This cock seemed out of the ordinary. I had already sucked two other cocks, those of the two delivery men who I was offered to by Mistress Michelle. But this was another caliber of cock. I licked my lips and slowly apprehended this mysterious cock. I can not describe the troubled desire that struck me at that moment, squatting in the toilet, [dressed like a slut](http://shop.femdoming.com/sexy_clothes/kitten_wet_look_wrap_top_and_shorts_o-s.html) ready to fuck, chained to the pipes by my student dominatrixes involved in this perverse [femdom lifestyle](http://femdoming.com/fiction/femdom-student/femdom-student-submissive-professor-24/). I wanted to give pleasure to this cock that was offered to me and my Mistress did not fail to notice this, “I saw your video, you have made good progress, I’m impressed. You’ve become a real pro at sucking dick!”
Christy.. That’s the voice I recognized. My Mistress, or rather my Mistresses, not the voice of one of my dominatrix students that were in the bathroom before. The fact that Christy is here dominating me, and especially knowing that I knew she knew who I really was, was especially humiliating. Her words pierced my soul and brought tears to my eyes.
