Lady Fenja wanted to dominate and humiliate her slave and she did it as she read an instructional book on how to do it. She had the slave do the things she read as she read them and he did not have the time to do anything wrong as she warned him of dire consequences if he did not get it right. The mistress had fun doing it all and knew how to do it without the book next time.
Lady Fenja was pissed by the fact that her boyfriend acted childish. She felt that he had to change especially as such acts and behaviors were hindering him from achieving his full potential. So she used her high heels to trample him and she also used her saliva to dominate him. He became her foot slave for a few days and he learned that she was not messing around and he started to make changes.
