Work Text:
Yang’s older sister's instincts are tingling. Ruby was in danger, distraught about something. She could feel it and see it.
Normally when she was at the gym, she’d be more focused on exercising, on training to pay attention to such things. And when Ruby was there, even more so. Hell, she’d be doing it to show off to her baby sister, to impress her more than anything. But right now, she couldn’t concentrate with the way Ruby was acting.
The leader of team RWBY was shuffling her feet, squirming, and her hands being held in front of her short-shorts. But what Yang noticed the most was her face, red as her cape and unwilling to meet anyone’s eyes.
After a few minutes of observing Ruby’s behavior, Yang couldn’t take it anymore. Her worry for her little sister was too great to fully concentrate on lifting weight. Putting her dumbbells back on the rack, Yang stretched her sweat-slick body while looking down at Ruby. “Something in your mind, Rubles?”
Almost like she wasn’t expecting to be read so easily, Ruby flinched, her eyes flicking up at Yang before she looked away again. “M-Me? Um, well… Do you promise not to laugh?”
Yang raised an eyebrow. Usually, Ruby would refuse to talk about her issues, and Yang would have bothered her for many minutes, maybe even a whole hour before her little sister would spill her secrets. For her to just skip the process meant that this was a very real issue. The blonde nodded, face serious. She looked around at the gym, at the other Beacon students around them, and gestured towards the locker room. “We should have some privacy there. Let’s take a shower and talk.”
Ruby sighed in relief, at least for a moment before she became nervous once more. With a nod, the two sisters went to the locker room.
/\/\/\/\/\
“So, what seems to be the problem, dear sis?” Yang asked after a moment of silence. She thought she would let Ruby lead the conversation, but after a few minutes of nothing, Yang decided to take charge. Her sport’s bra was already gone, her huge DD-cup breast perky and gravity defying, her nipples a bright pink.
Now put on the spot, Ruby started fidgeting again. Well, not exactly ‘again’ as she never stopped, but it had lessened during the minute. Ruby gulped, wringing her hands together. Taking a deep breath, the young huntress stroked her resolve. “I have some questions… about sex.”
Oh boy, the bird and the bees. Now that Yang knows what kind of conversation they were about to have, she kinda wished they just went back to the dorm. But too little, too late. With a sigh, the blonde gave her little sister her full attention. “Alright then, Ruby. What would you like to know?”
“I, uh…” Ruby was getting nervous again. But with a deep breath, she pushed through. “I have a little, small problem. I, I think it’s better if I showed you.”
“Show me?”
And Ruby did. Being naked with only a towel covering her, all Ruby had to do was drop it to reveal what she was talking about.
Ruby was a futanari, that was something that Yang knew since they were kids, but that was as far as her knowledge of her baby sister went. Hell, Yang was one herself, a proud one at that.
Yes, Yang knew that Ruby was packing something extra, yet she didn’t know just how big she was. Or in this case, how small.
“Oh…” She could tell that Ruby was already hard, the three inch pecker between Ruby’s legs throbbing and dribbling precum already, despite not even being touched.
“Y-Yes. I’m… a little self-conscious about my… um, lack of size. S-So I was wondering if you could, maybe, help me?” Ruby poked her fingers together, misinterpreting the reason Yang grew silent. And sure, the small penis might have been a good reason to stare in shock, but that wasn’t the reason why Yang was staring slack-jawed at her baby sister.
It was because of her huge balls. And when she says huge, she means huge . They were twice as big as baseballs, the balls reaching half way down Ruby’s thighs and brimming with likely gallons of semen! Yang was shocked that she couldn’t see them when Ruby was wearing shorts!
“Um…” Yang shook her head. “Were your balls always this huge?”
“Uh, yes?” Ruby answered. Her face was still red, still nervous and shy. “No matter how many times I j-jack off, they barely get small at all. And when they do, they’d just grow back to this size the next hour! B-But enough of that! I want to have sex one day, but I don’t know if… anyone would want something like… this…”
Yang was starting to understand where Ruby was coming from. Some people didn’t mind the small size. In fact, it was a kink to some other people, but those were few and far between. In all her time, she hardly met someone that was into small penises.
“Well,” Yang wracked her brain for a solution. For something, anything to help her little sister. So in her haste, she spilled the first thing that came to mind. “Who said you had to use it?”
“Huh?”
Huh?
Yang was already beating herself over her head, but she already said it and couldn’t exactly take it back without making herself look like a fool. “I mean… who said you had to be on top during sex? You can… be the receiver instead of the giver…?”
She ended it as a question, cringing a little inside her head at her poor excuse of advice. Ruby stayed quiet, contemplating what her older sister said.
After a few seconds, Ruby locked eyes with Yang. “I… don’t... How do I do that?”
Yang almost sighed in relief. That was one hurdle out of the way. Now comes… the admittedly easier step. Yang plastered on a confident grin and wrapped her right arm around Ruby’s shoulder, unintentionally pressing her sister’s face against her heaving chest. “Don’t you worry, Rubes. I’ll teach you how to suck dick like a pro.”
“Eh?”
/\/\/\/\/\
“Eh?”
Having discarded her own workout clothes, Yang stood as naked as her dear sister. Her dick was over twice as long as Ruby’s. Standing at ten inches long and as thick as a soda can, veins bulging up and down the length, and twitching every second in the blonde’s excitement. Her testicles were as big as orange, befitting the size of one’s own penis, yet compared to Ruby’s, there was no contest.
Yet Yang wasn’t one to pay attention to stuff like that, not when she had a cute, shy little thing sitting right next to her.
They were still in the locker room, sitting at one of the benches right in the middle, and the idea that anyone could walk in on them hasn’t crossed their mind.
Yang leaned back, her now bare DD-cup chest lightly bouncing from that slight movement alone. “If there’s one thing that all bottoms should know, it’s how to suck a mean dick. I might be a little big, but there’s no better trainer than your own sister, amirite?”
“Er, sure?” Ruby sounded unsure, but not put-off. Sitting next to her older sister, the two couldn’t be more different.
While Yang sat with her legs spread wide apart, cock shamelessly on display for anyone to stare at, Ruby had her knees pressed together, her humongous testicles resting on her strong thighs. “Should I get on my knees then?”
“You could…” Yang hummed. “But you don’t have to be. There are many different positions you can be in to give a blowjob. You could be squatting. Or…” putting her right arm around Ruby’s shoulder again, Yang slowly and gently eased her baby sister down until she was laying on her side, face inches away from her fat, throbbing pole. “You can give one while laying down. There’s many options.”
“O-Oh.” Ruby muttered, eyes transfixed on the brimming mass in front of her eyes. It was so close, she could practically feel the heat radiating from it. It throbbed hard, and a bead of pre formed at the tip. Ruby unconsciously licked her lips. “Should I… start?”
“Whenever you’re ready, Rubes.” Yang said. She wasn’t paying that much attention, which she probably should. Instead, it was taken by her sister’s surprisingly plush butt. It looked so perky and soft. Her hands lowered, down Ruby’s shoulder and back, until Yang was grabbing a handful of round booty.
Ruby ‘eep’d at the contact, yet Yang didn’t retract her hand, only squeezing down and watching as flesh bulged between her digit. “Damn, Ruby. I didn’t know you had a nice cake back here.”
“S-Stop being weird!” Ruby cried out, like what she was doing wasn’t any weirder, or the fact that they were doing this out in the open. Her tiny prick pulsed and dribbled watery pre all over her fat nuts.
“Go on. Let’s get started.” Letting go of Ruby’s ass, Yang gave it a loud spank to urge her sister forward.
Ruby gulped, and went back to staring at the intimidating cock. She needed to, no, wanted to learn how to be a good lover. So swallowing her nerves, Ruby grabbed the large prick. She flinched at the sheer heat of the meaty thing, and her fingers rubbed over the veins running up and down the length.
Yang bit her lips at the soft hands gripping her cock, and she lifted her hips slightly. Knowing what they were about to do, the taboo of it all, was getting her more horny than she thought. “There you go Ruby. No need to be shy, this is for you to learn, so go at your own pace.”
“You say that…” Ruby muttered. She knew Yang, how hot-headed she can be. But, if her older sister says she can at her own pace, then she’ll do just that! Opening her mouth wide, she took the first inch of the incredibly large shaft into her warm gullet.
“Oh yeah! Just like that, Ruby” Yang moaned. She twitched inside Ruby, beads of pre spilling from the cockslit, which her baby sister licked up.
It tasted good, sweaty and tangy in a way that made Ruby’s tongue tingle in a pleasant manner. Ruby was hard as diamonds, cock constantly dribbling by now. She didn’t stop there, couldn’t stop. Now grabbing the dick with both hands to keep it steady, Ruby slowly lowered her head, taking another inch, then another one inside her mouth. Her tongue wiggled back and forth underneath the rod, tracing the veins as she went down her older sister’s meat.
Her hands didn’t stay still. With a strong grip, they started pumping up and down, the motion familiar as she had done it many times in the past, yet she was working with more inches, with more thickness, so it was a little bit clumsy.
“Nice and easy, Ruby.” Yang sighed pleasantly, shivering with each flick of her sister’s tongue. “‘Go at your own pace’, remember? Learn what your partner likes, then do just that. Use plenty of tongue, and watch your teeth. The last thing you want is to hurt someone during oral.”
Ruby listened, even while she had her mouth full of twitching dick. She moaned in confirmation, and with four inches of her sister’s cock inside her mouth, the rose slowly bobbed her head back and forth. Starting the blowjob in earnest. Her eyes quickly glazed over, the taste of the shaft, and each time Yang twitched inside her mouth making her spurt another clear pre on her thighs and balls.
“You’re doing great, Ruby.” Yang complimented. Her other hand rested on top of Ruby’s head, fingers gently scratching her scalp. Her right hand continued to squeeze and grope her sister’s soft butt. “Keep going just like that. Do as much as you can, but don’t push yourself too much.”
Ruby heard, but her body was doing otherwise. Each drop of her head, each slurp of her lips, she took another half inch. And before long, she had over half of the prick inside her mouth. The top poked the back of her throat, and the redhead lightly gagged.
“Easy there, girl.” Yang admonished gently. “Throatjobs can come later. It feels good but it’s not mandatory.”
Nodding as best as she could with a shaft in her mouth, Ruby relents for now. Her hands pumping the inches that aren't in her mouth, Ruby bobbed her head up and down, moaning and suckling in the leaking prick with eager want.
Yang groaned above her, keeping her hips as steady as she could but not being able to stop the occasional bucks. The mouth was so warm, the tongue smooth as it licked and teased her raging cock, and the slight gags whenever her tip poked the back of throat were making her shiver with lust. “Good. So good. This feels really good, Ruby.”
Ruby preened at the compliment, slurping and moaning, her soft lips wrapped tight around the girth while throwing her head back until only the tip was inside, her tongue attacking the glands and coaxing more delicious prejizz before she lowered herself back down, gagging at the sheer size of the rod. Drool leaked down her chin and landed on Yang’s lap
Ruby was a quick learner, her mechanical mind paying close attention to her sister’s reactions, and immediately knew what made Yang tick. One of her hands let go of the dick, and lowered down to the orange-sized testicles and gently rolled them in her palm.
“Fuck! Y-You’re really good at this!” Yang gasped into a drawn-out moan. She gripped the back of Ruby’s head, she thrust forward, accidentally ramming her cock down her sister’s throat.
Ruby gagged loudly, unprepared for the rough treatment. Yang’s eyes widened, and she immediately let go of Ruby's head. “Oh crap! S-Sorry, I-I got a little bit too into it and-“
Her words were interrupted by Ruby’s loud moan. Her small dick shuddered, throbbed, then shot surprisingly thick, sticky globs of semen into her thighs and floor. Yang’s eyes widened, watching as her sister came hard without her dick being touched once.
It was incredibly hot.
“Holy shit, Ruby” Yang groaned, the thought of teaching Ruby gone for a moment as she grabbed the back of Ruby’s head with both hands. “Cumming just like that, without being touched…” She pushed Ruby’s head further down, the sputters and gags of her baby sister music to her ears. Her fat, bitch-breaking rod twitching madly as it spilled heaping pre down Ruby’s throat. More and more of her length disappeared into Ruby’s mouth, until her lips touched Yang’s crotch. “…You were meant to be a sub!”
Before Ruby’s orgasm even ended, Yang started to fuck her baby sister’s throat. The tight hole squeezes down tightly on her dick making the blonde groan and gasp with each roll of her hips. Ruby let go of Yang’s testicles in surprise, and the large mass swung up to smack Ruby’s cheek.
“Make sure… to relax your throat. Makes it easier… for someone like me to fuck it!” Yang instructed between each sultry moan. Ruby tried to do just that, but Yang’s throat pounding did not give her the chance to really practice it out. Ruby’s eyes rolled upward, glugs and sputters and gags the only thing she can say.
Yang grunted, lowering Ruby’s head down at the same time she thrusts up, burying thick inches of virile meat into her sister’s mouth. The warm and squeezing throat making her own climax fast approaching. “One more lesson for you: Every bottom always makes sure to swallow every last drop of cum. So I better see you guzzling it all down.”
That was all the warning that Ruby got. Throwing her head back, Yang let out a loud cry as she came explosively down Ruby’s throat. It was just as intense as Ruby’s. Thick semen rolled down the rose’s gullet and settled in her stomach. Ruby moaned and shivered, her hands finding purchase on Yang’s thighs and held on for dear life while she was force fed what felt like gallons of milky cream.
Yang pulled out just enough that the last few spurts of her cum landed inside Ruby’s mouth, the last few more than enough to completely fill it.
“Don’t swallow yet.” Yang demanded with a sharp hiss as she pulled out her still hard rod, the length coated in throat slime and cum. Grabbing the shaft, Yang slowly pumped her hands up and down. “Open your mouth for me.”
Ruby whined pitifully, but with her mind still reeling, thinking only of Yang, she did as told and opened her mouth to show the molten hot spunk inside, her tongue lolling side to side.
“Swallow.”
Closing her mouth, she gulped down the clumpy seed, needing to work her throat a few times before everything finally went down. Without being told to, Ruby opened her mouth again to show that she swallowed it all.
Yang watched on with a lecherous grin. “Now what do you say?”
“T-Thank you, Yang…” Ruby muttered, bringing her face closer and giving the tip of Yang’s cock a kiss.
“Good girl.” Yang sighed in relief. She blinked a few times, and the lustful haze that she fell down on disappeared. Looking down at Ruby, at her disheveled hair, glassy eyes, and messy thighs; her grin turned sheepish. “Oh uh… sorry. I don’t know what came over me. You just looked… really cute and sexy that I couldn’t control myself. I-I’d understand if you wanted to stop.”
Ruby looked up at Yang, almost confused by her words. “I don’t want to stop. If I made you feel good then I’m already doing what I want to do. I want to make my partner feel good in bed, that's why I asked you in the first place.”
Ruby recovered remarkably quick after getting throat-fucked, and Yang couldn’t help but be surprised by it.
“Can we continue?” Ruby asked. “I know there’s more to sex than a blowjob. I’ve seen videos.”
Yang gasped. “My little sis watching porn? I’ll have to confiscate your scroll.” She gave Ruby’s behind another playful smack, grinning when Ruby squealed. “Get your cute little butt up. As much as I love to have you worship my dick a little bit more, we don’t have all the time in the world.”
While Ruby does as told and sits back up, Yang’s eyes went back down to the… biggest part of Ruby’s body. The testicles didn’t look any smaller after the rather long orgasm from Ruby, her left thigh absolutely splattered in white cream.
“I don’t think you’ll be able to do missionary position.” Yang said after a moment. “At least not without us being extra careful.”
“Eeeh?” Ruby whined. “Why not? I want to look into my partner’s eyes while I make love with them!”
“Your balls are huge!” Reaching over, Yang lifted one of the nutsacks, her eyes bulging at how heavy they are. “They’ll get in the way if I try to do it. And I’d rather not hurt you in a moment that’s supposed to feel good.”
Ruby huffed, affronted at the idea that Yang could even hurt her. But she begrudgingly had to agree with Yang’s point. Getting on top of the bench, the little sister got on her hand and knees, shaking her round, soft butt in the blonde’s direction. Right between her legs, previously hidden by her cum factories, was her slick, drenched slit. Outer lips puffy and innocent-like. “Then this position is fine, right? Stick it right in and show me how to be a bottom.”
“Getting a bit eager there, aren’t you?” Yang’s grin was back, shuffling up to inch her way closer to her sister. Her fat rod slapped down on Ruby’s left asscheeks, and the brawler grabbed a handful of the other one, fingers digging into the flesh while listening to the rose’s sweet gasps. “I thought we were supposed to learn here.”
“Was that before or after you grabbed my face and used my mouth?” Ruby shot back, pushing her plush rear back and grinding against Yang’s slick, throbbing pole.
“Got a mouth on ya, huh?” Yang groaned. Pulling her hips back, she pressed her tip against the entrance to Ruby’s pussy. The heat radiating from it made her shiver. “That’s fine. Fucking you to submission is just what the doctor ordered.”
Yang tensed up, prepared to sink every last inch of her dick inside her own sister when she hesitated. “Is this, uh, your first time?”
“Uh, yeah?” Ruby said in confusion. Looking back, she raised an eyebrow. “Is that a problem?”
“Well, I mean…” Yang scratched the back of her head. “You aren’t… saving yourself for anyone, are you?”
“No one in particular.” Ruby shrugged. “And if it’s you that takes my first time, all the better. There’s no one I'd rather have.”
Yang smiled genuinely, her love for her baby sis soaring at this very moment. “I’ll make sure you have the best fuck of your life. I’ll treat you just how you should always be treated.”
Her fat prick prod Ruby’s slick folds once more, only this time, Yang didn’t let up the pressure, and her tip quickly spread the flush lips. Ruby bit her lower lips, a guttural moan leaking out with just the tip inside of her! It was already more than she could handle, but she didn’t tell Yang to stop. She needed to take more. To be a good sub!
“ Brothers , you're tight!” Yang hissed. Both hands smacked down on Ruby’s bubbly ass, then grabbing a handful, making the younger woman squeal, then moan at the sting. “Good. People love it when their toy’s tight as fuck.”
“T-Toy?!” In an act of defiance, Ruby pushed her hips back, taking more inches of prime meat inside her quim. And while she shiver and drooled sticky precum on the bench, Yang yelping was the reaction she wanted most. “I-I resent that! I’m nobody’s toy!”
Gritting her teeth, Yang glared down at her little sister, who was glaring back over her shoulder. The blonde grinned a few seconds afterwards, and puts her hands on Ruby’s shoulder. “You’re so right. But be sure to tell me that after you can handle this !”
Yang slammed the rest of her length forward, her hips loudly slapping Ruby’s butt and her tip knocking against her leader’s cervix.
Ruby had no way to prepare herself for it, and her eyes rolled upward with a shocked cry of pleasure. In true premature fashion, Ruby’s dick twitched madly underneath her, spilling a fat load of virile jizz all over the bench.
Yang wasn’t unaffected by this, moaning loudly from the feeling of her sister’s incredibly tight cunt gripping down on her hung shaft. Clenching down with each creamy cum that Ruby let out. “You might have a small dick, but you cum like a fucking horse!”
“S-Shut up…” Ruby’s words were slurred, tongue-tied from the mind numbing pleasure. Yang groaned from above, rolling her hips backward and pulling out her fat pillar of meat out of the clenching folds. Once only the tip was inside, she rammed herself back inside, her balls smacking against Ruby’s much bigger pair.
Pulling back again, Yang rammed every last inch of her bitch-breaking cock inside her sister. Again and again. In and out. The blonde setting a fast, punishing pace as she fucked her own sister into the bench.
“Oh! Ahn! Mmm!” Ruby cried and moaned, her dick swinging wildly back and forth underneath her, her orgasm over but another quickly approaching the inexperienced girl.
“I was planning on being gentle with you.” Yang huffed and grunted, her hips smacking loudly with Ruby’s round butt and watching it jiggle. Each thrust from her made the pussy spasm and cling tighter to her shaft, the wall squishy and soft and molding to the shape of her dick. “But someone has to fuck that attitude out of you. And as your older sister, I’ll do just that!”
Yang put pressure on Ruby’s shoulder, slowly pushing her down with every buck of her hips until the redhead was laying face-down, ass-up. Meaty slaps sounded out in the locker room with each impact of Yang’s hips against the rose’s butt.
Each thrust filled up Ruby’s pussy to the brim with cock. Ruby howled and groaned, gripping the bench as she felt every veiny inch of her sister spreading her apart!
Yang held her down, keeping her little sister in her place as she fucked her. Every roll of her hips, every slam sends her mighty prick inside the velvety soft slit. And all Ruby could do is take it, bent over, cute little butt held up and repeatedly slapped by Yang’s waist. And it was a very cute butt, the flesh jiggling and bouncing up and down in such an enticing manner that Yang wanted nothing more than to slap it! Though she held herself back, for now.
Ruby could feel every vascular inch of prime meat sinking into her clenching pussy, stretching her wide open and hitting spots that made stars flash in her eyes. She could feel something big and hard hitting her testicles, barely half the size of her sack but still very heavy. The redhead flinched, her dick swinging back and forth and flinging clear pre everywhere on the bench.
“That’s it.” Yang licked her lips. Her hips came crashing down, her cock stirring up the tight, drenched slit of her sister’s. Her shaft throbbed hard, sticky pre leaking through. Ruby felt amazing! Tight. Slippery. Soft. Squishy. Wet. Yang was quickly finding herself getting addicted. “You’re gonna be a good girl and take my big dick, aren’t you?”
“N-Nooooo~” Ruby gasped and mewled, her noise just as loudly as Yang’s grunts and moaning. “It doesn’t feel good at all! I-It doesn’t-“
As if her own body was arguing with her, Ruby was fucked to another orgasm, her dick swinging and letting out a heaping amount of of sperm on the bench. So much that some were already leaking down the side and into the floor. Her pussy spasmed, clenching down tightly and gushing clear fluid all over Yang’s waist.
Yang growled, lifting a hand up and slapping Ruby’s right asscheeks, making the younger girl squeal. “What was that you just said? ‘Didn’t feel good’, huh?! It’s bad to lie, Ruby. And just for that…” She grabbed a hold of Ruby’s waist, her hips jerked forward, hammering her thick, throbbing pole of girldick inside the spasming slit. “You’re gonna take every. Last. Drop!”
One last thrust from Yang, pressing her hips as close to Ruby’s wiggling butt as she could, her dick firmly inside and tip pressing against the cervix of her dear younger sister, and came .
Ruby’s eyes crossed, and her moans of pleasure resounded across the locker room. She felt the first, fat spurt of creamy cum shot from Yang’s dick and fill her womb. Then the second one, then the third. Just as plentiful, just as thick, just as hot as the last!
Just as one would expect, Yang came a lot. Not as much as Ruby, surprisingly. Probably the only thing that Ruby had over her sister. And the size of her testicles. More and more semen flooded the rose’s quim, the thickening length rubbing against her inner folds and making her shudder with each throb, with each pump.
Yang leaned down, pressing her bountiful chest against Ruby’s back and trapping her underneath her muscular form. “How is it? Being pinned down and fucked like like this?” She rolled her hips forward, one of her hands reaching underneath to grab Ruby’s still cumming dick.
“Yang…” Ruby whined, body shaking from the thrones of pleasure when she felt strong fingers wrap around her shaft, tugging and urging more of her thick semen to spill out.
With a rough tug of her hips, Yang pulled her hard cock out of her sister’s well-fucked slit. Clumpy seed spilling out of the gaping hole immediately, sliding down Ruby’s far nuts and into the bench, joining the mess that she already did.
Ruby already felt tired. Three orgasms was a lot more than she ever came in such a short period of time. And her mind was still reeling from the intense fucking that she was subjected to, her pussy feeling hot and so very full to the brim with Yang’s virile jizz. It was a surprise that Ruby’s knees didn’t give up on her yet.
“Alright, ready to go another round?” Yang’s voice roused Ruby from her afterglow. Ruby blinked, looking over her shoulder towards Yang and her still very much hard dick jutting forward.
“H-Huh?”
“Don’t you ‘huh’ me.” Yang rolled her eyes, shuffling forward to grab both of Ruby’s delicious cheeks. “As the bottom, you don’t get to relax until the top is done with you. So get your cute butt up and get ready. I want to keep going.”
“I-Is that really a rule or something?” Ruby whimpered, already struggling to lift herself up, yet her arms felt like jelly.
“It is for me.” Yang grinned victoriously, dick throbbing and urging the young rose to move faster. “We'll have to teach you many different kinds of positions to get you familiar with how to take a nice pounding.”
Ruby gulped, her body shivering in both fear and hidden delight. Her dick, which was getting softer, sprung up to full hardness in less than a second. “Can I at least get a break?”
“No~”
/\/\/\/\/\
The next sex position was, of course, cowgirl.
“You can’t just lay down and let your partner do all the work.” Were Yang’s words. And if nothing else, Ruby hated to disappoint anyone. It was the main reason why she asked Yang for help in the first place.
Gritting her teeth, squealing and mewling with pleasure, Ruby dropped her hips down, impaling herself on that fat cock. Yang was sitting leisurely on the bench, away from the cum stain. Her legs were spread wide open, giving Ruby all the room that she would need to ride the long and hard prick.
With both hands and feet firmly on the floor, Ruby gritted her teeth while lifting up her hips before slamming them back down, letting out a struggling cry of pleasure.
This feels so much different than when Yang was in charge. Ruby was made aware of every vein-riddled inch as it slid inside her hot depth, pushing aside gripping walls to hammer all the way to her cervix. Her toes curled, and her small cock throbbed hard with a steady stream of pre drooling out of her cumslit and into the growing puddle underneath her.
“That’s a very nice ass you have there. Did I ever tell you that?” Yang said, rather casually too as if it wasn’t her own sister that was riding her large dick.
“M-Multiple times…”
“Good.” Smacking a hand down on Ruby’s left cheek, the blonde watched eagerly as the butt bounced up and down, the flesh jiggling and rippling each time it impacted her waist. “You’re doing very well. Keep doing, just like that.”
Ruby does as she’s told, whimpering submissively while throwing her rear down, sinking every last inch of her sister’s meat inside her folds. Every corner of her cunt quivering, spasming, gripping down tight on the hot cock.
Ruby was turning delirious, mind spinning and breath heavy as she fucked herself on the dick that was filling her to the brim. Hitting her g-spot and making her knees go weak and shaky. She was very close to cumming already after barely a minute of bouncing her perky ass on her sister’s lap.
Correction, she was cumming now .
“Ohh fuuuu-“ Ruby gritted her teeth, practically foaming at the mouth as she came just as hard as before, blasting a chunky load of semen into the floor.
Yang was not unaffected by this, hissing and groaning when Ruby’s cunt repeatedly clenched down in time with each burst of cum. She could hear the ‘spurts’ and splatters of semen making a mess on the floor. “Y-You horny beast. You’ve been pent-up, haven’t you? Is that why your balls are so huge?”
“N-Noooo~” Ruby slurred her voice once more, the orgasm mind-numbing, only able to feel the bliss of releasing another batch of virile jizz while her sister’s fat prick throbbed inside her. She rested her wide hips on the blonde’s waist, shivering and shaking.
Something that Yang didn’t like.
“Hey!” Giving another hard smack to Ruby’s reddening ass, Yang growled down at her baby sister. “Who said you could stop? You think just because you came that it’s ok to take a small break?”
Ruby whimpered, wiggling her hips left and right and stirring up the pulsating meat inside her muff. That just earned her another smack on her plush ass.
“Move those sexy hips, and don’t stop until I cum again.” Yang demanded. And Ruby, being the sub that she was, does as told. Dick still spilling her white seed on the floor, the redhead moaned and groaned, swinging her hips up and down, her pussy making wet squelching sounds as it swallowed up over 10 inches of white meat into her sodden box.
“Another rule,” Yang grabbed a hold of Ruby’s waist, urging her on to go faster, lewdly smacking her butt down her lap. “Even when you’re cumming, never stop moving until your dom tells you to stop.”
“B-But…” Ruby gritted her teeth, her hips sore but still moving as best as she could. Huffing and grunting and moaning, her pussy spasming and growing tighter whenever she felt the stiff prick hammering inside her bumpy inner folds.
At some point, Yang started to add her own thrust, the pleasure too much for her to hold still. Every buck of her hips sank vascular inches of her meat into her sister’s tight, puffy pussy. The round ass jiggled, both cheeks red and so very soft to the touch.
Every time Yang’s tip hit her cervix, Ruby’s cries of pleasure grew louder. She could feel another orgasm already approaching, her testicles rumbling and growing tense with each passing second. Ruby would have felt embarrassed by what a quick-shot she was if it didn’t feel so good !
“H-Here it come, Ruby!” Yang grunted, leaning forward and grabbing a hold of Ruby’s hips with a vice-like grip. Ruby didn’t have to wait long. With a final drop of her wide hips, Yang’s cockhead breached Ruby’s cervix, straight into the already filled womb and unleashed her second batch of baby batter.
“Ahhh!” Ruby cried out in pleasure, her eyes rolling as she felt the hot, sticky seed splattering deep inside her slit, her womb hungrily swallowing down the fresh load of virile spunk. Her small dick twitched and throbbed, cumming again and spilling copious amounts of semen on the floor.
Yang growled, gritting her teeth while swirling her hips back and forth, stirring her meaty prick around the squishy insides of her sister, the noise wet and lewd and making her pulse with more seed to dump inside her sis. She could feel Ruby’s giant pair of testicles clenching and lifting against her own above average nuts.
Reaching her hands around, Yang lifted Ruby until she was properly sitting on her lap, soft breast squished against Ruby’s back. Her orgasm was long, but eventually it petered out. Enjoying her afterglow, the busty blonde hugged her baby sister close, her hands slowly teasing Ruby’s modest tits and hard nipples. “You were wonderful. I’m sure you’ll make many girls happy. I know I am~”
Ruby leaned heavily into Yang, shivering and groaning. She could barely feel her legs, the pleasure still coursing through her body and making her mind feel so numb. Yet she never felt better.
‘ Is this what sex feels like ?’ Ruby asked herself. A steady stream of white jizz drooling from her small cock, and her balls were still insanely big even after cumming five times already. Ruby could feel Yang’s smaller pair of testicles pressing against hers from behind, and just knowing that the semen inside was injected inside her womb made her feel warm inside. Or maybe that was the cum still inside her.
Ruby felt a tap on her right thigh, and turned her head to see Yang grinning once more. “Ready for more?”
“H-Huh?” Ruby was stumped, could someone seriously have this much energy? “Don’t you at least need a break?”
“Nope! You still have to learn all kinds of positions, and I want to get all of them out of the way now instead of later. You’ll learn everything from me.” Yang purred, her right hand once more reaching up to cup her sister’s chest, enjoying the mewl that she got out of it. “And we don’t have that much time here. Someone could walk on us at any moment. We were lucky that it hadn't happened yet.”
“B-But-“
“It’ll be good for you.” Yang interrupted. “You’ll learn the ins and outs and become a bonafide slut for girldicks.” Though at this point, Yang was less looking to teach Ruby and more wanting to have sex. This was just killing two birds with one stone.
Lifting her squealing little sibling over her shoulder, Yang marched towards the shower to finally have a bit of privacy while getting ready to rock Ruby’s world. ‘ Best idea ever! ’
/\/\/\/\/\
A couple of hours and many, many sex positions later and Yang was ready to call it a day.
“Whew.” Yang wiped her forehead, unnecessary with the cascade of water running down her sore and sweat-slick body. “Who would have thought that the best lay of my life would be my own sister. Well, learn something new everyday, right Ruby?”
Ruby was in no position to respond. Laying on her back, she was covered from head to toe in a layer of spunk, the shower head doing its best to wash it all off. Her pussy was gaping, fat clumps of seed still drooling from her over-stuffed cunt, making her once slim tummy swell up to the point that she looked pregnant. Her dick had gone flaccid a while ago, unable to keep up with Yang’s sexual prowess. It didn’t stop her from cumming buckets however. Her mouth hung open, tongue sticking out and eyes rolled upward in a lewd ahegao.
Yang stood over her fucked-silly leader, like a hero triumphant over a villain. “I’ve cum a least a dozen times.” Yang continued despite getting no answer from her sister. “You probably came twice as much. Man, I’m kind of jealous of you.”
Ruby groaned, finally making some kind of noise.
“And hey, if you ever need anymore ‘help’, you know where to find me.” Yang winked down at her sister. When she didn’t get a response this time, she sighed. “Though we’ll need to work on your stamina later. You were doing so well too.”
Ruby twitched.
“Well, I should probably get you cleaned up and out of here. Weiss and Blake are probably worried sick at this point.” Yang bends over to pick up Ruby, her hands grabbing and squeezing down on her waist. The flesh yielded to the strength in her grip and Ruby moaned when Yang accidentally put pressure on her cum-bloated belly.
Yang felt a stirring between her legs.
“Buuuut I’m sure they wouldn’t mind us being gone for a little while longer, right? You wouldn’t mind one more round, right Rubes?”
Ruby moaned again.
“Didn’t think so~”
/\/\/\/\/\
Ruby’s life has changed for the better after the event in the locker room. She grew more confident in herself, more outgoing and flirted with any cute student that she finds, even scoring with some of them in the bedroom if she really tried.
Of course she was always bottom, the one that gets fucked instead of doing the fucking, but that was fine by Ruby. She was shown that there was more pleasure than simply sticking her dick in something.
Whether it was someone as hung like a horse like Coco, or as small and dainty as her like Velvet. Though she would always make sure that they wore a condom at the beginning, there would be many nights where she’d run out and have to resort to doing it raw. Something that she secretly likes.
Yet there was one change that Ruby loved most of all. A big one. One in her very dorm room.
“Do you seriously have to do that now?” Weiss wrinkled her nose at the pair of sisters.
Yang has an aura of smugness while staring down the heiress. “What’s wrong Ice Queen, jealous that you can’t have a cock-sucker to relieve you anytime you ask?”
The blonde brawler sat down on Blake’s bed, naked from the waist down with legs spread open. Between them was a kneeling, naked Ruby Rose. Her round butt was jutting towards her petite partner, and her small penis was constantly leaking pre on the floor. Her head obediently bobbing up and down Yang’s huge shaft, slurping and gagging and moaning all over the hot, meaty length.
All the slutty, kinky noises that she made sounded outright depraved to Weiss’ high-class ears. And all Yang did was grin, cock twitching in the confines of Ruby’s tight throat.
“You knooow, I could lend her to you if you ask nicely.” Yang mused. A shudder ran down her body, and she pressed a hand on top of Ruby's head, pushing her lower, much to the rose’s enjoyment.
Weiss looked affronted at the mere suggestion. “How dare you? You think you can just throw your own sister to anyone just because-“
“I’d like to try her.” Blake said, stepping out of the bathroom with a towel wrapped around her head and nothing else. Her Faunus dick was already hard, twitching at the sight of Ruby. “It’s not everyday that you get an eager slut for you to use as your toy.”
“See, Blake gets it!” Yang said. Ruby, hearing everything, raised her soft butt high in the air and shook it back and forth, her large balls hanging low between her thighs.
Weiss bit her lips, using her hands to push down her pitching tent in her combat skirt. She very quickly changed her tune. “F-Fine. I guess… one day wouldn’t hurt…”
Ruby shivered in excitement, feeling like she could cum at any second as Weiss and Blake stalked towards her position.
This was shaping up to be the best day ever!

Ruby and Yang weren’t as inconspicuous as they thought they were while having sex.
Students walked in on them.
A lot.
Pyrrha happened to be one of them.
It was only for a brief moment. After finishing her work-out, Pyrrha was looking forward to a nice, relaxing shower in the locker room. Only to walk in on Yang getting a blowjob from Ruby.
She squeaked and hid behind one of the lockers, face turning red with mortification. ‘ Are they seriously… ’
She peeked again. Nothing changed. She could hear the wet slurps and Yang’s encouragement, which honestly only made Pyrrha feel more embarrassed by the second.
More students walked in, only to quickly step out with beet-red faces. Pyrrha didn’t blame them.
She didn’t know what to do. She needed to freshen up before she left for her dorm, but she also didn’t want to get found out by Yang and Ruby. W-Why were they even having sex here in the first place?! Pyrrha had many questions!
“Hello Pyrrha!” Nora walked into the locker room, being as loud as always. Only to quickly be shushed by the redhead.
“B-Be quiet! W-What if they hear you!?”
“Who?” Nora blinked, looked around the corner, then gape in shock at the incestious sisters. “Oh wow.”
“No, not ‘oh wow’! Do you have any idea how many people saw them? Brothers, how many saw before I saw them? We have to stop them! T-Tell them to do this in privacy o-or something or- what are you doing?”
“Huh?” Nora blinked again, her scroll aimed at the two sisters. “I’m recording, duh.”
“W-W-W-W-Why!?” Thinking back on it, Pyrrha was surprised that she wasn’t heard by the pair in the locker room. “You… You aren’t planning on blac-“
“Yep, I’m putting it on a porn site.”
Ok, not as bad as Pyrrha thought it was gonna be, but still bad. “Again, why?”
“Why not?” Nora shrugged. Hands surprisingly steady while recording the doggy style fucking happening to Ruby. “People would pay to watch stuff like this. Wouldn’t be the first time I did this.”
“Wha- That was you? You’re the one that keeps recording our friends having sex?!” Pyrrha accused.
“Well yeah. The account name is Valkyrie_Aron.”
Pyrrha opened then closed her mouth.
Another student walked in, then walked back out.
All the while; Yang and Ruby were none the wiser.

Neo sighed in relief. Or at least, made a noise as close to that as she could. All these missions that she’s been doing the last few days were running her ragged. She needed a way to unwind, to finally relax after a full day of doing nothing but espionage and murdering.
And what better way than to fuck a stupid girl stupid?
Someone like Ruby Rose.
Ruby didn’t know how she got to this place, or who this multi-colored hair woman was. All she knew (and felt) was the dick currently rearranging her tight cunt. And the warm essence filling every corner of her hole.
“Neo, is your scroll broken? I’ve been calling you for the past 30 minutes!” Roman rudely threw the door open, bearing witness to Neo’s and Ruby’s compromising position.
Head down, ass up, the redhead silver-eyed warrior didn’t even know that Roman was there, groaning and shivering from the thrones of pleasure. Neo was right behind her, dick sunk deep inside her.
Roman took one look at this, wrinkled his nose, then addressed the situation. “Huntsman are outside our doorsteps right this second. We need to leave now !”
Neo pouted, gesturing to Ruby. Only for Roman to shake his head. “Hell no. We are not taking her with us. Believe it or not, Beacon actually cares for their students. If they find her missing for an extended period of time, they’ll be at us like ants to honey! We can’t afford to keep her!”
Neo does the puppy dog eyes.
“Nice try. That won’t work on me. I’m a hardened criminal. Now dress up little red and at least make her presentable before they find us.”
Neo does the puppy dog eyes harder.
“Neo…”
Neo’s bottom lip trembled.
“...Ugh, fine. Only for one or two days, then we'll bring her back!” If Neo could cheer, she would have.
Gathering up what belongings they had in this hideout, Neo and Roman escape the police yet again, only this time with extra baggage.
‘ Where am I going? ’ Ruby asked herself. ‘ Yang will come get me back, right? ’
She ended up spending a whole week being Neo’s plaything.
