For many the spanking and all that comes with it is over once the spanking stops and she's given her hug and cuddle so she knows all is good. However, there are those occasions when I feel it's necessary for her to, shall I say, cool down. Her bottom can still be very warm to the touch and a little humiliation can be good for her. Plus, the more she exposes her body the more she is comfortable with it.
Frankly, my wife will walk around naked when I suggest I would like her to do just that. To my wife, her body is for my pleasure and if that pleases me then she does it without hesitation.
