An enema is the simple task of putting water up into the anus to clean out any remaining fecal matter in the bowel. Water is pushed up into the rectum and then as it mixes with the matter that is present, your body then flushes it out into the toilet for disposal. When people have severe problems with constipation, an enema might be administered to help relieve the discomfort and eliminate the blockage. While a medical solution to begin with for many people the act of the enema is a truly arousing and intoxicating fetish.
