Natasha's POV

All I heard was my own breaths. All my focus was on my own breath. I knew my body did as I commanded it to. My feet didn't make a sound as I quickly walked through the corridor, careful not to be seen. Or heard. My breaths was all that could make them notice me. I held the object steady in my hand so that I wouldn't drop it. As much as I tried, I couldn't take of the smirk on my face. I stopped for a moment as I reached the end of the corridor and carefully looked around the corner. They were all sitting in the sofas. Bruce, Tony, Thor, Steve and Clint. To my luck, Clint was sitting with his back against me. Suddenly Steve's eyes met mine and I was surprised at how quickly he had noticed me. It almost made me angry. I gave him a serious look and put my finger to my lips, hushing him from saying anything. He played along the best he could. He wasn't really made to be an actor if I put it that way. The others were busy talking and I slowly, quietly stepped towards them. Towards Clint. I held the plate with whipped cream steady in my left hand and creeped up behind Clint before I quickly smashed it in his face. He didn't react at first. He sat completely still as the other avengers just stared at him. Everyone of them wearing a smirk except me. I finally managed to hold it in. Clint slowly stood up and turned around.
"Natasha." He said as some whipped cream fell from his face to the floor.
"Clint." I said as my serious face slowly disappeared into a big smirk. We were all quiet for a while. They sat in the sofas watching, trying not to laugh as Clint and I stared at each other.
"No strawberries?" He asked and I raised an eyebrow.
"Are you in a porn movie?" I asked and he smirked as he started to dry of the cream from his face.
"Your getting back." He said more seriously as I cracked up in laugher.
"Good luck with that." Tony muttered and I saw Steve nod along.
"This is the tenth time this week and you haven't managed to get back at her once." Bruce said and I sat down pleased in a sofa as I licked of a little whipped cream from one of my fingers.
"Oh I will." Clint said as he dried of his face with some paper he had found.
"I'm starting to enjoy this April fools thing is it?" Thor said and Steve laughed.
"It's usually just the first day of April. Not the entire month." Steve said and looked at me with a smile. I smirked back at him.
"A whole month is so much more fun." I said and Clint grunted.
"Yeah I don't know about that." He said and I chuckled.
"I'm just happy we aren't involved." Steve said and I looked at Clint who already stared at me. He gave me a smirk and I smirked back.
"What's that look?" Tony said worryingly.
"Yeah I think we just got involved." Bruce said nervously.
"And I think it's Cap's fault." Thor said and I looked at Steve.
"Shit, I'm in trouble." Steve said.
"Language." We all said and he sighed.

It was finally official. I could prank anyone I wanted. And I knew just who to pick as my victim. Steve had surely missed a lot of April fools and I just wanted to be kind and help him live out the ones he missed during his sleep in that ice. Or I just liked to pick the most kind one's since they always got away.
It was late. Late enough to be in deep sleep. I picked up the enormous back and silently walked outside the door. We were all living in the avengers tower together. It made it all very easy. Almost too easy. I took the elevator to Steve's floor and cracked his door open as quietly as I could. I had only been inside his apartment three times before but I knew my way around. It was dark and quiet. I sneaked towards his bedroom door and slowly opened it. Steve was laying on the bed, asleep. All he wore was a pair of grey pyjamas pants and I studied him for a while. I wondered what he was dreaming about. He looked extremely comfortable, and hot. I suddenly realised why I was there and turned to the closet in his bedroom. I quickly took out all his clothes, which wasn't all that much) and replaced it with knew ones. I smirked at the sighed of his closet before I closed it and taped up the note on it. I took the bag with his clothes in my hand and looked at Steve again to make sure he was sleeping before I slipped out of his room and went back to my apartment.
This was going to be hilarious.

Steve's POV

I woke up to another dream about Natasha. She showed up in my dreams pretty often but this one had felt different. I sat up tiredly in my bed as my new woken eyes were drawn to a note on my wardrobe. I quickly went out of bed and grabbed the note which had been taped to the wardrobe in a perfect way.

I thought you needed a change of clothes. It will suit you perfectly.
Your turn, Rogers.

I realised it was from Natasha right away. There was three reasons for that. She was the only one to talk to me like that, she was the only one that would manage to sneak into my bedroom while I was asleep and her handwriting is pretty easy to remember compared to the other fours.
I opened the closet and was almost taken back at the sight. The whole wardrobe was full of clothes. Neatly put on the hangers and fold on the shelves. There was only one problem, all clothes were America related. There wasn't a single clothing without the American flag or its colours. I put my hand to my forehead and laughed.
"Clint gets whipped cream and I get this?" I said to myself as I stated forward.
"Oh God." I said as I realised even my underwear was gone and replaced with underwear with American flags. I sighed and started to dress.

When I walked out to find Natasha, I was greeted by them all in the sofas. As I stepped inside, Natasha took a few pictures of me and laughed. I had tried to pick the least American outfit which was hard. I looked like the American flag. There was nothing more to say.
Tony and Clint cracked out in laughter as Thor and Bruce smiled at the sight. I looked at Natasha and realised she was wearing one of my shirts.
"I need my clothes Natasha." I said, trying to sound serious.
"Isn't the clothes your wearing enough?" She asked. "A true patriot." She said and Thor and Bruce started laughing as well.
"Give me my clothes Nat." I said with a small smile. "Or you'll get back."
"I look forward to it." She said with a smirk and I sighed before I sat down at the sofas. "Stop it." I said as I looked at Clint and Tony who was still laughing their asses of. I then turned my looks to Natasha and she still had a smirk on her face.
"Your not getting away with this. I have meetings today." I said to her and Natasha's smirk burst into a smile.
"I know. I'm going on them too." She said while looking in a magazine.
"You took my shirt." I said and she looked at me with a raised eyebrow.
"Borrowed. Like I did with the rest of your clothes. You'll get them back when you learn something about revenge." She said before she turned back to the magazine again. It looked like she was reading it but I think she found it boring since she just kept changing page.
"Good luck Steven." She said as I stood up. I walked away with a smile on my face as I heard her voice again.
"Are you wearing the underwear too?"

Natasha's POV

I changed page in the most boring book I had ever read. I was deadly tired but I refused to go to bed again after the last dream. And the dream after that. It all comes back as I close my eyes so I try to avoid it.
Suddenly I hear something outside my door and I put down the book and turned of the lights. I moved to the dark corner and watched the door. I wasn't scared, only curious on which of these morons it was that was trying to break into my apartment. The door opened and to my surprise, it wasn't Clint that I would have betted on. It was Steve. I frowned but smiled as he looked around. It almost looked as if he didn't even know what to do. But I knew what he was looking for, his clothes. I smiled as he awkwardly searched his was around the apartment, too polite to actually touch anything or look around too much. He found his way to my bedroom and hesitated before he looked inside. He probably expected my sleeping body in there but he was wrong. As he realised that I wasn't sleeping in my bed, he opened the door a bit more to make sure.
"You found your way to my bedroom quickly huh?" I said and he turned around with wide eyes. I gave him a smirk. "I'll admit your good looking but I'm not interested. At least not tonight anyway." I said and he sighed as he dragged his hand over his face.
"I'm sorry Natasha. I only wanted my clothes. It's been a week." He said and I chuckled.
"No kidding." I said as I walked back to the couch. I turned on the light again and sat down with the book. Steve followed me to the living room but didn't sit down.
"I only need a pair of jeans and a shirt. I'll keep the socks and underwear." He said desperately and I smirked.
"You really like those underwear huh? I'm convinced they suit you good." I said and he chuckled.
"Natasha please." He said and I shock my head.
"Revenge, Rogers." I said and he sighed.
"Revenge isn't my thing." He said and I laughed as I kept pretending to read the book.
"No kidding." I mumbled.
He sat down on the floor against the wall and I looked at him.
"What are you doing?" I asked and he smiled in a cute way.
"I'm staying until I get my clothes." He said as he looked around the apartment a little more closely from his seat. It made me worried as no one ever even was inside here.
"Suit yourself." I said as I turned back to the book without being able to read it. Not only because of how boring it was, but also because of how Steve's eyes kept pacing around the place I depended my alone time.
"Why are you awake anyway? It's in the middle of the night." He said and I sighed.
"Mind your own business Rogers." I said and he chuckled.
"Oh really? Being grumpy now are we?" He said and I put down the book.
"I'm simply not tired." I said and he nodded.
"How's my shirt?" He said with half a smirk and I looked at what I was wearing. "I see it's another one."
"Don't worry Rogers. If you want to borrow a dress, you can just ask." I said and he nodded.
"Good to know. Can I take some water?" He asked and I nodded.
"Well, suit yourself." I said as I turned to my book again.
I changed page once again as I saw Steve's reflection in the TV. He was holding a bowl of water and I waited for the right moment. Right before he poured it over me, I stood up and grabbed the bowl. I pushed it towards him and he ended up soaking wet as the bowl hit the floor with a crash. Glass spread out over the floor and I looked at Steve with raised eyebrows.
"That was the worst and most obvious prank I've ever witnessed." I said and Steve chuckled.
"I don't do pranks." He said as he drew his hand through his wet hair.
"Well, at least you tried." I said, biting my lip a bit. "Take of your shirt." I said and he looked at me.
"What?"
"I said, take of your shirt." I said again.
I went into my bedroom and took out a shirt and a pair of jeans from the bag I had hidden below my bed.
"I'm only giving you one shirt and a pair of jeans. Mostly to make you go away but it was a nice effort." I said as he dragged of his shirt. I felt my stomach twist in a weird way as I once again saw his bare chest. I threw the clothes and a towel at him and he smiled.
"Thanks." He said as he dried himself with the towel and put on the new shirt. He then began to clean up the water and the glass from the floor.
"It's fine, you can leave it there." I said and he shock his head.
"It was my fault." He said and I nodded in agreement.
"Yes it was." I said and he laughed.

• • •

"I'll buy you a new bowl." He said as he threw the glass pieces in the trashcan.
"Goodbye Steve." I said as I stood by the door.
"And I'm going to fix the door." He said as I looked down to the badly broke lock.
"Goodnight Steve." I said again and he smiled.
"Goodnight Natasha." He said as he walked towards the elevator.
I watched him for a few second before I closed the door.

Steve's POV

The next day, I woke up and was even more tired than when I had gone to bed. I rubbed my eyes before my eyes yet again was drawn to the wardrobe. I stepped out of bed and took down the note. It was much longer this time.

I felt like you've been punished enough. There's even some rumours going on about you now and yes,
I started them all.
And to show how sorry I am about that, you'll get your clothes back.
Except for four shirts.
And your underwear.
(I still believe the new ones suit you much better)
I'm waiting for that bowl.
/Nat

I opened my closet and was relived to see my old clothes back to place. She had though, left four American themed shirts and all the underwear, like the note said. I smiled at the thought of her in either one of my four missing shirts.
They suited her well.
