"Cold, cold, cold," Anna gasped and pranced across the tiled floor and nearly dove into the shower in her haste to warm up. She gasped with relief as the hot water hit her skin. Elsa might say the cold never bothered her, but for Anna there was nothing worse than deep winter in the castle. All the braziers in the world couldn't keep the chill out of the air.

She was just beginning to warm up when the door to the bathing room opened, letting in an icy blast of air that made the shower curtains billow.

"Anna?"

"Elsa? Shut the d-d-door," she demanded with chattering teeth.

The door clicked shut. "I didn't know you were in here," the queen said, sounding apologetic.

Anna rubbed at her arms, trying to recapture the warmth she had felt so briefly. She suddenly became aware that she was stark naked with her sister in the room. She smiled though her chattering teeth.

"I need to shower," Elsa said.

Anna poked her head out of the curtain. Elsa looked perfect, as always – a big bonus of making your clothes out of ice is they kept clean. "You can wait," she said coolly. "I'm trying to warm up."

Elsa rolled her eyes. "I just met with the local tanners. Do you know what they use for making hide?"

Anna sniffed, then nearly gagged. "I can guess," she said. She drew her head back in. "You can join me, then. I'm not getting out until my bones have thawed."

Elsa pulled aside the curtain, her dress melting off of her into the air in the same moment – a skill Anna found both incredibly useful and enviable. Anna yelped and drew back from the cold.

"Big baby," Elsa said, smiling and stepping into the water.

It was Elsa's turn to yelp. "Too hot!" she cried and quickly grabbed at the tap. The water instantly became frigid.

"Elsa!" Anna grabbed the hot water handle.

"You're going to burn us!" Elsa said. She turned the hot off again. Before Anna could turn it back, Elsa waved a hand and a small blast of ice shot from her hand.

"No fair!" Anna whined, staring at the ice covered knob. Elsa smirked, a smile both too sexy and too frustrating for words. She grabbed the soap bar and began to scrub at her ivory skin.

Anna stood there, shivering for a long moment. God, Elsa was hot. If only the water matched, she might be able to enjoy herself.

A few more moments of watching Elsa wash and she lost patience. She grabbed grabbed at the bubble bath and, before Elsa could said 'Wait -what?" had upended it over her sister's head. Elsa's hair was quickly enveloped in the lavender bubbles of Oaken's finest.

"Unfreeze the knob, bubble-head," Anna said in her best threatening voice.

Elsa scooped her hand through her hair, pulling a large ball of suds out.

"Don't you d-" Anna's cry was stopped when the bubbles smacked her face. Elsa laughed as she sputtered, the taste of soap coating her tongue. She wiped the bubbles away with the back of her hand. "Oh. It is on."

She lunged at her sister, hands at the ready. Elsa was ticklish – more ticklish than Anna would ever have believed before the time when Elsa had accused her of hogging the covers. The queen was entirely at her mercy as her fingers danced over her bare skin, finding all her weak points.

"Anna -" Elsa shrieked and giggled uncontrollably. Anna did not stop.

"Unfreeze it!" The cold wasn't even bothering Anna anymore. Her face was flushed with the sheer fun and excitement. Elsa tried to tickle her back, but couldn't stop laughing enough to do so.

She was going to win.

"Truce! Truce!" Elsa gasped finally, lifting her hands above her head in surrender. Anna relented, a pleased smile playing across her lips. Elsa's hair was free of the bubbles now, and it clung to her shoulders and breasts as she took a moment to catch her breath.

After a moment she waved a hand, releasing the ice and turned off the water. "We're both clean," she declared. She took a step forward and wrapped her arms around Anna. "Let's go to my room. I'll warm you up."
