Work Text:
“Kacchan?” Izuku croaks, voice hoarse and dry from their earlier activity. He looks over with hazy eyes, trying to get a glimpse of the blonde in question.
Katsuki hums, rubbing Izuku’s back while simultaneously reaching for the water bottle on top of the nightstand. He removes the cap and places it against Izuku’s parted lips. “Drink, you’re just coming down from subspace.”
Izuku takes the bottle and drinks it, giving Katsuki a grateful look. The cold water soothes his aching throat, having been screaming for the past hour during their scene. Katsuki has always been a good Dom, no matter how soft or rough he gets. He also always makes sure he is taken care of afterwards, even when Izuku is completely out of it, so phased out in subspace but trusting Katsuki during his stage of vulnerability. He cleans him up, bathes him, and soothes his aches as he comes down from the height of pure ecstasy.
Izuku hands him the water bottle upon quenching his thirst and lies on top of Katsuki’s chest. The ointment around his wrists from the leather bindings glisten under the bedroom light as he slowly brings his hand up to his eye level. He traces each dip and curve of Katsuki’s well built chest with his fingers, eyeing his pecs and giving one a gentle squeeze.
Katsuki grumbles as he brushes his hand away, earning a chuckle from Izuku. “Do not start up again. I’m still sore.”
Izuku snorts. “Really, Kacchan? I didn’t see you tied up with rope and hoisted into the air.”
“You’re really gonna start shit? Try actually lifting the person into the harness.”
“You spanked me really hard, your quirk made burn marks on my ass.”
“Heh, can’t argue with that. Though I still had to find a good angle when I fucked you good to make you scream.”
“A scream that was muffled by a ball gag, Kacchan.”
“A scream’s a fucking scream, nerd. You’re the one into this kinky shit.”
“So are you!” Izuku lifts his head up to meet Katsuki’s carmine gaze. He juts his lips out into a pout upon seeing his boyfriend’s grin. “You said that’s what you like to do when you’re the Dom!”
Katsuki scoffs, rolling his eyes. “I’m always the Dom. You just really like to be dominated, you sexy little minx.”
He emphasizes his point by reaching down to lightly squeeze Izuku’s bare ass cheeks, slathered in burn treatment from the accidental quirk use. This earns a small squeak from Izuku, causing Katsuki to laugh at his expense. Izuku’s pout is more prominent at this.
“You’re mean, Kacchan,” Izuku says, but he curls up some more into Katsuki’s warm embrace. Katsuki always radiates heat, which helps with the aftercare. Whether it’s because of his quirk or if this is just a Katsuki thing, Izuku doesn’t know, but he likes the warmth nonetheless.
He feels Katsuki place a kiss on top of his head, his green curls still damp from the much needed bath. The arm wrapped around him tightens and rubs his arm up and down in an act to comfort him. It helps, but Izuku’s mind still whirls around with his thoughts, which is usually silenced upon reaching subspace. Now that he is out of it and his brain finally caught up to current events, he can’t help but wonder…
As if sensing his turmoil, Katsuki hums and pulls him further into their embrace. “What’s going on in that pretty head of yours, nerd?”
Izuku takes a deep breath, drinking in the musk that is Katsuki Bakugou. “Nothing, ‘m just tired…”
He can feel the scrutinizing look, and Izuku has to wonder if he’s going to push it. However, it seems that luck is on his side for now as Katsuki sighs deeply, placing his chin on top of Izuku’s head.
“Whatever, ‘m tired, too. Gotta get some shut eye for work tomorrow, anyway,” Katsuki grumbles out, taking one of his hands and carding his fingers into Izuku’s hair.
Izuku hums at the contact, breaking his train of thought for just a moment. He closes his eyes as he realizes that sleep sounds amazing right now. He feels Katsuki’s breath evening out and soft snores can be heard from above him moments later.
Izuku will get a chance to talk to Katsuki, but for now, he drifts to sleep, ready for another day of hero work.
Katsuki can tell the nerd is off.
It’s been a few days since their scene, and now Izuku is skittish around him, as if he’s afraid of him. When they’re on patrol together, he’s the usual nerdy self, but otherwise, he keeps things professional and hasn’t been at his place for another scene since.
What the fuck?
Did something happen? Did he overstep with something with their last scene? Izuku seemed really into it and never signaled that he was uncomfortable with something he did, so he didn’t bother stopping. They always communicate with each other about this type of shit. They’ve gotten a lot better at it since the war. So imagine his shock when Izuku is trying to hide, shying away from even confronting Katsuki.
It was during one of their patrols and there was a big lull between each other's shifts that Katsuki finally found the courage to bring it up. They were both in the locker rooms alone together as Izuku was finishing up the morning while Katsuki had just started his patrol. He was lacing up his new red shoes (thank God, Katsuki was about ready to throw out the old pair) when he stands and bids his farewell.
“Whelp, see you later, Kacchan!” Izuku says a little too cheerfully as he briskly makes it for the exit.
His hand reaches out and grabs that damn cape before he could escape. Izuku squeals in surprise as he is pulled back into the room and his back is slammed against the lockers. Katsuki places his hands between the nerd, effectively locking him in place so he cannot escape. Izuku looks up at him, eyes wide like saucers, as Katsuki leans over him, eyes glaring daggers into his soul that makes him shiver under him.
“Uhh… K-Kacchan?” Izuku stutters out, a bead of sweat dropping from his forehead.
“Tell me what I did wrong,” Katsuki says point blank.
Izuku blinks, a confused look on his face. “Wh-What?”
“You’ve been avoiding me all week!” Katsuki accuses, gabbing his finger into Izuku’s chest, making him wince. “What did I do wrong? Did I make you uncomfortable during our last scene? Did I accidentally ignore a safe word you may have said and I just didn’t hear it? Just fucking talk to me, I’m your damn boyfriend, for fuck sakes!”
Izuku bristles at the fact, “Kacchan! I-I’m sorry that I made you feel that way, b-but really, you did nothing wrong during our scene together!”
“Then what’s wrong? Why are you suddenly so skittish around me?” Katsuki asks, definitely not starting to tear up as his thoughts go down the rabbit hole of conclusions he logically knows cannot be true.
“R-Really, it’s not you, I promise!” Izuku says, waving his hands in front of him. “I-It’s more of a me problem, okay?”
Katsuki gives him a look, anticipating the answer right away. Izuku squirms under him, and his breath hitches when he doesn’t give his answer immediately. Izuku seems to sense this as he stammers out something coherent.
“K-Kacchan, l-look, let’s just w-wait until you’re done with work, okay? Th-This isn’t the right time to d-discuss this sort of thing—”
“No,” Katsuki says firmly, hating the way his voice starts to shake. Izuku freezes in his spot, flinching slightly at the tone. “If you don’t tell me what’s going on right now, I’m gonna think the fucking worst! We’ve been getting better at communication, and I don’t want it going down the damn toilet if you cannot be honest with me—”
“I WANNA TRY TO BE THE DOM THIS TIME, OKAY?”
Katsuki stares at the trembling form of his boyfriend, face scrunched up and flaming red from sheer embarrassment. He covers his face with his hands, attempting to make himself small as he slowly slides down. Katsuki has some sense to pick Izuku back up onto his feet and peel his hands away from his face.
“Oi, look at me,” Katsuki says, and Izuku peeks up at him, eyes filled with worry, as if he is overstepping a boundary. Katsuki rolls his eyes as he lifts his chin up to have him look directly in his eyes. Izuku blinks, his worried look still written all over him.
“Care to repeat that?” Katsuki asks, “and this time, look at me when you say it.”
Izuku gulps, his Adam’s apple bobbing against his neck. “I-I w-wanna be the Dom n-next time…”
Katsuki’s face flushes warm, but he tries not to show it as he lets go of Izuku’s chin, backing away from the lockers in order to give Izuku some room to breathe. “So, why avoid talking to me? Why the secrecy and shit?”
Izuku grabs the hem of his shirt and fidgets with it, eyes casting down onto the floor. “W-Well, I… I didn’t want to say anything b-because I didn’t know how y-you would feel about the whole thing… Don’t get me wrong! I-I like it when y-you’re the Dom, b-but I wanted to t-try it myself. B-But if you’re not comfortable about it, I-I understand…”
Katsuki scoffs. “You think I can’t handle being a damn Sub? Don’t you remember what I said when we first started?”
Izuku’s hands fidget even harder on his shirt. “Th-That you didn’t care who Doms and who Subs…”
“And?” Katsuki says, waving his hand in the air.
Izuku groans. “Th-That you d-don’t do shit that you don’t w-wanna do…”
Katsuki grins at that. “So what’s the big deal? If you wanna Dom next time, we can fucking do that.”
Izuku perks up at that, eyes wide. “R-Really?”
“Yep,” Katsuki says, popping the ‘p’ for emphasis as he starts to head out of the locker room. “We can discuss likes and dislikes after my shift, got it?”
Izuku nods his head, a small smile on his face. “O-Okay… B-But just so you know…”
Katsuki raises an eyebrow, pausing right in front of the door as he turns back to Izuku.
Izuku appears nervous, but he looks directly at Katsuki and finishes his train of thought. “You might be surprised by what I want to do…”
Katsuki rolls his eyes, smirking at him. “Try me, nerd.”
Katsuki sits at the kitchen table and stares at the list that Izuku made while on his break. He stares at it for a good, long minute before he puts it down onto the table and looks up at the already sweating boyfriend of his, shaking like a leaf.
“Shit,” Katsuki breathes out, “you’ve been holding back on me with these.”
Izuku taps the table as his eyes shift to the side. “W-We don’t have to do everything, you know. Just… Wh-What you’re comfortable with.”
“Isn’t that why we’re here?” Katsuki asks, raising an eyebrow.
Izuku doesn’t respond and instead hums deeply, sinking into his chair slightly.
Katsuki sighs, “would it make you more comfortable if we start with the hard passes?”
Izuku perks up at that, nodding his head silently as he folds his hands on the table. Katsuki can’t help but chuckle at the reaction as he reaches for a pen in his pocket. He clicks it once and goes to cross out a few things on the list already that we’re a definite no for him.
“First off,” Katsuki says, making sure they have verbal communication on their do’s and don'ts, “anything to do with piss or shit is off the fucking table. I don’t do it to you, and it’s fucking gross. So don’t even think about it.”
“Got it,” Izuku says, face flushing red from the prospect.
“Secondly, no blood play, that is just diseases waiting to fucking happen.”
“Okay.”
“Age play, age regression or anything in that category is a hard pass. Like hell I’m gonna act like a damn baby and you know I hate it when someone coddles me.”
“Mhm, got it.”
“I’m not into any of this hardcore role playing, so I’m crossing that out.”
“Right.”
“What the fuck—Cock cages? Hot wax play? Do I look like the type of guy that’s into that shit?”
Izuku fumbles at that question, his fingers curling inward. Katsuki feels his eyes twitch from the lack of response as he dramatically crosses the suggestions out.
“No,” Katsuki says with finality.
“Okay, Kacchan.”
“Now then,” Katsuki says as he looks at the rest of the list that Izuku concocted. The rest of the list contains activities that Katsuki has yet to explore with Izuku, but is genuinely curious with the ideas.
“So, the rest aren’t a definite no,” Katsuki says, looking up to see Izuku’s eyes light up. “But, some need some adjusting for my comfortability. Got it?”
Izuku nods his head, his hair flopping around on his head that in any other situation, Katsuki would find it comical. He then goes to make the necessary addendums to the remainder of the list, scrawling the words out with ease. He clicks the pen closed and slides the paper back to Izuku so he can take a look at it.
Izuku picks up the list and scans it with his own eyes as Katsuki explains his compromises.
“I’m not a fan of pet play, it’s similar to age play to me. But, if you’d like, you can put a leash and a collar on me and use the phrase ‘good boy,’” Katsuki says, using air quotes, “otherwise, treating me like an animal is off limits.”
“Okay,” Izuku says, eyes still on the paper.
“I don’t fucking care what you call my damn parts, but stick with the terminology. You wanna call my asshole a cunt? Go ahead. Wanna keep calling my dick a dick? Fine.”
Izuku nods his head in response.
“We’ll obviously still use our color system, since it works, but for fuck sakes, don’t ask every five seconds for my color. That will ruin the damn scene.”
“You don’t usually ask me a lot.”
“Exactly. It’s a mood killer,” Katsuki says with a sly grin. “It still gets you going.”
“I… I guess…” Izuku says, putting the paper down onto the table. “But what about the lingerie? You didn’t cross that one out.”
Katsuki raises an eyebrow. “I’m gonna let you figure that one out.”
Izuku stammers, eyes wide and face flushed red, but looking closely, it is not from embarrassment. Katsuki can see clearly that he is thrilled, judging by the spark in his eyes.
“Y-You want to wear lingerie?” Izuku stutters out.
“Heh,” Katsuki says, smirking at him, “I’ll even let you go shopping for that one.”
Katsuki can hear Izuku’s foot rapidly tapping on the floor, as if he’s trying to contain his excitement. Pride swells in his chest for getting his boyfriend in such a state that if he had a tail, it would most surely be wagging.
Katsuki almost reconsidered the full pet play for when he’s Dom.
Almost.
“Okay, Kacchan!” Izuku says a bit too excitedly, scanning the paper once more. “And it looks like you’re okay with edging and having multiple orgasms?”
Katsuki snorts. “Mainly because I wanna see you try to get me off more than once.”
Izuku gives him an incredulous look. “Are… Are you insinuating that I can’t get you off?”
“Oh, I know you can get me off,” Katsuki says, crossing his arms, “but I think it’s only gonna be once. Maybe twice if you’re lucky.”
Izuku bristles. “I can get you off more than that!”
“Really? Is that a challenge?” Katsuki asks, his smirk widening.
Izuku stares at him, as if contemplating it. It takes him a minute before he narrows his eyes. “Yeah, yeah it most definitely is.”
Katsuki leans back into his chair, eyeing his boyfriend up. “Alright, how about a bet then, if you cannot get me off more than three times during the entire scene, you’re gonna sit your ass down on my cock and watch a movie of my choosing.”
Izuku breathes through his nose loudly, his nails digging into the wood of the table. “Not ‘The Thing,’” he whispers.
Katsuki simply nods his head. “Yep, and this time, you’re gonna sit through the entire dog scene without screaming at me to turn the damn TV off, ya hear me?”
Izuku starts to tremble, and Katsuki simply watches with glee as memories of their last movie night a few weeks ago replays in his mind. It was Katsuki’s turn to pick the movie, and when that specific scene came on, Izuku was a weeping mess that they had to stop the movie. Even though Katsuki had reassured him that they were simple puppets and animatronics and no real dogs were harmed, Izuku still refused to watch the rest.
It took him a few days to get over it and pet every dog he saw while on patrol, so Katsuki thinks it’ll be a perfect opportunity to try again.
Hopefully the cockwarming would sweeten the deal, since he’s into that shit.
Izuku takes a few deep breaths as silence passes the two for a brief moment. Katsuki taps his finger against his arm, waiting for Izuku to respond as his patience wears thin. Eventually, Izuku stares at him and gives him a small smile.
“Alright,” Izuku says, “but if I do get you off more than three times, you’re going to accompany me to the next Pro Hero Gala.”
Katsuki raises an eyebrow. “What’s the catch?”
Izuku’s smile widens. “You get to wear a dress instead.”
What the fuck.
“HAH?” Katsuki shouts, standing up from his chair that it screeches on the floor. “What the fuck? You’re taking advantage of the fact that I’m okay with lingerie, nerd!”
Izuku gives him a tooth-rotting grin. “So it’s a deal? If you win, I will watch the movie, and if I win, you will wear a dress to the Gala!”
Katsuki grits his teeth as he glares daggers at his boyfriend. He’s not completely against the idea of wearing a dress, per se, he doesn’t care one way or the other. He knows he could pull it off, since he’s got the damn body to prove it. It was the insinuation that he would have to wear one because Izuku won the bet between them.
And Katsuki will be damned if he lost this particular bet.
Katsuki slowly sinks back down into the chair, taking two deep breaths in order to calm himself down. He then smiles back at Izuku before he answers.
“Sure, we have a deal,” Katsuki says.
Izuku’s smile widens. “Okay!” He then grabs the paper and folds it back up to put in his pocket. “I’ll go order us some food, then.”
Katsuki nods his head as they both walk away from the table and head toward the kitchen. Izuku calls for take out while Katsuki looks around in the fridge for something to drink. He settles for a mango flavored soda and goes to drink it, all the while letting the discussion settle into his system.
He won’t lie, this will be his first time being the Sub, so he is a bit nervous. Still, when the two first started, he told Izuku point blank that he didn’t care what role he played, as long as the two of them were alright about it and consented. Izuku admitted to being more comfortable being the Sub due to his nerves about the whole thing and Katsuki respected that.
That was two years ago.
Why the sudden change of heart? Sure, people are allowed to change their minds and after some time they get comfortable with the thought. Still, after two years of Katsuki being strictly Dom and Izuku being strictly Sub, there’s a learning curve to this whole thing.
And if Izuku starts to get uncomfortable during the scene? Then it’s fine, they can go back to their normal routine and call it a day. They have tried something different, it didn’t work, they go back to normal and everything’s okay.
Katsuki drinks his soda, staring into a random corner of the kitchen, unaware of a pair of arms wrapping around his waist from behind. When it finally registers the moment a head is placed in the crook of his shoulder, he turns and kisses the top of Izuku’s unruly green curls.
“Dinner will be here in twenty minutes,” Izuku says. “I also know exactly what to get you for our scene, so give me a few days, okay?”
Katsuki rolls his eyes. “Alright. Whenever you’re ready, let me know and we’ll set a date.”
Izuku nods his head, burying his face into the shoulder blade. They stay like this for a brief moment before Izuku perks up slightly. “Oh, one more thing to add if it’s alright?”
Katsuki hums as a response before taking another swig of his soda.
“Can you call me daddy?”
Katsuki almost chokes.
Katsuki stares at his reflection, face flushed red, while Izuku is preparing in the bedroom. He turns his body side to side in order to see the lingerie all over.
Izuku wasn’t kidding when he said he was going to get something specific. Here he was wearing the latest ‘Deku’ themed design for his lingerie line. It’s a dark green babydoll design with laces and frills all over, along with some bunny silhouettes all over the sash that lies underneath his pecs. The tiny thong he wears leaves nothing to the imagination, his cock struggling to stay in, even though it’s not fully hard right now.
Shit, they haven’t even started and he’s already about to bust a nut.
“Kacchan?” Izuku says through the door, sounding nervous as all hell. “Everything okay?”
Katsuki takes a deep breath and shakes his entire body, getting rid of all of his nerves from his body (it’s not physically possible, but it’s the thought that counts). He turns to the door and shouts from where he’s standing. “Yeah, I’m good. Just give me a minute.”
He can hear Izuku hum and a shuffling of feet retreating from the door. Katsuki knows he’s getting himself ready for the scene, so he takes one last look in the mirror, making sure everything’s in order, before he walks over to the bathroom door that separates him from the bedroom where Izuku is waiting for him.
Katsuki reaches the door and pauses. He knows exactly what is going to happen the moment he makes the signal, so he gives his body an inner scolding to not violently react, lest he burn the place down.
Katsuki knocks on the door twice before opening it slowly.
A crooked hand immediately grabs him by the arm and pulls him against a bare chest, causing him to gasp loudly. Another hand wraps around his waist, bringing the lacy fabric up slightly to expose his stomach to the cool bedroom air. A breath ghosts over his neck and a warm tongue licks on the most sensitive spot there, causing Katsuki’s breath to hitch.
Izuku hums from behind as his grip tightens. “Look who showed up looking so delectable. Such a pretty thing, it’s a shame I’m gonna get it all nice and dirty.”
“Wh-What?” Katsuki asks, unable to help himself and cursing at how winded he sounds right now.
Before he could think, he is immediately pushed onto the bed, his face hitting the soft sheets below him. The hand that grabbed his arm holds it tight above him as the other one fumbles around to grab something he can’t see. Yet, the moment he hears the jingling of the chain, he knows exactly what Izuku is getting.
Izuku chuckles above him as he feels something soft wrap around his neck. “Don’t worry, I’m not gonna hurt you. This is just a reminder of who’s in charge here.”
Katsuki shivers at the sound of his voice, all deep and dark and yet still soft. It stirs something in him that he doesn’t register the clasp of the collar snapping in place, officially around his neck nice and taut.
Katsuki earlier completely forgot about the whole collar thing, so he snagged an unlicensed Dynamight themed collar and leash from his dresser drawer that he found at a third-party sex store (he still, to this day, has no idea what possessed him to get it that day, only for him to thank any deity from above that he had it for this occasion). It was fully black with an orange stripe in the middle and an X immediately under the chin. The chain to the leash attaches from behind on a hook with the back leather strap at the end for the user to wrap their hand around.
And in this case, Izuku uses it to his advantage as he tugs at it, making sure it is secure around Katsuki’s neck.
“Good boy,” Izuku says, his voice dripping with pride as Katsuki can feel Izuku’s hard member rubbing against his ass cheeks. He feels a hand grab ahold of one and kneads it firmly and a low moan is heard from above.
“Fuck, you’re so gorgeous, baby,” Izuku swears, and that alone makes Katsuki’s cock twitch in the panties.
Very rarely does Izuku curse, and when he does, it’s like a Pavlovian effect that either makes Katsuki pounce on him or has to make a detour to the damn bathroom before anyone sees how much it affects him. Turns out, Izuku picked up on that, and is using this to his advantage.
“You dress up so nicely, wearing my colors like this. You were just begging for it, weren’t you?” Izuku says, tugging at the leash and leaning forward so his breath can be felt against Katsuki’s ear. “I can’t wait to make you beg for my cock and stuff your cunt full.”
Oh. Oh shit.
How the fuck.
Katsuki doesn’t get a chance to comprehend how Izuku is able to get him so hot and bothered by his words when he feels a hand slap his ass hard, causing him to gasp. He can feel that cheeky grin against his ear when the same spot is spanked again.
“Ah!” Katsuki shrieks, his head thrown back as he digs his hands into the sheets below him. “D-Daddy!”
Izuku hums as he rubs the cheek. Katsuki feels Izuku latch onto the crook of his neck with his mouth as he sucks on it. It distracts him long enough for another smack to come down, harder this time.
Katsuki winces, earning a chuckle from behind. Izuku then leans back, as if admiring his work, a low moan permeating the room. Goosebumps cover Katsuki’s entire body, sending his mind down a spiral of several emotions at once, his cock getting harder and trapped in the slim fabric.
“What’s wrong?” Izuku asks playfully, his finger hooked against the string between Katsuki’s cheeks and tugging it up and constricting his cock even more. “You look like you’re about to burst and I barely did anything. That’s a shame, I really wanted to take my time with you.”
Any other day, Katsuki would toss a retort at the audacity of this man. However, they’re still in scene, and he really wants to get off, so he plays it up a bit as he turns his head and gives Izuku his best pleading look.
“I can take it, daddy!” Katsuki says breathlessly. “P-Please!”
Izuku gives him a look, and Katsuki realizes that this is the first time he’s seeing him while he’s Dom, his eyes widening at him. Izuku doesn’t look like his normal blubbering mess or appears to be worried about anything. He looks confident, daring, and a sense of dominance protrudes through his gaze as he looks down on him.
Katsuki has seen Izuku at his best and at his worst, especially when he works as a Pro Hero. He is calculating, clever, and knows when to change tactics on the fly. He also throws himself into situations where he would get himself hurt. His self-sacrificing tendencies have dwindled throughout the years, thanks to Katsuki being on top of him, but it still happens from time to time.
This version of Izuku, the one who dominates the bedroom with his deep, sultry voice, is whole new territory for him that Katsuki is not sure if he really likes.
His dick begs to differ.
Izuku raises an eyebrow as his hand gently caresses Katsuki’s ass, still stinging from the spanking from earlier. “I’ll hold you to that. Now lift your hips up for me.”
Katsuki hesitates slightly, but once Izuku tugs at the leash, he immediately obeys. He turns his head forward once more and slowly lifts his hips up into a slight angle, his ass now on full display for Izuku to enjoy. The leash is released and he feels both hands now grabbing onto each of his ass cheeks, kneading the flesh as Izuku humps his clothed cock against him.
Katsuki feels the thong being pulled away to the side as his cheeks spread wide, revealing his hole, small, tight, and only rarely touched. Katsuki had only ever fingered himself a few times to get himself off on days he needed it the most. He hasn’t done it in a while, and he anticipated this to be a possibility for tonight. Katsuki debated whether or not to prepare, but he decided against it, trusting Izuku to be gentle and careful with him, even during the scene.
“Good boy,” Izuku says, and Katsuki doesn’t get a chance to react to the praise when he feels something wet against his taint and slowly straight to his hole. His grip on the sheets tightens as Izuku’s tongue coaxes him to open slightly to gain entry. His cock twitches violently, trapped in the small fabric of the thong and staining it wet with pre-cum. He feels his legs wobble, but he pulls himself together to keep himself upright as Izuku eventually slips his tongue inside him.
Oh GODS.
Never in his life did he think that anyone, not even Izuku, would be giving him a damn rim job. It felt weird, slimy and uncomfortable. Katsuki squirms, trying to find the words to tell him to stop, when he feels that tongue hit that sweet spot inside him, and any protests are immediately thrown out the window as he feels a jolt of pleasure going through his body. His body jerks, he gasps for air, and his grip on the sheets below tightens to the point where he can see the whites of his knuckles.
Izuku seems to pick up on this as he pistons his tongue inside, slowly encouraging him to open up. Katsuki’s breath quickens, his throbbing member ready to burst at any given moment. He curses inwardly at this: usually he lasts longer, no matter what they’re doing. How the hell is he already on the brink of cumming in these damn panties and they barely even started?
Katsuki bites down on his lips, holding back his whimpers and moans as Izuku continues to practically eat him out as he reaches the precipice of his orgasm. Yet, before he can release, Izuku pulls his tongue out so quickly, it jolts Katsuki out of his thoughts.
He does not whine about the loss, fuck you very much.
“Aww, baby, it’s okay,” Izuku says, so toxically sweet it almost gives Katsuki a damn cavity, “I can’t have you cum just yet. We still gotta open your pretty cunt up for my cock first.”
At that, Katsuki is twisted around so his back is on the mattress. He looks up at Izuku, eyes dilated and filled with lust that takes Katsuki’s breath away.
This is a whole new version of Izuku that Katsuki is having second thoughts about liking this.
Izuku smirks down at him as he grabs his legs and practically folds him in half. Katsuki groans at the feeling of his muscles straining. He’s not the most flexible person, but he does work on stretches prior to a workout, so this position shouldn’t be an issue. Yet, in this context, he barely holds it together as he grasps onto the sheets below.
Izuku chuckles as he leans forward, his breath ghosting over Katsuki’s lips. “Hold on to these, would you, baby?”
Katsuki keens, acquiescing to the order as he grabs onto his legs. He keeps his eyes on Izuku’s as he then feels something move the string of the thong aside and prodding his entrance, swirling around the rim and making wet sounds that Katsuki immediately recognizes.
“Fffff—Ah!” Katsuki says the moment one of Izuku’s fingers enters. It’s much easier since he was tongue fucked, but he still feels that pressure as the finger squirms its way inside. His toes curl as he digs his fingernails into his skin. He bites his lips, squeezing his eyes shut as that crooked finger moves around, teasing that spot that makes him see stars.
This continues for however long it takes (Katsuki is not counting the seconds but it seriously feels like forever). Izuku manages to dig three fingers inside him, opening and closing his hole and just barely missing that spot. His cock is still strained in the confines of the thong that all he wants right now is to just get rid of them. He feels it getting wet with pre-cum that the fabric shifts smoothly against the skin, creating that friction he desperately needs.
“Sh-Shit…” Katsuki breathes out, “D-Daddy…”
Izuku chuckles as he licks against his neck. “Gods, you’re so tight. I’m gonna have to use a fourth finger if that’s the case…”
Katsuki whines, no longer caring about his damn pride as he throws his head back against the pillow. “I-I can take it. Sh-Shit I’m close…”
Izuku hums into his neck. “Are you sure, baby?”
Katsuki frantically nods his head, wanting Izuku to get on with the damn program.
He feels those fingers slowly pull out with a loud schlick noise. Katsuki feels his heart pounding in his chest as he relaxes, readying his body for Izuku’s cock—
Only it doesn't come. But what does is something large, wet, and silicone-like slowly entering him. He gasps as he feels every texture, every ribbed part of the object as he opens his eyes to look at what is being put into him. His eyes widen like saucers at what he sees.
It’s a large, dark green Deku themed dildo that is veiny and ribbed in all the right places. It stretches him open until it reaches the hilt. The texture brushes against his spot that the dam immediately bursts. Katsuki screams as he cums, his seed staining the thong and creating a hot, sticky mess.
He doesn’t get a chance to bask in his post orgasm as the leash yanks his collar and pulls him up. Katsuki lets go of his legs as he is guided off of the bed and onto the carpeted floor. He looks up from his kneeling position and Izuku gives him a victorious grin.
“You just couldn’t resist, couldn’t you?” Izuku asks, yanking the leash so his head hits his tight boxer briefs and right onto his clothed cock. “I think you deserve to be punished for that, cumming by just one thrust of a toy in that cunt.”
Izuku tugs at the leash while bringing a hand to Katsuki’s hair, grabbing a handful and keeping him in place. “Now suck it.”
Jesus Christ on a motherfucking cracker.
Katsuki scrambles for the hem of the boxers before he pulls them down, freeing Izuku’s cock. He has seen it plenty of times, has jerked it off on multiple occasions, but this is a whole new context as he submits to its girth and length. He takes a deep breath, trying not to psyche himself out, before he pops the head into his mouth.
Izuku moans as his grip tightens, and it urges Katsuki to move forward. He swirls his tongue around the tip as he slowly inches himself down the cock. Some God given miracle gave Katsuki no gag reflex, luckily, so it takes him no time to sink down to the hilt, his nose tickling the hair around Izuku’s V line.
“Good boy,” Izuku moans out, and he holds his hair tight as he thrusts inside Katsuki’s warm mouth. It startles Katsuki at first, almost choking, but the moment Izuku starts to fall into a rhythm, slow but harsh, his throat relaxes as he starts to enjoy it. He can feel the dildo still inside him, the textures tickling every inch of his insides with each force of Izuku’s movements.
Katsuki feels Izuku’s dick twitch in his mouth, the saltiness of his pre-cum and sweat overflowing his taste buds as he hollows his cheeks and licks every crevice he can reach. He looks up to see Izuku watching with intent, eyes blown up and biting his lip. The hand holding the leash comes down to caress Katsuki’s cheek, wiping away tears that he only just noticed were flowing down, before the hand cups the bottom of his chin. Fingers dance around his neck and Izuku grins as he feels his cock’s indent right at the moment he thrusts inside.
“Fuck, baby,” Izuku says, breathless, “your mouth feels so good. I wish I could stay right here and fuck that hole of yours, thrust deep into that throat until I cum and make you swallow every drop. Wouldn’t you like that, baby? You’d like to swallow all of my cum?”
Katsuki nods his head, not caring about his display in the slightest, tears streaming down his face with his mouth full of cock. The only thing on his mind right now is making his daddy feel good—
Oh…
Izuku slowly pulls his cock out, drool and pre-cum dribbling from his mouth. The sudden loss leaves Katsuki’s head spiraling, unsure where he went wrong. Izuku seems to sense this as he kneels down and gently soothes him, his hands caressing his face as Katsuki whimpers.
“Shhhhh, it’s okay, babe, I know you want to swallow my cum, but I have bigger plans,” Izuku says, smirking as he leans forward, his breath ghosting his ear. “Color.”
Katsuki immediately comes back down to reality, his entire body sensitive and buzzing. He swallows as he answers Izuku’s query, breathing heavily against his neck.
“G-Green…”
Izuku hums and suddenly, Katsuki is yanked back onto his feet by the collar and leash. His legs feel like jello, having been kneeling this entire time, but he doesn’t stay on his feet for long as he is pushed back onto the bed. His back lands on the mattress, the dildo still inside him as it shifts slightly until Izuku lifts his hips into the air and slowly twists it. The friction causes Katsuki to moan and grasp onto the sheets as it rubs on that spot.
“F-Fuck…” Katsuki curses, toes curling as Izuku painstakingly pulls the dildo in and out of him. His cock throbs, still confined in the now cooling, wet thong, and he feels himself on the edge of another release.
Izuku presses kisses along his inner thighs, enjoying the view of the dildo inside of him. “Such a beautiful sight. Your little clit is just begging to be touched, baby.”
Katsuki keens, bucking his hips upwards and forces the dildo further inside. He gasps as a particular bump grazes his spot and he starts to see stars in his vision. Katsuki feels another orgasm on the horizon, and it doesn’t take long for Izuku to realize this as he yanks the thong completely off, his cock free and bouncing against his stomach. Fingers ghost over it, and that is what sends him off as he cums a second time.
He feels his stomach get wet with hot, white cum, staining the lingerie, as he catches his breath. Everything feels fuzzy and warm all around him, his mind buzzing from the high of his second orgasm of the night.
Katsuki feels the dildo slowly pull out, and he whines at the loss, feeling so empty that he almost begs to be full again. However, strong hands grab onto his waist and flip him back onto his hands and knees, jerking him out of his headspace. The leash is tugged, forcing him to lift his head up as he stares at the headboard of the bed.
A low chuckle is heard from above, and those hands slowly travel down his back and grasp onto his ass cheeks, spreading them wide for his gaping hole to be exposed for the world to see.
“You think I’m done with you, baby?” Izuku says low, leaning forward and licking the shell of Katsuki’s ear. “I’m just getting started.”
Oh fuck.
Katsuki doesn’t get a chance to say anything, as he feels Izuku’s cock swiftly enter him. He screams, head thrown back even further, eyes squeezed shut as Izuku starts his brutal pace.
The sound of skin slapping against skin echoes throughout the room. Katsuki grunts with each thrust as Izuku tugs at the leash with one hand and holds onto Katsuki’s hips with the other, keeping him in place. Katsuki can feel his spent cock bouncing uselessly in the air, oversensitive yet still slowly hardening once more. Katsuki grips the pillow, head rushing everywhere as his mind gets fuzzier with each passing moment.
“D-Daddy!” Katsuki shouts, no longer caring about pride or anything, because that ship has fucking sailed a while ago. “Daddy, please!”
He feels Izuku’s cock throb and a hot mouth against the back of his neck, sucking hard and teeth digging into the skin. The pace goes from fast to slow yet hard. Every thrust knocks the air out of Katsuki as he scrambles to keep a hold of the pillow below him.
Izuku lets go of his neck and licks the spot, groaning from behind. “Look at you, begging for my cock. Your cunt is so fucking tight, yet it’s such a greedy little thing, sucking me in like it’s supposed to. You feel so fucking good, I can’t get enough of this hole.”
Katsuki whines, his hole squeezing from the affirmation, and he can feel the grin plastered on Izuku’s face as a moan comes through. “You like that? You like being praised? You love it when I call you a good boy?”
Katsuki nods his head, unable to form words at the moment. Izuku yanks on the leash as his pace quickens, “I need words, baby. Tell me how much you love this.”
“Fuck,” Katsuki shouts, “I-I like being good for—AH!—for daddy!”
“Yeah, baby,” Izuku says, the grip on his waist tightening, “so good for daddy. Such a good little slut that you just need my cock, don’t you?”
“Y-Yes,” Katsuki says, his voice getting slightly higher as he feels yet another orgasm coming.
The leash tugs and soon, Izuku looms over him, mouth right against his ear that sends chills down his spine. “That’s it, baby, just take my cock like a good whore. I’m gonna fill you up with cum and fuck you like a cocksleeve. Is that what you want? You want me to treat you like a filthy cum-dump?”
“Fuck! Yes! DADDY P-PLEASE!” Katsuki shrieks as he cums just from the visual alone. He screams as he stains the sheets below him, the harsh thrusts still ongoing as spurts of cum fly out of him.
After that, Katsuki barely registers anything else. He vaguely remembers screaming with pleasure and Izuku tossing him around on the bed and maybe at some point on the wall or over their desk, he doesn’t know. But during it all, Katsuki’s head flies in the clouds and his brain just stops thinking for a moment. Every part of his body feels tingly and sensitive, and for once in his life, his mind is completely blank and the only thing he registers is pure bliss and pleasure.
Oh…
Oh, is this what subspace feels like?
It feels… Nice…
Yeah…
“—cchan? Hey… Kacchan?”
Katsuki blinks slowly, staring at the ceiling of their bedroom as he wobbles his head back and forth. He attempts to sit upright, but immediately hisses at the soreness of his ass and pretty much every part of his body as he falls back onto the bed, head hitting the pillow he was already lying on. He groans, his arms and legs feeling like putty that will give out any minute. Izuku helps him by hoisting his upper body so he can lean against the headboard. Two ibuprofen pills are handed to him and a water bottle is held in front of his mouth, and he immediately realizes that he is parched. He takes the pills and pops them into his mouth before taking a few generous sips, letting the cool liquid soothe his aching throat.
Katsuki pulls the bottle away and looks over to see Izuku right next to him, taking the bottle and placing it on the nightstand. There is a look on the nerd’s face, and Katsuki doesn’t know how to handle it. It’s a mix of worry and humor, a small smile on his face as he tilts his head. Izuku then reaches over and pulls some of Katsuki’s blonde locks away, the gentleness of his fingertips brushing against his forehead gives him a sense of calm as he leans into the touch. Izuku chuckles as he pulls his hand away.
“You okay, Kacchan?” Izuku asks gently, giving Katsuki whiplash from earlier.
Katsuki blinks, his eyes still trying to focus some more as he starts to come back down from whatever high he was under. “Y-Yeah…” he croaks out, uncaring.
Izuku snorts. “You know, it’s so weird to see it on the other side, subspace. You were out of it for over an hour, I’d be surprised if you remembered anything.”
Katsuki gives him a confused look. “I… I do remember some things, like screaming and the position switches, but… That’s about it…”
Izuku hums, his fingers fidgeting in his lap, his lips forming a tight line. The silence between them feels stifling, and Katsuki has to resist the urge to say something as he waits for Izuku to pick up the conversation again.
It doesn’t take long as he looks into his eyes. “S-So… After I… W-Well, you know, I immediately went into aftercare mode. I know you liked bath salts, so I thought that would help with your soreness. I… I really did a number on your back with those bite marks, s-so I cleaned you up and tucked you into bed. I w-was just waiting for you to come out of subspace so we can t-talk…”
Izuku’s eyes shift, which makes Katsuki narrow his eyes, more questions forming in his head than receiving answers. “Okay… Thank you for taking care of me, I guess…”
Izuku perks up at that, a small tinge of pink forming on his cheeks. “Y-You’re welcome, Kacchan…”
Katsuki still feels a bit lightheaded, so he does his best to put a scowl on his face and toss a pillow at him. Izuku squeaks at the contact, looking at him with genuine shock.
“You’re a fucking menace,” Katsuki sneers, taking the pillow back and curling into a ball with it. “Where the fuck did you learn all of that dirty talk and shit?”
Izuku blinks. “F-From you? I’ve been taking notes and—”
“Of course you have,” Katsuki says, not a drip of surprise in his voice, “but go on.”
“A-Anyway, I’ve been observing your m-mannerisms whenever you’re the Dom and I just kinda… Went with it? I-I also tried to hone in on your own personal kinks, l-like praises, so I may have milked that a bit during our scene…?” Izuku goes to stand and walk toward the dresser, digging around in the top drawer. “Anyway, I didn’t think you’d be into it as much as you were, b-but I’m glad you enjoyed it, since you came five times…”
Katsuki’s eyes widen, his mind practically being slapped back to reality. “HAH? I came—Fuck no! I only came three times! The deal was—”
“That I needed to get you off more than three times,” Izuku says, looking back with a menacing grin. “While you were in subspace, you came two more times before I did. I was shocked you still had any left, but wow, you must have really liked it.”
At that, Izuku pulls out what appears to be some sort of magazine and walks back to the bed. He tosses it toward Katsuki and, upon picking it up and inspecting it, he realizes that it’s not a magazine…
But a dress catalog!
Katsuki turns to look at Izuku, who gives him a smug look. “I like the long, green one on page thirteen, but feel free to choose any of the dresses in them. The Gala is in two months, so I’d start looking now.”
And with that, Izuku waltzes into the bathroom with a pep in his step. Katsuki watches in sheer mortification before Izuku goes to close the door. He turns his head back to look at Katsuki, winks, and shuts it closed, leaving Katsuki alone in the bedroom with the damn catalog.
This motherfucker is gonna pay one day.
