I always love a good mystery, but this was ridiculous. The small bottle of China Brush has directions that say "Apply a thin layer of this solution to the penis immediately before going to bed." Why? Will it help me sleep better or what? Then, a cryptic warning screams (in capital letters): "DO NOT USE MORE. JUST A THIN LAYER WILL GIVE YOU THE MOST SATISFACTION." An additional sheet is written in Chinese; it looks like something you are supposed to chant to. With curiosity piqued, I decided to contact Nasswalk. When I finally got the company, a mysterious woman was put on the phone. She told me that the potion is a really good sexual stimulant. Just apply a thin layer. So I did. It works, but next I hope they'll invent an antidote soon that will help my hard-on go down.
