As a dom, it always pleases me to see my pet reinforce her submissiveness, and display how happy and content that her place as my slave makes her. I particularly love the spontaneous gestures she makes to show it- the way she hides her face against my chest to seek protection when she's nervous or overwhelmed, the way she nuzzles against my hand and kisses them whenever they come near her, the way she can't help but call me Master even in vanilla public settings. The list of little things she does is almost endless, and each one is a joy to me.
The question I have for you other doms and dommes is: do you enjoy similar things? What little ways do your subbies have to show their respect and admiration? Or are you at the opposite side of things- do you like your subs to only show their respect on command, or in ways you authorise? If so, what do you do? Do you ever let your subs use their initiative, or is everything strictly by command?
