Word Count: 1,156
Genre: Platonic, f1 x fem!reader (platonic)
Summary: You’re Y/N Piastri—Oscar’s youngest sister, Australia’s Olympic volleyball golden girl, and possibly the loudest person to ever enter a paddock. Somehow, despite not driving, you’re everyone’s favorite chaos dealer. Featuring banter, sibling shade, team bonding, and volleyball supremacy.
Warnings: Swearing, crack-level energy, mentions of nerves/anxiety in competition, found family tropes, protective driver squad energy.

“You’re Oscar’s sister?”
Carlos Sainz blinks at you like you’ve just said you were raised by wolves.
You raise an eyebrow, volleyball duffel slung over your shoulder, Team Australia jacket half-zipped, hair in a messy bun still flecked with sand from your morning drills. “Unfortunately. Why?”
“No reason,” Charles mutters, already backing away slowly like he’s about to witness a crime.
“No no, let’s hear it, Leclerc,” you call after him, stepping into the McLaren hospitality like you own the place. “Go ahead and tell me why every single one of Oscar’s coworkers looks personally betrayed that I exist.”
“We just… assumed he didn’t have siblings,” Ollie Bearman offers, popping up behind you with his usual baby golden retriever energy. “Or like, if he did, you’d be more…”
“Quiet?” you finish.
“Yeah,” Ollie says, and then realizes his mistake. “I mean—”
↳ You’ve been to exactly three F1 races before. This is the first time people are aware you’re that Piastri.
You went viral after the Australian Olympic committee posted your locker room hype speech before the women’s volleyball team beat Brazil in the finals last year.
Now, somehow, you’ve become the unofficial chaos courier of the paddock.
Kimi Antonelli [texts you at 1am]: Are you awake
You: when am I ever not??
Kimi: charles won’t stop stress-folding his underwear
You: omw
THE FIRST TIME YOU MEET THE WHOLE GRID (aka unsuspecting victims):
You’re only in Monaco for Oscar’s birthday and McLaren’s team dinner.
But then Lewis Hamilton hears you’re there and suddenly everyone wants to meet “the Olympic one.” You assume it’s because they’re curious. Turns out it’s because Oscar’s been lying through his teeth for years about having a “normal, quiet little sister.”
Turns out: you are not normal.
Or quiet.
Scene: Red Bull Motorhome, Post-Qualifying
Oscar qualified P4. You’re proud. You also absolutely grilled him on his sector 3.
“Mate, did you brake early into that chicane or did your brain just hit sleep mode?”
Oscar sighs dramatically. “Y/N, I love you, but shut up.”
Yuki leans around the corner. “You say that like she’s ever going to.”
“She’s not,” Max adds, sipping his smoothie. “I like her though. She yells at you more than I do.”
You wink. “Max, if we teamed up, the verbal takedowns would be unstoppable.”
Oscar groans into his hands.
Lando, at some point: “She’s so loud.”
Isack Hadjar: “She made the Ferrari PR guy cry by accident.”
Y/N, unapologetically: “I thought he was handing me a protein bar. I didn’t mean to grab his lunch.”
Charles: “I think I love her.”
Everyone: “Charles—”
Charles: “Platonically. She’s a menace. I admire that.”
YOU AND THE ROOKIES (aka Ollie + Kimi + Isack + Franco)
They orbit around you like you’re the sun and they’re deeply confused plants.
Ollie is constantly trying to match your energy and failing.
Kimi just stares at you sometimes like you’re a physics problem he hasn’t solved yet.
Isack keeps accidentally flirting with you and then combusting in embarrassment because “shit you’re Oscar’s sister.”
Franco follows you around to ask what “crikey” means or if it’s true you once knocked out a guy during a match. (It is.)
"Wait, you actually played in the Olympics?"
You nod, passing Isack a Red Bull. "Twice now. Gold in Paris."
He just stares. "That’s insane. I’m still trying to figure out how to pack my helmet correctly."
You shrug. “Different ball, same chaos.”
“Do you get nervous?” he asks.
You think about it. “Sure. But nerves mean you care. What matters is what you do with them.”
Ollie from behind a vending machine: “Is that from Remember the Titans or something?”
You chuck a bottle cap at him. “It’s from me, idiot.”
You post a TikTok of yourself doing volleyball drills with the caption: “training while McLaren fixes Oscar’s front wing for the 38th time”
The audio is “I’m just a girl :(” by No Doubt.
It hits 2 million views in a day.
YOU + CHARLES LECLERC = CHAOS DUO THE WORLD WASN’T READY FOR
Charles: “You remind me of my little sister.”
You: “Does she also destroy grown men in sports and then steal their snacks?”
Charles: “Oui.”
You: “We should form a support group.”
The two of you start a war with the Ferrari catering crew to smuggle extra snacks into the driver’s room. You name yourselves “Operation Pastry.” Carlos is horrified. Fred pretends not to see it.
Backstage at a driver press conference:
Charles (whispering): “Do you think if I fake faint, they’ll let me leave early?”
You (louder than necessary): “DO IT. I’LL CATCH YOU.”
Charles: “Non, you’ll drop me.”
You: “Exactly. Drama.”
SCENE: Australia GP - Olympic Parade Lap
They invite you to ride in the parade lap for national athletes. You wave to the crowd, wearing the gold medal, and Oscar tries to hide behind his balaclava.
You spot your brother on the grid and yell: “SMILE, OSCAR! YOU CAME FROM ME.”
He groans. Lando records it and sends it to the McLaren group chat.
Toto Wolff tells you afterward: “You’ve got good energy. Want to join Mercedes?”
You deadpan: “As long as I can bring snacks.”
Toto nods solemnly. “Non-negotiable.”
Nico Rosberg interviews you on Sky Sports.
He opens with: “So, what’s it like being the cooler Piastri?”
You grin. “Oh, I don’t know about cooler. I just talk more shit.”
Oscar yells from off-camera: “She’s not even joking!”
The Grid’s Nicknames for You:
“Chaos Wallaby” — Lando
“Spiky Volleyball Dragon” — Yuki
“Sunshine With a Megaphone” — Pierre
“The Only Piastri I’d Let Babysit My Dog” — Logan
“Paddock President” — Charles, unironically
“Don’t encourage her” — Oscar
A FEW HIGHLIGHTS:
You teach Kimi how to spike a volleyball. He accidentally dents a wall. You high-five him.
You challenge Max to a reaction time game. He barely wins. He asks for a rematch. You say “winner gets Charles’ cookies.”
You start a group chat called “Drivers Who Cry Watching Pixar Movies.” Ollie joins immediately. Esteban denies it. Charles sends four crying emojis.
You wear your medal to the Singapore GP. Yuki steals it and runs. You chase him across the paddock barefoot.
You and Daniel Ricciardo do a Vegemite taste test on TikTok. You win. Barely.
YOU + OSCAR (SIBLING EDITION)
You call him “Ice Cube.”
He calls you “Walking Headache.”
He once told Lando: “She’s the extrovert I didn’t ask for but the one the universe forced on me.”
But when you’re up at 2 a.m. crying because the press twisted your words about Olympic funding, he’s the one who shows up at your hotel with takeout and watches “Finding Nemo” with you until you fall asleep.
He’s quiet. You’re loud. You bicker constantly.
But no one gets between a Piastri and their sibling.
