Blake was curled up on her bed. Immersed in the new book she had bought that morning, when the door opened to emit Yang, team RWBY's blonde bombshell, just getting back from her daily workout.
As she sauntered in, she glanced over at Blake and stoped in her tracks. "When did she get so cute? I must get closer." She thought to herself.
So that was exactly what she did. She walked over to blake's bed and sat on the edge. When there was no protesting for her to get off, she slowly moved her way up the bed until she was lying next to blake with her head on her shoulder.
"What are you doing?" Asked Blake. "What, can't I snuggle with my favourite kitten anymore?" Yang shot back. All she got in response was huff and an eye roll. Yang took this as a good sign, and wiggled her way up a bit more until she could reach blake's ears, which were uncovered as they were in their dorm room. After doing that she waited a minute, so as not to annoy blake with her fidgeting, then slowly raised her hand towards the faunus's ears and gently scratched the base of her left one. When Blake didn't scold her, she lifted her other hand and did the same thing with the right ear.
As she continued to scratch the faunus's cat ears, she noticed that blake had abandoned her book in favour of butting yang's hands, just like a house cat. Yang found that she was extremely amused by this. All that amusement was quickly replaced by astonishment though, as yang heard that blake was now making a weird rumbling in her chest. All of a sudden she realised the rumbling was blake purring like a cat.
As soon as yang figured it out she said "Oh blakey you can purr! It's so cute!" as soon as blake heard this her face went the same shade of red as ruby's cloak. This didn't stop the purr though. Instead of sputtering and denying it, blake just leaned into yang and let the purr out fully.
This was the moment that Weiss decided to enter the dorm to study. She took one look at yang's grinning face, spun on her heel and left.
