You didn’t have the best life in the world, matter of fact, things seemed to get increasingly hard as you grew up.
As a kid, you had to fend for yourself. Your parents were those kind of parents, the ones that didn’t care much for their children. As far as you can remember, your mom would be out in fancy dates with your dad and they’d leave soup in the microwave for you.
Of course, with those things piling up from your childhood, you never came to have a great relationship with your parents. And even if it sometimes hurt, you brushed it off as something that made you grow as a person.
Because of that, you grew to be responsible and really studious. Wanting to follow a path that your parents didn’t follow- you wanted to do things in the name of the law. And you were pretty set on that.
Until that godforsaken day happened, you were just coming back from your parttime job when your mom dropped the bomb that she was pregnant. She, of course, was overjoyed. So was your father, but you knew what that meant.
They would just be happy for now, and once the baby was born, they’d probably dump the responsibilities into you. Even if deep down you hoped they wouldn’t do that, you knew they would.
You grew to be worried, how would you be able to handle taking care of a sibling and go to university? You had already enrolled into a big university.. Seoul university. It was a prestigious one, but still, you had tuition to pay.
But as the months went by, you felt those worries melting away for a little. You didn’t see your parents often, you made new friends throughout your studies, life was going pretty well.
But then, your baby brother was born.
And what you most feared had happened, a few months in and you were responsible for your brother while your mom went to parties. Tsk, it wasn’t any different from what she did to you.
You were worked up to the neck, but you never showed it to your brother who clearly looked up to you. You were like his hero, someone he could rely on for anything. So you never let it show.
That was three years ago, and life hadn’t gotten any easier. Your brother was now three, and most of the times you dropped him off at preschool before going to university.
You were sprawled over in the bed as warm rays of sunshine peeked through your light cover curtains, the warm breeze of spring slowly slipping inside your bedroom through your barely open window. You were tired, managing all kinds of things at once was immensely difficult, plus the fact you worked extra late for some more money last night. And there was the fact you also had a huge amount of piled up work.
Paperwork was scattered across the floor, ones which you tried to complete last night but failed miserably before you passed out in bed. You tried to keep yourself up mostly because of your professor— he sort of freaked you out.
Roh Nam-gyu had to be one of the scariest professors around the place, you weren’t sure if he was trying to be intimidating because this was his first year working in the university, but something about him made you feel small.
You convinced yourself the way he seemed to be closely watching you was your paranoia eating you alive or how you lacked sleep, opting for averting your gaze from his eyes that resembled a cat’s, sharp and dark. After all, it would be weird for him to be watching you, right?
You were pretty sure he had a wife and a daughter, either that or he was divorced. How could you possibly know that? Well, rumors spread quickly in that huge place.
Back to the present moment, however. Your very much peaceful slumber was disturbed by the feeling of someone jumping on top of you and shaking you awake. Sometimes you forgot you had an energetic three year old to care for.
"Sissy!" He’d call out, making you groan out loud as you opened your eyes, immediately shutting them back as you were met with the rays of sunshine. You’d fall back asleep, but the little boy seemed determined to wake you up.
Blinking slowly to get your eyes used to the sunlight, you sat up in bed to find your brother already ready for preschool. The fact that he knew how to get himself ready made you feel proud— it meant he took after you, in some ways.
"Buddy.. it’s Saturday, why are you dressed up for school?" Your voice was raspy with sleep as you checked your phone. Your eyes focused first on the date— Friday, and then at the timing. And fuck, you were going to be late.
A giggle left your brother’s lips as you jumped off of bed, rushing towards the bathroom while you bit back all kinds of curse words towards the universe as you tried to figure out what would be quicker and what you’d have to exclude from your daily routine to not be late.
You brushed your teeth, did your personal hygiene as quickly as you could, and proceeded to move onto your hair that was not only messy but tangled— fucking tangled.
The universe seemed to be conspiring against you, for some reason.
In the end, you ended up with a half-assed bun that was definitely quite weird looking (but you couldn’t really bring yourself to care), and barely any makeup except for mascara and your favorite lipstick.
Clothing wasn’t much of an issue either, you were smart enough to pre plan your outfits every night before sleeping. It was simple, some jeans, a white blouse and black loafers that were practically begging to be thrown away already due to how much you used them.
You gave your brother some cereal while you ate an apple and a few grapes before getting in the car, quickly driving your brother to preschool while praying nobody notice how you were going past the speed limit by the second.
Waving off your brother goodbye and giving him a kiss on the cheek, you apologized to his teacher because of the clearly late timing before hurrying off to drive towards university already.
Your feet were moving as fast as they could the second you managed to get out of your car after finding a parking spot, ignoring the lack of air you felt due to having a basically shit kind of stamina, you reached the front door.
Embarrassedly, you got a late pass from the main office, apologizing for any inconvenience to the receptionist before you began making your way towards your classroom.
You felt the weight of the world into your shoulders, already imagining all kinds of possible scenarios the second you knocked on the door. Just thinking about the piercing and uncomfortable stare your professor would give you made you get goosebumps.
After hesitating for a bit and questioning your whole existence, your knuckles finally met the door in a knocking motion, head ducked down as you waited for him to open the door.
You bit your lip to try to alleviate some of your nervousness, grasping onto the late pass like some sort of lifeline. And then, finally, the door opened. And you met his eyes, those damn eyes.
Nam-gyu’s eyebrows were furrowed as he looked at you up and down, the same expression he’d have whenever he was pissed. You basically shoved the pass into his hands before spluttering out an apology and bowing. You heard a sigh leave his lips, and you felt ashamed.. knowing how being late was looked at negatively in Korea.
"Go to your seat, Miss L/n. And I hope this doesn’t happen again." He said rather sternly, and you thanked him before hurrying off towards your seat next to one of your friends.
No words were shared in particular, but judging by the stare she gave you, she was quite literally asking if you were out of your mind. Being late was already looked down upon, but being late to Nam-gyu’s class was almost if you had a death wish. Considering how he stares you down without saying a word, just deeply judging you. And maybe even your soul, as if he could see right into it.
Not wanting to catch his attention too much, you finally began paying attention to his lesson. Your head kind of aching as he blabbered on and on about law, it’s not that you didn’t like the major.. otherwise you would just swap it out. It’s just that things have been so much as of late that everything made your head hurt. Especially when you were running on four hours of sleep.
At some point, you completely zoned out. You had worries, if you should quit your job.. what to cook for dinner tonight, if you should confront your parents, when would you arrange time to finally get done with your piled up assignments from Nam-gyu’s class, and so forth and so on.
Your palm was leaning against your cheek as you stared off into the nowhere, not even noticing your friend giving you a desperate warning stare to snap back into it, which of course, you didn’t catch onto.
A pen tapping onto your desk however, made you snap back to it. And there he was, Nam-gyu. Looking as intimidating as ever.
"Are you paying attention?" He asked with a raised brow, and you quickly nodded despite knowing damn well that you hadn’t been paying attention for the past fifteen minutes. "Then what does law no. 3.03 say, Miss L/n?"
You were silent, feeling your throat go dry before finally saying; "Sorry, I don’t know." And the sound of him annoyedly kissing his teeth made your heart nearly thump out of your chest. Your gaze was set downcast, looking anywhere but towards his eyes.
"Picking law as a major takes time and a lot of your brains, if becoming a lawyer is anywhere in your plans, then you have to pay attention. If you can’t handle that reality, pick another profession." Those words felt like a smack to your face, and maybe that was the intention. But then again, you never truly knew what Nam-gyu’s intentions were.
"Pay attention to class, next time I ask you something, you answer to me. These kinds of stunts can get your clients in jail, if I catch you zoning out again, I’ll have no choice but to ask you to share whatever is it that you’re thinking with the class. And afterwards, give you a detention. Am I clear?"
"Yes, professor." You said, not knowing where to hide your face. If you could dig a hole in the floor and hide in there forever, you would. But for now, you were just forced to handle the moment. "Meet me at my desk after classes." He finally concluded.. for some reason, quieter than usual.
Of course you picked up on how he basically mumbled, only for you to hear. Normally, he publicly announced things to the classroom, but this was almost as if it was supposed to be a secret. But you just brushed it off as another one of your delusions.
Thankfully, you never had to worry about picking your brother up from preschool. Your dad would do that favor for you. The only useful thing he does as a father, quite frankly.
"Girl.. good luck." Your friend murmured to you and you nodded, giving her an awkward smile before turning to finally fully pay attention to the lecture.
As boring as it was, the day finally passed. A relieved sigh leaving your lips, halfway cut through as you remembered Nam-gyu’s request to meet him over at his desk once everyone else left.
"Me and the other girls are going to this one restaurant around here, y’know? The one that we have been crazy about on the groupchat?" Eun-ja began, looking towards you with hope in her eyes that you’d finally hang out with them.. considering it’s been probably three months since you last hung out. "You’re coming, right?"
Biting your lip, you were deep in thought. You didn’t know what Nam-gyu wanted, so you couldn’t give her a yes for sure. Maybe you could arrive a little late? "I’m not sure if I’ll make it in time, sorry, Eun-ja." You sighed, frowning as you began slowly packing up.. slower than usual. "I’ll let you know if I can make it through text, but even if I do, I’ll probably arrive really late."
Eun-ja pouted, giving you that look that she always gave you whenever she was about to complain. "But it’s been like— forever since you last hung out with us! We miss you!" She whined, crossing her arms.
A chuckle left your lips as you shook your head in amusement, smiling at her. "I’ll try to make it, but if I can’t, I swear I’ll hang out with you guys next time." That alone was enough to brighten her face up, and then she extended her pinky finger towards you. "Promise?"
Intertwining your pinky finger with hers, you nodded with a smile. "Promise, now go, the girls must be waiting for you." And you watched a little hesitant as Eun-ja left the classroom, leaving you alone with Nam-gyu.
Your throat felt dry as you stared at him, who was sitting down at his desk with a book open. Slinging your bag over one of your shoulders, you tried your best to look calm as you walked towards him.
"Did you want to see me, Professor?" Your voice sounded strained, it was very obvious how nervous you were. Your hands fidgeted slightly, keeping them away from his gaze just so he wouldn’t question it.
His gaze slowly moved from the words etched in the book to your face, and you felt small under his gaze once again. His chin rested above his clasped hands, eyes feeling as if they were piercing into your soul, he seemed to enjoy torturing his students with silence.
"Are you aware you’re failing my class, Miss L/n?" He finally asked, of course he wanted to talk about your lowering grades. Even if it was embarrassing, you nodded meekly. "The marking period is nearly over and you’re nowhere close to passing, do you know how grave that is?"
"Yes, professor. I’m sorry." You said with a small pause, debating on your choices. "I’ll hand in my assignments as quickly as I can.”
A snort came from Nam-gyu’s lips as he tilted his head, biting his bottom lip as he stared at you with amusement. "Do you really think handing in past due assignments is enough to bring your grades up to a passing one?"
You haven’t been checking your grades.. but surely enough, there is no way your grades were that low, right? "You’ll get a 50% max for each assignment, Miss L/n. All depends on how past due the specific assignment is, even if you hand in everything, it won’t be enough."
"Then what can I do to pass this marking period?" You asked straight away, willing to go to big measures just to pass. You were paying to study, you had a future to build, after all. "I’m willing to do anything— I just need to pass this class."
The classroom was filled with a tense silence as you stared in his eyes, not knowing what possessed you to make you brave enough to hold eye contact. And then he tilted his head, a smirk sprouting in his lips. "Anything?"
"Anything." You said so sure of yourself, the famous last words, as they’d say.
Your mind felt hazy, ears ringing and thighs shaking. It’s not that you were a virgin— but from the experience you have, Nam-gyu is way more bigger than any other guy you ever slept with.
Papers were scattered all over the floor just like most of your clothes, except for your panties that were hastily pulled to the side. You just knew they were ruined, probably soaked. Feeling dirty was part of the package, considering Nam-gyu had a wife and a daughter. But hey, anything is anything.
Your voice was raspy, head lolling back in a stupid way that had Nam-gyu letting out a breathless chuckle. He was torturing you, most definitely. Hands gripping either sides of your hips as he gave shallow thrusts just to slowly inch himself inside of your cunt, so slowly you could feel every little bump and vein as he eventually eased himself inside of you.
"I’m barely halfway in and you’re acting like you’re being fucked into next week," Nam-gyu stated in a mocking way, you weren’t sure how he could manage to sound so calm while sinking himself into you. "What would your classmates think? You’re normally top of the class.." he trailed off, a heavy breath leaving his lips.
His words were mustered up to shame you— it’s as if he never stopped trying to do so. But you couldn’t really afford to get mad when he was slowly getting into your guts. "What would they think if they knew you’re taking my dick just to get your grades up?"
A breathy whine left your lips as he finally bottomed out, eliciting a groan from him. He stayed still like that for a bit, looking at you in the eyes. You could definitely tell he was enjoying himself. "You know that people are still around, right?" He asked with a furrow of his brow and a head tilt, slowly pulling out a considerable amount before slamming back in.
"Son of a b-" the sentence barely even fell from your lips before a moan was torn from your throat, and by this point, you knew he was doing this just to get you scared, maybe anxious at minimum.
"The door is unlocked, you know that, right?" He muttered as he leaned in, breath fanning over your cheek as one of his hands moved from your hip to the inner part of your thigh, squeezing it. The cold metal of his ring bit into your skin, bringing you back to a brief reality.
You were letting your professor fuck you.
Well, no shit. But not any professor, it was Nam-gyu. A married man.
You had seen his wife around before, she would bring him lunch at the beginning of the year before you never really saw her around before. Back then, you wondered what had happened to her but.. now you realized that maybe their marriage wasn't going well.
It didn't make you feel any less of a bad person.
And then, Nam-gyu set a steady pace. It wasn't fast or hard, but he made sure to go deep with every thrust of his hips. It brought you back to reality, a moan leaving your lips. He was in deep, you swore you could feel him all the way up to your guts.
"Look at that," He stated breathlessly, seeing the way your stomach bulged every time he thrusted back in. You clenched around him at the sight, it was weirdly arousing. "Your body is adjusting to take me in already.. fuck."
Your gaze was already half-lidded, brain short-circuiting every time his happy trail brushed against your clit. For safety reasons, you initially had a hand clasped over your mouth to muffle yourself. But then, Nam-gyu had moved it away, holding your wrist away from your face. "I want to hear you."
His voice was low, rough, even. His tip brushing against that spongy spot inside of you that had your eyes rolling back as a particular loud moan tore from your throat. And if you had thought he'd stop because of that, you were oh so wrong.
He picked up the pace, the hand on your thigh tossing your leg over his shoulder, allowing him to push impossibly deeper. Your head lolled to the side stupidly, your brain slowly fogging up and all you could feel was pleasure.
Warm and insistent, even overwhelming pleasure coursed through your body, every thrust hitting your sweet spot just right in a way your toes curled and your back arched off the messy desk. "You're so tight- fuck," Nam-gyu grunted above you breathlessly, that stupid smirk of his returning to his face as he saw the state you were in.
"Stupid slut, letting your professor have his way with you," He started off, giving your face a slight slap. It wasn't enough to hurt, but enough to bring you back to reality even if for just a bit. "Lying here all fucked dumb and cock drunk just to get your grades up, you're such a whore."
Tears pricked the corner of your eyes, but as much as you wanted to retort, you knew he wasn't lying. You wanted to speak, but your words got stuck in your throat. All you could feel was Nam-gyu, his hands, holding you firmly, his voice that seemed to scratch your brain, and his dick. Plunging in and out of you in a pace you couldn't catch up- being forced to just take it.
"If I knew you were such a slut, I would have done this before." He mumbled, watching you shake your head as you tightened more and more around him. "You gonna cum?" He asked with a tilt of his head,
"No, no." It sounded as if you were trying to convince yourself, shaking your head desperately. But it was futile, your body jumped as you felt him press against your clit hard, not wasting time to rub it in tight circles in a way your head spun, loud moans falling from your lips more often than you'd like.
"No?" He imitated you mockingly, you felt the knot in your stomach tighten, everything becoming too much so suddenly. And just as you felt like you were about to cum, something caught your attention.
The sound of a ringing phone, in particular. Making Nam-gyu stop, not fully, but go back to his initial slow and deep thrusts, dragging you away from your so desired orgasm.
A whine of protest left your lips, but it was immediately shushed as Nam-gyu clasped his hand over your mouth, fucking you slow and deep, your moans shushed against his palm (like this<3) "Shut the fuck up unless you want me to leave you here without coming." He threatened, and you nodded pitifully against his palm, a few tears slipping down your cheeks as you watched him pick up the call, setting it on speaker on purpose.
The phone was set down on the desk, a little far from you. But Nam-gyu really seemed to be set on not making this easy for you, he kept fucking you, just enough to make you reach the edge of your orgasm but never enough for you to actually have it.
Your quiet moans were muffled against his palm, biting your lip. He was so mean! if he wanted you to stay quiet, he could at least stop moving:(
"Nam-gyu, when are you coming home?" His wife called out through the speaker, she sounded a tad stressed out, the sounds of the traffic filling your ears, she was probably driving.
"Might take me a bit, do you need anything?" You wanted to understand how the hell he sounded so calm and steady, especially when you were quite literally crying and moaning against his hand. Especially when he was balls deep into your cunt. Did he have no shame?
But then, you couldn't really talk about shame. You clenched unintentionally around him the second his wife began speaking. It was dirty, prohibited, but it was arousing. You were getting off on it, as ashamed as you felt.
"I need you to buy groceries, and a few other things. I'm sending you the list." She sighed, the sound of her typing away on the phone barely audible through the speaker. "What are you even doing? you were supposed to be home like half an hour ago. Are you out smoking yourself dumb again?" she sounded mad, maybe you were right to deduce Nam-gyu's marriage wasn't going well.
"Yeah, yeah, whatever." He mumbled in reply, clenching his teeth as he stopped moving, looking at you straight in the eye for this. You were momentarily confused, but that look of confusion was straight wiped out of your face as he began to thrust faster, making you yelp against his hand, eyes rolling back in sheer ecstasy. "I'm grading some paperwork, you know? It's not exactly easy being a university teacher."
His jaw was clenched at the mention of smoking, and he was pounding into you more fiercely, in a more desperate kind of way that you couldn't hold your moans back, eyes rolling back as you cried out of pleasure. "No, I'm not smoking. I'll be home soon, I promise."
"Nam-gyu, what are those sounds?" She asked suspiciously, normally, your heart would have skipped a beat. But you were too drunk on the feeling of Nam-gyu's cock buried inside of you, rearranging your insides.
"Mm? oh, I'm grading a video essay." He lied blatantly, gritting his teeth to refrain grunts from getting out, sweat forming on his forehead. "Send me the list, I'll be out soon and I'll get the groceries. I'll hang up to finish grading these.. essays."
Silence filled the air for a brief moment, and then finally, a sigh was heard from the phone. "Whatever, don't take too long. And you better not come home smelling like cigarettes."
"Yeah, sure. No cigarettes, got it. I'll hang up now," He said through gritted teeth, a tense edge to his voice. Your moans eventually grew higher in pitch, every thrust making stars burst beneath your eyelids. "I love you, bye. See you later."
That was such a lie, but Nam-gyu let it roll out of his tongue with such ease. It was as if he wasn't pounding his own student into next week. But damn it, your moral senses of what was right or wrong completely vanished.
Once again, you felt yourself getting closer. Cunt spasming around him as you moaned and whined, tears leaving your eyes as Nam-gyu kept his hand on your mouth. "Shit— you’re.. fuck," he grunted, his hips faltering and stuttering. "You’re getting off on this, huh?" He scoffed, almost like a chuckle. "Being a homewrecker, clenching around me so sweetly while I talked to my wife. Getting turned on by nearly getting caught. Tch, you’re nothing more than a dirty slut."
You felt humiliated, but you knew he wasn’t wrong. You shook your head as a response, but the way you clenched around him as he said all of these things to you said otherwise. You could easily tell he was close too.
His hand easily slipped back to your clit, the double stimulation making you keen. Your free hand went to hold his wrist, only to be momentarily slapped away with the hand that was in your mouth before it flew back on it.
Your grip found the edge of the desk, eyes rolling to the back of your head, you finally came. Gushing around his dick, gripping his cock like you never wanted to let go. And he didn’t falter at least once, fucking you through your orgasm until he finally pulled out, shooting ropes of cum into your stomach.
By the time you came back to it, you realized you were practically trembling. Your whole body was buzzing, your ears ringing. That was by far the best orgasm you ever had.
From the corner of your eye, you could see Nam-gyu pulling his pants up and fixing his belt. He looked at you momentarily, smirking. "Your assignments were flawless, Miss L/n. I hope to see more of you," he began off, grabbing his coat. "Drop by whenever you need extra credit."
Maybe you would consider his suggestion.
