Lady Scarlet and her friend lady Selly felt that they had to try slap fetish. They did not want to slap each other because they knew that it could be a cruel thing for them and so they chose to try and find someone to do it to. So they lured this guy who thought he was going to have a threesome with them. But he ended up being tied up and slapped cruelly.
Mistress Gaia and her friend had boyfriends who were also friends. And when they realized they faced similar issues in their relationships, they went and taught themselves about slap fetish and they used that to torture as well as dominate their men when they messed with them again. They planned it and did it together at the same time so as to humiliate them and make sure it never happened again.
Lady Scarlet did not like how much this old man lied and she had to do something about the way he lied. So she chose to punish him by slapping the shit out of him. He was in a lot of pain as she sat on his chest and slapped the crap out of him. He cried and begged for mercy but she told him he had brought it all upon himself by being a lying bastard.
