Tony
Bucky wakes to fingers running through his hair, for a moment he lets the dream he's having linger, forgets the pain and horror he has endured and lets himself drift in this limbo of softness.
But he has to wake eventually and slowly lets his eyes drift open.
For a moment he does not remember where he is other than a hospital, for a moment there is only Steve, just recovered from an illness and smiling sweetly at him.
"Stevie." He whispers.
"Hey, Bucky, how'd you sleep?" Steve asks.
Bucky blinks at him as he lifts his head from the mattress, a cold voice at the back of his mind questions why the Omega is asking such a question.
Bucky shrugs, he's rested, ready for his mission, nothing more matters.
The Omega frowns but gives a nod, "Alright, are you hungry, I think Tony's bringing burgers."
The Soldier frowns, he does not know who Tony is, does not know if the other is a threat and he does not want them near his Omega until he's sure they will not hurt what is his to protect.
Sam looks up from his book as the Soldier stands from his chair to move by the door.
"Oh crap." Sam says and then he's moving as Steve sits up and the Soldier hauls the newcomer into the room.
"Hey!" The small Omega screeches and the Soldier pauses but does not loosen his grip.
"Bucky!" Steve yells, "Let him go!"
The Soldier looks at his Mate, hears the panic and fear in his voice and something clicks inside him and his grip loosens, instincts shifting and accepting.
His Omega has claimed this Omega as his, his child and a good Alpha does not deny their Omega. A good Alpha accepts their Omegas decisions, especially involving children regardless of whether they have sired those children or not, there have been many Omegas known to have taken in orphans of War, most times at the cost of their Alphas abandoning them but a good Alpha will allow their Omega their children, blood or not.
The Soldier may not be a good Alpha but he wants to be.
He scents the new Omega and adds them to their Mission, they are his to protect now just as much as his Omega is.
Bucky blinks as he watches his Omega drag the other Omega to sit next to him, coddling him slightly, fussing over his eating and sleeping and before the dark haired Omega knew what was happening Steve was pulling him down to rest on his shoulder, tucking his head beneath his and humming to send him off into a nap.
Bucky approached slowly, Sam watching cautiously as he did, prepared to protect the two Omegas from him, Bucky realized and part of him was glad.
Bucky let his hands card through the dark haired Omega's hair, soothing the fussing that they were doing, likely a nightmare.
"I wanted a son." Bucky said softly as his eyes met Steve's.
There was pain there, something secret and buried, Bucky wanted to ask but not now, not here.
Steve tucked the other Omega closer.
"Yeah." Steve said softly.
Bucky pressed his hand to the side of Steve's face to make him look at him.
"What's his name?"
There was surprise in Steve's eyes but he smiled, relief making him relax as though he thought he'd have to choose between the Omega child he'd adopted and Bucky, like he'd expected Bucky to forget their agreement to adopt when they came home.
It had taken too long to get home but Bucky would not forget his promises to his Mate, not even Hydra could take those promises that he'd made the Omega and their children.
"Tony Stark." Steve said softly, burying his nose in the Omega's hair.
Something in his voice made Bucky pause, but his Omega was falling asleep as well, he'd have to find out how many other children his Omega had adopted later.

A/n: i intend to have one chapter for each of the Avengers as Bucky meets them and discovers his children because Steve adopted them and that means that Bucky does to because he's always followed Steve.
Tony first because i wanted Tony to be sneaking food into the hospital only he's also maybe avoiding board meetings and Pepper yelling at him for not sleeping and Steve can tell and just kind of does a mom type thing where he gets the kid still and calm and then boom, out like a light.
For once i am not marking a story as complete, i will try to post in a timely manner but i write as i'm inspired so i can't guarantee that.
My apologies for the possible wait in advance.
