Fortunately for Yang, no

"Fuck" Weiss repeated as she relaxed her grip on Yang and stroked her head "Good job to be your first time, pet"

"Thank you Mistress." Yang smiled shyly at the congratulations.

"Get dressed and ..." Weiss ran a finger across Yang's face, picking up her juices and bringing it to her mouth. Yang hesitated for just a second before eagerly licking Weiss's finger as she smiled, pleased. "Wipe your face, you don't want your little sister to see you like this."

Yang nodded as she continued to suck, grateful that Weiss won't expose her to Ruby and Blake.

When Ruby and Blake returned they found Weiss with her notes and Yang in bed playing her videogame.

During the rest of the day the team continued its normal activities. Weiss with her usual cold demeanor, Yang a little less energetic. Please Weiss had left her horny and confused.

She didn't consider herself submissive, much less bisexual. But she had gotten wet being used as a mere sex object.

"HA! You bite the dust again Yang!" Ruby exclaimed cheerfully.

"Pff yes whatever, it was a practice game."

"Ajam, the third one isn't?"

"Yang wants to bite something else." Weiss casually intervened without looking up from her notes.

"YES! Wait... what?" Ruby looked confused at Weiss and then at an increasingly flushed Yang.

"Yes, what does that mean Weiss?" Blake joined the conversation, looking up from her book.

"It means I'm hungry! We're all hungry, right?" Yang looked pleadingly at Weiss.

"Sure. What else could it mean?" Weiss nodded even without looking up.

Ruby screamed and ran off to find food. Blake looked suspiciously at Weiss and Yang but shrugged and closed her book to head to the dining room with her team.

Yang sighed in relief but knew she would have to "thank" Weiss later.
