While I do not have a mistress/master, I have submitted myself to my anal desires. I keep my bum shaved smooth and it is always lotioned. My bum has become so smooth that I know no other existance. I have a 1.25 inch diameter plug that I wear daily (my photo is of that plug, yum). I also have a 7 inch/1.5 inch dildo that I play with on my special days. I have trained myself to cum through anal play while I am finding it more and more difficult to cum without something up my bum. This sissy is yearning for more.
