Work Text:
You were sitting in your dorm room, a sketchbook settled onto your lap overtop of your fluffy blanket. Your laptop was beside you, quietly playing a drawing tutorial video. Hands moving carefully across the rough paper with the sharp led, you made sure to pay close attention to the steps.
A sudden knock on your door, quick and frantic, knocked you straight out of your own little world, and you found yourself moving to get up just seconds later.
No one should be knocking this late, but you had a gut feeling on who it was.
And just as you guessed, a sweaty and anxious looking Katsuki stood right outside your door, his tall and recognizable figure appearing from the darkness of the dormitory’s hallways once you twisted the doorknob open.
“Katsuki!” You exclaimed, happy to see him— before realizing how nervous or.. panicked he seemed. It didn’t take long for you to look him up and down, naturally scanning for injuries and wounds. But instead, your eyes landed on a bulge in his black basketball shorts.
“Oh—“
“I’m not apologizing, in case you were wondering. If you weren’t already awake, you wouldn’t have answered so fast.” He stated.
You smirked a little.
“Always finding ways to brush off the reason you come here.” You joked, knowing he, for one: had never come here for this before, and two: he was bad at communication.
You couldn’t and wouldn’t deny your growing nervousness the moment your eyes focused on his crotch, the mere sight making your thoughts spiral and spasm out. He seemed to be unimpressed, feeling all of these things tenfold.
“Shut your damn trap..”
You gave him a look.
“And can I come in?..” He mumbled, making your smirk collapse into a half-innocent smile. You nodded and moved aside, welcoming him into your cozy and comfortable space quite easily.
With you and Katsuki, simply being in each other’s presence was enough. You enjoyed each other’s company, whether silent or loud. So he wasn’t new to your room— but every time that familiar scent that checked itself off as you in his head met his nose, he could feel his heart beat just a little faster.
He seemed to feel awkward, standing near your bed and fiddling with his fingers. That was a rare sighting.
“Care to tell me what that’s about?” You asked quietly, gesturing to his boner. His brows furrowed just a little, and you carefully locked the door with a perfected dexterity. That involuntarily made him even more nervous.
“Tch.” Was all he could reply with, rolling his eyes and moving closer to you, caging you into the corner of the room by your door. You held your ground and stood just as close to him, not backing away for one moment. He looked down at you for a second, but it felt like minutes.
“You’re the damn reason I got this stupid shit in the first place. And it’s not like I can do anything about it, I’m not trying to blow my dick off.” He admitted quite easily, contradicting his earlier anxiousness.
Well, he had a point. His heat quirk might just explode his baby-maker, had he tried to relieve himself. Without help.
With a small yet powerful smile, you placed a hand on his chest and pushed him back onto the bed. His eyes widened immediately, feeling that unfamiliar vulnerability with you that he couldn’t find anywhere else. But with you, it was.. pleasant.
“You know, a warning would’ve been nice. I was in the middle of drawing, right before you popped up."
He rolled his eyes, looking anywhere but at you.
The whole situation you were in right now was pretty nerve wracking, especially because this relationship was new for the two of you— as in like, two weeks. Most couples waited longer than that, at least the ones in their school.
Excluding Denki and Kyouka.
“I guess I can help. But the only rule is you can’t pretend to be a top. It’s very obvious you aren’t.” You teased.
He scowled, eyes being pulled to yours with that comment. “Fuck off, don’t say shit like that.” He barked back, but really— he didn’t need to hear you say that because it was not helping with the tightness of his pants.
Katsuki didn’t.. often have a boner, it was a rare moment for him— mainly because until this third year of attending U.A, he hadn’t found a reason to get one in the first place. Until he realized having a partner wasn't so bad if it was you.
You smiled at his reactions to your teasing, feeling satisfied with them. Not that you had a lot of experience in this department, but surely more than he did. After the thousands of fan fictions you’d read, how could you not know some things?
Your hands snaked onto his biceps, moving lower and lower until finding the smallest point of his wrists. His eyes were intently locked on you as your pressure on his arms increased immensely, surely keeping his wrists down against the fluffy covers of your bed.
“Just tell me when you want me to stop, okay?” You asked, receiving a small nod in return from Katsuki.
You wanted to take it relatively slow with him, since he’d surely never done this before. Fortunately, it came up in a drinking game with 1-A once that he’d never jerked off before, simply because of his quirk. It was a huge risk, one you wouldn’t take either.
But you wouldn’t go easy on him. He wouldn’t forget his first time.
As you carefully climbed onto him, you could feel his rock-hard erection pushing against your shorts. The feeling made your stomach do five flips in a row.
Though it seemed to affect him more than it did you. He let out one of those noises as if he was holding in even more noises, a mix of a gasp and a small groan. It made you smirk a little more, and gave you the confidence to slowly grind against him.
His head rolled back, along with his eyes. Hell, what could he say? He’d never even cum before, this must’ve felt like entering a different dimension if it was the first time in seventeen years that he’d gotten any friction.
Katsuki wasn’t the type of guy to be vulnerable with anyone, either. He knew he could trust you, but that ‘don’t show weakness’ mindset had been ingrained into him a long time ago. So, quickly, he stopped his facial reactions to the grinding and spoke up.
“Hell’s with all this build up? Just get to the fuckin’ point.”
You smiled. “I wanted to make your first time special. Not rushed.”
His cheeks heated up a little— (more than they already were) and he looked away, shutting one of his eyes tightly for a moment as you ground against him harder. A small gasp was elicited from him as well.
He squirmed a lot under you. Every move you made seemed to come with a jerk of his head or a twitch of his hands. That only gave you more confidence that you were doing this right, and you decided to pause just before he came.
Katsuki groaned and looked up at you, trying so incredibly hard to look angry, when he really just looked disappointed and desperate. “The hell was that for, dipshit?” He asked, tone the same as always, with just a little more breathlessness.
“Like I said, I’m not rushing this. And the more you complain, the longer I’ll wait to let you cum.” You replied, moving lower down the bed to snake a finger or two under the hem of his shorts, removing them slowly and throwing them to the side.
Now you could see his boner even better. And damn— you were expecting Katsuki to be big, but not.. this big.
Your curiosity got the best of you, and you pulled his boxers off, finally getting to see his length in full. Your eyes widened once you saw it, wondering if you’d be able to take this much inside of you.. especially since it was your first time as well.
“Damn.” You said quietly, then smirking a little and moving your hands up his thighs incredibly slow. With his hands free now, he tangled a hand in your hair and lifted your head, and before you could protest, his dick slammed into your throat, making you gag naturally; followed by a pointless gasp for air.
“Sorry.” He muttered out, voice sounding higher and more tense than usual. You smiled— at least as much as you could right now— and rubbed a thumb against his thigh, as if to say you didn’t mind this anyways.
It took a moment to get used to, but now you were apparently doing fucking amazing because he was unable to stay silent the whole time, whether it was whimpers or groans or something in between.
“F— fuck.. I’m.. it feels like I’m about to..”
Well of course he didn’t know what it felt like to cum. You rolled your eyes a little, feeling his hand loosen in your hair and taking the chance to sink your jaw down with onto him as he came.
He turned his head to the side, trying to bury it into the pillow beneath as his cum pumped into your throat.
Finally, when you lifted your head off of his cock, a thick white substance oozed out from your mouth, dripping onto your chin, neck and even his thighs. The little remains of his mess around your mouth made him hard all over again, and he was panting out little apologies.
You smiled and climbed up to his level, still above him. Your hands carefully moved over his shoulders and up to his face, cradling it and rubbing a thumb against his red-tinted cheek. He looked up at you and caught his breath, finally getting to see your cute face up close. The face he’d just made his mess all over.
“Don’t apologize, baby. You’re just gonna have to cum until you can’t anymore if you wanna go and pull shit like that.”
His eyes widened, and he seemed to realize how deep in shit he was now. The tips of his ears slowly grew red as well, thoughts of you doing this to him all night taking over every part of his brain.
You moved next to him, trying to adjust your positions to the point where he was in your lap and you could jerk him off from behind. Finally settling down once you were able to lift his limp body up for a moment, you snaked a hand around his waist and traced little patterns on his skin.
Your other hand moved down to his throbbing dick, fingers wrapping around the base. Finally able to speak, Katsuki gasped a little and tried to protest. “What the hell, a— again?!”
You rolled your eyes. “We just discussed this, Katsu..”
He tensed up a little and wished he could scowl at you, though the back of his head was now resting against your shoulder.
When your hand began to move up and down again, he almost felt pain— the feeling of going again so soon after his last orgasm was overwhelming, overstimulating. But it was clear you didn’t care. And he deserved it after forcing your mouth around him like that.
“I— fuck.. I’m.. I’m sorry just.. ah— oh fuck.. don’t.. don’t make me do this all night..” He begged, making your brows furrow.
“I’ll do what I want to you.”
If anything, that made his cheeks even redder and his dick even harder. He’d never told anyone whether he was a bottom or a top, because frankly, he had no clue. How could he know when he was a virgin? But it seemed that one round with you proved he absolutely wanted to be the bottom, at least mostly.
Your hand quickened, and he turned his head to try and bury it against your neck— but found he still couldn’t. As a substitute, your free hand moved to hold his hand. His sweaty palm almost completely enveloped yours, and his fingers tightened around yours so hard it was almost painful. You wouldn’t be surprised had his knuckles turned white.
He moaned quietly and weakly as his head rested against your front, making you smile a little bit and quicken up again. His head jerked forward. “Oh— fuck’s sake.. I’m gonna.. aah— oh my god, what are you doing to me?” He asked as if this was a whole new world. Well, it probably felt like one. You wouldn’t know.
“Shh..” You told him, kissing the top of his head gently. You could feel him getting close again and sped up, making him shoot his second load onto his stomach and your hand. You smiled, proud of yourself.
“Good boy.”
His eyes widened more than they ever had at that, and he felt something in his stomach flutter, before his eyes closed shut and he came a little more into your grip.
“Oh, so you like that? Slut.” You muttered, then kissing his head again and carefully moving out from your spot behind him. He rested against your comfortable pillows, loving how much they smelled like you.
He wasn’t unable to protest, he just wasn’t gonna stop you from praising and or degrading him. He learned he really liked that..
And before he could process any of that, he felt your lips on his lower body, cleaning up his mess with your own mouth. You looked up at him through your eyebrows, smirking a little as your tongue continued to lick up any remaining cum.
Now, once you’d finished his stomach, you cleaned up his thighs and the tip of his dick, making his head roll back against the soft pillows behind him. He seemed incredibly sensitive right now.
Then you started to climb onto him again, pulling off your shorts, and his eyes shot open to look at you. You were nervously placing yourself above his tip, and he seemed nervous too. “You don’t have to if you don’t want to—“ He started, but you cut him off.
“I do. I just.. it’s fine. I can take it.” You said with a little giggle, making his head spin and heart pound.
“Not the only time you’re gonna be saying ’I do’ to me.”
You looked up at him, shocked— then letting one small laugh slip again. He smirked up at you, before deciding that this was the perfect moment to guide you down onto him, his cock feeling like it was tearing into your pussy. You instinctively let out a moan, leaning your head back and shutting your eyes tightly. He did the same, both of you feeling as if you’d just gone through a magical portal.
”Oh— fuck, Y/n, you’re so fucking tight..”
He whimpered out as you adjusted to the length of him. Once you’d finally grown used to it after a few seconds, you slowly began to move up and down. He was unable to say much at all now.
But still, his hands moved to your hips and he rubbed his thumbs against your skin— despite looking like he’d just been stabbed.
Right now, not one thought could stay in his mind. He felt completely helpless and dumb, but the one thing he knew is that having you ride him felt like heaven.
You held in your whimpers as best as possible, since most of them were out of pain for now— and you didn’t want to alarm him. You needed to make his first time special, so you put your pain aside and began to move your hips as you rode him.
And after a little bit, the pain was gone. So now you could really give him the time of his life. Your small gasps and whimpers mixed with his, and when you did that thing with your hips and tightened around him, he found himself unable to do anything but feel tears prick at the corners of his eyes.
You noticed his eyes were watering, and almost felt proud of yourself— but wanted to make sure he was alright.
“Hey, you okay?..” You asked him, and he nodded profusely, his grip on your hips tightening again and helping you ride him.
You felt a whole new wave of pleasure come at that, and began to move quicker. Both of your moans combined and mixed together, and your hands sought out refuge at his own hips, leaning onto him just a bit.
“Ka— Katsuki, I’m gonna cum..” You whispered out, and he focused all his strength on his eyes to look at you.
“Me.. me too..”
Every word was panted out, and he gave you that look.. the one begging to finish inside. You nodded.
He came inside of you, more than before. You did at the same time, making you almost collapse onto him and breathe heavily against his chest. He seemed to be in the same boat, unable to speak or do anything at all.
Eventually, his arms wrapped around your waist once he felt himself get soft, and he helped you lift off of him. Your thighs were trembling at this point, and he almost felt bad. “I’m.. sorry— was it.. too much?” He asked, and you shook your head.
“No. Not at all.”
Your own hands wrapped around him, and his breath began to slow. “Okay.. but.. but, I got to cum more than you did.. that’s not fair.”
You felt butterflies at his response, knowing you’d picked a good one. It wasn’t often these days that people found partners who cared about giving just as much as they received, and that was important to you.
“I know.. but it was your first time, I wanted to make it special for you.”
He huffed. “It still can be.” He protested, slipping out from under you and flipping you over. Your eyes widened, but you still felt too weak to do anything. “Katsuki!—“
”No. Let me help you cum too.”
You bit back a retort, and he spread your legs open, eyes focusing on the wet mess he found in between.
“Damn.” He mumbled, as if seeing your pussy up close was like being inside of a rainbow or something.
Within seconds, his lips had found your skin covered in his very own fluids, his tongue pressing in between the folds gently. You cut off your own whimper and moved your hand into his hair, gripping it tightly— but not too tight.
”Ka— fuck, oh my god..” You tried to speak, but found that saying a whole sentence right now was close to impossible.
You’d never been eaten out before, and it already felt fucking incredible. Is this how he felt when you went down on him?
And then, he started feasting on you. An incoherent jumble of words occasionally escaped your mouth, but were mixed in with all of your little whimpers and moans. Your hand tightened in his hair, and he smiled against your wet pussy as he continued to eat you out.
Whatever he was doing, it was working— it was working so incredibly bad. It was like he was slurping spaghetti noodles down there.
You squirmed and arched your back, wanting more friction when that was impossible. He’d completely buried his face into your thighs now, leaving no room in between.
“Katsu.. ki!—“
Before you could warn him, you came all over his mouth, and he..
Oh fuck.. he wasn’t stopping.
“Nngh— Oh my fucking.. Ka— what are you.. holy shit..” You whimpered out, and his hands had to hold your thighs apart with even more force, your squirming and jolting making it hard for him to keep going.
For a first-timer, he was doing amazing. Like, perfect. His tongue knew exactly what to do, and combined with the small rubs on your thighs as he held them apart.. you were sure nothing felt better than this.
Katsuki didn’t stop until you’d came on his face about five times. By the second time, you were already unable to speak— so now, you felt completely limp and unable of anything at all.
“Found out what my new favorite food is.” He said happily, licking your cum off of his face as much as he could, rubbing the rest off with his forearm.
You looked at him, swallowing hard as you tried to speak— though nothing came out. He smirked and climbed up your body at an antagonizing slowness, his hands creeping up your thighs.. to your hips.. to your waist, and then one cradling your face, the other on the side of your neck.
“Can we do this every week?” He asked teasingly, then connecting his lips to yours. Once you’d finally found the strength, your arms wrapped around his neck and you kissed him back.
You nodded, and he smiled into the kiss.
By now, the sun had started to rise. He’d come at around 4:00 AM, and you’d been fucking until the sun came up. Well, it was worth it.
You were both dead asleep around 5:30, a few minutes after he cleaned you up with a warm, wet rag and dressed you and himself. You were too weak to do any of that yourself, and had a feeling that would linger over you even tomorrow.
He laid on top of you, body limp and heavy with his arms wrapped around your waist. Your own arms loosely hung over his waist, holding each other and soaking up the other’s warmth.
The next day, sometime in the evening, you had gone to the dormitory’s laundry room to wash your sheets and covers, and he found you in there— just as he’d guessed.
With a little mischievous smile, he leaned against the door and looked at you all fake-innocently.
“Wanna stain your mattress too?”
You rolled your eyes and smiled before tugging his wrist and pulling him to your dorm room.
