt like that was only a sliver of Sangwoo’s strength.
He was still in shock when Sangwoo grabbed the top of his hair and slammed his head backwards, banging it against the edge of the table. Bum cringed, whimpering as pain spiked through his skull. Sangwoo held him there, impatiently shoving his cock back into Bum’s mouth and thrusting forward.
Bum’s eyes popped back open when he felt the head sink deeper, his throat spreading open to take in more. It was only about another inch, but even still, he couldn’t believe any more of it was in at all.
Sangwoo groaned, the phone still grasped in his hand. “Getting better,” he growled. He pulled his cock back again, and then slammed forward, putting all the weight behind his hips.
“ HRK !” Bum’s eyes rolled as he felt his throat give, and Sangwoo’s length finally slid inside with a wet squish. His neck puffed out as Sangwoo’s cock spread him open, pushing in until Bum’s nose pressed into the soft cotton of the man’s briefs.
“Aahhhh~ now see? I knew you could do it,” Sangwoo hummed. Bum’s throat twitched and spasmed, trying to adjust to the huge intrusion. “Come on, look at the camera, slut.”
Bum’s eyes fluttered up to look into the phone, and then up farther to look at Sangwoo. He looked massive from this angle, towering over him, and the grin on his face was of someone who always, always, got what they wanted. It hit Bum then that he would never win against Sangwoo. There was no use fighting him, no use trying to deny him. That calm certainty let Bum relax his entire body. His jaw opened wider, throat loosening. Keeping Sangwoo’s gaze, he slowly stuck out his tongue, rubbing it against the underside of his base.
“Now you’re getting it,” Sangwoo growled, as if he could read Bum’s mind. His next thrust was as rough as the first, pulling almost all the way out before he slammed his hips back. Bum’s throat gagged, drool spilling from his mouth and splattering onto the floor, but he didn’t move away. He just kept staring up at Sangwoo, flushed face submissive as his eyes streamed and his throat gurgled.
Sangwoo began thrusting in earnest, his clothed hips thumping against Bum’s face like he was thrusting into nothing more than a fleshlight. It hurt. Bum felt like his throat was on fire, every pass of that thick cock scraping over his torn skin. But he knew Sangwoo didn’t care, and knowing that had precum dripping from his own erection, staining his underwear.
Sangwoo took a deep breath, pausing for a moment to widen his stance. Bum took as many breaths through his nose as he could, wetness crackling through his sinuses. He looked up with cloudy eyes as Sangwoo readjusted his grip on Bum’s hair, and then mercilessly pushed back in. The big man groaned, biting his lip and quickly humping into Bum’s face. His speed was double what it was before, but he only moved a few inches at a time now, churning the thick saliva filling Bum’s mouth.
Bum couldn’t breathe. Couldn’t think. His head knocked against the table with every rough little thrust, and he felt strands of his hair pluck from his scalp from Sangwoo’s tight fist. Nothing had ever felt so right.
Sangwoo groaned, shoving his hips into Bum’s face and grinding hard against him before he jerked his sloppy cock back out. Bum coughed hard, sucking in a breath just before Sangwoo’s warm, sticky orgasm landed across his face. He flinched, closing his eyes and keeping his mouth open.
“What a good slut,” Sangwoo growled, stroking his dripping cock, coaxing a couple more thick spurts onto Bum’s face.
Sangwoo sighed, slowly moving the phone so he could get a nice, long look at every angle of Bum’s wrecked face. Bum’s eyes fluttered open, staring heatedly up at Sangwoo. He didn’t care about the camera anymore. He’d never been harder. He wanted more. More pain, more punishment. Anything.
Sangwoo grinned as he stopped the camera and put his phone away. He zipped his pants up, staring down impassively at the man. He eyed him up and down, then grabbed his paper and stuffed it back into his backpack. “Told you we could come to an arrangement.”
Bum just watched him, too strung out to even wipe his face. He continued to watch Sangwoo turn from him, the man waving casually. “See you tomorrow, Professor.”
