Sam/Clint/Bucky, "why do you care?" (hi!!) (is that winterbirds or is winterbirds something else?)
“How about dinner and a movie after this?”
“It’s a date,” Sam says without looking up from his newspaper. “Barnes? You coming?”
Clint catches the dubious expression on Bucky’s face. “On your date?”
“Sure,” Sam replies. “Why not?”
“You gotta leave the Tower sometime, Buck,” Clint tells him, digs his fingers into Bucky’s side just for the reaction. “C’mon. Sam’ll pay.”
Sam sighs, but he doesn’t argue.
“Why do you care what I do? Anyway, I’m not interested in being your third wheel.”
Sam sends an extremely resigned look at him over Bucky’s head. Clint shrugs back. Bucky’s pretty good at seeing an enemy from a million miles away in combat, but he’s fantastically short-sighted when it comes to people trying to flirt with him. (That worked well for them, because he completely blanked out on that guy from the R&D division in Stark Tower.)
“We’ve been trying to get you to go on a date for the last month,” Sam says. “Does that sound like third wheeling to you, Barnes?”
“I don’t want you to set me up with anyone either,” Bucky says, and Sam throws the newspaper at his face.
Clint’s pretty sure this isn’t going to get anywhere if he doesn’t do something drastic, so he throws a knee over Bucky’s thighs to keep him where he is and then cups his cheek and kisses him with intent.
“You’re coming with us,” Sam says when Clint lets him go, and Bucky’s looking a little dazed from it but he says yes, so Clint feels like he’s earned the victorious high-five Sam reluctantly awards him.
