Work Text:
It was a random class, on a random Tuesday, and Ectoplasm was going over the material for their third-year finals. It was afternoon already, their last period of the day before they were sent to the dorms again. Katsuki felt his eyes start to close out of boredom, he almost let out an audible yawn. He doesn't think he's ever been this bored in his life. As he felt his consciousness slipping, Ectoplasm's voice echoed in his head, though it wasn't directed at him, rather, he was speaking to the walking battery sitting just a few seats away.
"Yes, Kaminari?" He called, and Katsuki turned his head sluggishly to see his boyfriends hand raised.
"Uh.. I gotta leave," He said, already packing his things into his bookbag chock full of hero merch (including a limited edition Dynamight keychain). "I've got a doctors appointment. My permission slip is right here," Pulling a crumpled piece of paper from his jacket pocket, he showed it to their teacher, who inspected it before nodding.
"Hm. Make sure to go over the material. Your final is in a week." Ectoplasm hummed, voice monotonous as ever, "And good luck, I suppose."
"Yep yep. Don't worry, it's just the optometrist. Thanks though!" Denki smiled brightly, bowing briefly before hitching his backpack onto one shoulder, walking out the classroom.
Katsuki rolled his eyes, laying his head in his hand on the table. He was so bored.
The next day, Katsuki had seen Denki in the little kitchenette before school, still in his pajamas— A band shirt that most certainly belonged to Katsuki and some sweatpants— But, more notably, he had glasses. Basic little things, black with an almost rectangular frame, slightly thick too. They were pushed down his nose, and Denki seemed too out of it and exhausted to care to adjust them, more focused on making himself a cup of cloying syrup mixed with straight up sugar and a side of coffee.
Katsuki crossed his arms over his chest, leaning on the doorframe, just.. Inspecting him. Denki didn't notice him yet, clearly too focused— Or too tired, maybe both, but.. Fuck, the way the glasses framed his face. They looked perfect on him, just sitting on the bridge of his nose.
Bakugo cleared his throat, making Denki jump,
"You got glasses?" He questioned.
Denki whipped his head around to look at him, adjusting his glasses so they weren't so crooked.
"Oh-! Yeah! You, uh.. You like em?" He asked sheepishly, smiling at him giddily. Katsuki scoffed.
"They look fine." He rolled his eyes, shrugging. They looked more than just fine. Denki's smile turned into a grin, and he just hummed contently, turning back to his 'drink' (if it could be called that) and shrugging.
"Hah? What're you smiling about, dumbass?" Katsuki asked, walking up to him.
Denki no longer felt threatened whenever Katsuki tried to be intimidating, he knew he was all bark no bite, so he didn't even look away from his cup.
"You like em." He chuckled, pouring copious amounts of milk into his concoction, which, frankly, couldn't even be considered coffee anymore.
"Like hell I do." Katsuki scoffed, shoving Denki lightly. Maybe Denki just knew Katsuki too well, or maybe it was the soft blush dusting his face that gave it away. But he knew. And Katsuki knew he knew.
"..That looks disgusting." He commented, nodding in the direction of his boyfriends cup.
He gasped dramatically, taking a step back;
"How dare you! It's delicious!"
He scoffed, clearly offended, taking a sip from the mug to emphasize his point.
"It's going to give you diabetes." Katsuki retorted, crossing his arms, cocking an eyebrow at him.
"Whatever." Denki huffed, turning to him with a pout.
Katsuki blinked at him. He looked good normally, sure, but especially with the glasses, holy shit.
His hair was in a messy low ponytail, unkempt with his bangs all over his eyes, fringe framing his face, brows furrowed and eyes crinkled, lips downturned in an annoyed, almost bratty pout. His glasses hitched up on the bridge of his nose, just a little bit crooked.
He looked almost.. disheveled.
It made Katsuki feel like a degenerate, but he couldn't help but think about how he would absolutely make Denki keep his glasses on if they fucked.
Not because it's a kink, of course not. Katsuki just thinks Denki should be able to see whenever he fucks him.
They'd get crooked, or fall off when Denki would turn his head to the side, and Katsuki would push them back into place for him.
Or, if Denki was giving Katsuki head, down on his knees, looking up at him with tear-filled eyes, amber meeting carmine, glasses still on his damn face, probably sliding down his nose, because Katsuki's just so damn aggressive.
Or the way Denki looks at Katsuki when he's being a tease because he likes riling him up.. Katsuki can imagine it.
Fuck. Fuck fuck fuck. Katsuki can imagine it too well. He had to look away, stop thinking about it.
He was not about to get hard over his boyfriend wearing glasses. That would be so fucking lame, and they had classes soon.
"Kacchan?" Denki called, waving his hand in front of his boyfriend's face. "Earth to Kacchan.." He stepped closer, leaning in a bit.
"Fuck, fuck- I'm fine—" He stammered, but really, he wasn't. Fine, that is. Denki probably knew that, what with the way his blush reached his ears.
"You really like them that much?" Denki's voice dropped a whole octave, and it sent shivers down Katsuki's spine and heat straight to his core. He looked down. Only semi-hard, he huffed in annoyance, looking back up only to see Denki's eyes on his dick as well.
"Damn, Kats." He chuckled impishly, taking his cup of.. Whatever he's drinking, ruffling his boyfriends hair with his other hand, and walking past him, brushing his shoulder with his own. Intentionally.
Katsuki's eyes followed Denki as he walked out of the kitchenette and into the common area,
"Fucking bastard." Katsuki managed, grumbling quietly before taking a deep breath to try and calm himself down.
Katsuki doesn't know how he managed the whole day, but he did. Even when Denki snuck him teasing glances in class, or threw a paper note to him with a 'Hey Kacchan' written on it accompanied by a little chibi drawing of himself, glasses and all, or when he managed to pin Katsuki down to the floor during training, or, the most egregious offense, touching his thigh underneath the lunch table. Katsuki locked himself in his dorm after classes, despite his friends suggesting they go out to eat or watch a movie. He would rather die than be in the same room with Denki if they weren't fucking each other.
Lying down on his bed, he stared at the ceiling and sighed deeply through his nose, letting out a breath he didn't know he was holding. His face was flushed even now. Resting his forearm over his eyes, Katsuki murmured; "What the fuck is wrong with me.." He felt perverse. They really were just glasses, and Denki didn't even need to do anything for them to invoke a reaction from Katsuki.
Katsuki was never one to have perverted thoughts. He hardly gave his brain room to think about his kinks, or the things he was attracted to. He just liked what he liked, but this whole ordeal made him start reconsidering. Denki was the complete opposite. Katsuki had managed to pry more than one of his biggest fantasies out of him during sex, which made it very clear that Denki put a lot of thought into his sex life. Katsuki never fantasized like that. He hardly even thought of Denki in sexual ways unless they were actually screwing. Until today, at least.
God, thinking about all this was giving Katsuki a headache.. He sighed, removing his arm from his eyes, keeping them closed shut.. Until there was a knock at his door.
Katsuki knew who it was. Of course, it was Denki. Because who the fuck else would it be?
He furrowed his brows, keeping his eyes closed for a few moments, taking a deep breath through his nose, and getting up. If he opened the door, they'd probably end up having sex. But that was most likely what Denki wanted from him anyways.
Katsuki clicked his tongue, curse his boyfriends stupidly high libido.
..He ignored the fact that this was his own fault.
He huffed and went to the door, unlocking it. Unsurprisingly, his boyfriend stood there, hands behind his back, stupid glasses on his equally stupid face, expression completely innocuous. But Katsuki knew better. It was fake. A carefully crafted mirage of innocence.
A soft smile settled on Denki's lips when he was greeted with Katsuki's face. He looked as unimpressed as he did flustered.
"What's up, babe?" Denki asked curiously, eyes inspecting him up and down as he did.
"What's up?" Katsuki echoed, leaning on his doorframe, arms crossed, brows furrowed. "You're what's up. You came here." He said, clearly annoyed. His standing in the doorway didn't seem to deter his boyfriend from entering his dorm like he owned it, since he simply pushed past him and lied down on his bed. Katsuki clicked his tongue, turning around, shutting the door behind him and locking it.
Denki's eyes drifted to Katsuki once he realized he'd locked the door;
"Oh?" He voiced, seemingly amused.
Katsuki scoffed, fed up with Denki's antics, sitting down on the bed, turning to look at his boyfriend, desperately forcing himself to ignore the tanned skin that showed where his uniform shirt rode up.
"Is this fucking fun for you? You like this?" He asked disgruntledly, narrowing his eyes at him.
"Yeah." Denki hummed, sitting up and climbing into Katsuki's lap like he owned him, too. "How could I not? It's a huge ego boost, y'know." He grinned at him. It made Katsuki's head spin.
"Get off my lap, you degenerate." He said, despite the fact that his hands were already on the sides of each of Denki's thighs. The dichotomy between his words and his actions was painfully apparent, Katsuki knew that, but he couldn't help it. His pride would just cease to exist if he gave up so easily.
In the back of his head, Katsuki wondered how kissing Denki would feel. His nose or forehead would probably end up clashing with his glasses, but.. That made the thought feel hotter.
He was so fucked. What had Denki done to him? Katsuki thought he was immune to his boyfriend's depravity, but apparently it rubbed off on him at some point.
Kaminari only chuckled,
"You're so cute when you're mad, Kacchan," He teased, wrapping his arms around his neck, leaning in to kiss him. Katsuki's eyes fluttered shut, only to be met with a kiss on the corner of his lips.
He clicked his tongue, opening his eyes to glare at his boyfriend when he pulled away.
"Are you serious?" Katsuki asked, like he couldn't believe how much of a tease Denki was.
"Serious about what?" He asked, lilting his voice and batting his lashes at him. Katsuki would find it cringe if his lashes weren't so damn long, and if he wasn't doing it though his god forsaken glasses.
"I'm always serious about you, babe." He giggled when Katsuki slid both hands under his shirt, gripping his hips,
"Like hell you are. You're never serious," He said, enjoying the way Denki leaned into his touch.
"Am too." He argued, "Not my fault you're secretly some huge pervert with a glasses kink," He leaned in to flick his forehead, forcing an annoyed groan from the other.
"I'm fucking not!" Katsuki denied, "You- You're doing something," He accused, lying his head on Denki's shoulder, sighing as he pulled him closer by the hips, "I just know it."
"Katsu, I'm not doing anything. I'm wearing glasses, and you like it way too much." Denki snickered, "Do you see me doing anything special? Wearing some new cologne with aphrodisiacs in it or something?" He asked, eyes fixed to him, wrapping his arms around his back. Katsuki was apparently just as weak as his argument, so he had nothing to say to that. "Thought so." Denki said.
Everything was so hot, Denki's body heat radiated all over, it made him feel like he was going insane. He was hiding his face in his shoulders pathetically, "Fuck, what's wrong with me." He asked, voice cracking.
"Nothing." Denki said, bringing a hand up to play with his hair. "You just have a kink. And that's okay." His voice was so soothing, but Katsuki couldn't tell if it was genuine or not. Denki was good at that. Obscuring his intentions.
"It's a shitty kink. Am I just gonna get a fucking hard on every time I see you now?" He groaned at the thought. His life would be over if that was the case. The thought made Denki laugh,
"Probably not. I'll switch to contacts if you find me that irresistible, though." He hummed. Katsuki rolled his eyes, holding on tighter.
"Shut up." He demanded. He could smell Denki's cologne on the fabric of his button up. It was intoxicating, made his head spin a little.
"Yes sir," Denki said, voice a little breathy. It was all fake though, just an image of obedience. Not even a second passed, and he was already talking again; "You know," He muttered, "You love acting like you hate this, but," He grinded his hips down, making Katsuki tense. He forced himself to bite the grunt in his throat down. "We both know you're lying." Katsuki could not force himself to move, to look Denki in the eyes and challenge him. They both knew it was true. His grip on Denki's hips only tightened, and Denki wasn't sure if Katsuki was trying to get him to grind down again or keep him in place. He could feel how hard he was just sitting on his lap.. "You think I'm hot," Denki said quietly, cupping his face, pulling him away from his shoulder, "Don'tcha, Kats?" He forced the eye contact, keeping Katsuki's face in place. Denki's eyes were somewhat crinkled, his expression radiated confidence, it was almost intimidating. Denki. Intimidating.
And Katsuki wanted nothing more than to nod over and over again, because he absolutely thought Denki was hot. His pride be damned, Denki's eyes were borderline hypnotic.
Denki narrowed his eyes at Katsuki, tilting his head. It was apparent that Katsuki was trying to get Denki to grind down again now, but he stayed exactly where he was. "No?" He asked.
Right.. He was waiting for a response. Katsuki should know his sadness is feigned, Denki makes it all too obvious, but it makes his heart drop anyways.
"N-.." Katsuki didn't know how to respond. "..Mh." It wasn't an affirmation or a denial. He tried to make it sound as indifferent as possible. But it came out more like a whimper.
"You can use your words, can't you?" Denki teased. Katsuki's grip on his waist still hadn't let up.
"Yeah," His voice cracked, shook a little. "You.. Yeah." He tried again, willing himself to sound firmer this time. Denki seemed to take it as an answer, though.
"You like my glasses?" He asked, tilting his head at him. His expression, his tone, they were so kind, so deceiving.
Katsuki fell silent again, trying to look away, though his head was still facing Denki.
"Eyes on me, Kats," Denki said, and like a magnet, Katsuki's gaze fell back on his. "Yeah. I'm right here." He smiled softly. "Answer my question." He demanded. It was a stark contrast to his expression.
Katsuki just pursed his lips, furrowing his brows like he barely understood what his boyfriend wanted from him. Denki only sighed, clicking his tongue. "Answer and I'll move."
"Fuck, yes," Katsuki admitted, voice all high pitched and breathy. It fell out of his mouth so quickly, like a criminal confession in an interrogation room.
Denki grinded his hips down again, a grin settling on his lips. Unlike Katsuki, Denki didn't bother trying to bite back moans. He sighed with relief, letting go of Katsuki's face in favor of gripping his shirt, balling it in his fists to help ground himself. Katsuki was so oversensitive. It was just some movement, not even that hard, but it lit his nerves on fire. He gasped.
"What were you thinking about all day?" Denki asked shakily, still grinding down.
"You," Katsuki gritted through his teeth, maintaining eye contact. "..I wanted--" He cut himself off with his own gasp, hips jerking, "I wanted you to-- to--" He stammered. He couldn't force it out. Especially not while looking Denki in the eyes. Denki's entire face was flushed, up to his ears. His tousled bangs framing his face, the stupid, stupid glasses on the bridge of his nose. Amber eyes that fluttered shut every time he moved just right.
"To..?" Denki asked, voice shaking. "What did you want, Katsuki?"
The way Denki said his given name felt world-shattering. It was almost always "Kacchan", or "Kats", or some dumb nickname he came up with. But his given name was something else. It was whined, his breath hitched, but he still made sure to say it with such reverence, with each syllable rolling off his tongue, Ka-tsu-ki, like it was an honor to say it. Like he would do anything he wanted.
"I wanted-- I wanted you to give me head," He broke eye contact, burying his face in Denki's shoulder. Their uniforms were sticking to their skin at this point, but neither seemed to care.
A quiet sigh was punched from Denki. He brought a hand to twist into ashy blond hair. "With the glasses on?" He asked quietly, like he was actually intending on doing it. Katsuki nodded frantically. "..Where?" He asked, voice shaking.
"..Floor," Katsuki's already meek sounding voice was muffled by the fabric of Denki's shirt. Katsuki could feel Denki nod.
"..I can do that," He murmured quietly. It was a promise. Katsuki felt his heartbeat spike. Denki would give him head. Katsuki's immediately let up on his grip, his arms resting at his sides now. Denki got off of him, fingers fumbling to undo his own tie and shirt, but Katsuki was all too eager, so he pushed Denki's hands away and practically yanked his tie off, unbuttoning his shirt, roughly pushing his hands under the fabric to get it off of him.
It made Denki shudder. He could be so aggressive sometimes, even when their power dynamic was well established. "Eager, huh?"
"Shut up," Katsuki spat, too occupied with rubbing the warmth back into Denki's body, biting down on his clavicle. The fucker really shouldn't have changed his costume shirt to show more of his shoulders, but fortunately that was not Katsuki's problem. Denki could fumble with his concealer all fucking morning for all Katsuki cared. He absolutely reveled in the way Denki tilted his head to the side just a little bit. "God, get on the floor,"
"Ask nicely."
It made his heartrate spike again. Denki's voice was a quiet little thing, almost whiny, wavering, but it had the same effect on Katsuki as it would've if he'd said it with full confidence.
He breathed out through his nose quietly, "..Please." He said, pressing a gentle kiss to the bite mark on his shoulder.
"Please, what?" Denki asked. Katsuki pulled away to see his face. God, was it flushed. He looked wrecked. He probably was.
"Please can you just- Can you get on the floor," He stammered. Practically begging at this point. He watched the grin on Denki's face grow. "Please." He repeated, shakier this time. Almost frantic.
"Sure I can.. Just relax, Kats." Denki pushes himself up and off the bed, sitting down on the floor, peeking up at Katsuki through his glasses. The sight made Katsuki's dick throb. Holy shit.
It did more for him than he thought it would. He wasn't even doing anything, just sitting there, looking up at him. Maybe it was the fact that Denki was just hot in general. But he never felt this.. Ruined. And Denki has been in this position a million times at this point.
Katsuki almost wanted to look away, but he couldn't do it for the life of him. Denki started moving. His hand went up to unbuckle his pants, unclasping the belt, not bothering to pull it all the way off. He undid the buttons with shaky hands, pulling the zipper down. Katsuki felt mesmerized. Denki's gaze was no longer meeting his, but just watching him do all this, with his eyes focused, fixed to his clothed dick, it shot heat straight to his core.
"F-Fuck," Katsuki whimpered when Denki's hand brushed up against his boxers. He could see a small little smile grow on his lips, but he didn't lose focus. He tapped his hip, and Katsuki lifted them embarrassingly quickly, like a trained dog.
Denki hummed, pulling them down to his knees. They pooled onto the floor, and Katsuki kicked them off, careful not to hit Denki in the process. Now he was left in just his boxers and his school shirt. His tie had basically come undone at this point, but Katsuki didn't bother removing it entirely.
Katsuki was getting desperate. Denki wasn't doing anything, just staring- He begged, god damn it, "Do you need an invitation?" Katsuki tried to sound annoyed, but his voice cracked.
Denki shook his head, licking his lips. "If you're gonna be snarky then maybe I shouldn't be doing this for you." He sighed hopelessly, pulling away to stand up. It made Katsuki's heart jump.
"No- Shit, okay, you're right-" He said shakily, "I'm sorry, 'm sorry,"
Denki paused. Stared at him. Holy hell he was so pathetic. He was straight up whimpering at this point. He adjusted, sat back down on his knees. He placed a soothing hand on Katsuki's thigh. "Hey, it's okay, Kat," He muttered, pressing a kiss to his inner thigh. "We learn from our mistakes, yeah?" Katsuki just nodded along frantically. "Let's get this off," He tapped his hip again, and Katsuki lifted it to help Denki take his boxers off. The cold air of his dorm hit his dick and made him shudder. It was dripping pre, flushed at the tip. Denki whistled.
"You wanna fuck my mouth?" He asked, looking up at him through his stupidly long lashes. His chin turned upwards a tiny bit. Katsuki sighed shakily- Jesus Christ, Denki would be the death of him. He can't fathom how he just.. Says shit like that with no hint of shame or embarrassment.
He nodded all the same. "Okay, then." He said softly, going to take his dick in his mouth. Katsuki gripped his hair, holding him in place.
"H-hold on," He murmured. Firstly, he needed to prepare himself for this. His body felt like it was on fire, flushed all over. Secondly, "You-" He stuttered, "You tap me if you wanna stop."
Denki looked a little bit caught off guard. But then his expression melted. "Okay." He said quietly. Katsuki's grip on his hair loosened, and he inched closer. He kissed the tip, making Katsuki shudder. He sucked in air through his teeth. "Just relax, baby." Denki murmured, swiping his thumb over Katsuki's waist. He sighed shakily, forcing his muscles to relax. "There we go," Denki said soothingly. And then, finally, finally, he took him into his mouth.
His momentarily lax muscles immediately tensed back up again, something between a gasp and a moan getting caught in his throat. He just took the head, and it still felt like he just got hit with a bag of bricks in the best way possible. As Denki took him halfway, his glasses slipped down a little, and shakily, Katsuki reached down to push them back up. It made his stomach twist. It was such a simple thing, and yet, it felt so unbelievably hot. Denki was looking up at him to gauge his reaction, and he sighed out of his nose. He could feel the breath on his cock, and it drove him just a little bit crazier.
Denki took him to the three quarters mark before pausing to give himself a breather. He adjusted, holding Katsuki's waist, pulling him closer with some effort. His dick felt heavy on his tongue in the best way possible, throbbing in his mouth.
A few moments passed, and then Denki took him down to the base. Katsuki's heart pounded in anticipation- and then he could feel the cold hard plastic of Denki's glasses hit his navel, and it downright broke him. It sent him into fucking nirvana.
His gasp got caught in his throat and almost made him choke on his spit. Denki's eyes were closed contently, his cheeks hollowed out. "D-Denki," He moaned. It was so much better than anything he'd imagined. Anything his brain conjured up could not hold a fucking candle to reality. Denki stayed in place for a few moments. Katsuki twisted a rough, calloused hand into his boyfriends hair, fucking up his ponytail. He gripped tight enough to pull a small yelp from him, keeping him in place. As much as Katsuki wanted to be gentle, he couldn't. It took too much willpower to stop himself from fucking into the warmth of Denki's throat, and that was something Katsuki had none of at the moment. "'M sorry- Ah-" He apologized anyways. Denki's eyes watered, but he didn't seem to care about the roughness considering he was starting to suck in tandem with Katsuki's thrusts.
"Fuck, y-you feel so good-" Katsuki gasped, "I'm not gonna last like this-" He promptly moaned again, throwing his head back when Denki teased the tip with his tongue. His piercing made it feel all the more better. Denki went harder, took him deeper, like he wanted to make sure Katsuki really wouldn't last. Denki coughed on his dick, Katsuki could feel his throat contract onto it, it made his vision blur, go black for a moment. He never thought pleasure like this was even possible. Still, he wasn't particularly interested in having Denki's throw up on his cock, so he pulled him back just a little bit, forcing himself to find the resolve to do it. He didn't pull Denki off completely, but he wasn't deepthroating him now. Katsuki let go of his hair to wipe the sweat on his face, and his ponytail fell out completely, hair cascading down to his shoulders.
Katsuki reached back down, sighing shakily through his teeth. Denki hadn't continued to move yet, just keeping his mouth on his dick, still and unmoving, heavy in his mouth. He plucked the hair tie loosely stuck in his hair, then held it up into a half-assed little ponytail, making sure to grab his bangs too, tying it up for him so his fringe didn't get in the way.
Denki's eyes were glued to him, his glasses crooked on his face. Katsuki had a wild grin on his face, teeth glaring at him. His canines were so defined, sometimes Denki wanted to stick his hand into his mouth.. His face flushed pink, sweat dripping down his temple. He looked almost feral. If the gentle way he bunched his hair up and tied it didn't shoot heat to his core, then the expression on his face definitely did. And it just motivated Denki to hollow his cheeks out, mind his teeth, and take him back down again. He didn't care if he gagged that much. The noise Katsuki made when he took him to the base and his glasses hit his navel again was downright guttural. Denki was making eye contact all throughout, breathing through his nose. He could barely fit the fucking air down his windpipe, Katsuki was so deep in his throat.
He pulled off, bringing a hand up to hold him at the base. Katsuki's thighs tensed, and he threw his legs over Denki's shoulder, pulling him closer with them. Denki kissed down from the tip to where his hand held his dick, it was so gentle, too much but not enough all at the same time. It drove Katsuki insane. And then Denki spat. Fucking spat.
"Hah-" Katsuki pulled on Denki's hair, purely by instinct. Denki was a mess. Panting, flushed, spit dribbling down his chin, a dazed sort of look in his eyes as he practically worshipped his cock. Denki licked a stripe following the vein that ended right at the tip before taking him back into his mouth, pumping the base where he couldn't quite reach with his mouth. Denki's teeth gently scraped his dick, where he usually made sure not to let them touch at all, but this was intentional. "Aah-- Denki!- Fuck, mind your god damn teeth--!" He hissed. He could feel Denki's lips form something resembling a smirk on his dick before he pulled back. He looked up at him properly this time, head turned back a bit.
"You love it," His voice was ruined. It was so hoarse it was unrecognizable. Katsuki stared at the choker on Denki's neck, stupid black velvet adorning his throat that looked so egregiously desirable. He wondered if maybe Denki liked the feeling of being strangled just a little as he watched it press tight to his Adam's apple. Denki flashed his smile at him, so stupidly cute. Even when he was using his teeth, he made sure never to let his sharper fangs poke him.
"Fffuck..." Katsuki stammered shakily, it sounded almost broken. Denki's voice was so destroyed. It drove him even deeper into insanity, and he needed him back on his cock or else he would literally fucking die. He gripped his blond hair tighter, guiding him back. Denki immediately went back to bobbing his head.
It was so messy, there was a pool of spit and pre on the sheets, but Katsuki could care less about his damn mattress right now. They built their rhythm back, and Denki seemed motivated as ever to deepthroat him again, removing his hand and taking him all the way. Katsuki started fucking into his mouth with short little thrusts that drew small yelps out of Denki each time. His grip on his hair tightened involuntarily, hands searching for a crutch, an anchor, something to keep him grounded in reality. His knuckles went white, one hand gripping the sheets, bunching them so tight his hand shook, the other buried deep in the silky blond hair of his boyfriend.
The coil in his stomach was building, he started moaning more and more frequently, fucking harder and harder, deep as he could go, and the best part was that Denki let him. Even though he couldn't breathe, even though his throat and jaw were surely sore, even though the grip on his hair was probably nothing short of searing, he kept going, making sure to use his tongue and tease the tip just right with his piercing.
"Shit-" Katsuki gasped, "Denki- Don't stop- Don't you dare stop--" He managed in between his pants. The glasses were barely even on his nose at this point, crooked and fucking foggy. They hit Katsuki's stomach with each harsh thrust, it felt so strangely gratifying each time, like they were urging him to go harder. Denki was still letting out little gasps with each thrust, which only added to it all. Katsuki threw his head back with a cry, "Hnnhh, shit, it's so good!-- It's- Hah!--"
And then the coil snapped. Katsuki let out some sort of strangled noise, keeping Denki on his dick as he came down his throat. Katsuki's vision went fucking white. He nearly fell on his back, only catching him with his arm which had been supporting him this entire time at the last second.
He let up on his grip in Denki's hair a few moments later, and he pulled off of him, coughing and panting. His hair was disheveled, the shitty ponytail Katsuki made for him already half undone. His fringe fell out of it, framing his face perfectly, sticking to his sweaty cheeks.
Denki was panting like a man who'd been suffocated to the brink of death, still sitting on the floor. Katsuki sighed shakily, letting himself fall to his back and his legs drop from his boyfriend's shoulders. The world spun around him a little, so he brought his arm to cover his eyes. That was definitely the most intense orgasm he'd ever had. Katsuki felt the weight of Denki's hand pushing himself to stand up on the mattress, and he soon dropped right next to him. Katsuki turned to his side to face Denki, who was shaking a little bit. He looked.. Spacey. Still panting, coughing occasionally.
His dick must hurt like hell, Katsuki mused to himself. He unzipped Denki's pants, not bothering to pull them down, shoving his hand down his boxers, his other wrapped around his waist to keep him in place.
"Fuck!" Denki almost shouted, hips canting up into his touch, keening. His voice cracked, sounding even more ruined than before. Denki sighed all shaky, hiding his face in the crook of Katsuki's neck. Katsuki thumbed at the tip, sliding down to give firm little pumps. He didn't need any lube, Denki's precum was doing all the work slicking him up anyways. Katsuki kissed his clavicle, sliding his free hand to rest on his lower back.
Shit, he was so fucking hot. If Katsuki wasn't quite literally just milked for all he was worth, he would've gotten hard again. He brought his hand up to tug at the hair tie keeping his hair up out, ruffling his hair, as if he could even fix it with how disheveled he was. "Kats- Nnh, Kats-!" He cried, all the while Katsuki left kisses on his neck, his shoulder, his clavicle, then moved up to his jaw, the little spot behind his ear. He pushed his hair out of the way and kissed there again, Denki pressing his face into the sheets, eyes squeezed shut, mouth seemingly unable to close. He was so, so beautiful. Katsuki reached up to pull the glasses off his face, there was no way they were comfortable to wear right now. Katsuki kept his pace,
"Say my name, Denki." He muttered. He had to hear it. Had to hear it like this, when Denki's voice was fucked, and he was about to make a mess all over his hand.
"Katsuki! Ah- Katsuki, K--Nhh," He gasped, holding onto his boyfriend for dear life, clinging to his arm. Katsuki kissed him sloppily, hungrily swallowing his moans. Denki could barely even reciprocate.
"That's it." Katsuki said, gripping harder. Not tight, but firm. Denki's hips jerked at it, "Atta fuckin' boy," Katsuki grunted, "C'mon, show me how you cum."
Denki let out some sort of sob at that. Katsuki could feel the sparks flying, buzzing in his skin where Denki gripped. "Mind the sparks, Denks,"
Denki instinctively pulled away, afraid of hurting him. "Hands on my shoulders." Katsuki ordered, and now it was Denki's turn to be the trained dog, arms wrapping around his neck. "You can do it. C'mon, firefly."
The pet name was the catalyst. Denki's cum spilled over Katsuki's hands, coating his boxers. He shook, both from the intensity and the effort of not turning Katsuki into a power bank right then and there. He gasped his name, and Katsuki kept going until he was sure Denki had nothing left to give, despite the pain in his wrist.
Denki's cheeks were flushed, his eyes closed shut, arms still wrapped around his neck, head tucked in the crook of his neck. Katsuki pulled his hand out of his boxers, wrapping his arm around Denki, careful not to get any of his cum on him. They laid there in silence for a few moments.
"That was.." Katsuki said quietly. "..Insane." He settled on that, even though insane wouldn't cut it. No word could accurately describe that orgasm. Denki's eyes fluttered open, his soft amber meeting Katsuki's intense carmine. He leaned in and kissed him softly without a word.
It wasn't intense. It was a simple little thing, but it was full of all the love in the world. Denki pulled away from it with a toothy grin.
"So.. Do you think I'll need to get the contacts?"
"Tch, shut up."
