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.
