Real Greek master interested in real slave(s) for either limited or long time (24/7) period. 

Be real and ready to serve as I want and not as you phantasize it! 

I am a hard sadist and very demanding.

Iwant  a real slave. Except for sex, slaves must be useful in many other ways. You will be used for outdoors hard manual labor, domestic works, as beast of burden and any other ways.
