A/N: It's 5 in the morning. I can't write. I can't think. This smut suck ass. I hate life. I hate writing in third person. This thingy came from tumblr. I'm just a lazy ass so I decided to post it here too since it's icest. :) Good morning!

It'd been months since then. Since the love between two sisters darkened from sweet, fluffy sisterly love to lust and desire for each other.

The room of Elsa's was dark. The sound of panting and gulping could be heard.

It was way past midnight. And that time was the time when... well...

Anna's wrists were tied up above her, her legs spread wide open, her torso streak naked. A cloth was loosely wrapped around her neck. Her heart was beating in anticipation, teeth scrapping against her bottom lips as she stared at the dark naked figure looming over her. Teal eyes were going up and down as she observed the girl above her, straddling her as she sat down on her stomach.

Dark blue eyes looked down at the girl. In her hand was a riding crop, letting her fingers glide up and down the stick.

Anna couldn't see her sister's expression, but she knew how cold she was looking at her. It was as if Elsa was the queen, and she was the peasant. And Anna just couldn't get enough of the way Elsa looked at her. It made her feel dirty. But god, she loved feeling dirty.

"Elsa..." she sighed, arching her back and closing her eyes as she felt the tool in Elsa's hand glide down from between her breast and down her stomach.

"Shut it," Elsa demanded, letting the stick press against Anna's hot skin. But suddenly, Elsa was sighing and immediately stopped what she was doing.

Anna opened her eyes, just to see Elsa sitting by her side instead of on top of her. The riding crop was still in her hand.

"Elsa?"

The blonde looked at the naked girl, bitter and apologetic. Was she crying now? No, she couldn't be.

"I'm sorry, Anna..." she whispered. "We have to stop doing this. We'll get caught."

Caught? How nice.

For months, they'd been doing this every single night. There was never a time where they would get caught in action. Elsa was a gentle dom. She was careful about what she was doing. She'd ask something like this many times but... they'd still end up doing whatever they wanted to do. Anna was persistent and was very convincing. Because of that Elsa would always give in.

Things went well for both of them.

Elsa was just unsure that's all. All she needed was little bit of convincing.

Anna and Elsa stared at each other in silence until the tied up girl smiled.

"But I love you—"

"Anna, me too, but this is wrong!" Elsa shouted, her voice nearly cracking. She took a deep breath as Anna frowned.

"You don't want to do this?"

"I..." the blonde sighed. "I do, I really do. I want to do this as much as you want to. I can feel, see, hear, smell, how much you do, but we can't, Anna."

Anna bit her lips, knowing that right now, she could no longer convince Elsa.

"We'll get caught, my love."

Anna knew that. So she sighed and with her tightly tied up hands, she placed them on Elsa's cheeks, her thumb rubbing below her eyes.

"Then... if nothing else, just... just once more?" she whispered. "It'll do."

"Anna..."

"Please."

Elsa looked at the girl worriedly, but deep down, she knew she wanted to do this—to fuck her sister senseless. The blonde sighed and picked up the riding crop. Behind her, Anna gulped as she stared at the tool, not sure how she was feeling. Elsa could already feel Anna eyeing her with anticipation and smirked.

The blonde was smiling wickedly—though it didn't quite reach her eyes. "I suppose... one more time." And she got up from the bed, noticing that Anna's eyes were blank as it followed her.

Snap!

That got Anna to wake up with a gasp.

"Wake up."

That tone of Elsa's sent shivers down Anna's spine. Goose bumps formed and Anna was now purring. She always loved the way Elsa sounded at night. The cold, hard stares of Elsa's were back. She took a deep breath, trying to keep her cool.

"Are you ready slut?" she asked, voice soft but oh, sounding so rough to Anna.

With a bite of her lips, Anna nodded with anticipation, hoping that she wouldn't be moaning now just from Elsa's voice.

Elsa nodded behind the red head. "Get on all fours, my pet."

Immediately, Anna did just as she was told and got on all fours, facing the head board.

Anna was now blindfolded and she could feel Elsa's palm pressed against her back, fingers scratching harshly as it ran up and down her spine and around her waist. The cold breath of her sister against her ear was making Anna breathe heavier.

"Do you remember our safe word?"

Anna nodded.

"Good."

"Elsa..." she sighed.

"Mistress," the blonde whispered and all of the sudden, she smacked Anna in the rear once. The red head gasped and whimpered, feeling Elsa soothing the striking pain for a few seconds. "Remember that." Twice. "You are my pet. I am your mistress." Thrice. "Got it?"

Anna remained quiet, biting her lips hard to contain the moans that Elsa was trying to force out of her. She couldn't even answer Elsa even if she wanted to. And Elsa wasn't going easy on her this time. She was completely different this time. A good different—

"Answer me!" Elsa shouted, the riding crop snapping in the air as a warning.

"Yes!" Oh, Anna was loving this!

Snap!

And Anna gasped as the tool quickly made its way to her back, marking it red quickly. But slowly, the riding crop was gliding up and down her poor back softly. Anna was now gasping for air silently, loving the feeling of Elsa's cold fingers rubbing her rear, the cold riding crop against her hot back. She noticed Elsa smirking, and could feel her breath against her ear once again.

"Yes, who?" the blonde whispered, and suddenly Anna's head was pulled back painfully as Elsa took her hair in her hand and tugged hard.

"Yes... Mistress..." she obeyed.

"Good girl." Anna smiled, chuckling even. "Now, slut, what do you want me to do?"

Anna gulped, knowing exactly what she wanted. "Fuck me, Mistress."

"Fuck you?" she repeated. The riding crop was pressed against Anna's abused rear, circling around her abused skin. "How?"

And when Anna didn't answer immediately, Elsa tugged harder on her hair until strands of it were pulled off. Anna earned another smack from the riding crop and she moaned in pain and pleasure.

"Gods!" she screamed, biting her lips hard afterward to contain her scream from getting louder.

"How?" Elsa repeated softly, but was quite demanding. She didn't even have to scream at Anna to get her to talk.

"Please... fuck me with your fingers," Anna answered and she was already breaking into sweats, her skin growing hotter with each strike Elsa landed on her.

With a wicked chuckle, Elsa got behind her so that Anna's rear was in front of her, crotch meeting each other. She still had Anna's hair in her hands and oh, Elsa was feeling so satisfied by the red marks on Anna's skin. No, she didn't even feel bad for landing such hard strikes on the poor girl. She knew Anna enjoyed the feeling of it.

Between Anna's legs, she was already dripping wet anyway.

Elsa dropped her stick on the floor, and with her hand, she cupped Anna's wet pussy. The scent was driving the girl crazy with arousal.

She licked her lips, eyes darkening in desire.

"Mistress..." she heard Anna call desperately. "Please..."

But damn it, Elsa pulled her hand away, quickly making Anna groan in frustration. "Turn around," Elsa demanded. Quickly, Anna turned so that she was lying down and Elsa was sitting on her stomach.

"Elsa..."

"Mistress, you slut." And now, Anna had Elsa's fingers, wet from all of her juice, in her mouth.

Anna moaned, darting her tongue out, licking each fingers filled with her juice. She was even grinning when she heard Elsa purring at the sight of the obedient girl below her.

It wasn't long until Elsa pulled her fingers away from Anna's mouth and quickly replaced it with her sex.

"Mmgh..." Anna made out when Elsa was just sitting on her face. She couldn't see, but that smell... oh, that smell was certainly familiar. The taste was familiar too. And it was leaving Anna wanting.

Louder she moaned as Elsa gripped hard on her hair. "Lick, my pet," she demanded.

She began licking, tongue swiping up and down gently. Her mouth was covered in her juice, some even dripping down to her chin as she continued to please the dominant woman above her. A smile appeared as she heard panting and groans coming from her mistress. So she hurried, sucking onto Elsa's clit hard until she was making popping sounds.

And now, god, Elsa was grinding against her face and Anna was trying to keep up with her.

The harder Elsa tugged and the louder her moans were getting, Anna knew she was going to come any moment now.

With no care at all, Anna increased her pace, allowing Elsa's juice to drip all over her. She was sloppy, but suddenly, Elsa was shivering and she came hard.

"Anna!" she moaned. Her pet continued to lick her clean as she continued ride through her high. And now, Elsa was panting, getting off of Anna who was licking her own lips clean, still wanting more of Elsa's taste.

But oh, she needed to be cared for as well. She couldn't even take anymore of how she was throbbing down there.

"Mistress..." she whispered, feeling a cool palm against her cheeks and legs between her body.

"Now how should I reward my little slave, hm?"

Anna bit her lips, chewing on it until she could taste blood.

Fingers slowly trailed down from Anna's cheek to her stomach and were now, cupping on her sex, unmoved.

"You're so wet..." Elsa whispered. "What am I going to do with my wet little slave, hm?"

Anna was now arching her back towards the hand, but still it wasn't even enough to satisfy her. She knew Elsa was observing her closely, for she could feel her breath tickling her.

The red head couldn't even talk—

Suddenly, Elsa had her fingers on Anna's neck, holding her tightly. But it wasn't too tight so that she would be choking. Her lips met with Elsa's and their tongue was wrapped around each other.

"Mnnn..." Anna moaned, tears filling her eyes from frustration. And just as Elsa pulled away from the kiss, she started rubbing her core slowly and gently which left Anna even more frustrating. She needed Elsa to be harsh! To make her come suddenly, maybe even multiple times.

"Elsa... fuck," she gasped out, pulling her head back.

"Shut up," Elsa whispered and quickly had her lips latched onto Anna's neck, palm slowly moving down so that it cupped around her breast.

Anna was moaning, twisting and turning uncontrollably, wanting more friction.

"Elsa... please—Oh, fuck!" she groaned just as a finger entered her, slamming into her.

And harsh she was getting as Elsa pushed and pulled her middle finger into the girl suddenly, pressing against the wall every time it entered the tight hole. Anna could already feel Elsa staring at her, watching her reaction with those dark, cold eyes.

Anna was so desperate now, that she was grinding against Elsa's hand, wanting more friction.

She was close. So fucking close.

"Please... don't stop!" she begged, feeling Elsa's thumb rubbing against her clit harshly. Elsa didn't stop, which surprised Anna. Elsa would always stop, deny her from her orgasm, but this time—

"Oh... GOD!" Anna groaned as she shivered and jerked, coming long and hard. Elsa had to cover her mouth from screaming too loudly. Behind those blindfolds, Anna was tearing up as she continued to come and as Elsa brought her down from her high slowly.

And when she did come down from her high, Anna was breathing so hard almost to the point that she thought she was going to faint. "F-Fuck..." she breathed, jerking every now and then.

"Anna..." Elsa whispered, slowly taking her fingers out, her other hand swiping strands of her sweating hair to the side.

Elsa quickly untied the cloth that was wrapped tightly around her eyes. Anna opened her eyes.

The blonde smiled as she untied Anna's wrists.

"Are you crying?" she asked softly, bringing her palms to her cheeks. Anna shook her head.

"Do you want to talk?"

Again, the red head shook her head.

Elsa got off of her and lied down next to her, bringing the blanket up to cover both of them. Anna turned to her and let the blonde wrap her arms around her tightly, running gently circles on her back with her fingers. The red head stared at her sister's chest going in and out as she breathed and closed her eyes, enjoying the fingers on her back. She wrapped her arms around Elsa's waist and held the blonde close to her.

"Do you want to sleep?" Elsa whispered.

Anna nodded. "Yeah."

Elsa was now combing her sister's hair.

"Will this really be the last time?" Anna whispered. The blonde paused and looked down, still seeing Anna's eyes closed. She laid her chin on top of Anna's head and shook her head.

"No."

It was a short answer, but Anna smiled and nodded, accepting. "Good."

"You're tired. You should sleep," Elsa mumbled.

Again, Anna nodded. She didn't have the right amount of energy to start a conversation anyway. "Okay."

The blonde kissed Anna's forehead. "Good night, babe. I love you."

But Anna was already fast asleep in Elsa's comfortable embrace to even reply.
