Mistress CatDeluxe had chose to punish this sissy and she did so using her strapon. The mistress was not concerned about what the guy felt. He was ass fucked by the mistress who did not care what he felt. And when her friends came to visit her, she also let them have a go at the guy. They laughed at him as he cried and that was when he realized that he needed to avoid them.
Mistress CatDeluxe had a friend who was interested in the way in which she humiliated and punished slaves. She asked her to teach her and the mistress agreed. She showed her how to make the slave eat cum and the mistress loved what she saw and what she experienced as the mistress had allowed her to try it. The girl now knew how to go about it and she went home to try it.
This guy was a bully but mistresses Svea, Catdeluxe, Gabriela and Reell had asked him to stop but he ignored them and even felt that he could bully them too. They waited to see if he would change but he did not. And out of anger, the mistresses gave him a beating when he did not. He was kicked, punched and trampled by the angry mistresses and that is when he took them seriously and stopped bullying.
Mistress Cat and her friend felt that they had to torture this guy because he was a wild guy and they did not want that in a guy who was working for them and handling a delicate project. They wanted someone dependable and so they used blowjob sissy training to deal with him and to make him as malleable and as dependable as they wanted. He had to as the alternative was unthinkable.
