Chapter Text
Anna glanced around to check that the hallway was empty, but nobody was around to notice as she let herself into Elsa’s room. They’d been favoring Anna’s room for a while, so she figured fair was fair. Elsa’s new room was cozy anyway. Anna shut the door behind her and smiled over at Elsa, who was sitting on the bed. “Hey, Sis.”
Her sister glanced up from her book. “Oh, hello, Anna.” She smiled gently, but Anna could see Elsa’s eyes flicker down to see if she was carrying anything. If Anna brought books or chocolates, that generally meant that they would just hang out and chill together for the evening before going to sleep.
Anna grinned at Elsa and waved, highlighting her empty hand. Then she reached her other hand behind her back and locked the door with an audible click.
“Oh.” Elsa blinked. Her smile widened and Anna noticed her sister’s hips shift.
Anna winked and sauntered over. “The lock, if you would, Elsa?”
Her sister nodded and flicked a hand. Behind her, Anna heard the now-familiar clink of ice sealing the lock with extra protection.
The sound sent a shiver up her spine. She’s begun to strongly associate it with certain activities; they didn’t need extra security on the door when they were just reading or chatting. And while she hadn’t initiated a lesson since the last time, when she’d helped Elsa to include her powers, Anna had certainly been satisfying herself in private. Her hips tightened as she walked toward the bed with the sound of the ice clicking into the lock behind her. Attending to her needs in private was fine, but she found herself caught in yearning lately, eager to return to the shared sessions in which she and Elsa engaged in the company of one another.
But, as the teacher, it was her job to attempt to refrain from letting her own desires get in the way of guiding her sister to feel comfortable with her own body and to find pleasure with herself. That was the point of this, after all.
Anna smirked, stopping at the foot of the bed to lean a bit closer and wink. “Are you ready for another lesson?”
And Anna had needs, desperate aching cravings she wasn’t sure that she could fulfill by herself, but... seeing the way Elsa’s eyes widened, how her sister’s mouth opened, but how Elsa didn’t say anything until she licked her lips and stammered a, “Y-yes, Anna.” Seeing how her sister anticipated Anna’s lesson was more than enough motivation for Anna to put aside her desires.
Elsa came first, always. The thought’s double meaning, and how Anna made it true every lesson in more ways than one, almost made her snicker. She took a breath and repressed the urge.
“Perfect,” Anna said, trying to capture Elsa’s effortless hip sway as she walked around the bed and over to her usual side. “So, I know I never properly assigned you work to do outside of our lessons, but I’m assuming you’ve done some practice?”
Elsa nodded, running a hand through her hair as Anna clambered onto the bed. “Yes... I, ah, waited a day or two after our last lesson. Didn’t exactly feel quite as, ahem, needy.” Anna grinned as Elsa bit her lip before continuing, “but the urge to practice eventually spurred me to do so.” An almost sly smile crossed Elsa’s lips. “I may have also done some, ahem, experimentation.”
“Hmmmm. Experimentation?” Anna felt conscious of the urge to grind her hips down as she settled herself in a comfortable sitting position beside Elsa. She resisted the impulse to sit on her heel and rock on it, to give herself something firm to press herself against, but only just. Instead, she sat cross-legged and leaned back against the headboard. So casual, just what she was going for.
“It sounds as though you’re being a very proactive student.” Anna turned toward Elsa, who had closed her book and was fiddling with it in her lap. Anna didn’t even try to suppress her smirk. She looked right into Elsa’s eyes as she said, “Good girl.”
The phrase made her sister’s shoulders hitch as she caught her breath. Her hips shifted forward and Anna’s smile just grew wider as she watched Elsa try and grind down on the bed for a moment before she caught herself.
“You know,” Anna said, leaning to the side so her head was against Elsa’s shoulder, “I never quite intended for you to get such a strong association with the phrase. But I’m rather fond of the effect.” She batted her eyelashes playfully at Elsa, who huffed and quickly looked away.
Elsa’s shoulder made a half-hearted nudge to throw Anna off. “There’s hardly an effect.” Elsa’s voice was slightly grumpy and a bit too high to be truthful.
“Sure there isn’t.” Anna angled her face so she could see Elsa’s better. “I’m curious about something though. Does the phrase incite arousal on its own, or just augment your existing inclinations? You know, work on what you’ve already got going on?” Her sister had crossed her arms and was looking away, but Anna could still see a pair of tell-tale bumps standing out under her nightgown.
Elsa huffed, cheeks pink. “Both? I can’t really tell or differentiate well enough to give you a clear answer, I’m afraid.”
“That’s fine, that’s fine.” Anna hummed smugly to herself for a moment.
Elsa cleared her throat. “But yes,” she said, “I have been, ahem, practicing. Experimenting.”
Anna’s hips clenched as her imagination began to whirl, tossing out haphazard ideas and scenarios of what exactly her sister might have been doing with those powers and her nimble, nimble fingers. The previous lesson plan had required Anna to mull over just what was possible with Elsa’s magic and what would be good or comfortable for her to start out with. And her brainstorming had paid off in Elsa’s strong positive reaction to the lesson, but Anna had, perhaps, found a bit of personal pleasure in the process of brainstorming the lesson plan to begin with.
The idea of Elsa basically doing the same thing, thinking of ways to be creative with her magic, and then applying the ideas and pleasuring herself on her own made Anna feel warm and tensed her muscles. That Elsa had done so based on Anna’s own suggestions, maybe even thought about Anna while she touched herself, alone in this very bed—
“Um.” Elsa nudged Anna’s head with her shoulder.
Anna pulled back and straightened up immediately. “Whoa, sorry. Just zoned out there for a moment.”
Elsa rolled her eyes. “It’s fine.”
They sat in silence for a long moment. Despite her best efforts, Anna felt her shoulders hunching slightly in self-consciousness. Elsa had mentioned that Anna could maybe “have some of the fun” with ice powers in their next lesson. But Elsa had also been borderline high and half-asleep at the time and Anna would be a jerk to take her sister’s statement as full confirmation of that happening.
“Well you know me,” Anna said, plucking a smile to her lips. “I’m always off in the clouds a bit.” She sat forward. She was here to make Elsa happy. “But you said something about experimentation. I’m curious about what you’ve been up to.” She winked before continuing, “So how about you give me a demonstration.”
Elsa’s cheeks colored, but her expression didn’t shift away from coy interest. “A d-demonstration?” if anything, her smile grew wider, more anticipatory.
Anna shifted so she was facing Elsa, leaning her shoulder against the headboard. “Sure,” she said. “I’m interested to see what sort of innovations you’ve come up with.”
“Just to see?” Elsa’s cheeks seemed to have turned a deeper shade of red. “Well then, I hope to, uh, impress?”
As her sister shrugged and smiled, slightly awkward, Anna couldn’t help but grin back. She would always remain steadfast and loyal to the formal, pristine Queen of Arendelle, but her favorite Elsa was the dork who covered her mouth when she laughed and woke up with tangles in her hair. The woman whose back arched when she came, learning to love her body that deserved that and more.
“Elsa,” she said, “you always impress me.”
Her sister rolled her eyes, but Anna noticed Elsa’s smile widen as she shook her head. “You’re such a flatterer, Anna.” Elsa scooted off the bed. “Would you mind grabbing the spare blanket and laying it over the bed? You know how melting ice is.”
“Not a problem!” Anna hopped off the bed on the other side and fetched a thick blanket from a nearby basket. Turning around to cover the bed, she was treated to the sight of Elsa pulling her nightgown over her head, having already discarded her underwear.
Hit with a sudden urge to touch herself, Anna reminded herself that it wasn’t because of some inherent quality of her sister’s curves. It wasn’t because of Elsa’s hips or the arc her neck made as she leaned forward to fold her nightgown. It wasn’t exactly related to the way Elsa’s unbraided hair tumbled down over her shoulders in waves that covered her breasts in a gesture toward modesty that ultimately only made the whole image more enticing.
It wasn’t any of that, really. Anna just had an association between her sister being naked and, well, masturbation. Which usually meant arousal and orgasms and those were just nice things that tended to follow seeing Elsa naked.
And that was just fine. Anna smiled to herself as she spread the blanket out. They weren’t typical sisters.
Once the blanket was in place, she leapt onto the bed and sprawled out in the middle, arms and legs splayed wide. She grinned upside down at Elsa, who’d been just about to get onto the bed. “Hello there,” Anna said with a wink.
Her sister crossed her arms. “You’re such a dork. Do you want your show or not, because there’s no room for me with you spread out like that.”
There would be room if Elsa just did her show on top of Anna, kneeling over her hips as she touched herself, fingers and ice all—
“I’d be greatly remiss to keep you from your demonstration.” Anna giggled and rolled back onto her usual side of Elsa’s bed, propping her head on an elbow as she lay on her side. “I hear the queen can be a bit of a show-off with her powers. Making ice rinks and giant snowflakes in the sky and all.” She wiggled her eyebrows. “Is there anything like that in store for tonight?”
Elsa snorted in an unlady-like fashion that belied her appearance. Even stark naked, Elsa looked regal. “Nothing quite so ostentatious, I assure you.” Elsa resumed her place sitting with her back against the headboard. “And I don’t think either of those two examples would work well in this setting anyway.”
“Maybe not, maybe not.” Anna stuck her tongue out. They gazed at one another for a long moment before Anna jumped into a sitting position. “Oh, wait,” she added, “Would you like for me to strip too? I know you’re generally more comfortable if we’re both naked.”
Elsa smiled sweetly and nudged her foot against Anna’s knee. “By this point, I think I’d be comfortable even if you didn’t, actually.” Then a faint blush tinged Elsa’s cheeks. “But... if it’s not odd, I would like you to be nude as well.”
Anna rolled her eyes. “That’s hardly odd between us, Elsa.” She pulled her nightgown over her head. Without thinking, she added, “I like when you’re naked.”
Almost immediately, Anna wished she could take it back. Surely that was too forward. She finished pulling her nightgown off and trained her gaze on her sister’s face.
No disapproval, no awkwardness. Elsa actually looked flattered, somewhat. “Well that makes two of us, I suppose.”
They smiled at one another for a moment before Elsa gave Anna’s knee another light kick. “Don’t forget your underwear, dork.”
Anna rolled her eyes as she shifted to slip them off. “You have a lovely bedroom manner, Elsa.” She tossed the garment onto the floor with the nightgown. “Just pristine. You’re the sweetest.”
She was about to lie back down when Elsa leaned forward and grabbed her shoulder. She quickly pressed a kiss to Anna’s cheek, then let go and sat back.
Though Elsa’s lips were cool, Anna’s cheeks felt warm. She tucked some hair behind her ear and smiled. “Yes, I know you’re actually sweet. But I believe you were going to give me a bit of a demonstration?”
Elsa nodded slipped a hand between her legs, then paused for a second as a new flush swept across her cheeks. “Actually,” she said, “may I ask you a favor, Anna?”
“Anything.” Anna tilted her head. “What is it?”
Tilting her knees together and reaching a hand back to rub the back of her head, Elsa cleared her throat. “Well, uhm, if it’s okay, would you mind, maybe, touching yourself as well?”
Anna quickly compared in her mind whether it was more or less strange for her to watch Elsa touch herself or for them to touch themselves together. Neither prospect was undesirable, but, admittedly, based on their last month or so of mutual masturbation and Anna’s lessons, the latter felt more normal. If Elsa was having fun, why shouldn’t Anna get to do so as well?
“I don’t think it’s a problem at all,” she said. “Definitely less awkward I guess, if only out of habit.” Anna hadn’t even considered saying no, but it felt easier to justify her answer.
That and Anna had maybe kinda sorta been wondering whether or not it would be okay to touch herself anyway, given that Elsa hadn’t even started and she was ridiculously turned on already. She felt her cheeks warm as she realized that, certainly, she’d given Elsa plenty of orders and instructions on the matter of masturbation, but this would be the first request Elsa had given her. The thought was... enticing.
But then Elsa frowned. “That too, I suppose. I suppose it’s what we’re more used to but...” Her blush deepened. “I guess I was asking if you didn’t mind touching yourself because... I want you to?” Anna noticed Elsa’s cheeks reach a new level of red before she buried them in her hands. “Okay just forget I said that,” Elsa mumbled into her hands. “I don’t know why I thought that was okay, I just had a thought and I thought it wouldn’t be too strange to ask but then I said it aloud and wow that was not okay to ask.”
“Hey, hey. It’s really fine, Elsa.” Anna pushed herself up onto her knees and crawled over to her sister, who had begun to hug her knees to her chest with her face buried in her arms. “It’s really okay. I was just thinking that I actually wanted to be able to touch myself while you were, but I wasn’t sure how to say it.”
“Truly?” Elsa spread her fingers and peeked out from between them. Despite her anxiety, she looked adorable.
Anna grinned and rubbed the back of her head. “Really truly totally, yeah.” She tried to make her smile reassuring, but got the sense it only became more awkward. “Watching you get yourself off... it’s arousing, honestly.”
Elsa’s eyes widened (and not in a bad way either, Anna noted), but Anna felt too embarrassed to maintain eye contact and looked away. “So there.” She turned and sat next to Elsa with her back against the headboard. “Now we’ve both said not-okay things. Was my not-okay thing actually okay?”
Anna almost jumped when Elsa reached out and put a hand on her knee. That’s what she got for staring at the ceiling. “It’s fine,” Elsa said. “I feel similarly to you.”
They sat in a comfortable silence for a long moment. Well, comfortable and actually more aroused than before, at least on Anna’s end. She wasn’t sure about Elsa, but from how her sister shifted her hips, Anna could probably guess.
“And our feelings on this are okay?” Elsa asked.
“Nothing is strange with you,” Anna asserted, bumping her shoulder against Elsa’s. “Though if you never get this show of yours started, I’m going to do one of my own just so we can get going already.”
She watched Elsa’s expression shift from hesitation to something almost wanton. A shiver rolled up Elsa’s spine and her eyes flickered down over Anna’s body for a moment before she looked away. “So impatient,” she muttered with mock offence. But Anna noticed how her sister’s voice wavered, how it caught in odd places.
She liked how it did that.
Elsa leaned back against the headboard and spread her legs with her knees slightly bent. “This... might seem strange,” Elsa cautioned. “I’ve been doing some experimentation and found that, um, without your presence, without your orders, I have a lot of trouble staying still. Especially as I come closer to orgasm.”
A smile twitched at Anna’s lips. “The queen, lacking self control? The nobles will be scandalized.”
“I think they’d be quite scandalized before you even got to explaining that part,” Elsa commented dryly. “In any case, I was enjoying myself a bit too much, so I decided to try out a few solutions to maybe help me stay still. At first it was just to help achieve that goal, but then I found the practice to be... arousing of its own accord?” She cleared her throat. “I’m not sure if is unusual though. To, um, tie myself up, just a bit, essentially?” Elsa looked at the ceiling awkwardly.
“Restraint while touching yourself?” Anna elbowed her sister to get Elsa to look at her, then smiled. “It’s actually something I enjoy sometimes, though I get the feeling my bedsheet-ropes are a bit less elegant than your magical solution.” She shrugged. “I would have brought it up sooner in some other lesson, but after your experience being locked in the dungeon, I didn’t want to try anything potentially stressful.” That and it felt different on some level, to have Elsa tied up as part of a lesson. Anna hadn’t wanted to suggest anything unintentionally taboo.
This time, Elsa shook her head. “I might have been a bit anxious if you’d brought it up first, but coming to it on my own, I don’t feel negatively about the restraint at all.” Anna’s eyebrows raised as Elsa waved a hand, generating a spiral of frost near her ankles. “I found something that feels good to me,” Elsa continued, “and it’s... empowering?” The magic materialized into a pair of silken cuffs, linked to one another by a length of taut icey fabric similar to Elsa’s dress. With another hand-wave, a pair of twisted, icey silks seamlessly attached themselves to the pieces around Elsa’s ankles, then to the bedframe behind her. The conjurations fixed themselves in place, holding Elsa’s legs in place and spread apart.
“No fiddling around with knots for you?” Anna asked, brushing her fingertips along the piece between them. It was cool and fine, but felt quite strong
Elsa smiled a bit self-consciously. “When the idea first occurred to me, I was feeling, shall we say, pressed for a timely solution.” She pushed against them for a moment before frowning and waving her hand again. Immediately, the leads securing her ankles to the bed shortened, spreading Elsa’s legs wider apart. “Okay,” Elsa murmured, more to herself than to Anna. “That’s better.”
Elsa turned her attention back to Anna. “Ready?”
Something about the slight flush of her sister’s cheeks sent a tingle of awareness to her clit. “Y-yeah,” Anna said, tensing the muscles in her hips as Elsa’s hands moved, blue eyes still gazing into Anna’s own. Elsa’s breath hitched as she touched her chest and Anna wondered if her sister was as aroused as she was, if their conversations made Elsa as wet as they made her.
It felt entirely natural for Anna to slide her hands up her body and begin touching herself as she watched Elsa begin to drag her fingertips along her torso, creating spirals of frost in their wake. Anna pinched her nipples and rolled them between her fingers as she watched Elsa shift from light touches to scratches. And then Elsa started doing different things with the ice, but Anna found it more difficult to focus on her sister’s explanation, especially as Elsa’s voice kept wavering.
There was something about it, something about Elsa attempting to communicate to her clearly and being thwarted by the way her voice trembled and caught. Elsa, who never stammered in front of her council, was undone and stuttering as she touched herself right next to Anna.
It hardly mattered, really, what Elsa was actually saying, which was mostly a breathless, half-coherent explanation of what she was doing. It was the quality of her voice that set Anna on edge, and how their touching shoulders allowed her to feel the small jerks and motions in her sister’s arm. It wasn’t as connected as sitting back to back had been, but this way, Anna also got to see how Elsa’s back arched and how her hips bucked and made her ankles jerk at her self-imposed constraints, which sparkled as she strained against them in the room’s dim light.
“Look, A-anna.” Elsa waved a hand and created another set of clamps for her nipples. Part of Anna noticed that this pair seemed more refined than the last set, delicate and precise, and she whimpered, squeezing her her fingers tighter and wishing Elsa would make a pair for her, cool and tight and—
“They’re lovely,” she managed.
Elsa shot her a smile and their eyes met again. Anna felt her face flush a deeper shade as she slid one hand between her legs, where her fingers quickly became slick. Elsa’s eyes were the exact same shade as her ice. In the corner of her vision, she saw Elsa slip her left hand between her legs just as Anna started to circle a finger around her clit.
The contact was the usual mixture of relief at the indulgence and frustration that there wasn’t more of it, but with something else. Anna bit her lip as she looked into Elsa’s eyes and felt a rush of heat when her sister glanced down at her mouth briefly, flushing before she glanced back up.
Anna hadn’t even realized she was clenching the sheets until Elsa’s spare hand bumped into hers. Out of a habit, she turned her hand over and held Elsa’s.
Her sister’s eyebrows raised, and her lips parted as if she had something to say, but instead Elsa squeezed Anna’s hand back and threaded their fingers together. Anna wasn’t certain at what point her sister had stopped trying to explain what she was doing, but Anna was too preoccupied with attending to her clit and gazing into Elsa’s eyes to pay attention to whatever magic her sister was working between her own legs.
Maybe Elsa would be willing to give her a more practical demonstration later, place her hand between Anna’s legs and touch her like she touched herself. Then Anna could really pay attention to what she was doing, enjoying every detail of skill and whatever magics existed to augment Elsa’s touch.
The thought pushed her to the edge.
Anna moaned and shut her eyes, squeezing Elsa’s hand as she leaned her face into the shoulder beside her. Her fingers trembled against her clit as pleasure rolled up her spine and Anna bit down the urge to groan Elsa’s name as the image of her sister turning to the side and slipping a hand between Anna’s legs filled her mind. Then her thoughts went blank for a moment and she moaned something into Elsa’s skin.
She only realized she had actually bitten Elsa’s shoulder as her orgasm subsided. Sitting back up, Anna went bright red and let go of Elsa’s hand as she saw the red mark she’d left on Elsa’s skin. Immediately following her embarrassment came a wave of arousal at the sight. It was an odd combination that had Anna clenching her hips.
“I’m so sorry,” she said, gaze darting back up to meet Elsa’s.
But Elsa’s eyes were hazy and she reached out to hold Anna’s hand again with an absent smile. “It’s okay, Anna.” Elsa took a shuddering breath. “I... I liked it, actually.”
All the muscles she’d tensed suddenly relaxed. Anna felt as though she could melt into the bed. “Okay. T-that’s good.”
“Mmmnnn.” Elsa squeezed her hand again. “Don’t limit yourself on my account,” she murmured. “Some of the magic stuff I’m doing right now requires... requires some concentration. It might take me a little longer to c-come.” She took a deep breath. “But you, um, you keep going with yourself.”
Anna smiled as she settled back into her spot from before. “I see you’re not bad at giving instructions yourself, eh.” She pulled Elsa’s hand closer so the back of it was against her thigh.
A small grin tugged at Elsa’s lips. “I don’t think I’d mind taking a turn occasionally. Just sometimes. Can’t.... can’t expect you to lead all the time.” A small groan interrupted her and Anna noticed Elsa’s gaze trail down her body for a moment before returning to her face. “And I can tell you still want to,” she said in a breathy whisper that tensed Anna’s hips.
A smile tugged at Anna’s lips. “Can’t deny it,” she said before planting a quick kiss on her sister’s shoulder.
Elsa squeezed Anna’s hand briefly as a comfortable silence fell between them. Anna slipped a few fingers inside herself, rubbing the heel of her palm against her clit with each stroke. Beside her, Elsa seemed to be fucking herself with a shaped piece of ice.
“You’ve been so focused on me during our lessons,” Elsa said. “I just, just want you to focus on yourself tonight, to make yourself—” Elsa moaned, interrupting herself. “Make yourself happy,” she continued breathlessly, “Really really happy.”
Anna clenched down on her fingers and took a shuddering breath. “That seems rather self-indulgent for a teacher,” she managed, trying not to think too hard about the waver in Elsa’s voice as she told Anna to make herself happy.
Elsa’s shoulder shuddered against Anna’s as she shifted her weight. Anna tried not to concentrate on how the ice bindings made it difficult for Elsa to do so, but the sight just made her fingers slip as she started to desperately rub them against her clit. She closed her eyes, but the image lingered with the sound of her sister’s uneven breathing.
Then soft hair brushed her shoulder as Elsa leaned her head to the side. “Then indulge yourself for moment, Anna, please” she said, voice growing urgent, “I... I’m getting close and I w-want you to come with me.”
Anna moaned and gripped Elsa’s hand tighter. “Al-alright.” she turned her head to the left, burying her face in soft blonde hair. “I love you,” she whispered before taking a long, wavering breath.
The smell of Elsa’s hair, crisp and familiar, seemed to highlight every inch of their skin that was in contact, from their intertwined hands resting against Anna’s hip to Elsa’s head on her shoulder. She could feel through their bodies the rhythm by which Elsa was fucking herself and how it was speeding up with her breathing. By her feet, Anna could feel the bed shifting as Elsa strained against the restraints she’d put on herself and if she could have opened her eyes, Anna was certain she’d see her sister’s toes curling as she arched her back, just like she always did right before she came.
The orgasm rolled through her body as Anna bucked her hips against her hand, murmuring Elsa’s name over and over into her hair.
As the pleasure subsided, Anna took a deep breath and planted a kiss in Elsa’s hair before sitting up. She didn’t even remember having slouched so much against Elsa’s shoulder.
“I love you too,” Elsa said, lips brushing against Anna’s skin. Then she pressed a lingering kiss to the same spot before straightening up. She squeezed Anna’s hand before letting go.
Anna watched with her eyes half open as Elsa lazily waved her hands. With the motion, all the ice constructs disappeared. She stretched her newly-free legs and smiled at Anna. “Was that a suitable demonstration?”
No amount of playacting as teacher could keep a broad, silly grin from Anna’s lips. “Y-yeah. Er, hell yeah?”
“It felt... different,” Elsa said, letting herself slip down so she was lying on her back, “putting on a show for you without you having given me any orders.” A shy smile stole across her face as she stretched her arms above her head and looked up at Anna. “I... I liked that. I liked that whatever I did was sort of a surprise for you.”
Anna tucked her mussed hair behind one ear. She couldn’t keep her eyes from wandering down her sister’s body, “To be honest, I don’t know how closely I wound up paying attention. I became, ah, a bit preoccupied with attending to myself.”
“Mmmmn?” Elsa hummed and closed her eyes. “Maybe you need a closer look.”
Immediately, the only closer look Anna could imagine was kneeling between Elsa’s legs, planting kisses up her sister’s pale thighs as she watched her fuck herself.
Clearing her throat, Anna looked away to hide her bright red cheeks. “Uh, what kind of closer look?” Self-consciousness quickly chased off the last of her orgasm-high.
“You seemed interested in a more hands-on demonstration last time,” Elsa murmured, voice absent and careless. “I might even be able to do some things a bit better.” A small snort crinkled Elsa’s nose. “At least I presume it will be slightly less distracting if I’m working the magic on you, as opposed to on myself.”
Anna took a deep breath and idly ran a hand through Elsa’s hair. She hadn’t realized how strongly the smell of arousal had permeated the air around them. “So... You’ll work some magic on me and I guess I’ll just, uh, touch myself as usual?”
Elsa nodded, pushing up against the hand Anna had in her hair. “Mmmhmm. Are you still up for more?”
A small laugh escaped her lips before Anna could catch it. “I’m so very up for more.”
“Mkay.” Elsa patted the space on the bed beside her. “Lie down here then. I don’t think it’s possible for me to sit up anymore tonight. I’m just done sitting.”
“You dork.” Anna planted a quick kiss on Elsa’s cheek as she lay down beside her. “So... I’ll just leave the magic to your discretion and, um.” She shrugged and looked away. “Get back to my general routine?”
With a huff, Elsa propped herself up on her side, leaning on one elbow. “Minus the part where you act as though touching yourself is some sort of chore when we’re both aware you’re enjoying yourself quite thoroughly? Yes.”
Anna turned back in time to see a sly smile cross her sister’s face. The sight made her shiver as she slipped her right hand back between her legs. Her clit had only grown more sensitive over the course of the evening; touching it again caused her hips to jump.
The bed shook slightly as Elsa gave a light laugh. “I believe you had some a particular interest in feeling the ice on your skin.” She tilted her head. “Is it okay if my fingers touch your skin, or should I try to do the ice without contact?”
Anna took a deep breath. “Touching is fine.” She closed her eyes and told herself she wasn’t yearning for it. Still, she felt abnormally aware of her skin, which almost tingled with anticipation.
Then one of Elsa’s fingers touched her stomach, just below her ribs. For a moment, it was just a simple touch, and then Elsa traced it across to the other side, leaving cool spirals of frost in her wake.
Immediately, Anna opened her eyes and leaned back on her left arm to see. The thin layer of frost was already melting against her warm skin, sending droplets down toward the bed. Elsa’s hand hovered over her abdomen, as though uncertain whether or not to touch Anna again.
“Did you like that?” Elsa asked, voice soft and... tentative? Concerned?.
On a whim, Anna leaned forward and nuzzled her nose against Elsa’s shoulder. “Yeah,” she said, “I did. Would you do it again?”
Lying back down, Anna watched a cute smile spread across Elsa face. “I can do that.”
So Elsa continued to trace lazy spirals of frost up Anna’s thighs and tummy, between her breasts and up to her collarbone. At one point, she jokingly tapped Anna’s lips with a bit of frost.
When Anna winked and licked the snowflakes away, Elsa’s expression shifted slightly into something almost... needy? “Did you want me to make a pair of clamps for you?” she asked.
“Please do,” Anna whispered. She had been afraid to ask, afraid to push too far.
Elsa waved her hand, the same hand she’d fucked herself with earlier, over Anna’s breasts and a pair of delicate clamps materialized on to her nipples.
“Tell me how tight you want them,” Elsa said. “I’ll slowly adjust them until you say they’re good.”
Frankly, Anna felt too distracted—from touching herself to Elsa touching her to just everything—to know how tight she wanted anything, but when the clamps got a bit too tight, she tapped her sister’s hand. “A bit looser, just a bit.”
“Alright,” Elsa said, flicking her wrist to make the final adjustment.
The cool, consistent pressure on Anna’s nipples felt exactly like she’d wanted it to and sent a spike of arousal through her body. She kept touching herself, twitching a finger back and forth at the corner of her clit and holding back the urge to come too soon. She had the feeling that she could only stand one more orgasm tonight before she was done.
At some point, Anna wasn’t sure when, their legs had tangled up so that her left leg was between both of Elsa’s. Meanwhile, Elsa’s frosted touches became more insistent, her fingers pressing against Anna’s skin firmly.
Finally, Anna couldn’t stand it anymore. “Scratch me a bit, Elsa. It’s okay.” A shudder rolled up her back and since Elsa was too close not to notice, Anna decided she wouldn’t bother feeling embarrassed. “I want you to,” she added.
The sensation was everything she’d imagined, the warmth of Elsa’s nails scratching followed by the chill followup of the ice. Anna’s fingers kept slipping against her clit and she pulled herself closer to Elsa, who responded by wrapping her legs tighter around Anna’s.
Anna felt so close and wet and then, as Elsa’s legs spread her wider, she felt so empty it pulled her back from the edge. Biting back a moan, Anna leaned her face into the space by Elsa’s collarbone, trying to ignore the feeling and the fact that Elsa’s breasts were touching her skin.
Elsa slipped her arm under Anna’s head and leaned their foreheads together. She pressed a lingering kiss to Anna’s cheek and smiled.
A groan forced its way out Anna’s lips and she worked her fingers faster, trying for release, trying not to ask Elsa. But everything was so intense and she needed that orgasm badly and she wanted Elsa to offer but she knew that she wouldn’t, not unless Anna asked first and it wasn’t that there was a problem, she was just scared but sometimes needs outweigh fears so—
“Can you f-fill me? Please?”
Anna put her left hand over Elsa’s, where it had been spiraling frost across her thigh, and squeezed reassuringly. “You do the magic and I’ll hold it with you.”
Elsa’s fingers suddenly felt colder under her hand. “Y-you’re sure, Anna?”
She nodded, rubbing her nose against Elsa’s cheek. “Yeah. I... I feel so empty and—” a moan interrupted Anna and she smiled, apologetically. “And hey, isn’t this your practical demonstration or something?”
A light laugh shook Elsa’s shoulders as she laced her fingers with Anna’s. “You set the pace, alright?” she whispered.
Anna felt a wet ice grow under the palm of her left hand. Elsa’s hand gripped it around hers and they slowly maneuvered it into place.
“It takes a bit of concentration to maintain because the ice can’t be solid at the edges,” Elsa explained. “But it’s actually, um, a bit easier to do when I’m not as distracted.”
“Good to hear,” Anna smiled at Elsa before slowly guiding their hands closer.
Holding back a gasp, Anna’s eyes widened at the first contact. “That’s cold!”
Elsa’s eyebrows drew together. “Do you still want to?”
In response, Anna took a deep breath and started to push the ice inside herself. “It’s really fine,” she said in response to Elsa’s continued look of concern. “A bit surprising at first, but the cold hasn’t bothered me much since the true love frozen heart thing.”
“Oh.” Elsa blinked. “That’s handy then, I suppose.” Her hand squeezed around Anna’s. “Good to know.”
“Heh. Y-yeah.” Anna felt her capacity for conversation diminishing as she (and Elsa? Elsa was holding on too...) slowly started to thrust the dildo in and out, getting a bit deeper with every few movements.
The room was silent save for Anna’s labored breathing and the quiet moans she kept holding in, pressing her lips against Elsa’s collarbone to stifle the sounds. After a minute, they’d finally worked the entire length inside of her. Anna couldn’t resist a moan then, pausing their pace to hold it inside her, appreciating for a moment just how full she felt.
Elsa shivered slightly against her moan and Anna leaned closer. Elsa pulled them tighter together with her spare arm as they started up the pattern again, holding the dildo together as Anna moved her fingers faster. She was glad now that Elsa had her one leg trapped, because her hips kept jerking and throwing her fingers off from the spot she needed them to touch.
Anna reached a turning point as she remembered her thought from earlier, the image that had pushed her to her first orgasm that evening: Elsa reaching over and putting her hand between Anna’s legs, touching her like she touched herself. Anna, finally getting a first-hand experience with the magic of Elsa’s touch and of her powers.
Immediately, everything became frantic and urgent. The image was happening. Elsa was beside her, hand over Anna’s as they fucked her together.
“Elsa,” she gasped. “I-I’m so close I—”
A shudder rolled up Anna’s spine and she arched her back. Her hand slipped off the dildo and it was all she could do not to lose track of her clit as the orgasm built.
Elsa’s eyes widened. “Anna, should I—”
“Harder,” Anna whispered. “Don’t stop.”
Elsa’s breathing immediately thickened as she obliged and Anna couldn’t hold back the moan that pushed past her lips or the climax that followed it as she clutched Elsa closer, crying out her name again.
Despite the ice and cold over her body, everything felt almost unbearably warm for a moment.
And then Anna opened her eyes again and saw Elsa’s blue eyes and red lips that were saying her name, that looked soft and perfectly curved by her sister’s gentle smile.
“Anna... Anna... Anna,” Elsa said gently, finally audible as Anna’s hearing returned.
“That’s me,” she managed.
Elsa leaned closer and her eyes flickered down. And for a moment, nothing was as easy or simple as the moment when Anna met Elsa’s lips halfway on her own.
The kiss was soft and yielding, as unlike the driven, intense orgasm as could be, but maybe more intimate for it. Elsa’s lips lingered, uncomplicated and meant to press against Anna’s in all the right ways.
After a moment, they pulled back and gazed at one another. Anna felt the complications of the world rushing in and pushed them away for a moment to just smile as Elsa waved a wet hand and vanished all the ice from on and around them.
“Good demonstration?” Elsa asked.
“The best,” Anna breathed.
“I’m glad I got to make you happy, just a little.”
Anna leaned in and pressed a kiss to Elsa’s flushed cheek. “More than a little.”
She pulled back in time to see a smirk cross Elsa’s lips. “Oh, I’m aware. I do possess some modesty."
“Good to know.” Anna rolled her eyes as Elsa got off the bed and removed the extra blanket, then sorted the covers out so they could sleep under them.
And then, all too quickly, the lanterns were dimmed, she and Elsa were under the covers, and the expectation was that they would go to sleep. Anna fidgeted and bit her lip.
“We... We should do that again sometime,” she finally managed.
“Hm? Oh yeah.” Elsa sounded tired. “I assume there are still other lessons to be had.”
Anna cleared her throat. “Um, yeah, I guess so. But, um, I meant just... trying to make one another happy. Even if there’s no lesson or, um, demonstration.”
Elsa was quiet for several long moments. “You... you also want to make me happy? In, er, that manner?”
Despite her fear of rejection, Anna couldn’t resist a wide smirk that Elsa probably couldn’t see. “I actually had a few other manners in mind if you were amenable to sharing that happiness with me.”
A soft laugh answered her. “I am so amenable, as it happens to be, though not tonight.”
Anna snorted. “I can’t move like that any more tonight, Elsa, not even for your happiness.”
“That just means I did my job, doesn’t it?”
“Wow, make it sound like a chore, why don’t you.”
“Dork.”
“Your favorite.”
They snuggled closer until their foreheads were leaned together. Elsa’s lips shone even in the dim light.
Anna took a deep breath and tried to look away. Even after everything else, including the conversation they just had, kissing felt forbidden in some way. She sighed.
“What is it?” Elsa whispered.
“Nothing.”
“Anna,” Elsa said flatly.
Anna paused and had to hold back another sigh. “May... I kiss you?” she finally murmured.
Elsa opened her mouth to reply when Anna hurriedly continued. “Not just now, not just tonight, after the demonstration. I mean, may I kiss you when you’re happy and when you’re sad. May I kiss you when we’re just sitting here reading together and may I kiss you when we’re alone on a walk. May I kiss you when you’re tired and may I kiss you for goodmornings. May... may we kiss?”
Elsa’s breathless “Yes,” reached Anna’s ears only a moment before their lips connected again in soft kiss that expanded into a promise of more to come. After a moment, they pulled away and settled in to sleep in each other’s arms to dream of kisses not yet kissed.
