Trampling Newbie Tormented Under Brutal Boots

This fellow applied to be my slave, but he has never been trampled before. Lets see what hes able to take! Im not going effortless on him obviously - I put on my buffalo boots with chunky, but sharp heels and a deep painful tread. The shoes leave nice marks on his skin with every step and hes struggling to take this punishment for sure - but of course he doesnt want to disappoint me and therefore tries his best to endure whatever Im doing to him!
