Chapter 1: Birthday Girl

Beep, beep, beep, beep, beep.

"For the love of all that is holy," Elsa muttered to herself as she slowly lifted her head from her pillow. "It's freaking 9 o'clock on a Saturday, why the hell is my alarm…." After a few seconds the realization hit her, "its Anna's birthday!" Elsa was up out of her bed in mere seconds. This wasn't just another boring sit-around-the-house Saturday. Today could potentially be the best day of Elsa's life, and not just because the girls' mother was called into work today. Today was Anna's birthday. Elsa looked forward to Anna's birthday even more than her own. Elsa's 21st birthday had come and gone in the blink of an eye so she figured, what else is there to look forward to? Anna on the other hand was just turning eighteen, which meant she was now an adult. This was something Elsa intended to take full advantage of.

Oh man, today is finally the day. I can't believe that Anna is finally eighteen! Seems like yesterday that my parents were signing the papers to adopt her even though it was almost fifteen years ago. I know she's not technically related to me but we grew up together, shared every experience of our lives with one another. I need to focus today. Today could potentially ruin my relationship with my one and only sister, my best friend.

Elsa quickly got dressed, pulled her hair up into a tight pony tail, and tip-toed over to Anna's door. She gently opened the door to find her sister still sound asleep in her bed. Oh this is way too easy. Elsa carefully took a few steps and assumed a leaping position. One….two…three! Without hesitation, Elsa leaped onto the bed, landing directly on top of Anna. Out of pure reaction, Anna jolted awake and immediately swung at Elsa with all of her strength. Anna screamed, "Get the fuck off!" Anna's fist connected with Elsa's face, knocking her straight to the floor. Elsa fought back the overwhelming urge to scream at Anna. Son of a mother fucker! Elsa immediately started fiddling with her jaw, checking to make sure it was still where it was supposed to be.

It took Anna all of about three seconds to realize she nearly knocked Elsa unconscious. Anna rapidly crawled to Elsa's side. "Oh my God Elsa are you alright?! I didn't mean it! I thought you were an intruder and...and…I just reacted you know...please don't hate me!" The nervousness in Anna's voice made it seem as if Elsa was on her death bed. Elsa just sat on the floor giggling, continuing to rub the side of her face.

"Damn Anna, you have a mean right hook," Elsa said playfully. You're lucky it's your birthday or I'd return the favor you little shit. "I guess that's what I get though for trying to suffocate you with my body though. Any harder and you might have broken my jaw."

"Well I assumed you were trying to hurt me, so yeah I was trying to break your jaw…but I still feel awful. Are you alright?" The concern in Anna's eyes never left for a second.

How can I even be mad when you're giving me those big green puppy dog eyes? You are too adorable. "Well, I can still feel the left side of my face and my jaw is still in the same place so I think I'm good," Elsa teased. "Now," she stood up and offered a hand to Anna, "In case you've forgotten, today is your birthday, so where do you want to go for breakfast?"

Anna wasted no time taking Elsa's hand. She eagerly stood up and wrapped Elsa up in her arms, just about crushing her. "Oh you remembered my birthday!" Anna shouted out with joy. Elsa felt a sudden warmth fall over her and a stupid grin formed on her face. The smell of vanilla drifted off of Anna and into Elsa's nose. And here come the feelings again. She always smells so damn good. God I hope you feel the same way about me. Anna finally released Elsa. I didn't say stop.

"Of course I did." Elsa felt slightly offended. I always remember your birthday. I'm one of the few people that ever does. "I always remember your birthday. When I have the greatest sister in the world, it's kind of difficult to forget!" Elsa flashed a goofy grin at Anna. God I must look like a love-struck idiot right now.

Anna just wrapped Elsa up again, even tighter this time. "Elsa stop it you're making me blush!" she giggled.

"Anna, getting a little hard to breathe here." Not that I really mind being suffocated by the smell of vanilla…

"Oh sorry!" Anna loosened her death grip a bit. "Anyway don't kid yourself Elsa. How can I be the greatest sister in the world when you yourself are obviously a much better sister than I am?" Anna pulled away from Elsa and started rummaging through her dresser. Again, I didn't say stop. "I mean you're absolutely gorgeous." Elsa's face instantly turned bright red. You're pretty easy on the eyes yourself. What does that have to do with me being a great sister though? Eh, who cares?

"You are the sweetest person I've ever known, and I've come to know a lot of people. On top of that you always remember my birthday and you always manage to be here for me whenever I need you. I don't think I could ask for a better sister." Elsa's face could not be a brighter shade of red. I just want to kiss you right now. Elsa opened her mouth trying to compliment her sister back but her mind drew a blank. Say something you insensitive bitch! "Anna…" Before Elsa could mutter another word, Anna cut her off. "You know Elsa, if you weren't my sister, I would definitely make you my girlfriend," Anna said playfully.

Yeah I bet you would…wait what!? Did she really just say that? Well Anna…technically we aren't sisters so…go for it! Oh for the love of all that is sacred please go for it! Elsa stood motionless lost in her own thoughts. She's flirting with me right now…right? I mean Anna came out as gay last year so she's already half way there. I mean I guess she could be…

"Yoo hoo, anybody in there?" Anna stood in front of Elsa waving her hand left and right. Elsa quickly snapped back to reality. She became so lost in her own thoughts she hadn't realized that Anna had already changed. "When did you change?" Elsa said with a tinge of disappointment.

"Well while you were off in your own little dream world, I decided I wouldn't look like I just crawled out of bed before we go out in public. Don't sound so disappointed. It's not like it's anything you haven't seen before," Anna said seductively.

Doesn't mean I still don't enjoy it…

"What was that?" Anna asked Elsa. Shit did I just say that out loud!?

"Uhhhh…" Elsa panicked, searching for anything to say that would shift the discussion away from the awkwardness she had just created inside of herself. "I said…let's…uh…get going, I'm starving." Smooth move Casanova.

"Uh huh, sure," Anna said sarcastically. "One second, let me just go fix my hair real quick. Go wait downstairs and I'll be down in a minute, ok?" Anna's voice trailed off as she skipped off down the hall to the bathroom.

"Ok! I'll be waiting!" Elsa rushed down stairs and plopped herself down on one of the kitchen stools. Calm yourself Romeo. You're acting like you're going on a first date with some girl you just met. As much as I want this to be a date, it's only breakfast between two sisters. Two sisters that have done everything together since they were little. Two sisters that have shared countless memories together. Two SISTERS that are just going to breakfast. I don't want to be just sisters though. Elsa let out a long, depressing sigh.

Tonight is going to more difficult than I thought.

The first chapter was kind of short so there's not a whole lot to rate this story on yet. If you want to keep reading, fantastic! If not, I won't beg you to keep reading. Thank you for reading the first chapter! Next chapter coming soon :)
