Sebastian Stan imagines!

She's mine, Captain.

Setting: 2 years after CW.

"We don't have to go if you don't want to, Y/N." Bucky, your boyfriend of two years was being thrown a birthday party by the team, and you had just come back from a tough mission.

"James Buchanan Barnes, I wouldn't miss this if Sebastian Stan walked through that door right now."

"Sebastian Stan?"

"No one. Come on."

"Ah, the man of the hour!" Bruce clapped as Bucky walked in. Which lead to the rest of SHIELD in clapping as well. "Happy Birthday, Bucky." Bucky's smile was genuine when Steve and Banner came up to hug him.

Bucky and Bruce had bonded over the thought of them both losing control at random times with triggers. Whether they were words or dreams. When you lost control you had no option. And they helped each other. It was nice when you weren't exactly in a place to help Bucky if he'd had a nightmare.

"You really should sit down." Bucky pleaded, helping you over to a couch. "You really should stop worrying about me and enjoy your party."

"You have four broken ribs and a fractured leg. Darling, I'm surprised you convinced me to come and bring you."

"You're so over protective." He kissed your forehead. "Only for you..and maybe Steve."

"Oh, I know."

Whilst Natasha had convinced Bucky to leave your side for a moment and say hi to guests, Steve had made his way over to you and began to take away some of your boredom.

"You and Bucky are good?"

"Going two years strong, Cap." You smiled, rubbing your healing ribs softly.

"I'm glad you guys found each other. You guys are basically soulmates." You smiled bigger. Bucky was everything to you, and the fact that others could see it meant a lot.

"Yeah. I'd like to think of it that way too." You winced as a sharp pain, spread throughout your chest.

"Steve, I think I just re-broke my rib." Looks like having super strength had its draw backs.

"Do you need me to get Bucky?"

"I need you to get me to the infirmary, let him enjoy his party." Steve easily escaped the party and got you upstairs, and into the infirmary. Some nurses had stayed on duty, knowing there would be drunk agents showing up to sober up before going home to their families.

"What happened?" Your nurse asked, she looked worried at the amount of pain you were in.

"Super strength. Tried to ease some pain. Didn't go so well." You kind of screamed as she lifted your arm and the last thing you saw were Bucky's worried eyes.

Morning.

You groaned. The pain either hadn't subsided or the morphine wore off. You decided to go with drugs.

"Hey, Y/N." You looked over to see Bucky in a chair beside you. "You look hungover."

"Indeed, Doll." He smiled despite the pounding that was probably in his head.

"You passed out when I got up here but, Steve told me that you wanted me to have fun. So I did."

"Not too much fun, right?"

"Not so much that I was unfaithful to you, no." Just as you were going to pull Bucky to you and kiss the life out of him, Steve walked in.

With stitches.

"Hey, Y/N."

"Tried to kick your ass for thinking about cheating didn't he?"

"Yup." Bucky smiled sheepishly.

"I told you. She's mine, Cap."
