I taught sex ed to college students at one point, so you'd think i'd know something about sex education, but mostly it just means I am aware of exactly how much I've internalized incomplete, non-universal or just plain incorrect notions about sex and gender. So I'm not trying to be wrong at any point here, but also don't trust anything you read.

Specifically, this is a fictional story set in a crack interpretation of a fantasy universe, so if you own a cat, don't take this as any sort of medical guide.

I also apologize for the physics jokes.

-OOO-

"No faaaiiiirrrr," Weiss whined. She pouted and tucked her hands into her armpits. "How come Blake gets boobs before me?"

Blake kept her expression flat. She held her arms out as one of the maids wrapped a tape measure around parts of her torso.

"Well," said the tall maid, "We did have to guess her age, so maybe she's a little older than you?"

"An 'bosom buddies' s'more supposed ta be taken in tha metaphorical sense."

Blake had, actually always assumed she was older than Weiss. Possibly by a decade. At least mentally, haha.

Weiss only frowned in response. One of the maids wrote something down and started wrapping a tape measure around another part of Blake's torso.

"Well, Blake," Weiss said, "Now that you're getting measured, we can finally determine if you're alive or dead, kitty!"

Blake blinked. The maids blinked.

"But that also means we won't know anything about your momentum."

"I don't think you can model Blake as a subatomic particle, m'lady."

"Sure we can! Blakey's just an ion that's missing some electrons- aren't you Blakey?"

Blake blinked. "definitely." she deadpanned. "i'm positive."

Weiss winked. Then her face started beaming- maybe her hair floated a little, or her whole body did and her hair just did so as an extension of that, or maybe Blake just imagined it, blinded by how happy Weiss appeared to be.

"Oh Blakey I love you!" Weiss jumped on Blake, bringing them both to the ground. She started smooching Blake's nose and eyes and forehead. "Mwah! Mwah mwah mwah! I'm so proud of you Blakey! Mwah mwah mwah!"

Weiss hugged Blake on the ground, all over, and continued planting smooches on parts of Blake's head. Blake allowed it.

Eventually Weiss's enthusiasm waned. She hugged Blake's head and looked to the maids. "I taught her that pun, you see?"

The maids nodded. "Makes sense. Can we finish measuring Blake now?"

And Weiss jumped up, and she pulled Blake to her feet, and then Weiss looked up into Blake's eyes and frowned. "So Blake gets boobs first and she's taller than me, too? Extra no fair!" Weiss pouted.

"Blake was always taller than you," said the gaunt maid, "You just didn't notice because you mostly interact with her when she's in a chair, or on the ground, or otherwise lying horizontally."

"Maybe that's why she's taller than you. Lying around had allowed her spine to decompress, while in contrast, since you are always carrying her, your spine shrinks due to the weight."

Weiss stuck her tongue out. "That's not how that works. Also, I knew Blake was like a little taller than me since we met, but now she's, like, noticeably taller than me. Humph!"

Weiss walked up to Blake, at the front, right after the latest measurement was done and there was nobody there to screen Blake from the human girl.

Weiss stood at about Blake's nose, when she went to check.

Weiss looked up at Blake and smiled, her eye closed. "That's okay. It just means Blake's big enough to ride!"

The tall maid smirked and unsuccessfully suppressed a snicker. "I think Blake might need a special harness before you can ride her-"

The stocky maid immediately jumped to knee the tall maid in the gut. The gaunt maid and the young maid jumped into the pile via different sorts of wrestling slam.

Once the cloud of dust settled, the three surviving maids brushed themselves off and started prepping for the next of Blake's measurment rituals.

"Well, I don't think I need anything to ride her," Weiss said.

Blake was about to ask what Weiss meant, but then Weiss circled around and jumped on Blake's back.

Blake's legs immediately buckled. She strained for two heroic seconds before she fell down, on the ground, with Weiss on top of her, in a tangle of limbs. Blake's side ached, slightly.

"Blake noooo~" Weiss said. She rolled off of Blake and jumped up and helped the Faunus to her feet.

After Blake got up, refusing Weiss's offered hand, she frowned, and stood up in front of Weiss.

Blake tried to pick Weiss up, by the armpits. She failed to lift the human more than a few centimeters, after an embarrassing amount of straining.

Blake circled around to try the easy way to pick someone up, by hugging them around the chest, from behind, and then leaning back. Blake managed to lift Weiss only a little higher before loosing all her stength.

"Hee hee hee," Weiss said, "That's not how you lift people, silly Blakey."

"why can you pick me up?"

"Tha Missus went and got a right workout from luggin' 'round 'er body weight, everywhere, all tha time, no ma'er wot, since ya got here, is wat I think," The young maid said.

"More than her body weight, I think," said the stocky maid. "Not that there's anything wrong with your weight, Blake- you will always be beautiful, if your heart is beautiful. And it is."

The gaunt maid nodded. "You have a very excellent heart, from what I can tell."

Blake looked down at her limbs and stomach. At least three times she could remember, she had told herself she would start trying to work out a little more, and maybe try to eat a little less, but all of those self-promises had fallen through pretty soon after.

There was a cough as the tall maid respawned and managed to stand up. "I- cough don't think you need to worry about being shorter or less voluptuous than Blake, my lady," said the tall maid, "because being strong superceeds being tall or curvy in terms of mate fitness, for a lot of people. And besides," The maid managed to wink through a swollen face, "That just means you get to carry Blake everywhere. Romantically."

"Huh," Weiss said. She looked at the ceiling and thought, strenuously. "I guess that's right!"

Weiss picked Blake up, shifting her into a bridal carry.

And then Weiss shifted her arms and grip, so she could hold Blake straight above her head, arms fully extended.

Blake blinked.

The stocky maid put a finger up. "That's, uh, not- not exactly a romantic carry-"

"Ooh ooh, watch this," Weiss said, excitement in her voice.

Weiss tilted the appropriate arm so that Blake's body was no longer horizontal, with her head below the rest of her body. Blake splayed her arms out for balance, and she hissed, and as the blood started rushing to her head she could only feel hatred.

"You're upside down, Blakey!" Weiss said. She turned to the maids. "Blakey hates this!" Weiss giggled.

Blake flailed around a bit more, ineffectually.

And then Weiss put Blake down.

And as soon as Blake regained her bearing, she hissed and jumped on her human, pinning Weiss down and relishing her tormentor's squeals of terror, or perhaps delight.

Then Blake bit Weiss on the neck.

"Ahhh! Blakey noooo," Weiss screamed.

And after Blake was satisfied with her taste of Schnee flesh, she got up. She did not help Weiss up.

But after Weiss did get up, Blake had a random impulse that totally didn't suggest anything more about the nature of their relationship. She circled around to Weiss's back and jumped on her.

Weiss turned her head and smiled. "Oh, you want to ride me, Blake?" Weiss said.

The tall maid managed a snicker, despite the still present mortal wounds and threats from the other maids.

Blake waited for Weiss to fall down under her weight. Surely she could only manage to lift Blake up for a moment, after that earlier display.

But Blake waited. And waited.

And she waited even more.

Blake was starting to slide down. It hurt her chest a little, but she wasn't going to show pain in front of Weiss.

Weiss put her hands behind her and grabbed Blake's legs. She adjusted Blake on her back. "So, where'd you want me to take you, Blakey?" Weiss said.

Blake blinked. Well, if Weiss really was that strong, Blake could take advantage of it.

Blake pointed forward, to the hall. Weiss immediately barreled out the door and around the mansion. "Wheeee!" Weiss said, which was good, because Blake was able to say the same thing, except more quietly, and this way it'd be masked by the louder girl's squeals of delight.

(Behind them, one of the maids said, "Wait, we weren't done-", before fading out of earshot.)

Blake pointed the requisite series of directions to the pantry. Weiss carried Blake there. With her added height, Blake grabbed a small bag of tuna snackies from a tall shelf and piled them in her arms.

Blake then pointed the requisite series of directions to the boiler room, and the trash incinerator room, and the tower that faced the sun most of the day.

And for the rest of that afternoon, Weiss ran all throughout the mansion, with Blake on her back. Blake supposed it was 'fun'.

Eventually, Blake got dizzy. Weiss seemed a little out of breath, and there was a little bit of sweat on her brow, but she wasn't nearly as exhausted as Blake had hoped she would be.

"That was fun, Blakey!" Weiss said.

In the possible futures where Blake kept her new resolution to get in shape, Blake would start a muscle building regimen, in addition to her other training. The combat instructor insisted that the ninja way was the proper application of existing strength, rather than building up muscle, but Blake wanted at least to be able to pick Weiss up, so they could at least be equal that way.

But right after Blake made Weiss carry her all over the mansion, and right when it stopped being interesting to Blake, Weiss walked into the nearest guest room and flopped the two of them onto the bed.

Blake realized that, on second look, Weiss was panting, and had worked up a bit of a sweat. She smelled saltier than usual.

Weiss crawled over to Blake's side and nuzzled Blake's neck. Blake allowed it.

And they lay there, next to each other, just, existing together.

Blake turned to her human. Weiss smiled at her.

Blake took Weiss's hands in her own, leading her human's arms to wrap around her waist.

"Oh, did you want a huggy, Blakey?"

Blake blinked. She supposed she did. Huh. That was a weird thing to discover about herself.

Blake turned to stare at the ceiling, and the inexplicable confusion and frustration must have shown on her face, because Weiss gasped and hugged her in a way she probably thougth was comforting.

"Don't be sad, Blakey! " Weiss said, "Soon I'll hit my growth spurt and get boobs of my own, so we can be bosom buddies, in a literal sense!"

Blake blinked.

- A POSSIBLE FUTURE -

Weiss finds herself in one of those funks again. She had been covertly sizing up the bust sizes of everyone around her, but like, in a not creepy way. And like, sure, she was happy with herself, on balance, but sometimes she wasn't, and today was one of those times.

Yang was probably the most voluptuous of all the people Weiss regularly interacted with. And Yang was pretty built, too. Her workout was designed to build muscle mass but not exactly burn all her fat away, and apparently her mother had been particularly well-endowed, so she had genetics going for her.

And Pyrrha had a very athletic build (wonder why, haha) but a combination of how she dressed and good genetics meant she filled out her amazonian warrior outfit pretty well, and Nora seemed to build muscle without worrying about building up fat, or maybe it was also good genetics that let her also fill out her armor.

And Velvet and her team-member (whom Weiss hadn't really interacted with all that much outside of complimenting each other's fashion sensibilities when they bumped into each other while in the process of interacting with Velvet) were like two years older than her, so that was also probably not a fair comparison. Velvet did look pretty good for someone whose diet consisted mostly of lettuce. Well, whose nutrition, regardless of how much she ate that was indigestible for her anatomy. Or maybe parts of the fat in raw steak got absorbed by her digestion? Hmmm, Weiss hadn't actually asked if that was something that could happen with Faunus.

And Cinder and Glynda were well endowed too, but like, Ruby's educator friends were both like super old, and thus done growing so like, that wasn't a fair comparison.

But knowing that cognitively doesn't' help Weiss's funk. But it's not like a huge funk, Weiss is sure it'll pass soon, but she supposes she can at least talk about it to a sympathetic friend.

Weiss sits down at the lunch table with the friend she can most relate to, at least right now.

Jaune smiles and briefly stops playing with his dinosaur-shaped chicken nuggets and the share greetings.

"So Jaune," Weiss ventures, after a socially-acceptable amount of time has passed, "Do you wear a bra?"

Jaune blinks. "Well, um, no, because I don't need one."

"Okay." Weiss says. "I just figured that might be part of your wardrobe.

"oh, no, it's okay," Jaune says. Then he inhales through the corner of his teeth. "Like, I got the impression that wearing a bra when you didn't need one was so you could feel a certain way, and that's for, like, prepubescent girls, or transwomen, or the intersection of the two. There's probably some other groups too that might like the mental associations of wearing women's underwear."

"You wear women's panties, though." Weiss tilts her head, "Is that because your intention is that you flash people? I mean, the reason I know you wear women's panties is that you've ended up flashing people a non-zero amount of times."

Jaune blushes. "I- I mean, i'm not trying to flash people, it's just a little inevitable, because of the kinds of skirts I like to wear, and the kind of physical activity I do at a school built around athletic pursuits."

"See, that's why I have crinolines in my combat skirts," Weiss says, "It prevents that eventuality."

"Hmmm..." Jaune shrugs, "Well, I don't wear a skirt when I'm fighting, and I had kind of thought that I wouldn't end up doing a lot of three-dimensional moving in regular class. Maybe that was a naive assumption though."

To be fair, Beacon's regular education had been a lot more unconventional that Weiss had assumed it would be too. "So you're not intending to flash people. Why wear panties if, optimally, you would be the only person who knows?"

"Well, I would wear underwear anyway, so I figured, I'd wear the girl version. They're softer than guy underwear, too."

Weiss nods. "Okay, yeah."

There's a few moments of wordless food-picking after the conversation had died out.

"So if you don't mind me asking," Weiss says, "Why do you crossdress?"

Jaune looks to the side and makes shrugging motions. "I mean, it's all about wanting to look cute, because people treat you differently if you're cute. I think I've said as much before?"

Weiss nods. "Well, yeah, but- you achieve that by wearing what is explicitly women's clothing?"

Jaune's eyebrows flatten. "Yeah." He pontificates. "Because, see, despite how much people like Pyrrha and Cinder talk about the degendering of aesthetic norms, cuteness is still greatly inflected by gender. Like, a cute boy and a cute girl occupy vastly different places withing the overarching noosphere of 'cute', and thus provoke different reactions from others based on those associations.

Jaune waves the air. "I'm sure the sexual and/or romantic implications make up a large part of it, and I know there's also different connotations between being a girl, a crossdressing boy, and an assigned-male-at-birth girl, and I'm probably evoking a cross section of reactions to one or more of them depending on the observer, but-"

Jaune pontificates decisively, "But the point is, cute people- particularly femininely cute people- evoke positive attention across all points of interaction from most people. Like, cute people get away with a lot more, and people will just spontaneouslly help out or even give things to cute people, just because they're cute."

Weiss recalls back to points in her life, mostly with a mixture of regret and introspection, and she nods.

"And like," Jaune says. He slumps back in his chair. "I don't really have a lot going for me. I'm not good at fighting, or using my semblance, or manipulating dust, and I'm not particularly charismatic or persuasive, or very interesting as an individual, so at least I can be cute. I imagine a lot more people wouldn't like me if I wasn't cute."

Weiss opens her mouth to argue, but she finds she can't. Then she thinks of something. "Well, I mean, you are cute, but you shouldn't seek existential fulfillment based on how much people like you."

"But existentially," Jaune smirks, "What if I decide to pursue fulfillment based on much people people like me?"

Weiss decides not to get into a philosophical debate at this juncture. "So you're just, trying to leverage a social advantage?

"Well, I also do enjoy being cute. uwa~" Jaune gestures in a femininely-coded manner designed to elicit positive attention.

Weiss smushes her mouth and nods. "I guess I was curious, if your gender identity doesn't play a role in why you do it, if your sexuality does?"

"Weeellll, I mean, I don't dislike getting sexual and/or romantic attention from guys, " Jaune waves the air, "make that 'some guys', a lot of them are kind of creepy, pushy, and objectifying, but the point is, I'd like to think i'm open-minded enough that I'd consider a sexual relationship with the right guy. I mean, I think I feel the same way about girls, too- like, I like getting attention from charming and assertive women, but it'd kind of have to be the right woman for me to consider doing, like, romantic-type things - but the thing is, I don't really know how comfortable I am with going all the way with anyone."

"But you flirted with those strangers when we went to the mall?"

"Well, it's like, I enjoy getting attention for being cute, and sometimes I'll try to take opportunities when they arise, but that's not the primary reason I do it. And I try to temper how much I end up flirting, because I don't want to do anything further than just some light flirting and I don't want to give the wrong impression."

"So you're just a massive tease," Weiss says.

Jaune points at her and smiles. "Yes, exactly!"

Weiss waves the air. "I meant that, like, without the negative connotations of such-"

"No no, I got that from your inflection."

"I'm not judging you or anything."

Jaune scrunches his mouth. "I didn't assume you were. Until you said that."

"No no, I mean it. I had a maid like- like that, and it was fine."

"Ooo-kay..."

"And I do think you're cute," Weiss says. She then looks to the wall and remembers that Jaune tried to confess to her, once, and maybe that telling him he was cute was sending the wrong message-

"uwa~ Thanks!" Jaune says, and he seems to not take it the wrong way.

And there's a few moments of wordless food-picking after that, but it's less awkward. Until Jaune opens his mouth again.

"So, uh, Weiss," Jaune says, "Do you wear a bra?"

"No," Weiss states. Her eyebrows flatten. "I don't need one."

- A MORE DISTANT, POSSIBLE FUTURE -

"Mamma, Mamma," A young girl will say. She'll have white hair and two little Faunus ears atop her head, and she'll be growing up too fast.

And Weiss will smile and pick her daughter up by the armpits to bring in for the warmest hug. "What is it, my sweet little snow cub?"

"Um. Since I'm at that age where I'm becoming aware of myself and my body and stuff, I was wondering when my boobs would grow in, and how big they'll get?"

"Well sweetie, its mostly a genetic factor. You were born with a combination of both your parent's genes, so how big they'll get and when exactly they'll start growing depends on which of a certain subset of genetic information that determines your secondary sexual characteristics you've ended up inheriting."

"Oh," the girl will say. And she'll look into the distance and think for a little while.

"I hope I get mostly Other Momma's genes, because I want to be able to wear cute bras!"

And Weiss will smile and close her eyes and she'll tilt her head slightly. "Eat shit, sweetie."

- A POSSIBLE FUTURE -

"Boob envy?" Yang says.

Weiss scrunchse her mouth to the side. "Yeah..."

Yang bops the underside of her own left breast. "Like, you wish you had large breasts, or you want to, like, touch large breasts?"

Weiss scrunches her mouth to the other side and considers her words.

Yang chuckles. She holds her arms out. "Regardless, would a hug, at your level, help you out?"

Weiss furrows her brow. "Yes, but not because you- you have, you know."

Yang smirks, insufferably, "What if I don't know?"

Weiss puts her wrist to her brow and sighs, theatrically. "Not because you have magnificent breasts, Yang," she deadpans.

Yang laughs. "They are pretty magnificent."

They hug.

Weiss hasn't really told Blake about her and Yang being platonic snuggle buddies, but Blake was a firm proponent of snuggles in all forms, probably. And it wasn't like it was a secret- it just never really came up in the couple days since she and Blake started, like, smooching on the mouth, regularly.

"So what's got you down about boobs?" Yang says.

Weiss inhales through the side of her mouth. "You know, I thought about it a bit, and I think it's just that a lot of people in my life treated me like a child, and I mentally associated that with looking like a child, until it became it's own hangup."

"If it helps, I think you're the most adult member of team RWBY," Yang says. "And probably team JNPR, too."

"Thank you," Weiss says. "And I know that, consciously, and I know that it's kind of silly to put so much stock in that. But I still end up feeling a little inadequate, sometimes."

Yang audibly inhales and exhales. (It makes her breasts jiggle, just a bit). "Well how are the boobs of other females in your family?"

"My mom and my sister were reasonably well-endowed," Weiss still reflexively recoils from trying to think about her mother, "but I guess I get my boobs from the paternal side of my family. I'm told most of them have been pretty flat-chested."

"Well, maybe there's a chance you'll hit a growth spurt yet. And you can always see a flesh tailor, if it really bothers you."

"I mean, I don't think that's for me. No offense to people who for whom it is, but I think I just want to stop worrying about my breast size, rather than getting larger ones."

Yang nods. "Well, if you want, we can just continuously tell you you're awesome until you internalize it."

"Heh heh. Maybe."

Yang redoubles her hug. She lifts Weiss off the ground for a second, during the hug.

"So; you're awesome, Weiss!" Yang says, and there's a mischievous glint in her eyes, "So you don't have to be all meloncholic."

Weiss stifles her laugh. "Yeah, okay. I'll try not to be so D-spondent and more A-sertive."

"Try not to make such a mountain out of a molehill."

"You should know that's not quite my cup of tea."

"I'll make sure to bust down my assumptions, then."

Weiss laughs out loud, then. "Are you done?" she asks.

"I think I can rack up a few more," Yang says.

And Weiss reached critical pun threshold.

- PRESENT DAY -

Blake was mewling about the mansion for Weiss's amusement one weekend when some of the maids found the two of them. A few of the maids distracted Weiss with something silly, and the tall maid and the young maid approached Blake. Blake followed them to another room.

"So, Blake," said the tall maid, after the door closed and Weiss was out of earshot, "You're getting to be that age where you're becoming aware of yourself, your body, your budding sexuality and your conscious and subconscious gender performance, and how all that inflects every other aspect of your life-"

Blake blinked.

"We 'ere ta talk ta you 'bout pubterty," said the young maid.

Blake blinked. Honestly, she was sort of curious, but she had figured maybe she could sneak into one of the offices and look it up on the information network or something.

"And if you're wondering why us," said the young maid, who lifted a hairband to reveal some Faunus ears, "It's cause I'm equipped ta tell ya about coming of age as a Faunus. Mah memry's good and my oldest is going though the same thing, which means I get informational pamphlets from the school district.

Blake blinked twice. "wait, how old are you?"

"Thirty-five," said the young maid. The maid did some sort of mushing motion around the face region. "I moisturize."

"So why are you working here, then?" asked the tall maid. That implied that Blake wasn't the only one who made that assumption, so Blake was glad.

"Cos' this is the only job I could get in this economy, " said the young maid, "And they let me do a stupid accent on the clock, so I can't complain."

Blake blinked.

"As for me," said the tall maid. "And I'm studying to be an endocrinologist. Also, I didn't want to miss out on any potential sex jokes-"

The young (maybe that wasn't an accurate moniker? eh.) maid kneed the tall maid in the gut. "An' tha maid who wat went through puberty twice didn't feel like talkin' about it."

Blake nodded.

"So, le's show ya tha presentation, then."

Blake was brought into one of the mansion's conference rooms. Blake had wondered why there were conference rooms in a residential building, but then again, the adult Schnee's didn't really separate their work nand home lives.

Blake was sat down in front of a projector screen. The lights dimmed and a noisy machine spat light through an old monochrome series of slides, casting shadows on the screen.

The young made coughed, "So, since you're at tha age where your'e becoming aware of your body, bla bla bla,"

The young maid gave an overview of social changes common with the onset of puberty. Sepia slides with art-deco renditions of pubescent Faunus, dressed in clothing from three decades ago doing activities that had gone out of style four decades ago.

"So. In general, puberty is a time of changes and discovery. It is a time of coming of age mentally and biologically, but also socially, changing how you feel about what you look like and what other people look like."

"You'll notice new things about other people- their bodies, and their actions, or things you'd always noticed will take on new meanings when inflected by your growth and maturity."

"And puberty is a time of psychical changes as well!" exclaimed the maid, in time with an appropriate slide change. "In addition to growing taller and larger, your primary sexual characteristics will develop fully, your secondary sexual characteristics will become more defined, you'll grow some degree of hair on most of your body..."

A few slides went by showing more and more medical diagrams, as the Young maid explained changes in secondary and tertiary sexual characteristics and behavior common to puberty. Blake kept a straight face.

"If I can interject-" said the tall maid, "A lot of these changes cause a lot of people a degree of anxiety and other internal psychological distress. This is normal enough, and two popular ways of coping are- you can you can learn to accept yourself and your situation, or you can make changes so that you end up happy with your situation. Whatever works for you."

The young maid nodded. "Lookit you, being useful."

"Tch. This is an old presentation, half this stuff's been rethought, expanded, or debunked."

The maids turned back to Blake. "Specifically, as a Faunus, upon reaching sexual maturity, you'll start experiencing your estrous cycle."

Blake smushed her mouth. But ninjas were immune to embarrassment, so she didn't blush. Nope. Not at all.

"Feline-aspect Faunus are seasonally polyestrous, which means that, once you hit puberty, your gonads and secondary sexual organs will start maturing, and for several months during the year, you'll enter your Mating Cycle, and you'll go into estrus every several weeks during the duration of such."

"During estrus, you'll exhibit sexually receptive behavior, which is colloquially known as going into 'heat'. This lasts 1-3 weeks or until you successful mate. If you do end up mating, you'll go into diestrus for 5-7 weeks, in which you will not exhibit sexually receptive behavior, and if you don't, you'll enter interestrus for about 1 week, after which you'll experience another estrous."

"um," Blake said, "'mate'?"

The tall maid slid into center stage, "Oooo- Let's talk about sex!"

The tall maid coughed and adopted formal posture. "Sex, or 'mating' as is colloquially known by the Faunus youths and professional scientists- is any act of intimacy intimate in an erotically stimulating way between two or more consenting and actively participating individuals."

"Thas a really broad definition," said the young maid.

"Yes!" The tall maid pointed, "I mean, personal definitions will vary, and you really only need to care about the definition that you and any of your partners determine, but personally, I consider both foreplay as well as psychological stimulation to be under the purview of 'sexual acts'."

"Also, minor correction on the last point, but biologically, you'll only enter one of the diestrus stages after orgasm, which is traditionally accomplished only through mating and traditionally is the goal of mating, though the broader preview of intimate erotic stimulation includes much more than just rushing to orgasm."

"Oh! Orgasm is the discharge of accumulated sexual excitement, potentially accompanied by muscle spasms or bodily discharge, upon reaching a critical point of erotic stimulation. Basically, it's the point after which you suddenly lose interest in erotic stuff."

The young maid titled a head and looked quizzical. "You don't have multiple consecutive orgasms?"

The tall maid looked at the wall and sighed. "No..."

The young maid laughed, and then turned to Blake and waved the air. "Advanced stuff, don't worry 'bout it today."

Blake didn't think there was any danger of her worrying about that today.

"But anyway," the tall maid smirked. "This means that if you get really into edging you can stay in heat longe-oof!" The young maid kneed the tall maid in the gut again.

Blake didn't know what some of those words meant and there was no way she was going to ask.

"Aaaand- I think that's it?" said the tall maid, "I'll interject if I need to."

"Fer sooth," said the young maid. The slideshow continued. "Additionally, regardless of whether or not you're in estrous or in your mating cycle, you may experiences various psuedo-sexual proclivities. It is common to develop an inexplicable obsession with boxes-"

"It was around your age that I myself developed an inexplicable obsession with 'boxes'-"

The young maid kneed the tall maid in the gut.

The young maid coughed. "This is a manifestion of your nesting instincts. A box is a pre-made nest, you see. You'll be drawn to make a small area to hide, sleep, and potentially mate in, preferably just a little larger than two members of your species and elevated off the ground to give a vantage point from predators."

" You may also find, from here on out, that you release endorphins upon the application of lateral pressure to your torso."

"Any of these instinct may have been present to varying degrees throughout your life, but during puberty they'll become more pronounced and take on a more sexual nature."

The slideshow finished, and the tall maid hit the lights.

"Any questions?" asked the young maid.

Blake was pretty sure she would be content not learning any more about her body for the rest of her life. She managed to shake her head, slightly, at the ground.

"Alright! One more thing I wanted to teach you," Said the tall maid, right before switching the slides in the projector with slides of a newer, less stylized and more provocative aesthetic.

"Everything you need to know about BDSM, "began the tall maid, "So, there are three kingdoms of sadomasochism; physical, emotional, and power-play-"

"i already had this lecture."

The tall maid blinked. "What? From who?"

"tooth fairy."

The tall maid blinked again, before clenching both fists. "Really..."

The tall maid paced around the room. "The tooth fairies know that sex education falls under the domain of puberty fairy. This means war."

The tall maid then adjourned from the conference room, muttering something about revenge and taking the case before some sort of administrative body.

Blake, however, was dismissed, and she walked out of the room. She was quite proud of herself for having kept a neutral face through all of that.

So right after, Blake went into her and Weiss's room. She pulled some extra blankets out of the closet and bunched up all the pillows and blankets and some big, warm coats from the dresser all onto the bed, and she arranged them in some sort of igloo type structure.

Blake crawled around her finished nest in one last inspection.

And once she determined her nest was finished, she crawled into it. The entrance brushed against her side and back in an inexplicably satisfying way.

It was cozy, warm, with the perfect balance of light to be able to see by but not be annoying. The feeling of a low ceiling and close walls, made of warm, soft thing, was really comforting.

And it was really, really cozy. That seemed to be important, and worth saying twice. Blake stretched out her arms and back and her legs - she had designed her nest to allow for that- and she yawned. She rolled around in place and let the warmth and cozyness envelop her.

There was one thing missing, though.

Blake found Weiss and led her human by the hand back to her nest.

"What is it, Blakey?" Weiss asked, during the journey, through her giggles.

Blake opened the door to their room and led Weiss to the bed.

"Hee hee, did you make this blanky fort, Blakey?" Weiss said. "I like it! It's a Blakey blanky Bastille."

Blake released Weiss's hand and crawled onto the bed, in through to the entrance of the pillow-blanket structure. She turned around and held her hand out for Weiss to grab.

Weiss did so. "Hee hee, this is really cozy, Blakey! But how can you see in here?"

Blake nested up against the far wall, and Weiss huddled in the remaining space.

All she needed now was for Weiss to apply lateral pressure to her torso.

And all she needed for that was- and Blake sighed internally with all her being at the thought of this- to make a pun.

Blake inhaled. "Weiss."

Weiss flinched, but only slightly. She looked ecstatic. "What is it, Blakey?" She said.

Blake took another breath. She glanced at the pillow walls, and then at the blanket floor, and then, after the second try, she made eye contact with her human.

"what's a cat's favorite multiverse theory?"

Weiss giggled. "Am I supposed to say," she said, "'String theory'?"

Blake blinked. Shoot, that was supposed to be a rhetorical question, now Blake couldn't tell the punchline-

"Silly Blakey," Weiss said. She booped Blake's nose. "String theory isn't a multiverse theory, heeheehee."

Blake blinked. She felt her cheeks ignite in what certainly wasn't embarrassment. And for a similar reason, she couldn't make eye contact

Weiss pulled Blake's head in for a hug, as best she could inside the enclosed space. "It's okay kitty, it's a complex subject. I don't even make multiverse theory puns," Weiss said, "I just don't have the branes for it."

Blake blinked. She coughed.

Blake coughed again. She closed her eyes and held her hands up and braced, mentally and physically, for what she was about to say, and what it meant for her ongoing relationships with Weiss and for Blake's self-perception, that she was going to ask what she was going to ask.

"can you hug me?"

"Oh Blakey!" Weiss said. She hugged Blake. "Of course!"

Weiss then applied lateral pressure to Blake's torso. She also rubbed her face on Blake's neck and back, and smooches the side of her head which may have been actions that were adjacent enough to lateral-torso-pressure-application that they also triggered the release of endorphins into her frontal cortex. It was nice.
