Getting regular spankings, whether you misbehave or not will keep you from getting into trouble. No, I do not believe that and I doubt many others find sense in it either. But we all know spankees just want to be spanked sometimes and it can be hard for them to ask. They should not have to misbehave to get a spanking, especially if they are trying to improve themselves.
So I use maintenance spankings for those I discipline. We set rules for the behavior that is expected. The rules we set up are meant to be obeyed, not to set them up to fail so I have an excuse to spank trhem. We do not want a discipline spanking to be necessary very often, but in most cases we want to get together every so often for some bottom warming fun.
The way the maintenance spankings proceed can vary, depending upon the needs of the spankee. It is going to hurt or it's not a spanking. In most cases, they like the soreness to last a while. While there is not normally the need for a lecture or scolding, she may still need me to be firm and strict. I usually go more with a warm-up and use the implements she likes than the one implement I normally use for punishment.
