Lady Sara and mistress Luna were bored out of their freaking minds and they wanted to find a way to deal with the boredom. That is why the mistresses chose to use their shoes to crush a mirror as well as other items out of fun. And it ended up being more fun than they had anticipated they would have at the start of it all. And thus their crush fetish was born.
Mistress Luna does not care about Christmas decorations. She was feeling lazy and she did not want to go out to buy anything. She chose to look for something to crush for fun and she found out that she had some Christmas decorations. So she used them to crush and she had fun doing it although she created a huge mess in the process but she let her slave take care of it.
Mistress Luna loves to crush with high heels. But today she wanted to try something else. The mistress wanted to use sneakers because they were comfortable. But she needed to know that they were as effective to crush toys and other things as her high heels were. She was glad that they were nearly as good even though not quite as good as her high heels were in crushing certain things. But they crushed toy cars alright.
Mistress Luna was bored at home so she went to her farm and she harvested one watermelon and she crushed it instead of eating it. She was wearing her gumboots and she used them to crush and dominate the slave. She was not doing it to a person but it was a lot of fun and made her feel like she was crushing a loser like she loved to do.
