Work Text:
Katsuki is standing at the kitchen counter making himself a cup of tea when he hears a creak by the front door. With a keen sense of hearing that comes only with being a weary hero, he listens to the quiet swing of the door closing and even quieter shuffling of boots being taken off. That means it’s who he was hoping it would be. After ten weeks away, Eijirou has finally come back home.
Not that he’d ever admit to being sappy or whatever but— Eijirou’s absence left a hole in the apartment. As much as Katsuki loves Shouto and his tendency for silence, sometimes Ei’s bubbly personality is hard not to miss once it’s gone. The days without him were dim in comparison to the three of them being together and Katsuki can tell how much Shouto felt it too. Whether it be during intimacy or in passing, an element always felt lacking. Like a lost limb.
Katsuki can feel his heartbeat quicken and he physically reels himself in before acting like a fool in front of his boyfriend. He waits by the counter and makes a clink with his spoon— a deliberate act that signals Ei who is waiting for him and where. He counts to five until Ei finally rounds the corner into the kitchen. Out of the corner of his eye he can spot Eijirou's ruffled look and loose clothing, meaning he’s dead tired and ready for bed. It is late after all.
Barely sparing a second, strong arms come to wrap around him from behind. Unconsciously, Katsuki relaxes into Eijirou’s hold while the latter sighs into his hair.
“Mmm. It feels so good to have you in my arms again,” the words murmured into the crook of his neck.
Katsuki subtly shivers before responding, “Oi. don’t fall asleep on me even though you missed me so much, dumbass.”
He turns in Eijirou's hold and goes to grasp his face in his hands, inspecting closely. There are dark circles underneath his eyes and his hair is loose, giving the shape of his face a softer look. “Did Fatgum have you working 24/7 or what? You need a shower and bed stat, Ei.”
“Just gimme a minute. And no, Fatgum didn’t overwork me babe, I just missed you guys too much to sleep well.”
Eijirou leans forward and buries his face in Katsuki's neck again, tightening his arms around him. Katsuki may be emotionally constipated most times but never enough to not care about the wellbeing of his idiots.
“Ei… shit— do you wanna talk about it? The case? I know you were told to keep it under wraps while you were there but if you want to— I don’t know— tell us about it, you can.” He can feel Ei’s smile against his skin.
“It’s alright Kats. It wasn’t about the case. I mean— it was, but I don't really want to talk about that right now. I just wanna be with you guys and cuddle if that’s okay.”
“Fuck of course it is baby. Listen, I’ll go fill up the tub for you and you go fetch something comfy, preferably Shouto’s clothes since all his shit is stupid soft.”
“Mmm okay. Where is he anyway?”
“He's asleep in bed. He wanted to wait for you but fell asleep reading… he’s probably gonna be all pouty and shit when he sees you.”
“I’ll go see him before I go clean up,” Eijirou gives him one last squeeze before he pads to their bedroom, being as quiet as can be despite going to wake Shouto up with his presence anyway.
Katsuki sets off to the bathroom and once he has the tub full at the right temperature, he wanders into their bedroom and walks into a sight he would admit is cute as fuck.
Eijirou and Shouto are bundled together underneath the blankets and Shouto is very much still asleep, with Ei joining him very soon in dreamland. They’re facing each other with Shouto’s head nuzzled in Ei’s chest, both of them clutching each other tightly. Katsuki bets that Sho doesn’t even know it’s Ei yet. He's probably dreaming of cats jumping through clouds and thinks Ei’s chest is the soft belly of a kitten or some shit.
Katsuki doesn’t have the heart in him to break them apart and send Ei to the tub. Instead, he lifts the covers and crawls in right behind shouto, wrapping his arms around the two of them gently. God, he missed this so much. He feels whole again.
Sensing one more pair of arms than usual (at least until recently), Shouto stirs awake and blinks open his eyes to the sight of Ei and Katsuki cocooning him.
“Eiji? When’d you get home?” Shouto mumbles and Eijirou’s eyes flutter open at the sound.
“Just now, love. Came straight home to you and Kats,” he murmurs and if possible, buries himself closer to them. He starts kissing Shouto’s collarbone while his hands caress Katsuki’s waist.
Shouto hums happily and shifts in their embrace, turning onto his back so he can see and feel both of them at the same time. He looks at Katsuki through half-lidded eyes and tilts his head chin up to ask for a kiss. Katsuki huffs a laugh at his cuteness and presses a soft kiss to even softer lips, parting only when Ei says huskily, “I missed you both so much.”
Shouto turns his head and captures Eijirou’s lips next, starting off slow and quickly getting heated. He pulls away to whisper, “We missed you too, Eiji. We’re so happy you’re back home and safe. Can you stay in bed with us all day tomorrow? Please?”
Katsuki almost scoffs at Sho asking for such a request without even consulting him but he realizes he also wants that too. And damn him that Shouto always knew what Katsuki wanted, before he even knew it himself. Ei does too. That’s why he loves them both so much.
“You don’t have to ask me, Shou baby. I can stay as long as you both want. I don't ever want to see an international mission document on my desk ever again. In fact, I won't go into the office until next week. Is that okay with you two?” Ei grins softly.
“You don’t have to tell me twice,” Katsuki mutters, not bothering to hide his wants like other times. Ten weeks aways was too damn long. For all of them.
Shouto starts trailing kisses down Eijirou's neck and Katsuki relishes in the way Ei’s breath stutters and body shivers. He was always sensitive. Katsuki can’t keep himself from kissing him any longer. He holds Ei’s face between his hands and presses a deep kiss into his mouth. He can’t believe he went so long without kissing him. He should’ve done it the moment he stepped into the kitchen.
Ei’s trapped between the two of them now, with Katsuki pressing kisses into his mouth and Shouto slipping his hands under his sweatshirt to rub at his nipples.
“Mmm— take off your shirt Eiji. now now now,” Shouto quietly demands and Eijirou gasps.
“Shit I— I haven’t showered yet—”
“If you make us wait more than the ten weeks you were away, I’m gonna be fuckin pissed Ei,” Katsuki growls, and hears Shouto agree.
“Eiji please,” Shouto whines breathily and Katsuki can see the exact moment Ei makes up his mind to leave his bath until afterwards. His pupils dilate and he immediately presses forward to lick into Shouto’s mouth and the sounds Shouto does are too fucking beautiful for Katsuki to not get hard under a second.
While Eiji takes his time unraveling Shouto with his kisses, Katsuki gives himself the task of undressing Sho and Ei. He lays stray kisses on the shoulders of both of them and his hands find slender hips that are rolling faster by the minute— signaling how affected Shouto is.
He slowly slides down Shouto’s shorts and discovers him without underwear, which means this fucker was probably planning this from the start. Judging by how wet he is, he’s been thinking of this way before Ei got home, maybe even prepped a little judging by the shine of lube on his ass. Fuck.
He moves over to tug at Ei’s sweatpants and throws it in a corner of the room. He then lifts his own shirt over his head and kicks his sweatpants off as well. There, now everyone is a decent level of naked.
Watching Sho and Ei continue to make out may be his favorite pastime but right now he wants to do the next best thing he enjoys. Shouto’s beautiful cunt is calling his name.
He can tell Shouto was completely lost in his makeout with Ei that he jumps and moans when Katsuki leans forward and licks him flat across his pink and puffy lips. Just to be a little mean, he gives a harsh suck to his clit too.
“Aah— ‘Suki,” Ei breaks away from Shouto’s mouth to look down and gaze in adoration at the sight of Katsuki between Shouto's legs.
“Is he being mean to you baby?” He croons, littering kisses all over Shouto’s face. “Want me to tell him to stop? You like it don’t you? When Katsuki’s a little mean with your pretty pussy?”
Sho moans louder at that and his hips stutter in Katsuki’s grasp. He doubles down and starts eating Shouto out in earnest, licking and sucking at Shouto's most sensitive areas.
“What do you want, baby?” Ei continues, tweaking Shouto’s nipples under his flimsy shirt, “while Kat makes you come in his mouth, what do you want me to do?”
“Ah, ah. In my mouth. Please, Ei. Give it to me.”
Ei swears under his breath and quickly rearranges himself to bring his hard cock to Shouto’s kiss-bitten lips. Eijirou groans and Sho hums simultaneously as he leans forward to lick Ei’s tip. He wastes no time and pushes himself to swallow the rest of Ei down, making him release a guttural moan.
Katsuki kinda wants to make a personal competition here. He isn’t anything if not determined alright? He wants to make Shouto cum before Ei does, which means he needs to start pulling out all the stops, judging by how sensitive Ei seems to be right now.
He leaves one hand pressing Shouto’s hips to the bed and has the other lightly caress the inside of his soft thighs, making him twitch. God he can feel how slick the back of Sho's thighs are, and his rim, too. Katsuki slowly brings his thumb to rub at Shouto’s hole as he continues sucking and nipping at his clit.
The way to win Shouto is usually the long game but tonight they’re all extremely sensitive and pent up. He can tell. Even though he and Shouto fucked a lot while Ei was gone, having him back seems to have ramped up the urgency and sensitivity. Without warning, he sinks two fingers into pulsing heat and hears Shouto’s muffled moan around Ei’s cock.
He pulls his mouth away from sucking marks on Sho's angel soft thighs and starts fingering Shouto steadily, while moving his other hand to gently spank Shouto’s clit and puffy lips.
“Look at you sweetheart,” Katsuki murmurs, “you’re taking Ei’s cock and my fingers so well. You gonna make him cum? You wanna swallow everything he’ll give you?”
Katsuki can see the tears gather on Shouto’s long eyelashes as he nods the best he can. He pulls away from Ei’s dick and a string of spit connects them together.
“Please Kats. Make me cum—make me cum.”
“I love when you beg so prettily,” Katsuki groans and starts petting Sho's clit harder while adding a finger in his pussy. He can feel Shouto practically soaking the bed. Ei groans at the sight.
“C’mon baby, cum for me. Show Ei what a good boy you’re being, taking us both so well. Go on— put him in your mouth while you’re cumming on my fingers.”
Shouto whimpers and stretches his lips around Eijirou again as Katsuki curls his fingers just at the right spot. Shouto’s back arches and he cries out and cums, throat and pussy convulsing around Katsuki and Ei in tandem. Katsuki continues gently spanking Shouto's oversensitive cunt, and the lewd sound is nothing if not glorious.
Katsuki sees Ei grab himself by the base of his dick as to not cum, and pulls himself quickly out of Shouto's mouth.
“What are you waiting for?” Katsuki looks at him with an eyebrow raised as Shouto slumps down on the bed between them.
“I wanna cum in him. Please. I only have one load in me tonight. I need to be in him now.”
Katsuki grins wolfishly and says, “Well don’t let me stop you. He’s prepped and ready to go sweetheart. He’s been waiting for you to fuck him ever since you left. Don’t hold out on him now.”
Ei whimpers and grabs his dick tighter, willing himself not to come at the thought of Shouto’s hole waiting for him the entire time he was away.
Speaking of Shouto, he lifts his head and blearily says, “I want you both. At the same time. Now. No more wasting time. Please. It's been too long.”
Katsuki and Eijirou share a helpless and fond look before each one of them rushes to one of Shouto’s sides.
“And you’ll get us baby,” Katsuki soothes, “you have us right here, we’re gonna fill you up so good, won’t we Ei?”
“Of course we will. Look at you, being so good for us. I’m gonna fill your pretty ass with cum while Katsuki fucks your cunt. You’ll be able to feel us for days afterwards, love.”
Shouto whines, high and throaty in the darkness of their room. “Please please please,” he begs.
Ei presses his thumb into Sho’s rim and discovers him prepped already. It seems he’ll have to ask Shouto about that later. Luckily for him, it looks like he can dive right in. Eijirou looks up and nods at Katsuki, signaling him so they both sink into Shouto at the same time.
“Fu-uck” Shouto gasps as they both press forward and bottom out. His tongue is lolling out of his mouth as he pants, sandwiched between his two favorite people in the world. His leans his weight back on Eijirou, head cushioned on his broad shoulder while Katsuki holds him steady by the hips.
Katsuki leans forward to start sucking at the spot behind his ear and Sho clenches, making the two men moan in unison. “Are you ready for us baby? You know once we start, we won’t stop until we cum.”
“Yes yes yes. Move now,” Shouto chants and Katsuki and Ei both pull out and then slam back in, making Shouto cry at the sudden feeling.
They fall into a punishing rhythm, with Eijirou and Katsuki taking alternating thrusts into Shouto. There's not a single moment he’s empty. He wouldn’t want it any other way.
“Fuck Sho, you’re so tight baby. I missed having your gorgeous ass wrapped around my cock. Look at you,” Eijirou grabs fistfuls of Shouto’s ass and spreads the cheeks apart, thrusting deeper into Shouto.
“It’s like your body was made for us wasn’t it sweetheart?” Katsuki pants, “your asshole and pussy made to take me and Ei and no one else. Isn’t that right?”
“Ye-yes, yes, more,” Shouto is so close, a little push and he’ll be right there.
“What do you say I fill you up huh baby? I fill you up with my cum and breed you right here. You’d like that. You want all that cum pouring out of you?”
Shouto cries and nods his head, fucked speechless. Ei thrusts start getting sloppier, and Katsuki grabs his face to bite at his mouth.
“What do you say, Ei? Let’s fill him up so good huh? Let's give this pretty boy everything he wants. He wants us all to himself. It would be a shame to disappoint him. C’mon baby, cum for me. Cum in our baby boy’s tight ass.”
“Hah. Mmm yes Kats please I’m— I’m cumming–oh,” Ei spills into Shouto as Katsuki starts sucking on his tongue and thrusting harder into Sho’s pussy.
Shouto is moaning at the feeling of Eijirou's cum and Katsuki just has to thrust once—twice more, until he pinches Shouto’s clit one last time and feels Shouto gush and clench around his dick unforgivingly.
“Fuckkk,” he groans and the feeling of Shouto squirting around him has him pushed over the edge. He can’t remember the last time he came so hard.
Shouto becomes limp in their embrace and he whimpers when they both gingerly pull out of him. They stare down hungrily as Shouto drips their cum onto the bed sheets until they hear his huff of breath from above.
“Stop looking at your own cum and come kiss me,” he whines, tilting his head at both of them.
They both lean forward and shower Shouto with soft kisses, unable to stop. Shouto giggles and has to push them away because he's so ticklish.
“I don't ever want to be apart from any of you for that long again,” Shouto says quietly. Ei turns to look at Katsuki helplessly and Katsuki shrugs back at him.
“I guess if Shouto orders it, we must abide by it,” Katsuki grins, “I, for one, support that idea… We missed you too much around here, Ei.”
Eijirou’s face gets even softer and his eyes get glassy. He throws his arms around both of them and sniffles. “I won’t, I promise.”
They stay in their little group hug of cum and tears for a few minutes until Katsuki has enough.
“Okay, how about that bath now? The tub's big enough for all of us. Let’s go. We’re filthy.”
“You have to carry me,” Shouto pouts and Ei easily scoops him into his arms.
“Okay losers. Bath time and then bed. I don't want to hear anything else until I have eight hours of sleep,” Katsuki grumbles. He's so glad they all scheduled the day off tomorrow. “And no asking for breakfast early either.”
“Can I have waffles for lunch then?” Shouto’s voice carries from ahead of him.
“I want some too please. I missed your cooking, Kats.”
“Fucking fine.”
He’s glad his home is whole again.
