Persephone seems cold and unemotional to the point of being an ice queen, but she will warm up to those who take the time to speak and interact with her. This is also the safer approach as taking her off guard is a risky venture courtesy of her big guns. Her tight bodysuit nicely highlights everything, but one would have to be blind to not notice her wonderful chest. Use a tight shibari, focus on her breasts, and use any kind of gag that won't block the view of her hair. Get squeezy with her once she's helpless.
