Yang comes home!

Ruby kept up this pattern for the next few minutes. Technically vacuuming, but mostly getting herself off from the vibrations. As far as she was concerned, the rest of the world didn't exist right now. It was just her and this machine.

Which is why it was such a surprise when Ruby finished vacuuming and turned around to see Yang sitting on the couch, looking right at Ruby with a devious smile.

"Yang!" Ruby shouted, dropping the vacuum and hastily covering her body with her arms. It slid down the stairs with several loud thunks as Ruby tried to gather her thoughts.

"W-w-what...w-when...?"

Yang couldn't help but throw her head back and laugh at the ceiling, greatly appreciating Ruby's reaction to being caught.

"Oh, this is just great," Yang said once she got her laughter under control. "I never would've thought my little sister could do something like this!"

"Y-Yang..." Ruby began, still keeping herself covered. "T-This isn't what it looks like."

"Hm...yeah, I don't buy it," Yang says, standing up and folding her arms. "I got home about five or ten minutes ago, and I saw what you were doing to the vacuum. Speaking of..." Yang looked down at the vacuum, which had settled about halfway down the stairs. "If you're gonna do that, you should at least buy it dinner first."

Ruby blushed a deep red, averting her eyes for a moment.

"I, uh...I'm gonna go...get dressed," she said awkwardly, moving up the stairs.

"Oh, no you don't!" Yang said, moving to the bottom of the stairs. "You're gonna stay like that, for now."

"What?!" Ruby asked, her anxiety mixed with anger for a moment. "Why would I do that?"

"Well...if you don't, then I'll just have a conversation with Dad when he gets home," Yang said, pulling her scroll out of her pocket. "And I think he'd be very interested to see some pictures I took..."

Ruby's jaw dropped.

"You didn't..."

"Oh, but I did," Yang laughed, clearly very proud of herself. "You can get dressed when Dad comes home. But until then, you're gonna stay naked. Deal?"
