Goddess Celine wanted this guy to stop being a nuisance. She had to scare the shit out of him as she felt that was the best way to do it. She went ahead and she used her giantess powers to dominate him and scare him. The giantess shrunk him into a tiny man and then transformed him back to his former self and he never questioned or disobeyed her ever again.
Madame Marissa found this guy behaving badly and she did not want to let him get away with it. The mistress turned to him and she crushed him with her boots. In no time, he was turned into a tiny man and she tormented him until he agreed that he was not going to behave badly. He even apologized but his apology came a little bit too late as she did not care about it.
