If you are a domme, what are some thing you do with or to guys without being asked specifically for them, if any?

Consider . . . age play and playing as if younger . . . restraining a guy . . . pegging . . . strap on to mouth . . . breath play & smothering . . . GS . . . inducing vomiting . . . toe or thumb restraints . . . electro shock punishments . . . blindfolding . . . whipping a guy past a safeword . . . stepping on a guy's foot . . . using panties as a gag or using dirty panties as a gag to keep the guy more silent . . . etc.

Some mistresses do some of these things without being asked and some mistresses are much more cautious and do them or most of them only if asked or the activity is invited in some way. Some are in the middle and they introduce unexpected things but only after getting some degree of consent or agreement to the activity.

Other mistresses wait till session 2 or 3 or 4 and start introducing surprise things, but do not do so in the first 1 to 3 sessions.

What things do you introduce or do, even if not asked beforehand? Was it good or bad in results? Have you lost many, if any, subs from a surprise activity? Have you gained or won the appreciation or loyalty of subs from a surprise activity?

If a sub, what surprises has a mistress created for you in a scene or session?
