Mistress Gina wanted to show that things will not be the same. This guy thought she was a weakling and liked making fun of her. She is a restrained mistress and that is why she never responded. But he became too much and she wanted to respond once and for all and shut him up for good. So she pounced on him relaxing in his house and made him eat her shit. That did the trick.
I am at home brainstorming what to do with you. You pissed me off but you have no idea. When you come home, you realize I'm mad and as you ask what is wrong, I make you lie down. I then make you open your mouth as I shit into it and make you eat it. You are disgusted but I make sure that you eat and swallow every bit of it.
I was bored in the house today and luckily my slave messed up. I took advantage to make him pay for it and to have fun and kill boredom. I wanted it to be an experience like no other so I got naked and told him to lie down. He couldn't anticipate what was next. I made him lick my ass as I farted into his mouth and told him to inhale my farts.
If you want to brutally humiliate and punish a slave or anyone else for that matter, you just need to borrow a page from this mistress' play book. She knows how to do it in style and you will be inspired by what she does to her slave for not following her instructions. She tied up the slave and then turned him into her human toilet. She shit into his mouth and the poor guy had to eat all that shit.
