It began with a decision to sleep naked

Weiss walked back to her team's dorm room, having spent a long evening studying in the library. She was exhausted, and wanted nothing more than to just throw herself into her bed. She reached her room and opened the door.

"Hey team -AHH!" she said, gasping at what she saw.

Blake and Ruby were both under the sheets of their beds as usual, but Yang wasn't. She also wasn't wearing her pajamas. In fact, she wasn't wearing anything at all. Weiss looked up and down her friend's naked body, and couldn't help but admire her enormous boobs and curvy figure. But she still considered it inappropriate.

"Yang, what's wrong with you?" asked Weiss, putting her hand up to cover her view of Yang's body, hoping that Yang hadn't already seen her staring.

"Oh lighten up, Weiss," said Yang, "It's just a body, it's no big deal. And besides, as roommates we're all bound to accidentally see each other naked eventually."

"Hmph," said Weiss, unimpressed, "well aren't you going to put something on then?"

"Actually no." said Yang.

"What? Why?"

"This is a new thing we're all trying. I read online that it's good for you to sleep naked."

"Wait, 'all'?" asked Weiss, concerned.

"Yup!" said Ruby excitedly, "I'm naked under here too!"

"Me too," Blake added calmly as she briefly looked up from the book she was reading.

Yang climbed up the ladder to her bunk bed above Blake's.

"Come on, Weiss, you have to do it too!" said Yang, "We're a team remember, we do things together."

"Ugh, do I have to?" Weiss replied.

"Yes." said Yang sternly. "Don't worry, it's fine, it's really not a big deal."

"Fine." said Weiss, who promptly stripped to her underwear as she normally did, but instead of reaching for her pajamas, she moved her hand to unhook her bra. At this moment she realised her teammates were all watching her.

"Guys, can I get a little privacy please? You don't have to look!"

Now it was Yang's turn to look disappointed, but she obliged and turned over to face the wall, as did Ruby. Blake had the best cover as she simply raised her book in front of her face.

Blake sneakily peered over the top of the book and continued to watch Weiss as she quickly took off her bra and slid down her panties, before jumping into her bed, below Ruby's, and hiding her body under the covers.

"Night team!" said Yang, turning out the lights.
