Chocolate syrup can be bad... my experience with it wasn't as fun as I had hoped. He massaged it all over my body, and licked it off intermittently. However, once all was said and done the chocolate had dried and I was stuck to the towel we had laid down! It hurt like a bitch to take it off too... not fun. So I would suggest using it in small areas, and licking it off fairly quickly. Don't want her sticking to anything... it kinda ruined the whole food thing for me. But good luck!
Edit: And be careful with honey... I have heard horror stories of people using it to spice up oral sex, but then when they got to the real sex there was still too much there and they stuck together! And they said it was painful to pull apart. Definitely a mood ruiner.
