Service top

Within a BDSM context, a Service Top is a partner who is the active participant, applying the activities or techniques of BDSM "play" upon (a) bottom partner(s), but who does not exercise control or dominance over the situation. The application of such activities may be requested, or even directed, by the bottom partners(s) who have de facto dominance of the context.

Most professional Dominatrices and Masters are considered service tops.

Service tops are considered by many devotees of BDSM to be failing at maintaining a "proper" BDSM relationship dynamic, as the stereotypical archetype of the Top within such communities is typically the Dominant-Top.
