It's been a long time since she'd set foot in this town.

Well, felt like an eternity. It's been nearly… five years now, since university had taken her to a distant country, and only now was she was travelling back home to see her parents and friends.

Anna stared outside the window, gazing into the frozen land beyond just as the train was passing over a bridge.

Arendelle was always beautiful in winter, and Anna was glad that she was finally home. There was never a valid justification for coming back, even with her family worried about her happiness and wellbeing, because the travel times were just too long, too tiring for her to even commit to return every year. She only relented because she knew it would be possible that she would never return to the frostbitten valleys of Arendelle and its' fjord after this time, with work offers from all over the globe starting to pile up.

Ha, she laughed glumly within herself. There was a good reason why she didn't want to come back. Wish I didn't love that girl who happens to live in Arendelle.

That girl who happens to be my sister.

"Anna!" She turned her head with a smile towards her parents, who were excitingly waving near the exit of the platforms of the train station. She started pulling her luggage towards her parents, who instantly mobbed and hugged her as she exited the barriers.

"Mum! Dad! I've missed you so much!" Tears started welling up in the redhead's eyes as she hugged her parents dearly. Maybe she should have travelled back each year. She really missed them.

"Oh Anna, you're back with us. Finally!" Her father grabbed her belongings. "Come on, let's head towards the car. We better move before another snowstorm mobs us."

###

The car was humming down the road, away from the station and towards a home long deserted. "Where's my eldest sister?" Anna asked, curious on where the platinum haired girl had disappeared to.

"Oh, Elsa has her own apartment now in Arendelle. She's quite successful with her IT business! She's always had her head in computers and everything not related with people." Her mother explained.

"She's coming back home for dinner tonight, though. It's been too long since we've had a proper family reunion," her father added.

Anna internally groaned and sunk her head into her hands. This was going to be great.

Just what I needed in my life. A platinum bombshell babe who's probably hot as fuck now that she's 26.

Like she wasn't hot at the age of 21.

###

Anna barely managed to stumble into her old bedroom before collapsing into the bed and passing out. The timezone difference had screwed over her circadian cycle, and she couldn't fall asleep on the plane or train. Being in economy class with screaming babies and cramped spaces didn't help.

So by the time she stumbled out, completely dazed and mumbling about something to do with potatoes, it was nighttime and dinner was being served. She yawned and stumbled into her chair, rubbing her eyes before realising who was sitting opposite to her.

Fuck, fuck, fuckiscles on a stick.

In all her confusion and jetlag, she forgot Elsa was over.

Elsa. The platinum haired girl with one of the hottest bodies in town, no, the world.

Anna would have shamefully crushed and asked her out, except there was just one, little problem.

Elsa was her elder sister.

"Morning, sunshine," Elsa teased as Anna opened her eyes wide.

"M-me?" Anna looked around for a moment before blushing and turning her head back. "O-oh! Yeah, m-morning too Elsa!"

Elsa smiled and Anna cringed. It should be illegal for someone to look that sunny. "It's nighttime Anna."

Anna just groaned and slapped her hand on her mouth. "You know what, I'm just going to close my mouth now and not talk."

For the rest of my life, while Elsa's around.

"Roast lamb, Anna?" Her mother offered different meats and vegetables to Anna, some which she refused, some which she accepted onto her plate.

She tried her hardest to concentrate on the extremely unappealing carrots and peas compared to the… extremely sexy minx sitting on the opposite side of the table.

As she was trying to pick at a pea, it went flying off the table and under her legs. She sighed. Typical life hating me. Better make this quick.

Anna couldn't help herself but catch an eyeful of creamy, delicious legs… oh my god, she's wearing shorts in winter… I'm the luckiest girl in Arendelle! She quickly grabbed the pea and headed back above the table, being careful not to contact it with her head. She's done enough of that for a lifetime.

The rest of the evening passed uneventfully, with small talk being made between the family members, with Anna telling them what had transpired for the last five years, and what had happened to Elsa and her family in the last five years.

But she couldn't forget the sight of Elsa's tantalising legs.

###

"You heading off now sis?" Anna was at the door as Elsa was readying up to leave.

"Yeah. Got to run my own business, you know?" Elsa laughed as she double checked everything. "Actually, one thing I need to give you…"

Elsa threw something shiny at Anna, and she fumbled to try to catch it. As she eventually recovered and had the item firmly held in her hand, she looked at it.

"A… key?" Anna looked quizzingly at Elsa.

"It's for my place. Come over sometime this week, and come over and catch up. It's been a while since we properly talked. I'll text you the address so you don't forget," Elsa smiled at Anna, who smiled back.

"Alright, that's my cue to leave. See you, sunshine," Elsa waved and sauntered to her car in the driveway.

Anna couldn't help but look at her sister's retreating figure into the darkness. It should be illegal. Her ass. Her legs. Everything about that woman is ILLEGAL. My god.

She headed back upstairs as Elsa's car pulled out of the driveway, disappearing into the darkness.

###

Anna grumbled as she looked up at the glaring digital clock. 2AM in the morning and I can't sleep because all I have in my mind is Elsa's delicious body.

She groaned as she knew she was soaking wet down there at the moment. It was almost dripping out.

My goodness, a mere two hours with my sister as company and I'm reduced to this already.

She made sure her door was locked, before softly padding back into her bed and plunging a finger inside her pussy.

Anna's breathing became shallow and she moved the finger faster, fasterfasterfaster as she was thinking of Elsa.

Elsa's smile.

Anna slipped another finger in as her breathing became more ragged.

Elsa's smooth, creamy legs.

Faster. Faster. FASTER!

She was about to explode.

Everything about Elsa. Her personality, her sweetness, her body, her EVERYTHING.

Anna silently exploded into her own subspace, her mouth opening but no sound coming out.

She slowly stirred, noticing that her fingers and sheets were soaked, but she didn't care. She was exhausted.

She turned over and fell asleep, with her thoughts lingering on Elsa.

I know it's unhealthy but I don't care.

###

Across the town, in a certain apartment, a certain platinum-haired girl was still awake, programming into the night.

IT suited the introverted genius quite well. Own hours, own workplace, and you get to choose your own co-workers (none, Elsa thought gleefully)!

But she wasn't awake because she HAD to work. She was working to try to distract herself from her particular thoughts of a redhaired girl that happened to be her younger sister. Her beautiful, funny younger sister, who just happened to turn her on.

Elsa growled as she tried to ignore the feeling in her stomach, focusing on complicated equations to ensure the program would work correctly.
