Midoriya Izuku was adorable off battle, intense while fighting, and an omega who couldn't be messed around with...to an extend. The side most did not know but a special few knew, was Izuku's dark secret. The unordinary way he had sex during his heats and the way he welcomed his alphas’ ruts, heat or no. That's right. Alphas. With no other than the top students of U.A. No insult to be beheld on him. Nor did the insult came upon those who took Izuku in. The top students of U.A also fucked one another which was out of place being their status as alphas and the strongest in U.A as of now. Times had changed and there was nothing wrong with exploring and experimenting. So far it's been great. Nevertheless, Izuku was always the best one to get laid with. Button or not. Being an omega and all.

What these top students who got to fuck Izuku in days he serves button didn't know, was that Izuku had a sexual relationship with Bakugou Katsuki, his own fated rival, as well. A relationship that Katsuki was starting to get serious with.

“He'll be here any moment now,” Izuku whispered in desperately stuttered breaths against Katsuki's ear before slipping in a delightful whine of pleasure. “F-fuck me,” he said and gasped at the rising thrust of his rival's hips. Hissing and moaning were instruments that spilled from his gaping mouth, resting his emerald eyes on the blonde spikes of his partner.

Katsuki was a panting and lustful mess, resting his temple on Izuku's cheek as he groaned in pleasure. “How close are you?” Katsuki was able to ask.

“We've just started three minutes ago,” Izuku reminded, gripping Katsuki's bare shoulder. “We should have done this - ahhh!” Deku moaned at the thrust, his butt cheeks being groped by Katsuki's warm hand. “He'll be here soon. Why did we have to do it now?”

“Don't complain,” Katsuki said and looked up at Izuku. “I know you wanted me since morning the same way I did all day.”

“But rules are rules,” Izuku said, panting. “You know Todoroki's rut is today and he won't like waiting.”

“I thought he was the soft type,” Katsuki said.

“He is but his ruts could be...rough.”

“You like that don't you?”

“I go both ways.” Izuku ran his tongue on Katsuki's neck and up to his scent gland making Katsuki sigh. Izuku added, “Today feels like a rough day.”

Katsuki grabbed Izuku's chin and lifted him to face him, his movements slowing for a brief moment. “I wish I can fuck your ass in the cafeteria so everyone can see the beauty you are,” Katsuki said and leaned near his lips. Tongue out to slide with Izuku's before crashing into their breathless worlds.

How daring it would be to do such act in public. It would be the end of their careers perhaps. But the idea was so exciting and it made their dicks throb more in dirty excitement. How good would it feel to be fucked in front of the school? In front of Uraraka, Lida, Kirishima, the rest of the crew and even pitiful Mineta. Izuku scolded himself for his dirty thoughts but he couldn't help it. Such fantasy was enthralling to see in action.

Perhaps have someone record it as well...Alright, that was too much. His mother will eventually end up seeing it and he would be embarrassed.

...But his mother was an omega as well. His mother had experienced what he is currently experiencing. Right? It was part of human nature. An art form to say.

A trail of saliva in between them was enough to know their mouths were part of their own set of dicks and with their own set of orgasms. “Fucking me in the cafeteria wouldn't be a bad idea,” Izuku said, moving his hips up and down and grinding on him.

“It would, wouldn't?” Katsuki agreed.

Both of them heard a faint burst of laughter from down the hall. “Todoroki! You coming with us to eat?” called Kirishima.

“I've got things to do. Next time,” Todoroki said.

“Too late,” Izuku told Bakugou.

“Fuck, come on,” Katsuki begged as he kept thrusting.

“Sorry...Hit my prostate at least,” Izuku indicated quickly and leaned back to rest his hands on the bed sheets to angle himself in that particular spot.

Katsuki shifted as well, knowing exactly where it laid. Izuku covered his mouth as a moan slowly came to rise. “S-shiiit. Fuck,” Katsuki cursed, resting the back of his head on the wall. Izuku was surprisingly warm and all the self-lubrication paid wonders to the head of Katsuki's dick. Luckily the bed didn't creak, leaving room for their erotic movements. Which was of no use as the walls were soundproof from the outside in.

“Come on,” they both whispered and looked at each other as Katsuki jerked Izuku off. So daring. So splendid.

The footsteps came closer to Izuku's door.

Katsuki slipped out of Izuku and gestured him to turn around in all fours. “I should have brought you to my room, not yours,” Katsuki complained.

Izuku gazed at the mirror in front of them after doing so, watching how Katsuki licked his lips. Then biting his lips as he slipped back in to feel the sensitive warmth of Izuku's hole. How could this feel so perfect, good, delicious and painful to the point of hot tears running involuntarily down the corner of Izuku's eyes? He wanted this sensation to last forever. Wanted to feel the urge of lust to last for eternity. Be Katsuki's until existence no longer existed. But he couldn't help wanting another alpha to take him down like a slut he is. Like a slut everyone of his alphas are. To make Katsuki realize he could lose to another alpha.

He felt Katsuki run his tongue on his scent gland in desire, teeth biting slightly. “Kachaan,” Izuku pleaded as he continued to move his hips back for more. This may finally be the moment Izuku's been waiting for.

“You know I'm yours truly,” Katsuki whispered to him. “We were meant to be.” He kept teasing Izuku's scent gland and it made Izuku shutter more and more. Just waiting for him to take the bite of a lifetime.

“Bite me,” Izuku pleaded. Katsuki gave it a peck and removed himself away from the commitment leaving Izuku disappointed.

Todoroki knocked on the locked door. “Midoriya, you here?”

Katsuki stopped and cleared his throat, running a hand on Izuku's butt cheek. “I think it's time he knows I've taken you under my dick as well,” he told Izuku with half-lidded eyes staring lazily to the door.

“Maybe tell him you've finally claimed me?” Izuku suggested knowingly.

“Don't hurry yourself,” Katsuki said with a thrust.

“Fine. But if Todoroki sees you, then you'll have to be part of the group's rules,” Midoriya said in a low voice.

“Which is?” Katsuki said as another knock came in.

“Midoriya?” Todoroki said from the other side.

“If you have sex with me under the knowledge of my other alphas, you fuck them as well.”

“Really?” Katsuki smirked in amusement, arching a brow. “That's out of my line of sight. Your rules?”

“Yeah, and it's pretty great when you get to it,” Izuku said. “I'm going!” Called Izuku to the door. He turned around to look at Katsuki and said, “What is it? Leave now unfinished or continue but now being part of the group?”

“Tch,” Katsuki cursed and grabbed Izuku's arm to pull him to Katsuki's chest. “Let's welcome him, shall we?”

Without disconnecting from each other, both walked to the door. The movement added friction to Katsuki which caused him to halt and thrust a few times before controlling himself and continuing to the door.

Izuku opened the door allowing only half his face to peek out. Todoroki caught sight of his flushed cheeks and sweaty forehead. “You alright?” Todoroki asked as he walked in. “What? Did you start without me?”

Right after he said that, the door was closed. Locking it and pushing Todoroki on the wall. He was the most tallest between Katsuki and Izuku and he noticed Izuku wasn't the only one in the room. Naked and with the smell of sex filling the room.

Before Todoroki could ask anything, Katsuki pressed Izuku in between them and Izuku started to grind against Todoroki's lower parts. Todoroki couldn't help gasp.

“We've got a new member on our team,” Izuku told Todoroki. “And he's begging me you fuck him next,” he said in the most seductive tone Katsuki had ever heard.

Katsuki was fucked.

__________

There was no jealousy that could break the moment as Katsuki stared at the sight before him. Todoroki, in the desperation of having his dick filled with an omega's wet hole, had not given thought to taking off his white shirt. Though he did remove his jacket.

Katsuki laid on the bed, legs spread as he fingered himself in preparation of Todoroki's dick or hopefully Izuku. He loved it when the omega will challenge the social norms and fucked the senses out of Katsuki.

While doing so, Izuku had his hands planted beside Katsuki's arms as Izuku was being fucked from behind. Gasping without a care in the world. For a moment Katsuki indeed looked jealous. Izuku gasped a bit more than with Katsuki and he wondered why. I guess he'll find out in a few but his best guesses were it had to be related to his quirk.

Izuku had not left his gaze off Katsuki unless the pleasure was too much to keep his eyes open.

“I'm close,” Izuku said and Katsuki watched Todoroki jerk Izuku's cock quickly as he too was accelerating his speed.

Izuku looked drained in heaven. In a matter of seconds the familiar arch of his back, the clench of his teeth, furrowed eyes and curling toes and hands declared the point of victory.

Explode. Gasp.

Release. Shutter

Release. Hmmm.

Release to its full. Twitching.

Both Todoroki and Izuku jerked forward. Katsuki having the advantage, ran his hot tongue onto Izuku's neck. For Izuku, there was nothing more pleasurable than helping Todoroki seek the edge of an overwhelming wave of electricity with his own dripping hole. The way Todoroki's breath was out of control, desperate like a dog in heat fucking his own bitch, made Izuku feel powerful. Yet feeling his scent gland being teased by Katsuki once again made him weak and vulnerable.

“You think you'll be ready to take me, Todoroki?” asked a breathless Katsuki.

Todoroki looked up from Izuku's green hair and leaned near Katsuki's face. “I should be the one asking you that,” he said in a low voice too intimate that made Katsuki's body shiver in anticipation.

“Hope those faces Deku's been making are the real deal,” Katsuki said.

“I'll make sure of it,” Todoroki whispered before engulfing Katsuki with a feverish kiss.

Izuku was right. Todoroki had it hard in ruts.

__________

No one could have imagined Katsuki Bakugou could be so open to Todoroki taking him in with so much dominance, Katsuki couldn't help plea for more. Drool came out of Katsuki's mouth and his red eyes were blurry with hot tears.

“Mnn ooorre hah ahh,” Katsuki tried to say coherently with no avail, pressing his back head against the pillow as if trying to get away from this missionary position.

Izuku sat on his chair and was stroking his dick back to life. Katsuki would now realize the reason behind Izuku's constant gasps. The way Todoroki manipulated his fire quirk in order to warm up have of his dick and the insides of his wet hole.

The ringing of Izuku's phone did not stop Todoroki, rather caused him to place a hand above Katsuki's drooling mouth and continue his thrusting.

“Hello?” Izuku answered. “Hi, mom.” Izuku stood up and took a few steps until standing beside his bed where the action was taking place. “Yeah,” he continued as he slowly stroked his dick. “I'm here studying with Todoroki and Kachaan...Yeah. We have a test tomorrow….I'll like that,” he continued on the phone and gestured Todoroki to move a bit lower on the bed to give Izuku some room. “We can make katsudon together while I'm there to visit.”

Izuku swinged his right leg over Katsuki and took advantage of Katsuki's open mouth to place his hard dick inside it. Katsuki took it in with a twirl of his wet tongue before Izuku lowered his hips for Katsuki to take it in slowly.

“It's math we're studying,” Izuku told his mother over the phone with his eyes closed and fucking Katsuki's mouth. “But thanks to Kachaan I'm confident we'll pass.” Izuku stroked Katsuki's blonde hair. He could feel Todoroki's forehead rest on Izuku's arched back.

If only Izuku's mom knew what was really going on behind the other side of the line. “Okay. I'll see you Saturday. Love you, mom.” Izuku hanged up. Then felt a sudden increase of movement behind him before a groan escaped both Todoroki's and Katsuki's lips.

“Let me fuck Kachaan,” Izuku said and looked down an Katsuki who was taking in his dick so well. Todoroki slipped off Katsuki and dropped next to Katsuki.

It felt dominating to say the least. Having Katsuki, the guy who once bullied Izuku now be in the hands of Izuku, was true victory. Izuku couldn't get enough of him. Katsuki was the essence of passion and living being of fire. He was fucking warm inside and Izuku loved it.

“You feel so good,” Izuku moaned in his ear. “If only our roles were reversed would I have loved to fill you in to the brink so you could carry my own babies.”

“F-fuuuck Deku ah,” Katsuki gasped. “I'll fucking kill you.”

“I'll be waiting.”

__________

After the aftermath of heated sex between Todoroki and Katsuki, there was not much space to share the same bed. So Katsuki had not much choice but to leave to his bedroom as Todoroki was in his rut and Izuku was to be the one to help him. Bless him, Katsuki was exhausted and satisfied.

“My heat is in a few days,” Izuku said before Katsuki left, causing him to stop.

“What about it?” Katsuki said.

Izuku turned to Todoroki who was watching him as well. “I won't drink any suppressants and won't put any scent blockers. I'll be going to class that day.”

“What?” Both of the alphas said.

“What are you thinking?” Katsuki said.

“I want to do it in the cafeteria,” Izuku said.

Katsuki bursted out laughing. “Nice one. But you won't.” Katsuki turned serious. “You'll only be rubbing your name in the mud and maybe get expelled. Hell, even ruining your chances of becoming prohero.”

“Not if one of the teachers also gets aroused as well,” said Izuku.

“Hey,” Todoroki spoke up. “You're getting too confident on your scent. You know very well it's distracting and arousing. Many alphas will fight to get you.”

“I don't care. You'll fight them while Mirio, Tamaki or any of you two fucks me in front of everyone. Besides, not all alphas are going to react but I know Azawai will.”

“What makes you so sure,” asked Katsuki.

“Because I tried it once and I saw the way he got turned on before walking away.”

“This is stupid, Deku. Stupid. Are you hearing yourself?” Katsuki said. “What if one of them gets their disgusting teeth on your scent gland? Huh?”

“Then you'll have to hurry. I'm doing it whether you like it or not,” Izuku said. “It's your fault having a great idea and it's your fault for not doing anything about it.”

__________

Monday came off to an interesting start. Izuku did it. Just as he told Todoroki and Katsuki last Tuesday. The students from the cafeteria exploded in whispers, gasps, yelps and frantic shouts of shock as the overwhelming scent of omega in heat exploded through the entire room.

“D-deku!” Uraraka yelled in horror as she stood back and watched Izuku bend over on the table as he was being fucked by an alpha obviously not from in Class 1A or 1B class. Not even in the group of alphas he was fucking with. It was another teacher with a typical quirk, having the ability to grow out bones from his body, caging both of them in.

“Leave Midoriya alone!” yelled Lida

It didn't take much after when Katsuki came exploding nearby and taking off the bone alpha away from Izuku. Nor did much time take for Katsuki to grow overwhelmed by Izuku's scent. He's never been so blinded by lust that he didn't realize how much he had began to thrust his dick into Izuku in front of his classmates who began to turn to the several alphas ready to take Izuku as theirs.

“K-kachaan,” Izuku moaned.

“Why are you so stubborn?” Katsuki whispered to him as chaos ensued around them.

“Get off him!” Uraraka and Momo screamed at Katsuki but were thrown back by his quirk. There was no stopping Katsuki as he licked and sucked on the scent gland of Izuku. Izuku turned to the side to look at Katsuki and smiled seductively like if Izuku was expecting something.

“He's mine,” Todoroki said, hand reaching behind Katsuki's hand to freeze him but stopped abruptly with the grey scarf of Mr. Azawai and the loud cry of pain and pleasure exploding from Izuku's lips. Katsuki groaned as he bit onto Izuku's scent gland, marking him as his and no one was going to dare do anything about it. Izuku was his and would not stop until Izuku's heat had subsided. Izuku's back arched and with his left hand he grabbed a fist of Katsuki's hair. His right hand gripped the hand that was stroking his dick.

If Izuku wanted to get fucked in the cafeteria, then Katsuki would mark him to claim him as his and no one else. Just as Izuku wanted all along. Just as Izuku had planned all along.

“My alpha.”

A bit too overboard but oh well. Hope you enjoyed;)
