Chapter Warnings: armpit/pheromone fetish, incest, mild alcohol use.

NOTES: Again, thanks for all the reviews! I'm going to do my best from here on to maintain a pretty steady pace with posting new chapters until the fic is complete. Apologies if life gets in the way at any point.

UzuKunoichi: It's not that simple. Part of the reason I made Elsa a larger woman in this fic is because it does tend to go hand-in-hand with having a desk job like hers, but part of it was to shed light on the all-too-prevalent fat-shaming in our culture. I never said Elsa is unhealthy for being "overweight" in the eyes of society; that is an assumption you made. Maybe Elsa could benefit from more exercise and a healthier diet, but maybe she already does exercise and eats healthy and she's still not a socially-acceptable weight. And either way, she's still a valid person exactly as she is. Just because she laments her size… people feel shame about aspects of their body all the time, and some do change themselves and that's fine. But it doesn't mean they're required to do something about those things to conform to what the world wants to see, or even their own ideal self-image. The question you should ask yourself is, does Elsa feel uncomfortable about her size because she hates it herself, or only because she laments how other people see her? I could tell you a dozen things about my body I despise right now (and before you ask, no, they don't all have to do with weight), but I don't have the time or money to change them. And it won't change who I am as a person if I do, anyway; I know I have more worth than my annoying body shape.

But to be honest, I expected some comment like this long before now, and I'm relieved yours wasn't mean or needlessly offensive. Just be careful how you throw around the extremely loaded term "obese" and how easy you seem to think it is for everyone to transform into a smaller size.

~ CHAPTER SIX ~

By the time they had a couple of mimosas in themselves, Elsa and her sister were pretty comfortable with everything. Of course, Anna was clearly comfortable with everything from the start, but Elsa had remained fidgety and uncertain, even through their drive to the brunch restaurant. Anna merely dropping a hand to her thigh made her squeak in alarm and nearly swerve into the next lane, and Anna had apologised profusely, withdrawing her hand to her own side and looking sick to death that she had scared her.

And then, at the next red light, she reassured her with a gentle kiss. Not one nearly as deep as the ones they had shared before Elsa took an extremely cold shower, but just a quick and intimate little moment. It put Elsa on edge a bit more, but Anna was definitely mollified that Elsa wasn't truly upset. Just startled.

This was a lot for her to work through. It wasn't that she was suddenly "in love" with Anna; not in the slightest! She had no interest in beginning an alternative lifestyle with any woman, much less her own sibling. As long as Anna was content with their current level of experimentation, and didn't push for anything more, she could at least process that it was happening — rationalise that she was so lonely that Anna helping her "take the edge off" wasn't the worst thing in the world. As long as no one ever found out.

But she still wasn't sure it didn't make her a bit of a letch. No matter how she examined it, there was no such thing as a "good person" who was okay with making out with their little sister. Not that she'd ever heard of, anyway.

Elsa refused to get back behind the wheel of her car just yet with the tiny amount of alcohol in her stomach. Therefore, they went walking along the street, popping into the occasional shop and seeing what it had to offer. Anna didn't make many purchases, insisting yet again that she had enough clothes and that she was trying to "live minimalist," which seemed to mean she didn't want to own a lot of material possessions. Barbies weren't the only item on her list of things that did not make the cut.

After treating themselves to frozen custard at a local stand, Anna holding them both in the car, they made their way over to Fjordman Elementary School, where they were barred from entering, of course. The doors were all locked. But they could walk around the sides and peer into the classrooms, get a look at the cafetorium. They swapped memories back and forth as they walked and ate, until they finally ventured around back to the playground. For a while, they just walked through the grass, dumping the empty custard containers into a metal trash barrel as they passed, then settled into the swings.

"My fat butt barely fits in this," Elsa commented.

"Beautiful butt," Anna corrected, as she had begun to do almost automatically now. "And yeah… even mine is a little tighter than I expected, and I'm a flat-ass. Guess we really aren't kids anymore, huh?"

"You do have an ass. Just not a large one, but it's there."

As she kicked off, she smiled overly sweetly and said, "Thank you. And my butt thanks you, if it could talk."

"Please don't make it talk," Elsa laughed as she began to swing, as well. Anna couldn't help but return the giggle. "You don't want me to think you stink, yet you make comments like that?"

"You don't think I stink. You think I smell amaaaazing," she drawled out.

"I do not!"

"Come on, don't lie." They swung in silence for a few more seconds before she added, "I saw your face. I'm not saying it means anything if you like how I smell, just… I don't like the idea of my sister hiding her truth."

"My truth? As if it's different from anyone else's?"

"Yes. I mean, things mean different things for different people. Your truth being 'Anna smells good' doesn't mean I actually smell good, just that you think so. But it's still a truth for you. Get it? The same with the kissing; you like me doing it, but it doesn't mean I really am a good kisser. Of course, putting that together with the other people who have told me I am, it starts to become a near-universal truth…"

Elsa had to swallow hard. Though they had brought it up very lightly, she was hoping not to get too deeply into the topic of their oddly sensual new activity. So she opted for the least dangerous topic. "Fine. I don't mind your smell, but I wouldn't go so far as to say I like it, okay?"

"I would." Still, her voice wasn't accusatory, and she was smiling. "That makes me happy. You liking anything about me does! I'm so used to you kind of 'putting up with' me that it's nice for you to compliment my handpan skills or body odor."

A little guilty flutter shot through Elsa. Did she really come across as that unpleasant? Biting her lip for a moment, she pondered how their relationship had developed. When they were younger, it was petty sibling rivalry, but she had done better about showing her sister once in a while that she did care for her. Ever since they became adults, the latter part had faded. Never on purpose, but it happened all the same. And with Anna leaving her behind, the resentment about that had turned many of her words more sour than was necessary.

She was a bad big sister. Not a terrible one, but not a good one at all. She wanted to cry when she realised it. Maybe Anna had also been a bad little sister sometimes, but it wasn't her responsibility to be "good". Not truly.

"Okay," she found herself saying as they swung. "I love how you smell."

"Do you mean it? Because that took a long time for you to tell me." After a heartbeat, she hurried to add, "And it's okay if you don't! I'm not trying to shame you for telling a white lie!"

"No, I… I really do. I'm just not used to saying things like this. Besides the fact that telling somebody 'Hey, I like the way you stink' is at least somewhat unconventional, you have to admit."

"Definitely," Anna laughed easily as she swung. "But like I said, I don't care. And I won't tell anybody else, if you're worried about their opinions. Your love of my smell will stay in the Chamber of Secrets."

They both shared a giggle at the reference to the books they had loved as children. Then Elsa told her, "But I've never enjoyed someone's scent like that before. Not without cologne or perfume in place. Any other time I've run into body odor, it has been disgusting! So… so it's strange to me, not disliking something I'm used to thinking of as 'bad'. But I do like yours, Anna, I… well, I think so, anyway."

"Wanna try it again?" Anna teased. Elsa didn't answer. Eventually, she let herself come to a stop next to her and tried again earnestly. "Do you? It's okay if you do."

If Elsa hadn't just been made aware of her own disapproval of her sister in their past, she would have refused. The whole idea of it was still too weird. As it was… "Sure."

Anna pulled herself out of the swing and walked over, brushing off the seat of her capris in case of dirt. Then she straddled Elsa's legs for a second as she considered. She shrugged off the light button-up shirt and tossed it wide, so it landed in the grass instead of the sand beneath the swings. Then she began to slide one leg past Elsa's hip.

"Wh-what are you-"

"Shhh," she said gently, grasping onto the chains of the swing before she raised the other leg, looping both around Elsa's waist and settling onto her lap. Her arms remained overhead, the tank she had been wearing under the shirt allowing Anna's unsightly tufts of hair to rustle in the breeze. "Be my guest."

"Anna…" Her eyes looked away shyly. "This position is… what are we doing?"

"Nothing we aren't allowing. If you want me to get up, I will. Otherwise, I feel very safe and very comfortable with you, alright?" When Elsa still didn't respond or otherwise move, she kissed the top of her head. "We're not doing anything bad. Even by Western standards… I mean, where's the commandment that says, 'Thou shalt not smell thy sister's pits'?"

"Maybe not in the Bible, but in the Bible of Common Fucking Sense…"

"Whoo!" Anna laughed, loud and free. "You swore! God damn, seems like you never do that! I dig it."

The light scent she could already catch from the wind was enticing her again. Still, she was sure it wasn't something she "liked" per se, but she felt drawn to its familiarity, anyway. After a few more seconds, she whispered, "I don't know… out here, in public?"

"Who's going to see?" she whispered into Elsa's hair, adding a little kiss at the end. "Revel in my hippie stench. You can even tell me it's horrible while you revel in it; I think that's kinda funny."

"Well… it's not really anything so bad. Just strange. I've never heard of anyone doing this…" Her face was drifting to the left slightly.

"Until now. Everything has to have a first, right?"

So she buried her face in Anna's armpit, breathing in deeply. It was too strong that close, but she didn't want to pull away, either. Truth be told, she didn't actually like it, after all… but she did. Her own thoughts conflicted each other! She absolutely could not classify it in the same category of "good smells"; baking bread, potpourri, simmering meat or a fresh-cut tomato. No, this was not good. But it was satisfying to her in a way she found infuriating.

"O-okay," she breathed against Anna's side. "I guess… I smelled it."

"Don't stop because you think I'm bored," Anna told her in a warm, gentle voice. One full of affection. "Or because you're scared. 'What will they think?!' Put that out of your mind. Do you want to do more?"

"I… I do." Her hands slid up Anna's back as she inhaled deeper, let the scent fill her. It was Anna. That was the most honest truth of why she was enjoying this insanity. Nothing else in the world smelled that way, and it was a smell she loved to encounter because of what it meant. She had always known the scent was Anna, but with her nose right there, amongst the soft hairs, it was potent and concentrated. She felt as if she kept inhaling, she could preserve her time with Anna for longer. Maybe save a bit of her forever.

Finally, after a few minutes during which Anna did nothing more than occasionally kiss the top of her head, Elsa drew back with a dazed look. She had been inhaling too much, and her head felt light. Anna pulled back to smile down at her, whispering, "Do you want to try the other one?"

"Wh-why?" Elsa managed to rasp as she slowly recovered. "It's… the same, isn't it?"

"Maybe. But I think you want to find out."

"Maybe I do." This time, she was less hesitant, and pushed her face into the other well, breathing in deeply. Anna giggled briefly from the sensation, then sighed in contentment, her other hand falling to Elsa's neck to hold her there, to reassure her that she wasn't going to pass any judgment. The scent filled her just as completely as before, and her stomach tingled, her head still light from being over-oxygenated. And as much as she hated to admit such a thing, even within her own mind…

Her body was responding. To this! Not that the scent itself was directly to blame, or the act of breathing it in, but knowing that what she was doing was taboo for several different reasons sent such a thrill through her that it reached into areas she had been trying hard to ignore.

She had to stop this. Her life was stable and calm before; chasing after strange, cheap thrills that she had no business entertaining would only destroy all of that. Even though she had never felt more alive than she did since…

Anna. It was Anna to blame for all of it, even if she wasn't directly connected to either the song on the radio or going into the adult boutique. Her own sister, whether she was doing it on purpose or not, was responsible for turning her from a normal, well-adjusted, productive member of society to some kind of budding deviant.

"Listen," Anna said when Elsa drew back at last, burying her face against her chest and shivering, "I… well, I still believe it's unnatural to cut body hair, but I'm not religious about it. So, um… when I get ready to fly out…"

Elsa's heart sank. Anna was still going to leave. "Oh…"

"Maybe I could shave this off… and, um, leave it with you?"

"What?!" Drawing back, she gaped up at Anna's face, blinking a few times. Then she scoffed, "Wh-why would I want that? Don't be disgusting, I- n-not that it's disgusting because it's you, just that it's a disgusting idea in general! No matter whose it was! I didn't m-mean to insult-"

Anna kissed her, and hard, cutting off her further babbling. It didn't last long, but just enough to stop her, and then she drew back with a quiet smile. "I want to do it. You can throw it away if you want."

"And I will," she promised her. Anna only grinned her own disbelief. "What the hell are we doing? Do you know? I'm… you make a lot of talk about this just being what 'two humans' do, but I've never, ever heard of one human sniffing another's armpit like it's actually something worth doing!"

"You know, there is a precedent for this, right?" When Elsa didn't respond, she went on, "Pheromones. My body puts out odors from its stinky places that will be appealing to some people and offensive to others." Her smile was a little shy, but also full of affection. "Now, it would be pretty uncommon for you to be tuned into pheromones from your own sister; usually, ours would be too similar. But on the other hand, sometimes we're attracted to the familiar, right?"

"No, Anna, I…" Her voice grew more desperate as she pressed, "You can't believe I'm attracted to you! Please, don't think that, I don't want you looking at me like I'm some kind of-"

"Not attracted to me completely. Just attracted to my pheromones." But her cheeks were pinker than Elsa remembered from a moment ago. "And I don't see that as anything other than flattering. Not disgusting, not sinful; I don't think you're broken inside."

Sighing, Elsa nodded after a second. That was better, even if it was still worrying. Little by little, her physical reaction to the "pheromones" was fading away, and she was grateful for that. At least she wouldn't give away that much.

Then something else occurred to her. "Do… you like my scent? I mean, would you like to try?"

"Not at all," Anna laughed. When Elsa bit her lip in chagrin, she giggled and whispered, "You're going to smell like Lady Speed Stick, Elsa. What's the point in me giving that a whiff? I already know what that's like."

"Oh," she laughed along with her, a little embarrassed but mollified. "I guess you do have a point… well, maybe I'll wash off my deodorant when I get home and you can try it out then. Or tomorrow."

Anna nodded easily, as if they were talking about what to have for dinner. "Sure. It won't be a true test, since you don't have any hair growth. The pheromones can't cultivate naturally."

"Okay, I have to ask: you do wash your armpits, don't you?" No answer. "ANNA!"

"Yes, you dope!" she giggled, swatting her shoulder. "I can't believe you would think I'm that gross! Wow, where is the trust?"

"The trust went out the window when you showed up on my doorstep, looking like you rolled in a sewer!" But Anna only continued to laugh at her, flailing her legs behind Elsa's back and holding onto the swing chains.

~ o ~

All the way home, Anna and Elsa discussed pheromones. Apparently, researchers were doing things with them and perfumes, trying to dial into the common thread of attraction. The goal was to make a singular scent that anyone could put on, and it would pair with their own natural one to increase their attractiveness. It sounded like pseudoscience and bunk to Elsa, but she couldn't disagree with the basis for their conversation.

Once back at the apartment, Anna caught her looking at her shoulders now and then while they worked on getting dinner together. At first, she did nothing, but the third time, she raised an arm and held it there, as if it were an everyday occurrence. Elsa felt like an obedient dog when she leaned over to inhale deeply, face growing hot, but Anna didn't chide her or tease her. She just caressed the back of her neck, then leaned in to leave a little peck on her lips when she drew back. However weird it was, Elsa at least felt sure that Anna cared for her.

After eating, they curled up together on the couch and flicked through channels, chatting about old topics and new ones, Elsa's job and Anna's travels. Once in awhile, she would point out something on TV that reminded her of a thing she encountered in the wide world, and Elsa listened in rapt attention. It was comfortable, genuine. Real time with Anna that she had missed.

It was another hour or so later that they fell to kissing again. Elsa resisted this time, trying not to turn Anna into her personal outlet for desires that should not be vented through such means. But Anna didn't press her. When Elsa eventually did initiate, it was all her own decision, and Anna responded readily with her hands sliding up to hold onto her sister. Again, the unholy act continued until she began to feel trouble brewing downstairs; then she backed off, merely lying pressed up against her while they watched a cooking show. Anna didn't make a single protest, either about the kissing itself or the abrupt ending.

When they prepared for bed, Anna stood in the doorway, watching Elsa rearrange her pillows and sheets. After a few seconds, she asked, "Do you want me to join you?"

"Join my what?" Then she glanced down at the bed and back up again. Slowly, she stopped what she was doing and stood up straight again, a foreboding tingle crawling up the back of her neck. "Oh. You mean… wait, what do you mean?"

"Sleeping. Instead of on the couch."

Elsa sighed with relief. "Oh, is that all? Okay, I… yeah."

"Did you think I meant sex?" When Elsa froze solid, Anna shrugged. "Just asking."

"Well… after what we've been up to lately, can you blame me? Pheromones and make-out sessions… I want to make sure you weren't expecting anything more."

Walking over to the readied bed and sitting down, Anna blinked up at her. "Do those have to lead somewhere specific? I just like kissing you. It makes you happy, which makes me happy."

"Is that the only reason you're doing it? Do you… I mean, is the actual kissing part fun for you, or not?"

"Of course. Who doesn't love making out?!" They both grinned. "And you're so good at it. Yeah, Elsa, I like the kissing itself. If I hated it, I'd probably let you know."

"Probably? Anna, I'm not- I don't want to force you into anything! Don't ever forget that — God, I can't barely force myself to just relax and enjoy it, so I definitely wouldn't want to make you do something you don't want to do!"

"Yes, I hear you," Anna whispered with an affectionate smile. "So, Sis. Am I in or out?"

"In. Well… I don't think…" Even just speaking on the topic was terrifying to her. Would Anna think she had such a dirty mind, such little self-control?

"Just say it. Speak your truth."

"If it seems like we might be tempted to go any further than kissing, I want you to leave the room."

"Okay," Anna nodded. "I promise; when we go to sleep, we sleep and nothing more. I respect your boundaries."

Belatedly, Elsa flushed at what she had implied. Of course they wouldn't do anything further! How could she even suggest such a thing? But Anna had agreed to the terms, so there was no sense beating herself up over their phrasing. Instead, she merely slipped under the sheets.

And they stayed true to their word. Anna snuggled up beside her, offered gentler, more chaste kisses, but did not let things even become as heated as on the couch — which was not quite as much as their first few kisses. Elsa had a hard time letting herself relax when she felt so awake, so invigorated! And even with her determination not to feel more than simple contentment, it still happened, but she kept herself from being obvious about it. That was the least she could accomplish.

When her arousal began to fade in favour of drowsiness, she found herself whispering to her sister, "Why doesn't any of this bother you? We're related, and doing things that are… I dunno. Weird things."

One of Anna's eyes slitted open briefly. Then she smiled just a little and whispered, "I love you, Sis. All I feel from you is love. You aren't just using me, and you aren't hurting me at all. So being upset about it… why should I? Why should I pursue negativity instead of embracing your love?"

Thought it was partly because she was too sleepy to disentangle the words, Elsa couldn't argue with that.
