Modern day BDSM cinderella in the kitchen

A nasty step mom, two dominant girls and days and days of chores in the kitchen, this modern day Cinderella is waiting for her ball invitation, but it simply isn't coming, she's being used and mistreated by the femdom females and she can't lift a finger to fight them back. First of all, they are three and she is one, and second, she is secretly starting to like being bossed around and treated like a lowest slave, her stepmom knows all kinds of BDSM secrets, from hardcore bondage to ass whipping, and Cinderella has been put through most of them during her training as a kitchen helper. Now she's eager to please and doesn't think about resisting at all, her suit revealing all of her sensitive spots while she works in the kitchen and her girls and step mom giving her a foot to lick or suck on from time to time, just to keep her properly motivated, after all, if she cleans the floors properly the feet she has to lick and suck on will not taste as bad.
