A/N - this imagine is based off a headcanon that Steve slipped up once, said 4th of July was his birthday, and didn't have the heart to tell the truth after.

You looked down at your phone as it buzzed, and saw a text message from Stark 🙄.

Stark 🙄: Hey Y/N it's fourth of July. You know
what that means!

Y/N: you know it's not actually steve's
birthday today right?

Stark 🙄: Yep! But he gets all squirmy and
nervous. It's hilarious!

Y/N: but do i want to prank my boyfriend?
assuming that's what you have in mind

Stark 🙄: *motions hands excitedly*

Y/N: yes. yes i do.

Stark 🙄: Thanks Y/N! You're an angel!

Y/N: i do try don't i

Stark 🙄: I know exactly what to do. It involves
you, Bucky, and some very patriotic outfits ...

"All right, Tony, what's up?" a very confused Steve asked from behind his blindfold.

"You'll see," Tony smirked. He whipped off the blindfold to reveal a chair, which he shoved Steve into, in front of a stage.

"Happy Birthday, babe!" your voice said behind the red curtains. Steve's face immediately turned the same shade, and he was seized by an unfortunate grip of guilt. "I wanted to give you a special birthday gift, which Tony helped with."

"I never agreed to this," Bucky's muffled voice complained.

"Too bad, Barnes!" you sang.

Music started playing ... and it was then that Steven Grant Rogers knew he was doomed. The curtains slid open to reveal you and Bucky in skimpy American flag dresses.

"Who's strong and brave here to save the American Way?"

"Tony, you shit." Steve moaned as you and Bucky started dancing, high kicks and all. He practically buried his entire face in one of his hands.

"Who vows to fight like a man for what's right night and day?"

"That's what you get for lying to the public about your birthday." Tony smirked.

"Who will campaign door-to-door for America?"

"You know it wasn't intentional."

"Carry the flag shore to shore for America? From Hoboken to Spokane. The Star Spangled Man with a Plan!" You and Bucky waved your flags enthusiastically.

"Y/N/N, you, uh, you know it's not really my birthday today right?" Steve asked uncomfortably as you jumped off the stage.

"Yep," you smiled, and he melted. "But Buck, Tony and I thought it'd be funny."

"Well, it kinda was," the super soldier admitted. You stood on your tip toes and kissed him. Steve may be bashful, but his kisses were anything but. You sank into his arms happily, even having the balls to whisper 'Happy Birthday' against his lips and hear him give a long-suffering sigh as you pulled apart.

"Would this be a bad moment to admit I filmed the whole thing?"

"TONY!" you yelled, though you were grinning.

"Fuck, I'm dead-"

"Come back here!"
