...having one, or all, my girls properly restrained, and enjoying how delightfully they wriggle at the flick of my tongue tip...what's not properly 'Dom' about it?
Done the right way, it can also be a really handy tool in the Dom's kit for punishment...like taking a girl right to the edge, and stopping.
Also, there's times when I use it as a reward, or just for the simple sake of giving them pleasure.
But, they all KNOW that the nastier side of my tongue doesn't deal with words.
