(Smut warning)
Izuku POV:

Teruko decided to stay for the rest of Izuku's heat, ignoring Izuku's demands for her to go home and that he was fine. Teruko remembered the first time she experienced a heat after getting her soulmark, and she refused to leave her friend alone as he endured the same hellish pain she went through.

And it truly was hellish.

Izuku was locked in his bedroom, but he couldn't see how it was at all necessary. He couldn't imagine himself being able to get to the door let alone find Katsuki. Every minute that slowly ticked off his clock felt like hours, and with every second the burning sensation that was consuming him only grew more painful. What had started as a dull aching and warm sensation in the bottom of his abdomen expanded into bullets and knives and being set on fire all at once.

Though, Izuku would have much preferred real bullets and knives to the pain he was experiencing. At least that way it would be over in a mere few hours at most. Whereas his heat will last a week at the very least, and it's barely been a day. But Izuku would rather die than do a majority of things, so it wasn't something out of the ordinary.

What was unusual was his inability to gain control over his body. With every new heat wave that struck him his vision blurred and his pain increased tenfold. But what terrified Izuku the most was the lack of control he had over his own movements. Every time a heat wave hit him he lost complete control over himself, thinking and doing things he would have never even considered in a sound state of mind no matter how intense his pain was. He found he couldn't stop thinking about his soulmates, his alphas, and all the things they could do to him. Izuku wouldn't admit it even if he was on his deathbed, but the idea of his alphas knotting him and filling him with their pups was what had driven him to cum since his heat had started.

Somewhere in the back of his mind he remembered his boyfriend and knew it was wrong of him to be getting off on the idea of other alphas, but he couldn't find it in him to care. Aito was the only alpha he had ever been romantically close to, yet in all of his previous heats he shied away from him, avoiding him even in his vulnerable state. As far as his lust-driven brain was concerned, Aito didn't exist.

But between each wave of his heat, in the few minutes he had of peace when he could go back to controlling his own movements, Izuku was blessed with the comfort of his alphas' words. Try as he might to hate the communication, when his alphas sent him messages of comfort he revelled in it. He spent those rare moments reading over every message they would send, their words calming him down as he prepares for the next painful wave.

Hold on baby, it'll be over soon.

You're doing so well.

We're so proud of you.

You're so strong, just a little bit longer.

Had Izuku not been in heat he would have found the reassurances somewhat patronising, but in the burning pain he was currently in he was infinitely grateful. His omegan instincts made him croon at the alphas' praises, treating them like a lifeline written on his skin. He may not want soulmates, nor does he trust he'll be alive to even meet Shoto, but their words of encouragement ricocheted through his heart and put him at ease, making his heat slightly more bearable.

Stupid omegan instincts, driving me crazy.

Again, Izuku reminded himself of Aito, trying to convince himself in this rare moment of clarity that it was Aito that he wanted. But the thought of Aito being the alpha to comfort him during his heat made him shiver in disgust. When he wasn't in heat he could swear he loved Aito, sometimes he could even convince himself that Aito loved him back, but his omega knew better. Maybe it was the soulmate bond that made him want his soulmates, or maybe it was his omegan instincts that wanted the alphas destined for him, but in the torture of heat that now consumed him Izuku only wanted two alphas by his side.
