Chapter Text
The black book sat innocently on the desk. It had no title, the cover instead bearing a pattern. It was a nice pattern, if a bit… esoteric. That was one of the reasons Blake had bought it after all.
While picking up her Ninjas of Love order (volume 63 had promised some really spicy work), she had spotted the book behind the counter at the bookstore, and had asked about it. According to the owner, the book claimed to be a spell tome, but she had said that it didn’t work. Blake had then asked if she could have it, the human easily agreeing and ringing her up for it on the spot. Even gave her a discount for ‘making it so I don’t have to organize it anymore’.
While Blake did want to get back to her smut, the book warranted an investigation.
“After all, magic isn’t real…” she muttered, opening to the first page, and a foreword.
Inside this book are spells, for the manipulation of minds and bodies. Should the reader find these distasteful, then they should know this tome is not for them-
“Hey, wait a second.” Blake’s ear twitched.
The rest of the foreword was a lot of words to say a whole lot of nothing, so Blake flipped pages until she came across something more interesting.
“A hypnosis spell?” According to the book, all she had to do was, while holding the book, look at someone and ‘concentrate mentally’ upon them while saying their name and the command. It sounded completely out there.
It was a good thing she had an… ideal target.
————————
“There’s no way this is going to work…” the cat Faunus muttered to herself as she watched her target.
Finding Cardin was surprisingly difficult- the guy didn’t seem to go many places. Of course, getting on the wrong side of Coco Adel wasn’t likely to make one the biggest of socialites, but she still expected him to at least be outside somewhere.
Luckily, she did find him in the dining hall, reading a book as he ate lunch. She never pegged him for a studious reader, but appearances could be deceiving. Taking her own seat at a nearby table, she flipped the black book open to the hypnosis ‘spell’, putting her finger on the page and staring at Cardin. While she’d been looking, she had pondered on what ‘concentrate mentally’ meant, and decided to try flaring her Aura.
“Cardin.” She started. Black tendrils encroached on the edge of her vision. The armored man suddenly sat ramrod straight, the book he’d been reading falling to the table.
Blake blinked. It was….. working?
“Uh… You’ve had a change of heart lately. Faunus aren’t playthings to be mocked and bullied, and you truly feel sorry about your previous actions.” As she finished speaking, the black tendrils at her periphery vanished. Closing the book, she decided to test the hypnosis by walking by his table.
“Uh, hey, er, miss cat girl?”
Blake had to pause for a second. While the wording was… questionable, the tone really did sound apologetic.
“It’s Blake, Cardin.” She said, turning around to face him.
“Right, sorry. I didn’t know your name, just uh, just your features. A-anyways, I uh, wanted to apologize for the uh, really really dumb stuff I said. I’ve been doing some thinking lately and realized that, well, Faunus are just people too, y’know? So um, I’m really sorry and I understand if you still kinda hate me.”
The Faunus blinked. Then she sighed. “Not right now… but you’re off to a good start.”
Then she turned and hurried off, hugging the book to her chest, mind racing.
It worked.
———————
Once again, the black book lay open on the desk in the dorm room. Blake’s mind raced at the possibilities just mind control opened up to her. She flipped the page, wanting to see what else the book could offer her.
“Body modification… breast expansion… fertility heightening… futanarization?!” She muttered, each spell seeming more fantastical and debauched than the last. She knew the mind control spell worked, but for all she knew, it had been a fluke. She needed another way to test this!
That way was shown to her in the form of her team leader, Ruby Rose.
Blake liked her team leader- she was positive (sometimes annoyingly so), a ray of sunshine she sometimes wondered had decided to take a human form. She was also incredibly skilled, a downright prodigy when it came to combat. She was also decently smart, if a bit forgetful and easy to distract. And she also loved running. To an unhealthy degree. Blake liked to jog every morning for exercise, of course (and her own fighting style did rely on being mobile), but Ruby did full on laps around the entire Emerald Forest for fun. But that was just the things that Blake liked about her. Her body, well…
Blake really liked that about her. If Yang was any indication, Ruby was nowhere near done developing. Even still, her chest was quite noticeable, contained and pushed up by her corset (‘COMBAT corset!’), while her skirt flared over hips that were already wide and an ass that, while not quite as nice as their ice cold teammate’s (and definitely not even on the same level as her, to borrow a phrase from Yang, ‘Bellabooty’), still looked quite full and spankable. Her legs definitely showed her dedication, being lean and supple while still having a hint of fat and a bit of squish at the top of her leggings. And of course, she was cute enough to be utterly sexy- she looked like an innocent maiden that one of her smu- ROMANCE novel heroines would introduce into a life of debauchery.
“Hey Blake!”
“Hi Ruby.” Blake instinctively made the book harder for her team leader to read over the shoulder, looking back as she jogged into the room. As much as Ruby loved going at full speed, having to go any slower than what a lot of people considered running was practically impossible for her. Thankfully, she went over to her dresser, allowing Blake to quickly flip to the body modification she wanted to test.
Ruby was a growing girl, after all. What harm would a little… extra growing do her?
Once again, Blake flared her aura, this time staying quiet so that Ruby couldn’t hear her. The spell also didn’t require talking, that she knew of (obviously the hypnosis spell did, though it apparently didn’t need to be audible to the target, if her hypnotizing Cardin in the loud cafeteria was proof enough), so she watched her team leader as the black tendrils once again appeared at the edge of her vision.
Ruby had removed her school top, probably to go shower (after all, if one wanted hot water, they had to claim the shower before Yang), and was unhooking her bra. Just as she got the clasp detached, her breasts sagged just a touch heavier. Slowly, they crept outward, Blake watching raptly as another inch was added to her bustline.
“Man! I really wanted a practical Combat class today! Maybe I’ll go to the forest later and do a bit of clearing out?” Ruby said, almost to herself. That distracted Blake enough that she let go of the book, the tendrils receding as Ruby’s boobs stopped growing. They had to be at least a cup size or two larger, now definitively bigger than Weiss’ pair. Ruby picked up a copy of her outfit, then walked into the bathroom and shut the door.
Blake was stunned. Not only did hypnosis actually work, but the book on her desk was proof that magic really existed.
And she’d found it in her local bookshop.
…what was she going to do with it?
—————-
The answer to that, seemingly, was to try it on herself.
That night, now that she knew her teammates were asleep, she pulled the book out from under her pillow, and leafed to one spell she knew that, if it worked, she had to experience, at least temporarily. She flipped to the proper page, quickly checked to see if her teammates were asleep (Yang, she didn’t even have to look- her chainsaw snoring had kept her awake for a week until she got used to it), then flared her aura, staring down at her crotch in excitement and building lust.
A lump formed on her pelvis, just above her labia. As the spell continued, the lump began to lengthen, forming into the familiar shape of the head of a penis (Blake would know what they looked like- despite never having seen a real one, Ninjas of Love was quite ‘anatomically correct’ with their katanas). She kept the magic going, stifling a moan as her new cock continued to pull further out of her hips.
As the spell went on, her cock rapidly began to change. Instead of being shaped like a human penis, it more resembled a cat’s, being pink in color and sprouting spiny nubs along it’s length as it continued to grow. A small sack began to grow at it’s base, two testicles dropping in to fill it as it began to inflate. When Blake finally dropped the spell, a full foot of spiny, cat Faunus-cock stretched from her waist up to nearly her collarbone. A fat, round sack, maybe the size of small oranges, hung underneath, resting lightly on her lower lips. Satisfied, she shoved the black book under her pillow, and began to experiment with her new penis.
Just rubbing it felt fantastic, the already hard cock sending tingles up her body as she stroked her hands up and down it’s length. Brand new nerve endings fired with the same, possibly better, responses as the ones she’d had since she was born. In no time at all, she felt a new sensation.
“Shit!” She hissed to herself, trying to think of a solution that didn’t involve a possibility of her missing a spot of cum somewhere. After a second, she just shoved her mouth onto her own cock, hoping her cumshot would be small enough that she could spit it into the toilet maybe.
The gush of semen into her mouth was more than enough to tell her that she would not be spitting the majority of it out.
Blake’s eyes widened as she hurried to start swallowing, the thick cum still attempting to fill her mouth up even as she gulped huge gobs down as fast as she could. Thankfully, her orgasm quickly died down, letting her take a break from swallowing her load before finally getting it all down, and allowing her softening cock to droop as she let it go, huffing as quietly as she could to try and bring her breathing under control.
‘Holy shit, that felt incredible!’ The feline Faunus thought, gazing down at her cock, before suddenly falling back onto her bed like a puppet with it’s ropes cut. A sudden wave of exhaustion had blown through her, and she was only barely able to slide underneath her sheets before she passed out, unaware of the book underneath her head that would soon change her life irrevocably.
