Just Not Fair (RWBY)

Commission

Themes: Cheating, Corruption, Humiliation

Summary: Ruby and Yang receive a package from their moms. Summer and Raven have been on vacation for the past week, so what sort of trouble have they gotten into?

-x-X-x-

“Ugh, I need a new bra… again.”
 
Yang Xiao Long doesn’t usually make a habit of ogling her baby sister when she’s getting dressed, but a comment like that forces her to glance over. Admittedly, Ruby hasn’t been Yang’s baby sister for a long time now, not really. By the time they’d graduated Beacon, Yang had stopped growing a while before. Ruby though… Ruby hadn’t.
 
She might have been the shortie of Team RWBY back in the day, but unlike Weiss, Ruby actually had a good excuse… namely, she was years younger then all of them. With time to grow and mature, Ruby had actually sprouted into a true woman… one with bigger tits than Yang, annoyingly enough.
 
Just as she’s about to make some pithy comment about Ruby’s massive cow udders however, there’s a knock at the door and Yang feels a flush of shame that she had been about to take out her own feelings of inadequacy on her younger sister. Even if Ruby wasn’t the baby anymore, even if she couldn’t be described as ‘little’ by any stretch of the imagination, she was still Yang’s sibling.
 
“I’ll get it!”
 
Hopping up from her seat, Yang goes to the door only to find a package waiting instead of a person. The delivery guy hadn’t even stuck around to make sure she got her mail… but whatever. Looking at the return address, Yang’s eyes light up and she quickly picks up the package and brings it inside.
 
“Ruby! It’s from our moms!”
 
A happy squeal comes from the other room and Ruby comes bounding in, her currently braless breasts bouncing within the confines of the t-shirt she’s hastily put on. Yang does her best to ignore that though as they open up the package and find a video message along with a box of Summer Rose’s fantastic cookies.
 
In short order, the two sisters are sitting down on a couch, playing the video on their big screen TV and chowing down on the cookies.
 
“Mmm, these are shoooo good! Mom really outdid herself!”
 
As Ruby moans in delight, Yang has to admit that her sister is right. The cookies are absolutely amazing. Meanwhile, the video starts up and shows both of their mothers on the screen. Raven Branwen and Summer Rose are both absolutely gorgeous in their bikinis. Both are also much more buxom than their daughters, making Yang feel even dumber for her initial feelings of inadequacy earlier.
 
“Hi girls!”
 
The two older women wave at Yang and Ruby. Summer is wearing a red bikini and Raven is wearing black. Both also have lipstick on, Yang notices. Purple for Summer and black for Raven. Weird, but not too strange.
 
“We’ve really been enjoying our vacation so far, girls!”
 
“That’s right… and we have something to tell you about that!”
 
“We’ve met someone new!”
 
Wait, what?”
 
Both Summer and Raven are beaming into the camera, even as Yang and Ruby freeze up on the couch in abject confusion. Giggling girlishly, Summer shrugs her shoulders, causing her bosom to bounce.
 
“I’ve already sent Tai the divorce papers I’m afraid, so don’t feel like you can try to talk me out of this, girls.”
 
Raven nods, before lifting the camera up into the air.
 
“That’s right. Tai was fine… but we’ve met a REAL man while we were out here. Someone who treats us right.”
 
“And by right, she means oh so deliciously wrong~”
 
It’s like watching a train crash in real time, Yang can’t help feeling. She’s horrified, but she can’t look away as the two MILFs carry the camera inside and reveal just who their brand new lover, the man that Summer is divorcing her husband for, actually is.
 
“Ah. Hey girls, welcome back.”
 
“Hello stud!”
 
“Mm, I know it was only a few minutes, but I already missed you Loverboy~”
 
Cardin Winchester grins at both Summer and Raven before winking at the camera. Yang just gapes in horror, not entirely sure what she’s even witnessing. How could this happen? WHAT was even happening?!
 
Unfortunately, she gets an answer to the second question before the first as both Summer and Raven waste no time in throwing themselves at him. One holds the camera while the other kisses Cardin in a lover’s embrace, making sure that Yang and Ruby both get a detailed view of each kiss and the way their mothers’ bikini clad bodies press against Cardin’s chiseled, bare-chested form. Not to mention a ‘nice’ view of his hands moving all over Summer and Raven’s asses, groping and squeezing them while they kiss him to his heart’s content.
 
Finally, the two MILFS sit down on either side of Cardin with Raven holding the camera out in front of them all.
 
“We know that this might be a little weird for you both since Cardin went to Beacon with you.”
 
“But we don’t care! Cardin is your new daddy now brats, so get used to it!”
 
“Raven…”
 
Summer’s reproachful tone makes Raven blush and avert her eyes, surprisingly enough. But Cardin just laughs… and then they get right into it. He grabs Summer and pushes her onto her back, ripping her bikini off almost contemptuously as Ruby’s mother squeals in delight. Then, he fucks her. Just like that. No fanfare, no hesitation… just Cardin Winchester’s cock buried in Summer Rose’s twat.
 
Yang knows she should be looking away. No, she should have shut off the video by now. And yet… she can’t stop watching. She’s staring at the screen in horror but also fascination, her lilac eyes wide with disbelief. This couldn’t really be happening, right? Cardin Winchester couldn’t have somehow ensnared their mothers in some sort of three way love scheme… could he?
 
But it gets worse. Because while neither Summer nor Cardin pay Raven much mind while he’s fucking Ruby’s mom, once he’s finished inside of Summer, things escalate. Raven squeaks as Cardin yanks her onto her hands and knees and Summer giggles as she takes the camera from her MILF counterpart.
 
“Your turn, Raven. Though honestly, you barely deserve one~”
 
Those words coming from Cardin Winchester would have infuriated Yang… but at least they would have made sense. However, they DIDN’T come from Cardin. No, they came from Summer… and she doesn’t stop there. Ruby’s mother proceeds to mock and belittle Raven the entire time that Cardin is fucking her doggystyle.
 
She calls Raven’s tits puny, despite them being bigger than Yang’s. She brags about how Tai had even told Summer that her pussy was tighter and that she was so much hotter than Raven. And Cardin… Cardin backs it up, agreeing that Summer IS the better lay even as he fucks Raven, pounding into her from behind just as hard and fast as he’d plowed Summer in that mating press.
 
“You’re so pathetic Raven! Even my own daughter has bigger tits than you!”
 
Yang blushes hard at that, as Summer brings up the very thing Yang had been feeling inadequate about just a little while ago. It’s worse than she’d thought. Summer and Raven haven’t just somehow fallen for Cardin’s complete lack of charm and charisma. They haven’t just been seduced by the Beacon School Bully in spectacular, incomprehensible fashion.
 
That would all be bad enough, but more than that… the worst part is seeing her own mother Raven is on the bottom of the totem pole and… and LOVING it. Raven had always been a little rough around her edges as a mother. In fact, Uncle Qrow had once confided in Yang that he’d had to force his sister to stick around and not go running off to become some sort of Bandit Queen.
 
But she’d at least always been there for Yang. She wasn’t winning any mother of the year awards, but that was only because her competition was the oh-so-perfect Summer Rose. Still… she was enjoying being dominated by both Cardin and Summer. It was obvious from the expression on her face as her eyes rolled up in her head and her tongue lolled out of her mouth.
 
Cardin finally cums inside of Raven. He creampies Yang’s mother just like he did Summer. Then… then the video suddenly jump cuts from the bedroom to the kitchen, where Yang and Ruby watch as Summer bakes a fresh batch of her oh-so-delicious cookies. When Yang glances to the box, her eyes widen as she realizes Ruby has kept eating them throughout this entire time.
 
Yang had only had one cookie before the sights on the screen had frozen her in place but Ruby had suffered no such issues. While her silver eyes HAD been fixed on the screen the entire time… she’d been busy devouring the entire box of cookies all the same.
 
“BITCH! GET OVER HERE!”
 
Onto screen comes Raven Branwen… and much to Yang’s horror, her naked mother crouches over the cookie dough that Summer has made with her hands laced behind her head. Slowly, Cardin’s seed discharges from Raven’s cream-filled twat, his cum slopping down out of her and into the bowl until Summer smacks Raven’s ass and sends her away. Then, giving the camera a wink, Summer goes right back to baking… using Cardin’s semen as a main ingredient.
 
As Yang and Ruby both realize what they’ve been eating, Yang expects Ruby to be as disgusted and horrified as she currently is. But when she looks at her younger sister, the look in Ruby’s silver eyes is… is something else. Disdain, she realizes.
 
“Wow, I never noticed how small your mom’s tits were before, Yang. But you… you really take the cake, don’t you? The tiniest tits in our family.”
 
Yang blushes and scowls at that. While it’s true she’s got the smallest rack between her, Ruby, and their mothers, that doesn’t mean anything! She’s still fairly large on average! But before she can muster up a response, Ruby grabs her own tits and smirks, playing with them right in front of Yang and clearly reveling in her bigger rack.
 
Yang’s defiance dies on her lips as she stares at this sight, having never seen Ruby be so… forward and aggressive and domineering before. She can’t stop it when the whimper comes from her lips a moment later. Ruby, sensing weakness, pounces on the spot. Literally too, as she practically leaps across the couch and pushes Yang down, pinning her and kissing her right there on the spot.
 
The taste of cum cookies is still all over Ruby’s tongue as she forces it into Yang’s mouth and dominates her. Yang squirms but doesn’t really fight back. She’s not sure why. She’s not sure what about this situation has her so helplessly turned on. She should be running for the hills. This is her sister! Those are their mothers! That’s CARDIN FUCKING WINCHESTER!
 
But instead, Yang just squirms and wiggles beneath Ruby without truly trying to fight her off. And Ruby just kisses her to her heart’s content before eventually pulling back with a satisfied, knowing look on her face.
 
“Like mother, like daughter.”
 
Yang flushes… because Ruby is right. In the end, she talked a big game but had discovered she liked being dominated by another, larger breasted woman. Just like Raven Branwen.
 
Though, there’s a question of whether Ruby was talking about Yang or herself, because the next thing her sister does is grab her scroll and place a call. A moment later and Summer’s voice comes through in real time.
 
“Mmm, hey baby… you, ah, get that package we, nngh, set you?”
 
“We did mom. Are you fucking Cardin right now?”
 
“Yesssss~”
 
“Great! Yang and I will be there tonight!”
 
“Okay, see you, oooh, soon!”
 
Yang’s eyes are wide as Ruby hangs up the phone. But one look from her silver-eyed sister and Yang knows she’s not going to say no. They will go to Summer, Raven, and Cardin. And Yang and her mom are going to be the bottom sluts of Cardin’s new harem. She’s scared… but she’s also hopelessly turned on.
