Ruby and Yang

"Weiss!" Ruby called. "Hey, Weiss!"

Ruby and Yang strolled through the empty Dust Lab until they found Weiss's desk, filled with various viles of unknown Dust combinations.

"I thought she'd be here," Ruby said with a pout.

"She's probably off to lunch," Yang said, checking her watch.

"Any idea where she's eating?"

"Knowing her? Probably something ritsy."

Ruby groaned and sat down. She was hoping to squeeze in some some last minute team exercises for the Vytal Tournament, but there was no point in coming down here if Weiss was already gone. As she sat there, her eyes were drawn to a special vial that read, "DO NOT TOUCH." The Dust bounced between multiple different colors, each one captivating Ruby. Before she knew it, she was holding it in her hand. The warmth spread over her skin, making her tingle.

"What's that?" Yang asked suddenly.

Ruby gasped. She had been so transfixed by the vial that she had forgotten where she was. The vial danced out of her hands and towards the floor.

"NO!" Ruby shouted.

The vial shattered on impact, engulfing the two half-sisters in its aphrodisiac effects.
