Mistress Marta wanted to carry out an experiment. She had sweaty armpits and nice tits. She was also wearing sexy lingerie and she knew that she looked hot and inviting. And it was in that state that she teased this guy who was so into her and was so turned on that he did not seem to notice that she had sweaty armpits. And she had him lick them after she lied to him that having her armpits licked turned her on more than anything else.
