Markings:Implants

Implants are another way of taking control of the slave, marking his as yours. Its more common of the slaves desire to be modified by his Master expressed in the over all 'mould me' feeling that slaves have. This is also coupled with the feelings that the Master often has of wanting to irrevocably mark HIS property in a never ending level of detail. This seems like a never ending level of control, like when will it be good enough - and the truth is never.  It is easier with puppies cos you just have his collar and for a Owner he has the model of a real life dog to work to. I know my pup has his collar on 24/7, but he gets used to the weight of it so looks for a heavier one so he notices it more - then in time he will get used to that one as well.
With other guys the ownership things as less consensus guide lines. One Master I know wants to cut his slaves cock, slit his urethra other slaves think about having their balls cut out and having either nothing or Steel ones in their place. 

There is for sure something about having MASTER close to you all the time  - his continued presence
