She wants to go through with it

After thinking about it for a few moments, Ruby met Yang's gaze and shook her head.

"No," she said firmly. "No, I want to do this."

"Are you sure?" Yang asked

"I'm sure. This whole bet was my idea, and I should see it through. Besides, like you said, the three of you will be right there, with me."

Yang smiled and patted Ruby's shoulder. "I knew you had it in ya. Nothing can stop the silver-eyed hero of Remnant!"

Ruby smirked at the comment and took a step forward, wrapping her arms around Yang's waist and burying her face in Yang's shoulder.

"Uh...Ruby?" Yang said after a moment, caught off guard by the sudden contact. "You know we're both...naked, right?"

"I know," Ruby nods against her sister. "But...we're both girls. We've been seeing it for weeks, now. What's the harm?"

Now it was Yang's turn to realize that Ruby had a good point, and she returned the hug, resting her chin on top of Ruby's head.

Roughly an hour later, Weiss and Blake woke up, too. They all went through their morning routines and, once Ruby and Weiss were all showered and dried, the time had come. All four girls stood in the middle of the room, Blake and Yang opting to remain naked for the painting process.

"Alright," Weiss sighed, looking down at the paint in the winners' hands. "Let's get on with it."

"Aw, what's wrong, Weiss?" Yang laughed. "Not feeling excited?"

"I think she's feeling very excited," Ruby teased, smiling at her partner.

Weiss blushed and looked away for a moment, mumbling "dolt" under her breath.
