Notes:

This is an unfinished WIP from my old FF.net days and I couldn't stop thinking about it since @Baibe mentioned it. I still need to edit Neighbors and work on Another Chance, so I can't say how often I'll update, but we'll see. I try my best.
I hope you'll enjoy this little, silly story:)

Chapter Text

Natasha Romanoff had made her peace with death.

It hadn’t come easily—peace never did, not for her—but in the end, as the wind howled in her ears and the cliff gave way beneath her feet, there had been a strange, quiet certainty. Her life, for all its blood and broken things, had meant something. The red in her ledger hadn’t vanished, not really—but it had balanced. For the first time, she hadn’t been running from it.

She had fallen knowing that. She had died knowing that. And that should have been the end.

But it wasn’t.

The first thing she remembered was breath. It tore into her lungs like something foreign, sharp and unwelcome, dragging her back into a body she hadn’t expected to feel again. Her heart stuttered, then slammed hard against her ribs, frantic and alive. Alive.

Natasha had lain there for a long time, unmoving, staring at nothing, trying to understand how there could still be anything to see.

Death had been quiet. Final.

This—this was wrong.

Her mind scrambled for logic, for reason. Steve. The Stones. The mission to return them. Something had changed. Something had broken the rules.

Her sacrifice.

The thought hit harder than the fall ever had.

Had it been undone?

Panic came then, cold and sharp, curling tight in her chest. If she was back—if she was back—then what about everyone else? What had it cost? What had been taken in exchange?

But the answers came, slowly, painfully, one by one.

Everyone was still there. The world hadn’t unraveled. The people she had died for were still alive.

Yelena was still alive. That was what broke her.

Not the impossible resurrection. Not the confusion, or the lingering echo of the fall. It was Yelena—real, breathing, stubbornly alive—that shattered whatever fragile composure Natasha had managed to hold onto.

She hadn’t allowed herself to hope for that. Not even in her final moments.

Some things had always been too much to ask for.

Everything had felt different after that.

Or maybe it was just her.

People spoke to her gently, like she might disappear if they weren’t careful. They watched her when they thought she wouldn’t notice. Clint couldn’t quite meet her eyes for too long, guilt and relief warring in equal measure. Steve carried something heavy in his silence, something he didn’t seem to know or want  to explain.

A routine examination, they’d said. Just to be sure everything was… stable. Functional. Whole.

Natasha had expected scars. Ghosts. Damage that couldn’t be undone.

Instead, Cho had gone quiet in that particular way doctors did when they were trying to find the right words for something that didn’t make sense.

“You’ve healed,” she had said finally. “Completely.”

Natasha had almost laughed at that. Completely wasn’t a word that had ever applied to her. But Cho hadn’t finished.

“There were… procedures done to you. Before. In the Red Room.”

Natasha’s body had gone still, every instinct sharpening. “I remember.”

Cho hesitated, then met her eyes. “They’re gone.”

The words didn’t land at first.

“They’re gone,” Cho repeated softly. “Natasha… your body has been restored. Fully.”

Restored. The word echoed, hollow and impossible.

And then—

“No.”

It came out sharper than she intended, edged with something close to anger. “No, that’s not—” She shook her head, pushing herself up, pacing like a caged thing. “That’s not how this works. You don’t just—fix that. You don’t just give it back.”

Cho didn’t argue. Which made it worse.

“You’re wrong,” Natasha said, quieter now, but no less fierce. “Run it again.”

“We did,” Cho replied gently.

Natasha let out a bitter, disbelieving breath, dragging a hand through her hair. “So what is this supposed to be? Some kind of… reward?”

The word felt wrong the moment it left her mouth.

A reward implied she had done something for it. But she hadn’t. She hadn’t jumped for this. She hadn’t sacrificed herself with some hidden hope tucked away in the back of her mind. She had done it because it was necessary. Because Clint deserved to go home. Because Yelena deserved a chance to live a life that wasn’t dictated by someone else’s cruelty. Because it was the right thing to do. That had been enough. It had always been enough.

And yet… Now there was this.

A possibility she had buried so deeply she’d convinced herself it had never existed. A life she had never allowed herself to imagine.

Natasha stood very still, the weight of it pressing in from all sides.

She could carry a child.

The thought was terrifying in its enormity. Fragile. Dangerous. It felt like something she could break just by acknowledging it. For so long, that choice had been taken from her—ripped away before she had ever been old enough to understand what it meant. It had been one more thing the Red Room had stolen, one more piece of her they had decided she didn’t deserve to keep.

And now— Now it had been given back.

Later, when she was alone, Natasha sat by the window and watched the world move on outside, unchanged and utterly different all at once.

Clint had his family.

Yelena had her life.

She had asked for nothing more than that. She would have been satisfied with that. But somehow, impossibly, she had been given more.

Natasha pressed a hand lightly against her abdomen, not quite daring to believe in what it represented.

A future. Not redemption. Not atonement. Something beyond that.

Something she had never thought she was allowed to have.

Her breath caught, just slightly.

And for the first time since she had returned, Natasha Romanoff didn’t feel like she was living on borrowed time.

She felt like she had been given a beginning.


A year had passed since Natasha had come back from the dead.

Long enough for the world to settle. Long enough for people, meaning Steve, to stop watching her like she might vanish again if they blinked. Long enough for the quiet to set in.

She wasn’t an active Avenger anymore. Not in the way she used to be.

The missions still happened—there were always missions—but Natasha had stepped back, deliberately, carefully, like someone testing unfamiliar ground. She stayed behind more often than not, working strategy, intelligence, coordination. The kind of work that kept her hands clean.

Cleaner, at least.

It was strange, at first. The stillness. The absence of constant urgency. No more waking up already braced for impact, already calculating exits and contingencies before her feet hit the floor.

Now there were mornings. Actual mornings.
Coffee that didn’t go cold because of an emergency call. Sunlight that lingered instead of being ignored. Time—too much time, some days.

Time to think. And she had been thinking about it for a year. The thought hadn’t faded the way she had expected it to. It hadn’t dulled or been pushed aside by something more practical, more urgent.

If anything, it had only grown sharper. Quieter, maybe—but heavier. More real.

Natasha wanted a child. Not in some abstract, hypothetical way. Not as a fleeting curiosity or a “what if” she could tuck away and forget about later.

She wanted it. She wanted to be a mother. The realization had come slowly, then all at once.
At first, it had been small things. The way her attention lingered when she passed families in the street. The way she found herself noticing details she never would have before—a toddler’s unsteady steps, the quiet exhaustion in a parent’s posture, the soft, absent-minded way someone brushed hair out of a child’s face.

Then it had become something else. Something intentional. She had the time now. The means.
The stability—at least as much as someone like her could ever claim to have. For once in her life, she wasn’t surviving. She was living. And the idea of building something instead of tearing things down—of creating a life instead of ending one—

It rooted itself deep. Natasha exhaled slowly, staring out at the city below, her reflection faint in the glass.

She had paid for her past. More than paid. She had given everything, without hesitation, without bargaining for something in return. And somehow, impossibly, she had been given another chance.

A life.

A future.

A choice.

This was a choice.

“I’m going to have a baby,” she murmured to the empty room.

Saying it out loud made it real in a way thinking it never could. It settled into her bones with a quiet kind of certainty. Not impulsive. Not reckless. Decided.

The how was the problem.

Natasha huffed a soft, humorless breath, pushing herself away from the window.

She didn’t have a partner. No boyfriend waiting in the wings, no quiet, steady relationship she could build something like this from. And the idea of dating—of sitting across from strangers, making small talk, pretending to be someone simpler, easier to understand—

It sounded like a special kind of torture.

Worse, it felt dishonest. Because this wasn’t about romance. It wasn’t even about love, not in the way most people meant it.

This was about a child. About her choice to become a mother.

And tying herself to someone—permanently, irrevocably—just to make that happen…

Natasha’s jaw tightened slightly. A child would bind them forever.

No matter what happened after. No matter if things fell apart, or never really came together in the first place. She had seen enough broken families to know exactly how complicated that could become.

There were other options. Clinical ones. Safe, controlled, detached. Logical. Natasha was good at logical.

And yet…

Her mind kept circling back to the same thought.
The same person. She stilled, her fingers curling slightly at her sides. It wasn’t logical.
If anything, it complicated things even more.

He was from another time. Another world, really. His sense of right and wrong, of duty, of what a family should look like—it was different. More rigid in some ways, even if he tried not to show it. Or maybe she was projecting. Maybe it was just easier to assume the answer would be no. Easier than asking.

Natasha let out a quiet breath, shaking her head at herself. What was she even supposed to say?

Hi, I respect you, trust you with my life, and also—would you be willing to father my child with no strings attached?

The absurdity of it almost made her laugh. Almost. Because beneath that was something else. Something she didn’t want to examine too closely.

Trust. Not just in what he could give, but in who he was. In who he would be… as a father.

That was the part that mattered. Not genetics. Not convenience. Him.

Natasha closed her eyes briefly, steadying herself.

She had faced worse conversations. Harder ones.
This shouldn’t feel like stepping off another cliff.

And yet… It did. Because this time, it wasn’t about saving the world. It was about building one. And for someone who had spent her entire life learning how to survive— That was a different kind of risk altogether.

No, there was only one logical solution.

A sperm bank.

Natasha nodded to herself as if she’d just completed a highly classified mission briefing instead of googling “how to have baby alone without emotional complications” at two in the morning.

It was efficient. Anonymous. No strings attached. No awkward conversations. No unexpected emotional entanglements. Just science, paperwork, and a disturbingly detailed catalog of men reduced to bullet points.

Perfect.

She knew people who had done it—couples, single women. It worked. No regrets. No drama. No… Steve-shaped complications.

Because this had nothing to do with anyone else.

This was her decision. And once Natasha Romanoff made a decision, that was it.

The clinic was clean. Quiet. Comforting, in a sterile, slightly-too-white kind of way. She had done everything right. Healthier food. No alcohol. Regular check-ups. Eggs frozen—she still wasn’t entirely over how surreal that conversation had been.

Now all that was left was choosing a donor.

Which, apparently, was where everything fell apart.
Natasha stared at the tablet in her hands, scrolling through profiles with the same intensity she used to reserve for enemy dossiers.

Donor 1472
Height: 185 cm. Eye color: blue. Advanced degree in engineering. Enjoys hiking and classical music.

“Of course you do,” she muttered.

Next.

Donor 2381
Medical student. Volunteers at animal shelters. Described by staff as ‘kind’ and ‘thoughtful’.

“What are you hiding?”

Next.

Donor 3105
Professional musician. Green eyes. ‘Great sense of humor.’

Natasha narrowed her eyes.

“That tells me nothing. What does that even mean? You laugh at your own jokes? You are the joke?”

She sighed and dropped the tablet onto the couch beside her, rubbing her face.

This was ridiculous.

She had infiltrated high-security compounds. Taken down armed opponents twice her size. Literally died to save the universe.

And yet here she was, completely defeated by a list of overly pleasant strangers with good bone structure.

It was weird. That was the problem. It was weird to pick someone like this. To reduce something so important—so permanent—to a checklist.

Eye color. Height. Education.

Like she was assembling a person from spare parts.

She huffed.

“This is worse than online dating.”

And she had never even tried online dating.

The more profiles she read, the worse it got. They were all perfect. Which meant none of them felt right.

There was always something missing, something she couldn’t quite define. And Natasha hated not being able to define something. 

But not tonight. Tonight she was going to the movies with Steve.

And she was absolutely, definitely going to tell him.

Maybe he’d help. He was good at people. Better than she was, anyway. He might have some insight.

“Look for someone with strong moral character.”
“Shared values are important.”

He’d probably turn it into a lecture. She almost smiled.

Maybe—

Natasha snorted softly to herself. No. Absolutely not. There was no universe in which Steve Rogers casually offered to be her sperm donor.

That was— Ridiculous. Completely ridiculous.

She didn’t hear a single word of the movie.

Not one.

Explosions could have been happening. Emotional confessions. Plot twists. The end of the world—again.

Nothing.

All Natasha could think about was the conversation waiting for her. How to say it.

Hey, Steve, I’m planning a baby, no big deal.

Hey, Steve, can you help me pick genetic material from a catalog?

Hey, Steve—

Nope. Terrible. All of it.

When the lights came back on, she blinked like she’d just resurfaced from underwater. Steve was already looking at her. Concerned.

Of course he was.

“Are you okay?” he asked gently. “You’ve been… somewhere else all night.”

“Yeah,” she said quickly. Too quickly. “I’m fine.”

Pause.

“There’s something I want to tell you.”

“Okay,” he said, immediately attentive. Of course he was.

A couple bumped into him on their way out, apologizing in a rush. Natasha watched them go, then glanced around at the crowd.

Yeah. No. Not here. Not while surrounded by popcorn and strangers and someone loudly arguing about the ending.

“Do you want to come over?” she asked. “For tea. I’ve got cookies from Laura.”

Steve smiled, soft and easy. “Sounds good.”

The walk was short. Steve talked about his art project, hands moving as he explained something about light and shadow and composition. Natasha listened, genuinely—she always liked hearing him like this.

Passionate. Alive in a way that had nothing to do with war.

It made something in her chest feel… lighter.

At her apartment, he automatically helped with the tea, because of course he did, and then they were sitting on the couch. Close. Too close.

Steve turned slightly toward her, mug in hand.

“Alright,” he said. “What’s going on?”

Natasha took a breath. No overthinking. No strategy.

Just—

“I’m having a baby.”

…Well. That was one way to do it.

Steve froze. Actually froze.

His tea paused halfway to his mouth, his expression doing something complicated and very un-Steve-like. For a split second—just a second—his face fell.

“Oh,” he said. “Oh—wow. I didn’t know you were seeing someone.”

He smiled. It was… not a great smile.

Natasha blinked, “What?”

“Congratulations,” he added quickly. “Who is—when—?”

“Huh? No, I’m not—” She frowned. “I’m not pregnant.”

Now it was Steve’s turn. “What?”

Okay. This had officially gone off the rails.

“I’m going to be pregnant,” Natasha clarified, gesturing vaguely like that helped. “I’m doing it on my own. I just need a donor.”

Steve stared at her. Processing. Re-processing.
Possibly rebooting.

“Oh,” he said again, but this time it landed differently.

Something in his shoulders loosened. Which was… interesting.

“And you’re… looking for someone?” he asked carefully.

She sighed, leaning back against the couch.

“I thought it would be easy,” she admitted. “You pick a profile, done. But they’re all… I don’t know. Too perfect. It feels wrong.” She gestured helplessly.
“I know I’ll never meet him, but this is still—this is my kid. I don’t want to get it wrong.”

Her voice tightened slightly before she could stop it.

“I finally get this chance, and now I’m stuck because I can’t pick a stranger to provide sperm” She made a face. “God, I hate this. I hate even talking about it.”

Steve was very still. Watching her. Thinking. Dangerous combination.

“I don’t have a partner,” she went on, words starting to tumble now. “And I’m not exactly drowning in options. And all these profiles—none of them feel right. And what if I never find one that does? What if this just—doesn’t happen?”

She exhaled sharply.

“Which is ridiculous, because the only thing I’m missing is—” She stopped herself, grimacing. “I’m not saying it again.”

Silence.

“Nat.”

She looked at him.

His expression had changed. Settled into something firm. Certain. Oh no. She knew that look. 

“I’ll do it.”

Natasha blinked. Once. Twice.

“…I’m sorry, what?”

“I’ll do it,” Steve repeated, like he was volunteering for a mission briefing. “If you want. I’ll be the donor.”
