Mistress Sarah likes to crush and she had crushed almost everything in her house. She wanted to crush something she had not crushed before so she crushed plastic cups. She arranged them neatly then she sat on them. She crushed them with her butt and she instantly deformed them. They could not be used again and she could not crush them any more than she already had so she threw them away.
Princess Serena does not like plastic cups in her house. When she found some in her house, she was pissed as she knew it was her slave who had bought them. She did not want them to be in her house so she crushed them using her high heels. She destroyed them and she left a mess in the house. She told her slave to clean it and never buy plastic cups in her house again.
Gina and Lady B do not give a damn how majestic something is. These two women are sexy mistresses and they will punish whatever they want to punish. Just because this is a poor defenseless unicorn doesn't mean that it can escape the abuse. These two women punish and humiliate this poor animal by crushing it with their big asses. They pull all of their weight on its back, riding it.
