Yang burst through the front door of the house, visibly steaming from more than one kind of frustration. Weiss stood her up on their date because of some 'business arrangement,' which to Yang probably meant that her at this point nominal girlfriend was fucking some intern in her office. That would probably be the fourth one that very week, Yang thought to herself as she marched into the kitchen to retrieve the strongest drink possible she could steal from Qrow's stash.
Having heard the crashing door, Ruby got up and stretched in her comfy pajamas before immediately heading to the kitchen to find Yang rummaging through cabinets. "Back already? I'm assuming either it was a really quick date, or something bad happened."
"Weiss is a fucking lying slut, and none of the guys at the bar looked hot enough to get proper revenge on her with. What's new with you?" Yang spat with uncharacteristic anger while she popped the tab off of some vintage-looking beer.
"I beat the last boss of the video game I was playing today!" Ruby said with her usual bubbly words as she walked over and yanked the drink out of the girl's hands. "Don't do that, I don't think it'll make things better. Especially in the morning. And are you sure you want to be talking about Weiss like that?"
Yang tried to snatch the can back, only to be bested by her little sis's super speed. "Of course I do, I'm sure she's saying worse about me-"
"You and I both know that isn't true. Now why don't you come back and play some games with me." Ruby said as she put the bottle back and started pulling Yang towards the living room, her pants sagging slightly on her small frame, revealing a small hint of her panties underneath.
Yang shook her head. Nuh uh, no way was she going there. Don't even try it, horny brain. "Fine, what are we playing? Sweaty Smackdown: Wrestler's Edition?"
"Whatever helps you take your anger out…preferably without destroying the controller." Ruby said as she sat down and plugged in a second, leaning forward on her knees to do so, her butt pointed towards Yang.
Yang bit her cheek. Nuh uh, stop that, brain. No way. Just go to your empty, dark, lonely room and masturbate to the same old boring porn like you do every night. No need to get risky. "C'mon, I thought you loved that game. Aren't you a total, like, weapon's fetishist?"
"That's…not how I would've put it, but okay." Ruby said, oblivious to her sister's thoughts as she started the game and handed a controller over. "And I do like it, even if some of the characters are…kind of weird?"
"Oh c'mon," Yang chuckled. "I'm sure that Ultimate Huntress is right up your alley~" Yang teased her sister, fondly remembering the time she walked in on Ruby humping her pillow while watching the character selection screen a bit too closely.
The same thought flashed through the girl's mind, and her cheeks flushed. "A-are you…ever gonna like, I don't know…delete that from your memory?" The girl asked, yet at the same time, she did indeed select said character.
"Oh c'mon, it's adorable~" Yang teased even as she herself blushed. "Besides, the first time I ever put three fingers in myself was while thinking of Emily Endbringer." she casually added while selecting that very same character.
"Y-YANG!" Ruby said as she turned to face her sister.
Yang chuckled and leaped from a sitting position onto the couch. "Oh c'mon, it's way easier than you think. And more fun~"
"C-can we just…this isn't a topic I'd like to speak about with my sister!" Ruby said as she started the game.
Yang sighed as the game started up, two hot girls in the middle of the ring, ready to destroy body, mind, and clothes in front of tens of thousands of adoring fans. It was like 3/4s of all of Yang's fetishes and she didn't have to feel guilty for playing it around family! "Alright fine, how was your date with Penny?"
Ruby didn't immediately answer as she thought about how the girl continued to ask Ruby if she could see her naked because she'd read that that's what couples do together. "It was…fine. A little chaotic, but that comes with dating someone like her."
Yang grunted and executed one of her character's signatures moves; the Bra Removal. "She's a sweet girl, I'm glad you can spend time with her-" she told her sister while also vividly imagining Weiss riding some pale econ major's scrawny dick.
"And whatever happened with Weiss, I'm sure it's not a big deal." Ruby said as she felt a shudder run down her spine as her character now attacked with only one arm, using the other to cover her voluptuous chest, which visibly jiggled with every movement.
Yang bit the inside of her cheek to keep from laughing. "Yeah, I'm sure," she replied, looking down at her sister only to see that, from her angle, she could look clear down into the front of her pajama shirt. Not only that, but did Yang know prior to this that her little sister wasn't wearing a bra? She didn't, but now she did. That was nice.
With Yang distracted, Ruby was able to finish her off by stripping her down to nothing with a special combo that left the girl cheering. She jumped up to do so, leaving the chest that Yang had been staring at to jiggle a bit just like the character in game that was now nude, if covered by her hands. "Ha!"
Her character and Yang had one thing in common; extremely red faces and expressions of complete defeat. "That's…that's a cheap move," Yang replied.
"Hey it works!" Ruby said as she turned to Yang, then frowned. "Hey, are you okay? Your face is all red." Ruby walked up to the girl and got close, very close, as she put her hand to her sister's forehead. "You're…kind of hot."
"I AM FINE!" Yang suddenly exploded as she leapt from one couch cushion to the other, away from her sister. "J-just…new round! New round!"
"Um…o-okay." Ruby said as she sat down and started another round.
As they got into the swing of things, Yang almost fully recovered from the sheer bolt of sexual energy she got from what amounted to half a headpat. She truly was pathetic, wasn't she? Still, she had a few dirty tricks of her own~
"Oh so you can use moves like that?" Ruby said as Yang used a combo that left her character on the ground, left spread eagle as Yang's character proudly held her character's panties for the crowd.
"Yup, I can also do this!" Yang shouted before suddenly reaching her legs out and wrapping them around Ruby's head, smothering the girl in her muscular thighs.
Ruby immediately felt several sensations run through her body. Horror, embarrassment, shock, and…annoyingly, arousal. She nearly dropped the controller as her character was swiftly stripped and defeated. "Y-Y-YANG!"
Yang released her sister and cackled again. "I learned that one from Blake, hehe~"
"That's so…inappropriate!" Ruby pouted.
"Sis, that's not even lewd where I come from~" Yang retaliated with a wink. "Wanna settle it with one last match?"
"Yes!" Ruby said as she started another round, but now the image was in her head. Did she use those thighs on Weiss? Why did she almost feel…jealous? Either way, she forced herself to concentrate as their battle started, and neither of them spoke for almost a minute. However, as Ruby was finding herself beginning to lose, she decided to take drastic measures. With a huff, she stood up, walked over, and planted herself in Yang's lap, leaning against her, until she felt her sister's pillowy breasts against her back, which while it left Ruby feeling flushed again, it quickly showed a stronger effect on Yang.
Yang bit the inside of her cheek as her mind raced. She knew one move she could do to turn this around, but would she? Could she? She quickly tossed the controller into the air, leaned back, and yanked her top off, before catching the controller once more and leaning forward to press her bare chest into her little sister's back. Hell yeah she could!
This time, Ruby did drop the controller, as with how thin her shirt was, she could easily feel Yang's bare breasts against her, her nipples, rock hard, scraping her fabric, yet it felt like her skin, and she trembled against her sister's body as Yang snatched the victory in only a single move.
"Told you~" Yang whispered in her little sister's ear.
Ruby felt like she wasn't able to move as she continued to tremble against Yang, her breathing becoming ragged as she was most definitely turned on.
Yang found her earlier resistance melting away a bit too as she couldn't resist hugging her little sister around the stomach, pulling her that much closer. "What's the matter, sis~?"
"Y-your…your boobs…against…me…" Ruby nearly moaned.
"What, these~?" Yang whispered as she rubbed her chest up and down her sister's back. "C'mon, I know they're great, tell me more~"
"Wh-what are you doing?!" Ruby demanded, yet still didn't move, and she clamped a hand over her mouth to stop a moan from coming out.
"I should ask you the same thing~" Yang replied, gently tracing her hand down until it was in between her own little sister's legs, gently pressing one finger against her pajama pants and feeling the slightest bit of wetness seeping through. "You seem so horny right now, as if you're turned on by your own big sister~"
That finally caused Ruby to leap off of Yang and turn around, but that didn't help the situation, as her eyes immediately shot to Yang's chest, something she hadn't seen since they'd bathed together as children. "Holy-!"
Yang gulped in the face of such sudden action, but she smirked again when she saw how laser-focused Ruby was on her tits. She pressed her arms together to push them out and swayed a bit, putting on the beginnings of a real show for her. "Wow, you're almost as bad as Weiss is about these things~"
"I…this is…" Ruby shook her head and tried to force her eyes away. "This is…wrong."
Yang leaned forward and cupped her little sister's head with her hand, turning her back until they were staring into each other's eyes. "C'mon sis, you know you like it~"
"I…shouldn't…that's the problem…" Ruby said as her eyes began to wander again.
Yang leaned even further forward until they were almost hanging off the couch, then she used that position to put her hand behind Ruby's head and pull her forward again until their faces were touching. "But you do, and don't you want to do something about it~?"
"I…don't know…" Ruby said with a gulp, her hands twitching as they slowly started raising up towards her sister's breasts.
"Penny doesn't have to know~" Yang teased as her hand reached down to rest over Ruby's chest. "I can show you things she can't even think of~"
"You're still…my sister…" Ruby said breathlessly, as her hands grazed the bottom of the girl's breasts.
"That just makes it extra special~" Yang asserted before pulling Ruby into a deep kiss.
Immediately, Ruby tried to push her away, but instead, her hands found purchase on Yang's chest, and Ruby felt like she was melting as she reflexively squeezed them, surprised at how soft and warm her sister's lips were.
Yang moaned into her sister's mouth as she quickly got to work, skillfully sliding her tongue into Ruby's mouth and exploring with it as she groped her little sister through her shirt.
This was wrong. So wrong. But…something about that almost seemed to make it better. The smaller girl's hands roamed her sister's chest, rubbing the hard nubs of her nipples with her thumbs as her other fingers pressed into her soft flesh, her tits too large for her to grasp all at once.
All too quickly, Yang pulled out of the kiss and pulled Ruby away from her chest. "See, it's worth it, isn't it~?"
"Uuuuuu…" Ruby groaned as she felt like she was about to fall over, having to sit on the couch to recover.
"If you want more, you have to do what I say, okay~?"
Ruby, her face a deep crimson, turned her head away, but nodded.
"Stand up," Yang demanded as she flopped back onto the couch and spread her legs.
Ruby did as she said, quickly noticing how wet Yang was, even through her shorts.
"Turn around, bend over, and take your pants off~" Yang almost purred as she jammed a hand into her shorts.
Ruby shuddered. Normally she would've been disgusted to hear those words out of her sister's mouth, but now…something about it all was…enticing. How she was being ordered to do it, how she was doing it for her sister…it turned her on more than she would've ever wanted or expected. So she turned around, and as she slid her hands into the waistband of her pajama pants, she pushed them down, and bent her body forward. Her ass pushed against the fabric of her black panties as they were revealed in all their glory, the pants falling down her thighs, to her knees, then ankles, then finally, kicked off her feet. From this position, it was even more clear how wet Ruby was.
Even as her older sister rubbed her clit to the sight, Yang still found the ability to reach forward and harshly grope her little sister's ass. "Wow, I can see why Penny is always staring down here when you two are together, you have quite the ass Ruby~"
"Mmmm~!" Was Ruby's response as her mind had the clashing ideals within it, one who screamed at her not to do this, where the other screamed at her to tell Yang to keep going.
"Hmm," Yang wondered out loud as she leaned back. "Now turn around and take off your shirt~"
Ruby quickly flipped around and stared hard at her sister, originally ready to protest, as it would completely expose her breasts, but as she stared at Yang masturbating, her resolve melted. In one swift motion she grabbed the bottom of her shirt and lifted it up and off, tossing it aside as her modest breasts swayed and jiggled. Once she had it off, she turned away her head again, though continued to glance at Yang.
Yang couldn't believe how much of a 180 this night had managed to take. She went from being the most cucked Huntress at Beacon to being within grabbing distance of her own little sister, who was wearing nothing but panties, a blush on her face, and a clear desire to be completely and utterly submissive to someone who wasn't her girlfriend. "You look so pretty, I'm surprised more people aren't falling over themselves to see you like this~"
"Y-you'd be surprised…" Ruby said quietly. "Wh-what now?" She unintentionally squeezed her breasts together with her arms shyly, accentuating them further.
"The panties, duh," Yang said as she pressed down a little too harshly on her own clit, causing her to let out a breathing groan.
Ruby nodded as she hooked her thumbs into the waistband of the panties and, with a deep breath, brought them down to her ankles and stepped out of them. Her initial reflex was to cover herself, but she resisted, and stood completely naked before her sister, her bare, shaven pussy now on display along with everything else.
Yang chuckled as she reached down to take her Scroll out of her pocket, quickly opening the camera and centering it on her sister. "Pose for the camera~!"
"YANG!" Ruby cried as she quickly covered herself.
Yang pouted. "Oh c'mon, I'm safe. You have no idea how many of your friends are on here."
"I…then…can I have pictures of you, too?" Ruby asked, her tone coming off more desperate than she intended.
"If you're a good girl~" Yang purred again. "Now, for your first pose, spread your arms and legs and say 'Penny!'"
"Nnnnng…" Ruby groaned, and then sighed. With a deep breath once more, she leapt out, almost as if she was doing a jumping jack, and shouted, "PENNY!"
Yang quickly snapped a few photos as she started rubbing her legs together. "Now, turn around and bend over again. I intend to have plenty of pictures of my little sister's ass on here~"
Ruby did as she said, feeling juices leaking down her legs as her body trembled with need. She wanted to masturbate so hard, and it took everything she had to resist as she pushed her ass out.
"How about I take a video here~" Yang said after snapping a few photos. "Show the camera what it looks like when Ruby Rose touches herself~"
"I…will do whatever you want me to…" Ruby said between pants as she couldn't help but gingerly touch herself.
Yang quickly hit the record button on her Scroll and zoomed out a bit so it got the full image of Ruby bent over, legs spread, gently touching her dripping cunt. "So be nice and tell the camera, sis, why are you touching yourself right now~?"
"My…my sister is making me do lewd stuff…and it's turning me on…making me—ahhhhh~—go crazy!" Ruby said.
Yang's smile only grew. "Really? You're getting turned on from being ordered around by your own big sister~?"
"Y-yes…" Ruby admitted, continuing to finger herself.
"But Ruby," Yang started to purr with sadistic delight. "Don't you have a girlfriend~?"
"I do…but I'd like for Yang to show me the kinds of things I could do with her…"
"That's adorable sis," Yang immediately shot back, a little upset that it wasn't kinkier. Oh well, not every NTR comic could be as realistic as Yang hoped it would be. "Now, you're going to make sure to do everything I say tonight, right~?"
"A-anything…" Ruby said, then momentarily snapped out of it as she corrected herself. "W-well, not ANYTHING, but…a-almost."
Yang chuckled. She'd see about that. Even so, she turned the camera off and set her scroll on the end table. "Good, now come over here and take my shorts off."
Ruby got up and walked over quickly, grabbing Yang's shorts and peeling then down her legs, revealing a black thong underneath that sent another shiver down Ruby's spine. "P-panties, too?"
Yang made a show of thinking about it for a second while she twisted and grinded against the couch, delighting in how every motion seemed to set her little sister off. "Hmm, I'll let you decide~"
Ruby wasted no time in practically tearing off the garment and leaving Yang just as nude as she was. She stared at her sister's wet pussy with hunger, hunger she didn't know she was even capable of.
"Cute~!" Yang praised her sister as she bounced up, her chest heaving wildly as she stuck the landing. "Now…hmm, lay on the carpet."
Ruby gently set herself down, her breasts falling to either side due to gravity as she almost laughed at how the carpet tickled her ass cheeks. She tried to pull the most seductive pose she could as she stared up at Yang and, to top it off, shyly bit her lip.
Yang immediately blushed, taken off guard by how effective Ruby was at getting to her even with her inexperience. She leaned down and grabbed her sister's ankle and hoisted it up before getting on her knees. "Tell me, are you a virgin?"
"Yes."
Yang giggled a bit as she laid back as well before shuffling forward, reaching the point where their pussies were touching. "Perfect~"
Ruby vaguely knew what this position was, and as soon as they touched, she let out a load moan of pure pleasure as her body shuddered uncontrollable. She was even sure she leaked a little.
"This is called scissoring," Yang informed her sister as she began gently rolling her hips. "It feels fucking fantastic, you should've heard how loud Nora screamed when she helped me figure this one out."
While Ruby wanted to press that point further, any words she tried to say were replaced with moans that reverberated through the house as she felt intense feeling unlike anything she'd ever experienced. Seeing what Yang was doing, she began to mirror her, and grind her hips against Yang's, which made it feel even better.
"There…there we go~" the blond girl exhaled. "You're already getting the hang of it, you're a born slut~"
"Please don't…call me that…ahhhh~" Ruby said between moans as she moved her body faster and faster, their wetness helping their pussies to slide against each other.
"Why not~?" Yang teased her as she gripped the carpet. "It takes a really slutty girl to get so wet from doing this with her own sister~"
"I could call you one too then…" Ruby said back.
In response, Yang gave her sister a smug smile. "Of course I am, it's more fun than being a prude~!"
Ruby couldn't help but laugh, which then turned into another moan as she could feel herself getting ready to cum, though she did her best to hold it back as much as possible. "Y-Yang, I…"
"You're already getting close?" Yang asked. "Wow, that's the shortest fuse of any girl I've known."
"Sh-shut up! It…mmm…feels good…"
"Glad you like it~" Yang purred. "Cum for me~"
That was enough for the girl, and she came hard onto Yang's pelvis as she tilted her head back, a loud moan accompanying the burst as she struggled to keep herself up, especially once it was over and she was left panting hard.
Once Ruby finished Yang separated from her and stood up. "Holy shit Ruby, you're a real squirter, aren't you? Penny's a lucky girl~"
"I-I mean…we haven't really…" Ruby said with a blush.
Yang raised an eyebrow. "Oh yeah, I forgot, virgin. Well, in case you hadn't noticed, I haven't gotten to finish yet~'
"Wh-what do you want me to do to…finish you?"
Yang thought about it for a second. Did she really trust her inexperienced sister to eat her out? "Hey, weird question sis, can you open your mouth?"
The girl stared quizzically at her sister as she slowly opened her mouth.
Yang leaned forward and inspected her sister's teeth. Yup, they certainly looked sharp. Shouldn't risk it. "Hmm, how do you feel about learning how to finger a girl?"
"I…w-well…I don't know what sort of…parts Penny has, but maybe that could be useful?"
"Huh," Yang replied with a puzzled tone as she sat down on the couch. "I always assumed Ironwood gave her a dick."
Ruby looked alarmed. "WH-WHY?!"
Yang shrugged. "I assumed that whatever weird nerd made Penny didn't know what a pussy looked like."
"Wh-whatever! Just…guide me." Ruby said as she crawled over to her sister.
"Alright, the important part of fingering is knowing the difference between giving a massage and stuffing a turkey. You've gotta be gentle with it, otherwise it just hurts. Got it?"
Ruby nodded as she stared. "What's the best position to sit or whatever?"
Yang thought about it for a moment. "Hmm, how about you kneel in front of me?" she suggested while spreading her legs.
Since she was already on her knees, she simply moved closer, until her head was nearly between the girl's legs.
Yang couldn't help but blush as she felt her sister stare directly at her exposed, moist pussy. "Okay, so start by gently rubbing the labia with the tips of your fingers. Be careful about your nails, even if they're cut short."
Ruby brought her hand up and did as her sister said, making and effort to use her fingertips and not her nails, and making sure to be gentle about it, looking up at her sister's face to make sure she was doing it right.
Yang winced a bit. God, this was awkward. Oh well, maybe it'd get better. "There we go, now use your other hand and rub the hood of my clit. It's like when you masturbate."
Ruby did her best to follow but it felt much harder doing it from this angle instead of what she was used to.
Biting her cheek, Yang wondered if maybe she should've just taught Ruby how to peg instead. "A bit more sensuality, please?"
"Sorry…" Ruby said as she tried to be even more gentle. "It's…hard."
No, in fact, it's quite wet, Yang thought to herself. "You're doing fine, sis, it's just a thing that requires practices-"
"So…am I doing better?" She asked.
No. "Of course!"
"I can tell by your face I'm not." Ruby said as she stopped and pulled away. "Are you sure this is right, aren't you supposed to do it like…sitting behind the person?"
"I mean, if you wanna try that-" Yang suggested as she climbed off the couch to kneel down in front of Ruby.
Feeling awkward, Ruby moved forward until her breasts were now against Yang's back and looked over her shoulder to move down, and mimicked the movements she used when she masturbated, from a better viewpoint now.
There we go. "Oh…oh fuck~"
Ruby smiled hearing her sister's moan. "There~"
"Yeah, that's much better~" Yang moaned as she shuddered under her sister's touch.
Ruby continued, slowly inserting her finger inside as she stroked the outside with her other fingers, doing her best to mimic what she usually did.
"Wow, already putting a finger in there~? You're a natural~"
Ruby didn't speak and simply continued, slowly humping her body against Yang's to further help her along as she thrusted the finger in and out.
Yang was genuinely impressed by how well this all felt. Her sister's small chest against her back, the surprising skill of her fingers now that she had a more familiar position, the knowledge that she was gonna get back at Weiss so good later - it was all so intoxicating.
To add to it, Ruby slid a second finger inside, hoping Yang was getting close judging by the noises she was making.
"There we go, there we go," her older sister praised her in between moans. "Make your big sis fucking squirt all over the carpet~"
Ruby moved her hands faster and faster, feeling her sister twitch and thrash more and more, seeing her toes curl as she slid in a third and final finger.
Wow, Weiss never had the girl-balls to add a third finger. Was Yang falling in love with her own sister? Possibly. "There we go, there we go-" she sputtered as she felt the heat in her core rise and rise higher and higher.
"Are you…close?" Ruby asked as she was moving as fast as she could manage.
Yang probably would've said 'yes' if she didn't cum almost immediately after Ruby asked, almost screaming as she began to squirt.
Ruby held her fingers inside as she waited for Yang to finish, feeling and watching it explode all over the carpet. Once it was done, Ruby removed her fingers and Yang fell back, panting.
"Holy…shit..." Yang exhaled. "You're so much better than Weiss-"
Ruby blushed. "Th-thank you…" Then there was an awkward silence, as neither knew what to say for a while, now that they had both cum.
"Another round on the game?"
