When she comes home from work, she strips down to her panties and calls her slave to her. She tells him to lay on the bed and she sits on his face. She wants him to smell her unwashed pussy and ass. She knows that she is smelling rank because she hasn't washed since the day before. She wants him to feel her pain and and enjoy her unwashed body because when she gets out of the shower, he will go into his cage.
When Lady Cathy decides to punish her slave, she does it while sitting on her ass. She calls him to her and makes him kiss the heel of her boot. She then tells him take her boots off and lay on the floor. She is happy to put her stinky socks in his face, cutting off his breath. When its time for the rest of his punishment, she is happy to take her socks off and press her horrible smelling feet into his face and make him lick the sweat off.
When Luna gets a slave that won't obey her, she has to punish him. She sits down on his chest with all her weight but that doesn't seem to phase him. She is not happy about that. Rather than stop punishing him, she is happy to call her friend BigmommaKat and they sit on him together. That makes a difference. They love hearing him wheeze and struggle for breath. That is how a punishment should sound.
