Izuku Bakugou opened his eyes to a horrible sight.
Both of his children, tied up and chained to a wall, unconscious.
His omega instinct caused him to immediately reach out, only to realize his hands were also chained. He tried to use One for All, to find that the chains were quirk-cancelling. Fuck.
He thrashed around, observing the room.
It seemed to be in some sort of bar, as there was a shelf with empty wine bottles and glasses behind the counter his children were chained to.
The noise of the chains woke up his 16-year old daughter, Kiara. Her ruby eyes immediately went wide and she faced her dam, who’s eyes were wet.
“Ma? Where are we? What happened? Where’s father?” She questioned.
“I don’t know baby,” Izuku replied, despite the itching in his throat, “I only see us three here, and there aren’t any more chains, or hooks on the walls for more. Whoever took us, only wanted us three, not your sire. But don’t panic sweetheart. I know that Kacchan is probably ripping the city apart trying to find us.”
“If only I wasn’t quirkless,” his daughter muttered, “I could probably help. But now, I'm just useless.”
Right. Izuku always had that lingering fear that one of his children would be quirkless. It was one of the reasons he was afraid for children. But thanks to his mate, he regained his confidence. When his first born was determined quirkless, Izuku had locked himself in the bedroom, avoiding his daughter for a week. Only after much consultation from his husband and forgiveness from his daughter did he come out.
While deep in his thoughts, his eldest daughter rattled her own chains and woke up her 6 year old brother Inaro, and explained the situation. Who, thankfully, had a quirk. He had gotten his sire’s explosions, much to the man’s joy.
“How exciting..” A voice rumbled throughout the room. A voice that Izuku recognized all too well.
“All For One” He growled. A stinging pain shot through his stomach, and he doubled over, causing the villain to laugh. It’s been happening for the past week or two, and he didn’t know why.
“How pathetic. A horrible dam, aren’t you? You couldn’t even protect your own children in the ‘safety’ of your home. Neither could that pathetic alpha. Honestly, the way he’s storming through the city right now truly does make him look like a villain.”
“DON’T TALK OF MY SIRE THAT WAY!” Kiara shouted, eyes glowing red. Izuku shot her a warning glare, silently telling her to keep her mouth shut.
Through the darkness of the room, All for One emerged. Still with his ugly messed up face, though with a new scar from Katsuki during one of their recent battles, (Katsuki got a nice reward from Izuku that night).
“I found something out when we had our last encounter. During that time, I could tell you were having some...trouble keeping up with your mate and the rest of your pack. Honestly, I don’t know how someone so dense could be the number one hero” The beta said, walking to Izuku and lifting his chin with a finger. In return, Izuku snapped at him, an omega growl vibrating deep in his throat. It wasn’t as scary as an alpha’s, especially a dominant alpha like Katsuki, but it gave the clear sign to back off.
All for one only chuckled and turned towards the children. Kiara immediately dragged herself as much as she could, which wasn’t very far, and attempted to cover her sibling who was trembling in fear.
“So, you tell me children” All for One said, a smirk on his face, “what will your dam be having? A boy or a girl?”
Izuku’s eyes widened, as did his children’s. Both kids looked at their mind.
“Ma? Are you…?”
But Izuku couldn’t respond. Pregnant?! How could he not think of that?! All the signs these past two weeks, since his and Katsuki’s night alone. Even Katsuki had noticed the changes! He had told Izuku that his scent seemed sweeter! His stomach had been acting up, and he had been craving grilled cheese with mayonnaise for the past two days (which he did indeed eat, even though he wasn't allowed any kisses for the 3 hours that followed.)
All for One also seemed surprised and turned to Izuku with a sh!t-eating grin on his face.
“So you didn’t know either?! How convenient! Imagine! Don’t worry, at least you won’t have to tell your mate. Since by the time you see him again, there won’t be anything left of the brat.”
Izuku’s eyes filled with fear, and he squirmed around, trying to break free as All for One laughed and took a step closer. Kiara and Inaro screamed and pleaded for him to stop. He ignored them.
He stalked closer, until - BOOM!
An explosion broke the wall, causing pieces to fly everywhere. When the debris and dust cleared, one tall, muscular, and blond alpha stood, panting, red eyes gleaming. A deep growl resonated in his chest and he pounced at the beta male, sending both to the floor.
A blur of black and blond tumbled and rolled around the floor, as the pro heroes Red Riot, Uravity, Frostflame, and Chargebolt ran in and started untying the hostages.
Kiara and Imano immediately ran out with their parents' friends but Izuku lingered near the broken wall, whimpering and shifting on each foot. His mate was inside, but after finding out he was pregnant, he was too afraid to help. Only when pulled by Red Riot and Uravity did he reluctantly get to the ambulance.
-----------------
After a couple of hours, the family of four finally made it back home, where their sire immediately rushed them all to the nest and scented all of them. He kept muttereing under his breath how much of a horrible alpha he was, not even able to protect his mate and pups.
Izuku put a hand on his cheek, which made him stop and look up, allowing Izuku to see the tears in his eyes.
“You did good, Kacchan.” He praised. His pups nodded in agreement.
“No I fking didn’t. You got captured. He fking touched you and my pups. I failed.” He said, averting his eyes.
“No. He didn’t hurt any of us. All of us were fine. And we’ll continue to do so. All 5 of us.”
“Izuku, I love you, but you just messed up the simplest thing,” Katsuki said, chuckling, “there’s 4 of us, not five you idiot.”
Izuku gave a knowing look to his kids, who grinned at each other before pouncing on their sire.
“Well, how many do you want papa?” Kiara said, smirking the same way her father does.
“Yeah dad? 5, 6 or maybe even 7!” Imano said laughing.
Katsuki looked at both of them in utter confusion. Then, he leaned up on his elbows and looked at his mate. The green haired omega was looking at his stomach, before lifting his head. Green eyes met with red and Izuku blushed before looking down and rubbing his stomach once more.
Like a switch being turned on, Katsuki’s face suddenly lit up in realization.
“Izuku-baby-are-could...are you pregnant?” He asked, his voice wavering.
The children that sat atop his chest grinned down at him, while his blushing mate gave two small nods.
Katsuki jumped up and grabbed both of his kids before pouncing on the bed and showering his mate in kisses, ignoring his pups’ remarks. He grabbed both sides of his omega’s face and pulled him in for a kiss on the lips, gaining a gag from his son and a whoop from his daughter.
He pulled away panting and placed one of each of his family’s hands on his mate’s womb.
“However many there are, we’ll be there together.”
