(A/N: So! I decided I wanted to do this, so here it is. This is the scene in chapter three of this story when Elsa states that all she wants to do is fuck her sister.

So, she does. Don't go too hard on me, I've never done something like this before – and if it's not your cup of tea, then don't read it! No one is forcing you. :P)

Warning: This chapter alone is making this story M rated.

Disclaimer: I do not own Frozen or anything affiliated with it…could you imagine the possibilities, though?

"What are you – oh my – "

Elsa had taken off her robe to uncover a rather revealing outfit, showing as much skin as possible while temptingly covering her up.

Anna gasped – who could blame her – as Elsa slowly sashayed over, running her finger over Anna's arm; Anna was beginning to twitch uncontrollably.

Seriously though, who could blame her.

She smells so nice…strawberries, I think, and – oh –

Without hesitating, Elsa had Anna underneath her as she straddled her sister, fingers twirling her hair as she tenderly planted kisses on various spots of her neck.

Not caring about any permission being granted whatsoever, Elsa began to move in and take off each and every button on Anna's shirt. Soon, her younger sister was in nothing but her skirt and her bra.

Licking her lips, Elsa leaned in and whispered into Anna's ear.

"All I want to do with you is to fuck you right now," she muttered, running her hands all over Anna's body. Getting a satisfying moan out of it, she smirked against Anna's lips and continued to kiss her sister, halting only to tease at her skirts.

With Elsa on top of her, half nude and half insensible tigress, Anna had no way out of it.

Nothing had turned her on as much.

"Elsa," she mock whined, "this isn't fair."

"Life isn't fair, honey," was the response she got. "So why should I be any different?"

In one swift motion, Anna's skirts were nowhere to be seen. Elsa grinned deviously. "That's so much better," she murmured.

Once again, Anna found herself pushed up against the wall with Elsa's tongue in her mouth. The queen kissed her senseless, sucking out any sort of dominance lingering in Anna.

For the hundredth time, Elsa began thrusting her hips into Anna's, only harder and faster this time. She continued to cup her face and explore her mouth with her tongue until –

Elsa gasped and sat back with a triumphant smirk on her face.

"Oh, Anna," she teased, "is someone getting…wet down there?"

Anna flushed, turning a deep shade of burgundy. "It's nothing, uh, it's – oh!"

She felt Elsa hand creep down and massage her core, and she gasped, unaccustomed to this new sensation.

"Tell me how much you like my finger in there," Elsa cooed softly, and Anna moaned. "Please…please don't s-stop…"

Elsa had no plans to at all. She forcefully ripped Anna's shirt off of her back, exposing a thin bra.

Elsa liked that.

She liked it when Anna wasn't wearing a bra even more.

So off it went, hitting the floor as Elsa carelessly flung it behind her back.

Now all Anna had on was a slender pair of panties. Wanting to change that, she reached up to the clasp that held Elsa's bra together, but she shrieked as the queen pushed her arms above her, tying her wrists to either bedpost with a hidden rope.

Elsa smiled, satisfied with her work. "You may be the princess of a whole kingdom," she spoke with a smirk, "but you're mine right now."

Anna was terrified of Elsa – she was never terrified of her own sister, but now was a whole different experience.

It was different – but it was a good different.

"E-Elsa – oh!"

The queen, hungry as she was, bent down and began to lick on Anna's pert breasts, causing the princess to emit a submissive moan. "You like this, don't you."

"Elsa – oh, Elsa, please – ah!"

Tongue tickling one nipple and hand caressing the other, Elsa looked up and caught sight of Anna's mouth twitching, eyelids fluttering as she silently urged Elsa to go further.

It was all well and good, but Anna wasn't the only one getting pleasure.

Ceasing her actions, Elsa cupped her sister's cheek. "It's your turn, now," she teased.

Tilting forward slightly, Elsa held her own breast in her hand and lowered it to Anna's mouth, whose tongue was now out and ready to please the queen.

"That's right, Anna – oh, fuck."

Hands still fidgeting behind a tight bond, Anna tickled the nipple in front of her, sucking on it as she moaned, for Elsa's right finger was still deep inside her cherry.

The older sister had almost forgotten about it, but she was aware now, not hesitating to slide it in and out, causing Anna to squeal softly, lips still against Elsa's nipple.

Removing her hand from Anna's cheek, she tilted her chin up to meet Anna's obedient gaze. "Good girl," she said through a smirk, and not a second later their lips crashed. Elsa's tongue was once again exploring Anna's mouth, ceasing only to slide slowly against the opposing tongue.

After minutes, Elsa pulled away, licking her finger. "You really wanted that, didn't you," she said after awhile, smiling as she removed the ropes from Anna's wrists.

As soon as Anna was free, she had pounced the queen, and Elsa yelped. Anna was sitting on top now, grinning triumphantly as she stared down at her victim.

"You didn't think we were done, I'm hoping," she mock frowned. "Because it is my turn now."

Without a second thought, Elsa was stripped of all her clothing. The outfit was fucking sexy, but this…this is much better.

Not wasting a moment, Anna stick three fingers directly into Elsa's vagina, smirking as the queen gasped. "Anna – ah – "

Elsa's cries were smothered by the princess's lips – Anna had her own tongue traveling through the queen's mouth now. She continued to slide her fingers into Elsa's core, only smirking wider as Elsa moaned and gasped.

"Oh, fuck, Anna – "

"Language," the younger sister chided, but a smile was creeping onto her face. "Show me you're just as excited as I was."

Anna slipped her fingers out of Elsa's core and into the queen's mouth.

"Suck."

Elsa, gazing up at the princess with incredible compliance, began to do so, wrapping her lips around the fingers containing her own juices.

The sight alone was enough to get Anna even more excited, and she groaned softly as she felt everything grow wet below the waist.

"Mmm…Anna, let me help you with that."

Elsa leaned down and stuck out her tongue, gently rolling it across Anna's pussy, and the younger girl fought the urge to squeak loudly, and she failed miserably.

Despite the closed door, the shrill sound echoed throughout the halls, catching the attention of many servants.

Elsa was still deep into Anna's juices when a knock was heard.

"Queen Elsa, is everything alright?"

Silence.

"Oh, shit."

Elsa removed her tongue immediately and grabbed her own clothing. She pushed Anna into the bed and threw the covers over her.

Raising two fingers to her lips, Elsa turned to the door and opened quietly. "Hello, Gerda," she spoke softly. "Anna was taking a nap, and…she sort of had a nightmare just now – we're okay."

Gerda sighed. "Oh, thank goodness," she breathed. "I feared it was worse than just a dream."

In a way, it sort of was.

After a few more spoken words, the door closed again, and Elsa was once again in the bed with her sister.

There was a comfortable silence. Then…

"So," Anna said after a while. She reached over and took the queen's hand in her own. "You were amazing, Elsa."

Elsa chuckled, turning to the side to plant a warm kiss on Anna's lips. "You were good at following orders," she replied…
