I hope potential caners read these comments and ensure they NEVER cane the back. Not only is it excruciatingly painful, but there's a real risk of damaging the kidneys when hitting the lower back. Maybe the punisher in the clip is a novice and unaware of the damage his actions can do, but there's no excuse for not researching the subject before you go out into the BDSM arena.
This is exactly why so many people out there have a low opinion of Bdsm. When you take on a sub etc..... you have a responsibility they have put their trust in you not to chastise/play their bodies in a way that could cause irreversible damage. To me this is not Bdsm yes there are varying forms of it mild to severe but we all know there are do's and dont's this being a definite no no.
