One of any good Dom/Dommes hard and fast rules is to never ever bind and gag a sub, or leave a sub in any way that they can't escape the bindings, unless they are near by to monitor the submissive at all times. Master taught me this at the very beginning of our union. Either this was some newbie BDSM play gone horribly wrong., or it was in fact intentional murder Very. very sad. Imagine the horror this man felt as he lay dying with no one to come and save him....
