The best way for any spanking to start out is for your submissive to get on her knees and present the instrument to be used on her naked bottom.
I don't know how many times I've had to spank a naughty wife just because it takes her so long to get dressed.
Spanking your naughty wife, or sub, is never ending. They will always need it and they will always deserve it.
Training a sassy young sub who isn't fully into paying attention, giving head, the way she should is always something you have to keep up on. If you don't then after awhile she gets it into her head that it's not important.
