San groaned loudly and leaned back in his chair. He ran a hand through his hair, pushing the strands out of his face - only for them to fall right back as soon as he removed his hands.
His gaze flitted towards the clock on his wall, the pointer clock had barely moved from the last time he had checked the clock. With a sigh San leaned back over his desk and the papers he had to grade. Every final season it was the same and yet he never actively tried to change something. Not that he necessarily wanted to change a thing. A smile played over his lips, remembering why all this stress was worth it in the end.
When you opened the door to San’s office, you found him hunched over some papers, head resting on one hand while he read over the words with a frown on his beautiful face. It felt almost like a deja vu seeing him like this, though it’s been a while since you last saw him.
You silently closed the door behind you, keeping it unlocked despite knowing anyone could walk in on the both of you in a few minutes. Just the thought made you thrilled already.
“Professor”, you greeted him as you leaned your hip against the side of his desk, arms crossed over your chest and a challenging expression painted on your face.
San looked up, a fleeting smile crossing his lips. It was always the same. “Professor”, he answered with a smirk and leaned back in his chair again. San intertwined his fingers behind his head, waiting for you to do the first move as usual.
You clicked your tongue and rolled your eyes while you tried to hide your knowing grin. “You’re working awfully late again, professor.” You walked around his desk and pushed his chair away, turning him to face you as you leaned down to meet him eye to eye. “Did nobody tell you to take breaks before the stress builds up too high?”
“I wish it would be that easy, professor”, he purred while he placed one of his hands on yours. “Not everyone can use multiple choice tests that can be corrected by a machine.” He didn’t mean any malice with his words, he never did, it was simply part of the game between you two.
“You could use it”, you murmured, leaning close to his lips, “if you actually wanted to.” Both your breaths mixed with each other, the soft skin of your lips barely brushing against one another while you spoke.
San inhaled shakily before his hands grabbed you by your waist and neck, pulling you against him so he could kiss you deeply.
Just like all the times before you wrapped your arms around his neck and straddled his lap to get even closer to him. The attraction between the both of you had been an open secret for years now and even new students quickly started to ship the both of you - not even to mention some of your colleagues.
Yet nobody ever saw you two alone together. It made your little game every time around finals season even more exciting.
“You still need to take a break, professor Choi”, you gasped against his lips, unable to pull away just yet.
“Having you here is more than enough of a stress relief”, San purred and his hands wandered over your sides, toying with the hem of your top. “It saddens me that I need to finish grading these though.”
“I could help you while you do it”, you offered. You looked through batted eyelashes at him, your hands slowly running over his chest and hips rolling against him.
“You’re such a minx, Y/N”, San groaned and grabbed your hips, keeping you still. It was the same every damn time and yet he could never get enough of this. “Will you be good for me?”
You nodded - almost too eagerly - and pecked his lips before you stood up and waited in front of him.
“On your knees.”
You dropped without an ounce of hesitation down to the floor, kneeling in front of San and looking up at him with expectant eyes. Even though you knew what awaited you, you loved playing innocent, making San groan in pleasure just from your expression.
“Did you lock the door?” He asked and motioned for you to move under his desk. A smirk spread over his lips when you shook your head. “Naughty, aren’t we? Does it turn you on, knowing we could get caught?”
You pursed your lips, having enough of his teasing. You placed your hands on his thighs, slowly stroking over the fabric of his pants while getting closer and closer to his crotch. “Just as much as you like the thought, professor Choi.”
He only chuckled and shook his head, leaning back in his chair as he opened his pants. His dick immediately stood proud, the tip already glistening with pre cum. San rolled closer to you with his chair, relaxing into the cushions while he watched you through half lidded eyes.
You spit into your hand before you wrapped your fingers around his shaft, leisurely pumping him. Whenever you reached the top you gave your wrist a slight twist, admiring the soft moans San made because of that. You licked over your lips and wrapped them around the head of his cock, tongue swirling over the slit.
San threw his head back with a groan, one hand grabbing some of your hair.
“So sensitive”, you giggled and blew over his tip, making San shudder underneath you. “You’d never be able to do anything else while I give you head.”
San scoffed and tried suppressing the next moan. “I could easily grade these papers while you suck me off.”
“Oh yeah?” You increased the pressure of your hand, seeing San nearly falling apart in front of you.
He bit on his lower lip and glared at you. “Definitely”, he growled and pushed you further underneath the desk, pulling some of the papers closer to him as he tried reading the contents.
You only giggled and continued to kiss and lick his cock, moving your hand with the same rhythm. It was almost adorable how he always wanted to prove himself, despite failing every single time. Last time San barely read through half a page and couldn’t retell anything from those few lines.
You licked along the underside of his shaft, loving how thick and heavy he felt on your tongue. You kissed his head one last time before you wrapped your lips around his dick, cheeks hollowing while you slowly pushed your mouth down on him.
You hummed, pleased to hear San’s irregular breathing above you. Even though you couldn’t see him due to the desk between you, your fantasy didn’t betray you, picturing him perfectly: hunched over the desk, head in his hands, hair standing wild and eyes either wide and unfocussed or screwed shut while his lips were parted in pleasure.
You slowly bopped your head, never taking him too deep as you continued to tease him. Enough for San to move one of his hands back down under the desk and into your hair, twirling a few strands around his fingers.
His grip tightened when a knock sounded from the door, pulling you down on his shaft unwillingly. San cursed lowly, feeling his heart inside his throat.
You quickly tried to breathe through your nose, ignoring the urge to gag as the tip of San’s dick was pushed against the back of your throat. With your blood rushing through your ears it became incredibly hard to hear the door open.
“Professor Choi? Could I talk to you about my final project?”
You recognised the voice as one of your top students, Choi Jongho. Your eyes flicked all over the place while you tried to think of something.
San still hadn’t said a word, only keeping you pushed down on his dick with your nose pressed against his pubic bone. He exhaled loudly, his grip tightening even more, when you moved your tongue and swallowed around him.
“I’m in the middle of grading papers, Jongho”, San spoke up, his voice way too strained.
“I’m sorry professor but it’s really important.” Jongho moved closer to the desk, sparking a flame of fear inside of San as he quickly leaned forward and hoped to hide everything from you.
“Make it quick then”, San grumbled.
While Jongho sat down in front of San and started explaining his problem, you grabbed San’s hand and moved it out of your hair, slowly moving back and relaxing your jaw again.
You intertwined your fingers with his, squeezing them reassuringly. All while you continued to pump his cock. He was painfully hard in your hand and you knew San would soon come undone if you kept it up.
San squeezed your hand as if he tried to warn you, yet you ignored it and wrapped your lips around him again, hollowing your cheeks and sucking him off without making a sound.
You heard San thrum his fingers on the desk, getting more and more impatient the longer Jongho stayed in his office. “I don’t think I can give you a well rounded answer to your problem right now”, San pressed, screwing his eyes shut as everything within him fought against cumming. “Can I ask you to send me an email regarding this? I need some time to think about it, Jongho.”
“Are you alright, sir?”
San wriggled his hand out of yours and held you still again, looking up at Jongho with a stern expression. “Just a headache”, he murmured and rubbed over his forehead with his free hand.
“Oh”, Jongho said, nodding in understanding, “then I’ll leave you to it.”
You heard the chair scratch over the floor, followed by Jongho’s retreating steps and the door closing at last.
San groaned loudly and leaned back in his chair. He ran a hand through his hair, pushing the strands out of his face - only for them to fall right back as soon as he removed his hands.
His gaze flitted towards the clock on his wall, the pointer clock had barely moved from the last time he had checked the clock. Even though it felt like an eternity to him.
“You did that on purpose”, he growled, his eyes darkening as they dropped down to you. “Wanted to get caught so bad, didn’t you?”
You simply hummed around his cock, a teasing glint shimmering in your eyes as you stared back up at him.
“Did you like it? Choking on my dick? You’re wishing for it to happen again, don’t you?” San ran his fingers through your hair until his hand was placed at the back of your head. “Tap twice if it gets too much”, he instructed right before he pushed you down again, hitting the back of your throat once more.
Tears welled up in your eyes while San continued to fuck into your mouth, chasing the high he had to push back for so long. His release came out in thick ropes, letting you nearly choke again from the force behind them.
San wiped over your tear stained cheeks with a coo. Dimples appearing on his own cheeks from the smile that formed on his lips when your eyes met. “You were so good for me”, he praised you and pulled out of your mouth, watching you swallow his cum while he tugged himself away.
He never was this rough with you before, though they never got interrupted before either. San tilted his head, looking at you and helping you up to your feet again. Did you finally get out of the repetition the both of you faced every finals season? Was the interruption from Jongho a sign he should break out of this repetition? It wasn’t that San didn’t feel attracted to you but would you be up for it? Be up for more than simply pleasing each other whenever it was a little stressful around college?
“What are you thinking?” You asked, one hand over your throat once you heard your horse voice. You chuckled softly and leaned back against his desk, looking down at San and waiting for him to answer your question.
San ignored your question and stood up himself, towering over you as one of his hands came up to your throat as well, concern shimmering in his eyes. “Are you alright? I didn’t hurt you, did I?” He cupped your face, thumb stroking over your cheek and eyes searching for an answer.
You placed your hand on his, nuzzling your face into his large palm. “I’m fine, San.” You laughed softly and met his eyes. “I liked it. It was something new for once.”
San bit down on his lower lip, contemplating his next words. “Do you want to experience more new things with me?”
Before you could answer, Jongho barged through the door again. “Professor! I just remem-” He stopped mid sentence, his eyes switching between you and San.
Instead of pulling away from each other both of you simply looked at Jongho, waiting for him to continue whatever he had to say.
“Professor?”
The corners of your lips turned up and you looked back at San. “I’d love to”, you whispered and placed a kiss on his wrist. “Finish up your work and come to my place. Dinner will be ready.” You pushed yourself from his desk and walked towards his office door, smiling gently at Jongho. “Your project sounds interesting.”
Jongho blinked rapidly, struggling to wrap his mind around the situation.
“Jongho, take a seat!” San ordered him as he rounded his table as well, running after you. He grabbed your wrist and pulled you against his chest. “I’ll wrap up as soon as possible”, he promised you while he stole one more kiss from your lips, turning back to a flabbergasted Jongho with a bright grin ready to solve his problem as fast as possible so he could meet up with you again.
