The Avengers are put in quarantine after being exposed to a chemical that could spread an illness and they mess with Steve and Natasha about their feelings for one another. 

"What do you mean we have to be locked in here for two weeks?" Natasha argued, looking at the hologram of Nick Fury with a glare that could kill. 

Nick sighed, "You've all been exposed to a chemically engineered illness that won't kill you six, but could cause a lot of problems if it spreads." 

Steve sighed, "So we can't leave this place for two weeks? What about food and supplies?" 

"I'm sending two weeks worth of supplies now. They'll drop it off on the porch. If you need anything else just call and I'll have someone bring it by." 

"This house is like four bedrooms Fury," Clint said, frowning at the idea with sharing a room with anyone.

"I call dibs on my own room," Tony called out. 

"I'll take the couch," Bruce offered. 

"I'm not sharing a room with anyone," Clint said. 

Fury sighed, "You're all grownups. Figure it out." 

With that, he hung up. 

Steve shifted nervously. He didn't exactly want to share a bed with Thor but he also knew that Natasha shouldn't have to share a room. 

Before he could say anything about the situation Natasha sighed, "Steve and I can bunk up." 

The others looked at the her suspiciously but she was already  heading up the safe house's rooms. 

Steve followed behind her, ignoring the curious looks his teammates gave them and walked into the room she had gone into.

"You sure you don't mind sharing a room?" Steve asked hesitantly, "I can just set up a cot on the living room floor or something if you want the privacy." 

Natasha rolled her eyes, "It's fine Steve. I don't mind. If I had, I wouldn't have suggested it."

"Alright," Steve said with a small nod before noticing a large cut on Natasha's arm, "You okay?" 

Natasha glanced down to her arm, "Yeah. It's probably not even deep enough to need stitches." 

Steve wasn't sure he believed that. If the amount of blood coming from the cut was any indicator, the cut was much deeper then she was letting on, "You sure? I can help you stitch it up if you want." 

Natasha looked like she was about to reject his offer but eventually nodded, sitting down on the bed and ripping the already torn sleeve of her suit off. Steve frowned when he saw the cut. It was deep and long, spanning from her shoulder down to just above her elbow. 

"What happened?" He asked, grabbing the first aid kit from the closet. 

Natasha shrugged, "I was fighting off a few guys and one of them managed to pull a knife on me. Thought he was winning at first when he saw that he cut me, but then I put his own knife in his thigh and he left me alone." 

Steve couldn't help but chuckle a little bit. Natasha was nothing if not capable of handling herself in a battle.

He started stitching up the cut and noticed how Natasha's gaze burned into his forehead as he worked. It was distracting and almost made him poke himself with the needle on several occasions. 

"There, good as new." Steve said when he finally finished. 

Natasha looked down at her arm and admired the clean even stitches, "Thanks Rogers." 

Steve nodded, looking up at Natasha and becoming instantly aware of how close he was sitting to her. 

"Anytime," He whispered, losing his train of thought as she stared back at him, searching her eyes with her own. Perhaps for a sign that he felt as she did. 

Had a loud crash not interrupted their moment, she probably would have found out. 

"Jesus Christ. We've been here an hour and they've already broken something," Natasha mumbled, rolling her eyes at the thought. 

Steve stood up, cursing himself for not making a move. That had been his chance. 

He sighed, "I guess I should go check that out."

Natasha nodded, "I'm going to jump in the shower, make sure none of them kill each other." 

Steve nodded with a small smile and left the room. 

When he got down to the main level, the others were all standing there with a pile of broken glass in front of them. 

"Damn it," Clint muttered, walking away while Tony shook his head. 

"Seriously Cap!?" Tony asked, handing Bruce and Thor each twenty dollars while Clint did the same. 

Steve frowned, "What?" 

Tony shook his head, "You and Widow seriously aren't going to address the elephant in the room?" 

Steve furrowed his eyebrows, "What elephant?"

Clint scoffed and Tony sighed, "Natasha gave up her own bedroom and willingly bunked with you and you're trying to tell us that there's nothing going on between you? Because Clint and I bet Banner and Point Break 20 dollars that you were up there doing the do and would ignore the crash, but since you did, I think we deserve the truth. And 40 dollars." 

"There's nothing to tell guys. Nat and I are friends," Steve argued, trying to fight his rising blush. 

Clint shrugged, "Yeah right. And me and Tony are getting married." 

Steve frowned, "I'm serious. There's nothing going on. I was helping her stitch up a cut she got during the fight."

"Why are you two so against them just being friends?" Bruce asked. 

Tony stood up, "Because they are always together. No one spends that much time with someone they aren't fucking." 

Steve choked on the air around him and started to cough, "What?"

Thor nodded, "I agree with Stark. You two make a lovely couple though." 

"Who makes a good couple? Did Steve finally get a girlfriend?" Natasha asked, coming down the steps. 

Tony grinned, "You would know." 

Natasha turned to Steve and raised her eyebrow, "Did you finally ask Sharon out or something?" 

Steve blushed again, "No-they um- well they think we're dating." 

"Not just dating," Tony pointed out, "I think Natasha here has taken our innocent Captain's virginity." 

Natasha raised her eyebrows before grinning slowly, "You guys really think that if the two of us were doing something, you wouldn't hear it?" 

Tony and Clint both groaned, Thor looked mildly amused, and Bruce, well Bruce was just uncomfortable. 

Steve couldn't do anything but stand there as red as a tomato. 

"I hate you sometimes," Clint mumbled, shaking his head as if he were trying to forget the last two minutes of their conversation, "For the record, I just thought you guys were dating."

Natasha shrugged, "Nope. Not yet."

With that, she grabbed an apple from the kitchen and walked back upstairs without even glancing over at Steve, who couldn't seem to process everything that was happening. 

"Did she say not yet?" Steve asked weakly a few moments after recovering from his shock. 

Clint nodded, "Yeah, and Natasha's not a very patient woman so if I were you, I'd go after her."

Steve nodded and quickly jogged up the stairs behind her. 

"Double or nothing that if we do the same thing in thirty minutes, they don't come down," Tony said, turning to his teammates, who simply shook their heads. 

Steve knocked on the bedroom door the second he was up the stairs. 

His jaw dropped slightly when Natasha opened the door in nothing but a white cotton robe that was loosely tied around her waist. 

"Hi," He managed, sounding like a pubescent teenager who didn't know how to talk to his crush. 

Natasha smirked, "I was wondering how long it would take you to come up here." 

Steve stepped inside the room and racked his brain for something to say...anything to say. By now, he had been standing in front of her silently for far too long. 

"You wanna know why I said not yet?" Natasha asked, turning away from Steve and walking towards the bed, sitting down and motioning for Steve to do the same. 

He nodded, "Were you just messing with the team or did you mean it?" 

Natasha shrugged, "That's up to you." 

Steve frowned, "What do you mean?" 

"I mean that if you don't want anything to happen, it won't, but if you do, then it will."

Steve looked down at Natasha. Her words were confident, as though she didn't care either way, but looking into his eyes he could suddenly see how vulnerable she was in this moment. She had just offered him a relationship...and as far as he knew, she hadn't ever offered someone that before. 

He'd be a damn fool to reject that. 

"I do." 

Natasha looked surprised for a moment but quickly replaced her surprise with another flirty smirk, "You do what?" 

"Want something to happen." 

Natasha smiled, wrapping her hands around his neck cautiously, "Then make something happen Rogers. I'm all yours." 

Steve relaxed into her touch and slowly leaned forward to kiss her, letting himself get lost in everything about her. Her touch, her scent, the way her lips tasted. He had longed for this moment for so long, and now that it was finally here, he wanted it to last forever. 

"You're a damn good kisser Steve," Natasha breathed out when they pulled apart for a moment. 

Steve was breathless, that was easily the best kiss he had ever experienced. He wanted to tell her as much but he had a hunch that every kiss they shared would only get better and he didn't want to seem repetitive. 

"Well I'm not as innocent as Stark thinks," Steve settled for, trying to flirt a little.

She laughed a little and reached up to place a few kisses along Steve's jaw, "Don't worry, he won't think you're that innocent after tonight." 

Steve turned his head and caught Natasha's lips with his own, falling onto the bed with Natasha beneath him as their hands explored every inch of the other's skin. 

There was a crash from the living room again, causing the two to separate for a moment.

"Leave it," Natasha said, pulling Steve back down for another kiss. 

That night, she made do on her promise to Tony. They did all hear it when something was going on between her and Steve. 

Hey guys. So I originally was going to draw this out much longer but I have my first day at my new job tomorrow and need some sleep so I shortened it just a little bit. There wasn't a lot of quarantine going on but I just like to imagine the others now having to live in close quarters with newly dating Romanogers.
