A/N: Wrote this a while back for the ficathon held at elsannafervor on tumblr, and finally got around to uploading it here. I meant for this to be mostly a comedic oneshot, hence why it's marked as complete. Hope you all enjoy!

(716): I just sent a bad sext to my sister. There's not even a way to damage control this, is there?

— TFLN

It had been a dare. A dare.

Nothing more than a stupid, impulsive, little dare.

And like an idiot, she took it—hook, line and sinker.

Anna stared at her phone, cheeks puffed and arms crossed over her chest. Her foot wiggled back and forth as she contemplated her next move. She'd been sitting in the middle of her room on the floor for the past ten minutes, heat steadily creeping from her ear tips all the way down her neck.

"You can back out anytime you know."

Anna shot a glare at her laptop screen, where Kristoff was watching her through FaceTime with a worried expression.

"I mean, c'mon Anna, Hans doesn't have to know you didn't do it. He let you pick who you could send the text to."

Anna huffed and jiggled her foot. "He'd just ask to look at my phone for proof Kristoff. That's why we agreed that you would be the one to get the text because—"

"Because anyone else would be ew."

"Seriously ew!" Anna shuddered and made a gagging motion. "How do people do this?! Isn't dating supposed to be romantic? With like candles and fancy dinners?"

Kristoff laughed and Anna's nerves eased a bit. "I think most people send stuff like this to people they trust, not take 'Drywalls are more arousing than you,' as some kind of dare."

Anna bristled. "It was a dare! And that's not the way it went either!" She began to chew on her thumb as she recalled Hans's bet earlier that day.

I can totally do one text. I mean, how hard can it be? Just say a sexy line and then presto! I'll show that jerk Hans that Anna Anderson doesn't back down from a fight. Not only will those fifty bucks be mine, but Prince "Charming" will have to live through senior year that I was—

"Isn't Elsa coming home soon?"

Anna looked up. "What?"

Kristoff rolled his eyes. "Elsa. The sister you don't shut up about."

Anna glared at him. "Hey! We had a few rough patches last year, I'm allowed to babble about my sister—"

"The one who's probably going to wonder why her baby sister has several history searches about, 'How to send a sext.'"

She paused. A little, tiny, itty-bitty prickle of worry squirmed in her chest. Ever since her parents' separation, Elsa had been the more…restrained of the two. As stoic and stiff as her father. Prudent, just like Daddy Dearest. Neither her nor Anna's father had visited much, having moved halfway across the country.

It hurt a lot the first couple of years. She cried. In bed, in the shower. At school. She refused to talk to either of her parents for months. Then one night she begged to see Elsa. That's when her parents had decided to patch things up a bit. Elsa had even decided to attend university here in Arendelle.

Anna swallowed the lump in her throat. "Well, it's not like Elsa and I share a room. And it's onmy computer, she'd never even—"

The front door creaked open and then shut.

"I'm home!"

The sweet, melodic voice sent a shiver as delightful as it was worrying. Footsteps thudded up the stairs and Anna rushed to shut her laptop. The rational side of her brain told her she was being very irrational, but screw that. She wasn't about to let her conservative older sister see a side of her that was neither smart nor charming.

Anna had just about shut her laptop when a knock sounded on her door.

"C-come in!"

Elsa poked her head in, blue eyes lighting up when they landed on her. "Hey Champ, are you busy?"

Anna coughed and tucked a strand of hair behind her ear. "Uh, just finishing up some homework. Why?"

"Oh." Elsa gave a tentative smile. "Well I was wondering if we could have a movie night."

Anna perked up, a bright grin stretching across her cheeks. "Sure! I'll get us some popcorn—"

"But first finish your homework," Elsa said. Anna pouted and she laughed. "Let me know when you're done."

Anna melted and gave a little wave as her sister left. She was staring at her door for a few minutes before Kristoff spoke up.

"So the bet's off?"

And just like that, Anna felt her annoyance spike up again. "Oh no." She snatched up her cell phone off the floor and opened her contact list. Kristoff was in the "Best Friends" category, right below Elsa. Her tummy fluttered and a dopey grin spread across her cheeks. Elsa was waiting for her. Thoughts of cuddling up next to her sister as they watched Disney or Pixar flooded her mind as she typed absentmindedly.

"Hey sexy, my bed's been so lonely on these cold nights. Why not be my personal teddy bear…" she mumbled, then paused and tilted her head towards the ceiling. "Do I send like, a pose too?"

Kristoff snorted. "Wow that's unsexy. And no, no pose. That's too weird. I see you every day. If you did that, I wouldn't be able to eat lunch tomorrow."

Anna huffed, a light blush blooming on her cheeks. "Well, fine. I'll be enjoying my lunch tomorrow with Elsa. She promised we'd have a girls' night out."

"Ahuh."

Anna pouted at the disinterested answer. She hit send while her brain jumped to wondering if Elsa would be open to letting her drive. She'd just gotten her license and wanted to show off her skills. It would be great!

"Did you get it?" Anna asked, glancing at her laptop after half a minute.

Kristoff was frowning at his phone, one eyebrow quirked. "Uh, no, not yet. You sent it right?"

Anna blinked and straightened. "Yeah, of course I did." She glanced at her cell. "Man, I swear your phone is slower than—"

A stone fell into the pit of her stomach. The color drained from her face. Anna felt her breath shorten.

Oh no. Oh no, no, no.

"Anna?"

She stood up shakily from her chair, blue-green eyes staring in horror at the recipient's name. A series of garbled sounds escaped her throat.

"Okay, now that is seriously unsexy Anna," Kristoff said. He frowned when she didn't respond, still staring at her phone and making useless noises. "Anna, what is it? What's wrong?"

Anna made one last strangled noise before dropping her phone and jerking her door open. She rushed down the hallway faster than the time Kristoff had told her a chocolatier shop had opened two blocks from school.

The door slammed against the wall as she barged in and screamed, "Don't read that!"

Startled blue eyes flashed in her vision. Anna barely had time to take in Elsa's shocked look before she had thrown herself at her sister. The world tumbled around her, white ceiling mixing with blue drapes and sheets. She smelled mint and expensive perfume.

And tasted cherry on her tongue.

Anna pulled back, wide blue-green eyes taking in her sister's even wider expression. In the back of her mind, she wondered when Elsa had started wearing her favorite lipgloss.

Anna stumbled off her sister, a blush spreading down her neck. "I, uh—"

Elsa slowly rose off her bed, eyes darting from her to where her phone lay on the floor. Anna glanced at it. It was open to her number. Anna let out a squeak before bolting back to her room.

She slammed her door shut and leaned against it, heart thundering like a stampede.

On her laptop, Kristoff frowned worriedly. "Uh, Anna?"

Anna let out a strained laugh, though it sounded more like a dying animal.

"I screwed up."
