I got offered the job! :D Still don't own Marvel though.

This was a request by @idontrllyknownow I hope you enjoy!

Warnings: ages are just all messed up. They are all ranging from 13-17 years old. Also, I know you said 'sibling relationship,' but...Parley...

Harley, Peter, Shuri, Lila, Cooper, Cassie, Nate, and Morgan were all gathered around a table at the library, speaking in hushed voices.

"Little Morgan probably couldn't handle it." Nate declared.

"I'm not little! I'm 13. And you are only half a year older than me!" Morgan stuck her tongue out.

"Okay guys." Harley, the oldest, spoke up. "You both are little." He stuck his tongue out.

Peter sighed. Sometimes, he didn't know why he hung out around this group. They all knew each other—something about family friends—and Peter was left to keep them all in check as the surprisingly most mature of the bunch. "Everyone shut up." Everyone listened. "We aren't watching It."

Shuri opened her mouth to protest.

"Nope." Peter cut her off. "I don't care. I can't watch that. If you want to, do it on your own time."

The other kids shared a look and unanimously agreed. Peter couldn't handle It. He was too sweet.

Harley blushed when Peter looked at him. "So, what else do you have to watch?" Peter asked.

"Ummm...we could watch—" Harley didn't know. His plan to watch a horror movie and comfort Peter was just foiled, so he had to think of something else, and quick. "Something Disney?" He asked.

Peter's eyes lit up. Shuri rolled her eyes at Harley, seeing what he was doing.

"I love Disney!" Peter squealed. A librarian gave him a fond glare, but Peter just waved and smiled and she looked away.

"I love how the librarians love you." Lila commented.

Cassie laughed. "Everyone loves Peter."

"Everyone except Flash." Cooper growled. The rest of the kids mimicked his protective and and angry face. Even though Peter was the second oldest after Harley, everyone was a bit protective of him. Peter just rolled his eyes.

"Guys."

Cooper sent Peter an apologetic look, and they went back to discussing movies.

"So, is everyone cool with Disney?" Harley asked. Everyone nodded, Peter a bit more enthusiastically than the other. "Okay. Let's go. I'll drive."

Everyone clambered into Harley's giant SUV. He claimed his Dad got it for him when he found out he had so many friends. Harley and Peter sat in the front, the Barton's in the middle, and Cassie, Morgan, and Shuri in the back.

Harley parked outside the tower and turned to Peter, whose eyes were wide.

"So, you know how I said we could go to my house?" Harley asked conversationally.

"Mhm." Peter hummed distractedly.

"Welcome to my house..." Harley trailed off as Peter turned to him.

"You're telling me," Peter clarified, "that I've known you for almost a year, and you never thought to tell me you lived at Avengers Tower?!?"

"To be fair," Morgan piped up. "I do too, and the rest of these idiots visit pretty often."

Peter just looked around, question marks practically visible in the air above his head.

"Morgan and I were adopted by Tony Stark. Lila, Cooper, and Nate are Clint Barton's kids—Hawkeye." Harley started to explain. "Cassie is Antman's kid, and you already knew Shuri is the princess of Wakanda."

Peter shook his head. "Fine. Cool. Okay. My friends are the Avengers' kids. Whatever." He mumbled and got out of the car. "I was told we were watching a Disney movie!" He called when none of the other kids followed him.

They all scrambled out of the car, and Harley led Peter inside. The rest of the kids trailed along behind Peter, scared that he was randomly going to explode on them about secrets if they were too loud or something. As they entered the elevator, JARVIS greeted them and took them upstairs. While still in the elevator, Peter started to talk.

"You know, while we are on the subject of secrets," Peter stuck his hands in his pockets. "I'm Spider-Man. Don't tell anyone."

Before anyone could protest, the elevator dinged and Peter strolled out as confidently as if he was in his own house. Harley scrambled after him.

"Peter! You can't just—"

Peter turned around and smiled at him, and Harley's breath caught in his throat.

"We can talk about it later, but I was promised a Disney movie." Peter said calmly. Harley and the rest of the kids dragged their feet to the movie room, Peter following Harley and grinning like an idiot.

The group got settled. The Bartons laid on the floor with Cassie and a bunch of pillows, and Morgan took the lone seat to the right of the TV. Shuri took the couch and Harley sat down next to her. Peter happily plopped down next to Harley, practically in his lap. Harley's face was bright red.

By the end of a Disney marathon, Peter was curled into Harley's chest, fast asleep. Everyone else was still awake and teasing Harley for his bright red cheeks.

Then, the elevator opened. A bunch of tired Avengers trooped in and greeted their kids. Tony stopped when he reached Harley. "There's an extra..." He muttered.

The kids laughed, and Harley adjusted Peter on his lap. "This is Peter." Harley whispered.

"Oh!" Tony's eyes widened, then he smirked. "This is the famous Peter, huh?"

Harley blushed harder if that was even possible. "Shut up." He grumbled.

"Okay." Tony pulled the Avengers out of the room, probably to go gossip about Harley's love life.

Eventually, everyone else fell asleep as well.

-~-~-

The next day, Peter woke up held securely by Harley. He lifted his head and smiled at his peaceful face. Gently, nervously, he pecked Harley's cheek.

Harley slowly woke up. "Hmm?"

"Hey, Harley." Peter whispered, a light blush dancing across his face. Harley's fave instantly lit up bright red and Peter laughed softly.

"Ummm...Peter?" Harley wrapped his arms around Peter's waist when he tried to get up. Peter placed his hands on Harley's chest to balance. "Will you be my boyfriend?"

Peter smiled brightly. "I thought you'd never ask." He kissed Harley softly.

Suddenly, a round of catcalls and whistles sounded from behind them. Peter sucked his head in to Harley's chest and blushed. Harley blushed too, but he decided he'd be better off glaring at his family.

Harley stood up and steadied Peter next to him with an arm around his waist. "Dad, Uncles, Aunt Tasha." He greeted the Avengers, who were all smirking. "Meet my boyfriend. Peter Parker."

"Hi." Peter waved shyly. Tony opened his mouth, but Steve elbowed him.

"He's dating your son. Adopting him would be weird." Steve said.

Tony closed his mouth.

"Hi, Peter." Bruce said kindly. Peter's eyes got really wide and he tugged on Harley's shirt.

"Harley!" He whisper-shouted. "Bruce Banner said hi to me!"

Bruce blinked. Hayley laughed. "I know, Peter."

Peter rushed forward and shook Bruce's hand. "Hi, Dr. Banner. I'm a huge fan of your work. Your research into the physics of subatomic particles is groundbreaking."

Bruce smiled brightly. "I'm glad to meet a fan."

Tony opened his mouth again. "Are you sure—"

"No, Tony." The other Avengers chorused.

Natasha sashayed up to Peter. "You're my kid now. You can call me Nat or Tasha."

Peter grinned. "Okay, Nat."

Tony pouted. Harley laughed.

The End.

I hope you enjoyed!

Bye!
