There are clips up of dommes doing mild burning or scorching of a guy's butt, cock, balls or other parts using a lighter, cigarettes, candle wax, violet wand, etc and some fraction of them are of a domme in a toilet session burning a guy's pubic hair, etc.

Does anyone here do that to guys in some toil sessions? Or, if so, have any of you who are subs received that? Obviously, this seems abnormally extreme, but also, it seems a way to enforce harsh motivation on a guy. It seems it would be quite bad for some guys who are crying or wanting to back out or complain about their toil session.
