Ah, Patriotism
When Natasha stepped into the elevator, Steve burst out laughing. "Shut up, Rogers," she growled, embarrassed at having been seen in this ridiculous get-up. She was used to going undercover for SHIELD missions, but wearing this damned Betsy Ross outfit was not easy. It was just her luck to be sharing an elevator with her boyfriend, THE Captain America himself, while wearing this terrible costume.
The blonde laughed for a few long, torturous moments longer before clearing his throat and attempting to act natural. Natasha could tell by the shaking of his shoulders that he was holding something back, and it was something very difficult for him to resist.
Sighing loudly, she knew that she might as well let him say what he was thinking so she could stop looking at that dumb grin on his face. "What?" She hissed in annoyance.
Steve held out his hand and cleared his throat. "You look very patriotic, Nat."
Natasha's cheeks burned and she scowled. Of course he would say something like that. He had to. "Can it, Rogers!"
But he couldn't stop just yet. "Looking at you makes me feel like singing the national anthem."
The redhead's hands clenched into fists and she closed her eyes, hoping the doors would open soon. She never should have allowed him to have the go ahead to speak. Now he was on a roll and when Steven Grant Rogers was on a roll, he wouldn't stop until he was finished.
"Stop. Talking."
And, of course, he didn't.
He needed to get one more in before the doors opened, so he pumped his fist in the air and said, "God bless America!" Natasha was ready to yell in frustration at that point when the elevator doors slid open.
Without hesitation, she ran from Steve, cheeks faint pink from embarrassment. Mentally, she began to work through a plan to get sweet revenge on him for his relentless teasing.
Unable to resist just one more joke, Steve poked his head out and called, "Honey, don't forget to finish sewing the flag when you get back home!" It was enjoyable to watch her scamper off in that huge dress. She was even wearing the little white cap on her head too! If he had been thinking at the time, Steve would have taken a picture of her.
The elevator doors closed and even though he knew that Nat would kick his butt later for teasing her, Steve didn't regret it one bit. It wasn't every day he got to make fun of the Black Widow.
