My curiosity gets out of control sometimes and I just can't help myself

So here is another question from lil' ol' me.
Bottom's -Does your favorite implement suddenly turn evil if it's being used for a discipline session rather than a just for fun session ?
Tops- Are you intentionally turning the intensity up a notch or two or three...or is it all in our head that this is a double owwie spanking because we uhmmm..well we sorta kinda earned it ?
