"L" is for Leather Butt

[gracieflower]

Leather butt - 1) A term that describes a person who has been beaten so often that only intense whipping has any effect. 2) The condition of the buttocks after heavy paddling. The skin compresses and becomes stiff or -leathery' to the touch. The compression effect is most pronounced with paddles. so leather butt can be avoided by using a mixture of implements.

Or Leather as in the Leather community (or Leather-men as it's also known) who in large part are credited with the beginning's of bdsm in North America.

There are also several varieties of the leather fetish in which its all about the smell, feel, and sometimes taste of it, not to mention it looks down right cool and often scares and perhaps in some cases entices the vanilla's lol.
