Mistress Katja was disappointed by what someone had done at work and she was so angry by it that she was still pissed when she got home. So she had to do something about it so as to calm herself down. That is why she crushed toys and took out her anger on them. It helped her calm down and address the issue the following day without anger in her.
Mistress Katja found some suspect pictures on her husband's phone. It might be nothing, but she decides to punish him just the same. She takes the phone into the shower and then puts on her most painful and violent pair of high heels. First she throws it down and breaks the screen, then she digs the back of her heel into it to make sure there's nothing left but tiny bits of plastic.
