Madame Svea was fed up with how slow her slave and she wanted to either make him faster or to chase him away depending on how he responded to her punishment. The mistress chose to spit on her smelly and dirty feet before making him lick her feet. He did not have a choice but to lick them and it was so humiliating that he did not want to undergo it again. So he changed.
Madame Svea has a spit fetish and she loves to lure guys to her house for some humiliation using it. She is a good looking mistress and it is not easy for her to get guys to come to her house. This guy did and he already had a hard on before anything had happened. But he was shocked when instead of having sex with her, he had to swallow her saliva.
