The Luck of Aizawa Shouta

Summary:

Shouta unexpectedly goes into heat in the middle of class. Luckily for him, his husband isn't far away. Not so luckily for him, his class has no idea he even has one.

Notes:

A fairly self-indulgent fic, ngl.

Warning: While the EraserMic is COMPLETELY consensual in this fic, it does vaguely imply that it could potentially not be (i.e. why the students are getting all protective over Aizawa in the first place). Just a head's up for that.

(See the end of the work for more notes.)

Work Text:

“Take out-” Shouta paused at the sudden warmth on the back of his neck. Green eyes sharpened as Midoriya’s gaze shot up from yet another notebook. Shouta ignored him as he cleared his throat and continued. “Take out your English textbook. I know you have a test later and some of you are not going to pass.” Several students sunk into their seats. “But there may still be time to-”

To earn extra points, was what he’d been going to say, before another surge of heat had him stiffening. Fire crept over his skin and under his skin and into his very veins. It flowed up from his neck to his cheeks and then back down again to his chest and stomach and-

Shit.

Several of the students were now openly staring at him while others - Bakugou - were pretending not to care as they flipped through their notes without actually looking at them.

He pulled out his phone and shot off a quick text to Hizashi.

“I have to go,” was all he managed as he ignored his desk in favor of the door.

“Sir! Do you need our assistance!?” Iida’s arms flailed robotically as he stood up from his seat.

“Study,” Shouta said. His hand curled around his phone as he slipped it back into his pocket.

They had special rooms for exactly this sort of emergency. All he had to do was get there and Hizashi would come take care of the issue. Everything would be fine.

Or, it would have been fine if his body hadn’t decided right then and there that it didn’t feel like waiting. He let out an involuntary gasp as he fell to one knee and then both knees as he parted his legs, lest the tightness in his pants make him do something he’d immediately regret.

His students shot to their feet, several of them racing over before he had the chance to tell them not to. He tried to waive them off but most paid him no heed as they formed a loose circle around him. Damn it. He would expel all of them.

“Lea V E.” The word came out as barely a word, his voice betraying him in the middle of it.

He sighed as the noise began.

“Sir, what’s wrong?”
“It couldn’t be villains again, could it?”
“Better keep an eye on the exits just in case!”
“Someone get Recovery Girl!”
“Maybe we should grab his sleeping bag?”
“He might need water! Does anyone have a water bottle?”
“I’ve got one!”
“Tell us what you need, Mr. Aizawa!”

“I ne E d- I-” He tried to push the words out, but his mouth wouldn’t do what he wanted it to do and his thoughts fled as quickly as they formed, instinct taking over in their place. He needed-

He needed to fuck.

“Shut up! He’s trying to talk!” Bakugou yelled.

Shouta’s gasping breaths were loud in the suddenly quiet room, sucked in and out through gritted teeth as he tried not to moan. Sweat trickled down his back, and he shook from strain as he told his body that it was not allowed to start humping the air in front of twenty impressionable children. He remained completely still. He could do this. He just needed Hizashi. Hizashi’s lips and his tongue and his cock and his cock and his coc-

He pressed his lips together.

“He doesn’t look too good,” Midoriya whispered.

“I said shut up!”

Midoriya went flying as Bakugou kicked him in the back.

“I think I’ve seen this before. There was someone, once, at the mall…” Uraraka paused, and Shouta didn’t need to look to see the flush undoubtedly coloring her face. The only good thing about this unbearable heat was that his own cheeks couldn’t possibly get any warmer.

“What is it?” Yaoyorozu asked.

“I think Mr. Aizawa is in heat.”

There was a beat of blessed silence and then the room blew up.

“I didn’t know he was an omega.”
“Yeah, he doesn’t really seem the type.”
“Don’t stereotype!”
“Are we sure he’s really in heat though? I don’t smell anything.”
“Well, duh. You can’t smell it if you haven’t presented yet. Everyone knows that.”

“Should we get Recovery Girl?”
“What’s she gonna do, kiss his dick?”

“He looks warm. He needs water!”
“See, I told you!”
“Now’s not really the time for ‘I told you so’ don’t you think?”
“My bad.”

“He doesn’t have an alpha, does he?”
“What do you think?”
“I guess you have a point…”

Shouta’s eyes narrowed. What the hell was that supposed to mean?

“I-” He took a couple of calming breaths. “I’m fine. Back up.”

They obeyed him, scuttling back like startled mice as he carefully pushed himself to his feet.

He ran a hand through his hair. It came back damp with sweat. “Class is dismissed.”

“Is it safe for us to leave?” Midoriya asked, his eyes darting between him and the door as if he expected an entire hoard of rampaging alphas to come through at any moment. “None of us have presented yet so logically-”

“Enough.” His hair flew as he snapped. Midoriya shrunk in on himself, and he softened his voice, his hair falling back to his shoulders. “All of the teachers at U.A. are on suppressants. No one is going to bother me.”

This was, naturally, when Hizashi chose to come bursting through the door.

“Sorry! So sorry! You weren’t in the designated…” Hizashi trailed off as he looked around.

Shouta pushed himself back against the chalkboard before he could do something stupid like drop to his knees and present himself. This had the unintended effect of making it look as if he were shrinking back from the man.

His students immediately moved to put themselves between them, and the part of him that wasn’t either shaking with need or pissed off beyond measure was sort of touched at the ferocity of their glowers.

“HizZZaAaaaaa-” The would-be word petered out into an aching cry and then nothing at all as Shouta slammed his hand against his mouth. He would not beg to be fucked in front of his students. He would not.

Hizashi’s nostrils flared and it was only a miracle that had kept any of the others from smelling just how much Shouta wanted him right then. Smelling just how slicked he was. Thank every deity known to man that none of them had been early presenters.

“Hey there listeners! Good job keeping him safe. I’ll take it from here.” Hizashi gave them a smile and a double thumbs up.

“No, you won’t.” Bakugou took point as he pressed into Hizashi’s personal space. “Back off.”

The entire class crowded in around Hizashi, with Midoriya and Todoroki stepping in behind Bakugou. Bakugou glanced at them but for once didn’t look ready to murder either boy. So that was all it took. Apparently all this time all he’d needed to do was lose complete control of himself and fall back behind them like some sort of damsel in distress.

Marvelous.

“Huh?” Hizashi cocked his head to the side.

“You heard me!” Bakugou took another step forward.

Hizashi sent an incredulous look in Shouta’s direction as he allowed himself to be pushed back. He raised his hands in surrender. “Hey there, no reason to fight. I’m just here for my husband.”

That gave Bakugou pause, but not for long. Shouta’s hair flew as Bakugou got up into Hizashi’s face.

“Bullshit!”

“Mr. Aizawa’s never mentioned having a husband…” Midoriya’s voice was tentative as he spoke. He jerked back when Bakugou snapped a glare at him over his shoulder.

“Midoriya is correct,” Iida agreed.

“He’s never…Shouta, really?” Hizashi gave him an exasperated look. Fondly exasperated, as Hizashi would say.

“They didn’t need-” He needed. Right then. He didn’t care anymore if the students watched. It would serve them right for not leaving when dismissed.

Nonono. He did care. He wouldn’t- He didn’t want- He did want-

Shouta shook his head. “LA-Later.”

Hizashi took a step towards him. The students allowed it, though they stayed between them still. Hizashi didn’t even seem to notice them as his eyes crawled up and down Shouta’s body. Shouta sucked in a sharp breath. His nipples pebbled beneath his track suit, and he had to press his palms flat against the chalkboard behind him so as to not run his hand over his cock.

“Do you have any proof of that, sir?” Jirou asked.

“Proof?” Hizashi murmured.

“That you’re married,” Jirou clarified, “It’s not that we don’t want to trust you, but, well…”

“But we don’t trust you,” Todoroki said bluntly, “People have a tendency to do things they wouldn’t normally do when heat is involved.”

Hizashi tore his eyes away.

Shouta slumped into the chalkboard. This was too much. At this rate, he was going to end up sticking his hand down his pants and dealing with the issue himself.

Slick slowly trickled its way down his inner thighs. He was so, so unbearably warm.

“We don’t really carry anything with us while at work. Too much chance for an attack to damage it. I suppose I could call in one of the other teachers…” Hizashi’s eyes strayed back towards him. Shouta’s stomach quivered. “Though I think only All Might would be able to respond, and he’s in the middle of an evaluation right now.”

“All Might?” Midoriya asked, because of course that would get his attention.

Shouta closed his eyes. In and out. Slow, steady breaths. Hizashi would take care of this misunderstanding and then he would have his alpha. Just a few more minutes.

“I don’t think bringing in another alpha would solve the problem,” Mineta said.

Shouta cracked an eye.

Another alpha?

“All Might’s not an alpha,” Midoriya said, giving him a strange look. As if this should be something he already knew.

Slow and steady. Deep breaths.

“He’s not? Seriously?”

“Yeah man, everyone knows that,” Kaminari said.

“Dumbass,” Bakugou muttered.

“But he’s All Might!”

“Dude, stereotype much?” Kirishima gave him a disgusted look.

Slow. And. Steady.

“Well how was I suppo-”

Shouta’s capture weapon shot out. He weaved it between the students and wrapped it around Hizashi’s waist before yanking him over to him. He grabbed his husband by the lapels and smashed their lips together the instant he was within range, not even bothering to let his end of the weapon drop. Hizashi’s arms wrapped around him, and he picked Shouta up and threw him down onto his desk.

Shouta could see his students gaping out of the corner of his eye.

“You have five seconds to vacate the classroom or every single one of you is getting expelled.”

“Sir-”

“Five.”

“But-”

“Four.”

They seemed to get the hint as they began frantically pushing their way out the door. Bakugou glowered at Hizashi but allowed Kirishima to drag him out. Midoriya gave him one last look, his hands fidgeting in front of him as Uraraka gently guided him into the hallway. The door slammed shut behind the last of them - Iida, naturally, the boy taking it upon himself to make sure everyone got out in time.

Shouta spread his legs.

Finally.

=====================

“I can’t believe you never told them we were married,” Hizashi whined. He wrapped his arms around Shouta and carefully adjusted them both so that he could lay aside him more comfortably until his knot shrunk down.

Shouta sighed and squished his pillow closer to his chest. They hadn’t actually had sex in the classroom, thankfully. Hizashi had managed to pull himself together enough to drag Shouta to the emergency heat room, amid a group of nervous hallway-lurkers. At least they’d been left alone after someone - Midoriya - had called All Might and asked if they were actually together or if they’d both lost their minds to hormones.

“You never told them either,” Shouta pointed out.

“Yeah, well, they’re not my class.”

“Have you been teaching some other group of students that I don’t know about?”

“You know what I mean. The rest of us might teach them, but it’s all ‘Mr. Aizawa this’ and ‘Mr. Aizawa that’ with them. Even All Might says so.”

“Is that so?” Shouta asked, trying to play off the warmth building in his chest that had nothing to do with his heat.

Hizashi pressed a kiss to his back. “That’s so.”

“Well, they’re going to have to find a new teacher to ‘Mr. Aizawa this and that’ to. I’ve decided to retire,” Shouta said, not meaning a word of it.

Hizashi snorted and gave him another kiss.

Shouta sighed. Tomorrow was going to be one hell of an awkward Thursday.
