Madame Ellen wanted to make sure that this guy ate another man's sperm. She did not want him to think that he could get away with what he had done. That is why she chose to do what she felt was the most humiliating thing he could ever get done to him. And he was made to drink another's cum from a used condom. It was very cruel and humiliating.
When she is bored, this mistress loves to do crazy things. Today she had a lot of time on her hands and she had nothing better to do with it. So she summoned her slave and she tried some naughty things on him. She covered her feet with latex and let it sweat a little then she forced the poor guy to lick them. And it was all for fun.
