One late afternoon, when the two of you were alone in the lab, you pushed your luck. It started with a subtle brush of your breasts against his arm while pretending to look at his computations. He froze, but he didn’t move away. Encouraged, you pressed harder and you saw his hand curl into a fist, his breathing falter, his jaw clench like he was fighting something within himself.

And then, when you felt there was no going back, you leaned closer, grazing your lips against his.

Silence.

Just the pounding of your heartbeat in your ears.

He didn’t pull away, but he didn’t move either. And just as you were about to wish the ground would swallow you whole -

Jungkook kissed you.

It was gentle but full of intent. He kissed you like he had been waiting, holding back, and now he couldn’t any longer. He kissed you like he was studying you, tasting you, learning you.

From that day forward, you weren’t just partners in math—you were partners beyond the four walls of the classroom. Partners in exploring each other's bodies, learning each other's sweet spots, tasting each other's skin.

And as days pass you learn a lot about him – like how he’s gentle in the classroom but not in the bedroom. How he spoke softly in school, but rough in bed.

And you couldn’t help but anticipate all the things you could learn from him.

So, when Jungkook offered to teach you Dolbeaut’s Theorem, he didn’t realize the kind of lessons you were truly eager to receive from him.

The moment he sat in his chair and started explaining how Dolbeault's theorem is a complex analog of de Rham's theorem, your mind was on the dripping need between your thighs. So when he told you to focus on the lesson, you dropped to your knees, unzipped his jeans, freeing his already hard cock, your mouth watering at the sight of it.

Your tongue licking along the length of his cock, measuring his girth with your soft, eager lips, wrapping around his swollen tip.

His groans and filthy sounds filled the air as you hollowed your cheeks, taking him deeper. His fingers tangled in your hair, pushing your head down further.

You choked, tears spilling down your cheeks as you took him to the base, your throat tightening around his cock.

“Fuck baby you’re gonna make me cum,” he hissed, voice strained as you licked and sucked, your tongue swirling around the sensitive head. The salty taste of his pre-cum drove you wild, and you feel your cunt clench.

He tastes so sweet so sweet you want more.

And when he couldn’t take it anymore, he grabbed you by the jaw, another hand on your back, as he pushed you to the bed.  

You were about to crawl onto the mattress when he grabbed you by the ankle, flipping you onto your back. In one swift motion, he dragged you to the edge of the bed, spreading your legs wide.

His mouth lapped on your wetness, his tongue flicking over your clit with determined precision. Your back arched as he sucked hard, the nasty wet sounds of his tongue against your pussy filling the room.

“Jungkook!” you cried, your hands fisting in the sheets.

He smirked against you. “So wet for me.”

When he slid two fingers inside you, curling them just right, your vision blurred. He pumped them hard and fast, his lips never leaving your clit.

“You taste so fucking good,” lips glistening as his fingers slammed into you harder, hitting that spot, driving you to the edge of release. But just when you were about to cum, he pulled away, leaving you gasping.

“Fuuuucccck!!! Kook, please!” you gasped, your voice trembling.

And as you writhed in need, hands clawing the sheets, he grinned – or was that a chuckle?

“Hmmm? What’s that baby?”

“Please baby, please…” you begged, whining, as you watched him pump his hard member, tip glistening with pre-cum. He rolled a condom over his length as he watched you squirm. He towered over you as he slapped his cock against your slick entrance, teasing you as he smirked.

“I need words baby girl” he taunted, tapping your swollen clit with the head of his cock.

You just groaned as you stared at his toned abs. Your hips lifted to try and take him in, but he held you down with a firm hand on your stomach.

“Fuck… this pussy” as he pressed just the tip of his cock inside, stretching you torturously slowly.

“Oh god…baby, please. More!” you pleaded, as your breath hitched in need.

“Greedy little whore,” he chuckled, sliding an inch more, slowly.

Oh, you want more. You need more more more -

“You think you can just suck my dick like that?”

You whimper in torment, sobbing, breaking –

He pushed another inch in quick and steady motions, but still not burying all in. And it's driving you crazy, so crazy you claw on his biceps.

“Jungkook! Please!!!”

He chuckled again, staring you down like the beautiful, pathetic mess you were. “You look so pretty like this,” he murmured, his gaze drinking in every inch of you.

Your velvet skin glowed under the light of the computer screen, and your dark hair sprawled messily across his bed.

You grind yourself to him, trying to take more of his hard dick.

“Goddamn baby. You want this dick? You want to take it all?” he growled, pushing in another inch, making you cry out.

Utterly helpless and succumbing to need, you yelled. “Jungkook, please! I need you to fuck me hard baby please!”

He gave a raspy laugh, leaning over you, his eyes dark with a promise. A warning?

“You act like a slut, you’re gonna get fucked like a slut. Do you understand?”

And with both his hands on your jaw, he slammed into you in one brutal thrust, burying himself to the hilt. Your scream echoed in the room as he set a punishing pace, his cock hitting deep, every thrust stealing the breath from your lungs.

“goddamn, so fucking tight” he hissed, one hand now gripping your hips hard enough to leave marks.

You cried his name because words left you, and you can no longer form coherent sentences. You were so drunk on lust, feeling full of his dick – and yet, you still want more. You craved his dick every day and you couldn’t get enough of him.

“Turn over baby. I wanna see your ass” he ordered, flipping you onto your stomach before you could process his words. He yanked your hips up, pressing your face into the mattress as he entered you from behind. His hand fisting your hair, pulling your head back as he leaned down to whisper in your ear.

“You like being used, don’t you? Being my little toy to fuck however I want?”

 “Yes! Fuck!” you sobbed, your body trembling as he pounded into you.

He bit his lip, feeling you clench around his cock, his free hand snaking around to pinch your nipples, then your clit.

“You’re taking me so well.”

Your body tensed, the knot in your stomach tightening, your head blank but seeing stars, and all you can feel was his dick slamming torturously inside you. And as you thought you couldn’t feel fuller, he inserted his thumb into your asshole, his pace never faltering as he stretched you further.

“Fuck!” you cried, your head spinning from the overwhelming sensation.

“You like that?” he chuckled, his voice dripping with pride. “Taking my cock and my thumb like a greedy little slut?”

You could barely respond, drool in your mouth, your moans turning to screams as he fucked you harder, faster, both holes clenching around him as you feel the build to an unbearable peak.

“Speechless now, are we? You like all your holes filled?”

He grabbed the base of your hair, pulling you back to him so you could feel his chest, and hear him whisper filth in your ears. You’re feeling everything, everywhere all at once.

You’re so close, so fucking close –

“You coming baby?”

You could only respond with a nod and noises unknown to man.

“Yeah?”

His thumb pressing deeper, his cock slamming into you relentlessly as he bites the side of your jaw.

“Then come for me”

Your release hit like a tidal wave, your body convulsing as you screamed his name, along with words you couldn’t comprehend.

Fuck fuck fuck.

You come so hard you collapse on the mattress. How Jungkook can make you feel like his nasty little whore, you also don’t know. But you love it.

But just as you thought he was done, Jungkook’s hand slid between your thighs again, his thumb brushing over your abused clit. You jerked, a whimper escaping your lips as the overstimulation sent a jolt through your body.

“Oh, you thought we’re done?” panting, with a smug grin spreading across his face. "We’re not done baby."

“Jungkook, wha—”

And before you knew it, he slammed his hardness back inside you, fingers rubbing your clit until you arch into the sensation. He pressed kisses along your spine, his voice a soothing contradiction to the overwhelming pleasure he was giving you.

“That’s it,” he murmured. “Come for me again baby”

Your body obeyed his commands before your mind could catch up, pulse after pulse, as you ascended to the sky. He slams so hard you feel your eyes roll at the back. You're so close close clo-

“Look at you,” he said, his voice laced with pride. “So fucking perfect. Taking everything I give you.”

Tears pricked your eyes as you felt your thighs trembling. He watched you, his dark eyes devouring every reaction, every twitch and moan.

“Jungkook- im g-gona fucking come”

“I know baby,” he whispered, his lips brushing against your ear. “I know”

And so you come again. Your body shattered under his touch, your orgasm crashing over you in waves so intense that you couldn’t hold back the sobs that broke from your throat. Jungkook didn’t stop, movements quicker now, your walls milking him for all he was worth. He hissed, his thrusts growing erratic before he buried himself deep one last time, his cock twitching as he came hard, filling the condom with a groan.

Fuck.

You left the earth, because there’s no way that wasn’t heaven.

As you both came down from the high, you lay there, spent and trembling. He took his time easing himself out of you. Your spent body still twitching with aftershocks. He laughed lowly, leaning down to brush a soft kiss against your shoulder.

“Let’s get you cleaned up, baby,” he murmured, his voice gentle now, his hands soothing as he helped you sit up.

He disappeared for a moment, returning with a warm, damp cloth. The care he took in cleaning you up was almost as overwhelming as the pleasure he’d just given you.

When he was done, he climbed into bed beside you, pulling you into his arms. You nestled against his chest, inhaling his scent – a mixture of musk, vanilla, and sex.

“I think you did a great job explaining Dolbeaut’s Theorem tonight,” you joked weakly, your voice muffled against his warm skin

Jungkook chuckled. “Uh huh. Guess I’ll have to teach you another lesson tomorrow,” he sighed dramatically, his fingers brushing through your damp hair.

“And what’s that?”

“Equilateral triangle.”

“…because I have three equal sides?”

“Because you’ve got all the right proportions.”

You rolled your eyes. “Baby, sometimes you’ve gotta know where to draw the line.”

Before he could say another punny joke about lines, you kissed his smile and swallowed his laugh.

And once again, you feel the soreness in your core—a reminder of your just-concluded learning session today.

An entire hour and he only looked at you once, if that’s what you could even call it. His cat shaped eyes, glanced over you, as if judging your appearance before we went back to looking down at the table with his arms crossed over his chest. Almost like he was annoyed or something. He was hard to read, so you couldn’t really tell if he was actually listening or if he just got annoyed because of your presence. Either way, it was rude as fuck. Just because he was part of the biggest boy group, he didn’t have the right to treat you this way. 

Min Yoongi, Suga of BTS, was now your husband but he wasn’t putting in any effort so far and you two had been in this room for quite some time. You stayed quiet, only nodding your head when spoken to, which he didn’t see because he was too busy looking over the paperwork, like he was avoiding your very existence. After signing the few documents, you stood up, adjusting your black corduroy skirt and black turtleneck sweater and grabbed your folder before heading out of the room with the others that were present in the room with the both of you. After speaking with your lawyer privately, you waited by the elevator, tapping away at your phone with light pink manicured fingernails. 

Being the owner of a record store wasn’t exactly the best decision you made but it did bring in money. Some people still used record players and even most of the young generation. You had always loved music, especially old music. A record store was always a dream of yours and although you struggled in the beginning, it was all worth it in the end. It was actually Manager Sejin that came to you with the arranged marriage offer. He was a good customer of yours, loved your store and saw how hard you worked everyday and rambled about your love for your passion. You didn’t care about fame, but you did care about at least meeting someone, especially in South Korea. 

You weren’t the skinniest girl, that was for sure. You had an hourglass shape but by no means were you on the thin side, which was probably why it was hard for you to date. You lived in Korea for 5 years, always bought clothes online since most stores didn’t fit you and because of your african american background, you always did your own hair. Right now your hair was straight, medium brown with dark roots. You only had it that way because of the winter and it would last. You weren’t too heavy, a little gut that you were working on but your overall appearance seemed intimidating to most men. If you weren’t small enough for them, you either became a friend or they just never spoke to you again after having a one night stand.

Your bust was slightly bigger than average and your hips weren’t too wide but wide enough. Your medium to light brown skin always had a glow to it though, nothing bothered you and every time someone gave you a disapproving look, you would pretend that you wouldn’t see it. 

Standing by the elevator, you could see Yoongi walking out of the corner of your eye, in the opposite direction of you. Raising a brow, you noticed Manager Seijin approaching with a smile. “He still has some work he wants to work on in the studio if you’re okay with that, he’ll meet you at the apartment later on tonight. He insisted he go back so..” He shrugged and you smiled with a nod. “No problem. Thank you.” You bowed and made your way down the elevator and out to the car that was to drop you off. 

It wasn’t really an apartment but more like a townhome, gated but still in its own little town. You figured the other wives were living here as well and wondered how they were adjusting. Friends weren’t always a thing with you, they came and went but you wondered if the other women would become your permanent friends. All of you were in this arranged marriage anyways. 

Yoongi definitely wasn’t going to ruin your mood for the rest of the day so you keep yourself occupied, setting up your record player in the bedroom and putting on something upbeat so you could dance around while putting your things away. You cleaned as you went, and even lit a few candles so it would smell less like a new apartment and more like a home. He probably was busy and just didn’t have time for you to introduce yourself, it was understandable. 

Once your things were put away, you showered, wrapped up your hair and changed into a comfy two piece pajama pant set, black and yellow shorts, a tank top and long robe to match. You cooked bulgogi and even made enough for Yoongi as well. Placing his in a container and set it on the counter, you figured he’d warm it up when he got home. You ate your portion, alone, and cleaned up before sitting on the couch to watch some t.v while making sure that your new employee closed up the store properly. 

It had almost been 8 hours since the meeting and it was getting dark, and there was still no Yoongi, you sighed heavily, walking over to the window and peeking out. No sign of a car or him walking around. You know you didn’t do anything wrong, yet you felt like you did. Maybe you should have spoken up and said something to him. Maybe you weren’t his type. Rolling your eyes, you shook those thoughts away and walked upstairs and into the bedroom after blowing out the candles you lit earlier. 

The bed was huge, bigger than the one you had previously owned when you lived right above your record store. Everything there was in one room so having the extra space was nice. You remembered you had to exchange numbers with Yoongi so you sent him a quick text, in English, asking if he was coming home. It showed that it was delivered but not read. Tossing your phone on the nightstand, you turned over and quickly drifted off to sleep. 

-----------------------------------------------------------------------------------------------------------

You woke up rather early the next morning, glancing at your phone that read 7:45 am, and with no returned text messages or phone calls. You saw that the text was still unread and you rolled over to seeing nobody there. Sitting up, you noticed the bathroom door was opened so he had to be here. 

Standing up from the bed, you put on your robe and made your way down the stairs and into the living room, seeing Yoongi’s golden locks peeking from under a blanket on the couch. WAS HE FOR REAL?! He slept on the couch, to avoid sleeping in the bed. Maybe he didn’t want to wake you? It had to be that. He probably got back late and didn’t want to disturb your sleep. Going back upstairs to get ready for the day, you dressed in an oversized black sweater, denim blue jeans and kept your black socks on while doing your makeup, something simple and brushing out your hair. 

Walking back down the stairs with a jacket in your hand, you saw him sitting up, his back facing you while he rubbed his eyes and yawned. “Good morning.” You spoke in English, knowing that he knew but all he did was look at you over his shoulder, turn back around and stood up to fold the blanket he was using.

Rude. Rude as hell. Tossing your jacket on the back of the couch, you walked into the kitchen, seeing that the container was empty and in the sink. Well, at least he ate. You thought while cleaning it out and placing it on the drying rack. “I said, good morning. Yoongi.” You said his name this time and he deeply sighed before looking at you again while walking past you and up the stairs. 

An hour later when he came down, fully dressed with one air pod in his ear, talking on the phone in a conference call with the boys. “She doesn’t even know Korean. She made food last night, it was pretty good though, but I’m not teaching her Korean just because we’re married...Taehyung you like your wife and so does Hobi...I don’t have to like her...no she’s not ugly but that’s besides the point. They found me some Koreaboo that probably only likes me because of BTS. This is a set up…” He rambled while you cooked, almost burning the eggs after hearing what he was saying. He didn’t know you knew Korean which meant he wasn’t listening in the first place and a Koreaboo? How insulting. 

Humming to yourself, you finished the omelets and side of toast and poured both of you cups of coffee. “Breakfast.” You said slowly to him, smiling. He rolled his eyes and hung up with the guys after telling them that you think he didn’t know much English. He sat down, eating slowly and sipping his coffee. You leaned back in your seat, watching him and shook your head while giggling. His eyes darted up at you and he tilted his head to the side in confusion. 

You cleared your throat, finishing your food and waited for him to finish his, cleaning the dishes once again and went over to grab your jacket. “I think we should go grocery shopping, I only bought enough for the Bulgogi last night. I’m glad you thought it was good, maybe I can try other dishes that you like and don’t worry about teaching me Korean. Clearly I already know it. Ready to go?” You said all of this while putting on your shoes and zipping up your coat, turning to face him.

The full clothes stand which partially blocked the entrance to the living room caught his attention as soon as he closed the front door, its sides overflowing with damp laundry. He wondered why it was in the hall, before noticing the portable heater which had been placed precariously close to a dangling sleeve. Its presence made his heart skip unexpectedly, realising it meant Ara was home. The lack of noise from the adjoining sitting room told him she was likely in the bedroom and the urge to go straight to her was overwhelming, but he took the time to switch off the electrical device, sensing she had forgotten about it and not wanting to risk a fire. As he straightened, his eyes were drawn to a pink garment folded over the edge of the rack; the tiny logo embroidered on the pocket instantly recognisable. His mouth dropped open in a silent gasp and dropping his shoulder bag on the floor, he unhooked the material, heading down the hall. 

“Ara?” Twisting the door knob and pushing into the bedroom, he called out her name, eyes fixed on the long-sleeved shirt which he held at arm’s length, as though the bundle of fabric were covered in bugs. “What happened?” He asked.

She looked up from the duvet where she was laying outstretched on her side, a hard-backed book resting on the pillow in front of her. “Oh.” Noticing his entrance, she sat up at once, curling her bare legs to prop up her slender body.

Jimin looked from the shirt to his girlfriend who blushed in response, raising her hands from her covered lap to her face. “I’m sorry…” She cringed, placing her palms flat on her eyes for a moment before removing them with a grimace. “I saw the laundry basket was full and wanted to be helpful.”

“It’s my favourite shirt!” He exclaimed with exasperation as he drew it to his body and turned the garment over in his hands. Its once pristinely white colour was now stained to a rose-hued blush. 

“I know…I really am sorry.” She groaned. “I thought it was all your clothes, but there was something red in the basket.” 

Her cheeks remained pink as she shifted position on the bed, adjusting the trim of her low-cut dress to protect her modesty as she looked at him. While the ruined shirt had been a shock, he could see she had meant well by washing the clothes which he had so carelessly left strung around the apartment in her absence, and couldn’t be angry with her. He took a deep breath.

“What was it?” He asked with curiosity, voice softening as he discarded the shirt on the edge of the duvet and crawled to sit beside her.

She hesitated for a moment, before shaking her head. “You don’t want to know.”

A sly grin crept onto his face. “Now I do…”

Her hands once more rose to her face, clutching her cheeks in embarrassment. “It was one of my thongs.” She admitted quietly, prompting Jimin to grin widely, his eyes wrinkling at the corners as he stroked her bare knee gently. 

“Well, I guess they’re pretty tiny…” He teased.

“Shut up.” A matching smile grew on her face as she placed her hand on top of his. It was obvious she was feeling bashful about the whole situation as well as a little deflated, having admitted to him on a number of occasions that she sometimes found it hard to complete daily chores around the house, often becoming distracted or accidentally breaking something. Once, while sweeping up the large shards of a shattered glass on her hands and knees in the kitchen she had broke down in tears and, through the sobs, declared to him that she was failing as an adult. 

Jimin let it drop and, leaning forward, kissed her cheek gently. He could feel its heat radiating from the surface of her soft skin. “What time did you get back?”

She seemed to glow in the aftermath of his touch, her digits slowly wrapping around his as she recovered from her embarrassment. “In the afternoon. Didn’t you get my text?” She frowned.

“Not yet.” He said, having last checked his phone just before the short drive home.

“Oh.” Ara murmured. “I sent it before I set off. Maybe it’s stuck in the...whatdoyoucallit?”

“Ethos?” He suggested.

She let out a laugh, her fingers stroking his as she shook her head. “Ether.” She corrected.

His mouth twisted in a smirk at his simple mistake. “I’m not sure texts can get stuck in the ether.” He shrugged. “It’s not got a net.”

Playfully, she gently hit his upper arm. “You know what I mean.” A giggle escaped her lips. “Maybe it’s delayed because of the phone services abroad.”

He internally groaned. “You should have waited until you got back. It will cost you a fortune.”

She met his gaze, eyes sparkling. “We’re going to debut next month, so I’m hoping I’ll see a proper paycheck soon.”

“I wouldn’t hold your breath.” He sighed discouragingly. “It took us years to make any money.” 

“I’m sure I can at least pay off my phone bill…” She reasoned gently before a hushed, but comfortable silence fell between them. They naturally moved down the bed, huddling closely together as they shuffled against the duvet to get comfortable on their sides. His arm glided across her waist, feeling the gentle curve of her hips beneath her dress as they faced each other.

It took a moment to register what she had said, and a timid smile crept onto his lips. “So you’re going to debut?”

She nodded. The change in position felt more personal; more loving, and she lowered her voice to a more intimate tone. “In Japan. They think we’ll be more of a hit over there.”

“You’ll be a hit everywhere.” He flirted, fingertips leaving her hip to roam under the floaty trim of her clothes. “Especially if you wear this dress…”

She slapped his hand with a toothy grin and he pulled away quickly. “Stop playing!” 

With a laugh, he resumed his previous position, holding her waist steady. “Do you like being in Japan?” He murmured. 

She hesitated. “Sort of…I miss home though.” 

He heard the longing in her tone along with something else; something which sounded like regret. “What do you miss the most?” He inquired softly, shuffling closer until he could feel her warm breath against his face.

“The smell of my bedsheets when I’m with you.”

“Mmm.” He mumbled in agreement, letting out the softest moan as he pecked her lips. Her sweet, fruity fragrance seemed to linger in the air, even when she wasn’t there and in the days following her marketing trip, he had hugged the duvet at night, pretending she was with him. “Anything else?” He said hopefully. 

“Homemade kimchi.” 

Her blunt answer made him laugh out loud, and he reluctantly pulled away to prop himself against the headboard, suddenly remembering he had interrupted something when he barged into the room. He glanced at the edge of the quilt as she joined him, her movements a little groggy from her long day at the airport. 

“What are you reading?” He asked, squinting to see the cover which was wedged open on the sheets.

“Poetry.” She followed his gaze and picked up the book, placing it carefully on the bedside table. 

“You like poetry?” He toyed, eyes full of mirth. 

Shrugging, she turned back to him. “I’m trying to write some lyrics. I thought I might get inspired.”

His eyebrow raised teasingly. “So you’re a song writer now?”

“I don’t see why not.” Her voice was a little musical as she resumed her previous volume. “It’s not like I’m ever going to be the lead dancer.”

“I thought you were getting better?” He frowned, sensing the complaint in her tone. 

“I was…” Drifting off, she thought for a moment with furrowed brows. “It’s just more difficult with dyspraxia...I get all flustered and lose my balance…” She explained dejectedly. “I’m taking the lead vocals instead.”

This perked him up. “Are you serious?”

Nodding, she observed his smile and sighed. “I feel bad for the others. They’ve been working so much longer than me. It doesn’t seem fair I get to fasttrack…” The falter in her voice made him realise this had been playing on her mind for a while. 

“I wouldn’t complain…” He said softly, stroking her hand. “You’ll work hard enough in the end, trust me.”

She shrugged. “I guess so…”

Her eyes followed his movement as his hand found hers, a minute of silence stretching between them before he interrupted her thoughts. 

“So the thong that ruined my shirt…” His expression was unreadable as he turned to her. 

“Yeah?” She questioned timidly. 

“Are you wearing it now?” He gently mocked, lifting the hem of her pretty dress before she could protest and taking a peak at the little, frilly triangle of material between her thighs. They were a pale yellow, not red, but he grinned regardless as she tugged the fabric from his grasp and yanked it down.

“Stop!” She squealed, unable to help her giggles as he pulled away with a grumble. “You should get something to eat…” She insisted, calming down and gesturing towards the door. It was getting late and, as predicted, he hadn’t eaten since midday. 

“Okay…okay...I’m going…” He sighed dramatically as he slowly rolled off the bed and got to his feet. “I’ll make you some kimchi. Will that make you happy?” He turned back to look as she picked up her book, finding her place among the aged and slightly bent pages. 

Her lips turned up as she drew her gaze from the hardback. “The happiest.”
