I was browsing through a Dominatrix website recently where I read that one of her interests included Omorashi. Being naturally curious about any and all fetishes out there I had to investigate...

The word rang a bell but had no clue what it meant. Turns out Omorashi is a popular Japanese fetish and is translated as "wetting oneself", usually in panties. In the West, the term pee desperation is most often used.

So people into this fetish get aroused by experiencing a full bladder and eventually having to relieve themselves in their undies, often in public. Or they love seeing someone else losing bladder control. Some are into diapers but most in regular underwear.

Not to be confused with watersports or golden showers. No nudity is required in Omorashi, and it seems this is how the Japanese get away with doing fetish videos on the subject.

You'll find a variety of Omorashi videos by doing a quick search using "pee desperation" or "omorashi", especially on You Tube.

One wiki article I came across offers much omorashi info and explains how even game shows are centered around the theme, such as having contestants guess which girl really needs to go to the bathroom. Would this type of game show be popular in the West I wonder? 

Anyway read the whole article here.
