╰₊✧ your professor doesn’t like how close you’re getting to that playboy & calls you after class to discuss it┊2.3k words

contains: smut!! dom oliver & sub reader┊teacher/student relationship, age gap (unspecified but reader is early 20s & oliver is late 20s), established relationship (friends with benefits), jealousy, brat-taming (the good girl persona isn’t real), office sex & risk of getting caught, mentioned height difference, receiving oral, ooc probably (he’s bad with feelings), unrequited feelings & angsty rushed ending lmao

➤ author's note: i said “end of the week as in tomorrow”, but i was feeling generous!! i originally made prof and the reader have no relations other than teacher & student, but i struggled to create a dialogue so i made them friends with benefits and it got a lot easier! i did not plan to give it an angsty ending or to attach so much emotion to it, but it felt so right in the moment and i’m not taking it back 

you’re a good student, you know that right? you show up to every lecture without fail regardless of the weather and always take notes while asking questions along the way, which may seem annoying to some when in the later years of university, but you always help out others who missed class or don’t understand the material. you have a bright future ahead of you with how intelligent you are and how you’re so knowledgeable about the lessons of every class you’re in, he’s positive that he’ll see you on the news for making a historical breakthrough in whatever you’re studying and becoming one of the country’s richest women.

he doesn’t need to tell you this because he knows that you’re already aware of it, so why are you risking it all to hang out with some playboy who isn’t interested in anything more than a fun time and your body? as a professor, he’s seen and heard all that’s happened: how he asked you to help him cram for an exam, how a little friendship started blooming between the two of you, how you began to get more flustered when he got close to you, and most importantly, how he’s treated every other girl like that before breaking their hearts once he got what he wanted. you were so smart academically, but it seemed like you were too naive in matters of the heart.

normally, these aren’t issues that would bother him since he’s seen it repeated time and time again. although, he isn’t lying when he thinks your case is more important to him since he doesn’t want to see his best student fail due to a broken heart. he knows that your personal life is none of his business, but he’d be damned if he didn’t at least try to intervene. as your professor, it’s part of his job to make sure that his students are all going down the right path and to prevent them from being led astray!

this is far from the first time he’s called you to see him in his office after class, going over the essays that you asked him to review before grading or simply asking you about your plans for after college, but it is the first time he’s asked to see you out of worry. it’s actually been a while since he’s seen you one-on-one like this, the last time being three weeks ago. he balled his fit up tightly when he saw that boy loitering by his doorway after escorting you as you convinced him that he didn’t need to wait around for you and would be at the planned arrangement when the time came. he didn’t feel disappointed like he thought he would, feeling rather dejected and inexplicitly angry for reasons he couldn’t place.

“i noticed that your grades have been slipping,” oliver started as you took a seat, watching you tense up as soon as the words left his mouth. you probably realized too late that this conversation was going to happen before you could make any real change to avoid it, just living in dread for the past week or so. “do you mind me asking if there’s something that brought about this change?” you anxiously fiddled with the hem of your dress and he sighed, not wanting to scare you off, “and please, be honest so that i can help you in any way that i can.”

“i-i’ve just been… distracted… it’s nothing that you need to be worried about…”

well, that was pretty obvious, he didn’t exactly expect you to admit the truth right away. he wasn’t quite sure how he was supposed to go about this in a professional manner, but still plowed ahead to skip any unnecessary awkwardness and asked you to specify what the distraction was. he wasn’t even sure what the point of asking was since no student would ever spill their dating life to an authority figure even if they were asked (especially if they were asked), so he decided to just rip off the bandage. “listen, i know that it’s normal for students your age to be experimenting romantically with others, but you shouldn't be letting it distract you from your studies!”

you bit your bottom lip and felt your face getting hot, burning with embarrassment that spread from your nose to the tips of your ears. “my grades aren’t that bad!” you defended, “i’m still passing and turning in everything on time!”

“barely passing while turning in assignments a minute or two before the deadline,” he corrected, making you flinch. “i hate looking at everything academic going downhill for you— over some guy who peaked in high school and won’t be able to amount to half of what you are now too.”

you bit the inside of your cheek seeing your prim and proper professor suddenly being unprofessional by speaking poorly about one of his pupils even if it was the truth. he was only human after all, he didn’t have to like every single person who walked through the doors. besides, it’s not as astonishing as it may seem for him to let his guard down and show his true colors around you, and seeing as he was being transparent with you, there was no reason why you couldn’t do the same. “aww, what’s the problem? are you jealous?” you scoffed as you got up to pace around his room and meddle with some of his things like you owned the damn place, “now you know how i feel whenever you got all of those other girls trying to bend over your desk asking you to give them extra credit.”

all he could do was glare with annoyance in his eyes, wondering about just how these predicaments come about. it’s true that this is far from the first time he’s called you to see him after class, but it’s never been for any of the reasons he’d listed before. you never needed his help for anything in the first place— or at least you never needed his help for anything academic. most people don’t see anything special about your dearest professor aside from his handsome face and strait-laced attitude, but you’ve always seen more to him (and have seen more of him). with the current state of things, things were too easy and handed to you on a silver platter, so why not pass some time by having an illicit affair that allowed you to have some control over an attractive authoritative figure? it isn’t partying or doing drugs, but it gives you all the rush and fun you need by having him help you out with your needs.

it didn’t take too much time for oliver to figure out that you weren’t really the goody-two-shoes teacher’s pet you had everyone believe you were. he doesn’t have the foggiest idea why you act that way, but you certainly play the part well as he was none the wiser until you seduced him. he’s the teacher with higher standing and a name, yet instead of being the one with power in the relationship, you were the one with all the chips on your side. you love this little game that’s been arranged, one where you know exactly what he’ll do in response to any of your actions: calling you to his office after class to take out his frustrations on you. this was by far the first time that he’d called you over because of jealousy, and it certainly won’t be the last time.

“how about you give me some extra credit, professor?” you mocked, pouting your lips and batting your eyelashes as you pushed some of his belongings aside so that you could sit on one of the shorter sides of his desk. “since my grades are so low? pretty please?”

he has half a mind to ignore your flirty little comments and chew you out for purposely pissing him off just because you felt like he wasn’t giving you enough attention, but god, you’re such a vixen. it never mattered if you were wearing a hoodie and sweatpants or a crop top and short skirts, you somehow managed to be so enticing in all forms and lure him towards you like a moth to a flame. it might be your eyes, possessing a distinct mischievous sparkle that knew he didn’t have it in him to deny you.

when he grabs you by your collar and crashes his lips onto yours, you find it almost funny how weak he is to your charms and his envious nature. he always tells himself that it will be the last time he’ll be hooking up with you and will stop this inappropriate behavior that could ruin his life if discovered, but every time you’re presented to him, he finds his lust and true emotions spiraling into this very position at the end of it all. he wasn’t sure why he was constantly lying to himself about this issue all the time when it was plainly clear whether or not he is willing to admit it. while it’s only a fling for you, it might be something more to him despite the fact that it was so wrong for him to be with you. 

it’s too late to listen to reason or the little voice at the back of his head when you wrap your arms around his neck to deepen the kiss, requiring you to crane your neck upwards and also pull him towards by forcing him to lean down to your level due to his height. both of you were out of breath from the intense make-out session when he finally parted from your mouth, not saying a word or even bothering to look into each other’s eyes. it wasn’t needed when he already decided his next course of action and stood back up only to get on his knees, making quick work of pulling off your pants and underwear with a single swift movement.

you shivered at the sensation of cold air quickly being replaced by his hot breath ghosting over your cunt, barely making out a murmur about how none of the college boys you messed around with would ever do something like this. he was right, none of them ever did, and if they have, it was never half as good as how he made you feel with his experience and knowledgeable motions. hooking your legs over his shoulders with his head wedged in between to keep them separated, keeping his half-lidded eyes filled with lust on your face to watch the arrogant persona melt away into pure pleasure. 

there’s nothing that gives him greater satisfaction than watching you becoming undone while he licks long stripes along your sex before wrapping his lips around your delicate pearl and roughly sucking just to hear you squeal. now that he thinks about it, he isn’t sure if you locked the door behind you or if the possibility of someone walking in was very real. he would scare you about it, but you wouldn’t care if you were caught getting tongue-fucked by an instructor— you would probably flaunt the fact, especially if it were one of your flings or a girl who liked to flirt with him. (realistically, no one would enter before knocking and hearing his approval. besides, the place is relatively sound-proof and empty at this time.)

you tangled your finger in his brown locks and grasped onto them, not hard enough to revert his attention but just enough for you to find solace in a wave of euphoria. god, it feels like it’s been forever since you felt this sensation despite being a mere month, humming in delight every time his tongue toyed with your clit and hastily thrust into your entrance that was barely clenching around anything. your breath hitched as you threw your head back, voice caught in your throat and unable to let out anything but pathetic little whimpers instead of shameless moans.

his large hands gripped onto your thighs to hold you still, preventing you from rolling your hips or trying to grind on his face. not that he would mind you being more needy, but he wanted to keep complete control of the situation as he worked his mouth like magic until you cried out with your intense orgasm washing over you. your legs framing his head constricted for a moment, locking him in place before completely slacking from exhaustion. you usually would still have energy for another round or two after a few minutes of rest, but it’s been long enough without that you just slumped on the spot after letting go of him and placing them behind you on the wooden desk for support. 

you looked at him in a daze, still with a little devilish grin despite it all, watching him finally stand up and eyeing the sizable tent remaining in his pants, “do you need any help?” there wasn’t an ounce of care in your voice, not that there ever was when you were talking to him.

“no, i’ll handle it myself,” he stated simply. 

you tilted your head at him for a second before simply shrugging, “okay then, don’t say i didn’t ask!” there wasn’t an ounce of genuine care in your cheery voice.

“you can stay in here for now, just turn off the lights and keep quiet in case someone shows up.”

“aww, leaving already?” 

he remained quiet as you chuckled, putting his olive green coat on before departing to the bathroom to take care of himself. at least that was the original plan, any contentment he had during the whole ordeal quickly disappeared once it was all over, leaving nothing but a heavy weight on his chest that overpowered any feeling of horniness that was there. maybe he would just head home for today, rethinking what on earth he was doing. wishing for a student who didn’t see him as anything more than someone to pass the time with, he knows that he’s a deeply pathetic man regardless of how esteemed he is in the eyes of everyone else.
