Miss M. - maybe the M stands for Merciless? This was for sure the feeling slave Presley had in this scene, as he was screaming like if he was going to, more or less from the second Miss Ms sharp heels hit his slave skin. Miss M. is very merciless and as slave Presley always says he can take extreme trampling, she really wanted to break him down! Miss M. was simply tired of all this nonsense from slave Presley about how much trampling that he could take! I don't think this slave will ever ask Miss M. for a hard trampling again...
