Mistress Marlena wanted to dominate this guy for being noisy and for ignoring her when she asked him to change. The mistress was not going to let the guy get away with it and so she used her shit to dominate as well as to degrade him. He cried and he begged her to stop but she did not. She had him learn his lesson in a humiliating and degrading way.
Mistress Bastienne wanted to make sure this guy had poop all over his body. So she had him lie down and she got on a swing on top of him. She then took a shit as she was swinging back and forth. Each time, the shit landed on a different place and he was asked to eat it. Beyond that, he was also asked to smear it all over his body.
