Summary
     Bullshit, Bakugo.
Notes
     second fic involving libraries in some way today lol
     this one was a commission
See the end of the work for more notes
The first time Katsuki sees them, it’s not on purpose. Hell, it’s  never  on
purpose, he swears, but that first time, he’s so surprised that it’s a wonder
he doesn’t shout, alerting the two to his presence. It’s not so much a surprise
seeing them together; the two of them started going out, and he  knows  that,
and it’s not like he gives a shit, he’s only annoyed because everyone else is
acting like it’s a big deal when it doesn’t fucking matter.
What’s  surprising  is finding them in a secluded area of the library after
school hours, doing anything but studying. As for Katsuki, he was actually
planning on studying, because, contrary to popular belief, he’s still a very
serious student, but it’s hard to get anything done when  some people  are
taking advantage of the mostly empty library.
It’s not like it’s the first time something like that has ever happened, but he
never thought he would catch Todoroki and  Deku  doing something like that.
He just barely keeps from making a noise to alert them to his presence, and he
pulls back, peeking out at them from behind a shelf. Why he doesn’t just walk
away, or even walk right up to them and give them hell for doing this in
public, he doesn’t know, and instead, he just watches.
Deku is in Todoroki’s lap, the chair leaned up against the wall behind them to
support their weight, and their heads rest on one another’s shoulders. Deku is
facing the wall, infuriatingly enough, so Katsuki can’t actually see the look
on his face- not that he wants to, mind you! But Todoroki has his eyes closed
peacefully, almost blissfully, and every now and then he can see his lips
moving, whispering inaudibly to Deku, and Katsuki can feel his blood boiling
from how downright  annoying  all of this is.
If only that were his only reaction.
As soon as he realizes what his  other  reaction is...well, that’s when he does
actually turn and quickly leave, definitely not wanting to get caught in this
state. He just wants to get home and fucking take care of it, and forget
everything, because none of this makes a bit of since. In no universe should
catching them like that  excite  him, knows that much.
And it’s not like he’s  jealous  of them, that has nothing to do with why it
pisses him off so much, knowing that the two of them are together. He knows
better than to think something so fucking stupid, and yet there’s still no
explanation for why he begins looking for them, same time, same place, in the
hopes of catching them again, or why he always catches himself fantasizing
about them when he’s alone.
There’s no way to explain just why he enjoys watching them so much.
~X~
He doesn’t know at what point they figure out that he’s watching, but
sometimes, they position things differently, so that Deku is facing him as
well, and he  swears  he’s made eye contact with both of them before. But they
never stop and he never leaves, and it becomes consistent, catching the two of
them together. It’s almost like it’s planned, like they’re doing this  for
him, but that would be ridiculous, and it would be even more ridiculous for him
to  want  them to. It’s all just a giant coincidence, one that makes no sense,
one that he could never really explain as a coincidence, even if he tried.
And then comes the day when Todoroki speaks to Deku in a voice that Katsuki can
actually hear, when he says something that makes his blood go cold. “Are you
ever going to actually ask him, Izuku?”
“Wh-what? Now?” Deku gasps out. “Are you...are you sure?”
Slowly, Katsuki tries to back away, as if he could actually escape now, but
Todoroki doesn’t even look at him as he says, “You don’t have to go anywhere,
Bakugo. If you want to keep this up, you can. Or…”
“Or...do you think maybe...you’d want to join us? Kacchan?” Deku looks up at
him with these big, hopeful eyes, and Katsuki has to say no. He can’t actually
do  something like this, no  way .
“Why the fuck would I ever want to…” His voice comes out, dry and cracked, and
he can’t even finish his sentence before he’s changing his tune. “If either of
you tell anyone about this, you’re dead. Got it?”
He hates how absolutely  ecstatic  Deku looks, and he hates the satisfied smirk
Todoroki wears, and he  hates  how quick he is to step closer, to get down in
front of them and take Deku’s cock between his lips like it’s something he’s
rehearsed, like it’s something he’s been waiting for. Deku whimpers
pathetically,  adorably , and Todoroki shushes him, reminding him of their
location.
Katsuki doesn’t know if it’s a competition or not, but all he can think about
is how  happy  Deku always looks, whenever he can see his face, and how  happy
he looks in class, when he’s talking with Todoroki, or whenever the two of them
are hanging out, and he decides right then and there that he’s going to win
this. In the back of his mind, he knows he shouldn’t  care  what makes Deku
happy, or be the one to worry about doing that, but he can’t stop himself from
caring. He’s never been able to stop fucking  caring , and he supposes that’s
how he’s found himself like this, sucking Deku off while he’s riding Todoroki.
Eventually, he supposes they’re going to end up trying other things, maybe
switching it up so that he’s the one fucking Deku- and he ignores the part of
his mind that wonders what it would be like for Deku to fuck him instead- and
then he starts wondering what they would do if it  wasn’t  Deku in the middle,
and why the ever loving  fuck  does he think this is something he wants to keep
up?
“Kacchan,” Deku breathes, tangling a hand in his hair, and Katsuki is so hard
now that he’s  aching .
“Is that good?” Todoroki asks, softly, but Katuski can sense the
competitiveness in his voice, the  jealousy  that Deku isn’t saying  his  name
this time, and, oh, it’s so  on . One way or another, he’s going to prove
himself a better lover, and if Todoroki is in on the competition, then that
just makes it all the more fun, and will make it all the more better when he
loses.
“Y-yes, I…” Now, he sounds like he could cry at any minute, and if that isn’t
just  like Deku, Katsuki thinks. “You’re both so amazing, I don’t…”
He clearly won’t last longer, and Katsuki suddenly wonders what they do about
cleanup, because like  hell  he’s going to do something so pathetically
submissive as  swallow , except he doesn’t stop even when Deku is panting and
tugging at his hair and trying to gasp out a warning. Instead, he just takes
him a little deeper, his tongue tracing along every inch of flesh it can reach,
and even though he knows that he’s inviting disaster, he just can’t  stop .
So he does end up swallowing, and he’ll give Deku shit for this later, he
swears he will, but the way the boy chokes back his moan, the way he trembles
in absolute pleasure, is something that even Katsuki can’t interrupt, and he
has to look up, to watch the way his face shifts. And then he pulls back just
as Todoroki gives a final thrust, exhaling deeply as he reaches his own climax,
and the three boys are left in absolute silence now.
For a moment, it feels like some sort of unspoken tension is finally broken,
and Katsuki supposes that’s true, not that he’s going to admit that to anyone
any time soon. Except the peace doesn’t last very long at all, as he remembers
just how  badly  he needs something,  anything  from them.
“So, what?” he asks. “Are you just gonna fucking leave me out to dry?”
Yeah, it looks like this is definitely going to turn into a regular thing.
