An Iron Resolve (Marvel)(Time Travel)

A/N: Natasha finally makes her move. Or more accurately, 'Natalie Rushman' makes her move.

-x-X-x-

Natasha was done playing games. More specifically, ‘Natalie Rushman’ was done playing games. She’d been undercover working as the shared personal assistant of Tony Stark and Pepper Potts for months now, and she felt like she barely had anything to show for it save for two major things.

First, while it had taken her an embarrassing long time to finally figure out who ‘J’ was, Natasha had eventually cracked it. By just asking point blank after hearing the Posh British voice coming from the ceiling for several weeks straight. As it turned out, J stood for JARVIS… and JARVIS stood for Just A Rather Very Intelligent System.

Stark described JARVIS as a natural-language user interface. After coming to understand the thing a little better, it became far more obvious why Stark didn’t think he needed her. JARVIS didn’t have hands, but in a world as digital as the modern era was, that didn’t really matter. All Stark had to do was give his digital butler orders and JARVIS would not only pass them on with lightning speed, but he could even go farther by taking the initiative and seeking out the proper people who would get whatever Stark wanted done as fast as possible.

What Natasha understood from all of this, and what Natalie Rushman didn’t quite ‘get’… was that JARVIS was more than just a user interface. He was a full-fledged Artificial Intelligence. Stark seemed to keep him on a short leash of course, but this explained why SHIELD had such issues with breaking into Stark Industries’ servers after Stark came back from Afghanistan. That must have been when he turned JARVIS from a normal user interface into a full-fledged AI and tasked him with defending his company from all would-be intruders.

Luckily, JARVIS clearly wasn’t perfect or she wouldn’t have been able to slip in under the AI’s radar like she had. It was also lucky that Coulson and Fury had decided to have her take the slow approach with this infiltration, because otherwise she would have almost certainly exposed herself unknowingly to the AI in the several weeks it had taken her to figure out exactly what he was.

With an understanding of JARVIS’ true nature came the understanding that Natasha really couldn’t act the way she normally would. Snooping around Pepper Potts’ Office or Tony Stark’s Laboratory would inevitably be picked up by the ever-present digital interference in the building, and she would quickly be caught out.

Instead, Natasha had spent the last few months working on something else… trying and failing to seduce Tony Stark and Pepper Potts individually.

She’d actually clocked rather early on that she wasn’t getting anywhere with both of them. Natasha had also realized that this was at least in part because they were tied at the hip. However, she’d been able to confirm that the two were in an unconventional relationship with both Maya Hansen and Helen Cho, just as the rumors had said.

It wasn’t that Tony and Pepper weren’t willing to fuck other women… rather, it was that they weren’t willing to fuck other women without one another present.

Natasha Romanoff had figured this out within a couple of weeks of working under them. But she’d ultimately decided that Natalie Rushman needed to spend a few months learning the same thing. Only now, after several months of increasingly ‘desperate’ attempts at getting into their respective beds, was Natalie finally going to pull a Hail Mary.

As the door to the bedroom opens, Natasha makes sure everything is perfect. She has a hopeful, vulnerable, and expectant look on her face. One leg over the other as she sits on the edge of the bed. And oh yeah, she’s wearing a lacy white corset and a pair of matching white panties and nothing else, her red curls cascading over her bare shoulders as she bites her lower lip and straightens up.

Both Stark and Potts quickly clock her presence, even though they’d been kissing one another just a moment earlier. Pulling apart in the open doorway, they look at her in surprise but also curious arousal. The CEO of Stark Industries is the first to speak, her lips curling into a wolfish smile as she slides her gaze up and down Natasha’s body.

“Ms. Rushman. What a surprise.”

From beside her, Stark is doing the same for a moment, making no secret of the fact that he’s checking Natasha out. But then his gaze darts to the ceiling.

“A surprise indeed. JARVIS, you didn’t tell us that there was an intruder.”

A moment later and the British Voice of Stark’s AI, familiar at this point, fills the room.

“I did not think Ms. Rushman counted as an intruder, sir. Besides, you and Ms. Potts have been spending increasing amounts of time recently discussing Natalie Rushman’s body and how it fits into her work clothing. It seemed that you would enjoy the opportunity to see her in her latest choice of attire.”

‘Natalie Rushman’ blushes furiously at the voice from on high’s dry wit. Inwardly though, Natasha is crowing in victory. Which for her means she’s internally smirking to herself. Just as she’d thought, if this wasn’t the right play then JARVIS would never have let her make it this far in the first place.

Pretending to fiddle with the lace of her lingerie, Natasha bites her lower lip as she looks at Tony and Pepper, doing her very best to project vulnerability, anticipation, and trepidation all at the same time. Judging by how they manage to look even hungrier as a result, she’s succeeding.

“I… I can go if you want sir, ma’am. I just… you both have… w-well, I thought if neither of you wanted me on your own… maybe you’d want me… together.”

The very rich couple exchange a pair of looks at that… and then wordlessly move deeper into the bedroom together.

“You thought right, Ms. Rushman. Tony and I share everything with one another.”

“Not long ago I wasn’t really the sharing type. But then something happened that changed my outlook on life. You might have heard of it.”

Natasha ducks her head in faux shame as Tony dryly brings up his experiences if Afghanistan. She’s tempted to slip in a question about his escape, but now isn’t the time. No need to ruin the moment or garner suspicion.

His hand runs along her body… as does Pepper on her other side. They sit on either side of her and Natasha finds herself penned in. Of course, neither of them has any idea just how dangerous she truly is. And she has no intention of letting them find out. Instead, she allows them to touch her, encouraging it with soft mewls and moans as ‘Natalie Rushman’ seemingly succumbs to their combined efforts.

“I learned not to let my own insecurities get in the way of my happiness anymore. First thing I did after getting back was kiss Pepper here right on the lips. The rest is history.”

Looking up at Tony with wide eyes, Natasha bites her lower lip.

“That’s… that’s very romantic, sir.”

Tony grins a confident, cocksure grin at that. The sort of grin that would make a girl like Natalie Rushman melt in the palm of his hand if she were real. When his palm finds her mound and begins to run along it, Natasha makes sure to hump at his hand, moaning and getting nice and wet for him, just like her cover would.

At the same time, Pepper isn’t idle. She’s not just watching as her very rich boyfriend has his way with his Personal Assistant. Leaning into Natasha’s side, Pepper’s breath ghosts across her ear, causing Natasha to moan as she whispers to her.

“Honestly, Tony is too much man for any one woman to handle, Ms. Rushman. Even me. Just remember that he loves me above all else… and you’ll be fine.”

A weakness? An insecurity? Natasha files it away for later consideration, even as she nods her head rapidly at Pepper’s words. Getting in the middle of Stark and Potts’ relationship wouldn’t be easy if the last few months were any indication. However, now that she was getting in the middle of them in another more carnal way, it might be a possibility. Once Tony saw what she was truly capable of, he might just start to find himself falling in love with her instead.

It wouldn’t be the first time that Natasha poisoned a seemingly happy couple from the inside. Men were men and women… women could be so jealous at times.

But that was for later. For now, Natasha focuses on the moment… and making sure that both parties have every reason to be happy with how this night turns out. Her hands finally come up from where she’d had them ‘nervously’ tucked at her sides and Natasha glances from Tony to Pepper and back again as she inches her fingers towards their crotches.

“S-Sir? Ma’am? M-May I?”

She expects approval. She expects permission. For the first time since the encounter began, Natasha is a little caught off guard when the power couple instead snatch her hands up by their wrists and pull them over her head, pushing her onto her back on the bed a little faster than she was anticipating. The surprised blink that she gives them as they pin her down and loom over her isn’t entirely faked, even as she makes sure to blush hard and squirm even harder underneath them.

“Oh, I’m afraid not Ms. Rushman. All of your teasing these past few months has gotten me and Tony quite hot and bothered. So you’re going to lay there like a good girl and allow us to explore your body at our leisure, alright? And then, maybe, if you’re very good… we’ll consider letting you touch us later. Am I understood?”

If nothing else, Natasha has to admit that Pepper makes for a good dominatrix. Whimpering, the undercover agent nods her head emphatically, causing the CEO of Stark Industries to smile and coo down at her before grasping her by her face and kissing her. Meanwhile, down below, Tony goes from merely palming her hot sex to slipping his fingers inside of her, moving his hand past her panties so he can drill her.

Natasha is more than wet enough for him, of course. She’s been trained to act this sort of role perfectly. However, as things progress, as the night goes on… not all of it is as acted as she might have preferred. She was expecting Tony and Pepper to be selfish lovers. She was expecting the couple to take advantage of her and use her for their own pleasure first and foremost.

Instead, what she gets is quite surprising as they coax mewling cries and wanton moans out of her. They focus on her first, doing their best to turn Natasha into a puddle of pleasured flesh, likely for their own amusement. And Natasha lets them of course, playing the role of Natalie Rushman in over her head perfectly. She gives them exactly what they want. But at the same time… she has to admit, they give her more than she expected as well.

They do fuck her properly, eventually. Tony buried deep inside of her, Pepper sitting on her face. And then Natasha on her hands and knees, mouth buried between Pepper’s thighs, Tony’s cock filling her from behind. And then her on top, riding Tony Stark while Pepper instead rode HIS face and fondled Natasha’s tits, kissing her deeply.

The positions that three very beautiful, very aroused people can engage in are endless as the undercover spy already knew. But what she didn’t know was just how long Tony and Pepper could go for. As their ‘shared’ PA, Natasha knows their schedules inside and out. She knows full well that they don’t make time for working out, even if they eat relatively healthily.

Of course, in Stark’s case, he doesn’t eat at all sometimes. Natasha, in her capacity as Natalie, has had to force him to imbibe nutrients more than once.

So then how the fuck are they keeping up with her? No… not keeping up with her. How the fuck are they outpacing her? One time turns into two turns into three and before Natasha knows it, they’ve fucked for hours and hours.

Her instructors in The Red Room liked to boast that they were preparing her to overcome any challenge. They would claim that their training made her and the other girls ready for anything the world had to throw at them. Natasha was a bit more practical than that though. She’d learned a long time ago that nothing could prepare you for every eventuality.

Even still, being… outlasted by Tony Stark and Pepper Potts was a blow to her ego when hours later, she found herself finally reaching the end of her admittedly quite long rope. Her stamina was beyond what most normal humans could ever hope for. And yet… her would-be bosses had still managed to bring her to this exhausted state where she could barely keep her eyes open.

She was sore in a surprisingly pleasurable way, as well as covered in sweat. They’d had a couple of showers together as the night ran long, the three of them, but these most recent rounds had gotten them dirty again. Only Natasha isn’t quite sure she could even manage to climb into a shower if they decided to wash up one final time.

Fortunately, she doesn’t have to find out. Tony and Pepper’s naked bodies press up against her own unadorned flesh on either side and they seem perfectly content to just cuddle at this point, even as Natasha struggles to keep her eyes open.

“It’s alright darling. You did well to last as long as you did. Sleep now.”

“You did good, Natalie. Very good. Pep is right. Rest up.”

That last bit, more than anything, convinces Natasha she’s finally making progress. Tony Stark hasn’t gotten her full name correct on the first try… ever. And yet just now, he called her by her cover’s proper first name. Not Natalia. Not Natie. Not Melanie or Mallory. But Natalie.

The smile that spreads across Natasha’s sleepy face doesn’t even have to be faked in the end. Finally she’s making some progress. Finally, she’s getting somewhere with these people.

Coulson… Coulson is bound to be happy, once she’s finally able to report in on her scheduled vacation in just a few more months. She’ll try to have a lot more for him by that point though. Somehow, she doesn’t think ‘Stark has an AI and him and his girlfriend are insanely skilled lovers’ will be enough all by itself.

But that’s alright. She’s in now. And for the next few months, she’ll use her new position as sexual relief aid to Tony Stark and Pepper Potts to uncover as much information about the two as she possibly can.

A/N: Yes Natasha, you're finally in. Totally. Keep up the good work! :P

Tony and Pepper might be having a little too much fun with their pet spy~
