If she is comfortable with it try blind folding her.....it will heighten her other senses and help her trust you with new ideas.... And the key is to go slow, and use a lot of positives. Like how amazing she is, and how excited she makes you feel. Also ask her if she is enjoying it. This should really be all about her and teasing her. Line up things to use.....could be fruit, syrups, feathers, flowers, vibrator, lotions, lubes, etc. have a game plan in place so you have an idea of each step your going to take. Start with her clothes on (button down)but as your going through teasing her...... Work her out of her clothes. Start with teasing her taste buds, even if you just try that much and she gives up control to you, you will get her hooked. Then the next time you could try something a little more adventurous.
