You Make My Temperature Rise

Summary:

“You know I ain’t one to spout bullshit, so I’ll just be blunt - you wanna fuck around, I’m down for it.”

Shoto stared at him in shock. Bakugo? Interested in - that? With him? Was he joking? Was this some bizarre prank or a way to make fun of him, or -

Katsuki flicked Shoto’s forehead. “I can see the equations floating above your head, dumbass. It ain’t that complicated. I’m hot, you’re hot, we’re both pro heroes with zero time for romance shit, so if you’re into it, we should fuck. Simple as that.”

Or where an old friend and current rival awakens a side of Todoroki he never knew existed.

Notes:

I once said I’d never write smut involving Todoroki and also that Todobaku was meh... and now here I am 🥴 Anyway this will tie into my other fic Karma’s a Bitch but it’s also 100% a standalone oneshot. Hope you all like!

Work Text:

It was late at night and Shoto was tired as hell. It had been a long week at work but he had the next two days off, and now that he was freshly showered and settled in at home, he was ready to hit the sheets and not move for a good 12 hours (at least). 

 

Unfortunately, a sudden angry and violent knocking at his door threw a wrench into his plans. Sighing and quickly slipping on a pair of gray sweats, Shoto left the bathroom and made his way to the door and hoped he was wrong about his immediate assumption as to who was on the other side. 

 

He opened the door and barely stifled a sigh. His instincts were, regrettably, as sharp as ever. 

 

“Bakugo, it’s 11:30 at night. What do you want?”

 

“Shut up, half and half bastard,” Katsuki snarled back, though not before giving the half naked Shoto a once-over. He didn’t think much of it - Katsuki was probably just not expecting him to answer like that. “I’m here to fuckin’ talk.”

 

“Can it wait until tomorrow? Or better yet, two days from now when I’m back at work?”

 

“Fuck no, and fuck you,” Katsuki spat, and Shoto groaned and shoved the door open all the way. 

 

“Whatever. Just make it fast. I’ve had a long week and I need to rest.”

 

After Katsuki breezed past him, smelling like sugar and smoke as always, Shoto closed the door and then grunted in surprise when Katsuki immediately grabbed him by the shoulders, spun him around, and slammed him against the door. 

 

“Don’t worry, this won’t take long,” Katsuki grinned, and Shoto froze at the unexpected close contact. They were roughly the same height, so Shoto didn’t have to look up as Katsuki leaned a forearm against the door and went on, “I’m just here to make sure that you haven’t been fucking up on purpose lately.”

 

Shoto squinted. “What?”

 

“You were on track to hit number one by the start of the year,” Katsuki explained, leaning even closer and making Shoto’s discomfort levels skyrocket. “But here we are in November, and I’m still number one and you’re about to drop down to third or fourth.”

 

Shoto swallowed, wondering why his heart was racing. He wasn’t afraid of Katsuki, and he couldn’t think of any other reason for such a physical reaction. “And that’s a problem for you how?”

 

“Because,” Katsuki hissed, “number one doesn’t mean shit to me if it’s only mine by default. If you’re just letting your stats drop so you don’t have to deal with the pressure and all that shit, I’ll kill you.”

 

“Oh. No, that’s not what’s happening,” Shoto replied, head feeling a little clearer now that he fully understood. “To be honest, I’m having a harder time adjusting to running my own agency than I expected. I’m still figuring out how to balance it all, so that’s why my numbers are suffering.”

 

Katsuki studied him for a moment, clearly searching for any hint of dishonesty, before seemingly accepting that explanation. “Yeah, shit’s hard. Your old man should have prepared you for that.”

 

Shoto let out a harsh laugh. “He tried, in his own way. But his entire life was hero work, and I’m not interested in that being the extent of my existence.”

 

Katsuki grunted lowly, eyes softening as his expression became almost empathetic. “Yeah. We can agree there, at least.”

 

A beat of silence passed, and Shoto swallowed before awkwardly muttering, “Um… can you… you’re still pinning me to the door.”

 

Katsuki eyed him as if Shoto had just declared breaking news - the sky is blue! “Yeah, what about it?”

 

“... Can you stop?”

 

“Why? Is it making you uncomfortable?”

 

Shoto blinked. This was the weirdest conversation he’d ever had with Katsuki. “Yes, obviously.”

 

Katsuki tilted his head. “You sure? Because the second I slammed you against this door, I watched your eyes dilate and your cheeks get all red. Even saw a little bit of steam in your breath. So I’m kinda gettin’ the feeling that you’re into this.”

 

Shoto’s brain shut down. “Into - what? Why would I be - what -“

 

Katsuki shrugged casually, inching a little closer and letting his red eyes dip down and slowly roam over the man in front of him. “Give me a break, Todoroki - I’m hot as fuck. A lot of people would kill to be in your position right now.”

 

Shoto rolled his eyes, even as his heartbeat did something weird and probably medically concerning. “So humble.”

 

“S’the truth. You know I ain’t one to spout bullshit, so I’ll just be blunt - you wanna fuck around, I’m down for it.”

 

Shoto stared at him in shock. Bakugo? Interested in - that? With him? Was he joking? Was this some bizarre prank or a way to make fun of him, or - 

 

Katsuki flicked Shoto’s forehead. “I can see the equations floating above your head, dumbass. It ain’t that complicated. I’m hot, you’re hot, we’re both pro heroes with zero time for romance shit, so if you’re into it, we should fuck. Simple as that.”

 

Katsuki had always been like that, blunt and honest and fearless, and it was one of the things Shoto liked most about him. What you saw was what you got with him, and while they had never been particularly buddy-buddy, Shoto appreciated him and his company and enjoyed competing with him. But did he like Katsuki like that? He’d never considered it before, but…  

 

Katsuki was right - he was hot as fuck, Shoto had to admit. Tall and ripped with arms that shouldn’t have been legal, Katsuki in his 20s put Katsuki in his teens to shame. Shoto hadn’t known that he was into guys until this very moment, but he’d been told multiple times in the past that he wasn’t very observant with those sorts of things. Oh well. 

 

Shoto met Katsuki’s gaze, feeling a rush of almost giddy anxiety pass through him as he asked, “No strings, right?”

 

Katsuki barked a laugh. “You really gotta ask me that? ‘Course no strings, fuck. I don’t wanna date you, but I wouldn’t mind fucking your tight little ass.”

 

Inside, Shoto’s guts performed truly impressive acrobatics. On the outside, he narrowed his eyes and retorted, “Who says you’d be the one on top?”

 

In response, Katsuki grinned savagely. “ Ohh, a power struggle, huh? This is gonna be fuckin’ fun.”

 

“Not if you don’t shut up and do something. Unless you’re all talk.”

 

Katsuki’s eyes flashed ruby red and dangerous. “Oh, fuck you,” he growled before smashing his lips against Shoto’s in a kiss that was more a declaration of war than an expression of affection. It was hard and ruthless and everything Shoto had expected from him, and it set his body on fire in a way he hadn’t felt in a long time. 

 

Yeah, maybe this was a good idea after all. 

 

Grabbing firm biceps and breaking the kiss, Shoto flipped them around and had Katsuki against the door as they each leaned in and met halfway in a softer, deeper kiss. This one made Shoto nearly moan into the other man’s mouth, and he quickly realized that the more he got, the more he would want. Now that the match had been lit, he needed it to burn. 

 

Strong hands gripped Shoto’s hips before slipping around to his ass and squeezing hard through his pants, making Shoto gasp and break the kiss. They stared at each other through half-lidded eyes, Katsuki grinning and kneading firm muscles as he slipped a thigh between Shoto’s legs and rocked against unmistakable hardness. “Gettin’ off on this, huh?”

 

Shoto groaned, rocking against that thigh despite himself, chasing the little sparks of pleasure that raced up his spine. “Do you ever shut up?”

 

Nipping under his ear, Katsuki chuckled darkly. “Put your cock in my mouth and find out.”

 

Shoto froze, eyes widening fractionally and heat creeping up his body - literally. Feeling suddenly overheated, he parted his lips and tilted his head to the side as he let out a shuddering, steamy breath. Katsuki watched as the hot little wisps left his mouth, then cursed a low fuck that’s hot and dropped to his knees, just like that.

 

Feeling like this was moving way too fast and not fast enough at the same time, Shoto looked down and watched as Katsuki yanked his sweatpants down with little preamble, visibly swallowing as Shoto’s cock bobbed free and almost smacked him in the face. Katsuki blinked a few times in surprise - Shoto wondered if Katsuki expected him to be smaller or something - but then there was a warm hand wrapped around him, pumping slowly, and Shoto closed his eyes and lost his train of thought. God it had been way too long since anyone had touched him like this. 

 

“Hey,” a low, demanding voice called from below, “eyes on me, bastard.”

 

Shoto opened his eyes and looked down, then nearly lost it almost immediately as he watched Katsuki look him dead in the eye and lick a long, filthy line from base to tip.

 

Shit,” Shoto hissed, bracing both hands against the door and watching hungrily as Katsuki smirked before wrapping his lips around the tip and sucking while his hand worked the rest. The sight was so unexpectedly hot - who knew Bakugo was capable of such sensuality? - and Shoto had to swallow hard and force his body temperature to stay under control. 

 

Pulling off with a dirty little pop, Katsuki chuckled and said, “I always wondered if your dick was hot or cold. But the left side is a little hotter than normal and the right is a little cooler - fuckin’ hilarious.”

 

Gritting his teeth, Shoto hissed, “Are you gonna sit there and laugh at it or are you gonna suck on it?”

 

Katsuki’s brow lifted at the sass. “Pretty ballsy of you to boss around the number one hero while he’s on his knees for you. Someone oughta teach you some manners.”

 

“How about later, when I’m not about to lose control and set this whole building on fire?”

 

“So desperate,” Katsuki murmured, still stroking him and lips still close enough for his warm breath to tease. “Been that long since you got laid?”

 

Shoto clenched his jaw, wishing Katsuki didn’t always have to be such an ass all the time. “Not really any of your business.”

 

“Maybe not, but I’m kinda curious since you seem so pent up and -“

 

Patience snapping, Shoto grabbed Katsuki’s hair and pulled hard, yanking his head back and glaring into surprised red eyes. “Bakugo,” he said lowly, harshly, “shut the hell up and suck me off.”

 

Katsuki seemed to like that. He stared up at Shoto in silence, cheeks flushing as he licked his lips and then opened his mouth in silent invitation. Shoto took himself in his free hand and guided himself to those lips, pushing past them and into the warmth of that sarcastic mouth once more. 

 

“Good boy.”

 

Katsuki’s eyes flashed in anger, and he grabbed Shoto’s hand in his hair and smacked it away. Shoto didn’t mind, placing it back on the door and shuddering as Katsuki finally, finally got back to work. And damn, he was good with his mouth. 

 

Clearly experienced and seemingly rather enjoying himself, Katsuki threw himself into his task and rapidly had Shoto fighting to keep his eyes open, not wanting to miss a second of the tantalizing sight of his cock disappearing into the hero’s mouth over and over again. Katsuki’s hands were on Shoto’s ass, gripping and pulling him in deeper with every swallow, and Shoto’s short nails scratched against the door as he panted, “I’m not gonna last.”

 

He expected Katsuki to back off. Instead he started moving faster, sucking harder, all but choking on him, and Shoto let out a shocked cry as he went rigid and filled the other man’s mouth. He couldn’t have stopped himself if he’d tried, the orgasm tearing through him like lightning and leaving him panting and weak-kneed by the time it was over. He was about to slump down to the floor when Katsuki stood up and pulled him close, supporting his weight and invading his mouth with a filthy kiss. 

 

Shivering faintly at the taste of himself on the other man’s tongue, Shoto broke the kiss and sighed, eyes closed as he focused on lowering his too-hot temperature and letting his right side cool him off. “You shouldn’t have let me come so early.”

 

“You’re so pent up, I bet I can get at least two more rounds out of you before you tap out.”

 

Shoto opened his eyes and eyed Katsuki skeptically. “I can’t tell if that’s a challenge or just your ego talking.”

 

“Guess you’ll find out soon enough,” Katsuki grinned. “So. Gonna let me fuck that ass or what?”

 

Shoto flushed despite his cooler current temp. “Would my mouth not be enough to satisfy you?”

 

Katsuki hummed, his palms finding Shoto’s ass again and fingers digging in pleasantly as he pretended to think it over. “It ain’t really about that. You blow me, only I get off. We fuck, we both do.”

 

That did sound more efficient, but… 

 

“Does it actually feel good? For the receiver?”

 

Katsuki stilled, staring at him in genuine surprise for a moment before a wide, dangerous grin broke out on his face. “Seriously? Don’t tell me this is your first time with another guy.” At Shoto’s blank expression, Katsuki stifled a laugh. “ Holy shit, this is your first time with another guy.”

 

“It’s rude to laugh at other people’s inexperience,” Shoto deadpanned. 

 

“Yeah, yeah, I’m just surprised,” Katsuki shrugged, feeling Shoto up once more. “But to answer your question - fuck yeah it feels good. It feels really good. And lucky for you, I’m the best damn top in this whole goddamn country.”

 

“... There’s no possible way you could know how your skill ranks against every single citizen of Japan, let alone -“

 

“Nah, fuck that,” Katsuki interrupted, bending down and then grabbing Shoto like he weighed nothing, tossing him over his shoulder like a sack of potatoes. “I am the best, and I’m gonna prove it.”

 

Shoto sighed, accepting the manhandling as Katsuki walked them to the bedroom. “I haven’t consented to this yet.”

 

“How about we make a deal?”

 

“I’m listening.”

 

Now in the bedroom, Katsuki tossed Shoto on the nearly-made bed and then got to work finally shedding his own clothes. “Let me show you how good it can feel,” he said, pulling his shirt over his head and displaying hard muscles, faded scars, and abs that could cut someone. “I can finger you or eat you out or both, whatever you want. If you like it - and you will - then you can decide if you wanna fuck or not. If you don’t like it - which isn’t gonna fuckin’ happen, because I’m awesome - then you can fuck me. Deal?”

 

Naked after having kicked off his sweatpants, Shoto leaned back on the bed and watched Katsuki shed his jeans, mulling over the idea. Katsuki was gloriously and shamelessly naked by the time Shoto carefully furrowed his brows and cocked his head to the side, asking, “Eat me out? I’m not a woman.”

 

Katsuki’s haughty expression fell into absolute disbelief. “Okay, what the fuck. Don’t tell me you don’t know what that is.”

 

Shoto blinked. “What what is?”

 

Katsuki’s left eye twitched. Shoto continued to stare at him with big, innocent eyes, and eventually Katsuki’s eyes narrowed. “Wait a minute. You’re fucking with me, aren’t you?”

 

Shoto let the grin he’d been suppressing finally break free. “No, not at all. Please tell me in detail what this sex act is.”

 

“I fuckin’ hate you,” Katsuki growled, kneeling on the bed and invading his space once again as Shoto let out a quiet laugh. 

 

“Do you sleep with everyone you hate?” 

 

“Sometimes,” Katsuki grinned before kissing him, and Shoto let himself smile into the kiss, too. Doing this with a friend, one whom he trusted… this was nice, he had to admit. There wasn’t any pressure or messy feelings to complicate matters, and it was unexpectedly freeing. 

 

It was also a distinctly new experience, touching a man rather than a woman. Katsuki was all hard edges and muscles, so different from the soft curves and sweetness Shoto had known before, but Shoto didn’t mind the differences. In fact, the more that they kissed and touched, Shoto’s hands exploring miles of bare skin and roaming curiously all over Katsuki, he decided he actually rather liked this. It was a good sort of different. 

 

“So,” Katsuki panted against Shoto’s open mouth after a few particularly intense kisses, grinning as he rocked their hips together and gradually stirred Shoto’s dick back to life. “What’s the verdict?”

 

Shoto swallowed, exhaling lowly and thinking that just doing this - rocking and rubbing together, until they both lost it - wouldn’t be so bad. But on the other hand… he was pretty curious, and he’d come this far. Might as well take it the rest of the way. 

 

“Your fingers,” he breathed, meeting Katsuki’s gaze. “Use your fingers.”

 

Katsuki smirked devilishly and leaned down for a fast, sloppy kiss, then promised, “I’m gonna make you feel so damn good, IcyHot, you have no idea.”

 

Shoto shivered with anticipation but replied, “That almost sounds like a threat.”

 

That smirk grew even more devious. “That’s ‘cause it is. Where the fuck’s your lube?”

 

“Top drawer,” Shoto replied, gesturing carelessly to his nightstand. He watched at Katsuki leaned over and rustled through the contents, and while Shoto waited, he let a few of his right hand fingertips frost over before reaching up and casually sliding them over Katsuki’s side. 

 

Naturally, Katsuki screeched in outrage and nearly fell out of the bed before pouncing back on a grinning Shoto and screaming, “What the hell, you bastard?! That was fucking cold, what the fuck’s wrong with you?!”

 

Shoto merely smiled and raised his arms over his head. “Sorry. You’re fun to tease, that’s all.” Katsuki narrowed his eyes, but Shoto licked his lips and looked up at him through his lashes as he let his legs spread open in invitation. “Touch me, Bakugo.”

 

Katsuki’s cheeks visibly heated, his eyes widening a little at the display. “... You’re lucky you’re hot, you fucker. And if we’re about to fuck, call me by my given name.”

 

They’d been friends for years, and yet Shoto didn’t know if he’d ever called him by his first name before. “Katsuki,” he replied lowly, testing out the name on his tongue, and Katsuki seemed to really like it. 

 

“Fuck yeah,” he groaned before popping open the cap on the lube and sliding down between Shoto’s legs. He pulled one thigh over his shoulder and pushed the other to open him wider, and while Shoto felt uncomfortably exposed, the feeling faded once Katsuki took his half-hard cock back into his mouth and coaxed him back to full hardness. 

 

“Shit, you’re good at that,” Shoto sighed, hearing and feeling Katsuki’s responding chuckle. He closed his eyes and was losing himself in the warm sensations until a slick finger brushing somewhere new jolted him back to reality. 

 

He wasn’t nervous about trying this, which is why he stayed calm and didn’t tense up too badly as that first finger pressed gently inside. Rather than being fearful, he was simply still skeptical that it was going to be worth all the effort, and when the careful in and out motions of the single finger mostly just felt strange more than anything else, he figured this would prove to be something he didn’t like. Still, he kept his mouth shut and trusted Katsuki to do his best, enjoying the way Katsuki distracted him by sucking little bruises into his hipbone and occasionally taking his cock back into his mouth, keeping him hard and wanting. 

 

The second finger brought with it a sting and real discomfort, but Shoto only winced and kept his breathing even, not letting himself tense up or otherwise fight the intrusion. Katsuki raised a brow at him and observed, “Damn, for this being your first time, you’re taking my fingers so well. Staying so nice and relaxed for me.”

 

Flushing a little under the rare praise, Shoto squirmed a little against the gentle thrusting fingers and replied, “So far I’m not seeing what all the fuss is about.”

 

“Be patient, half and half. We’ll get there.” Then Katsuki was sucking him off again, and Shoto gasped and dropped his head back under the onslaught of warring sensations. It was a lot to process, especially as Katsuki’s fingers started going deeper, faster, the pain fading away fairly quickly and being replaced with that strange neutrality from before. Shoto was mere moments away from deciding against the whole thing when Katsuki twisted his wrists and curled his fingers and made lightning shoot through his entire body. 

 

“W-what the fuck,” Shoto gasped, not realizing how he’d arched off the bed until his back hit the mattress. He looked down and found Katsuki smirking proudly up at him, and rather than give him a chance to catch his breath, Katsuki’s fingers sped up and utterly tormented that spot he’d discovered. “Is that -“

 

“Uh huh,” Katsuki grinned, watching hungrily as Shoto’s hands clenched in the sheets and his cock twitched against his belly. “Feels good, right?”

 

“Why didn’t you do this from the start?” Shoto asked, his voice drifting off into a moan. “ Shit.”

 

“Cause you woulda already come again by now,” Katsuki explained, slipping a third finger in amid the haze of pleasure and oh, that was a lot. “And I want you to come with me inside you.”

 

Shuddering at each new wave of pleasure that shot through him, Shoto found himself imagining it - Katsuki deep inside of him, their bodies flush, lips locked in furious kisses as that same pleasure overtook him - and he gasped as the mere idea had his body overheating. And Katsuki noticed. 

 

“Fuck, you’re getting hotter,” he murmured, looking up and watching as Shoto reached down with his right hand and grabbed Katsuki’s hand to still it. He took a deep, calming breath, and his temperature returned to normal. 

 

“That’s enough,” Shoto decided. Katsuki removed his fingers and Shoto was surprised that he missed them once they were gone. Katsuki made to climb on top of him but Shoto pressed a palm to his chest, telling him, “I want to be on top.”

 

Shoto expected an argument but Katsuki simply raised a brow and then flopped on his back. “Sure, sweetheart, you can ride me.”

 

Shoto rolled his eyes as he followed and straddled the other man, settling himself on Katsuki’s hips and remarking, “Pet names sound weird coming out of your mouth.”

 

Katsuki’s hands were on Shoto’s ass, holding him open as Shoto reached back to hold his dick steady while he lined himself up with it. “You rather I call you something mean?”

 

Shoto considered that, letting out a long breath and relaxing his body as he began to slowly sink down. His brows furrowed - it was a lot to take, a lot more than a few fingers, but he wanted it so he pressed on - and his voice was strained as he replied, “How about my name?”

 

Katsuki let out a little grunt, his grip on Shoto tightening as he got halfway down. “Fuck, you’re tight… Shoto.”

 

He didn’t expect that to have the effect that it did. Shoto’s heart skipped more than one beat and his cock jumped as he suddenly slammed himself down to the hilt, both of them letting out cries of surprise and staring at each other as they panted softly. 

 

Katsuki grinned wickedly. “Like it when I say your name, huh, Shoto?” 

 

The same feeling happened again, and Shoto gritted his teeth and tried to roll his hips but it was too fast and too jerky, leading Katsuki to grip his hips and still him. 

 

“Hey, hey,” Katsuki murmured, sitting up and kissing Shoto’s lips. “Gotta pace yourself, all right? You’ll hurt yourself if you don’t.”

 

Shoto’s fingers dug into Katsuki’s shoulders, his body overheating again. He overcompensated this time as he tried to cool down, letting out a frosty exhale against Katsuki’s lips before muttering, “I need more.”

 

“M’gonna give you more, trust me,” Katsuki chuckled. Then his hands were back on Shoto’s hips, this time gently pushing and guiding, showing him how to move. “Fuck, you feel good. Just go slow while you’re getting the hang of it, all right?”

 

Shoto hummed, holding on tight and slowly, carefully lifting up and bringing himself back down, following the gentle rhythm that Katsuki was trying to set him to. “Never thought I’d hear the words ‘go slow’ from you, Katsuki.”

 

Katsuki chuckled, leaning down and kissing Shoto’s neck, licking a hot line up to his jaw. “What can I say, I’m full of surprises.”

 

Shoto groaned, one hand slipping to grip the spikes at the back of Katsuki’s head as he started moving a little faster, a little deeper, gaining confidence. He hadn’t yet figured out how to hit the spot that Katsuki had found so easily, but it still felt good and he didn’t even mind the little bruises and bite marks that Katsuki was littering across his neck and shoulder. He liked the rough but careful way Katsuki handled him, liked the way he made him feel. 

 

They stayed like that for awhile, Shoto in Katsuki’s lap, riding him and kissing him and working up a sweat, his thighs starting to shake before he would have liked. Katsuki noticed, and that was when he murmured c’mere and flipped them, laying Shoto on his back without slipping out of him. Shoto shot him a weak glare but Katsuki promised, “It’ll feel better this way, trust me.”

 

And Shoto did. 

 

After shoving a pillow under Shoto’s hips and rising up on his knees, both of Shoto’s legs hooked over his elbows, Katsuki started moving again and the difference was immediate and incredible . The spot that had eluded Shoto was now being slammed with each smooth, deep thrust of Katsuki’s hips, and Shoto let out a very undignified noise that had Katsuki laughing darkly. 

 

“That’s right, pretty boy,” he rasped, “make all those dirty noises for me. Bet everyone would be shocked if they saw you like this, huh? All spread open for me and moaning like a little slut, taking my cock like you were made for it.”

 

“Shut up and fuck me harder,” Shoto demanded lowly, deciding to turn up the heat literally and raise his body temp just enough to make Katsuki choke on nothing. It worked like a charm, and Shoto grinned as he watched Katsuki’s eyes go wide and his rhythm stutter. 

 

Holy shit,” Katsuki groaned, eyes rolling shut in bliss before opening and fiercely locking with Shoto’s own. “You’re burning up. That’s fuckin’ - God, that’s sexy as fuck, shit -“

 

And then Katsuki pounced on him, slamming their lips together and leaving Shoto’s legs to wrap around his hips as he started fucking him with abandon. Shoto moaned into his mouth in delight at the change, bringing his hands to Katsuki’s back and feeling the muscles work as he moved. Shoto quickly began to lose the ability to think, his entire world shrinking to just heat, pleasure, and Katsuki until the faint smell of burning fabric jolted him back to reality. 

 

“Fuck,” Katsuki hissed before yanking a hand away from where it had been planted on the bed and, evidently, burned a hand-shaped hole in the sheets. He wiped off the excess explosive sweat from his palm on another part of the bed and muttered, “Been a long time since I slipped like that, Shoto. You should be proud.”

 

Shoto looked at the singed sheet, then brought his gaze back to Katsuki and yanked him back down for a desperate kiss, his hips squirming against Katsuki’s. “I don’t care if you set my whole apartment on fire, just keep fucking going.

 

He punctuated those words with a sharp bite to Katsuki’s lower lip, and it seemed to snap what was left of the other man’s self control. Katsuki let out a roar and started fucking him widly, grabbing Shoto’s wrists and pinning them to the bed, and for the first time in his life, Shoto was able to truly let go completely and submit to someone else, letting Katsuki take control and drive them both towards ecstasy. 

 

It surprised Shoto how quickly his orgasm snuck up on him after that, and without a single touch to his cock that was trapped between their bellies. Without so much as a fraction of a warning, suddenly his body was seizing up and flooding with warmth and fire and pleasure that made his eyes roll back and his voice make the sort of breathless, helpless sounds he’d never thought himself capable of before. His entire reality eclipsed by perfect bliss, he was unaware of the way he unintentionally broke out in small flames all over the left side of his body, leaving a Shoto-shaped scar on the sheets as Katsuki watched in awe and, holding himself up just right to avoid the flames, came with a surprised shout of his own. 

 

Shoto didn’t know how long they laid there, a useless and entwined pile of limbs and heavy breaths, until Katsuki finally pulled himself out and then rolled over on his back with a groan. It was then that Shoto blinked his blurry eyes open and realized that he’d just gotten his brains fucked out of him - and that he’d loved it. 

 

He’d also completely ruined his sheets, which were still smoking from where he’d accidentally burned them, but oh well. He was overdue to buy new ones anyway. 

 

Beside him, Katsuki let out a low rumble of a chuckle. “Told you I’d make it good. Better be the last time you ever doubt me, you fucker.”

 

Shoto huffed a small laugh of his own. “I admit, I’m pleasantly surprised. I had no idea a cock up the ass would feel that good.”

 

Katsuki whistled. “Got a dirty mouth on you after all. But let me correct you there - not just any cock can do that. I told you I’m the best there is.”

 

Shoto grinned, closing his eyes and wondering just how many men Katsuki had slept with to acquire his experience and skill. His first thought was Kirishima, but Midoriya was also a possibility. Something to ponder later, in any case. 

 

For now, his eyes were refusing to open and the bone-deep exhaustion from earlier was rapidly settling back in, dragging him towards desperately needed sleep. He needed to clean up and change the sheets and see Katsuki out, but he was so tired. Maybe if he just… let his eyes rest for a moment, he’d be able to wrestle up the motivation to get up and… 

 

He startled awake - when had he fallen asleep? - when he felt a warm, wet towel sliding over his body. “Shhh, go back to sleep, IcyHot,” Katsuki whispered, looking rather tired himself in the dim light. 

 

Shoto hummed, letting out a deep breath and letting Katsuki clean him up, a little surprised by the gesture. “You didn’t have to do that.”

 

“Shut up,” Katsuki said lightly, pulling the comforter over Shoto when he was done. “I might be an asshole, but I know how to be a good lover.”

 

Shoto grinned, already feeling sleep begin to take him again. “Yeah, you do. Stay and we can do it again in the morning.”

 

The last thing Shoto heard was a faint chuckle followed by a quiet, “Deal.”
