You gently run your hands through Weiss' hair and she rests on you. You'd found some time to spend with just her after everyone else was occupied with something else; Yang was still enjoying her alone time at your apartment for another day, Ruby was off doing some leader-only training, and Blake had decided to take her own time as well. This was now a rare opportunity to spend alone with Weiss. While no part of you was upset with dating four gorgeous and sexually active women, there was a special intimacy when it was just you and her. You hope to make one on one time for everyone, but you'll let the chips fall for the moment. Now that Yang was part of your… yeah, it's a harem at this point. Now that Yang's in, you'll have to spoil her as you did with everyone else, as well as properly inaugurate her once she was ready to have sex.

For now, though, you've just enjoyed your time sitting quietly in RWBY's increasingly familiar room. You and Weiss had been bumming around the past hour, her in her nightgown and you enjoying her in her nightgown. Though you didn't feel sex coming, you'd still teased her plenty enough to confirm that the heiress, like many women, didn't wear a bra to bed. In addition to feeling her up every now and then, the slight, SLIGHT transparency of her nightgown clued you in that she was also wearing a cute pair of striped panties. Life was good.

"I was thinking," Weiss says to the air. Though she was resting on your shoulder, she didn't direct it to you specifically; she left her words to the open air, almost more of a venting of frustrations. "The other day, in class, Pr. Port was… well, being Pr. Port, so I was doing my best to listen. I drifted in and out since I went over most of what he pretends to teach back at home in my private studies, but I did key in on something."

"What?" you ask, also to the room. Something felt right about it.

"He mentioned that certain types of Grimm have strange powers. Like, of course some are more dangerous in general, but others have odd properties that make them more specialized. Almost like a species-wide Semblance."

"And what's so interesting about that?" Even as a star student, Pr. Port's lectures bored Weiss enough to slack, so he must have said something specific to catch her attention.

"Well, he mentioned a few. There's a rare insect-type that drains energy, possession-types like my… well, my summon would be one once I can control, it. And then he mentioned one that got me a little… excited." Weiss puts a hand to your chest and leans in closer. "Excited," was her way of saying horny seeing as she was still on and off about sexual language.

"Go on?"

"Well… I remember Ruby showed me one of those kids movies about a thief boy in Vacuo. It's a bunch of storybook nonsense, but the antagonist almost took control of a kingdom by… well, he hypnotized the princess and almost forced her into marrying him." Weiss starts pushing her head into your chest, brushing herself. "In the movie, he just had magic powers, but… Port mentioned that there are Grimm capable of soporing people's minds. Classes have had me a little stressed lately, so I thought… maybe it might be nice to… you know, not think for a little moment. Just let someone… let you tell me what to do."

Man, the world is awesome. Weiss' current fantasy is to be put under!? That's yet another dream come true. But wait… "How do you… Can you do that? How does hypnosis work anyway?"

Weiss pauses, a little embarrassed. "I did some cursory research. No one is able to just control somebody outright like in the movie, obviously, but there's all sorts of tricks to it to increase… oh, what was it…? Suggestibility! I think I might be able to bypass most of them with a Glyph, and then give it to you."

"And you're sure about this?" As amazing as the opportunity was, Weiss was offering you the chance to essentially control her. While you imagine she wouldn't do too much she wouldn't do otherwise, your limited knowledge of hypnotism leads you to believe she'd be willing to do what you say since she trusts you so much.

"Well… no. I'm not sure I'll be able to do it properly; I've never attempted a Glyph that would affect a person's mind like that. I'm not even sure it would work." Weiss looks at the ground. "Ideally, I'd like a… well, 'test subject,' makes it sound sinister. I suppose I could try it on you to see what happens; I THINK I can at least make you a bit more docile."

As if on cue, Blake slides soundlessly through the door. "I'd be willing."

Weiss, surprised by Blake's sudden appearance, covers her chest, hiding her almost-visible breasts before remembering that Blake wouldn't mind. Relaxing, she says, "You need to knock. Even if we are together, it's still a good idea."

"Eh, I heard you talking and decided a dramatic entrance was fitting."

"You heard her?" you ask.

Blake raises an eyebrow and removes her bow. Fiddling with her ears, she explains, "You REALLY have no concept of Faunus differences. Admittedly, those with ears can hear significantly better, but all Faunus have improved senses. I know how to block things out, but I was listening in to decide if I wanted to get involved or if it was better to head to the library."

"You don't have to eavesdrop if you want to get involved…"

"More than once I heard you being all sweet and left you two to your own devices. Now that we're together, I listen in for any fun stuff~" Blake's tone causes Weiss to blush. "Anyway, I heard hypnotism and I am SO down."

Weiss blinks. You and her look at Blake, interested in her reasoning for why she'd be interested in hypnotism. "You… want to be my test subject?"

"Oh, PLEASE!" Blake says, with a genuine look of excitement in her eyes. "It's all over the place in my books, so I'm open to actually trying it. The thought of having my mind go blank while you have your fun… honestly, that REALLY appeals to me. You… I trust you can figure out why."

You look at Weiss. She knew about Blake's abusive past and all the baggage that came with it. It made perfect sense that somebody with so many demons and under so much stress would want to enjoy a few minutes without worry or thought. If Blake was offering, then hypnotizing her might be the perfect thing to do. You and Weiss nod at each other.

"Okay, Blake. I'll be willing to try it on you if you would like."

Blake nods and looks at you. "And if we're going to… I kinda want to… can we…" She stops speaking and goes over to her drawer. Fiddling around, she withdraws the collar you bought her, the one you use/will use for pet play. "If this works… I want to be a little pet!" Instantly, Blake was a different person; usually, she had her quiet demeanor, but talking about this, she was like a child getting a new toy. "A cute little kitty!"

You see Weiss blush. She hadn't quite seen the extent of Blake's pet play fetish, but she seemed into it. She definitely hadn't seen Blake's enthusiasm. "I don't know exactly how it will work, but I think we'll be fine with that."

Again, in a manner not much like her usual self, Blake pops over to you and removes her scarf. Exposing her neck, she hands you her collar and requests, "Put it on, please! I've been wanting to play~"

Feeling your erection strain, you place Blake's collar around her neck. Though she could do it herself, it was a sign of deference that she'd let you make her your pet. Plus it let you sniff the light fragrance in her long hair and breath softly on her neck. You get her started on her excitement and wonder how long she's been aching for this; you had just had an orgy with Ruby, but she seemed more than ready for sex.

"Are you ready?" Weiss asks. When Blake nods, she takes a breath and focuses her Aura. A purple glyph appears around Blake's neck, much like the collar she was wearing. As it begins turning, you see Blake's eyes start to lid until she looked ready to fall asleep; with her eyes half shut, her mouth fell open like any effort was too much to put into keeping it closed. By all accounts, Blake looked like she was a mindless drone of some kind.

"I… think it worked," Weiss said, looking nervously at Blake. She waves a hand in front of her face, which Blake lazily follows. "Blake, are you there?"

"yesssss…" Blake says, lazily drifting out the words. Her expression remained unchanged.

You look at Weiss and shrug. Deciding to test where Blake was at, you say, "Blake, you are a cat."

Slowly but surely, Blake's hands roses until she tucked them in. She softly began pawing, occasionally saying, "Meow…" in a airy voice. Turning to Weiss, you nod at Blake, inferring that her hypnosis seems to be working.

"So… I guess we just continue. She shouldn't do anything that Blake WOULDN'T do without convincing, so…" Weiss looks at Blake and says, "You… want to let me scratch your ears." She sounds a bit guilty, as Blake was still in and off about her ears being touched. As Blake lowered her head and began purring, Weiss learned that she was alright with it in the right situation. The white-haired girl slowly raises her hand and starts playing with Blake's ears; the Faunus coos and meows pleasantly, drawing her body closer to Weiss as she enjoys her mindless pleasure. Weiss immediately blushes bright red, finally afforded the chance to pet Blake's ears.

As Blake straightens out and smiles, you look at Weiss. Once again, you wish to test Blake's hypnosis. She clearly was in the mood to fool around, so you press your luck and say, "Blake, cats don't wear clothes. Undress."

"Yesssss," Blake says, starting to warm up. Though her eyes were still lidded, she was expressing more emotion now that her hypnosis was starting to set in. She begins unbuttoning her jacket, then pulling it off. Though a bit clumsily, Blake starts undressing as you and Weiss watch with bated breath. At no point does she stop or object, so you feel no need to hard cut this. Still, as she pulls down her shorts, you tell her, "You can stop there," leaving her in her bra and a thong, along with her thigh highs and boots; the hypnosis clearly clouded her mind, so she'd removed her top and pants, but not her shoes or wrappings. It was INCREDIBLE to have Blake standing before you in her underwear with a collar on; today's ensemble was black with some pink trim, the thong having a little flower on the center. God, Blake wearing such skimpy underwear under her battle outfit turns you (and Weiss) on, and adding a mark of subservience…

As Blake stops, you and Weiss almost geek out. The ability to hypnotize was definitely an exciting prospect, especially if she was this receptive. You tell Weiss, "I'm going to tell her to go outside. If she tries, I'll stop her, but I want to check if she's limited." Weiss nods, so you raise your voice and order Blake, "Walk into the hall." Though you'd LOVE to parade around Blake in a thong, you know she wouldn't be down for that, at least not without a MAJOR conversation beforehand going over boundaries.

Thankful you decided to push your limits, you watch as Blake starts struggling with herself. In her dazed voice, she moans out a, "N-no!" while her body starts to turn towards the door. Even though her movements are stilted, it's clear that the part of her in control is striving to not take another step. She doesn't want to go outside, but her body is making her.

Knowing you'll never be forgiven if you force Blake to flash the school, you say, "Stop!" before she gets more than a few steps. As Blake stops moving, you turn to Weiss and say, "Undo it. We know that we can go too far, so we better make sure she's okay."

Weiss, clearly a little too excited about the prospect of exhibiting Blake, removes her glyph. "At least she's herself. We know that the person will say no, so we'll know if we're doing something that they wouldn't want."

Blake's sense quickly return to normal as she recovers from her hypnosis. She takes a moment to understand that she was in her underwear. Though she blushes a bit, bye sheepishly says, "That was… Wow…"

Letting go of her girlfriend, Weiss asks, "What? Did you like it?"

Blake pauses. "I… Yes. That was… oh, wow. That was something else. I was just… sitting there, letting my body do what it wanted… No thinking, no worrying, no… Wow…"

"So you're okay with it?"

Blake meets Weiss' eyes. "I LOVED it." She looks at you. "But who do you think you are, asking me to go outside like this!?" She motions to her thong and angrily pouts. "That's a hard no! I felt like if I struggled enough, I could stop, but I will NOT be showing everyone my panties!"

"I wanted to check if you were still in control, I promise!" you say.

"He's telling the truth," Weiss says, saving your life. "We learned that, yes, you'll let us know if we're making you do something that you don't want to do. Unless you didn't what to strip for us?"

Blake calms down and flaunts her underwear-clad body. "No, I was down to do that. Not down to show Jaune my ass anytime soon, though. First rule with this kind of thing, and I mean, seriously, NEVER hypnotize someone without permission, and ALWAYS listen to when they say no."

"Of course!" Weiss says. "This is the first time I've tried it, so it's actually good we discovered what it's like. I promise I won't do anything like that without permission! So... would you like to keep going?"

"Oh, god, yes! Do whatever you want to me!" Blake says, almost jumping. "As long as we stay in here, just treat me like a toy! It's like, I get to just let my mind go blank while I feel… like, I just exist to feel good! I'll be your perfect little kitty cat!" Without hypnosis or provocation, she bats her hand like a cat, a smile stretching across her face.

"I promise to never do anything like that without permission again. Yeah, we just needed to know in a controlled environment." Blake nods and accepts the reasoning, allowing you to stare at her breasts without her arms angrily crossed over them.

You and Weiss look at each other and nod. It was time to release Blake's inner beast. With a wave of her hand, Weiss applies another hypnosis glyph to Blake's neck, transforming her into a welcoming kitten. This was going to be VERY enjoyable.
