Yang quietly crept into her dorm room, long experience at not waking her roommates up lending to her stealthy abilities. Still, since there were often guests over, she took a moment while standing at the door to allow her eyes to adjust so that she might not step on anything or anyone.

Satisfied that all was as it should be, she pulled her pajamas out from her dresser and entered the bathroom, waiting for the door to close before she switched on the light.

So far, so good. The blonde brawler was usually the last one to bed, but every so often she'd roam the campus, either partying out late or just working off excess energy and restlessness. Tonight was the latter, but rather than work out as was typical she instead just took a nice, long walk.

It was a good opportunity for her to clear her head about a few things.

While she was outwardly supportive of her little sister's relationship with both her partner and the tall redhead who lived across the hallway, a small part of her had trouble letting go of the picture in her mind of the baby sis that needed held to help chase away the night terrors. The little girl who she'd basically raised ever since Summer had passed away.

And though it took almost the entire evening to walk this off, she'd finally managed to come to an acceptance of the fact that Ruby was truly not a little girl anymore. Age wasn't really relevant for her, being part of a prestigious Academy and in training to be a huntress, not to mention the leader of her own team, had lent a maturity to her beyond her years. And yes, while she could come off as immature at times, that was just her personality and would likely last well into her adult years.

No, if anything her actions with this burgeoning relationship cemented the fact in Yang's mind that her little sister had really grown up. And, when it came down to it, all she could do now as her big sister was to be there for her and support her wholeheartedly, no matter what she ended up doing.

Yang left her clothes in a pile in the corner of the bathroom, resolving to pick them up the next morning. She was in her sleepwear now, her luxurious hair brushed out and the rest of her nightly routine complete. The blonde turned the light off, pausing for a full minute to let her eyes adjust again before she silently opened the door to the bedroom once more.

As she crept across the floor towards her bunk, cognizant as always of her partner's propensity to wake up at the slightest noise, her ears perked up at a subtle rumbling. Pausing, she began to grin as she realized the source.

Blakey's purring, she laughed to herself silently. Must be havin' a good dream, wonder if it's about Rubes?

Her eyes glanced over towards her sister's bunk, only to immediately realize it was empty.

Huh.

Quickly picking up on the implications, her gaze next swiveled over to the bunk under her's where her partner slept. Sure enough, the lumps under the covers were far too large for just one Faunus girl.

And then she looked a little closer, and made out not just two, but three figures.

Well, how about that…

Ruby was facing her, mouth parted slightly as she snored so softly it wasn't really audible over Blake's purring. Yang's partner was behind her with her arm tucked around Ruby, raven hair spilling out on the pillow behind her. But then behind Blake was Pyrrha, long red hair intermixed with the black and her arm tucked around the both of the others.

Yang didn't want to feel like a creep or anything, but she really had to stop and gaze at the three as she squatted down by the bed on her haunches. All of them looked so incredibly peaceful, so very content, that it caused a bright smile to grow on her face.

But more than that, they seemed to fit together perfectly, like pieces of a puzzle.

Blake was about four inches shorter than Pyrrha, and Ruby another four inches shorter than Blake. The height differences made for such a perfect alignment of their bodies as they curled up together that it seemed almost like providence. Destiny, if you will, that brought them together.

Yang chuckled to herself quietly as she stood and carefully pulled herself up and into her bed. Must be tired if I'm gettin' all philosophical and the like. Still, she sighed inwardly. There's just no denying it.

Ruby's definitely grown up.

Ultimately, though, that didn't really matter to her. She might still give her little sister a hard time about stuff, or tease her as was her wont, but in the end she knew her job as a big sister was to look out for Ruby. Even if it meant getting out of her way sometimes and letting her live her life.

And finding the loves of her life.

Yang knew, or at least she was pretty damn sure, that's what this was. She was fairly certain they knew it as well, even if they wouldn't admit it to themselves or to each other, but the three of them, yes even between Pyrrha and her partner, were in this for the long haul.

Oh, man, she chuckled to herself as she faded into a restful sleep. Dad's gonna have a field day with this… Sure am glad I'm not gonna be the one to tell 'im…

She may be Ruby's big sister, but some things the brunette was on her own for.

A/N: So it came to me after I'd already decided on this OT3 that their height differences were perfectly spaced apart. According to the wiki, Pyrrha is 6'0" with heels. Figuring on 2" heels, that makes her an assumed 5'10". Blake is 5'6" (without the ears), and Ruby is 5'2". A perfect fit for a three-way spoon.

Little more introspection here from Yang, but I just wanted to address the aspect of the big sister that had raised Ruby from when she was a little girl. I've written Yang in other stories as having struggled with this aspect more, and I've certainly read some stories where it becomes a major problem, but I think in this case Yang would be somewhat impressed with how Ruby's been handling this relationship, and if nothing else in her eyes it makes her realize that she'd no longer a little girl.

I thank you all for the suggestions so far for a nickname to give Pyrrha, one that Blake and Ruby might be able to use. I think, in the end, DrZevil came up with a winner, but it will have to wait until a later chapter to come to fruition. Congrats! You get a metaphorical cookie, enjoy!

One last note, you people are seriously awesome. As of this morning this little piece of pure unadulterated relationship crack has 192 followers and just shy of 20k hits. And Sweet Mother of Pearl, 109 reviews! I continue to be amazed at the reception after only two weeks. Hope I can continue to provide more enjoyable fluffy fun to suit your tastes!

Demonic Angel C: Yup, I think Ruby's bed will largely remain unoccupied save as a study loft.

THB4: I'm definitely playing Blake up as the more, ahem, amorous of the trio. I come by that conclusion twofold, firstly because of the more salacious novels she reads, and secondly, it's always the quiet ones you have to watch out for.

Guest: I aim to please, hope my daily offering continues to provide relief from the harsh hiatus!

GateMasterGreen: Interesting nickname offerings… I did chuckle a little at ni-chan…

chaosglory626: As much as I like Ren's apron, I have to agree, Nora's is the greatest ever.

chaosglory626: Glad you're enjoying the super mega fluff!

happydeath3: Ehh, I appreciate the submission, but it doesn't really have the cutesy feel I'm going for…

RealTerminal: That's kinda the direction I want to go in, but 'precious' seems a little, I dunno… young? I like the idea though, lemme mull it over, thanks.

Amidamaru88: Lol, 'big red', that made me chuckle. And whoever could Weiss like? Time shall tell…

Jazzatron: Purruby threesome fluff is awesome. Glad you enjoyed it!

DrZevil: You know… I think we might have a winner here. Yep, I like it, lemme just figure out how to incorporate it… And I'm happy to hear you're a proud member of this crack ship crew!

guest21: The cuteness shall never end!

Stay shiny!
