Yuki glared at the pair, furious at the guy for grabbing her and locking her arms and legs in shackles, but even more angry that he had the nerve to use her piercing kit and give that sister slut of his the piercings that she was going to give to her own bunny slave!  "Damn you!  Let me go, and stop using my piercing kit!  I swear, when I get out of here I'll kill you and take your sister as my new slave..." she growled, her tail swatting the floor angrily as she tried to work her hands out of the manacles, having no luck whatsoever.
