Chapter Text
Shouta Aizawa was never the type to forget his rut. Normally he can see the signs. Like irritability, possessiveness, hornyness. His rut was always the same time every other month…except for this month.
It seems that after only a week or so of being with you, he was sent into an early rut. This would have been fine…if he wasn’t in the middle of helping Deku take down a villain. Poor Deku had to use black whip to tie him up. When the green haired pro hero showed up at the door with your alpha, you didn’t even get to ask what was happening before Shouta was on you.
He threw you over his shoulder, leaving the young hero standing in your doorway. He carried you into the bedroom and wasted no time stripping himself down.
“A–alpha!” You squeaked when he began to tear your blouse off of your body, popping the buttons in the process. “This is one of my favorite shirts!”
“Shhh, be a good girl omega” Shouta growled as he pulled down your skirt and panties. “Fuck omega, you look gorgeous like this”
“Alph–a…wait a minut–”
“Present omega” He demanded with a serious look on his face. You immediately lost control of your body. In a flash, you were face down, ass up. “See, you can be a good girl.” He said giving your ass a nice smack. You felt his fingers ghost over your slit.
“Shouta–” You were cut off by his thick fingers pumping into your warm, wet cunt.
“Be still omega” Shouta says moving his fingers faster and faster. As soon as he deemed you wet enough, he pushed his cock into your tight cunt. He didn’t give you time to process anything before he was slamming into you. His hands were holding on to your hips so tightly they were starting to bruise. It felt so good. You were on cloud nine. “Such a shit…you– fuck…you take my cock like such a good fucking girl.”
“Al–phaa…Fuck!” You moan, clawing at the sheets, trying to find anything to give you some leverage. You could feel his cock bullying every single one of your sweet spots. You couldn’t even form coherent thoughts.
After what seemed like your millionth orgasim, Shouta’s thrust began to become erratic and you could tell he was close. He came and knotted you so fast it had to have been some kind of record.
“Good…good girl” He says between panted kisses to your back
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hitoshi couldn’t sleep. He could get his mind off you and your sweet little frame. Why didn’t Shouta warn him about you? Your scent lingered in his room. It was just so…sweet…like candy or pies dams baked for their pups. For some reason it was so familiar to him. He shoved his face into the shirt he had stolen from your nest when you were taking a shower.
His right hand dipped into his boxers and wrapped around his leaking cock. He began to pump at the thought of you in those tiny little shorts you loved to wear around the house. He imagined you on your knees for him. So sweet and ready to please. He thought of how easy it would be to just tie you down and fuck you until you cried. “Fuck!” Hitoshi groans as he shoots thick ropes of cum into his boxers.
He had to fuck you. Having you bounce on his cock would just fix all of his problems. All the stress from being a pro hero would just melt away if he could be inside that sweet little cunt of yours. The only problem is that you were Shouta’s. He needed to find a way to convince the man who provides him with everything, to also share his omega. There was no way he would agree to that. He already lets Hitoshi crash there rent free and doesn’t complain when he eats all the food and doesn’t clean up after himself.
He stared up at the ceiling of his room. He had to know who you are. He pulled out his phone and texts the only other person he knows would give him anything.
Toshi
Hey Hiz, I have a question about Aizawa’s omega
Hiz
She"s cute isn’t she?
Toshi
Not the point. I need to know who she is. Name…origin…how the hell Aizawa found her
Hiz
Oooh planning something are we?
Toshi
…
Hiz
Her name is Y/n Yagi
Toshi
Wait…like All Might?
Hiz
Yep. Sweet little omega is the daughter of our former number one. Plot twist am I right?
Toshi
Thank you. That"s all I needed.
Y/n Yagi. No wonder you smelled so familiar.

Hitoshi didn’t have the best upbringing. The neighbors elected to ignore his screams on the days his father would come home drunk or his cries when his mother would overdose on their kitchen floor. Nobody ever gave a shit about him. Teachers, social workers, even his friends’ parents would ignore his bruises and cuts.
He was six. It was a Friday like any other. His father was gone and his mother told him to get lost. He was wandering in the forest behind the good 7/11, hoping maybe he could find some berries or something that he could eat.
“Don’t move!” He hears a feminine voice whisper from behind the bush he was currently ravishing. He looks up to see a small girl hiding. She pulled him behind the bush with her and held him tight. “There"s a man with a gun over there.” He looked over and sure enough, a man with a gun was frantically looking around just a few feet from where he was just standing. It was a miracle that he didn’t see him.
“Who is he?” Hitoshi whispers
“He was following me”
Hitoshi looked down at the girl who was holding him. She smelled sweet. It reminded him of the candy he would sneak from his friends’ houses.
“There you are, you fucking brat”
Both children look up to see the man standing over the bush. He grabs Hitoshi and drags him away from you. “NO! STOP! I’m-m sorry! I’ll come with you” You screamed as you tried to keep your hold on Hitoshi
“Shut the fuck up or I will kill you both!” The man says
Hitoshi was terrified. Of course this happens on the one day a week his parents let him out of the house. He closes his eyes and braces himself for a gun shot that never came. When he opened his eyes, he saw that there were roots and vines holding the gun just out of reach. The man let Hitoshi go and was pulled into the air.
Once the police showed up, Hitoshi found out that you were All Might’s daughter. After he spent the night at the police station he found out that you told your father you saw bruises on Hitoshi when you were hiding in the bush. The detectives took one look at him and called Social Services. The difference this time being he got to watch All Might arrest his parents on TV.
— All Might Saves Local Boy from Abusive Parents—
It was the hedline on every news station that week. If it wasn’t for you, he would have still been in the house, underfed, and beaten everyday. He probably wouldn’t have survived.
~~
Hitoshi had spent years moving from one shitty foster home to another. Once he was old enough, he applied for UA and vowed he would save people like your father had saved him. He worked his ass off to get into the Hero Course and to work for a good agency and here you were.
It was like fate for you to be back in his life again. He needed you.
~~~~~~~~~~~~~~~~~~~~
Your father was exhausted. He was trying to come to terms witht he fact that you are gone. Tsukauchi basically told him there was nothing he could do so now he sat in his backyard, missing you. It was…quiet. Normally you would be playing music, or singing or…something. Normally, when he would sit in the backyard, you would be with him, drawing or training your quirk. He tried to think about what he did so bad that you would levae him like this. He never claimed to be the best father but, he didn’t think he was terrible.
He pulled out his phone and called someone he hadn’t spoken to in years. Not since he put him in jail and especially not since he got out.
“Dave…we-uh…I need to talk to you.”
