Mistress Zita is a machine. She never gets bored, or tired, because the more pain and humilation she causes to her slave, the more energetic and satisfied she feels. Today she fucks her slave with a huge, brutal strapon, while making him repeat terms like "you are the boss, Mistress Zita" or "I loved to be fucked by you". She smiles while pushing her brutal strapon inside his body all the way to the hilt.
