In just a few hours, Anna figured out the basics of moving her new anatomy. A set of four tentacles that extended seemingly as far as Anna wanted them to.

After a couple of days, Anna had for the most part mastered their movements, avoiding the basic pitfalls such as tangling them together, or losing her balance. The tentacles themselves didn't seem to weigh much of anything, but anything she lifted with them did.

Over the next couple of weeks, learning some of the more advanced tricks was next. It took more concentration than Anna liked to mould each tentacle into a different shape or size, but that was a trick she simply needed to have under her belt. She would have to ask Elsa to help her understand some of the other things she experienced that fateful night. It took Anna the rest of the month just to work up the courage to subject her elder sister to some of the less conventional acts she witnessed. Especially the spanking.

So it was yet another surprise when a fifth "player" decided to join. The whole thing was sudden, starting as another small growth reaching around her back. With some intense thought, and a lot of saved up energy, Anna grew it into a full fledged tendril with remarkable ease. Anna had gotten home quite a bit earlier than her sister, and became excited to show off her new addition.

Perhaps a little too excited. Elsa gently pushed the tentacles back as she got up to her feet. "Let's not rush this, Anna. We have all night to enjoy each other." She slowly walked right up to Anna, tentacles still gliding around her body.

"Right. I'm sorry, Elsa. They always just-" it wasn't just that, the recent news gave Anna a dreadful sense of looming deadlines. Like this slice of bliss in her life was on notice.

"It's not just them, is it?" Elsa asked. Sisterly instincts were still a thing, despite their virtual separation. "I'm not going anywhere, Anna. Not without you. Things will still be fine for us after the move. Think of it as me working hard to make all these moments possible. That can only make them more special."

Anna nodded. "I'm sorry, Elsa. You know me. I'll probably have to be told a few more times after this."

"After everything I put you through, I think you're worth more than a little patience." Elsa walked up and gave Anna a small peck. Then another kiss. One more. For a moment, it looked like it might blossom into a full make-out. Maybe next time.

"So," Anna whispered. "How would you like to spend this time?"

Elsa gave a suggestive giggle. "Well, I never said we should do something else. Only that we should do this at the right pace. Let's see if you have any new tricks."

"Well, there's nothing we can do just yet. Buuuut-" The first tentacle stopped its aimless meander around Elsa's body and moved in on the front of her shirt. Slipping along each button on the way up, pushing it off with gentle ease. Unveiling Elsa's smooth, slender body always gave Anna a small rush of excitement, and now she was better at it than ever. With a soft caress of Elsa's cheek, the tentacle tugged the collar, allowing the shirt to slide off Elsa's arms.

"That's a lot more fun when you do it." Elsa squeaked as another tendril tickled her torso. "Woah, easy there." She reached over, running a hand along Anna's side. "I won't let you have all the fun."

Elsa's hands were every bit as soft and comforting as they looked. Every bit as exciting as Anna imagined. Perhaps greater. Especially after that unforgettable night left her rather unsatisfied. Sure, there were more important things to worry about, but at least physically she was left with a poor aftertaste. That could be why Elsa worked so hard every one of their special nights afterwards. That, and the now five advantages that Anna possessed.

The next thing Anna knew, her legs were up against the side of her bed. A good a place as any to continue. "So, you think you're ready now?"

Elsa licked her lips. "Hold on, not when I'm still-" while Elsa wasn't looking, one tentacle managed to slip her skirt open, letting it fall like the shirt did. Leaving nothing but Elsa's underwear.

"How's that?" Anna asked, with a ghost of a smile. "Comfortable enough for you?"

"Plenty." With Elsa's formal wear gone, she seemed to relax. With Anna sat on her bed, Elsa lowered her head down into Anna's lap. Making Anna feel no less special than any other time. Elsa didn't seem to want it nearly as much; it seemed Anna's extensions were more than enough for her. To be fair, there was plenty they do on their own. It just felt a bit like she was cheating.

The only reasonable thing she could do was share her strange gift with her sister. After removing her last clothing, the tentacles moved around Elsa, four of them working to tease and excite the body it lavished. The last moved around to the back of Elsa's head. Holding her irresistible lips, her soft tongue just close enough.

Every touch somehow turned out more exciting, more tantalising than the last. Not just tonight, but over every precious night they spent together. Anna wasn't exactly finicky, but Elsa always managed to hit the good spots. Each tender kiss between her folds, each gentle slide of her tongue sent warmth and excitement to the very ends of her body. Elsa had a way of going above and beyond even Anna's imagination.

As a result, it became that much more difficult for Anna to focus on what she was doing with her extra limbs. Like learning to walk again, they more or less moved back and forth without her thinking now, but to make precise movements like the ones she was attempting around Elsa's bra strap took a lot more focus. Especially when she couldn't see, and Elsa was driving her pleasure ever higher. More focus than she could muster. Elsa finally held her tongue, allowing Anna the coordination she needed.

"Next time. I'll get it next time," Anna said, panting softly.

"That's the fourth time you've said that." Elsa couldn't help give a sly smile up to her sister. "Don't let your mouth write checks your extra limbs can't cash."

"Oh, shut up!" Anna huffed. "Or don't you want my friends to me cashing anything for you tonight?"

"Woah woah," Elsa cut in, loosing her bra completely. "You're still learning. Why don't you try something you're good at already? I know there's plenty."

Anna gave Elsa a suggestive laugh, as a couple of her tentacles slipped past the laces of Elsa's panties. "Oh, you would know all about that, wouldn't you?"

"Oooh! You're certainly excited today," Elsa squeaked. Anna had found her mark, and Elsa was already starting to quiver. "Is there something- urh- else you'd like to do?"

You read my mind. Or at least, half of it. While Anna did have something more full on ready to go, she wanted to try something even riskier to get them there. "I think we're ready to move on, yes. So if you just hold still for a moment."

"Anna, what are you- woah!" In just a few seconds, Anna managed to wrap her tentacles around her sister and hoist her up to eye-level. More noticeably, breast to breast. The trick, it seemed, was to do it all at once instead of hesitating. "You are improving." They shared a kiss slightly longer than the last. More tender. More fulfilling.

"You know it," Anna whispered. "How about we get to the main event? I know you've been waiting." Anna retracted each of her tentacles. The time for teases was over.

"Not yet." Now free of Anna's extra limbs, Elsa shuffled around to face the same direction, leaving her back pressed against her younger sister. "There." Not the best view, but a good chance to show off her skills even where Anna couldn't see.

Anna ran the tentacles under her own legs to greet Elsa. Only Elsa greeted one first, putting a gentle grip on it with her hand. Guiding it in the right direction. Sliding it along her moist lower lips one more time for good measure. With a little more force from Anna, she let it gently inside, allowing it to take her once more. The wave of pleasure reverberated through Anna's body, making her skin tingle and giving that craved sense of bliss. How in the world could any of this be wrong?

In fact, the pleasure was far too great to let Elsa enjoy all to herself. Anna had quietly gotten a second tendril to give herself the same experience as Elsa. Yet another thing she wished she had gotten over the discomfort of trying a little sooner. As Elsa rocked her hips up and down her occupant, Anna did her best to match her sister's pace back and forth inside herself. She could always adjust later if one of them started to lag behind. In the meantime, there were plenty of ways to make this more interesting. More intense. There were three tentacles left to direct, but that didn't mean she couldn't enjoy things the old-fashioned way.

While a thin third tentacle wrapped itself around Elsa's left breast, Anna's left hand found its way around the other. Driving Elsa's pace and her elated moans ever higher. Anna could do better, though. With a little more difficulty, her right hand homed in on Elsa's sweet spot, just above the main action.

"Haaah!" Elsa cried. She definitely felt that one, though it wasn't hard for Anna to tell. "Anna- Anna," she panted. "More, I want more. Feed me."

Hardly a subtle hint for what she wanted. For the life of her, Anna could never quite figure out how to copy the strange trick that creature did. Giving a perfect copy of a taste or smell. It certainly wasn't from a lack of trying, mostly because Anna though it would be amazing to do that. For now, plain tentacle would have to suffice. So up it went, crawling along Elsa's body, receiving a welcoming lick as it slid into Elsa's mouth.

As their shared pleasure rose ever further, keeping movements in sync became more difficult. Not that Elsa seemed to mind. Both of them moved faster and faster, moaned higher and louder, though Elsa's moans were now muffled. It wasn't quite the use of Anna's new limb that she hoped for, but that didn't matter. Elsa was having the time of her life, as Anna would know. More, more, more. That's all she wanted now. For both of them.

"Mmmmmph!" Elsa managed, going over the edge. So close together, their shared heat reached a fever. A sublime haze. Elsa's climax was more than enough to push Anna to her own peak, giving them almost perfect synchronisation. It was tempting to fall back on the bed in an elated exhaustion, but Anna didn't want to upset this moment. Especially with that ping of doubt Anna still felt about how often they could enjoy this in the future.

It may have been a whole minute, but Anna finally noticed her sister wasn't quite so content to sit idle. In fact, As the tentacles slipped away, Elsa was back on her feet. With a soft, yet confident hand, she shoved Anna back onto the bed.

Elsa hopped forward, leaning in next to Anna. "Not bad, for a warmup." She caressed one of the tentacles swinging above Anna, bringing back a spark of vigor to her body. "But you have five, don't you? It's time to see what you can do. Test the limits."

Anna froze. She forgot just how into this her older sister could get. "Uh, test what limits, exactly?"

"I'm talking-" Elsa leaned in close. "About going all in," she whispered.

"All in?" Elsa's sultry look was met with one of confusion. "You've done all of that already."

"Oh?" Elsa laughed softly. "I'm not just talking about me this time."

Anna paled. "Wait, What?" She was more than happy to let Elsa indulge her desires to her heart's content, there were certain things Anna didn't think herself quite ready for. "Elsa, I dunno. I mean, I'd like to, but, you know, when I'm ready?"

"If not now, then when?" Elsa wasn't going to give up on this, was she? Even if she flatly refused, Elsa would simply ask again later. Anna was certainly open to the possibility, but there was no way she could match Elsa's first time, not while she hadn't learned all the same tricks.

"I- what if I don't like it? What if it's too much for me? What if I- like, really hurt myself? What if it causes me to-"

The next thing Anna knew, Elsa was right on top of her, holding a finger on Anna's soft lips. "It'll be alright. Just start small, alright? It might be a bit uncomfortable at first. If anything feels seriously wrong, just back out, alright?"

With her limited space and continuous jitters, Anna managed an uneasy nod. Why couldn't she muster up the courage to see this through? If Elsa could do this, so could she. "Okay, I'll try."

Another short kiss. "Just try not to worry too much. Relax as much as possible. Being more tense won't help you at all." Easier said than done. Strangely, the worst thing about this was Anna was doing this to herself. With all focus, she took the narrowest of her tentacles and lined it up. Perfectly positioned. Elsa was still. Just waiting. Here goes.

Please don't hurt too much. Anna started to apply pressure, getting her own undivided attention. There was definitely a hint of discomfort. Please, don't hurt. As the feelings clashed with each other, Anna tried to follow her sister's advice. She was still opening up. The feeling was slightly worse than before, yet she genuinely want to continue now. Please, don't-.

"Aaaaah!" Anna cried out. She couldn't see, but there was no doubt. She'd made it. Anna couldn't move again just yet. Her mind was a burning haze, leaving her with little coordination.

"My, my," Elsa said, looking back. "You did well there. By the looks of things-" Elsa reached back to the point of entry. "Oooh, looks like you managed to lubricate yourself. I didn't realise you could do that now."

"But- I couldn't. Or at least, I- I thought I couldn't." There wasn't a lot Anna could think about. Only that she didn't want this to hurt. "Wait, maybe because I wanted it badly enough."

"Well, they did run on emotions and desires before, remember? You just have to want something strongly enough." Elsa stretched her left hand over her hind. "Speaking of which, there's something I want rather heavily right now."

It was almost scary how different Elsa became during their intimate moments. In just a couple of minutes, her calm self shattered and her inner desires came out in force. That was the power of that creature. Anna's power now. After all the time apart, she wouldn't miss these moments for the world. Not because it made Elsa happy, or Anna, but because they could share this.

With enough focus back, Anna managed to engage her extra limbs. In a few intense, yet satisfying seconds, the tentacles converged on the sister's joined rears, making the fun four for four. Anna bit into her lip, to which Elsa simply breathed a sigh. Her contented smile made it clear she lived for this, even if it was nothing new. For Anna, this was still a raging mix excitement and nervousness. Especially as she started to move all of them, almost entirely on instinct. There was no way she could move them on their own like that; not in her current state of mind.

Four. Four sources of intoxicating pleasure all feeding directly to her. On top of that (and Anna), her sister's silky, warm skin rubbing against her, making her feel each movement that much more. Elsa let out the occasional moan every few seconds, each a little higher pitched than the last. The only thing Anna could let out was the occasional tear from her eyes. There was no way this could stop. Not now. Not ever. There was still more that could be done.

One more tentacle. She still had one more she could use. How, though? The last thing Anna wanted was to create an unfair situation between the two of them when things were going so well. Could she pull off one last trick?

Focus. Same as before: create the desire, and let that fill your mind. Even with everything that's was already filling her. Focus. All the simpler good times that Anna and Elsa shared. Once a distant memory, now made anew with each day. Focus.

That divine taste-

There. The last tentacle gave off a sticky looking liquid. Could it be? Had she done it-

Yes! Vanilla fudge. Her favourite. "Elsa-" she gasped between thrusts. Offering the last, sticky tentacle between the two of them.

Elsa seemed to pick up on it immediately. At first, they took it in turns. Taking, long, slow, deep licks. Then, together. Tongues occasionally running into each other. Giving Anna her cue to produce more of the delicious syrup. Almost as sweet as her sister's satisfaction. For a short moment, enough to make Anna forget about the worries she felt about the times ahead.

As long as there was a way to spend more quality time together, it wouldn't matter how long it took. Not because of the relief after waiting, but because of Elsa herself. She had worked so hard to make all of this possible. It was up to Anna to work just as hard.
