With her slave bound in four point restraint, Princess Karlie installs a dildo head harness on her slave and an electric ball crusher. She wants this to be all about pleasure for her and pain for him. She mounts the dildo as she slaps, crushes, and shocks his balls. She is clearly getting turned on watching her slave suffer as she rides his face. Karlie grabs the Hitachi and pleasures herself to orgasm.
