Chapter 10: Flames of desire

Being a princess was boring most of the time. Unlike the Queen, there weren't many royal duties that needed attending to, so Anna often found herself with more spare time on her hands than she knew what to do with. However over the years of having little to no interaction with her parents or sister, Anna took it upon herself to have as much interaction with people as possible, even if that meant taking lessons in nearly every subject known to mankind.

As she grew up Anna learned many new things, with a new teachers for every new subject. It got to the point where Anna would finish a whole topic in a week; due to the fact she wouldn't let this new person out of her sight long enough for them to disappear just like everyone else in her life.

Not many people other than the servants and her teachers knew how smart Anna really was, her playful, innocent nature causing them to believe her to be too outgoing, and full of energy to enjoy taking things slow and enjoy the simpler things in life. Such as reading a book, just like she was doing now.

Since Anna no longer needed to take lessons as she didn't need to seek attention anymore since Elsa reunited with her (also she had been taught by every teacher available and no one was left) she tended to use most of her spare time furthering her knowledge herself. After all even if she didn't have all the duties the Queen did, she still had to make sure she was ready for anything if and when the time came for her to jump into action, or even simpler than that she could always help Elsa if she found herself struggling with the work load.

So it was because of this that Anna found herself sat on the large couch in the library, her feet up on the soft material and her back rested against the side, with a book open in her lap as she tried to stay concentrated on the words printed there. Anna had been staring at the book for the past half an hour but her mind liked to wander, and recently it always wandered to the same subject matter. Elsa.

'What am I supposed to do, I want this but can I still do this?' Anna thought to herself as she was reminded once again of what happened to her when a jolt of pain shot through her shoulder. She was trying hard to suppress memories of the details, but no matter how hard she tried they always shone through stronger than ever, his eerie smile, hot, disgusting breath on her face, and rough hands grabbing whatever they could touch.

Anna shook her head and pushed the book off her lap, it fell to the floor with a thud as she pulled her legs up to her chest and wrapped her arms around them. 'No stop, he can't hurt me anymore, he's locked away and will be for a long time, Elsa will protect me' She rattled on in her head as she rocked back and forth ever so slightly with her head shaking at the same time. She knew this was a lie, he would continue to haunt her every waking moment for years to come, and it wouldn't stop there, he would visit her at night causing her to wake up in a fit of flailing limbs and angry tears, as her mind thought back to how she could have stopped him and should have stopped him right from the start.

Silent tears trailed down her scrunched up face, 'But I couldn't stop him, there was nothing I could do!'

Of course there was, you could have fought, kicking and screaming, you could have pushed him, hit him, BURNT HIM!

"NO!" Anna shouted into the empty room, her hands in fists and angry tears dripping into her lap, her voice echoed around the large room and when she heard the forcefulness of it, it made her want to continue speaking her reasoning. "There was nothing I could do, what's done is done, there is no point thinking about how things should have been, it's time to put that in the past and try to move on with my life, otherwise I won't be able to do anything ever again without him looming over my shoulders, and the only person I want looming over my shoulders is Elsa!" Her voice had gotten progressively louder until she was basically shouting the words, Elsa's name now echoed around the library.

Anna felt like a strange weight had been lifted from her, now that she had admitted to herself that there was nothing she could have done to alter the events Anna felt better, almost calmer than she did not moments ago. This was good; it was a step in the right direction, she thought as she took a deep breath before picking up the book from the floor and placing it on table near the couch.

The Princess slumped back into the comfy material and let her limbs go slack, she felt exhausted and completely drained of energy, but was else did she expect after she had stopped warring with herself. Her voice had only just stopped echoing around the room, the last syllable of 'Elsa' slowly dying out until the library was once again, silent.

'Elsa' Anna thought to herself with a smile, a lot had happened between the two and in such a short space of time, but she was just glad that she no longer had to hide her feelings and that Elsa actually returned them. A blush spread across her cheeks as her mind became more primal and thoughts changed from Elsa to Elsa's body, and to the few times they had come close to expressing their love for each other.

Anna huffed her frustration, 'If kai hadn't interrupted us this wouldn't be so hard!' she thought back to when Elsa kissed her for the second time telling her she didn't care what others thought so long as they were happy and together. Things had started to get pretty heated and she was sure that if no one had interrupted them, they would have expressed their love through clumsy kisses and inexperienced hands with laughter following when they didn't know what to do.

However that hadn't happened, and now Anna was stuck with still no experience and finding herself terrified of messing up or not being good enough for Elsa. She wasn't too concerned with worrying if she would burn Elsa again, Anna was fairly certain the whole incident was caused by her intoxicated state and lack of control over her powers didn't help in the situation. Anna also now had the added problem of Elsa not wanting to scare her with contact due to what happened, but it was Elsa's touch that helped her the most. She groaned and let her head fall back against the cushion, 'what am I going to do?!'

Before she could even start to think of an answer, her stomach answered for her, growling in hunger. Anna's hand went to her stomach and waited for it to settle before standing up, thinking on an empty stomach was never a good idea, so she decided it would be best to get something to eat before continuing this brain storm.

She quickly exited the room and headed for the kitchens, shutting the library door behind her. Anna knew things would work out in the end but she didn't know how she would get from this point in time to that point in time, and it was this that made her worry. She wondered if Elsa was having any better luck than she was.

The Queen had wasted no time in finding the general and captain; she demanded an emergency meeting with them and a few dignitaries she felt needed to know about the threat, she needed people to help her prepare but she didn't want everyone going into a panic.

To say they were shocked with the news was an understatement. At first they didn't believe her, but as she explained the situation and what had happened with Eldric they started putting the pieces together and agreed they should prepare for a possible attack. All other duties aside, Elsa worked with the others to get her soldiers ready for battle. Ensuring they had all the necessary equipment, swords, shields, spears, armour anything that would protect her kingdom.

They discussed a battle plan focused around the element of surprise, after all Northwind didn't know that Arendelle knew of their upcoming arrival so they planned to keep it that way. With surprise on their side they could ambush Northwind's army before they even manage to make it to the castle gates, ensuring they had the advantage for if fighting did break out, and they could protect the castle for a longer time if the fighting dragged on.

Happy with the progress she had made in the short space of time, Elsa left the men to discuss how they were going to structure the soldiers for the ambush. The next plan of action was to get supplies stored and ready, so Elsa set out for the kitchens, they would need to get as much food and water stored away as possible just in case they needed to hold out in the castle.

On her way she ran into Kai and a thought crossed her mind. He had been present during the meeting and she had asked him to keep the information to himself so as not to panic others, however she realised they didn't have time for that. She stopped him and asked, "Kai, I need you to gather up the other servants and guards, go to the lower town and bring them up to the upper town, set them up in the castle if need be, just make sure they are as close to the castle as possible."

He looked shocked, as if he too had her realisation that they probably didn't have much time until they had an army at their doorstep, nodding he replied, "Yes, of course your majesty, but what do I say to convince them to leave there homes?"

Deciding the time for secrets was behind them she stated, "Tell them exactly what's happening, that there may be a war and an army is on its way right now, make an announcement if you need to" she went to keep walking but another thought crossed her mind, she turned back to him, "Once you have the people moving from the lower town, get the guards and any volunteer's to help barricade up the lower town, make sure every alley way, every small gap is closed off, leave only the main street open, I'll join them to help once I have things sorted here."

Kai just nodded, "Yes your majesty" before going on his way, there was a time and a place to question her motives, and now wasn't one of them.

As she got closer to the kitchens she noticed that lots of the staff had started to hurry out of the castle, word must have gotten round that they were needed elsewhere. However when she got to the kitchens all staff were present and going about their usual jobs, good that would make this job a whole lot easier and quicker. As she looked around at the smiling faces that greeted her, she failed to spot the fiery hair in the background rummaging around for something quick to snack on.

Elsa coughed making her presence known, a few of the staff looked her way, "If I can have your attention, please stop what you are doing" she waited until everyone's attention was on her, yet again she didn't see the crouched strawberry blonde at the back of the room, probably because her head was in a cupboard, "I'm here to announce that the peace treaty between Northwind and Arendelle has been broken, as we have reason to believe that Northwind's army is on its way here to attack us as we speak."

A hushed whisper went around the room as everyone took in the information, Elsa continued, "So in preparation we need to get all available food that will stay fresh and all water stored and ready in various parts of the castle, for later distributions and for in case a part of the castle falls or is taken by the enemy" she waited for them to register the information, it was a lot to take in all at once, "If that's understood then we need to get started right away" before she even finished her sentence people jumped into action, packaging various items of food, several higher qualified staff members organising where certain things would be taken and stored.

Anna's head shot up when she heard the words army and Northwind in the same sentence, the chocolate pastry falling from her mouth all but forgotten as she looked in the direction she had heard her sisters voice. She saw Elsa stood watching over the action taking place, voicing her opinions on where she thought they should store the supplies and then take her leave, her blonde hair just making it out of the door before it closed behind her.

Needing answers Anna rushed after Elsa, her hunger forgotten too concerned with all this talk of an attack. "Elsa, Elsa wait!" She shouted to the older girl as she tried to catch up with her.

Surprised to hear Anna's voice, Elsa turned around to see her sister running after her, she asked, "Anna, what are you doing here? It doesn't matter we don't have time for this, we can talk as we walk" she started walking again when Anna caught up with her but at a slower pace so the younger girl had chance to catch her breath.

Surprised at her sisters comment Anna opened and closed her mouth a few times before finding the words she wanted to say, "Elsa what's going on? What's this about an army?"

There seemed to be more people in the halls now, rushing back and forth with various items or messages, it was starting to get crowded and Elsa couldn't think straight. "We are about to be attacked by Northwind's army, I don't know when but it could be at any moment so we need to be prepared" she answered as they turned the corner and continued down the hall, there were even more people here 'great just what I needed'.

"How can you be so sure about this?!" Anna questioned she just couldn't believe what she was hearing, sure Eldric had turned out to be a deceptive monster but surely the rest of Northwind wanted to uphold the agreement between the kingdoms. As she thought this there was a small part of her mind telling her it made sense but she refused to believe that they could be going to war, that sort of thing just didn't happen to Arendelle.

"Anna listen to yourself, even you doubt what you're saying, doesn't it make sense that they would want to attack us after trying to kill me! That was there plan all along, Eldric more or less told me so himself" Elsa exclaimed as they manoeuvred around the crowd.

Anna grabbed at Elsa hand and pulled slightly getting her to stop walking before she said, "Well I want to help then, anyway I can, I could fight, we could fight together…"

Elsa interrupted her, "No Anna, you will do no such thing! I don't want you getting hurt, you will go nowhere near the fighting, do not reveal your powers to anyone I thought we agreed to this?"

"Yes but Elsa, now is as good a time as any for everyone to know, I could help everyone, I could save countless lives!" Anna didn't understand why Elsa was so against the idea of her helping; she was more than capable now that she could burn things to a crisp, but seeing the tears welling up in Elsa's eyes and her hands in tight fists she started to worry that she had maybe said something wrong.

Elsa had blocked everyone else out at this point, she was focused solely on the wonderful, selfless woman before her, "But at the price of your own! I don't want to lose you again Anna, I can't watch you get hurt, I can't watch you die! Not again!" she spluttered out, emotion thick in her voice.

Anna's expression softened and she moved closer to Elsa, cupping her cheek and wiping the tears away with her thumb, she spoke softly, "Oh Elsa, I'm not going anywhere any time soon ok, you don't have to worry nothing's going to happen to me, if you're not there to protect me then someone else probably will be like Kristoff, and I can always take care of myself now." Elsa nodded but couldn't bring herself to speak, Anna smiled. "I love you Elsa, I will always be here for you when you need me."

What she expected Elsa to do was say she loved her back, but instead Anna was surprised to find herself being pushed back to the wall, and into one of the many rooms along that hall. She looked around and saw that they were in one of the guest rooms; she looked back to Elsa when she heard the door shut and lock with a click.

"Elsa what…" she was interrupted by Elsa embracing her in a passionate kiss, that caught her off guard and caused her to simply stand there in shock, wasn't she upset just seconds ago?

Elsa broke the kiss and whispered into Anna's ear, "I need you now Anna, right now." She felt Anna shiver at her words.

"I'm right here for you."

That was all Elsa needed to hear.

Wasting no time she latched her mouth onto the soft skin exposed to her, trailing open mouthed kisses along Anna's neck, eliciting soft moans from the younger woman. Elsa felt hands gripping at her hair keeping her in place and she smirked against the smooth skin, this wouldn't do at all they had hardly even started yet.

She broke away from the hold Anna had on her, and she was met with a confused look before she pushed Anna back onto the bed behind her, causing a small squeak to escape the Princess when she fell back.

Anna lifted her head to look at Elsa and playfully shout at her for pushing her, but the suggestive look Elsa was giving her caused all coherent thought to be lost from her mind. All she could do was watch on in awe as her eyes drunk up the picture of sophisticated grace that was her sister, change into one of a sexy seductress as she stepped out of her royal outfit and ran her hands through her hair letting it fall down her back in a sprawl of curls.

"Like what you see Anna?" Elsa asked with a giggle, Anna had been watching her closely her eyes never blinking for a second. Anna just nodded, not sure she trusted herself to be able to speak properly. Elsa tilted her head and smirked, "Well I don't think this is quite fair do you? I haven't got a lick of clothes on, but you; well you are still fully dressed dear sister."

Anna found herself liking this flirtatious side of Elsa and hoped she would be seeing more of her in the future, smirking in return she said, "Well we should fix that then shouldn't we, why don't you come over here and help me out of this dress" she curled her finger in a come here action to further entice Elsa over, not that she needed to.

"I'd be glad too" She replied before making her way over to the bed with a swing in her hips that caused Anna to moan in anticipation. Elsa straddled the younger woman and didn't hesitate in stealing another kiss while her hands started on removing the cloth from Anna's body, slowly but surely they managed to remove the dress and all other garments that were previously in the way, the cloth was thrown across the room without thought as the two sisters returned to admiring the others beauty.

Elsa let her eyes run over her sister's body, just as she thought, Anna was stunning. Freckles were littered all over her chest which just made her look all the more adorable as she blushed up at Elsa. The blonde moved her hands up and down Anna's sides caressing the soft skin in a relaxing manner trying to calm down the nervous girl, "You're beautiful Anna" she whispered before kissing her way down Anna's chest.

"E-Elsa" Anna gasped when her older sister's mouth closed around one of her erect nipples, her hand fondling the other breast. The sound of her name being moaned just spurred her on and Elsa continued her actions, her teeth lightly scraping over the skin causing the girl to groan in pleasure. She switched her actions giving attention to the other breast, her tongue flicking lightly before swirling around the nipple, Anna was writhing under the treatment one hand bunching up the covers of the bed in her fist and the other placed firmly behind Elsa's head keeping her in place.

Anna had been waiting for this moment for so long, whether it was because they had been interrupted and the tension between them had been building, or because Elsa was very skilled with her tongue, she didn't know (Anna suspected both) but what she did know was that the pleasure she was feeling was so much more than she could have ever imagined. Her whole body hummed with energy from the point of contact with Elsa's touch, and shoots of pleasure ran down her body right to her core. If Elsa didn't hurry this up she wouldn't be able to last much longer.

The Princess roughly pulled Elsa's head up away from her breasts and crashed their lips together, before stating huskily, "Elsa no more playing, you said you needed me, now take me, I'm yours."

Elsa didn't need to be told twice. She distracted Anna by claiming her lips once more, her tongue asking for entrance which was quickly granted, while at the same time her right hand trailed down the smooth skin of Anna's stomach to the soft curls below. Without much other warning, Elsa plunged her fingers into the growing wetness she found and rubbed at Anna's bundle of nerves with her thumb.

"Fuck! Elsa!" Anna gripped at the older woman's shoulders, her nails biting harshly into the cool skin.

The way Anna's face was scrunched up in pleasure, biting at her lip, made Elsa's core throb. She could feel herself getting wetter every time Anna moaned; it was music to her ears.

Elsa quickly found a rhythm of pleasuring the girl, her fingers pumping further into Anna, hitting her sweet spot every time causing her walls to clench at the blondes fingers. Anna's moaning had become more needy and frantic, her body shaking with the build-up of pleasure; she was very close to the edge.

The blonde leaned in close to Anna's ear, she whispered, "Anna, let it go" before nibbling on her ear and quickening the rate at which she rubbed the hard nub.

Anna was plunged over the edge.

Her moans filled the small room and her body shook from her orgasm, had either of them not been so distracted they probably would have wondered if people walking past could hear them. As she came down from her high, Anna's muscle spasms calmed until she finally collapsed back against the bed, releasing Elsa's shoulders from her previous death grip.

Elsa smiled down at her sister, admiring the peaceful, calm expression currently on her face, it was short lived however when Anna shot up and changed their positions, pinning the older woman underneath her.

"I have to admit dear sister, that was positively delightful, however it would be unfair of me not to share this pleasurable experience with you, so now it's your turn to lay back, relax and enjoy" Anna smirked as she gave Elsa a quick kiss on the lips before pushing her down, and starting to leave a trail of kisses down her body.

The blonde found herself gasping and moaning as she tried to find something to grasp hold of, but found nothing but empty space and bed covers, as Anna paid close attention to her breasts. Just like Elsa had done for her, Anna took one of the hardened nipples into her mouth, flicking her tongue and gently biting down, her hand making headway with the other breast pinching the hard nub.

"Anna, oh Anna!"

Elsa's moans encouraged Anna to continue and gave her a confidence boost; clearly she must be doing something right for her sister to be making such beautiful sounds. She continued to kiss her way down Elsa's stomach, caressing the smooth skin with her finger tips causing Elsa to shiver in anticipation. Anna stopped just above the blonde curls and looked to Elsa for permission, who looking down at her baby sister between her legs blushed heavily before giving a curt nod of allowance.

The strawberry blonde caressed the cool skin of the creamy thighs in front of her, before ever so slowly pushing them further apart to allow her better access to her sister's core. Anna could see from here that Elsa was dripping wet, just the thought of it turned her on immensely, but now wasn't about her, it was about Elsa.

Anna tentatively dragged her tongue over Elsa's hard nub, causing the Queen to throw her head back and let out a long throaty moan. With encouragement from Elsa, Anna continued to attack the blondes throbbing core, her tongue dipping into her wetness, plunging deeply and lapping up all that Elsa gave her.

"Holy- Fuck me!" Elsa groaned as a particularly violent spasm coursed through her body, causing her to jerk upwards forcing Anna deeper into Elsa still.

Anna laughed, sending vibrations through Elsa's core and bundle of nerves causing a fresh wave of pleasure and all new sounds to escape the blonde, "That's what I'm doing Elsa if you hadn't noticed."

Elsa forced her head up to look down at Anna, the image of her sister with her juices dripping off her face just served to turn her on even more, she smirked, "Oh I definitely notic- Hnng!" she threw her head back when Anna continued her assault, sucking hard on Elsa's nub.

The rate at which Elsa's legs were jerking it wouldn't be long until she climaxed. Anna pinned down Elsa's torso with one arm and with her other, she replaced her tongue in Elsa's core with her fingers and started to thrust them deep inside, hitting her sweet spot that caused Elsa to mewl, grabbing Anna's head and keeping it in place as she licked and sucked at her clit. Anna smirked, she knew Elsa was close and it would only take a bit to push her over the edge and she knew exactly what to do.

Anna curled her fingers deep inside Elsa catching that sweet spot again, at the same time she sucked hard on Elsa's nub and bit down slightly. The blonde's walls clenched down hard on her fingers and Elsa let her pleasure be known as she rode out her orgasm, only when Elsa had stopped jerking did Anna remove her fingers and clean herself up, sucking her fingers clean and wiping her face.

Elsa still had her eyes closed, her face a picture of pure bliss, when Anna curled up behind her, slipping her arms around her older sister. The Princess placed a soft kiss in Elsa's hair, "Wow, Elsa that was amazing and you are so beautiful."

Turning around in Anna's arms to look at her directly, Elsa kissed her before replying, "It was wasn't it, but you are the beautiful one Anna."

Anna smiled and rested her forehead against Elsa's, "but you're beautifuller! I love you Elsa."

"I love you too Anna" Elsa whispered, Anna had fallen asleep exhausted from their love making. The blonde pulled Anna close and made herself comfy, coming to the conclusion that it would be acceptable for them both to be missing for a few hours, after all Kai had everything under control he didn't need her there to execute the instructions she had already given. Everything would be fine for a few hours while the two sisters enjoyed a nice nap together, then afterwards they could discuss properly about matters concerning the potential war, but for now Elsa allowed herself to succumb to unconsciousness traveling to the land of dreams.
