Yes, she does

Yang pulled out her scroll and began to record.

"Hey guys!" she said in a voice that sounded a bit too artificially chipper. "Yang 'Big-Titties' Xiao-Lang here!"

She turned and bent over so her ass faced the camera, before pulling her cheeks apart. "Everyone always says how big my boobs are, but nobody ever talks about my ass. I mean, it's smaller than my honkers, sure, but look at that jiggle."

To demonstrate, she smacked her ass, sending a ripple through it.

"Mmmm, don'tcha like that?" Yang purred huskily. "Don'tcha like it when I smack my big ol' ass?"

She turned back around and began to grope and jiggle her tits. "Or maybe you prefer my tig old bitties? My body was maaaade for fucking."

Jaune couldn't believe she was actually doing all this. This meant he was probably safe to fuck her and the trance wouldn't break.
