𐙚 previous + next 𐙚
Big, big, big.
You let out a whimper, doe eyes rolling up to look at the man peering down at you. Your lips were wrapped firmly around his cock, struggling as he inched himself further and further into your mouth.
So big.
He was so damn big.
From arms to chest, it came as no surprise that Kim Mingyu was a man that worked hard for his body. He tended to coup himself up at the gym, spending hours upon hours lifting weights to gain the muscle he had acquired over the years. As expected, his cock was larger than most, if not, the biggest you have ever seen and the biggest you could have ever possibly imagined. Despite hearing the constant gossip amongst the girls on campus, you have finally gotten a chance to see for yourself and needless to say the monster cock rumors were true.
You have not a clue how you managed to find yourself in this position. In fact, you actually had no clue how you’ve been managing to find yourself in a lot of positions lately. After your escapade with Jeonghan a few days before, it left you excited, eager, and ready for more. You had always been one for learning new things and that intimate experience with him had opened up a whole new world for you – one in which you have never ventured in before.
You squeezed your eyes shut as you did your best to take what Mingyu was giving you. He was only less than half way in and there was still so much more to go. It was impossible. You were sure of it.
It would never fit.
Mingyu however, despite your idling thoughts, loved a good challenge. He knew you could take it. Maybe not today and maybe not tomorrow, but he was sure that with just a little bit more practice, he could train you to take his cock with ease.
“Relax.” He said monotonously. His eyes were focused on where his length disappeared into your mouth, a groan forcing to escape from his lips. “You’re fine.” He reassured you as he stilled his hips while you gathered yourself. “Just breathe.”
Listening to him, you took slow breaths through your nose while you adjusted to the foreign feeling of something in your mouth. If it wasn’t his length that killed you, it would most definitely be his girth. It had only been a few minutes and your jaw was beginning to ache already.
It was painfully obvious that you have never done this before and it was embarrassing to say the least. You were sure that other girls in which he has been with managed to take him easily without any complaint, so much more different from you and your lack of experience. For some reason you had the sudden need to show him that you could be just like those girls, maybe even better.
Making a decision that you were in fact not ready for, you rested a hand on Mingyu’s thigh and attempted to slide your mouth further down his cock. However, you definitely seemed to overestimate your abilities as you slightly gagged when it went a little too far and caused you to let out a muffled cough.
Furrowing his eyebrows, Mingyu made a sound of disapproval as he watched you. He fisted at your ponytail, using your hair as leverage to gently pull you up and off of him.
A whine escaped from your lips as soon as his tip slipped out. In such little time you had found yourself used to the feeling of something occupying your mouth and now that it was gone you didn’t enjoy the loss. You tried to dive back on him, but you were met with resistance instead. Mingyu’s hand snaked it’s way to your face as he lent forward on the couch to be somewhat eye level with you.
“What did I tell you?” He asked with a stern voice. His fingers gripped at your jaw to keep you in place, making sure you didn’t shy away from the angry look he was sending your way.
Your eyes were quick to fill with tears, not liking both his tone and the sudden confrontation. You were never the type of person who was fond of getting reprimanded – not when you were younger and not now as well. You tried to avert your attention to elsewhere, but Mingyu tsked in dissatisfaction.
“Nuh-uh. Look at me.”
You typically tended to listen very well in any circumstance so needless to say it came as a surprise that you were acting a little out of the ordinary today. Your behavior was almost beginning to get somewhat bratty and Mingyu could only hope that it wouldn’t continue.
“What did I say?” He asked again. “Before we started this. What did we agree on?”
You bit your lip, suddenly nervous. “To take it slow.” You answered softly, your voice fading out as you spoke the words.
“Mhm.” He nodded. “So why are we rushing things huh? I told you it’s not going to happen in one day, didn’t I?”
You shrugged, vaguely remembering that it took some time convincing Mingyu to allow you to suck him off. It was your first time doing this, let alone the second time doing something sexual altogether and he knew that. He made it very clear that if this was going to happen, it was going to go his way. However, seems like you had the wrong idea in mind for “his way” because according from what you’ve heard about Mingyu around campus, he never goes easy. It was always endless gossip about fast and hard. Rough and messy. Mean and humiliating.
This was nothing like what you originally imagined it to be like, but quite frankly maybe that was exactly what you needed. Maybe Mingyu knew your limits better than you knew your own.
“M’ sorry.” You muttered as you looked down to fiddle with the ring on your finger.
Mingyu took a few seconds to respond, examining you instead. You didn’t take much of a liking to the way his eyes felt on your figure, causing you to shift around. He eventually opted to nod in response as he let go of your face.
For a second you thought he was done. That you blew your chances in learning how to give a blowjob and that was it – but instead he grabbed a cigarette from his pack, sparking it up and taking a long drag. Blowing the smoke up into the air, he leant back on the couch with his legs spread wide open. His cock stood tall in all it’s glory, hard and coated from your saliva. “Let’s try this again.”
You perked up immediately at the statement, sitting on your knees between his legs. The carpet dug into your skin, but you didn’t take any notice to the scratchy feeling, instead giving the man before you your undivided attention. He was indulging you and better yet, corrupting you.
With a hand resting on the back of your head and burning cigarette in the other, Mingyu led you back to his cock. He let his tip rest at your lips, swearing under his breath as he struggled hard not to slam right into your mouth from the sight of your innocent doe eyes peering up at him.
Never in all of the years he had known you, did Mingyu think you two would ever be in this position. He was a menace in the bedroom, a hard dom and on certain occasions a brat tamer. He normally went for the girls who he could throw around. The ones who would get on their knees for him with just the snap of his fingers alone and the ones who wouldn’t care if he didn’t hold back in which he never planned to do in the first place.
But this was different – this was you.
He wanted to move slower because although you didn’t know much about the joys of sex and pleasure, he did, and he also knew that you weren’t the type of person who could be easily thrusted into it. You were far too sheltered, far too nice, and far too pure.
“Gyu….” You whined, teetering on the edge of slight impatience. He was taking too long and you were beginning to get shy under his gaze.
The hint of desperation in your tone quickly snapped Mingyu out of his daydream and he jumped back into action soon after. “Open.” He ordered, to which you obeyed.
Your lips parted, mouth awaiting to be stuffed yet again. You almost looked like a puppy eager for it’s treat and Mingyu struggled to bite his tongue to hold back the degradation wanting to escape.
If it was anyone else – oh if it was anyone other than you, he would have made them cry. He would’ve made them beg, and he would’ve made them show him how much they wanted it. It was quite shocking what affect you had on him. Only you had the ability to make Kim Mingyu go soft.
“Good girl.” He praised, noticing that you followed his instructions well.
You found it rather difficult to contain a moan, your thighs pressing together as the words floated straight to your head. Mingyu raised an eyebrow, trying not to laugh as he took notice of the way you enjoyed being praised, just like he assumed you would.
The boys were always hard to read – all thirteen of them mostly silent and kept to themselves for almost the entirety of your life in which you’ve known them. However, for them, you were an open book. One in which they have read every single page to about a million times.
“Stick out your tongue.” He instructed.
Almost immediately, it darted out of your mouth causing dirty thoughts to flood the boy’s mind. You looked as if you belonged on the thumbnail of a porn video and for a second he seriously considered snapping a photo to keep for his eyes only.
Groaning, he shook his head. “You’re killing me Y/N.” With a now clear mind, Mingyu slapped the tip of his cock against your tongue. Your eyes narrowed in on it, the want and need to have it deep inside your mouth as opposed to him just teasing you.
But you were good and good girls don’t complain.
After what seemed like a lifetime, Mingyu finally slid himself into your mouth. He only allowed a good two inches in at first, slowly working his way up to what you managed to take before. The ache in your jaw began to make a comeback and you almost wished you were a hippo, for the first time in your life envying their ability to unhinge their own jaws.
You can take it. You can take it. You can take it.
Mingyu gently inched himself into your mouth little by little until he was eventually over the halfway mark. Yet again you took steady breaths through your nose to help calm yourself down as your eyes began to water. Pushing away the urge to cough you instead clutched the man’s knee, using it as your personal stress ball. The fogginess that was beginning to cloud your mind was progressively getting more difficult to ignore and you struggled to gather yourself as your thoughts drifted and you found it harder to think.
Mingyu steadied himself and locked his gaze on your face. He knew that look all too well – the one in which the lights were on, but no one’s home. He’s become quite accustomed to it, having seen it multiple times before with close to every rendezvous he’s had. This was the part in which he was supposed to humiliate and degrade. It was almost routine at this point. However, with one glance at the tears forming in your waterline, you just so happened to tug at his heartstrings.
“You good baby?” He asked, pulling a bit of himself out of your mouth to make it somewhat easier for you.
Barely registering his words, you paused for a beat to collect yourself before letting out a sound of assurance. Despite this however, Mingyu would seem to differ as the tears that were once threatening to fall surely enough went cascading down your face with just the blink of your eyes.
“You sure?” He asked again, refusing to move. The time he spent making you wait was driving you crazier by the minute and it didn’t help that he kept your ponytail wrapped around his hand to prevent you from moving.
You made a sound of approval yet again to give him the green light, this time being much more insistent with a little nod of your head.
You didn’t want him to stop. You didn’t want to stop.
With a sigh, Mingyu bit his lip hesitating. Fortunately for you though, with him being distracted by his own thoughts, he made the mistake of loosening his grip on your hair by the slightest. You were quick to jump at the opportunity that suddenly arose, seemingly not having learned your lesson before – the one that invisibly states “it takes time to take a dick this god damn big.”
Instead of slowly pacing yourself further down his cock, in alternative you forced yourself much too quickly to slide in two more inches. Although a miniscule number to what most people might think, especially the already experienced – you could feel the tip of his cock drag against the back of your throat, the feeling hitting you like a hurricane. Your tears made an appearance once again, except now moving much more quickly and frequently down your cheeks as you tried your hardest not to gag. Your breathing picked up to assist with your struggle, swallowing around Mingyu’s cock when you realized you couldn’t inhale or exhale through your mouth. You reached a hand out, squeezing the man’s thigh a lot harder than you had before. The back of your throat felt raw and for a second you thought you might have possibly dislocated your jaw.
Mingyu was quick to throw his cigarette down on the ashtray, leaning forward as soon as he processed your actions. You felt his hand thread through your hair, using it to get a grip and pull you off his cock. When the tip finally slipped out of your mouth, you instantly broke out into a coughing fit, no longer being able to contain it. Amongst your struggle however, to Mingyu’s surprise, you still seemed to be so persistent as your hand reached out to grip at the base of him despite needing a break.
The man clenched his jaw, leaning in close to your face. “I’m gonna kill you.” He muttered, keeping a hand on you to provide a sense of space between you and his cock that for some unknown reason you seemed so eager to get back to.
This was exactly what he didn’t want to happen. He gave you an inch and you took a mile.
“I can –,” You coughed, “I can take it.”
Mingyu scoffed at your words, running his eyes over you to take in your state. You were a little bit short of a mess. Your eyes were glazed over, tears running down your face, and voice hoarse. You definitely could not take it. At least, not right now.
“Y/N…” He started, trailing off when you rested your chin on his thigh while looking up at him. You were visibly deflating with each second that passed and Mingyu didn’t like that he was the reason for it. He knew you, and he also knew that you were trying your absolute best to be good for him. “Sure you can sweetheart.” He continued, striving to reassure you as he tucked himself back into his sweatpants. “But maybe some other time, okay?”
You were not very happy with his answer and the whine of defiance that escaped your mouth let him know that. “Please Gyu, please.” You begged. “I’m fine, I promise.” Your pleas fell on deaf ears as he ignored you, already knowing that you were going to try and get him to change his mind, but it was already set and the decision was final.
Scowling at the lack of his attention, before you could think, your hand came down on his leg rather hard, the smack ringing throughout the room.
“Hey.” Mingyu warned, tilting his head with his eyes set on yours sternly. “Quit it.” He said firmly, speaking through his teeth.
Your own eyes held his fierce ones, eventually backing down with a huff when you came to the conclusion that you weren’t going to win. Suddenly refusing to look at him, you abruptly got up from your spot between his legs. He watched you carefully, stare following you as you got seated on the couch farthest away from him in annoyance.
“Y/n…” He spoke your name, attempting to get your attention. You turned your head further to the side, ignoring him and not giving in. “Y/n.” He said much more strongly, however you still refused to to look in his direction. He let his gaze linger on you for a bit longer before chuckling to himself. “Brat.” He muttered under his breath, going to grab another cigarette to let off some steam.
Silence filled the room, you mostly keeping quiet because you were angry and him because he knew you were just being stubborn. Mingyu could not deal with that right now – at least, not in the way he normally would if it had been any other girl in your position.
You glanced over at him from time to time, looking away quickly whenever his eyes found yours. Your body was starting to get a little sluggish and for some odd reason your brain was fuzzy, but instead of making him aware of that, you kept it to yourself. The last thing you wanted to seem was weak. Mingyu however, is a lot smarter than that, especially in this category. He clocked the minor subspace you were slipping into as soon as it made an appearance, already knowing that there was a high chance in which you would fall into it knowing the person that you are.
Most virgins do anyways.
You nibbled on your bottom lip, propping your arm up on a cushion to lean against it. The only thing you craved at the moment was warmth and comfort. You would have went running to Seungcheol and Jeonghan like you typically did, the oldest two always being able to fill that void – however instead you stayed glued to your spot on the couch.
You wanted Mingyu at the moment and only Mingyu.
Your eyes seemed to do the speaking for you, not realizing that you were staring at him with a sad and defeated expression. Mingyu scanned you up and down, finding it hard to resist your infamous puppy dog eyes as unintentional as they were. Sighing, he beckoned you over with the nod of his head. “C’mere.”
You wavered, only jumping into action when he raised an eyebrow at your hesitance. Crawling forward on the couch, you perched yourself right beside him and curled up into his side. His arm wrapped around your body, the size of him compared to you being able to provide you with a sense of comfortability.
Silence filled the air once again as soon as you were in his arms and the only sound that could be heard was him taking an occasional drag of his cigarette. You had gotten acquainted to the smell over the years, the scent of it no longer bothering you. Watching the smoke linger in the air with each puff he took, a question lingered on the tip of your tongue.
“Can I try?” You asked, voice hopeful.
It took him by surprise to say the least. Never once have you shown any interest in the bad habits that himself and the boys picked up throughout the years they got older. Hell no, was the answer he was looking for in particular, but deciding you didn’t exactly need that blunt of a reply at the moment, he found something much nicer to deny your request. “Let’s move one step at a time hm?”
You nodded, understanding that he had already indulged in one thing new that you wanted to try today and now you were asking for too much. “Okay.”
With the conversation you two were having come to an end, Mingyu was finally able to have a moment of peace. He was a man that loved to party and loved playing music at full blast, however he also enjoyed the moments in which he could just let all the thoughts in his brain drift away.
It seemed to be different for you however because while his thoughts were relaxing, yours were spurring. You kept on taking small glances at his face, wanting to speak up, but also not bringing yourself to disturb his peace.
The ring on your finger went round and round in circles as you couldn’t stop fiddling and with each move of your hand it was driving Mingyu out of his comfortable state. Finally, after you had accidentally hit his stomach one too many times, he couldn’t bite his tongue any longer. “Spit it out Y/n.”
You snapped your head up at him, not have expected him to speak. “Uhm….” You hesitated asking the question.
Another question. Mingyu hated questions.
“Was I –,” You stuttered, “Was I good?” Your voice was small and fragile. For a split second Mingyu thought you were going to breakdown into tears due to your own self doubt. He took in your composure, knowing exactly what your question entailed – you wanted to hear one thing in specific, the one thing you’ve been so intent on trying to be throughout this entire situation.
“Mhm.” He hummed, bringing his hand up to your head to pet at your hair. His fingers laced through your locks, gently scratching at your scalp. “You were such a good girl for me.”
A rush of giddiness coursed through you, but you were quick to push it down as your worrisome thoughts still stayed. “Really?” Your voice cracking this time as you asked again.
Shaking his head in approval, Mingyu kept playing with your hair as he tried to ease your worries away. After some time, he stopped to kiss your temple. “The best.”
You resisted the urge to giggle, pushing your face into his neck as you suddenly went shy from his words. That was the only thing you needed from him for today and it left you feeling much more than content.
Oh how you loved being praised and oh how you loved being called a good girl, especially by Mingyu – and that’s exactly what you planned on continuing to be, his best girl.
I NEED A WHOLE PROGRESSION OF BAD NOY MINGYU AND HIS GOOD GIRL THIS IS RIGHT UP MY ALLEY THIS WAS SO GOOD
