New position

I wonder if Your Mistress has tried this before. I was at my Mistress's feet while at the ceremony. She were wearing Her black high heels. While giving me instructions about my new status as Her slave, She slipped Her tip of Her heel through my collar ring and then placed it on the floor. Trust me it is a very submissive position, there is no escape. Your face is pressed to the floor. You are at Her feet. Bottom up. If naked, Your balls and ass will be shamelessly exposed. Perfect for dicipline, training or punishment. A very vulnerable position for a slave. Mistress has not named it yet but it is very thoughtful of Her. Mistress said i need to learn my mercy position. I wonder what it would be like !
