A/N: I kind of love Natasha. Where would Tony be without her? XD

Disclaimer: So, I don't own anything really. I don't even like coffee. Good thing my muses do.

Tony stirred his cappuccino absently as he studied the data Jarvis had prepared on the new suit. It wasn't as maneuverable as Tony had hoped. He would have to tweak it a little. Or a lot.

But that could wait until later. Right now was break time. It was nice to get out of the workshop in the wee hours of the morning before the rest of the Avengers filled up the kitchen and pestered him to work on gadgets for them. He loved them like a dysfunctional family, but god, he needed space sometimes.

The door creaked open and Tony looked up in annoyance. But he relaxed when he saw it was just Steve. Steve never asked Tony for anything. That alone would have made him Tony's favorite, but he was also hot. And Tony was always happy to be in the company of such spectacular eye candy.

Steve stared at Tony warily. "You're up early," he said.

"Actually, I'm up late." He lifted his mug to take another sip.

Empty. Damn.

Tony got up and stuck his mug back under the cappuccino machine and fiddled with the buttons as he waited for his coffee.

Steve's eyes were following him. Probably silently judging him and his caffeine levels.

Tony returned to his seat, prepared for a lecture about too much caffeine and too little sleep, but it never came. Steve was just staring intently at his mug.

"Vanilla cappuccino," Tony said. "Natasha insisted on getting the machine and I can't really blame her. This stuff tastes amazing, especially the nice layer of foam on the top."

Steve made a strange noise in the back of his throat and looked away. Typical. Steve didn't drink anything besides the old-fashioned thick black sludge. And Tony was really tired of how horrified Steve reacted to flavored coffees.

"Oh, come on, Steve. Just give it a try. You might like it."

"No," Steve said, his voice sounding oddly tight.

Well, okay then.

Tony sipped at his coffee, trying not to feel hurt that Steve refused to even look at him, much less have a conversation. But Steve had been rather unsociable the past few days, acting jumpy and uneasy all the time. Tony had no idea what was wrong. When asked, Steve always insisted he was fine.

"Good morning," Natasha said, padding into room.

Steve tensed.

She grabbed a bagel off the counter and raised an eyebrow. "It's nice to see the two of you enjoying breakfast together."

Steve's jaw tightened. "Leave me alone," he growled.

"Are you two fighting?" Tony asked, looking between them curiously.

"No," Steve said. But the look he shot Natasha was anything but friendly.

"Steve's just being unreasonably stubborn," Natasha said serenely as she spread cream cheese on her bagel. "He'll get over it."

Steve huffed and crossed his arms over his chest, facing away from both of them.

Well, this was weird. Maybe Steve was right about his sleeping habits because Tony was obviously hallucinating. Or maybe he just hadn't had enough coffee yet.

He took another long drag from his coffee cup. Mmm. This stuff was the best. He could already feel his brain waking up.

"Would you stop that?" Steve snapped.

Tony blinked. "I'm not doing anything."

Steve groaned and put his head in his hands.

Whatever. Tony was just going to enjoy his coffee whether Steve liked it or not.

Oh. Nothing but a ring of foam left around the mug. Damn. Tony scraped the spoon around the edges of the cup and licked every last bit of foam off the spoon. No sense in letting it go to waste.

"I can't take this anymore!" Steve exploded. He stormed out of the kitchen.

Tony froze, spoon halfway to his mouth for another lick. "What just happened?"

Natasha shook her head. "You are shameless," she said.

"Me? I didn't even do anything this time."

Natasha snagged the spoon from his hand and popped it in her mouth. She delicately licked the back of the spoon and then dipped her tongue into the smooth curve.

He watched her with fascination. "Nat, that is obscene," he said.

"I know." She arced the spoon towards the sink. "You're a smart man. Just think about it."

Think about what? How she was licking the spoon that he had just been...

Oh.

Ohhh.

This explained everything. Steve wasn't mad at him. It was quite the opposite. Steve was mad at himself for not being able to control his libido.

Tony was going to have to do something about that.
