A/N: So I wrote this a while ago and I've been on and off editing it forever. It's just a one-shot. But if you guys like it and want a sequel, I could give it a try. :)

Warning: Contains incest. Don't like then don't read.

Elsa rolled over beneath the heavy covers, the swishing of the slippery cloth bringing her out of the shallow sleep she had been floating through. Her right arm was numb from being squished under the weight of her side. It began to tingle uncontrollably as blood rushed back into it. Elsa winced at the odd sensation as it pulsed through the limb. She waited for it to pass before moving again.

The room was mostly dark, except for the silver moonlight that pooled in through the large triangle window of her Arendelle castle bedroom. The light seemed to sway as clouds rolled past the reflective sphere in the navy sky, surrounded by millions of little stars that sparkled about it. Elsa loved the moonlight, and seeing it spread out over the wood of her floor and casting strange shadows on the already darkened walls made the Queen all the more aware of her awake-ness. She let out a large sigh of defeat.

The sound of movement and a soft grumble from across the room caused Elsa's heart to stop momentarily. Then the memories of the day flooded back.

Anna had insisted that they share a room again, like they had as kids. At first she'd objected like any proper adult would. There was no way she'd let Anna have her way, especially when it came to something so childish. But Elsa then discovered how much she couldn't say no to her younger sister's pleading eyes and pouting face, especially after all they'd been through. Elsa felt she owed her way more than just smiles and words of affirmation. So she gave in, for now. After all, Anna was just trying to come up with as many ways as possible to make up for the time they'd lost together. And Elsa wanted nothing more than to be close to Anna, it was all she'd ever wanted. But two grown women sharing a room? She silently hoped that that sort of knowledge amongst the staff wouldn't make it past the castle gates.

Elsa sat straight up, loose hair spilling around her face and down her back as she looked across the room. Through the dim light she could see the familiar (yet unfamiliar) bed frame that housed her sister's sleeping form.

After Elsa had finally given into her younger sister's demands, the two of them had argued over who'd move into who's room.

"Pink is just not my colour anymore, Anna," Elsa said as she and her sister paced around the study. Elsa's hands rested on her hips and Anna's arms were crossed over her chest. "I honestly don't know how I tolerated it as a child. I much prefer blue. My blue."

"But blue is so… so…" Anna threw her arms up in the air in search of the right words. "So dreary and melancholic."

"Which suits me," Elsa sighed, tilting her gaze toward the floor.

"Hey! I never said that. Oh, Elsa…" Anna said, approaching her platinum blonde sister with outstretched hands, placing them on the Queen's lean, chilled arms. She gave her older sister one of her signature warm smiles, teal eyes glimmering up toward her own icy blue one's. Elsa let out a breath she hadn't realized she was holding and began to unwind under her sister's touch.

"I really can't stand pink," Elsa insisted.

"All right. Your room it is. It won't take much to move my stuff, anyway."

Anna continued to smile at her sister, as if every bit of what they were feeling was as pure as a new born lamb.

The Queen rose out of her bed and walked across the room to gaze upon her sleeping sister. She no longer felt sleepy. There were just too many thoughts swirling in her head, like snowflakes in a blizzard, unable to reach the ground.

Her sister's body was tangled between the white and pink sheets, her limbs sprawled out in every direction and her chest slowly rising and falling as she breathed through rosy, slightly parted lips. Her hair though, it really had a mind of its own. It looked like she'd been caught in a wind storm. The thought made Elsa giggle as she carefully sat down onto the mess of sheets, doing her best not to disturb the red-head's apparent deep sleep.

With a gentle sweep of her pale fingers, the Queen stroked some of the crazy strands of hair away from Anna's closed eyelids. She smiled at the view.

The tips of her fingers then lingered on the sharp curve of her sister's jaw longer than she had intended. Before she knew it the memory of Anna, as she stood in the midst of the frozen fjord with her entire being turned to ice, had wormed its way to the surface of her thoughts. It was the moment when Elsa had held Anna's icy cheeks in her shaking palms, unable to understand; comprehend; believe what had taken place. Little snow flurries started to twirl in the air around the blonde and her face cringed from the tang of dread that spread throughout her chest, forcing her to pull away from Anna; away from the bed. She leaned up against the dark window pane, letting the shining light and despair envelope her whole being.

Elsa didn't know how much time had passed. It could've been hours or just a few minutes. But the world seemed to have become darker, much darker. She felt her consciousness falling backwards within herself. Tears threatened to drop from her eyes. What if Anna had stayed frozen forever? What if she hadn't froze in time and Hans's sword had struck her, slicing her hand right off. What if…

The hunched Queen stiffened as a shiver moved through her spine. Something was sliding around both sides of her waist, locking her into a tight hold, which lurched her vision back to the moonlight. She felt a flat stomach and a pair of small breasts press against her back. Elsa's breathing hitched at the onslaught of sensations that the single embrace created within her. Her arms tensed on top of Anna's. She moved her hands to cover her sister's that rested against her middle, clasped together.

"Anna, you should be asleep," the emotional reck-of-a-Queen managed to force past her lips.

Her sister squeezed tighter.

"No fair, Elsa. If you get to be awake then I get to as well." Anna whined, childishly.

Elsa couldn't help but smile as she turned around in Anna's firm hold, her icy blue nightgown twisting around her slender figure.

She looked into her sister's eyes, and for a moment it felt as if they'd gone back in time; that they were innocent children, filled to the brim with wonder and excitement. A true happiness. Until it had all changed. Again, Elsa felt the despair moving in, and she let her head dip down, her forehead unintentionally pressing against the top of the red-head's own. She let out a soft whimper of defeat. Snowflakes began to drift in and around them.

Anna's whole face frowned.

"You've got to fight this Elsa. I'm here. I'm alive. There's nothing for you to feel sad about."

"But I am sad, Anna. I can't…" Elsa choked on the lump of tears in her throat, trying as best she could to conceal them.

Then suddenly Anna let her go and backed away. The older sister almost fell forward, causing her to slightly flail in search of her balance.

"Look at me, Elsa. What do you see?"

The Queen looked up. She smiled. Then she let out a light chuckle; bringing the tips of her fingers to her lips as she did so. Her sister's hair was a complete crown of mess and her pink, wrinkled nightgown hung loosely around her body. Her armed were covered in a crisscrossed pattern of lines created by the sheets that had been pressed into her skin. She looked nothing like how a proper princess should look.

Anna's serious expression dropped as she realized why Elsa was suddenly so amused. She tugged at the fly-a-ways, groaning in frustration when they wouldn't stay down. This made Elsa giggle all the more. Leaning up against the window frame, Elsa said, "I see the Princess of Arendelle, who's unable to control her crowning glory, among other things," with a wry smile.

Anna's speckled cheeks became visibly red with embarrassment. She turned and dramatically sulked back to her bed, flopping face first onto it with a loud 'poof'. Elsa walked over to her sister's bedside, taking a seat and placing her hand on her sister's right shoulder blade.

"Cheer up, at least you got me to smile," the Queen said encouragingly, noticing that the snowy air was no where to be seen.

"But what I was trying to get at was that I'm all right. I'm healthy and in one piece and I'm here. There's nothing for you to be sad about…" Anna's words slowly came to a halt as she looked up at her older sister. A new smile had spread across her pale cheeks. Elsa was right, she did seem content now.

But she was no where near happy. Something still troubled her and the audible sigh that followed showed as much.

"What is it now?" Anna asked as she pulled herself up to sit next to her sister.

Elsa didn't really know what to tell her. When she looked at Anna the feeling was there. Her heart almost seemed to ache. It didn't make sense. She should be happier than ever now that her and Anna were together. But the puzzled expression that covered the young Queen's face wasn't enough to convince Anna of her predicament.

"Please don't shut me out, you can tell me anything. We're sisters after all," Anna almost laughed as the words left her mouth. She really had no idea how normal sisters were supposed to interact with each other. Elsa hadn't been around to help answer those abandoned questions. Well, until now.

But for the Queen, the word sisters seemed to echo in her mind. Why was that word so haunting? Why did it seem to torture her so?

Anna sat, watching in silence until she couldn't wait any longer.

"Elsa," she moaned, lengthening the last syllable.

"Anna, I-I don't know."

"I think you do know but you just don't want to tell me."

"No! Of course… That's not-" but then Elsa stopped. Did she really have no clue? She felt that she might know. But at the same time she couldn't come up with words to describe it, even to herself. It was as if her own mind wanted to hide the truth from her.

"If you won't spill it willingly, then I'll make you."

"What? That's absurd."

But then Elsa was suddenly beside herself in worry. Anna was looking at her almost… hungrily; a mischievous smile tugging at the corners of her mouth.

"You've got 10 seconds: 10, 9," Anna started to count down, raising her hands up in front of her, like claws.

"Wait, what happens at zero…?" Elsa stammered, attempting to slide away from Anna. Her back was met with the bed poll and she couldn't go any further.

"8, 7, 6," Anna continued to count, glaring toward Elsa, like a predator studying its prey. Elsa's cheeks turned bright red and the temperature of the air around them began to drop. She couldn't handle any of what was talking place before her.

"I can't tell you! I don't know how!" Elsa shouted pleadingly.

"5, 4, 3,"

Elsa shot up from the bed in an attempt to flee, but Anna's quick reflexes proved to be too much for her and she found herself instead pinned to the very bed she'd hoped to escape from. Her sister was upon her, licking her lips in a seemingly seductive manner.

"2, 1,"

It was in that moment that Elsa felt warmth for the first time. It billowed up from within her like a volcano preparing to erupt.

As the word zero left Anna's upwardly curled lips, antsy fingers began to attack Elsa's sides mercilessly. Elsa's body lurched in shock, eyes slamming shut as she let out a squeal of surprise. She hadn't been tickled by her younger sister since they were little, before the fateful accident that had changed the courses of their young lives.

"Anna, stop!" Elsa begged between attempts at trying to conceal her laughter. She found it was almost impossible to control her body's movements as her sister's hands dug into her sides and ribs, and then suddenly slipping into the pits of her arms. She found herself shrieking.

"Oh gods! No no no!"

Anna was grinning like a crazy person, her hairstyle only adding to the effect.

"So, are you ready to tell me what's going on, oh regal and composed Queen of Arendelle?"

Elsa shook her head from right to left, deciding to play along with her sister's little game. A plan of retaliation was (somehow) forming amongst her jumbled thoughts.

Elsa's hands, which had initially been trying to push Anna off of her (to no avail) decided to change tactics, diving straight for Anna's own armpits.

Anna squealed and instinctively drew backward, trying to get away. And within seconds, the tables had turned; Elsa now mounting Anna, tickling her armpits and sides without mercy.

Anna laughed and giggled between shouting words of apology, pleading for the sweet torture to cease.

"Please! Hahaha! Elsa, I'm sorry!"

Anna's breathing was getting heavy, her cheeks becoming as red as strawberries. Elsa knew it was time to stop, but a part of her (and she had no idea where it had come from) didn't want to stop touching the girl beneath her. She didn't even notice when her hands had stopped tickling all together, instead beginning to caress her sister's weary body ever so soft and gradually.

Elsa's hands moved over top of the little mounds of Anna's chest, fires igniting in both their cores. Elsa couldn't believe how amazing it felt. The warmth. The heat. She wanted more. She wanted it to consume her; to never be extinguished.

But Anna snapped back into reality. The small flames that danced within her were making her feel uncomfortable, and for good reason. She stared up at her sister, who she knew was too drunk on adrenaline (and possible arousal) to realize exactly what she was doing. The platinum haired girl continued to knead slowly at her breasts, causing the red-head to moan beyond her control. Anna knew this was getting out of hand. She had to bring her sister back.

"Elsa, this isn't right. You've got to stop."

But just as she finished saying it, Elsa set her forearms down just above Anna's head, leaned in, and then kissed her. Lips cold as ice.

And It was in no way a sisterly peck of any sort. Anna could tell. It was passionate and clumsy, and Elsa wasn't letting up. Anna didn't know what to do. She was pinned down and afraid of hurting her sister. Her sister who was kissing her.

This is all your stupid fault, Anna. You started it, she thought to herself.

Then it dawned on her.

This was what Elsa couldn't tell me.

Anna pushed her sister back with as much force as she could muster. To her surprise, Elsa was so out of it that she didn't even fight back. As Anna managed to slide out from underneath her older sister, she watched the other's face begin to flush an even deeper shade of red than her own. Slowly, Elsa's thoughts came into focus.

"Anna," she breathed.

The red-head gulped. Elsa's eyes widened.

"Oh gods! Oh no. Anna! I'm so sorry!"

The not-so-regal looking Queen started to move away as if she was being pulled back by a chain looped around her neck. Her face had twisted into an expression of plain fear.

"Elsa, it's okay. You just… you got a little lost there for a moment. But you're back now and I'm fine."

"No no no, I've done it again. I hurt you, I-" the memories of the moments before flooded back into Elsa's mind. "What have I done?"

Elsa's face was beat red. She curled herself up into a sitting ball near the far corner of the bed, eyes wide.

"Elsa, is that really how you feel about me?" Anna asked, finding the question harder to ask then she thought it would be. Elsa's throat went dry.

"I don't… I don't know. I've never once felt heat of any sort before, and then you…" but Elsa just couldn't finish. She was beside herself in shame.

"Then it's totally my fault, I shouldn't have pushed you to that point." The words felt strange to say, but she said them anyway as she placed a hand on her sister's shaking shoulder. But Elsa ripped away from her, standing from the bed.

I should've never given into Anna's childish demands, Elsa thought. I should've never let her get so close to me. I should've never opened the gates. I should've never been born.

I'm disgusting.

"Elsa, don't-"

"Anna, go back to sleep." The words rang sharper than knives.

Elsa collapsed into the shadows of her neatly kept bed and she cried in silence until the sun had chased away the night.

A/N: Update: Due to the seemingly good attention this fic has generated and the demand for more to the story, I've begun writing a sequel. That in no way means it will ever be finished, but it is in the works as of now. Thanks for your reviews, favourites and follows; I appreciate it. :)
