The definition or description of Bondage in Wikepedia. 

Bondage is the practice of consensually tying, binding, or restraining a partner for erotic, aesthetic, or
somatosensory stimulation. A partner may be physically restrained in a variety of ways, including the use of rope,
cuffs, bondage tape, or self-adhering bandage.
Bondage itself does not necessarily imply sadomasochism.
Bondage may be used as an end in itself, as in the case of rope bondage and breast bondage. 
It may also be used as a part of sex or in conjunction with other BDSM activities.

Bondage has a very wide spectrum of variations, explore here al kind of Bondage fantasies.
