These mistresses felt that their friend was not being a good person and that she deserved to be punished. So they did it with their tickling fetish and it was a soft way to punish her. She laughed hard and the tickling soon became painful and she had to beg them to stop as she could not do it anymore. They then took that chance to warn her not to do what she had done.
Goddess Harley wanted to torture this guy by tickling him. She did not want to beat him up. She knew that she could achieve what she wanted by torturing the guy with her hands simply by tickling him. That is how she undressed him, tied him up and she tickled his armpits as well as the soles of his feet. The guy peed himself and he nearly shit himself in the process.
