Chapter Text
Barry was not surprised when Bruce walked into the bat cave with a tiny shivering pup in his arms. Besides, he would love the pup even if wasn’t his by blood. He just hoped Dick didn’t mind having a young sibling.

At first it had been quite the harrowing experience introducing Jason when Bruce walked into the Batcave with a tiny pup shivering in his arms. The Flash had just returned from a mission and the omega was on pins and needles from the stress and was trying to relax in his nest.
Barry had been sleeping in his nest curled around Dick, so when the smell of someone not their pack reached his nose, he let out a clear warning growl. It made Bruce stop in his tracks, the Alpha listening to the tone the head Omega was using.
“Barry,—-“ The Alpha crooned softly trying to make his scent as calming and soothing as possible as he held the tiny shivering pup even closer. Dick let out a whine as he scented the older Omega’s neck, trying to settle his adopted mother down. With a chuff Barry did relax as he opened his eyes to see what his mate had brought home.
His eyes darted towards the pup in his mate’s powerful arms, eying the pup curiously. He didn’t realize he was still growling until Dick brought it up. “ Mama stop growling please.” The young teen huffed not liking to see his mother upset.
“Stressful mission?” Bruce asked softly watching his mate slowly unfurl from his protective stance around their older pup. The blonde speedster gave a nod as he softened his gaze. “ Another one?” Barry asked as he looked the puppy over. He had shocks of black hair with a streak of white that stuck to his forehead. He looked a lot like Bruce it was uncanny.
“Found him trying to jack the wheels off the Batmobile.” Bruce let a smile quirk at his lips at Barry’s astonished reaction. “ Are you serious?” The Omega’s eyebrows shot up in amazement as he continued to look at the kid. He had to be no older then six. His heart breaking for the little one as he finally began to put out soothing omega pheromones and chirped softly at the kid.
Jason’s eyes opened a bit, briefly revealing the brilliant dark brown, he could vaguely see the man would become his new omega, his new mama. He chirped weakly back, distressed by being moved from Bruce’s arms to Barry’s who wrapped a blanket around the kid.
“You know I’m not letting you bring this kid to the adoption agency.” Barry huffed as he lifted his shirt to let the pup nurse from him, letting out a pleased hum as Jason suckled eagerly. Poor kid was much to skinny for his age.
“That’s how you got me,” Dick gave his mama and pops the biggest shit eating grin as he watched his new sibling with curiosity.
“So—-your up for being a big brother Dick?” Barry ruffled the younger Omega’s hair. “ I’m up for anything!” Dick puffed his chest out. “Jason is going to need a lot. But will it be worth it.” Bruce had let Alfred know to get another set of supplies ready for the new addition to their pack.
“Good, because I got a feeling Jason is going to be a handful.” Barry purred nuzzling the top of his new son’s head.

“Jason get down from the ceiling!” Barry all but had a heart attack one morning as he watched said pup currently eight years old climbing the curtains like his brother showed him how.
“Mama look no hands!” Jason jumped from said curtain to the chandelier as Barry zipped around in sheer panic mode.
“Just another usual Tuseday morning.” Alfred sighed as he took a sip of his tea, not flinching at all the sound of Barry yelling and Dick laughing his ass off.
