A/N: I do thoroughly apologize for the late chapter, I'll try to have chapter 16 out in a more timely manner. Until then, enjoy!

"You know," Elsa said as she finished up her first slice of pizza, "you might just be the best cook I've ever met."

Anna giggled, covering her mouth with her hand to avoid flossing her partially chewed meal. Her face was a little red and she squirmed a little, which Elsa found endearing. They were on the couch in their now standard position, with the elder sitting up and her beloved sister splayed across the cushions, using her sister's thigh as a pillow.

Elsa was getting anything but calm in this position. No matter how many times they sat like that, she was about as cool as the inside of a steam engine. Which is exactly what the room began to feel like as Anna wiggled on her leg.

Anna finished chewing, continuing to ignore a movie they put in a little while ago, and in a hyperbolic tone said "I think I make a better arsonist than cook!" She swung her arms to emphasize her point, which, Elsa was unable to help but notice, pulled up her shirt to just above her belly button. A detail that the so called 'arsonist' didn't fix. Elsa was giggling until she noticed.

Not that Elsa was complaining, because she wasn't. She was enjoying every millisecond that she was able to glue her eyes to her sister's pale, smooth abdomen. It was like looking into a bright light that she couldn't bring herself to turn away from, unfearing of the threat of blindness from such a sight as her mouth went dry and her heart felt like it was dying. She felt a magical whirl of heat fizzle in her own core and sink impatiently. She wanted to kiss Anna's stomach. Realizing that she had literally been staring at her sister's belly button for a few seconds and that a response was still needed, Elsa blinked and tried to re frame her mind. "I- I'm sure that chicken would agree with you," she managed to quip.

With a suppressed shriek of laughter, Anna bit her lip and playfully slapped Elsa on the arm as she countered "watch it, or next time I'll make you eat that chicken."

Elsa leaned in for another slice, inadvertently brushing her breasts against her sister. The contact scared the life out of her and cooked her like a lobster in a pot, even giving her that nice, pure red color. She almost choked and frantically tried to bring herself back upright.

Anna squeaked with what sounded like it might have been a giggle, but Elsa was too busy to be sure. In her haste to remove her boobs from her sister's face, she managed to hurdle a wad of pizza sauce into the air. Her eyes widened as she tried and failed to catch the red glob.

It landed on Anna's exposed stomach.

Elsa looked at it, then to her sister's cherry red face, a fantasy of leaning in and licking it off flickering into her mind like a strobe light. She felt a hot flash and tremor in her heart and had to forcibly keep herself entrenched in reality, like a ship anchoring in a storm. "whoops, s-sorry," she said, grabbing for a napkin. She was about to dab it off, but was frozen by another burning image. One of caressing Anna's stomach, watching prickling goosebumps spread over her sister's skin. Elsa's heart was pounding.

"Well," Freckles said, still in a teasing voice. "You can't just leave it there."

"R-right, y-yeah, sorry." Elsa reached down with the napkin, face and core burning as she continued to use her imagination.

Anna markedly tensed as her sister wiped down her stomach, and Elsa was honed in on how close she was to rubbing Anna's nether region. All I'd have to do is unbutton her shorts... Elsa felt a flare ignite between her knees, she sucked air. All that was left was a tiny bit of sauce by the seam of Anna's shorts. Elsa couldn't help herself, she tried for discretion as she wiped her pinky across satin smooth skin. It sent a tingle from her fingers all the way down her back, giving her goose skin and hardening her nipples.

She just hoped Anna didn't notice anything.

Elsa dared a look at teal eyes. Her sibling's face was red. There was a moment of silence so tense that it threatened to shatter Elsa's secret box of sensual desires and spill her sexual tension all over, turning the air husky and heavy, like Elsa's breaths had become moments before.

Thankfully, Anna was apparently unaware of the platinum blonde's antics. She coyly said "thank you, my maid," with a devilish grin.

The comment managed to wiggle a chuckle out of Elsa, breaking any threatening tension circumscribing her. She lightly slapped Annas wrist. "You watch yourself now."

Raising an eyebrow, the younger girl called Elsa out. "Oh yeah? What are you gonna do?"

Grinning wryly, Elsa leaned her pizza over Anna's stomach as a threat.

Anna called her bluff. "If you drop that, you'd better eat it," she warned. Her face was flushed and Elsa could have sworn there was some sort of undertone in the sentence. One that made her heart flutter, or sputter like a dying engine. She almost choked.

And she thought about it. She thought about actually letting her slice roll off of her finger and crash into Anna's perfectly formed stomach, but the heat that the idea of eating the slice afterwards brought her inches from fainting. In defeat, she dropped her hands.

Anna donned a smug smile. "Pizza was a good idea."

Elsa smiled into red cheeks. "Yes it was, Freckles."

With a contented hum, the younger sibling rolled and adjusted her body so that her shoulders were flush against Elsa's stomach and her head was still using the same thigh as a pillow. Elsa, of course, was thrilled by such a large area of contact to a point that watching the movie was difficult. She very demurely rested one hand on Anna's side while the other began giving her a scalp massage. When Anna purred like a cuddly cat, Elsa's heart rate quickened and she reveled in it. On top of this, Elsa was hyper-aware of the brief moments when Anna's shoulder would brush or press against her boob while the younger girl adjusted. It was just a light touch and it drove Elsa wild, she felt almost feral as her carnal desires shocked her and pooled like lava between her knees.

She was going to have to do something about that soon. But for now, she'd enjoy Anna's company and the gentle massages they were providing for one another.

But she didn't have much time to do that, either. The door swung open and Elsa froze like ice. Anna seemed just as startled as Elsa, as she jumped and fixed herself into a seated position with the speed of a cat and agility of a hippo. Amongst her bouncing around, she righted her bangs, looking like she was caught red handed doing something she knew was wrong. Elsa pined for the contact back, she felt the cold draft in the absence of her sister's warm body. She hugged herself for warmth.

"H-hi dad," Anna said. It looked like she was trying to play it cool.

"Hi, girls," came the lower voice. Elsa remained silent, scarcely even looking at her father. She wanted to crawl away into a hole and hide, she wanted to fight the panic rising like the inexorable tide of the ocean inside of her, but all she could do was shake.

Then, in an odd moment of engagement, her dad asked "Anna, what happened to that Andy guy?"

Anna's demeanor hastily formed to defensive and she forced Elsa's hand into her own. That felt good. Almost offended, she said "I'm not with Hans anymore. Why do you suddenly care?"

"I'm still your father."

Teal eyes were narrowed like the blade of a sword. "Since when are you a father to us? You haven't shown any interest in our lives in years!"

Elsa, for her part, didn't really know how to react. Yes, it was odd that their father was asking about them, but it showed that he had some interest, right? Maybe he was trying to reach out a little bit? Or perhaps he was just pretending. Maybe he didn't care, maybe he just wanted to fill the silence. The last possibility that crossed Elsa's mind was a combination of both. He might have been trying to reconnect with Anna, but not her. After all, he did ask Anna a question, without really acknowledging Elsa's presence. To be fair, I didn't acknowledge him, either. In any case, Elsa thought that her sister might have been a little fast to jump the gun into confrontation there. But she supposed that's what years of drift will do to people. I'm just glad me and her stopped ourselves from drifting apart...

"I'm just gonna go to bed," came the man's voice.

"Yeah," Anna agreed caustically, "I think that'd be best."

They watched like hawks as their father turned and lumbered to his room, shutting the door behind himself. Once he did, Anna leaned in to Elsa's shoulder such that the side of her head was against her elder's deltoids and lightly clutched her upper arm. Elsa's heart fluttered.

She started rubbing Elsa's arm, making her shiver. "I'm sorry, I know that must have stressed you out."

Elsa thought for a moment. "It did, but- but not as much as it used to." After all, this was the first time that she didn't have to close her eyes for at least some portion of their argument.

Anna squeezed her sister's arm and the corner of her mouth swept upwards into silent approval. "I think you're doing a little better."

Elsa froze. Was that a lie? Like Anna had done before? "Do you really think so?" There was desperation knitted with skepticism in Elsa's voice.

The way Anna spoke was so direct, so serious, and so adoring that it eradicated any doubt of its truthfulness like fire vanquishes gasoline. "You just proved you're doing better."

Elsa smiled like a fool. She felt... proud of herself. For the first time in a very long time, she was proud of what she'd done. She was forced to wrap her arm around Anna, allowing the younger girl to lay her head on a chest with a heart beating so warmly that they didn't need a blanket. Anna settled in, putting her arm around her sibling's stomach, and both relaxed into the couch to paid attention to the third act of their movie.

And Elsa noticed the spark between her legs ignite once more, the feeling of Anna's head resting on the side of her breast fanning it like a billow. They finished their movie, and the entire time, to Elsa, it felt a whole lot like a date. She knew it wasn't, but she could dream, right? She compared it to her nights with Rapunzel, the kissing, her hand resting loosely on a thigh.

All the pretending just roused her up even more. When the flick was over and they were both on their way upstairs to get some rest, Elsa made a decision. "I uh, I think I'm going to take a shower before bed." I want to invite her to accompany me. Bathing was only a detail next to what Elsa craved to do in there.

With a mighty yawn, Anna said "Okay, have fun," as an innocent joke.

Elsa couldn't help the wry smile or the automatic "I will," as she grabbed a towel and reminisced about all the sights and sensations she so thankfully was able to experience that day. She locked the bathroom door, removed her clothes, and started the water running. She savored the feeling as she slowly slide her hand down her body, starting off before she even stepped into the shower by lightly rubbing back and forth on her labia. It was slick, already soaked from her evening with her sister.

She gasped as it pulsed, biting hard on her lip to suppress any unnecessary noise as she increased the intensity of her activity. She couldn't tell if the hot water or her arousal was steaming up the room as she worked a little deeper into herself, her fingers sliding easily and her legs becoming so weak that she had to support her weight with her free arm when she brushed her clitoris.

Elsa's labored breathing became erratic and loud, her eyes clamping shut as she imagined her sister's stomach and all of the lost opportunities with the sauce. They flowed in like a strike of thunder, jarring her mind and feeding the blaze between her legs. She stepped into the shower, laying in the tub and letting the falling water aid her fingers, able to pretend that every drop was Anna's doing. She gasped and got lost in ecstasy for God knows how long.

Elsa quietly exited the bathroom after rinsing off. Her knees were still wobbly from her main course and her cheeks were bright red, because she knew she'd see Anna soon and everything was still so fresh in her mind, yet it felt as rooted as an ancient tree.

Wearing nothing but a towel, she stepped into her room. She hadn't even thought about it, really, where Anna would be. But standing right there wasn't one of the places she expected. Elsa jumped back as she heard "hey, Blondie!"

"Ah-Anna, hi." She was already changed for the night into her usual gown.

Anna just kind of stared for a moment. It really put Elsa under the Gaze, she didn't exactly feel embarrassed, though. Okay, well maybe a little, but she also kind of felt excited. She was wearing nothing but a towel in front of Anna. She had to shake her head of thoughts before anything started inside of her. Too late.

"Well um, I'm gonna go brush my teeth while you change." Anna rushed out of the door before Elsa could answer or really even focus on her.

And Elsa was alone for the moment. She stepped into the closet and shut the door to make sure she wasn't walked in on. She removed her towel, put on some new underwear, and went to grab her nightgown. But she noticed something out of place. Elsa furrowed her brow when she saw a green dress that definitely didn't belong to her. She examined it and looked around. The more she looked, the more articles of clothing that didn't belong to her she saw. In fact, there was a rather large chunk of such clothes all hung up and placed together.

She was confused, but she gulped when she noticed some foreign underwear off to the side. Elsa's heart beat harder. She took a moment to collect herself, put on her night gown, and grabbed a shirt that clearly belonged to Anna.

She found said red head already on the bed, waiting when she left her closet. Before Anna could say anything, Elsa lifted the dress with her eyebrows raised expectantly. "Anna," was all she said.

Freckles hid behind the shelter of a red blush. "I um, I just thought, you know, it might be easier if I moved some of my stuff in, since I've been sleeping in here and everything it made sense, you know?"

Elsa bit her lip in what she hoped looked like thought. In reality, since her hands were full, it was a substitute for a pinch while she was checking if she was dreaming. She poured over the thought again and again. Anna's basically moving in with me.

"I can move them back, I didn't mean to intrude and I totally understand if you want your space-"

"Anna," Elsa sternly said. "It's okay, I- I don't mind."

The younger girl seemed to breathe a sigh of relief. "Oh good."

"In fact," the elder smirked, "I think it's a great idea."

That's when aquamarine eyes really lit themselves to teal. "Great! Now come to bed," came the demand.

Elsa, again, had to shake her imagination like a dog shakes off water. She smiled and climbed in, pushing up next to her sister and wrapping her arms around her. The proximity was beautiful torture. Anna lifted her head and leaned in until her lips were mere millimeters from Elsa's cheek, who was grinning in anticipation. Elsa could feel the trickle of fresh, hot breath on her face. It left a skin scorched red in its wake, causing tremors in Elsa's heart and dryness in her mouth.

This was one of the best parts of Elsa's day. She closed her eyes as Anna's lips touched the corner of her own. For just that moment, she lost all sensation beyond that singular point of contact, because that's all she needed.

And when it was over, she still had the beating heart of her sister right next to her as Anna lay her head down on Elsa's chest, settling in. Elsa sighed happily, but couldn't relax. She had to calm her over-wired mind down, shifting her head restlessly in a fight to find a comfortable position, mirroring the turning memories of parading by Anna in a towel and Anna's kiss in her head.

Making it even more impossible to find sleep was the younger girl's hand softly rubbing back and forth on Elsa's body. A tired, innocent roam no doubt, but it sure didn't feel that way.

Life was good.

It was easy for Elsa to spend the next day chipping away at her own work while Anna was in class. She had a lot to catch up with, after all. But now it was almost time for Anna to get home, and Elsa wanted to look nice for her. She had an idea about what to wear.

Elsa stripped her t-shirt and jeans off and tossed them in the hamper. She looked around her closet and managed to catch a glimpse of herself in the mirror. She wasn't completely naked, but she was exposed enough to really look at herself. She didn't want to face her own eyes at first, but was pleasantly surprised by what she found in them: light. Yes, she was still terrified of the world, and yes, she could still tell just by looking at herself, but there was something different about her.

She looked more confident, more secure, she looked stronger. She knew the glint in her eye was because of her now closer than ever relationship with Anna, and that was most likely also a big part of the reason for her dauntless appearance, but it couldn't be the whole reason, right?

No, Elsa didn't think so. She thought about how much she'd been through recently with Rapunzel, Hans, and Anna, and decided her mind must be just like a muscle. It starts to break down when you stress it, but once you take a rest it will heal stronger. Maybe it wasn't just Anna making Elsa a better person, but herself as well.

The girl gave herself a quick nod and spun to find what she wanted to wear, stopping for a few moments when she saw one of Anna's more lacy pairs of underwear. Her mouth went dry and heart felt rigid. She eventually refocused on the clothes that Anna had taken upon herself to move in. Well, since she felt free to put her stuff in my closet...

Blushing and a little nervous about doing such a thing, the platinum blonde reached for one of her younger sister's dresses. She had to choose carefully, as Anna's bust was certainly smaller than her own and she didn't want any wardrobe malfunctions while wearing said article. She chose a modest, lilac purple dress. It was simplistic in nature, having no notable laces or belts, sporting a full length skirt, long sleeves, and a collar that was high enough that it covered the sternum.

Elsa checked herself in the mirror once again, approving of how well her bust fit in the dress. She had her usual lipstick on, and the dress fit her curves a little tightly, but nothing obscene. She could hear her nerves rattling like a maraca, as she was unsure of how Anna would react. She really hoped her sister would take it well. Good thing she didn't have long to agonize over every possible permutation of negative outcomes.

Just minutes after she put on the dress, Elsa heard a car door in their front yard, and she made sure she was as close to the door as she was comfortable with when Anna walked in. That's when Elsa noticed that, when Anna was in the doorway, she was more comfortable in front of it. She wore her normal jeans and t-shirt for class. "Elsa, I'm- what in the world are you wearing?" Her tone was far from stern, her lips were upturned into one red cheek in amusement and she had one eyebrow raised.

Elsa breathed an internal sigh of relief at Anna's reaction and let her worry morph into fuzz and butterflies all around her stomach. "Well, you saw fit to go ahead to move your stuff into our room, so I thought it was only fair."

Anna bit her lip with a devious smile. "our room, huh?"

Blue eyes widened and seared porcelain cheeks. "I m-"

"I guess that makes it our closet," the red head pushed, "and our clothes, right?"

Elsa was beet red, but her stomach was oozing warm honey and uplifting her heart on clouds. "I s-suppose it does," she played along.

With an evil grin, Anna said "be careful what you wish for."

Oh, I don't think I will be. "What are you gonna do? Wear my clothes to death?"

"I guess you'll just have to wait and see," Anna replied with mock hauteur.

Elsa was about to have a heart attack, she was sure. This was overwhelming, this was like sitting in a sauna in the middle of a hot tub. "I simply can't wait." Elsa took the following moments of silence to examine dilated blue-green eyes. What a lovely color it was, honestly. And after a few seconds of not even mice daring to break the silence, Elsa realized that her sister didn't have a response. Elsa had won. She grinned, a little gratified with herself.

But then she noticed a nervous tick, and she knew Anna had something on her mind before the girl even said anything.

"Oh, Elsa, I um, I spoke to Rapunzel." Anna was quite demure about what she was saying. She was kicking her foot against the floor lightly and clamping her hands behind her back. Her body appeared unable to sit still.

Elsa's heart dropped. There was a confusing mixture of dread and anticipation. At the same time that she wanted to know about what Rapunzel said, she didn't want to know. The emotions were like water and oil trying to mix. "Oh, um, h-how is she? w-what'd she say?"

Anna stepped forward, almost possessively. "She's doing okay, she said she'd- to give her a little more time and she'd- she'd call you when she's ready to talk again."

A lump formed in Elsa's throat. It burned and ached, and she noticed her eyes tearing a little. It wasn't from despair, at least Elsa didn't think so, but some sort of reaction to knowing that she hadn't, in fact, ruined a wonderful friendship. She actually felt a little lighter. "Th-thank you, Anna."

One side of Anna's mouth turned up and her eyes became as entrancing as a calm, evening fire. It was a look that made Elsa feel cozily at home, made her happy with her life, made her forget about her ailment, just while she was looking into those lovely eyes. "Of course. Anything for you." She paused for a moment. "Oh, and Elsa, you look amazing in my dress."

Elsa's heart fluttered and blushed. "Thank you." Anna looked more relaxed now, so the elder closed the remaining gap between them and softly hugged her. She could have made it tight like normal, she could have been extra careful to make it feel sisterly, but she wasn't. She made it soft and tender, she made it loving, she just hoped that Anna didn't understand the message that she was sending. Because if she did, she'd know about Elsa's feelings and everything would fall apart, like a house of cards in the wind.

Anna didn't seem to, because she purred and sank into the embrace, resting her head upon Elsa's shoulder. There were a few minutes of placid silence, only broken by Anna's soft, mellifluous voice. "So um, there this... thing coming up."

Elsa pulled back, hands on either one of her sister's shoulders, and raised an eyebrow. She couldn't help but be a little nervous. If there was a 'thing' coming up, as Anna so eloquently put it, it meant that Anna was going to go somewhere. And her demeanor boded well for the crawling discomfort atop Elsa's nerves. "A 'thing,' huh?"

"Y-yeah, a thing."

After remaining silent momentarily, the elder pushed "care to elaborate?"

Anna bit her lip and tucked some hair behind her ear, cheeks rosy red and once again taking a slightly defensive stance. Elsa choked on her heart. "Okay, this is gonna sound a little crazy, but please, listen, okay? I mean, it might still sound crazy but just hear me out."

Elsa gulped and nodded.

"So I saw this flier for this Christmas Ball coming up-"

"Christma-"

"Shh, listen," Anna snapped.

"Okay, okay."

"Anyway, a flier for this Christmas Ball that's happening at my school coming up and it looks nice, everyone's gonna be dressed up all n-nice, and I thought, well, I kinda thought it'd be fun to go with you." Anna's face was flushed like a drainpipe, Elsa could feel the heat radiating from where she stood.

But she was too stunned to focus on it. Anna wanting to go to a ball with her! It was as close to a dream come true as she'd ever experience, of that she was sure. It wasn't like it was uncommon for sisters to go together if they didn't have dates, at least it wasn't rare in the movies, but still! Elsa's dream, however, was squashed by the deplorable monster of her phobia as it was birthed into fruition. It wouldn't let her be happy, it wouldn't let her leave the house. A thick pain developed in her throat, like she was choking on something and her eyes began to blur and burn. "Ah-Anna I-"

"But the thing is," the younger girl continued, seeming to completely ignore her elder, "I know that you- well that it would be really hard for you to leave the house." She had Elsa's attention again, if only barely, over such a devastating internal strife. "So I thought, well I thought that we could have our own." Anna kept her head down shyly, but pointed her hopeful eyes up at Elsa's, chewing her lip like gum.

Elsa could only open and close her mouth, trying to talk, but failing. One minute ago she was near despair, but it was like her entire frame of reference was swirled around, disorienting her. Her phobia was eliminated from the equation, an un-needed constant tossed away as another equation was derived from her old one. A new, simpler, happier one. One based almost solely on her dreams. She was still crying, but it didn't hurt any more. "Y-yes, I'd- I'd- I'd love that."
