IF THIS BOTHERS YOU THEN LEAVE NOW!

(AU. No powers.)

The King and Queen of Arendelle had two daughters, each one a beautiful Princess, the apple of her parents' eyes and the pride of the kingdom. A sister.

Anna hated that word.

She never saw her older sister Elsa apart from on formal occasions. Whenever they met, Elsa wouldn't look at her, never touched her and spoke laconically, addressing her stiffly as "sister."

Whenever she knew she was going to see Elsa, Anna made sure she looked her most beautiful, wore dresses that flattered her figure and showed her freckled skin. She hoped it would convince Elsa to change, to look at her.

Anna longed for Elsa to call her by her name, to touch her skin... like she used to.

Because Anna loved her not as a sister ought to.

At first, in childhood, she understood nothing of the flame that burned within her and did not think she was doing wrong by giving Elsa kisses so often, and throwing her arms around the neck of her sister, holding her close. To them, it was simply natural affection.

Of course, now Anna knew it was considered wrong. But how could something that had felt so natural, intrinsic to her, be anything other than right? Even when their affection had started to... progress...

In truth, Anna had felt only half alive since Elsa shut her out.

But she had memories to keep her going. Memories of before it had become like this that she had dwelt upon through nearly a decade of separation.

It all started eight years ago when Anna was ten and Elsa thirteen, although Anna knew it had truly started on the day she was born, brought into the world as a companion for her sister.

The girls were sharing their bath, as they had always done. Once they finished their water fights and all the bubbles had dispersed, Anna looked down at her sister, noticing something different.

"Your chest has grown," Anna observed, curious, looking closer at the rounded contours of her sister's torso.

Elsa shifted shyly under Anna's gaze, she had hoped her sister wouldn't notice. She was growing up. She wanted to stay the same as Anna, didn't want anything to ever separate them.

"Can I touch them?" Anna asked, inquisitively.

Elsa nodded, she didn't think it would do any harm, and Anna brought her hands up to feel the soft, sensitive flesh of her newly-formed breasts.

Elsa's body felt soft and pleasant beneath her palms, and Anna compared it with her own flat, childish form. With one hand, she guided Elsa's hand to her own chest, longing to be close, to be the same as her.

The two girls sat with the steam of the bath rising around them, feeling the heat of their hands on each other's bare skin, remaining like that just for a moment.

Only a moment, but a moment can have consequences that last a lifetime.

Anna had not been able to appreciate the preciousness of that moment when it was happening, of course. Now, when she relived that brief occasion to herself in her own maturity, she awoke feelings she had never even dreamed of back then.

Memories of that touch reminded Anna that she was alive all these years later, as she tried to recreate her sister's touch with her own hands, substitute her own body for Elsa's...

From then onwards, Anna had watched Elsa blossom into womanhood. She watched Elsa's body fill out. She developed full breasts and elegant, curving hips, separated by her slender waist.

Whenever she saw her sister's naked form, Anna thought she looked as beautiful as the statues of the goddess of winter.

They sang hymns to the goddess in the temple of the Divines, hymns that called her "tower of ivory" and "house of gold." Anna had wondered how they could compare a beautiful woman to those precious materials.

But then she had thought of Elsa's white hands, the times when she placed them over Anna's eyes when they were playing. Elsa's hands were white and cold like ivory, only soft. And when Anna would kiss her neck, her sister's skin there was pale enough for her to see the veins.

And then Anna had thought of when she and Elsa ran together, chasing each other. Elsa ran ahead of her, laughing, with her fair hair streaming out behind her like gold in the sun. And the way Elsa's blonde hair would drape over her when she lay in her sister's lap, creating a world consisting entirely of the two of them...

Elsa was her "tower of ivory" and her "house of gold." Anna saw the goddesses in Elsa and worshipped her.

But she felt separated as she lingered in girlhood. Anna was skinny; no curves, no breasts, not soft and yielding like her sister.

Yet to Elsa, Anna was as lithe and beautiful as the quick-witted young goddess of the hunt. Anna was warm, so alive, untamed. Her freckles were like shivelight in the woods on summer days. And she was precious like copper and cinnamon and amber.

Months went by and Elsa continued quickly and inexorably into maturity. She grew hair. She felt the stirring of feelings she couldn't control, which wasn't helped by Anna.

Anna's curiosity got the better of her again one night when she and Elsa were in the middle of undressing, sitting naked on the bed together.

Anna stared at Elsa's reflection in the mirror beside their bed, stared at her sister's body that was now so different from her own, stared at her breasts, her hips, the patch of light golden hair between her legs...

Anna decided to ask something that had been on her mind for a while.

"Elsa, your hair..."

"What about it?" Elsa replied, gathering the loose blonde tresses over her shoulder, stroking them.

"No, your other hair..." Anna said, shifting closer towards her on the bed.

"Oh..." Elsa felt strange talking about it. "It's normal," she explained, remembering what her mother had told her. "Soon you'll have it, too." She watched Anna's eyes move from her own, to between her legs, and back again.

"What's it like?" Anna asked.

Elsa could see her younger sister's curiosity and thought she should know. Elsa had been surprised and a little scared herself when the hair had grown.

"You can look closer, touch it if you want to," she said, lying back on the bed.

Anna accepted her invitation and came closer, leaning over her sister. She put her hand out and gently stroked down the length of her sister's new patch of hair. As she brought her hand down, her longest finger brushed something warm and wet. Elsa gasped and tensed under her.

Anna withdrew her hand. "Did I hurt you?" she asked, looking up to make sure her sister was all right.

"No," Elsa replied, her eyes wide. "It felt good..."

Anna, glad that she could make Elsa feel good, leaned closer, exploring between her sister's legs. She parted her nether lips and peeked at the glistening pink flesh within, then dipped her finger into her sister's folds, feeling the heat and the dampness of her. She heard Elsa's sharp intake of breath and withdrew her fingers, returning her gaze to her sister's face.

Anna had satisfied her curiosity, and neither girl knew what to do beyond that, but, if they had been given the time, they would surely have discovered. Unfortunately, that was not meant to be.

Prompted by her own curiosity the next day, Elsa asked her mother about her body and why it had changed, why it felt good to be touched.

Her mother gave her a book, which Elsa began to read at once. It taught her about her anatomy, the function and purpose of each part. She learned about her feelings and how they were to be controlled in marriage.

Yet Elsa found the book lacking. It did not explain why she only felt heat rise to her face, and down between her thighs when she looked at the pictures of women. And it said nothing about sisters.

She returned the book to her mother and attempted to get an answer to her questions, but she was embarrassed and used the phrasing from the book.

"Can a woman only be intimate with a man?" Elsa asked her mother. She found the idea of that highly unappealing and hoped she'd answer no.

"Yes," her mother replied. "Anything else is against the laws of nature, of the Divines, of this land. Anyone who goes against those laws will be punished."

And Elsa's dreams were shattered. If she couldn't be that close to a woman, she couldn't be as close to her sister as she desired.

Anna felt like more than a sister to Elsa. Anna was her life, a part of her. Being close to Anna felt natural, even if others would think it wrong. The only person Elsa wanted to be intimate with was her own sister.

But there were laws against it. Elsa feared punishment for both herself and Anna. She feared punishment from the Divines, who knew everything, and from her parents. They did not question why Elsa suddenly isolated herself, demanding her own room immediately in an effort to prevent any law-breaking before it began.

From the age of thirteen, Elsa continued to grow, and as she grew, so did her desire for Anna.

Elsa prayed for the Divines to take away her feelings. She concluded that she and Anna were not supposed to be sisters, that the Divines must have made a mistake.

She prayed for the forbidden flame of desire to be expelled from her heart, or if the Divines could not do that, for them to take away her life. But even then Elsa had the hope that after she had perished, she would be laid out on her bed and that her sister would give her kisses as she lay, and drop her precious tears on her face...

But the Divines did not listen, so Elsa hid. She confined her passions to the nocturnal privacy of her bedchamber and concealed her love behind an icy demeanour, only seeing Anna when necessary, only calling her "sister" to remind herself of the barrier preventing her love from being anything more.

So it had been for years. And during those years, Anna grew, too. She came to learn the same things as Elsa, grew to desire her sister with the same desire.

But the rules did not bother Anna. As far as she saw it, the Divines would not have given her these feelings if she was not supposed to act on them. And she tried her best to do just that.

Anna never gave up trying to see Elsa. She waited outside her sister's locked door every day. She counted down the days to the next occasion when they would meet, hoping each time that Elsa would look at her the way she used to. Yet she never did.

But things were going to change today.

Elsa and Anna's parents died three years ago. Elsa, of course, saw this as punishment for her still un-enacted crimes and accepted her duty of taking her father's place as ruler of the land.

Now she was Queen, Elsa was forced to see Anna at the coronation party. She stood next to her sister, closer to her than she had been since their girlhood. Elsa stole a fleeting glance at her, her eyes taking in Anna's figure, her sad expression...

Elsa had an impulse to make Anna happy, to apologise for ignoring her these past eight years when she should have been there to support her, as was a sister's duty.

Elsa wanted to say "you look beautiful," but that was not something sisters were supposed to say to each other, so she just greeted Anna formally instead, never using her name, calling her "sister" to try and distract herself from the desire to uncover Anna, to touch her, to taste her, to penetrate her...

She knew that when the party was over they could go back to leading their separate lives and she could go back to keeping Anna safe from her own corruption.

Anna seemed as if she was intent on pursuing what everyone would consider normal, acceptable behaviour for a Princess. After finding that her sister was unwilling to even talk to her, Anna threw herself at the nearest man. She spoke with him, laughed with him, danced with him, pressed herself against him, frequently glancing at Elsa to look for a reaction.

Elsa watched them silently, ignoring the guests around her trying to engage the new Queen in conversation. Elsa watched them and wished him dead.

She had never even contemplated marriage for herself, not being inclined towards men, and had not considered that Anna would look for love from anyone other than her, not after all those years loyally waiting outside Elsa's door...

Elsa felt all of her desires stir and awaken within her, stronger, their need taking hold of her.

No one else had the right to be with Elsa's beautiful sister if she didn't. Anyone else would hurt her, wouldn't understand her, wouldn't have that connection between them that Elsa still felt now, that had been with her since the day Anna was born.

And nobody was there to tell Elsa what to do now, not now their parents were gone. As Queen, Elsa made the rules of this land. No one could hold her back from her sister now but the Divines... She was ready to tell Anna, to claim Anna's love for her own at last and maybe have her feelings returned...

And Elsa would rather the Divines punished her with death than suffer the torment of living with what Anna said to her after she saw her approach, her arm linked with that insufferable man's.

"Elsa, I would like your blessing of my marriage!" Anna said it with a sickeningly sweet smile at the man at her side, before looking at her sister.

In that split second of eye contact between them, Elsa felt a jolt of something stronger than love or any other emotion she had experienced, and she needed to tell Anna the truth before it destroyed her. She looked away.

"May I talk to you, please? Alone," Elsa asked.

"No," Anna replied, frustrated. "You had so many chances for that, Elsa, but now it's my turn to - "

"Fine," Elsa cut in, deciding to pull rank on Anna as her Queen and her sister. Besides, it was for Anna's own good to prevent her marrying a man she just met. "As long as I am Queen," she said, "you will never marry him, or any other man."

"What? Elsa, no! I don't understand! I can't live like this anymore!" Anna pleaded, desperately and loudly, reaching out for Elsa's hand.

Elsa felt her emotions rising as she avoided her sister's touch, felt everyone in the hall looking at them. It was too much.

"Enough!" Elsa shouted. "Everyone except my sister is to leave this room, immediately!"

It was still the afternoon and the party had barely begun, but everyone obeyed the Queen. Anna obeyed, dropping the arm of her erstwhile fiancé. There was power in Elsa's voice and Anna felt it. She wondered if now she would be able to find out the truth about Elsa's isolation, and to tell her own truth about the feelings she had not had the chance to express.

The door closed, leaving the sisters alone. As soon as it did, Anna let go of her pent-up tears and frustrations.

"What did I ever do to you but love you? Elsa, why? Why do you shut me out?"

"Because of you," Elsa began. "I have endured more hardships than you would ever believe a sister could endure. They started when we were children. We were too close. We did things that no sisters should do with each other. So, when I learned the truth of my... feelings towards you and the corruption that dwells within me, I had to lock myself away. I never look at you or touch you because when I do, I desire to be close to you. As close as when we were children, closer. I have done everything, as the Divines are my witnesses, to cure myself, to prevent us breaking the laws. I wanted to protect you, wanted to save you from me. But I can't let you go to someone else. If you have any love for me, now that you know the truth, you will respect my wishes and never marry."

It was not what Anna was expecting to hear, yet part of her always knew, deep down, that Elsa wanted her as much as she wanted Elsa.

"That man means nothing to me," Anna explained. "Everyone in the whole world means nothing to me if I can be with you again, Elsa! We're connected, we always have been. And now we're both older, and we're together again, we should be united in an even closer bond." She looked at her sister, slowly taking a step towards her.

"Laws don't apply," Anna continued. "You're Queen now, make new laws! And if you want what I want, neither laws nor fears can stop us. Under the name of sisters we can hide our secret. And as Princess, I have the freedom to meet with you in private. Even in front of others we could embrace, and kiss," Anna's eyes lingered on Elsa's lips. "No one would ever guess. We can be together again, like how we used to be, only even closer. That's the only thing I want. You alone can save me or destroy me, choose which you want to do. Because I can't live without you again, Elsa."

Elsa was moved by her words, comforted that Anna shared her thoughts, and her desires. She could not believe she had the chance to do what she had wanted for so long, and Anna was willing, too!

For the first time in forever, Elsa looked at Anna, touched Anna. And to Anna's delight, she didn't stop.

Elsa brought her eyes to Anna's face, took in her features, her freckles, her ripe mouth. She looked down, her eyes caressing her sister's curves, her freckled arms. Elsa reached out and took Anna by the hand, sighing as they touched and she felt the softness and warmth of Anna's bare skin against hers. So right...

Then together they ran, Elsa leading the way to the bedroom they had once shared. She locked the door behind them and gave in to the inevitable.

Elsa let go of her sister's hand to pull the buttons off her own high-necked, constricting gown. She peeled it off her body, stepped out of it and left it crumpled on the floor.

Anna was desperate to touch her, to confirm that her wildest fantasy was indeed coming true. She was too stunned to remove her own clothes as she beheld the vision of beauty in front of her. Elsa's unclothed body was even more heavenly than she remembered.

Elsa plucked off her crown and threw it aside, joining her discarded dress. She tossed her head and her tightly bound hair came loose, cascading over one shoulder in a thick, wavy braid. She shook it out until her light-gold tresses flowed down her naked back. Elsa felt free.

She took Anna's face in her hands and brought their lips together, fusing her mouth with Anna's, hearing her sister whimper as she lightly probed her tongue into her mouth.

Elsa broke the kiss and caught her breath, then took hold of Anna's dress by the off-the-shoulder straps, pulling it down while Anna fumbled to undo the tight bodice and discard her underwear.

When the clothes were out of the way, Elsa marvelled at how her sister had grown. Anna had a woman's body now, matching her own.

"You look beautiful," Elsa told her, and Anna could see the yearning in her eyes.

Elsa leaned in, the warm, soft flesh of their breasts pressing together, and kissed the freckles on Anna's cheeks, moving down, kissing her way to her freckled shoulders. She remained there, licking and nibbling at her sister's neck, tracing Anna's spine with her fingers for a few sweet moments.

Anna's breath came in ragged pants; she had imagined Elsa's touch on many occasions, but nothing her mind had conjured could compare with how good it really felt, and it was about to get better.

Elsa cupped Anna's breasts, feeling the nipples harden under her palms. The sensation, along with the whimper from her sister's lips, made her wet and Elsa removed her hands from Anna's firm bosom to tug off her own, now damp, underwear.

Both sisters stood naked together.

Anna moved her hands from where they had rested at Elsa's hips to touch her sister's fuller breasts, and softly squeezed the yielding flesh. She heard her sister's breathing quicken and lifted her eyes to meet Elsa's, seeing a look in them more enticing than anything she had ever dreamed.

Elsa pulled her closer, crashing their mouths together again, hungrily entwining their tongues as Anna moved her hands up to run her fingers through her sister's hair. Then Elsa moved forwards, guiding Anna until the backs of her legs met with the bed, and she was sitting astride her sister.

Anna lay back on the bed, moaning with pleasure as she felt Elsa's hands and mouth exploring her body.

Elsa trailed kisses along her sister's waist, hips and thighs, feeling the softness of her curves, until finally she settled on the coppery curls between Anna's legs. As she kissed the short, curling hair and breathed in the sweet scent of her sister, she felt Anna's hands in her own hair, guiding her, encouraging her to continue.

She parted the curls delicately with her fingers and enjoyed her first sight of the moist pink flesh of her sister's most intimate area. Elsa felt Anna tense beneath her when she brought her mouth closer, feeling her sister's heat against her lips as she kissed her cunt.

Elsa kissed it again, relishing Anna's moans of pleasure in her ears as she dipped her tongue inside, tasting the tang of her sister as she ran her tongue along the length of her slit.

Anna gasped as she felt the pressure building inside her already, but before it got too intense, she sat up, taking Elsa's face in her hands. She leaned in and kissed her sister deeply, stroking Elsa's skilful tongue with her own, tasting herself in her sister's mouth.

She stopped to catch her breath, a string of saliva and her own juices connecting them when their mouths parted, then Anna leaned down, manoeuvring herself, as her sister returned to pleasuring her, to reach that secret place between Elsa's legs. And she found it just as beautiful as she remembered.

Anna slowly brought her lips up to kiss the golden curls of her sister's sex, feeling the wetness, the heat and the scent of her.

Elsa tasted just as heavenly as she looked and Anna did her best to mirror her sister's movements, unable to stop herself thrusting up against Elsa's tongue.

Anna felt Elsa moaning into her as she buried her tongue in her folds, and Anna moaned into her in return as she began to press her own tongue against the sensitive bud near the end of her sister's slit.

Elsa could no longer control her cries thanks to Anna's ministrations, and removed her tongue from her sister's crotch, gasping for breath while she replaced it with one of her elegant fingers, sliding it, and then a second, into Anna's slick centre, stroking her insides.

Practising on herself all those years had given Elsa a good idea of what would please her sister, and she pressed her fingers inside her until Anna let out a loud, keening moan when Elsa found her pleasure point, in the same position as her own. Elsa worked at it, stroking it harder while Anna continued to coax cries from her with her tongue.

The rest of the world disappeared as the two sisters brought each other towards their ultimate pleasure, better than anything they had ever done by themselves, far beyond anything that they were aware of when they had been close as children. Their free hands found each other, and both sisters clung to the other's wrist as they reached their peak.

Elsa felt Anna's inner walls clench around her fingers and called her sister's name repeatedly as Anna pushed her over the edge with a final flick of her tongue. Anna called Elsa's name in a long, loud cry and fell back onto the bed in sheer ecstasy as her sister collapsed on top of her, feeling her body shudder as she recovered from her climax.

But neither of them were willing to end their newfound connection just yet.

Elsa climbed off her sister and let go of her hand, their palms still wet with sweat. She turned around until she was lying next to Anna. Elsa leaned over her and tenderly stroked Anna's hair from her sweat-dampened forehead.

"Anna..." she said, softly, looking into her eyes.

"Elsa..." Anna whispered in return. She laid her hand on top of Elsa's before her sister removed it.

Elsa guided her younger sister until they were both sitting, then she came closer and positioned her legs until they brought their womanhoods together, still tender and tingling from their exertions minutes ago.

Both sisters whimpered as they connected and felt the pleasure stir within them again. They fitted together perfectly, two halves of a whole, and soon found a rhythm, thrusting and grinding against each other, writhing in rapture.

Their juices mingled together and overflowed onto the bed beneath them as their cries mingled in the air.

Anna watched her sister's breasts bounce with each movement and leaned down to touch them, taking a nipple into her mouth and sucking hard, loving the way Elsa moaned in reaction.

Elsa reached out for Anna's breasts and squeezed hers in return.

This was enough to bring both of them over the edge and into the gulf of pleasure again. The sisters collapsed together and lay in each other's arms, soothed by the other's breath and heartbeat, so close.

They lay together in bliss, united and closer than they had ever been at last, until the room suddenly darkened.

Clouds obscured the sun outside, blocking out the bright daylight. Thunder rumbled overhead.

Elsa thought her worst fears had come true and she and Anna were about to face punishment for their crimes of unnatural love. But she was thankful that she had at least tasted the true pleasure of their love and been united with her sister before the end. She held Anna close and waited.

But no punishment came.

In that moment, the Divines elevated the sisters from their world, where no one would understand their love. The powers that be never made mistakes and, Anna had indeed been correct, never gave feelings unless they should be acted upon.

The suffering the sisters had experienced throughout their lives was necessary for them to see the truth of their love.

The Divines, in celebration of their True Love, the strongest power of all, ordained for Elsa and Anna's souls to be bound together for eternity, so they would live millions of different lifetimes in millions of different universes; stronger than anything, beautiful, inseparable, unstoppable.
