Mistress Caroline did not like how this guy had poor listening skills. She did not want to talk to someone who did not listen because it meant she was wasting her time. The mistress had to punish the guy and she did it with her armpits. She made them sweaty before she asked him to lick them. It was cruel and degrading but it was what he needed to learn a lesson.
This mistress is smoking hot and she knew this guy wanted to have her. So she put him to the test. She is an adventurous mistress and she does not shy away from having fun. All kinds of fun. And that is what she did by trying to have fun sweat. She worked out and was sweaty all over her body. And she got this loser to lick her sweaty body starting wit her armpits.
Mistress Ava was bored with the regular methods she used to punish her slave. She wanted to try something different and she did. The mistress worked out in order to get her body to sweat and it did. She then summoned this loser and she got him to lick her armpits. She told him that was the easiest thing she could make him do. If he did not, she would do something crueler and he did not want that. He licked her sweaty armpits.
