Author's Notes: Heyyy there! Another big story that's not dead! How about that? As with M&M's (Mothers and Daughters) this story is far from over and now that I've finished up several of my smaller stories, I'll be able to focus on bigger bad boys like this. Of course there are still other small stories that I know some are waiting for an update, such as "Making up for Missed Birthdays" and "Bumblebee's Pet Bull" among others. Such stories are currently on the back burner as of now while I focus on my larger stories, such as the recently published "Futa Kali Breaks Blake" as that certainly turned out to be a hit with many.

ANYWAY, I would like to remind everyone, I am very much open to critique for this and other stories and new ideas are always welcomed. Finally, as always, I hope y'all enjoy.~

"Y-You want me to…what?" Yang asked, utterly dumbfounded by her sister's request.

"Fuck me Yang, I want your big delicious grimm cock inside me… please.~" Ruby said with a seductive tone Yang was still getting used to.

Yang wasn't going to lie to herself. What Ruby was asking her to do, the way she was asking her to do it, may have actually been the hottest thing she'd ever heard, and with all she's been through recently, that was saying something. All the crazy schemes and sex the blonde's had speaks for themselves… and all the mind breaking of course, that always ended up quite enjoyable for everyone involved.

Speaking of her mind broken pets…

Mercury was doing as he'd been instructed and was eating Neo out as the totally mind broken ice cream girl was jacking off two ursas as her mouth was pleasantly filled and continuously rammed by an eager to cum beowolf.

Similarly, Cinder followed through on her given orders and was happily giving herself to a dozen seers. The tentacled creatures made use of every hole of the formerly proud half maiden had to offer. Due to the natural lubricant on the slimy tendrils, and their just as natural moldability, there was no exageration. Cinder quickly found her pussy utterly filled with nearly a dozen slimy rods, all pushing in and out at ever increasing speeds. Her solid ass also found itself stuffed with at least 8 of such tendrils, many already leaking pre-cum, which only helped the rods slide deeper in and even for more to join. There were also a couple wrapped around Cinder's undeniably bodacious breasts that seemed to just enjoy squeezing the pyromancer's jugs again and again.

However, that wasn't the end of it. Every hole after all, that was Ruby's order, and Cinder had five on her head. Her mouth, easy enough to guess and happy enough to be stuffed to the brim with nearly as many seer cocks, aka their tendrils, many of which were also leaking pre-cum right down the eager slave's throat. Her ears, which again thanks to the tentacle's naturally unholy lubricant, allowed the black slimy rods to slide right in, only two or three at a time. Though with Cinder being so mind broken, so in love with following orders and pleasing her mistress's grimm, they might as well have been fucking her pussy with how good it felt to the slut. Lastly, yes, even her nostrils found themselves at the incredibly pleasurable mercy of the tentacle grimm. While each were only capable of holding one terndral at a time, the feeling of having truly every whole filled with incredibly addicting grimm cock was almost too much pleasure for the mind broken slut to handle… almost. She also had nothing to do but enjoy herself as there was no risk of not getting enough air as the terndrals can make themselves porous enough for air to pass through, meaning that even with her mouth and throat so stuffed, she could still breath and please her grimm masters over and over again.

Now, Glynda, she was also doing as commanded and happily so. She was being held in the air by the Beringal beneath her as it rammed it's cock up into her tight rear. Why the beringal holding her up in the air? Why so that his brethren gorilla grimm could use her other holes as well. There was a beringal in between Glynda's held and spread legs furiously pumping into her ever needier pussy. Meanwhile, there was yet another ape beast using her eager mouth as its cum depository, something she was thrilled to have it used as. After all, per Ruby's commands, Glynda was only allowed to cum once every time she swallowed a load of grimm cum, suffice to say, her upside down face was already drenched in spilled droplets of cum after a few minutes. Of course that only made her enjoy the situation even more.

As for the remaining members of team rwby, Weiss & Blake having been left to their own devices, paired into a 69 position on the forest floor. Both girls had their cunts absolutely brimming with grim cum from all manner of species, some beowolf, some Nuckelavee, and some even Emerald's or one of Yang's grimm clones. Naturally, each girl saw the other's slit as a wonderfully delicious looking meal and both were more than happy to indulge in the other's cum filled cunts. They had been at it for over half an hour, each only licking deeper and deeper into the other's addictive cunt, scooping more and more grimm cum out on their tongues to swallow down. They hadn't been given any new orders as Ruby was delighted to see them participating in 'team training'.

Finally, Emerald, she was a simple unbroken girl and was more than happy to have one alpha beowolf tend to her as it held her up off the ground with her back pressed against a tree as it rammed its massive 7-inch member into her soaking pussy again and again. In the moments lust hadn't completely enveloped her mind, she would look over to see Yang and ensure her mistress's safety. Currently, she watched as her mistress leaned over her sister's naked and leg spread body, one hand on the tree to her sister's back and one gripping her own cock as she angled it towards Ruby's tight little slit. Emerald smiled, happy to see her mistress finally get what shes been after since the beginning. Emerald still felt something was… off, about Ruby, but that could be taken care of another time, the alpha beowolf was about to cum and so was she.

"So... your sure about this Ruby?" Yang asked yet again, wanting more than anything to make sure Ruby felt safe.

"Yaaaaannnnggggg! P-please! I… I already asked… b-but if you want me to say it again then… PLEASE YANG! FUCK ME!" Ruby screamed out in a near childish whine, a far cry from the seductive tone she had earlier. Yang almost questioned such a serious change in tone… almost.

Not wanting to keep the love of her life waiting, Yang thrusted forward with heavy force.

*SWAP* went the sound of skin on skin as Yang managed to thrust forward with enough force to already bottom out her currently 6 inch Grimm cock deep into her little sister's hungry slit.

"AAAAAHHHH!" Both sisters screamed out in unison as the pleasure from such a taboo act was… intense.

Wanting to feel the sensation of running her skin along Ruby's again, Yang pulled her hips back, before quickly thrusting forward once again with matching force.

Of course her pace only increased as she felt hungrier and hungrier for the sensation of pushing herself ever further into her sister's pussy. Yang's muscular body made pushing deeper and deeper into her sister a fairly easy task. Of course it didn't hurt that Ruby had seemed to of already lost her virginity before now.

Though that detracted little from Yang's enjoyment. While she had dreamed of this moment for many years, she always expected it to happen with a strap on rather than with a Grimm-sex-magic-cock and with a lot less Grimm fucking going on in the background, but hey, she wasn't complaining.~

Yang was far too busy focusing on sending her cock as deep and as fast into Ruby as she could. Again and again the sound of flesh slamming against flesh was all that could be heard, that and the moaning of course. Oh how Ruby let out such enticing moans. ~

"Ah! A-ah! Y-Yang! M-More!" Ruby screamed out, sounding so absolutely desperate for more.

Naturally, Yang answered her sister's plea, though not with words. Instead, the blonde stopped moving all together, and took one deep breath. Before Ruby could even ask why she had stopped, the young grimm queen locked her red and black eyes with her sister's silver pair and thrusted herself forward with unbelievable force.

Yang was now fucking her sister hard enough to shake the tree the little redhead had her back against. Not so much grunts came from Yang's lips, more like small roars of an alpha beast as it took its mate.

Ruby now had her legs and arms wrapped around Yang's body so tight, you'd think her life depended on it.

Again and again, Yang fucked Ruby with greater force than either had ever experienced. And one might expect with that in mind, they were already nearing their climax.

"Yang! I-I'm-AH! Mmmm! I'm gonna cum!" Ruby cried out as the sweat that slowly dripped down her body was constantly flung off by the force of Yang's heavy and rapid thrusts into her.

"Mmmmmm! Ah!...mmm...me to Ruby." Yang let out in a low groan as she continued to focus on pumping her hips into her dear sister.

As it would turn out, the sisters weren't the only ones reaching their limit. If the pair were not so engrossed in each other, they'd be able to hear the ever louding moans of the other girls who didn't have their throats filled with grimm cock. Even the beats of darkness themselves that had a body to use were starting to let out louder and louder growls and howls as they used either one of the subs or one of Yang's sexy grimm clones.

And then suddenly, all at once, many roared out in near perfect unison as grimm and girl alike finally reached total ecstasy.

"Aaaaaahhhhhh! Y-Yang! I'm-I'm cumming!" Ruby cried out as her body tighten her lower walls around the warm phallic object still thrusting into her.

"Me too Ruby! I'm cumming-ah! I'm cumming inside you!" Yang roared out as she did just as she said she would and hilted herself deep inside her dearest sister one last time with a force before unloading.

Ruby's adorable little snatch was filled to to the brim and then some as quite a bit of Yang's warm cum started to slide out of the redhead's tightening pussy. Of course, she wasn't the only one getting her fill.

Glynda had finished sucking off yet another beowolf with ot happily sending another load of cum down the mature blonde's eager throat.

"Gulp* Mmmmm! *Gulp* Mmmmmmmm! *Gulp* Mmmmmmmmmm!" Glynda moaned as she swallowed down spurt after spurt of warm and filling grimm cum, sending her into orgasm after overwhelming orgasm.

Similarly, Neo, in a near constant state of orgasm, reached her pleasure peak once again as a load of addictive grimm cum was shot down her own petite and needy throat, causing her to send her own juices into Mercury's mouth as he continued to eat the ice cream girl out.

And similar enough, Wiess and Blake both moaned into each other's snatch as the 69-ing pair had not only swallowed more than enough delicious grimm cum, but with each girl having experienced tongues at this point had also eaten each other out to lovely orgasms.

And of course there was Cinder. As with the others, Cinder's grimm partners had been pushed to orgasm and with the tentacled beasts filling her one of her holes with their wet tendrils… well, when they released their seed into the half-maiden, she was almost literally filled to the brim with grimm cum, her very brain getting a solid dose, only enhancing her addiction for the substance. She was simply and heavenly filled and yet she wanted more, though the overwhelming pleasure that such a filling would bring actually forced her body to pass out from overstimulation. Though that didn't stop the seer's from having another go at her, now limp, body.

Finally, Emerald, she may have had the simplest experience, yet it was no less satisfying. She started to moan out louder and louder into the night sky, matching the growing ferocity of the alpha beowolfs thrusts into her and its own loudaning growls. And suddenly, she let out an orgasmic scream into the night sky just as the alpha let out an intimidating roar and one last powerful thrust into the green haired girl, filling her womb to its utter limit with its cum, some even spilled out and only added to the puddle of sexual fluids beneath the pair.

As quickly as the euphoria overtook them, the screams and pleads for more were reduced to heavy panting breaths from all involved as they came down from their sexual high.

"*huff* *huff* Holy-*huff*- shit…Ruby- *huff* -that was amazing." Yang just managed to get out. Although her Grimm powers have Yang more than exceptional stamina, the current white haired and skinned Grimm queen was feeling quite… human. Though Yang paid it little mind as her red and black eyes looked incredibly lovingly into Ruby beautiful, innocent, silver eyes.

"*huff* Y-yeah *huff* I- *huff* I had no idea it would feel that good. *huff*" Ruby said as she continued to take in the subtle sensation of her pussy still being so utterly filled with Yang's cock and cum.

"Oh what? Didn't expect big sis to make you cum so hard?~" yang teased as she leaned down to bring her face to Ruby's

"Hehe, I don't know.~ I guess I was just hoping you'd at least be… adequate, and very satisfyingly, you were much more than that." Ruby said as she leaned up to meet Yang's face.

Suddenly, their lips were together again, each pressing against the other with a heated force. Their tongues quickly slipping into each other's mouth, first meeting where their lips had met, then pushing onwards to truly taste one another before both coming back to twirl around the other's tongue in a passionate embrace.

Once the incestuous couple separated, Yang was the first to speak.

"Sooooo~... what do you want to do now?"

"Hmm, well I- oh wow, the suns coming up, but I don't even feel tired and I didn't sleep at all!"

"Oh that's because of my cum dear sister.~ not only can it be addictive and as with Neo, it can replace the need for food and water. It also restores your energy after it gets absorbed by the body. Meaning, as again with that little Grimm cum addicted ice cream girl over there, we could literally go at it all day and night with me or the Grimm. Just so you know.~"

"Oh, cool! As for what we should do today? Hmm… how about-"

"Pyrrha!"

"Hm? Oh hello there Yang! How can I help you?" Pyrrha said with her usual welcoming tone.

The two were in the academy's weight lifting section of the gym. Yang had heard Pyrrha was her, as she often was, and decided that it was the perfect place for them to be alone and have their chat.

"Oh… well… I was hoping to talk to you about something… something serious." Yang said in an unusually serious tone.

"Oh?" Pyrrha simply stated as she set down the pair of dumbbells she had been using, her body already dripping in sweat and Yang nearly doing the same as she looked over the incredibly fit fellow huntress in training.

"Uh.. Uh-Yeah! You see Ruby has… fallen, for someone, you know?"

"Oh. Yes, I can imagine." Pyrhha said in an uncharacteristically uncaring tone, one might even call it an angry one.

Which of course it was. Pyrrha had seen how Ruby had spoken with HER Jaune. The younger redhead had practically flaunted her body to the blonde knight in an attempt to seduce him, at least that's how Pyrrha saw it.

"Great! But the thing is… I don't think she should be with this person. I know I started younger, but my little Rubes is just not ready for something like this… aaaand I'm pretty sure who she's interested is already taken and-"

"Yes! He is!" Pyrrha shouted out suddenly, her green eyes going ferocious

"I-I mean your right Yang! She's far too young for such a thing. She's just not ready and she should be stopped before it's too late!"

"Uh… yeah, exactly. So, what I plan to do, is prank her. Prank her so bad she won't ever want to date any of the boys at Beacon. It'll be harsh, she might even cry, but it'll be a lesson she needs, though I understand if you don't want to-"

"I'll gladly help! I-I mean it'll be a valuable lesson! If she cries… oh well, lesson learned!" Pyrrha said with a smile.

While the redhead was falling into place even better than the sisters could have hoped for, Yang found herself just barely resisting putting her fist to the green eyed girl's face. The way Pyrrha seemed so giddy about hurting Ruby was beyond infuriating. The idea that Pyrrha might have done something like this on her own crossed Yang's mind and ensured the blonde would feel little remorse for how they would be treating the amazonian girl.

"Well… alright then. Meet me in the Emerald forest just before the Sun fully sets. Just head out straight from our dorm's secondary exit and head straight, that should lead you to a clearing and where we'll… have some fun."

"Wonderful! I'll see you then! Oh! I just can't wait!" Pyrrha squealed with joy. The thought of Ruby never speaking to Jaune again just made her too happy to fake any other emotion.

Feeling herself unable to resist releasing her anger onto the redhead before for much longer, Yang immediately turns and leaves. Due to Yang's quick pace and Pyrrha being so distracted by her own 'happy thoughts' the redhead just missed the sight of Yang's eyes going a deep blood red. Though it was a sight she'd see very soon.

Author's Final Notes: And there we go! A healthy dose of Ruby getting filled by her futa sister and a solid teasing of whats to cum.~
