In response to baring a bottom in preparation for a spanking,,,,,,,,,,,,,,,no matter if giving or receiving, stated directly the removal of any & all garments from the waist down is simply the very best method! Personally I do not prefer to direct them to disrobe for I believe the slow and methodical process of removing their clothing and then gently directing them across my lap all "adds" to the overall experience-sharing & intimacy. Spanking is a very age old practice and has been recorded as far back as history is known to exist. This pretty much verifies that bottoms should in fact be bared for a spanking and as to how it is done...............well that is profoundly a personal preference! However,,,,,,,,,,,,,"bared is best!"
