Mistress Marlena did not want to deal with a rude guy. She was fed up with the guy's rudeness and since he did not want to change, she felt that she had to punish him for it and she had to torture him for it too. He was made to lick her asshole and he had to drink her urine too while her friend recorded what she did to the guy.
Mistress Marlena found out that this guy was misbehaving and she did not like it one bit. It was up to her to do what she wanted to him to ensure that he never misbehaved again. So she cruelly used her shit to do it and as the guy ate her shit, he realized that he was never to mess up with her again or piss her off. He did not.
Mistress Marlena felt that this guy was too whiny for her liking. He was a whiny little bitch and she had to stop that habit. She had to ensure that the guy learned never to piss her off again and that he stopped his whining as she did not like it and it made her uncomfortable. He had to eat her shit for him to get how badly he had to change.
Mistress Marlena was done with her boyfriend and she wanted to dump him. That is why she chose to dominate him and to degrade him in a cruel manner. It had to be a lesson that she was sure he had to learn. The mistress forced him to do things he had never imagined he could do such as eating shit and licking her asshole clean. He cried while begging her not to do it but she did.
Mistress Marlena was bored and the only person she could have fun with or rather at the expense of was this guard. She waited for him to end his shift and she invited him back to her place where she had fun turning him into a scat slave. He had thought that he would have fun with her but it ended up being cruel for him and he could not do anything about it.
Mistress Marlena found this guy to be annoying and for that, she had to punish him. She did not care what he felt or what he was going through. All that mattered to her was that she had fun and that is what happened. He cried as he ate her shit but she did not stop or slow down. She went on with her thing until she finished what she was doing.
