Ahhh, but do not neglect the significance of the deliciousness found in an interaction that follows along the path of:
“Yes, subbie, I know what you wanted. *pet, pet* But I am telling you now *snaps your fingers* that the other one is the one you are getting.” <~ a really yummy way to be directed into your submissive side – to feel it a little deeper… IMHO.

The value of knowing the truthful wants, wishes and desires of your sub are evident in the above interaction. Perhaps if he saw the value… he would be more motivated to comply. (Not that I would ever doubt your sub’s desires to please you, mind.) Just saying, that perhaps he hasn’t noticed the delicious treat awaiting his (hard to work out) honesty.
