Armbinder

This VN contains at least one scene involving sexual activities practiced while one of the characters is wearing an armbinder.

An armbinder is a type of restraint devices primarily used in bondage play (rather than law enforcement, medicine, or psychiatry), designed to bind the arms and/or hands to each other or to the body, usually behind the back, and employing a range of bondage equipment including cuffs, rods, straps, and gloves.

Often referred to as a single glove or single sleeve, the monoglove is the most prominent example of a class of restaints called armbinders that are used in bondage.
