Mistress Gaia did not like how this guy disobeyed her. She was so pissed by what he did that she had to punish him and do it cruelly. The mistress ballbusted him because she knew it was very painful and that once she did that to him, he would not mess with her ever again. He was in a lot of pain after what she did to him and he liked her armpits like she wanted.
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.
