Mistress Amirah is not the kind of person to let someone mess around and get away with it. This guy had been misbehaving and she had to torture and to dominate him. That is what she did to the guy and she taught him a lesson that no one had ever taught him before. The mistress kicked him in the balls and she also spat on him as well as slapped him.
Lady Scarlet was pissed when her boyfriend missed her party. She had hosted the party to celebrate her success but her man did not attend it and did not support her in hosting it. This pissed her off to the extent that she had to punish him and he had to learn to get his priorities right. That is why she ballbusted him and she even let her friend mistress Gaia have a go at him.
