Trampling in Mary Jane Shoes - Naked Body

Before recording my usual session, I decided to try some trampling with my poor slave. He is not really into these stuff but as it's my business, my rules, by orders. Ignore the setup or location as it was just for testing... However, that pair of shoes, the Mary Jane ones, are quite painful and probably were not the best choice for a first trampling attempt. You can clearly see how my slave' skin turned red really quick... I have to say, it was fun, but it needs more work. What do you think?
