Forbidden Volume Chapter 2
Sister Shenanigans

(Part 2 of Coupled Quartet)

-RWBY-

Yang managed to get into the quartet of wives' bedroom, where she had to hold back the urge to both let out a joyful squeal and a groan of sexual frustration.

Her beautiful wife and baby sister was back, which was wonderful by itself, but just like that, the mere presence of the silver eyed woman had made her already jerked dick harder than a Grimm's bone armor.

And if she hadn't moved a little faster, her sister would have walked in on her stark naked on the couch. Granted, they had been in wedded bliss near three years now and been as intimate as incestuous sisters could be, but that still didn't mean that she wanted to upset her sister by being such a blonde bimbo. That was reserved for special occasions.

"Stupid boner, one of these day's I'll have to put a leash on you" she quipped to the throbbing rod between her legs as she looked between her abundant cleavage.

"Gah, how am I going to go out there without Ruby noticing? She's a little scatterbrained sure, but she's not stupid. And besides, I don't think she'd really mind... but I don't want to do this without some foreplay."

Then Yang remembered something. She went over to her personal section of the chest of drawers they shared and pulled out a long rectangular box.

Pulling the lid off the paper box, she smiled bashfully at the outfit. It was made to her measurements, just as Blake and Weiss had asked the tailors. It looked at first like your stereotypical maid uniform.

Of course, this was far from that.

The 'bodice' of the outfit was so low cut in the front that, as Yang put it on, she could do nothing but watch as her ample breasts bounced freely just above the ultra-lacy window that framed them.

As for the 'skirt', well, it was so short as to barely cover her bottom or crotch, and if she bent so much as the tinest bit forward or back, the frilly lace trim at the bottom would effortlessly ride up the side she leaned towards, giving any potential viewer an unobstructed view.

Cap all of that off with white thigh high stockings with black garters and matching garter belts, along with matching bicep length gloves, and Yang looked the perfect image of a fetish maid ripped out of an erotic dream.

And as for any undergarments, the outfit came with none, leaving her going commando. Yang supposed she could put a pair on, but she thought better of it. At this rate it would just cram herself into a vastly uncomfortable space.

She elected for the time being just to tuck her unwavering erection into the band of her skirt, leaving her balls dangling just above the bottom of the skirts frilly edge.

Yang noted, with a minor blush and giggle that, if she walked fast enough, the speed of her walking might make them slap against her thighs in a very erotic bit of percussion.

"OK, deep breath Yang Xiao Long-Schnee-Belladonna-Rose, time to surprise your lovely sister and beloved wife~!"

~o~

"Oh man, why did I have to pop a stiffie now?! I wasn't even thinking of Yang's bootie... ok yes I was, but still!"

Zwei, sitting on his doggy bed let out a reassuring bark. Ruby smiled at him, "Thanks Zwei, I'll be ok. You go ahead and get some sleep." Zwei, ever the clever dog, barked affirmative and proceeded to lay on his side adorably, Ruby coming over to pet the tired dog lovingly as he swiftly fell asleep. "Good boy" she lauded to him, tiptoeing out of the living room and into the kitchen.

As she stepped into the kitchen, Ruby huffed as she felt herself rub against the fabric of her panties. She was in multiple senses not as gifted as Yang, but as her wives often said, that was certainly not a problem whatsoever, since her smaller frame kept her assets perfectly proportioned, and just right for her nessecity of high speed.

That being said, she was proud that she had developed very nicely, a firm, full bust sitting on her chest, a round, heart shaped bottom that drove her beloveds absolutely nuts, and of course, as she affectionately referred to it, her 'concealed weapon' that was more than big enough to do the job when called for.

She just wished that the 'barrel' of her special gun didn't get so tricky to conceal sometimes.

And yes, childish though it may be, Ruby found it hard to refer to it without code words, since, to her knowledge, her and Yang were the only girls from Patch packing heat, so she had learned early on to be... discreet.

That said, Ruby was glad she hadn't really had to deal with it being a problem until... after her second year at Beacon.

It was by then that team RWBY had secretly started dating each other at once, unbeknownst to anyone but a select few professors, whom decided to keep their secret, as they saw such a rare form of love between teammates as a wonderful thing.

With the her then girlfriends and now wives, Ruby had been able to, tend to her sudden onset of desires in something of a controlled environment, and the three of them were more than happy to reciprocate, Yang even teaching Ruby some much needed tips on how to keep it in your skirt, both literally and figuratively.

As Ruby thought back on this, she heard footsteps coming down the hall, "Yang? Is that you?" "Yep, be out in a minute honey~" came a singsong voice. Ruby arched a red-tinted black eyebrow, but shrugged her shoulder as she grabbed a raw strawberry and started to nibble the savory fruit. "K."

As Yang stepped in, Ruby started to speak "How was your d-" she was floored when she saw her sister, her beloved, beautiful, inhumanly wonderful wife, in this pure sex dream of an outfit come to life.

"How may I serve you, mistress~?" Yang said in a voice that let Ruby know immediately that Yang was totally in control, despite the words she had used. Well, that and the predatory smile she had across her lips.

"U-u-u I don't-"

"Aw, Mistress, are you coming down with a case of the stutters? Here, let your dear maid Yang take care of that."

And without a moment's hesitation, Yang closed the gap, and locked her beloved in a kiss that rivaled her own internal fire.

As if to stoke Ruby's own furnace, Yang's gloved right hand went under Ruby's skirt and began massaging the outline of Ruby's shaft through her panties.

Ruby moaned into Yang's mouth and instinctively rolled her hips towards her sister's hand, wrapping her arms around her sister's neck, throwing any and all caution to the wind as she decided to enjoy the surprise.

Ruby moaned louder into the kiss as she was rubbed through her panties, humping her sister's hand as her face flushed unashamedly.

When the two finally broke the kiss, Yang smiled and whispered, "Would mistress enjoy... direct contact?"

Ruby nodded emphatically, making Yang break out into a full blown grin as she knelt, pulling down Ruby's panties and unbuckling her skirt, leaving the younger dick bearing girl bottomless from the hips down.

The more slender erection was indeed at full mast, throbbing and already leaking pre-cum from the tip, Yang kissing the fluid from the end, making a shiver reverberate throughout Ruby's body.

Yang's own erection neared a foot in length with an inch and a half thickness, Ruby's was no less impressive despite it's more compact nature, a full nine inches and nearly an entire inch thick, and they were both positively throbbing.

And the moment Yang saw that rod of flesh from between her sister's legs, she immediately took her breasts and wedged Ruby's penis lovingly between what her wives affectionately called her 'chest pillows'.

Ruby looked down at Yang with a cute smile, blushing madly as she bit her lip, trying her hardest not to hump too hard against Yang, knowing that if she did she would risk jabbing Yang in the face. Horny and all too eager, she still wanted to make this just as enjoyable for Yang as it was for her, a thought that came from so long as both a team leader and sibling.

Ruby whimpered as she felt an orgasm began to stampede through her, Yang noting with delight as she felt the surging blood flow, knowing her dear Grimm Reaper would soon be covering her face and chest with that hot spunk she loved so much.

And indeed, Ruby let loose with a veritable volley all over the blonde bruiser's face and chest, painting her tanned skin with splashes of white.

Ruby's knees shortly gave out, but Yang was able to catch her in the nick of time, holding her sister-wife in the traditional bridal style, one arm behind Ruby's shoulders, the other under the knees.

"It's ok Mistress, Yang's got you" she confided as she kissed her sister on the lips, letting Ruby taste a little of herself that still lingered there.

"Y-yang" Ruby barely managed to squeak out, "Yes, mistress?" Yang replied.

"Please take me to bed, I really need you to take me, please"

Yang understood the double meaning right away. "Of course."

Yang was gentle and delicate as she carried Ruby through their home to the bed, laying her down and helping the blushing rose undress, until she was bare on the bed spread.

Yang herself stripped until she was in naught but her Stockings, garters and the associated belts, and the gloves.

She then shuffled onto the bed, kissed her beloved sister, and plunged her long, throbbing length into her fully in a fell swoop.

Her curtain of golden locks hung over them like a wave of sunshine, and as she plunged in and out, resplendent silver met royal purple, nothing between them but unabashed, unrestrained love.

Their voices cried out for each other over and over, their hands finding each other's bodies, Ruby's nails digging into Yang's back, Yang's hands fisting the sheets beside her beloved sister-wife's head.

The blonde felt Ruby's semi hard dick flop between them with each thrust, Ruby letting herself be at Yang's total mercy.

"Ya-ya-yang! I'm gonna-gonna!" "Me too!"

They both cried out as they simultaneously grabbed the other in a passionate hug and kissed with fever-like passion, both of their Semblances kicking in out of instinct, Ruby's hips firing at high speed and Yang's eyes glowing like molten lava as her hair lit up the room. The two orgasmed at once, utterly exhausting themselves in the process with the ferocity of their passions.

Were it not for the fact that the two also passed out in that exact moment of orgasmic bliss, they would have heard the door close and a pair of voices announce "We're home!"

Blake then sniffed the air and blushed, her ears turning backwards and flattening against her head in bashful embarrassment. "Um... wow."

"Is something wrong, sweetheart?"

"Ruby and Yang seem to have... gotten carried away" Blake said as diplomatically as she could, Weiss letting out a sigh as she understood. "Typical. Well, I guess we'll just have to have our own fun tonight, won't we my little kitten?"

"Absolutely, my wonderful Snow Queen."

But that, is a story for another time.
