Omorashi (or オモラシ in Katakana, おもらし in Hiragana) is one of the many fetish subcultures in Japan. Omorashi participants are sexually aroused by desperation caused by a pressing need to urinate. Some are sexually aroused by someone else exhibiting visible anxiety caused by an overly full bladder, others are aroused when they are the ones who have to go.
