Kirishima Eijiro x Bakugo Katsuki

Bakugo was quick to leave from his agency building. Stepping out into the fading sunlight, he could feel his nerves kicking in. Adrenaline was pumping through his veins, and a hot excitement was burning him up from head to toe.

Tonight is the night.

The blonde couldn't keep from checking his phone as he made his way  through the parking lot towards his black and orange Ford Mustang. 

No new messages from Eijiro... I'll just have to meet him there.

Bakugo's lips twitched into a small grin, and as he strapped himself into the drivers seat of his car, he couldn't help but wonder what other straps he'd find himself in that night.

On special days like today, Bakugo and Kirishima would take off of work early and head out to their secluded cabin in the mountains. Their combined agency ranked as the number one hero duo agency in the world, and their popularity as Pro Heroes made it hard for them to do much of anything at their house. There was always press attention on them, and the media was so damn nosy. On top of this, work had been so busy lately that their special days had been happening less and less often.

Bakugo had been surprised to see the small black envelope next to him in bed that morning instead of the usual sight of his sleepy, messy haired fiancé. However, when he opened the letter, every particle of his being was lit up in burning hot arousal. It was finally, finally their day. It had been so long since their last trip up to the cabin, that Bakugo had completely forgotten who's turn to be dominant it was. The letter assured him that it was definitely not going to be him.

Pulling the car out into the roadway, Bakugo's stomach was doing flips. He clicked on his radio, but couldn't stop himself from imagining all of the things Kirishima could possibly have in store for him. Eijiro had left their work earlier than him, leaving Bakugo yet another small black note at his workstation. He had done this to remind him of their change of locations, as on most Fridays it was their combination movie night and workout, "Movies and Muscles."

Bakugo, however, wouldn't have been able to forget it if he wanted to. He had been thinking about it all day. Every time he thought he might be able to focus, flashes of red hair and shining white teeth breeched his mind, stirring something deep inside him and driving him crazy.

Bakugo had been watching for his fiancé all day, but had barely seen hide of hair of him. This was incredibly unusual, as the two were generally inseparable. If they ever had to work away from one another, Kirishima would always find the time to call or visit him. Not today though, in fact, it was as if he had been specifically avoiding the blonde. He had even left the note on his desk while Bakugo was out getting lunch.

Bakugo let out a soft 'tch' as he thought of this. That damn bastard was trying to rile him up. Glancing up at the darkening sky, Bakugo's eyes narrowed in delight.

I'm making great time, the cabin is off the next exit.

~~~

The small brown cabin's porch lights were on when Bakugo finally pulled into their jagged stone driveway. Taking a deep breath, the blonde popped open the door of his sports car and stepped out into the wash of vanilla light.

Fucking Christ, I just want to run in there already.

Bakugo tutted softly to himself as he steadily made his way up their twisting pathway. He pulled out his house key and fumbled with it for a minute before stepping into the dim light of their entryway. He had just closed the door behind him when he noticed the black letter laying on the floor, atop of a decently sized brown package.

A shiver excitement ran down his spine as he bent over to look at the glossy envelope. "These damn letters." He grumbled halfheartedly, opening it up and hungrily reading through the words.

My dear Katsuki,
I'm glad you have finally arrived. By this point, all of my arrangements have been made. You may slip into what I got for you and come downstairs immediately.
~Eijiro

A smirk spread slowly across his face as he impatiently tore open the paper box. "Fucking Hell." He murmured, dumping the contents out onto the floor.

There's so many damn straps.

Lifting them up, he quickly had a general idea of where on his chest they would go. Also on the floor was a tight, black, leather speedo, a pair of leather wrist cuffs with heavy silver rings attached to each one, a deep red collar with yet another metal ring, and a thick black blindfold. Not wanting to wait any longer, Bakugo stepped into their small office and changed. He was feeling a bit tight in his straps and briefs, but made his way anyways to the basement door.

Bakugo typed in the code for the door and swung it open. He paused a moment, standing at the top of the stairwell and looking down into the warmly lit room below. Katsuki held the blindfold loosely in his large, rough hands and sighed, weighing his options. He could either risk falling down the stairs to their dungeon or be immediately punished by Kirishima for not following his instructions.

Fuck... I don't want to be punished right away... guess I'll just be careful.

Bakugo awkwardly tugged the blindfold over his eyes and reached for the railing. His sight now gone, Katsuki listened closely for the reassurance of the locking click from the door behind him. Slowly, he began making his cautious decent down their staircase. He only let go of the railing when he could finally feel the cool stone on his bare feet.

"Eijirooo, where are youuu?"

His tone was playful as he walked carefully through the open space. The world around him was pitch black and he couldn't hear a damn thing. Sharp threads of excitement were zapping through his body and he ached for the reassuring growl of his fiancée's voice.

He gasped as sudden thick arms wrapped around him from behind, feeling Kirishima's warm, wet mouth press into his exposed neck. "There you are." Bakugo said in a lower voice. He moved in an attempt to turn in his lover's arms but was instead held firmly in place.

Kirishima's lips traveled slowly up his sensitive neck to the lobe of his ear, rolling it gently between his sharp teeth before whispering softly.
"Together we are..."
His breath was hot and it tickled his skin, Katsuki shivered before replying huskily, "An unstoppable force."

This was the code that was only spoken in their dungeon. The two used it ensure their identities, as they had had enough contact with shapeshifting villains in the past to want security in their actions.

Bakugo could feel Eijiro's lips shift into a smile against his neck. "Katsuki..." he murmured softly, his voice warm with affection and an unmistakable longing. "Do you remember the safeword?" Eijiro's gravely voice forced yet another involuntary shudder up the blonde's spine. Bakugo nodded, hot arousal sending tingles of excitement throughout his body.

Kirishima's hands travelled slowly over his partner's front, tugging lightly on the straps that sat tight on his chest before slowly dragging downwards, his fingertips just barely skimming the surface of his tight leather briefs. "You look so damn good in this." His voice came again, this time from in front of him.

Bakugo couldn't help his feelings of disorientation as Kirishima groped at him from different angles, pacing around him and growling at him softly from all around him. "I can't wait to peel this off you piece by piece"

"Shit Eijiro, I can't- where- can you take this damn blindfold off me?"

"Why would I do that? You're so cute when you're confused, Katsuki." Kirishima's voice was dripping with lust and Bakugo shouted in surprise when he felt the strong hands of his lover shove him roughly from behind. Stumbling, he tried to right himself but ended up falling to his knees.

"God damn it you bastard, that hurt." Bakugo snarled, but the increasing tightness in his briefs proved he felt anything but anger at his situation.

"This is exactly where you should be." Kirishima's voice now uttered from directly above him and Katsuki let out a soft gasp as his hair was roughly tugged, pulling his chin up sharply to face what he assumed to be his lover's crotch.

"Mmm, fuck you." Bakugo growled, pressing forwards to the musky strain in the other man's pants. He could still feel Eijiro's large hands buried in his hair, and groaned when he was tugged closer, his face smashing into soft leather and the hard metal of what he assumed was a buckle.

"You want it so badly, don't you Kat." The voice above him was teasing and velvety, and only added fuel to the raging fire in the blonde's stomach. Bakugo couldn't help the moan that seeped from his throat as Kirishima began thrusting gently against his face.

Bakugo opened his mouth and lightly cupped what he could feel of his partner's length between his lips. He was shocked when his head was roughly yanked backwards.

"Hey now hothead, you're not allowed to do that." One hand freed itself from his scalp and trailed lightly against his cheek before coming to rest on his throat. "You don't want to be punished now, do you?"

"Your punishments are weak." Bakugo snarled playfully, fully aware of the consequences for his words.

"Weak?" Kirishima tutted, his grip tightening slightly on the blonde's throat and momentarily cutting off his oxygen. Bakugo grinned, rubbing his hands up the backs of Kirishima's legs and firmly groping at his ass. The large fingers around his throat tightened their grip at this and Bakugo let out a strangled gasp. "You really are pushing it, Blasty." The voice above him growled, fingers pressing down still harder. Through the blackness of the blindfold, Bakugo's vision turned to shooting spots of light and he felt a dizziness envelope him. This would have all been fine if he hadn't felt a brief shift shortly after, the slight pain startling him.

A swift three taps to Kirishima's ass was all it took to release him. Gasping and sputtering, Bakugo slumped forwards. He felt Kirishima's hands work the knot off his blindfold and was able to see the worry in the deep red eyes that greeted him upon his newly found sight.

"Sorry babe, was that too rough?"

Bakugo ran his hand experimentally over his throat before meeting the redhead's eyes again. "It's ok, I'm fine," he croaked. Nothing seemed broken, probably just a false alarm. Kirishima's eyes still held worry in them, so Bakugo leaned forwards, capturing his lovers lips in a sweet kiss. "I said, I'm fine, idiot." He said as he pulled away, a small smile tugging at his lips. "Weren't you going to punish me, Eijiro? I've been waiting all day."

The concern on Eijiro's face melted away into a look of familiar determination and Bakugo felt his cock twitch in its leather prison. "Stand up then, Katsuki." He commanded, and Bakugo rose. Grabbed forcefully by the straps on his chest, Bakugo was dragged behind the redhead. They moved around their bed, the stocks, and towards one of his favorite features in their dungeon. The throne of torment. The chair was large, black, and had a series of straps, chains, and leverage spots. The perfect seat to be fucked into oblivion.

Kirishima pushed him down roughly into the seat, snatching up his thighs and buckling them apart with the thick leather straps on each side. Bakugo could feel a fluttery feeling in his chest as his heart rate began to increase.

"Hurry up already, you spikey haired loser." Bakugo crowed teasingly, pulling tentatively on his restraints. Kirishima's eyes widened a bit at this, and in a swift movement he captured Bakugo's wrists and pulled them aggressively over his head, clicking the rings on his cuffs in place on the top of the throne.

Eijiro leaned his face in closer to the blonde, a more menacing light coming to his deep, red eyes as he grinned. "You really are being a brat today, aren't you. I'll have to shut up that pretty mouth of yours."

One of Katsuki's biggest turn ons was when his ever gentle and sweet Eijiro became incredibly rough, hard, and near threatening with him, an extreme side of him that most of the world had never seen. Bakugo dragged his tongue slowly over his bottom lip, his eyes darting down towards the obvious bulge in his partner's tight pants.

Hard... yeahhh.

Kirishima leaned back a bit, reaching into the large chest that he kept beside the chair. His incredibly sharp teeth twisted into a malicious looking grin as he pulled out a toy Bakugo was intimately familiar with. The red and black ball gag.

"I actually bought some new toys for tonight, but maybe I'll wait to use them." Kirishima mused, rolling the toy over his fingers before raising his smoldering rubies up to meet the blonde's gaze. "I want to be able to hear your screaming."

Bakugo chuffed out a laugh. His eyes locked intensely on the deep red orbs that were now mere inches from his face.

"I'd like to see you try, you- mmmh!"

With the ball gag strapped in place, Bakugo could already feel the saliva beginning to pool in the bottom of his mouth. "Much better." Kirishima growled, stepping back again to their chest of toys.

Bakugo couldn't move much in the situation he was in, but that was just how he liked it. His dark red eyes watched with anticipation as his fiancé's sculpted back and tight, leather clad ass moved in and out of his line of sight. He could hear his Eijiro as he rustled through their heavy oak chest, eventually coming up with a toy that brought a garbled groan of frustration from his lips.

The damn anal beads. Kirishima played with the large orange toy in his hand for a moment. His eyes traveling hungrily up and down the blonde's body, from the drool just beginning to run down his chin, the heaving of his strapped chest, and at last the tightly packaged bulge that so demanded his attention.

"You don't want the beads, babe?" Kirishima asked in a quiet grumble, turning his attention to the lube he was now applying over the incredibly thick toy. His eyes flickered as he looked down at the blonde, taking a few steps closer. "Even better."

Bakugo knew how much Kirishima liked his ass. It was part of the reason he always wanted to be the dominant one. He got so much sick satisfaction from watching him stretch over the enormous toys the two would buy. Eijiro also loved to see just how undone he could make him with only his fingers. Because Kirishima knew that Bakugo's dominant streak had one weakness, and the secret to that was unfortunately through his ass. However much Bakugo would deny it, Kirishima knew that he felt the most pleasure through his prostate.

"Let's take this off." Kirishima murmured, tugging on the briefs at the band. "I've waited long enough." Bakugo groaned his approval through the deep red ball that was forcing his jaw apart.

The briefs didn't get far down however, as Kirishima had already strapped the blonde's thighs apart. "Shit." He grumbled, and Bakugo snickered down at him. Eijiro's eyes flared up to meet his, his lips twisted in an irritated snarl. "Don't laugh at me, Katsuki. You'll regret that choice." The tearing of fabric caught Katsuki's attention and he yelped in surprise to see his partner's hardened hand making quick work of his black leather speedo.

A surge of hot arousal shot through Katsuki's body at the menacing power behind both his hands and his words. He tried to speak, but all that came from his throat was a lewd, muddled noise.

"You're in for it now, hot stuff." Kirishima growled, a wild grin contorting his features as he grabbed the blonde's member tightly, rubbing rough circles against the underside of the tip and causing his head to fall back against the chair with a noise of muffled pleasure.

Kirishima's other hand pressed firmly against the cleft of his ass, his thumb rubbing ever so slightly against his rim and pulling another garbled moan from his throat. His eyes burned down onto the red head, demanding that he move faster with a groan of frustration.

"So needy." Kirishima's voice chuckled from below. His finger finally entered, sliding in and out several times before adding the next. The slow burn quickly being replaced by a more pleasurable feeling. "Mmhhhhh" Bakugo's eyes rolled up slightly, his restrained body twitching and his hips thrusting slightly outward as his head pressed back into the dark cushion on the chair.

More... do it more...

Kirishima grinned up at him cockily, slipping his fingers out with a final scissoring motion, much to the keen of disapproval from the blonde above him. "I can't have you coming just from my fingers, now can I?"

Bakugo rolled his eyes, but found them quickly widened again in shock to the harsh slap to his ass he received as a result of his reaction. Kirishima instantly rubbed the spot before slapping again, harder this time. Small explosions burst from Katsuki's closed fists unintentionally and Eijiro looked up in amused surprise.

Bakugo would have growled something insulting had it not been for the thick gag halting his words. And even if he hadn't been wearing the gag, he was sure his words would have caught in his throat at the sudden thrust of the first three beads. A startled moan slithered its way around the ball in his mouth. His jaw had begun to ache, but that feeling was quickly outweighed by the pleasure of his prostate being rubbed by the second ball on the string.

"Kh-Khirh" The words were just barely intelligible as Bakugo thrust into the empty air in front of him, Kirishima's full attention on the increasing spread of Bakugo's entrance as two more balls settled into his ass. The burn was strong now, but as Kirishima began thrusting the balls in and out, a strangled noise came from his lips. An even larger ball was now rubbing the slick insides of his ass, his prostate sending hot ripples of pleasure through his twitching body with each thrust.

"Mmmhggh Khirishhh"
Bakugo's body was lit up in a tight hot fire that wrapped around him in a suffocating burn. He thrust forwards again, his heavy dick leaking beads of precum and his eyes rolled back against his drooping eyelids.

"What's the magic word, Katsuki?" Eijiro's voice crooned mockingly from below him, the thrusts of the balls becoming harsher and they sunk another ball deep, the burn of the first ball reaching his back tore an agonized moan from his lips. "Come on baby, I know you know it."

The sudden attention to his throbbing cock was what finally forced the please from his gagged throat.

"Plhs Khirihmuh!"

He cried out around the ball, his body shuddering, begging for release. The thrusts moved quicker now, loud squelching filling the room alongside the sweet noises of Bakugo's satisfied moans of pleasure.

His climax was blinding and Bakugo's hips jerked forwards in a few more shuddery thrusts as he came in thick ropes against the stone floor. Kirishima rose to a standing position now, the large balls still tightly gripped in the tight rim of his quivering ass.

He was embarrassed to hear the whimper that broke from his throat when he saw the expression on his lover's face. God, he wanted to be fucked again already just from that look. That look of pure dominance and power turned Bakugo on in just the right ways.

Kirishima unhooked the gag and Bakugo gasped, catching his breath more fully now. Kirishima looked down at him with a sideways smile, sliding his hand over his chin and wiping his drool on his tight leather pants. "Ready for round two, Kat? You're still kinda hard." Bakugo didn't trust his voice, so he nodded. Eijiro's eyes simmered at that, and he swooped down to press a soft kiss against the blonde's lips.

Bakugo watched as Kirishima moved back to their chest. Pulling out a small gold box that was unfamiliar to him.

These must be the new toys he was talking about.

He thought weakly to himself, his cock already beginning to harden again at the sight of Kirishima dropping his pants. Kirishima, with the box in hand turned back to face Bakugo, his own cock standing erect in front of him.

Kirishima looked down at him with a small smile. "Do you want to move to the bed? Your legs are trembling, so I think you might be tired of this position."

Leave it to Kirishima to be thinking about his wellbeing when all he wanted was to be fucked until the sun came up.
"Eijiro, I don't fucking care. Just get on with it already."

Kirishima paused, his features drawn in as he thought for a moment, then tucking the box under his arm, he moved a few steps closer to his lover. His hands moved quickly, first coaxing the large toy out of his ass. He moved slowly and bit by bit the beads left his ass, leaving him with an uncomfortable emptiness. Bakugo groaned, frustrated. His face mushed into Eijiro's bare chest as the redhead moved to undo his wrist restraints, and he was finally able to breathe as his hands fell heavily into his lap. He felt Kirishima's hands rub his thighs and groaned in distaste at the kiss pressed to his cheek before his thighs were unbuckled from their restraints. He shouldn't have been surprised when Kirishima lifted him, carrying him the short distance to their bed.

"I'm not some princess to carry, you moron." Bakugo snarled, leaning back into their mattress.

"I didn't trust your legs to walk." Kirishima said simply, opening the lid to the small box and pulling out what looked to be a thick, black wand.

The toy had a distinct hum to it that instantly made Bakugo aware that it was a quirk enhanced item. There was a little sex shop down in a smaller part of the city the two worked in that Kirishima particularly loved. The owner created toys that held magical qualities with the aid of his creation quirk. Most of the items in his shop were sex related, and the two often found themselves experimenting with various new items.

"Want to see what it can do?" Kirishima's voice held mischief to it as he flicked the little switch to the on position.

"Why the fuck not." Bakugo growled, but found his head abruptly thrown back with a cry at the touch of the wand to the side of his now heavy cock. A low, guttural scream tore through his lungs, his back arcing and body trembling violently at the force of the intense pleasure that overtook his body. His cock poured out against his stomach as he came almost immediately.

Kirishima took the wand off of him, and Bakugo opened his eyes slowly one by one in a disoriented squint, his quaking body trying desperately to come down from the sudden rush of endorphins.

God, his face is so close now.

Kirishima was leaning over him, rubbing his fingers over his abdomen and smearing the fluid over his skin.
"Well that went from one to one hundred really fast." His voice was awed, and he pressed a few quick kisses to Katsuki's jaw.
"F-fuck you." Katsuki gasped out at last.

"Guess that's why there's a cock ring." Kirishima's voice chuckled, "And level controls. Oops." But his oops was dark, and almost sinister.

Fuck, he did that on purpose?!

Katsuki glared up at him, opening his mouth to snap at him, but instead groaning at the thrust of Kirishima's cum slick fingers in his ass.
"I'm sensitive, you prick." Bakugo's angry voice whined. But he could feel Kirishima's mouth shift into a grin against his neck. "Not for long, baby."

Kirishima's fingers fumbled around his now soft and sensitive member before slipping the cock ring over him. And suddenly, it was as if he had been reset, no longer feeling the overly sensitive aftereffects of his climax. Kirishima pressed him back into the mattress, his gentle hands guiding him backwards and his cum slicked fingers pressing softly into his still loose hole.

"This feel ok?"

God damn Kirishima. Mother fucking Eijiro. Whatever you just did to my mother fucking body has made me ten times more horny now. Now is not the time to be coddling me you dipshit. My brain is so fucking whacked up I can't even see straight, just fucking get on with it!

"Katsuki? Babe, you ok?"

Did I not say anything? Damn it.

Katsuki sat up, swiping a shaky hand through his own sweat dampened hair. A small grin twisted his features as his trembling body and hormone induced raging hard-on forced him to utter the words he knew would cause his sweet Kirishima to lose every last shred of restraint. "Is that all you've got? Try fucking me like a real man, Eijiro."

Eijiro's eyes blew wide, his cheeks flushing and he was hastily snatched up by the red collar around his throat.
"A real man?!" He snapped, spinning him around and bending him in half with such a force that the wind was knocked out of his lungs.

"You just don't know when to quit, do you Katsuki?" His voice came from behind, the heat of his breath gusting over his cheek as he felt his partner enter him bit by bit.

"Oooh fuck..." Katsuki choked out, his eyes squeezing shut as finally he was given what he had wanted all along. Eijiro moved at an even tempo, his body pressing him roughly against the mattress as he thrust in and out.

"I'm going to use you like the whore you are." He snarled in a very not Eijiro-like way. Fuck, I really got him riled up this time. He was surprised at the sudden wrenching of his body as he was spun into a position of facing the looming redhead. The next thrust in sent his head back onto the mattress.

"I can't hear that pretty voice of yours Katsuki!"  Eijiro roared, slamming into him harder and harder by the second. Katsuki could only moan in response, his vision filling with sparks of light as he gazed through lidded eyes at his lover's rugged face.

"Not man enough for you?" Kirishima's voice rumbled, his ramming hips forcing Bakugo's entire body to shift up and down on their bed spread. Bakugo let out a broken moan, his body convulsing as Kirishima mercilessly rought the black wand down against his  throbbing cock.

The pleasure was intense and building as it had before, but now his climax was haulted. His body lifting higher and higher into a desperate surge of endorphins.

"F-FUUUCK EIJIRO!" His voice came bursting through him without restraint.

Kirishima's hips continued their driving, his arms pressing him down in a tight squeeze while his hands tortured him with the thick wand. Bakugo could feel his pleasure spiraling higher and higher, and his pitched moans were broken as his lover's deliciously sharp teeth sunk into the soft pale flesh of his shoulder.

"PLEASE EIJIRO!" Another tortured cry wrenched itself from his throat. His body was yearning desperately for release, his entire being thundering and shaking with force as he was abusively slammed back into the bed.

"FUCK EIJI! AH! PLEASE LET ME COME!"
Tears were streaming down his face, his palms detonating unintentionally as he scrabbled against his ruthless lover's hardened shoulders. Eijiro's hips were moving out of pace now, and his fingers fumbled in their dizzying ministrations. "FUCK, PLEASE EIJIRO, PLEASE."

It seemed to take just that for his lover to finish, and he spared no time releasing the blonde from the ring, his body reaching it's limit in a dry climax.

Bakugo didn't know how long he and Kirishima spent collapsed on top of one another in the bed, his body taking a while to come back from the intense overuse of endorphins. He was still trembling when he felt Kirishima's thumbs slide gently across the damp skin under his eyes. His lips pressing slowly down his cheek, his throat, and against the tender wound on his shoulder.

When he finally opened his eyes, he found those same worried gemstones gazing down at him, concern evident as he held him closely against his chest. "You ok McSplodes?" His voice was soft as he nuzzled against his throat.

"F-Fuck yeah, I'm fucking fine." Bakugo replied hoarsely. "Shitty Hair." Eijiro smiled down at him, his red locks flowing in soft tendrils across his shoulders as he leaned forwards and gently pressed their lips together. "I love you."

Bakugo smiled, his eyes slowly closing again from exhaustion. "You know I love you too." He found himself grateful for the man curling up next to him and pulling a soft blanket over their naked bodies. He was so lucky.

"Always." He murmured as he found himself succumbing to the warmth his fiancé was giving him.

"Always." He heard at last, and he let himself fall asleep.
