Nun
From wipipedia.org
Nuns are members of an enclosed monastic order, nuns traditionally wear a garment called a habit. Nuns will take vows of sexual abstinance and chasisty.
The fetish world has taken the image of a nun and perverted it, the fetish nun is now as much of an icon of sexual perversion as a real nun is of sexual purity. A number of Fetish Designers have takne the theme of the nun and produced their own take on the nun's habit in latex and PVC. Fetish nuns are a common site at clubs.
