A nose hook is a type of BDSM device commonly used in Japanese bondage, or shibari, and more broadly in contemporary BDSM practices. A nose hook consist a blunt metal hook which ends that are inserted into the nostrils of the person being bound, and pulled upwards with a strap that passes over the head and can be connected to a collar to maintain tension.
A nose hook may be used as part of humiliation play or as part of dehumanization. It may also be used as part of a predicament bondage scene or make bondage more uncomfortable or more strict.
The hooks pull up on the nostrils, giving the user an animalistic or porcine appearance which may add to enjoyment via erotic humiliation. The user may also receive pleasure via masochism, as the use of a nose hook may be painful depending on the level of tension applied. As a form of facial humiliation play, nose hooks are often used in combination with other BDSM devices that incite shame, such as ball gags, mouth spreaders, etc.
A sideways nose hook stretches the nostrils apart and sideways, with a hook on both ends of a strap going around the head.
