Some are preferences and others are imagines :)

Tony

It was unlikely that the billionaire would get jealous. He believed he had everything you wanted; money, fame and especially looks.

You were at one of his parties and socialising with all the guests he had invited when you found yourself talking with a man with the last name killian (AN: correct on spelling if you guys want)

"I just think.. why is someone so independent as yourself," he spoke lightly and placed a hand on your tense hip, "working with Mr Stark."

"Sir, I'm not working with Mr Stark," You laughed and successfully removed his hand, "I'm his girlfriend."

"Oh." He smirked and his expression changed into interest, "why someone as stunning as-"

"I hope all is well here." Tony spoke and wrapped an arm around your waist and kissed your temple, "Sorry for interrupting."

"Excuse me." The man said and disappeared into the crowd with you staring after him in confusion.

"Why were you talking with him?" Tony demanded in...jealousy and you smirked.

"You're jealous." You pointed out and turned on your heel to face the flabbergasted billionaire.

"I am-"

You kissed him to cut of his ridiculous lie.

Steve

You were eating a packet of Doritos when you pulled out the perfect chip. Such a petite little chip that you were going to protect from the world.

"Steve!" You cried and he came bounding into the room like an energetic puppy, "I found the perfect Dorito!"

His face sunk like the titanic and you frowned in confusion, it was just a Dorito.

"Look at the proportions." You muttered in awe and turned the chip in your hands. But alas, all was lost when your super soldier plucked the chip from your grasp and shoved it in his mouth.

"No, I'm the perfect Dorito. I'm the alpha Dorito." He mumbled and exited the room with a smirk on his face.

Bruce

It was very unlikely that Bruce got jealous. But when he did, he always informed you and you would back up. Just so a hulk situation didn't occur.

Thor

The God could get jealous of anyone and anything. Apart from your gorgeous twins who you loved just as much as your husband, if not a little more. You even found him jealous of Midgard having that hold over you, always calling you back home.

Clint

You were in the shield base and considering walking outside to catch Clint for a small lunch but you continued to train. You'd find him later on in the day when he was probably less busy with all the avenging things.

"Hey."

You turned and spotted a man who was attending to the gun station and looking over all the guns with awe.

"Crazy how many weapons they have." He mumbled loudly and turned towards you with a grin in his eyes and a confused look on your own.

"I'm David." He introduced himself and walked over so you could shake his outstretched hand. You firmly grasped his large man hand and shook it warmly, unaware of the intentions he had for you.

"I'm y/n." You replied and turned back to the target you had sent over 10 arrows into. You pulled back the string and let it go, remembering all those times Clint had his hands on your waist and whispering into your ear words of encouragement and... Other things.

And of course the arrow sunk straight and true towards the centre of the target where it embedded in its heart area.

"Wow, your good." David said in awe and pushed his black floppy hair out of his eyes, "did you teach yourself?"

You were now aware of how close he had gotten and took a small step back to avoid any awkwardness.

"Actually Clint Barton did." You answered and began fiddling with the bow in your hands.

"Is he your mentor?" He took another small but noticeable step towards you, and brushed a stray piece of hair behind your ear.

"No he's my-"

"Take 5 steps back from my girlfriend before I rip your arm from your socket." Clint boomed as he walked into the room with a murderous aura around him.

David scrambled back and immediately sprinted from the room, not wanting to anger the avenger any further.

"Did he do anything or did he-"

"Clint I'm fine, baby." You laughed and pecked his cheek in thanks, "he just made me uncomfortable."

"I'm going to kill him."

Natasha

She thought guys were going to attempt
to pick you up, performing cheesy pick up lines trying to win you over. So she performed several different kicks, on his head.

Pietro

The Sokovian got jealous, very easily. If anyone gave you a look that seemed flirty or sexual in anyway, there was always hell to pay.

You were currently walking downtown to grab a few things for yourself. Like tampons, hair products and body wash that you liked to chose for yourself. Half way towards your destination you noticed a particular presence behind you that didn't quite go away and that's how you knew you were being followed.

You picked up your phone and dialed pietro, pretending it was a normal phone call like he had taught you to do.

"Hey, just wondering- ugh there's something stuck to my foot hang on." You spoke into the phone with a casual voice and stopped as you were pretending to scrape something from your foot. (AN/ love you spn)

"Where are you?"

"I hate downtown, especially on my way to grab my girly things, everything-"

You were shoved roughly into the nearest alley way where you landed with a thud against the ground.

"I was taught if I wanted to find an avenger," the man spoke and pulled a knife from his belt, "I just have to find someone close to them."

The guy looked familiar in some ways like you'd seen him somewhere before. Maybe Coulson had shown you him, maybe he worked for hydra?

"Who the hell are you?" You asked with a slight sense of amusement to your tone.

"I'm Grant Ward."

Oh. He was kind of important.

"I thought you were gone Grant." You spoke whilst getting to your feet, but you were pushed back down by his booted foot.

"That's what they all-"

He was thrown away by a blue and silver blur that you knew as Pietro Maximoff.

"Stay the fuck away from her." He spat and held grant by his throat up against the wall, digging his fingers into the mans neck.

"She's a pretty thing, I'm sure hydra would have an excellent use for her pretty body."

Pietro growled and with a blur they were both gone. And in the next second pietro was back with fire in his eyes.

"That idiot thinks that he can-"

"Pietro I'm yours."

Bucky

Tony Starks parties were always filled with desperate guys trying to grab a girls attention. Being Tony Starks sister it wasn't really an option to skip one of his favourite parties as your brother would personally escort you to the party.

Currently you were talking at the bar with Natasha Romanoff. Your second favourite assassin friend that you have that you have here in the tower.

You were talking about shield. The training and how she managed to keep her stunning physically features when an arm slipped around your waist from behind and pulled you off your chair.

You knew it wasn't your number one favourite assassin when his left arm wasn't cold and metal. You turned in the jerks arms and saw he had the fancy suit, but total douche bag persona.

"Hey baby." He slurred and trailed his arms down your frame, which you knocked off and slapped him roughly across the face. He jerked back in shock and his eyes harden when he realised what you had done, "you little-"

A silver arm yanked the man back and threw him towards the bar, where he landed with a thump. You spun on your heel and saw your extremely pissed off boyfriend glaring at the guy before turning to you.

His eyes moved over your body like he was searching for something and then you realised he was searching for injuries.

"Buck, I'm fine." You assured and pushed his hands away. But you saw the jealousy flash in his eyes like a fire that looked like it wasn't going away, "I'm only for you. I swear."

Loki

You were doing your daily coffee stop at the little cafe near your apartment. You don't know what you'd do if the cafe hadn't been here during those times when you first met Loki and all he did was keep you up all night talking about Asgard and complaining about Midgard.

"That'll be $3.50." The cashier said and winked at you when you handed him the money. Flirt.

"I'll call out your beautiful name which is...?"

"It's y/n." You answered with as little flirt as you possibly could. Which was really difficult considering this guy thought that everything you were doing was flirting.

You waited for your coffee and replied to a few messages on your phone before your name was called out. You gratefully accepted your latte and looked at the cup which had a number on the side and a guys name. You remembered seeing it on a name badge earlier.

With a heavy sigh you walked out of the small café and started back towards your apartment, coffee and number in hand. You arrived at the large apartment complex and started up the steps to the front entrance when the coffee was plucked from your hand by a set of familiar slender fingers.

"Loki." You groaned as you saw him inspecting the number on the cup with narrowed eyes, etched with anger.

"What is this?" He asked with right facial features and fire burning in his eyes.

"Some idiot decided to put his number on my cup." You replied and yanked the coffee out of his hands, taking a sip and sighing in pleasure. That hit the spot. You looked at Loki over the top of your coffee and saw him frowning at the number with... Jealousy.

"Someone's jealous!" You pointed out and waved your index finger at him, teasing him and trying to find his breaking point.

"Am not." He gritted his teeth and you let out a little giggle and kissed his cheek.

"You won't have to worry about a guy from a café, I much prefer the God of mischief."
