Does everyone around us realize we're living under a male chastity arrangement?

Last week my wife mentioned that her girlfriends were still talking about how I set the table, made the coffee and served all the wives and husbands, at someone else’s house. She was vague with her answers as to why I was so domesticated. She said that they were a little envious of her for having such a good husband. Little do they know. We are hosting a party next weekend and my wife want to ramp it up so that they all know who wears the pants in our family. I will do all the serving, setup and cleaning. My wife will just tell me things to do throughout the night but not lift a finger to help. She wants me to wear the new bra she is giving me for xmas under a thin shirt. She also wants to leave a Chastity book among the magazines in our guest bathroom. We do know that people read them as they have commented on the types (vanilla) magazines we have there. My wife’s whips and canes are hanging on hooks to the left of my bedroom door if anyone looked that way. So far after 5 years, no one has mentioned anything. We have left out nipple clips, blindfolds and other non extreme sex toys and no one mentions it so we do not know if they see them or not. My guess is that they would not even know what a nipple clip is or what a cane is used for. Any ideas of things that are not very in your face stuff we can do during the party to show my submission without kneeling and calling my wife Mistress?:)
