If you (Master's, Doms, Mistresses, Dommes) were to hold a D/s party / weekend, Would you expect your sub/slave to be host/hostess & what are your expectations of them & what limits would you set for them?
LOL. I'm going to play a bit with the semantics.
Never let the sub host the party. That's your job. The sub serves, services, and/or submits per your wishes.
