Lady Dark Angel had sex with this guy and she was disappointed at the way in which he acted. She did not want him to disappoint another woman so she humiliated him to make sure things changed. So she whipped him cruelly and made sure that he felt the pain and humiliation of what he had done or rather not done. He went and learned how to please a woman so that he did not have to suffer that shame and pain again.
Lady Dark Angel wanted to find out how this guy handled pain. She was interested in a guy who had a high pain threshold and that is why she had him undress and then whipped him while he held a cup with tea in it. She wanted to see if he would spill the tea after she whipped him. She was shocked when she lashed out at him but he did not spill it.
