Run for it and try to borrow Anna's clothes

Elsa stared at the crowd, her eyes wide. She was barely listening to the queries now, too concerned with the insistent trickle of water running down the inside of her cleavage, the cool droplets melting under her crossed arms. Despite her best attempts to keep the dress cold she couldn't counter the Sun and the heat of her skin.

She squirmed. Much more of this and she'd be naked in front of Arendelle. Again. Queen Elsa swallowed, pressing her legs together tightly and silently praying for her skirt at least to stay together. She risked a peek down, hastily using her powers again to steady it. The pattern drooped almost immediately.

Oh god; her cheeks were burning, and apparently the more flustered she got, the more her skin heated up, the quicker her clothes melted. A squeal escaped her lips, the undignified sound drawing more surprised looks from the crowd, and making her flush all the redder. She could feel the remains of her dress dripping over her arms, feel her forearms press against her bare tits.

Ice-cool water ran in droplets down her body, pooling between her legs. As one travelled the length of her pussy she immediately squealed again, hastily shifting on the spot.

"Th-that's enough for today!" Elsa said.

"Your majesty?" the herald said, turning.

She stared incredulously at him. How must she look?

She could only imagine. Her blue dress drooping and melting away, barely an echo of what had been over her shoulders, leaving her as good as topless if not for her wet, frantically crossed arms. Her skirt clinging to her legs as a gap opened up in it, letting the people see higher and higher up their Queen's legs until-

She shuffled in her throne again, hyperaware of the feeling of a moist cushion against her bare skin. She focused, trying vainly to recreate the skirt. If anything she only felt more water.

"W-we'll continue this later!" Elsa said.

Too quickly she stood up, too embarrassed to worry about the panic in her voice. She shrieked as fragments of her dress fell to the floor like snowflakes, too fragile with how little was holding them together.

No, there was no point in wasting time making her dress again if it was just going to melt. She kept both her arms crossed over her boobs, two adjacent Vs made with her elbows in an effort to cover up. Her pussy was left covered with only water and the sheer hope that something of her dress remained; she refused to look down and disillusion herself.

Breathlessly, Elsa ran to the side of the room, trying not to think about how the air felt against the cool water that covered her behind. She whimpered, rattling the door with one hand before eventually barging through the door and slamming it shut behind her.

Panting, Elsa slumped against the door, pressing her back to it and pinning it shut with both arms and hoping no one had come through, and hoping even more that there had been something stopping all of Arendelle from seeing her royal ass.

Suddenly a servant walked out into the corridor. Elsa yelped; the servant-woman dropped the sheets she was carrying as she beheld her naked Queen.

"G-go away!" Elsa shrieked.

Any other time she'd have felt guilty about being rude. After a moment she quickly hunched forwards, leaning and moving her arms from the door to try vainly to cover up, one arm again in a V over her chest, her other hand in front of her pussy; the ice-cool water trickling past it still made her shiver.

Eyes wide, the woman quickly backed away into the room she'd just come from.

Oh god, she couldn't just stay out in the corridors. She needed to get somewhere, somewhere with real clothes. She could go to her room and make a dress, but it would just melt as soon as she got outside. She needed something...

Anna! They were sisters, similar sizes, and as a Princess Anna's clothes were the kind of thing Elsa too was expected to wear. Her people had just seen her stark naked, the last thing Elsa needed was for them to see their queen huddled together in whatever sheets she could find.

Though even that would be better than this.

Taking a deep breath, Elsa started running. She moved as quickly as she could through the hallways off her castle, leaving damp footprints in her wake, never lingering for any longer than she had to as she passed doorway after doorway.

By the time she'd made it to Anna's room, even what little hints of blue had remained of her dress, little more than transparent snowflakes pressed against her skin, were gone. Clad in nothing but the melted remains, Elsa knocked frantically on her sister's locked door.

"Anna!" Elsa yelped. "Anna!"

She glanced from side to side, blonde braid whipping back and forth as she made sure no more servants were passing by to see her like this.

After a moment she heard a muffled voice from the far side of the door.

"Ah! I'm awake! I'm awake!" Anna said, audibly sleepy.

"Anna, let me in!" Elsa shrieked, pounding on the door still.

It was a long few seconds before the drowsy Anna at last, at last, opened the door; it took her a good second to open her eyes wide enough to realise her sister was naked in the hallway, and by that time Elsa had hurried inside, panting from relief at being out of public view.

"E-Elsa?" Anna said, blinking. "Why are you..."

"Later!" Elsa said, blushing. "I just need to borrow your clothes."
