You'd barely even gotten through the front door to his apartment before he was in front of you. He greeted you with the usual kiss and hug, but there was an obvious excitement inside of him, waiting to be let out. You noticed it immediately, like there was a spurt of creativity he was holding in.
You set your bag down and plopped down on the couch, tired after work, whereas Hyunjin grabbed your foot and started massaging it attentively, a toothy smile on his face. It was clear he was thinking about something. You tilted your head at him.
"What have you been doing today? You seem... happy about something," you said, putting it out there for him to express his thoughts without directly asking. He looked up from his focus on your foot with a calmer smile, his nimble fingers still kneading your soft skin.
"Mm, not much. You know I had that shoot earlier - that went well. Chan wanted me to do some recordings in the studio, so I did that, too. How about you, baby?" he responded casually, listing off all the things he'd done today more or less.
You nodded, letting out a small, pleased hum at the feeling of him massaging your foot. "Work, mostly. It was a bit tiring, but I managed with enough coffee in my system." You let out a chuckle, adjusting yourself against the couch to lay down more comfortably. Hyunjin took this as his chance to switch over to massage your other foot.
He nodded, still smiling calmly to himself like he was thinking about something. You squinted your eyes at him. Your curiosity could only be held back for so long.
"Okay, what's with that giddy smile on your face? What are you thinking about?" you asked, pressing your foot against his hand a little to gain his attention.
He shrugged, like he was trying to brush it off. "Nothing."
You wouldn't have that. "Tell me," you whined.
"It's nothing. Just this movie I watched. It was... inspiring."
"Well, what was it about?"
That made him pause his ministrations on your foot for a moment, biting his lip as he tried to hold back a smile, holding back his excitement even now. He shot you a look, smiling that almost sheepish smile that showed off his front teeth. It made you smile too, chuckling a bit at his reaction.
"Come on, tell me!"
He sat up then, releasing your foot and began to ramble on. "It was this movie about a secretary, and the man she worked for began treating her... well, as a secretary. But whenever she would do something incorrect, he'd make sure to punish her. And she loved it, explored herself in that way. They were both matching each other so well, and it kind of reminded me of us. And just the whole aesthetic of the movie was pleasing to the eye. It made me excited to try something new."
You tilted your head intuitively as you listened to him explain the movie, slowly catching onto what sort of movie it was. How was it that Hyunjin could make something that was supposedly a kinky movie into something that sounded romantic?
Once you'd thought it over, you found it in you to respond to him, slightly teasing, "So what you're telling me is that you watched some kinky movie and thought of us? That's cute." You laughed a little at his enthusiasm about this movie, but you also wanted it to be known that you were listening. After all, you did find it a little flattering that he was this giddy over the thought of doing something with you. "...So what did you have in mind? Since you want to try something new."
It made your face a little hot to ask, but Hyunjin was just excited to talk about it. "One day, I'd like us to roleplay. You're a student and I'm your teacher. I want you to wear an outfit and everything - so will I."
You were a little taken aback, only because Hyunjin had never brought up an interest in roleplay before, but to you the idea was definitely appealing. Still, you let out a small laugh, feeling a little shy when you thought of it for too long, slowly nodding. "Alright..."
Hyunjin smiled, seemingly not feeling shy at all about the topic. He leaned over and kissed your cheek, tangling his fingers with yours as he started talking about something entirely different.
─────────────────
It had been more than a week since you'd talked about Hyunjin's new fantasy. He hadn't even hinted at it, even though you'd been intimate since then. After a few days, you'd forgotten about it, too focused on life to consider when it might happen.
But then, when Hyunjin came to your place from what you thought had just been dance practice, he plopped a package onto the table. You looked up from your book, raising an eyebrow at him and eyeing the package suspiciously. "What's this?"
He smiled, taking off his sunglasses he'd been wearing and began opening the package. "It's for you."
Your ears perked up a the sound of that, setting your book aside and excitedly making your way towards him. You kissed his cheek in a silent greeting before tearing into the package. Meanwhile, Hyunjin placed his duffel bag on the table and began to look through it, glancing over at you while you opened the package.
Your lips parted in surprise when the contents of it revealed itself and you found yourself holding up a plaid mini skirt, a white, revealing dress shirt, knee-high socks and a matching hairband. You looked the clothing over for a second before turning to Hyunjin, raising an eyebrow.
He was already holding an outfit for himself that he'd packed in the duffel bag, a dark suit and striped tie, a pair of glasses on the table. Finally he seemed to be feeling a little flustered, shuffling on his feet. "I thought we could try the roleplaying thing today... bought us some outfits," he mumbled, almost nervously. Like you might reject the idea now.
His sudden nerves only brought an adoring smile on your face, your fingers holding onto the clothes a little tighter. You nodded. "You want me to change into it now?"
He nodded, his eyes big and clearly trying to hold back the excitement that was hidden under his shyness. You brushed your thumb across his cheek with affection at his expression, finding it cute, before turning on your heels to go change in your bedroom.
Hyunjin cleared his throat, calling out behind you. "Sit by your desk once you've changed. I'll bring in your assignment for correction."
You stilled by the doorway to your bedroom, looking at him over your shoulder when those words left him. It was surprising to hear from him, already sort of getting into character. It sent an excited thrill through you. You nodded once, shutting the door behind you as you walked into your room.
As you got undressed, you could feel your nerves heightening more and more, the anticipation of what was about to happen leaving your stomach in knots. It made you more excited than you'd been in a while.
You decided to keep your underwear on beneath the clothing, since he'd made no comment on what to do with that .There hadn't been any included in the outfit he gave you. You looked yourself in the mirror, taking in the way you looked. You definitely wouldn't have been allowed to wear this at an actual school - skirt so short that your ass was peeking out, cleavage on display... clearly Hyunjin had thought this out.
"Okay..." you whispered to yourself, running a hand through your hair, careful of the headband, before taking a seat by your desk. You weren't sure why you felt so nervous. Maybe it was just the anticipation of it all, or the thought of Hyunjin dressed up in a suit and tie, ready to correct you.
You ran a hand over the skirt, feeling a little skittish, but paused when you heard the sound of the door opening. Your heart lurched to your throat, hands falling to your lap when you heard the sound of leather shoes against the floorboard. The urge to turn around got the best of you, glancing him over your shoulder.
He looked immaculate. His sleek pants were just a little loose, white dress shirt revealing some of his chest under the blazer he wore. And then the tie and glasses - God, did he look good. The tie was loose, adding to his usual characteristics. If he liked the looks of you, too, he didn't make it clear on his face, though he could definitely feel his pants getting a little tighter.
In his hand was a pen and paper, but they were the last thing you were looking at. He raised an eyebrow at you, clearing his throat and adjusting his tie, painfully aware of how you looked at him. His nerves were tickling his skin, but he wanted so badly not to seem awkward. That wasn't what this was about. He slowly made his way towards you, sliding the paper in front of you.
"Miss y/n," he started in greeting, keeping his voice firm. "You're a good student. You aways show up on time, answer in class when I call on you, get good grades - you know how to work hard." He stood behind you now, leaning over you so you could feel the heat of him against your back. He tapped the paper twice with the pen, expecting your gaze to follow. "So explain to me how such a progressive student finds it acceptable to hand in something so mediocre."
You sat there for a moment, just thinking to yourself this is really happening, this is really happening, your eyes locked on how the veins popped out of his hand where he held the pen. Then your eyes drifted to the paper, to a text you hadn't read before, some letters or words circled in red. You weren't sure what to say, still trying to ease into the whole roleplay antic of it all.
"...I'm sorry, Mr. Hwang. I did my best-"
"-You can't even spell basic words right." He interrupted you, still stood behind you, his presence all-consuming.
You swallowed thickly, teeth digging into your bottom lip. His words shouldn't have brought as much heat through your body as they did. You could get used to hearing such authority in his voice.
He leaned over you even more then, placing both hands on the table with his palms pressing against the surface, caging you in from behind.
"It's unacceptable."
You could feel his breath fanning the back of your head, your body tensing up and breathing getting heavier, excitement causing through every part of your being.
"Mr. Hwang-"
"-You will address me as Sir."
You fisted your hands in your skirt, your thighs pressing together as you loosened the smallest of breaths. Maybe you wouldn't even make it to the main event before you lost your mind.
"Get up," he said then, stepping far enough away from you that you couldn't feel his heat anymore. The lack of warmth was slightly disappointing, but the unknown of what he had planned got you over the loss fast.
You stood, ass surely on display from that action alone, your hand shaking a little when you placed it on the chair for support. You met his eyes then, and you had to stop every fibre of your being from not just jumping him right then and there. You were aware of his eyes on you, how they took you in, and even then the tent in his pants made it obvious how much he enjoyed this, too.
"Bend over the desk."
He moved the chair out of the way, giving you room to follow through with his command. And though you did as he said, your movements were slow, making sure to feel remember every moment of this experience. You placed your hands on the table, on either side of the paper, bending over it enough to expose your entire backside to him. You heard the small release of a breath through his nose, felt his eyes on you the whole time.
"Now read the paper. Out loud," came his next command, something you hadn't exactly expected him to say. You knew it was all part of the roleplay, but you had no idea what the paper would even say. From the looks of it, it was just some random excerpt from a text.
"The importance of avoiding smoking," you started with the title of the page, your ears sharp as you heard him shift behind you, only building up the anticipation. You cleared your throat and continued, "Smoking is one of the leading causes of preventable health worldwide. It can increase the risk of serious diseases such as lung cancer, heart disease and res-"
You paused your reading when his hand came down on your ass hard, instead letting out a choked sound at the sudden sting. Your hands pressed harder against the desk, slightly shaky as you loosened a breath. You turned your head to glance at him over your shoulder, but he stood at an angle where you couldn't see his beautiful face.
"Keep reading," was all he said, the tone of his voice lower. He waited for you to continue, expected you to. You had to stop yourself from pressing your thighs together again.
You looked down at the paper, trying to focus on the text, on where you'd left off instead of when the next hit was going to come. "-and respiratory illness. In addition to affecting the smoker-" you read over a couple of words or letters that had been circled, spelled wrong, correcting them as you read out loud, "-secondhand smoke can also harm people nearby-" another smack landed on your ass, then another, halting your reading for a moment.
"Don't stop," he ordered.
"-Including children-" smack! "-a-and non-smokers. Choosing not to smoke can-" smack! "c-can lead to improved physical health, better lung function, and-" smack! "a-and increased energy levels..."
You trailed off, shutting your eyes and breathing out. He was not going easy on you, that was for sure, your ass already stinging, skin raw and only getting redder. There was only a little bit of the text left, but you doubted it would end there.
In one swift movement, he gathered your hair into his hand, yanking it back enough to strain your neck and sting your scalp. "I. Said. Read." He let go of your hair, using the same hand to land numerous sharp spanks against your already sore backside, not stopping until you started reading again.
A broken whimper escaped you before you spoke again, "It can also reduce healthcare costs and improve-" smack! "overall qual-" smack! "q-quality of l-life-" smack! smack! smack!
His hand came cracking down mercilessly, and your legs wobbled beneath you, a pained mewl escaping you. Your nails dug into the wood of the desk, your eyes stinging but your sopping cunt throbbing for more.
He let out an impatient sigh when you stopped reading again, clearly affected by the harsh delivery of each hit. He stopped for a moment, pulling something out from his pants pocket before pressing down on your lower back.
"Start over," he said, to the masochist inside you's great pleasure, but your greedy cunt's distaste. You lowered your head again, your arms already tiring, starting from the beginning of the page again.
You felt a graze of something cold, metallic on your sore behind, causing you to twitch. His hand on your lower back kept you in place, and you wisely continued to read as he raised his hand.
Down came the surface of the cool ruler on your ass, achieving a more sharp and clean hit, but also more painful and punishing. It took everything in you to not just stop reading altogether, instead keeping your focus and continuing to read once the sting of every hit blended in with the rest.
He continued using the ruler, until the once cool metal of it turned warm from the contact with your skin, your ass numb and sensitive, burning hot. Somehow you made it through to the end of the page, tears streaking your cheeks and arousal soaking your panties. He let out a breath from the exertion of abusing your poor behind, setting the ruler down on the desk next to your hand.
"Good. That was good. You have some mind left in there, after all," Hyunjin muttered, his hand brushing over your bruising skin. You whimpered at the pain you felt, though there was something soothing about his gentle massaging of your skin, even if it made you cry more. "Can you say 'thank you', baby? My hand is a little sore after having to correct you. That's your fault, isn't it?"
Hyunjin was clearly into the roleplay thing completely now, you would've even considered giving him an Oscar for his performance. But so were you, forced into it, anyway, with how he'd just smacked the life out of your ass. You sniffled and his cock hardened at the sound. "Th-thank you, Sir."
He hummed, pleased by the sound of you thanking him for his cruelty. He stroked himself over his pants, finding it hard to control himself when you called him by such a title. He'd never heard you say it before but it had almost just made him cum in his pants, despite the composure he held in front of you.
"That's right. You're a good pup, aren't you?"
You nodded vigorously, eager for the praise. His hand moved down to where you were soaking through your panties, arousal coating the lacy material and your inner thighs from having your legs pressed together. You whimpered at the feeling, sensitive but your cunt oh so greedy for more. He let out a groan once discovering the effect he'd had on you. "Oh, puppy, look at you. You liked that, didn't you? Fuck, you're so sick..."
You whimpered at those otherwise offensive words, but when he said it they sounded so right, like he wouldn't have it any other way. And he wouldn't - he was as sick as you, maybe even more so for doing this to you in the first place.
He used his long fingers to push your panties to the side, running them through your slick, feeling how filthy you were. He groaned again, giving you a little reward by curling two of his fingers inside of you, feeling how your walls clenched around them, hungry for more.
"Fuck... Why'd you even bother wearing these anyway, hm? We both know your indecency wouldn't make you any less of a slut."
You moaned, legs leaning against the desk now, trying to keep yourself upright instead of just collapsing to the ground like your body desired. The small relief of his fingers pushing into you after not having been touched brought you a greater pleasure than it usually would've, your hips grinding against them with need.
"S-sir, please- please-" you moaned in desperation, craning your neck as you squeezed your eyes shut. He let you grind against his fingers, too busy watching you unravel at his touch to think of punishing you for doing so. The sound of your begging was just so beautiful.
"Please what, pretty? Come on, you can say it," he muttered, distracted by the beauty of you to make his words any sort of firm. His clothed bulge pressed against your sore ass, the imprint clear through his pants. You whimpered, grinding against him.
"P-please- please fuck me- please, I need it so bad- please, Sir!"
Hyunjin had to stop himself for cumming already once more, his fingers trembling as they exited your sopping cunt. He spun you around, finally letting you face him, enabling you to see the darkness of his eyes behind his glasses and him the tearful look on your face. Just how he liked it.
"Alright, my love."
He leaned in and pressed his lips to yours, the soft plumpness of them bringing you a sort of calm. You'd been unaware of how much you'd needed his affection after such a roughhousing, and now that you had it you felt reenergised.
He hummed into your mouth, parting his lips against yours in a slow, but hungry kiss. Even after all that had gone down, he couldn't help but bring the usual soft, hopeless romantic in him out; it was just in his nature.
His hand came up to loosen his tie even more as his tongue rolled languidly over yours, sucking gently on the vessel. Your hands moved to his chest, feeling him over the blazer. He'd even put on some sort of cologne, the scent clinging to the suit, and it filled your nostrils with its pleasant smell. It only made him all the more sexy.
He pulled away to tug the tie off of his head, his lips red and swollen from the kiss, making him all the more hypnotising to look at. He took the tie and put it over your head, wrapping the material around your neck and began to tighten it. The light restriction around your throat made you moan, eyes intensely looking into his to let him know just how much you enjoyed the friction.
He let out a growl, lips twitching at the corners of his mouth, tightening the tie a little more before tugging on the end of it. Your head moved closer to his then, the action sending a shiver down your spine and heat rushing to your core.
You glanced a look at his hard cock where it was begging for release beneath his pants, before his lips were on yours again, a little more desperate and no less hungry. You kissed him back with as much fervour, matching his pace, before lifting your leg up and letting your foot rub the outline of his cock over the smooth clothing.
He groaned loudly at the sudden contact, breaking away from your lips to look down at your foot rubbing over him, the image before him so lewd he could hardly take his eyes off of it. But he managed to gather himself, glaring at you while you blinked innocently, even with your foot over his cock. He grabbed you by the ankle.
He shook his head. "Bad. Bad pup."
He let your leg fall down before tugging on the tie hard enough to pull you forward and make your breath catch in your throat, his teeth finding your neck and biting down hard. You mewled, your hips grinding against his thigh in desperation, the mix of pain and pleasure driving you wild.
"Please..! Please I can't take it anymore-!" You whined, hands trembling as you clung to his blazer, longing for contact.
Even through his own desperation to feel your warmth wrapped around him he chuckled at your neediness, finding your whining adorable.
He let go of the tie for a moment to lift you onto the desk, his heart clenching slightly when you hissed at the soreness of your ass pressing against the wood. But he'd tend to that later. He pushed your skirt up and pulled down your panties all the way, shoving them into the pocket of his pants.
In one swift motion he had said pants pushed down to his ankles, revealing how he hadn't been wearing anything underneath this entire time. His admirable length stood tall and lean just like the rest of him, ready to be buried inside of your cunt. He stroked himself, pulling you towards the edge of the desk, towards him, crashing his lips to yours again. His desperation made it hard to remember to stay in character.
"Fuck, baby- I can't wait to feel you wrapped around me- God, you're so wet," he practically whimpered against your lips as he rubbed his length through your slick, wetting himself in you.
You couldn't stop yourself from looking down at the sight of it, watching as he slowly pushed into you with a groan. You moaned, finally feeling full as he pushed all the way in, your arms wrapping around his neck to support yourself. His hands trembled, wrapping his arms around you in a loving embrace before beginning to move his hips.
He moved with ease, sliding in and out of your soaked cunt like you were made for him, walls shaped to fit around him. He grunted with each thrust, his tip hitting the back of you due to the angle he had you in. Your eyes rolled to the back of your head at the feeling, your head tilting back, body moving out of your control. You'd already cum just from this.
Hyunjin gathered enough senses to move his face away from where he'd buried it against your neck, hair falling in front of the glasses he wore, watching you fall apart.
"Ah- I can feel you squeezing me, baby. Ngh- cum for me, pretty. Cum for me..!"
His hand moved down, thumb rolling over your clit to bring you over the edge, and he was left in astonishment as pleasure washed over you, your body twitching under his. His lips parted in awe watching your body fall apart, seeing how your face scrunched up and hearing those sweet sounds leave your lips.
Your walls squeezing him tightly made it harder to hold back, but he managed, wrapping the tie around his hand to bring you closer to him again as he kept fucking into you, jaw clenched tight. You could barely open your eyes at first, but the strain against your throat forced you to focus on the present.
Your eyes met his again, taking in the sight of sweat beading down his face, his lips red and parted so beautifully you wished you could eat up every part of him. Just then you gained enough energy back to reach up, wrapping your hand around his throat as much as you were capable of doing, restricting his breathing just slightly.
He let out an almost pained whimper, unable to hold back the sound, hips stuttering. He glared at you even when pleasure threatened to make him spill inside of you, his hand leaving the tie to smack you across the face before tugging you close again.
"You little devil," he grunted, his hot breath fanning your face before he kissed you again, your moans mixing together. You could only manage a small smile against his lips before you were overwhelmed with pleasure again, feeling your second orgasm closing in as he kept fucking you against the desk.
You were both reduced to stuttering moans and heated, sloppy kisses, your highs closing in, bodies moving in sync like a perfect symphony.
"C-cum with me, Hyunjin..!" you choked out, your fingers tugging at the ends of his hair, knowing it would bring him closer. And it did. With a high-pitched moan his hips stuttered, the hot spurts of his cum filling you up as he came. You rubbed your middle finger over your clit desperately while watching him cum, the sight pushing you over the edge for a second time as you arched up against him.
The room was reduced to the sound of your heavy breathing, your sweaty bodies clinging to each other as you both came down from your intense highs.
Eventually you felt Hyunjin move, his hand coming up to stroke the back of your head, lips pressing against your hair. You hummed in pleasure, not wanting to move just yet. You could finally feel the overexertion on your body, the soreness that settled over your limbs.
He pulled back after a moment, taking in the ruined state of you. He looked like he might be amused at the sight, but a mild concern was clear on his face. "You okay? I wasn't... I wasn't too rough, right? You liked it?"
He wanted to make sure you had enjoyed the experience. That you had liked it as much as he had, because he most certainly had liked it. You shook your head and gave him a soft smile in reassurance, leaning into his touch when he brushed his thumb over your cheek affectionately.
"No, I definitely liked it," you said, nudging your nose against his. You couldn't help feeling a little clingy after such a rough session.
He let himself smile then, nodding his head and removing the glasses on his face to rub some of the sweat away. "Good... So we can do it again?"
The look on his face was almost comical, just as excited as he'd been when he had mentioned the idea of roleplaying in the first place. You laughed, resting your head against his shoulder.
"Yeah, we can do it again... although maybe not right now. I don't think I can even stand right now."
He looked down at you then, remembering the abuse he'd caused on your ass, and various other places... Well, he felt a little proud of himself. But he knew to care for you, too.
"Right... Come here."
He pulled out of you slowly before helping you stand, assessing the damage on your backside. He grimaced slightly, the skin already starting to bruise. But he didn't mention that just yet, instead loosening the tie around your throat and pulling it over your head. He almost aww-ed at the tired look on your face, kissing your forehead.
"Let's get you cleaned up."
