Summary
     You still doing okay, Kacchan?
Katsuki doesn’t want to think of himself as giving. If anything, he wants to
think of himself as a tease, or as distant, detached, uninterested. Certainly
not giving, and  certainly  not  needy .  That  sort of thing should fall to
Izuku, naturally, while he keeps his distance, and plays it cool, and never
lets on just how hard he’s falling or how much he needs this little
arrangement.
And yet he’s the one who goes to pieces, he’s the one always offering himself
up, while Izuku teases him with such an innocent smile that he almost falls for
it every time, but he knows better. He knows all too well by now that Izuku is
a bigger tease than he could ever be, and that he just hides it all behind
those bright eyes and  stupidly soft  cheeks.
So even if Katsuki were not so giving- and, oh, sometimes he tries not to be!-
Izuku would have his ways of drawing it out of him, of  making  him need it so
bad that he can’t help but give himself up entirely. He could make him beg, if
he tried hard enough, and the only reason he hasn’t gotten that far yet is
because Katsuki is stubborn and he is not cruel enough to drag it out that
long.
(Though, once, he earned a whimpered, “Don’t stop,” but Katsuki refused to
repeat it or speak of it again.)
But, as much of a tease as he is, Izuku can give back, if only Katsuki is
giving in the first place. For the most part, all he ever asks of his lover-
because, by now, Katsuki cannot deny that that’s what he is- is for him to
offer himself up and play nice and ask nicely for what he wants. These things
are a struggle, but the fact that Katsuki struggles through them shows just how
very giving he can be.
Today, he’s got his face pressed into a pillow, because it’s always easier to
do this if Izuku can’t see how needy his face may look, if the pathetic noises
he makes are as muffled as possible. Anything to make this easier- and today,
this  is Izuku already two fingers deep in his ass, with no intention of
stopping any time soon. Getting him to admit that this is something he wants,
that he wants to go  further  to see how much he can take before they have to
stop, was one of the most difficult things yet, but he is so giving he borders
on  generous , so he managed, eventually.
Every time they try this, they make it a little bit further, and every time,
Izuku always asks if Katsuki will want to let him try again soon. Always,
Katsuki wants to try again, and always, he wants to see just how far he can go,
and it is so hard not to play it cool. Once, he would have just said, “Yeah,
whatever, if that’s what  you  want,” but now, he knows that he has to simply
say, “Yes,” if he’s going to get what he wants. Izuku really is  such  a tease.
Today, they’re already two fingers deep, but that’s nothing, not at this point.
They’ve made it so much farther that this is just child’s play, and the way
Izuku wiggles his fingers slowly, like he thinks he still has to get Katsuki
ready for the third, would almost be enough to make him laugh, if he were in
any condition to do such a thing right now. But since he isn’t, he just bites
back a whimper and waits until Izuku starts working that third finger inside of
him.
“You still doing okay, Kacchan?” he asks softly, as he does so.
“O-of course, I’m f-fucking  fine ,” Katsuki tries to snarl, but the stammering
and the way his voice is muffled make him sound considerably less menacing.
It’s hard to keep up that image when he’s got fucking  Deku  trying to fit his
whole hand in his ass.
And that’s exactly what they’re doing, though it’s less  trying  at this point.
At least, the last time they did this, he managed all five fingers. The heel of
his hand was more difficult, and he insisted they stop for the time being,
despite Katsuki insisting that he was fine, that he could take more. This time,
he isn’t going to let Izuku stop, no matter what, because this time, he  knows
that he’s ready.
The fourth finger is Izuku’s pinky, so it hardly takes any effort at all, but
his thumb is more difficult, and he pauses to add more lube- so much that the
squelch  is almost sickening- before he tilts his hand, pressing the fifth and
final finger as far into Katsuki as he can manage, without fitting the rest of
his hand along with it. He rests like that for so long, giving Katsuki more
time than he needs to adjust, but not giving him anything else.
He won’t, not until Katsuki is a little bit more generous, a little bit more
forthcoming , and even then, he might not give it up. Sometimes, Izuku can be
giving, but sometimes, he can be stingy, and Katsuki knows that there’s a
chance this time could end up a dead end as well. He absolutely refuses to let
that happen, and he mumbles, “What are you waiting for?”
“Are you sure you’re ready, Kacchan?”
“I’m ready,” he says, knowing better than to talk back right now. He even lifts
his face a little bit so that his voice is more clear as he says, “I’m ready,
so just...just go ahead and do it, alright?”
“Alright. Just let me know if it hurts, or if I need to stop, okay?”
“Yeah, yeah…” Really, Izuku is such a fucking  tease .
He doesn’t tell him that it hurts, however, because he isn’t sure if the other
boy understands that it’s going to hurt no matter how much they prepare, at
least at first. He isn’t the one on the receiving end, so he really has no
fucking idea what it’s like, though Katsuki doesn’t like to think about that
for long because it only reminds him that  he  is on the receiving end, when
the roles should really be reversed. But his mind quickly goes blank as, after
applying even  more  lube, Izuku finally begins easing the heel of his hand
inside of Katsuki.
And it does hurt, as he’s stretched further than he’s ever been before, and
even with how slowly the other boy goes, it still takes him time to adjust and
accommodate. For a moment, all he can do is remind himself to breathe and to
relax, and that if he does both of those things then it’s all going to be just
fine soon enough. He just keeps breathing and keeps trying to relax, and then
it’s over, and Izuku’s hand is entirely inside of him, and once he’s  used  to
it, he feels an overwhelming sense of triumph.
A sense of triumph that is quickly pushed aside in favor of the absolute
pleasure  of the absolute  fullness , like nothing he has ever felt before. He
hates how goddamn  needy  he is with this, but he’s glad, just this once, Izuku
is being so very giving. More time passes as he catches breath, until Izuku
finally asks, “Are you ready, or do you want to stop?”
“I’m ready.”
One by one, he curls each finger to his palm, balling his hand into a fist, and
Katsuki sees  stars . He can’t hold back the broken cry that escapes his mouth,
nor can he help himself as he wriggles a bit, just enough to create a little
more friction. Not enough to hurt himself, but enough to really  feel  Izuku’s
fist inside of him, and to rub along his mattress. He’s going to get off on
just this, and he knows it, and even though he knows how damn pathetic that is,
it’s too late to do anything about it.
When Izuku begins to uncurl his fingers, it’s all over for him, and the fresh
sensation leaves Katsuki moaning out so loudly that even his pillow can’t
completely muffle it, and he’s too overwhelmed to care about the mess he’s
making on his bed as he comes, trembling uncontrollably. Even as Izuku pulls
his hand back out, taking it nearly as slowly as he did pushing it in, Katsuki
still shakes as he tries to recover and to catch his breath.
Weakly, he slumps forward, still not looking up at he does so. Izuku lets out a
soft laugh and asks, “Did you like that, Kacchan?”
“Whatever,” he mumbles, because he’s already been giving enough today.
