Lady Stefanie was told to punish and control this cheating guy because he was a serial cheater and she did it because she did not want him to continue to be a source of hurt and pain to others especially those who loved him. She got him to wear a chastity device and she gave his girlfriend the chastity key so that she could control how he used his dick.
Lady Stefanie and her friend did not like how obsessed with masturbation their slave was. They had to do something to make sure he stopped. So they made him wear the chastity device. He had to wear the dick lock and when he did for the first time, they teased him to make it hurt. They also whipped his dick while he wore the penis lock. They then hid the chastity key and let him stay with it for a while knowing well he could not jerk off.
Lady Stefanie knew this guy was horny and wanted to fuck her. She did not want to fuck him but she wanted something from him. She did her best to tease him and make him even hornier. She also facesat on him and got him to believe that she was being kinky. She then gave him jerk off instructions and she got him to cum without fucking him. She then had him give her what she wanted.
Lady Stefanie had warned her boyfriend against watching porn because it is what leads to his excessive masturbation. She chose to make him wear a dick lock and let him go on watching porn. She hid the chastity key and enjoyed watching how he struggled to jerk off but could not. She loved how porn became meaningless to him now that he could not wax his carrot. She managed to get him out of that habit.
Lady Stefanie had a new slave and she wanted to welcome him to her house. She wanted him to understand there was no room for bullshit in her house. So she made him a fine cocktail of her pee. She made it while he watched and she handed it to him and made sure he drank it all. She had fun watching him drink it and she laughed as he struggled to drink it.
Lady Stefanie is a cruel girl. When this guy messed with her, she immediately undressed him and she forced him to wear a chastity device. He expected her to do something different to him but she instead tortured him with the device. She then teased him and got him to have a hard-on. The device was tight on his dick and he felt pain as he got the hard-on. But that is what she wanted and she did not bother using the chastity key to open it.
