With the basics.

The way Melanie said those words actually raised some concern in Yang. She was far too confident for someone whose only control over someone else was ****. Granted, as far as **** material could go, Ruby was absolutely the worst thing for her, but still.

Melanie took out her scroll and tapped a button. From around the smooth metal collar, a soothing tingling sensation began to spread. It flowed up to her head, and down throughout her entire body. The feeling was not entirely uncomfortable, and she had to concentrate to keep her guard up, lest she was caught unaware. When the sensation filled her entire body, it began to pulse once, twice, thrice, before rushing back into the collar.

A sudden coldness filled Yang's entire being. It was gone! The warm comfortable presence of her aura. The smouldering embers of her semblance. It was all gone, no matter how hard she tried, she couldn't feel it anymore. She looked at Melanie and her shock must have been clear to see, as the other woman gave a short chuckle.

"Handy little gizmo, isn't it? It was made by the Shnee cooperation to keep their rowdier indentured servants in line. While that collar is active, you can't access your aura. So no more super healing. No monstrous strength. Just one helpless...powerless...brat."

Yang's mouth opened and closed in disbelief. She couldn't believe it. She actually couldn't. She knew Melanie wasn't lying, she had been trying to activate her semblance all this time, to no avail. How could such a thing exist? Her shock slowly turned to anger, and she balled her fists, ready to lunge and punch that smirk on Melanie's face.

"Aaahhhh. Hah."

An unmistakable moan of pleasure, followed by a short gasp made in Ruby's voice had her stomp down on those thoughts. They still had her sister. First, she needed to get Ruby away from this place, then she could concentrate on levelling this wretched club.

"It's happening again. Please may I?"

Ruby's pleading had Yang turn to face the window, catching a glimpse of her sister's predicament. Ruby's gag was loosened and hung around her neck, allowing her to speak clearly once more. Miltia was rapidly moving her hand back and forth between Ruby's legs. From the brief glimpses she caught, she could make out that Miltia was using two fingers to thrust in and out of Ruby's pussy. And clearly, her sister was reacting to it, as she had a good guess what "it" was. Her guess was proven correct when Miltia spoke up.

"What's happening again? Say it as I taught you. Or do I need to repeat the lesson?"

Ruby arched her back until the sharp rattle of the chain connecting her collar to the floor snapped tight. Her legs and arms shook as she tried to maintain the strenuous strapado position, while also fighting off the shocks of pre-orgasm pleasure. Her mouth was open in a silent scream, and her silver eyes stared vacantly ahead of her. Miltia removed her fingers from Ruby's pussy, and the sudden absence caused her to shock back into reality.

"Nooo! Why did you stop?"

Miltia leaned closer so she could look the young huntress in the eyes.

"I stopped because you didn't say it as I instructed. I stopped because you were going to, despite not having gotten permission yet. I stopped because I absolutely love that cute and **** pout you get whenever I do it. Now say it properly."

She pushed her fingers back into Ruby's pussy, and quickly worked up a pace that had the younger woman squalling and pleading.

"Aaahh. Cumming! I'm going to cum again. Please may I cum?"

Miltia remained silent, and Ruby continued pleading, repeating over and over that she was going to cum. When it sounded like she really couldn't take any more, she relented.

"Fine, I think you have said it enough times now. You may cum."

With a final thrust deep into her pussy, Ruby convulsed as a long and loud scream of pleasure escaped from her lips. Her hips jerked and rolled, and the chains on her wrists and collar rattled with each powerful shock as her orgasm rolled through her. A full minute later, Ruby finally stopped screaming, and all a wide-eyed Yang could hear was her beloved little sister's panting breath.

"Thank you."

Yang could feel a presence step up behind her, and she could feel Melanie's warm breath tickling her ear.

"I know you enjoy watching your sister perform, but this is also about you. It's time you start earning back what you owe us. Your first task is a simple one. Strip."

It was like a bucket of cold water was thrown in Yang's face. A part of her always had an inkling something like this was going to happen after seeing what they did with Ruby. But to hear it said out loud was another thing entirely. Her eyes bore into Melanie's and her body visibly vibrated with barely suppressed rage. But the constant stream of moans and pants coming from the speakers reminded her of her situation, and how helpless she was at this moment. Slowly, she reached for the zipper of her jacket and pulled it down.

Despite her rage, she averted her eyes as she let the jacket slip off her shoulders. It slid down her arms, catching briefly on her gauntlets, before a shake of her arms had them come loose, and it fell to the floor. With two practised movements, the clasps of her gauntlets became undone, and they also fell to the floor with two loud clanks. Next were her boots, and she had to bent over to get them off, giving Melanie a nice look down her cleavage as the simple crop top did little to hide anything. With two thunks, her boots were tossed to the side, and her socks followed soon after. She grabbed the button off her top, and for a moment, hesitated before looking through the window.

Ruby was squirming on the stage, with Miltia using one hand to finger her pussy, and the other to play with Ruby's pert breasts. The moans and sheer bliss in Ruby's eyes made Yang sick, but there was nothing she could do right now. She balled her fists around the fabric of her top and pulled it over her head, before tossing it to where her boots and jacket already laid. The action revealed a functional bra that was designed purely to support her ample breasts in combat, not to look beautiful or enticing. If only it wasn't pink. Melanie laughed when she saw it.

"My my. Who would have thought that the rough and tumble Yang Xiao Long wears such a cute and girlish pink bra? Tell me, does it match your panties? Oh, wait, you don't have to tell me. You're going to show me."

Yang closed her eyes, body shaking in barely suppressed rage. Oh, how she wanted to punch Melanie's lights out. But without her semblance and aura, that was no longer an option.

"Ooh, I'm cumming again. Please may I cum again?"

Ruby's pleas helped ground Yang at the moment and kept her priorities. Instead of giving in to her rage, she reached for the belt of her pants and undid it. She undid the buttons and began to lower her pants. All the while, Ruby's pleading for permission to cum filled the small booth.

"Hmm. I don't know. I feel something is missing... Oh, I know. Call me Mistress, and I'll allow it."

"Please Mistress, may I cum. Please Mistress please."

Ruby's pleading was so **** and sincere that Yang was surprised that that was her little sister speaking. She barely recognized the person as Ruby. She pushed her pants over her firm ass, and lowered them all the way down, bending forward as she did so. When she got up, she kicked her pants into the corner with the rest of her clothes and stood straight. She now stood in front of Melanie in just her underwear, and just as the other woman suspected, her panties were indeed a matching colour of pink.

Melanie walked around her with slow deliberate steps, and Yang could feel her eyes lingering all over her body. Now Yang knew she was considered beautiful by many, and she had no qualms showing off a bit of that to tease or distract. But there was a level of vulnerability here that she was not used to. This was not her willingly shedding her clothes, but a **** action. And it made her all the more conscious of how she looked at the moment. Her cheeks blushed a shade of red she rarely had, and she moved her arms to cover her private parts as best she could.

"Cum for me. Show your Mistress what an obedient little slut you are."

Almost immediately, a loud scream of pleasure came from Ruby as her body shook and spasmed as yet another orgasm washed over her. When it was done, Ruby took deep panting breaths, before she managed to speak again.

"I'm not... I'm not a slut."

Instead of getting angry, Yang saw Miltia reach between Ruby's legs, and make a quick rubbing motion. Ruby tensed, and a soft moan came from her mouth.

"Oh, but I think you are. Just look at you, already moaning. I bet you can't wait for me to make you cum again. No, I think you are a slut. My...little...cumslut. Oeh! That sounds fitting, I think that will be your name from now on."

Miltia walked away from Ruby, and Yang saw her body slump against her bonds as the finger was removed from her pussy. Miltia walked towards a small cart standing off to the side, that she hadn't seen so far, and watched as she retrieved her scroll from it. She typed something on it, and on Ruby's collar, a black display sprang to life. Slowly, in bright white letters, a word began to form.

CUMSLUT.

The word was shown prominently on the front of Ruby's collar, impossible to ignore.

"Enjoying the show?"

Yang turned around and saw that Melanie had sat down on the couch. One leg crossed over the other, her pale green eyes staring straight into Yang's violet ones.

"Now as much as I enjoy seeing you in such cute underwear, I did order you to strip. So take them off."

Yang growled in anger, both from the sheer humiliation she was **** to go through, as well as seeing her sister behave in such a way. Her eyes slowly got the faintest traces of red, her anger so high that not even the aura suppressing effect of the collar could prevent it all. She took a deep breath, before calming herself, and spoke in an eerily calm voice that belied her emotions.

"No. This has gone on long enough. Release Ruby now, and you can both walk away with your lives."

Melanie simply stood there with a single eyebrow raised. After a second, when it became clear that Yang was not going to cooperate, she spoke to her sister once more.

"Sis, I think our beloved blonde bimbo needs another reminder of what kind of situation she is in. Would you be so kind?"

Before Yang could turn back towards the window, a sharp sound came from the speaker.

*TWACK*.

"Kyaa!"

Ruby gave a cute, high-pitched squeak. Miltia had picked up a thin bamboo cane and had brought it down hard on Ruby's behind. Already, an angry red line was showing on her two ass cheeks.

*TWACK*, *TWACK*, *TWACK*.

Three more were delivered with practised precision, and three more welts crisis crossed her otherwise flawless skin.

*TWACK*.

Another one was delivered to the inside of her thigh, dangerously close to her pussy. Each time she was hit, Ruby Gave a yell as the sting of the cane came down on her unprotected flesh.

"I'm sorry mistress. I'm sorry. I don't know what I did wrong, but I'm sorry."

Miltia gently took Ruby's chin and turned her head so the young huntress's tear-filled eyes could look into other own.

"Oh, cumslut, it's not what you did wrong. It's what someone else didn't do. Now be brave, I'm sure it will be over soon, and we can go back to more pleasant things."

There was a short swishing sound, followed by a *TWACK*, and a high scream from Ruby. This time, the cane had struck her on the underside of one of her breasts, and the soft mound swung wildly from both the impact, as well as the sudden shock Ruby made in pain.

In the booth, Yang could only watch in horror as her sister was being struck again and again. Small red welts began to cover her body before she saw them slowly start to fade as a ruby red glow covered them.

"Yeah, we didn't have to block her Aura? She's such a natural submissive, that she obeyed us the moment we placed the collar around her delicious little neck. Miltia had her eating from her hand from day one. And not just her hand, let me tell you. Now, I assume even your dumb brain has gotten the idea. So unless you want to continue seeing your sister suffer, I suggest you do as we say for the time being."

Seeing how Melanie was right, how Yang saw no way around her current situation right now, she did the only thing she could; Continue to undress.

Slowly, her hands reached behind her back and began to undo the clasp of her bra. She heard Melanie tell her sister to stop, and thankfully the sharp sound of the cane never came again. Though it was quickly replaced with the soft hum of something and a quick moan from Ruby. Staying focused on her job, she slid the straps of the bra off her shoulders, and let the piece of underwear fall to the ground.

She saw Melanie lower her eyes to fully admire what was just revealed, and her face burned with humiliation. Melanie gestured with a hand, and the silent command was clear; Keep going. She hooked her fingers around the waistband of her panties, and after taking a deep breath, pushed them down, before stepping out of them.

Yang was now fully exposed. All her clothes lay on the ground around her. From her trusty gauntlets to her most intimate underwear. She was totally naked, and when she felt more than saw Melanie's eyes roaming across her body, she instinctually raised her arms to try and cover her private parts. Melanie's hands shot towards her with surprising speed, and she pried Yang's arms away. Only when she tried to resist did Yang realize how truly helpless she was without her aura.

"AAhhh. Oh, Mistress, I'm going to cum again. Please may I?"

Yang saw how Miltia had taken a wand vibrator and was holding it against Ruby's pussy, causing the red-haired woman to squirm and squeal in place.

"Hmm. Not yet. Count to ten, and then you may."

"One..Two...Three... Please, Mistress."

"Keep counting cumslut, or I'll remove it, and I know you don't like that."

"NO! Don't stop. Four...Five...Six...Aaahh...Seven... I don't know if I can do it, Mistress."

"You can. And you will, because you won't like what happens if you don't"

Yang saw the struggle on Ruby's face. The pleasure threatened to overflow only held back by Ruby's willpower. She knew how strong the vibrations from such a toy could be, and she was frankly amazed that Ruby had managed to last this long.

"Oh. Please please, please. Eight...Nine...TEN."

"Very good cumslut. You can cum now."

Ruby outright screamed as the **** of her latest orgasm tore through her young body. The chains holding her in place rattled as her entire body strained against their limited slack. As a final show of how strong her orgasm was, a spray of clear liquid shot from her pussy, creating a small dark puddle on the stage. When her orgasm was finally over, Ruby's heavy breathing filled the booth, and Yang stared wide-eyed at what she had just seen.

"See. Behave, and do as we say, and you will be rewarded. And trust me, your rewards will be much more pleasant than your punishments. As dear Ruby can attest to. Or I guess I should call her cumslut now. But, even though it took you a while, you are appropriately dressed now, so let's get on with the real fun, yes?"

Even though Yang had a pretty good idea of what Melanie meant, she still shivered in both fear and anger. But the cold absence of her aura had her realize she truly had no other choice than to follow their orders.
