How about a session of intense degradation under the yoke of two sadistic mistresses, as sensual as they are ruthless? And suppose you don't even know who one of them is? That's the perverse game I'm proposing.
I'm joining forces with a beautiful, elegant mistress whose name I won't mention, but whose reputation is well established. I'll call her "Mistress Mystery". The highlight of this session will be to teach you how to be a perfect WC, or to evaluate your skills if you're already experienced in this field.
Of course, I won't be sharing any photos with this mistress, otherwise you'd immediately guess who she is.

Explanations
Mistress Mystery will be in another room when you arrive. I'll receive you alone, you'll undress, I'll blindfold you, and the session will begin with Mistress Mystery joining us.
During the session, you'll have three chances to identify Mistress Mystery. If you find out who she is, we'll remove your blindfold. If you don't, you'll leave without knowing who you've used as a toilet besides me. Amusing, isn't it?
Of course, there will be many other games during the session, depending on what you have entered in the my BDSM questionnaire. But we want toilet training to be on the program, because it's fun for both of us.
There'll be a compulsory game: on a regular basis, you'll have to sniff our panties, and taste our champagne and caviar. Each time, you'll have to guess whether it belongs to Divine Jasmine or Mistress Mystery. If you can't figure it out, we'll know how to punish you...

Such a sadistic and humiliating game... but an excellent idea
