Oh man, that's tough with limited relationship info.... you gotta keep all your stuff on the home turf advantage. Only you know her and can detect her comfort zone. You could tell her you have a sensual gift for her but that puts you in line to find her a bbc... or you could offer her a sensual night out for Christmas if she has a sexy friend who'd enjoy exploration with her but be ready for her to say unexpected answers with questions about WHY she's given such and offer. You know her.... we don't so go with your gut feelings. Mine softened up about a strip bar night out and she was open to online videos to get the interest up... either way, good luck to you. A word of caution, if she gives you that look of "are you testing me"... show her that is a genuine offer for her pleasure and be completely at ease with any answers she give... enjoy!!
