Her boobs, as usual

"Bounce your boobs for us!"

Yang glared at him, gritting her teeth

"I get that they're awesome but come on!" She protested, but her body obeyed. She began to thrust her chest in and out with force, causing her tits to bounce up and down with immense potency. To the point where, in fact, they started slapping her in the face every time they swung upwards, and smacking into her abs when they swung down.

"Oof... Okay that's en---ow! Enough! I don't want--ooh! To do this any-Gah! Anymore!" She whimpered.

Blake didn't say anything. She just sat there glaring at Silvanus with nothing but pure hate in her eyes. Though that hate went away immediately - replaced by shock when the command for her rang out.
