Author's note: As of the first few chapters, this story is rated PG-13.

It was a special kind of night at Avengers Tower.

Our heroes had just rid the city of another nefarious criminal. Fred Stone (which Tony declared was a "shitty" alias) was the boss of a highly successful and incredibly secretive prostitution business. It had been a long and difficult operation to nab the criminal, but the Avengers knew they especially had to thank Natasha and Clint for their success. The SHIELD agents' stealth training had proved vital to the operation. Banner may have been able to act a different part if he absolutely had to, but Thor and Tony didn't do stealth- it simply wasn't their style.

Because another baddie was off the streets and the heroes had been granted some time off, Tony had decided they needed to party.

Stark had never seen the deadly Black Widow drunk in his life. She completely lacked the ability to relax, but it seemed like the copious amounts of alcohol she'd already ingested were forcing her to sit still and stop her constant vigilant stance.

Tony shifted his eyes from the redhead to the man next to her. Natasha's head was back in uncontrolled laughter, her cheeks flushed and tears streaming down her face. Barton sat with one hand on her knee and the other holding his second beer, his eyes trained absently on her face.

The partners never got wasted at the same time, some kind of agreement they'd worked out long before Tony had met them. They were two of the most mistrustful people he'd ever seen, but sometime during their years of partnership they'd developed a trust more powerful than the arc reactor.

He wondered when they'd finally get their shit together and just get married already.

"Huh?" Steve asked beside him. Realizing he'd spoken aloud, Tony quickly spat out an excuse and tapped Pepper with his foot.

"Did I mention how gorgeous you looked today?" he batted his eyes at her, and she smirked, feeling slightly drunk herself.

"Stark, it's your turn." Natasha ordered, taking a long chug from her cup.

He fought to control his evil smile. She was a treasure trove of secrets that was locked up tighter than Fort Knox, but maybe while she was drunk she wouldn't be quite so protective of the goods.

"Natasha."

"Narcissistic bastard." She acknowledged.

"I-" he frowned at her. "Whatever. Where and when was your first time?"

He hated secrets- not when they were his, but when other people kept them from him. Natasha never told him anything, not even the time of day if he asked. If she was drunk enough to tell him something like this, he'd use it against her as much as possible in the future.

He realized when she opened her mouth that he should clarify a point. "After the Red Room."

Her mood dipped upon mention of the place, as it always did, and the other Avengers held their breath. Was Tony crazy, mentioning that place so carelessly in front of the Russian spy?

Thankfully her drunken state allowed her to forgive and forget rather quickly. She leaned into her partner's side like she needed a little break.

"You don't want to know that." She slurred in Tony's direction. He realized that she was probably the drunkest one in the room right now, even though he was quickly catching up.

"Uh, yeah. I do."

"Why, jealous?" she smirked at him.

He raised an eyebrow. He'd made a big deal over her body when she'd first signed on as his assistant, but he was already hopelessly devoted to Pepper at that point and just trying to keep her in the dark about it. "Not at all." He planted a messy kiss on his girlfriend's cheek, and she let out a drunken giggle. He smiled widely- sober Pepper never giggled.

"Did anyone ever notice that all of the females present have red hair?" Thor randomly interjected. He was surrounded by mugs of some drink he'd brought with him from Asgard. The other Avengers were forbidden to touch the stuff; apparently one sip would have them at death's door.

"I was 18." Natasha said, regaining Tony's attention.

"Huh." He'd been younger then her, then, at his first time.

Noticing his gaze, she waved a dismissive hand. "I was 13 when I lost my virginity. But you said out of the Red Room, so I was 18."

Barton, who'd been in the middle of sipping his beer, spit it out in a rather unceremonious fashion. "You never told me that. 13? Christ."

She shrugged indifferently, her eyes stormy.

"Who was it with?" Tony pried, twirling a strand of Pepper's hair around his finger.

Natasha had gone off to another world, so Tony took off his shoe and threw it in her general direction. It was a move that would have landed Tony in the hospital on any other occasion, but right now she seemed to have missed the assailant's identity. "Huh?"

"Who. Did. You. Sleep. With."

"Oh." Natasha shrugged nonchalantly. "Barton."

The poor archer had just attempted another sip of beer when she spoke, and out came another mouthful all over the floor. "What?"

The room went relatively silent.

"You know you're gonna have to tell the story now, right?"

Please, please, please, tell us the story, Tony silently begged her. He didn't think he'd ever been so curious about anything in his life. He'd always suspected that the partners had slept together once or twice, but he never thought his suspicions would ever be confirmed.

Natasha huffed like this was a huge inconvenience to her. She glanced at her partner, who had removed his hand from her knee and was now looking a little green in the face. "Can I?"

He shrugged wordlessly, and Natasha began speaking, slurring the occasional word as she told her story of many years ago…
