Chapter Text
They held each other’s gaze for just a second before Bakugo leaned down and sealed his lips over Kaminari’s.
And Kaminari--bless his slutty, overwhelmed, relieved, dumbass little soul--moaned immediately. He didn’t even attempt to keep up with what the fuck was happening anymore. It was clearly beyond his brain’s ability to process. And besides, there were other, more urgent things keeping him preoccupied.
Like how hot and surprisingly soft Bakugo’s skin was and how hard his shoulders were and how his hand was back in his hair, pulling it again, but this time he was allowed to shiver and happily lose his mind over it, turning a little on the bed so he could angle himself better to lick along Bakugo’s bottom lip. Even the sound of shifting fabric somehow felt good. He vaguely wondered if this was some adrenaline high after feeling so much panic, but didn’t care enough to dwell on it.
Speaking of which.
“Please don’t hit me now,” Kaminari said against Bakugo’s lips.
Bakugo huffed out a laugh and pulled away from him, which would have been unacceptable, but then he grabbed the edge of Kaminari’s hoodie and asked if he could take it off.
He wanted Bakugo to take all his clothes off. Wanted Bakugo’s clothes gone, too. He wondered if he should say that, but he felt like he was very likely a LOT more turned on right now than Bakugo was. He shifted to help him pull the hoodie off, and then immediately lost his train of thought as the movement sent a jolt of arousal through him. He gasped, rocking his hips back and forth to see what it felt like.
That… definitely didn’t hurt anymore.
Bakugo watched, eyes raking over him in a way that felt almost physical. His palm smoothed along Kaminari’s torso and slipped under his rucked up shirt, stopping at his chest to push him backward into the mattress. He followed, leaning back in to kiss Kaminari again, just as stupidly good as it was the first time, but better now because Bakugo’s rough hand was touching his bare skin and he was climbing onto the bed to slot himself in between Kaminari’s thighs.
He figured he shouldn’t have been surprised that Bakugo was a good kisser. It seemed like he was good at everything. And the natural progression of that thought made Kaminari groan and draw his legs up on either side of Bakugo’s hips and squeeze.
It was literally impossible to stop rocking his hips now that he’d started (not that he’d tried), so when Bakugo trailed kisses down his jaw to lick and mouth at the skin under his ear, he was already panting. He tilted his head with a shaky breath, offering more of his neck.
“Still hurt?” Bakugo asked, smirking into Kaminari’s skin.
Kaminari hummed in response, barely registering the taunt. He dragged his fingertips over Bakugo’s sides, raking up the thin fabric of his tank top and tripping over it along the way. Every part of him was so thoroughly toned and Kaminari was extremely interested in touching it. His hand trailed down Bakugo’s back and arrived at his waistband.
Bakugo kissed him again, filthier than before and so satisfying Kaminari decided whatever reservation he had before about removing their clothes was no longer worth entertaining. He pushed up, urging Bakugo back, and was surprised when he went willingly and let Kaminari sit them both up.
“Can I take your clothes off?” he asked Bakugo impatiently, already pulling off his own rucked up shirt and dropping it on the floor.
“You don’t need to ask at this point, dumbass.”
Kaminari ignored his derision very easily, setting about pulling off his black tank top and feeling up all the newly exposed skin. He moved forward and kissed back into his mouth, moaning when he felt two fingers steal into his jeans and drag along the edge. They stopped at his fly.
“Please,” Kaminari whined, totally unsure whether it was intentional.
Bakugo undid the button and zipper, fingers brushing against his cock impassively. His other hand reached around Kaminari’s back and crept into his underwear.
Kaminari froze, realizing he had completely failed to consider the very violently bad reaction that Bakugo might have to the fluffy yellow tail attached to the plug.
Bakugo’s fingers reached it and paused for a moment, registering, before slowly feeling over it.
“Ho-ly shit, you kinky little fucker.”
Kaminari tried very hard not to nervously dig his fingernails into Bakugo’s shoulders.
Bakugo chuckled lowly and it was impossible to know whether that was a good or very fucking bad sign. His fingers trailed back to the base and pressed it in just a little. Kaminari gasped against his smirking lips, still too riddled with nerves to move.
But then Bakugo eased his hand out, snapped the elastic of his underwear and said
“Take these off.”
For a moment Kaminari was so preoccupied with grateful, horny relief that he went to pull them down right there before he realized that would be physically impossible. Bakugo helped him maneuver off the bed (since, you know, plug and all) and Kaminari unceremoniously pulled his jeans off with his underwear and kicked them toward his shirt, making a messy little pile on the floor.
Bakugo was looking at his legs when Kaminari turned back over to him.
“You really put on all that shit just to jerk off?” Bakugo’s voice sounded dry and it filled Kaminari with vicious delight.
He thanked Past Denki for choosing to put on knee highs and his choker for this (un)failed solo experiment.
“Doesn’t seem like you mind,” he smirked. He turned and shamelessly pulled one asscheek to the side to show Bakugo exactly where the tail connected to his body.
Very abruptly, Bakugo was standing, turning him back around and kissing him hard enough that it made Kaminari a little dizzy. He hummed into Bakugo’s mouth, gripping the back of his neck and hooking an enthusiastic finger into his sweatpants. He gratefully remembered that Bakugo already gave him permission and quickly set about peeling them the fuck off along with the other useless fabric underneath. He pushed Bakugo’s shoulders hard and urged him back onto the bed.
They scooted back until Bakugo was leaning against the wall. He briefly stopped them along the way, opening his bedside drawer and blindly grabbing a telltale bottle with such an absence of formality that Kaminari felt like he would literally become violent if he had to spend one more second not straddling his lap.
God, kissing Bakugo was delicious. It sent shivers over his skin in a way that made him check he wasn’t accidentally activating his quirk. He held the sides of Bakugo’s face, like he might do something devastating and irrational like try to pull away.
Bakugo slid a hand over Kaminari’s thigh while the other palmed his ass, pulling him around the plug and making him moan. His fingers trailed inward and traced around the stretched rim and Kaminari’s breath stuttered.
“You wanna take this out now?” he asked, tilting his head back to look at Kaminari.
Kaminari’s pleasantly addled brain cleared at the question. He met Bakugo’s gaze for a moment before turning and resting his forehead against the wall beside Bakugo’s head. He swallowed.
“It’s gonna hurt,” he said honestly, “in a, like, not sexy way.”
“Hmm,” Bakugo acknowledged, still passing his finger around the plug, which felt almost soothing now that they’d slowed down. Kaminari was pretty sure that couldn’t be the right word because literally nothing about Bakugo was soothing, but… close enough.
He did want Bakugo to take it out. Really, he did. But it was honestly kindof nerve wracking and he didn’t want to embarrass himself. It was one thing for Bakugo to know about it and another for him to see it.
He thought back to what Bakugo said when he’d been furious about the nonexistent “fucking bastard” who got him in this predicament. He leaned toward Bakugo’s ear.
“So you’re gonna fix me up after then?” Kaminari said quietly. His heart thumped.
Bakugo smirked, “Yeah, I’ll fix you up.”
He pressed the base of the plug in slowly and held it there and Kaminari’s breath snagged on an ~innocent~ little sound as his head dropped. He licked his lips and swallowed again.
“I’m serious though,” he rushed, anxiety speaking before embarrassment could shut it down, “Please be gentle.”
He tensed and waited for Bakugo to make fun of him for it, but it didn’t come.
Bakugo tipped them, guiding Kaminari until he was laying down. And even that was gentle and it made Kaminari’s nervous, overexcited heart
p a l p i t a t e.
Bakugo looked at him seriously, red eyes burning through Kaminari’s shaky attempt at calm.
“If it hurts, you tell me and I’ll stop.”
Kaminari swallowed again, feeling overly aware of how often he was doing it.
“Yeah?” Bakugo pressed.
“Yeah.”
Bakugo looked over his face for a second longer.
“Hang on,” he said, and got off the bed.
He returned with a towel and helped prop kaminari’s hips up. Kaminari couldn’t help but grin.
“What?” Bakugo asked, unamused.
“You really are gonna be gentle, huh?” Kaminari wiggled his hips a little.
Bakugo clicked his teeth, knocking Kaminari’s knees apart and urging them up.
“I’m gonna gently fuck you up, you blushing virgin little shit.”
Kaminari geared up to spout more unwise goading bullshit, but was interrupted by the Much More Interesting sound of a cap opening. He watched Bakugo spread lube over his fingers and settle between his legs again. Bakugo reached down between them. Kaminari didn’t realize he’d stopped grinning until Bakugo rolled his eyes and leaned forward.
“Breathe, Denki.”
He hadn’t realized he’d stopped breathing either.
Bakugo grumbled something rude and leaned down the rest of the way to kiss him. Which did seem to do a pretty good job of gently fucking him up, he had to admit.
Then he slipped his free hand into Kaminari’s hair and pulled. And at the same moment, the slick press of his fingers were easing deliberately over either side of the plug, massaging and relaxing the muscle in a way that felt surprisingly not embarrassing or painful at all and extremely damn good. His hand flew up to Bakugo’s hair, needing to hold onto something.
The tension left Kaminari’s body and he grinded against Bakugo’s hand. They kissed hard and Bakugo made a satisfied noise against Kaminari’s lips that threatened to make him short circuit.
Make that sound again, he thought, sane enough not to voice it. He reached in between them to wrap his hand around Bakugo’s cock, but the latter pinned his wrist to the pillow beside his head.
Kaminari pouted a little, but honestly... that was fine. If Bakugo wanted him to do nothing but take, then he could happily lay back and take.
He pulled Bakugo’s lip between his teeth as the latter pulled gently on the plug. He shifted it up and down before pushing it back in, pressing again. Kaminari moaned, absolutely filthy, head tilting back into the pillows and hand fisting tightly in Bakugo’s hair.
“Shit,” Bakugo said, sounding reverent.
He repeated the action and Kaminari desperately tried to hold back the next very loud noise that threatened to spill out of him, biting down hard on his lip.
Bakugo released his hold on Kaminari’s wrist. He put his thumb on Kaminari’s chin and coaxed his mouth open.
“Never seen you try so hard to keep your mouth shut, Sparky,” he sneered, “What, you don’t wanna share your thoughts with the class?”
Bakugo pulled again, the widest part of the plug stretching him almost painfully but not quite. And before Kaminari could consider how nervous the concept of “sharing with the class” actually made him, he was already making a sound close to a sob, looking up at Bakugo and feeling like he would probably do whatever he wanted if he kept touching him like this.
Then Bakugo was moving, taking Kaminari’s hand out of his hair and kissing down his chest and abs and Kaminari almost squirmed knowing what was about to happen.
Bakugo didn’t tease and Kaminari thought he would have to build him a fucking shrine for it in thanks. His hands were back in Bakugo’s hair immediately as the other licked a hot, wet line up the length of his cock.
“Oh fuck” he breathed out, unable to stop his hips from, just slightly, pushing up as Bakugo took the head into his mouth.
“Don’t come,” Bakugo said plainly, but the gravelly quality to it had Kaminari hissing trying not to do just that.
He pressed his head back into the pillow, unable to look anymore, hands leaving Bakugo’s hair to cover his eyes. And then his mouth, since he really was making too much damn noise and there was no other way to stop it.
Bakugo wasn’t even doing anything all that elaborate. Just sucking and licking at him, rhythmless, in a way that made every movement from the plug more and more delicious.
Kaminari’s hand flew to Bakugo’s shoulder when he took him all the way into his mouth. He was pulling steadily on the plug, bobbing his head and sucking as the widest part stretched Kaminari, who hissed and did not tell Bakugo to stop, because the pain was, at that moment, with Bakugo’s mouth around him, was one of the best fucking things he’d ever felt.
Bakugo pulled the plug out completely and Kaminari shoved him away, panting.
It seemed like Bakugo was about to say something, so Kaminari rushed to interrupt: “Don’t touch me,” holding out a hand to keep him away.
Bakugo closed his mouth, brows furrowing in something that looked like annoyance but Kaminari could tell was concern.
“I’m going to come if you touch me,” Kaminari offered, feeling mildly guilty.
Bakugo tossed the plug carelessly. The thud as it hit the floor was so loud they both flinched. Kaminari very purposefully did not look over at it.
“You ok?” Bakugo asked, wiping his mouth with the back of his hand.
“Yeah,” Kaminari said, smiling. He shifted his hips a little to see if it would hurt, but it just felt tender. In a definitely not unpleasant way.
Empty too though.
“Yeah,” he said again once he’d caught his breath. He dragged his eyes over Bakugo’s body and sat up, still careful not to move too quickly. “You can touch me now,” he said, wrapping his arms around Bakugou’s neck in a way that would have felt too romantic if he didn’t feel so much like he bonelessly needed to. Bakugo tolerated it easily, met Kaminari in a kiss and let it be syrupy.
Kaminari could taste himself, just barely, on Bakugo’s tongue and it made him shudder. Made him want to know what Bakugo tasted like. He trailed his fingers down the valley of Bakugo’s abs and stilled, mindful of Bakugo pulling his hand away when he’d reached for him before.
“Can I touch you now?” Kaminari asked.
“Yeah,” Bakugo said, rutting forward so his cock brushed against Kaminari’s fingers.
“Be gentle,” he teased, biting Kaminari’s earlobe.
Kaminari zapped him.
“Hey, I was fucking NICE to you, ok?”
“If you wanna fuck me then you should keep being nice,” Kaminari chided, hoping he sounded more confident than he felt.
He pushed Bakugo backward, dragging his mouth over his chest to hide his face (also because God did he want to put his mouth over every expanse of this abdomen he could).
“Do you want me to fuck you?” Bakugo asked.
Kaminari wondered if it was hard for him to keep his voice so level. He wrapped his hand around Bakugo’s cock, brushed his thumb along the underside. Bakugo hissed.
Kaminari dipped his tongue into the little indent of Bakugo’s navel.
“Yeah,” he said honestly, “I really, really do.”
Bakugo moved like he was about to sit up and Kaminari’s hand shot out reflexively, crackling slightly with excited electricity that he just barely managed to will away before pushing Bakugo back down. Bakugo’s cock jumped in Kaminari’s hand. He leaned down and swiped his tongue over the bit of precome at the tip.
Bakugo cursed but stayed put.
“If you want me to fuck you then cut that shit out.” His voice sounded tight, hand hovering like he wanted to touch Kaminari and wasn’t allowing himself.
“Don’t come,” Kaminari said matter of factly, grinning up at Bakugo.
“You’re fuckin’ pushing it.”
“I know, I know,” Kaminari conceded. Bakugo was honestly being surprisingly accommodating, so he added apologetically, “I just wanna touch you a little.”
And he did. He wasn’t trying to torture him or anything. But Bakugo had already seen Kaminari splayed out in a messy heap and it was actually kindof calming to take a moment away from the attention. Plus, it’s not like he got to inspect all the little ridges of Bakugo’s very nice A+ top of the class abs every day.
“Have you done this before?” Bakugo’s rattley voice made Kaminari pause where he was mouthing the side of his cock.
“Done what?” he asked, going back to drag his tongue against the head.
Kaminari looked up at Bakugo’s rolling eyes.
“Fucked.”
“I’ve-” he started, but then decided not to skirt around it. “No.” A pause. “But it’s fine! I’m not gonna be weird about it I promise and it’s not like I haven’t-”
“Oh my God shut the fuck up,” Bakugo interrupted, sitting up and holding Kaminari’s shoulder reassuringly (or it would have been reassuring, just like his soothing touches would have been soothing, if those words didn’t seem so out of place). “It’s fucking fine. If you want to it’s fine.”
Kaminari looked at Bakugo’s face, trying to search for any weirdness and finding none. He smiled, relieved. And then flopped back shamelessly on the bed where he’d been before.
Bakugo tried to seem annoyed but didn’t quite get there.
“Touched me enough then?”
“Uh-huh,” Kaminari nodded.
Bakugo climbed over him, the warmth of his body making Kaminari shiver expectantly, and flipped open the bottle of lube again.
“If it hurts,” Bakugo said again, squeezing some onto his fingers, “tell me. Got that?” It sounded, fittingly, like a threat.
“Got that,” Kaminari confirmed, smiling.
Without ceremony, Bakugo slipped two fingers into Kaminari, already loosened up from the plug, pumped just twice before adding a third, which he took without much difficulty.
“Without much difficulty” melted quickly into “enthusiastically” as Bakugo continued, fucking his fingers in slowly and curling them every so often to catch on that spot that made Kaminari’s whole body jolt.
“Ok, Sparky?”
Kaminari didn’t trust his voice. He nodded, out of breath, and watched with rapt attention as Bakugo spread lube over himself.
He was sorely tempted to just tell Bakugo to please fuck him into the mattress however he saw fit, but instead, as Bakugo lined himself up, nervousness interrupted again.
“Just-” Kaminari hated himself the second it left his mouth, but continued anyway, “um- not too hard, ok?”
“Yeah.”
And then Bakugo was pressing in. So slowly. And he was bigger than his fingers and hotter than the plug and it didn’t hurt and it felt really kindof strange and he had heard this before but now he maybe understood what feeling “full” meant.
Bakugo was watching his face for any discomfort. There wasn’t any.
But when he bottomed out, Kaminari squeezed his bicep, eyes closing and little eyebrows pinching together slightly, and Bakugo paused.
“You ok?” his voice was the slightest bit strained.
“Yeah. Yeah, just give me a minute.” Kaminari said, shifting a little, trying to get used to the feeling. It didn’t hurt. It was just a little.. Overwhelming. “Mmf” he hummed, rocking his hips a little to test whether he wanted Bakugo to move yet. He felt impatient with himself, trying not to be awkward. He felt like a lot of time was passing even though he knew it was likely not that long. “Sorry.”
His eyes had stayed closed, so when Bakugo kissed him, it came as a surprise. He licked into his mouth slowly, patiently, and Kaminari relaxed a little.
“Breathe,” Bakugo said, hand carding through his hair and pushing it away from his face. Kaminari did, and he was a little more relaxed by the time Bakugo was licking over his pulse. Kaminari rocked his hips again and was caught off guard by how much better it felt.
He tilted his head back. “Oh.”
“Mm,” Bakugo hummed against his throat, “fuck, you feel good.”
Kaminari realized Bakugo had been still since he’d asked him to wait.
“You can move now.”
His breath caught in his throat immediately. Even with the slow pace Bakugo set, every wet slide in and out had him choking out some new slutty sound he didn’t know he could make.
“Shit, you’re gonna fucking ruin me,” Bakugo said against his mouth.
Then he pulled almost all the way out before pushing back in just as slowly. Fucking him like that-- Kaminari knew this was supposed to just be the beginning but he already felt embarrassingly close to coming. When Bakugo reached down and touched him, he almost couldn’t push his hand away fast enough.
“Don’t. If you do that I- I’m not gonna-”
Talking was hard.
“You gonna come just from this?” Bakugo punctuated with a thrust that was a little harder, a little faster.
Kaminari nodded helplessly. A little static crackled where he held Bakugo’s wrist.
“Sorry,” he said, letting go of it immediately.
Bakugo pushed his thigh up, angling him in a way that made his cock reach that much deeper. Kaminari pressed the back of his hand over his mouth, halfheartedly trying to muffle some of the sounds he made. It fizzled with sparks. He couldn’t care enough to stop it.
“Do that again,” Bakugo said.
“What?” Kaminari’s brain felt out of focus on everything but the grind of Bakugo’s hips.
“Shock me,” Bakugo breathed out.
Normally Kaminari would argue there needed to be some kind of conversation around this, but at the moment, all he felt was blind, stupid arousal at the thought. He brought his hands to Bakugo’s hips, mouth sliding into a mischievous smile.
Bakugo must have felt the electricity in the air, in his hair, before anything even happened, because he added (with impressive coherency, born from maybe a little necessary self-preservation): “Don’t fuck up.”
Without waiting for any other kind of cue, Kaminari sent a wave of electric pulses through his hands and into Bakugo’s skin.
Kaminari might as well have shocked himself because the violent stutter of Bakugo’s hips suddenly fucking into him hard at that perfect angle knocked the wind out of him. And the sound Bakugo made as his head slumped forward next to Kaminari’s would probably haunt his dreams. So without waiting for him to recover, Kaminari did it again.
“Fuck I’m- I’m-” Kaminari stuttered, and then whimpered, totally powerless to stop the noise from tumbling out.
“Holy shit,” Bakugo gasped, voice raw. He was shaking, clearly trying to measure his thrusts for Kaminari’s sake. “You ok?” he gritted out.
How was Kaminari supposed to answer that.
“Yes, yes.” His hands wandered, feeling suddenly desperate to touch Bakugo everywhere. “Fuck it’s so- I’m- Please don’t stop.” His hands found their way back to Bakugo’s hips. “I wanna feel you come.”
“Do it again.”
Kaminari almost sobbed from the gravelliness of his voice alone. He grit his teeth and nodded heavily.
And this time Kaminari place his thumbs right at the tops of Bakugo’s inner thighs, right on either side of his cock where it pushed into him, and sent out deeper, longer pulses of electricity.
Bakugo crumpled forward with a choked noise, jerked his hips again and Kaminari wanted him to do it again. Needed him to fuck into him that hard, god, just once more, so he sent another pulse. And when Bakugo shoved his hips forward with it, Kaminari’s orgasm hit with a cry that would have been dangerously loud had he not clapped his hand over his mouth in time.
It took him a second to realize that Bakugo was coming too, shaking with it, a filthy noise drawn out of him that sounded almost painful. And it made Kaminari squeeze his thighs together, hips undulating, free hand flying up to pull tight on Bakugo’s hair. Bakugo was milking them through it and the hot, over-wet slide from his come was disgusting in a way that made Kaminari feel like he was going to lose his fucking mind.
By the time they stilled, Kaminari was twitching with oversensitivity.
Bakugo pulled out gently, shoved Kaminari a bit to make space, and fucking collapsed.
“Fuck,” he breathed.
Kaminari was too out of breath to say anything. He reached underneath them and yanked the towel from under his hips.
“Gimme that,” Bakugo said, grabbing the towel. He took it easily, Kaminari’s body so tired and heavy it felt like too much effort to be bothering with it anyway.
Bakugo didn’t seem too much better off. Kaminari was honestly impressed when he hauled himself off the bed without too much groaning to walk over to the bathroom. The water ran briefly and then he was tossing the damp towel back to Kaminari, heavily sinking back into the mattress beside him.
Kaminari cleaned himself off quickly and tossed the towel onto the floor. They laid there for a second and it struck Kaminari as pleasantly, surprisingly un-strange.
“Fuck,” Bakugo said again, shoving Kaminari’s boneless body hard enough that he groaned in protest, “you fucking VIRGIN. I don’t think I’ve ever come that hard in my life.”
Kaminari smirked. “I didn’t say I hadn’t done anything. You should be glad I got the zap practice out of the way with someone else, really.”
Bakugo laughed a bit. His eyes were closed.
“Must’ve been a lot of practice.”
There were a lot of things Kaminari could have said to that, but it seemed like too much work to defend himself.
“Worth it,” he said instead.
Then, because once the thought occurred to him he was completely powerless to stop, he said mischievously, “You can call me Denki again anytime, you know.”
Bakugo didn’t open his eyes.
“You call me Katsuki in public and I’ll fucking kill you.”
Kaminari summoned a bit of energy to roll onto him, tilting Bakugo’s chin to kiss him lazily.
“Katsuki,” he repeated, murmuring against Bakugo’s mouth. He thought he felt Bakugo smile against his lips, just a little.
