White (undyed, unscented) candles burn at a lower temperature. She should be tied down. Start by holding the candle about a foot above her, then lower an inch at a time until you begin getting a reaction. The first couple of times you'll need to rely on her to let you know when you've gone too low.

You can probably wax anywhere except around the face. Note that wax in hair(s) can be a bitch to remove. Stay away from the stereotypical erogenous zones for the first few minutes -- kind of spiral in on them. Remember that if you're waxing an area that already has wax on it, you can go lower, because the older layer will act as an insulater.

Oh, and DO NOT use the barrel-shafted candles (the ones that collect a pool of wax) until you're ready for more advanced play. Use a tapir (tapered candle -- like one that goes in a holder for romantic dinners). You can always masturbate her with it when you're done. (Or stick it in her rear while you fuck her.)

Last point, put a beach towel or extra sheet under her, because this can be incredibly messy. By the same token, keep a glass of water handy in case you drop the candle and set something on fire.

Enjoy!
