How should I treat my slave?

[thir]

Hi there - I am relatively new to the dom/sub world. I am an escort, and have acquired a slave who wishes to fulfil my every desire and for me to be his mistress.
His previous mistress has had to give him up due to ill health, so now I am looking for help please.
How do I use him? train himto do what I want, not what his previous mistress wanted, determine the boundaries????

any help please!!

Is he live in or does he come now and then? What are the limits and bounderies?
