See I told you she'd be punished just like you sissy's. don't worry she can't see you traitors as she is behind one way glass. Her punishment is much harsher than you sissy's and even though she was so nice to you, you have put her in this position. I hope this has taught you not to take advantage if you happen to have a nice mistress or indeed boyfriend as your selfishness could lead to consequences.
Now you may be wondering what we have planned for her. Look at the fear in her eyes, she hasn't been told anything and it's all because you sissy's couldn't resist stroking those clits. Well that machine there is going to fire eggs at her, not only will it be a humiliating experience for her it will also hurt, we will then send her new video around the world and make sure she knows about it. After her humiliation she will spend 6 months locked in a cage in this dungeon before being reinstated as a mistress. You sissy's better work hard and graduate before she returns, as I can't imagine she'd be too forgiving.
Fire the first round.
