Work Text:
Kirishima isn’t exactly sure how he got to where he is right now. His head feels thick and heavy. It had been a while since he had fallen into such a strong level of subspace. The last thing he remembered was going to classes, training, and agreeing to train further after class with Bakugou. The blonde had secured the gym space for them for a few hours later in the afternoon.
They had spent those hours pushing themselves, running several obstacle courses and then simply testing their quirks on one another. Kirishima going unbreakable, seeing just how long he could hold it.
Bakugou launching strike after strike against industrial pieces. Finally though it had ended with them sparring directly with each other.
Hit after hit, skin hardened and broken. Bakugou’s palms swelling in the aftermath. Kirishima remembered them forgoing the gym showers. The dominant suggesting, considering the hour, that they use the ones within the dorm so that they could then easily slip into the bath right after instead of out into the cold night air. Besides, someone else was coming to use the gym since the time Bakugou had signed out for had already expired. It was best for them to get out of the lockers and just head back to the dorm building.
It had made sense at the time. Besides, Bakugou was typically right about, well, most things. As long as the topic wasn’t about Midoriya or being the number one hero, the blonde tended to think rather logically and suggest the most efficient and best course of action.
However, as they made their way back to the dorm, Kirishima attempted to be thoughtful and stay close to Bakugou. The blonde hated the cold and leaving the gym in midwinter while still mussed from their workout meant that the chill would likely impact the blonde even more than normal. Thus, Kirishima stayed close to him, knocking their shoulders together a few times and allowing his own body heat to help keep Bakugou warm.
Usually, Bakugou would protest such overt closeness, yet tonight he had not. It had been curious, but Kirishima didn’t want to question it. He liked helping his bro out, keeping him warm, and if it meant he could take several lungfuls of the caramel undertones of Bakugou’s scent heightened by his sweaty state...Kirishima would certainly never think to complain.
They had made it back to the dorm, Kirishima was certain of that - he remembered making it into the warmth, yet Bakugou hadn’t shoved him away. Kirishima had glanced around the common space, noting it had been mostly empty except the couch. It held one occupant on it and another exactly in front of it. Midoriya and Todoroki to be exact.
Ever since earlier in the week, when it had come out that the pair had decided to attempt a trial contract with one another, they had been basically inseparable. They were constantly with each other unless something with the day’s lesson forced them apart. Hence why it wasn’t too shocking in the quiet of the late evening to see Midoriya lounging on the couch and Todoroki kneeling in front of him, head pillowed on the green haired male’s lap, scarred fingers carding through two toned locks.
Honestly, Kirishima found it endearing, sweet - the pair seemed so well-suited. Kirishima knew though that anything Midoriya-related usually led to Bakugou having a massive fit- and if the tirade earlier in the week when the couple had been discovered had been anything to go by, Kirishima expected the current sight would get Bakugou to explode...yet once more he simply...didn’t.
If anything, instead of moving away from Kirishima to curse at the couple before him, Bakugou just barely glared at the pair and then well, Kirishima must have imagined it, but the blonde seemed to press his shoulder even closer to Kirishima’s own. They had headed to the elevator from there and Kirishima could have sworn Midoriya had winked at him, though he had no idea why the other would do such a thing - but it had just been a split second before he had gone back to petting Todoroki and then...Oh.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Kirishima blinks red, pupil-blown eyes and owlishly looks up as a not so gentle tugging sensation on his hair refocuses him - Kirishima then realizes he himself is on his knees and his face is pressed into something which smells so good - that same caramel scent. As he turns his head, red eyes meet another equally red pair.
“Oi, shitty hair - you’re supposed to be getting my clothes off, not bore holes into them. Are you already that far gone from just being put to your knees?” Bakugou’s voice as it rings through Kirishima’s ears is all consuming. It sends small shivers through him. Yes. This - he had.
Kirishima had gone in the elevator with Bakugou and the jostling of their shoulders had become Bakugou actually throwing his arm around Kirishima. Pulling Kirishima in for just a moment and that thick, heavy scent of caramel and spice was overwhelming in that split second. When the elevator stopped off at their floor - Bakugou had started to pull his arm away, cheeks reddened as if embarrassed by his own sudden gesture of dominance - but Kirishima had found himself not wanting it to stop. Instead he had...he had followed Bakugou right into his room, leaning into the arm to prevent its removal. Skipping past his own room entirely and just following Bakugou into his own.
There was another indignant huff from the blonde above, and a second tug. Right, he was supposed to be taking Bakugou’s clothing off for him. Kirishima lifted his head off of Bakugou’s knee despite how heavy it felt. As if it might topple forward on its own without without a place to rest it. The problem was that the order was just...it was so vague, and with his mind feeling as if it was swimming through fog, Kirishima couldn’t figure out where to even start on such a task. It felt so monumental right now despite how truly mundane it was in truth.
Without a more succinct order to keep him focused, Kirishima once more felt himself begin to wander, his eyes drifting towards the source of that strong scent which had enticed him earlier lay.He couldn’t help finding himself staring, unable to focus on the vague task before him. He wanted to press his face so badly into the mass settled there.
It was just...so manly. The large bulge in the dark pants radiated a warmth and utter level of masculinity. A dominance, an all encompassing aura which like heat to a flame pulled Kirishima in, he was just about to lean forward and attempt to claim it again when a boot was suddenly thrust into his face. The side of it placing a swift yet light kick right to his cheek, startling the redhead from his inner revelry over Bakugou’s concealed cock.
“Pay the fuck attention shitty hair, you don’t just get to go to the main prize without working for it. Or what the hell do you need, a direct and proper ordering on how to do this?” Bakugou indignantly chastised, though it seemed - there was a level of smugness there. The pride the blonde felt over the fact that his crotch was so overwhelming it sent Kirishima to a singular level of focus over it.
Kirishima didn’t even get a chance to respond before Bakugou was doling out his first order. “Focus on the damn boot first.” The words struck a chord in his head - yes, a direct command. A task he didn’t have to think on where to start. How to begin it. All he had to do was listen and obey.
Kirishima brought his hands up to pull Bakugou’s left leg, which had been resting on his cheek, a little lower, resting the sole of the boot right up against his chest. One hands holding it there at the base while the other took a moment to splay over the firm leather material. Feeling it, taking in just how supple the material felt on his overly sensitive hand - the nerves of it working overtime after a overuse of his quirk during their training.
He just had to take it off, that wouldn’t be difficult at all. It was something Kirishima could easily do, yet he found himself lingering just a second more on that supple feeling. It was so nice and without even further thought the redhead leaned down and pressed his lips to the front of it, right against the dark leather. It felt nice, it felt right in such a way that Kirishima hadn’t anticipated.
The shoe belonged to Bakugou - he couldn’t just unceremoniously pull it off and throw it to the side. That seemed so wrong to Kirishima. This dominant before him held such strength and power - not only did he deserve reverence, but so did anything on him. Thus with no hesitation the gentle press of Kirishima’s lips dragged along the side of the boot, placing somewhat sloppy kisses onto the leather. There was a pink tongue swirling small, undefined patterns across the surface of the boot.
It tasted like deep smoke, and that same caramel undertone which had just become unianimus with Bakugou in Kirishima’s head, and of course also leather. Rich, dark real leather. Nothing fake, such a thing wouldn’t suit Bakugou and the strong image he presented and actually held at all.
Anything and everything Bakugou did was authentic. The blonde was basically every conception of a dominant, manly alpha male come true to form and it made Kirishima’s stomach churn with a seemingly unquenchable heat. He wanted him so badly, more than anything and in this moment Kirishima had him and would not waste it. He would worship every inch.
Teeth edged along the leather, gentle, delicate and reverential as they also took took in the boot, heading up and up - the placement of puckered lips in affectionate gestures done every so often until Kirishima made his way to the true mark of his mouth’s journey; the laces.
Moving his teeth ever so gently Kirishima used to pull and tug at the knots which bound the boot to Bakugou’s foot. Loosening the straps until they pulled away enough that Kirishima could lean himself back and the boot which his hands clasped came away from Bakugou with him to be tenderly placed to the side.
Without a moment of time wasted Kirishima settled his grasp onto Bakugou’s right leg and pressed it up to himself with no hesitation, a small bit of dirt coming away onto Kirishima’s shirt, but he paid it no mind. It didn’t matter right now, it wasn’t important. Anything that made a mess of him unless purposefully done by Bakugou held none of Kirishima’s attention.
Instead Kirishima raptly focused said attention on the second boot. He wanted it closer to him, wanted Bakugou closer to him. He pressed it up further then his chest to his face and ran his cheek across the surface of the leather garment. Feeling as Bakugou tipped the front of it up and it landed just against his forehead, nudging there, stepping there, putting Kirishima literally under Bakugou’s boot. The redhead’s cock twitched within his pants at the feeling of that mild pressure. Of knowing that he was both literally and emotionally under Bakugou’s heel.
“Tch, you know, like this, your hair actually doesn’t look half bad.” Bakugou crooned to down below and though Kirishima couldn’t see it he could hear the smirk formed on Bakugou’s lips and it made the redhead’s heart thump even faster within his chest. Bakugou was smiling! He was pleased with Kirishima!
At such praise from the dominant Kirishima took some haste with his action, his tongue laving across whatever part of the boot he could get his mouth on which fluctuated as Bakugou seemed now to not be content staying still and brought the appendage several different directions to make Kirishima give chase, work for his worship of it. Kirishima was more than up for the task of it, anything worth doing was more than worth a little extra work! Plus Ultra!
With tenacious movements of his own to combat Bakugou’s ministrations Kirishima had actually managed to place several kisses to the boot and drag his tongue over even more spots whilst using his teeth to unlace it. Though before he could reach up his hands to grab it, he found the boot moving down his face, across his nose against with just a miniscule amount of pressure as it went, just a hair past feather light in its touch as it skirted down Kirishima’s body.
It went over his neck, stopping at his right peck with a swift kick to the breast, right onto his concealed nipple drawing a moan from the sharp toothed youth. It drew lower and lower before settling on what was Bakugou’s destination for the boot just barely still on his foot; Kirishima’s crotch.
Within an instant the boot went from barely hanging onto Bakugou’s foot to being fully on it as the blonde pressed his boot right into Kirishima’s cock. Stepping on the bulge which with its hardness made tight the confines of the redhead’s usually baggy dark pants. The garment an inferior one to that which pressed upon it in all its leather glory, slicked and shiny from Kirishima’s mouth that he has used to had cleanse and worship it.
There was a chuckle and for the first time Kirishima brought his eyes up to focus back on Bakugou. He was surprised to see in the time he had been working on Bakugou’s boots that the blonde had removed off the top part of his costume baring his chest completely, hands no longer having any gloves, looking tender. It had seemed though all his other upper body vestments had been done away with that the mask around his eyes had not though they did little to prevent Kirishima from noticing the small crinkle of pleasure which shone on Bakugou’s features.
“I don’t think these boots have ever looked this good before, you’ve got a real talent for this, shitty haired Eijirou.” Bakugou said, the amusement as he complimented Kirishima for such a thing lost on him. Bakugou had called him by his first name, it wasn’t uncommon for dominant to relate back the dynamic of power shift by using their submissive’s first names whilst still going by their own surnames.
Yet, for Kirishima it once more settled a part of him. Usually dynamics meant very little to Kirishima. It didn’t matter to him that he was a submissive, the redhead had promised himself after gaining entrance to UA that he was going to be different and not allow any assumptions, be they from society or himself, stop him from being the most chivalrous and manly hero!
It led to Kirishima not typically giving into his deeper urges, finding fault in how they could hold him back from being hero. Sure he accepted pats here and there from Kaminari or Sero when he did something well and at times he even let Mina comb her fingers through his hair, settling him...but he couldn’t remember the last time he had let someone put him onto his knees or bring him into subspace since he had moved into the dormitories and he had avoided it when he could at home when it came up.
Thus having Bakugou use him like this, give him a compliment befitting a submissive whilst Bakugou was also keeping him in this position ye still also giving their usual level of banter between them. It settled that aching need within Kirishima.
He could be a submissive and still be hold the respect of being one of Bakugou’s comrades. Perhaps one of his only comrades that he seemed to deem worthy of any respect. Kirishima’s heart likely couldn’t thump any harder in his chest without risking breaking open his ribs.
Kirishima gasped at the sudden pressure in his crotch as once more Bakugou stepped down. “What, this feel so good you’re losing it again Eijirou? Not enough to do?” Bakugou questioned.It didn’t help that at the same time Kirishima’s cock twitched against Bakugou’s boot, giving away just how good he had felt during all of this.
At such a comment, Kirishima raised his head up to see that at this point Bakugou had one hand on his chest teasing along his nipples whilst the other was moving lower ending its descent at his own crotch. Bakugou looked like carnal sin incarnate.
“If you’re just going to just stare off into space with your mouth hanging open I might as well be filling it - keep those teeth to yourself though.” The blonde huffed as his fingers drew down his fly and then reached in, Bakugou had clearly gone commando, and fished his dick out of his pants, lifting the hardened member out of its confines so it could branch out its full glory.
The small glances Kirishima had gotten of Bakugou’s cock in the showers didn’t do it justice at all. Exposed out in the open it looked absolutely perfect. It held heft to it without being too thick for its length that it looked out of proportion. In fact, it was near perfectly proportional and nestled in the most well groomed golden haired triangle, not a stray pube insight as if the cock had a golden crown above it.
“Go on, take it into your mouth and suckle, just a little - start off slow and mostly just warm me.” Bakugou ordered. “Be careful with those chompers though shitty haired Eijirou.” The direct nature of said declaration and how detailed it was made Kirishima’s submissive hindbrain trill, oh yes, he could do exactly those things. He could be a good cocksleeve for Bakugou.
There was zero hesitation in his actions as Kirishima pressed himself into the space between Bakugou’s legs once more, this time opening his mouth and making sure to carefully pull his teeth back just as Bakugou had ordered. He was taking in every bit of Bakugou pressing himself into the blonde as much as he could, drawing them closer and closer. There was no way a Kirishima would allow even a single inch of Bakugou’s cock to exist outside of him and kept up said ministrations until his nose bumped into Bakugou’s pubic bone.
Kirishima held his head forward for just a moment, his nose luxuriating in the golden curls, drawing in that thick, rich scent that was all Bakugou which resides within them. That same caramel which cloyed others was nirvana for Kirishima. He wanted to bathe himself in that scent, cover himself in it until any trace of the supposed earthen tones which belonged to himself were just barely there.
At that moment Kirishima gently let his tongue lav at the underside of Bakugou’s dick with soft movements following his orders to a T, mouth holding it all in and some even slipping into his throat. It felt slightly snug, but in the best of ways, like Bakugou’s cock had been tailor made to slot right into that space.
Kirishima had never been more thankful to his middle school self who had used his first submissive knotter dildo he’d gotten at puberty to ensure that his gag reflex would be a thing of the past. It allowed him now to do the manly thing and take Bakugou’s length entirely in,
Kirishima would worship it all as he let his tongue trace along the thick throbbing vein that ran along the entirety of the length, he could feel the moisture collecting at the corners of his mouth and didn’t mind them. They were proof that he was taking proper care of the dominant before him, letting himself be used as a perfect cocksleeve.
Twirling his tongue forward to get to the tip, gently using it to probe at the slit there, small, little movements. Kirishima was listening like a good boy for Bakugou and felt a calloused hand slip into his hair that was slightly softened and messed up from his workout. The collected sweat dampening even the excessive amount of gel he had used to style it, the fingers entangling in his hair felt so right. Like it belonged there just as much as Bakugou’s cock did in his throat.
The hand seem to make a home there, resting against his scalp, digging fingernails in occasionally whenever Kirishima seemed to move too quickly, it was there to steady him and to make sure and keep the redhead still until Bakugou wanted him to do otherwise.
Kirishima couldn’t tell just how much time had past with him pressed close to Bakugou, just huffing the blonde’s scent as every so often the redhead dragged his tongue over the other’s dick, tracing patterns out or just moving from one end to another of the few veins which crossed along the shaft. Now and then hollowing out his cheeks to give a few sucks along it, but not for awhile.
Kirishima head had grown fuzzy again, eyes slipping shut, unable to process more than the weight resting against his tongue, the heavy weight which cemented him to this spot. It almost felt like without it then he might just float away. It was why when the hand on his head started to pull him back he let out a whine, trying to seal his lips further around the appendage in there. He couldn’t let it go!
“Hey, none of that shitty hair, let go, trust me you’ll be getting it back in just a few seconds.” Bakugou’s voice broke through the haze and Kirishima stopped struggling and let himself be pulled away despite how wrong it initially felt. If his dominant told him to do it then it must be the right thing to be doing.
As he was removed from the blonde’s dick Kirishima could see that his drooling had led a trail down his chin and onto Bakugou which in slow rivulets had made their way to his nuts giving them a minor glisten. It took all of Kirishima’s inner control to be a good boy and not simply push himself back down and roll them into his mouth. He wanted them so badly, but he hadn’t been given permission to have them yet.
“There we go, that’s a good boy. Now open up nice and wide for me, fuck, you look so perfect like this, eyes nice and hazy, you don’t give a fuck about anything but my dick do you right now Eijirou? Just a happy little glazed over sub - a perfect fleshjack to be used.” Bakugou groaned, as turned on as Kirishima by what he was saying, the cock now out and in front of Kirishima’s face bobbing in its reaction to the words.
A second hand came down onto Kirishima’s face, one on either side as Bakugou’s smirk drew wide around his face. Nearly taking it over. “Time for some real fun, remember, keep it open.” And that was all the warning Kirishima got as with a fervent tug his head was brought forward right when Bakugou jerked his own hips up and the blonde’s cock was shoved right into him. Pushed all the way in to only then be simply and swiftly pulled back.
The hands on his head now digging their nails into the flesh and hair there as he was once more harshly tugged back onto Bakugou’s cock. Over and over, wrenched forwards and backwards, truly being used like a tool to pleasure Bakugou with no thought to his own, pulling in lungfuls of air when the opportunity arose. If it wasn’t for the copious amounts of drool dribbling out of his mouth by the rampant thrusts then friction of the movement he would surely be chafing Kirishima’s lips.
It was the continual bend and snap of Bakugou’s hips as he fucked Kirishima’s face. All of this had Kirishima’s heart veritably singing in joy. He was being of such good use for the dominant. A good, wet and warm sleeve. It didn’t matter that he could hardly breathe or that the tightened confines of his own pants from his erection were starting to get painful, none of those things made past a pereforary thought or feeling compared to just how fantastic being used felt.
It wasn’t just his head which felt like it was floating either, there were points of blackness starting to seep in around the edges of Kirishima’s vision. The vigorous pace which Bakugou was fucking his face left little opportunity for proper breathing, or much breathing at all.
It seemed then though that Bakugou’s jackhammering was starting to lose its unyielding paces, jutting into awkward movements and stuttering of his hips, at one point crashing into the side of Kirishima’s cheek as if in a lewd kiss - the blonde seemingly to lose a smidgen of his composure and control the boot which had just been lightly grazing at Kirishima’s crotch dropping right down and stepping with enough pressure that is sent a small jolt of pain into the redhead causing his to cum right then and there smattering the interior of his black pants white.
Kirishima didn’t so much see Bakugou cum as much as he felt it, the thick pulse of his cock and then the full assault of his senses as jizz filled his mouth, poured right into his throat and blocked everything else from existence. There was no way he could breathe through the copious amounts of cum blocking his airway. Kirishima’s eyes slipped closed and as his lungs gave way to the lack of oxygen until there was nothing, just...darkness. A warm, welcoming embrace of it which Kirishima allowed himself to fall headlong into it.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
“....come on now rocks for brain, gotta drink some of this shit or else you’re not going to be able to talk tomorrow...though, that might not be the worst thing. You talk too much anyway.” Kirishima came to for what felt like the hundredth time that night to Bakugou’s voice, though this time there was a surprising level of warmth to it. Something different then the authoritative and goading tone he had taken earlier. It was still just as dominant, it was just softer.
There was the cool press of glass to his lower lip, and though it hurt Kirishima willed his lips to part so that Bakugou could bring the cup forward allowing the redhead to take several small sips which helped soothe the ache in his throat. That part of his body felt as if he had swallowed a handful of caltrops or well, been throat fucked to the point of blacking out.
As he grew more aware of his surroundings Kirishima realized he was laying in Bakugou’s bed and in addition to that he was also completely naked. What was perhaps even weirder though was that he even felt slightly refreshed which made no sense considering one of the last things he remembers was cumming right into his pants on one end and then the overwhelming pulse of cum into his mouth.
Trying to process such a conundrum whilst continuing with his drinking Kirishima looked around the room, surprised once more not to be seeing his discarded clothes on ground and when his gaze went a bit higher from the floor to the nightstand he noticed several small towels. Had Bakugou cleaned him off afterwards? He had to have done it considering the lack of tackiness in Kirishima’s crotch. The blonde was also still guiding the glass to Kirishima’s lips as he drank and when he had finished the whole thing had pulled it away.
It was an unexpected level and type of shown care. Kirishima had never doubted Bakugou cared about him, the blonde was his best friend after all and he would show it in his own way, yelling about Kirishima’s lunch choices of just meat and carbs, shoving all kinds of vegetables that he believed Kirishima should be eating. Glaring the redhead down until he did just that. There were even times when Bakugou would cook himself nutritious bentos and make not just one for himself, but one for Kirishima as well, dragging Kirishima off alone to eat them together, going on long winded rants about tall the reasons Kirishima needed certain vitamins or higher levels of calcium because of his hardening. Then of course all the hours he had spent helping Kirishima study for test after test, again there was more yelling, but it was just how Bakugou showed he cared typically.
These actions though, this gentle care wasn’t something Kirishima had been all that sure Bakugou was even capable of giving yet here he was having used towels to clean Kirishima off from head to toe, or well, at least crotch. Helping Kirishima drink water to ensure he didn’t get dehydrated from their prior ministrations.
“I can see the gears moving in your head again, you with me shitty hair?” Bakugou questioned, the hand which had swiftly removed the glass was now against flipped around, the back of it pressed to Kirishima’s forehead.
“Ye-” Kirishima attempted to respond, but his throat felt aflame with the action.
“Don’t fucking talk, just sound it out or some shit, you’re going to be too sore if you try to talk right now, idiot. No talking.” Bakugou said, it came across like an order though, once more that authoritative tone pushed into those last few words Bakugou spoke. It was direct and there and it made those same fuzzy edges just barely draw along Kirishima’s mind.
“Hey, I said no more fucking spacing out, what’re you fucking Roundface now?” Bakugou barked, though there was no real bite with the sentiment as his hand reached out to the side, to the nightstand and picked something up and brought it up. They were papers.
“When you’re more fucking there we’re going to sign these things, stupid shitty fucking Deku may have gotten his papers to Icyhot first, but we’re going to do it better and then…” Bakugou trailed off, the hand not holding the aforementioned papers moving up to draw along Kirishima’s neck, there was some slight bruising there from where Bakugou had pressed his boot into the space at some point in their play. “...then I’m going to collar you shitty haired Eijirou.”
Those words were uttered with such a level of sincerity, it wasn’t an if for Bakugou, but simply a when. He would lay his collar on Kirishima so that everyone would know who he belonged to. Kirishima relished such a thought, his cheeks heating up. There was no one he could ever imagine belonging to other than Bakugou.
“Now move over. I want to go the fuck to sleep. You’re staying here tonight.” Bakugou said, putting the papers down and pulling the blankets of his bed aside, slipping himself into the bed and crowding into Kirishima’s space, pulling the redhead against his chest as he held him there, arms possessively intertwining around Kirishima’s sides, caging him in, yet Kirishima honestly couldn’t imagine anywhere else he would want to be besides within Bakugou’s hold.
Soon they would have papers, then a collar and full contract and well, Kirishima couldn’t picture a better future then one spent with Bakugou, held within his firm grasp, Kirishima knew they would become the most amazing heroes! Though, secretly deep down, Kirishima relished in the thought of the next opportunity he would get to be under Bakugou’s boot. The thought overcame him as he drifted off to sleep.
