Yes I agree it is very good to mix things up from time to time.

Not everyone desires to be controlled in such a manner as mentioned in the above posts.

I don't recomend "cum training" for all as it does require a certian degree of constant comitment, nor do I recomend edge play constantly as it's application with too much frequency lowers a girls heat in some regards.

Each slave is different, the individual training of every slave is allways a challenging and rewarding effort.

It takes ingenuity and disipline to seek out and bring forth thier highest potentials.
