I call him Master when i know for a fact that i have fucked up big time....and when at home ....it is usually by his name....or Baby....and it depends on the mood or tone of play...what i call him....and i have learned that when i say he is a sadistic bastard from Hell....his reply back is always one of two things...."Then I am doing my job right".....or...."i haven't even really began yet.....*grumbles*....LOL
