This slave thought he knew it all and he tried to do things his way and not the way madame Marissa had instructed him. He ended up messing and since she had warned him, it was now time to punish him and she made sure the punishment was cruel and that it led him to realize he can never ignore her instructions again. He learned his lesson and they never had issues again.
Madame Marissa spat on her boots and she forced this slave to lick them and to clean them using his tongue. He had no choice but to do what she had ordered him because she had scared the shit out of him and he could not afford to disappoint her as he knew it meant another punishment. The loser never forgot the punishment he got and never messed with her again.
Madame Marissa likes to test her slave from time to time. That way, she gets to know if he is getting better or getting worse. Today she did not like what she saw from him. She punished him by making him smell and nearly choking him with her dirty socks. She spat on them and she had him lick the spit off of the socks before he smelled the socks.
