Work Text:
It was an ordinary Friday night for the students of Yuuei. After dinner, some had already gotten ready to head home and spend the weekend with their families, while others had retreated to their dorm rooms, already asleep. The rest occupied the common room as usual, spread out across the couches, the rug, and in front of the television, which was playing some random show that very few were actually paying attention to.
Quiet conversations, occasional laughter, and the clinking of glasses filled the room, creating the peaceful atmosphere that usually settled over the dormitory at that hour. Everything was exactly as it always was.
Except for two boys, whose presence seemed to completely disrupt the room's tranquility.
Bakugo remained seated on the couch across from them, his body stiff against the cushions and his arms crossed so tightly that the muscles in his forearms looked tense beneath his skin. His jaw stayed clenched, his gaze fixed straight ahead, almost intimidating, following every small movement without even blinking. It didn’t take long for anyone to realize that something was deeply bothering him, though no one was brave enough to ask.
On the smaller couch, Deku chatted animatedly with Half-and-Half. Sitting sideways, his feet buried between the cushions and his knees nearly brushing Todoroki's thigh, completely oblivious to the lack of space between them. He gestured nonstop as he spoke, just as he always did whenever he got excited about a story, his green eyes shining with enthusiasm and a broad smile lighting up his face. Every expression came accompanied by exaggerated hand movements, making it impossible not to pay attention to him.
Todoroki sat with impeccable posture, one arm resting along the back of the couch. His expression remained as calm as ever, but his mismatched eyes never left Izuku. They followed every word, every smile, every subtle change in his expression with careful attention.
Katsuki noticed, with growing irritation that made his stomach churn, that those eyes didn't remain fixed solely on the nerd's vibrant green ones. Every so often, they would discreetly drift down to his lips, lingering there for a few brief seconds before returning to the rest of his face, as though they were drawn to them. It was ridiculous. Absolutely ridiculous.
And yet Todoroki kept that damned peaceful smile on his face, nodding occasionally as he listened to Izuku tell his stories, as though nothing else in the world deserved his attention.
He saw Shoto lean forward, shortening the distance between them even further. The movement was subtle, almost imperceptible to anyone else, but enough to stir something uncomfortable inside Katsuki. His chest tightened with a strange mix of curiosity, unease, and a concern he couldn't even name.
Then that half-and-half idiot raised his hand. His long, slender fingers reached toward Deku's hair with infuriating gentleness, brushing aside a few rebellious strands that had fallen over his face and tucking them behind his ear.
Bakugo swallowed hard. His eyes followed those same fingers as they slowly slid downward, resting on the green-haired boy’s bare knee before gently pulling it a few inches closer. His throat instantly went dry as an unpleasant warmth climbed the back of his neck, making his jaw clench even tighter.
To Katsuki, it was painfully obvious what was happening. There was no room for interpretation. The closeness, the touches that were far too casual to actually be casual, the lingering glances... everything screamed the same thing. What enraged him wasn't just that it was happening, but that it was happening right in front of him, as though no one else besides him was capable of noticing.
His gaze remained fixed on the scene, heavy enough to bore straight through both of them. At one point, Todoroki looked up and met his eyes for a brief second. Those heterochromatic eyes stared directly into the crimson irises burning with irritation, seeing an almost tangible hatred within them.
Even so, he showed no sign of embarrassment. He didn't pull away, didn't remove his hand from Izuku's knee, much less increase the distance between them. He simply held the eye contact for a moment before returning all of his attention to the green-haired boy, as if Katsuki didn't even exist.
In disbelief, Bakugo tore his eyes away from the pair and scanned the entire room, looking for someone who shared his outrage. It was impossible that he was the only one seeing this. The scene was unfolding practically in the middle of the common room, in broad view, surrounded by their classmates, and yet no one seemed even remotely bothered.
Mina remained seated on the floor, using the coffee table for support as she carefully painted Jirou's nails, while Jirou watched with a distracted smile. Right behind them, Momo occupied one of the armchairs, calmly flipping through a fashion magazine while taking part in the girls' conversation, discussing clothes, trends, and other topics Katsuki considered completely pointless.
At the kitchen counter, Kaminari and Mineta noisily battled each other in a ridiculously childish game on the new video game console Minoru had received, alternating between complaints and exaggerated celebrations.
Nearby, Kirishima and Satou enthusiastically discussed the release of a new astronaut anime, debating theories with so much excitement that they seemed completely isolated from the rest of the room.
No one looked at the couch. No one noticed the touches, the closeness, or the lingering glances. It was as though the entire scene simply didn't exist for anyone except Katsuki, and he hated admitting that this irritated him even more.
Katsuki wanted to get up from that couch and punch the two of them until they separated, forcing each of them back to their own rooms. He wanted to embarrass them so thoroughly that they'd never even consider sitting like that in front of other people again. The urge boiled beneath his skin, pulsing together with the irritation squeezing his chest, but as absurd as it was, he couldn't make himself move. His muscles remained rigid, pinned to the couch as though something were preventing him from standing.
He dug his fingers into his palms until he felt his nails marking his skin, bit the inside of his cheek, and cursed himself for still being there.
By that hour, he should have already been in bed, asleep like he was every night. He had only come downstairs to refill his water bottle before returning to his room, but from the top of the staircase he'd spotted the two colorful heads far too close together. It was as though his feet had changed direction on their own. Before he realized it, he was already sitting on that couch, unable to look away from the scene unfolding before him, as though some invisible force compelled him to keep watching.
But that wasn't enough. The worst part was that Katsuki couldn't even explain why the scene bothered him so much. He couldn't find an answer that made any sense to justify why seeing Deku so damn close to Half-and-Half made his stomach twist like that.
Maybe it was because the two of them looked infuriatingly at ease, as though they were strong enough to forget about the rest of the world and waste hours talking about whatever nonsense came to mind.
Yeah, that had to be it. Who did those two think they were, acting so carefree? How could they be so relaxed knowing they still had so much room to improve?
Or maybe it was because Deku wouldn't stop rambling about battle tactics, sharing strategies, ideas, and observations with someone who, technically, was still a rival. What an idiot. How could someone be so stupid as to hand over the way he thought during a fight on a silver platter?
And above all, why did he never talk about those things with Katsuki? Why did he save that sparkle in his eyes and all that excitement specifically for that damned Half-and-Half?
Without realizing it, he became absorbed in watching every tiny movement between the two. Deku's legs, which had been folded on the couch, slowly slid down until they came to rest across Todoroki's lap. The distance between them shrank little by little, almost imperceptibly, as Izuku's toned calves settled comfortably over the other boy's thighs as though they belonged there.
Katsuki felt his chest tighten. Then his eyes rose once more to their faces, and he noticed that a few strands of Shoto's hair swayed slightly every time Deku spoke, a consequence of the absurdly small distance between them. A bitter taste instantly filled his mouth.
He kept watching the scene intently when he heard Todoroki invite Izuku to watch a movie in his room. The invitation came out casually, almost offhandedly, as if it were the most ordinary thing in the world, but there was something about that subtle smile on Half-and-Half's face that Katsuki couldn't decipher. That calm expression bothered him more than it should have.
Then his eyes landed on Deku.
The idiot's face twisted in surprise before turning a deep shade of red. The blush spread quickly across his cheeks, making even the scars scattered over his face seem more pronounced beneath the new flush. Izuku looked away for a moment, clearly embarrassed, and Katsuki knew.
Even before a single word was spoken, he was absolutely certain that the damn nerd was going to accept.
He felt a vein throb in his neck, hard enough to pulse beneath his skin. His throat tightened uncomfortably as an unpleasant shiver ran down his arms, making the hairs on the back of his neck stand on end.
The thought of Deku walking into that damn Half-and-Half's room was enough to make him clench his fists until his fingers ached. He didn't want to imagine the two of them alone behind a closed door. If they were already allowing themselves so much closeness, so many touches and lingering glances in front of the entire class, what would they do when no one was there to watch them?
The image forced its way into his mind before he could stop it, making his stomach churn in a way he refused to understand.
His tongue clicked against the roof of his mouth before he even realized it. The next instant, he shot to his feet in a sudden movement, far too quick to be considered natural. The force of it sent the couch sliding back a few inches, its legs scraping loudly across the floor—loud enough to draw the attention of much of the room. Mina stopped talking, Momo looked up from her magazine, and even Kaminari glanced away from his phone for a moment.
Unfortunately, the two boys on the couch seemed so focused on each other that they didn't even notice.
“Oi, you shitty Deku!” his voice cut through the room before Izuku could answer Todoroki's invitation.
For the first time that night, the emerald eyes completely left the half-and-half's face to settle on Katsuki. Only on him. Izuku's expression was a perfect blend of surprise and confusion, his brows slightly furrowed as he tried to understand the sudden interruption.
Katsuki needed to think of something. Anything. A reason convincing enough to stop Deku from spending the rest of the night with Todoroki. His brain worked desperately for a fraction of a second until the first plausible excuse came to mind.
“Uh... I need to talk to you. About the old hag.” He mentally cursed himself for answering too quickly.
He wanted to sound confident, like he had complete control of the situation. He puffed out his chest, lifted his chin, and narrowed his eyes at the two of them, trying to maintain a firm posture that was nowhere near the chaos raging inside him.
The truth was that he had no idea what he was doing.
Then Todoroki's gaze finally fell on him. It was a calm, almost bored look that traveled over Katsuki from head to toe without showing the slightest concern or annoyance. As if he posed no threat whatsoever. Then, slowly and naturally, Shoto raised one hand to Izuku's shoulder, resting it there with an infuriatingly casual calm, almost challenging.
He didn't say a single word, but to Katsuki, that gesture spoke for itself. It was as if the half-and-half were making it perfectly clear that he still had control of the situation and had no intention of giving up his place so easily.
Indignation washed over Katsuki in an instant. What the hell kind of move was that? How could that bastard do something so blatantly provocative while keeping the same serious, composed, and utterly indifferent expression? That was what irritated him the most.
Bakugo could always predict what people were feeling before they even opened their mouths, but when it came to Todoroki, he found nothing but a wall impossible to break through. There was no hesitation, nervousness, or any obvious emotion in those heterochromatic eyes. Only an unbearable calm that made his blood boil.
And, as simple as that touch on Deku's shoulder was, the gesture seemed to ignite something inside him. His chest burned, his jaw locked up again, and a suffocating heat spread throughout his entire body, far too intense to have been caused by such a small touch.
“Now” he insisted, his voice coming out firmer, low, and heavy with impatience.
Izuku didn't hesitate for even a second. He got up from the couch almost immediately, on pure instinct, moving completely away from Todoroki. The weight of the hand on his shoulder disappeared, and Katsuki felt the tension in his chest ease just enough for him to breathe again.
“Shoucchan, can we talk later?” Izuku asked, offering him one of those gentle smiles that seemed to come effortlessly.
Todoroki returned it in exactly the same way.
Okay.
What the fuck kind of nickname was that?
What the hell had that idiot Deku just said?
Katsuki felt his brain simply freeze for a moment. His eyes darted between the two of them, searching for any sign that this was some kind of terrible joke, but he found absolutely nothing.
Were they really that close? Close enough to come up with intimate nicknames for each other? When did that happen? How had he not noticed? Since when was there a ‘Shoucchan’? And more importantly, why did that single word make something inside him twist so violently?
His gaze returned to Todoroki. The half-and-half's expression remained exactly the same: calm, composed, almost lazy. There wasn't even the slightest trace of embarrassment or surprise at being called that. On the contrary. The ease with which he accepted the nickname made it obvious that he was completely used to it. As if hearing Izuku call him that was just another ordinary part of their usual routine.
That realization made Katsuki's irritation grow even stronger, spreading an unpleasant warmth through his chest. It was ridiculous. Irritatingly ridiculous.
Without saying another word, he turned his back before he could hear anything else between them. He completely ignored the curious looks from the extras scattered around the room stomping across the room, making a point of slamming his feet against the floor with every stride.
The sound echoed through the hallway, announcing his impatience long before any expression on his face could. His hands remained buried in his pants pockets, clenched into fists, while the water bottle stayed empty, completely forgotten ever since he'd decided to butt into that conversation.
Even so, he could hear Izuku's light footsteps right behind him, following without asking any questions.
The walk to Katsuki's dorm room was strangely silent. Neither of them seemed willing to break the silence that had settled between them, and with every step they took, the weight of the situation became more obvious. Izuku was probably trying to understand the urgency behind that sudden conversation, while Katsuki... Katsuki couldn't even understand himself.
Because the truth was simple, he genuinely had no idea why he was doing any of this.
Bakugo entered the room, turned on the light, and stepped aside to let Deku go in first. As soon as the other crossed the doorway, he pushed the door shut behind them.
His hand remained on the doorknob for a few seconds, motionless. His eyes stayed fixed on it as an idea crossed his mind. Would it be too weird if he locked it? The question felt ridiculous the moment it appeared, but before he could reconsider, he bit his tongue against his teeth and turned the lock with a sharp click that echoed through the silence of the room.
“Alright, Kacchan... What's wrong with Aunt Mitsuki? How can I help?” Izuku looked genuinely worried. His huge eyes remained fixed on Katsuki's, trying to find some hidden answer deep within them.
Under the room's white light, his green irises shone like two precious gemstones, vivid and impossible to ignore. His cheeks were still lightly flushed, perhaps because of the interrupted invitation, perhaps because of his sudden concern, making the freckles scattered across his face stand out even more against his fair skin.
Katsuki couldn't say when he'd started noticing those things. Much less when those lips had become so red, so glossy... so ridiculously inviting.
He looked away for a second, biting the inside of his own cheek hard enough to taste metal in his mouth. The air slipped slowly from between his lips in an almost inaudible sigh. His brain, which only minutes earlier had been working fast enough to come up with a convincing excuse, was now completely blank.
There was no sick aunt. There was no emergency. There was no reason at all for dragging Izuku out of the room. All that remained was the silence between them and the awful realization that he had absolutely no idea what he was supposed to say, or what he actually wanted to do next.
“What the hell was that with Half-and-Half downstairs?” Katsuki practically spat out the words, his tongue tripping over itself in his rush to get them out.
He felt his face heat up immediately and cursed himself for it. Great. On top of acting like a complete idiot, he was making it painfully obvious. He took a deep breath through his nose, trying to regain even the slightest bit of control, but the heat burning in his chest seemed to climb all the way to his ears, making it impossible to hide his irritation.
Izuku furrowed his brows slightly and wrinkled his nose, staring at him with such a genuinely confused expression that it almost made Katsuki question his own sanity. “What do you mean, Kacchan?”
His voice came out soft, carrying that irritating sweetness that seemed to caress Katsuki's eardrums instead of simply answering the question. There was genuine confusion in his large, attentive green eyes, as if he truly didn't understand the reason for that outburst. It didn't make sense. It couldn't.
“Deku, oh, fuck” he barked, taking a step forward without even realizing it. His eyes immediately met Izuku's, holding his gaze as his jaw locked up once again. “What the hell was that nickname? Are you going stupid now?”
Katsuki was a little desperate. No, he was very desperate.
The problem was that his brain seemed incapable of keeping up with the speed of his own mouth. The words simply slipped out before he could organize them, driven by an irritation that grew with every passing second.
As he waited for some kind of response, he watched Izuku's eyes take on a curious glint. The corners of his lips lifted into a small, almost imperceptible smile, and his head tilted gently to one side, exactly like a dog trying to understand a scolding without knowing what it had done wrong.
A strange pang shot through Katsuki's chest. What the hell was that now?
Izuku was playing dumb in the most idiotic way possible. Katsuki was almost certain of it. And yet, that confused expression, his slightly wrinkled nose, wide eyes, and innocent tilt of the head somehow managed to be, against all logic... cute.
He gritted his teeth. Katsuki wanted to kill him.
While Izuku searched his face with his eyes, clearly trying to find a logical explanation—or at least some clue as to what was going on—Katsuki remained silent. His gaze, however, never left the other's lips. They were pressed into a faint little pout, glistening under the bedroom light in a way he'd never noticed before.
It was strange. Ridiculously strange. Since when did he pay attention to Deku's mouth?
His eyes drifted downward before he realized it, stopping at the thighs covered by the ridiculous shorts Izuku insisted on wearing.
The image from just a few minutes earlier flooded his mind with irritating clarity. Todoroki's long fingers resting there so naturally. The closeness between the two of them. Izuku's body settled on that damned half-and-half's lap as if it were the most comfortable place in the world.
Katsuki had never gotten that close to those thighs. He'd never had the freedom to touch them like that. He'd never seen Deku relax that way beside him. And before he could stop the thought, he remembered those mismatched eyes following every movement of his full, red lips, lingering on them as if—
“Kacchan... are you jealous?” The question fell between them with almost absurd calm, completely interrupting the spiral of Katsuki's thoughts.
Bakugo bit his own lip before lifting his gaze. The moment his eyes met Izuku's, he was greeted by an unmistakably playful smile spread across his face, as though the whole situation were nothing more than a particularly amusing joke.
Izuku's lighthearted expression contrasted infuriatingly with the chaos raging inside Katsuki.
“Huh?! What?” he shot back, louder than he'd intended.
His voice came out thick with indignation, almost cracking at the end of the sentence. He could feel sweat slowly running down his temples as an uncomfortable heat spread across his face. The palms of his hands were damp, and tiny pops followed by sparks escaped involuntarily from his fingertips, briefly lighting up the room. The air around him seemed to vibrate along with his irritation, betraying a nervousness he would have done anything to hide.
“Yeah, Kacchan! Is that jealousy?” Izuku pressed, unable to hold back the smile that grew wider with every word. There was an amused sparkle in his eyes, as if he were genuinely entertained by the blond's reaction. “Kacchan, you're such a dummy! You'll always be Kacchan, even if Todoroki-kun is Shoucchan!”
“Shut up! Don't say that here!” Katsuki growled.
He wouldn't have been able to explain why, not even with a gun to his head, but hearing that nickname roll so naturally, so lightly, so casually off Izuku's lips... stirred something violently inside his chest. It was as if every time "Shoucchan" was spoken, his patience wore a little thinner.
The thought that the name had already become part of the two of them's everyday routine, that Izuku said it in such a spontaneous, affectionate way, was unbearable. Katsuki clenched his teeth so hard that his jaw started to ache.
At that moment, he didn't know which of the two he wanted to kill more.
“So, Kacchan...” Izuku began, unable to hide his smile. He took a step forward, closing the distance between them. “You lied to me, saying Aunt Mitsuki wasn't feeling well, just to get me away from Todoroki? Were you really that jealous, Kacchan?”
That was a provocation—the most irritating kind.
Katsuki was certain that this was exactly what Deku had wanted from the very beginning: to get under his skin, make him completely lose his head, and admit something that even he himself couldn't understand. The worst part was that it was working. That smug smile, the calm voice, and those eyes gleaming with amusement only seemed to feed the fire burning inside his chest.
“Fuck you. Stop saying bullshit like that! Jealous my ass!” he growled through gritted teeth, feeling his jaw throb from clenching it so hard.
Now, maybe there were only three steps between them, or four. Katsuki wasn't even sure anymore.
The only thing he could focus on was Izuku's face getting closer and closer, filling his field of vision, while that damned smile stubbornly stayed exactly where it was.
“I wanna know what exactly you two were doing!” The question came out louder than he intended, driven by an urgency that even he didn't understand. It sounded less like an accusation and more like a desperate demand for an answer that would settle the turmoil inside his head.
Izuku tilted his head slightly to the side again. His smile faded a little, giving way to a more thoughtful expression. It was as if, for the first time since entering that room, he was starting to connect the dots and understand what was really happening in front of him.
Katsuki couldn't stand that pause.
“Don't play dumb, idiot!” He took another step forward, closing the distance between them even more. “I saw it, Deku. I saw him putting his hand on you... and... argh!”
The words died in his throat. How was he supposed to explain it?
How could he put into words what bothered him so much?
He frowned, running one hand impatiently through his hair before looking back at Izuku. “That... closeness.”
The last word came out almost as a mutter, heavy with frustration. It was ridiculous. So ridiculous that he could hardly believe he was arguing over something like that.
Izuku broke into a huge smile. He clapped his hands together right in front of his chest in a spontaneous gesture that seemed to light up his entire face, then took two steps forward without the slightest hesitation.
The distance between them had almost completely vanished. Only a single step remained before their bodies would truly be close.
“Kacchan... are you upset?”
The question came out playful, but so gentle that Katsuki’s stomach tightened.Hearing that word leave Izuku's rosy lips, accompanied by that curious gaze and that unbearably kind smile, was the final straw.
Sweat was already trickling discreetly down his temples despite the pleasantly cool room. His heart was pounding far too fast, his hands remained damp, and he simply couldn't understand what he was feeling—much less come up with an answer that made any sense.
“Deku... do you wanna die, you fucker?”
The threat came automatically, out of pure reflex. Katsuki instinctively raised his hands, taking a defensive stance that didn’t match his aggressive tone at all. It was as though his body was prepared for any sudden movement while his mind remained completely lost.
Izuku didn't seem intimidated for even a second. Quite the opposite. The smile on his face merely lost a bit of its teasing edge, becoming softer, more patient, while his green eyes stayed fixed on Katsuki, attentive to every tiny reaction. There was no fear, hesitation, or discomfort in his posture. Only an irritating calmness, as if he knew that behind all that aggression lay something Katsuki still couldn't put into words.
“Kacchan... you're the one who brought me to your room. If you want me to leave, all you have to do is say so.”
Those words hit him harder than any explosion ever could. Katsuki remained frozen, staring at Izuku as the sentence echoed over and over inside his head.
Because Deku was right. He was the one who had come up with that completely ridiculous excuse about Mitsuki just to pull him away from Todoroki.
He was the one who had crossed the room without looking back, expecting Izuku to follow.
He was the one who had opened the bedroom door, waited for the other boy to step inside, and then, on an impulse that still made no sense, locked it behind them. Every bit of it had been his doing. No one had forced him to do any of it.
The solution was right there in front of him. All he had to do was say the conversation was over. All he had to do was unlock the door, step aside, and tell Deku to leave. It was simple. Ridiculously simple. Anyone else would have done exactly that. They would have ended the pointless discussion and gone on with the rest of their night, pretending none of this had ever happened.
But Katsuki remained rooted to the spot.
His eyes locked on Izuku.
His hands still tense at his sides.
His chest tight in a strange, unfamiliar way.
Because no matter how hard he tried to convince himself it was nothing more than irritation, something inside him completely rejected that solution. The thought of opening the door and watching Deku walk through it to return to Todoroki's room made his stomach twist again.
He didn't want Izuku to leave.
At least... not yet.
Izuku took Katsuki's silence as confirmation of everything he had suspected since stepping into that room.
A pleasant chill ran through his stomach, mixed with an anxiety that was difficult to control. He was apprehensive about where this conversation might lead, but at the same time, a quiet excitement warmed his chest.
Maybe this was the opportunity he had been waiting for all this time. The perfect chance to confront Katsuki about the feelings he had kept hidden for years, without running away, without explosions, and without either of them changing the subject at the last moment.
“Kacchan...” Your tone was different this time. Lower, gentler, almost like a call.
The simple way he said that nickname made Katsuki's head throb. His gaze automatically met the green eyes in front of him, noticing they were no longer wide with confusion. There was an unusual calm in them, accompanied by a quiet determination the blond had never seen before.
Izuku took another small step forward. The height difference between them became even more obvious. Katsuki had grown a lot over the past few years, while Izuku had remained only a few centimeters shorter, forcing him to tilt his face up slightly to maintain their eye contact. In response, Katsuki lowered his head almost instinctively, closing the distance between them even more.
Now they were close enough to notice every detail about each other, from their uneven breathing to the smallest shifts in their expressions.
“Kacchan... do you want to be my one and only?” The question came out slowly, each word spoken with care as Izuku's pink lips moved just inches from his face. “Do you want to be the only one I give cool nicknames to?”
Katsuki swallowed hard. The unexpected closeness made his throat tighten, and he felt Izuku's warm breath lightly brush against his neck. His heart seemed to skip a beat as every thought he had been trying to put together vanished all at once.
“What the hell are you talking about, Deku?” he muttered, letting out a short sigh. His voice no longer carried the same firmness as before. There was more confusion than anger in it. He genuinely couldn't understand where Izuku was going with this.
Without asking for permission, Izuku slowly raised his hands and rested them on Katsuki's shoulders. The touch was light, almost hesitant, but enough to make the blond's entire body stiffen.
A shiver ran down the back of his neck, and for a brief moment, he thought about stepping away. He couldn't. His feet remained rooted to the ground while his eyes stayed fixed on Izuku's face, unable to look anywhere else.
“Do you want to be the only one who's allowed to touch me, Kacchan?”
What kind of question was that? And who the hell did that damn Deku think he was to talk like that? As if Katsuki actually wanted to... touch him. No. Not even close.
Katsuki didn't care about some idiot nerd who rambled nonstop, didn't care who those green eyes looked at with such brightness, or who could make him smile, much less who touched those pink lips, caressed his strong thighs, or held those warm, rough hands. Damn it. He didn't care about any of that.
Deku's hands were still resting on his shoulders. The warmth seeped effortlessly through the fabric of his T-shirt, spreading slowly across his skin until it tingled. It was a firm yet gentle touch, present without being invasive.
Warm enough that, for one brief second, Katsuki entertained the completely absurd idea that Izuku was using some new aspect of his Quirk to warm him up. The thought was ridiculous. Even so, it seemed easier to believe that than to admit that a simple touch was enough to leave him so utterly shaken.
“Deku...” His name slipped from his lips almost without him realizing it. It came out low, husky, barely above a whisper, carrying far less irritation than either of them would have expected to hear.
Instinctively, his body reacted before his mind could stop it. He took another small step forward, finally closing the distance between them. The movement made Izuku's arms naturally slide over his broad shoulders until they came to rest around his neck. His slightly crooked fingers met behind his nape, forming a loose embrace that, somehow, seemed to fit perfectly.
Katsuki remained still for a moment, trying to understand why his heart was beating so fast. “I wanna touch you...”
The words came out in an almost involuntary sigh. They sounded like a confession torn from him by force, something he hadn't even known he was ready to admit. The strange feeling that had been building in his chest ever since he'd come downstairs had finally found a way to escape, even if he himself didn't fully understand what it meant.
Izuku didn't look away.
His smile became small, calm, almost affectionate. “Then touch me, Kacchan.”
It sounded like an order, and even though Katsuki had always hated being told what to do, he decided to obey this one in particular.
His hands trembled faintly as they stopped hanging stiffly at his sides and slowly moved forward, as though they were afraid of breaking that moment. His fingers found Izuku's surprisingly slim waist over the white T-shirt. Even through the fabric, the warmth of his skin was unmistakable.
The moment his palms settled there, he felt the green-haired boy's abdominal muscles tighten beneath his touch, and that simple movement was enough to make his breath catch for a brief second.
At first, the touch was gentle. Katsuki kept his hands on Izuku's waist without truly squeezing, as though he was still trying to figure out how far he was allowed to go. His eyes remained fixed on the emerald ones before him, watching with restless curiosity the tenderness that lingered there.
There was no teasing in Izuku's gaze at that moment, only a softness Katsuki had never really known how to handle. It was strange to realize that Deku was so close, so calm, and yet showed no intention of pulling away.
Then Izuku moved one of his hands. His fingers slowly slid over Katsuki's nape, gently stroking the short strands of his hair in a light, almost absentminded gesture. The effect was immediate. A shiver ran through Katsuki's entire body from head to toe, making his muscles tense before he could control them. Instinctively, his fingers tightened around Izuku's waist, pulling him a little closer as warmth quickly rose up his neck.
Izuku moaned.
Fuck.
Deku had moaned for him.
The sound was soft, muffled, slipping between his pink lips in a short sigh that would probably have gone unnoticed by anyone else.
To Katsuki, however, it seemed far too loud. His heart instantly raced, his cheeks grew even hotter, and his hands became damp with nerves. He stayed frozen for a second, staring at Izuku from far too close, feeling his warm breath brush against his skin as he futilely tried to regain control of his own body.
Katsuki should have stepped away. He should have shoved that nerd away, told him to get out of his room, and pretended none of this had ever happened. He should never have looked at that damned face again, dusted with freckles that were far too pretty and lit by those vibrant green eyes that seemed to see right through him. That was what would have made sense.
But he didn't.
Instead, his fingers tightened just a little more around Izuku's waist, pulling him closer until the distance between them disappeared completely. Their hips brushed lightly together in an accidental touch, but Katsuki didn't pull away.
Quite the opposite.
There was something desperate in that gesture, a need for closeness that he didn't even know how to name.
Izuku noticed.
Katsuki saw it happen in his eyes before either of them made another move.
A faint smile returned to the green-haired boy's lips, small and almost imperceptible, as he slowly rose onto the tips of his toes to lessen the height difference between them.
The movement was calm, then, Izuku's lips found his chin.
The kiss was brief, gentle, almost innocent. A delicate touch that lasted only a moment, yet it seemed enough to make Katsuki's heart skip an entire beat. The warmth of that contact lingered on his skin even after Izuku pulled back by just a few inches, and for a moment, Katsuki simply stared at him, unable to gather a single coherent thought.
He no longer had any idea how far this situation had gone.
Much less how they had ended up here.
He only knew that, somehow, Deku's mouth was far too close. And thinking stopped being an option. Driven by an impulse he couldn't restrain, Katsuki lowered his head a little more and pressed his lips against Izuku's.
It was a hesitant kiss. Brief. Almost a question.
Even so, the instant their lips met, Katsuki felt the world around him disappear for a few seconds. Izuku's lips were soft—far softer than he had ever imagined possible—and the simple contact sent a shiver through his entire body.
It was strange, but at the same time, it felt oddly natural, as though some part of him had always known exactly where it wanted to be from the very beginning of that night.
When the kiss ended, he didn't pull away immediately. He stayed there, breathing only inches from Izuku, trying to understand why a single impulse had been enough to turn his entire world upside down.
Izuku felt his heart race so wildly that he could barely keep up with it. This had to be a dream. Kacchan had just kissed him.
His green eyes immediately lit up, filled with a mixture of surprise, curiosity, and a silent longing for that moment not to end. For so many years, he had imagined countless possibilities for the feelings he had kept hidden, but none of them came close to the reality unfolding before his eyes.
And then, before he could think too much about it, he simply acted.
Taking advantage of the fact that his arms were still resting around Katsuki's neck, he gently pulled him closer. He rose onto the tips of his toes once more, closing the height difference between them, and met the blond's lips again.
He felt Kacchan's hands tighten subtly around his waist while the sweat on his palms dampened the white fabric of his T-shirt. He didn't care for even a second. In fact, it only made everything feel more real, more tangible, as though he could finally feel that Katsuki was nervous too.
Katsuki's larger body radiated warmth. Having him so close made Izuku notice details he had never imagined he would: the firmness of his arms, the steady touch of his hands, the slightly quickened breath brushing against his face.
His lips were different from what Izuku had dreamed of for years; Thin, soft, and surprisingly gentle, they carried a hesitation that contrasted with Katsuki's explosive demeanor.
It was so much better than any fantasy Izuku had ever allowed himself to build, not even in his deepest dreams had he believed that Kacchan would one day kiss him like that.
Without wanting to interrupt that moment, he moved a little closer, allowing the kiss to linger naturally. What had begun as nothing more than a brief touch became something longer, warmer, though it still carried the uncertainty typical of people experiencing that moment for the first time.
There were small missteps, shy pauses, and subtle smiles slipping through between breaths, but none of that diminished the intensity of what they felt. On the contrary, it made everything more genuine.
Katsuki could no longer organize a single coherent thought. His heart seemed to be beating far too fast, his chest rising and falling in an uneven rhythm, and his mind simply stopped working. All that remained was the feeling of Izuku so close, the warmth of his body, and the certainty—more impossible to ignore with every passing second—that there was no longer any room to pretend this meant less than it truly did.
Their tongues met hesitantly at first, as though they were still trying to understand their own rhythm, until little by little they found a more natural, almost instinctive harmony.
There was a strange familiarity in that movement, something that resembled the way they had always fought side by side, anticipating each other's weight and intentions without needing words. Now, however, everything was different—slower, more disorganized—as though every second was being discovered for the very first time.
Their breathing blended together unevenly, out of sync, breaking the silence of the room with soft, interrupted sighs.
Katsuki no longer had any control over his own rhythm, feeling completely undone, lost in the contact that demanded every ounce of his attention. Izuku didn't seem much different; if anything, there was something even more intense about him, more surrendered, as though he were allowing himself to feel everything without a single barrier.
Katsuki could feel Izuku's smaller body pressed more clearly against his own, firm enough to keep him close yet still light in a way that was almost unsettling. Izuku's tongue was warm, curious, daring in the small movements that made Katsuki's stomach churn in a way he couldn't put into words.
Agrowing warmth spread through his chest, racing too quickly to ignore, leaving him even tenser and, at the same time, unable to pull away. The deeper the kiss became, the more he felt there was no turning back, not because he couldn't stop, but because, in that moment, he didn't want to.
Katsuki threw all restraint aside when he felt his cock growing heavy inside his briefs, and Izuku's hips pressed him against his own body. The kiss broke, and both of them let out a low moan, a sound meant only for the two boys in the room.
Izuku knew Kacchan was well-endowed—he had noticed during class before—but nothing compared to the overwhelming reality of being this close, a closeness that made his thoughts falter for a moment. He swallowed hard, feeling heat rush to his face as he tried to hold on to some shred of rationality, failing miserably. He could feel it against his thigh, nearly reaching his knee. It was huge. His mouth watered.
They looked at each other for a brief moment, the tension between them heavier than any words could ever be, until Katsuki seemed to lose patience with his own hesitation. With one firm movement, he pushed Izuku onto the bed, positioning himself over him with the ease of someone who had already decided what he wanted from the very beginning. He settled between the nerd's legs, while Izuku welcomed him readily, his thick thighs spread apart.
Izuku lay there, trapped between the mattress and Katsuki's commanding presence, feeling his heart pound too hard to ignore. Katsuki leaned his face close to his before moving away, trailing slower, lingering kisses down his neck that gradually unraveled Izuku's train of thought until everything was reduced to the feeling of their closeness, their warmth, and the uneven rhythm of their breathing.
The blond boy didn't exactly know what he was doing. He had never put himself in a situation like this before, and everything seemed both intense and too disorganized to be rationalized. It was as if each thought came in fragments, blurred by the proximity and the weight of something too new to clearly name. Still, there was a persistent, almost irritating need to remain there, not to move away.
It didn't make sense the way Katsuki was used to dealing with things. It was strange, even uncomfortable, to realize that his presence wasn't just familiar, it was magnetic in a way he couldn't simply ignore or put into words.
There was something about wanting Deku, about wanting more of him, that made him restless, as if he were constantly one step out of control. And that, for someone like Katsuki, was the most irritating part of all.
“Ka-cchan~” Deku groaned again.
Katsuki's ears burned with a mixture of shame and indescribable excitement, a conflict that only made him more angry with himself for not being able to simply ignore it. He didn't know exactly what he was doing; there was no manual or logic behind it, but there was still a persistent feeling that this was right, or at least too right to be interrupted.
Izuku's gaze below him only reinforced this, as if pulling him further into the situation effortlessly.
Izuku's lips were slightly parted, tense as if trying to hold back any more obvious reaction, his eyes half-closed and filled with something Katsuki couldn't fully decipher, but which made him strangely attentive to every detail. His hands found support on Katsuki's chest, firm enough not to let him forget that this was real, that it wasn't just another provocation or a fight between the two, but something different, something unstable.
And yet, there was nothing familiar about it. There was no comfort in the way it was happening, nor in the way they touched or looked at each other. There was no familiarity in kissing someone for the first time, much less when that someone was Izuku, and that made everything even more confusing than Katsuki wanted to admit.
Impatient, he forcefully pulled his own shirt up, as if angry at the fabric that held him back, revealing his chest marked by training and battles.
The movement was abrupt, almost aggressive, fueled by a haste he couldn't control. Izuku watched everything, his eyes sweeping over every detail with an almost reverent attention, as if he were seeing something he had never been allowed to observe so closely.
The war scar was still there, piercing his skin in a striking way, unlike anything around it. Izuku had never been so close to it, never faced it with such clarity.
There was something within him that wanted to touch, to understand, almost instinctively, not just admire, but acknowledge. His eyes shone for a moment, fixed on that vision, before Katsuki's urgency shattered any space for contemplation.
Kacchan took Izuku's lips again, more firmly, more confidently, as if he were losing patience with any remaining hesitation between them. His hands found his waist naturally, pulling him closer until there was no space left between them.
Izuku responded almost immediately, with no intention of resisting, his fingers entwining in the blond strands with a tenderness that contrasted sharply with the intensity of the moment, holding Katsuki as if it were the only point of stability left.
Everything seemed too new, too strange, a mixture of heat and confusion that made Izuku's body react even before he could understand what he was feeling. There was something burning inside, a growing and disorganized sensation that left him breathless for moments too short to ignore.
Katsuki, on the other hand, was not naive. He knew exactly what this was becoming, he was aware of the path they were following and the point where they would inevitably arrive if neither of them interrupted. Still, there was a kind of raw care in the way he tried to conduct everything, as if he were balancing impulse and responsibility at the same time.
With one hand, he untied his own sweatpants, loosening the lycra at the waist, but didn't take the pants off. He adjusted his member so that it was pointing upwards, trying to loosen the tightness without startling Izuku. The blond, while playing with Deku's full lips, moved his hand to his groin, searching for the nerd's erection, so he could help him too.
He found nothing, or rather, he didn't find what he expected, and this made him hesitate for a moment too short to be comfortable.
Katsuki arched his eyebrows slightly and ended up pulling away from Izuku's lips, still close enough to feel his uneven breathing. The sound Izuku let out in protest hung in the air between them, laden with frustration and need, as if any interruption would be unbearable at that moment.
Izuku was completely out of sorts. His face flushed, his hair disheveled from constant contact, his expression too open for someone who normally tried to control himself all the time. There was something about him in that state that held Katsuki's attention in an almost irritating way, not because of the disarray itself, but because of the contrast between it and everything Izuku usually was.
He seemed vulnerable, exposed in a rare way, and yet… beautiful. Beautiful enough to make Katsuki linger a second longer than he should, staring.
“Deku… ” Katsuki called, his voice coming out lower than he intended, completely breathless, his breathing still disordered from the proximity. He swallowed hard, trying to regain some control over himself before speaking again. “Where… where is your dick?”
The question came out harsher than he wanted, but still carried an evident hesitation, as if he himself wasn't sure what he was asking or what he expected to hear in response.
Izuku, on the other hand, froze for a second. His face immediately flushed even more, his cheeks turning intensely red as he instinctively hid part of his expression in his hands, clearly overcome with embarrassment. The contrast between the intensity of the moment and how small he suddenly seemed made Katsuki's chest tighten strangely.
“I... I don't have one…” he replied softly, almost in a whisper, his voice trembling slightly with shyness. Then, as if insecurity finally overflowed, he looked up again, staring at Katsuki with large, moist eyes. “Do you want to stop, Kacchan?”
The doubt in his voice was enough to make Katsuki freeze for a moment.
“I'm sorry, Kacchan, I didn't mean to confuse you, I don't want you to stop” Izuku continued quickly, stumbling over his own words, clearly panicked at the possibility of having crossed some line. “I just... I want to get closer to you. I want to continue like this. I want you.”
The last sentence came out shorter, more sincere, as if he hadn't been able to hold it in any longer.
Katsuki understood what it was. And that, somehow, only made everything heavier in his chest.
He couldn't just stay angry. Not this time. Because there was something in Izuku's gaze, in the way he spoke, that didn't come from provocation or joking. It came from something else. From an entire history that Katsuki knew all too well, even if he avoided confronting it.
The bullying, the rejection, the way Deku always seemed to expect to be pushed away at any moment. Damn it. He had been a jerk for so long that he might have taught Izuku to expect pain even when it didn't exist.
The awareness of this made his stomach clench uncomfortably.
And yet, he didn't want to stop.
Katsuki's whole body was tense, hot, as if he were still trapped in that moment, unable to find a way out. Izuku's closeness, the way he looked at him, all of it seemed to continue reverberating within him in a way he couldn't quite name. He only knew he didn't want distance. He didn't want it to end there.
But then he saw Izuku better.
His face still flushed, his eyes shining moistly, the insecurity evident in every small gesture that tried to hide what he felt. That hit Katsuki in a different way, deeper than any previous provocation or confusion. A knot immediately formed in his throat, tight enough to make him hesitate for the first time in that entire sequence of impulses.
“Do you really wanna do this?” Katsuki asked, and for the first time his voice came out lower, more restrained. He brought his hands to Izuku's face, holding it firmly enough to keep him there, but still with an almost imperceptible hesitation, while their noses touched and the distance between them disappeared completely.
Izuku smiled.
A small, but intense smile, his teeth slightly peeking out between his lips and pushing his cheeks against his emerald eyes, made his expression even more open, even more sincere. The scars on his face seemed softer at that moment, as if they had lost some of the weight they normally carried.
Eithout any hurry, his arms returned to wrap around Katsuki's shoulders, seeking that contact naturally, as if it already belonged to him. One of his hands moved up to the blond strands, sliding through them with an almost distracted delicacy, while his legs adjusted Katsuki's hips to bring him closer, reducing the space between them until only the shared warmth remained.
“More than anything else, Kacchan.” The answer came firmly, without hesitation.
And that was enough.
The kiss returned as if it had never truly ended. Deeper now, more confident, laden with a familiarity that didn't come from chance, but from years of something that had always existed between them without ever having been spoken aloud.
Katsuki didn't back down. On the contrary. He responded with the same intensity, as if he had finally stopped fighting against something that had always been there. Huffed between kisses, impatient with the amount of fabric surrounding them, stifling them.
The fabric of Izuku's shorts was flexible, simple gym shorts. One of his large hands went to the waistband of the garment, pushing his body away so that he could, carelessly, pull it down.
Izuku understood the message, raised his hips, holding Kacchan's face close to his, as if he depended on proximity to survive, as if Kacchan were his lifeblood. He felt the cold hit his buttocks and let out a muffled moan against the blond's warm lips when the fervent hand adjusted to his bare waist and placed a considerable squeeze on his pale skin.
Izuku tapped his feet and finished taking off his shorts, impatient. Katsuki settled back between his legs and Porra.
He felt, through the head of his penis, the only thing exposed on his body: Deku's underwear. He hadn't seen it yet, didn't know what it was like, but thought it was made of a rough fabric, and for some reason, it was wet. He raised an eyebrow and ended the kiss with the boy below him.
Curious, Katsuki moved slightly away from the smaller body, tilting his gaze as if he wanted to understand exactly what was hidden under Izuku's clothes at that moment. The movement was quick, but not without attention, as if he himself were trying to organize the whirlwind of thoughts that still didn't make sense in his head.
Izuku immediately noticed the change and reacted almost instinctively, pulling his own shirt down in an attempt to cover himself, clearly overcome with embarrassment.
The gesture betrayed how new this was for him too, the same silent uncertainty of someone who had never gone this far, and who was still trying to understand how far it was safe to go.
Katsuki snorted softly at Izuku's attempt to hide, not exactly annoyed, but uneasy with the hesitation that broke the rhythm between them. Without thinking much, he brought his hands to the hem of the green-haired boy's shirt, firmly stopping the movement. His fingers were larger, firmer, but the touch wasn't rough as one might expect; there was a strange mixture of strength and care, something almost contradictory, as if he were trying to maintain control without scaring him.
Izuku stood motionless for a moment, surprised by this attitude coming from Kacchan, something he would never have associated with how Katsuki usually acted.
Katsuki was speechless at what he saw before him, completely taken by surprise by the detail that was now revealed without any kind of barrier.
His eyes slowly descended, finding a small, delicate piece of black lace fabric, with a subtle transparency that made it clear how light it was. Floral patterns were woven into the lace, almost as if hand-made, and small, discreetly shimmering stones decorated the waistband, softly reflecting the light.
The fabric lightly accentuated Izuku's hips, fitting perfectly, while his thighs, freckled in shades of brown and orange, contrasted sharply with the black of the garment and his fair, greenish skin, making the ensemble even more striking and difficult to ignore.
Katsuki's fingers trembled slightly, betraying how unannounced he had been struck by it. For a moment, he was completely speechless, caught between surprise and the inability to look away. Izuku, in turn, felt his face flush with embarrassment, his cheeks turning so red that it seemed impossible to hide anything in that state.
“Do you wear this kind of thing every day, nerd?”
“Yes, Kacchan…” Izuku replied in a breath, inhaling deeply, unable to hide the embarrassment etched on his face.
Katsuki bit the inside of his cheek.
The answer, however simple, completely scrambled his thoughts. The idea of Izuku wearing that kind of clothing every day made him strangely uneasy.
How many times had they trained together? How many fights had they had, how many arguments had ended in shoves, explosions, and provocations? And, all this time, Deku wore something so delicate under his uniform, something Katsuki would never have imagined. The image seemed incompatible with all the memories he had of him, and yet, it made absurd sense now that it was before his eyes.
Fuck.
Just thinking that it had always been there, hidden under the baggy clothes and training uniforms, Katsuki felt his head throb again. It was ridiculous how much that detail, seemingly so small, had managed to destabilize him. He took a deep breath, trying to organize his thoughts, but it was useless.
The more he stared at Izuku, the more he felt he had discovered a side of him he never even imagined existed, and that, for some reason, was driving him to the brink of madness.
Slowly, Katsuki moved his fingers to the fabric, caressing Deku's hips over his underwear, feeling the sensation vibrate. He ran his fingertips over the sculpted designs, feeling the rough fabric itch his fingers. He slowly lowered his right hand while his left continued to hold Deku in place, as if he were about to get up and run away at any moment. Katsuki didn't want him to do that.
His daring and curious fingers slid over the wet part of the underwear. Izuku felt his body tremble and his breath catch as the blond boy moved down, touching delicately.
“Is it normal to be this wet?” There was a small pout on his lips, his eyebrows slightly arched in an expression of concentration that Izuku knew well. Slowly, Bakugo raised his gaze until it met the green-haired boy's face.
Deku remained completely red, his mouth slightly open as he gripped the hem of his shirt so tightly that his knuckles were white. The shame etched on his face was almost palpable, yet he didn't take his eyes off Kacchan for a single instant.
Izuku thought he understood what was happening. Kacchan had never seemed like the type of person to seek references or waste time watching pornography, or anything like that, so it made sense that he was dealing with this situation completely on the fly.
Perhaps, if the situation were different, if it were a penis, he would try to reproduce something he knew from experience, relying only on instinct. But, for Katsuki, this was uncharted territory. It was unlike anything he had probably imagined, and the almost stubborn concentration etched on his face betrayed how much he was trying to understand, alone, how to act from then on.
“Hmm, yes, Kacchan” He lifted his body, supporting himself on his elbows to get a better look at what Katsuki was doing “I want… I want you, I really want you. That's why it is so… wet.”
Izuku bit his lower lip, carefully observing Katsuki's concentrated expression, hoping he could understand what he meant without him having to explain it aloud.
Well, he understood.
Partially.
This was completely different from anything he knew. Katsuki had never had to think about something like this; the only reference he had were the old elementary school biology books, with cold diagrams and illustrations that bore no resemblance to the reality he now had before his eyes.
There was no experience to guide him, only his own curiosity and the stubborn determination he had always carried with him.
Bakugo nodded discreetly, clenching his jaw tightly. If he continued to hesitate, the two would remain standing in that same place forever. He took a deep breath, trying to ignore the anxiety tightening his chest, and decided to trust the little he knew.
Still over the fabric, his fingers slid slowly, cautiously exploring the most sensitive area—which he assumed to be the clitoris, vaguely remembering that it was the part with the highest concentration of nerve endings. He pressed gently, increasing the force only enough to observe any change in Izuku's expression. His goal was to understand his reactions before advancing, discovering that unknown territory little by little, as if each small movement taught him something new.
With each touch, Izuku felt his own heart tremble in his chest. His breathing became increasingly irregular, while the heat slowly spread through his body, making his legs tremble slightly. Until then, he had only known his own touch, his own movements, and the rhythm he had learned on his own.
Feeling Katsuki there, discovering him with the same insecurity he himself felt, transformed everything into something completely different from what he was used to.
Izuku couldn't decipher what was happening behind the ruby eyes in front of him. Katsuki's curious and focused gaze seemed to absorb his every little reaction, while a drop of sweat slowly trickled down his forehead, disappearing along the contours of his face.
Deku followed that short path for a moment, wondering what the blond's next move would be, unable to predict any of his actions. It was precisely this uncertainty, combined with Kacchan's unexpected care, that made his heart beat even faster.
Izuku's heart skipped a beat as the panties were gently pushed aside, allowing the cool air to reach his intimate area. A shiver ran through his entire body. There was no turning back. For the first time, he was completely exposed before Kacchan, and the shame made his cheeks burn even more as his fingers instinctively closed on the fabric of his own shirt.
Katsuki's mouth opened slightly, taken aback by the sight before him. The tightness in his chest increased, and his breathing became heavier as the hand that had been resting on Izuku's waist slowly descended, hesitating for a brief moment before reaching his intimate area. His eyes scanned every detail with an almost reverent curiosity, trying to comprehend something he had never had the opportunity to experience so closely. The delicate skin, the contrast of tones, the few carefully trimmed dark green hairs... everything seemed too new to him.
A soft, characteristic perfume reached his nostrils, making Katsuki hold his breath for a second. Unable to suppress a small gasp of disbelief, he immediately remembered an old conversation with Kirishima. At the time, he had thought it was an exaggeration when his friend commented that someone could go "crazy for pussy."
Now, staring at Izuku from that ridiculously small distance, Katsuki finally understood what he meant. He had the distinct feeling that he could very well go crazy right there, if Deku allowed it.
He wanted to explore. He wanted to feel the texture, discover what it was like to the touch, understand every detail of this novelty.
His thick, calloused finger slowly returned to the already sensitive clitoris and, carefully, slid down, reaching the entrance of the vagina. It was completely wet. A liquid unlike anything Katsuki had ever felt covered his fingers; it was thick, viscous, almost like a thin layer of honey.
“Deku, shit... what the hell is this?” he asked, completely intrigued. He didn't remember any of this from elementary school Biology class.
He slowly brought his fingers to his nose, inhaling curiously while keeping his eyes locked on Izuku's. Up close, the aroma was soft and completely different from what he had imagined. It was warm, delicate, laden with something he couldn't describe in words, but which made his heart race even faster.
Without much thought, he brought his fingers to his lips, tasting the aroma with the same curiosity that had guided him from the beginning. The sensation was unexpected, unlike anything he had ever known, and he remained silent for a few seconds, trying to process this discovery.
Meanwhile, his eyes met Izuku's again, as if searching for some answer to the whirlwind of thoughts that filled his head.
Izuku shook his head, a blush spreading across his cheeks once more. He lifted his body slightly, closing the distance between them until his breath met Katsuki's face. Slowly, he brought his hands to the waistband of the blond's sweatpants, in a silent request for them to be removed. Kacchan understood immediately. In a few seconds, the pants were already on the floor, followed by the dark underwear.
Izuku was amazed. The abrupt movement made Katsuki's body tense, and his penis lightly bumped against his own abdomen. It was even bigger than Izuku had imagined. His eyes scanned every detail with an almost innocent curiosity. The blond hairs descended from his navel to the base of his cock, carefully trimmed, while the rest contrasted discreetly with his skin tone. The most evident veins ran along its entire length, and the pink glans seemed perfectly defined. At that moment, Izuku had the impression that Kacchan managed to be absurdly beautiful in absolutely everything.
Katsuki silently watched the glint that appeared in Izuku's emerald eyes as he realized Izuku was staring at him like that. Perhaps he should feel ashamed for being so completely exposed before him. Perhaps he should want to hide his own body or look away. But he couldn't. Quite the opposite.
There was something in Deku's admiring expression that warmed his chest in a strange way, making any embarrassment disappear before it even arose.
Without taking his eyes off the green-haired boy, Katsuki brought one hand to his face and gently held his chin, firm enough to make him lift his head and meet his gaze again.
“Much better than that damn half-and-half's, isn't it, Deku?” he asked in a low tone, heavy with provocation and a jealousy he no longer bothered to hide.
As he said this, he moved closer once more, closing the distance between them until their foreheads touched. With a slow movement, he guided Izuku backward, causing him to fall onto the mattress, without Katsuki taking his eyes off him for a single instant.
“What? What do you mean?” Izuku seemed genuinely confused. He pouted slightly as he stared into the ruby eyes that seemed to pierce his soul. “I never... I never did anything like that with Todoroki-kun…”
“You lying nerd! You two were so... damn, so close! Don't lie to me, you damn Deku!"”
Katsuki's indignation overflowed in every word. His fingers still held Izuku's face firmly, but there was a strange care hidden behind the strength, as if he himself didn't realize he was being more delicate than he wanted to admit. His red eyes burned with jealousy, unable to hide how much that scene in the room continued to hammer in his head. He replayed, over and over again, Todoroki touching Izuku, the two of them smiling, the nicknames, the closeness... It was eating him up inside.
Izuku felt his heart race at that reaction. Even completely red with embarrassment, he couldn't help a small smile that threatened to appear at the corner of his lips. He could feel a trickle of lubricant running from his vagina, down his buttocks, his pussy tightening around nothing.
Katsuki was still there, consumed by that childish jealousy, arguing as if he truly believed something had happened between him and Todoroki. It was almost unbelievable when his penis was so close to his vulva, so close he could feel the heat emanating. “Kacchan... I would never do that with anyone other than you.”
The sentence came out low, but firm; it was the purest truth.
Throughout all that time, opportunities had never been lacking. There were lingering glances, discreet approaches, hands that remained close enough to suggest something, silent invitations that anyone else might have accepted. Izuku noticed all of this, but never took a step further.
Deep down, however irrational it seemed, his heart always belonged to Katsuki. As long as there was still the slightest possibility of one day being reciprocated by him, he couldn't choose anyone else.
If he ever decided to give up on Kacchan, it would only be when he was absolutely certain that he could never have him.
And, God... being there, in Kacchan's bed, with that masculine body before him seemed like madness. Surreal. Almost impossible. If someone had told him that this moment would ever come, Izuku would have laughed, convinced that it was an unattainable fantasy.
Now, however, everything was too real. The warmth of the room, the closeness between the two, and the way Katsuki looked at him made his heart beat so hard that he was sure the other could hear it.
“Deku... are you saying you saved that fat coochie for me? Is that it?” Katsuki asked with a crooked smile, full of that insolent provocation that was so characteristic of him, while his other hand slid down to the green-haired boy's hip, gripping it firmly.
Hearing Kacchan use such foul language directed at him made Izuku feel his entire face burn. His heart seemed to leap in his chest, and his head went completely blank for a moment. He never imagined that hearing that from Katsuki of all people would provoke such an intense reaction. He could barely hold his gaze for more than a few seconds before looking away, completely embarrassed.
“Deku, damn it! How many times have you kissed other people?”
Izuku immediately wrinkled his nose, surprised by the abrupt change of subject. The question caught him off guard, and he blinked a few times, trying to understand where it had come from.
“I'm asking you a question, damn it. Answer me.” The impatience in Katsuki's voice contrasted with the evident unease in his eyes.
The tone was aggressive as always, but there was something hidden behind those words: an anxiety he couldn't disguise, as if he really needed to hear Izuku's answer to calm the confusion that still gripped his head.
Katsuki's eyes were too deep. Red, intense, impossible to decipher. Izuku felt a pang in his chest at the thought of answering the wrong way and making him back away. He didn't want to lose that warm touch, nor the closeness he had dreamed of for so many years. After everything they had experienced that night, the mere thought of seeing Kacchan pull away again was enough to make him panic.
“Kacchan... I tried so hard to get you to talk to me, I tried so hard to get you just a little closer, I tried so hard to be your friend…” he said softly. It was difficult to speak with his cheeks pressed between Katsuki's firm fingers, but Izuku insisted, holding his gaze. “Yes, I’ve kissed some people... but I only wanna kiss you now. So, please, Kacchan... just put your dick inside already.”
The last words came out almost in a whisper, laden with all the anxiety he had been trying to hide from the beginning. His face burned with shame, but his eyes remained fixed on Katsuki's, sincere as always.
For Izuku, none of this had anything to do with the people who had passed through his life before. They no longer mattered. What truly mattered was the man in front of him, the one he had pursued for so many years, the one he had never been able to give up on, even when it seemed impossible to be reciprocated.
Katsuki clicked his tongue against the roof of his mouth. Deku wanted him to fuck him. The problem was that he didn't even know exactly how to do it. He had never gone this far with anyone, he had no idea what he should do first, and above all, he didn't want to show his own nervousness.
At least now he knew that Izuku had never had an experience like that either. Still, the mere thought of other idiots having already kissed those soft lips made his stomach churn. A bitter taste filled his tongue, and he hated realizing how much it still bothered him.
When Izuku, almost stealthily, raised his hips slightly, bringing their bodies even closer, the delicate lace fabric brushed against Katsuki's body, touching his extremely hard penis. The unexpected contact elicited an immediate reaction from both of them, making them hold their breath for a brief moment.
Katsuki closed his eyes for a second, as if finally understanding the magnitude of the situation they had put themselves in. There was no more room for denial. He wanted Deku as much as Deku wanted him.
The blond slowly released the green-haired boy's face and thought he heard a small sound escape his lips as his fingers left his skin. Without saying anything, he slowly lowered his face and body until his field of vision was once again filled with the delicate piece of lace that Izuku was still wearing. His concentration returned immediately, while an old memory surfaced in his head.
Kirishima.
Katsuki perfectly remembered his friend talking, days ago, about the conversations he'd been having with his girlfriend and how he was gradually learning to understand what made her feel good. At the time, Katsuki had ignored much of the conversation, calling it a stupid topic. Still, one specific phrase kept coming back to him at that moment. Kirishima had commented, with irritating pride, that he could make her "get there" in less than fifteen minutes.
Katsuki frowned. That instantly awakened his competitive side, a silent challenge for himself. If Kirishima could do it, he could do better.
A sly smile appeared on his lips as he looked back at Izuku's intimate area. Carefully, he again pushed aside the delicate lace fabric, now even wetter than before. His hands firmly gripped Deku's thighs, keeping them open in a clear message that he should remain exactly that way.
“Kacchan... what are you gonna do?” Izuku asked, completely surprised. He raised his torso slightly to meet the crimson eyes, his heart racing at the blond's determined expression.
“I'm gonna put your cunt in my mouth, Deku.” That didn't sound like a question, much less a request.
Before Izuku could answer anything, Katsuki closed the distance between them. The first touch of his tongue was cautious, almost experimental, as if he were still discovering that unknown territory. He began counting the minutes.
The contact was enough for Izuku to hold his breath. His eyes widened for a moment before closing tightly, while a shiver ran through his entire body. Instinctively, he tried to bring his legs together, overwhelmed by the unexpected intensity of the sensation, but Katsuki's large hands remained firm on his thighs, preventing any attempt to pull away and keeping him exactly where he was.
That magnificent taste exploded in his mouth, and Katsuki wanted more. He felt the soft skin of Deku's lower lips brush against his cheeks before surrendering completely to the exposed intimacy. Izuku screamed. Literally screamed in surprise.
Katsuki devoured him. He sucked his clitoris forcefully, almost aggressively, pulling, biting lightly, playing with his tongue in a strange delicacy, completely different from what Izuku expected from Kacchan. Still, it was clear he didn't exactly know what he was doing.
And Katsuki really didn't. He wanted to find out how far he could go, to understand every reaction of Izuku's body. So, his tongue slowly descended along his vulva and entered his wet vagina. Izuku rolled his eyes once more. His hands, marked by scars, ran to his blond hair, pulling it against his intimacy while biting his own hand to muffle his moans, arching his back against the mattress. Three minutes.
Katsuki smiled against his vulva. His other hand decided to explore as well. It moved up to Deku's stomach, tracing the sweat-damp skin, before slowly descending again, finding his swollen clitoris, even more sensitive than before. His fingers began to circle it, convinced he had finally found the perfect combination when Izuku began to babble completely incoherent words. "Kacchan" wouldn't leave his lips, while his hands pressed the blond's head tightly against his intimacy.
He was wrong.
The next instant, he wanted to find out where that path led. His tongue returned to the clitoris while his fingers searched for the entrance to the vagina. They slid in easily, as if Izuku's body was already waiting for them. Katsuki inserted two fingers at once, and the green-haired boy arched his back abruptly. Tears streamed from his eyes, and he ran one hand through his hair, squeezing the strands between his fingers.
Underneath the shirt that still covered part of his body, Izuku brought his other hand to his chest, searching for his own sensitive nipples in an almost desperate attempt to match the intensity of the sensations coursing through him.
Katsuki briefly raised his gaze over the mons pubis and observed Deku's state. The green-eyed man was breathing unevenly, biting his lips until they were almost sore, tears streamed down his face mingling with his runny nose, and his fingers kept clenching in the sheets and his hair. Five minutes.
He frowned.
Maybe he needed to go faster.
His movements gained rhythm, trying to maintain firmness and confidence, hiding his own lack of experience as much as possible. He didn't want to seem lost in front of Izuku, even though, deep down, he was discovering everything for the first time.
Izuku's interior was warm, tight, completely different from anything Katsuki had imagined. Each small movement seemed to be accompanied by the inner folds that enveloped his fingers, as if pulling them closer, drawing from him an ever-growing curiosity.
Deku's ragged breathing, muffled moans, and the way his body writhed on the bed, too small to accommodate both of them, composed a scene Katsuki never imagined witnessing. For a brief moment, his mind betrayed his concentration, imagining what it would be like to feel all of that differently.
When he decided to put a little more force into the movement, Izuku simply lost his voice. His body remained motionless for a second, and Katsuki froze immediately. His heart raced with worry. For a moment, he thought he might have fainted.
But Izuku's fingers remained firmly gripped in his hair.
Breathing a sigh of relief, he repeated the movement more carefully, attentive to any change in his expression. As soon as he returned to the same rhythm, Izuku arched his back again, and a new cry escaped his lips without him being able to stop it.
Seven minutes.
Katsuki narrowed his eyes.
Perhaps he had found the right spot.
Then Katsuki did it again. He increased the pace, intensified the movements, feeling the boy's body beneath him tremble more and more. Izuku cried, sobbed, breathed completely erratically, and mumbled pleas between moans.
Katsuki gave him everything he could, immersing himself in that discovery with the same intensity he put into any challenge.
It was so intense that, when the mental timer struck nine minutes and thirty-four seconds, he felt his fingers engulfed in a jet of thick, hot liquid. Izuku's body stiffened for a brief moment before completely giving way, his legs curled against his chest, and his breath faltered, deep and irregular, as the liquid flowed abundantly.
Katsuki watched everything with wide eyes, completely fascinated by the green-haired boy's reaction. He instinctively brought his fingers to his mouth, trying to understand this new sensation. He didn't find a strong taste or smell, and that only increased his curiosity.
Was this what Kirishima called "getting there"?
“Hey, Deku... your pussy is leaking water. Are you peeing?”
Izuku didn't answer.
Or rather, he couldn't answer.
His head fell to the side, his whole body felt too heavy to react, and his breathing took a few seconds to return to normal. Katsuki's eyes widened immediately, worry replacing his victorious expression. “Hey, you jerk! I did it so well that you fainted? Goddamn.” His voice came out louder than he intended, laden with a nervousness he would never admit aloud.
After a few seconds, Izuku finally opened his eyes slightly. Still panting, completely limp on the mattress, a tired smile appeared on his lips.
“Kacchan…” his voice came out low, hoarse, and broken by his breath. “Kacchan... I feel so good...”
Katsuki grinned proudly. This was definitely the "getting there" moment. He could already imagine his own superior look on his face as he rubbed it in Kirishima's face that he could be better than him, even at sucking pussy.
“So you came? Fuck... you came in my mouth, Deku, you damn pervert.”
Izuku didn't have the strength to retort. His body still trembled slightly, and he just smiled sideways, his cheeks completely flushed. Maybe Kacchan was right. Maybe he really was a pervert.
Katsuki still wasn't satisfied. He wanted to see Izuku completely, without any obstacle between his eyes and the green-haired boy's body. With a brusque movement, he pulled the panties off his legs, startling Izuku with the speed of the gesture. Immediately afterward, he grabbed the hem of his shirt and removed it with the same agility, leaving him completely exposed before him.
For a moment, Deku's eyes widened, almost as if he believed it would all end there, but it only took meeting Katsuki's hungry gaze to understand that he was far from wanting to stop.
“I wanna put it inside of your tiny cunt, Deku.” The phrase came out low, firm, without any hesitation.
Izuku's eyes slowly descended to the still completely rigid penis in front of him. A small drop of liquid glistened at the tip, and, for a moment, the green-haired boy felt like his heart was going to leap out of his chest. His gaze sparkled in an almost silly way, as if there really were small hearts hidden within those emerald eyes. “Is Kacchan going to fuck my pussy out?”
Katsuki shuddered.
The sweet, innocent, and completely sincere way that phrase came from Izuku's lips was diabolical. It messed with his head more than any provocation could have.
“I'm gonna fuck you until you forget you weren't mine, you fucking Deku!”
And he really would. He was going to figure out how to fuck that idiot nerd so hard that Deku would have to take a few days off from hero duties to recover from the damage Katsuki intended to do.
Izuku swallowed hard and nodded. That was exactly what he wanted most in the world.
Still trembling, the green-haired boy leaned on his hands and knees, feeling the cold send shivers down the spine. He crawled slowly to the edge of the bed, where Katsuki stood, and looked up at the rigid penis in front of him, his eyes shining with a mixture of curiosity and desire. His body was still weak, his breathing uneven, and his legs trembled slightly, but even so, he didn't want to stop.
Carefully, he took one hand to Katsuki's member and wrapped his fingers around it. It was heavy, much more so than it appeared, warm and thick to the point that Izuku couldn't completely encircle it with just one hand. He tilted his head, observing it attentively.
Unlike Kacchan, Izuku had already watched some pornographic films and videos. He wasn't obsessed with it, but he had a reasonable idea of how things usually happened and, at that moment, he hoped that little bit of knowledge would be enough to help him.
He tilted his head forward and smelled the sweat emanating from Kacchan. His green eyes slowly traveled up the line of hair that crossed his abdomen, past his navel, his broad chest, and finally met the ruby eyes. He wanted to memorize every detail of that image forever, as if he had waited his whole life to see it so closely.
Delicately, he stuck out his tongue, carefully lifted the penis, and ran it along its entire length in a slow movement, feeling the salty taste of sweat invade his palate. Katsuki groaned loudly for the first time that night. He had never experienced a sensation like that. His whole body tensed, his stomach churned, and his member throbbed at the mere contact with Deku's warm saliva.
Damn Deku.
With those innocent eyes, he was doing the most indecent thing Katsuki could imagine.
Izuku continued exploring the member with the same caution, tracing every inch as if he were discovering something precious. Gradually, he concentrated on the reddened and sensitive glans. He moved even closer, maintaining delicate movements, while saliva slowly dripped down its entire length, making everything even more slippery. Before him, Katsuki's lips parted slightly, unable to contain his own body's reactions.
Shortly after, Izuku felt strong fingers close in his hair. Instinctively, his heart raced. He expected Katsuki to guide him, to hold his head tightly or try to control his movements. But that didn't happen. The hand remained there, simply caressing his hair firmly, without pushing or forcing him to do anything, and that unexpected gentleness, coming precisely from Kacchan, surprised him greatly.
“Shit... argh, Deku! ” he gasped loudly, as if the complaint had been stuck in his throat.
Izuku immediately thought he was doing something wrong and hurried to back away. Before he could retreat completely, however, Katsuki gripped his hair more firmly, preventing him from leaving. Surprised, the green-haired boy brought his face closer again and opened his mouth, cautiously taking in part of that thick member.
He felt the weight on his tongue and his eyes filled with tears when the glans touched the back of his throat. A different, slightly bitter taste invaded his palate, making him stop moving for a moment. He raised his eyes and met the flushed gaze above him, full of enigmas he couldn't decipher. He wanted to ask if Kacchan was enjoying it, he wanted to know how he preferred it, he wanted Katsuki to guide him in this discovery. But Kacchan didn't know any more than he did.
Izuku would have to figure it out on his own.
His rough hand enveloped the base of the member, trying to alleviate some of the difficulty. With his cheeks puffed out, so round they resembled a hamster's, he took a deep breath and tried to recall the few videos he had watched. He gathered as much saliva as he could and began to move slowly again, trying to find a comfortable rhythm. In practice, it was much more difficult than it seemed.
Even though he was almost certain that his teeth grazed Katsuki's member at times, the blond didn't complain once. On the contrary. He groaned completely uncontrollably, panting between breaths, keeping his eyes tightly closed, as if all his concentration was focused solely on Izuku.
Not even the green-haired boy's evident inexperience seemed to diminish the pleasure he felt, and this only made Deku even more determined to learn, little by little, what made Kacchan react that way.
Even though Katsuki had never had sex, he had touched himself before, and therefore knew how difficult it was to achieve orgasm. He didn't expect that, by having sex, this difficulty would simply disappear. He knew his own body well enough to recognize the sensation preceding orgasm and could say, with absolute certainty, that he wasn't close to it yet.
But it only took Izuku's tired face to move away from his dick for all that conviction to waver.
His mouth remained slightly open, reddened by the effort. His green eyes were watery, glistening behind the tears, the freckles scattered across his pale face seemed even more evident, and his breathing was completely erratic. Damn... that sight alone was enough to mess with Katsuki's head. When his gaze lowered a little more and found Izuku's own fingers digging into his own vagina, as if desperately trying to cope with what he was feeling, his whole body tensed.
Shit.
He could come right there, staring at Deku's beautiful face.
And when Izuku was about to do it again, Katsuki pulled away.
He didn't want to come yet. She wanted to prolong that moment as much as possible, to understand every sensation her body was capable of provoking and to feel alongside Izuku. She wanted to discover what it would be like to have him so close, to observe every expression etched on that freckled face, to hear every sound that escaped those red lips. No. It wasn't over yet.
So, he pushed Izuku back onto the bed and climbed on top of him.
This time, their bare chests met, and both let out a low, involuntary moan at the mere warm contact of their skin. Katsuki took Izuku's thick lips again with conviction, without the hesitation of before, while his large, marked hands slid down the green-haired boy's legs. His mind worked fast, trying to imagine the best way to position him in that way, one in which he could observe every reaction of that idiot nerd without missing a single detail.
Then he held one of Izuku's legs and, breaking the kiss for only an instant, lifted it until it rested on his own shoulder. He mentally thanked Deku for his absurd flexibility when he tilted his face to capture his lips again and realized that he remained in that position with surprising naturalness, as if he completely trusted any decision Katsuki made from then on.
Katsuki tried to guide his own penis in the dark. He couldn't quite see what he was doing. When he felt that familiar moisture touch the head of his member, he groaned against Izuku's lips and moved forward slowly, little by little.
Not that it was really necessary. Izuku received him so well that it was as if he had been magically sculpted for him. There was no resistance; everything happened with almost absurd ease, his cock was squeezed by Izuku's inner folds, and the sensation of being welcomed in that way made Katsuki's entire body tremble.
His hands slid down to Izuku's waist and ended up finding his hips, warm under his fingers. They were too sweaty. Before he even realized it, small explosions crackled in his palms, illuminating the room for a brief moment and sparking on the green-haired boy's skin.
“Kacchan! My God... what was that?” Izuku exclaimed, his voice escaping more mischievously than he intended, while his green eyes widened for a moment, alternating between surprise and a shy smile that insisted on appearing.
Katsuki's cock continued to enter and he continued to moan. He felt like he was being torn apart inside, even though the movement was delicate, attentive. Katsuki was huge, after all, nothing would change that.
“Shit, my bad” He immediately removed his hands from Deku's ass.
“That was…” a moan “Damn, Kacchan, that was so good.”
Katsuki expected everything, except that Izuku was a masochist, except that he liked feeling pain. So he smiled at the information, returned his hands to where they were and, this time, purposefully, released small explosions (which came out bigger than he expected, due to the excess sweat) against the freckled skin.
Izuku moaned loudly, shouted his name.
“Louder, Deku!” He kissed Izuku's cheek and licked the sweat that trickled down his forehead. “Louder, so everyone knows who's eating this fucking delicious pussy!”
Izuku couldn't think straight when Katsuki's penis filled him completely, all the way to the end. It hurt. It hurt like hell to feel that monster opening him up completely, even though the movements remained careful. But he didn't want it to stop. He wanted Kacchan to continue, he wanted to feel every second of that closeness, he wanted to keep that feeling forever. After so many years longing for that moment, it was almost impossible to believe it was really happening.
His body trembled uncontrollably. His legs wobbled, his fingers gripped Katsuki's broad shoulders, and his breathing was completely erratic. Between the pain, the adrenaline, and the overwhelming happiness of finally being in Kacchan's arms, Izuku could only repeat his name amidst the moans, unable to organize any other thought.
Katsuki felt his heart racing. He had hoped to maintain the confidence of someone who knew exactly what they were doing, because, in truth, he didn't. All of this was completely new. In his mind, getting inside Izuku couldn't be that complicated. Was it just... a matter of retreating and returning? Was that enough?
He took a deep breath and decided to try.
He pushed his hips back, feeling his own body shudder at the change in sensation, and then lunged forward with too much force, far more than he had intended. Izuku shuddered immediately, clutching his muscular arms desperately. His short nails dug into the damp, sweat-soaked skin as a tremor ran through his entire body.
It was at that moment that Katsuki knew that, despite the unintentional brutality, he hadn't completely failed.
Izuku's eyes closed tightly, his cheeks flushed even more pink, and his lips parted in an expression Katsuki would never forget. The green-haired boy's reaction was enough to send a shiver down his spine, dissipating some of the insecurity that had been weighing on his chest. Perhaps all he had to do was pay attention to Izuku.
He did it again. And again. And again.
The bed banged hard against the wall with each movement, but Katsuki didn't care. Izuku groaned too loudly, but he didn't care either. He was completely focused on observing the green-haired boy's reactions, curious about every change in his expression. Whenever Izuku's body trembled and his face contorted in a different way, Katsuki felt a strange satisfaction growing inside his chest.
There were moments when his body found something softer, deeper, and he frowned, trying to understand exactly what he was feeling.
His mouth watered at the thought that crossed his mind. He was pounding Deku's cervix with his penis. It was absurdly perverted, irresponsible even. On another occasion, perhaps he would have worried more about himself for thinking that way. But, at that moment, Katsuki simply didn't care. At least, not now.
Overcome by an almost unbearable curiosity, he realized he wanted to see better what was happening between them, he wanted to see exactly how Deku's receptive vagina enveloped his penis. He wanted to observe Izuku from another angle, to memorize every reaction of that body trembling beneath his. So he slowly released the grip the green-haired boy held in his arms and leaned his own body back.
Damn.
His penis went in and out with a wet, indecent sound. Deku's cunt welcomed him in an almost unbelievable way, warm, small, completely surrendered to the rhythm that Katsuki was still improvising. With each movement, it was as if his body held him a little tighter, refusing to let him escape for even a second.
Katsuki brought one of his fingers back to his clit, which had been momentarily forgotten. The touch alone was enough to make Izuku tremble all over. His toes curled on the mattress, his legs trembled, and his breath hitched once more. His throat burned from calling Kacchan's name so many times, and the moans now came out hoarse and broken, while his eyes remained tightly closed.
His entire body burned. There was a growing pressure in his abdomen, intense and impossible to ignore, spreading through every muscle. Izuku no longer knew if he wanted that sensation to lessen or intensify even more. All he could do was cling to Katsuki, breathing unevenly, completely lost in the avalanche of sensations that was taking over his body.
“Kacchan... God, you're so good... Kacchan, so good to me...” he groaned completely incoherently, unable to organize his own thoughts.
“Am I, Deku?” he asked, a crooked smile appearing on his lips as he attentively observed each reaction of the green-haired boy. “Shout, Deku. Say who you belong to. Say who's fucking that greedy cunt.”
There was an almost cruel smile plastered on Kacchan's face. Izuku still managed to see a drop of sweat trickle down his blond eyebrow before his vision blurred slightly again. His breathing was completely erratic, his chest rising and falling too quickly for him to formulate any coherent thought.
“Kacchan is the best... Kacchan... fucks me so well...” He replied between sighs, his voice low, hoarse, much more timid than Katsuki would have liked.
Then he went up to the boy and grabbed him by the neck. Izuku thought nothing could excite him more. But it could. Kacchan forced his neck so he couldn't breathe, leaving him seated while he continued pounding his pussy with incredible skill.
“I want you to scream it, fuck!” he spat in Izuku's face.
“Kacchan fucks me good! Oh Ka-cchan! Fuck me!” Izuku screamed for real. His voice echoed through the room, his vocal cords burned with the effort, and he ended up coughing soon after, panting, trying to catch his breath while still held captive by Katsuki's intense gaze.
Katsuki smiled, satisfied, and pulled Izuku by the thighs so that he was on top of him for a moment. The position, however, didn't last long. Soon the green-haired boy was put back on all fours, his ass sticking up towards Bakugo. His body trembled, his pussy throbbed, empty, and tears continued to stream down his face.
Izuku's chest remained completely supported on the bed, while Kacchan's large body covered him from behind. Katsuki pulled him closer by the waist, holding him firmly against him. He thrust his own cock into that tight pussy all at once. The groan that escaped Izuku was immediate, hoarse, and uneven, making Bakugo hold his breath for a brief moment before resting his forehead against his back again, completely enveloped by the intensity of that instant.
That position was new, different. It went deeper, much deeper. Izuku saw stars when Kacchan grabbed his buttocks and spread them apart. Midoriya didn't know this, but Katsuki stared at his anus for a long moment. Curiosity burned in his chest; he wanted to know what it tasted like too. But perhaps it wasn't the right time yet.
So he just kept thrusting without stopping.
When Deku tried to get up, Katsuki brought one hand to his head, gently pushing his cheek so that it remained against the bed, forcing his butt to stay raised. The gesture was firm, almost instinctive, while the blond kept his eyes attentive to each reaction of the green-haired boy, as if he wanted to memorize them all.
Izuku moaned like a first-rate slut. He knew the moans in porn movies were fake, theatrical, rehearsed to seem convincing. But Katsuki's thick penis also seemed theatrical. The way it reached the depths of his body was too absurd to be real. It was impossible to contain his own sounds when his partner was that big, making each movement elicit an involuntary reaction from his chest.
“Kacchan! Kacchan, harder!”
That was an affront.
Katsuki smirked. He could increase the pace as much as Izuku wanted. He had plenty of strength, plenty of stamina. He was a hero, after all. His body had been shaped by years of training, explosions, and combat, and he didn't intend to back down anytime soon. He could continue for as long as necessary, until Deku completely lost the ability to formulate any coherent thought, until he could only repeat his name and forget about anyone else who dared to get too close to him.
Then Katsuki did it.
Harder. Deeper.
Izuku screamed. He couldn't tell if it was from pain or pleasure anymore, maybe it was a bit of both. He only knew he didn't want Kacchan to stop.
Katsuki's sweat dripped onto Izuku's warm back, slowly trickling down his skin to the nape of his neck, disappearing among the short green strands of hair that sprouted there. The salty drops ran the length of his back, leaving a damp trail wherever they went.
Katsuki realized he was nearing his limit when he felt Deku's inner walls contract around him. Izuku pulled him closer with his calves, as if he couldn't bear the thought of letting him move away even for a moment. No coherent sound came from his throat anymore; his voice had been lost among the screams and uneven breathing. Still, the wet sounds that filled the room said more than any words.
Katsuki smiled, satisfied.
He continued at the same pace, without interrupting a single movement, prolonging that moment as much as he could while observing, fascinated, every reaction etched on Izuku's face.
He pushed Izuku back onto the bed and turned him over. He wanted to watch his cute little face while he came inside his pussy. He needed that. Then he put him back on his back on the mattress and continued thrusting, fast, like a machine, as if his own body were incapable of tiring.
It was when Izuku sobbed, and thick tears rolled down his cheeks, that Katsuki came.
Damn.
He came hard.
He felt his abdomen contract, his core churn, and his mind be engulfed in a thick fog as he filled that hole with all his life's fruit, to the very bottom, unable to stop his own body. He continued panting, his muscles tense, feeling the heat between them as he remained completely lost in that sensation he had never experienced before.
“Kacchan is so good...” Izuku murmured. His green hair was stuck to his forehead, and his chest rose and fell in completely uneven breathing. “Your dick is amazing, Kacchan. You're amazing.”
Of course Deku would get emotional after coming, it was just like him. Katsuki didn't answer.
He kept his head down, watching his own penis slowly lose its rigidity inside the now familiar vagina, as reality finally began to catch up with him.
He had fucked Deku.
He had fucked Deku because he was dying of jealousy over him with another idiot.
Whatever. Deku needed to know his place. He needed to know that Katsuki was in charge of their relationship.
And Katsuki withdrew slowly. Along with his now flaccid penis, his white semen, saved for months, accompanied him. He instinctively lowered himself, watching as his cum dripped down the soft folds. He found that scene too beautiful. He felt a strange pride grow in his chest.
Then he lay down next to Deku on that cramped bed, pushing the small body so that they both fit better on the narrow mattress.
“So, Kacchan...”
Shit. that nerd couldn't shut the fuck up for even five minutes.
“I'm yours, huh?” Izuku's voice came out hoarse, low, worn down by the moans from earlier. There was a small smile hidden at the corner of his lips, and that made a strange pride warm Katsuki's chest once again.
“You are, you damn nerd!” he replied almost immediately, without the courage to meet the green eyes. He kept his gaze lost on some point in the room, while his cheeks remained flushed and his breathing, still heavy, tried to return to normal. It was ridiculous to admit anything looking at that idiot's face.
Izuku let out a tired chuckle, turning his face slightly in his direction. He observed Kacchan's profile for a few seconds, as if memorizing every detail of that sulky expression he had known since childhood, before smiling again.
“You're really bad with feelings, Kacchan.«
Katsuki snorted through his nose, annoyed by how absurdly easy it was for Deku to see through it. He clicked his tongue against the roof of his mouth and replied before he could think too much about it. “And you're a fucking slut that loves cock, Deku. Who's worse?”
Izuku fell silent and took advantage of the silence to snuggle into Katsuki's broad chest. His fingers absentmindedly traced the still-damp, sweaty skin, eliciting a discreet shiver from the blond, who pretended not to notice.
Katsuki was about to truly confess his feelings. About to admit that all of this left him completely confused, that Deku had been messing with his head long before either of them realized it. He was about to change that strange situation between them when two firm knocks echoed from the other side of the door.
“Did you two finished it?” It was Iida. Who else could it be?
Katsuki rolled his eyes at the exact same moment, while Izuku's eyes went wide, freezing on top of his chest.
“That was inappropriate! Highly inappropriate! Terrible! You are my friends, and I will not report this to the teacher, but this situation must never happen again!” Iida shouted from the other side of the door, clearly outraged. “It was traumatic for your friends! Do I need to remind you that intimate contact is not allowed inside the school! Under no circumstances!”
“Iida... maybe that's enough already...” Yaoyorozu tried to defuse the situation before it got even more out of control.
“They need to be made aware! That behavior was disrespectful, reckless, and completely incompatible with the conduct expected of heroes!”
“Iida, I think they've already understood...” Yaoyorozu's weary voice was heard again, trying, once more, to calm the class representative.
“They didn't understand! The door has been locked for almost an hour! They need to come out and explain themselves!”
Bakugo coughed, irritated. He couldn't even get a single second of peace after cumming.
“Actually...” Kaminari interrupted, struggling to hold back his laughter. “It's been almost two.”
A heavy silence fell over the hallway. For a brief moment, no one said absolutely anything, as if they were all processing that information at the same time.
Even Iida seemed to lose his words, while on the other side of the door, Katsuki closed his eyes and ran a hand over his face, feeling a belated sense of regret beginning to creep in. Not because of what he'd done, of course. But because, apparently, the entire class had been waiting outside for almost two hours.
“Two...” Izuku murmured, completely red-faced, staring at Katsuki as if he still couldn't process it. “Kacchan...”
“Don't even open your mouth.”
“Everyone was waiting?”
“Shut up.”
“Kacchan...”
“Shut it. Let's make them think we're asleep.”
From outside, a familiar burst of laughter echoed through the hallway.
“I told you they were making out!” Kirishima cheered. “You all owe me five thousand yen!”
“YOU PLACED A BET?!” Iida shouted, outraged.
Katsuki ran a hand over his face, clearly irritated by how absurd the whole situation had become.
“I'm gonna kill Shitty Hair.”
Despite the embarrassment that seemed ready to swallow him alive, Izuku couldn't hold back a quiet laugh, muffling it against Katsuki's chest as he tried to hide there a little longer, as if that would somehow fix anything.
Katsuki stayed silent for a few seconds, staring at the ceiling as if calculating the best way to survive this without killing half the class in the process. One hand still covered his face, but the tension in his jaw made it clear he was one step away from exploding—and not in the Quirk sense.
Still tucked against him, Izuku took a deep breath, trying to get his embarrassment under control, but the quiet laugh that slipped out betrayed the fact that he was losing that battle.
“This isn't funny, Deku,” Katsuki grumbled, though his voice lacked the same aggression as before.
“Sorry...” Izuku murmured, though he didn't sound particularly sorry.
Katsuki let out a sound somewhere between a sigh and a grunt, clearly trying not to lose it while the reality outside the room continued to exist with absolutely no shame.
Out in the hallway, the argument continued like organized chaos.
“I demand that everyone return to their rooms immediately!” Iida insisted, his voice growing increasingly shrill, as though he were about to collapse under the weight of moral responsibility.
“Relax, Iida, it's not like somebody died.” Kaminari replied, still laughing, as if this were just another ordinary night in the dorms.
“THAT IS NOT A REASON TO LAUGH! THIS IS PRACTICALLY A SOCIAL FUNERAL!”
“Technically, they're just... making love. There's nothing wrong with making love ” Kirishima added, completely unconcerned, as though he were commenting on the weather.
“DON'T SAY THAT OUT LOUD! ” Iida nearly choked on his own outrage.
Inside the room, Katsuki suddenly sat up in bed, yanking the blanket with force as if that could somehow erase the existence of all the idiots on the other side of the door.
“I'm going to destroy every last one of them” he muttered quietly, his voice carrying a dangerous calm.
Izuku finally sat up as well, slowly fixing his messy hair, still blushing but looking much more composed. He glanced sideways at Katsuki as if he were far too used to this kind of emotional outburst from him.
“You're not doing that, Kacchan.”
“Yes, I am.”
“No, you're not.”
Katsuki turned to look at him. Still irritated. Still red. But now there was something different there, something that wasn't just anger—it was exhaustion, confusion, and somewhere in the middle of it all, a strange hesitation he didn't know how to name.
“You're defending them now?”
Izuku smiled faintly, tired but genuine, as if the answer were far too simple.
“I'm trying to stop you from getting expelled during our first month of dating.”
The word landed in the middle of the room like something far too solid to ignore.
Dating.
Katsuki blinked once. Then again.
The silence between them grew heavier than the noise in the hallway.
“...Who said this is dating?” he asked, more quietly than he would have liked, as though he were testing his own pride.
Izuku tilted his head calmly, almost as if he'd been expecting exactly that response.
“Then what is it? You wanna fuck me for free and leave?”
Silence.
Katsuki opened his mouth, then closed it again. He ran a hand through his hair once more, irritated with himself, as though any possible answer were harder than any fight he'd ever won. He didn't wanted that.
“...Shit.”
Izuku laughed softly again, in that light way that always seemed to slowly dismantle Katsuki.
And for the first time that entire night, Katsuki didn't tell him to shut up. Maybe he should thank that damn Todoroki later. As if he would.
