I try never to use as a punishment something that we both enjoy. I don't want my submissive to equate spankings with bad things. Instead, I usually use positive reinforcement to encourage the behavior I want and taking my attention away to discourage behavior I don't want. Ordering her to sit in the corner for a while or having her kneel naked on the floor writing lines is usually all I need to do to ensure that she doesn't disobey again. Fucking her senseless after she completes all her tasks is normally enough to guarantee further compliance.

I do encourage her bratty behavior, though, for play punishment but that's not the same thing.
