Work Text:
Katsuki and Izuku stand on the front porch, leaning against each other as they watch the small, silver sedan pull out of the driveway. They wave, broad smiles on their faces, until the car disappears around a bend in the road and they can no longer hear the rumble of its engine.
“She’s… she’s really gone. I can’t believe it. Our little Eri is finally gone on her first sleepover…” Izuku wipes at his eyes, sniffling like the proud father he is. Although she’s already eight years old, Izuku and Katsuki only adopted her three years ago. She had become attached to her Daddy and Papa immediately, but was much more wary of strangers. It hadn’t been until this year that she’d finally invited a friend for a sleepover and now finally she’s spending her first night away from home.
Katsuki punches his husband on the arm, blinking away the tears in his own eyes and pretending they were never there. “Oh, calm down, you big baby. She’ll be fine. She’s a tough kid. And besides… you know what this really means for us, don’t you?”
Izuku cocks his head to one side, feigning innocence. “Well… I suppose we’ll be all alone for the evening, without interruptions and able to make as much noise as we want. Did you have something planned? Maybe my Kacchan wants to play video games?”
“Well, hey, if you want to play with my joystick, baby… I guess I’ll let you.” A lascivious grin spreads slowly over Katsuki’s face and he licks his lips.
“Oh, you’ll let me, will you?” Izuku teases right back, crowding closer into Katsuki’s space. They stare each other down, Katsuki tilting his chin up to look his husband in the eye. The shitty nerd had hit a giant growth spurt at the tail end of high school, while Katsuki on the other hand… he’d made it to 5’9”, but only if you rounded up from a quarter inch. Finally, Katsuki launches himself into his husband’s arms, trusting Izuku to catch his weight. Izuku does, holding Katsuki up by his thighs and shoving them both inside the front door.
As soon as he hears the latch click, Katsuki is licking and biting at his husband’s neck, rolling his hips against Izuku’s belly and clutching at his frizzy mop of green hair like a drowning man to a piece of driftwood.
“Hah… God, yes, baby…” Izuku moans, doing his best to kiss back. “I need to get my mouth around you so bad… Let me take you upstairs, please? I just wanna suck you. Please, Kacchan…”
“No, too far. Go to the couch. No more waiting!”
Then Izuku is stumbling backwards through the front hallway, avoiding the kicked aside rain boots and the tiny, sparkling Mary Janes that Eri insisted they buy her but finds far too uncomfortable to wear. He makes it all the way to the coffee table before disaster strikes. His foot lands in something sticky, wet and cold that squishes up between his toes. He yelps in surprise and promptly drops his husband onto the plushly carpeted floor, scrambling back to see what horrifying thing had attacked his feet.
“Mother fudger! Deku, what was that for?!”
“I think Eri left out her rice pudding from dinner and I stepped in--- Wait, Katsuki, did you just call me a mother fudger ?”
“I…” Katsuki looks more dazed from the betrayal of his own tongue than from being dropped from the considerable height of Izuku’s arms. “I’ve just had to watch my mouth so much lately, I guess I’m not used to cursing anymore. What a bunch of bullhonky…”
Izuku is now lounging back on the couch, surreptitiously cleaning his foot with one of the wet wipes from Eri’s “eating messy food at the couch” stash. He gives his husband an appraising look. “Well, then come on over here, baby, and I bet I can wring some swears out of you.” He pats the seat next to him and then slides down onto the floor, blinking up at his husband with faux-innocence.
Katsuki throws himself onto the faded gray cushions, spreading his legs wide as he pulls himself out of his black joggers. “Oh, yeah? Gonna remind me what that filthy mouth of yours can do? Get over here…”
Izuku settles himself between his husband’s thighs and starts to kiss at them before he decides to fuck teasing and go straight for the kill. He sucks Katsuki’s half-soft length between his lips, coaxing it to full hardness. His eyes roll back in his head as the salty-sweat taste of cock hits him. He swirls his tongue around the head, reacquainting himself with the weight of it in his mouth.
“There’s a pretty fucking picture…” Katsuki purrs above him, running his hand over the fuzz of his husband’s buzzed undercut. He resists the urge to buck up into Izuku’s mouth, to hold him down and fuck his face until he chokes. It’s been so long, surely Izuku wants to ease back into things, but no… the fucker is pulling on his hips and whining around his length, practically begging to be taken. Katsuki isn’t sure why he’s surprised. Izuku’s always had a masochistic streak.
Katsuki wraps his hand around the back of his husband’s head and grabs ahold of his green curls. He pushes Izuku down and rolls his hips, languishing in the wet heat of that red mouth. Izuku’s eyes flutter closed and he goes lax, content for the moment to be nothing more than a fuck toy, a hole for Katsuki to thrust into until he spills, his belly nothing more than a place to keep the mess. He can feel his dick throbbing against his thigh and he sneaks a hand down to palm at himself through the fabric of his sports shorts. Katsuki doesn’t even notice, and there’s a sick sort of joy in knowing that he’s getting off without even getting permission for it.
On his next pull, Katsuki holds Izuku down over his crotch, nose pushed against the curly blonde hairs at his base. He rests a moment, trying to keep from coming but it’s hard when he can feel his cock pulse gently against the back of his husband’s throat. The nerd doesn’t even gag, just looks up with those big doe eyes of his, tears gathering in the corners. He whimpers slightly, but doesn’t try to move on his own, knowing that his Kacchan will do what’s best for him.
Katsuki strokes his hair, eyes soft in the fading sunlight. “Good boy… Now tell me, do you want to take my cum now or wait until I’m upstairs and I can fuck into that tight little ass?”
Izuku whimpers again and starts to bob his head. Katsuki can see his arm moving and knows his husband must be jacking himself off with the hand not gripping Katsuki’s thigh and keeping him balanced. Good boy, indeed… Katsuki tightens his grip on his husband’s hair and pushes him down again and again, reveling in the sloppy wet feeling around his dick. Before long, he’s teetering at the brink again, balls pulled up tight against his body. He’s almost reluctant to fall, to lose the sweet sensation of his husband’s sinful mouth, but he knows the night isn’t over. Izuku will wring another orgasm out of him. Besides, his husband is close too. He can hear it in the quiet little moans the nerd is stuttering out, the frantic motion of his hand around his cock. He falls.
“Ah… ‘Zuku, fuck, that mouth is so good. Oh… Oh my God… -- OH MY GOD!” This last is a horrified gasp of surprise and Izuku jumps back, cum spraying across his cheeks and chin. His mouth hangs open, lips swollen and shiny with spit and jizz. He’s panting, cock rock hard and angry against his belly. It jumps a bit, even without touch, and drools a long line of precum down onto the floor. It almost looks like it’s crying. He was so, so close.
“What is it, Kacchan, what’s wrong? Did I hurt you? I didn’t get you with my teeth, did I? You look like you’ve seen a ghost!”
“I… I forgot to pack Mr. Whumpus in Eri’s overnight bag. She’s going to freak!”
“What? That’s what you were worried about, her elephant stuffy? I packed him when I grabbed her pjs.”
“Thank Christ… Fiddlesticks, baby. I’m sorry; I musta scared you.”
“Kaaaaaaaaaaaaaaacchan,” Izuku groans as he sits back on his haunches and wipes his mouth off on his sleeve, “I can’t believe you! I was so close!”
Katsuki doesn’t even have the grace to look ashamed, “In my defense, you look fucking edible like that, so I can’t say I feel too bad about it.”
Izuku puts on his very brattiest of pouts. “Yeah, I’m sure you’re fine with it, Mr. I-Got-To-Cum…”
“Oh, you can jack yourself off, I don’t mind.” Katsuki smirks, scritching his hand through his happy trail. A slow drip of cum pearls on the tip of his still-exposed prick to fall and darken the soft fabric of his joggers.
Izuku blinks slowly at him. “Don’t you think it would be polite to return the favor, darling?” His voice is honey sweet and innocent, which means nothing good for Katsuki.
“Nahhhhhh, I’m good. Feeling pretty tired, honestly.”
Izuku rose to his feet, crowding over Katsuki. “I think we both know that wasn’t really a question, Kacchan.” Izuku’s voice retains its balmy mellow tone, and he smiles gently down at his husband, reaching out a hand to stroke his blond locks.
“And I think we both know that I do what I want,” Katsuki replies, raising his eyebrows. The adult-sized pink ballerina tutu hanging on a hook by the tea set in the playroom begs to differ. It remembers the afternoon Eri wanted to play “ballerina princess tea party” and dragged her Daddy into it despite his vehement protests. But who is the tutu to dispel this man of his delusions.
“I think we both know you’ve learned better by now,” Izuku clenches his fist, using his iron grip on Katsuki’s hair to drag the man to his feet, “So, are you going to act like the good boy I know you are, or do I have to remind you how?”
Katsuki matches his husband’s green eyed gaze, refusing to blink or look away. He sets his jaw, inhales. “Bite me.”
In a flash of green lightning, Katsuki is over Izuku’s shoulder in a fireman’s carry and they’re halfway up the stairs.
“Here’s what’s going to happen,” Izuku instructs, “When I set you down, you’re going straight to the master bathroom and prepping yourself while I get out a few toys. I’m going to remind you what happens when you break the rules, since it’s apparently been too long for you to remember. I put our enema bulb in the back cabinet behind the first aid kit.”
“ That’s where you put the bulb?! I had to go out and buy a whole fucking new one! Shitty Deku, why do you never tell me where you move things to?!”
Finally reaching their bedroom, Izuku is able to deposit his unhappy, squirming charge onto the mattress. He rakes Katsuki over with an appraising eye. “Undress yourself, all the way. I want to see you.” Katsuki obeys huffily, tearing his shirt off over his head and chucking it straight onto the floor in the way he knows Izuku hates.
Izuku just ignores him and begins to pull off his own clothes. “What did you need the bulb for before now, anyway?”
“What did you think I was doing up here for so long when you were downstairs eating dinner with Eri?!” Katsuki averts his gaze, a bright red tinge spreading across his cheeks and even to the tops of his ears, “I wanted to get prep out of the way so we could have as much time as possible to fuck tonight. I made sure I got the bulb and shit ready ahead of time…”
Izuku is stalking closer to the bed now, fully naked, his cock hanging half hard between his legs. He puts his hands on either side of Katsuki’s hips, pinning the smaller man in, “Oh, did you, now? What a smart boy my Kacchan is.” He buries his face into Katsuki’s neck and peppers the skin with gentle kisses. Katsuki shivers beneath him, pressing into the sensation. “Or maybe you’re just a greedy, slutty little thing… So desperate to have a cock in you that you couldn’t wait and do things the way I tell you. Is that closer to the right answer?”
Katsuki whines a little, starting to wiggle out of his husband’s grasp. “Sh-Shut up, you don’t know what you’re talking about…”
Izuku follows him up the mattress. “Oh, don’t worry, baby. I won’t make you say it out loud. We both know you’re not brave enough to admit that all you wanted to do tonight is bounce on me until I make you scream. But I can say it for you.”
Katsuki works his jaw and turns his head away to the side, not willing to look Izuku in the eyes.
“But you know… with the way you’ve been acting tonight, I think you’ll enjoy yourself a little too much. I can’t trust you to keep your hands to yourself and wait to cum until I tell you like a good boy. You know what that means, don’t you?”
Katsuki huffs out another angry breath and puts his arms out behind him.
“That’s right. Good boy.” Izuku leans down, fishing blindly underneath their king sized bed for the unassuming grey plastic container that holds their collection of (long unused) sex toys. He scrabbles around until he can feel faux-leather and soft string and ceremoniously pulls out an armbinder monoglove, black and sleek looking. It looks perfect on Katsuki with the way it makes him present his pecs and arch his back, helping him sit pretty for Izuku.
Katsuki is still waiting for his restraints, looking less patient by the second. “Come on, Deku ! I’m getting bored over here. Fucking touch me already. Christ!”
Izuku makes a show of rolling his eyes and shifting his way back up the bed. Katsuki’s eyes are intent on him, even as the blond fakes a jaw-cracking yawn.
In a flash of movement, Izuku is on him, grabbing him by the hair and shoving his face into the mattress. “Oh, I’m sorry , brat. Is this better?” He grinds his husband’s face into the sheets with one hand, using the other to wrench Katsuki’s arms back into position behind him.
“Yeeeeeeeeeeeess,” is the muffled reply. “Now tie me up and fuck me. I want your dick in my ass like yesterday .”
“Such a brat…” Izuku sighs as he slips the monoglove up Katsuki’s arms, “Keep pushing it and you’re going to get in trouble.”
“You love it,” Katsuki cackles, turning his face to the side so he can peer up at his husband as he tightens the lacing on the armbinder.
“Or something,” Izuku grumbles. He pulls Katsuki back up into a sitting position. “Now, how does it feel? Too tight?”
“Jeeeeeez, it’s fucking fine already. My ass is gonna be the thing that gets too tight if you wait any longer!”
Izuku ignores Katsuki and performs a perfunctory check on the armbinder anyway, slipping his fingers into the glove and pulling to test its give. Katsuki’s right, it’s a perfect fit, but he knows how his husband loves to be forced to wait, to have his complaints and bad manners ignored until Izuku finally snaps and gives him the punishment he deserves, either an ass spanked red and raw or pounding him so hard he nearly passes out and can’t sit for days afterward.
“You’re ready. Now get over here.” Izuku sits up in the bed and pats his thighs. Katsuki, bright red, shuffles across the mattress to straddle his husband’s lap. He glares straight into Izuku’s eyes, as if daring him to say something.
Instead, Izuku curls his hand around the meat of Katsuki’s ass and spreads his cheeks. His finger slowly circles at his husband’s hole, a thrill rushing through him at finding it wet and open.
“Look at you, all ready for me…” he coos as he brings two fingers up to Katsuki’s mouth. “Suck,” he commands.
Katsuki’s brow furrows as he pretends to be offended, but he latches onto Izuku’s long, crooked fingers with fervor, pulling them into his mouth as he looks up through ash blond lashes at his husband.
“That’s perfect, Kacchan. Always so perfect for me…” Slowly, almost reluctantly, Izuku removes his fingers, trailing his hand down Katsuki’s flank and back to his ass. He finds that cute, pink pucker again and slips his middle finger inside.
“What the fuck, Deku?! You saw that I was ready, I sucked your pervert fucking fingers, I did what you wanted! Just put it in me already!”
“No.” The words come with a quiet smile, and a gentle kiss on the nose.
“Come. On.” Each word is punctuated with a backwards thrust of the hips, as Katsuki tries to fuck himself on his husband’s finger.
“Kacchan…” Izuku’s voice is a velvet soft warning. A thrill passes through Katsuki’s body. He knows they’re at a breaking point. Izuku is about to snap at him, to lash out and take him. He just needs to give one last push.
“Come on! Or are you just scared you’re gonna cum in two fucking seconds like when you were a shitty teenager, huh?!”
Smack! Before the words are even all the way past Katsuki’s lips, a smarting heat blossoms across Katsuki’s left asscheek. It’s delicious, but it isn’t nearly enough.
“You can’t fucking handle it anymore, is that it, Deku?!”
Again, the pain flares through Katsuki’s senses. Izuku’s other hand is in his hair again, yanking his head back and exposing his neck. He can feel Izuku’s erection grinding up against his taint and the underside of his balls, insistent. God, he missed this.
Then Izuku is leaning away from him, reaching blindly under the bed again for something else from their toybox. He hopes it’s a paddle. It would be worth the bruises to feel that sweet ache again, the kind of lovely pain that will stay with him for days, in his bones, a constant reminder of tonight.
And yes, there’s Izuku’s hand again, his knuckles dragging up Katsuki’s thigh as he makes his way back towards his husband’s ass. He’s holding something, Katsuki can feel the hard plastic of the handle now and again against his skin. Which is weird, considering that all the paddles they own are faux-leather or wood...
Smack!
“All around the mulberry bush, the monkey chased the weasel! The monkey thought it was all for fun! POP goes the weasel!” The sound of the nursery rhyme comes out tinny and cheap, from somewhere behind Katsuki’s ass.
“Dekuuuuuuuu. Did you just paddle my ass with our daughter’s plastic singing mallet? The one I told you to get rid of two years ago !?”
“N-No… That would be crazy, K-Kacchan. Because you told me to throw it out and I would never save something, planning to donate it and then never get around to it and hide it under our bed for years so you wouldn’t find out and yell at me.”
“Then hit me. Again .”
“Hit you? Nooooo. Kacchan’s being such a g-good boy, he doesn’t need a spanking. Heh heh… heh.”
“ I said hit me, goddammit! ”
“Okay, fine! It is the plastic mallet! I never threw it away; I didn’t want to be wasteful!”
“Deku, I wanted to get rid of that thing because it is the literal spawn of Satan !”
As if to prove Katsuki’s point, the toy begins its rhyme again. It’s lighting up this time too, Katsuki can see the reflection flashing in Izuku’s eyes, purple, red, blue, and green. There is a crunching sound, and the song finally dies off with a deeply distorted “ POP goes the … wea… sel…” Izuku’s arm lifts, his bicep bunching, as he throws it across the room into the trashcan by the door (which is really impressive aim, Katsuki has to admit).
“I… guess you probably want me to go ahead and untie you now, huh?” Izuku asks sheepishly, moving his hands up behind Katsuki’s back to the lacing on the monoglove.
Katsuki lets out an embarrassingly high pitched sound of alarm, “No, don’t!”
“W-Wha? Really, Kacchan? You still want to… Really?!” Izuku’s grin is as bright as the sun when it shoots through the gap in the blinds at the ass crack of dawn, overwhelming and impossible to ignore.
Katsuki averts his gaze and mumbles his next words into his husband’s shoulder, “You just… you feel so good pressed against me like this.”
“Awwww, Kacchan!” Izuku tries to capture Katsuki’s mouth with a kiss.
“I can’t help it, okay?!” Katsuki pulls away, dodging Izuku’s lips expertly, “So don’t you make fun of me like that!”
Izuku can feel himself slipping back into his dom persona as he grabs Katsuki by the jaw, holding his face still. “Embarrassed, love?” He makes Katsuki look him in the eyes to answer the question.
“N-No! It’s not like I even care that much, I--” Katsuki cuts himself with a gasp as Izuku’s fingers once more push into his hole, curling until they press against his prostate. He bucks back against the intrusion, letting his face fall into the crook of Izuku’s neck.
“That’s right… There’s my needy little slut,” Izuku croons, kissing his husband’s shock of blond hair. “Despite all that talk, you’re so easy for me, aren’t you? So ready to just roll over and let me stuff you with my cock.”
Katsuki opens his mouth to deny it, but then Izuku presses a third finger inside him and he can’t do anything but whimper and kiss at the big man’s neck. His prick is rubbing up against Izuku’s well muscled stomach now, and the friction isn’t nearly enough.
“So desperate… Let me hear you beg for it.”
Instead, Katsuki huffs and bites down viciously on Izuku’s shoulder.
Izuku immediately leans away from Katsuki, even going so far as to pull out his fingers. “That’s not how you behave, brat. Apologize.”
“Put your cock in me.”
Izuku grabs one of Katsuki’s nipples and twists it viciously. “Apologize or I tie you to the headboard and leave you there the rest of the night. Alone.”
“You’re lying.”
“You’re right. I’d shove a vibrator in your ass first.”
Katsuki bites his lip to keep from whimpering. “Fuck, Izuku… Please.”
“I said apologize, not beg, love. Come on… I know you can be good for me.”
Katsuki’s dick jumps, and it slaps against his belly, leaving a glossy smear of precome hanging in his happy trail. “‘M sorry, Zuku… I’m sorry, I’ll be a good boy. Just fuck me. I just need you inside me, please .”
Izuku lunges forward to claim Katsuki’s mouth with kisses and slicks himself up with lube from a bottle in the bedside drawer. (It’s deceptively labeled “glasses cleaner,” although the perceptive observer might realize that neither Izuku or Katsuki wear a pair).
Finally, finally Katsuki can feel the blunt head of his husband’s cock against his asshole and bears down. He whines as Izuku slips in, pushing ever so slowly until he bottoms out. There is a moment of stillness then, as Izuku allows Katsuki to adjust to the sensation of being so completely stuffed full.
Katsuki isn’t having any of it, rocking forward and back on his knees, trying desperately to fuck himself on Izuku’s cock without the use of his hands.
“Please, Zuku! I need it, I need you, just hurry up and fuck me already! Please! ”
“Well, since you begged so prettily…” Izuku plants his feet on the mattress and leans back, one hand coming out behind him for balance while the other snakes around Katsuki’s back and under the monoglove to grip his shoulder, so that Katsuki’s weight rests in the crook of his elbow as he fucks him like a fleshlight.
With his arms bound like this, there isn’t much Katsuki can do except try to stay upright and speared on his husband’s cock. Izuku laughs when he notices Katsuki’s abs trembling with the effort, the flex in his thighs as he tries to counteract the force of Izuku’s hips pounding into him.
“Look at you, such a helpless little cocksleeve. Poor Kacchan… Can’t even touch your own cute little dick like this, can you, precious?”
“Fuck you! I can do whatever I want!” Katsuki lunges forward, trying to press his cock against Izuku’s stomach, to kiss his husband’s smirking lips, or savage hickeys into his neck. Anything to show he isn’t just a powerless little toy. He’ll show Izuku! He’s strong, he’s in charge, he’s--
He’s being shoved backwards, Izuku’s massive hand in the center of his chest, shifting his center of gravity until he topples, helpless, into the mattress, his arms trapped under his body and a cock still shoved in his ass. Izuku towers over him, that bright shining smile on his face even as he grabs Katsuki’s thighs and pushes them up around his ears so he can fuck even deeper into Katsuki’s ass.
The angle is perfect, hitting Katsuki’s prostate every time, and Katsuki squirms, trying to get Izuku to fuck him harder, faster, more. But he can’t move, he’s completely trapped under his husband’s weight. No matter how amazing this feels (Izuku pressing down on him, deep inside him, letting Katsuki’s cock grind up against those rippling abs) Katsuki can’t stay like this any longer. His shoulders and arms hurt pinned under him, like someone’s started poking electric needles into his nerve endings.
“Fuck, baby, ‘Zuku, yellow.”
Immediately, Izuku is pulling back, a look of worry on his face, “What’s wrong?”
“Arms. Flip me.”
“Want the glove off?”
“Noooo, please no.” Katsuki couldn’t stand that. He needs the glove, how it keeps him contained, a good boy like Izuku wants. He loves the stretch it puts into his shoulders, how it puts him on display.
“Shh, it’s okay, it’s staying, I promise.” Izuku gently turns Katsuki over on the bed. He runs his hands over the monoglove, smoothing out the creases and wrinkles so it’s sitting right on Katsuki again. His hands keep going, petting down Katsuki’s ass and his legs, gentling the twitching muscles.
Katsuki pops up onto his knees, his chest still pressed into the mattress, and any discomfort already forgotten. “Alright, Deku, your break time’s over. Get back over here, lazy bastard.”
Izuku rolls his eyes and plays along, “Mmm, yup. I was just so tired, you know, Kacchan’s ass is too amazing. If I hadn’t stopped I would’ve cum.”
“Damn right it is! Now put it back in me!” Katsuki wiggles his rear teasingly. It makes his cock sway, slapping against his thighs as it hangs there, half hard after the lack of attention.
Izuku ignores him, instead leaning in to lap a wet stripe up his balls and taint. Katsuki squeals, a rare sound from him, and one he tries to hide with a (not very convincing) growl.
“What do you think you’re doing, Deku?!”
“Whatever I want… you’re my good boy after all, aren’t you? My toy?”
Katsuki groans and buries his face deeper into the sheets, but he doesn’t deny it. He can’t when he knows, deep down in his bones, that Izuku is right . He is just his Zuku’s little toy, to play with in whatever way he chooses. But he doesn’t want to be anything else.
Katsuki is slowly getting harder as Izuku suckles wet kisses into the backs of his thighs. He’s going to have hickeys there after this, and he knows from experience that at night when he shucks off his boxers to climb into bed, Izuku will seek them out again with his mouth, making the marks last for months, if he can. (If Eri stays asleep in her own bed, in other words).
Finally, when Katsuki’s trembling and muffling his moans into the mattress, Izuku presses his cockhead back against his husband’s hole. He’s slicked himself up again, and when he thrusts inside, it’s a smooth glide all the way to the base. Katsuki can feel the warm press of Izuku’s balls against his taint and he wriggles his hips to feel them slide against him.
Izuku slaps him against his left ass cheek, a playful warning. (Katsuki can tell that his husband’s avoiding his right side where he was hit with the mallet. There’s definitely going to be a bruise there. Sitting down to drive Eri to school tomorrow is going to be so much fun!)
“Hold still for me, Kacchan, like a good boy.”
Katsuki, of course, wriggles even harder. Heat flares in his belly when Izuku grabs his hips with one hand and his hair with the other, “I said hold still, baby.”
Katsuki relents and keeps still for Izuku. The big man chuckles, “Good boy… Now hold on. I think it’s time I pay you back for not letting me cum earlier.”
The hand in Katsuki’s hair becomes an anchor, holding him in place as Izuku starts to jackhammer into him. Izuku lets out a long, low groan of relief, and his pace somehow picks up even more.
“God, you feel so good around me, Kacchan… So perfect, so tight. I missed your ass so much. I’ve been dreaming about it, baby; you know you’re all I can think about sometimes. Having you under me like this all desperate… Or even tying me up and riding me. I wouldn’t care. I just want you any way I can get you. No matter what you give me, it’s always perfect. You’re so perfect for me, Kacchan. Ahhh… I love you so much.”
If Katsuki was coherent enough to pay attention to his nerd’s rambling, it would melt his heart like it always does to hear how much Izuku cares for him, how unconditional his love is. But at this point, Izuku’s back to nailing Katsuki in the prostate on every thrust, and all he can think about is the heat of Izuku’s palms on his hip and in his hair. They’re his only points of contact to the real world anymore; the rest of his consciousness is lost to the thumping rhythm of the headboard hitting the wall and the soft, effusive pleasure of being Izuku’s lovely little cocksleeve.
He doesn’t realize at first how much he needs to cum, until he hears the whiny moans suddenly escaping his own mouth, and Izuku’s soft coo of a response. Then that big, scarred hand is wrapped around his length, jacking him once, twice and he feels his whole body tighten, then release.
Like every time he cums from his prostate, the orgasm rolls through him in seemingly endless waves. It’s a steady pulse radiating through his body, tingling down into his toes and up into his scalp. Izuku keeps grinding into him through it all, coaxing crest after crest of pleasure out of his shaking body. When it becomes too much, he clenches up, tries to shake Izuku’s hand away from his cock.
His green haired husband gasps in surprise, and that final squeeze is enough to send him over the edge himself, pressing his pelvis against Katsuki as he spills deep inside him. Katsuki loves the way the sticky warmth blooms inside his belly, filling him to the brim. He sighs and crumples against the bed. He keeps his face tucked against the sheets, the dark press soothing against his exhausted eyes. He honestly could go straight to sleep… Especially after Izuku has unlaced the monoglove and Katsuki’s arms can finally slip down against his sides. They tingle, like they always do after being restrained for so long. It’s as satisfying as the pull of his muscles after a long session at the gym or the ache in his balls after a particularly intense orgasm.
At some point, Katsuki feels the mattress dip as Izuku rejoins him on the bed. Then, there’s the press of a cool, wet washcloth against his hole as Izuku tries to clean up the sloppy mess. Katsuki grumbles and tries to pull away from the jarring sensation, but he’s too tired to even sling a “shitty Deku!” his husband’s way.
He can hear Izuku laugh and then feels the gentle warmth of Izuku’s lips against his neck, “Hold still, wiggle worm. I have to clean you up. I know you don’t want dry cum stuck to your ass hair, or don’t you remember how much that hurts?”
Katsuki relents, spreading his legs for Izuku’s softly probing fingers. It even starts to feel nice, after he gets used to the cold. Of course, that’s when Katsuki’s phone rings from the bedside table. He groans loudly and covers his ears with his hands.
“Zukuuuuuuuu, you get that! Don’t want to moooooooove.”
Izuku fights down a laugh and picks up the phone as he is bid. “This is Bakugou’s phone. … Oh, hi Amajiki-san. Is everything going okay with the sleepover? … A nightmare? Oh, poor baby…”
Katsuki sits bolt upright and yanks the phone out of Izuku’s hand. “Eri had a nightmare?! Is she okay?”
Amajiki’s quiet voice filters in from the other end of the line, “Oh, Bakugou, there you are. Yes, Eri came downstairs about ten minutes ago to tell us she had a bad dream and couldn’t go back to sleep. Mirio tried to talk her through it right away, of course, but she’s still upset. He asked if she wanted us to call her Daddy and Papa, and… well, here we are.”
“Put her on right this minute.” Katsuki is holding back a snarl, one fist clenched in his lap. Eri’s first sleepover, and this is what happens?! Couldn’t the poor girl catch a break? What if she never wanted to sleep away from home again after this? What if--
Izuku’s hand closes over Katsuki’s, he lets himself take a deep breath and then Eri’s voice fills his ear. Katsuki puts the phone on speaker immediately.
“Daddy? Papa?”
“Yes, Eri-bee, we’re here.” Izuku squeezes Katsuki’s hand again, and it’s clear he’s trying to keep himself from tearing up.
“I had a bad dream… I dreamed that Kota and I were exploring the jungle but I fell into quicksand and I couldn’t get out! And then… And then when I fell down into it, there were sand monsters and they tried to hurt me.”
“Eri, baby… It’s okay. It wasn’t real, I promise. You know your Daddy would never lie to you, right?” When Katsuki talks to Eri, his gruff voice mellows out into a rumbling sound, like the motorboat purr of an old tomcat.
“I know. Even when Papa thinks you probably should.”
“H-Hey!” Izuku squeaks, “I told you that in private, Eri! Don’t you tell on me!”
The sound of Eri’s tiny giggle fills the air and Izuku and Katsuki both let out a huge sigh of relief.
“Do you want me to come pick you up, Eri-bee?” Katsuki asks, worry still clinging to his words.
“No… I’ll be okay. I think I can go back to sleep now. I just wanted to tell you about it. And say that I love you.”
“We love you too, sweetheart,” Izuku chimes in, tucking his chin over Katsuki’s shoulder and planting a kiss on the bare skin. “We miss you sooooo much, and we can’t wait to see you tomorrow.”
“Why do you miss me, Papa? I’ve only been gone a night, you silly!”
Katsuki cackles out a laugh while Izuku is stuck with his mouth hanging open, looking like his whole world just got torn apart, “You got him there, Bee! Good one. We’re gonna let you go back to bed now, okay? Mirio will tuck you in.”
Izuku has apparently rebooted because he chimes in with, “Give Mr. Whumpus a kiss for us! Sweet dreams!”
“Sweet dreams, Papa. Good night, Daddy.” Eri then hangs up the phone to a chorus of “goodbyes” and “we love you”s from her fathers.
When the line goes dead, Izuku and Katsuki collapse against each other, breathing a mutual sigh of relief.
“Okay, don’t judge me for this, but I am actually so glad she didn’t want to come home…” Katsuki admits into his husband’s collarbone, “My ass hurts so bad, I didn’t want to sit on it for the entire 30 minute car ride there and back.”
Izuku winces sympathetically and pats Katsuki on the back, “Should I get you an ice pack, or…?”
“Nah, I’ll be fine. I’ll just sleep on my stomach tonight. And possibly for the rest of the week. And you’ll be driving Eri to school every morning next week so I can walk to work instead.”
“That is completely fair, and I will do so gladly.” Izuku replies with a conciliatory kiss on his husband’s cheek. He flops onto the mattress and raises his arm up, beckoning Katsuki in for a snuggle, letting the blond use Izuku’s massive pec like a particularly warm and nipply pillow.
“By the way, Kacchan… Don’t feel too bad about not wanting to pick Eri up early. I am so looking forward to sleeping naked tonight, I’ve been dreaming about it for weeks. And besides… This just shows how independent our little girl’s become. I’m so proud of her.”
“Me too… God, I love her so much! I can’t fudging stand it! Just as much as I love you, nerd.”
“Aww, Kacchan! I love you too!”
“Why are you acting so surprised that I said I love you! I just let you tie me up and pound me in the ass!”
“... And we’ve been married for seven years?”
“Yeah, and that too! Jeez, stupid Deku. Can’t believe I love such a massive dork…”
“That’s my Katsuki…”
“And don’t you forget it!”
