I, as many a mistress, have seen this happen. A D/s relationship can be as habit forming as alcohol, gambling, drugs, and anything else that fires off endorphines. Unlike those things, we are not things, but cognisant beings and should pay attention to addictive behaviour. Being an ethical domme is more than not paddling the kidneys, it is also keeping the scene in the scene and curbing otherwise self destructive habits. Not only for the safety of the sub, but for the domme herself.

Having said all that, I have been seriously stalked. Twice. For everyone's safety I have very ridged boundaries these days.
