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.
Mistress Kylie knew how sensitive foot soles are and that is what she used to torture. She knew that torture did not just have to come from beating someone up. It could also be something as simple as tying someone up and tickling his feet and especially the soles of their feet. It was a lot of fun for her as the guy squirmed and tried to break free but could not. He peed his pants.
Goddess Kiffa wanted to dominate her friend and make it both a good and bad thing. A good thing because she was her friend and they did that to each other all the time. Her friend also needed a good laugh. A bad thing because her friend had pissed her off and she was yet to punish her. So she combined the two and gagged her friend and tied her up before she tickled her. The mistress did it until her friend peed herself.
Lady Naomi tied this guy up to make sure she had a freehand in doing whatever she wanted to him. And what she wanted was to tickle him and have fun watching him do his thing. The guy laughed until he cried and then it began to hurt but the mistress still did not stop what she was doing. And it then became torture for him as she did it.
