Mistress Gaia was in the mood to torture someone and she managed to get this loser to torture. She undressed him and tied a leash to his neck and forced him to lick her shoes and do all the crazy things she asked him to do. The slave was afraid and did all she had asked him to do. He did them because he feared the mistress would do worse if he did not do as she said.
Mistress Gaia did not have anywhere to go which meant she had all the time to humiliate her slave. She took him to her dungeon and she tortured him there. She whipped him as he licked her boots and heels. She tortured him and humiliated him and even gagged him so that even if he cried, no one would hear his cries. The punishment was worse because she had all the time in the world.
Mistress Gaia knows and her friend were inducting a new member to their group. She had satisfied all the requirements to join their group but there remained one step between her and membership. The mistresses humiliated him and made him lick and smell their sweaty and smelly feet and wanted to see how she would react. She braved it all and impressed them. She was given her membership on the spot.
