This guy broke into mistress Barbie's house thinking no one was home. But she was there and she did not let him get away. She laid a trap for him and she caught him before she used her shit to deal with him. The mistress made him eat all of her shit and also drink all of her pee before she warned him never to try to break into her house again.
Mistress Barbie was fed up with how slow her slave was. She was the kind of person who wanted things done quickly and she had to teach him that virtue. She did this by making him eat her shit and also lick her asshole clean after she was done shitting on him. He never wanted to experience that again so he changed and it became a motivating factor for him.
Mistress Barbie did not want this guy eating her shit from a bowl or plate. She wanted her shit to be eaten directly from her asshole. And that is what she made this guy to do. He had no choice but to do it. The mistress enjoyed herself at his expense and he regretted why he had pissed her off as now he had to pay a stiff price for it.
