A/N: This chapter is going to contain mild smut but some will be smuttier than others.

...

Clint Barton/ Hawkeye

You and Clint were visiting the Tower. While you were there, you snuck away and found a closet to get hot and heavy in. Clint had you pinned against the wall and the clothes were hanging off your frames. In the heat of the moment, you had forgotten to lock the door so when it suddenly swung open, you were totally caught off guard.

"Oh! Sorry, didn't realise this closet was occupied. Can you hand me that broom?" Natasha asked, pointing to a broom nearby Clint. He quickly handed it to her and Nat closed the door.

"Have fun you two!" she called as she walked away. You and Clint returned to your previous actions before you were interrupted.

...

Tony Stark/ Iron Man

You were working on a project with Tony in your studio. He made a few comments, you flirted back, one thing lead to another and well... now you were rolling on the floor, your skin now covered in paint and grease. There was a knock and Steve entered, regretting that he ever did. Steve stood there frozen for a few minutes before you noticed him standing there.

"Hey Capsicle. Wanna take over for me? I gotta tell you though, Y/N's a real handful," Tony smirked.

"Tony!" you scolded, smacking his arm. Steve stood there red-faced and stammering before he finally ran out of there.

...

Pietro Maximoff/ Quick Silver

You and Pietro were fooling around in his old room of the Tower. You were passionately making out on his bed and Pietro's hand slid down the front of your pants. You gasped and moved your hips, greedily wanting more friction.

"Hey Sonic, I- Whoa..." Clint stopped dead in his tracks.

"Get out of old man! I'm busy!" Pietro growled, his hand never stopping its movement. You'd complain as well but you were too lost in pleasure to care.

"Okay, okay, geeze man," Clint grumbled, exiting the room and closing the door behind him.

...

Thor Odinson

Earlier in the day, Thor had been watching you in a LARP battle. The enemies infuriated you and you trashed-talked them quite a bit. The moment you got home, Thor had you pinned against the wall. You took off his shirt and Thor removed your pretend armour. Suddenly, the door opened.

"Hey Y/N, do wanna have a little girl time?" Darcy said as she burst in.

"Oh, I can see you're enjoying sexy time so I'll just go." Once she had left, you quickly locked the door and resumed your previous actions.

...

Sam Wilson/ Falcon

You kissed and licked down Sam's toned chest and stomach. Sam's fingers tangled in your hair as you freed him from his boxers. Before you could go any further, Maria walked in.

"Wilson, Fury wanted me to give you..." Maria stopped midsentence, reports in her hand.

"You know what? I'll just leave these here and you can do them later." With that, she put them on a nearby desk and left and you continued on with your actions.

...

Natasha Romanoff/ Black Widow

Nat had you pinned against the wall, fiercely kissing you. She stopped long enough to take off your top and pinned your arms above your head. Her lips kissed a trail down your neck, occasionally marking you. There was a sudden wolf whistle and you looked up to see Tony smirking at you.

"No, no, please continue, I like to watch."

"What do you want, Stark?!" Nat barked, standing protectively in front of you.

"Meeting in the conference room," he smirked.

"Fine, now go!" Tony just laughed as he walked away and you put your top back on.

"We'll continue this later," she purred in your ear.

...

Bucky Barnes/ The Winter Soldier

You were seated on Bucky's lap as his hands slowly lifted you up and down on him. Your fingers tangled in his hair as he whispered sweet nothings in your ear. Bucky moved his hands up your back to press you against him. Sam suddenly entered your bedroom.

"Hey Bucky, you weren't answering your phone so- Oh!" You turned to see him and blushed, burying your face in the crook of Bucky's neck.

"Get out!" Bucky snapped.

"Okay, I'm leaving. I'll just tell the others that you were busy." Sam left, and you felt totally humiliated.

"Look at me, Doll." You looked up at Bucky and he pressed his lips to yours, making you feel less embarrassed.

...

Scott Lang/ Ant-Man

You were in the kitchen making lunch when Scott came up behind and started kissing your neck.

"Scott, not in here," you giggled.

"Why not? The girls aren't home; we've got the whole place to ourselves..." You gave into him and turned around, kissing him passionately. Scott put his hands on your thighs and you jumped up on the counter. He stood between your legs and you tangled your fingers in his hair.

"Uh..." You broke apart to see Luis standing there awkwardly.

"Luis? What are you doing here?" Scott asked.

"I came to see if you wanted to hang out, but I can see you're busy," he grinned.

"Yeah, so, do you mind?" Luis continued to stand there.

"Luis, if you don't get out of here in the next two minutes, I'm going to tell Kurt you were the one who ate his last Kit-Kat bar," you threatened.

"Bye!" Luis ran out the door. With that, Scott picked you up and carried you to the bedroom.

...

T'Challa/ Black Panther

T'Challa had caught you dancing in your bedroom and his animal instincts kicked in and he pinned you to the bed. Once he got going, it was very hard to stop. You took off his top and raked your nails down his back. T'Challa marked your neck and tugged at your pants and soon things became heated. A servant knocked on the door to inform the king of an important meeting but paused when they heard the sounds coming from the other side of the door. They quickly left to say that T'Challa was currently occupied.

...

Steve Rogers/ Captain America

You and Steve were trying for a baby. Your room was filled with candles, rose petals and soft music to set the mood; the one thing you had failed to do was lock the door. Just as you and Steve had undressed and got under the covers, Bucky walked in.

"Hey Steve, do you and Y/N want to go out to-" He paused when he saw the situation you were in.

"Bucky, love to but we're kind of busy right now," you shooed.

"Okay then, talk to you tomorrow." Bucky closed the door behind him. You kissed Steve passionately, redirecting his focus on making this baby.

...

Loki Laufeyson

You were seated on the counter, Loki's head between your thighs. Your skirt was hiked up to your hips and your underwear dangled from one of your ankles. You were totally at his mercy and your fingers tangled in his hair, pushing him closer to you. Bruce suddenly entered the room to get something and his face went totally red. He quickly left, leaving neither of you none-the-wiser to his presence.

...

Wanda Maximoff/ Scarlet Witch

You and Wanda were making out on the bed that you shared. You had her pinned under you as your hands snaked up her shirt. Wanda gasped in delight and tugged at your top and you took it off.

"Hey Wanda do you know where..." The question died on Pietro's lips as he looked at the two of you feeling a little confused. On the one hand, this was girl on girl on the other, this was his sister.

"Pietro, get out!" you demanded. Within seconds, he was gone. You got up and locked the door before resuming your previous actions.

...

Bruce Banner/ Hulk

You were helping Bruce out in the lab. After a while, you wanted to take a little break. You were in a passionate embrace and Bruce pushed you against the wall, his lips attacking your neck.

"Doctor Banner!" you gasped and clutched at his lab coat as he made contact with the soft point on your neck.

"Hey Bruce, you in here?" Scott asked but stopped when he saw the two of you.

"Sorry, I'll just go," he said, leaving the lab. Bruce pulled away blushing.

"Hey, it's alright Bruce. We can continue this later tonight," you winked, making Bruce's blush worsen.

...

Peter Parker/ Spider-Man

You were at Peter's house watching a movie while Aunt May was out. You kissed him sweetly and he nibbled on your bottom lip. Soon you were passionately making-out on the couch. Just as Peter had pulled you onto his lap, the door opened and Aunt May entered the room.

"Hi kids. Oh, sorry. Just grabbing my purse, don't let me stop you," she said, grabbing her purse and leaving again. You hastily climbed off Peter's lap and sat down next to him, both of you red faced. Peter grabbed a pillow and placed it across his lap, feeling quite embarrassed.
