Sebastian Stan (+ characters) Oneshots

I've never done preferences before, so I thought I'd try it out! Hope you enjoy, and let me know if you want to see more of these! Jack and TJ are bi/pansexual in these because I can't say "you can't date the reader bc you're gay" because not everyone reading this might identify as a girl. Sometimes you'll be dating them in these, sometimes you won't, but it won't mention the gender of the reader, as usual.

Bucky Barnes

Bucky tends to get jealous quite often, and he doesn't try to hide it. Usually he would just send whoever was talking to you a hostile and deadly glare, but that didn't always work. Sometimes the guy hitting on you had tougher skin than usual. Sometimes this guy was Tony Stark.

You had been dragged to another one of Stark's parties by Clint, who claimed that you had to get out more and try to have some fun. You knew he was just bored because Nat had gone off on a mission without him, so you had grudgingly agreed to go with him. You didn't have the same luck in persuading your boyfriend Bucky to come along.

Now you stood on the outskirts of the dance floor as you felt your heart jumping with every overpowering bass note that shook the tower. It was almost impossible to see anything in such a dark room, but you were managing just fine. You had been through plenty of missions that required you to be able to maneuver around in pitch black conditions, so this was nothing to you. The only issue was, you couldn't find Clint.

"Did he really ditch me after all of that?" You muttered to yourself in annoyance. Clint was definitely one of your best friends, but that didn't mean he didn't get on your nerves. He was constantly dropping down from the vents into your room at 3 in the morning, waking you up again half an hour after that because he broke the coffee machine and didn't want to tell Tony, shooting arrows with notes attached to them at the walls next to you because he didn't want to yell, and basically any other thing that might cause an inconvenience to you in any way.

"Did Barton ditch you, I'm guessing?" You heard the familiar voice ask from behind you. You turned to face the billionaire and nodded with a chuckle.

"Yeah, he did. I was getting ready to leave, actually," you informed him. This conversation was taking place completely in yells, as that was the only way you could hear anyone over the sound of the music.

Tony grinned and stepped a bit closer to you, his hands in his pockets. "Come on, you can't leave! The party just started. The party won't be the same without that beautiful face of yours in it," he replied in quite a flirty manner. You chuckled and shook your head.

"Nah, Bucky is waiting for me anyways. I texted him and told him what happened with Clint so he said he was going to take me out to dinner," you shot back with a forced smile. You were trying to avoid his advances as much as you possibly could, and you thought that bringing up your metal armed, super soldier, ex assassin boyfriend might get him off your back. You were wrong.

He huffed lightly before replying, "You're still with Frosty, huh? Can't believe you put up with the guy."

You furrowed your eyebrows in annoyance. Tony had never approved of Bucky, but he never said anything like that. Not to you, at least. "I don't put up with him, Tony. I love him. You're the one I make an effort to put up with," you snapped back. You had been very defensive over Bucky as soon as he arrived at the tower, but that protective nature had only grown stronger with time.

Tony began to make another crack about how he could treat you better than Bucky could, but as soon as Tony's hands rested on your waist, a metal hand grabbed him by the collar and ripped him away from you. You gasped in fright at the sudden action, but soon calmed down as you realized who it was.
