Elsa was busy signing documents in her study. It was a beautiful afternoon, birds were singing, the winds were delicately blowing... All and all it was a very peaceful day for the queen of Arendelle.
"Elsa! Elsa! Elsa!" Anna shouted in excitement, kicking the door open, holding a giant book in her hands. Elsa didn't bother to look up. She kept her eyes on her documents, but she did let out a little sigh.
"Look! It's a big book it was catching dust at the back of the library!" Anna said, losing grip of the book but managing to hold it up again.
"Anna, I'm busy. This is really important," Elsa said distracted, dunking her quill in ink.
"That's okay, I will wait," Anna chirped. She watched her sister work in silence, only the quill could be heard in the study. Every so often Elsa looked up to see Anna still staring at her smile not withering, wiggling her eyebrows every time she caught sight of the queen. Elsa sighed, she didn't know her sister could be this creepy.
"Okay Anna wh-" Elsa started but stopped when she saw Anna toss all of her documents, papers and stationary on the floor so she could make room for the giant book, Elsa stared at her documents, now messed up with ink.
"Okay so I saw this book! And I was like what? This looks new cause you know me and reading, we go waaaay back! Anyway! This book apparently has metamorphic spells we can use, interesting don't you think?"Anna explained. Elsa sniffed, wiping a tear away, all her hard work gone.
"Anna the book sounds dangerous, we shouldn't tamper with things like that," Elsa said, watching Anna read through the book.
"Relax sis, this book just turn you into a uhm swan, an eagle, and a doggy," Anna said the last one with excitement. Elsa moved next to her sister to read the creatures.
"That's a Phoenix, A Human devouring vulture and that's a WEREWOLF!" Elsa hissed looking angrily at her sister, Anna simply shrugged.
"Eh, same difference. You work all the time! Don't you wish there's a way you can do stuff faster so you can play with me? Like having extra hands or something? Besides these transformations are temporary," Anna urged Elsa. She looked back down at her documents.
"Since it's temporary I guess we could try but how long is temporary?" Elsa asked meekly. Anna squinted trying to read the foreign language that their parents taught them.
"3 hours," Anna said excitedly. Elsa nodded. The princess flipped through the pages looking at all the creatures.
"What you wanna turn into Els? A chicken? Horse? Butterfly?, Oooh a tomato!?" Anna shouted the last bit with a lot more excitement then it needed. Elsa just drew the symbol on the ground required for the metamorphosis.
"Uhm something with a lot of arms, so I can get work done," Elsa said making sure the sign was the same as in the book.
"Gotcha! Hey how come you get to transform first?" Anna asked, still paging through the book.
"Because if something were to happen I prefer it happening to me than you, Anna, I don't want you ever getting hurt again." Elsa answered honestly. Anna smiled at her sister. Elsa did the same then she cleared her throat.
"I found something!" Anna shouted suddenly.
"What is it? Please no Bugs. I don't want to be a creepy crawly," Elsa said softly, shivering at the thought. Anna looked at the menacing humanoid creature in the book, four tentacles behind its back, long fork tongue and a devious smile on its face.
"It's an octopus!...thing " Anna said unsure, taking a closer look at the creature.
"An octopus? Those things have tentacles Anna. That won't help I need extra hands," Elsa said gesturing to her hands.
"Well it has human hands too, not gonna lie, this thing do look super creepy, want to find something else?" Anna asked. Elsa thought about it for a bit, since it's for a few hours it's okay.
"No go ahead, I can make use of those tentacles like grabbing things and smacking a guard on the face! I'm kidding of course. About the last part, I won't hurt anyone," Elsa said quickly, rubbing her arm. Anna giggled and read out the spell.
"Ho elbmuh sdog? Uhm nrut em otni a Ino tsaeb! Won!" Anna chanted three times, they waited and nothing happened.
"Nothing? Maybe the book is really old?" Anna questioned looking at the instructions.
"Oh well, it was still a nice experience with you, want to go get some lunch?" Elsa asked, smiling at her sister. Anna was about to accept but something else caught her eye.
"Elsa your foot! It's outside of the circle!" Anna shouted, pointing at her foot.
"Oh dear, Elsa said, putting her icy heel into the circle, then a beam of light engulfed Elsa's being. Anna shield her eyes at the intense light. Once the light stopped, Elsa was on the ground moaning in pain and agony.
"Elsa!" Anna cried out running to her side. Elsa levitated and let out a loud shriek of pain then fell unconscious. Anna called out to her sister but it was no use, she was out.
"You willingly put your sister in a spell that you knew nothing about?" Kristoff questioned. Anna nodded sadly watching over her sister resting on her bed.
"Anna did you at least find a cure or a reverse spell or something? Your sister could be in a coma for all we know," Kristoff said concerned. Anna sighed.
"I did, but there's nothing in the book. We just have to wait until the hours are up," Anna said sadly. Elsa got up, eyes still closed. This startled the couple.
"Elsa?" Anna called out softly. Elsa opened her eyes, sclera black, eye color red, pupils now snake like. Anna and Kristoff's eyes widened. Elsa looked around and let out a long sniff and sighed.
"I smell a female, and it smells delicious," Elsa said in a seductive demonic voice, looking straight at Anna with a toothy fanged grin, 10 inch tongue sliding out of her mouth, wiggling in the air. Then four tentacles burst out of her back, slimy and skin colored. Kristoff noted that the tips of each tentacle looked like a knob of a penis. He gulped concerned for Anna's safety.
"Uhm, Anna what did you turn your sister into again?" Kristoff whispered.
"Uuuuh..." Anna couldn't find the words. Elsa's intense stare was making her mind go blank.
"I'll tell you what you turned your sister into!" Weselton suddenly shouted coming out of Anna's closet. Anna and Kristoff shifted their eyes from the closet to Weselton to the closet again.
"Where did you even-"
"You turned your sister into a sex demon! You stupid, stupid girl! She feeds upon female fluids. She will milk you and milk you until you have no strength left!" Weselton explained, watching Demon Elsa, tilt her head to the side and giving him a creepy smile.
"You're sister was a witch before, now she's a monster," Weselton said, earning a whack on his head by Anna.
"LIES! My sister is not a monster, she's just uh going through changes, besides this will only last 3 hours and she's harmless," Anna tried convincing him, walking over to demon Elsa, hugging her. Elsa purred and rubbed her cheek against Anna's. Kristoff and Weselton watched cautiously.
"See, she's harmless," Anna said smiling. Elsa bit on Anna's neck and began sucking on it, and Anna felt a little strange.
"Ooh... You're a little friendlier than usual, that's all good," Anna said laughing nervously. Elsa placed her sister in front of her on the bed and fondled her breasts.
"Uh, yeah that's a little too friendly, Elsa," Anna said fighting back a moan, trying to get her sister's hands off her clothed breasts, but her grip was too strong.
"Alright that's enough!" Kristoff warned. Elsa looked his way and hissed like a snake, and Anna managed to break free and crawled to Kristoff and Weselton.
"Yeaaah, Elsa isn't herself," Anna confessed, brushing her dress off from the dirt. Elsa hissed and eyed her sister like a predator ready to pounce its prey.
"Quick! We need to kill her before she gets fluids from you in order to get stronger!" Weselton said drawing his sword, Anna swiped his sword from him and threw it out of the room.
"Young Madame! That was a limited edition!"
"No! We are not killing my sister!"Anna yelled angrily at Weselton, poking his head with every word.
"Anna watch out out!" Kristoff shoutes. Anna caught the tentacle just in time before it could launch right at her face. It was now wiggling around in her hand. Anna tried crushing the tentacle in her hand that caused Elsa to moan.
"Ha! That's what sword training does! Gives you 20/20 skills," Anna said smugly. She didn't see the second tentacle come from under her dress and sliding into her undergarments.
"What in the world!?" Anna shouted alarmed that something squirmed inside her underwear and trying to make its way inside her private area. Anna was so distracted that her grip on the other tentacle loosened and pushed in her mouth, down her throat. Anna gagged at the intrusion, pumping down her throat and the third tentacle lifted her from the ground. The tentacle inside her undergarments shoved inside her pussy, squirming inside her, stimulating Anna's sex. She let out a moan and so did Elsa.
"Anna!" Kristoff yelled, but was pushed out the door along with Weselton by the fourth tentacle, then it closed the door and locked it.
"Do not interfere!" Demon Elsa spat irritated, then smiled at pumping inside her sister's mouth and pussy. Anna tried to pull the tentacles out of her mouth and intimates but it was too slimy. Elsa ripped off her ice dress in retaliation of the heat radiating her body, so now she was just in her ice bra and panties. The sex demon closed her eyes, feeling her tentacles absorb the saliva in Anna's mouth and her juices inside her cunt. Anna was a moaning mess, the tentacle pounding and squirming around inside her was getting her off pretty fast. Elsa took her tentacle out of her mouth and wrapped it around her sister's waist so she could push Anna into the other tentacle pounding into her.
"Aaah Oooh fuck! Kris Aaah! Hel- Aaah!" Anna moaned out trying to call Kristoff for help.
"Don't worry Anna! Weselton and I will go find a cure in the book in the study, plus we will come back with some help! Okay!?" Kristoff yelled from outside the door.
"Kriaaaaaaaaaah! Aaaah!" Anna let out a powerful moan from her intense orgasm.
"Glad we understand each other, c'mon old man!" Kristoff shouted, bolting away along with a reluctant Weselton.
"Yessss more! More juices!" Elsa hissed excitedly , still pumping inside Anna's soaked pussy, then dropped her body on the ground and pounced on top of her. She growled and ripped off all of her sister's clothes, all that was left was her boots. Anna mustered up the strength to talk to her sister.
"Elsa, please stop! Look what you're doing to me I'm your sis-" Anna stopped, feeling Elsa cup her pussy then began rubbing her clit with her thumb, up and down slowly earning delicious held back moans.
"That's better, all I need is a little juice to make me stronger...soon you won't be able to resist me." Anna felt a tentacle make its way inside her once again."I'm going to use you to power me up so I can rule the world and then destroy it," Elsa said huskily. Anna tried to get up but Elsa pinned her down hand on each wrist, knee on each thigh holding them open to pump her tentacles inside her. She couldn't do anything. She felt two tentacles squirm inside her pussy, filling her up and then pounding harshly into her.
"Aaaah! Aaah! Aah! Noo! Aaah!" Anna grunted trying to get free. Elsa smirked down at her, watching her breasts bounce with every harsh pound, then stopped the pounding to gather more juices inside by squirming around inside her. Anna stopped struggling when she felt both tentacles squirming inside her.
"My tentacles are a combination of a penis and a tongue inside you, so feel free to orgasm again for me, sister," Elsa purred emphasizing her role as the sibling to her sister who was now noticing how good it felt having slimy tentacles squirming inside her. She began moaning and arched her back.
"Oooh, looks like you like me inside you. I told you, you're resistance will be gone and you will be mine," Elsa breathed against her neck.
"Kristoff Hmmm," Anna mewled. She felt herself about to cum for the second time. Elsa wiggled her tentacles more vigorously inside her, smooth and gooey all inside her, giving her intense pleasure.
"Aaaaaaaaah Oooh Yeaaah!" Anna moaned, arching her back lifting Elsa from on top of her. Elsa kept the tentacles inside her, slimy pleasure taking over her mind. Anna couldn't moan, she was now lost in her own ecstasy shaking all over, mouth agape, eyes fluttering.
"Do you like the way I'm filling you up Anna?" Elsa asked, sitting aside from Anna, since she wasn't resisting anymore.
"Elsa, please snap out of it," Anna half moaned, she couldn't concentrate with the tentacles still squirming around in her drenched pussy. Elsa licked her lips feeling her body become stronger with her sister's arousal, but she needed more.
"Answer my question, sister," Elsa said darkly, squirming her tentacles deeper inside her sex. Anna's eyes widened and she gasped.
"Oooh fuck yes! Yessss!" Anna moaned smiling like an idiot at the feeling. She opened her legs wider willingly, trying to get to her third orgasm. Elsa's smile became monstrously wide in delight, eyes glowing bloody red. She slowly slipped her third tentacle inside her sister's wet open mouth. Anna willingly sucked on it, making the demon moan. The fourth went up her ass, luckily the tentacle was slimy, lubing up her puckered asshole, then began wiggling inside her, digging deeper into her tight anus. Elsa began to grow slightly more muscular, tentacles getting thicker inside of Anna. She moaned when she felt her pussy being stretched out a little, third orgasm destroying her train of thought, eyes beginning to glaze over.
"Oooh yeah, that feels good, you willingly help me devour your world? I'm so grateful I shall provide you with many pleasures like this, just know that once I get powerful I will kill everyone by ripping them to pieces! And feasting on their organs! But not you...you are my power source little Anna," Elsa explained in demonic voice yet again, drool dripping on Anna's toned stomach. She arched her back feeling her fourth orgasm wash over her body, the tentacles again prolonging the climax with its intense squirming. Her body shook like crazy and this time her eyes rolled to the back of her head. She couldn't comprehend any thought at that moment, all she could do is concentrate on the tentacles wiggling, making noises inside her body. Elsa smirked at the sight.
"You're lucky, this Elsa cares for you, I would've destroyed your body ending your life with pleasure, but I prefer you alive for pleasure, Oooh fuck!" Elsa moaned suddenly, shooting her thick load down Anna's throat. Warm cream shot up her ass and a double dose of spurts shot up her pussy. Anna swallowed what she could and felt the warm goo up her anus and shooting hard inside her, giving her jolts of pleasure inside. Anna laid slump on the ground taking all the load she can. She loved this. She wanted this.
"God that was amazing, I can feel more powerful by the minute. Let's get you all pumped up again," Elsa panted then smiled devilishly at Anna. Anna only stared at Elsa through half lidded eyes, then she felt wiggling inside her pussy and ass, throat fucking her as well. Anna sighed in complete bliss, eyes glazing over again, legs wide open, arms spread out doing nothing to fight off her sister, loving every moment of it. Elsa grew more muscular, teeth now sharp and skin paler, silently watching her sister getting fucked by her tentacles.
"Heeyaah!" Weselton shouted after the four royal guardsmen broke down the door, charging at Elsa with his sword slicing her but the sword broke in two on harsh contact of her skin. Everyone gawked at Elsa's somewhat invulnerability. Elsa looked at Weselton unamused. Weselton gave a nervous laugh and hid the sword behind his back. Elsa smiled and flicked Weselton away. He flew past all the guardsmen and Kristoff and smashed hard outside the room against the wall, leaving a dent in it.
"Elsa! Stop this madness right now! Or else!" Kristoff shouted boldly. Elsa rolled her eyes and got up revealing she was now a few inches taller than them, her eyes began to glow an intense red, illuminating the area in which she was gazing in red.
"Or else what!" Elsa's demonic voice boomed, they all stared at her in complete fear, and one of the guardsmen ran as fast as he could.
"Or else-" Kristoff voice cracked he cleared his throat."-Or else this!" He shouted, dousing the muscular demon with some liquid substance. Elsa began screaming in pain, freeing Anna of the intense fucking. Elsa screamed, flesh burning and then fell unconscious on the ground. Anna's pussy was throbbing, burning with desire, she needed more, she craved more. But it was over. Her body ached and was exhausted.
"Anna are you alright?"Kristoff asked concerned, throwing a blanket over Anna's naked body.
"I'm fine just a little sore. What happened to Elsa?" Anna asked, voice sore from moaning the entire time.
"Oh, she's under a sleeping spell. It should last until the time is up."
"Oh," Anna said simply, watching the guardsmen take her sister away with great difficulty given her size, knocking her head numerous times against the door frame.
Elsa was in a dungeon cell, arms and legs shackled, tentacles tied up. She sighed in defeat on her knees. She heard her cell door open and in came Kristoff in his pajamas and Anna in her nightgown.
"Oh great, what? You guys came here to mock me?" Elsa said darkly, still in a demonic voice.
"No we came here to check up on you, just 30 minutes left then you will be back to normal," Anna said smiling, Kristoff nodded and Elsa chuckled at the claim.
"Please Anna, you just came here to get one last fuck session with me," Elsa husked, raising her eye brow. Anna blushed and Kristoff looked enraged.
"No way! You are one sick individual for letting Elsa molest her own sister like that! And I can assure you she did not enjoy it!" Kristoff defended. Elsa laughed demonically.
"You're just jealous because I made her pussy soaking wet, oozing for more and you can't even make her pregnant!" Elsa yelled in her demonic voice excitedly, mouth stretched out when talking to Kristoff. He stormed out of the dungeon in pure anger. Anna was about to leave until...
"Anna," Elsa called seductively. Anna turned around and saw her sister's extremely long tongue wiggling in the air, then retracted in her mouth looking somewhat normal.
"Don't you want that in you're pussy Anna? I know you're wet, I can smell it," Elsa urged in a seductive voice. Anna closed her legs and bit her lip.
"Come to me Anna, I will make you cum. Hard.," Elsa whispered the last part. Anna walked towards her. She couldn't fight it. She wanted it to squirm inside her again. Never had she felt that before. No normal person could do that to her. She craved the feeling. She need it again. Elsa let out a demonic chuckle, then Anna pulled down her panties revealing her soaked cunt. Elsa licked her lips, then shoved her long tongue inside Anna's cunt, licking around inside her.
"Oooh fuck yes! Yes! Yes!" Anna moaned looking around if someone saw them and then bucked wildly into Elsa's abnormally long tongue. Elsa smiled, she was getting stronger, almost strong enough to break free.
"Ooh Yeaaah ooh yeah! I love sex demons!" Anna giggled then bit her lip, wrapping her leg around the demon's head, bucking uncontrollably. The slippery wet tongue swirled and slipped inside her, licking every little detail inside her sex, digging deep inside her. Anna couldn't believe how amazing it felt. All the tickles and jolts of pleasure was overwhelming. Her orgasm came pretty quick but lasted longer than it should.
"Aaah yeaaaahahahaha!" Anna laughed in her moan, tongue sticking out, orgasm blurring her mind from thought, arched back, eyes rolled back. The tongue was still vigorously moving inside her, licking up all the juices inside her. Elsa grew again, destroying the shackles and growing an extra two tentacles. She took her tongue out of Anna's drenched snatch and shoved three thick tentacles inside her stretching it out and filling her up. Anna moaned loud in delight. Elsa held her up with two tentacles and sixth slithered up her ass, they all squirmed furiously inside Anna.
"Yeaaah ohh yessss," Anna slurred, giggling like an idiot, drool dripping from her mouth onto the floor, eyes still white from being rolled up. Her orgasms lasted longer and were closer together. Elsa watched the drool and juices dripped from the body, smiling that she becoming more powerful.
"30 minutes are up. I guess I'm too powerful to turn back. You haven't read all the pages have you Anna? Don't feed the animal! But I have you to thank for providing with me endless amounts of energy." Elsa chuckled, staring at Anna's now brain dead face still in glee from all the slimy tentacles inside her stretched out pussy.
"After I'm done here, we have a world to destroy," Elsa said darkly, growing more demon than Elsa.
