~ Chapter Three ~

"OH." That one word was said in a deeper register, and brought the ruddiest flush yet to Elsa's face. Naked. Briefly, Anna felt tips poking at her own nude back, but then they disappeared again as Elsa obeyed the almost-command of her sister, allowing the jacket to slide down. Anna watched in utter fascination as it seemed to "float" behind her, moving up slightly and hanging in midair before it suddenly dropped to the tatami.

"Wow… they're really part of you."

"I'm naked," Elsa said, first sounding like a small child making an observation. She chuckled, then looked up and smiled. "I'm naked… just as you requested. Now what shall you do with me?"

Voice hallowed, Anna began to bring Elsa lower until they were both kneeling, one hand still in her pubic region as the other glided up and down from elbow to shoulder in a reassuring gesture and said, "Can I see you?'

"I told you," Elsa groaned, "I… don't have any control over whether or not they're visib-"

"Not that. I want to see you."

The flush returned in full force as Elsa smiled, eyes distant as she first shifted her legs out to one side, one hand supporting her body as she gazed up at Anna, now slightly taller. That position flattered her so much, and Anna wanted to take time to memorise it forever, but Elsa was already swinging her legs around to open them and place her feet on either side of Anna's. Then she leaned back…

And the world fell open to the younger sister as she gazed down upon pure perfection. Elsa was gorgeous; she'd expected as much, but now, she had all the proof she needed.

"Wh-why are you staring?" Instead of answering, Anna looped her arms under the angled thighs and pressed both hands against Elsa's hips, began caressing up and down the outside of her legs. "What, is it weird? Do I look strange down there?"

"There have been times," she began as she slowly shifted her own legs backward until she was on all fours. "Not… a lot of times, but a few… man, I hope you don't think I'm terrible."

"What is it, Anna?'

Freckles glowing, she leaned over and kissed the inside of one thigh. "Sometimes, when I would… get rid of my antsiness. Like, I'd be picturing some guy from school, or Zac Efron or something. Whatever worked that day, right? But then… when I'd get close to the end, instead of them, I'd be picturing… you." Swallowing, she continued in an embarrassed rush, "And I never thought about it, tried to ignore that, to ignore that my brain did a thing - it didn't have to matter, right?! Sometimes I'd think about a teacher at school that I'm not even attracted to, it doesn't have to mean anything at all! But it happened so often, I'd manage to keep you out of my mind a lot of the time, but once I even…"

When Anna didn't finish her sentence and had been given plenty of time to do so, one of Elsa's hands came to glide over her hair. "You even...?"

"This was just to crank one out! I was, um, I read… something about lesbians online, I clicked a related article or something…" Her breath was coming in pants that were increasingly closer to Elsa's sodden entrance, and they were both trembling now. "And that night… it started out with thinking about girls in general, just for whatever, to see; testing myself, how I felt about that… and then it wasn't just whatever, and it was you, and I was thinking about doing…"

Instead of saying the word "this", or anything more specific, Anna leaned forward and pressed her lips against Elsa's glistening flesh.

The reaction was instant and violent. Elsa's back arched and her lips sucked at the air, the hand on Anna's crown clenching hard, causing the younger girl to whimper. But it felt good. Everything did; Elsa tasted so different than she had been expecting, but still wonderful, and she wanted more. Her tongue flattened and began to glide from bottom to top, unsure if she was doing this correctly but enjoying her attempt all the same.

"ANNA!" the blonde gasped out weakly, hips squirming against the sheets as she was sampled, as Anna relentlessly traced over her fragile lips with a tentacle of her own. The sounds she was making! Even though she had just finished up against a practiced hand, she still found herself all too ready for another round; being this close to Elsa overrode her usual "one and done" policy.

And now, Elsa's friends were returning. Just tracing over her bare back, hooking lightly around her upper arms - encouraging her. But it seemed they wanted to be engaged more completely in some way, even if this was as much as they got.

"More there," Elsa panted when Anna's tongue poked up under the soft little hood at the stubbornly erect bulb of flesh that hid there. "NNHH! Y-yeah, that's it, more of that!"

"Mmhmm!" She didn't want to stop to speak more clearly, instead only obeying, attacking the sensitive nub with her mouth more and more, stopping to give the rest of her sex some attention here and there but mostly focusing on where Elsa wanted her to focus.

It was over in a few minutes. Anna was settling in to really go to town on Elsa, to even begin exploring with her hands once she established a rhythm - and Elsa was writhing and keening with pleasure, the heels that had suddenly appeared on Anna's lower back digging in for purchase. The invisible grip on her arms was tugging her down more, clearly telling her that even though Elsa had just finished… they weren't quite through.

"Did…" Face shining from the juices as she looked up at her sister, she cleared her throat and asked, "Was that good? Do you feel better?"

Nodding, Elsa lay there for a few moments collecting herself. "Anna, how… did you learn how to do that?"

"I didn't. Just tried it, based on what I read."

"No, you didn't 'just' read something and then… then do all that with your tongue so perfectly the first time!" As the ones on Anna's arm began to pull more tightly, drawing her higher almost against her will - almost - she chuckled and said, "My 'little friends' as you call them seem to agree; you have a natural gift."

"If I do, why are they taking my face away from that area?"

Elsa was shrugging, but already Anna was lying on top of her, green eyes staring down into blues, noses touching… chests. A bashful smirk crossed the younger girl's face when she realised this. "This is some nip-on-nip action right here."

"You… like that?" Elsa asked. Everything was a real question, even if it was also meant to goad Anna, to tease with words as much as sensation. Her hands came up and rested on her back, and Anna's eyes slid closed. "Oh God, I can't believe this is happening, after all that dreaming about it… hating the dreams…"

"Is it weird that… I wish I'd been dreaming that, too?" Anna breathed, ghosting her moist lips over Elsa's, and Elsa shivering when she realised what they were sharing. "My fantasies while getting myself off are one thing, but I never… I didn't think about you otherwise, that didn't seem okay - I already felt weird enough for-"

"You don't have to explain that part," Elsa chuckled self-consciously, even as tendrils began to slide up and over Anna's back, around her own hands. "We both get why we didn't think the thoughts were acceptable."

Nodding, Anna kissed Elsa again - and felt her pyjama bottoms being tugged downward, a little at a time. Elsa's hands were right where they had been, so there could only be one culprit. "Your, um, friends think it's not fair that you're the only nudist in the room."

"Just smack them if you're not comfortable with it."

"Nah, it's okay." Her voice sounded like it wasn't, but she meant her words; just because they had taken the choice out of her hands didn't mean she was against it, necessarily. Though feeling cold air against her backside when they were drawn too far down to cover it anymore caused her to suck in a breath of shock. "Oh… underwear too, huh? Cool, that's cool. F-fine with me."

"Is it?"

Squirming, Anna tried not to think about her already-wet sex being on display - since nothing with eyes was behind her, it didn't really matter. Technically. "W-well, it's only fair, right? With you already…"

They both moved their hips from side to side, almost at the exact same nanosecond. Slight rises of mons with the sparse hairs covering them ground together, and there was a purr deep in Elsa's throat from the sensation. The arms and the one tendril still on her back clutched tighter, as if the worst thing that could happen was ever letting Anna go.

"Here," Elsa snickered softly as one of her feet hooked over the remaining clothing and helped kick them free. "Better?"

"I guess." Anna was too focused on the tips of ghostly things trailing their way up the backs of her thighs, one for each. They definitely meant to make good on their intentions from before. The more she thought about it… the more she didn't mind. Or thought she might not, at least.

"Anna…" When she turned back, she saw the concern in her elder sister's eyes, and winced. "Are y-"

"Stop asking. I'm totally alright." One presence reached where her thigh met cheek, and she shivered all over. "A-ahh! Fine, I promise!"

"But if you keep-"

"Elsa."

"They're going t-"

"ELSA." That time, one slid up and over her entire cheek, and she groaned with need. "The more you ask, the more you make me nervous about how it's… how I'm gonna feel when it happens."

Shaking her head back and forth, Elsa just gazed up at her sister, at a loss. Anna really was willing to let this happen to her body, all to please her. Anna did know that, of course, but she could see the recognition finally hitting home.

"Oh…" Tears leaked down the sides of Elsa's face as she began kissing all over her cheeks, between her eyebrows, the end of her nose. "You're so perfect, I can't- I don't d-deserve…"

"You do. You deserve… not to have these things that you can't control, but since that's not an option…" Her smile was nervous but excited. "How am I supposed to complain just because being with you means putting up with a little extra love from them?"

Frowning, Elsa reached up - once she had freed that arm from under a tendril, much to its displeasure - and caressed the back of Anna's head. "Are you sure? Because you don't have to put up with them, with anything, you don't w-"

"If you don't quit that, I'm gonna reach back there and shove one in myself!" The way Elsa's face turned white as a sheet, even while the cheeks were splotchy and red - it made Anna feel ashamed of her own word choice. "Um… c-can we pretend I didn't say that? Makes me sound skeevy."

"W-we can, of course." Then Elsa cleared her throat and leaned up to kiss Anna again. However, as they did so…

They began to find their way to Anna's most sensitive region. It had only been a matter of time, she now realised; given that she wanted to be with Elsa more than she wanted to avoid experimenting with invisible limbs, there was little chance things would end up any other way. As their lips entwined, either side of her center was being trailed up and down, sliding on the juices already collected there. Anna bucked her hips back against them once, then wondered why she had done such a thing… but they seemed to think that was all the encouragement they needed to increase their speed, daring to dart in closer occasionally, flash over her labia so quickly that she almost thought she had imagined it. As she might have imagined this entire night.

"Ohhhhhhh," Elsa groaned out as she felt them for the second or third time, unable to restrain herself. Then she cleared her throat and smiled shyly. "Sorry, that… wow."

"So that f-feels good for you, too? Even though it's… them?" Anna asked as her hands came up to grip Elsa's shoulders. The blonde nodded, so she smiled down at her. "Then… try it again?"

A second later, they were back on her, and they were not darting away this time. Gliding up and down her, brushing the hood over her clit and making lazy turns when they reached up to her perineum to come back down where their attention was needed.

"Oh shit!" Anna was gasping. "Elsa! It's- y-you're so good!"

Down below her, the elder girl was thrashing back and forth the same way she had been when Anna was sucking and licking her nub earlier. So she felt that good when they could be allowed to touch. Elsa had been purposefully underselling the experience she was having to put Anna off wanting to relent for her sake. The only difference was…

Her expression looked positively hungry. When she'd been pleasuring Anna with her hand, she was glad to be helping, overjoyed they could be so close. When Anna's mouth was on her, she was coming undone, pleasure flooding her mind and blotting out all else. This was another matter entirely. The greedy tentacles had a taste and now they - and by extension, Elsa - no longer were merely "pretty sure" that Anna was what could slake their unending thirst. Having a target for it was making the desire rise to the surface in a powerful way.

"You're still holding back, aren't you?" Anna panted as they teased and taunted, took brief sabbaticals to glide down her thighs, spreading the juices around and making her feel more embarrassed, as if the world would be able to see her stripes of shame in the morning.

"M-maybe!" Elsa groaned. "But you're just… I w-want to enjoy this!"

"You are. That's not - nnnhhhHHH! - not why you're holding back! You're st- you're still afraid of going too far, aren't you?"

One of Elsa's hands reached up and clamped down on Anna's auburn hair, dragging her face down to devour it again - and this kiss told Anna everything she needed to know. It was the most desperate, unhinged one yet, tongue going straight into her mouth from the outset and finding places the indiscreet tentacle never had. Fingernails gouged into her back and she pressed her hips down harder against Elsa's, feeling skin rubbing on skin, the slight ripple of the tatami's woven rushes sliding under her toes as she tried to dig in for purchase. So she could do what? Her mind said, 'So you can take her virginity once and for all,' but that was ridiculous - because she didn't have the necessary equipment for that. But the way Elsa moaned into her mouth made her wish, for the one and only time in her life, that she did.

As if hearing her, one of the squirming lengths slid along her dripping crevasse, and she knew it pushed downward until it was touching Elsa's because the blonde's next moan was so loud that it forced her to pull away to complete it, panting noisily afterward.

"Ohhh, you sound so good," Anna commented as she ground against the presence. "I wish… I wish I could be inside you!"

"You… you can." One of the others wrapped around Anna's wrist, dragging it downward - and with no small amount of force. When Anna squeaked, Elsa bit her lip in worry.

"N-no, it just surprised me," Anna reassured her, kissing that bitten lip - which led the teeth to vanish so both lips could give Anna's adequate love. However, the message was clear, even after her wrist was released once her hand had been placed at their hips: she was to do for Elsa what had been done for her. And possibly more.

The minute her fingertips touched the folds, they brushed the presence that had been teasing it for them - and it drew back, flicking up and down along Anna's since its duties had changed. As Anna's touch moved faster, so did Elsa's, until they were both teasing at a blistering pace. Until…

"Are you… ready?" Anna said, positioning herself at the entrance, her palm just barely moving back and forth against Elsa's clit so she wouldn't lose steam.

"YES!" Elsa burst out, then slapped a hand over her mouth. "G-God, I didn't mean… to sound so…"

"So good?" She wiggled the finger she was prepared to enter with from side to side slightly as her own sex was mercilessly teased by the stray tendril. "Alright… here we go."

And she slowly slid inward. Elsa's body accepted her with open arms, and she felt so hot and tight on the inside! Seeing the blonde head fall back completely as she ululated with ecstasy was no small additional pleasure, but she was definitely all about exploring the inner walls that she had just discovered.

Which made two of them. No sooner did she actually have the chance to think "I really am inside Elsa" than Elsa was inside her - stabbing deep into her body. The action had been so swift and certain that she barely had a time to shriek with sudden pain before it was done, and she was wide-eyed and disbelieving.

The pain. That was it, wasn't it?

"O-oh!" Elsa managed to gasp as they both grew accustomed to being filled. "You w-weren't- you never- Anna, w-were you a virgin?!" A weak nod, and Elsa reached up and grasped both of her shoulders, shaking her. "Seriously? Why didn't you tell me?! You stupid fucking brat!"

Anna shrank back from the insult, completely shocked. Even when they were fighting, or during long stretches of silence between them, Elsa had never treated her that way. Never been so angry. "Wh… I didn't m-mean to hide it from you, I just thought you knew!"

"How c-could I?!" Then she jerked Anna down and crushed her in a hug, even while the length was wriggling back and forth inside of Anna, taking all the pleasure it wanted - and giving back tenfold. "You idiot, I never would have done it like this if I knew, if I had any clue!"

"It's okay," Anna breathed numbly. She could barely register what Elsa was telling her through the cloud of arousal, and past the knowledge that her cherry had just been popped - by something invisible, something supernatural that was attached to a relative. A secret. There would never be a "first time" story she could tell her friends as they all laughed. No, this would always be a story that would follow her to the grave.

"Damn it," Elsa breathed into her hair, shivering all over. "I… I don't know what to do!"

"Just keep going." Then she swallowed and pushed her hips backward against it, almost collapsing down atop her from the influx of incredible sensations. "O-OH! Shit, it's- WOW!"

Elsa's teeth dug into Anna's neck as some way to ground herself as she began to work on Anna, the one thick length squirming very slowly back and forth inside her body. The same was happening with Anna's finger, however - perhaps at this point more a product of nervous twitches than conscious effort, but deliriously good all the same.

And after a few seconds, it became clear the other appendages weren't going to let this be a one-tentillum party. They trailed down from caressing her back, one wrapping around one of Anna's thighs and pulling it further away from the other. Opening her up, spreading her out to be so much more easily penetrated. One slithered up from under their breasts and wrapped around them, then reached up to tap against Anna's lips; it had more than enough leftover slack to do so, it seemed.

There was no energy left in her bones to resist. When it dove into her mouth, she merely engaged with it as passionately as she had with Elsa's tongue, the comfortable warmth somehow completely different than the one buried in her sex, driving her passions through the roof. They really did feel fantastic, now that she knew what they were and that they belonged to the only person that would have been able to set her mind at ease about their very existence.

Already, she felt another finish building - that soon! Either it was simply the fact that she was being filled for the first time, or the knowledge of what was doing that filling… but she was definitely seconds from the dam bursting. She tried to use that finger to ramp things up for Elsa, to bring both of them off at once, but Elsa's groans were still pretty low and building compared to her own overwhelmed whimpers against the one in her mouth.

There was a final act that did it; Elsa pushing her up and off of herself so she could wrap her lips around the nearest nipple, the one that was not being squeezed by a doubly-busy presence. Even all her years of random occasional fantasies had never even dreamed up the possibility of putting a mouth there - and having her sister do it out of nowhere was enough to send her into a second orgasm.

An instant later, Elsa was pulling her mouth away and gaping up at her. "You sounded so… I don't know. Are you sure I wasn't hurting you?"

"Pretty fucking sure!" Anna laughed weakly once her own mouth was clear of its best friend, barely able to keep her eyes open. "You… oh wow, that was incredible! How… how are you so…"

"So what?" Elsa asked patiently, her tentacles all holding still and awaiting judgement.

"So everything."

Biting her lip, Elsa turned her head away, trying not to squirm back and forth from the finger still deep inside of herself. "Anna… I'm a terrible person for letting this happen. While I am glad you're enjoying yours-"

"Shut up and scream for me."

The wide, disbelieving eyes told Anna so much: that Elsa feared she was making a huge mistake, that she worried about their future now that this was happening. Worried about Anna's safety, her mental health, both of their ability to love someone else in the future. Not that Anna could let herself focus on those things at the moment, but she wouldn't forget about them.

For some reason, she had been expecting the one deep inside of her to withdraw once she orgasmed; it did not. However, she was still enjoying its presence to a lesser degree, so she wasn't complaining; just curious. Would it stay in there until she got Elsa to climax again? Maybe so. Her hindcheeks clenched nearby, feeling a thrill from how that changed the sensations inside of herself. Interesting…

And the tendril seemed to agree, twitching very slightly and prompting another moan from Elsa - followed by a moan caused by the fingertip as it curled up and in. Very shortly, she found a spot that seemed to make her half-sister literally spasm all over.

"AHHH!" Anna shouted when that spasm reached the presence within her. "Shit, that's- what is that?"

"M-my spot!" Elsa managed to bleat out, her legs rising again to rest upon Anna's hips. "Anna, you- MMMmmhhh, yeah, right there! More there!"

"Here?" Another test-tease that left the blonde a shuddering mess - which she felt inside, as well. "Oka-ha-HAAaay, th-that's definitely the spot for you!"

They fell to writhing against each other for a few minutes, occasionally joining their mouths but mostly staying apart so they could breathe. Of course, once the pace increased to a certain amount, it was decided that Anna didn't need to breathe through her mouth anymore when it was filled again, the familiar presence changing its tactic. Now it slid in and out of her mouth, going deeper and deeper each time. She noticed it moved even more enthusiastically when her tongue teased its underside, so at first she refrained. Then she found herself doing it continually, even though she had been not at all sure that was what she wanted. There was little question about that now.

When Elsa's hands again raised to Anna's back and clawed at it, eliciting a muffled groan from so deep in her throat that she was surprised any sound happened at all, Anna began to buck backward against the one deep inside of her, tensing her cheeks as she had before, testing the newness of that sensation. Not that she should have been doing any of this. Not that she didn't feel like a crazy person, encouraging two different invisible beings in her body to go deeper, move more. Pure madness.

And the madness did not stop there. One of them had been caressing over her thigh, her back, her calf… merely content to explore the areas of her body that were not the center of pleasure. Which threw fuel on the fire in its own way. Now, however, it seemed to be more interested in the pulsing that was happening as Anna clenched and released on a regular basis. And it poked around the tautly-stretched lips, as if trying to find its own way in.

"Mhhhgh!" Anna cried out, eyes wide as they looked down at Elsa. There was no way to tell her what she was thinking: that there was no way, no possible way two of them were going to fit inside of her! Attempting as much would only tear her apart!

And Elsa weakly nodded her understanding, even as much of a sweating, dazed mess as she was. The one that had been enjoying her body so thoroughly up until that point withdrew, giving Anna whiplash before she was penetrated again by a dry presence, accidentally biting down on the one in her mouth so hard that Elsa hissed in mingling pleasure and pain.

"S-sorry," Elsa managed to groan, pressing her lips against Anna's neck in apology for how sudden the switch had been. Then her eyes widened. "Oh… oh, I don't- Anna?"

As she began saying that and Anna wondered what the matter was, she found out an instant later when she felt the first one pressing inward again. Somewhere else. Another, completely different location.

"O-ohhh," the elder sister groaned as she pondered the new feeling. "Does that actually work?" One of her hands drifted down to grip Anna's pert, soft hindquarters, and the girl shivered on top of the shiver she had been in the middle of due to the initial teasing of the errant tip. How was she to know if that worked? That was beyond messed up! Another lewd thing she never fantasized about - though she'd heard of it before, of course. People putting things in places where things did not go. Except…

From what she'd heard, they did go there. Regardless of whether or not it was a good idea. A safe idea. Her head drew back and gaped down at Elsa, even if she couldn't speak she had to let her know that she was a lot less open to trying this than she had been anything else thus far. There had to be some boundaries!

But her tightly-clenched little orifice was already being teased and taunted by a hot, essense-coated tentacle. Not entered, not even prodded truly - ghosted over, as if petting that part of her. Hoping for another way in.

"Anna… shake your head if you don't want this," Elsa asked her urgently, even though she was in the middle of a series of grunts and moans herself, hips shifting from side to side to get the most out of the invasive touch of her sister. "I… I can make them do something else, I promise I will!"

Of course, Anna did no such thing. Scared as she was of how this would play out, she wasn't terribly scared of trying it in the first place. The idea was equally exciting, if she were honest with herself - at least, trying it was. So instead of shaking her head, she gave an extra-hard thrust of her hand up and into Elsa's body.

"AHHHH! W-well, I s-suppose that means you're alright with it!" By way of response, Anna nodded, smiling around the invisible girth in her mouth. Briefly, she wondered what that must look like to the woman beneath her… but then again, Elsa could see them. What did that look like to her?

All such idle thoughts were erased by the feeling of something pushing its way between her clenched cheeks. Very insistently. Without stopping.

"Relax your muscles," Elsa began to coach her in a shaky voice, petting her neck up and down. "It… it feels better, is less worrying." The question in Anna's eyes was so clear that no voicing was necessary, and it made Elsa blush all the way to her roots as she muttered, "I… w-would rather not specify how I know that."

"HMMHHGGHH!" Anna managed around the thing in her throat, utterly stunned by both what was happening to her and that Elsa had already, apparently, done this to herself. Was nothing sacred or taboo anymore?

Not if the presence already edging its way past the taut skin of her ass had anything to say about it. The sensation was so unpleasant, yet… satisfying, exciting. She both wanted it to stop and to continue, so different was it from the other one already diving in and out of her swollen cunt at a rapid pace. Most surprising of all, it was making her feel like she might actually be able to finish for a third time - which had never, ever happened before. Even finishing twice in one day had been something she only tried on a lazy afternoon one summer, when Elsa and her parents were out! Could she really do this three times in the same half hour period?!

And it was inside of her. Two - no, three of them. Throat, ass, and climbing up to the neck of her womb. If she'd had a fourth opening that experienced pleasure, it would probably be full, as well. Out of everything, it was her forbidden entrance that felt the most full, the thing slowly wriggling deeper and deeper. Why did this feel so good?! It wasn't supposed to - having one within her center should have been so beautiful she didn't need anything else. But since she was already being filled, already experiencing all these sensations…

"Ohhhh yeah," Elsa was moaning as her hips shifted against the rigid finger inside of her. "More - c-can you do two fingers?" When Anna raised an eyebrow down at her, her lip trembled and she breathed, "S-sorry."

Anna didn't have any way to tell her that apology was unnecessary other than doing as she asked - she drew back out and slammed two fingers deep into Elsa, prompting the three presences within her own body to shudder and squirm. Her eyes nearly popped out of her head at that - it was so much! TOO much! But denying she loved every second would only be robbing herself of the ripples of pure pleasure that were spreading outward from every fillable opening.

"AHHHHAAAhhhhh!" Elsa was wailing, nails still scratching up Anna's back, which made her tremble against the tentacles flying in and out of her lower region. The one in her ass was gentler, but not by much. "Anna! Anna, it's so good - you're so ffffffucking good, I can't believe- how did w-we wait this long?!"

"Mmmhh!" was all Anna could reply, of course. But she wanted to say more; to agree, even though she was so overwhelmed by all of the sensations that there was nothing she would be able to say if the thick presence sliding in and out of her throat would give her the chance.

"Your tight little body!" Elsa wailed, and Anna felt herself blushing, even though she should already have been doing that from their actions alone. "I d-didn't want to give those abominations the satisfaction, and now… and n-now- NNNhhhh, more! HARDER!"

Alas, it seemed that last word had a double-meaning. While Anna was ramping up her own speed, she suddenly found that everything pumping in and out of her body doubled its pace, punishing her body more than she thought it was capable of enduring. How she had gone from being a virgin to "all holes filled" in one night, she would never know.

Other than the answer being a simple "Elsa."

"YES! That's it, that's it, I'm- NNHh, I'm almost there, almost there, alm- almost there!"

And so was Anna. Despite all of the stimulation, she couldn't seem to reach number three, though - too worn out from earlier, or perhaps just needed prompting. Which Elsa's body seemed to sense. That fourth tentacle that had been content for so long to merely hold her legs further apart abandoned its post so that it could flash down between their bodies, rubbing against her clit and the wrist that kept bumping up against it with every reckless thrust into her wailing sister.

Then she realised something. It wasn't flicking only her clit; wasn't pointed at it. That was definitely the soft, lengthy area of the appendage up against her sensitive nodule, and not the tip. So where was it trying to-

"AHHHH, FFFUCK!" Elsa screamed in a voice almost an octave higher. "We d-don't both need one there!"

Asked and answered. Apparently, Elsa's body disagreed with her mind on what did and didn't need to happen.

Nothing further was needed for either of them. Scant seconds later, they were both moaning as loudly as was possible - even Anna, despite the thickness clogging her mouth as it slid in and out relentlessly. Her orgasm had her clamping down on both of the others, but she could barely distinguish them from each other anymore. Everything simply felt like the most bestial wildfire roaring under her skin, raw and untamed.

When their passions began to wind down, she felt them go limp inside of her. There was no change in their mass, but their actions settled, and they were simply there. Then they began to draw out a very gradual pace, for which Anna could not begin to express her appreciation.

"Hmnaaahh!" she gasped when her lips were exited, leaving a smear of saliva down her own chin. "Th-that was… Elsa, do you know what you just did to me?!"

"Are… are you mad?" Elsa asked her dazedly, smiling even through her concern. "You… sure didn't act like… you wer- AHH!"

Seconds later, Anna brought the fingers she had just roughly removed from Elsa's tortured muff and held them up close to their faces. "That will… teach you to be so mean." Then she licked her fingers clean, as Elsa purred in delight at the little show.

"Seriously," she asked after they were essense-free. "I… I told you to shake your head if… and you didn't, so w-was… was it okay?"

Anna relented and nodded. "Yeah, it was great! I just… I've never… wow."

"Yeah," Elsa readily agreed. "That's what I was gonna say."

"Can we… do that again?" When Elsa goggled at her like she was drunk, she squeaked, "NOT right now! If you do that to me right now, I'm chopping those things off!"

"Okay, good… that's… more sane." Wiping her brow, she raised the other hand to pet along Anna's back - prompting a wince. "Wait - your back, are you okay?!"

Anna nodded, slowly edging herself to the side - and wincing. "Oh… okay, um, my back will be fine, but all my muscles are super sore… ooh, that is… I'm gonna feel that in the morning!"

After a few moments, they settled against each other's nude bodies, and Anna could feel the lengths drape over her body. When she shivered, Elsa made a questioning noise, and she whispered, "No, it's… a couple of them went some, um… extra-dirty places."

"Oh." Snorting, Elsa pushed to a sitting position. "Whoa, head rush… I'll, uh, wash up. That does seem wise."

"You don't have t-"

"No, it makes more sense. It's… proper." Then she turned and began searching for her clothes. Anna watched her idly, enjoyed the view of her hourglass figure crouched above the mats, until she turned back to catch her staring. "What?"

"N-nothing," she said with a slight smile. "Just… damn, are you gorgeous."

And sitting there, nude and with both legs tucked under her, one hand leaned against the floor with the other clutching her own shirt, Elsa smiled seductively over her shoulder. And Anna Katsushika knew, even moreso than she had before all of this, more than she had understood while they were in the middle of making each other beg for sweet release.

There would only be her. Forever. Even if she decided they had done something unforgivable, and never touched each other beyond a simple hug again, even if they severed all ties… no other potential mate could even breathe the same air as her precious sister.

"Takes one to know one."

Rolling her eyes, Anna picked up her pillow and chucked it straight at the blonde head. "Get the hell out of here with that dad-line! GOD!"

The first thought that came to Anna's mind when she rolled over the next morning was, 'Why is my face on another face?'

Then she realised, of course. It was Elsa. They had slept curled up together, and in fact, one of her legs was tucked very slightly between both of Elsa's. She was purring with pleasure seconds later, burying her face in the soft neck. It was all real. All of it-

Then she started, feeling upward along Elsa's side. They were gone. All she found was armpit.

"Wh-what?!"

The sensations and single word were enough to wake the elder sister, eyelashes fluttering. As usual, she was the picture of perfection, even seconds after awakening. Yawning her dainty mouth, she looked upward and asked, "Hmm?"

"Elsa… what happened to your… 'little friends'?"

"What little friends?" In response to Anna's thousand-yard stare, the obvious fear that she had imagined the whole thing, she finally smiled slightly. "Okay, okay. I won't be that mean to you. But can I…" Another yawn. "Ugh, can I wake up first? Take a shower?"

"No, tell me! Why did you have supernaturally thirsty tentacles last night and now you're normal?!" When Elsa whimpered and fell limp, Anna hopped on top of her and began shaking her shoulder. "This is serious!"

"Okay-yay-yay! Wow, you… are mean in the morning!" Swatting at Anna's arm, she began sitting up. "It's just that… I tried to tell you, I think. Sometimes they go away. And they're never out during the day; I mean, I don't think they can be. But some nights they don't show up, either. So… yeah, gone right now."

Blinking at her, Anna finally found her voice. "B-but that makes no sense! How can they be there one minute, and then…" She shrugged when she finally heard herself. "Then again, how can you have invisible tentacles in the first place? Yeah… yeah, nevermind."

"Sorry," Elsa chuckled groggily. "But, um… I was honestly hoping we'd never have this conversation, so I'm a little lost for words right now."

"That's alright," Anna sighed as her adrenaline finally began to fade, and she plopped back down next to her. "I'm just glad you're… I mean, okay? Do they hurt when they come out, or anything?"

"Not at all. I just… wake up in the middle of the night sometimes to find I can feel more things than usual… brushing over the floor, sometimes climbing up to the ceiling or against picture frames. Until I was maybe nine or so, I always thought it was a dream. A recurring dream that I couldn't get rid of, but eventually… I mean, you start to wonder, right?"

"Yeah, I guess I would." Again, she passed her hand up into Elsa's armpit, feeling the smooth skin there. Not even a scar, nothing. "Wow…"

Giggling, Elsa raised both arms over her head. "Explore all you want. I mean, unless… do you have a thing, maybe? No judgment if you do..."

"Huh? What thing?" But then she noticed how she was massaging the armpit and dropped her hand. "Oh, gross, you weirdo!" The instant Elsa's face fell, she realised her mistake and leaned forward to kiss her cheek. "You're not a weirdo. Shit, I'm sorry I said that, I didn't mean it that way."

"Yeah… yeah, I know you didn't, it's okay." Taking a deep breath, Elsa let it out slowly, then smiled up at her. "Sorry for reacting. Just, when you have extra appendages sometimes, you start to get really worried that someday… people will find out, and you'll be sent away to a government facility or something."

For just a second, Anna looked intensely serious. "I will… never let that happen, Sis. Ever." Neither of them knew what to say to that. Eventually, she wrapped her arms around Elsa's shoulders and dragged her back down to lay next to her. "Oh man, I can't believe we get to do this again, after so many years!"

"Well, I told you why we couldn't. My body was… turning into something I couldn't control. And I didn't want you getting in its line of fire." Then she sighed and rolled her eyes. "If I'd known you wanted to be in its line of fire…"

"Oh yeah? What about you?!" Her smile turned quite smug. "Having the hots for me for years and not saying a damn thing…"

Blushing, Elsa frowned at her. "Honestly, Anna, how was I supposed to tell my own sister that part of my body-"

"More than one part of your body."

A heavy glare accompanied the rest of her words. "That parts of my body were after hers? That's… not normal, even if I was just a normal human. I didn't want you to think I was just some sicko who didn't care about you."

Pushing her lips up and against Elsa's, Anna tangled their legs anew, petting along her neck in comfort. She didn't know how to say that she could never think that about her sister without sounding sincere enough that she'd believe it, so she didn't try. After a few seconds, she snorted and instead offered, "Your feet are cold."

"Doesn't bother me. Does… it bother you?"

"Why would it? Just making an observation." Then she glanced at the door. "You know… this is vacation. I don't think they'll miss us if we take another, oh… ten, twenty minutes to come out of this room?"

Rolling her eyes, Elsa immediately got up and went to her dresser to begin grabbing her clothes for the day. "What a pig."

"Fine, fine. Can we take a shower together?" The way Elsa dropped her special bottle of conditioner was enough to send Anna into a gigglefit.

~ o ~

Their last day among extended family was a nightmare for Elsa, but a dream come true for Anna. The little sister was insatiable, dragging her behind every corner in a store or in the house for a stolen kiss, or more. At first, Elsa resisted, afraid they would blame her for being the elder sibling and not "protecting" Anna from such an unconventional relationship, but Anna was so persistent and adorable that eventually, she began to look forward to the game as much as she. Anna was very satisfied with that result.

Much, much worse was the hot springs. Anna was merciless, even if Elsa obviously did enjoy what her teasing hands were doing under the water - if the shivers and groans were any indication. When her mother came and joined them, sitting more or less between them so they couldn't be as close as they were before, Anna's teasing toes still managed to find their way to her thighs. Elsa's bright red face said that she needed to stop, and she did… eventually.

Later that night, Anna waited for the ghostly appendages to come for her, even long after Elsa fell asleep. No such luck; the room remained quiet, peaceful. At some point, she reached over to pat under her half-sister's arm to make sure, and found nothing. After an hour or so, she drifted off herself, a tad disappointed but not terribly so. They were fun, but not essential.

The next morning, on their way out of the house, Hokusai-ojisan stopped them and told their parents he had a gift for the two sisters. Once their parents nodded and went outside to the rental car, he turned back to them with a very serious look on his face.

"Elsa is oni. There is no use denying it or talking about it at length; telling you I know should help this conversation move faster."

The girls glanced at each other. "Oni?" Elsa finally asked for both of them.

"A demon. Shokushu-oni." After waiting a significant amount of time for one of them to answer, he finally sighed in disgust at their stubbornness and announced, "I saw you on your way to use the toilet the night before last."

Now Elsa looked horrified. "Oh… oh no, I d-didn't- I thought by then, everyone would be asleep, they w-wouldn't see! What- I mean, are you going t-to-"

"Grandpa-ojisan, please!" Anna pleaded, remembering at the last second that she was supposed to bow really low when asking him a favour like this. "Just… just don't do anything to hurt Elsa! I love her!"

"Oh, of course you do," he harrumphed. "The type of 'love' you have for her was written all over your face yesterday; that glow in your cheeks, all those giggles! Do you think I am blind because I am old?!"

That was an even bigger shoe to drop. Both girls began to blush to their ears, ashamed that it had taken a mere twenty-four hours for their "big secrets" to be burst wide open by an old white-haired man.

"I won't tell your parents," he sighed, though his voice made it clear that he did not exactly approve. "However, I did not lie to them; I do have gifts for you."

He offered both of them a thin wooden box, painted black with red kanji emblazoned across the lids. Elsa was still glancing between it and the old man when Anna opened hers, wondering why he was bothering to give them gifts right after he essentially called them a monster and a degenerate.

"Ooh, it's beautiful!" Holding up the fine silver chain, she revealed a greenish stone with a diamond-shaped hole in the middle, also bearing characters she didn't know how to read. "But what is it, a necklace?"

"A talisman, of sorts." When they turned their attention to him, he said, "With this, you will be able to see as I saw that night; the invisible things of this world cannot hide when viewed through that jade."

The hole in the middle suddenly made more sense. Anna aimed it at Elsa, and saw what seemed like nothing but a hazy light near her shoulders. "I… can't see much right now, but then again it's daytime. You… I mean, is it really okay if I keep this?"

"You have more need of it than I." His open palm gestured to ward Elsa. "Go on."

When the blonde lifted her own lid, curious, her expression darkened. Glancing at Anna with her mouth a taut, straight line, she lifted a small knife from inside. The sheath and handle were made of ivory, but it was darkened from years and years of age.

"And… am I supposed to take my own life with this?" No answer. "Wow. Thank you so much, Ojisan."

"You are no granddaughter of mine," he said in an even, unconcerned tone. "But what you do with that knife is up to you. I will only tell you that it has been blessed so that it can affect things that are… not merely mortal."

"Wait," Anna interrupted. "Are you telling her to… cut off her thingies?! That's horrible!"

"It may be necessary," he told her in a grave tone. "Of course, if you wish to preserve Elsa as she is now, that is your choice - but be warned that her power may manifest in other ways in the future. And they might not be as… fruitful as the ways they have thus far."

The expression was more taut than ever as Elsa stared down the old man. "Anna has nothing to fear from me. She is all that matters to me in this world."

"Perhaps."

They were still gaping at him, trying to figure out if he was making sense or raving, when their parents came back in. All of his seriousness evaporated into a warm smile as he bade his daughter and her husband a safe journey. He did hug Elsa, despite the cold and sudden declaration moments before that she did not count as his family - but when he hugged Anna, he whispered, "Be careful, my aka ari."

"You don't have to worry," she told him with steel in her voice. "Elsa loves me."

"She does. But that may not be enough."

And with that ominous parting, they left the house their mother once called home. It would be many years before they saw it again.

~ o ~

Once at the hotel, their parents were ecstatic to find out Anna and Elsa no longer minded sharing a room, despite Elsa's complaints and Anna's shyness around her from many days before. Self-satisfied that making the sisters bond during the daytime had been what made the difference, they reminded Elsa to take her medicine and returned to their own room. Apparently, they were satisfied that Elsa could control herself now that she had grown up a bit.

Some nights, nothing happened - both in a supernatural and a carnal sense. Other nights…

Anna would feel something slither up over her thigh from Elsa's side of the bed, and she would grab the stone that hung around her neck, holding it up. Sure enough, with the half-light from the window being bent through the opening… she could see the ghostly tendrils she'd spotted before when she first woke up. Sometimes they seemed grey, but other times an icy blue. She wondered why she could see them on her own that time but never again after that. The thing Elsa had mentioned about other people who are "like her" being able to look at them worried her slightly, but there was no other proof that she was similarly gifted. It must have just been a fluke.

Then she would direct the tip of it toward her underwear as she tucked the stone away beneath her pyjamas. Even if Elsa was already asleep, her subconscious was not yet satisfied. Anna was only too happy to oblige.
