Hogwarts AU with stucky?

whtaft:

“Where are you headed?” Natasha asks from her usual spot in the Slytherin common room. She’s not even looking up from the copy of Witch Weekly she’s reading as Steve passes, and Steve will never stop being impressed with her for that skill. No wonder Professor Trelawney likes her so much.

“To the library,” Steve lies.

Natasha looks up for the first time. “You’re a terrible liar,” she says. “Go have fun mooning over the Hufflepuff keeper.”

“I’m not!” Steve huffs. “I just like to study on the Quidditch Pitch. It’s comfortable there.”

“Oh yes, very comfortable with the wind blowing and the players shouting and Bucky Barnes looking oh so handsome in his training robes.”

“I don’t even know who Bucky Barnes is,” Steve says. “Who’s that? I don’t even—”

“He’s been your potions partner for two years,” Natasha says. “You literally rode in the same train car on the way to school this year. He stopped by the table yesterday to—”

“I am going to the Quidditch Pitch because I need to ask Bucky a question about the Potions homework after he’s done with practice,” Steve says in a way he knows is convincing.

Natasha looks back to her magazine. “Sure,” she says. Feeling satisfied, he turns around just to have her say, “Rumor is that Bucky got a new uniform that he’ll be showing off today…”

Face red, Steve storms out of the common room, hearing Natasha call, “Make sure to report back on all of their moves!” as he goes.

When practice ends, Bucky flies into the stands, new robes billowing out behind him, then hops off of his broom and into the stands next to Steve. “Hey,” he says.

“I’m not spying,” Steve says.

Bucky raises an eyebrow as he removes the goggles he likes to play in. “Okay,” he says, setting the goggles down next to his broom.

“I’m serious,” Steve says. “I’m not.”

“That’s just making me think you are, you know,” Bucky teases, plopping down next to Steve. “But you want to know how I know you’re not spying for Slytherin?” he asks.

“How?” Steve asks, knowing he’s a fish going to the bait.

“You don’t know what any of the plays are,” he says, grinning.

Rolling his eyes, Steve says, “And I’m also not here just to moon over you,” he says.

“Oh?” Bucky asks. “I mean, you are a pale blob hanging up in the skies and watching me.”

“It’s not mooning when the affection is mutual,” Steve says with a frown.

Bucky grins, then leans in for a kiss. He smells like sweat, his hair’s a mess, and his lips are chapped, but Steve still grins into their kiss just like it’s the first time.

“I think you were sunning,” Bucky says as he pulls away.

“Sunning?” Steve asks.

“The opposite of mooning. You still stare at someone from afar but you know that they’re staring at you back.”

“Oh, so that’s why you messed up that one play,” Steve says with a solemn nod.

Bucky pokes his side. “Asshole,” he says.

“Hufflepuff,” Steve shoots back.

Bucky grins and Steve can’t help it. He leans in for another kiss.
