Mistress Gaia did not want to inflict pain on this loser. She wanted to try a different kind of punishment. She had used pain too much and she did not want to use it again. So she waited until her slave pissed her and she tried armpit femdom. Her slave had no choice but to lick her armpits which were sweaty for that purpose. He also had to sniff and smell them.
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.
