Tony 2
Bucky doesn't like Tony's lab, it's cold and it reminds him of the Chair, he doesn't like being in Tony's lab without Steve next to him, but Steve isn't available to be here, the Omega has been put on bed rest by Bucky after an Avengers call and J.A.R.V.I.S. had informed Bucky that Tony had not left his lab in nearly three days.
Bucky forced himself to look around the lab, forced himself to take in the differences, there was life in this lab that hadn't been allowed in Hydra's. It was cluttered and disorganized and loud, music blaring and echoing off the walls and sending vibrations through the metal scrap on the floor and tables.
Tony was dirty and sweaty, talking a mile a minute to nobody, or at least Bucky had thought it was nobody until he saw a little robot bob an arm, which the young Bucky, the one that had dragged his Omega to a Stark Expo, would have absolutely loved.
Bucky as he was was still impressed but he'd lost that boyish delight that he'd had at the Expo so long ago.
"Barnes!" Tony cried out as he saw him, "Here for your new arm? Come on."
Bucky let the boy drag him to a bench, metal but not cold and watched the Omega run and grab something off of a desk or counter.
The excited and tired Omega talked about things that Bucky didn't quite grasp as he connected the arm to the metal that had been left on his shoulder.
Tony tinkered with it and hit the arm with a wrench a few times, which alarmed Bucky because really?
"There that should do it, give it a whirl." Tony said, grinning at him brightly.
Bucky looked at his arm and told it to twist his wrist and listened to the sound of gears shifting as it did so.
For a moment Bucky was enchanted with the brilliance of technology that had allowed Tony to make this arm for him, as well as the intelligence of Tony to figure out how to reverse engineer the Hydra arm.
"It's just a proto type, I'll keep working until it's better and it'll be almost like a real arm." Tony babbled and Bucky frowned.
The arm was good, better than the Hydra arm, it was lighter and didn't pull on his shoulder so much, Bucky had a feeling that the lingering aches in his left side that had occured while he was still fitted with the Hydra arm would be a thing of the past, or at the very least less mind consuming.
But that didn't explain why Tony thought he was disappointed with it.
Then it occured to him, stupid Howard, Steve had always said that the man shouldn't be allowed children, and Stevie had thought everyone deserved the chance to have kids. But in Steve's eyes Howard had always been too much of a flirt, unable to make the sacrifices kids required.
Howard had known Steve was an Omega and Steve being Mated hadn't stopped the Alpha's flirting, Steve had said that Howard had promised to take care of him if he'd wanted, Steve hadn't and a nice punch to the jaw hadn't stopped Howard's attempts to get Steve into bed, the other Alpha's touches lingering just a tad too long to be appropriate, Bucky's promise to gut him if he ever tried to force anything had.
It was one of those things Steve had only ever told Bucky about, 'they don't need to know, I can handle it' he'd said, Bucky hadn't felt Steve should have to but had stepped back after his threat and while the flirtation remained any attempts at taking it further had stopped.
But as Tony babbled Bucky realized that Steve had been right, Howard didn't deserve kids, didn't deserve Tony.
"It's good." Bucky interrupted.
"What?" Tony blinked, face scrunching up in confusion.
"I like it, it's light and it doesn't pull." Bucky stretched his left arm out to the side and then up, he wasn't able to lift it completely above his head but it went far enough that Bucky could compensate for the lack if he needed to.
"I can fix that." Tony said, still sounding a little dazed.
"Alright, but first you need sleep." Bucky told him standing.
Tony opened his mouth to protest and was interrupted by a yawn.
"Come on." Bucky said softly as he caught Tony as he finally begun crashing as his movement stalled.
Bucky lifted the Omega easily into his arms as the man stumbled, the younger wrapping his legs around Bucky's waist and laying his head on his right shoulder.
"Steve's gonna be jealous I got my legs around you." Tony slurred and Bucky felt inexplicable anger that that was Tony's first thought, that he was causing problems for him and Steve.
"Steve knows that all I have belongs to him." Bucky returned, because it was true, no matter how many times he'd escorted a pair of ladies around Steve had always known who Bucky was coming home to, and most of those Omega girls were more interested in each other than the Alpha holding their hands.
Steve got it, hadn't cared for the rumours about Bucky stepping out on him because he couldn't have a baby, not when Bucky held him so tenderly each time he lost theirs, not when Steve knew the truth, that Bucky was with him no matter what, kids or no.
"That's sweet, I want that." Tony mumbled.
"You have what's her name?" Bucky frowned because he was sure she'd been introduced, or at least Bucky had threatened her with a fate worse than death if she hurt his kid.
"Pepper." Tony sighed, "She deserves better than a used up Omega like me."
Bucky felt his stomach twist and not in a good way.
How many times had Steve said something similar after he lost a child, how many years had it taken to convince him that Bucky just wanted him, no matter what, till they were both old and grey?
Bucky shifted his hold so he could pet Tony's hair.
"She chose you though, doesn't matter what you think she deserves, only what she decides to have." Bucky told him gently.
He once yelled something similar to Steve, 'I don't care what you think I deserve, I want you, Steve.' He'd said and then he'd held Steve until the tears stopped and had carried Steve to bed before scrubbing the blood from the tub yet again before he joined Steve in bed, holding him tight as he woke halfway through the night to cry over their most recent loss.
"I can't give her babies." Tony whispered, hiding his face, "Doctors say it'll strain my heart too much, that it'd kill me."
Bucky felt himself stiffen, he'd heard the same about Steve, it had been part of his reasons for demanding that they never try for children, but it hadn't mattered in the end, Steve always ended up pregnant, even outside of real Heats and his body always ended it too soon.
"Way I see it, if it's something you really want you can adopt, or Steve says there are people that'll do the carrying for you." Bucky told him.
Tony pulled back to look at Bucky's face.
"Is that what you and Steve are looking at doing?" Tony asked and Bucky almost frowned before remembering that no one had noticed Steve was an Omega yet.
Bucky shrugged in answer, he was honestly still getting used to the kids they had adopted already, he wasn't sure how he'd handle a baby.
Oh, god, a baby, a tiny little fragile thing that was so easily broken.
But also, a part of Bucky whispered, a little thing that was half him, half Steve.
He wanted, Bucky realized, he wanted to give Steve a baby, wanted to see him grow with it, see him stitching a blanket for their arrival, Bucky's heart ached for it in the same way he feared it, he didn't think he could watch Steve lose another baby, not again, not after all they had been through, it wouldn't be fair.
Tony looked at him and then settled back on his shoulder as Bucky stepped into the elevator.
"I think you'd be good dads." Tony whispered as he went boneless in Bucky's arms as he began falling asleep.
Bucky set his cheek against Tony's hair as the elevator made it's way to Tony's floor.
"I think we wouldn't be so bad at it." Bucky agreed, they weren't doing so bad with the ones they had already.
Bucky carried a sleeping Tony into the room he shared with Pepper and made a call to the Alpha, staying until she arrived from the New York office and then he left her to comfort her Omega before heading to hold his own.
He didn't feel ready to bring up trying for a baby, not yet, but Bucky thought as he climbed into the bed he shared with Steve and took the Omega in his arms, if it happened it happened, there were better doctors now and Steve had told him that the last one might have lived if he had noticed before he'd gone on missions.
Bucky tucked his nose into his Mate's hair and let himself dream about a little boy, or perhaps a girl, with Stevie's blue eyes and his own dark hair, he let himself dream about Tony showing her how to tinker with bright adoring eyes, dreamed of Bruce teaching him Yoga with patience and the Hulk's great hand holding him gently as he rocked them to sleep. He dreamed of Natasha stealing them for practice with Sam, of Clint teaching them how to crawl through the vents, of Thor taking them flying with Mjolnir.
Bucky hummed in his sleep as he scented his Mate, he frowned slightly at the notes of sweetness he found, Steve shouldn't be sneaking chocolate when he was recovering.

A/n: i thought about having one more chapter where Bucky realizes Steve is Pregnant but decided not to, this is the Avengers' story and i wanted them to be all there was.
On a side note: Steve is not eating chocolate in bed so take that how you will.
Tony not being able to have children is a result of the Arc Reactor in his chest, his lungs wouldn't be able to take the pressure of a baby growing and his heart probably wouldn't be able to take the strain of pregnancy. Basically he still has the possiblity but it'd risk his life unnecessarily to get pregnant.
There is also the bias that Female Alpha shouldn't carry children, mostly prejudice and tradition, with this in mind it's also a possibility that Tony provides the egg and Pepper the Sperm and they do a fertility treatment and Pepper carries the baby because Female Alphas still have wombs they just aren't really thought of in terms of reproduction, that's what Omegas and Beta Females are for.
With that in mind Natasha's womb is still present, the Red Room was traditionalist and therefore considered a Female Alpha's womb useless but not enough to remove it, which means she and Sam may have babies in the future.
