Roleplay Experience of Submission and Control

"The Service Game" is a roleplay experience in which one participant
(the submissive) willingly and devotedly fulfills the requests and desires
of another participant (the Mistress). This game revolves around the
Mistress's pleasure and her control over the submissive. An essential
attribute of this game is the collar and leash, symbolizing the level of
submission of the submissive and their dependency on the Mistress.
