A pair in the bed is worth four in the room
Weiss and Blake had already left for the afternoon, each to their own individual pursuits. Blake was headed for the library, Weiss to the cafeteria in search of she called "a half-decent afternoon tea and scones".
That left Yang, who was actually relaxing with her scroll while Ruby was in the team bathroom showering. Ruby's showers were never quiet. The girl usually rambled, going on about her day, her misadventures, or just sometimes breaking out into song.
Today though, all was quiet.
Yang was confused when Ruby, already a shade of red, poked her head out of the bathroom door. The water was still running in the background as Yang looked up from her scroll at her nervous sister.
"Yaaang…" she almost whined, but with a pleading needy tone that sounded more the girl had an accident.
Yang stood up, walking over to the bathroom door. "Ruby, is everything okay?" She asked, trying to peer around the door, but Ruby had tucked herself behind the door to keep her sister from seeing her body.
Ruby shook her head no. "Um, well…it's…swollen…and red…and…" the younger sister looked she was about to cry.
Yang softly sighed. "You haven't gotten off lately, have you?"
Ruby whimpered. "Well, no! It's just…I've been busy being leader of my own team!" She retorted, turning off the shower as Yang could hear her sister's footsteps on the wet floor.
Ruby opened the door, revealing her dark red, puffy, swollen, pre cum leaking dog cock, complete with large knot at the bottom.
To Yang, it looked bigger than before, but maybe this was due to Ruby still growing recently. Yang had seen her sister's cock before, having jerked, tit jobbed, and even had sex with Ruby when it wasn't enough for the younger sibling. Normally, a few pushes with her Xiao Long pussy, and Ruby's knot and half of her cock would pop right out of her.
But this…this looked a bit big, even by Yang's secret size queen standards.
Yang loved big dicks, almost as much as she loved huge amounts of cum. She'd been keeping a log of how much cum Ruby made and how big her knotty cock got.
Ruby noticed Yang's nervous staring, blushing. "Are you okay Yang?" She asked, wondering if her sister was alright.
Yang tried to respond in the mixture of both pleasure and fear in her brain. The more excited she got, the more scared she was Ruby would get stuck which in turn fueled her newly found exhibition streak, actually wanting to get caught.
Ruby was more surprised as Yang didn't respond, slipping out of her clothes before lying on her bed on the side, her legs together with her soaking pussy dribbling fluids down her thigh.
Yang crooked a finger at Ruby. "Why don't you come over and find out?"
Ruby had never been harder before, swearing she would lock up, swell and cum from just touching Yang's pussy.

Now that yang is back with her sister and knows she is safe. She has to make up for lost time by plowing her and making sure she doesn't run off with the new boy R
No one dared interrupt the undoubtedly vicious pounding Yang was dishing out in the bedroom. All they heard were loud thuds and Ruby's screams. Those two things painted a pretty good picture of what was going on.
Yang was on top of Ruby, the blonde brawler currently driving her massive cock up Ruby's ass, splitting the orifice apart as it desperately tried to make room for the large insertion. Ruby clawed at the bed sheets, her mind turning to mush as Yang shoved inch after inch deeper inside her. She didn't know how much more she could take.
And her sister didn't seem to care. All she wanted was to break Ruby, break the sister who left her when she needed her most. And that was just what she was going to do.

Yang never lets any one get a ride with her on Bumblebee unless they ride he massive cock first not even her sister
As Yang presented her massive cock to Ruby, the younger Huntress couldn't help but gulp in fear. "Y-Yang, any chance I can get off easy? S-Since we're sisters?" Ruby asked.
Yang smirked. "Of course not Ruby, if anything, since we're sisters, you should get it twice as hard."
Before Ruby could speed away, she was grabbed by Yang and dragged to the bedroom, where she would surely be destroyed by her older sisters cock, just like the other members of team RWBY.

"Yang, wait, can't we talk about this?" Ruby exclaimed as her skirt and panties were stripped off of her by Yang, causing a crowd to form around the pair."Everyone can see!"
Yang grinned as she tied Ruby's hands behind her back before bending her little sister over."That's the point, little sister!" Yang dropped her pants, revealing her massive shaft, letting it plop down on Ruby's small butt."You ready to pay?"
Ruby desperately shook her head, but it didn't mean anything to Yang. The blonde thrusted her hips forward, burrowing her massive shaft deep into Ruby's tight little love tunnel. Ruby screeched as her asshole was spread open by Yang's size, her older sister tearing her ass apart. The meaty log-like cock thrusted deep within her, shifting her organs around as it was burrowed deeper and deeper inside of her.
Yang then ripped her cock out of Ruby's gaping asshole before plunging in again, this time hilting herself in her little sister, her balls slapping against Ruby's dripping cunt. Students watching the scene began recording as Ruby was fucked into a brainless slut.
As Yang finally came into Ruby's ass, flooding the now wide hole with gallons of her love batter. Maybe this would make Ruby think twice about using Bumblebee without Yang's permission. Or maybe Ruby would do it again, just to get this treatment again.

"Ah!" Yang clapped her hand to her mouth after she awoke with a gasp, struck by sudden sensation. That sound was the first disruption of the dorm's morning peace, and the strained look that appeared on Yang's face indicated that there was more to come. She tried to keep quiet, but the feeling that woke her up just wouldn't go away.
Focusing for long enough to tilt her head down, she saw a tell-tale bump in her blankets, confirming the thoughts that her still-awakening mind was putting together. She bit back a groan as she pressed her head back into the pillow underneath, trying to keep some sort of control over herself. "Ruby, please!"
As a response to that simple request that meant so much more than Yang could put into words, the presence under her covers let out a giggle. A giggle that worked to place more sensation directly onto the sensitive flesh of Yang's sodden pussy.
It took just a moment for the tongue that woke Yang up to return to its place, circling her stiff lower nub as two delicate fingers gently pistoned in and out of her slit. Judging by how unbelievable everything already felt, Yang could only assume her sister started playing with her long before she woke up, and the approaching orgasm just confirmed that even more.
Grabbing her pillow, Yang clasped it over her face as she screamed into the fabric, reaching her peak and losing control over her voice. Her legs spasmed as her body tensed and arched, all while her tight sex clenched onto Ruby's fingers with all its might.
"Yeah, right!" Without needing to wait, Yang plunged her fingers inside, bringing a delightful gasp from her little sister's lips. "As if you're ever anything but!"

Hunger Pangs
"Sis! I'm hungry. Don't we have anything to eat?" Ruby whined, clutching her stomach like she was about to starve to death.
Yang put her hands on her hips, amused at her sister's theatrics, before an idea almost visibly struck her. She pulled her sister to her and down, driving Ruby to her knees. Ruby ended up with her face pressed against Yang's bulge, still hidden in her black shorts, but already half-hard.
"Sure thing, Rubes! I've got a sausage for you right here."
Ew! Yang!" Ruby squealed, half-heartedly trying to get away. "Don't be nasty."
"Oh? That's not what you were saying last night." Yang started humping her hips forward, driving her dick against Ruby's face.
What? No, no I didn't," Ruby said, lying badly.
Yang scoffed and rolled her eyes. Tugging at her crotch, she got her dick out, and let the rapidly hardening member slap across Ruby's face. Ruby moaned, and her hands twitched at her side.
"Come on, Ruby, open up. I've got a nice, tasty treat for you. Just work your way down to the cream filling," Yang said with a wink.
"Ya-" Yang cut Ruby off when her sister made the mistake of opening her mouth.
The blonde sighed in satisfaction as her cock was enveloped by Ruby's warm mouth. Ruby stared up at her sister, a mixture of poutiness, lust and betrayal in her eyes. Yang smiled down at her, working her fingers through Ruby's scalp. Getting a good grasp with her short black hair, Yang used her grip to start facefucking her adorable little sister, just the way the two of them liked it.
Ruby squirmed underneath Yang, her hands quickly disappearing underneath her own clothing, seeking out her breasts and crotch. She started jilling herself as her beloved older sister used her mouth as a masturbation aid, slamming her up and down her cock.
"Oh God. Ru- Ruby, you ready for your treat?" Yang's voice was tight as Ruby's mouth worked it's magic.
"Mmmhhmmh!" Ruby pinched a nipple as she hummed loudly around the cock filling her mouth and throat.
Yang pulled Ruby's head as far forward as she could, burying her dick down Ruby's throat. She moaned deeply as she came, shooting a thick tide of cum into her little sister. It felt like she came for five straight minutes, unloading herself into her sister as Ruby thrashed underneath her in her own orgasm.
Finally Yang pulled out of Ruby, letting the smaller girl catch her breath. While she recovered, Yang amused herself by rubbing her messy, cum-covered dick against Ruby's face, smearing it with leftover cum.
"Yang! I wanted a snack. I didn't get to taste that at all," Ruby complained.
"Oh yeah? Well, here's the solution to your problem!" Yang slapped her cock against Ruby's cheek.
As Ruby started licking Yang's cock clean, the older girl put her hands behind her head and smiled. There were advantages to living with an always hungry younger sister.
