One you do it on pants you know that is a real live person, and when on the bare bottom you are in no doubt that you are going to inflict some very painful blows to that bottom, often a young boy under 14. For those who like the idea of fun slippering I have a question.
Do you think you could really slipper a boy, even a fun slippering when you have a boy bending over showing all his bottom, and waiting for you to inflict pain on it. Not only will you hear the pain but see the mark on the bottom when its been hit.
