I use it to prepare her for first meetings and to teach her to be sincerely. Nothing like hearing her change from I have to sound like I am begging to actually begging.

Once you have made her beg to cum even in masturbation till she can't cum without permission then you are well on your way to truly owning her. Anyone that has heard the urgency in her voice knows when to say cum for wench cum hard for cum loud for me cum now. The sounds and orgasmic spasms she goes through when allow are wonderful.
