Sisterly Love

Ruby skipped to the beat as she listened to music using her signature black and red headphones. She had been playing Casey Lee William's new album the whole trip. It was strange how Yang sent her off to get groceries alone, but she was making the most of it.

The song ended and she took a second and stopped walking, taking out her scroll and shifting the grocery bag she was holding. She flipped through to find a new one to bop to.

'Did she really need all this stuff that badly? We have dinner planned already. She didn't even come with me. Some sister she is...well I guess I could have asked someone else to help.' Ruby mulled to herself, searching through her music. After finally selecting a song, a quick ad popped up for the Schnee dust company. The logo in itself immediately reminded Ruby of Weiss.

'It would be nice if Weiss came along...Oh well, next time.'

The music started, and she continued.

"Well, at least I got an extra box to eat on my way home, ehehe.~" Ruby said with a cute little laugh, sneakily grabbing a cookie from her grocery bag and gleefully snagging a bite.

She had no idea what atrocities were occurring where the rest of her team was.

"I-I came. I came again, Mistress." Yang cried out, panting as she lay on the bed. The poor huntress sounded absolutely exhausted. She convulsed in aftershocks from the rough treatment.

Next to her, Blake lay spent with stains of her orgasmic fluids still glistening on the bed sheets. Unconscious from the treatment Weiss had so mercilessly given her.

There was a loud unexpected slap on her ass, forcing her to cry out again.

"You slutty bimbo. You weren't allowed to cum yet." Weiss said, with a cold tone. She stared at Yang's pink swollen ass.

"I'm sorry. I'm sorry Mistress. I'm trying to be good. I'm trying."

"Trying!? Then why did you cum?!"

"I'm sorry. I'm sorry. It's because...It's because..."

Weiss smirked. Yang sounded so pathetically apologetic, the question wasn't ever needed. Weiss knew exactly why. This entire time Weiss had been sitting naked beside the panting blonde. But it wasn't only that, she had been holding something with a large girth inside Yang.

"Go on, tell me why you came."

"Because of my arm. It was my prosthetic arm...it's inside me...and...I came. You fisted with me and I came! Oh God it's inside me still!"

"Yes, yes it is." Weiss said, pushing it in again. Yang's overly stretched pussy taking it in.

Weiss pressed a hidden button on the side of the arm, and the entire arm started vibrating.

"Ahhh! Mistress please! I can't. I can't again! I-I- Ahnn! I'm SORRY!"

"Since you love cumming so much, why would we stop here? Blake took it like a good girl. You will too. Right?"

"Hnn...Y-Y-Yes..."

Yang's sheepish little answer didn't seem to suffice for Ms. Schnee. She pushed Yang's prosthetic arm deeper into her sopping wet pussy, enjoying the helpless shivers of her pet.

"Mistress? M-MISTRESS!? ...HNNN!~...YES! I SAID Y-"

"Yes?" Ruby said, pausing her music to pick up the phone."

"When will you be back?" Weiss said casually over the phone, licking her fingers clean.

"Oh I was on my way back already. Should be about 10 minutes."

"Hnn...sorry...mistress...break..." The delirious blond mumbled, drooling onto the sheets as her tired body lay face down on the bed. Her robotic arm glistened in her juices, the hand curled into a fist right outside the folds of her vagina. Her cunt still shivered in post orgasmic bliss, the holes till gaping slightly from Weiss's merciless ravaging.

"Is someone else saying something there?"

"No, I'm alone in my room." Weiss said, pressing her foot on Yang's head, pushing her face into the mattress to muffle her words. The soft silk white cloth covering her feet pressed firmly against Yang's, pinning her down.

Ruby frowned, remembering the incident that occurred earlier. "Are you still fighting with Yang?" Ruby asked hesitantly.

"I mean...I'm okay. I used my emotions constructively and did some training."

"Oh that's good, I'm glad you're so mature you know? You walked away from an unnecessary fight. I was worried with my sister's hot temper...you know?"

"Aww Ruby, I'm delighted to hear that. Don't worry. I don't think I'll ever be fighting Yang."

Weiss smiled sweetly, pressing her foot more harshly on the Blonde's head. Yang whimpered in response.

"You say something?" Ruby asked.

"Nope."

"Hey...listen I'll talk to Yang okay?"

"I..." Weiss paused, getting an idea. "I see that you are trying to help. So why not? I appreciate that Ruby."

"Great!"

"One last thing. There's a convenience store on the way back right? You haven't passed it?"

"Mmm...Yeah I passed it already, you need something?"

"I've been kind of tired. I was hoping you would get me one of those energy drinks."

"You know those are horrible for you right?"

"Says the one who has 5 sugars with her coffee." Weiss teased.

Ruby giggled over the phone. "You got me. I'll pick them up for you."

"Thanks, what would I do without you?"

"Oh you know I'd do anything for you Weiss. Plus, honestly I can't judge. I'm having cookies right now. Let's splurge together today. I'll save some for you too."

The sound of Ruby's laugh was enough to make Weiss's heart throb. It's like the two spent toys in front of her weren't even there.

"Sure. See you soon.~"

"Bye~" Ruby responded cutely.

'She seems okay now.' Ruby thought with a relieved smile.

Weiss threw her scroll to the side, her smile fading immediately.

"You stupid slut. You used up all our time that we were supposed to be using for planning." Weiss said to the helpless blonde beneath her.

"Mph...Nnn..." Yang let out her muffled voice, unable to speak.

"Okay bimbo, your sister is going to talk to you later. You're going to take all the blame for our little fight and apologize to me. Okay?" The white haired dominatrix asked, not letting go of the pressure on her foot

"Mphhh Mphh." Yang tried to speak again.

"Pathetic. Answer. Me. Properly." Weiss said in a slow condescending tone, emphasizing each word as she used her foot to roll Yang's head to the side a bit. Now that she could speak, Weiss pressed her foot on Yang's cheek and waited. Yang gasped, catching her breath, her face still flushed from fatigue.

"Y-Yes mistress. I'll do it. I'll tell Ruby." She muttered. She paused, continuing after a moment of thought.

"You have something to say? Say it." Weiss commanded.

"Ruby...What will you do to her exactly?"

A tear seemed to build up on Yang's face as she thought of her sister. Even now, the girl's protective love seemed to fight her influence.

"You seem to be struggling. If you hadn't wasted so much of my time, we might have managed to plan something. What I do with Ruby is not something you should concern your little slutty self with unless told by your mistress, Me. You don't ask the questions here. I do. I know it's not your strongest skill, but try to listen. More importantly, I hate that guilty look on your face. That is not good at all..." Weiss finally let her go, pleased with Yang's quiet meek little nod that she gave in return. It was only hours ago that the girl dared to stand against her. Now she was going to do anything she wanted. And such a wonderful idea just popped into her head.

"Let's do one last thing before Ruby gets here."

Weiss heard the door open with a click, and she turned her head.

"Guh...H-Help" Ruby muttered as she struggled to push the door open, awkwardly holding the doorknob.

"Bwaha. You dolt! Just ring the doorbell next time." Weiss said, shaking her head with a silly laugh as she rushed over to help.

"Thanks Weiss. You're the best!" Ruby thanked her as she used Weiss's arm for support as she passed a few bags of groceries.

The small inkling of warmth and skin to skin contact from Ruby seemed to just electrify Weiss. Weiss blushed a bit, unexpectedly taken back from how much it affected her.

'D-Did I really just get aroused just from that? Even after all I did with this two. What the fuck Weiss. Keep it together. It's only a matter of time until YOU FUCK HER BRAINS OU-'

Weiss forced her thought to stop and she felt a jab of pain in her head. She slowly exhaled, wincing.

"Is it too heavy?" Ruby asked, seeing Weiss's discomfort.

"No...I'm fine." Weiss reassured her, turning around and bringing the bags to the kitchen.

Things were getting harder to control. She could feel it.

"Where's everyone else?"

"They're upstairs. Let them spend some time together."

"What are they doing?"

"Uhhh..."

Weiss's tone was enough for Ruby to blush and regret her question.

"N-Never mind!...Ew...Ew. Ew. Ew. EW!"

Weiss smirked at that, turning to look at Ruby.

"Hmm? Something wrong? What did you think of?" Weiss asked an obviously feigned ignorance, a sly smile on her face.

"Maybe I'll go and eat cookies by myself." Ruby jabbed back at her teasing.

"Okay, I'll stop. I'll stop. Haha" Weiss said with a laugh, covering her mouth.

'She's way too fun to tease.' Weiss thought, licking her lips as she put away the groceries.

"Alright, enough of that. Let's finish putting this away and make dinner?" Ruby suggested as she followed.

"Yeah."

Yang was trying her best to get up, struggling to even do that.

As soon as they heard the door open it seemed to get even worse.

"Ruby's here huh?"

"Hnn~..." Yang moaned cutely.

Blake purred, looking at Yang. Yang was clenching her first, shivering as she tried to keep herself together.

"You're like this even after all we did together? Maybe Mistress went overboard with that last part." The Faunus said as she combed her hand through her hair, crawling on top of her and pushing her down.

"We have some time. Let me try to relieve you a bit, maybe you can at least be a bit more presentable...for your sister." Blake whispered in her ear, feeling Yang shudder against her.

"Blake..." Yang moaned breathlessly.

"I know babe...Let me take care of you. Just try to be quiet." Blake whispered back.

Ruby hummed as she finished up cooking, and Weiss stared at her in awe of her beauty.

Ruby stirred the stew they were just about finished making, glancing over and catching Weiss staring.

"W-What? Something on my face?" Ruby asked innocently, scuffling her nose to see if she could feel anything there.

"Uh..No. No."

"You've been spacing out a lot lately. I don't know what exactly happened between you and Yang, but don't worry about it. I'm here for you."

"You worry about me?"

"Of course I do!"

Weiss started to blush, trying to find words. Her heart seemed to melt. A heavy guilt seemed to creep its way to the surface. It was such an obvious thought, but it seemed like her mind pushed it away long ago.

'Am I really going to do those things to Ruby?'

DING!

Weiss jumped at the noise and yelped.

"Pfft. Ahaha. Sorry. Sorry." Ruby couldn't help but laugh, covering her mouth and muffling her laughter once she saw Weiss's annoyed face.

"Oh har har." Weiss said, rolling her eyes as she turned off the stove.

Dinner was ready. It was time to call the others. Weiss smiled realizing what fun was to come. Whatever doubtful thoughts she may have had was drowned out by the excitement of playing with her new toy, Yang.

Dinner was progressing smoothly, Ruby and Blake were chatting and nobody seemed to notice Yang's odd quiet demeanor. Weiss took another spoonful of soup, her cold gaze staring at Yang expectedly.

Yang met her eyes for a moment before looking down at her food; taking a small bite with her spoon as she twirled her hair nervously with one finger. Whatever conversation was happening between Blake and Ruby was not even registering in Yang's mind. In fact she was trying as hard as she could to ignore Ruby's voice. Just hearing her voice was making her body react in ways she never wanted it to.

'I just...need to handle this until dinner is over. It'll be okay.'

"Remember that time Yang?" Ruby asked after turning to Yang, nudging her with her elbow to get her attention.

"Hnnmph~" Yang made a strange noise, a perplexed look falling on Ruby's face. Blake just hid her smile, turning away, her cat ears perking up excitedly.

'I just came with Blake and I'm already like this just from her nudging me...' Yang thought in shamed horror. 'I can't let her touch me again. I won't be able to hide it...'

"Uhh...You okay?" Ruby asked with her eyebrow raised. "Did I scare you?"

"T-The soup is just hot. I umm...sorry I didn't hear what you said Ruby. I was distracted." Yang said, forcing a smile as she glanced at Ruby. Her eyes falling on her sister's deliciously beautiful complexion was almost too much. Her face looked so adorably cute and she just- 'What the fuck...Stop Stop Stop.' The blonde begged herself in her mind.

"You sure you're okay? You still hung up on our fight." Weiss asked, feigning innocence. But Yang could feel the sadistic undertone.

"I..."

"Yeah c'mon sis, Weiss said everything cool. It's just some stupid fight. Right?"

"Yeah Yang, she forgives you." Blake added.

"N-No...it's not that. We're okay...We're okay right Weiss? Weiss..." Yang asked. Ruby had no idea what she was really asking for. Her voice dripped in desperation. She was pleading for mercy from this sickening curse.

Ruby had never seen her sister like this before, and she was even more confused.

"Of course we're okay. I love my friends way too much to let something petty get to me." Weiss answered in a seemingly genuine voice. "Maybe she's feeling unwell?" She added.

"Is the food making you sick?" Ruby asked, leaning forward. Yang certainly didn't look too well by the looks of it. It was like she could barely sit upright.

"You should check her temperature Ruby." Weiss added. She had to cover her mouth with her hand, barely able to keep herself from grinning.

"Ruby...Wait...S-Sis..." Yang's voice was breathless. Weiss could see her trembling slightly. Surely her naive sister didn't see this as anything other than signs of sickness. But everyone else at the table knew the truth.

Yang felt Ruby's hand rest against her. Yang shut her eyes tight and clenched her teeth as hard as she could.

Ruby was so close to her, she could smell the lingers of her sweet scent from here. She felt her pussy burning up. This empty needy feeling filled her very core. It was like her loins were on fire at the mere thought of Ruby, and now this was just turning that spark into a blaze of infernal heat.

She exhaled, doing everything she could to stop herself from screaming, stop her from losing her mind, stop herself from showing Ruby how much she wanted her.

'Cumming...' Was all the blissed out huntress could even think of as she felt her body shiver, leaning into Ruby's arm as she hung her head.

"You don't feel like you have a fever, but you're shivering. If you felt sick you should have just said something. Aren't I supposed to be the little sister here?" Ruby teased.

'Best stop this before even the dolt suspects something.' Weiss casually prepared to undo the trigger.

"You okay Yang, you trained hard today right? Maybe don't push yourself so hard." Weiss suggested. Yang looked over and their eyes met again. This time Weiss licked her lips in front of her.

That's all it took.

Yang felt like she could breathe again, her head was clearer. It was a simple and inconspicuous activation.

Yang was still riding post orgasmic aftershocks, but the single moment of clarity was all it took to feel disgusted with her. She just climaxed from her sister's scent, her warmth, her lightest touch. It was like her entire being was sexual need, a sexual desire for Ruby. Weiss had made it so.

Now she was in her soaked panties, she was sure she squirted straight into them in that blur of pleasure.

The worst part is, she was rewired to Weiss's liking in more ways than just that. Weiss may have lifted the incestuous hypnotic suggestion with that last snap. It was just one small switch hidden inside her. Many more were constantly there, unbearably intact.

As much as she felt she should hate Weiss for how she's being treated, just thinking about how sadistic she was being towards her was melting her heart. It was like she had found solace in the worst way possible.

"Yeah...just a leg cramp. I just needed to stretch." Yang forced herself to respond, playing along with Weiss's statement.

"Didn't I tell you to stretch after working out?"

"S-Sorry..." Yang answered timidly. Ruby was taken back at her gentle feminine voice.

'When did Yang act so feminine?' Ruby thought to herself before Weiss broke the silence, keeping her from reading too much into it.

"Well I'll help you stretch next time."

Yang stayed quiet for a moment, giving one simple nod. "Y-Yes M-...Weiss...That sounds great." Thoughts flooded of what that truly meant, her body responded quickly, heating up again.

"Aww, Yang you don't need to be all shy about getting along with Weiss again." Ruby said with an innocent smile, completely misunderstanding the situation and giving a small giggle at the end. "Who knew my sister could be so cute."

Yang felt her conscience eat away at her. Through all the filth forced into her mind, she felt 1 strong thought trying to force its way through her, despite every hypnotic suggestion from Weiss. She needed to warn Ruby.

"Ruby... I need to tell you something."

Weiss's eyes creased immediately. With an annoyed face she started to lick her lips in a slow insidious way. Yang noticed and forced herself to look away.

"Ruby, I-

"Yang." Weiss said in a commanding voice.

Yang looked at Weiss, her head shaking as she struggled not to.

"Yang, what's going on?" Ruby asked, not following what was happening at all.

Weiss finished licking her lips and smiled at Yang.

Yang shivered. Vivid images of incestuous sex filled her mind. Stronger than any desire she ever had with even Blake. No, that wasn't the comparison to make anymore. In this moment, the unbearable need was even stronger than her attraction to Weiss.

"Go on Yang, explain." Weiss said, casually eating another bite as she waited. Yang's eyes met Weiss's, as her body trembled.

That cold heiress's gaze cut into her like daggers. And she shook her head, trying to deny her feelings, feeling them overtake her.

"DONT TOUCH ME!...I-I'm sorry."

"Sis? You're kind of freaking me out." Ruby's voice was clearly worried.

Yang couldn't bear to look at Ruby. She forced herself to look at Weiss with pleading eyes.

Weiss licked her lips again, getting a spoon full of food immediately after as she silently chewed, watching Yang closely as she deactivated the trigger once more.

Yang exhaled, feeling a rush of relief again, but also fear.

Weiss was merely toying with her. She couldn't say anything to Ruby. Not while she was around. And she just showed her disloyal intentions.

"My stomach hurts. I think I'll skip dinner after all and rest." Yang said, smiling reassuringly to Ruby. She paused, resisting the urge to say something else. But Weiss's intimidating presence stopped any attempt to do more.

"Okay...get well soon Sis." Ruby said a bit perplexed by her reactions today.

"Yes, you wouldn't want to let it get worse than it already seems to be. It would be careless."

Weiss's words cut into her.

"Y-Yes, you're right Weiss."

"I'll check on you later and bring you something easy to eat." Weiss said with a sweet smile.

Yang nodded quietly and scurried off.

The 3 chatted normally for a few minutes, but as dinner went on, Weiss found herself intoxicated by Ruby. More so than usual.

'I wonder if this is somewhat like Yang feels like.' The white haired huntress thought to herself with a smile.

It was this moment that Ruby had turned her eyes to her.

"What's so funny?" Her red haired friend asked, grabbing Weiss's hand. But Weiss wouldn't respond.

Even if it was faint, her silver eyes had glowed. And Weiss's body felt like it was burning from the inside. She clenched her teeth and pulled her hand back.

She looked down to see the ring glowing an eerie red for a moment, as if it was fending off something.

Ruby had touched the ring.

Weiss's smile faded and she hid her pain, just shrugging off the question.

'This didn't happen before...Why?...Fuck that hurt.'

'She'll be dangerous if you don't do something soon.'

It was all too clear. That foreign thought in her mind was merely warning her to act. She didn't like being commanded, but it just so happened that she didn't mind this one thing. Whatever this ring was, she'd deal with it in time.

'Stay out of this...'

'Hahaha...You won't be saying that soon.'

'What do you mean?'

'You'll see.'

After dinner Ruby checked on Yang, who quietly reassured her that everything was okay. The odd timid nature of her sister made her doubtful, but Yang wasn't one to lie to her. She sighed, trusting her to sort it out.

'I love you Yang. Get well soon."

"I love you too sis..." Yang said weakly.

When the door closed her eyes started to water. She didn't give in to the tears and stayed strong.

One suppressed voice echoed in her mind. An irresistible command she knew she had to do.

'Do it at midnight.' Weiss said to her, handing her what looked like an EpiPen.

Yang nodded obediently, excitedly accepting her task.

"You touch her in any way or do anything I didn't tell you to. You'll regret it."

"I-I wouldn't..." Yang said with a blush.

"Good girl."

Ruby was sound asleep in her room as Yang stood above her. The drug in her hand shook with her trembling nervousness.

'I have to do it for my mistress. I have...but why? Why am I hesitating so much?'

Ruby looked so peaceful in her sleep. Yang felt her body heat up at the sight. She blushed in shame. 'I can't even look at her. I have...I have to hurry up before I do something wrong.'

Yang's thoughts made her hasten, but this doubtful feeling made her stop just short of pressing the injection on Ruby's thigh.

Beyond this foreign inkling of arousal there was something more pure. She closed her eyes, pushing the thoughts away.

"No..." Yang said audibly, holding back her hand with her other hand. She drew her hand back and bit her lip, shaking in resistance.

Ruby stirred awake, wincing as she opened her eyes. Within Ruby's calming gaze it was like everything became clear for a moment. And a moment is all Yang needed to find herself once more.

"Yang?" Ruby asked in dazed confusion.

After a moment of silence, Yang decided what she would do.

Yang grabbed her and pulled her up. They both were still in their pajamas, but they didn't have any time.

"We have to go. Now. "

Thank you all for waiting. I was unable to write for a long time. But things are changing. I have very good news. I should be able to write the next chapters a lot more quickly. The situation has been getting better. I hope you all enjoy how things unfold.

Let me know what you think! Next chapter should be out soon this time. Do you think you know what will happen?
