Chapter Text
Your paper was dropped down onto your desk, a waft of cedarwood and tobacco hitting your nostrils as your professor swept past you. Glancing down, you blinked at the sight of a dark red ‘F’ scrawled at the top of the page. Underneath was written see me after class – no objections. You sighed, slumping back in your chair.
Finance was not your forte. Being a university student, you were an intelligent girl and countless people had told you so. You eagerly marched into a business degree with little thought for anything other than making money. Business and marketing – there was money in that field, right? You did well. You passed your first two years with flying colours, professors singing your praises all the way. And then you hit your third year. Twenty-one and a new-found wave of exhaustion settling into your bones, you were on the verge of admitting defeat. You had almost given up the course entirely, until your mother informed you that she had been let go from her job. It hit you then – the pressure. The need for a good job, and therefore, the need for a degree.
But this module in finance was practically crushing you. Maths was not your strong point, and your professor was not what you could call… approachable.
Mister Cho had an air about him that intimidated you, to put it simply. He was an older, very intelligent man who commanded immediate authority over his students. Nobody dared talk back, he was well-respected amongst staff and students. His most admirable feat: he had an almost one hundred percent pass rate. Well, he did. Until you came along.
You were trying. You kept telling yourself you were, but you found yourself distracted during each lecture, staring at your handsome professor as he stood in front of hundreds of students, teaching with unwavering confidence. He explained concepts thoroughly, attentive to anybody who needed some extra help. The way his eyes lit up when a student answered a question correctly made him even more handsome. You were distracted. Distracted to the point that you had failed two out of three of the last quizzes that your professor had set.
Enough was enough, apparently.
As the students filed out of the lecture hall, you did not move from your seat. You slowly packed away your things, watching as Mister Cho took a seat as his desk. He watched as you slid your bag onto your shoulder and picked up your graded test, and he watched as you walked over to his desk. He sat up straight, one leg folded with his ankle resting on his knee. You could see that his socks matched the deep navy of his tie. You finally made eye contact.
“You wanted to see me, sir?”
“Sit.”
You obeyed immediately.
A slight smirk curled at his lips, and you swallowed, sinking down onto your chair. You mentally prepared yourself for a lecture, but you felt yourself already getting distracted just by looking at him. God, he was handsome. His large hands sat on the desk; long fingers linked together. Your mind started wandering. What would those fingers feel like as they dug into your hips, tugged at your hair, slid between your thighs to press against your suddenly aching centre-
“I’ll be straight with you, (y/n),” Mister Cho says suddenly, startling you out of your inappropriate daydream. “Your grades this semester have simply not been good enough. It’s a surprise, I’ll admit. I had heard you were such a smart girl… why are you letting me down like this?”
His tone sounded almost hurt, and it had you leaning forward on your chair with a frown. “I’m sorry, professor.” You didn’t want to let him down. God, no, you wanted him to be proud of you. You wanted to please.
“I didn’t ask for an apology. I asked for an answer. Why are your grades slipping? Is it my teaching?” He scoffed. “Because I know that that cannot be the case. Every other student passed. So, tell me,” he leaned forward, arching a brow. “What’s got you so distracted?”
Your cheeks burned as you sat back in your chair. You shrugged your shoulders, unable to think of an appropriate response.
“Do not shrug at me, you insolent child. Or do I have to teach you basic manners as well as this course?”
“I’m not a child-” you protest quickly.
“Then answer the question.”
“I just- I don’t think I grasped the basics, sir. It’s made everything else quite difficult; you see.”
Mister Cho studied you for a moment before scoffing, leaning back in his chair. “Bullshit.”
“I’m sorry, sir?”
“Do you think I’m a fool, (y/n)?”
“No, sir-”
“Do you think I’m incapable of telling when one of my students has become so overcome by their thoughts that they can no longer focus on their work?”
“I-”
“Tell me, sweetheart. How many times in the last week have you thought about choking on my cock? About kneeling underneath my desk while I teach thousands of students, my cock deep in your throat. You’ve thought about it, haven’t you? You’ve thought about my fingers in your cunt, hmm? Or did your little whore brain surpass that? Did you dream about me splitting you open instead?”
To say he caught you off-guard would have been an understatement. You gawped at the man, words jamming in your throat. You managed a squeak of surprise, head nodding of its own accord.
“You did,” he purred, a smirk sliding onto his face. “Dirty girl. Here’s what I’m going to propose. Are you listening?”
You managed a nod. You didn’t trust your voice. He raised an eyebrow, clearly unimpressed and you cleared your throat. Forced out a “I’m listening, sir.”
“Good girl. I think the only amicable option is to get rid of all your distractions. Clearly, you’re a daydreamer. After all, you’re so busy dreaming about me that your classwork is failing. I will give you exactly what you want. And in return, I expect full concentration from you in class. I expect top marks. Do you think you can do that for me?”
There was no way that this was truly happening. You pinched the skin of your arm, wincing when you were met with a jolt of pain. This was happening, and that equally terrified and delighted you. Sang-woo noted your apprehension.
“There is no pressure, my dear,” he added, arching a brow. “If you refuse, I’ll assign you extra study classes. I’ll give you some easier work to attempt before we continue with the actual coursework. Maybe that way, you’ll catch up.”
You’re shaking your head before he manages to say another word. “No! No, I want to!” Then after a moment, you murmur a “Please don’t assign me more work.”
Sang-woo grins. He leans forward, long fingers gripping your chin as he forces you to look at him. “Oh, sweetheart,” he coos, pouting teasingly. “I think more work would just make your pretty little head explode, wouldn’t it? Not to worry. Pretty whores like you don’t need to think, so you’re in luck,” he presses his thumb to your bottom lip and upon instinct your mouth falls open. Your professor pushes his thumb into your mouth, and you immediately suck, eyes never leaving his as your tongue slides around the digit.
“All I need from you… is a hot, wet mouth,” he grits out, biting his lip as he watches your plump lips close around his finger.
Pulling away, he beckons you closer with a crooked finger. He scoots his chair back, fingers moving to the zip on his slacks. You stand up on trembling legs, still clutching onto your test paper as you move to stand beside him. He looks at you, chuckling as he pulls the paper from your hand and sits it on your desk. You can smell cigarette smoke from this close, along with the intoxicating scent of his aftershave. “Kneel for me, there’s a good girl.”
You move in front of his chair, bare knees hitting the wooden floor a moment later. You gaze up at him as you lean forward, pressing soft kisses over the slight bulge in his trousers. He exhales, reaching into his pants to pull out his half-hard member. “Have you ever sucked cock before, (y/n)?” he drawls, lazily sliding his hand up and down his length. You watch, taking your lower lip between your teeth as you nod.
“A few times, sir.”
“Good,” he flashes you a wicked grin. “I don’t want to be gentle. Open up,” he murmurs, pressing the head of his cock to your lips.
You don’t need to be told twice.
Opening your mouth, you eagerly take the head of his cock inside and wrap your lips around the hot, throbbing tip. A soft moan escapes you and your eyes shut, cheeks heating up as you slide your tongue around him. Sang-woo curses above you, his fingers tangling into your hair. He watches with dark eyes as you open up your throat to take in as much of his length as you can, teeth sinking into his lower lip to stifle a groan.
Your eyes flutter open and you gaze up at him, eyes locking with his as you bury your nose into the dark hair resting at the base of his cock. His grip tightens and he holds you in that position, hips thrusting up to fuck himself deeper into your throat. Your professor groans, his head falling back as you swallow around him, tightening to hot, wet shaft surrounding his cock. You allow him to use your throat and he uses your hair to move your head for his pleasure. Moaning around him, you can’t help but slip your hand between your legs, thanking past-you for choosing a skirt to wear that morning. Within a second, he’s tugging your head up and gripping your jaw with a firm hand. You gasp in surprise, lips obscenely red and mouth achingly empty. A line of drool connects your lower lip with the head of his cock, and you pout. “No-”
“Did I say you could touch yourself?” he all but growls, pressing his fingers into your jaw a little harder. “Hmm?”
“No, sir, you didn’t, but I-”
“You couldn’t help yourself, could you? Your slutty little pussy couldn’t be ignored for a few more moments, huh? Pathetic,” he sneered, and you could practically feel your wetness dripping through your panties at this point. You rather liked it when he was mean to you. Hopefully that was just a weird sex thing as opposed to an actual psychological defect. For a moment, you were rather concerned that he could read your mind, as he bent his neck forward to move closer and spat right into your open mouth. You whimpered in surprise, swallowing without another thought as you gazed up at him. His eyes were practically black.
“’m sorry, sir,” you mumble, shifting on your knees. “Lemme suck your cock again, please, I’ll make it up to you.”
“I know you will, pet,” he murmured, brushing a gentle hand through your hair once more. “Now, lift your hips.”
You did as he asked, raising your hips up slightly and watching with wide eyes as his foot slid between your thighs. Right below your cunt, to be exact.
Immediately, you knew what he wanted from you. You lowered your hips down again, settling your closed pussy on his (assumedly) rather expensive brogue. A little grin appeared on your lips, and he raised an eyebrow in questioning. “You’re a pervert,” you giggled, shifting yourself just enough that you were able to get a taste of that delicious friction.
“If we’re stating the obvious,” he drawled, leaning back in his chair, and gripping the base of his cock, “you are a disobedient slut. Now, I want you to make me come. You are to hump my leg, like the pet that you are, but don’t you dare think about coming until I have. Am I clear?”
You nodded, licking your lips. “Crystal, sir.”
Wasting no time, you took Sang-woo’s cock back into your mouth. Lapping at the pre-come that had gathered at the head, you tried not to look too pleased with yourself as his eyes rolled back when you hollowed your cheeks and sucked on him. You ground your hips down against his shin, soft whimpers falling onto his cock as your hands worked what you failed to fit down your throat. “You’re so big, professor,” you moaned, mouth sliding back over his length, and you refused to stop until he was fully situated down your throat. The head hit the back of your throat, and you could hear him release a string of curses as his fingers once again tangled into your hair.
“Fuck, just like that. Don’t you dare stop.”
You wouldn’t dream of it. All while grinding against him, you bobbed your head up and down, cheeks hollowed and hands gripping onto his hips to steady yourself. You could tell he had to be getting close. He was far laxer with the noises he let slip and thank God as you were not too far behind. The front of his shoe sat perfectly against your button and each time you rocked your hips, it pressed against it deliciously. You were trembling, slick and obscene noises filling the lecture hall as you gagged and whimpered on his cock. You gazed up at him with big, pleading eyes. He chuckled, hand sliding from your hair to cup your cheek as you paid attention to his tip.
“Pretty girl,” he moaned, thrusting his hips up into your mouth. “Such a desperate little pet, aren’t you?” he purred. “You need it bad. I knew… since the moment I set eyes on you… that this was what you needed. This is what you were born for, wasn’t it? You need all those difficult exams to disappear. All you need is a cock in your greedy little mouth and something between your legs, and you’re satisfied. Isn’t that right?”
His words were coming out slower now, moans escaping between every few words. He gripped onto your hair tight, drawing your head down one final time before he groaned, spilling into your mouth. You whimpered, your own hips stilling as you finally came, soaking your panties thoroughly as you gripped onto his hips.
A few moments later, Sang-woo pulled his cock from your lips, slipping it back into his trousers and zipped them up. You swallowed, wiping your mouth on the back of your hand as you attempted to stand up. Your legs were not as prepared as you’d have liked them to be, however, as you stumbled, a surprise cry leaving you as they threatened to give way. He caught you, standing up with a soft, almost fond, smile as he slid his arms around your waist.
“There, there,” he murmured, reaching for a tissue on his desk to properly wipe your mouth. “You did well, pet,” he said, tipping your chin up gently with his pointer finger. You blushed, feeling oddly shy now that your initial arousal had worn off.
“I can’t believe that just happened,” you whispered, staring up at him.
“Do you regret it?”
“No!” you protested a little too quickly. He smirked. “No. I didn’t say that.”
Sang-woo’s hands rested at the small of your back, and he pulled you in closer, ever-intense eyes still gazing into yours. You closed the gap, pressing your lips to his in a tentative, sweet kiss that almost felt wrong after what the two of you just did. The man had spat in your mouth, for God’s sake, although as you felt his tongue slide into your mouth, you decided that perhaps it wasn’t that different after all. Your arms looped around his neck as the kiss deepened, moaning softly.
He pulled back a few moments later. “You should head home,” he said softly, brushing a finger over your cheek. “Class ended a while ago. I’m sure your friends will be worried.”
“Mhm,” you nodded in agreement. “So worried. How on earth do I tell them I just sucked my hot professor’s dick?” you were teasing, but his hold on you tightened.
“You don’t. I mean it, (y/n). I could lose my job over this-”
“I’m teasing! I know!”
He seemed to relax at that. “Good girl. You know, (y/n), you’re not stupid. I don’t think that of you. I just get… carried away. You’re very capable. I do believe you’re distracted, however, so if you could fix that, I’d be pleased.”
You chuckled, pressing a kiss to his cheek before you pull out of his grip, picking up your bag.
“No promises, professor. I think I might need you to teach me a lesson again.”
