Squirt shower for my slave slut

I recently got Helen as my personal slave. As her mistress, I now have total control over this little submissive slut... Right in the morning after waking up, there are important things to do. I get into my extra hot mistress heels, and then off to the bathroom, so that the slave slut can empty herself. But not on the toilet, just in the shower. It is still visibly unpleasant for her to piss in the shower in front of me, but she will have to get used to it. I have also already taught her, that she will no longer drink water from a glass, but must lick it from a bowl. Today she learns from her mistress that a morning shower can be quite different than before. She is allowed to lick and tease my legs wrapped in nylons, while I work with a glass toy on my horny cunt. Finally, I get my orgasm and she an extensive squirt shower...
