Ed notes: Okay, this one is... I don't even know. It was prompted by a morning radio segment with a caller's story about their most embarrassing moment, and ended with Luka's brain ceasing to function. This is fun, silly, pure fluff, and it is Lukanette. I hope you enjoy it.

Locked Out

A Miraculous Ladybug fanfictioin

By Mintaka14

When Luka answered the frantic knocking, he opened the door and found himself staring into the bluest pair of eyes he'd ever seen above bare legs that went all the way up to the oversized tshirt the girl was wearing. Her blue-black hair made an adorably dishevelled mess, and she was hugging a largish parcel.

"You're not Juleka," the girl blurted out, and, thanks to those blue eyes, he found himself having to think about that for a moment.

"No, I'm not," Luka said eventually, and he was fairly sure that that was the correct answer. "I'm her brother. Can I help you with anything?"

Please, let me help you with something!

"I needed to borrow her underwear," the girl said on a note of rising desperation. Any blood left in his brain after seeing her bare legs fled south and abandoned him. "And maybe her balcony."

"Guh- " he said eloquently, and stepped back, gesturing haphazardly to invite her inside.

Words were proving difficult. Coordinated movement was even harder, but he was fairly sure he shouldn't leave a damsel in distress (and out of underwear, a voice in his head reminded him unhelpfully) standing in the hallway. He followed her into the living room, trying very very hard to not stare at the glorious curve of her butt under that tshirt, or think about how far up those bare legs went. He squeezed his eyes shut.

"I just got up," she was saying, "and I hadn't got dressed yet, because, you know, just got up, and I wasn't expecting the delivery this early, but I had to sign for it and it was only for a moment, except I had the balcony door open, and then the breeze slammed my front door shut and I was locked outside. Without underpants."

She turned, and stumbled to a stop as she suddenly seemed to realise what she'd just said to him. She looked up at him, and a pink blush dusted her cheeks.

"And I can't climb back up to my apartment without underpants." She gave him an adorable smile. "Is there any chance I could borrow some?"

It didn't even occur to him, in that moment, that leaving a complete stranger alone in his sister's living room to potentially rob them blind was unwise, and if it had, he would have cheerfully helped her pack up Juleka's entire apartment if it meant that she'd smile at him again. Instead, he almost ran to his sister's bedroom and grabbed the first pair of underpants that he found in Juleka's chest of drawers. He handed them wordlessly to the gorgeous girl in the living room.

It wasn't until she turned a brilliant scarlet with the scrap of lace and silk in her hands that he realised that he was still staring like a creep and spun around. He tried to block them out, but the rustling noises behind him as she put the pants on were going to fuel his hottest dreams for a very, very long time.

"So," he croaked. "How do you know Juleka?"

Please, dear God, don't let her be one of Juleka's girlfriends …

"I'm a designer, and she got a modelling gig with the atelier that I work for a few years ago. We started chatting, and then it turned out that we lived in the same building, so… You can turn around now," she said, and Luka turned to face her. "She has a spare set of my keys for when I do stuff like this."

This girl turned up half-naked on a regular basis? Luka was halfway through making vague plans to move in with his sister before the rest of what she was saying registered.

"But I can't see them in the bowl where she usually keeps them."

Luka followed the line of her gaze, and indeed, the bowl by the door was empty. Maybe she could move in with them instead if she was locked out forever? He was happy to share.

"So if you don't mind, I'll just use the balcony."

Wha-?

She reclaimed the package from the couch where she'd put it, and padded on bare feet towards the balcony door. She paused, and glanced back at him with a shy smile.

"It was really nice to meet you. Thanks for your help, and tell Juleka that I'll return her underwear once I've washed them."

The strangled noise that he made might have passed for a response. He really wasn't sure of anything, including his own name, and he watched as she climbed up onto the balcony railing with her parcel tucked under one arm. She swung herself out over the edge and, with a heartstopping twist, caught the next balcony over one-handed.

She flipped the parcel up onto the balcony above that, hauling herself effortlessly after it, and holy crap if that wasn't the hottest thing he'd ever seen. Her bare legs flashed out of view, and Luka dropped bonelessly into the couch.

When Juleka finally got home, he was still sitting there, one hand pressed over his mouth, and his sister kicked his leg out of the way as she passed.

"What's gotten into you, dumbass?" she asked. She dropped the bags of shopping on the counter and turned back to her brother. She waved a hand in front of his face.

"I met one of your neighbours," he said in a daze, and Juleka's eyebrows rose. "Dark hair, said she knows you from work, climbs like a ninja, legs like you wouldn't believe, and god, those blue eyes…"

Juleka's brows rose further. "Marinette was here? Wait, climbs like a ninja?"

"Yeah," Luka sighed happily. He probably should ask Marinette out to dinner at least once before he proposed. He was pretty sure that was the right thing to do. He probably should introduce himself to her first.

"What did she want?"

"Your underwear."

"What?
