Chapter two

Frostbite

Three knocks rang out from the other side of the door.

Elsa sprang out of the armchair, just catching herself before she started sprinting towards the door.

Stay calm, she said to herself. You're going to walk to that door slowly and calmly. Try to not make it too obvious how much you've been anticipating this.

Slowly, she started walking to the door.

Some part of her smiled at the irony of the situation. After the weeks of painful thoughts and deliberation it took to ask Anna about doing this stuff in the first place, waiting for just one day should have been easy in comparison. Instead, she had started to anticipate their next session almost as soon as the first one had ended.

She had been absolutely terrified that Anna might try to talk to her about what they had done during the day, in public. However, it seemed she had picked up on the need for secrecy. Aside from a few sly glances towards her, Anna made no indication that last night had been different from any other night. She had been the same cheerful, upbeat girl that she always was.

Elsa envied her sister's unwavering cheerfulness, as well as the fact that she hadn't turned into a complete nervous wreck. Nobody had said anything, but she was sure that at least some people must have noticed how on-edge their queen was. When a servant had asked her how she had slept last night, Elsa felt like all the blood in her body had rushed straight to her face. Anna's subsequent fit of giggles probably hadn't helped, either.

She had assumed that once she had asked Anna to do this, the worst of it would be other. No matter what Anna's response was, at least the anticipation would be over. But now that Anna had actually agreed to it, Elsa was asking herself more questions than ever.

Was this the right thing to do? Is it really okay for me and Anna to be doing these things? Is Anna really okay with this, or did I put too much pressure on her? How far am I willing to let this go? Is she willing to go as far as me? Will we even be able to stop ourselves if we keep going down this road?

Should I have enjoyed it as much as I did?

Elsa paused, her hand already reaching for the door handle. She smiled in spite of herself. Perhaps that last question was the one she cared about the most.

Because, make no mistake, it had been wonderful. She had enjoyed every second of their…session, far more so than she had expected to. Right now a huge portion of her brain was egging her on, urging her to open the door quickly, to start their next session as soon as possible.

Only…

In all the books she had read, she had never found a single case where two sisters had done what they were doing. From what she understood, it was rare enough for women to do it with each other, much less women that were related. Or…any set of relatives, for that matter. The only given reason for this she could find was that children born from close relatives were more likely to be deformed; it seemed, however, that most people simply never wanted to in the first place.

Was it wrong, then, to do these things with Anna? Especially when they made her feel the way she felt?

Another three knocks on the door snapped Elsa out of her unanswerable question. "Are you in there, Elsa?" came a soft voice from outside.

A pang of guilt rang out in Elsa's chest. She was making Anna wait out there, probably just as uncertain as she was, just because she couldn't make up her mind.

Anna came back here on her own volition. Clearly, she must have enjoyed it. And even if I'm not totally sure if it's the right thing to do, I should do whatever makes her the happiest.

Satisfied with this chain of logic, Elsa reached forward and opened the door. "Sorry about that," she said as Anna walked in.

"That's okay," Anna said. She looked down at her shoes, reddening just a little. "Truth be told, I was standing outside that door for a couple of minutes before I knocked."

"Oh," Elsa said.

She had meant to sound neutral, but it seemed Anna took it a different way entirely.

"Oh, not like that," she said hurriedly. "I was just nervous, that's all. I didn't mean it like I didn't want to do this or anything like that…"

Elsa smiled reassuringly. "Don't worry, I get it," she said warmly. "I'm nervous, too."

Anna chuckled awkwardly, clearly grateful for Elsa cutting her short.

It took about 15 seconds of them standing there, looking into each other's eyes, for either of them to work up the courage to take the next step forward.

"Okay, then," Elsa said, walking over to the bed. "Ready?"

"Uh, sure, I guess," Anna said, following her.

This time they both sat down on the same side of the bed, a few feet apart.

Anna cleared her throat, if only to break the silence. "So, I've been looking for some of those books you mentioned last time."

Elsa nodded. "I saw you in the library a while back," she said. "Did you find any?"

"A couple," Anna said. Her face started to redden again. "They were very explicit."

Elsa nodded.

"Like, REALLY explicit."

"Okay, I get it," Elsa said hurriedly.

"Sorry, sorry," Anna replied.

But even now, Elsa's curiosity got the best of her. "What kinds of things did you see?"

Anna looked at her feet, mumbling something Elsa couldn't make out.

"What?" Elsa asked.

Anna raised her voice just a little. "You know, like whips and stuff…"

"Oh," Elsa said. "Oh, god, no, I hadn't planned on going that far."

"I didn't think you were," Anna said hastily. "But I was wondering…how far ARE you planning to go?"

Elsa thought about it. "I…I'm really not sure."

Truth be told, I didn't think we'd get this far.

Anna thought about it for a while. "Okay, no problem," she said, making another futile effort to sound casual. "We'll just keep going until…" She struggled to think of what a good stopping point might be. "Until it doesn't feel right," she finished. "Sound good?"

"Okay," Elsa said.

Of course, part of me is already saying this whole thing isn't right, but I guess we'll just ignore that.

"All right, then," Anna said. She scooted closer to Elsa. "Ready when you are."

Elsa inhaled deeply. "Right," she said, tilting her head in towards Anna.

She wondered if Anna could hear her heart beating away like crazy. She was almost as nervous as she had been the first time. It was only by staring into Anna's beautiful sea-green eyes that she managed to calm herself.

She exhaled, and the two kissed again.

This time, it was Anna who pushed forward, her tongue pressing against Elsa's as she eagerly picked up where they had left off the night before.

Once again, Elsa was in nirvana. Any misgivings she might have had about what they were doing melted away, banished from her mind to make room for the tidal waves of pleasure engulfing her.

She wrapped her arms around Anna, savoring the warmth of her body. Anna shivered at her touch, throwing her arms around Elsa as well. Elsa clutched her sister tight, as if she was the only solid object in the world.

Elsa's hands ran up and down Anna's back, feeling the contours of Anna's body beneath the cloth of her shirt. Anna kept her own hands still, her fingers gripping the back of Elsa's silky dress.

Soon, however, she was gripping bare skin.

Within her mind, Elsa registered this change.

My dress is made of ice. Now part of it has melted.

These words echoed through Elsa's mind, largely ignored. At this point, Elsa was incapable of maintaining all but the most primal thoughts. What's a dress? What's ice? All that mattered was her and Anna, here and now.

When she looked back on this moment, Elsa would still never be sure why, exactly, she did what she did next. Was it a conscious choice, or just her body acting instinctively? She honestly couldn't say. And in the end, maybe it didn't even matter.

Elsa broke away from the kiss. Then, before Anna had time to react, she moved down towards the side of Anna's neck. Her lips closed around a small patch of skin, and she started to suck.

Anna gasped in surprise. Then, as Elsa persisted, she began to whimper, and soon the whimpers gave way to moans. Whether they were moans of pleasure or pain, Elsa couldn't tell, but it sounded like a little of both.

Elsa continued, and Anna's moans grew louder and sharper.

Make that a lot of both.

Even in her miasma of ecstasy, Elsa's protective instinct kicked in.

Just say the word, Anna, and I'll stop. I don't want to hurt you.

But Anna, it seemed, wasn't going to break. She continued to moan, and Elsa continued to suck.

Anna's back arched, and her arms fell to her sides. She clutched the sheets of the bed beneath her as she writhed from Elsa's ministrations.

Anna was starting to have trouble breathing. "Elsa…" she gasped. "Jesus…Christ…" She punctuated the sentence with a scream, one much higher pitched than her previous ones.

Elsa took this as a signal to stop. For now, at least. She pulled away from Anna's neck, breathing heavily herself.

Once again, the two sat there, gasping for air and trying to think of something to say once they caught their breath.

It was Anna who spoke first. "What…was that?" she asked, still breathing heavily.

Elsa waited a few seconds before responding, for more reasons than just shortness of breath. "It's called a love bite," she said.

"You mean…like a vampire?" Anna asked.

Elsa smiled. "Not quite," she said. "I didn't actually bite you, it was just a little nibble."

"That was…intense," Anna said.

"Sorry, you can't really be gentle when you're – oh, no." She looked at Anna's neck with concern.

"What?"

"Now that's going to leave a mark," she said. "Stupid – I should have thought of that."

Anna smiled. "Hey, don't worry about it." She felt the spot on the base of her neck, where a red circle was already forming. "Watch this."

Anna reached into her hair, undoing the bands and ties that formed her pigtails. Unbound, Anna's beautiful red hair cascaded down onto her shoulders, completely concealing the mark.

"There we go, like nothing ever happened," she said. "If anyone asks, I'll just say I'm trying out a new hairstyle. What do you think?"

Elsa didn't answer right away; she just stared at Anna.

Anna cleared her throat. "Something wrong?"

Elsa snapped out of it. "No, of course not. It's just…"

Might as well say it. What else could you say to explain that?

"…you look really beautiful with your hair down." She looked at Anna apprehensively, waiting to see how she took this praise.

Anna beamed. "That's so nice," she said. She reached towards Elsa's hair, pulling at the braids. "Let's see how you look with yours down," she said.

Elsa sat there patiently, waiting as Anna undid her braid. Once she had finished, Elsa felt her hair fall gently into place around her head and shoulders.

"How do I look?" she asked.

She had never seen Anna smile so broadly. "Gorgeous," she said.

Elsa blushed from the compliment. She shifted her head, feeling her silvery locks slide across her back.

Her fully exposed back.

Elsa only then realized just how much of her dress had melted from Anna's touch. Almost the entire back of the dress had been dissolved, all the way down to the waist. Her sleeves were the only things keeping the dress on her body, and even those were melted away in a few places.

Frantically, she reformed the dress around her, hoping it hadn't melted anywhere else. She had lost control of her powers before and created ice, but it had never occurred to her that she might have the opposite problem.

She cleared her throat. "Um, okay," she said awkwardly. "I guess that's enough for tonight."

"All right," Anna said, but she looked a little disappointed. She got up and started to walk towards the door.

"Same time tomorrow?" Elsa asked, worried that she might have scared Anna off.

"Of course," said Anna. "This was really fun."

She opened the door, then stopped. She turned back to Elsa, a smile on her face.

"Maybe next time we'll get the whole thing off, huh?"

And with that, she closed the door, leaving Elsa slack jawed on the bed.

Did she really just say that? Does she not understand the implications of what she said, or does she just not care?

It seemed her concerns about Anna not enjoying what they were doing were groundless. But while it would have been disappointing if Anna had asked that they stop, the concept that Anna was far more willing to do this than her was outright terrifying.

The situation was getting out of control, and not in the way that Elsa had anticipated. She hadn't been planning on giving Anna a love bite – at least not yet – but in the heat of the moment, she had forgotten the reason why. And now, it seemed, she couldn't even keep her clothes on. Everything was happening way too fast, and it seemed neither of them had the self-control to slow things down.

She'd have to do some serious thinking about where this was all going, as well as where she wanted it to go. She might also have to set some sort of ground rules with Anna, before one of them completely lost control. While she was at it, she definitely needed to do some more research, to make sure what they were doing wasn't wrong at all.

And maybe I should start wearing something under this dress.
