chapter 1 chapter 2 chapter 3
The next week passed in a haze. You couldn't stop thinking about Namjoon leaning over you at your desk, how calmly dominating he had been as he slipped his thumb into your mouth, how the smell of his cologne had lingered as you sat frozen at your desk once he’d finally shut the door behind him. It made you shiver to remember his eyes locking with yours, and the mixture of fear and pleasure that had rushed through you. Because no matter what you told yourself, you were a little afraid of him. He had seen straight through you in a way nobody else had in a very long time.
It was 9 o’clock the following Friday when you were sitting at the desk in your office checking over your schedule for the day, the same way you always did, and scanned the list of tutorials students had booked for the afternoon. Your mouth went dry as you saw the last name on the list - Kim Namjoon. Had he booked that slot on purpose? He must have done, he must have wanted to wait for you to be finished with everything else and for there to be no need to rush. Or was it just that the last slot was most convenient for him? Somehow you didn’t think that was the case. You took a deep breath and closed your eyes for a moment, trying to ignore the sudden increase in your heart rate. You couldn’t push away the image of him standing over you, tall and imposing, daring to cross the unspoken line of student and academic even though you’d guess he was a couple of years older than you. It couldn’t happen again, could it? What would you do if he did? Would you push him away from you or pull him closer?
The afternoon’s appointments rushed past, and more than once you caught yourself losing the thread of conversation with your other students. You couldn’t help feeling guilty and a little ashamed of how excited you were to see Namjoon, even though you knew the anticipation you were feeling was illicit. But maybe you had worn your favourite dress on purpose, maybe you had done your makeup a little more carefully than usual, maybe you had applied your lip balm more often that day because you knew you’d be seeing him, but you’d never admit that even to yourself.
‘Professor?’ he called softly as he knocked on the door, which you had left slightly ajar in the hope of giving yourself some warning of his arrival, but you still jumped a little.
‘Come in,’ you smiled brightly, preparing yourself to pretend that everything was normal and last week had never happened, but you still felt yourself blushing as Namjoon shut the door behind him and sat down on the chair in front of you. He was incredibly handsome, anyone could see that, but having him sitting a few feet away was totally different to having him in your classroom with fifteen other students between you. From this distance you could see exactly how soft his lips were, and how his eyes reflected the afternoon sun.
‘Coffee?’ you said abruptly, standing up from your desk too quickly.
‘Yes please,’
You stood with your back to him as you prepared coffee for the two of you. Your pulse was racing now but you did your utmost to ignore it, even though your hands were shaking a little as you heaped the grounds into the cafetiere which made the spoon tinkle against the glass.
‘How are you, Namjoon?’ you said, forcing your voice into some semblance of calm.
‘Fine, thank you.’
There was a slight pause, and he shifted in his chair as you turned back to him and set the cafetiere on the bookshelf beside your desk with a clunk.
‘I’m sorry if I made you uncomfortable last week,’ he said, and he looked sincere as he gave you a half-smile that made dimples appear in his cheeks. ‘It’s just that I was interested. Your lecture was great.’
You hadn’t been expecting that. In truth, you had been uncomfortable when he left, but it was your reaction that had caused the problem rather than his behaviour. You had never in your life had that sort of interaction with a student, or...anyone really, and the knowledge that he could have that effect on you made you shiver slightly, but not with fear or disgust. There was no way you could admit that to Namjoon though, not while he was sitting there in front of you. You opened your mouth to say something, but no words came out and you closed it again, choosing to look at your computer screen to buy a little time - though your eyes were unfocused as you aimlessly scrolled down the page. The seconds ticked by with neither of you speaking and the atmosphere seemed to gather like a cloud in the room. One of you would have to break the tension that was pulling tighter and tighter between the two of you, either by speaking up or by leaving; you had a strange certainty that it wouldn’t be him.
‘It’s fine,’ you said in a small voice, turning back to him.
Namjoon raised his eyebrows and leaned back in his chair, which creaked slightly. Your breath hitched in your chest as he looked at you appraisingly, like he was sizing you up as he ran a hand through his hair. He didn’t say anything though, and you fought with your instinct to start fidgeting or chattering inanely, anything to pierce the silence that was heavy in the air between you, and settled for looking down at your clasped hands.
‘So why haven’t you looked at me since then?’
Your breath caught in your chest. You didn’t realise you’d been that obvious with how carefully you’d avoided Namjoon’s gaze, and it hadn’t even crossed your mind that he would have noticed. You were just his lecturer, after all - he probably had girls fighting for a date with him.
‘I - haven’t I? I’m sure I have! Maybe we’ve been taking it in turns to look and keep missing each other?’ you blustered, trying to joke with him. He smirked a little, but you quickly shut up when you realised that he wasn’t going to laugh along and silently cursed yourself for being such a fucking dork.
‘Maybe,’ he said, after a pause. ‘Or maybe you’re lying.’
He stood up from the chair and you thought for a moment he was about to leave, but then he splayed one hand on the desk and leaned over you like he had last week, taking your chin in the other. You froze as a mixture of fear and powerful lust rushed through your whole body; his hand was so warm on your face and you breathed in the scent of his cologne.
‘Are you lying, Y/N?’
He cupped your chin, gently lifting your face so you were looking right at him, and smiled at the way your eyes widened, his dimples carved deeply either side of his perfect lips.
‘No!’ you squeaked, knowing in an instant that you had given yourself away.
Namjoon brought his face so close to yours that you could feel his breath on your skin.
‘Another lie,’ he muttered.
You thought for a moment he was going to kiss you and licked your lips involuntarily, but he just chuckled and gently guided you around your desk to sit on the edge of your desk in front of his chair. His long fingers encircled first one ankle, then the other to lift your legs and rest your feet on the arms of the chair, so that you were sitting with your legs bent in front of him. You blushed deeply and looked away from him, but nothing in you wanted him to stop what he was doing.
He pulled the hem of your dress up over your thighs to gather at your hips and held it there with one hand, pushing your thighs apart with the other and standing between your knees to stop you being able to close your legs. Your mouth opened automatically but no sound came out as you looked up at him standing over you. His gaze travelled over your eyes, your cheeks, your lips and down to your throat, your collarbone, seeming like a physical touch which was then mirrored by his fingertips brushing over your face, making goosebumps rise all over your body despite the heat that had ignited between your legs. You felt yourself starting to melt at his touch and sighed as, like last time, he gently pressed on your bottom lip to get you to open your mouth a little further, still standing with your legs either side of his hips, and touched the tip of his finger to your tongue. Without thinking, you closed your lips around his fingertip and swiped your tongue over it as a powerful rush of arousal coursed through your veins and you clenched your thighs involuntarily. He chuckled softly and tutted, ‘Dirty girl.’
Namjoon slipped his middle finger into your mouth to join his index, his other hand gripping your thigh tightly. Your eyes fluttered closed as he pushed his fingers deeper between your lips, stroking over your tongue to let you suck on them softly, and you couldn’t help but let out a quiet moan, your breath sighing over his hand while your tongue danced over his fingertips.
‘You like that, don’t you?’ he said, just loud enough for you to hear. ‘You like my fingers in your mouth.’
You groaned an affirmative, squeezing your thighs around his hipbones again. The thought drifted across your mind that you’d have bruises there the next day, and another shock shot through you at that idea. You had loved seeing your body marked by your lovers in the past, owned, the evidence of their desire for you blooming in the dark bruises on your skin.
Namjoon growled under his breath and started to thrust his fingers slowly in and out of your mouth, pushing a little deeper each time, and you inhaled sharply as his other hand slid up your leg to stroke gently against your pussy, separated from his fingertips by the thin cloth of your underwear. Your eyes shot open again as you felt the gentlest touch trail the length of your slit, achingly slowly, stealing the breath from your lungs as Namjoon’s fingertip brushed against your swollen clit through the material.
‘You're soaked for me, Y/N. Tell me you want me to touch you.’ He pulled his fingers out of your mouth with a wet pop and you could hear how shaky your breath had become, your heart pounding in your chest. You couldn't speak, just stared up at him and whined softly at the sudden loss from your mouth; your underwear was wet with your arousal and you wanted nothing more than for him to touch you, desperate to relieve some of the tension.
‘Tell me, or I'll stop right now. I need to know you want this,’ he said, his hand stilling. Namjoon looked down into your eyes, and you knew you’d have to answer him sooner or later. You felt like you had never wanted anything so badly, but deep down you understood that he was giving you a choice. Back out now and preserve your professional dignity, forget this ever happened, chalk it up to a minor indiscretion born of loneliness and frustration - or give in to temptation.
You paused at his words, but nothing entered your mind except your burning want for the man standing in front of you, the need to jump in headfirst and give him anything he wanted to take from you.
‘I...I want this. Please,’ you whimpered, ‘please don’t stop.’
‘I thought so,’ Namjoon murmured.
Your hands gripped the edge of the desk as he undid the buttons of your dress one by one, down to your waist, but you couldn’t take your eyes off him. His eyes were a warm, dark brown when he wasn’t looking at your face, but you knew that as soon as his gaze fell on you it would feel like a static shock. At this distance you could see several tiny scars in his ears where he’d had them pierced and the very beginnings of black roots as his blonde grew out. Namjoon pushed the dress back over your shoulders to expose your chest to him and hummed appreciatively as you instinctively brought your shoulders back a little, pushing your breasts up. Somehow, it never occurred to you to be shy or try and cover yourself - the thought didn’t even cross your lust-addled mind. All you could think of was how much you wanted Namjoon to caress you all over, to touch you, to make you his, and you didn’t even care that you were in your unlocked office on a Friday afternoon when anyone could walk in.
Namjoon reached around and undid your bra with one hand, making goosebumps rise on your back, then pushed the cups up to reveal your breasts. Your nipples had already hardened in anticipation of him touching you, which hadn’t escaped your notice as the fabric of your bra had rustled over them.
‘So pretty,’ he said, almost to himself as he leaned back a little and gazed down at your body. ‘So pretty, Y/N.’
He didn’t take his eyes off your face as his warm hands cupped your tits and pushed them together slightly, as if he was feeling how firm they were, and then he brushed his thumbs gently over your nipples; you gasped as you felt your pussy tighten in response.
‘That feels good, doesn’t it?’ he said with a smirk.
You just nodded, your eyelids fluttering, and when he did it again you couldn’t help but let out a quiet moan. Your nipples were so swollen and sensitive that every circle of his thumbs sent a shock straight to the building ache between your legs, and with your thighs either side of Namjoon’s hips you had the urge to wrap your legs around him and pull him closer to you, so that his now-obvious erection would sit snugly against your slit for you to grind on as he played with your nipples. As if he’d read your mind, Namjoon moved his hands from your tits to gently push your knees further apart, spreading your legs for him, and rested one hand on your thigh as the other came back up to your face. This time his thumb stroked your bottom lip delicately and you opened your mouth automatically as you looked up at him.
‘Wider,’ he said, and you obeyed. ‘Good girl.’
Namjoon pushed two fingers into your mouth, the same way he had earlier, and you weren’t shy about swirling your tongue over and between them, sucking them unashamedly. You heard his breathing hitch a little and gasped around his fingers, but as his other hand slid up your thigh again you let out a louder groan that had him gripping your leg tightly.
‘You need to be quiet.’ he said.
You tried to nod, but he pulled his fingers out of your mouth and said, ‘Don’t make a sound. Don’t moan, don’t say my name, nothing. I’ll stop if you do. Do you understand?’
Your body sagged a little as a fierce lust burned in your veins, seeming to race through your body to add to the aching in your nipples and between your legs, and your hands gripped the edge of the desk hard. You had never been a screamer, but you weren’t used to being silent either. This might be a challenge. You just nodded, so desperate for him to touch you that you would have agreed to almost anything.
Namjoon’s fingers were back in your mouth before you could say anything, and you jumped as his other hand resumed its featherlight stroking of your slit, up and down, up and down, before you felt one finger lift the seam of your underwear. He paused here and cupped the back of your thigh - you didn’t think twice before raising your hips and allowing him to pull your soaked underwear swiftly down your legs. He lifted your ankle to slip them off and the cool air caressed your dripping slit for a moment before Namjoon’s fingertip started probing your folds, just as you laved your tongue against the fingers in your mouth.
‘You’re so fucking wet,’ he growled, and you blushed again - you could feel the slick slide of his fingers over your slit as he parted your lips gently to stroke all the way from your opening to your clit. ‘And you smell so good.’
Namjoon looked down into your eyes as he began to rub tiny circles around your swollen clit and it was all you could do not to whimper around his fingers. The smirk was back on his face, his dimples reappearing either side of his dusky pink lips. He was loving this, you realised dimly, having you totally under his spell, and his circles increased in pressure at the same time as he pulled his fingers gently out of your mouth to squeeze one of your nipples between his thumb and index. This time a shuddering gasp escaped you and you involuntarily bucked your hips, urging him on.
‘I thought I told you to be quiet,’ Namjoon murmured, and you just nodded dumbly. He can’t stop now. Your back arched as he dragged his finger down your slit again and you felt it breach your tight hole, but you were so desperate for him to touch you that you held your breath without meaning to. He curved his fingertip to press against the place inside you that made your whole body tense up and he massaged it firmly, tweaking your sensitive nipples in turn; your thighs clenched around his hips as you fought to keep yourself silent, but as the pleasure Namjoon was giving you mounted you couldn’t help moaning for him.
Without missing a beat, Namjoon said, ‘Put your fingers in your mouth, Y/N.’ You looked up at him as his hands stilled, and he did nothing but gaze back at you with his deep brown eyes. Haltingly, you brought your right hand to your mouth and he said, ‘That’s right. You can’t seem to be quiet without something in your mouth, can you?’
You hesitated, then opened your mouth and pressed two fingers against your tongue just like Namjoon had; this felt different, though. It made you a little shy to be sucking your own fingers in front of him, but that feeling disappeared as soon as he widened his eyes a little and bit his bottom lip at the sight. The lust evident in his momentary change of expression had you melting with desire and you pushed your fingers further into your mouth, eager to obey.
His finger flexed in your pussy as he eased another inside you alongside the first, and your walls clenched so tightly that he hissed, ‘Good girl, Y/N, such a good girl for me.’
Another flood of warmth rushed through you at his words, making your already sopping cunt gush and squeeze around his crooked fingers, but your fingers prevented you from gasping out loud - just as Namjoon had wanted. His other hand drifted from your nipples down to your slit, and he licked the tip of his thumb before touching it to your aching clitoris. It was as though an electric current had passed through you; your chest heaved and your hips rocked towards Namjoon as if begging him for more, and if your fingers hadn’t been between your lips you probably would have. With two of his fingers pressing up inside your pussy, massaging your most sensitive spot with every pass, and his thumb rubbing tight circles into your clit, you felt the pleasure he was giving you building into a fire that ran through your whole body to end in your dripping cunt. You could feel how swollen your clit was as his thumb dipped to your opening to spread your wetness between your lips before running back and forth over your clit and your head tipped back - you were panting now, and you knew you were close to falling apart.
He seemed to know it as well, because as his fingers fucked into you harder he was looking down at your body and he swore under his breath.
‘Fuck,’ he bit his lip again, as if stifling a growl. Your breasts jiggled with the movement of Namjoon thrusting his fingers in and out of your warm, wet pussy, but as Namjoon glanced up and saw the expression on your face he slowed down almost to a halt. You raised your head and looked up to see him smirking again.
‘You’re going to come for me, aren’t you?’ he murmured, and his voice was like velvet. ‘You’re going to come all over my hands, Y/N. I can feel how much you fucking love my fingers deep in your pussy.’ He reached up to grip your right hand and pulled, so that your fingers slid out of your mouth.
‘Say it,’ Namjoon said.
‘Please...please,’ you whimpered, almost pleadingly, and swallowed hard. ‘Please, I’m so close.’
Namjoon pushed your fingers back into your mouth with a twist of his lips and restarted his rhythm of fucking you with his fingers and sliding his thumb over and over your clit. Your walls were so tight around him and your tits bounced in time with his movements; you looked up at Namjoon, now unable to stop yourself letting out tiny muffled moans which nobody but him would be able to hear. You were agonisingly close, and letting your eyes shut you felt yourself pass the point of no return.
‘Come for me, Y/N, come on my fingers,’ Namjoon coaxed. ‘Good girl.’
The pressure that had mounted inside you broke in a crashing wave of pleasure that flooded your body, all your muscles tensing as you came hard. You were vaguely aware of Namjoon saying something like ‘fuck, yes,’ as your spine arched; your cunt spasmed around Namjoon’s fingers even as he flexed them inside you, rubbing circles around your clit to prolong your orgasm as long as he could, and you shuddered with each shockwave that pulsed through your veins.
Once you’d come down, Namjoon slowly withdrew his fingers from you, making you gasp and shiver a little, and your hand was gently guided away from your mouth. There was a pause, a rustle - your eyes were still closed and you jumped slightly when you felt something soft brush your fingertips. Dazedly, you opened your eyes to see Namjoon still standing over you, a slight smile on his face as he wiped your fingers clean for you with a little square of fabric, then tucked it into your hand. His hair had started to escape its neat styling and one platinum lock was loose over his forehead, but he didn’t seem to notice as he lowered your ankles one by one to let your shaking legs rest, then tugged your bra down to cover your breasts and rebuttoned your dress. He wasn’t rushing or in a hurry to leave - he took his time with you, bringing you back down to earth one step at a time, and your mind was so clouded with a post-orgasmic haze that you could do nothing but gaze at his eyes, his nose, his lips.
Once he’d finished neatening your clothes, he lay his hand on your cheek. It was warm and reassuring in its weight on your skin, and your eyes closed for a moment. Namjoon paused, looking down into your eyes, and seemed like he was about to speak before he ran a hand through his hair, straightened his collar and turned away from you to open the door.
‘Thanks for the coffee.’
Out of the corner of your eye, you could see the steam rising in ribbons from the spout of the cafetiere.
