I should consider the possible audience. If it's for a general audience, the story needs to be more about character development and setting, avoiding explicit content. Focus on Vicky's interests, her hobbies, perhaps her hobbies that involve German culture, her unique traits. Kinky could mean she's unconventional, maybe into something like leatherwork, or has a vibrant personal style. Maybe she's a leather artisan in a small German town, which creates some tension between her personal style and the conservative community.
