Work Text:
It's not that Yoongi dislikes Professor Kim. It's just that everyone agrees that Professor Kim is the scariest professor in the entire school. He's not mean or cruel, but he is strict and stern. He knows what he wants and what his students are capable of. He doesn't expect you to be the best, but he expects you to be your best. Therefore, disappointing him strikes fear into the hearts of every student who passes through one of his classes, and Yoongi is no exception.
He's just much better about hiding it than everyone else.
He's also lucky he's not taking one of Professor Kim's classes requiring hands-on participation, like photography or drawing. He's taking an art history class focusing on the Renaissance as an elective, his only one this semester. It means that this is the class that has the least impact on his future, while also making Yoongi wonder why in the world out of all the teachers, Professor Kim is the one he most wants to impress, and out of all the classes, this is the one he most wants to succeed in.
He doesn't know the answer, and he's given up on trying to figure it out. He simply accepts that Kim Taehyung is a man everyone wants to impress, and it's useless to pretend otherwise. He's not special for this. Even the other teachers don't seem to be immune. Only two are. Professor Park Jimin, a professor in the math department, and Professor Jeon Jungkook, a professor in the music department. Both of whom Yoongi has classes with. Professor Park teaches calculus, and Professor Jeon teaches music theory. He doesn't feel the need to impress them like he does Professor Kim, but they're also the only other teachers that Yoongi does feel any desire to impress.
So much so that he has arranged meetings with both of them to discuss his future; he's in his junior year, and he knows that he needs to get serious about deciding if he wants to continue to grad school. His double major in business and music will serve him well if he decides to enter the career force right out of school, but having an MBA or an MA would help even more.
(And he could also have a couple more years before facing the world without the safety net of academic validation to keep him sane and settled. He doesn't tell either of his professors that, but he thinks they can tell. He's happy they don't seem to judge him for it.)
He's leaving Professor Jeon's office when he realizes where Professor Kim's office is. No one goes to physical office hours for the man. He doesn't have any setup. He'll set up an appointment at any time, some people stating that they've had appointments at midnight or even later, thanks to their schedule, and he's perfectly fine with it. He just doesn't seem to like students showing up at his office without notice, and thanks to his flexibility and a healthy dose of fear, no one says anything about it.
Yoongi knows he shouldn't do anything besides nod and move on, but his legs feel frozen because the door is open just a crack, and inside, he hears noises .
The sound of fucking to be precise. Someone either extraordinarily brave to be fucking in Professor Kim's office, or much more likely, Professor Kim is fucking someone in his office. Someone who is making little punched out sounds of pleasure, whimpering as Professor Kim grunts, the sharp scent of alpha finally registering in Yoongi's mind, mixing with the sweet delicacy of an omega. Personalized by Professor Kim's whiskey and lemon, strong and sturdy and intoxicating, and mixing in with the scent of cherries and sea salt, a scent that Yoongi can't place but smells fucking amazing.
He wants to see the omega who has Professor Kim acting so recklessly, who smells so wonderful, and before his common sense can do anything to save his sorry ass, he's inching closer to the door to peak inside.
He thought whoever it would be would be someone Yoongi didn't know. It could be anyone, even a secret spouse that Professor Kim hid away.
But instead, it's Kim Seokjin, sprawled over a desk while Professor Kim thrusts four fingers inside of him, looking debauched while the professor looks unfairly put together. The school bad-boy, as eye-roll inducing as that sounds, but there's no other word to describe Seokjin except maybe trouble and delinquent and asshole. An alpha. Except not, because Seokjin's scent has always been muted, nothing like the rich trueness of this moment. Cherries, sea salt, and omega .
Yoongi feels like he's about to collapse. He takes a deep breath, his mouth watering, and stumbles into the door frame, knocking it wide open. Professor Kim looks up with fury in his eyes, though Seokjin seems to be too fucked out to do anything other than whine at the brutal pace being disrupted. Yoongi reacts on instinct. He slides into the room, slamming the door behind him and leaning against it as he stares at Professor Kim.
He thinks that he's going to flunk Art History.
Professor Kim keeps his eyes on him, and Yoongi doesn't know his thoughts. He's picking up the pace again, bending Seokjin's legs in such a way that Yoongi didn't think was possible, that he had no idea a person could be that flexible, and certainly not Seokjin. But now that he knows, it's all he can think about. He's going to close his eyes every night, and he will see this beautiful sight.
Living another day is in question, however, because Professor Kim might kill him. Except maybe not. Because now the professor is smirking as he slowly pushes his pinky into Seokjin's body, the omega's back arching and toes curling as he tries to breathe through the sheer overpowering pleasure that he must be feeling. Yoongi wants to know what it would be like to cause that pleasure in such a beautiful face. His hands itch with the desire to fuck Seokjin until the omega doesn't even know his name, like the way that Professor Kim is fucking him now.
He knows he wouldn't look as casual as Professor Kim does. He pulls Seokjin apart without seeming to care how he will put him back together again. He just fucks him like this is nothing. It probably is nothing to him. That realization makes Yoongi's knees buckle, falling against the side of the door and making him realize that his dick is more erect than it's ever been in his life. Truthfully, he didn't think it was possible for it to feel this hard.
He thinks that he should look away. Scratch that, he knows that he should. It's not right. Seokjin doesn't know that he's here. But he can't move, and Professor Kim takes it upon himself to ensure Seokjin knows what's happening. He removes that pinky from him and flips him around like he means nothing, the muscles in his arms barely tensing. The omega mewls -- fucking mewls -- blinking around until his eyes land on Yoongi and he turns so pale that Yoongi worries that somehow all the blood has left his body.
"Wha'?" Seokjin slurs out. "Hyung, what's-?" He tries to push himself up on his arms, but they're too weak to hold him up. He slams back down to the desk, and Taehyung continues like nothing strange happened.
Yoongi really should leave. He doesn't want to.
"Tell me, baby," Taehyung croons. "What do you think? Do you want to invite Yoongi-ssi to join us?" He slowly starts to grind into Seokjin, making the omega's mouth drop open in pleasure and leaving him unable to think. It takes Seokjin a minute and a whole hell of a lot of blinking before he, miraculously in Yoongi's eyes, nods.
"Sure," he whimpers, fingers curling into the desk. "He can join if hyung wants."
Yoongi doesn't need to be told twice. He's up and moving towards the desk, looking down at Seokjin like this is the first time he's ever seen him, which is in a way. He never thought it would be possible to see him like this. The idea of Kim Seokjin as an omega felt laughable just twenty minutes ago, but now, Yoongi cannot imagine Seokjin as anything but an omega. It feels meant to be. Those long legs, milky and toned, kneeling on the desk as he struggles to keep his noises inside because he doesn't want to let them out and have anyone discover them. Has anyone else discovered them? Has the door been cracked other times in the past?
Though Yoongi wonders if he's terrified of the discovery or if he just doesn't want to discover how much of a slut he can be because the way that he's spreading his legs for someone that he barely knows and seemingly dislikes? His body craves a knot and doesn't care how he gets it. And really, that's okay. Yoongi finds he doesn't care about the details, such as whether he likes Seokjin. He just wants to be in that tight, hot body.
Later, he'll sit down and think about how he walked into the plot of a porno, one that he would scoff at and mock Hoseok and Namjoon for watching. He'll never be able to do that again because he knows it can happen. He can be brought into a threesome by the teacher he respects the most and an omega who is begging for Yoongi-oppa to fuck him.
However, in all honesty, Yoongi doesn't remember much after Professor Kim invites him over and Seokjin calls him oppa. He doesn't know how the omega knew about his kink or if he was just taking a lucky guess, but the brat dared to smirk as he stretched his back, looking at him through half-lidded eyes, and if he was still able to play, then he certainly wasn't being fucked hard enough.
Yoongi will fix that. He has three fingers in Seokjin already. He's warm and wet. He can feel the stickiness of Professor Kim's cum inside of Seokjin and he doesn't even think before he bends down to lick some of it that's trailing out of the omega. It brings the most beautiful moan out of him, and while Yoongi would love to spend more time eating him out, his entire being is shaking with the desire to get deeper inside of Seokjin. He can feel how his hole sucks his fingers in, and he's desperate to feel that around his cock.
He makes quick work of his pants, clambering onto the desk and pressing the head against Seokjin's hole, and it doesn't feel real how easily he's able to slide into him. It feels like it should be illegal, that he shouldn't be able to experience pleasure this good, but he tells that part of himself to fuck off and to let him enjoy life.
He hears the creak of the desk chair as Professor Kim sits down. Yoongi can see his hands crossed on his lap when he glances at him, watching the two with half-lidded eyes as he smirks. Yoongi feels like he's being appraised. He trusts Professor Kim enough to know that his performance in school won't be judged on how well he fucks Kim Seokjin, but he can't stand the thought of being found wanting. He wants to prove to Professor Kim that he can fuck Seokjin just as well as he can. Make him just as much of a mess. And if he can't, then Yoongi will fuck him again and again until he is that good.
And to do that, he needs to focus all his energy on Seokjin. He focuses his thoughts away from the older man and towards the beautiful, panting omega underneath him, who is wrapping his long, pretty arms around Yoongi's neck and pulling him down closer to him, turning his mouth to try and kiss him and ultimately just landing a sloppy kiss on his cheek.
It's adorable, so endearing that Yoongi has to laugh as he gently grips his chin and guides Seokjin's mouth to his own, pressing their lips together. It's not quite making out, Seokjin lacking the ability to coordinate, but he lets Yoongi do what he wants, run his tongue against his own, against his teeth, tasting Seokjin and what he knows must be Professor Kim.
He's delighted to find out that they both taste wonderful.
He can hear Professor Kim's heavy breathing, the slick sounds as he fucks his hand, and Yoongi wants to watch him, but he decides that should be for another day. Hopefully, there'll be another day.
Today, he's just going to focus on fucking Seokjin. On how soft and slick he feels inside, how wet he is, and how one day, Yoongi wants to push Seokjin down on a bed and eat him out for hours. The amount of slick that's coming out of the omega and the amount of lube that has been applied have made the desk a wet mess that Yoongi might find gross at another point. Truthfully, it's a miracle that he doesn't think it gross now. But Yoongi is discovering that Kim Seokjin can make anything that might seem gross into something beautiful. If there weren't a wet mess of lube and slick and spit and semen, then Yoongi wouldn't be able to see just how Seokjin can shine when the lighting hits him just right.
No wonder Professor Kim had to break the ethical guides to fuck his student. He's an artist. Of course, he has to appreciate the art that lives and breathes around them.
He stands up on shaky legs and gets his pants back on. By the time he's finished dressing, Professor Kim is cleaning off Seokjin, whispering soft words about how good he is. How pretty and perfect and he took two cocks like a champ. Oppa is so proud of his baby. His baby should be proud of himself. The words make Seokjin beam with pride, and he looks so pretty that Yoongi ignores the desk that desperately needs to be cleaned to join in on the Seokjin praise. He kisses the omega's face and lifts him with shaking arms to take him to the couch and get him dressed. All the normal fight and bluster he associates with the man is gone, replaced by the image of a docile kitten who needs to be pampered. Yoongi thinks he's two seconds away from purring, and his heart bursts with pride at the thought. Omegas only purr when they're very comfortable, and the idea that he has done that for Seokjin? It makes him want to shout it from the rooftops.
He bites down on that impulse. Especially when Professor Kim finishes cleaning up the desk and comes over to the couch to kiss Seokjin again, whispering how pretty he is in his ear.
Yoongi doesn't know what to make of it as he steps back and looks at the two of them. Professor Kim glances at him and smiles. Not a smirk. But a genuine smile as he gestures towards the spot on the other side of Seokjin. Yoongi doesn't need to be told twice as he sits down, Seokjin leaning against him, and the weight of the omega is enough to make the exhaustion hit him. He yawns as his eyes flutter close, and he's vaguely aware of Professor Kim covering the two of them with a blanket.
He'll talk to him later. He'll speak to both of them later because he's still struggling to figure out what exactly happened, and he didn't expect this when he woke up in the morning.
But he's certainly not disappointed that it did.
