In BDSM, servitude is performing tasks and following orders as an aspect of being submissive.

Some submissives gain pleasure and satisfaction from performing services for their dominants, such as serving as a chauffeur, butler, houseboy or maid.

The pleasures of servitude are often combined with the pleasures of fetishes, the pleasures of humiliation or both. A submissive may rub his or her dominant's feet because the sub enjoys providing the service, has a foot fetish or enjoys being "lower" than the dominant, or any combination.
