Electra Pure Divine has her slave on his back and she's intent on sitting on his face and cutting off his air supply for as long as she wants. It's completely up to her because she's the one in power and that's the way it's always going to be. Her perfect ass envelops his nose and the only thing he can inhale is the aroma of her anus and she's okay with that.
Mistress Electra needed to ass smother this guy and she did it in a way that she was sure he would not forget. The mistress enjoyed what she did to him and she was sure that by the time she was done with him, he would not forget it and that he would beg her for mercy. He never forgot what she did to him and he never wanted to piss her off again.
Empress Victoria realized that this mechanic was basically useless. He pretended to know what he was doing when in fact he subcontracted the work she gave him and made money out of her when he did not do any work. She was pissed at him and she facesat on him to punish him for the lies that he was good at his work when all he was good at was being a broker.
