(: Hey everyone! I was going to post earlier in the week, but I couldn't decide which Stuckony oneshot to post; Fluff or Angst. The decision was made. Angst it shall be. It's not 100% angst though, you get some happiness at the end, where it counts, right? Anyway, I hope y'all enjoy! :)

Tony and Steve were doing really well; communicating and trying to understand each other better. They had their fights and disagreements but they seemed to always work it out eventually.

Then Barnes resurfaced. Tony and Steve fought over it really badly; their worst fight ever, but Tony forgave him because he could lose Steve. He couldn't go without him in his life, he just couldn't. So he went to Wakanda and they talked it out; Steve agreed to come home as long as Bucky could come too and Tony agreed. How could he not?

But as the days passed Steve seemed to get really close to the newbie. After a week Steve stopped coming down to the workshop, he stopped making Tony's morning coffee, according to Friday, Steve rarely even asked where he was anymore. Whenever Tony asked where Steve was Friday always said he was somewhere in the tower with Bucky.

Tony couldn't help but get jealous. He was losing his boyfriend, of many years, to the man that killed his parents.

'He was brainwashed,' Tony kept telling himself, 'He was a victim of Hydras manipulation.'

But that didn't change the fact that his parents were murdered and quite frankly Tony was still upset about it. He set his 3rd empty glass of whiskey down, "Friday, where is Steve?"

"He is in the living room with Mr. Barnes, Sir."

Tony groaned and got up from the bed. That's it, that's the last time he hears Friday say that. Steve is his boyfriend, his and only his. He made his way to the elevator and down to the living room. The elevator doors opened and he walked into the living room, "I-"

Tony covered his mouth as he watched Bucky kiss his boyfriend. He bit his lip as tears filled his eyes as he saw Steve relax into it. He swallowed the lump in his throat before turning around and running down the stairs to his lab.

Steve pushed Bucky away, "That was Tony."

"You don't know that."

"Yes, I do. I've heard him sprint down those stairs too many times to not know that was him. He always has these ideas in the middle of doing something else and he has to run down and get to work." Steve smiled to himself at the thought. His boyfriend was a genius. His smile quickly faded, "He didn't even say anything..."

Steve sighed and Bucky ran his hand across his cheek, "I'm sure it's fine."

Steve shook his head, "Bucky, I can't..."

Bucky backed away, "Is it me?"

"No, it's just that I'm with Tony. I love him. I can't do that stuff with you anymore, it's not the 1949's anymore. I-I know I reciprocated, but it was just because it was familiar to me. I do miss you, I'll always remember back then. But," Steve sighed, "Bucky, what we had back then was amazing. You know I loved you. But now I'm with Tony. I can't live without him."

"Yeah, " Bucky smiled, "I get it."

Steve smiled and hugged him, "Thank you."

~With Tony~

"Friday, check vitals."

"You have an increased heart rate, irregular breathing, and high blood pressure."

"Lockdown. No interruptions, not even Steve."

"Lab is locked down, Sir."

I went to the cabinet in the corner and came face to face with a beautiful bottle of Jack Daniels. I took off the lid and poured myself a glass, downing it in one go.

Why would he... I know that answer. It made perfect sense.

I looked at the small glass in front of me and put it in the sink, looking at the bottle in my hand. I felt my lips touch the top and tilted it back. I took in a few gulps and set it down, putting my hands on the counter and looking at the ground.

I can't believe he... Yeah, I can. I can't blame him either.

I watched as the tears hit the floor and choked on my own sobs. I grabbed the bottle and slid down to the floor.

"Fuck," I said to myself, not knowing why I wasn't at least starting to feel numb yet. Maybe I won't be getting drunk tonight after all.

I groaned and put the lid back on the half-empty alcohol. I sat there and cried for what seemed like forever before picking myself up off the ground and wiping my face with a dirty rag I had laying beside one of my cars.

I had to go talk to him... Tell him it's okay for him and Bucky to be together. They deserve each other anyway... They've waited decades to be together! They deserve it- Steve deserves it. He deserves Bucky.

He knows Steve better than anyone, he will always remember his birthday and he understands the 1940's version of Steve. They are practically the same person!

I stood up and poured another glass, hopping up on the counter to drink it. I looked around my lab and my eyes set on a picture of me and Steve sitting on my desk in the corner. It was us at our coming-out press conference. He told the press he was gay and that he loved me before kissing me in front of all their cameras.

The more I looked at it the angrier I got. Then I was on my feet and making my way to the photo. I knocked it over but it still stared at me from the floor. I screamed and slammed my glass into the picture making glass go everywhere.

"Tony!" Steve's voice came from behind me.

I cried out in pain as blood came gushing from my hand.

"What the hell did you do?"

Me? I did it? Of course, I did. It's my fault. Everything is... Fuck up. I stayed silent as I held my hand to my chest. He tried to help me but I refused to give him access to my injured hand.

I looked up at him as tears ran down my face, "How could you...?"

"How could I do what?" He asked, still trying to take a look at my arm.

"DON'T TOUCH ME!" I screamed. I scooted away as he looked at me worriedly, "You kissed him." His eyes went wide and I continued, "How could you do that?! I brought him here for us! For us to be back to us again! And you make out with him on my couch?! In MY tower! I built this place, I bought everything, I did it for us! For us and the team!"

He nodded and stood up, "We need to talk about this another time. You're bleeding really bad."

"No time like the present, Captain. Besides, I'm fine." I stood up and the room began to spin. "Steve... I... I don't feel..."

And I fell.

I woke up the next day in a hospital. Pepper and Rhodey came to visit, both scolding me and Pepper threatening my life. Still, Pepper kissed my forehead before leaving.

Thor and Bruce brought flowers, I thanked them and they left. Thor wished me good health and Bruce dragged him out so I could rest.

Steve came in after them and set the bouquet of roses on the table next to me. "I guess Thor and Bruce already bought you flowers."

I nodded, "They did, thank you though."

He smiled, "Natasha and Clint couldn't make it. Fury called them in for a mission last minute."

"Natasha hates hospitals anyway," I said. Steve nodded and sat at the foot of my bed. "What are you doing here, Steve?"

"You're my boyfriend, I'm the one who brought you here." He said, "Tony, you had to get 7 stitches in your hand. You have no idea how worried I've been. What were you thinking?"

"I wasn't," I answered, honestly before asking the question that had been burning inside me since I woke up, "Is he here?"

"Who, Bucky?" I nodded, and Steve looked back at the door, "He's in the hallway. He drove us here."

"Let him in." Steve nodded and went into the hallway for a second before returning with Bucky. He stood at the door as Steve took his previous spot on my hospital bed. "Who kissed who?"

Steve started to speak but Bucky interrupted, "I kissed him. It was my mistake and I'm sorry."

Steve shook his head and I let out a small chuckle, "You love him, don't you?"

He looked over to Steve and then back at me, "Of course I do. But it's not the 1940s anymore, he isn't mine and I respect that."

"I have to make this right," I sighed, "Steve, you have my blessing. Bucky, take care of him. He's a reckless idiot."

Bucky shook his head and moved to sit at the foot of my bed opposite Steve. "Tony, Steve loves you. He would have never gone through with cheating on you. I kissed him and he responded, that's all. We're just used to each other, that's all it was. Don't do this to him."

"You must think I'm an idiot," I smiled, "I know the look in your eyes when you talk to each other. You can't be without each other either."

"I can't lose you, Tony. I won't."

"You can't lose him either Steve. You can't have both sides here."

"Why can't he?" Bucky asked. Steve and I looked at him, "Have us both. I don't mind sharing and Steve deserves the best. Who better to give it to him than us, Tony?"

I looked at Steve and back at Bucky, "A three-way relationship." Bucky nodded and I looked at Steve for his reaction. He didn't give me much to go on but I shrugged anyway. "I'm not opposed."

"What?" Steve asked, "You're kidding."

I chuckled, "He's right. It'll be hard but not impossible. Who else is going to give you what we both can? We're the only people you've really ever been with for a long period of time. We are the best of both your worlds."

Steve turned his body to face me, "You're serious?"

I rolled my eyes and beckoned Bucky closer. He came closer and I kissed his cheek, hugging him, before looking back at Steve and beckoning him. He came forward and I kissed him, "I'm serious. It's going to take some work, but  I love you, Cap."

Steve hugged us, "I love you both."

"We love you too." We said in unison.

(: Stuckony anyone? I liked the end, I think had Tony and Bucky kissed lips it would have been too much too fast. They gotta build some trust and love first. Hope you liked it, leave the stars and follow for more! :)
