Nose torture is a traditional Japanese form of BDSM. There are various forms of nose torture. The most common involves the application of a hook, known as a nosehook, which is inserted through the nose and pulled backwards. The harder the nosehook is pulled, the more painful the nose torture.
A victim of nose torture typically experiences physical pain and humiliation. When nosehooks are used in nose torture, the submissive partner is known as a nosehook slave.
