She could still be completely vanilla, meaning having no interest in kinky behavior, but she might just want that extra little "spice". Maybe kiss her a little harder, act like her body is a drug and you are insatiable to it, and definitely talk dirty. You don't have to go all crazy, I think she just wants you to spice things up and try something new.
