Decided to have my own go at an Elsanna week for once. It will be a nice challenge for me to post something every day, but perhaps it will get me back into the swing of things as my holiday break continues. After all, I still have Sucker Punch to update.

So…with that said, here's day one.

.:All I Want For Christmas:.

Day One: Mistletoe

Olaf hummed pleasantly as he skipped across the bridge leading from Arendelle's castle to the town square, where he was sure Kristoff and Sven would be. The snowman was incredibly excited for two reasons. The first being as simple as the fact that Christmas was only four days away, and it was sure to be a white one even without the help from the kingdom's queen. Snow had been falling non-stop since late yesterday afternoon and showed no signs of stopping anytime soon.

The second reason was perhaps why Olaf was excited the most, however. He had come up with the perfect present for the two girls he considered his family. Elsa and Anna had explained to him a week ago when the town first started mentioning this thing called "Christmas" what the holiday was all about, and ever since then, Olaf had been on a mission to become a Christmas expert. He had read nearly every book in the library on the subject, ranging from children's books, to historical textbooks.

Now, with all his gained knowledge fresh in his mind, Olaf had come up with the perfect gift. Giggling giddily to himself, he picked up his pace as he spotted the lumbering form of the Royal Ice Master and Deliverer up ahead.

"Kristoff! Sven!'

Kristoff spun around at the cry of his name and smiled upon seeing the snowman bounding up to him. Sven immediately got into a play bow position and, once Olaf was in close enough range, charged at him before scooping him onto his back, Olaf cheering the entire time.

"What's up, Olaf?"

"Oh, I just came up with the best idea for a Christmas present for Anna and Elsa!" Olaf explained. "But, I need help to get it, which is where you and Sven come in! You'll help me, right?"

Sven snorted in quick agreement, while Kristoff shuffled his hat upon his hair.

"Well, what did you have in mind, buddy?" he asked. "If easily accessible, we'll be glad to help."

Clapping his twig hands together, Olaf leaned over and whispered conspiratorially into Kristoff's ear. The blond immediately blushed, but then grinned, looking Olaf in the eye and nodding.

Crying in joy, Olaf hopped into the sleigh and pestered Kristoff to hurry up and take him wherever he needed to go.

In minutes, they were off.

"Anna? Have you seen Olaf?"

The princess of Arendelle looked in the mirror to see her sister standing behind her in the doorway, a puzzled expression on her face.

"No, why?" Anna asked.

"Well, he said he was going out, but that was hours ago, and I know he was looking forward to dinner tonight which is almost ready," Elsa responded.

Anna shrugged and went back to doing her braids.

"Don't worry about him, sis," she said with a laugh. "I'm sure he's with Kristoff and Sven."

"That's the thing though," Elsa said with a sigh, coming up behind Anna and helping her with her hair, much to the younger girl's mirth, "they've been back on castle grounds for a couple hours now, and I still haven't spotted the little guy anywhere."

Anna closed her eyes in bliss, basking in the feeling of her sister's fingers gliding through her locks. They hadn't done each other's hair since they were children, and now Elsa just comes in and gets right back to it like a pro.

It was both refreshing and painful to think it was like thirteen years of separation never happened.

"Well, I'm sure he'll turn up before dinner," Anna reassured her.

Elsa just gave her a distracted nod and smile, clearly worried for the snowman's being.

It turned out, Olaf did in fact show up on time for dinner. And he was even more exuberant than when he had left the grounds earlier in the day. Giggling and chatting animatedly over dinner—of which Anna, Elsa, Kristoff and Sven were all present for—he had both girls exchanging questioning looks throughout, while Kristoff and Sven just continued to engage him like normal.

It seemed like they were in on the whole thing almost…

Dinner came to an end shortly enough and, after Olaf's cry that it was delicious and everything he had been expecting, wanted everyone to come to the ballroom so he could show them something. Again, Anna and Elsa glanced each other's way, so they were unaware to Kristoff winking at Olaf as the snowman led them all from the room and Sven clomping off after the two of them excitedly.

"Olaf, what's going on?" Elsa asked as they entered the barren ballroom. "Why are you bringing us in…here…?"

The queen's question trailed off suddenly as she took in what was supposed to be a dark room before them. Instead, the room had been lit subtly with a few candles along the wall, a giant Christmas tree at the room's center lit to its brightest and decked out in the most festive of decorations, complete with a glistening star on top.

"Wha…?" Elsa was speechless and thoroughly confused as she hadn't instructed any decorations to be put up in the castle yet.

"Oh, Olaf, it's amazing!" Anna cried. "Did you do this yourself?"

"I mean, I had help from the maids and servants, but it was all my idea, yup!" the snowman responded proudly.

"What's the occasion?" Anna asked, since Elsa still seemed incapable of speech. "I mean, I know it's the holiday season, but the castle hasn't had a tree or decorations up in-."

"Thirteen years…" Elsa finished solemnly.

Anna looked to her sister and the sad, guilty expression she donned, and didn't hesitate to take the elder girl's hand in hers. Elsa squeezed back tightly.

"Well, that's reason enough, isn't it?" Olaf inquired. "This is our first Christmas together! All of us together! Not to mention it's your all's first Christmas together in years! We gotta make it special, right?"

Almost in complete synchronization, Anna and Elsa knelt down before Olaf and gathered him in a hug, hands still clasped together, and teary smiles on their faces.

"Thank you, Olaf," Elsa whispered.

"Yeah, you're the best," Anna agreed.

Olaf let himself bask in the warm hug for only a second before he was pulling away.

"Wait, wait, wait!" he cried. "This isn't even the best part yet! I have to get your all's present!"

Now standing and donning confused expressions, Elsa looked to Anna curiously.

"The tree wasn't present enough?" she asked.

Olaf shook his head. "Nope! Be right back!"

As he shuffled away, Kristoff motioned to Sven, and the duo began going after the snowman.

"We better go help him out," Kristoff explained to the sisters over his shoulder. "Be right back. Don't move."

"O-Okay…" Anna muttered.

When it was just the two of them in the large ballroom, Anna turned to Elsa.

"I can't believe Olaf put all this together for us," she said.

Elsa nodded. "I know," she agreed. "I can't believe I wasn't aware this was happening behind my back. I've been in the castle all day."

Anna chuckled and grabbed Elsa's other hand, giving them both a squeeze.

"He's a sneaky little guy, isn't he?"

Elsa grinned. "He sure is."

"You know…" Anna began, biting her lip and looking away from Elsa, which the older sister couldn't conceal her blush from the adorableness of the action. "If Olaf hadn't had done this tonight, I had a similar plan all ready for you Christmas morning."

"You did?"

This time, Anna blushed from the adoring and loving stare Elsa was gazing at her with.

Nodding her head rapidly, Anna continued, "Yeah! I mean, you're my sister, Elsa; I love you despite what's taken place the last few years or even months. Remember how Christmas used to be our favorite holiday as kids? Even more so than our birthdays? I wanted to try and make us experience that same kind of joy this year, now that we're…back together."

Smiling shyly, Anna looked away briefly, before chancing a glance back to Elsa.

"Was that silly?" she questioned after a while of Elsa staying silent.

Reaching up to cup Anna's cheeks, Elsa beamed, a lone tear trailing down her cheek.

"No, Anna, it's far from silly," she told her. "It's beautiful, and I'm so happy you haven't given up on us all these years."

"Of course not," Anna replied, wiping away the stray tear from Elsa's cheek lovingly. "You're my big sis, Elsa. I love you," she repeated.

Bringing their foreheads together, both girls allowed themselves to cry freely, love encircling them like the storm outside.

"I love you too, Anna," Elsa whispered. "We'll have the best Christmas this year, okay? Better than any we had as kids."

Anna chuckled. "That's a big promise to uphold, Elsa."

"But with a little help from us," another voice jumped in, "it will be."

Both girls jumped back from each other in surprise as a lone light shone down on the two of them. Looking up, they squinted against the light to see the form of Olaf hanging above their heads, slowly being lowered down to hover just above them.

"Olaf," Elsa snorted with a laugh, "how did you get up there?"

He grinned and wiggled his eyebrows.

"A little bit of Christmas magic," he supplied.

"More like a pulley thanks to me!" they heard Kristoff cry from a dark corner of the room. "Hurry up, Olaf; you're heavier than you look!"

Rolling his eyes to the best of a snowman's ability, he looked back down at Anna and Elsa.

"Ready for your Christmas present?" he asked. "It's from me, Kristoff, and Sven!"

Glancing to each other once more, Elsa and Anna slowly nodded, having no idea what to expect.

Glaring smile on his face, Olaf brought out from behind his back a gigantic clump of greens, decorated sporadically with tiny, white berries.

"It that…?" Elsa started.

"Mistletoe?" Anna finished.

"I did my research this past week, and decided this was the best present for you both," Olaf explained. "The whole kingdom knows of the true love that connects you both; what better present than getting to express that love once more?"

Anna blinked. "But sisters don't usually kiss…" Trailing off, she looked over to Kristoff who just shrugged and gave her a thumb's up.

Elsa, who had been unusually quiet during this time, was staring down at the floor so hard and with a blush so bright, she was surprised she hadn't spontaneously combusted yet.

That, or created a freak indoor snowstorm.

"Elsa?"

The quiet voice of Anna had her looking up again and at the cute face of her little sister. She felt her blush ignite tenfold when she noticed Anna had a similar redness to her own cheeks.

She was more privy to feelings of love and devotion than one may think of someone who had lived in complete isolation for over a decade. There hadn't been a day that had passed where Elsa hadn't thought of Anna in one way or another, and over the course of those years, as Elsa grew, she knew sometimes those thoughts crossed the line of what was considered "sisterly."

She knew it was immoral, but she also knew that she loved Anna so much. She wasn't just her sister; she was her anchor, her light in her darkest hour, her soulmate, and, after the events the past summer, her true love.

Still, this didn't make the scenario she now found herself in any easier.

The blonde was drawn from her thoughts when she felt Anna take her hands once again, pulling Elsa close until they were standing only inches apart. Now instead of staring at the floor, Elsa's line of sight was full of Anna.

"Elsa?"

Grabbing on to the angelic voice of her sister as she had done so many days and years before, Elsa found herself anchored in the moment and looked up into shimmering teal irises.

She couldn't stop herself then.

Crashing their lips together, Elsa poured all her suppressed emotions and desires into the kiss, full of such passion she thought it put all those erotic novels she was embarrassed to admit she had read to shame.

Anna had inhaled sharply the instant her sister's lips were upon hers, as she had merely been expecting to exchange kisses on the other's cheeks. That wasn't to say, however, that she wasn't pleased by this development. Unbeknownst to Elsa, she had felt similarly for her sister for as long as she could remember.

As the two relaxed and fell deeper into the kiss, the room around them faded away. Their arms wrapped around each other to protect them from whatever ridicule they may receive in the future, their lips continuing to meld their two souls together as one.

Anna grinned as she felt Elsa's tongue glide across her bottom lip.

Yes, this Christmas would definitely be their best one yet.
