BDSM slave is the submissive individual that gives up the power to a dominant person that is known as the master or mistress in a BDSM total power of exchange relationship. It is by far the most loaded or triggered word in the common BDSM vernacular. Before throwing the word around, a person has to educate self so a person has to understand ancient or present trauma around slavery, from the trans-Atlantic slave to person trafficking would be wise. The slave becomes viewed as the Dominant estate, both through the Dominant or the wider BDSM population. All property once owned from car to clothes, usually becomes the dominant property. However, this is different from slavery, as this is pertained to in a wide context, that the sub has willingly relinquished the freedom, which is the main difference, the essence of which cannot be overstated.

The BDSM slave is credible for a committee of each dominant partner required or wants. Also, attend the sexual needs, prepares the food, house clean, or provide emotional supports and company. The slave is often entirely subservient to the dominant partners. Also can ask permission before doing anything or be available for whatever the Dominant request. Slaves also have to complete the daily housework or hard work for dominant approval. Slaves are often subject to punishment if deviate from the responsibility. Slaves may also receive rewards for good work, such as finish all work for a day or maintenance of good behaviour for an extended duration.
