Work Text:

When Jeongguk decided to start teaching, someone should’ve prepared him for students like Kim Taehyung. But no, no one did.

He genuinely loved his job. He got his PhD. in English language and literature and immediately started teaching at the same university. He liked teaching but right his first year of work proved to be hard thanks to a certain student.

Jeongguk knew Taehyung from when he was still a student too but since there was like five years difference between them – Taehyung was a senior now - they never really talked or anything. He just spotted him couple of times in the hallways because, well, Taehyung was very hard to miss. Not only because he was very loud most of the time and because he was changing hair colours almost every month but because of his appearance.

Taehyung was a cross dresser and Jeongguk never knew that he had a thing for guys in skirts, booty shorts, crop tops, heels or thigh-highs but here he was. And the fact that Taehyung was one of the most gorgeous people that Jeongguk’s ever laid his eyes on wasn’t helping at all. He was just so perfect, his face was symmetric and soft but somehow sharp at the same time. He liked wearing make-up, usually pretty light, but that only was emphasizing his beautiful features even more.

Jeongguk could deal with that, he really could, he could just admire Taehyung from afar and go on with his life but Taehyung took a liking in him since the first English lesson they had together and Jeongguk was suffering.

 S.U. F. F. E. R. I. N. G.

Because Taehyung was a fucking tease. He was very well aware of his beauty and knew that people liked him and he was taking a full advantage of that. It helped him gain a confidence – that was borderlining cockiness more often than not – and when he set his claws in someone, he didn’t let go until that person fell for his charm. And unfortunately for Jeongguk, that person was him.

Today was just usual lesson of contemporary English which was one of Jeongguk’s most favourite courses. It was usually nice and laid back, they were conversing a lot, talking about modern language and slang and it was fun.

But Taehyung was a part of the class which was making Jeongguk’s job more difficult. Now don’t get him wrong, he actually liked Taehyung, he was really smart and he was eager to learn new things and conversed a lot but he also sometimes had weird and inappropriate comments that were making Jeongguk sweat. Today was one of those days when Taehyung decided to be a fucking tease.

He was sitting there, in a first row, in tiny jeans shorts, converse high and crop top. Just recently he dyed his hair silver which was only making him look even more ethereal. Jeongguk’s eyes kept slipping to his exposed slim, soft tummy and long legs much more than he’d wish. But that wasn’t apparently enough torture for today.

“Jeongguk-ssi!” Taehyung raised his hand. Jeongguk wanted to keep the atmosphere in his class friendly and since he was young, he didn’t dwell on the highest honorifics.

“Yes, Taehyung?” the professor looked at the other.

“Can you tell me how do you say ‘My professor is hot’ in English?” Taehyung grinned innocently, earning laughs from the class. Things like these weren’t uncommon at all.

“You know very well how to say that, that’s like the most basic grammar, Taehyung,” Jeongguk replied calmly.

“I just wanted to make sure, in case I wanted to use it,” the younger threw a leg over the other, poking his tongue out little bit.

“Let’s just go back to what we were doing, okay?” Jeongguk ignored Taehyung and started where he was interrupted.

He thought that Taehyung was done for today, it wasn’t even that bad but once the lesson ended, the student made his way to the professor’s desk. He was swaying his exposed hips, small smirk playing on his lips.

“Do you need any help, Taehyung?” Jeongguk looked up, suppressing an urge to sigh.

“I was actually wondering if you could help me with something, I feel like there are some things I didn’t get well the last time, so I was hoping you could make time for me in your office hours,” Taehyung leaned against the desk, sticking his ass out a bit too much. Jeongguk cleared his throat, looking at the last students leaving the lecture hall.

“I don’t think you have problem with anything, you always perform well,” the professor said. He didn’t want to be rude and refuse help to any of his students but he was pretty sure that Taehyung would just ask him how to say ‘I wanna suck your dick’ in English. Even though Jeongguk was pretty sure that Taehyung already knew every expression and slang for that.

“But, prof, I really need a help,” Taehyung pouted cutely and Jeongguk was lost.

“Fine, if you believe there is something you need help with, come see me today at five,”

“You’re the best, Jeongguk-ssi!” the younger beamed with a small wink and left. Jeongguk leaned back in his chair as students for another lecture started coming in. He didn’t know what Taehyung was planning but he had a feeling that it was nothing good. He wouldn’t even care about his teasing and flirting, he actually thought that it was funny most of the time. The problem was that he was really fucking gay and really fucking attracted to Taehyung and he’s been trying his hardest to keep everything professional. But it’s been months since he started teaching here and it was getting harder and harder. He just had to wait till Taehyung graduates in couple of months and he’ll be fine.

Later that day, when Jeongguk was sitting in his small office, there was a knock on the door. He was confused for a second before the silver head peaked in. He forgot about Taehyung and damn, now he wasn’t ready.

The student greeted him and walked in, sitting on the chair in front of his table.

“So, Taehyung, what can I help you with?” Jeongguk leaned back in the chair, looking at the other with confident expression, not wanting to show any discomfort.

“Well, we were talking about the abbreviations that are often used on the internet the other day and there are some that I don’t know. Like, I’ve seen a lot of them and figured what they mean but some of them are unclear,” Taehyung started shyly.

“What exactly it is you didn’t understand? I wrote the abbreviation and the full meaning next to it on the board,” Jeongguk suppressed an urge to roll his eyes.

“I was busy,” Taehyung fiddled nervously with his fingers, looking down on his lap.

“What were you busy with?”

“Staring at you,” the younger grinned, all innocence and shyness gone: “You looked really damn good that day, Jeongguk-ssi, your biceps were popping so nicely and when you turned your back to the classroom, I just couldn’t focus because damn, those pants were tight.”

Jeongguk just stared at the student, completely taken aback by his straightforwardness. He found out long ago that Taehyung was shameless but now when they were alone, it was a next level.

“You should learn how to focus, Taehyung, instead of staring at my ass. I know it’s hard to resist but you are in college, you need to focus,” Jeongguk shot back. He didn’t know where it came from, maybe it was because he was kinda tired of Taehyung always teasing him and he always had to keep straight face and ignore him in front of the class but now they were alone and two can play this game.

“But it’s hard, Jeongguk-ssi, no one ever prepared me that there could be such hot professors in college, I always thought that all of them are old, weird and boring,” Taehyung pouted but he had sparkles in his eyes, obviously enjoying the situation.

“So what abbreviations you didn’t understand?” Jeongguk changed the topic to safer area.

“It’s better if I showed you, can I use your computer?”

“Sure, go ahead,” the professor nodded but quickly realized his mistake. Taehyung jumped on his feet excitedly and circled the desk. He rested his elbows on the desk right next to Jeongguk, sticking his ass up in the air.

He started searching something on the internet while Jeongguk just sit there, trying to breathe and think clearly. Taeyhung wore a light, nice perfume and his skin looked so soft from up close. He forced himself with all he’s got not to turn his head and stare at the perky ass.

Taehyung showed him some abbreviations and Jeongguk explained them to him. When he could focus on English and teaching, it was much easier to ignore the fact that their arms were almost touching.

“You are my most favourite professor, Jeongguk-ssi,” Taehyung gave him a bright smile when they were finished. Jeongguk was low-key scared what the younger was gonna do but to his surprise, relief but also slight disappointment, Taehyung just went back to the chair and grabbed his bag.

“See you in the literature class, prof, have a nice evening,” Taehyung winked at the older with a small smirk. Jeongguk just nodded dumbly and watched the other leave. Well, he survived and that was surely a good thing.


Jeongguk went on with his job. Sometimes Taehyung wasn’t making things easy for him but he was trying to ignore him as much as possible and it was fine. Until one day when he spotted Taehyung in a hallway.

The silver-haired student was leaning against a wall, talking to his friend Park Jimin. Taehyung looked great as always, he had tight skinny jeans that were hugging his thighs and butt nicely and he was rocking heels and a light top.

Jeongguk’s blood almost froze in his veins and he felt an ugly feeling deep inside his stomach when he watched the interaction between Taehyung and Jimin. He was stopped by a fellow colleague and the professor was talking to him but he paid barely any attention to her. His eyes kept slipping to the two students that were standing only couple of meters from them.

Taehyung was leaning to Jimin every now and then, whispering something into his ear and giggling cutely. Jeongguk couldn’t shake off the feeling that he was flirting with him. He clenched his jaw when he suddenly noticed Taehyung bringing his hand and slapping Jimin’s ass playfully and then groping it little bit.

“Everything alright, Jeongguk-ssi?” the professor’s voice snapped him from his trance.

“Yeah, sure,” he smiled at her, looking back at Taehyung after couple of seconds. He was whispering something to Jimin again but then his eyes landed directly on Jeongguk and he smirked. And Jeongguk knew immediately that the younger was fucking with him. Damn Kim Taehyung, why did he have such impact on him?


Jeongguk started noticing that whenever he was anywhere near Taehyung, the student seemed to tease him. He did that before but in different ways. He seemed to catch up on one of Jeongguk’s negative sides – jealousy – and he was taking full advantage of it, always all over someone.

It was even worse today. Jeongguk was just sitting at the table in the uni cafeteria with couple of other professors when suddenly Taehyung came out of nowhere, heading to them. Jeongguk gulped, not knowing what the younger man was going to do in front of his colleagues but he couldn’t say he was relieved when the boy went to Namjoon instead of him.

“Hey, prof, I was wondering if you were free this afternoon. There is couple of stuff I wanted to ask you about the last lesson,” Taehyung leaned his elbows on the table in front of Namjoon, pouting cutely and taking his signature pose with stuck up ass, that was nearly in Jeongguk’s face.

“Yeah, sure, Taehyung, I am free this afternoon so you can come to my office whenever you need,” Namjoon smiled at the student. He was a bit confused by Taehyung’s behaviour.

“You are the best,” Taehyung giggled cutely, giving Namjoon a flirty eye. Jeongguk was watching the whole scene, gripping chopsticks between his fingers, clenching jaw. The thought of Taehyung going to some professor’s office wasn’t sitting well with him. When he imagined the boy flirt with Namjoon the way he did with him, his blood was almost boiling.

“Hello, Jeongguk-ssi,” Taehyung turned his attention to him, looking at him smugly. Jeongguk knew that he was doing it just to rile him up and well, it was fucking working. He seriously had no idea how long he will be able to hold his shit together.

Taehyung left and Namjoon and Yoongi turned to Jeongguk.

“What the hell was that?” Yoongi quirked an eyebrow at the younger.

“I don’t know what you’re talking about,” Jeongguk shrugged.

“Please,” Yoongi rolled his eyes.

“Seriously, what was that? I mean, Taehyung is friendly and all that but he’s never acted like this before, that was weird,” Namjoon looked like a lost puppy.

“He’s doing it to rile me up,” Jeongguk snapped with a sigh: “He’s been flirting with me basically ever since I started teaching here and it’s only getting worse.”

“I was wondering what that shit-eating grin he gave you meant,” Yoongi snickered: “Well, what are you gonna do about it?”

“There is nothing I can do about it. He is a student, I am a professor,”

“But you want him,” Namjoon stated matter-of-factly.

“Hell yeah I do!” Jeongguk groaned: “He’s gorgeous and he drives me crazy but I don’t wanna get myself or him in trouble.”

“Well, he’s graduating in couple of weeks and as far as I know, he isn’t continuing his studies here. So basically all you have to do is wait till he’s out of school and then you can just fuck him,” Yoongi shrugged nonchalantly.

“It would still be weird,” Jeongguk grumbled.

“Why? He won’t be a student anymore and there is only like a five years age difference between you, it’s not that bad,” Yoongi shrugged again.

“The question is if you will be able to resist for couple more weeks,” Namjoon chuckled.

“I have no fucking idea, hyung,” Jeongguk groaned in frustration again. He was already complimenting himself for making it that far. He could stand couple more weeks and once Taehyung graduates, he could just ask him on a date. Because the truth was, he didn’t wanna just fuck him, he wanted to get to know him better, take him on a date and maybe start something between them. Yeah, just couple more weeks.


Jeongguk’s resolution went to hell only couple of weeks later. It was during his last lesson with the seniors, they had the last week of lessons and then their break to study for finals started.

Taehyung was sitting in the first row as usual and he wasn’t making things easier for Jeongguk at all. He was wearing a short schoolgirl uniform skirt with thigh-highs and heels while his torso was covered in white shirt. His silver hair was a bit messy and his eyes were emphasized by light smokey shadows. He looked downright sinful.

He was sitting his leg thrown over the other, sometimes alternating between them as he was watching the professor the whole time. To say that Taehyung was desperate was an understatement. He was sure he’d break Jeongguk by now but the professor had a good resolve. And his graduation was nearer by day which meant that he wouldn’t see Jeongguk again after that. This was the last lesson and he had to do something. So he just decided to be bold and go for it.

When the lesson ended, everyone packed, saying their goodbyes to the young professor. Taehyung was packing his things slowly on purpose and he could feel Jeongguk’s gaze on him. When he was done, throwing the bag over his shoulder, he came over to the desk where the professor was sitting.

“Well, I guess this was our last lesson, Jeongguk-ssi,” Taehyung smiled tightly, suddenly feeling a bit choked up. He didn’t just wanna get into Jeongguk’s pants, he genuinely liked him, he was a great professor and he always loved lessons with him.

“At least I won’t have to deal with you anymore,” Jeongguk said quietly but there was no malice in his voice, more like teasing. Taehyung grinned and put down the bag. Then he shuffled to lean his ass against the desk so he was standing between the desk and Jeongguk who was sitting in the chair. The older man looked up at him with slightly hooded eyes and despite Taehyung being the one standing up, he felt so small under that gaze right now.

“We both know, prof, that you will miss me,” Taehyung spoke up teasingly, licking his lips and looking down at the older man when he finally snapped from his short daze. Suddenly Jeongguk stood up so he was only couple of inches from Taehyung. The younger gulped, suddenly a bit nervous. Jeongguk was still hovering over him little bit, even though Taehyung had heels.

Taehyung stopped breathing when Jeongguk suddenly put his hands on each side of him so he was basically caging him between himself and the desk. His arms were straining against the thin fabric of the dress shirt that was rolled up to Jeongguk’s elbows, revealing the prominent veins on his forearms. He was staring at Taehyung with intense look. Taehyung could see the internal battle going on inside Jeongguk’s head, he knew that Jeongguk wanted him but he was trying to hold back.

“It was our last lesson, Jeongguk-ssi, let go,” Taehyung breathed out softly, staring into the other’s eyes and those words were like magic, snapping something in Jeongguk. The professor’s gaze darkened and before Taehyung could process what was happening, he crushed their lips together.

Taehyung was taken aback for a second, because holy shit it was really finally happening, but he started eagerly returning the kiss soon. It was rough and messy and soon Jeongguk was licking into his mouth and Taehyung was moaning softly at the feeling. He’s been imagining this for moths, Jeongguk kissing him, caging him against a wall or some furniture and Taehyung’s head was spinning because none of his fantasies came close to the reality.

“Fuck, Taehyung, you’re driving me fucking crazy,” Jeongguk groaned deeply as he broke the kiss, watching the younger boy: “You have no fucking idea how much I wanna ruin you after all those months of teasing.”

“Then do it, Jeongguk, please, ruin me,” Taehyung nearly whimpered and he’d be embarrassed if he wasn’t so turned on right now. Jeongguk growled and crushed their lips together again, kissing the student like there was no tomorrow. Taehyung had nice lips and they felt and tasted incredible. He broke the kiss after a minute and attached his mouth to Taehyung’s neck instead, biting and marking the soft skin.

“Fuck, Jeongguk please,” the younger moaned as the older brought their bodies together and grinded against him. He was already so hard under his skirt and he got even more turned on when he felt Jeongguk’s prominent bulge in his slacks.

Before he would lose himself in pleasure, Taehyung reached down for his bag and quickly found what he was looking for. He put a bottle of lube and a condom on the desk next to him.

“What a naughty boy, bringing these to school,” Jeongguk chuckled darkly and attached his lips back to Taehyung’s neck, mumbling: “Why did you bring them, baby boy?”

Taehyung’s back arched and a filthy moan escaped his lips at the pet name and the slight humiliation. Jeongguk just smirked against his skin, he knew that Taehyung would like this. Not to stereotype or anything but someone who loved cross dressing and was so flirty had to like this.

“Answer me, baby boy, why do you have a lube and a condom with you here?” Jeongguk grabbed his hair tightly and made him look at him. Taehyung looked so fucked out already just from the way he talked and looked at him.

“I wanted you to fuck me,” Taehyung whimpered.

“Oh, is that so, baby? Did you hope I’d bend you over the desk here and fuck your pretty, tight ass? Fuck you here where anyone can walk in on us so they’d see what a hungry little slut you are for my cock?” Jeongguk whispered against Taehyung’s ear as his hands squeezed Taehyung’s plump ass through the fabric of the skirt.

“Yes, fuck, Jeongguk, yes!” Taehyung cried out almost desperately, pushing his ass into the touch.

“Since you like sticking your ass in front of me all the time, I think you’ll like this,” Jeongguk said quietly. He kissed Taehyung passionately for couple of seconds before he spun him around and slammed him down on the desk so he was standing on the ground while his chest was lying on the furniture. He was panting at the rough treatment and the thought of him lying there in front of Jeongguk, completely in his mercy was turning him on even more. He just knew that Jeongguk would be like this, rough and dominant and he loved every second of it.

Jeongguk pushed up the short skirt and sucked in a deep breath, cursing quietly. Taehyung’s perky ass was covered in a red lace and his dick actually twitched in his pants at the sight.

“Fuck, baby doll, I always wondered what you wore under those pretty skirts, I knew that it wasn’t some boxers. So beautiful,” the professor got out in raspy voice, kneading the cheeks appreciatively.

“Those are not even my prettiest ones,” Taehyung giggled over his shoulder.

“Can’t wait to see the other ones then,” Jeongguk cooed. Taehyung shuddered at the silent promise. They haven’t done anything yet but Jeongguk obviously intended to repeat it, this wasn’t just one time thing and Taehyung was more than happy with that.

Jeongguk pulled the panties down so they were resting around Taehyung’s thighs. The sight in front of him was downright sinful. Taehyung lying sprawled over his desk, his long legs covered in the thigh-highs, panties resting stretched on his thighs and his exposed ass and pink hole right in front of him.

“Shit, kitten, do you feel how hard you make me?” Jeongguk groaned and to prove his words, he grinded his clothed erection between Taehyung’s cheeks. The younger moaned and pushed his ass back, seeking more.

“Gonna fuck you so well, princess, gonna stretch you with my fingers until you beg for me and then I’m gonna pound you into the desk and then come all over your pretty ass. Would you like that?” Jeongguk spoke up deeply as he started coating his fingers with the lube.

“God, yes, Jeongguk, please!” Taehyung whimpered, shutting his eyes and panting at the promise. His whole body jerked when he felt fingers gently teasing his hole. Thankfully Jeongguk didn’t tease him for too long and pushed slowly first finger in.

“Shit, baby, did you finger yourself?” Jeongguk groaned when he wasn’t met with any resistance and immediately pushed a second finger in with an ease. He started fucking the fingers in and out slowly. Taehyung mumbled something inaudible.

“Louder, doll, let me hear you,” Jeongguk smacked his ass, earning a cry of pleasure.

“I fingered myself this morning thinking about you!” Taehyung sobbed as the older started fucking him with the fingers without any mercy.

“Is that right? What were you thinking about, baby boy, tell me!” Jeongguk groaned, pulling the fingers out and slipping three back.

“I was-ah…” Taehyung shuddered, taking a deep breath as the professor fucked him vigorously: “Was thinking about your fingers stretching me.”

“What else?”

“Was thinking about you fucking my throat until I couldn’t speak,” Taehyung babbled against the desk: “Was thinking about you lifting me up and fucking me against a wall until I couldn’t walk!”

“Maybe some other time, princess,” Jeongguk chuckled and smacked Taehyung’s ass lightly as he pulled out the fingers.

“Ready for my big cock to split you open, baby?” Jeongguk grunted as he tore the package with the condom open and rolled it on himself. He didn’t even bother undressing, he just pushed his pants and underwear down little bit.

“Fuck, yes, give me your huge cock,” Taehyung nodded eagerly as he looked over his shoulder and saw the package Jeongguk was carrying. He wasn’t disappointed, he knew that he’ll get it good.

Taehyung’s head fell back on the desk when Jeongguk lined himself up with his entrance and pushed little bit so the head slipped inside. The younger was moaning shamelessly, the sounds were carrying over the big, empty classroom and it was already obscene.

Jeongguk pushed slowly inside, inch by inch until he finally bottomed.

“Shit, baby doll, so tight,” Jeongguk groaned and lied down against Taehyung’s back, pressing open mouthed kisses to the back of his neck. Taehyung moaned when the older started slowly rocking his hips in and out and turned around to seek his lips. Jeongguk took the hint and kissed him messily in the awkward angle.

“Fuck, Jeongguk, you are so big, shit, I love your cock so much, fuck me please,” Taehyung babbled incoherently, pushing his ass back to get the other deeper and to get him to move faster.

“I’m gonna destroy that pretty, slutty ass of yours. Gonna punish you for all those months of teasing,” Jeongguk growled and bit Taehyung’s earlobe, before he pulled himself back from the younger so he was standing properly.

“God, yes, Jeongguk, punish me, fuck me like the slut I am,” Taehyung groaned. Jeongguk gripped his hips tightly and started pounding into him without any warning. Taehyung started shamelessly screaming in pleasure, the desk was rocking under him with the force of the powerful thrusts and he was slowly losing his mind. The sounds of skin slapping against skin were filling the room, along with their moans and groans and Jeongguk knew somewhere at the back of his mind that this was risky because anyone could walk in and they’d get in trouble but the thought of someone walking in on them, seeing him fucking Taehyung like this was making him even more aroused.

“So close, please,” Taehyung whimpered with tears in his eyes because Jeongguk was nailing his prostate with each sharp thrust. The older sped up his movements to the maximum, ramming into the boy under him, making him sob against the desk.

“God, kitten, gonna come so hard. I’ll come all over your pretty ass, make you all dirty,” Jeongguk moaned raspily, fucking into Taehyung with his remaining powers. His thrusts were getting sloppy as he was nearing his release.

“Yes, shit, come all over me, cover me with your come, Jeongguk,” Taehyung nodded feverishly. Jeongguk groaned, throwing his head back. He wrapped his hand around Taehyung’s neglected cock, hanging between his legs and that was enough for the younger to trip over the edge. Taehyung clenched, cried out brokenly and came over Jeongguk’s fist and the floor under the desk.

“Shit, princess, fuck,” Jeongguk groaned as he felt the student clenching hard around him. His vision went almost black but he managed to pull out last second. He quickly pulled the condom off in time to paint Taehyung’s ass with white ropes. The younger whimpered at the feeling, completely fucked out, tired but content.

Jeongguk bent down when he came down from his height and kissed Taehyung slowly, whispering praises into his ear after.

“I hope we are gonna repeat this,” Taehyung got bold and asked.

“I’d love that,” Jeongguk nodded with a smile: “But after you graduate.”

“But I don’t think I can wait for another month,” Taehyung pouted.

“You will be busy with studying, believe me, you won’t even remember me,” Jeongguk snorted: “But if you want to, I promise that once your finals are over, I’ll take you out on a proper date and then I’ll reward you with a good fuck in my apartment, mm?”

“That’s what I call a motivation to pass the finals,” Taehyung snickered and trapped Jeongguk’s lips in a lazy kiss.
