Everyone on the team had been hesitant to let a teenager be apart of the Avengers. Come on, he's what, 18? 19? Surely a person of that age couldn't handle himself against an alien race.

But they let him join anyways because hey, he's wicked smart and can stick to nearly every surface there is. Tony had made him walk all around the Tower, on the walls, ceiling. It got to the point where Tony had to be put into a separate room when he suggested Peter to hang off of Hulks arm.

"Just let me try."

"No."

"C'mon, only for like, two seconds, then I swear I won't bring it up again."

"No."

"...please?"

"No." Steve huffs, rubbing his temple as Peter frowns and swivels in his chair restlessly. And then he whistles, starting Steve and he looks up right as you pass by with a small wave.

"She's hot," Steve's eyes widen, and the pen in his hand snaps and ink splatters all over Peters shirt. "Ah, man! Aunt Mays gonna to kill me,"

Steve doesn't apologize, but quickly does so when you enter the room.

"Jesus, Steve," you gasp, giving your boyfriend a look as you go over to Peter, who's staring at you with a small grin, but you don't seem to notice. "Sorry about that. Steve has zero coordination outside of the battle field. The stories I could tell you about him dropping everything from a coffee cup to an explosive. But uh, that's not really what I came here to.. say."

Steve has to stop himself from glaring as Peter continues to gaze up at you like you're a goddess, and clears his throat instead. "You need these, right?"

You nod, taking the contracts and look to Peter. "I could get you another shirt, if you'd like? Or maybe just wash this one-"

He nods, stands, slips off his shirt and hands it to you. You blink, cheeks reddening as you take his shirt slowly. "..Uh, yeah, I'll go throw this in the washer and it'll be done in five minutes. Just.. stay here,"

Peter watches as you hurry out of the room, then flops down on to the chair and notices Steve's narrowed eyes after a while.

"What? I call dibs."

"Dibs?" Steve says incredulously. "On my girlfriend?"

Peters facile expression freezes. "Um, what?"

"(Y/n) is my girlfriend so get your own,"

You breeze back into the room, handing Peter an Avengers sweatshirt. "This is all I could find in your size since everyone's either really buff or a female, and since you're neither of those things- oh, crap, wait, I didn't-"

Peter laughs, slipping on the sweatshirt. "It's fine. I may not look strong, but but hey, I could sweep you off your feet, you know?"

And that's when Peter Parker learned that you're very much Steve's girlfriend, because Steve stands abruptly, dips you, and kisses you full on the lips.
