My slave, Peter, sent me this pic to prove he was doing a decorating job naked. I would not expect anything less from him.
I have instructed him to begin growing the pubic hair, as I think it would be good to see my slave with a natural hairy penis. He is an adult male slave not a child, so a natural looking penis surrounded by hair is what I want from him.
What will mark him out as my slave will be a brand or tattoo to show is such a male. He will also wear a collar and doing so will highlight he is a slave. I will be proud and happy to see my slave in his natural state: naked and in service.
