Madame Svea likes to humiliate using her shoes. She knows she can have them licked and smelled which is a humiliating thing to make someone do. So she had this loser do it and when he was done, she had him do the same to her socks which were sweaty as well as smelly. He could not say no because he knew the minute he did that, he would get a worse punishment. So he did it.
Madame Svea does not like to punish a slave using the same method over and over again. That is why she had to humiliate him using a new method. She read about socks fetish and she tried it on him. She made sure her socks were smelly before she did it. She enjoyed torturing him with her dirty and smelly socks. She had a good laugh about it because of how he reacted to it.
Madame Svea wanted to show her slave what she does to people who disobey her. She took him to the woods and she humiliated him even though he was new and he had not done anything to piss her off. She told him she was sending him a message so that he knew what he was dealing with. She removed her shoes and she stepped on the ground with her smelly socks and she made him lick them.
