Mouth corset from Top to Bottom Leathers[ext]
A mouth corset is special type of neck corset, designed to also cover the wearer's mouth. They are primarily used in BDSM, because they can be used as gags.
Incorporating a gag into a neck corset presents a few safety issues: should the wearer begin to choke, it is not easy to remove the gag quickly. For this reason, most mouth corsets use a simple muzzle gag that merely covers the mouth and does not force anything into the mouth, thus minimising the risk.
Despite not forcing anything into the mouth, mouth corsets are usually very effective in gagging the victim. This is due to the fact that the chin piece prevents the wearer from opening their mouth and dislodging the gag, and the lacing at the back of the corset holds the gag tightly against the mouth, making a very effective seal. In addition, it compresses the wearer's cheeks.
