****** i don't care who flirts with you ******
by Birdschach, WattStalf
Summary
     ...he says, while caring very much. And then goes for the age old
     setup that gives "in the closet" a new layer.
Notes
     Honestly I'll be the first to say he dialogue is too much. This is
     too much talking to be sexual frustration relieved in a closet, and
     that is all Birdschach's doing. But by the time I realized it was a
     problem I didn't want to cut it so you guys are stuck with this shit.
See the end of the work for more notes
“Hey, Deku! Your tie is totally messed up!” Uraraka says, as Izuku walks into
the classroom. She giggles afterward, amused by how red his face gets.
“I-It is?” he asks, stammering a bit.
“Here, let me help,” she says, bounding up to him to straighten it.
“Thank you,” he says. “I didn't know it was so messed up…”
“Don't worry about it! It's all better now, and it looked kind of cute before!”
“Oh, gee, thanks!” he answers, looking unsure of himself as he does, not able
to help himself from glancing in Katsuki’s direction. As expected, the boy is
glowering, but making it a point to look the other way.
It’s not like Katsuki cares or anything. They’re not together, so what does it
matter if someone flirts with Izuku? It’s annoying as hell, yeah, but he
doesn’t actually care. Besides, whatever the fuck she's doing barely counts as
flirting anyway, and she calls little things he does cute all the time, so it's
not that different than usual. Unless she's always flirting, which is possible,
but he still doesn't give a fuck. There's nothing going on between him and
Deku, and that's that.
He doesn't care about it one bit, which is what he keeps reminding himself as
their morning classes pass by. The closer to lunch he gets, the more annoyed he
gets, glaring daggers at Izuku. As if he wants to see the other boy getting all
happy like that first thing in the morning! Even though he knows he doesn't
care, he still can't wait for lunch, shifting in his seat impatiently.
When the bell does ring, and the class is free for lunch, Katsuki has an
entirely different goal in mind. He singles out that stupid, messy hair and
comes up behind Izuku, placing a hand on his shoulder. It would be nothing more
than a friendly gesture, were it not for the way he squeezes him, his fingers
digging into Izuku.
“K-Kacchan?!” Izuku squeaks, glancing back at his classmate.
“Quiet, nerd,” he says, “We need to talk!”
“Okay, you want to sit together at lunch or something?”
“What the fuck? No. This isn’t something that needs a fucking audience, and why
the hell would we be seen together anyway?”
“I just thought… well, maybe it’d be the next step?”
“Next step to what?! I’ve told you so many times to cut out this weird shit, I
think you’re a lost cause. Fuck, let’s just go find a supply closet or
something.”
“What for?” he asks, his face naive. However, it only takes a second for
realization to dawn on him. “Oh, you mean you...right now?”
“Why? Is that a fucking problem?”
“Well, no, it's just...that's kind of bold, even for you,” he says, blushing.
“I mean, you just said you didn't want to be seen with me, so for you to-”
“Would you shut up already? Either come with me or don't, I don't care either
way,” Katsuki snaps.
“I don’t think I have much of a choice, with that grip on my shoulder…” Izuku
says, and it’s true. Despite his dismissive attitude, Katsuki still has an iron
grip on Izuku. “I’d go either way, though.”
“Oh, really? So you’re not moving on to round face?”
“What? What do you mean?”
“Nothing, damn it. Why do you read so much into everything I say? Let’s just
go, and fucking get this over with,” he says, and begins walking them away from
the crowds, to a secluded area within the school.
“But… you’re the one who wanted to go. You’re not rushing now, are you?”
“You don’t know what I want, fucking nerd! Just shut up, Deku, we’re almost
there.”
“You're talking kind of loud yourself,” he mumbles, but there is no one around
to see them as they finally duck into a closet. There's just enough space, but
only barely enough lighting. “Kacchan, are you mad about something?”
“What? Why the fuck would I be mad?” he asks, already unfastening his belt. “I
just felt like this, alright?”
“If you say so. I mean, now that we’re alone, I'm really not opposed…”
“Oh, gee, thanks,” he says in a mocking tone. Immediately, he regrets even
bringing it up, since he doesn’t care about it in the first place, and Izuku
gives him a confused stare.
“Kacchan, was it this morning?” he asks.
“What about this morning?”
“Now that I think about it, you did seem kind of ticked off about something.
Are you mad because I let Uraraka help me with my tie?”
He misses the mark, but not by much, and now that he mentions it, watching her
get so close was pretty annoying. “No, what do I care? The whole class could
have an obvious as fuck crush on you, and I wouldn’t care.”
“C-crush?! Come on, Kacchan, it’s not like that…”
“Who cares if it is or isn’t? I already said I don’t care,” he replies.
“It’s okay if you do. I mean, we are kind of-”
“We aren’t kind of anything,” he interrupts. “Would you just get on with it
before I lose my fucking boner?”
“Oh, okay!” Izuku says, and even if the faint lighting, it’s clear that he’s
blushing. “But, um, we don’t have anything, so it might hurt a little at
first.”
“As if I fucking care. Maybe you might be sensitive, but I’ll be just fine.”
With that, he bends over, and in the cramped space, he’s left with his face
nearly pressed against the wall. While he drops his own pants, he hears the
rustle of fabric that lets him know Izuku is doing the same thing.
Izuku puts two fingers in his mouth, sucking on them for a moment, making sure
they are coated in his spit. Once they’re wet, he pushes his fingertip against
Katsuki.
“Ready, Kacchan?” he asks.
“I’ve been ready, Deku.”
He pushes in, then, his finger working its way into Katsuki. The blonde
whimpers, it’s a tighter fit without lube, but Izuku is gentle. Still, it is
hard for Katsuki to keep quiet as Izuku hooks his finger inside of him,
especially when he works a second finger inside.
Katsuki hates how damn tedious this part is, even if it is necessary. But as
Izuku begins scissoring his fingers, stretching Katsuki out, it gets more
difficult for him to worry about that.
“Don’t you think that’s enough, Deku?” Katsuki asks, finally, his way of saying
he’s ready to move on.
“If you do, Kacchan!” Izuku says, pulling his fingers out. He pulls himself
out, then, and spits into his hand. He works his saliva onto his cock, working
quickly. He can tell how badly Katsuki wants this, and can’t deny his own
desire.
“Would you quit talking? Someone’s gonna hear us, don't you know how to be su-
ahh!” His sentence is cut short as Izuku pushes inside of him, not so suddenly
that it hurts, but suddenly enough to stun him.
“Right, sorry,” Izuku whispers. “Does that hurt?”
“I said stop talking,” he mutters, hoping his voice doesn't betray just how
badly he needed this. No matter who may look at Deku or call him cute, or try
to flirt with him, he’s the only one that the other boy is fucking. Izuku is
his, and if he weren't so stubborn he might admit the ownership went both ways.
At least, he sure as hell never looks at anyone else.
As Izuku continues thrusting into him, however, it gets harder and harder to
focus on anything but the fullness he feels. It's such a relief with how
jealous Katsuki had grown, and it takes all he's got to keep quiet as Izuku
fucks him.
In spite of himself, a few quiet moans slip out, until Izuku reaches forward,
pushing his fingers into Katsuki's mouth. It's enough to muffle the boy’s
cries, though of course there's a part of him that worries it's the very
fingers Izuku used to get him ready.
Izuku moans softly, hardly able to contain his excitement. Katsuki always finds
that damn enthusiasm so annoyingly cute. Where does he get off being so fucking
excited? And when they're doing something so risky, at that.
He wants to snap and scold him, but if he were the one to talk, then he'd just
invite scolding from Izuku, so he bites his lip instead. Soon enough, however,
it's not just his sharp words he's fighting to hold back, and when a moan that
matches Izuku’s escapes, he grits his teeth hard in retaliation. It's not like
he's going to be able to take much more at this rate, and he knows it, ready to
be done with it as the risk of being caught keeps occurring to him.
And yet, as ready as he is to be done, he clings, he holds back. Like hell he's
going to finish before Izuku! But each thrust pushes him closer and closer to
his limit. As a desperate gambit, he begins working his hips from side to side.
It isn't much, considering the confined space, but it's enough to drive Izuku
crazy.
With the added motion, he can only last a few more thrusts. He gasps, as he
comes, his seed spilling into Katsuki. The heat rushing into him, coupled with
the sound of Izuku’s climax, finally proves too much for Katsuki, pushing him
past his own limit. Like a fucking idiot, his judgement was too clouded by his
overwhelming need to prove that Deku was his for him to consider cleanup, and
he's lucky he doesn't get anything on his uniform. Still, that doesn't help
with the mess left along the wall, and on the floor. Letting out a heavy sigh,
he looks back over his shoulder with a scowl, and Izuku hurriedly pulls out of
him.
A little bit of searching turns up a roll of paper towels, which does the trick
well enough to hide evidence, and then he gets back in his pants and sticks his
head out the door. Without waiting for Izuku, he goes out, upon seeing that
there isn't anyone else around, and sits in the classroom until lunch is over.
He doesn't know where Izuku goes in the meantime, but when he returns, he's
with his friends, which just pisses Katsuki off all over again. The fact that
he realizes he's totally starving after skipping lunch does not help matters.
He's going to have to get Izuku by himself again after school, and he's going
to have to figure out what to do to stop getting so worked up over seeing him
with other people. If only he could bring himself to make things official and
public, but for the time being, he is still too stubborn to do that.
