Chapter Text
It was hot. Burning hot.
Doing hero work in 90 degree weather and 80 percent humidity was not for the weak, but Izuku supposes that it’s part of the job. Some horrid weather would never stop him from helping people, not if he could help it.
So when his mid-afternoon patrol with Kacchan finally ended, he was relieved. They had just finished up detaining a villain who had been wandering around with an odd quirk, harassing people at night and being a general nuisance overall. It was a mistake to be en route with the Wonder Duo that day, especially when Kacchan was in a more irritable mood than usual with the heat.
Izuku had just pinned the villain to the ground and knocked out, and an officer was approaching with quirk canceling handcuffs ready to detain the latter. Izuku wiped the sweat from his forehead— in the midst of summer, it felt like the mecha suit his class had gotten him radiated heat inside out. But he couldn’t complain, it helped him do what he loved most.
“Deku,” Kacchan called a few feet away, sitting in the back of an ambulance getting patched up, but overall fine, “You good over there?”
“Yep! Lemme just wrap this up and we’re good!” Izuku called back. He could see the sheen of sweat on Kacchan’s forehead too, exposed by the EMT workers pushing back his hair to patch him up all the way. Just a few scrapes and bruises, same with Izuku.
“Hero Deku?” A woman with glasses and a notepad approached him, very much dressed in professional attire, “We’re with Tsukauchi’s analysis team, we’d like to ask you a few questions on the perpetrator’s quirk, if you don’t mind?”
Izuku approached her once the officer was in range to take over, “Sure, I don’t mind!” He removed his gloves in order to let in a bit of air and cool off.
“We understand that the villain has been going around recently harassing people late at night with his quirk, but we’re not sure the details of it. Did you have any of your own theories?” She put a pen to paper and looked up at him expectantly.
“Well, although we didn’t battle or anything I actually did have a few theories myself. It could be some sort of drugging quirk, or paralyzation quirk.”
“Mhm, and what makes you think that?”
“He specifically targeted vulnerable victims, who were weak afterwards based on what I heard from the profile debrief. It could be something similar to Stain’s Bloodcurdle ability, but I’m not sure what the activation factor could be. But I think he would need to move in close on his targets—”
“DEKU! Behind you!” Izuku heard Kacchan’s voice rang in the air. Panic set in.
Out of pure instinct Izuku pushed the investigator to the side and spun around, ready for a fight. He came face to face with the villain conscious again, charging at him with a crazed look on his face, screaming nonsensically.
In a split second, Izuku ducked, swept the man off his feet, and pinned him to the ground, throwing his head against the concrete in an attempt to knock him out again. He was face to face with the villain, who had been caught off guard, and was slowly blacking out again.
“Y-you..you’ll regret..doing..this..” The villain clawed at Izuku’s hands around his neck, as he slowly went limp. When Izuku was sure the villain was fully unconscious this time, he released him and stood back up. The woman behind him was slightly dazed but thankfully unharmed. It seems he really was some random hooligan running around being a societal nuisance.
“Deku!” Kacchan ran over to him, and immediately began checking him over. “That fuckin’ bastard, I can’t believe he got up again.”
“Heheh, it’s fine Kacchan. He wasn’t too dangerous anyways.” Izuku smiled at his husband’s antics, and his heart slightly thudded at the fussiness the blonde had over him after every villain encounter. It was so cute.
Kacchan huffed when he deemed Izuku unharmed and placed his hands on his hips. “Well let’s fuckin’ clock out, I need a shower.” Kacchan stalked past him, throwing a glare at the police officer who had been unable to restrain the villain. After the officer hurriedly and profusely apologized, saying he would talk to them later, they were on their way back to the agency.
--
“Today was fuckin’ gross,” Izuku heard Kacchan say as he exited the bathroom, toweling off his still damp hair. When they got home, they had immediately turned the AC on to full blast, made a light dinner, and took a long shower to rinse off the dirt, dust, and sweat from today. They both agreed to just put on some random movie and fall asleep watching it in bed together.
Izuku chuckled, “Yeah, it was super hot. The news said it’s gonna be like that for the rest of the week, too.” He huddled up in the blankets and scrunched his knees up. Katsuki threw his towel onto a chair and settled into bed next to him.
It was mindless white noise, really. Well, Izuku was invested in the content, but he knew Kacchan used it as white noise to fall asleep against him. It was their routine ever since they moved in together. Come back from patrol (or teaching for Izuku), do chores, cook dinner, schedule plans, and fall asleep together with a video as background noise. Kacchan always fell asleep first, as per his ‘old man sleeping schedule,’ Izuku liked to call it; he kept a routine since high school.
It had been a solid 40 minutes or so before Izuku felt his own eyelids drooping, eyes focusing and unfocusing every few minutes on the screen. Kacchan was slumped against him already, arms grappled around him, with his face buried in Izuku’s neck. He could at no point tell if the man below him was already asleep, but Izuku quickly closed the laptop and turned to dim their bedside light.
Once the room had darkened, he shuffled back down to rest his head against Kacchan’s chest, snuggling until he fell asleep. The rumble against his ear registered before Kacchan’s voice did.
“Hey ‘Zuku?” Kacchan’s groggy and tired voice spoke above him. He could tell the blonde was half asleep and buried in Izuku’s curls, muffling his voice.
“Mmm..Yeah Kacchan?”
“You gotta be more careful.”
“You mean that villain at the end of patrol? It’s okay, I got him, didn’t I?” It took a few seconds before Kacchan responded back, tipping over the edge of sleep, “Mmf, yeah…Just don’t let some one-liner villains put their hands on you, baby.”
Izuku cracked open his eyes a little with a faint blush creeping up his neck. It seems like he’ll never get used to Kacchan calling him ‘baby’, or ‘husband’, or anything of the matter. In public, he would never say anything like that, especially around their friends. But in private, behind closed doors, wrapped up in bed with each other, Izuku saw sides of Katsuki no one else would ever see: the soft, the ugly, the sorrow. Izuku had lived his entire life seeing every aspect of Kacchan.
“Don’t worry Kacchan, I have you after all, right?” Izuku whispered into the blonde’s chest, but more so said it to himself. He then heard light snores, signifying that Katsuki had passed out. Izuku smiled, and fell fast asleep himself.
--
Katsuki awoke with a thud. Or more like a ‘someone might be in my house’ thud. He had wanted to turn over, forget that there may be some asshole breaking into his apartment right now, and go back to sleep. Because, well, who’d be enough of a dumbass to rob the apartment of two top heroes? But when he shifted over again, a low brightness hit his closed eyes, with the blackness of the room suddenly becoming slightly illuminated with a light from another room.
Katsuki grumbled, and had to finally acknowledge that someone might actually be breaking into his place right now. With his right hand, he rifled through the blankets to make sure a Deku was still within range, in case of emergency. But after a few seconds of emptiness and the realization that the warmth against his side was gone, Katsuki finally cracked his eyes open to see what the hell was going on.
The first thing he saw was the analog clock on their bedside, reading 2:33 AM. Fucking great.
Next, he addressed the lack of a sleepy nerd beside him. Staring into the darkness of their bedroom for a bit, he groggily got up from the bed, finding his footing on the cold wooden floor to investigate the light coming from their shared bathroom. Maybe Izuku just got up late to use the bathroom, but that wouldn’t explain the sudden thud.
With eyes still half closed, he ventured into their bathroom, with the fluorescent light fully hitting him as he entered. He already sensed Izuku’s presence there, and was ready to drag him back to bed.
“The fuck are you doing ‘Zuku? Come back to bed already.” Katsuki yawned mid sentence, and leaned against the bathroom door frame. He expected a squeak of surprise and then a body of warmth returning with him back to slumber. Instead, after a few seconds of silence with no response from the nerd, Katsuki finally cracked his eyes open all the way.
“Hey, what are you—”
“K-Kacchan...”
Katsuki woke up immediately at the sound of Deku’s shaking voice. It sounded like he was on the edge of crying. He snapped his eyes open to see him hunched over the sink, one hand clasped over his mouth, shivering. He rushed up to grab a hold of the other man’s shoulders to face him.
“Deku? Hey! Izuku? Hey, what’s wrong?”
“Nghn..w-wait...don’t…”
With a better view of Izuku’s face, Katsuki noticed his tousled hair, with sweat making curls stick up. His face was reddened, making freckles stand out even more. Katsuki noticed he also wasn’t looking him in the eye, instead with a hazy gloss over viridian, a wetness shining through. Izuku was eyeing the hand on his shoulder instead, and was slightly panting.
“Are you— okay? You’re sweaty as hell. Is it the heat?”
“I-I’m..I don’t know.. All my senses feel..t-too much though..”
Deku’s voice was scratchy, and face flushed as if he had ingested bottles of alcohol. It almost looked like he was—
“Are you fucking hard right now?”
Deku immediately stuttered and flared up more, if it was even possible to get more red than he already was.
“I don’t—that’s— Ah!”
Katsuki palmed the front of Izuku’s sleep shorts to test his theory. Low and behold, the nerd seemed to be at a half chub, just as expected. He let out an obscene groan when Katsuki got closer and backed him against the sink counter.
They both froze at the noise which came out of Izuku’s mouth.
That was fucking filthy.
Izuku dropped his head into his neck to try and hide his embarrassment. The heat from his cheeks contrasted wildly to Katsuki’s cool body.
Katsuki smirked.
It had been weeks since he and Izuku had gotten intimate. Between climbing the ranks back to top 5, the nerd’s teaching schedule at UA, and all the other nonsense that comes with being a pro—month long missions, press conferences, and photoshoots—they actually hadn’t had sex in a while. A quickie here and there in their offices didn’t count, in Katsuki’s opinion.
On top of that, it was usually Katsuki who initiated first. Since the beginning of their relationship, Izuku had always been shy during sex. He’d cover his face with his arms so that Katsuki could never see at his tear-stained cheeks and would just go along whenever Katsuki wanted to. He would never force him, of course, he loved taking the lead after all. But seeing Deku flushed up and half hard right now made him suspicious. The nerd never got horny off of nothing, not without Katsuki around.
“I-I don’t know why I feel so..hot.” Izuku mumbled, talking into Katsuki’s collarbone, “S-sorry..”
“Hey don’t fuckin’ apologize, it’s fine.” Katsuki wrapped his arms around Deku, forgoing the contact before. “Hey, didn’t that villain from today have some sort of drugging quirk? Is that what this is?”
“I hadn’t thought about…about that. It could be possible that I miscalculated what it could be.”
“Well, it’s fuckass in the morning right now. We’ll call Tsukauchi to figure out what this shit is in a few hours.”
Katsuki slightly deflated, he didn’t want to fuck if it was the under the influence of some quirk. It felt wrong in some sense, if Izuku just felt more sensitive than usual, that didn’t give him the green light to do whatever he wanted, no matter how long they haven’t slept together. As long as it’s not physically harming him in some way, he could hold off until the quirk wore off. He turned to leave the bathroom and flicked off the lights.
“C’mon let’s go back to bed. I still got patrol in the morning.”
A hand wrapped around his wrist; it was extremely warm.
“Kacchan..”
Katsuki turned to see whatever the hold up was, before he was pushed back into the bedroom by a hard kiss. He stumbled before regaining balance as Izuku kissed him hard, biting down on his bottom lip and wetly devoured his mouth whole. Katsuki quickly returned the same vigor, leaning into it and looping his arms around Izuku’s waist again. His eyes peeled open to see Izuku red, flushed, and sweaty, trying to melt himself into Katsuki as much as possible.
It was after a few seconds of lewd wet mouthing that they pulled apart panting for air. The look Izuku had on his face was frankly inappropriate for one, definitely not the so-called ‘family friendly Hero Deku’ Japan praises about.
“Hah…you know how downright filthy you look right now?”
Izuku doesn’t respond, just keeps looking at Katsuki with a fire in his eyes, before rutting against him with his hips. Katsuki jolted and looked down at their point of contact.
“Kacchan,” Deku whined. He fucking whined. “Can we please do it right now?”
Shit. It wasn’t often Izuku would start. He was mostly all sunshine and family friendly vibes. When Izuku did get even slightly suggestive, it was fucking hot. But, even then…
“You’re under some sort of quirk right now that we don’t know. As much as I’d love to fuck you into next week, let’s wait until we know what you’re under. Okay?”
“No! I-I still know what’s going on, i-it’s just— I just feel lonely when we’re not touching,” Izuku mumbled. Katsuki sighed and backed himself sitting down on their bed and held out his arms for Izuku to jump into. He began rubbing his face against the juncture of Katsuki’s neck, as if any contact at all was stimulating enough for him. Katsuki rubbed circles into his back, kneading through his sleep shirt.
“S-sorry, it just feels like…I’d be using Kacchan when it’s convenient for me right now..”
It was so rare to have Izuku proactively arouse him sexually. And he was initiating it first. To hell if Katsuki didn’t think this quirk was convenient.
Katsuki titled Izuku’s chin up to eye level, he still had a shiny gloss over his eyes.
“You sure you’re okay with this? I might not be able to hold back.”
Izuku’s eyes lit up, and in response pushed Katsuki back onto the bed by the shoulders, straddling his thighs and surging forward to kiss him again. Katsuki gripped Izuku’s thighs to steady him as they made out again. Eventually, Izuku backed away for air, rolling his hips back to grind with the front of Katsuki’s clothed dick. The blonde groaned in reaction and gripped harder around Izuku’s thighs.
“Fuck me already, Kacchan.”
--
There had to be a limit to how convenient this quirk was.
For all the talk Izuku put up earlier and backing Katsuki first, he was actually still quite shy actually having sex. Katsuki loved that about him though. No matter how strong Deku was to the public, a pillar of hope, he would still become undone under Katsuki’s hands.
They had switched positions, Izuku splayed out on his back and Katsuki above him, with one knee wedged between his legs to rub against his half hard cock. They sloppily mouthed for a few more minutes before pulling apart, a lewd line of their saliva connecting their mouths. He wiped off some spit on Izuku’s mouth. His kiss bitten swollen lips wrapped around Katsuki’s thumb, sucking on the digit. Another finger was added into his mouth, digging deeper into the back of Izuku’s throat until he felt like he was choking.
Izuku moaned around Katsuki’s fingers, tears welling up in his eyes as he lapped each digit with fervor. All Katsuki could focus on were those pretty pink lips sucking, and would put it to good use later.
Eventually Katsuki removed his fingers from Izuku’s mouth, who had grown quite impatient.
“Kacchan, fuck me already. Please, please.” Izuku desperately rolled his hips against Katsuki’s knee again to find any semblance of friction, he reached up and pulled down the hem of Katsuki’s shorts.
It was a jumble of limbs, Izuku had never been so impatient to fuck before, and it turned Katsuki on all the more. He loomed above him, grabbed the nerd’s hands that were tugging on his shorts and pinned them above his head. Katsuki slid just one of his hands down to pin Izuku’s wrists, using his right to pull off both his and Izuku’s sleep pants and briefs.
Even in the darkness of the room, Katsuki could see how flushed Izuku’s cock was, just as much as his face. He’d jerk off to that later in the shower, right now he had a horny nerd to satisfy post haste.
At the feeling of warm hands near his legs, Izuku spread his legs further apart, bringing his knees up to his chest to give Katsuki better access. Katsuki took the invitation to start tracing around his entrance. Katsuki eyed the tight, pink hole, unused for weeks since their last night together.
Deku whined again, “U-ugh, Kacchan! Fuck me already please! You don’t have to prep— ah, fuck!”
Katsuki plunged two saliva coated fingers into Izuku’s entrance, viciously pumping them back and forth to hit his g-spot each time. He furiously rubbed at the area, with pornographic squelching. He curled his fingers once, and Izuku let out a choked yelp.
“Calm down idiot. I’m not tearing your asshole tonight, keep whining and I’ll leave you with blue balls.” Despite that threat, Katsuki had no intention of doing that. This opportunity would not be wasted.
Izuku quieted down after that, slowly devolving into obscene moans and whimpers as Katsuki added another digit in, going in and out at a rapid pace. Izuku’s hands writhed as he desperately searched for something to latch onto, but Katsuki kept his wrists in a punishing hold on the mattress.
Once Katsuki had fucked every finger into Deku, stretching his hole in preparation for his cock, the nerd had already melted into a puddle of precum and sweat. He was definitely way more sensitive than usual. They were both panting, the heat from prep alone was getting to their heads.
Izuku felt a sudden rush of air inside as Katsuki removed his hand, whimpering loudly at the loss. It was soon replaced by the sudden thrust of his cock, bottoming out in one motion. Izuku arched up towards Katsuki, who hit every sweet spot between his velvety walls, sucking him in further and further.
Katsuki groaned at the feeling, the tight, wet heat wrapping around his dick as he waited a few more seconds to enjoy the bliss he felt. He snapped back into reality when he saw Deku desperately trying to fuck himself back and forth onto his cock.
“Okay baby,” Katsuki said in a husk voice. He forgoes holding Izuku’s hands above his head and shifts them both to holding his thighs, gripping them with enough force to bruise, “It’s okay, let Kacchan take care of you.”
Izuku moaned at the use of Katsuki using his own nickname, and is quickly replaced by the sound of skin hitting skin as Katsuki snaps his hips back and plunges back in again. He sets a rigorous pace, knowing that if it was anybody else, they’d cum in seconds. But it’s Deku, and he knows the nerd can take whatever he gives him.
With his hands released, Izuku grips onto the bed sheets, throwing his head back to expose the expanse of his tanned neck, red, but completely unmarred. Katsuki would have to change that fast.
Just as he kept fucking into Izuku, he leaned down and latched onto his neck, sucking dark hickeys from ear to collarbone. He wanted to claim, he wanted to brand. He wanted to show that Pro Hero Deku, whoever the public knew him as, was taken. The thought invigorated Katsuki more, thrusting harder and deeper.
The bed shook at the force he was going at, and Izuku was completely gone by now, whiny demands turned to random gibberish and the occasional out of breath ‘Kacchan’ thrown here and there. His eyes welled up with tears, everything felt much more. Whatever the quirk was doing, it made Izuku ten times more sensitive in all areas, so when Katsuki fucked into him, he could almost feel it coming out his throat. With the addition of teething and marking Izuku’s skin, the sensations overwhelmed him, and he chased that pleasure.
His mind was a muddled mess by now, Katsuki fucking him even faster, his thighs jumping up and down from the force. His neck was starting to become more bruise than skin. All Izuku could let out were fucked out moans and whimpers. He threw his arms around Katsuki’s neck, pulling him in further to melt into each other as much as possible.
“Hah..hah, K-Kacchan…Ah..Ahn…—acchan..” He whimpered out, there was too much, it felt like too much. He could feel himself reaching his climax already, knowing he would cum from Kacchan’s dick alone. It turned him on more, throwing his head back again to allow more access to his already ruined neck.
“Fuck—baby, you feel so good…So hot and tight, be good for Kacchan, yeah?” Katsuki whispered into his neck between bites and kisses, still fucking at a now sloppy speed. Each moan he elicited from Izuku’s mouth built him up further, making him go faster. He gripped the younger hero’s thighs and pushed them further back to his chest, creating an angle to fuck even deeper into.
He started stuttering in pace, losing himself. With one final thrust, Katsuki was sent over the edge, cumming deep inside, painting those walls white. Izuku came at the same time he did, his dick rubbing between his and Katsuki’s bodies. He came across both their chests, some landing on his bruise riddled neck and onto his eyelashes.
Katsuki collapsed onto the smaller hero, who prompted a small whine before letting go of his neck. Katsuki continued to thrust his hips shallowly, trying to milk every last drop before slipping out. He buried his face in Izuku’s neck, not bothering with eye contact. The air was silent, apart from their heavy breathing.
After a few minutes of mutual panting, Katsuki looked up to see Izuku thoroughly fucked out. His hair tousled against their mattress and body flush red, his eyes were starting to droop too from exhaustion.
Katsuki settled back against Izuku’s neck, throwing the blankets over themselves. Hopefully, the quirk would have worn off by now. It had been a while since they had gotten that steamy. He would think about it more in the morning.
--
“It’s fucking what.”
“It is an aphrodisiac type of quirk.” A voice spoke from the phone, “Apparently it intensifies all feelings of lust and sensations.”
Katsuki, who, although had great sex a few hours ago, woke up annoyed to a call from the detective agency yesterday. The woman Deku spoke to contacted him at ass 'o'clock in the morning. Speaking of which, the nerd was still asleep, likely too tired from last night (this morning?)
“Alright, how long does it last?”
“So..that’s the part we’re trying to figure out right now,” the lady spoke again, “The user won’t give us many details, and the info we have now was from past victims so far. They explained it was supposed to incapacitate their cognitive abilities for enough time for the villain to lure them away, like completely knocked out. Did Deku show any signs last night? The villain did make skin contact with him, no?” Katsuki sighed, so that’s what the whole deal was about. “Well he was still awake, just really fuckin’— well…active, I guess.”
The woman could probably tell from the tone and implications of Katsuki’s answers what that meant, and said again, “Perhaps it was because Hero Deku did not make a ton of contact with the villain, as a lot of victims said he would need to grab them by the shoulder or neck for his quirk to properly work all the way. I’m guessing Deku held off on the effects until late last night.”
Katsuki scoffed, what kind of dogshit scum goes around doing what he did with a quirk like that? It pissed him off that he had touched Deku at all, now knowing what the intended use of the quirk was.
“We’re not sure how long the quirk lasts, but we’ll call back to let you know when we figure it out, Dynamight.” With that, the detective hung up the phone, and Katsuki blinked blearily at the sun slowly shining through their windows. It was 8:30 AM now, and Katsuki had a tradeoff patrol shift at 10, so he could bask in this comfort a little longer. Katsuki threw his phone somewhere across the bed (he’d find it later), and snuggled back in the covers with Izuku, who was still peacefully sleeping.
--
Katsuki woke for the third time that day, albeit a little more groggily than normal. He had been woken up in short intervals throughout the night, so god forbid if he decides to rest his eyes a little longer. But what caught his attention in his dazed out state was the slight movement against his stomach, it felt warmer than usual.
Katsuki blinked his eyes open again to find the most arousing picture his mind could ever conjure. Izuku, who was still basking in the afterglow and early morning light, sat on his stomach, rutting his dick against it. The nerd was still naked from the bottom down, and his hands rested on Katsuki’s chest as he straddled his body and tried to rub one out on his stomach.
God that’s fucking hot.
Deku was so caught up in chasing another orgasm that he hadn’t noticed Katsuki awake again, his eyes were shut and head hung low to try and generate some friction. He would normally jerk himself off, but hey, his husband was right there next to him, and he knew Katsuki had a morning shift so he wouldn’t wake him up and would try to do it himself. That was a failure, Izuku realized, as he felt warm palms grip his thighs once again. He gasped, lifting his head up to meet deep crimson eyes, looking at him hungrily.
Suddenly, the reality of what Izuku was doing hit him at once. He flushed up and began panicking.
“K-Kacchan! I—uh, s-sorry! I’ll go to the bathroom and— uh—”
Izuku started stammering, his hands flailing up from Katsuki’s chest as he failed to get out a response to the blonde’s expression. Katsuki only grinned, like he had caught Izuku doing something bad and was trying to lie his way out of it. Getting off by himself when he could have just woken Katsuki up for round two. And there’s never a round two.
Katsuki smoothed one hand around Izuku’s thigh, still looking up dreamily at him, before tracing around his still raw rim. That shut Deku up immediately, and he shuddered at the sensation. Katsuki smirked up at him as he continued the motion, using two fingers to trace up and down in a V motion, circling Izuku’s hole, still slightly dripping of cum from earlier.
“More excited than usual, huh Deku?” Katsuki still maintained eye contact as Izuku’s thighs trembled on his stomach, using his thumb to flick the edge of his entrance. Deku had given up eye contact at this point, shutting his eyes from earlier embarrassment and just how easy Katsuki could read him, he was still flushed red, but not nearly as much as last night.
“I don’t know why…I feel like this, my body feels hot still.” Izuku mumbled out, now fucking his own hips on Katsuki’s stomach, anticipating a pale finger to enter him. “S-sorry Kacchan, I know you have..hah…patrol soon.”
He teased Izuku’s hold a little more before fucking a finger inside, he intended to throw him over the edge with his hands alone. It slipped in with little friction. Still loose.
“You kidding? Don’t apologize, I’d wake up to you on top of me any day.” Katsuki had a devilish smirk on his face, pulling his finger out slightly before sinking back in again, hitting Izuku’s prostate, which made him throw back his head at the feeling. His stupid pajama shirt that said “sleep shirt” on it was now staining with sweat and dried cum.
Izuku leaned forward and rested his head under Katsuki’s, bracing his hands against his chest. From above the green curls, Katsuki saw how beautifully Deku’s back arched low towards him, a slope that built up to his round ass, which made pornographic squelching sounds as Katsuki fucked his finger in and out again.
Deku had his eyes shut, quietly whimpering and panting hot breaths against Katsuki’s pale neck, letting his husband fingerfuck him slowly until he came.
Katsuki looked down at Izuku’s scrunched up expression, biting his lip, whimpering at every prod at his prostate Katsuki aimed at. Katsuki slowly dragged out a single finger before curling back in, savoring the hot, wet feeling around him.
God, this was erotic. Deku continued lightly rutting against his stomach, gripping his shirt as he occasionally fucked himself back on Katsuki’s finger. They rarely had sex in the morning. With such insane schedules, one of them was already out the door before the other woke up. And most of the time, Izuku had to get up early to get to UA in time for morning lessons. He only taught part time now in the mornings, but luckily it was Sunday, meaning they could enjoy themselves a little before Katsuki had to clock in.
“You look so good like this baby,” Katsuki lazily whispered into Deku’s ear, slightly nipping his lobe, “Are Kacchan’s fingers enough for you? You gonna cum from just this?”
Katsuki’s teasing seemed to send Izuku over the edge, causing the younger to stutter out moans before cumming over his and Katsuki’s shirt once again. Izuku gripped his shirt tight, seeing white spots overtake his vision.
Katsuki slowed, pulling out and tracing his finger around Izuku’s red rim again, making his hips stutter. Izuku’s thighs relaxed on the sides of his stomach. Katsuki wrapped both his arms around Izuku, resting on the small of his back.
A few moments later, Izuku lifted his head and rested his chin on Katsuki’s sternum, making eye contact.
“Sorry for waking you Kacchan, I just—”
“It’s a quirk.”
“Huh?”
Katsuki brought a hand up to lazily comb through Izuku’s matted curls, “Got a call from the detective yesterday. That last shitty villain on patrol quirked you. She said some kind of lust inducing quirk that heightens all your sensations.”
Izuku’s eyes widened, “What a weird quirk, how do you even discover something like that?” he chuckled. His eyes still had a sheen over them as he stared dreamily at Katsuki, resting his cheek on his chest. He sighed, “Explains what I’ve been feeling then.”
Katsuki smiled back, “Best fuck we’ve had in a while. You okay baby?”
“Mmf. Yeah.”
“Maybe take the rest of the day off. They said they’re not sure when the quirk is supposed to wear off.”
“Are you sure? What if—”
Katsuki stopped that thought with a sudden kiss to Izuku’s lips. It was sweet and deep, not as voracious as before, but still with love.
“Hey, we talked about this. You’re not the only hero around.” Katsuki pulled back, “You don’t have to do anything alone, me and the extras step in when things get too much.”
Izuku’s eyes softened, his concerned expression melted into a smile. He nuzzled his face into Katsuki’s chest and laughed, “Don’t call our friends extras Kacchan…but thanks. I have you after all.”
Katsuki hummed, rubbing Izuku’s back. They basked in the early morning a little while longer. Heat radiated from his chest, and he felt Izuku’s lips shift into a smile.
It was 30 minutes later when Katsuki finally dragged himself out of bed, got dressed and headed out for patrol. Deku, of course, whined the whole way out, sitting still bare ass on their bed, pouting at his husband. But of course, villains waited for no one and heroes had to do their job. Katsuki was amused by his antics. He loved this possessive, clingy side of Izuku.
He hoped to come home earlier today to that ass still in bed.
--
It had been 2 hours since Katsuki left. And Izuku was really, really horny.
He should have known, really, that something was off after his encounter with the villain from yesterday. It wasn’t until way later that night when his body felt hot and tingly, and suddenly everything was turned to max sensitivity.
They hadn’t had a lot of time to have sex recently; blowjobs and jerking each other off didn’t count, according to Kacchan. They fucked last night (this morning?) and it was a great stress reliever, the plus side was that his body felt a lot less sensitive right after. And Kacchan had gotten him to cum before going on patrol this morning too, so theoretically, everything should’ve been fine.
Except not.
It was a good idea to take the rest of the day off. He never felt so sexually depraved before. Izuku felt a hot sensation begin to pool in his stomach, leveling down to his crotch area. He had just gotten off not even 2 hours ago.
Izuku liked to think that he was the less sexually promiscuous one of him and Kacchan. It made sense, as the sweetheart and kid friendly hero. The media ate their dynamic up. The hottest, sexiest bachelor pro hero Dynamight and the pro hero who you’d want to have as your grandson Deku. In personality as well, Kacchan was explosive while Izuku was polite and all smiles. It’s what their PR team built their brand off of.
So Izuku felt a little filthy as he trailed his fingers down to his still loose hole.
He had come twice in the last 12 hours. Was he really that eager to do it again?
He laid back on their bed, hair messed up pressed against a pillow, and lifted his knees to get better access. He slipped a finger in with no resistance, and continued again until four were in. He could feel the dried cum from earlier as he fingered himself. He imagined it was his husband fingerfucking him for the second time today. He imagined maybe Kacchan would come back and find Izuku getting off by himself. The thought turned him on.
“Nnghh…Ah...ah..K-Kacchan..” Izuku moaned into the air, he wrapped his other hand around his cock, and began sliding up and down at a similar pace, a spout of precum leaking onto his hand. He thumbed his slit and gripped himself a little tighter. He thought of all the dirty things Kacchan would whisper into his ear as he increased his pace.
“Come on Izuku, a little faster, yeah?”
“You look so fucking good baby, prepping yourself for me.”
“Nerdy slut just couldn’t keep his hands off himself, playing with your cute leaking cock like that.”
Izuku came in an instant and cried out. His vision whitened out again. That was the fastest he’s ever come. His fingers pulled out and he felt the hot white dribble down to his stomach and between his fingers. His dick twitched again.
Izuku breathed heavily as he recuperated. He wanted more.
He tried to put his lust on hold for just a second. He needed to evaluate what this quirk did. He turned over in bed on his stomach, reaching for a bottle of water on the nightstand.
Obviously some kind of lust quirk, that amps up sexual stimulation and drive, but never feeling satisfied. He’d come three times now, but Izuku still wanted, needed more. Usually jerking himself off or playing with his ass was enough, but he’d only really gotten some temporary relief with Kacchan.
He opened the cap and downed the bottle in one go. His eyes dropped to the floor, around the bottom of the nightstand.
Oh.
Oh right.
Izuku dropped the empty bottle to the floor, and leaned down to open the bottom drawer of the nightstand.
Maybe this’ll work?
--
His sensitivity was at its highest, eyes welled with tears and his hole was twitching as he pushed the dildo in again. Izuku panted into the air, fucking himself deep with it.
When they were just riding their high from their debut as pro heroes, some random company had sent him and Kacchan a box full of toys. Izuku originally thought they meant hero plushies and keychains. Not vibrators and dildos. That was an interesting package to open.
When Izuku brought it up one night after patrol; Kacchan nonchalantly declined.
“Why the fuck do you need a fake when you’ve got me?”
Well probably for this reason, which Izuku thought would never happen.
He choked out a silent moan as he gripped the base of the black and orange toy and shoved it deeper. Izuku saw through his blurry tears the cock disappear in and out of himself, his hole greedily taking and taking. This toy was longer than Kacchan, but not as thick, and Izuku tried to chase that same high by pumping faster.
He took it out almost completely, spreading his legs wider to get a better angle. Knobby scarred fingers trembled, holding the 9 inch toy, letting the length linger across his hole. Izuku bit his lip and teased himself, shallowly pushing it in and out around the tight ring of muscle, building himself up. Then he shoved all of it back in, angling his hips up into the air, aiming for his prostate with each consecutive thrust. He kept going faster and faster with each flick of his wrist, his ass clenching tightly with little give.
“Fuck…fuck..hah..ah! S-so..deep..so…good” Izuku pushed his head back into the pillow as he tipped over the edge for the fourth time today, spurting rope after rope of cum over his already stained stomach. Izuku let his hands go limp, and the fake cockhead fell out of him, he panted as he just took in what he did. Cumming 4 times in the last 24 hours.
He felt better, it seemed like he needed actual penetration to find some temporary relief. Izuku expected this wouldn’t last and he would be hard again soon, but his body, after orgasming so many times, finally started to feel tired. His eyes drooped in exhaustion as he lay out on the bed, sheets tangled and blankets mindlessly sprawled across him. He decided to shoot Kacchan a text before falling asleep. He turned over and reached for the nightstand again.
>> Miss u Kacchan! Don’t worry about me, do your best today!
>> Love you (´⌣`ʃƪ) !
Typing bubbles appeared on screen.
>> love you too nerd
Izuku smiled dopily at his phone. He loved him so much, and Kacchan was never too busy for him. His words.
Kacchan was always by his side, ready to do anything for him. Even when Izuku mistakenly rejected him that night at the izakaya, Katsuki was by his side the very next day, pretending nothing was wrong. They talked about that night later, and Izuku didn’t realize Katsuki was not only asking for a hero partner, but a partner for life.
After the Wonder Duo’s signature move of miscommunication, they went the whole nine yards, moving in together, getting back into the hero game as rivals, and confessing. It only took 20 years, but, to each their own.
After becoming an official couple, Katsuki spoiled him relentlessly, picking him up after school, matching as many patrol schedules as possible, buying him every hero figurine imaginable, cooking meals for him, demanding days off together, and making love in between their hectic schedules. A lot of the time, Izuku wouldn’t be allowed to do anything in bed, just laid there and took whatever Katsuki gave. He didn’t mind, really, as long as they were close Izuku was okay with anything. And Katsuki wanted him to just relax and feel good, pampering him even more.
He loved the attention Kacchan gave him, it made him feel special and truly loved. Even on a busy work day, he would respond to Izuku’s calls and texts in less than 5 minutes.
Right before Izuku fell asleep, he decided to surprise his lover when he got home, fishing out something else from under the bed that had been forgotten about in the toy package. He wanted to be ready and prepped for Katsuki as soon as he got home.
And let the droop of his eyelids overtake him.

Read 12:31 PM
Katsuki refreshed the page again to see if Izuku had texted him again. He swiped up once, twice. Nothing.
“Trouble in paradise ay, Bakugou?” Kirishima elbowed his shoulder, “You’ve been staring at your messages with Midoriya for like 10 minutes now.”
“Nah, just makin’ sure the nerd didn’t die,” Katsuki gruffly mumbled, his left hand clutching the takeout bag as he scrolled up again. He had finished a 10 hour shift with Kirishima and decided to just get takeout today. It was getting late as they walked back to their respective apartments and he was exhausted. His mind wandered back to Izuku again, “Got quirked yesterday. I forced him to take a mandatory rest day.”
“Oh yeah, I heard about that. He’s okay right? We couldn’t get much outta the detective.”
“Yeah, he’s… fine.” Katsuki said; he hadn’t specified exactly what type of quirk Izuku had been hit with. The woman from this morning hadn’t called him back either, so he himself was still kind of in the dark. “Just kind of tired.”
“Aw man, I was hoping to see him today! I wanted to know his thoughts on the new Crimson Riot documentary, he’s the only guy I know who keeps up with all types of hero stuff!” Kirishima sulked as he clenched his fist. Right, that was the video he and Izuku had watched (correction: Izuku watched, Katsuki fell asleep) the night he got quirked. Looks like they’d never finished it.
They rounded the corner to Katsuki’s apartment complex. “Well, anyways, I think it’s super manly you’re making him take a backseat. In high school Midoriya would’ve broken both his arms and still tried to fight a villain. Glad you’re grounding him dude.”
Katsuki walked up to the front entrance, “Yeah well, someone has to make sure he doesn’t die. See ya, Ei.”
Kirishima smiled and waved as Katsuki flashed his keycard and opened the doors, “Night dude! Hope Midoriya gets better soon!”
Katsuki shut the door behind him with a smile, all his friends were supportive of them. In fact, they had anticipated their relationship well before going pro.
Katsuki took the elevator to their high-rise apartment. It had a balcony that oversaw a good deal of the city, and wasn’t bad in price either. It provided tight security for heroes and a close distance to their agency. Katsuki scanned his keycard again at the door and pushed his way inside, surprised to see the entire apartment dark.
“Deku? I’m home.” He shuffled off his shoes at the entrance and said into the empty living room, “Brought your favorite takeout too.”
Katsuki shouldered off his jacket, walked into the kitchen and placed down the food. With still no response he padded to their bedroom, hoping Deku was just asleep. He pushed open the door slowly, with the only light being the lamp on their nightstand. He lowered his voice while peeking in.
“Izuku? You awake? I—”
Izuku was very much not awake, sound asleep, and he was very much still naked. The nerd was passed out on the bed, seemingly slept away most of the day, with his hair still messy from this morning, arms splayed out beside his head, and legs still spread, with—with—
A butt plug in his ass.
It was hardly noticeable in the dim room. Katsuki saw it only because Izuku’s legs were so spread, and a large black object was gaping out. Besides that, Katsuki spotted dried cum on Izuku’s stomach, way more than from this morning. His eyes glanced across the bed once more, and saw a dildo near Izuku’s feet. It was black and orange.
His dick twitched in excitement. Suddenly he wasn’t so tired anymore.
Katsuki quietly stepped into the room, walking over to Izuku, who had his head turned to the side, drooling on the pillow. He still had his pajama shirt on, hiked up to his nipples. He looked so tired and pretty. Katsuki’s pretty fucking princess.
The takeout could wait, Katsuki’s real dinner was right here, waiting for him all day.
Katsuki climbed on top of Izuku, straddling his legs, and took a good look at his husband. His hair was matted and messy, a mix of bedhead and sex rumpled curls. Katsuki brought up a thumb to wipe off some of the drool from Deku’s stupid face, and let his eyes wander down farther.
He started thumbing one of Deku’s nipples, playing with it before pinching harder. Deku scrunched up his face slightly in his sleep and tossed his head to the other side before settling down again.
He started pinching and flicking both of his nipples, which were turning redder by the second, each time he did Deku whimpered lowly, making desperate little sounds and bucking his hips up unconsciously, sliding against Katsuki’s own clothed dick. Fuck, he was starting to get hard. His pants started to tent up.
With one hand still on his chest, Katsuki used the other hand to venture down slowly to Izuku’s lower body, tracing over the hard muscle and scar tissue. He loved this part about Izuku, the grit and determination he needed to acquire the body muscle mass he did, was just proof of how hard he worked. Katsuki slid his hand down further, running his hand across Izuku’s freckled thighs. This was his favorite fucking part, these thighs could crush heads if the user wanted to, and Katsuki got to hold them on his shoulders. They were muscular and pretty, and so biteable.
He circled across Izuku’s nipple again, causing another quiet whimper. He used his other hand to trace around his hole, where the plug was stretching him out wide. At the base of the plug, there was his signature orange X running across, making it notably a Dynamight adult toy.
Katsuki remembered back to when they received that fuckass package from the “toy” company. Izuku had been so excited to receive custom made hero merch, and well, it was hero merch, just not dolls and figurines.
Maybe this was a little different. It was definitely the quirk’s fault, making Izuku so sensitive like this, and resorting to fucking himself stupid with a dildo and keeping a plug in his ass until Katsuki got home, and the toys were in his colors.
A disgusting rush of possessiveness came through him, Izuku was thinking of him when he pleasured himself.
“Mmf…Kacchan? Is that you?” Izuku said scratchily. His eyes blinked slowly, it seemed like he finally woke up. Katsuki pinched harder, “What are you— Ahh—nnghh…!”
Katsuki bent and latched onto his nipple, causing Izuku to jolt and moan obscenely. He flicked his tongue over the bud repeatedly, and faster as Izuku finally regained consciousness and realized what he was doing. He continued lapping it for a few more seconds before biting the area, and letting go with a pop. He leaned back smiling to see a bruise already forming.
“Didn’t know you missed me that much today.” Izuku looked embarrassed, red. Katsuki’s eyes softened, “How you feeling?”
Katsuki put a hand across Izuku’s cheek, caressing it and running a finger across the scar under his eye.
“Good. Slept most of the day, missed you.” Izuku got out, his voice was noticeably dry, probably from cumming too much earlier. Speaking of which—
“You make yourself feel good today? Couldn’t wait for Kacchan?” He leaned forward into Izuku’s space.
“N-no…I couldn’t…” Izuku blocked his face with his arms, and then cleared his throat, “I think this quirk makes it so I need penetration to feel good for a bit. I came twice and still didn’t want to stop…so I had to use, uhm, other things..”
Katsuki throbbed at that, only he could make Izuku feel that good. Some lousy fake cock wouldn’t be enough for his husband, “Bet you wished that dildo was me, fucking you instead, huh?”
The closest hand to Izuku’s ass gripped the base of the plug, feeling the rubbery texture. “Prepared yourself for me too.”
In one motion, he pulled out the plug, leaving Izuku’s ass empty, clenching around nothing but air. He yelped at the sudden movement, and grasped his hands on the bedsheets. Katsuki settled both his hands on Izuku’s knees and sat back on his own to admire the view.
Deku oozed sex appeal, hot, flushed, and ready for him to use. His hole was gaping, red and raw. His feet trembled as Katsuki pushed him wider. The tip of his cock was bright red, too, lacking severe attention. He’d get on that immediately.
Katsuki lowered his head, licking up the shaft once before taking Izuku whole in his mouth. The younger hero kicked up his legs in reaction, trembling like crazy as Katsuki moved up and down again, hollowing his cheeks to wrap and suck his cock.
Izuku moaned and sobbed into the air. He was sensitive in all places, clutching the pillow behind his head as Katsuki bobbed up and down, swallowing him whole. Katsuki looked up to see Izuku clawing and crying messily, feet still in the air shaking. He shoved himself all the way down, nuzzling his nose to Izuku’s stomach, feeling his cock tickle the back of his throat, before pulling back again and looking up to find Izuku a shaking puddle.
He smiled around Izuku’s length and lapped his tongue across one more time before tracing his teeth lightly across.
“Ah…hah—K-Kacchan, I’m—!”
Izuku came hard, curling his toes in the air. Katsuki doubled down and swallowed most of it, he let some dribble from his mouth as he pulled off of Izuku, fully intending to make an erotic scene. Katsuki’s deep red eyes stared into Izuku’s wet, green ones.
He pulled off as Izuku’s thighs settled on the bed and trembled from overstimulation. He took his shirt and threw it somewhere across the room, he’d wash it later. Right now, he’d fuck Deku until he couldn’t walk. He needed penetration to feel comfortable? Not a fucking problem.
He needed to grab lube first, though. As eager as he was yesterday, he realized fucking with spit wasn’t the safest, and if he’s going longer today, he would make sure it felt good. He leaned down to Izuku’s ear, still catching his breath, “Ass up for me baby, I’ll be right back. Be good.”
Izuku whined but didn’t say anything. Without another word, Katsuki got off him and stalked his way to their walk-in closet, rummaging through a drawer until he found a bottle. He thought about other toys that they may have, all joke gifts from their friends as they first announced they were a couple. Maybe they’d actually be put to good use now.
Katsuki sifted around a little more before finding the remote controlled vibrator Raccoon Eyes had given to them when they first started dating. “It’s fun to use on the go, ya know?” Yeah fucking right.
He grabbed the lube and rushed back to their bedroom to see exactly what he wanted. Izuku tucked himself into a downwards doggy position with his shoulders hiked up to his ears, elevating his ass up and still fucking gaping. He was still flushed in the face, dried tears on his cheeks and pressed into a pillow, presenting himself to Katsuki.
He could come right now.
Instead he settled himself on the bed, the mattress dipping from his weight. He took a moment to take the sight in, he wanted to admire first.
“Y’look so good…fuck,” Katsuki slapped and grabbed Izuku’s hips, pulling them towards his clothed dick and arching his back more, “Feel that Deku? You make me like this. Only you.” He bent over Izuku’s shoulder to whisper into his ear. He nipped the bottom of his lobe hard.
Izuku whined into the pillow and pushed his hips back into Katsuki’s crotch area, feeling the hardness poke through. Katsuki smirked and popped open the lube cap, pouring a bunch in. Izuku shuddered at the cold feeling as the excessive amount started to drip down from his legs onto the sheets.
Katsuki pulled down his sweatpants and covered himself in a generous amount as well, his cock was already red hard. He lined himself up with Izuku’s entrance and bottomed out in one go. Both men moaned, Katsuki himself about to cum. His hands settled on Izuku’s hips, needing a minute to collect himself before pulling out and slamming back in again.
He started fucking rapidly into Izuku, loving how beautifully his back curved and arched downwards to a cute, moaning face. From this angle, Katsuki saw all the freckles on Izuku’s back, littered like constellations, flushed and sweating.
Izuku buried his head into the pillow. He knew he could be loud sometimes, but as Katsuki hit his sweet spot with every thrust he had to mute himself somehow. He muffled himself into the bed as much as possible, grappling onto the sheets.
Katsuki, though, was having none of it.
One of his favorite parts about sex was being able to hear Izuku’s sweet sounds. For someone who loved to yap so much about anything and everything, he was able to reduce the nerd into a stammering, moaning mess. When he wasn’t hearing nearly as much of his voice as he wanted to, Katsuki pulled out for a split second. Izuku, confused by the sudden pullout, clenched around nothing and felt the cold seep in.
He was then grabbed by the arms and shoulders and flipped over onto his back. His entire body bounced on the bed roughly, still slightly dazed by the sudden change. His confusion didn’t last for long, however, when Katsuki sheathed himself back in.
His back kept slamming against the bed with each thrust from Katsuki, fucking him so deep he felt like he could taste it. It was so much, too much—each time Izuku thought he couldn’t take it anymore, his own body proved him wrong as his hole kept greedily swallowing Katsuki’s dick.
“Ka–kacchan,” he tried to stutter out between the vicious pace Katsuki set. Drool and tears mixed together on his face; he could taste it with the cum in his mouth.
“Come on baby, just a bit more,” Katsuki urged him on, emphasizing his words with each rough thrust to his prostate. Every part of him was so sensitive that pain and pleasure mixed together; his body writhed under Katsuki as he couldn’t decide whether to run away from the feeling or chase it down.
A loud, embarrassing whine escaped him; Izuku tried to cover his mouth with his hands, but Katsuki noticed and instantly pulled back both his arms.
“Don’t hide it, ‘Zuku. I wanna hear your cute sounds.”
Katsuki continued fucking him deep, grunting everytime he hit Izuku’s prostate. With his hands immobilized by Katsuki, Izuku was unable to cover his mouth and let out high pitched whimpers and moans. His breath built up with each time his body shifted up and down on the bed with the aggressive thrusts. Izuku looked down, and saw how viciously Katsuki was pistoning his hips in and out, determined to not cum just yet. The blonde himself was sweaty, hair sticking up in places that made him unfairly more attractive.
Izuku mindlessly let his eyes wander over his husband’s body, the pale skin with starburst scars, wide shoulders with heavy muscle that trimmed down to a slimmed waist that fit snugly into his hero costume, and rock hard abs that would make anyone fall in love just by looking, a happy trail leading down to the cock fucking him relentlessly.
Katsuki’s pace started to falter, sloppily plunging in and out of Izuku’s hole and losing grip on his arms. Izuku could feel it too, the pleasure starting to overtake him and building up his climax. Katsuki bent to bear hug him, letting go of his arms and wrapping around Izuku’s entire upper torso, effectively trapping his arms anyways. He leaned forward to knock their foreheads together, Katsuki shutting his eyes and clenching his teeth, trying his hardest not to cum, while Izuku tossed his head to the side, face covered in dried tears, with more accumulating. His eyes were shut just as hard too, and moaned loudly at every thrust.
Katsuki, knowing he was at his limit, thrusted vigorously, making sure to hit Izuku’s prostate each time. Each shout and groan next to his ear invigorated Katsuki to hit deeper the next time.
“Fuck..fuck! Fuck, Izuku, I’m—”
“K-Ka—hah—chan!”
They both came at the same time, Katsuki cumming deep inside Izuku, painting his walls white again. Izuku came over his and Katsuki’s stomachs, the liquid seeping onto their bedspread as well. They both panted, with Izuku’s breath coming at more hoarse.
Katsuki shallowly fucked in and out, drawing out all the liquid before slipping out. He unceremoniously collapsed onto him.
Izuku looked up at the dark ceiling, eyes weary again, but smiled happily, “You playing with me in my sleep too?” He thought about this morning when he rode Katsuki’s stomach.
“Don’t get smart with me ‘Zuku, that’s the perviest thing I’ve ever seen you do.”
Izuku laughed and Katsuki felt the reverberations in his chest as he laid on top of him. He snuggled into Izuku’s neck.
“So…you’re saying you have to get fucked to get some relief?” He had a hint of joy in his voice.
“Uhm..I guess so. That’s how it felt really. I’m not sure how this quirk works… If I don’t come from that then everything starts to get really itchy and uncomfortable.”
“If you ever need to get off and I’m here, just do it, okay? I don’t care if I’m cooking or sleeping. Anything, anytime you want, Deku.” He looked at the younger, who was red in the face again from his words.
“Y-yeah…okay. Y-you can…uh.. Do the same to me.”
“Oh really now?” Katsuki slurred his voice slyly, “Anytime? Anything?”
Izuku stammered, suddenly acting like a shy maiden, “I-I mean it’s fair, right? You help me and I-I’ll help you!”
Katsuki frowned, he grabbed Izuku’s chin to turn and face towards him.
“Hey, I’m not doing this because of the quirk, okay? I’m doing it ‘cuz I love you. And yeah, it is letting us fuck and we haven’t in a while, which is great. But if you wanna fuck, I want to as well. Anything you need, I need. Whatever you want, I’ll do.” Katsuki said sternly, Izuku’s eyes widened slightly. He smiled as Katsuki’s hand settled on his cheek again.
“I love you too Kacchan, it’s all the same for me.” He kissed the tip of Katsuki’s nose, who flushed. Izuku giggled before yelping at the sudden slap to his ass again as Katsuki spoke up.
“Yeah yeah. Besides, I’ll never get tired of this ass.”
“Kacchan!”
“Hmph,” Katsuki said with a shit eating grin on his face, before softening again, “Rest a little ‘kay? Then we can eat dinner.”
“Mmkay Kacchan.”
--
“Monjayaki! Is this from the restaurant downtown?” Izuku beamed as Katsuki held up a plate for him.
“Yup, stopped by on my way after work with Shitty Hair. He says hi by the way.”
After a short 30 minute power nap, Katsuki helped wipe down Izuku with a wet towel and put boxers on since, who would’ve guessed, he could not walk one step without falling over. Katsuki bridal carried him to the living room instead, setting him down on the sofa while he heated up the food. He sat down on the sofa next to Deku, handing him a plate and digging in.
“Don’t forget to drink water too, not enough hydration and your next orgasm is gonna come out dry.”
Izuku gasped jokingly and shoved Katsuki’s shoulder lightly. He whined with food in his mouth, “Kacchannnn! We’re eating!”
Katsuki chuckled and took a bite of the yakisoba, Izuku was practically inhaling his, seeing that he hadn’t eaten anything all day.
“You think this’ll be gone by tomorrow? I have class.”
Katsuki set down his plate, “Didn’t get a call back from the lady yet, so I’m not sure. Wouldn’t risk it though.”
“But it’s late and I can’t just bail on my students like that! I only see them three times a week now.” Izuku pouted, “And plus I don’t think Mr. Aizawa would be very happy with me.”
“He’d be happy that you didn’t try to teach while being out of commission. Just stay at home, there’s no way this shitty quirk lasts more than a week, tops.”
“There was a lesson I really wanted to do tomorrow…And I wanted to see the kids’ new moves too!” Izuku paused and bit down on the savory pancake, “Kota said they were training all week perfecting final moves!”
“Ha! That brat couldn’t pull off a water blast to save his life, c’mon now Deku. Imagine how bad it would look if you suddenly got really horny on campus.”
“But I only teach in the mornings! If we do it early in the morning, right before I go, then I could last until lunch and leave!”
“Oh?” Katsuki smirked, “You wanna get dicked down in the morning? Right before class? Didn’t know Deku-Sensei was so unchaste.”
Izuku leaned forward into Katsuki’s space, “Yeah, says the one who came home first thing to have sex!”
“From you who got off twice as soon as I left?!” “At least I got hit by a quirk! Why are you so horny?”
“I’m about to leave you with blue balls next time, Deku.”
Izuku gasped in faux surprise and dramatically fell on Katsuki’s chest, “Noooo! Kacchan would never! Kacchan’d do anything for me.”
They looked at each other for a few seconds and started laughing. Katsuki hooked his arm around Izuku’s neck, pulled back his curls and kissed his forehead.
“Damn right I would. But you’re still not going. It’s risky.”
“Pleasseeeee..?” Deku whined, flashing the best puppy dog eyes he could.
“No.”
“But—” “No,” Katsuki said sternly, furrowing his brow, “It’s a no, Deku. Sit your ass at home. I’ll call Aizawa tomorrow about it.”
Izuku grunted a noise of disappointment and pouted into Katsuki’s chest. It was hard to win an argument between them. Katsuki had seemingly dropped it already, opting to run his hands through Izuku’s sweaty curls. He had a calm, almost serene expression on his face. His eyes settled to focus on untangling the mats in Izuku’s hair, and he couldn’t help but smile anyways.
Even though he had slept away most of the day, he felt tired again. His eyelids drooped as he relaxed his body onto Kacchan, lulled by the long fingers playing with his hair.
--
Izuku woke up sore. It was no surprise from yesterday. He could barely walk to the living room by himself, needing to have Kacchan carry him instead. He laughed the whole way, as if the blonde wasn’t the one who had done this to him. Speaking of—Izuku woke up in bed, which means Kacchan carried him to sleep yesterday after dozing off on the couch. He had also successfully managed to get Izuku to drink a liter of water, use the bathroom, and rinse off after dinner. And now, Kacchan was hugging him from behind, nose nuzzled into Izuku’s nape and fast asleep.
Izuku pawed under his pillow for his phone, opening his lock screen. 7:30 AM. He had 30 minutes to sneak out before the first bell rang. He experimentally tugged himself towards the edge of the bed, only to find Kacchan’s arms wrapped around his torso. And then a sudden heat crept up his body again.
Crap, I almost forgot.
Izuku panicked, already feeling the pool of heat settling in his lower belly area. As much as he didn’t want to admit Katsuki was right, he absolutely could not go onto campus like this. But he also didn’t want to miss his planned lecture as well. The staff were expecting him today, not yet notified of his “circumstances.” He just needed to make it until lunch time and then can dip the rest of the day.
A light snore to the right of him.
And get out without waking Kacchan up.
Here goes nothing.
Izuku carefully removed the hands grappling his torso, although with some tugback from the still sleeping blonde. Usually, it didn’t take a lot to wake Katsuki, but Izuku was just banking on him being tired from his shift and the sex they had yesterday not to hear him.
He had snuck out of bed several times before without waking Kacchan up, but he knew for a fact that riding him would definitely wake him up. Izuku would have to opt for an option that was less likely to get him caught.
Once slipping out of the larger man’s arms, Izuku quietly replaced his spot with a large stuffed doll of himself (a cute squishmallow from Ochako actually). Backing away slowly, Izuku also took the black and orange dildo from last night, discarded near the edge of the bed. He looked back once at Katsuki, still lightly snoring into the new pillow in his space, brow slightly scrunched up.
Izuku padded out of the room quietly into the bathroom, and flicked on the light switch. The bright light burns into Izuku’s eyes, temporarily blinding him before readjusting. He had secretly set up his teaching clothes underneath the towels on a rack, unbeknownst to Katsuki.
Their bathroom was quite spacious, as they would often take showers and baths together. First rinse was in the shower, and then the bath was for soaking in and untensing muscles after a long day. The bath was placed in a tucked in part of the bathroom, with a high towel rack on one side of the wall and a mirror on the other side. The sink held another mirror atop of it. It had a larger counter surrounding it, where they both placed their toiletries (Katsuki’s 10 step skincare routine and Izuku’s toothbrush).
Izuku lowered the lighting of the room slightly—a fun feature Katsuki added when they felt like staying in the bath for longer but not wanting to brace the fluorescent lights.
He was still naked below the waist, and could feel the ickiness of the dried cum still inside him. Well, time for round 5.
Izuku lowered himself into the bathtub, skin hitting the cold porcelain as he settled with his back against one end and lifted his legs up on the edges. His hole was exposed to the cold morning air. He quickly slicked up two fingers in spit and prodded his entrance before shoving himself past the ring of muscle.
“Nngh..Fuck..” He kept his voice to a whisper, he absolutely could not wake Katsuki up right now.
He hauled up one of his legs onto the lip of the tub to gain better access. The cold material sent a shiver up his spine. After just a few silent minutes of constant pumping in and out of himself, Izuku pulled out his fingers and lined up the large black toy with his entrance.
As he slid it in gently, his head tipped back and bumped against the porcelain, eyes screwing shut and mouth silently gaping open as he pushed it deeper inside himself. A cold sweat built up on his neck as he bottomed out, the base of the dildo making contact with his skin.
“Nnhg..ah…ah..”
The bathroom was completely silent, save for the lewd squelching of Izuku fucking himself on the toy. He shut his eyes and thought of blonde spikes above him, manhandling him down in the bath, a warm palm on his throat, and a gravely morning voice speaking to him. Kacchan could be mean when they had sex, it wasn’t uncommon. But he noticed the blonde did like to be gentler overall, not that Izuku would ever complain—but he had his own sick fantasies he dreamed about sometimes.
He bit his lip to make no noise. The warmed rubber was tracing along his walls, dipping into every crevice inside him. At this point he was completely back against the floor of the rub, legs in the air trembling and shaking. If Kacchan walked in right now, he’d see tufts of green hair and his legs jumping up and down.
He then repositioned himself back so he was kneeling and readjusted the cockhead to stick to the floor of the tub. He lined himself up with it again and sank down with one go.
He slowly opened his eyes as he continued the motions, suddenly meeting himself in the mirror on the opposite side of the towel rack. Green curls bounced up and down, a dazed look in his eyes he could barely make out through the steady buildup of tears and arousal. He looked debauched. He liked it.
Izuku silently moaned as his thighs moved up and down, starting to get tired and sore from the cramped space. He sank down one final time, spearing himself, and releasing all over the inside of the tub.
“Good boy.”
“You look so pretty from back here Deku.”
“Reverse cowgirl, huh? You ride me so damn well, baby.”
He could almost feel the sharp red gaze from behind his back, Kacchan staring at his back heaving as he came. He could almost feel those long, slender fingers tracing down his back, making sure to hit every one of his freckles. He could almost feel the prodding and groping of his ass as Kacchan got a look inside where he came, making sure to thumb open his entrance to let some white drip down his legs.
He gripped the edges and bent forward, dildo still inside him, as his cock twitched once and again before he started to resettle into his senses. Izuku finally allowed himself some noise, panting into the empty, now warm room. He let himself have 2 or 3 more minutes of peace before cleaning himself off, readjusting his outfit, and freshening up. It seemed like the heat in his stomach was gone for now, and he could finally move on with his day. He had to get to UA fast.
With some dirty towels and the used toy in hand, Izuku carefully opened the door back to their bedroom where he found Kacchan still peacefully sleeping, seemingly not hearing a sound. Izuku smiled watching Katsuki sleep like a kitten: gentle, soft snores, and cheek adorably squished up against their pillows.
Izuku quickly threw the towels into the hamper, and stashed away the dildo under their bed. He kissed Kacchan on the head before grabbing his case and heading to UA.
