Product Testing: MidNite Fire is a line of lubricant that not only tastes great but has the property of getting warm when you rub it, and warmer still when you blow on it. (FYI: It's the carbon monoxide in your breath that causes the heat.) Some women have reported using it as a late-night lip gloss while they "apply" it to their partner. Others, knowing how visual men are, have put it into their mouths and then "applied" it by leaning over his genitals and letting a thin, slow stream of the lubricant flow onto him as he watches.
