Goddess Nika did not like how her boyfriend had poor communication skills. She had tried her best to get him to change and she had tried to change with him and to do all she could to help him through the process. But he did not and that made her feel that he did not care. That pissed her off and she had to punish him which she did with her crush fetish.
Mistress Jessica was bored at home and she wanted to find a way to pass time without having to go anywhere or to beat up anyone. That is why she chose to use her crushing fetish to do it. The mistress settled on crushing grapes at home and she did this with her boots. She made a mess on the floor as she did it and then had her slave clean up after her.
Lady Shay was out to dominate and she did it in the way this guy did not expect her to do. She cruelly turned the stuff she was crushing into interesting pieces of art as he cruelly turned them into art and she had fun torturing the loser with her crush fetish. It worked out the way she wanted it to work out and she loved everything about all of it.
