****** a quick lesson ******
by Birdschach
Summary
     “Hm, so you’re sure I don’t know what I’m doing?”
     “Yeah. Wouldn’t fucking say it if I weren’t. Geez, such a nerd.”
     “So why not give me a lesson?”
     “T-the fuck!? A lesson!?”
     “Yeah. Maybe if I had an example of what was really good then I’d do
     better. I mean, you’d win in the end, y’know?”
Notes
     Happy Birthday, Hannah!
“Ha, like you even know what you’re doing! Fucking nerd,” Katsuki taunts,
though by now Izuku knows better than to take him seriously.
“You definitely didn’t complain last time, Kacchan,” he responds, trying his
best not to smirk openly.
“W-what did you just say!?”
“Well, last time I sucked you off, you kinda went to pieces. Muttered something
about how ‘fucking innocent’ I looked?”
“I don’t know what you’re talking about. Quit making up weird shit, Deku. Like
I said, you don’t have any idea what you’re doing in the first place. Couldn’t
have gotten the best of  me,  that’s for sure.”
“Hm, so you’re sure I don’t know what I’m doing?”
“Yeah. Wouldn’t fucking say it if I weren’t. Geez, such a nerd.”
“So why not give me a lesson?”
“T-the fuck!? A lesson!?”
“Yeah. Maybe if I had an example of what was  really  good then I’d do better.
I mean, you’d win in the end, y’know?”
“You ever planning on cutting this weird shit, Deku?! Since when are you so
forward anyway? You really think you can  ask  me to suck your dick like this?”
“If you can’t give me a lesson that’s okay! I’m sure I can get better on my
own.”
“We both know a nerd like you only gets better by watching someone else. Ugh,
fine , I guess I’ll do it. But I don’t  want  to, got it?!”
“Of course, Kacchan…” Izuku says, smiling. They stand in Katsuki’s room, as his
parents are often working until later on in the evening, giving them plenty of
time for  this  after school. Of course,  this  is something neither of them
are really quite sure of yet. As time goes on, they grow closer together, but
neither have tried to define what they are, exactly.
And as Katsuki crosses the room, and aggressively pushes his lips to Izuku’s,
it seems today will be no different. As their kiss continues, with Izuku
positively  melting  into it, Katsuki works his zipper down, and slips his hand
inside. He grips Izuku, and the sudden contact spurs the boy on even further.
He was already well on his way to getting hard, but the way Katsuki grabs him
only speeds it along.
“I’m not surprised you’re already so excited, fucking nerd,” Katsuki says,
breaking their kiss.
“I… well, you can’t blame me, can you? You’re amazing, after all,” Izuku
responds, grinning at his friend.
Shaking his head, and not offering another word, Katsuki drops to his knees.
For a second, he hesitates, face mere inches from Izuku’s cock. But his
apprehension fades, his lips part, and he takes Midoriya into his mouth.
Immediately, the boy leans back, resting his weight on Katsuki’s desk, and
sighs happily. Katsuki looks up at him, their eyes locking together, as he
begins bobbing his head up and down Izuku’s length.
As Katsuki moves, he allows his tongue to  drag  along the shaft, a technique
that works wonders, especially as he works his way further down. As much as he
protested, Katsuki actually rather enjoys this. It’s not anything he would ever
admit to, naturally, but the experience really isn’t that bad. Especially with
how adorable Izuku looks, eyes half-lidded, really losing himself in the
feeling of Katsuki’s mouth.
That’s not to say he’s not paying attention, however. As happy as Izuku might
look, he’s on high alert. He watches each and every motion, tracks Katsuki’s
shifts in expression, and tries to memorize his patterns and rhythms. Ideally,
Izuku would have a notebook to jot his notes down in, but there is no way he
could get away with  that  without Katsuki teasing him mercilessly.
“Taking notes on sucking dick?! That’s a whole new level, Deku. Nerdy and
weird, all at once. It would be impressive, if it weren’t so damn stupid!”  he
might say, and somehow Izuku can hear every word in his voice, as if he were
truly speaking to him.
Though as Katsuki continues taking more of Izuku into his mouth, he is far from
any ability to speak. At best, he would be able to manage some muffled mumbles,
but the boy doesn’t even try. After all, this is just a lesson. He wants to get
it over with as quickly as possible, no matter how Izuku might look, or how
cute his little whimpers are, or how the idea of pleasuring him has a certain
thrill all on its own, a thrill which is quickly getting Katsuki hard.
“Are you enjoying this, Kacchan?” Izuku asks, and Katsuki freezes. There’s no
way in  hell  he can see that Katsuki is hard, and the boy has remained silent
even as he felt his arousal mounting. So why the hell would Izuku ask such a
stupid fucking question? Katsuki decides to ignore him, taking him deeper
instead. He also speeds up, working his way to a pace Izuku can hardly handle.
In only a moment, Izuku speaks up again.
“K-Kacchan, I’m almost there… you should probably pull off, I’m…” Izuku says,
desperately trying to hang on as Katsuki shows no sign of slowing. He knows it
won’t go well if he comes in his mouth, but what else can he do besides warn
him? As a final gambit, he tries pushing Katsuki off of him, but he’s in no
real state to overpower Katsuki, and the explosive young man easily grabs his
wrists, pushing them back against the desk.
Pinned, and with Bakugo showing no sign of stopping, Izuku finds he can hold on
no longer. With a groan, he comes, his seed spilling into Katsuki’s mouth.
Immediately, and with a sour expression, Katsuki pulls back, and rises to his
feet. He spits the come out, not at all worried that it is on his own bedroom
floor.
“What the fuck was that?!” he asks, furious. “Did I say you could do that?”
“N-no, but Kacchan… I tried to warn you, and even tried to push you off, and
all you did was pin me down.”
“As if I’d do something like that. Why would you make shit like that up?
Fucking Deku. I’m going to fucking kill you for that, you know!”
“But I-”
“Don’t wanna hear it, Deku. You’re definitely done for now! Unless you make it
up to me,” Katsuki says, practically glowering at Izuku.
“How can I do that?” Izuku asks, eager to please.
“Do I have to spell it out for you? Damn it, Deku. I… I want you to fuck me,
alright?!” Katsuki admits, his request hardly even audible.
“I couldn’t really hear you, Kacchan… what was that?”
“I want you to fuck me, damn it! Is that so hard!?” Katsuki says, and it is
then that Izuku glances down, noticing just how  hard  his friend is.
Apparently, he enjoyed himself quite a bit more than he let on.
“I can do that! Just… relax, and bend over the bed, like usual, okay?”
“Why? It’s not like I want this or anything,” he says, loosening his belt and
getting into position, allowing his pants to fall to the ground.
“But you just asked me to do it, Kacchan!”
“Oh yeah right, where’s your fucking proof? Look if we’re doing this, then get
on with it, we don’t have all night,” Katsuki says, and Izuku can’t help but
wonder just how much longer this is going to go on, before he finally leaves
for home. If experience is any indicator, it’ll be moments before Katsuki’s
parents usually get home. Needless to say, they’re not going to get any closer
to figuring out what they are to each other tonight.
