Lady Milana did not like how this slave acted. He was unruly and she did not want to deal with such a person. That is why she had to dominate him and teach him a lesson he had never been taught before. The mistress took him to the woods where she trampled him painfully while whipping him at the same time. That is how he learned his lesson and never messed up again.
Lady Milana wanted to send a message that she knew would be hard to ignore. So she stripped this guy naked and she trampled his balls and his dick. She made it painful as she did it with her high heels. He screamed but they were in the woods and she knew no one would hear him. She warned him that he had to toe the line or get the same treatment again.
