Ever since Peter met Shuri when visiting Wakanda for the first time with the Avengers for a meeting, they had been best friends.

They had a lot of things in common- a love for science, a love of pranking, and of course-

Vines. 

"Hey I had this idea," Shuri said, spinning in her chair as Peter fiddled with something in her lab. 

"Yeah?" Peter replied, glancing up from his vibranium webshooters. 

"What if we had this concept that whenever either of we begin a vine, the other has to finish it, no excuses." 

Peter nodded. "So if I said 'what are those?!' Then you would have to say-"

"These are my crocs." 

Peter beamed at her. 

"And if I said 'this b*tch empty!' Then you'd have to say-"

"Yeet!" Peter chucked the screwdriver in his hand across the room. 

Shuri cracked up laughing, clapping her hands as Peter realised what he'd just done, and ran over to retrieve it. 

"Oh this is going to be fun..." 

*-*-*-*-*-*

It was only the next day that Peter was eating breakfast with Shuri on the roof of a random building, watching a couple of children play a game with a ball that Peter didn't know the rules to, but Shuri obviously did, yelling at them to get their heads in the game. 

Peter had just bit into a bun, mouth full, when Shuri turned to him with a smirk that meant nothing good. 

"Jessica, I saw you hanging out with caitlin yesterday." 

Peter, whose mouth was still full, had to attempt to reply with a full mouth. 

"R-rebecha ibs not whad you fink." Food sprayed everywhere, and Shuri started laughing again. 

"I won't hesitate b*tch!" She said, through her laughter. Peter started giggling because Shuri was giggling, and began choking on his food. He ended up spitting it into a napkin so he could breath again. 

Later on, during dinner with T'Challa and the Avengers, Peter looked at Shuri slyly as she sipped her water. 

"This b*tch empty." Peter whispered. Shuri lowered her glass and looked at him, horrified. 

"Please don't." She whispered back, looking at the glass in her hand. 

"This b*tch empty." Peter repeated. 

"I am so gonna get you back." Shuri hissed, raising her arm hesitantly. "YEET!" 

Everyone ducked as she yelled it, and turned around or stood up as her glass hit the wall and smashed to a million pieces. 

"Shuri!" Scolded her mother, standing up at the head of the table. 

"Sorry Mother." 

"Go clean it up this instant, you are to finish your dinner in your bedroom." 

"Yes mother." 

Peter felt rather guilty, until Shuri looked at him over her shoulder and mouthed- 

'Did you see T'challa's face?' All while grinning, her dimples on show. 

*-*-*-*-*-*-*-*-*

The next day Peter was due to go home, and so he stood in front of the quintet, watching his family bid goodbye to T' Challa, Shuri and their mother. They were all pretty respectful with it, though Bucky exchanged a hug with T'Challa and fistbumped Shuri because he had grown rather close with them while he was staying in Wakanda. 

Eventually T'Challa, Shuri, their mother and Okoye got to Peter. 

Peter shook T'Challa's hand. 

"Do not get into too much trouble back in America, eh?" T'Challa said, grinning. 

"I'll try." Peter replied, smiling sheepishly. 

"He's right, I don't want any texts about you slamming into a building and breaking your nose again, or falling out of a tree while saving a cat or-"

"I get it I get it, I said I'd try-" Peter interupted, laughing, accepting the tight hug Shuri gave him. They pulled away and did their secret handshake. 

With that, Peter headed to the door of the quinjet.

"Hey Peter can you hold this?" Steve asked, holding out his shield as he dug through his bag to check he had something. 

"Sure!" Peter chirped, looking at the shield, awestruck. He ran his fingers over it. 

"Hey Peter!" Shuri yelled from where she watched with T'Challa and her mother. "This b*tch empty!" 

"Shuri!" Shuri's mother scolded. 

Peter looked at Shuri then down at the shield in his hands in dismay. 

"Yeet?" He said, knowing he would get in trouble, and threw the shield with such might it flew an ovals distance away, rolling around like a frisbee before falling to the ground in the distance. 

Everyone stared at in silence for a few seconds. 

"Well you're gonna have to go get that now. Go on, go get it." Tony said, clapping Peter on the shoulder. Peter winced, and dejectedly began jogging over to the shield. 

"Faster! Faster Peter!" Tony yelled. 

"Yeah Peter!" Shuri yelled, grinning. 

"Oh stuff you Shuri!" 

"I love you too!" 

Eventually Peter arrived at where the shield lay and picked it up, waving it at the Avengers in the distance. 

"Great, bring it back!" Tony yelled, cupping his mouth with his hands. 

"whAT?!" Peter shouted. 

"BRING IT BACK!" 

Peter held it like a frisbee, then frisbeed it in the wrong direction, everyone watching as it flung sideways. 

"What the f*ck Richard?!" Bucky and Shuri said at the same time. Everyone looked at Bucky, and Shuri cried tears of joy. 

Realising everyone was looking at him, Bucky glanced back. "What? She visited me all the time when I was here and taught me all about this century, and I live with him for f*cks sake, they taught me vines to use in situations like this." 

Tony turned away. "For f*cks sake Parker," he grumbled. "Corrupting everyone. First me, now Barnes..." 

Meanwhile, Peter was jogging over to the shield, which was now stuck in a tree. He stopped at the base and looked up, and Tony realised before the others what he was about to do. 

"Peter DON'T YOU DARE-"

Peter being Peter, did it anyway. 

He began climbing the tree with ease, up the trunk and to the topmost branches, which swayed in the wind. He grabbed the shield, then realised just how high up he was, and how brittle the branches were. 

He didn't even have time to grab the trunk before the branch beneath him snapped and he tumbled to the ground. 

"Oh for Odins sake Peter I will kill you..." Tony murmured, activating his suit around him and jetting over to where Peter was currently sitting up and holding his head with one hand, trying to shake away the dizziness. 

Steve ran after him too, as well as Bruce, Natasha, and Shuri. 

"You're an idiot Peter." Tony said as he knealt beside him, checking his face all over with his hands. 

Peter tried to pull away, but Tony was strong. 

"I'm fine dad I only fell I've fell from bigger heights before-"

"I don't even want to know Peter." Tony sighed, moving out of the way as the others arrived. Shuri was filming. Peter suspected she'd been filming since she quoted the vine. 

"How do you feel Peter?" She asked, zooming in on his face. 

"Like shi-" Peter caught the eye of a dissaproving Steve in his natural habitat. 

"-p. I feel like ship."

"And how does ship feel?" 

"Like the titanic when it sank. I got the shield though!" Peter brightened, looking for the shield around him and lifting it up once he did. 

"Ayyy! Good job!" Shuri high fived him. 

"Come on let's get back to the jet," Natasha said. "I wanna watch Avengers Civil war on the jet and see if it's accurate as to what happened." 

"It isn't." Shuri told her. "It's pretty cool though." 

Peter nodded from where he was currently thrown over Steve's shoulder, looking at them as he poked Steve's back. 

"Stop poking me Peter." 

"I'm not that's Dad." 

"Don't even try, he jetted himself back to the quinjet ages ago." 

"Well unlike you, I'm not AGES years old so how would I know?" 

"Don't be a smart alec." 

"The whole point of going school is to learn to be smart how can I not?" 

"Just... stop." 

"I can't stop unless I die, because the heart can't be stopped at will-"

"Yes it can." Shuri said, grinning. 

"Please stop with the suicidal thoughts." Bruce told them. "It's not healthy." 

"Your not healthy-"

"Right, that's it I'm taking away your snacking privileges on the jet." Steve interupted. 

"Whatttttt you can't just let me starve that's child abuse!" 

"It's only a few hours, you'll survive." 

"Hello! I have fast metabolism I will die quickly without food!"

"No." 

"Pleaseeeeeeeeee?" 

"Nope."

"I'll tell dad!"

"You know what, you're gonna have a nap on the plane." 

"But I don't want a nap! I wanna watch civil war with Auntie Tashaaaaaaa!" 

"Shhh." 

 *-*-*-*-*-*-*-*-*-*-*-*

Through many visits, holidays and Skypes, the adults began to catch on to the tradition the two had started, and suddenly nobody wanted to be in the room when both of them were together. 

But of course, someone had to be there to tackle either of them to the ground everytime someone said 'this b*tch empty' because every single time without fail (even when Peter broke his arm) they would throw something, and often, that was something incredibly important such as a chemical or experiment or beaker of acid they were holding. 

One time Peter managed to throw a highly corrosive acid at the wall and burn a hole through it. 

That had resulted in the ultimate punishment- cleaning the entire communal floor. 

That of course meant he scrubbed every single thing on the floor clean, including the avengers bedrooms if they wished. 

Thor's was always the worst- Peter had three buckets of laundry to do for him, and found a dead warthog beneath his bed. It stunk so much Peter was pretty sure he lost his sense of smell by the end. 

It was quite a dangerous job cleaning the tower, for with so many assassins and warriors living in just one place, there was so many weapons hidden just out of sight. 

While cleaning the couches, Peter cut his finger on a dagger Natasha had his down there. Another time Peter accidentally set off one of Clint's booby traps and almost got impaled in the heart by Clint's arrows and had a bullet skim his leg. 

Booby traps were banned after that. 

Weapons weren't, evidently, for Peter found six guns beneath the sink, ten daggers in the ceiling, five arrows in the vents, and several bombs in various cupboards and drawers that wouldn't go off unless provoked or set. 

Bombs were banned after someone hid one in the oven and nearly blew apart half the tower. 

While that hadn't been fun, Peter got fast food for dinner for a week before they managed to replace the kitchen, so that was great. 

Thor also tended to hide his preferred weapons around the tower- massive axes were placed on the hooks by the door made for hats or scarves, and there was several asguardian swords lying around like they were some sort of decoration. 

He also left Mjølnir around, mainly for the purpose of tripping people when they were in a hurry or weren't looking where they were going. 

That backfired when Peter stole it and tried to sell it on eBay to get money for yet another back pack (he always seemed to forget that Tony was a multi billionaire.)

It was one time that Tony believed the game had gone too far, and many would have agreed if it wasn't so funny. 

Peter, Shuri, Ned and MJ went to the gym in the tower- suspicious in itself seeing as the amount of times the teens had complained about how sport class should die and burn in Hell for all eternity. 

They set up their cameras, and the rope. 

Peter held onto one end, and MJ, Shuri and Ned held the other end. Shuri had on her tech glove things to give her extra strength as well. 

In a few seconds, Peter was in the air, flying by the rope and- hit the ceiling, dislodged some of the ceiling and fell back down again.

It was exactly like the vine, but, being exactly like the vine, it was also very painful. 

*-*-*-*-*-*-*-*

"Concussion, broken arm and twisted knee. Should heal itself by about three days time." Bruce said, finishing his examination of Peter. 

Peter was currently wanting to sleep, but nobody was letting him, for Shuri had posted it on social media and it was blowing up his phone, as well as the picture she posted of the aftermath- Peter laying in a hospital bed with bandages and being lectured by several people at once. 

Tony was first to lecture him, yelling for a bit about recklessness, then Steve gave him stern words, then the others came in to tell him it was awesome but don't do it again because if Tony dies of a heart attack who's going to pay for everything for them? 

After much medication, Peter finally got his beauty sleep, and when he awoke, he had the smell of caramel and chocolate chip cookies and several Disney movies, as well as his friends awaiting him. Shuri and MJ had also stolen his pyjamas- avengers themed of course- and some of his hoodies, such as his Spider-Man hoodie that MJ was currently wearing. 

It was fun. 

The end cos I can't be bothered and I'm tired goodnight.
