Summary
     Everyone has something they're into, right?
Notes
     happy kinktober you fuckers
     this was technically written for the stockings prompt
Shoto only catches the tail end of the incident regarding his female classmates
at the sports festival, and has so much on his mind at the time that it barely
registers. Barely, but the memory is still there in his mind, and happens to
pop up much, much later.
He doesn’t talk about the fact that he has a crush on Momo Yaoyorozu, both
because he isn’t sure if he’s close enough with anyone to talk about things
like that and because that’s just not the sort of conversation he’s used to
having. But the fact remains that he  does  have a bit of a crush on her, even
if he has no earthly idea what one is supposed to do about feelings like that,
and the memory of her in a cheer costume comes back to haunt him not long after
the two of them begin to get closer.
Suddenly, he closes his eyes and he sees her in that colorful costume with the
short skirt and the tall socks, and he may not be familiar with how to act
around someone he likes, but he’s definitely familiar with the feelings that
overtake him. And it’s not like it’s the first time he’s ever felt this way
about Yaoyorozu; she’s a very attractive girl, and he’s not the only person to
notice that. Still, it’s the first time he’s felt this intensely over something
so specific, and he knows that it’s that damn costume to blame.
But there’s nothing he can do about that, because he doesn’t feel like there’s
anything he can do about his feelings for her in the first place. And even with
they start to get quite a bit closer, and it becomes very clear that they’re
headed towards something more, he still does what he can to keep any impure
thoughts to a minimum. His upbringing has had little to do with relationships,
and it’s not like he has anyone to look up to, in terms of romance, but he
still knows enough about being a gentleman. He knows better than to look at her
for too long or say anything that could be misconstrued, or let his mind wander
too much when they're alone together.
And yet he kisses her one day anyway, without much idea of what prompts him to
do it. He kisses her when they're alone together, and Yaoyorozu returns his
kiss slowly but eagerly, and her hesitation is adorable. Everything about her
is adorable, he starts to think, and all thoughts of being a gentleman go out
the window so quickly that it’s almost as if they weren’t there to begin with.
In his defense, she seems just as eager as he does, and if he were truly a
gentleman, than he would have to give in to whatever she wanted, wouldn’t he?
Shoto really has no idea what he’s doing, and when they pull apart, her face is
red and he’s sure that he is too as he glances off to the side. “Sorry if
that’s...moving too fast. I haven’t even told you that I like you yet, have I?”
Her blush deepens as she mumbles, “I...like you as well, Todoroki.”
“You can use my first name, if you want to,” he replies, also mumbling.
“A-ah! Well, then, you can use mine if you want...Shoto.”
“Thank you...Momo.”
It takes them quite a bit to recover from that and get back on track, and yet,
somehow things manage to escalate quite a bit farther than they should, and
Shoto knows that he’s definitely taken things too far.
~X~
Any intimacy that follows is awkward and clumsy as they try to figure each
other out. What starts as the two being too shy to make moves on one another
ends in both of them searching for whatever moments they can get alone
together. It's times like this that Shoto is reminded that, despite everything
he's been through, he's still young, and still very susceptible to youthful
desires, no matter how base they may be.
The image of Momo dressed as a cheerleader begins to plague his thoughts more
and more often, during that time. He reminds himself again and again that it's
not right to bring something like that up, regardless of how close they have
become.
“If you’ve made something before, it’s easy to make it again,” he says one day,
both knowing that he’s stating the obvious and knowing that he’s leading into
the  one thing  he’s promised himself not to say.
“Yes, the more I work on something and the more I learn about it, the more it
becomes like an afterthought to create,” she says, confusion written on her
face. “Why are you asking that right now?”
“During the sports festival...you made those... outfits , didn’t you?”
Momo’s face goes a bright red as his words dawn on her, and Shoto wonders if
it’s too late for him to backtrack, too late for him to get out of this even
though a very large part of him desperately doesn’t want to. “Y-you mean those
horrible costumes?” she asks, in a soft voice.
He nods, looking away and mumbling, “I didn’t think they were that horrible…”
“I...I’m not sure...you don’t mean…?”
“I don’t want to make you uncomfortable,” he says. “If you hated it that much,
please just forget I said anything.”
She actually goes so far as to cover her face with her hands, and he feels bad
for even thinking about how cute  that  is right now, and she takes a moment
before she says anything else. “I-I guess everyone has something that they’re
into, right? And if it were for you...I wouldn’t mind wearing something like
that again.”
“Are you sure? I wouldn’t ever ask you to do something you don’t like, so
please…”
“No, like I said, if it’s for you…”
The two of them go back and forth like this for quite some time before they
finally decide that it’ll be okay to try, even if it’s just this once, and Momo
leaves the room, asking him to wait for her. When she returns, she’s staring at
the floor with bright cheeks, and she’s decked out in the very same costume
that’s haunted his memories, right down to the pom poms in her hands.
“I didn’t know if these were necessary, but I wanted to be safe and…” She
pauses as she finally makes eye contact with him, noticing for the first time
the way he’s gawking, the way his jaw has nearly hit the floor. “Wh-what is
it?”
“You look amazing,” he says bluntly, a bit too bluntly, but he’s barely in his
right mind anymore. After fantasizing this for longer than he’d care to admit,
he’s pleasantly surprised that his imagination is nothing compared to seeing
her like this in person. Her shyness regarding the outfit only makes it more
appealing, and he wonders how the hell he’s let himself fall victim to his own
desires like this. In the back of his mind, he knows he should be stronger than
this, but it’s a little hard to do that with Momo looking like this.
“I’m sorry, but I don’t know if I can do anything...in character, or at least,
I don’t know if I can do it well.” She lifts the pom poms halfheartedly as if
to illustrate her point, but Shoto rises without a word, closing the distance
between them and pulling her into a kiss, and she drops them to the floor.
Really, it wasn’t necessary for her to make them at all, nor is it necessary
for her to try any roleplay, because he’s past the point of being able to
resist her like this, and the only thing he can think about is what he’s going
to do to her now that he’s got her like this.
Turning her and pushing her back, he doesn’t break the kiss until he’s guided
her to her bed and eased her onto her back. At the very least, they’ve gotten
to  this  part many times, no matter how awkward those times may be, and he
knows where to go from here.
“Shoto,” she breathes, looking even more embarrassed as she speaks. “I
didn’t...I’m not…”
He pulls back and leans down between her legs, pushing up her skirt to confirm
his suspicions about what she’s trying to say. She isn’t wearing anything at
all under the costume and he swears he feels his heart stop for a second there.
Momo squirms a bit, and he knows she must feel awkward with him just staring at
her, so he leans his face forward and presses his tongue inside of her, earning
a soft gasp.
He's still learning how best to do this, but she really seems to like it every
time he does, so he always keeps it up. She moans softly as Shoto delves into
her, trying to recall each movement that's driven her crazy in the past. He
knows where she’s the most sensitive, and he traces his tongue along inside of
her, teasing at her until he’s got her moaning uncontrollably, her stiff
demeanor falling by the wayside as she gives in to him. All the while, he runs
his hands up and down either leg, feeling the way the stocking hug the curves
of her calves.
Sometimes, he finishes her off like this, and, though he’s sure that’s the
polite thing to do, right now he’s very much past the point of being polite and
he’s aching so much for her that he can’t wait any longer. He pulls back and
stands up, and she lets out a soft cry of what might be disappointment at the
loss of contact. But her disappointment doesn’t last long as he pushes her
skirt up further and he positions himself, letting Momo wrap her legs around
his waist as he sinks inside of her.
They both moan almost in perfect unison, both overwhelmed for a moment, just as
they always are at this point. No matter how many times they do this, Shoto is
always just as overwhelmed, and he knows that he’s doomed himself by ever
allowing himself to learn what it is he was missing out on all this time. Now
he knows he’ll never be able to get enough, of this or of her.
Momo looks up at him with the most enticing- and he wishes he could think of a
better word but he can’t- look on her face, biting her lip as she gasps out,
and she’s already so close just from before, which is lucky for him, because he
knows he can’t last much longer. Not when she’s dressed like this, beneath him.
He can feel the tops of her stockings rubbing against him where her legs are
wrapped around him, and even that sensation alone is maddening enough to leave
him on the edge, just barely holding back until he knows she’s satisfied.
The frantic pulse of her orgasm is, of course, too much for him to handle once
she’s finally there, and he’s there with her so quickly that he doesn’t even
have time to realize it’s happening. They moan in unison once again, and then
he slumps over, just barely supporting himself on top of her as they both try
to recover, breathless.
It’s not the first time they’ve done this, but it’s the first time they’ve done
it like  this , and Shoto wants to ashamed of how quickly he went, but he’s too
blissed out to care right now. Even after they’ve begun to recover and
straighten up, he’s in such a good mood that he even thinks of a joke.
“You know, I could wear it for you next time,” he says, and it’s only when he
sees the look on her face that he realizes he sounded too serious. “I...that
was a joke.”
“O-oh,” she replies. “Oh...well, I...wouldn’t have minded it if wasn’t.”
Oh.
Well, then.
