Elsa heard that familiar knock on her door, the five beats that she'd spent most of her life ignoring. She was glad she didn't have to ignore them anymore. She was so happy to have a sister again. She placed a bookmark in the novel she was reading and set it on her nightstand, then stood up from her bed and, stretching, walked over to the door to let her sister in.
"I was worried you wouldn't answer," Anna announced glumly as she entered the room. "You took a while."
"You know that won't happen anymore, I promised. I was just finishing the page I was on, I'm sorry for worrying you," Elsa replied guiltily, Anna wrapped her arms around the queen, holding her tight. "Did you have a bad dream?"
"No, I haven't gone to bed yet. Oh, I'm sorry, you were probably getting ready to go to sleep, I forgot how late it was, I just had a date with Kristoff and I'm worried. I'm not sure what to do. He expects things, things that I don't know how to give him. What if I mess up? What if I'm not good enough? What am I even supposed to do? I'd never even kissed anyone before and I almost broke his nose the last time we tried to do that," Anna began.
Elsa laughed at that image. "How did you almost break his nose?"
"I closed my eyes too early, you don't close your eyes too early, you have to wait until you're kissing. I know that now," Anna explained, taking a seat on Elsa's bed.
Elsa stood, staring at her sister. "So you're worried that you're going to sleep with him and he won't like it? Kristoff loves you, I don't think there's any way you could disappoint him. Especially if he didn't leave you for breaking his nose."
"Almost! I didn't break it!" Anna stood up again, pacing around her sister. "What if I break something else though?"
"Something else?" Elsa asked, quirking an eyebrow up.
"His you know," Anna mumbled.
"Oh," Elsa gasped. "I wouldn't really know, I've never – but I can't imagine they're that fragile. Right? I mean they can't be."
"I accidentally elbowed it once when we were kissing and it poked me and I got startled and he doubled over in pain. I'm pretty sure those things are rather fragile," Anna insisted, flouncing back onto the bed and holding Elsa's pillow to her chest.
"Oh," Elsa breathed. "Well I'm sure he's used to it by now."
"But I can't just injure him every time anything happens!"
"Clearly you can." Anna growled back and then buried her face in the pillow. Elsa slowly walked towards Anna and placed a hand on her shoulder. "What can I do to help?" she asked, desperate to sooth her worried sister.
Anna glanced up at her, Elsa could almost see the gears turning in her little sister's head. "How could you help?" Anna mouthed the words back, testing them on her tongue.
Elsa stared back with a slightly worried expression. "Isn't that why you came here so late? I thought you needed my advice, I just don't know what advice I can give."
"You could help me practice!" Anna shouted as the idea struck her. "I've never done it with anyone before and you can help me figure out how to not hurt him."
"What do you mean?" Elsa asked, backing away slightly, not trusting whatever strange ideas were manifesting themselves inside that head.
"You could magic up something, like his erm," she gestured downward, "And help me figure out what I'm supposed to do. That way I won't hurt him when it happens."
"You can't even say it?" Elsa asked, laughing.
Anna grumbled in response. "This will work, it's perfect, I can't break it if it's ice, and I can get used to everything, and then I won't be too scared to enjoy myself when I'm with him!"
"Wouldn't ice down there be a very bad idea?"
Anna paused. "Your dress isn't really cold, can't you make it like that?"
Elsa considered this, it was true that Anna had never had any issue touching Elsa's ice dresses, maybe there was a way that she could prevent the ice from giving her sister frostbite in her nether regions. That didn't make it a good idea however, and she was still hesitant. "I'm not sure, maybe, but you don't think this is a little crazy? How would Kristoff feel if he knew you were doing this?"
"You're my sister!" Anna insisted. "It's not like I'm really cheating on him."
Elsa supposed that reasoning made sense. I mean it wasn't like they would run off together or anything, they were just trying to figure things out. It did sound kind of tempting for some strange reason. Maybe it wasn't the worst idea ever. "How would this even work?" Elsa asked, allowing herself to be drawn in to Anna's plan.
"You'd make it and then I guess you'd put it in me," Anna blushed. Saying it out loud like that made the whole thing sound a lot scarier. Fortunately Elsa had always made her feel so safe that it didn't seem quite as scary as it always had with Kristoff. She had backed out of it time and time again anytime things had started to head in that direction, but with Elsa things would be much easier, and there was no way it could be awkward or result in anything weird. Plus she couldn't get pregnant, that was a nice bonus.
Fear had started to bloom in Elsa. "I don't know about this. It seems weird, and I don't want to hurt you."
"Elsa," Anna pleaded, "It'll be fine. You're my sister, I trust you. I just need to find out what to expect. I'm so scared and there's no way Kristoff will put up with me chickening out forever."
"He can wait however long you need or he'll find himself frozen solid," Elsa retorted.
"See? You always look after me, that's why I trust you."
"I almost killed you," Elsa reminded her.
"I'm over it, it's fine. You're my big sister, you'd never hurt me intentionally, now will you pleeeeease help?" Anna whined.
Elsa rolled her eyes, but gave in. "Okay, fine, I'll help you. So how would I do this?" She tried creating the prescribed item, but having never seen one in person, she wasn't entirely sure what it should look like.
"Just make like a shaft, and attach it right here," she poked Elsa's pelvis, causing Elsa's eyes to go wide.
"Wait, you mean on me?" She panicked. "I thought you meant like in my hand."
"If it's not where it's supposed to be, then it doesn't help. I'm trying to learn how not to hurt him, how can I do that if I can't get used to someone being pressed up against me and everything?"
"I suppose that makes sense," Elsa reasoned. "But wait, so do we have to get naked, or are we just pantomiming? I don't know if I'm comfortable with this."
"Of course we have to get naked, silly," Anna giggled. "It's not a very realistic experience with clothes on. Where would you even put it then?"
"We shouldn't do this," Elsa insisted. "What if someone walks in? What if Kristoff finds out?"
"It's just sisterly love," Anna joked. "It'll be fine, now come on, get in bed." She climbed out of the bed and tried to drag Elsa back to it, tugging on her dress.
Elsa resisted her for a moment, but gave in, following Anna to the bed, and melting her dress off of herself, Anna stumbling when her grip disappeared. "Okay, but I don't know what I'm doing either, so we're taking this slowly. I don't want to hurt you."
"You won't," Anna said firmly. "It'll be fine. Now magic up that dick," she announced, finally saying the word as she struggled out of her own dress. She wished all she had to do was wave her own hand, there were so many layers. By the time she was free of her clothes, she saw Elsa naked before her, an icy phallus sprouting from her crotch. Anna gulped and blushed at the sight. "Oh, wow," she marveled. "Could you maybe shrink it a little, that looks ouchy."
Elsa obliged, though Anna was surprised to feel a little disappointed. "Are you sure you want this?" Elsa asked, still nervous and unsure of this endeavor.
Anna nodded, biting her lip. "I'm sure. We can start."
"I don't really know how," Elsa announced, staring down at her sister's sex. "Do I just put it in?"
Anna hesitated, "I think so? I mean I think normally you kiss and stuff first, but that might be sort of weird."
"I thought you wanted the whole experience," Elsa teased, a modicum of confidence surfacing in her sea of fear.
"You're right," Anna decided, her own fear dissipating. "Okay, kissing and grabbing and then you put it in." Elsa's lips met hers and both girls melted. It felt amazing, better than Kristoff's ever had, Elsa's lips were so much softer, and even the icy shaft poking against her thigh didn't feel as weird as Kristoff's always had through his pants. "Wow," she announced when Elsa pulled away. Both girls' faces were bright red. "You're a really good kisser, Elsa."
"So are you," Elsa panted, trying to hide her face, but with no way to do so. Anna ran her hands down Elsa's back, causing her to shudder involuntarily. "Anna," she began, but had no idea what else she may have been going to say when Anna's lips found hers again.
"You can put it in," Anna breathed when their lips parted. "I think I'm ready."
Elsa found that her sister was right, and the shaft of ice found its way without resistance. Anna whimpered in response. "Are you okay?"
"Mmhm," Anna moaned in affirmation. "I'm okay, it hurts, but it feels really good."
"How does that work?" Elsa asked.
"Maybe I'll show you when we're done," Anna retorted. Elsa was surprised to find that she rather liked that idea. As Elsa began to thrust, the two grew so lost in their actions, that all pretense and reason was lost. It was no longer about being ready for Kristoff, but about their hunger for each other. After only a few minutes, Anna broke, her finger nails scraping Elsa's back, leaving jagged cuts.
"Now it's your turn," she announced giddily.
