Mistress Anita wanted to facesit this guy and she did it to him while he masturbated. The mistress had to ensure that the guy learned to do things the way she wanted and that is why she chose to cruelly facesit him and ask him to jerk off at the same time. She knew it would be hard for him and that is why she asked him to do it.
When this guy misbehaved, he did not know what he had done and how angry he had made these mistresses. He was shocked at what they did to him and he was scared shitless as they trampled him, made him lick their feet and he also had to endure being facesat on and smothered by their asses. He had to smell their asses and lick them as well before they let him go.
