Conflicting Personalities (from a prompt given to me by reddit user ASouthernRussian)
Blake, combing her thick, black hair before the mirror above her desk, examined her uncovered pair of cat ears. It was unfair that she was born a Faunus; all things considered, it had brought her nothing but trouble, and benefits of improved hearing and better night vision could never offset the troubles of her youth. With a sigh, she set down the comb, figuring her hair was as nice as it was going to get, and stood up.
She had not so much as started to turn around when Yang suddenly hugged her tightly and kissed her on the lips. Though Blake knew Yang's affections to be those of a teasing sort, she could not help but to enjoy the soft, moist heat of Yang's lips against her own.
"Hey, Blakey," Yang said, releasing her friend after a moment, "Ruby, Weiss, and I are going to go into town for lunch and shopping. Do you want to come?"
Blake thought for a moment, distracted by Yang's purple irises. "No," she answered in her quiet, unemotional voice. "I'd rather stay here. But can you get me some more tuna?"
"Sure thing, little kitty," Yang said, scratching Blake's secondary set of ears with her hands. Blake, blushing hotly and suppressing a purr, brushed Yang away. "Please stop."
"Not on your life. Oh, and since you're going to be the only one here, I need you to watch Zwei."
Blake, appalled by the idea of spending an afternoon with that thing, made a face of pure terror. "Wait, you didn't -"
"Okaythanksbye!" Yang interrupted, zipping out of the door with the remainder of Team RWBY, leaving a traumatized Blake standing paralyzed in front of the small dog, who gave a single, happy-faced bark as he stared at his afternoon caretaker.
"Don't look at me that way," commanded Blake to Zwei, who continued to look eagerly at her. She figured that, as long as she kept to herself and read a book, that Zwei would leave her well enough alone. So - keeping a far away from the small dog as possible - she navigated to her bed, picked her book off of her pillow, and jumped nimbly up to Yang's bunk.
The smell of Yang's hair permeated the sheets, and Blake soon found herself too preoccupied enjoying the scent of lavender shampoo to start her book. Another bark from Zwei broke her from this small trance, and reminded her she had a book to read. She stretched out on her belly, holding her book in front of her, and tried to pick up where she left off.
But, with the relentless gaze of Zwei's happy face locked on to her, she could not bring herself to read so much as a single sentence before succumbing to her irritation. Why do they have to leave me with that mutt, thought Blake, turning to glare at the small animal, they know I don't like it.
Zwei evidently did not share her sentiments, and - with another happy bark - leaped up to face Blake, who - confronted by the object of her disgust - launched herself to Ruby's bed in terrified surprise. "Stay away from me!" she shouted angrily at the dog. Zwei whimpered in response, his happy face morphing to one of incredible dejection, and buried himself in Yang's covers.
Satisfied with the resolution of this conflict, Blake began to read, finding herself finally able to focus.
After about fifteen minutes of Zwei's continued whimpering, Blake finally found herself beginning to be distract by a feeling of sympathy. She chose to ignore it. But, at more time passed, the sensation grew, until finally she had to leap back over to the head Yang's bunk with a sigh. "Zwei," she said tenderly, her human instincts overwhelming her feline aversion, "I didn't mean it. Come out." The little dog refused to move from the small bundle of blankets he had created at the foot of the bed, but had stopped whimpering. "Zwei, really, just...get over here," she pressed, daring to set a tender hand on the lump of dog and blankets.
Zwei slowly moved towards Blake, poking his head out from beneath the covers and staring up at Blake when he finally managed to untangle himself.
"I'm sorry Zwei, you don't have to hide from me."
Each step filled with hesitation, the dog inched his way towards Blake, eventually sitting down before her and making an inquisitive whimper.
Blake, still feeling some revulsion towards the small canine, laid a hand on his head and patted him twice. "I guess you're a good dog." Zwei's face lit up in happiness, and with a joyful bark, leaped into Blake's lap. Though she nearly threw Zwei across the room, Blake managed to contain herself, and began - to her own surprise - to pet the little dog. Zwei responded by pressing himself closer against Blake's legs.
Figuring this position was as good as any, Blake held up her book in one hand and read, still petting Zwei with the other.
Several hours later, Ruby, Yang, and Weiss all noisily entered the room, hands full of shopping bags. Blake, absorbed in her book, failed to notice until Yang shrieked, "Blake! You - you and Zwei!"
Blake humphed inquisitively, still focused on the text in front of her.
"You and Zwei are - getting along?!"
Blake looked away from her book for a moment to look at the napping dog in her lap. "I suppose we are."
She had no time to react before Yang pounced upon her and crushed her with a tight embrace. "Awww, that's so cute! I'm so happy you finally realized what a good dog Zwei is!" Blake, trying hard not to blush as the smell of Yang's hair filled her nose, hugged Yang in return and pulled her down next to her on the bed. "Stop doing that," she demanded calmly.
Yang, blushing herself, laughed. "Looks like Blakey is feeling a little frisky."
"Oh, shut up," Blake said, uncomfortably aware of Yang's warmth. "Did you have dinner yet?"
"No, we were coming to get you and Zwei."
"Alright," said Blake, letting her lips briefly touch Yang's cheek as she sat up. "Let's go then. Come on, Zwei."
The two girls and the dog awkwardly made their way off of the bed, and with the other two members of Team RWBY, walked out of the dorm room.
