Slave training by the punishment method works and works well it has been used for many centuries.  In the past Masters would simply conquer a village and take the slaves they wanted and train them the way they chose. Since the village conquering has slowed down and the slave markets to buy slaves have pretty much gone away it has come down to slaves who volunteer for it and enjoy it.

     The Master these days has to be careful if the slave has a night of incredible pleasure and goes to work the next day and a co-worker notices a bruise (which most slaves treasure and the bruises act as a reminder of the hot night they just had) and begins to mention it to them they could become unconvinced how much fun it was or the nosy coworker could just call the cops.

     The last thing you need is a domestic violence charge or worse.  So I recommend that you video tape the whole session and the before and after where it shows by talking to her that she is a WILLING participant and does it of her own free will.  Cheap digital video cameras can be had for 100 -300 dollars and are a great investment since you can then spend evenings watching the incredible reruns. Having video evidence of the slave ENJOYING the evening will take the legal pressure off of you and make the watching fun as well.  Most slaves are show offs at heart anyway and love to perform even better for the camera than they would otherwise.

     As you get into groups being able to see others videos will inspire you to greater heights as well and will improve both your performance as a Master and that of your slave.
