Honestly, Elsa wasn't even sure why her parents even bothered to throw a going away party. She didn't really know anyone, and had very few friends; in real life anyway. She had plenty of friends online - But almost all of them lived in different states, and the rest in other countries.

But in real life? Yeah, she had no friends at all. The only real friend she'd had was her sister.

And they hadn't spoken in months.

So here she was - stuck in a room with her parents, Anna and her douchey fucking boyfriend, Hans; Her cousin, Rapunzel and her sorta-okay boyfriend Flynn; and Marcy Dunn; a girl who she was only friends with in ninth grade, because she owned a PS3. Elsa stopped being friends with her with moment she'd finally managed to save up for her own games consol, and she could stop having to hang out with the weird kid that ate her own hair.

Which she was doing right now.

Everyone was basically forced to be here. This was worse than if her parents done nothing at all.

She wished she was already in her new dorm.

She wished that she hadn't put college off for so long, just to work for her father.

She wished Anna wasn't looking at her like a wounded puppy.

Fuck everything.

"Does anyone want anything to drink?" She asked as she stood up, and picked her empty glass off the table.

There was a chorus of No's and a Scotch for her Dad.

She walked into the kitchen – grateful for the silence – and prepared her father's drink.

One more night. She told herself. She didn't try and kid herself into thinking it would be one more sleep. As much as she needed to get out of this house - as much as she needed to get away from her sister - and as happy as she was about finally making it to college; She was scared shitless.

She was going to be on her own, and she really wasn't the best at social interactions.

"Excited?" Anna asked as soon as Elsa had turned around to go back into the Den.

"For fuck sake, Anna." She scolded her sister. "Why were you just standing there like a creep?"

Anna shrugged, and stepped closer. "You didn't answer my question."

"Just take a couple of steps back." She waved her free hand at her.

"Why?" Her sister stuck out her bottom lip.

"You're being petulant. Stop it."

"Make me." Anna took another step - well and truly invading her personal space – and put her hands on the buckle of Elsa's leather belt.

The blonde spilled every ounce of Scotch out of the glass in an effort to avoid her sister touching her. "Don't." She warned.

"Why aren't you over this yet?" Anna asked; throwing her a dishcloth to wipe up the liquid on the floor. "It's been months!"

"Oh, I'm fucking sorry," She whispered angrily as she bent down and mopped up the alcohol. "I hadn't realised there was an allocated amount of time in which I had to 'get over' fucking my sister. I told you it wouldn't happen again – and it hasn't."

Anna said nothing.

Elsa didn't want to admit it to herself – but it had been hard staying away.

It wasn't just that she wanted her – she missed talking to her too. Anna had been her best friend, and now she had nothing.

"Hey Babe." Hans said as he strolled into the room. "I'm gonna get going – this party's a bust." He looked at the blonde with a smirk. "No offence, Elsa."

"None taken!" She replied cheerily. "I literally hate every single thing about you; you have absolutely no redeeming qualities - and can't wait to never see you again - you worthless, putrid, parasite of a human being. No offence!" She grinned at him, and from the corner of her eye she could see Anna's mouth drop open in shock.

"Right." He drawled as he raised his eyebrows. "Anna, talk to me when you nut-job sister leaves." And he left through the back door without so much as a kiss goodbye.

"Elsa!" Her sister snapped and stamped her foot on the ground.

"What?" She faced Anna, and asked with feigned ignorance.

"I cannot believe you just did that! He's my boyfriend for crying out loud! What the Hell is he going to think of me now?"

"Yeah, why? Why is he your boyfriend? Why have you put up with his shit for months? The guy is a money-grabbing asshole. What exactly does he have that just keeps you following him around like he's God's Gift?"

Anna laughed mirthlessly. "He's a good lay."

"I'm better." Elsa leaned into her sister's face with a snarl, and got slapped as her reward.

"Yeah." Anna hissed her agreement. "But you know what? It doesn't matter how badly he treats me – it doesn't come close to what you can do just by looking at me."

Her sister began to walk off, and she grabbed her by the arm. "What do you mean 'How badly he treats you'? Does he hurt you?"

"No, Elsa." Anna snatched her arm away from her sister's grasp. "But thanks for the concern." She said sarcastically and shook her head as she walked out of the kitchen.

Elsa rested her elbows on the breakfast bar, and put her face in her hands.

Well, that's just…Fuck.

"Elsa, Honey?" Her Mother called out. "Are you done getting Dad's drink? We want to start a game of Clue before Marcy has to leave."

One more night. One more night. That was what was getting her through this. One more night.

"Yeah!" She sighed.

It was three in the morning, and she was wide awake. She had her arms tucked under her head, and she was looking up at the constellation of stars on her ceiling, that she and Anna had painted when they were younger.

Everything except the bare essentials was packed up in boxes, and her room didn't feel like her room anymore; not that it really had for a while. She rolled over onto her side and picked up her phone from the bedside table; pulling up her photos. They were mostly of Anna; but that was the only reason she was looking.

She pinched the bridge of her nose to stop herself from crying. How could she have let things get so fucked up? She had to talk to her. It was her last night here. She was probably asleep though, and even if she wasn't – Elsa would most likely be the last person she wanted to talk to.

But she had to talk to her.

She slammed the phone down on the bed; and stood up.

There was one fairly discreet way of finding out if her sister was asleep, and she hadn't used it in years.

She tiptoed over to her built in closet, and opened it up; it looked sad without all her clothes in - she thought briefly - before stepping inside it, and closing the doors behind her. She blindly felt for the cushioned bench at the back of it and sat down –making sure to avoid the part that squeaked – and then she slowly pulled at the piece of string attached to the back. It slid open.

This particular design had not been in the blueprints of the house – it was something that she and Anna had done themselves. Their Dad would kill them - even now if he found out, and he'd probably go on about how they'd devalued the property.

But who fucking cares?

Once the panel was fully open, she could see a dim light shine through the slats in Anna's wardrobe, and she shifted closer. She could just about make out her sister's head on her pillow. She edged closer again when she heard a noise and couldn't figure out what it was.

Her breath caught when she finally got a full view.

Anna was over the covers, and her lower half completely naked; her left leg propped up – bent at the knee – while one hand pumped a dildo leisurely inside her, and the other massaged her clit with a vibrator. She didn't seem to be in any rush to orgasm.

Elsa felt her entire body blaze with desire, and her core became instantly wet.

Fuck.

Her sister's chest was exposed, and heaving; her tank top was raised up to her chin, but her hands were too occupied to tend to those perfect fleshy mounds. Her eyes were closed as she moaned quietly; and Elsa cautiously pushed Anna's closet door open.

Her sister stopped when she heard a creak, and snapped her head towards the blonde.

Elsa told herself that she should close the door, and go back to her own room as she scooted out of the wardrobe into Anna's room.

She told herself she should look away as she fully took in the sight of Anna's mostly naked, sweaty body.

She told herself she shouldn't be turned on when Anna began pushing the neon blue dildo back inside her.

Then she stopped trying to fool herself.

Her fingers twitched as she stood at the bottom of her sister's bed, and watched in complete wonder and arousal as Anna pushed the silicone toy all the way inside her; and moaned.

She almost fell to her knees at the sight.

Her skin felt like it didn't belong to her, and the noises alone were making her lose her mind.

She looked at Anna – whose eyes were locked on her – and she didn't see anger; just desire.

She climbed onto the bottom of the bed and sat on her knees between Anna's legs. She wasn't sure what to do; she didn't want to stop Anna pleasuring herself; she liked seeing the dildo go in and out – she liked that it filled Anna so completely.

She tentatively touched her sister's freckled thigh, and trailed her fingers up; and that simple act made Anna buck.

"Fuck, Elsa." Her sister sounded as if she was on the verge of tears, and she dropped the vibrator from her hand; and flung her arm up over her head.

The blonde grabbed the wild, vibrating toy that had been left unused and was aimlessly bouncing on the mattress - and she turned it off.

When she touched her sister again, it was to cover the fingers that grasped the silicone phallus, and helped her sister fuck herself. She leaned forward, and placed her hand next to Anna's hip; her head bent down resting on her stomach.

"Oh, sweet fucking -" Anna moaned, and Elsa pushed her hand harder.

She imagined what it felt like to be as full as her sister was right now, and the thought made her wetter; if that was even possible.

It had been a hundred and twenty eight days since she'd last seen Anna with her legs wide apart and ready for her to take her – and she'd thought of very little else since that day.

She wanted her; it was this base, primal need to make her sister to dig her nails into her back, and yank her hair and scream her fucking name as she came.

She took Anna's hand away from the toy inside her so that she was now fully in control of it - and she shifted herself further up her sister's body - letting her tongue dance across damp skin, until she reached her beautiful, exposed breasts. She looked into Anna's eyes; smiling - and this made the redhead whimper. She circled her tongue around a hardened nipple and then bit down gently.

"Please, Elsa." Her sister pushed her chest up against her mouth, and grabbed her hair; The blonde began to suck at the nipple, and pushed the dildo in faster, and harder, and deeper – and she listened to every sound that Anna made, and every twitch she felt beneath her – and it guided her to where she needed to be.

She wanted to be good for Anna.

When the moans became louder, she pulled away from the firm breast and smashed her lips into her sisters.

It was three in the morning. Their parents mustn't hear them - their parents mustn't find out.

But she needed Anna come underneath her. She needed her to moan into her mouth. She needed to feel the screams of pleasure reverberate through her body.

Elsa's arm felt like it was on fire, but she couldn't slow down; not until…

Anna's arms wrapped around her neck, and her legs around her waist as she spasmed – pounding her hips into her sister's hand and the toy that it held. She screamed her pleasure into Elsa's mouth and pulled her lips away so she could breathe. When it was over Elsa collapsed on top of Anna; and buried herself in her neck.

This was so very beyond wrong. Why had she allowed for it to happen again? What the fuck was it about her sister that made her lose all of her senses? This was the last time. The absolute last time.

When Anna untangled her limbs from her - without being asked – she didn't want to leave.

"Isn't this where you run away?" Her sister asked as she removed the toy from inside her. She sounded bitter; the desire had gone, and now all that was left was hurt.

"Okay." She mumbled as she rolled off her, and sat on the edge of the bed with her back to her sister. "I'm sorry."

"Sorry? Is that really the best you've got?" Anna's voice cracked at the question. "Do you even know what you're sorry for?"

"For causing you pain."

"A hundred and twenty eight days." Elsa wanted to laugh; of course Anna would count the days – just like she did. "That's how long. Four fucking months of being ignored, or talked to like a complete stranger!" A pillow hit her in the back of her head and she turned around.

Even with her anger, her sister had that post-coital glow; and Elsa's wetness began to get uncomfortable. "I'm sorry!"

"Sorry doesn't give me back those nights I cried myself to sleep! Sorry doesn't give me back those pounds I lost from not being able to eat! Sorry doesn't give me back those days I lost when I was in hospital!"

"Wait. What?"

"You didn't even come to see me! You're sorry's are fucking worthless to me!"

"When were you in the hospital?"

"Don't play stupid, Elsa." Anna clenched her teeth together and sat up against the headboard.

"I'm not." She snapped, and shifted herself closer to her sister. "When the fuck were you in the hospital? And why the fuck didn't Mom and Dad tell me?"

Anna studied her for a moment - searching her blue eyes – and then frowned. "You didn't know? Really?"

"No! Anna, no matter how screwed up my head is – I would've come to see you! Now, why were you there?"

Her sister bent her head, and pulled the blankets over her naked body. "I took some of Dad's sleeping pills about three months ago." She said quietly.

Elsa's heart sank. She hoped it wasn't her fault; but she suspected it was. "Some?" She swallowed nervously.

"All… All of them. And some vodka."

She pinched the bridge of her nose. "Where was I?"

"It was when Mom took you to see Aunt Tabitha." Elsa laughed. "Why is that funny?" Anna scowled.

"It isn't funny." She reassured her sister. "It's just that Mom sent me there because she thought I was 'too sad' And maybe a change would bring me out of myself."

"Hoo boy, did she get that wrong." Her sister joked sadly.

"I would've come home, if I'd known."

"Yeah." Anna said, and pulled her knees up to her chest.

"I've missed you."

"Yeah, well; that's your own fault."

"I know." She exhaled slowly and laid herself down on the bed.

"I'm surprised you haven't gone back to your room yet." Anna stared down at her with a raised brow.

"I can if you want me to."

"I don't."

She gave her sister a half smile. "Thanks."

"I'm sorry I slapped you."

"I deserved much worse."

Anna made an undecided noise in response. "Will you apologize to Hans?"

"Nope."

"Because you don't like him? Or because you're jealous?"

Elsa bit her lip. She had four hours left in this house; if ever there was a time to be honest, it might as well be now. "Both." She swallowed. "I don't like the idea of him touching you."

"But you've never liked him; even before we… You know."

"Anna." She said her name softly as she sat up. If she was going to be honest, she might as well go all the way. "This is not a new thing for me. Even before we… You know'd, I felt something… more than sisterly towards you. I just locked it away." Anna raised her brow and stared blankly at her for a few seconds. It was cute, but also petrifying. "Are you, okay?" She asked tentatively.

"Mmm hmm." Anna nodded. "How long exactly?"

"I don't know." Elsa shrugged. "But I realised that Summer we were at Camp and you got sick."

"I was sixteen then. That was two years ago!"

"I know."

"But two years, Elsa!"

"I'm well aware of the timeline."

"How did I not know this?"

"That's not really something I can answer."

"No." Anna replied and rested her head against the headboard.

There was silence for a long time after that. It wasn't comfortable; but it wasn't uncomfortable either. It was like static.

"Will you ever come back?" Anna asked finally. "Home, I mean."

"For holidays, I guess."

"That's it? Dad wants you to take over the business."

"Dad can fuck off."

"Oh. Okay." The redhead played with her blanket for a moment. "I'm going to miss you."

"You know there are phones, and email, and Skype and even snail mail!"

"But will you answer me? Will you reply?"

"Yes." She said putting her hand on her sister's knee. "I will."

Anna leaned over and kissed her. It was a different kind of kiss to the ones they'd shared before. It wasn't the kiss that they used to give when they were just sisters, and none of the other stuff had got in the way; and it wasn't the heated - fucking your brains out - kiss either. It was languid, and sensual, and could very easily end up in the – fucking your brains out kiss – territory.

The part of her that was logical - the part that knew what they were doing was wrong – told her she should stop this; but she didn't want to.

It was her that changed the tempo. She wanted to make the most of what little time they had left.

She eased Anna down back on the bed, and pushed the blanket away.

They had an hour and a half until their parents woke up, and she planned on pleasing her sister as many times as she could – and wanted to have her back covered in scratches before she left for college.

A/N: Okay, so yet another ElsAnna fic that was supposed to be a oneshot - and my brain went 'hahahahaha nope' I hate my brain.

Frozen has basically taken over my life, entirely. Bye bye - things I'm sure I used to do before I watched this film. Ta-ta to any concentration on things that doesn't involve this ship. So long sleep - I shall miss you the most.
