Stark Secret

Parings → Peter Parker x Stark! Reader

Warnings → Fluff, Chaos, Post-Endgame AU (Tony survived because I said so)

Summary → You and Peter have been secretly dating behind Tony's back... until he finds Peter half naked in your bed.

｡･:*:･ﾟ★｡･:*:･ﾟ☆ ｡･:*:･ﾟ★

It started with one rule. Just one.

"No dating until you're thirty, especially not that Parker kid."
Your dad, Tony Stark, had said it in his usual charismatic snark, like he was joking-but oh, he meant it. Meant it with every bone in his genius billionaire body.

Too bad you fell for Peter Parker before you could stop yourself.

Now you were knee-deep in a secret relationship, supported by almost every Avenger, Aunt May, your friends, even your mom, Pepper. Literally everyone knew except Iron Dad himself.

And this morning? This was the day everything went to hell.

The Night Before

Peter had swung in through your balcony window at 11:47 PM sharp, hoodie half-zipped, hair tousled from the wind.

"Hey, sweetheart," he whispered, grinning, sneakers already half-off.

"You're late," you said, arms crossed, but your smile betrayed you. He dropped his backpack, wrapped his arms around you, and pressed a soft kiss to your forehead.

"Had to report to your dad and avoid the Stark security protocol. I think F.R.I.D.A.Y. suspects me."

"She totally knows. But she likes me, so you're safe."

You fell asleep cuddled under your galaxy-themed blanket, legs tangled. You in a tank top and shorts. Peter in his boxers. It was pure, innocent, domestic bliss. The kind of moment you dreamed of since sophomore year.

Unfortunately, Peter forgot to leave at 6 AM.

8:26 AM - Stark Tower, Your Room

Your door swung open without warning.

"Rise and shine, princess! Time to-"

Tony Stark froze. His sunglasses slid down his nose. He stared at Peter, who was still asleep, arm wrapped around you like a damn Hallmark card.

Peter stirred. "Mmm... five more minutes, babe..."

Tony's voice boomed like thunder from the ninth circle of Hell.

"WHAT THE HELL IS GOING ON?!"

Peter's eyes snapped open.

"AH!" he shrieked, bolting upright and nearly falling off the bed.

"PARKER! WHAT ARE YOU DOING IN MY DAUGHTER'S BED?!"

You sat up, groggy, hair a mess. "Dad! It's not-"

"NOT WHAT IT LOOKS LIKE?!" he yelled, arms flailing, pointing wildly at Peter's half-naked state. "HE'S IN BOXERS. YOU'RE-YOU'RE IN-WHERE ARE YOUR CLOTHES?!"

Peter tried to speak but came out sounding like a broken microwave. "Mr. Stark! I-I swear! We didn't do anything! I love her, but I mean-not that way, not last night-I mean I love her that way but not that way-oh god-this is how I die-"

"YOU'RE DAMN RIGHT THIS IS HOW YOU DIE!"

"Tony!" Pepper stormed in, pulling on her robe. "Why are you yelling like you're being stabbed?!"

"Because I AM being stabbed. IN THE HEART. OUR LITTLE GIRL IS-"

"Oh my god." Pepper took one look and then turned to Tony. "Out. Now. Come on. You knew this would happen someday."

Tony blinked. "Not when she's nineteen! Not with Peter! I was rooting for Harry Styles at least!"

"Out!"

Tony, fuming like a dragon, let himself be dragged out, mumbling, "Should've installed lasers in her bedroom walls..."

Peter sat on your bed like a ghost.

His face had gone pale. "That's it. He's gonna send me to space. Without a suit. I'm toast. I'm space toast."

You cupped his cheeks gently. "Peter."

"I love you. Please remember that. Bury me somewhere nice. Maybe on the roof, I liked the view from there."

You couldn't help but laugh. "You're not gonna die. I mean, you might get yelled at again, but Mom's got him under control."

"I saw my life flash before my eyes. I was a baby goat for some reason."

You pulled him into a hug. "We'll tell him the truth. The whole truth. And maybe... wait until he's eaten breakfast first?"

Peter nodded slowly. "Yeah. Yeah, good call. No bad news on an empty stomach. Basic survival."

Meanwhile, downstairs...

Clint was already placing bets with Sam on how long Peter would last.

Nat sipped her coffee. "Ten bucks says Tony builds a 'No Peter' drone."

Bucky leaned over to Wanda. "I kinda wanna watch the next round."

Wanda just smiled, already texting you, "Good luck. Try not to let him vaporize Peter. We like him."
