Mistress Contessa appreciates when something is done well. She had to punish her slave when he did things in a haphazard manner. She had to teach him the correct way. And being the perfectionist she was and not having time, she had to do it once. So she tied him to a sort of cross and she rendered him defenseless. After that, she clamped his nipples painfully before ballbusting him. He learned his lesson.
