using ropes to fix a person into a position, where their movement is highly limited.
Tethering is generally the use of ropes, to limit a submissive's movement.
However, other devices of restraint can be used, to hold a person in place, such as straps, leather strands, chains, etc.
Improperly securing the rope, or other material, can result in injury to the submissive.
Can be where the 'rope' is used to join the submissive to other restraining devices, such as cuffs, or hooks.
Used mainly in Bondage sex games, and in Suspension Play in the BDSM community.
