Cosplay Exhibitionism Club - Chapter 1: The First Flash

Lucy adjusted the blue tie of her Marin Kitagawa cosplay, her heart pounding as she walked over the crowded convention floor. The chaos of an average cosplay convention surrounded her—booths overflowing with merch, cosplayers striking poses for photos, and far too many people for the tight space. She throws the hair of her blonde wig over her shoulders,while the pleated skirt of her schoolgirl outfit covered her little secret: A pair of black panties with "Fuck Me" printed in bold white letters on the front.

She’d spent weeks preparing herself up for this moment. It wasn’t her first time cosplaying, that's not what made her so nervous today. She has been sewing costumes and attending cons for years, but today there was something different. There was always this secret desire inside of her, the thrill of exhibitionism. A fantasy she’d never dared to try – until now. Her goal was simple but just thinking of it makes her shiver: Flash her panties to someone at the convention. Just one person. A quick lift of her skirt, a moment of exposure, and then she’d vanish into the crowd with her secret safe but her desire fulfilled.

But as she walked down the halls with her plan in her head, a problem occurs: She couldn’t muster the courage to do it. Every time she spotted a potential target - a confident guy in a hero cape, a group of giggling cosplayers, even a lone photographer - she froze. Her face flushed, her legs trembled, and she walked away, muttering excuses to herself. What if they judge me? What if they take a picture? What if they tell someone? The convention hall felt like a maze of missed opportunities, and with each passing hour, she gave up on her plans more and more.

After too many failed attempts, Lucy found herself in a quieter corner of the convention center, away from the main stage and vendor booths. Her feet ached, and her confidence was fading away. She leaned against a wall, playing with her phone and sighed. Maybe this was a stupid idea. Maybe she wasn’t the type of girl for this.

Then she saw her.

A girl sat alone on the floor in the corner, her back against the wall, knees drawn up. She wore a stunning cosplay—a gothic Lolita dress with black lace and a red rose choker, her dark hair tied with ribbons. She was scrolling on her phone, seemingly oblivious to the convention’s chaos. Lucy’s breath caught. Another girl would be easier, she thought. Less intimidating than a guy, less likely to leer or make it weird. A girl might understand, might even laugh it off. Lucy’s heart raced as the idea took root. This was her only chance left.

Lucy swallows her nerves on edge, then she smoothed her skirt and walked toward the girl. Her steps were slow, deliberate, each one a battle against the voice screaming at her to turn back. When she reached the girl, she stopped directly in front of her, standing close enough that her shadow fell over the Lolita’s phone. The girl looked up, her eyes curious but not unfriendly.
Lucy’s face burned. Her hands hovered at the hem of her skirt. Do it. Just do it. With a shaky breath, she gripped the seam of her skirt and lifted it, revealing the panties underneath. The words "Fuck Me" stood out against the black cotton, impossible to miss. Lucy held the pose for a single, endless second, her face turning red as she stared straight ahead, avoiding the girl’s gaze. Then, as panic overpowered the thrill, she dropped the skirt and turned around ready to run, her heart hammering.

But a hand grabbed her wrist.

Lucy froze, her stomach twisting. It’s over. She’s going to yell, or laugh, or report me. Her mind spiraled with worst-case scenarios as she slowly turned back, bracing for judgment. But when she met the girl’s eyes, she saw something else entirely - amusement, maybe even admiration.
“Hold on,” the girl said, her voice soft but teasing. She looked around to ensure no one was watching while still holding Lucy’s wrist. Then, with a mischievous smile, she lifted her own voluminous skirt, revealing a pair of black lace panties. Lucy didn’t expect such an reaction at all, she just gasped and stood there unable to say anything.
The girl dropped her skirt and grinned. “I’m Mia” she said, releasing Lucy’s wrist. “Nice choice, by the way. Bold.”

Lucy blinked, her brain struggling to catch up. “I… uh… I’m Lucy” she stammered. “You… you’re not mad?”

“Mad?” Mia laughed, tucking a strand of hair behind her ear. “Girl, I’ve been doing this for years. You’re new at this, huh?”

Lucy nodded, her cheeks still burning in red color. “I just… wanted to try it. I didn’t think anyone would… you know, get it.”

“Oh, I get it,” Mia said, her eyes sparkling in joy. “There’s nothing like the rush of showing off, especially in cosplay. The contrast of being someone else for a day, but exposing the most YOU you can be. ”

Mia tugged Lucy down to sit beside her on the floor and Lucy didn’t resist, her curiosity outweighing her nerves. They leaned against the wall, and started talking. It didn’t take long for Lucy to realize Mia was like her—a cosplayer with a secret love for the thrill of exhibitionism. Mia confessed she’d flashed her lace panties a few times at cons, but always subtly, always to someone she trusted. “It’s like a game,” she said. “You pick your moment, your person, and you make their day.”

Lucy laughed, the tension in her chest easing. “I was so scared you’d think I was a freak.”
“Nah,” Mia said, nudging her shoulder and giggling. “You’re my kind of freak.”
Then Mia’s expression turned conspiratorial. “We should team up,” she said, her grin infectious. “I act all bold, but I’ve never gone further than what you did today. I’m always too nervous to escalate.”

Lucy raised an eyebrow. “Escalate?”

“Yeah,” Mia said, leaning closer. “Next convention, we pick a guy—someone cute, maybe a little shy—and we flash him together. Double the fun, half the nerves. We’ll plan it out, make it perfect. Costumes, timing, the whole deal. What do you say?”
Lucy’s eyes widened, but the idea sent a thrill through her. Flashing a guy, with Mia by her side, felt less daunting, more like an adventure. She imagined them in matching costumes, giggling as they executed their plan, the rush of adrenaline binding them closer. “You think we could pull it off?” she asked.

“Of course” Mia said. “We’ll choose the perfect target, maybe someone who’ll blush but appreciate the moment. Or maybe a nerdy cosplayer who’s too shy to make the first move. We’ll make his con unforgettable.”

Lucy hesitated for a second, then smiled. “I’m in.”

Mia couldn‘t hide her excitement and jumped up from the floor. “Yes! Okay, we’ve got work to do. We need costumes that scream confidence but leave room for the reveal. Maybe something with short skirts or tear-away panels. And we need a code word, in case one of us chickens out.”

“Code word?” Lucy asked, with a curious voice.

“Yeah, like… “Wig slipped” Mia said. “Say it, and we abort mission, no questions asked.”

“Wig slipped” Lucy repeated, nodding. “Got it.”

Mia handed Lucy her phone, her contacts app opened. „Let's exchange these for today. Or is that too revealing for you“. Lucy enters her number, laughing. “If I chicken out now, how should I be able to flash a guy then“.
They walked out together, weaving through the thinning crowd. Lucy felt lighter, like she’d unlocked a part of herself she’d kept hidden for too long. Mia, with her fearless energy, was the perfect partner in crime.

As Lucy headed home that night, she couldn’t stop smiling. She’d come to the convention hoping for one fleeting moment of bravery. Instead, she’d found a friend, a plan, and the spark of something much bigger. The next convention couldn’t come soon enough.
