Mistress Kylie and mistress Chloe had a good time playing with their feet and their sneakers. They did this because they were bored and had to find a way to pass time. The mistresses did not know what they were doing at first and they just went along with it until they got a rhythm and started to enjoy it. And that was when they discovered that foot fetish was actually a thing.
Mistress Mikaila wanted to torture this loser with her feet. She did not want to inflict pain on him so she chose to do it with her bare feet as well as her socks. She got the loser to lick her socks and smell them before she made him do the same to her bare feet. She has a lot of fun humiliating the loser till she forgot why she was humiliating him in the first place.
