Mistress Dana is a naughty girl and she loves to do naughty things. Today was not an exception for her and she chose to use her ass to do it. But she felt that that was not enough to make it naughty and so she added her boobs to the mix and also used them to crush the plastic cups. It was a lot of fun for the mistress as she did it.
It was not fun for mistress Dana to crush paper cups with her feet because it was easy. She chose to use her boobs to do it and she had fun doing it. She knew her ass was also not suitable as it would crush them easily. So she naughtily settled on doing it with her boob. But she did it with her ass and her foot once to compare the extent of damage.
