Blake strolled calmly down Beacon's halls, it was dark, and there were few other footsteps to be heard. Occasionally a single figure on a moonlight stroll or a giggling couple might softly pass by her in the twilight, but nobody paid her any attention. They couldn't see that the school uniform skirt she was wearing was more-than-slightly too short, or that the blouse hugged her curves and accentuated her cleavage. They probably didn't even notice that the glasses she wore were made more as a fetish toy than to help her read. Blake had perfect eyesight. This was the time when herself and the other girls prowled the floor, going from room to room, satiating the carnal lusts of everyone that ordered them.

Ordered. Off a menu. It was disgusting, demeaning, depraved. It was why Blake enjoyed it so much. This pastime that had developed into an obsession had started simply, much like most of the other girls now feeding their hunger for it. First it was just small gropes and kisses from Yang and Pyrrha while studying, a scratch-my-back-I'll-scratch-yours deal. Then when she started finding herself horny she became a little more... public. It became pretty much an open secret that Blake's perpetual offers of study dates was simply an excuse for her to sleep around.

So when The Mistress' little prostitution venture had popped up she was one of the first to sign on. Most of the girls just saw an opportunity for sex and easy money, some even described getting their brains fucked out as liberating, but for Blake it was the opposite. The money was a nice bonus, sure, but what she really saw was the ability to go beyond what she could do with a conventional partner. The process was a fantasy come true for her - the demeaning undertone of 'the whore' that pervaded all her sex was euphoric. She enjoyed being treated like she was owned and then fucked like an animal, faunus rights be damned.

This fetish was why Blake was so eager to reach her next caller. At the door she knocked and when the boy nervously let her in she strode through the room, locating the bed.

Ignoring the solitary student, she climbed on top of the bed covers and laid stomach down on her knees, bringing out a book on Grimm anatomy to leaf through before pushing her rear up and presenting to the space behind her, well aware that her ass and panties would avoid being covered by her scandalously short skirt. Ignoring her own provocative pose, Blake began reading about the reproductive habits of Grimm mammals, praying that her gentleman caller would understand.

Apparently he did, because a few seconds later, while examining the male beowolf's genital anatomy with lusty longing, Blake felt a hand stray across the underside of her lacy black panties. Quivering in anticipation she moved her rear into the hand, trying to get more friction across her pussy, only to feel the boy's face press against her crotch through the panties. He was teasing her, and her subconscious submissive streak was preparing her to be fucked - her cunt was already thoroughly lubricated.

"Let's get rid of these, shall we?" The boy said from behind her, while Blake simply purred as he pulled her panties away and giving the barest degree of friction against her vagina. Noticing, he cupped a hand over her cunt and began to gently masturbate her. "You're a horny kitty, aren't you? I'm gonna enjoy fucking your ass. But first I'll make you squirm." He leaned down and planted his lips to her crotch, before starting to eat her out aggressively.

Her book forgotten, Blake dove her head into the pillow, her sensitive pussy exploding with pleasure from the student's delicate mouth. She had been eaten out before, but never in a way so dominating, she was in bliss, but was barely using his tongue, when he wanted her to meow sexily he brushed a lip against her clit. He reached up and started groping wildly at her large breasts, jiggling in her lingerie.

When he decided he had enough of pleasuring Blake, he jabbed his tongue into her and gave a long lick upwards. The motion was more than enough to cause Blake to cum and she squirted all over the bed sheets in the same moment that he tore her blouse off her and unclasped her bra, letting her breasts spill out into his hands. The minor acts of dominance she used to initiate this had been obliterated and she was his to command.

He unclasped his pants quickly and began to drag his long, thick, cock across Blake's cunt, causing her to moan and purr louder. Blake hardly knew how she still had the capacity to notice, but it didn't feel human. He'd probably been a 'victim' of one of Weiss' ministrations. She had been getting progressively more bold with the cosmetic modifications she was 'testing' on the not-so-poor students that crossed her path. The boy preparing to rut her was apparently one of them.

She didn't care. She was willing to go through with whatever this boy wanted to do to her. If he wanted to rut her until dawn than so be it.

"What contraceptive are you on?" The boy asked, almost with a sneer, still teasing her taint with his bestial cock. The question made Blake's ears perk a little, but she just wanted to continue.

"I.. I use my aura." She let out between pants. "Please... Please put it in, I need it." It was almost a dumb question, any girl with half a brain knew that she could simply focus her aura on her womb to neutralise any sperm.

"Sure, just turn it off. Turn it off and I'll fuck you silly." It gave Blake pause for a second, but he was probably motivated as much by a desire to dominate as she was to be dominated - it was something she could deal with safely later. She unfocused her aura and started rubbing her glistening cunt against his cock. "Good girl," he said, reaching out and scratching her cat ears before finally thrusting inside her unprotected pussy, still wearing her skirt. She cried out in pleasure, relishing in letting herself being fucking like an animal. His cock certainly wasn't human. It had a tapered head, like a dog's or fox's, but whatever it was Blake was euphoric, she lived for every one of his powerful thrusts, squeezing her cunt tight around him lest he lose interest. His balls were large and pendulous and at the climax of every swing brushed against her clit, each triggering a mini-orgasm by itself.

By the time the boy finally came for the first time, Blake was borderline delirious and covered in sweat. But she perked up at the feeling of rope after rope of raw cum surge their way inside her womb, the boy held himself at the climax of his thrust and plunged deeper than before, his massive erection stretching Blake's cunt. The feeling was addictive, like she had just been exposed to a new drug she knew she would never give up.

All Blake mumbled was just barely a comprehensible "More... More..." Continuously. The boy obliged and began thrusting all over again. This time as they rocked back and forth Blake could feel the hot cum sloshing around inside her, the boy also began spanking her bare, large, ass in between thrusts, causing her to yelp in masochistic delight, and leaned down to whisper in her ear:

"What are you?" When she didn't understand he spanked her harder and repeated, "What are you?" In an agitated voice.

This time Blake understood, and cried out "I'm a bitch! A whore! A slut that just wants to be fucked!" Before orgasming and squirted again. He leaned back and ran a hand through her hair, gently. Before tugging it cruelly.

"Good! You're learning." This time as he came she purred affectionately and leaned back onto his cock, wanting to take all his cum, before de-mounting herself and turning around, squashing the boy's bestial penis between her boobs and smearing leftover cum over them or licking it up. Cum was an acquired taste, but she had certainly developed a dependence for it.

After that he came gigantically a third time, smothering Blake's entire face and cleavage before she set about licking it all up like a cat desperate for more cream.

Once she was done, the student was on the verge of sleep, so like an affectionate pet she laid him in his bed and gave him a gentle goodnight kiss, before collecting the lien he owed her and scampering away, clothed only in her skirt, abandoning her underwear and torn blouse.

It wasn't like there'd be anyone to see her.
