Madame Marissa hates repeating herself. When she got tired of doing that to her slave, she took him for a drive and once she had parked, she turned him into a tiny man and she had fun crushing him and torturing him. She knew he would not do anything about it but would be visibly shaken and would not do anything to mess with her ever again. And it was true.
This giantess was pissed at this bitch and she had to teach her a lesson. She used her powers to transform her into a tiny thing and humiliated her. She shrunk her into a doll and she sat on her using her sexy butt. She suffocated her and made her smell her ass even as she felt crushed. When she was done, she transformed her back to her normal self and left her shaken.
