Sure enough, Tony had already made sure to tell the rest of team about what he'd found in the quinjet so there was nothing left for Steve and Natasha to do other than to own up to the fact that they'd been dating for the last few weeks. It was to Steve's surprise and Natasha's displeasure that the team already knew and that they weren't as sneaky as they thought. Bedsides Tony's griping about what they were doing on the jet (making Steve and Natasha's faces turn interesting shades of red) they received nothing but well wishes from the team. Pepper was even able to convince Tony not to have the jet destroyed by going as far as to remind him of their own interesting choices of locale. Tony quickly changed his mind and settled with having the jet thoroughly disinfected.

After the team was made aware of their relationship Steve and Natasha made the decision for Steve to go ahead and move onto Natasha's floor of the tower. Steve had wondered, for maybe a whole of a minute, if the relationship was going too fast but he had pretty much been living with her anyway, just without the other Avengers knowing. Now they knew and he had just gone forward and moved the rest of his things, which was surprisingly not very much. He didn't need to move the furniture, it would stay on that floor awaiting any new member to make use of it and Tony had paid for it anyway. All he'd needed to move was his personal affects and most of his clothes had already made it to Natasha's room beforehand.

Some of the team had asked why they went to Natasha's floor instead of his and the answer was simply because her room had the best view. Her room looked out over the better parts of New York and had the benefit of a beautiful sunrise and his previous room had been situated on the opposite side. Steve didn't mind the move at all. He actually loved it. There was nothing better than waking up in the morning with her in his arms and the sunshine spreading warmth over them both. But the best part was when the sunlight came in just right it lit her hair up in the most blazing shade of red tinged with gold. Steve was sure he'd never get tired of seeing or running his fingers through it.

It was another beautiful morning and Natasha had been awake for several minutes but lay there anyway, enjoying the feel of Steve's fingers in her hair. It really was her most favorite part of the day, where they could lay in silence and just be happy to be with each other. In their line of work it was always best to make the most of their down time and try to enjoy the quiet.

"I know you're awake." Steve said as he enveloped her in his arms pulling her more firmly into his chest so she could feel his hardness pressing into her lower back.

Natasha let out a happy hum and turned around in his arms to face him. "I was enjoying it too much to move." She said and leaned in to kiss him.

Steve didn't waste any time in deepening the kiss and reached down to pull her leg up over his waist. Securing her leg there he tickled his fingers down her leg and made his way to her center. Pushing her folds apart he slid his finger up and down her slit before pushing one, then two fingers, inside to stroke in and out.

Natasha feeling her whole body thrumming with pleasure reached between them for his hardness that she squeezed gently and rubbed up and down. When she started to tease her thumb over the tip Steve removed his fingers from her, pulled her up slightly so she aligned with him better and pushed his length into her with one fluid stroke.

The position they were in, lying on their sides with their bellies and chests pressed flush together, made Steve's thrusts shallow and quick and Natasha's leg thrown up over him had narrowed her sheath. They were clutching and panting against the other in moments. All of it made better by feeling each other's bellies quivering alongside their own in approaching orgasms.

Natasha's head was tossed back and Steve took the opportunity to seal his lips along her neck, sucking her delicate skin into his mouth in what would definitely leave a mark. When he could feel her sheath start to quicken around him he gave a few quick hard thrusts before joining her in his own climax.

Steve pulled himself from inside her but continued to hold her tightly against him as they regained their breaths. Natasha was numbly aware of the wetness from their coupling leaking from her onto her thighs and running onto the sheets. Her last thought before being pulled into sleep was the sheets needed changing anyway.


When they finally pulled themselves from bed they lingered in the shower for just a bit too long and didn't actually make it downstairs to the common area of the tower until just after ten in the morning. It was quite a while later than their usual time. They had themselves a late breakfast before heading to the lab to see if Tony had anything for them to do for the day since there was no eminent end-of-the-world crisis taking place.

When they got to the lab Tony and Clint were leaning over what looked to be blue prints before they looked up to notice Steve and Natasha.

"Just the spy I wanted to see!" Tony exclaimed while gesturing for Natasha to come over.

Natasha walked over to the table that did indeed have blue prints laid out across it while giving Tony a shrewd look, "What do you want, Tony?"

"News through the grape vine has it that my good old pal Justin Hammer has supposedly, finally built a suit that can rival mine. I've already tried hacking into his systems from here but if he has managed to build the suit then he's not keeping information for it on a public server which means I need to get into his building for access. I was hoping my favorite spy and archer would help me out." Tony said in a rush and really laying it on thick.

Natasha was already eying the blue prints of Justin Hammer's building and was feeling a tingle of excitement of finally getting to use her spy skills. She hadn't truly used them in a while and was feeling rusty. The layout of the building was simple enough. She had a feeling this would be all too easy. Not really a challenge but it'd be good enough.

"It looks like you two have already started putting a plan in place. Tell me what you had in mind."

"Pretty simple. The three of us go in tonight after all associates have left. Natasha, you enter disguised as Hammer's secretary under the ruse of having forgotten to finish paperwork. I've met his secretary before and she's pretty flighty. It shouldn't be a problem. Once you're in Natasha, you'll plug this flash drive into her computer. No need to do anything else. Once the drive is plugged in it'll copy everything in his network, public and private. Clint will be watching from this rooftop to make sure there are no issues. Once you've finished, I'll fly in to pick you up with the jet at this location." Tony said pointing out key areas on the digital map he'd brought up.

Steve had stood back and listened but now he narrowed his eyes at Tony, "You'll be getting a lot more information than just whether or not he's replicating your suit Tony. Are you sure that's all you're looking for?"

"I'll admit that, no, it's not. Hammer is dangerous in the technology he builds and he sells it to the highest bidder, no questions asked. The main reason I want in is to see about this suit but while I'm at it I may as well take a more thorough look at what else he's building and who he's selling it to. Any other information Hammer has is useless. My tech is and always will be better. If Hammer is getting too close to something that could turn into a problem it'll be dealt with but for now this is obtaining information only. More than likely he's not even close." Tony said reassuring the others that this wasn't just one of his whims.

Natasha shrugged her shoulders, "I'm in. I'd appreciate something a little more challenging next time though."

"I'll keep that in mind." Tony said then looked at Clint.

"I'll probably be bored but yea sure, nothing better to do."

"Steve, I'll just need you to hold down the fort while we're gone. Banner and Thor should be around if you need any back-up."

Steve gave Tony a droll look, "I'm sure we'll be able to handle it."

"Right then! Clint, Natasha, let's get prepped!"

Steve leaned down to peck Natasha on the lips before heading to the gym, leaving them to get ready. Jarvis would let him know of any issues that required the Avengers and he'd touch base with them again before they headed out.


Later that evening Clint, Natasha and Tony flew out to Hammer's building that was located just outside of Death Valley, CA. The jet had invisibility cloaks and allowed them to go in undetected. Clint was the first to be dropped off at his perch on top of the roof across from Hammer's secretary's office. He'd have the perfect vantage to keep an eye on Natasha should things go south. Tony took the jet around the side of the building near the edge of the parking lot while Natasha checked that her disguise was still in place. She'd had to tie her hair up under a medium length black wig and wore a device in her ear that projected the secretary's face over her own and also changed her voice. She was wearing a crisp white blouse with black pencil skirt and carried a chic black hand bag.

Tony gave her a quick once over and deeming her passable he handed her a badge that would get her into the building and the flash drive that would copy Hammer's network. "Remember, you only need to plug it in. It should take about ten minutes. Then you get back here, we get Clint and we're gone."

"I know how it works, Tony. This isn't my first rodeo." She responded derisively before walking off the jet.

Natasha made it up to the front doors and scanned the badge and with a beep the doors slid open. She immediately was faced with the security officer at the front desk looking like he'd rather be anywhere but there. He simply waved at her as she made her way to the elevator that would take her up to the secretary's office. The blue prints from earlier were spot on and she had no issue finding the secretary's office. Natasha glanced out the window, looking for Clint but knowing she wouldn't see him, she knew he was there anyway. Walking around the desk she pulled out the flash drive and plugged it in to the computer. A little green light flickered on the flash drive and now all she had to do was wait. She was never really good at just waiting though so she started to open up drawers and rifle through some papers, looking for anything that indicated Tony was right.

Natasha was currently leaning over an open desk drawer when she was overcome by a sudden rush of heat and she barely managed to pull the trash can from below the desk before she was vomiting. Instantly she heard Clint in her earpiece, "Natasha, you okay?"

She was still leaning over the trash can, taking deep steady breaths. "Yea, I think I'm okay. Just got nauseated all of a sudden."

She looked at the trash can and grimaced. Definitely a little complication but she thought there was a bathroom just down the hall. She looked at the flash drive and as it was still running she picked up the trash and went looking for the bathroom. She couldn't leave it. That'd be leaving an unquestionable sign that someone had been there. She found the bathroom, cleaned out the trash and when she made it back to the office the flash drive had finished.

Natasha pulled out the flash drive and stuck it in her purse. She made her way through the building again and waved at the guard as she left, making her way back to the jet. Upon entering the jet she showed Tony the flash drive saying, "No problem."

They'd picked up Clint and they were on their way before Clint finally demanded, "What the hell was that?"

That, of course, got Tony's attention. "What the hell was what? What happened? You said there were no problems."

"There WERE no problems."

"Natasha threw up in the secretary's trash can." Clint provided, then, "I don't think I've seen you get sick before."

By that time, Natasha was sending Clint a pretty deadly glare. "It was no big deal. I threw up and I took care of it. I do get sick, just very rarely. The Red Room serum protects me from illnesses. You know that."

"Yes, I do know that. This is why I'm questioning you throwing up in the first place."

Natasha just shrugged, "Maybe it was something I ate. Maybe that pizza from last night."

"The pizza might have been iffy but it's never made you sick before and if it was the pizza then you'd been sick sooner." Clint pointed out.

"I'm fine now. Let's just drop it, okay?"

Clint let it go for the moment but Tony's mind was wondering. What if there had been something in Hammer's building that made Natasha sick? Like it or not Natasha would be checked over once back at the tower.


The ride back went smoothly enough and while Tony flew the jet Clint and Natasha had been dozing but when Tony went to take the jet in for landing a sharp updraft caused the jet to lurch and subsequently Natasha's stomach as well. She searched frantically for something to be sick in before settling on the purse she used for her disguise, upending it quickly and spilling the flash drive and other knickknacks onto the floor, she retched into the bag.

Tony continued to land the jet in the underground hanger, now more determined than ever that Natasha really was sick and had picked something up from Hammer's building. Clint feeling useless and a little grossed out settled for reaching over to rub a comforting hand over her back.

After putting down the jet Tony threw off his harness and started back to Natasha. He leaned over and picked up the flash drive, leaving the rest of the purse's contents on the floor. "C'mon, we're gonna check you over in medical."

Natasha huffed. She was feeling much better now and really just wanted to lie down and sleep, suddenly feeling exhausted. "Tony, I'm fine. Really. I appreciate your concern but I'm sure I'll be good as new in the morning."

"Listen, Natasha, you could've been exposed to something in that building. With the kind of things Hammer has been known to mess with, it really wouldn't be surprising."

"If that was true then wouldn't the other workers be sick too?" She said.

"Not if it was something they were inoculated against and this was meant to make anyone not supposed to be there sick. It could be a security measure of his." He pointed out. Tony thought it unlikely though. Hammer wasn't that smart. But Clint was right in saying that Natasha should never get sick. Something was definitely up.

"Just get checked out, Nat. It'll only take a few minutes and then you can go to bed." Clint pushed.

Natasha gave in and let them lead her into the building, throwing her purse in the trash along the way. She'd really liked that purse, too. Oh well, at least it hadn't been the real designer brand. She'd picked it up for $10 from some seller along one of the streets of New York. The guy probably had loads more. She'd learned a lesson though and would be putting sick bags on the jet from now on.

Walking through the building Natasha asked, "Where are the others?"

"Oh I forgot to tell you guys. They got pulled out about an hour ago to deal with some dumb guy trying to rob a bank downtown. They should be back anytime now." Tony said.

In the medical lab that was used solely for illnesses and injuries, Natasha hopped up onto an examination table while Tony pulled out a syringe and needle. He was just sticking the needle in her arm when Steve still wearing his suit and covered in dirt walked into the room.

Steve took in Tony withdrawing blood from Natasha's arm and frowned. "Jarvis said you were in here. What's going on? Were there problems?"

"There were no problems", "Nat's sick." Natasha and Clint spoke at once.

"Natasha's sick? How? You were fine before you left." Steve said, filling with concern.

Natasha and Clint glared at each other while Tony spoke up and went about putting Natasha's blood through screening, "Natasha MAY be sick. She threw up twice, once in the secretary's office and once on the jet when we were landing. I'm running her blood now to check she didn't pick something up from Hammer's building."

Natasha walked over to Steve and hugged him, "I'm sure it's nothing, just an upset stomach. I blame Clint's pizza from last night."

"It was not the pizza." Clint protested.

Natasha ignored Clint and looked at Steve's suit, "Why are you so dirty? I thought it was only a bank robbery."

Steve laughed, "It was only a bank robbery. Hulk knocked down one of the walls. I was in the way."

"I'm not gonna have to pay for that, am I?" Tony asked.

"No, probably not. The guy was an idiot, only had one gun but he did manage to have two hostages. Hulk took down the wall; it fell on the robber and me. We need to work on our communication skills."

Clint snorted, "Good luck with that."

Tony's machine that was screening Natasha's blood gave a series of beeps and Tony leaned over the computer reading the results. "Well, it looks like you aren't sick Natasha. Must've been Clint's pizza."

Before Clint could protest again, Jarvis interrupted, "Sir, if I may direct your attention to the next part of the readings. I believe I have a plausible explanation for Miss Romanoff's sickness."

Tony looked over the readings. "It says her hCG is higher than average. I'm not a doctor, Jarvis, what is that?"

"Sir, hCG is Human Chorionic Gonadotropin, commonly known as the Pregnancy Hormone. The high level of hCG in Miss Romanoff's blood indicates that she is pregnant. She could be experiencing the so-called 'morning sickness'."

Dead silence filled the room and then Natasha made a dash for the nearest trash can and was sick again.
