The evening came and Ochako and Mina as well as Tenya and Tetsutetsu came over, they wanted to check up on Katsuki as well. Aizawa looked after him a couple of times too.
Katsuki woke up later again, when Rikido brought some food over. “You should really eat” Tenya advised him. He gave the plate to Izuku.
“He’s right” Izuku sat next to Katsuki on the bed. The omega was still burning hot, he was sweating through the tank top and boxer shorts he wore. Katsuki lifted himself up a bit and leaned against Izuku.
“If you say so, my alpha” he slurred again. And then it started, cramps started to hit Katsuki and an incredibly spicy scent was coming off of him. He leaned over to Izuku after the cramp released. “Please, prime alpha! I am in so much pain!” He moved higher and pressed his lips against Izuku’s.
“FUCK!” Ochako exclaimed. “You need to get out! He’s going into heat!”
“What? Wasn’t he supposed to enter heat at the end of next week? Even for an early heat, this is too early!” Mina sounded panicked.
“I don’t know! You alphas need to go!” Ochako tried to usher the alphas out of the room, but it was too late.
Eijiro was next to the bed in seconds he grabbed Izuku by the throat. “He’s my omega! Stay away from him!”
Izuku roared and pushed Eijiro back. “As if you could challenge me!” his voice was incredibly deep.
Tetsutetsu, Tenya and Rikido tried to hold them back, but more of Katsuki’s spicy stench was getting on their nerves.
Katsuki was lying in the bed, he started to cry. “No, please alphas! Don’t fight!” Ochako was with him in a second and put a hand over his mouth.
“Stop talking!” She froze, when she saw the amounts of slick coming out of him. She gulped when she turned around, the alphas were quiet … too quiet for her liking.
All five of them stared at Katsuki. Even Tetsutetsu, Tenya and Rikido had an absolutely predatory look on their faces, they were all focused on the omega.
The worst thing had happened. Katsuki’s heat had started their ruts. “Omega … you’re mine” Izuku growled. He stalked closer to the bed, but suddenly, Denki charged at him and shocked him. Hanta used his tape to temporarily block the other alphas.
“We need to get out of here!” he screamed.
Ochako activated her quirk and took Katsuki in her arms. The omega was fidgeting, he wanted to his alphas.
They made it out barely because as soon as Hanta’s focus wasn’t on the tape any more, they managed to break free. Hanta slammed the door in their faces and sealed it quickly with tape. He followed after the others.
They ran over the place, they looked for the teachers, but unfortunately, they ran into Shoto and Hitoshi first. “Hey, what’s going … on” Shoto asked, but then he smelled Katsuki’s scent. He started to growl.
“Fucking hell! This can’t be true.” Denki whined. They hightailed out of there, while Mina splashed some acid in their direction. Katsuki’s heat scent was so strong by now, that it had triggered their ruts immediately.
They made it to the campfire area. “We need help!” Mina yelled. Aizawa looked up and he saw the group of omegas and betas running towards them, followed by Shoto and Hitoshi who were hunting them. Further behind were the other five alphas, quickly catching up.
“What the hell is going on?” Shota and Hizashi sprang into action immediately.
“Katsuki went into heat and this triggered their ruts!” Ochako screamed over the roar of the alphas.
Aizawa paled. “This can’t be true, this is a nightmare!” he muttered under his breath. “We need to get him out of here!”
The group stopped next to Aizawa and Present Mic. The DJ covered his nose immediately. It wasn’t as bad for him as for the other alphas since he was mated, but it was still a very strong scent.
They changed directions and headed for the main building. The other betas and omegas followed them and tried to fend off the alphas. They had to bring not only Katsuki to safety but the other omegas too. Since none of them were mated the alphas in their ruts would target them too. Besides, the ruts of an alpha could trigger the heats of omegas. This would be the worst case scenario, not that this was currently better.
Mezo, Jurota and Juzo tried to hold off the alphas as well, they had covered their noses but it was difficult.
Izuku jumped with full cowl and he hit Ochako, she lost Katsuki and hit the ground, she released her quirk. Izuku grabbed Katsuki and pressed him on the ground.
Katsuki was moaning and wrapped his arms around Izuku’s neck. “My alpha!” He smiled and kissed him again.
But suddenly, Ian ripped Izuku off of Katsuki. He picked the omega up. “No, my alpha!” Katsuki whined.
“Hush now, omega!” Ian said in a firm voice. Katsuki still squirmed in his arms, but he kept quiet.
Jesper and Kairi helped to fend the rutting alphas off and collected they made it to the main building. Vlad King and Hound Dog stayed outside since they weren’t mated. It was easier for them to withstand Katsuki, since he was so much younger, but they didn’t want to risk it.
They barricaded the door, Ian had still Katsuki in his arms, Jesper and Kairi checked the windows and made sure the alphas couldn’t break through them.
“This is just the worst!” Aizawa grumbled. “Why is it this early? That’s a week too soon!”
Katsuki moved in Ian’s arms. “Please alpha! It hurts so much! Help me!” he pleaded. “I was a good omega! Please make it stop!” He reached up and cupped Ian’s cheek with his hand. He seemed to loose his lucidity pretty quickly now.
Ian grimaced and looked a bit grossed out. “Uh, no thanks. C-Can someone take him? Please?”
Denki came over and took Katsuki from him. “C’mon Kacchan, lets sit over there” he brought him to one of the couches. Katsuki complained heavily.
“No, please alpha! I am a good omega, please! I promise! I am sorry if I did something bad, but please!” he cried. He grabbed Ian’s shirt and didn’t want to let the prime alpha go. Carefully, Ian peeled his hands off.
“It’s not that, I just don’t like all that omega stuff …” Ian grimaced when he realized his arm was covered in Katsuki’s slick, he stuck his tongue out and walked over to the sink to wash it off. He needed all his self control to not start to retch.
Katsuki whined more and he shifted in Denki’s arms. “No, omega, let me go! I want to my alphas!” his voice got louder.
Denki blushed at that, some of the others looked at him with quizzical looks, but didn’t question it for the moment.
Aizawa crouched next to Katsuki. “Hey, I need you to calm down. I know it is hard but you have to try.”
Kairi came back down, followed by Jesper. “Okay, all windows are secured. I’ll make my way outside now.” She scrunched her nose. “Yuck, I never liked omega heats, the stench is abhorrent” she muttered.
Jesper sighed. “True.” They then left quickly through the door. They dragged Present Mic with them outside.
“T-they don’t like me?” Katsuki cried. Aizawa sighed.
“No, they like you, but they are both mated.” He tried to calm him down.
“God, it hurts so much! I want my alphas!” he rubbed his legs together. The girls squeaked and turned around when his hand wandered to his crotch.
“Uh, we should bring him upstairs to give him some privacy. Kaminari, are you staying with him?”
“S-sure” he picked Katsuki up and together they brought him to the upstairs room. Denki stayed with him, while Aizawa went down again to get some towels and water. Ian had left too, to hold off the rutting alphas.
