A great post!...and good advice. Myself I don't drink booze anyway and I do think you'd be better of not risking it.
The implement of choice is an important consideration *only* in terms of how you want to go about things. Starting with something familiar and easy to use is the best bet. A hand works well. A leather belt?
I think part of what you're asking is how you as the top or Dom will 'get into it'. Different people have different triggers or different persona or whatever. You'll find yours. The tip on talking I think is brilliant (I like to talk while topping anyway) because it allows you to experiment a bit with different types of scenario. Is she going to be naughty and need a spanking/caning? is it that she is a slut who will want to beg? Is it that she is so horny she needs a nice strapping to help her control her desires? All these are questions (and more you can think up) you can whisper in her ear (or shout as the urge takes you) as you're building things up - your own reactions and her responses could be a good guide as to how you want to play it out.
I think even if she is a pain slut you'll still want to discover your 'motivation'.
But get in close and get your own arousal working to overcome those initial jitters.
Most of all - don't be intimidated by the experience. Easy to say but we all go through it. Do as much as your comfortable with. Regardless of her possible reaction I'd say you're better off going a bit soft rather than too hard. Don't think you need to impress her. Its about safety for you both.
Enjoy it!
