Yang couldn't possibly refuse

Before Yang could respond, Weiss groaned.

"Really, Ruby?" Weiss complained.

"What?" replied Ruby, innocently.

"Does that really seem... appropriate to you?"

"I think it's a little late for that!" squealed Ruby, pointing at her own completely unclothed body.

"Hmph, fair point." Weiss said, before folding her arms in front of her bra and turning her head away. "I just think there are some lines that maybe team mates shouldn't cross."

"Suit yourself," said Ruby before turning to look at Yang, "now then, are you going to do the dare, sis?"

"I'm game," Yang began calmy, "how about you, BB, are you ok with it?"

"Yeah, sure." Blake replied as casually as she could manage. "And you'd better make this good, you owe me for daring me to strip naked last round."

"Right then, let me just get a timer ready to go on my scroll," said Ruby, "Ok... hey, I didn't say go yet!"

It had only taken Ruby a matter of seconds to find her scroll, but by the time she had Yang and Blake had already gotten started. The two girls were kneeling next to each other. Yang had one hand on Blake's hip and one gently grabbing her ass as she kissed her. One of Blake's hands was stroking Yang's hair, while the other was drifting suspiciously between her own legs as she kissed back. Ruby waited a moment for them to stop, after all she had just warned them that she hadn't started timing yet.

"For god's sake, you two, fine then, the two minutes starts now!" said Ruby, mildly angry when they did not stop.

The two girls briefly stopped kissing for moment as they couldn't help but giggle at their inability to wait. They continued making out for the whole two minutes.

Weiss had looked away for most of the event, but couldn't help looking for the last 20 or so seconds.

"Wow, they are really going at it, huh?"

"Yup." said Ruby.

"Isn't this a bit weird for you, sitting here naked, watching your older sister make out with your friend?"

"Yup."

"You're really not very good at this game, Ruby."

Ruby glared at Weiss.

"Thank you for stating the obvious. I really hope I get to give you a dare next round, Weiss." said Ruby, with a slightly evil smile.

"I don't know if I should be more terrified or turned on." said Weiss, Ruby continued to just smile at her.

A ringing noise finally broke up Blake and Yang's kiss as the four girls prepared to draw the order for round 4.

Round 4 order:

#1 - Weiss

#2 - Blake

#3 - Yang

#4 - Ruby
