Hero Duties Come First

Summary:

“Ah! Kacchan, I’m close. Oh my gosh, Kacchan, I’m so close—”
Their phone beeps.
They both freeze.
Izuku gaps. “Villains!”

Hero duties always come first. Although, getting a call of duty in the middle of a mindblowing sex apparently makes Izuku prone to making stupid mistakes.

Or: that one time Pro-Hero Deku accidentally wears a sex toy to a rescue mission.

Notes:

I previously titled this fic as “At the End of the Day” but decided to change it :)

Work Text:

Part of being a pro-hero is gaining an extraordinary ability to manage time.

A few years ago Izuku might have dismissed time management courses as something only suited for businesspeople. However, the longer he’s involved in this line of work, the more he regrets not taking that class long ago. 

Nowadays getting himself even so much as one day off work has been an increasingly difficult feat. Crimes run rampant in every city, Musutafu included. There’s not a single day goes by without him arresting at least one or two villains.

The collapse of Hero Society that preluded the huge war against All For One three years ago is to be blamed, sure, but there’s no use regretting it now anyway. While the heroes are drowning in their own guilt, criminals are taking their sweet time to start a chaos everywhere. Izuku has adapted into this mindset: less mulling, more pulling.

Taking action is the important part. There would be no results at all if no one’s taking action.

He’s implementing the very same mindset as well regarding his lack of free time. Rather than bemoaning about the lack of days off and holidays he’s getting, he tries to make the most out of the little free time he’s got on his hands instead.

Hence why he is here, in a fancy love hotel in the outskirts of Musutafu, laying on the softest bed, hands tied to the bed frame with a pretty silk ribbon, and ass plugged with a beautiful glass buttplug that was Katsuki’s Valentine’s Day present for him last year.

“Ah! Ah! K-Kacchan…”

Izuku can be loud here. Izuku can be shameless here. 

He personally knows the owner of this establishment, and he can attest to the quality of service this hotel provides; their security system is top notch and customer’s privacy is definitely guaranteed. Moreover, he has been a frequent guest to this hotel. This particular love hotel is one of the best in the city. Located just a couple kilometers away from their offices, this place is his and Katsuki’s little heaven in the midst of their busy day.

“Open up those pretty legs,” Katsuki says, joining him on the bed after he slides off his pants, “Gonna make you cum ‘till you beg me to stop, nerd. Gonna make you cry those fat tears for me. Gonna bring you to heaven and back.”

Katsuki’s lustful grin makes Izuku’s heart thump inside his chest. His ass clenches, his pussy throbs and drips so wet that he can smell the musky scent. He looks up at Katsuki with heavy-lidded eyes. “Kacchan, please…”

“Please what? Spank you again? Want me to play with your cute ass? Or eat out your pussy?”

“Everything!” Izuku sobs. 

He squirms a bit when Katsuki spreads his legs even more, baring all of Izuku for him to see. Izuku eventually yields, subjecting himself to Katsuki’s gentle touches and sighing in pleasure when his pussy is given more attention.

Yes, this is what he’s doing, making the most of his lunch break doing not so innocent things with his gorgeous boyfriend.

The public can never know about this, for sure.

“Gonna eat you up now, pretty nerd.”

That’s all the warning Izuku gets before Katsuki goes down on him, attacking him with his skilled tongue until he can’t help but tilt his hips up to get more.

“Kacchan! Kacchan!”

Katsuki’s hands get to work just as hard as his mouth. He rakes his fingers along the inner side of Izuku’s thighs, occasionally slapping his butts and digging his nails.

Izuku is writhing in pleasure, moaning, “Ah! Kacchan, I’m close. Oh my gosh, Kacchan, I’m so close—” when their phones beep at the same time.

They both freeze.

Izuku gaps. “Villains!”

It doesn’t matter even if his boyfriend is tongue-deep inside him, or he is literally one breath away from a nice and fulfilling orgasm. A call of duty is a call of duty. Their responsibility as a pro-hero comes first.

Having that in mind, Izuku jerks violently, accidentally hitting Katsuki's face with his knee in his haste to get up. He uses One For All to free his wrists and briefly mourns on how the pretty ribbon is now ruined. Though, he doesn't have the luxury to think much about it.

“Do we really have to go?” Katsuki groans. “There should be other heroes nearby at this hour. Where’s all those shitty extras now?!”

Izuku smiles sourly. Truth be told, he is just as reluctant to go as his partner is. “Well, you know the drills, Kacchan. If the Hero Network is alerting us that means we're the closest pro-hero available to the scene.”

“We are not fucking available.

Despite all his grumblings, Great Explosion Murder God Dynamight is the one who's done dressed up first. Izuku is not far behind his partner, zipping up his Deku suit and double-checking his gauntlets before readying himself to make a dash.

“Gonna take the shortcut?” Katsuki asks, already opening the windows without waiting for the answer.

Izuku answers him anyway, nodding curtly. “Yep.”

Katsuki blasts himself through the window without glancing back, knowing for sure that Izuku would follow closely behind. Because yes, it might be a twenty-story building and they are renting the room on the fifteenth floor, but Izuku has enough mastery of his floating quirk by now to make a quick dash from the rooftop of skyscraper buildings.

“Hey. You checked the ping yet?” Katsuki asks distractedly.

No, Izuku hasn't checked it. He even forgot to check his phone at all before dashing out, not even the GPS map—sue him, having to jump into a rescue mission after being denied orgasm was never covered in his training—so yes, he’s only trusting his hero partner here to know where they’re heading.

Again, Katsuki doesn't bother to wait for his answer before continuing, “They say it’s some shitty bastards messing with a building in construction. So, you get the civilians away and I’ll catch those bastards. Sounds like a plan?”

Izuku huffs a laugh. “What kind of plan is that?”

They arrive at the scene before Katsuki gets a chance to dish out a comeback. They immediately spot a couple people with flashy quirks down below. There’s a small crowd huddled at one corner of the unfinished building, they seem to be shying away from a big baldie with some sort of mutant quirk. Izuku decides to land at that corner, placing himself between the terrified people and the villain, while Katsuki blasts himself towards the pair of twins that’s messing with the construction building two-story above them.

“You’re late, Hero!”

The villain allows himself a mocking cackle that echoes in the walls. Izuku snorts dryly. He might not be number #1 yet, but he’s had his fair amount of experience fighting off villains with power-type quirks.

This guy is an easy cake for him.

Sure enough, not even 5 minutes later, the guy is already slumped on the walls. Izuku hears a police siren sound from afar. Good thing. He and Katsuki won’t have to bother themselves with bodily dragging these villains to the nearest police office then.

“Is everyone okay?” he calls out to the crowd.

A middle-aged lizard man who’s wearing construction worker gears steps up. “I think my friend is still stuck somewhere inside the building. I haven’t seen him anywhere since the villains showed up here. I’ve been trying to call him but my calls don’t go through.”

Izuku frowns, mentally assessing the half-finished building. There isn’t too much damage caused by those villains, so even if there’s someone stuck inside, they should be fine. “Alright. I will go check. Where do you think he is?”

“If I remember correctly, I think he was working on the 13th floor,” says the man.

Another person, a fairly young woman with a ponytail and safety goggles this time, steps up. “I think my twin is stuck inside too. She was working on the electricity flow on the same floor.”

As if it’s a butterfly effect, a few people are starting to voice out their concerns for their other co-workers as well. Izuku quickly collects all the information and briefly assures them about their co-workers’ safety before he begins climbing up the building. It’s not long before he spots someone crouching on the concrete floor. A huge hole appeared on the wall right across from her, no doubt it’s the villain’s mess. She looks a bit terrified.

“It’s alright now, Miss!” Izuku calls out. “I’ll bring you to safety!”

He reaches out with his Black Whip to pull out the young lady. He quickly finds some other people before arriving on the 13th floor, where a group of five or six people are crouching down together.

“Hello! It’s alright—”

Izuku doesn’t get to finish his words. A particularly harsh blow to the concrete wall to his side almost throws him off his balance. The wall crumbles, which in turn reveals a very annoyed Great Explosion Murder God Dynamight who seems to be in a one-on-one fight with a huge woman with fiery red hair. The villain extends her arms, palms open, and—

Is that fire?!

Izuku tries to take several steps back to avoid the burst of flame. But he’s too distracted and ends up tripping on a small rock, landing back on his butt, and jolts violently.

A sharp pleasure shooting up his spine. Which is weird. But not a second later horror and realization suddenly dawn on him: he’s still wearing his sex toy inside.

For God’s sake—

Another harsh blow. The building shakes with its impact. Unfortunately, the vibration goes straight to the toy inside him. Izuku suppresses a needy whine.

He doesn’t understand how the hell he didn't realize it until now. How in the world did he even forget about it in the first place?! Only heavens know.

Izuku tries hard to push away any inappropriate thoughts. Alas, it’s proven difficult when a fat silicone toy pushed so deep inside his ass. The fall that he takes to his butt that not only pushes the plug further up his ass, but also shifts its angle to better hit his sweet spot, is absolutely no help here.

A loud shriek jolts him out of his dilemma. Right. There are civilians to save here.

He does his best to catch everyone with his Black Whip and brings them down to a safe area by the sidewalk, away from the on-going fight between Katsuki and that arson villain.

The building is still on fire, but the police squad arrives alongside the firefighter squad. It doesn’t take them long to squash the fire. By the time Katsuki has that red-head villain pinned down, the fire has already been put out.

“Good job, Heroes,” Detective Takeuchi, who comes along with the police squad, greets them with a salute.

Izuku flashes his smile. Truth be told, he would like to skip the small talk this time, since there’s another urgent matter he has to tend to. Namely his sexual desire and the toy inside him.

From the corner of his eyes, Izuku spots a mob of reporters and journalists making their way towards them. 

Oh, crap.

He quickly grabs Katsuki’s arm as soon as the other lands beside him. “Well, then, Takeuchi-san, we better get going now. There’s still a lot of villains running on the streets and we need to catch them. Of course. Haha. I will email you a copy of the report for this incident. See you later!”

He physically hauls Katsuki, who starts protesting and squirming in his hold, to get away as far as possible. It’s not until he finds a quiet corner in the back alley of a fairly empty street that he feels safe enough to land them both.

“What the hell, Izuku?! What’s the hurry?!”

Katsuki sounds more concerned than annoyed, which actually makes sense, since most of Izuku’s friends tell him that he often acts suspicious whenever he’s hiding injuries.

Izuku swallows thickly, grimacing. He glances around to make sure no one is following them or anything, before pressing himself up against his boyfriend to whisper, “I forgot to take out the plug inside me.”

Katsuki blanches. “What the fuck?!”

“Exactly! I didn’t know it was there! But then I fell on my butt and—” Izuku cuts himself off, gesturing vaguely, face flaming hotly at the thought that he had just rescued villains while having a sex toy plugged inside him.

Katsuki pinches the bridge of his nose. “Of fucking course, you would do something as dumb as that huh, Deku?” He sounds even more exasperated than Izuku is. “So, what do we do now? You’re not really thinking that we could just have sex in the back alley like this, do you? The PR team will totally chew our asses if we get busted here.”

Izuku whines. His pro-hero persona all but evaporates into thin air now. He doesn’t want to think. He just wants to get his nice orgasm already after being denied and feeling like he was edged while doing a mission.

“I don’t know, Kacchan!”

Katsuki clacks his tongue. “Let’s just go back to that hotel.”

“It’s too far!” Izuku complains petulantly.

Katsuki is silent for a minute, staring at him weirdly. Izuku finds his boyfriend is kind of hot when he gets all serious like that. He can’t help the way his front hole throbs under that intense stare.

“Fine,” Katsuki says after a while, “I have an idea.”

That idea, apparently, consists of a very inappropriate usage of one of his quirks.

“Don’t complain,” Katsuki grunts, one hand pumping his cock and the other knuckles-deep inside Izuku. “You’re the one who desperately wants this, idiot.”

Izuku huffs. “I know. You don’t hear me complaining, do you, Kacchan?” 

Not that there’s many things to complain about when he’s too focused on keeping the smoke screen thick enough around them, all the while trembling in pleasure each time Katsuki’s fingers brush against his sweet spot.

Besides, despite his initial reluctance, Izuku finds it thrilling to have sex in the open like this. Not that he would encourage it, but…maybe they could have a repeat sometime in the future.

“Tell me if it hurts,” is Katsuki’s only warning before he starts pushing into Izuku.

Izuku moans at the stretch. He loves it. God, he freaking loves his boyfriend and his fat cock.

Once Katsuki is balls-deep inside him, Izuku heaves himself up to cling on Katsuki’s neck, wrapping his legs around Katsuki’s hips to cling like a koala. Katsuki gets the hint, grabbing a handful of Izuku’s ass to prop him up against the brick wall.

“Shit. Pay attention to your quirk, nerd! Those smokes are thinning out!”

Izuku grits his teeth, gathering his focus once more to keep the smoke screens up around them. He manages to add layers to those smokes, but he still pouts at Katsuki. “You try using your quirk with a dick inside you! Then, you’ll see how hard this is!”

“I said no complaining,” Katsuki growls. He smashes their lips in a rough kiss before Izuku manages to open his mouth wide enough to complain. Izuku moans into the kiss, which only eggs Katsuki more. “We’re doing this because you and your needy pussy can’t fucking wait long enough to find a decent place, so fucking suck it up.

Izuku cries out in pleasure. Katsuki emphasizes his point with a series of hard, unforgiving thrusts, driving his cock home again and again until Izuku is reduced into broken moans and sobs. His quirk control slipping.

Katsuki leans in. His teeth sink in. He begins leaving a series of marks on the sensitive skin of Izuku’s neck, making a trail up his jaw, biting the shell of Izuku’s ear and whispering lowly, “Hang on that control, nerd. Or else.

It’s clearly an empty threat. But hearing the timbre of Katsuki’s rough voice is enough to send Izuku to overdrive. He gasps. He gapes. He clings tighter on Katsuki as his body spasm with awaited orgasm.

Katsuki kisses him deeply as his mind slowly goes down from the high heaven.

“K-Kacchan…” Izuku whispers shakily, still panting, eyes fluttering to keep his gaze on Katsuki’s pretty orbs. “Kacchan, cum in me. Please. Fill me up. I, ah, I want it.” He digs his blunt fingers on Katsuki’s back, whining softly. “Wanna be full of your cum. Kacchan…”

Katsuki captures his lips once again. He murmurs, “Fucking greedy nerd.”

The way Katsuki pounds him is different this time. It’s slower, each drag of his cock more deliberate. Izuku is trembling in his hold, yet Izuku keeps clinging onto him. Katsuki presses their bodies more to close whatever gap is left between them.

When Katsuki finally spills inside him, Izuku momentarily forgets that they’re currently in public.

“Fuck. You’re a mess,” Katsuki mutters, slowly pulling out.

Izuku tips his head back on the moldy brick wall, still high on adrenaline and hormones running through his veins earlier. He doesn’t even notice the streak of cum dripping down his thighs.

“We should do this again sometime,” Izuku says dreamily.

Katsuki stares at him flatly. “We should get out of here before anyone accidentally sees us.”

Izuku gives him a dopey smile. “Carry me?”

“Fucking spoiled.”

Still, Katsuki crouches down to let Izuku climb onto his back. He grumbles all the way back while Izuku snickering behind him.

This is one the best parts that come around with this line of profession he'd chosen, Izuku muses.

Being able to partner-up with the love of his life is definitely one of the best parts.
