Lady Scarlet had a new slave and she wanted to find out how good he was at his job. So she asked him to lick her boots and she graded him. He was average in his foot worship and she wanted great. So she told him he had to be careful as she was going to train him and it would be a one time training. He had to sharp as she would not repeat herself.
Lady Scarlet and her friend had a function which they wanted video taped. So they paid this guy to provide coverage and everything went well until the day he brought them the footage and they found out it was poor quality. The angry and pissed mistresses had to foot gag him and punish him for that. And he had to refund them as nothing much could be done about it.
