Prologue
The Letter


Huntsmen, and Huntresses. Warriors who fight the evils known as Grimm. Monsters born from negative emotions, as well as being drawn by it- are endlessly crawling upon the world of Remnant. What the world was before it came to be, no one knows. Each warrior is arms with the powers that be, to protect, to save, to conquer. Each Warrior has been tested by their choices, and each had to lived by them. And the consequences of those Hunters, affect the next generation.

Within the small island of Patch, two young huntresses, Ruby and Yang, sat on the couch dumbstruck, as well as somewhat awed. Only a few moments before they were all revving up Ruby's celebration party for getting into Beacon, and now Ruby had that specific look on her face that spelled "Oh God Not This Again", as well as feeling Deja Vu. Yang, her big breasted sister, laughed herself to the floor, not caring if her roars were as loud as gunshots.

"...Not this again." said Ruby as she shrugged her shoulders. Yang, meanwhile, was laughing up a storm, causing her semblance to activate in intervals every time she takes a moment to catch her breath.

"HAHAHAHA THIS IS A NEW RECORD-"

"THIS is why I tried to reinforce the wall with dust infused force resistance plates- so dad or you- won't break the house every single time Uncle Qrow sends a letter." replied Ruby hands on hips, voice monotone.

"And what? Let you improve the rest of the house with "upgrades"? Last time we let you "fix" the oven you made it shoot out our dinner!" replied Yang with a grin, eyes turning a peaceful lilac. "Talk about fast food- Even I have a the patience to just walk up and grab what's in the oven."

"HEY! It was a good idea- I get to tinker, you don't go to who knows where for Lien, and we don't get to waste any on repairs. It's a Win-win!" replied Ruby with a smile on her face. "And the Oven's the best thing that has happened to dinner time."

"That's only a Win-Ruby Exclusive. We couldn't even use the Oven- only you could. I mean, you practically just baked cookies and play a game with Zweii on who can eat the most in 5 minutes, while catching them either with your mouths or your clean plates."

"You have to admit it was a fun way to eat."

"...Yeah, It was a fun way to spend our boring nights. Cookie Night was unforgettable."

"So...what about dad? We're talking about food when he's somewhere out there in the middle of nowhere-" said Ruby, remembering the situation.

"We ARE in the middle of Nowhere Patch Road, 123 Green Trees Lane."

"YANG!"

Yang quickly pulled her sister into a one armed hug and ruffled her hair. Ruby struggled and tried to break free, but gave up at her sister's loving embrace. They broke apart and tried to clean up the mess that their hyperactive dad had done.

"So I wonder what did Uncle Qrow do this time?" asked Ruby as she used her semblance to carry and throw any debris to her sister.

"Dunno- but I'm gonna bet it's going to be about you again." replied Yang happily as she pieced the walls back together.

"HEY! I didn't even do anything over the top! At least- not recently..."

"You help stop a criminal rob a dust shop, joined a fight between two professional huntresses, and now you're on your way to Beacon two years early. Yeah, nothing over the top right there."

"...At least, not for the past few hours."

"Right. And I'm sure he isn't gonna give ya a pat on the back for causing trouble yet somehow turning the situation around in your favor."

"I told you! I didn't do anything recently that would warrant dad to...run for the hills?"

"Maaaaaaaaaaaybe he found out "that"" winked Yang as she stared at Ruby. Ruby dropped a rock on the ground before looking at her sister with a serious look on her face- at least "trying" to look serious. Ruby's face was red- and her mouth was turning into a loop-sided grin.

"He-hehehe-he too bad. He already knew I was into girls when Uncle Qrow told him in the backyard a week ago."

"Aww...I wish I'd been there. How did dad react?"

"He hugged me tight before yelling in happiness something about me not being corrupted or taken away."

"Yep that's dad." replied Yang as she "shaped" the broken wall into a nice square for repairs later on.

"He was about to say something else but was dragged away by Uncle Qrow."

"I think that news alone might have broke dad in the right way and became concerned."

"Say what."

"I mean, he won't EVER have to worry about dealing with boyfriends."

"Oh."

"I'm just glad that he was as accepting as you were."

"You're my sister Rubes- I could never hate ya." smiled Yang as she peered through the hole as she saw Ruby pick the last of the debris.

"There, all finished!" said Ruby as she quickly returned to the living room and sat on the couch. Yang followed suit, but sat on the lone sofa to the left of Ruby.

"So...wanna find out why dad ran out?" said Yang as she raised her legs onto the table.

"Wish we could Yang, but you know Uncle Qrow- he makes letters that only respond to a specific aura. If we even touch the letter that was meant for dad it would explode in a puff of smoke." said Ruby as she grabs a few cookies and begins munching them at top speed.

"Who said it was ONLY meant for dad?"

"Say what." Ruby paused and looked at her sister.

Yang slipped out a red envelope adorned with crow feathers from her cleavage, and laid it on the table. Ruby spat out her cookie and quickly checked the envelope. This was definitely the same letter her father held.

"Ya-Yang how did-"

"Found it on the floor while I was still laughing. I touched it and I thought it would explode- but it didn't and that means either I alone could read it besides dad or it was also meant for the both of us." Ruby swallowed whatever cookie she had left in her mouth. Ruby looked at her sister with a worried look.

"...Are you sure about this Yang? Dad might find out and get angry at us... And I'd like to have more time for tinkering and cookies rather than being in trouble thank you very much. Whatever is in that envelope is not worth the puni-"

"Ah come on, you're curious as I am right? Riiiiiiiiiiiiiiiiiiiiight? You saw how dad reacted right? One minute he was happy about you skipping 2 years from Signal, the next minute he reads the letter Uncle Qrow sent, turns blue and then started running outside to in a fit of manic laughter and tears. Even Zweii was scared." At that moment, Ruby stood up and looked around.

"OH GOD WHERE IS ZWEII!?" Ruby shouted as she quickly realized that her favorite Corgi is missing. She used her semblance as she quickly did a rough scan of the house to find no signs of Zweii. Yang quickly raised her hand and as if on cue- she grabbed Ruby by the hood and threw her back to the couch, in a sitting position.

"Oh he's fine~ He chased after dad as soon as he ran out." said Yang peacefully as she fixed her sister's clothes.

"...Sometimes I forget that despite your lax attitude that you have the eyes of a Nevermore."

"I'll take that as a compliment. So what are we waiting for? Now's our chance!"

"This is not gonna end well is it..."

"Hey! When did my plans ever go wrong?"

"In order of embarrassment or in order of Hair-related mess ups? Take your pick."

"...Let's just read the letter you little midget."

Ruby and Yang quickly grabbed the letter from the envelope, and started reading it. Minutes go by, and then Ruby and Yang dropped the letter to the ground with a red streak on their faces. Ruby was redder than Crescent Rose and Yang 's eyes were alternating between lilac to red all the while her hair glowing. It took awhile for them to process what they had just read, and after what seemed like decades, Yang broke the silence.

"That was...interesting. Uh..so..Rubes, you wanna squish the squash- shit I mean, wanna rub the turkey with some stuff-FUCK. Umm...Rubes?" Yang said in a slightly trembling tone. Ruby, however, was still in staring at the letter. Her mouth agape, her eyes dilated and her heartbeat was fast. Yang shook her sister, trying to get her attention.

"Rubes? Ruby...? You Okay sis?" Yang knew the answer despite asking the question. She gently laid a hand on her dazed sister and whispered in her ear: "...Rubes...It's a lot to take in-"

Ruby replied with a hand as well. Words alone is not enough to express her thoughts, instead she turned to look at Yang and stared at her eyes slowly filling with tears. Yang quickly hugged her sister after seeing this and held her for a few moments. "Yang...I.. uh...Rather, I..I'm not in the mood. I- This is a l-"

"Ssshhh.. We can talk about this after...dad has calmed down. I think he should talk first- we can talk after that, OK?" Yang gently kissed her sister's forehead trying to calm Ruby down. Ruby in response, hugged back. Yang's warmth was enough to ease Ruby back to her party mood, and somehow cause her heart to skip a few beats despite it beating like a a drum. Ruby felt her sister's warmth, and settled in her sister's arms for awhile.

"Sounds good." said Ruby calmly. She nuzzled deeper into Yang's chest, but had instead cause Yang to let out a moan in surprise held her sister at arms length. Ruby realized what she had done quickly thought of an excuse- lest she be blown to Vacuo by her sister's One Mean Punch.

"Sorry, you're eyes were still changing, so well.." Ruby let out her lovingly puppy dog eyes to calm down a slightly raging red-eyed demonic Yang. It worked- barely.

"Ruby! Rose!"

"EEEP!" On reflex, ruby tried to grab CR on reflex realized she doesn't have it, and just settled on preparing for the worst. It didn't come.

"Do-don't sur-surprise me like that! There are better ways to ca-calm myself down you know!" stuttered Yang.

"Eheheheheheehee~ You have to admit- you liked it~"

"..."

"Ya-Yang?"

Yang didn't answer, making Ruby worry. Yang would normally put her sister in a headlock before wrestling her down pinning her to make her say sorry, but Yang was silent. Eeriely silent. Ruby quickly went closer to Yang's face to check if everything was alright. The expression she saw her sister made made her snicker and giggle- Yang was blushing and her lip quivering. Her eyes nearly closed and her cheeks growing red like her eyes.

"Who knew my sister can make an innocent face like that?" teased Ruby. Yang lifted her head and quickly put her in a headlock.

"WHAT'D YA SAY!?" said Yang- her face once again exuding confidence. "JUST BECAUSE YOU'RE MY SISTER DOESN'T MEAN I WON'T DO THIS FOR COPING A FEEL, YA GOT THAT?!"

"the-there's the- yaaaang i kn-knowww..." gasped Ruby as she tapped the sofa. "...aiir... i need.. air... tap out.."


By the time Taiyang Xiao Long has returned home after his...breakdown, he noticed his two daughters playing Remnant, completely trying to forget that he ran out on his two children. Yang and Ruby noticed their dad back, and waved. Ruby was the first to get up and hug her dad, and was followed by a tackle-bear-hug by Yang lifting the two for a happier-though bone splinting-air-restricting hug. Yang laughed and let the two go and after a few gasps of air, the party had resumed. While Ruby and Yang were having a round on who can eat the most food- Taiyang discreetly grabbed the envelope that Qrow sent and began reading it. His expression hardened, but soon let our a small smile as he went onto deep thought, reminiscing old memories of bygone days.

"Summer...Ruby's becoming more like you everyday... Well, except the part into women, for once Yang didn't change her mind on that. Well, at least I know I won't have to deal with boyfriends. EVER. Well...I guess it's time for the break down...Kinda messed up now that I think about it."

He stared onto the pair sisters, and felt his heart lighten. He felt a tug on his legs, and saw that Zweii was begging for treats. He chuckled and grabbed a few pieces of kibble and gave it to his kind Corgi.

"Oh Zweii- later I want you too.."

Hours went by, and Ruby noticed that Zweii was tugging near her legs. Ruby, knew what that had meant, dad wanted to see her; Yang noticed this as well. Ruby looked at Yang and gave a crestfallen look. Yang, replied with a "Go." Ruby replied with a smile. She followed a beckoning Zweii outside and closed the door. Yang, went on to continue cleaning. When she picked up the letter that was still out in the open, she noticed a second folded letter addressed to her, by Uncle Qrow.

Surprised she didn't notice it sooner, she picked it, but it would not open. She then remembered about Aura-specific sealed letters and quickly used her aura to open it:

Hey kiddo.

I'm going to assume Tai ran out on you two, again. That guy really needs to know his surroundings more, even if its his own home. I'm not worried though, the house if off the beaten track and the likelihood of anyone coming there is low- privacy is our strongest point in the entirety of Patch. And even if someone other than you three makes contact with the letter- it'll go poof like always. I always loved that prank- Raven never saw it coming no matter how many times I sent in "fake" love letters.

Anyway, take the other letter and burn it, if it hasn't been burnt already. If Tai asks, tell him I told you to do so and tell him to contact me the usual way if he wants a to know the contents again. That guy is more of a nervous wreck than me, and I'm the one who becomes wasted. But enough of that and let's get down to business.

Since you've read the other letter, and if my ever suspicions are correct, Ruby also read it as well. In case you didn't understand because of the mumbo jumbo limbo that Atlas specialist tried to type up, Ruby's got a condition that finally decides to rear it's head. Summer had the same thing, but she had it at birth. Ruby didn't show signs of it, so we thought she'd be spared from the..."unique" experience she had. Heck, when Raven found out, she practically jumped on her and decided to help her best friend with that matter. Let's just say it started Tai's manic habit of breaking the wall and running outside.

"...MOM!" Yang screamed into the empty room, eyes flaring and knees trembling. If Uncle Qrow implies anything more about their parents embarrassing escapades, Yang might just lose part of her sanity. Or her lunch. Probably her "skillful" pun ability. Definitely her pun ability. Still shaking with rage(and embarrassment), she continued reading:

Don't get me wrong Yang, I'm not telling you our teams embarrassing secrets for nothin'. I'm sayin' so you know what to expect. If she is like what Summer was, then you better be prepared. I copied down that specialists important notes so even You and Ruby might understand:

Condition: GAHM

-Patient has increased Hormone activity
-Aura Manipulation increased to 123.56%
-Patient's Aura can latch onto others- "infecting" their aura. Effects currently unknown.
-Patient may induce pregnancy. Needs further confirmation-
-Aura output increases 145.23%

Other details in the letter are merely guesswork at this point- but the top 5 I've listed are 100% confirmed. Summer was the test subject- along with my sister to keep her company. When I heard about it- I thought it was an excuse that my sister thought up to hide the fact that she's bi. And if I'm correct, you're like her too. You need to learn from your good ol' pal ME about the real term of "secrecy"- something you clearly lack. Our house walls aren't THAT thick.

"...You dusty, perverted, old man." Yang yelled as she tried to not imagine her mother and her step mom in that kind of relationship. If this goes any further- Yang's image of her step-mom might shatter, along with her mom's cool "deadly image".

Take note of one of the effects: Aura Infection. Listen, I need you to be careful, and Ruby needs to be as well. We don't know what the extent of these effects are, and the only person who knows them is currently on a solo mission and is impossible for anyone to track. Anyone except me. I know my sis' methods well enough... I'm going make sure to find and make contact with my sis. It won't be easy- but the situation says she needs to come home. You two can speak whatever is on your mind when she returns. Oh, and your welcome- I know how much you want to see her. Normally she'd want ya to find her herself.

Meanwhile I'll try to break it down to Tai. He only knew half of the story(that runaway trainwreck), so I'll go explain to him the gist of it. If you think he and I had an already tense argument before, this will top it all off kiddo. Also enclosed in this letter is a special type of Dust-infused medicinal cartridge. You'll need it. Not for Ruby, but rather, for her "partner". And no, this is not Raven's pills. It was Summers. I've refilled and made them from scratch so do not use it lightly. The effects are temporary after the first use, but becomes permanent because it bonds with the user's aura and blood. Once it becomes permanent, keep a few around in case...well. Just in case. It's not easy to make those. One pill costs a fortune- ten times as big as Mistral's grand prize for becoming champion.

I've also attached a small note to Ruby, give it to her for me will ya. It lists the location of her congratulations present. It might take her mind off recent events. If not, I expect you to help her through and through, but again, that goes without saying.

-Qrow

P.S. Whatever happens, you're still both my favorite nieces. No matter what anyone else says.

Yang searched for the cartridge along with a small red piece of paper. She stared at the strange rainbow colored decorated cartridge and noticed that in it are a total of 50 multi-colored pills infused with dust. She sniffed a few and each of them have a scent of different kinds of fruits. She closed it and pocketed it for later, and quickly burned the letter meant for Tai. Yang then thought on what her uncle just said:

"Take care of her...huh.. Heh. No need to tell me that."


By midnight Ruby, Zweii and Tai returned home and both head to their respected rooms. Tai bid his sleepy headed yet still red as rose Ruby a goodnight hug and head to his room. Ruby, still red for multiple reasons, went to her room and saw Yang sitting on her bed in her tank top and panties. Ruby ran and quickly hugged her sister. Yang returned her now red cherry-of-a-sister a hug and patted her softly. Ruby cooed and snuggled deeper into her sisters arms and then proceeded to lie down on her lap. She and Yang stared for a few moments, before-

"...I..uh had a long talk with dad. I wasn't expecting him to give a girl, the talk. At least, not after saying I'm into girls."

"Well, to be fair, you DO act on instinct, like Uncle Qrow. He's just, ya know concerned."

"HEY!"

"You made a Oven that shoots out food, ESPECIALLY cookies."

"Point taken."

"So, little sis, how are you feeling?"

"...I..um..have mixed feelings about this."

"Whoo ho ho I can tell."

"On one hand...I feel like..this isn't going to change a lot, but then...it feels like, like-

"Don't be like that sis- Everything will be fine."

"...Right... Umm...Yang?"

"Yea sis?"

"Actually, I have...a rather personal question."

The mood changed. Ruby's still smiling and blushing face made a total reversal and looked away from Yang. Still blushing, for some reason, Ruby went into deep thought. Yang, still preparing herself, and her thoughts as well, waited with bated breath. She heard a calming sigh, while still caressing her sister's head.

"Yang, can I be ho-honest..? Ruby's stuttered on the last moment. Yang quickly straightened her face and looked back to her sister's eyes. Yang knew what that look meant, Ruby was serious-as well as scared.

"Go ahead little sis. Don't worry. I'm here." said Yang as she continued to pat her head. Yang was feeling determined and somewhat serene, yet her heart can't stop beating faster than it normally would.

"I...Do...We...Do you think I'm a freak..?" asked Ruby as tears build up around her eyes, yet keeping her calm demeanor.

"No." Yang quickly answered. Ruby shook her head as she asked again, fearing it might have been false.

"Yang...am I...a freak... to you...?"

"No, Ruby-

"It's cause dad or uncle Qrow said so to take care of me so you said "No"? Because it-"

"No Ruby but-"

"Or is it because from now on I won't be able to have a "normal" relationship-"

"Rubes-"

"Because I feel like a freak- I mean I'm already having issues going to Beacon alone and now this- this makes me feel like I won't have-

"Ruby!" Yang shouted. Ruby flinched at her sister's hoarse, or what seemed to her, harsh tone. She waited as she tried to calm herself down. Yang took a deep breath and tried with all her might to concentrate her thoughts into careful words.

"No, I do not hate you. Nothing will change that. Hey, people will just...like you who you are, not cause of what you have. Alright." said Yang softly. Ruby was stunned; speechless. Ruby hugged her and wiped whatever tears on her shirt. "In fact, it...makes me love you all the way more."

Ruby started to chuckle before turning into a garbled laugh-mixed tears. Yang just smiled at her now calming sister.

"Is it because of...? I-I mean, you aren't exactly the model sister. If it is, then that would explain why you're lack of self-restraint, you're promiscuity, and the fact you aren't wearing your bra underneath your shi-" said Ruby jokingly, but was cut off by Yang as she quickly grabbed her skull and tightened it to an iron grip. Ruby became terrified at her sister's now red eyes.

"Continue...and I'll make sure you will never walk again."

"i'msosorrysopleaseletgoofmyheadnowithurtssomuchlikehowzweiinevergetsanydogtreatsforthepasttendaysbecauseweignoredhimforwhoknowshowlong."

Yang calmed down and resumed her patting. Ruby sighed a relief. That was almost Life and Death. Life was more important. "Although, it does open some possibilities..." continued Yang.

"And here I thought you'd be serious for once."

"Oh. But. I. Am~" teased Yang. Ruby gulped, making Yang laugh. Ruby then laughed back and both now feel like all their tensions from the letter melt away.

"This really reminds me...of Mom."

"Yeah, apparently she was the same as you and my mom did with it her-" Yang then covered her mouth noticing she had gone with the flow. She cursed her Uncle's influence. Ruby was shell-shocked, then blushed then laughed.

"I didn't need to know that, but at the same time, I'm glad I got to hear that. But where did you hear that from? It's not like you to tell stories like that- Wait... Did you go through Uncle Qrow's Po-"

Yang once again, tightened her grab. Ruby flinched, but kept her smile at her sister.

"Stopstopstopstopstop-joking-head-pain-blood-Yang-cookies-." said Ruby, making a brave front, while internally, praying and thinking of her last will and testament. Yang once again relaxed her grip.

"So...you believe me now?" Yang asked back. Ruby back to Yang, and smiled. She was relieved and yet...she could not help be filled with..new sensations. Yang wiped away her remaining tears and held her close to her chest. Ruby's feelings was starting to well up even more, but was feeling more comfortable as her sister eased her conflicting emotions. Thoughts of Yang's soft breasts then started to encircle her mind, and her sisters comforting voice. She nuzzled deeper into Yang's breast and started to smile. Yang was blushing was trying to not let out a small moan as her sister nuzzled deeper. Ruby stopped realizing what she had just done, also realizing what had happened hours ago.

"Uh..UH This isn't what it looks like- I mean- I shouldn't have done th-"

Yang quickly hugged her sister. Ruby was surprised by her sister's actions but soon (or finally, in this case) noticed certain things. Like, Why was Yang letting her cuddle her boobs? Why is she only in a Tank top and panties? She would normally be in her sports bra and jammie pants when going to sleep. Why was Yang so...motherly(wait- she does when I'm sad-durr)? Why isn't she putting up a fight? And the most important question of all, why is Yang in her bedroom anyway? She has her own room.

"I hope you're done, cause It's my turn now Ruby." said Yang as she put her at arm's length.

"Ya-Yang?"

"Well, Uncle Qrow said to take care of you- but first I needed to know what exactly are we dealing with. Everything in the letter was too much for me to understand. And he sent me another letter that made things easier to understand."

"O...K? Not surprising, but OK?"

"And...after reading the letter in detail, I decided to do a little digging, and guess what nada-zip-zilch. So...the next step is to just...look at the source. Strip." grinned Yang

"...Oookay this is getting reaaaallly awkward so I think I might just go to bed and- wait this is my room-"

"Oh come on~"

"YANG!" retorted Ruby as she tried to inch herself away, distracting her sister, her face already red.

"And it's also high time I also teach my sister about these things anyway- dad might have...poorly explained things and you know it."

"YANG I- Actually you're right- he did a poor job explaining it a while ago and I have no idea what he was talking about."

"An Opening!"

"YANG!?"

Yang then flipped her sister upwards, twirled her around as she began stripping her sister. Ruby caught by surprise tried to escape, but her face accidentally hit Yang on the face-kissing her on the lips. Yang came to a halt. Ruby went still, looking into her sister's eyes. After what seemed like moments- they broke apart, and faced each other sitting down. Both sisters blushed, and looked away. Ruby being left only in her underwear, had many many thoughts go through her head, but the last action just made her realize something- that was her first kiss.

"Ru-ruby- That- I- kiss- that- I didn't mean too-" Yang blurted out.

"...that was my first kiss..." said Ruby as she touch her lips, caressing it.

"I-I'm sorry I-"

"No Yang, it was my fault- but..."

"Ye-yes?"

"I didn't know that...what was how kisses felt like..." smiled Ruby innocently. Yang's heart skipped a beat.

"If you were saving it for someone- I-I'm sorry-"

"...No it's OK, I might have botched mine anyway on the first attempt- well- I was right wasn't I?" chuckled Ruby.

"...I-" Yang was at a loss for words, so she held her head down to hide her deepening blush. Ruby continued chuckling because of how Yang was acting. Her normal hyperactive act first think later sister was reduced to a mere innocent maiden in front of her. Yang pursed her lips at the lingering feeling- she had kisses before, but when she did it with Ruby- there was... a spark. The fleeting feeling was addicting, and she wanted to feel it once again. As she was about to look back at Ruby- she noticed her sister's panties growing dark- as well as a small bump appearing.

"Uh...Rubes."

"Hrmm?"

"I think...I may have found your "condition.""

"Huh?" asked Ruby. Yang pointed downward and Ruby looked. She saw a small bump, making her eyes widen and freeze on the spot. Yang, filled with curiosity, slowly made her way to her sister and tried to remove her soaking panties. Ruby didn't protest- she was as curious as her sister was. As Yang pulled off the only remaining cloth blocking her sister's purity- she let out a yelp of surprise as she saw her sister's small clit slowly swelling. Ruby- being new to this- was just shocked and frozen in place.

"...So..." said Ruby trying to break the silence. Yang was still looking at her sister's clit- making her feel...uneasy. She quickly closed her legs to grab Yang's attention. "Could you stop staring at it?"

"So-Sorry."

"So...now that you've looked and checked at my "condition" can you please go to your room?"

"Yeah, No."

"Why?!"

"Because, I said I'd explain things properly. I don't want you to be...experimenting and ending up getting hurt- OK?"

Ruby had no answer for Yang- she was right in every way tonight- something she thought she'd never see the day. And so Yang began re-positioning herself as she and Ruby had a "better talk". Talking about the birds and the bees, the bees knees, the ins and outs, has left Ruby with a new sensation. Yang took notice, her sister was twiddling her thumbs, the surprised expression on her face, the infinitely reddening cheeks the almost unbearable gnawing hunger building within her- she had to keep herself at bay. After an hour- they were midway through the talk as Ruby felt...a new sensation.

"And so, you always have to aim for the-"

"Umm...Yang? Can we...stop?"

"Oh come on sis, you've said that for the past hour and really it's getting old- you need to know these things-" continued Yang, her face serious but still red at the same time.

"But..I.."

"But what?"

"I'm feeling...weird."

"Of course you feel weird- this is new to you and you have to get used to-"

"I mean I feel weird...down there."

"...Oh."

"Yang...I don't know but I'm feeling tense..."

"You're feeling heat sis."

"Heat? I don't..have a fever-"

"I mean, you're feeling aroused- you're flipped switch- an itch you need to scratch- something a rub can ease- You know- You feel turned on." teased Yang.

"You didn't have to put it like that."

"Don't worry sis- I felt the same the first time."

"...this has got to be the weirdest sister bonding moment we've ever done."

"Yeah No Duh."

"So...how do I..."

"...Ruby are you asking me how to get you off?"

"I-I have no idea what that means, but...yes?" said Ruby innocently. Yang reacted by smiling and positioning Ruby to her side.

"You just basically asked me to have sex with you."

"...WHAT?!"

"...Eh, worth a shot."

"Again, WHAT!?"

"OK, so, you ready?"

"THIS IS CROSSING THE LINE ISN'T IT?"

"And since when did that stop me?" grinned Yang.

"I! You! WE! I- I have- THIS IS- UGH FINE! Maybesurewhynot-I...think so."

"Just let me take the lead. I'm slightly more experienced." said Yang with confidence.

"PFFTT. Riiiiiiiiiight. You're as experienced as me Yang."

"Oh really?" teased Yang as she suddenly pulled her sister's chin to her sister's lips once more. Ruby caught off guard, went into shock once more. Yang quickly rolled her tongue deep into her sister, dancing about, taking in the feeling that had caused a spark in her. Ruby's gaze soften as she let her sister do the work. Both sisters held on until they gasped for air, but not before leaning on each other's shoulders. Yang with the reflexes of a lion, quickly tore her sister's bra away, along with her own- exposing her own mounds for her sister to see. Ruby, trying to control her heartbeat took deep breathes. She was slowly feeling the heat intensify with each breath she takes.

"So...how was that? Experienced enough for you?" gloated Yang behind her embarrassing face. Ruby was gaping her mouth- she had no idea what to say. All she knew that it was...enticing.

"I'm not done yet sis, the practice session just beginning!" gloated Yang as she straightened up as she kissed Ruby on the neck. Yang didn't know why, but her body is acting of it's own accord thinking that this might feel right. Ruby let out a yelp- as well as a exciting moan that even surprised herself. Yang heard, and intensified her smooches.

"Ya-yan-yang- I feel..I feel...!"

Yang kept on kissing, and soon enough she grabbed her sister's breast and started playing with them. Ruby was helpless in her sister's attacks, and held in her moans- hoping Yang wouldn't hear her. Yang, ever the optimist, pulled herself to Ruby's breast and began teasing it with her tongue. Ruby let out a long moan as she went rigid. Yang felt her own heat increase, as she started to rub her thighs together.

"Le-let me handle this sis." replied Yang in a sultry voice, continuing her onslaught on her sister. Ruby couldn't bear it any longer, and gave up stifling her moans. Yang proud of what she did, decided to reward her sister. She pushed Ruby back to the bed, as she re-positioned herself on top without breaking contact as she switched her hand to her sister's thighs. Ruby was in an extremely vulnerable position- her eyes were glazed, drool coming out of her moaning mouth, her lips trembling in excitement and joy- she was enjoying every touch her sister had made.

"...I...I..!" said Ruby as she felt something build within her. She was near the point- and a little push is all that's needed to finish this. Yang, reading her like an open book, she inserted two fingers into her sister. Ruby felt that, and pushed her over the edge as she let out a loud moan as her back arched backward. Yang was proud of what her handiwork had done, but soon turned her gaze to her sister's lower lips as her clit suddenly shot upward in length morphing as her sister did in tandem. Yang quickly let out her fingers as she sided off her sister.

Yang was shocked, for the lack of a better term, to see that her sister had grown a part that was only meant for men- she looked and gazed at her sister's dick- pulsing in time with Ruby's high. As soon as Ruby returned from her high, she slouch back into the bed, and took deep breathes.

"Ya-yang that was...amazing~" said Ruby. Yang did not reply, as her eyes were still on the new weapon between Ruby's legs. "Ya-yang? What's wrong? What are you look-"

As Ruby turned her gaze from her sister- she felt her eyes widen as she looked downwards- She felt herself once again go red and shot upwards sitting down to take a better look. Yang remembered what had happened look at her sister.

"...You, uh...grew that after.. you came." said Yang, trying to not to look at her sister.

"Ya-Yang- What- what is-"

"...I think you know, Ruby." teased Yang, as she turned her gaze on her sister. Ruby looked back, hoping this was all a dream that she's experiencing.

"Is-IS THIS-"

"Well, at least now you can safely be sure that you can go on a date with any girl that catches your fancy~" joked Yang, trying to lighten the mood.

"THIS IS NO TIME FOR JOKES YANG!"

"I'm being entirely serious Sis." continued Yang, as she held her laugh in. Ruby puffed her cheeks as she folded her arms.

"So... what now Yang?" Ruby looking away from both sights, trying to look mad.

"Well...I wasn't...expecting this. But...this situation...IS PERFECT!" said Yang gleefully. Ruby turned to her, thinking her sister might have gone mad.

"...Oh boy here we go.."

"What? You're as curious as I am~"

"That's your excuse so you can "experiment.""

"I won't deny that, so let's get started-"

"There's no way you're going to let this go, is there?"

"NOPE."

"And people wonder how do I put up with a sister like you."

"Hey, it's their loss~"

"...Just...be...gentle" said Ruby as she looked into her sister's eyes, her mouth quivering. Yang, noticed and smiled, and simply nodded.

"Yes, now please leave it to me...Little Rose~." Yang winked as she crawled closer to Ruby. Ruby had finally given up and accepted what's gonna happen and what will eventually happen. Whether her insides was dancing out of pure lust or something else she did not know, what matters is right now, she had a hungry lioness to take care off- or to let her be take care off- this is confusing.

She felt her heart skipped a beat as Yang quickly touched her new appendage. She held in once again her moans as her sister check if everything was real. Soon enough, Yang began rubbing it with her hand. Ruby, now covering her face, except her eyes, stared at her dick being fondled by her sister. She could not believe it until she had seen it, and now it was real, and now Yang is pleasuring her and making her feel on cloud nine. Yang then stopped and raised her head to look at Ruby's eyes. Ruby wanted the feeling to continue, and looked at Yang trying to beckon her to continue. Yang just stared back, grinning. Ruby looked away, trying to not show that she was immensely enjoying this. Yang grinned wider, as she made her own sister enjoy the new sensation that is only unique to her. She lifted her head near Ruby's ear without stopping her motions, and whispered into Ruby's ear.

"If I didn't knew any better, I'd say you're more...naughty than I am~" Yang teased Ruby as she began tracing her ear with her tongue down to her neck. Ruby just moaned back as the feeling wasn't just intensifying- it was doubling up. She looked at Yang, eyes filled with longing.

"Yang...this..is.."

Yang smiled as she stopped her teasing hand- she quickly tore off her panties leaving only her in her birthday suit, and re-positioned herself as she put her hips on Ruby's face. Ruby- having no idea what to do, just laid back waiting for instructions. Yang quickly without thinking, put her sister's dick in her mouth while she started fingering her sister once more. Ruby let out a stifled yelp as the new sensation spread inside her. Yang intensified her actions, making Ruby moan. Ruby caught again unguarded, let out a loud moan of ecstasy.

"I'm so glad Uncle Qrow sound-proofed this room for me. This would be embarrassing if dad hears us.." Ruby thought to herself, but suddenly a she realized her trail of thought: " WAIT- DAD! IF DAD FINDS OU-Ooooooohhh~~~ OHHH~~~~~"

Ruby's thoughts was pushed out as she began to reach her climax. She continued panting like Zweii on a hot day, as Yang continued without stopping her actions. Ruby then noticed Yang's lower lips starting to ooze, and without much of a thought began playing with it with her tongue. Yang let out a small moan still with herself on Ruby's dick. Ruby, at her dazed state, just began licking her sister up like a bowl of hot soup and Yang began to convulse in excitement. As the two sixty-nine each other, they soon started to reach their maximum state, with Yang, climaxing first. Yang let out a moan as she squirted in Ruby's mouth. Ruby caught it in her mouth, not wanting to ruin her bed, and swallowed it as it entered. She swallowed as her dazed look slowly disappeared as a new feeling began welling up down below.

Yang, despite coming down from her high, continued to finger and suck her sister off, and Ruby, soon let it all out. Yang swallowed her sister's load and her fingers got sprayed by her sister's nectar. Eyes nearly rolling back, her tongue nearly all the way out, and drool and seed coming out of her mouth.

"Ya...Ya...ya..Yang...that..was..amazing~"said Ruby as she pushed Yang softly to her side, as she saw her dazed-high-sister coming down as well. Ruby, not knowing if what she was doing was right- grabbed Yang's arms as she drag herself towards her dazed sister, kissing her. Yang now was the one surprised- but soon gave in as her little sister was for once taking the lead. Ruby rolled her tongue to taste her own, and took some in her mouth. Yang pulled Ruby apart, and dragged off the bed, both of them landing with a thud on the floor. Yang quickly crawled up with her upper body leaning on the bed as she knelt, her lower half quivering. Ruby, taking notice at this, stood up with all her might despite her legs feeling like jelly.

"Ya-yang what are you.."

"...Take me~" said Yang as she looked at her sister her eyes full of longing.

"But...you just told me that...this is... a girl's..." said Ruby, her face filled with shock.

"...I can't wait, and I...rather you do it- I'm afraid I.." said Yang as she trailed her voice off. Ruby, understood at once.

"...might strangle your guy when you do it the first time? That's soooooooooo like you Yang." joked Ruby.

"...shut up."

"...but this...goes beyond...practice...It's-it's-!"

"...Ruby, Please-please...take..me~"

"...Yang, your not thinking straight- this is-"

"Ruby! PLEASE!" shouted Yang. Ruby looked at her sister dead in the eye- Yang was near tears- the position she's in was already embarrassing enough- having to hear her sister say no is making her shake. Ruby took a deep breath.

"...I love you Yang." said Ruby as she began to align her hips with Yang, without breaking eye contact.

"I love you too, Ruby." Yang felt her sister as began to poke her. Ruby was trying to figure out what to do, but Yang, without any hint of patience, quickly grabbed her sister and lead the way. As the tip was about to enter her, she quickly gasped, and stopped her sister.

"Just to let you know sis- I will never ever regret this. So neither should you." She then slowly guided Ruby into her. Ruby seized up on the new sensation, as Yang tried her best not to feel the pain of losing her virginity. As she finally reached the back of Yang's womb, They stopped for a few moments, trying to let the feeling sink in, or out.

"Yang...Yang...! This..is.."

"Ta-take-take it slow...move..slowly~ Yes...that's it."

Slowly Ruby moved her hips into Yang, slowly getting used to the sensation. Yang's lilac eyes immediately went red as she can no longer hold in her tension as she timed her hips with Ruby's thrusts. Her breasts began to swing, breathing uneven as she began to moan as pleasure took over. Ruby bent downward and quickly grabbed her breasts as she increased speed. The feeling intensified, as Yang began reach a new level of high. Ruby, now going as fast as she can, groped her sister's breasts as she pinches her nips, increasing Yang's pleasure.

"Ru-Ruby...you feel...amazing!~"

"Yang, you feel..good! I..don't want to stop!"

"Deeper! DEEPER!"

The forbidden pleasure both sisters were drawing them closer to their limit. After what seemed like hours, Ruby felt the again, the sensation building up again on her abdomen.

"Yang..I think...It's happening again..."

"Ruby...you can stay inside, it's OK.."

"But...but-"

"Don't worry- just- do- it!"

"Bu- but..!"

Ruby realized too late as she climaxed and blew her load into Yang, Yang soon climaxed as well, clamping down on Ruby, intensifying the feeling Ruby was experiencing. Ruby then slouched onto Yang, as Yang too, relaxed her legs. She felt Ruby's hair fall past her face- breathing in her sister's scent. It smelled of cookies, with a large hint of strawberries. She felt comfortable. She felt together. The feeling then changed when Yang felt a slight tinge above her clit. She tried to look down, but Ruby was still blocking the view so for now she just assumed it was her shrinking back down. Ruby, coming down from her high, raised her head and kissed Yang on the lips again. Yang, kissed back. As they broke apart, Ruby also got off Yang and sat on the cold floor, her legs weak. Yang turned around, exposing herself for her sister to see- she was oozing below.

"Yang...that was amazing! So this is what Dad had felt like with Mom!" said Ruby hoarsely, still panting.

"Yeah, though please don't put that image on my head, for both our sakes."

"Ye-Yeah...Sorry..."

"So Ruby~"

"Yes...?"

"If you ever...need relief...so whenever you have..you know..."

"Are-are you sure...? I mean...?"

"I did say I would help you. I'm your sister after all, and now I guess...Fuck Buddy? SisToy? I don't-"

Ruby quickly grabbed her sister as she forced her on top of her. Yang, caught off guard, was now laying on top of Ruby, who was smiling and letting out tears of joy. She began rambling into incoherent words that Yang could barely understand. She rubbed her sister's head as Ruby recounted her last embarrassing moment.

"There, there Rubes. Just...be sure to tell me. And...I'll help."

"...Another Round Yang?" asked Ruby, now looking at her sister with longing. Yang felt her heart skip a beat, and quickly nodded. Yang quickly positioned herself so she was on top of Ruby- and she herself plunged back on the still pulsing rod Ruby had. They once again resumed their love- with Yang taking the lead.

After several rounds, switching between different positions from Yang being held up by her sister- to Yang grinding back down on her- both had had enough as they both lay on the floor exhausted. The last position- Yang on her back with Ruby on top facing each other, cuddling as they take in the moment. Yang and Ruby stayed together in the same position for awhile, not wanting to forget the feeling of each other. Soon enough, Ruby began to feel her heat rising again as she soon began sucking Yang's breast again. Yang noticed this and tried to break Ruby off. But Ruby still hyperactive, refused to. Yang then slowly nudged her sister away but Ruby went back in and locked her sister in place.

"Ruby~ Could we wait a little while longer..?~ I'm sti-still a bit sore~"

"But I'm still in the moooood~"

Ruby slowly took out her dick and as soon as she let it out, she stabbed it back in Yang's butt. Yang let out a yelp of pain, surprise, pleasure and garbled moans as Ruby began pumping again. Yang again felt herself orgasm for the ninth time this night. She couldn't believe it- both of them had shown animalistic pleasure and bliss the entire night, and only a few hours left until the sun would rise once again.

Soon Yang forgot how many times she has done it and just gave up as she let Ruby continue ravaging her. As soon as Ruby climaxed for the last time up her butt, she laid there, still feeling ready to go. Yang was almost near the point where she literally could not let Ruby out of her, and worried that this might be a problem- she sucked it in and slowly pushed Ruby out of her. Ruby felt herself calm down at last, as her appendage became soft, and slowly shrank down back to her clit.

"It...it finally went down- If you'd..have continued further- I might have been broken beyond repair sis." teased Yang. Ruby blushed and held her sister tight as she began suckling her sister's teat. Yang- after her state of sexual high- remembered one more thing-

"Hey Rubes...could you grab the small case in my shorts? I need to take something."

"But~"

"Please sis~" teased Yang as she kissed her sister's head. Ruby obliged and quickly used her semblance to grab the case. She could smell fruits from just the case alone- making her mouth water. She quickly opened one and took out a yellow pill- it smelled of sweet lemon. She quickly gave it to Yang, who swallowed it immediately.

"So is something supposed to happen Yang?"

"Dunno. Uncle Qrow said to just take the pill. I did, I dunno- maybe it's for pregnancy?

"That can't be it- you just told me a few hours ago you have to take that then wait for it to take effect before...doing this."

"Well, I guess we can ask him at a later date. So- Uh sis...what are you doing?" asked Yang. Ruby was sniffing the air. Yang too sniffed- a new scent appeared amidst the smell of sweat, sex and cookies.

"Why does it smell like strawberries all of a sudden?" asked Ruby all of a sudden. Ruby, with the action of a hound, sniffed for the source and found it. Yang followed, and her gaze widened. Yang's breast had began lactating from the pill. She has a few select words for this phenomena, but couldn't say it out loud. Now when her sister is mouthing at her breasts.

"...Huh. I guess this must be...the pills work? Maybe? Well can't let it go to waste- I don't want to clean it off the floor so Ruby- Go ahead."

Ruby, without another word, quickly suckled her sister, and made Yang moan a bit as the feeling of lactating was new to her. As soon as Ruby had drank from her sister, she felt any remaining hit subside. Ruby took note of her sister's milk- mild tastes of strawberries and possible lemon. She kept drinking from Yang as it was intoxicating to her, as Yang just pat her "Baby Sister" calming her down more. Ruby stopped a mouthful, and kissed Yang, tasting her own milk, with Yang drinking a mouthful. Ruby smiled as she fed Yang, feeling content. She quickly hugged Yang and soon, fell asleep. Yang then remembered a fond memory with Ruby, with the same position as she is in now. Yang now filled with determination(and something else), hugged her sister as they both now fall asleep on the floor.


Yang woke up the next day, in the afternoon with Ruby gone, but found that she was in her bed. She checked further to see that her breasts had bite marks as well as a her tank top now riding over it- she had increased her cup size in the span of a few hours. She checked under the sheets to see that she's only wearing her shorts, and only her shorts. Yang let out a proud chuckle as she searched around and checked a note beside the bed that read:

Yang

Dad left on a small trip for groceries and I decided to accompany him. I've had my breakfast and lunch so I left some food near the bed for you. Also saw the red note from Uncle Qrow you clearly forgot to tell me. I love the gift!

"Heh, still the same energetic sister." Yang looked to her side and noticed the food Ruby had left, and the a pitcher of milk. As Yang got up from the bed, she felt her nipples ride up her now slightly wet tank top began nibbling on the food her sister had left. As she dug down on her food, she felt as if she had a load of her chest- like her breasts were free of something. Yang then wondered why she felt that way before seeing a large pitcher of milk. She smiled as it dawned on her that her sister had milked her dry and the milk on the table was from her. She just chuckled at her baby sister's strange addiction to milk. Even before this, she only drank Milk and water but mostly milk, never soda and juice.

"Ruby you little baby. Still having issues eh?" said Yang as she poured herself her own milk.

"I HEARD THAT!"

Ruby came back in with bags filled with fruit. She quickly dropped them and guzzled down the pitcher she had made. Yang just blushed at her little sister's actions.

"Maybe one day I'll be bigger than you! So I'll keep drinking it! NO. MATTER. WHAT!"

"If you say so~"

"OK now that you are all better- dad wants to talk to us both."

"So Uncle Qrow told him that we slept together in bed right?" said Yang peacefully as she continued eating.

"Why yes he- WHAT!? DAD ALREADY KNOWS!?

"No need to worry sis- I'm sure dad will "eventually" understand-"

"So that explains why he was eyeing me the whole time in the market- as well as cussing out in public on his scroll-"

"I can answer most of the questions you're going to ask me later, AFTER I have my breakfast."

"It might be better to call it linner. It's four in the afternoon."

"Grub time. Can't talk now." said Yang as she dug into her meal.

"Yaaaaaaaaaaaaaaaaaaaaaaaang!"


A/N:

Hi. I'm new. To writing Fanficiton. I'm used to writing stories for doujins in Japan and this is the first time I wrote one. I hope this to be a series. And I need to fiddle around more around the site. I was surprised to hear RWBY was made in the west. That really impressed me. Oh I digress, I need an intro.

Hi. I'm Riek'Roz. A pen name that I just thought would sound foreign in a foreign land. I'm Japanese and I write stories for friends. That is all. Learning English was fun for me.

If this story made you happy, good. Though, I'll be adding more in many many weird ways. I'll also update and make corrections for streamlining purposes. It makes me feel...relaxed. Again new to this.

A/N(3-28-16): I rewrote the entire prologue. I've learned much- or maybe learned little. We'll see. I dunno. I hope it's better than my horrible first attempt.
