Work Text:
Shouto’s rather proud to be able to call this little stunt his idea.
He and Katsuki had been spending the evening in, catching up on the piles of paperwork left in the wake of their absent Mates. Izuku and Eijirou were currently halfway across the country, called upon for a joint team-up operation. These sorts of absences were nothing new to them; all four Pro Heroes had done their time away from home on occasion.
That being said…
This is the first time in a long time that Shouto has been truly alone with Katsuki. Not working together in the same room while their respective boyfriends were a room over, or at home waiting for them.
It’s just the two of them, in Shouto and Eijirou’s home, for an entire week.
Shouto’s eyes find their way to Katsuki multiple times throughout the night, finding him to be much more engaging than the stack of important files on the kotatsu top. Mismatched eyes traverse the hard curves of Katsuki’s shoulders, blessedly bare beneath tank top straps. They follow the line of that strap down along a swooping, loose neckline that does a piss-poor job of concealing Katsuki’s well-endowed chest.
The thoughts that enter his mind aren’t the first of their kind. There have been many occasions where Katsuki has barged his way into Shouto’s fantasies; as well as into Eijirou’s. Their sex life was more than thriving, fed regularly and rather vigorously. But curiosities have their place in the young couple’s life as well; many of which revolve around both Katsuki and his partner Izuku. Maybe that’s just the result of spending so much of their youth together. Maybe it’s the result of risking their lives and depending on one another so often.
Whatever the cause, Katsuki has always been a source of curiosity and desire for Shouto. And now he finally has a window of opportunity to explore him.
He reaches across the polished kotatsu top, slowly wrapping his fingers around the pen in Katsuki’s hand and plucking it right out of his grasp mid-stroke. The blonde turns to him with a sharply arched brow, a distinct lack of amusement in his eyes.
“Can I help you?” His voice comes out gruff, and Shouto’s sure he doesn’t mean to sound suggestive, but the gravelly tone it carries makes his stomach twist in that surprisingly pleasant way it does whenever he feels Eijirou’s large hands on his body. Shouto twirls the pen around his long fingers, mismatched eyes meeting that suspicious gaze.
“Mmm, no.” He gives a little shrug, lifting the pen between his lips to chew on it gently. He holds the other’s gaze, watches it slowly morph into something intrigued; attention flickering between an ocean storm and the tip of the pen disappearing between plump lips. Intrigue darkens into something heated, and Shouto knows then, in those burning cardinal reds, that he’s won. “But I can help you."
Understanding is the next thing to pass through those eyes, and then a vicious sort of grin curls at the corners of his lips.
“‘S that so?” Katsuki reaches across, taking hold of his pen again and pulling it away from Shouto’s mouth. “What’d you have in mind, hm?” He puts the pen to his own lips instead now, cradling the tip between his teeth. Shouto is acutely aware of the way the blonde has begun inching his way closer, their knees a hair’s breadth away from touching.
“I think you know, Bakugou.” Shouto moves to close the distance as well, sitting up on his knees to lean across the table. Their faces are inches apart; close enough to cinch the opposite end of the pen between Shouto’s own teeth. Katsuki’s grip on it is lax, so it takes no effort to pull it from his mouth and flick it away somewhere across the room. "And I think you want it."
The taunt barely passes his lips before Katsuki’s fists wrap tight in Shouto’s shirt collar and yank him the rest of the way. Their mouths collide with a harsh smack and the scattering, fluttering of their paperwork. Neither pay the fallen stacks any mind, not when the taste of each other is spreading across their tongues. Shouto moans at the oppressing sensation of teeth snatching his bottom lip, and the insistent probing of Katsuki’s tongue.
Kissing Eijirou can go one of two ways. Sometimes the redhead kisses Shouto like he’s something delicate, as fragile as porcelain and ten times as precious. Other times, it’s carnal: something animalistic, an all-consuming need. Kissing Katsuki right now is a lot like that second one, but more controlled. It’s a battle. Katsuki kisses the way he fights; strategic, efficient and deadly. Every move is made to exploit Shouto’s weaknesses, to get him to submit.
He would’ve submitted willingly regardless, but there’s something satisfying about having the choice, the chance to fight, and losing it.
Shouto pulls away just for a moment, relishing in the disappointed hiss that rumbles out of Katsuki’s throat. When the blonde goes to dive right back in, Shouto stops him with a hand on his sternum.
“Hey… I have an idea.”
“Agghhhhh, finally! My feet are killing me.” Eijirou grunts as he throws his body down onto the couch in their suite. He’s finally out of his hero costume, freshly showered and dressed in loose sleep clothing. Even with his eyes closed, he’s aware of Izuku shuffling around in his room, putting away his own hero gear to prep for his own shower. It’s been a long day, and an even longer mission, but at least they’ll get to go home soon. “Shower’s all yours Midoriya!”
“Thanks Kirishima!” He hears the other call back, and Eijirou slumps against the cushions, thankful for the way his body finally begins to relax. It feels like he hasn’t gotten to sit down in days.
As the shower switches on in the bathroom down the hall, Eijirou’s thoughts wander to Shouto and Katsuki. He wonders how they’re holding up. No doubt buried in the mountains of paperwork he and Izuku left behind for this mission. He sighs deeply, reluctantly pushing himself to his feet to cross into the kitchen for water. “Hopefully they’re having a better time than us.”
The night sky spills through the floor-to-ceiling windows of Shouto and Eijirou’s bedroom, illuminating the two naked bodies grinding against one enother atop pristine silk sheets. Shouto finds himself quite at home sandwiched between the hard planes of Katsuki’s torso and the soft bed, head thrown back on a moan he can’t stifle when teeth press into a faded scar on his neck. Eijirou’s teeth pierce rather deeply, and Shouto wears the permanent marks with pride. He already knows they’re blooming in dark pomegranate hues by the time Katsuki pulls off to leave another, a sinful tongue laving over his heated skin.
“You wanna try out what we talked about now?” He can hear the smirk in Katsuki’s voice as his lips brush the shell of his ear, and Shouto’s rushing out a breathless answer before he can even finish, barely audible in his desperation.
“Yes.”
“Yes?”
“Yes please~” He responds louder now, breathier and pleading as his eyes finally slip open to meet Katsuki’s. The hunger in those deep reds knocks the breath out of him, sends shivers racing up his spine along with a frosted puff of air. His hand slides out, fumbling blindly for the bedside table to pull the drawer open. It takes a few grabs to find what he’s looking for, and a grin spreads across his kiss-bitten lips. “Let’s use this, yeah?”
Katsuki had turned away for a moment to set up Shouto’s laptop on the foot of the bed, angling it just right before putting in a call to Izuku. As he turns back, his eyes go wide with surprise at the item in Shouto’s hands. “Sure,” he can’t agree quickly enough, leaning back over Shouto to sweep him up in another kiss. His hands make their way down his body as well, toying with Shouto’s prepped little hole. He'd had the forethought to prep himself before jumping Katsuki's bones, of course.
The video chat tone rings, drowned out by Shouto’s soft whines and pants, along with Katsuki’s own gasps as he fingers himself open with ease.
Izuku and Eijirou are sure in for a surprise...
“Todoroki-kun is calling me? At this hour?” Izuku, freshly clean and dressed himself, peers curiously at his laptop screen, then glances over to Eijirou. It’s odd that he’d call him rather than Eijirou… “Did something happen with Kacchan maybe?” Eijirou makes his way over from the couch, refilled water bottle in hand. Leaning over Izuku’s shoulder, he looks down at the screen, huffing a little laugh at the ridiculous little icon the other hero has set for Shouto.
“What even is that icon?” It’s the cutest thing; Shouto’s facial features look a little smooshed together, his nose missing. He’s seen popular videos with filters like those, but it’s even more comical and endearing on his lover.
“O-Oh! W-Well, it was just a filter app he had on his phone… We messed around with it a bit.” Izuku explains, his fingers quickly scrolling along the trackpad to accept the call. It takes a moment to load, but when it does, Eijirou’s dropping his bottle, and Izuku’s dropping his jaw.
“K-Kacchan?!”
“Shouto??”
“W-W-W-What is this???”
“What does it look like, dumbass?” Katsuki is the first to respond, breaking away from a kiss with a wet smack. He and Shouto’s bodies are on full display; entirely naked, hard, and flushed with arousal. Shouto’s more than a little breathless, panting into Katsuki’s neck and shivering as Izuku and Eijirou’s shocked expressions and voices come through the computer screen.
“Ah…” They both look so caught off-guard, and Shouto can’t help the small little laugh he lets out at Eijirou’s face in particular. He recognizes the look in his eyes all too well; eyes wide and pupils slowly beginning to dilate. Even Izuku’s speechlessness fills him with a little bit of satisfied confidence, Katsuki even more so, given the way he twists around, moving to half-straddle Shouto.
“Hey there, Fuckers, welcome to the Night Show~” With the biggest shit-eating grin Shouto’s probably ever seen the blonde wear, Katsuki brandishes the toy of their choice; a double-ended dildo, green at one end and red at the other; Izuku and Eijirou’s colors.
He swears, he never planned this that thoroughly.
“O-Oh fuck—” Shouto whines softly when the slick, blunt head of the toy presses against his hole. He bites down on his lip, eyes slipping closed and head falling back as it pushes inside. At the same time, he can feel it slide inside of Katsuki, and heat rushes through him at the debauched sounds that pour out of his filthy mouth. Their cocks rut together as they grind on the toy, Katsuki’s hand keeping it firmly in place until they get as much of it inside them as they can. Once it’s fully seated, Katsuki reaches to stabilize himself on the bed, groaning softly against the side of Shouto’s neck.
Shouto’s hands slide up into soft blonde spikes, tugging teasingly as his lips ghost over the edge of Katsuki’s cut jaw, gaze fluttering over his broad shoulder and straight into the camera. A lewd little moan filters out of him when the toy jostles with Katsuki’s movements, pressing against that sensitive spot inside him.
“W-We missed you…” He bites his lip, clinging to Katsuki when he starts to move.
“Holy fuck, Shou..” Eijirou can’t tear his eyes away from the screen. Izuku covers his mouth with one hand, while the other situates itself somewhere suspiciously low on his body, too shocked to speak, and clearly too horny and embarrassed. “All this for us?” Eijirou leans in a little closer, uncaring of his close proximity to Izuku, wanting to watch it all. “How sweet of you~ Was this your idea, Shou?”
“M-Mmm—HMM—” Shouto moans mid confirmation, his legs trembling where Katsuki’s body keeps them held open. “B-Both of us, wanted to..” He rushes out, reaching down to grasp at Katsuki’s hips. He’s gotta hold onto something as the blonde starts upping the pace. Katsuki glances back over his shoulder at the camera as his hips roll nice and slow, letting the toy slip out a little before he rocks back down on it, knocking a moan out of Shouto as well as himself.
“Shoulda seen him, Shitty Hair. Your boyfriend’s a nasty little slut—nnghh fuck yeah—” He bites his lip, back arching to let the toy hit the spot it just brushed again. “Jumped me tryin’ to work.”
“Mhmm, he does that.” Eijirou hums, voice dripping with a simultaneous arousal and admonishment. “I’ve tried to break that little habit of his, but I think he likes when I put him over my knee.” Shouto moans out loudly at that, shivering a little harder as Eijirou’s voice filters through; effortlessly sexy and commanding.
“Freaks.” Katsuki huffs a derisive little laugh, before throwing his gaze back at the camera. “And you, Deku?? Did ya fuckin’ die??” Izuku’s only response is a shocked little squeak, hands still pressed firmly over both his mouth and his crotch. Eijirou relays just that to them too, eyes slowly dragging over Izuku’s flushing skin, lingering over his lap.
“Oh, I see why you never let him rest now, Bakugou.” He teases the other able to see the outline of his semi through his sweats despite his efforts to cover up. He’s thick.
“Best fucking dick, that’s why.” He groans, sounding progressively more and more breathless the longer he and Shouto fuck themselves on this toy. Their cocks are leaking, slicking up the glide against one another as they rut like horny teenagers. “I love feeling it the next day, love feeling split open on it~” Katsuki cackles at the choked sound Izuku makes in response; a cackle that quickly breaks down into a moan.
“Mmm, that sounds familiar, doesn’t it Shou?” Eijirou hums, reaching down to palm himself with a short hiss. "Isn’t that what you like to say to get me to fuck you before patrol?"
"Oh my god—" Shouto chokes on a moan, hips rolling almost violently down onto the toy. “K-Katsuki—faster please—" Katsuki nods, working his hips in time with Shouto’s.
“Yeah, yeah fuck, that’s good,” Katsuki’s head drops down against Shouto’s neck, panted breaths fanning over his warm skin as they move together. “Fuck!”
The softest little whimper leaves Izuku’s mouth then, the first sound he’s made other than the previous shrill little squeak. When Eijirou glances over, he can see the heel of his hand grinding down against his cock, and he grins, leaning in close to Izuku’s ear.
“C’mon, you like what you see, right? Let ‘em know how much you’re enjoying the show.” Eijirou goads him on with a grin, nipping at the edge of Izuku’s ear before grabbing the laptop. Carrying it gently, he brings it over to the couch and sets it on the coffee table in front of him. Now that he’s sitting comfortably, he reaches down to palm himself again, stroking along the print of his cock in his grey sweats. His eyes meet Izuku’s stunned eyes from across the room as well, and he grins, nodding toward the couch to beckon him over. It’s almost comical, the way Izuku scrambles over to sit beside him. Though he still shyly hides. They’ll have to fix that.
“M-Midoriya…” Shouto whimpers softly, nails curling into Katsuki’s hips as he finds him on the screen again. “Y-You like it, right?” He puts on the best pouty, kicked-puppy voice he can manage with Katsuki fucking into him the way he is, his eyes glassy and tear-filled from the pleasure.
“Of course! I.. I just…” Izuku stumbles over his words, fingers nervously pulling his shirt down over his lap; another lame attempt to hide his erection from them. Not that it does him much good, with the size that it is.
“Get over yourself you lame fucking nerd!” Katsuki grunts, sinking down especially deep on the toy. “What happened to all that brave talk, huh? What happened to the Deku who fucks me so hard I have to fly everywhere, huh?!”
“Th-That’s enough, Kacchan..” Izuku flusters, face going bright red at the filth Katsuki spews. But Eijirou can see something else happening too; he can see the light fading from those bright green eyes—can feel it be replaced by something far darker.
“I didn’t think you were such a pussy.” Katsuki goads and goads, fucking himself harder on the toy to hear Shouto moan and cry for it.
“I said that’s enough, Kacchan.” Izuku’s tone becomes something much harsher all at once, and Katsuki seems to shiver under the weight of it, nearly collapsing on top of Shouto like the air’s been knocked out of him. Cardinal red eyes go wide, breath trembling out of his chest as his hips start working faster. Shouto clings tight to him, writhing on the toy filling him repeatedly.
“Ooo,” Eijirou hums, shivering a little bit himself at the sudden switch in tone. Izuku is no longer hiding himself either, eyes fixated on the screen. More than a little turned on by the display, Eijirou reaches over to gently grasp at Izuku’s cock through his shorts, giving it a firm squeeze and relishing in the surprised moan that punches out of the other. “That’s it, go on and watch~ I think they both liked that just now.” Eijirou’s teeth scrape against the side of Izuku’s neck, hand working its way inside his baggy shorts and his boxers.
“K-Kirishima—” Izuku gasps in shock, hips immediately rutting up into the redhead’s hand, groaning quietly as fingers wrap around him and squeeze, tugging on him in slow, delicious pulls.
“Shh, eyes on the show.” Eijirou’s free hand comes up to grab Izuku’s chin, turning his head to keep his attention on the screen, instead of him. “He’s so hard, just from watching you both.”
“Yeah, I bet,” Katsuki’s breathless already when he speaks this time, sounding much more wrecked as he and Shouto continue to pleasure themselves with that toy. “He likes wa-watching..”
“E-Ei..” Shouto whines, toes curling on a particularly good thrust. “Ei, t-touch yourself too..”
“Want me to, Baby? Does it get you hot knowing I’m touching myself, getting off to you getting fucked the way you like it?” Eijirou adjusts himself on the couch now, right hand buried in Izuku’s shorts while his left works to shove his own sweats and boxers down his thighs, freeing his cock from its confines. His fingers wrap around it, giving it a nice, firm stroke.
“Y-Yes! Yes, fuck yeah—Katsuki—" Shouto begins to shake, already able to feel his orgasm build, winding tight inside him as their bodies move faster, spurred on by their lovers on the other end of the call.
“Look at ‘em Midoriya… Fucking each other to the thought of us.” Eijirou huffs, groaning through a particularly tight stroke, while squeezing a similar noise out of the man beside him with a twist of his hand.
“Kacchan’s always been a-a good whore… I’m surprised at Todoroki..” Izuku barely manages to breathe out, hooded eyes fixating on the screen, specifically at the double-sided dildo plunging into their lube-slick holes. Katsuki moans louder at the name Midoriya calls him, and just like Shouto, he can feel himself quickly approaching that edge.
“Fuck fuck fuck not gonna last—” Katsuki hisses between his teeth. He doubles down with his fists in the sheets, arching his back and rolling his hips faster, chasing the pleasure that’s rapidly mounting for them both. “Fuck, gonna cum, fucking—”
Katsuki’s mantra of curses is broken by Shouto’s own moans, their voices overlapping one another in a cacophony of ecstasy as they climb that peak together. Eijirou and Izuku watch on, Eijirou’s hands working both of their cocks while Izuku leans over to mouth and kiss at his neck, free hand reaching down to squeeze and roll Eijirou’s balls in his palm. They’re not going to last much longer themselves, and Eijirou is the one to goad them on for the both of them.
“Cum for us, you two.. Go ahead and cum, pretty boys.”
Their orgasms crash into them all at once, mirrored cries pouring out of them as their bodies slip into a frenzied sort of pleasure. They fuck back mindlessly onto the toy, backs arching tight and cum splattering between both their chests. A burst of flame ignites at Shouto’s right temple, but luckily Katsuki’s arched up so tightly that he’s nowhere near the baby flame that disappears nearly as quickly as it came.
Eijirou and Izuku aren’t far behind them, moaning out their names as their releases splatter all over their clothes, dripping over Eijirou’s knuckles and soaking his fingers.
For a long moment, the only sounds that pass through the call are heavy pants and soft, wet sniffles. The rustle of sheets and clothes brings a shred of awareness back, and Eijirou slowly lifts his head back toward the screen.
“You two okay?” His voice sounds gravelly, especially through the speakers, but slowly, Katsuki lifts his head to nod, the muscles of his upper body trembling as he moves in his post-orgasm haze. Shouto is limp and pliant beneath him, giving only a soft whine when Katsuki removes the toy from them both, tossing it aside to deal with later.
“Mhmm.. Fine..” He grunts, slowly moving to lay down beside Shouto. It takes a moment more for the other to move as well, though it’s just enough to curl up into Katsuki’s side.
“Felt so good..” Shouto hums, a smile spreading across his face. “Did you enjoy the surprise?”
Eijirou laughs at that, soft and breathy, before turning to Izuku, who’s barely begun to return to the world of the living.
“Mhmm, we did.” Eijirou leans back on the couch to gently rouse Izuku. “Right, Midoriya?”
“Yeah… It felt so good to relax like that… Thank you both.” Izuku hums in reply, smiling sleepily. “You two rest now too, okay? Drink some water, too.” Katsuki rouses, lifting his head to squint at the screen.
“Okay, Mother.” He huffs, tone dismissive, but only in the playful way that Izuku recognizes. Offscreen, they can hear the crinkle of the plastic bottle Katsuki ends up reaching for.
“We’ll call in the morning, okay? Have a good night’s sleep.” Eijirou adds, heart a little sore that he can’t be there to have post-sex cuddles with Shouto.
Soon, though. Soon.
"Good night."
