Mistress Evgenia was asked by her friend mistress Sandra how to punish a cheating boyfriend. She told her friend it was a cruel affair but she insisted that she wanted to learn. So mistress Evgenia asked her to come with her man and when they arrived, she taught her how to make him a sissy and to fuck him in the ass and to deepthroat him with a strapon. He never cheated again.
Mistress Evgenia does not like to deal with sissies. When she noticed that this guy was one, she knew it was up to her to humiliate him and make sure that he would never do it again. So she used her whip as well as her strapon to dominate him and to make him do what she wanted. He knew that it was worse to be a sissy than to change so he changed.
