Lady Stefanie has big boobs and a lot of guys fall for them all the time. She wanted to use them today to have fun at the expense of this guy and that is why she used them to control him and to tease and turn him on. Once she had turned him on, she was able to get him to do what she wanted which was to get money from him.
Mistress Saida loves to touch herself and to do things to herself. She does it all because it is fun and she has a lot of fun doing it. But that is not the only reason she does it. The mistress also does it because she loves to control people and she also does it to gain favors. She needed something from this guy so she masturbated and touched herself as he watched.
