to relax - via sexual intercourse, the use of a
dildo, fist, or other object - an anus to the point where it will remain open, at least for a short while, when the
penis or
dildo is removed. This is a desirable goal in certain kinds of fetishist anal play, e.g. the open anus is considered visually exciting, or it can be urinated in, used during scat play, etc. Sometimes "medical" devices, such as a speculum, are used to keep the anus open for similar purposes.
