Being my slave isn't just about being on the ground, shining me up and looking pretty. You've got to be able to take a good whipping too." These are the words of guest Mistress Isabella Sinclaire. As Britney strives to earn her place as rubber maid to her dungeon, her next test is to see just how much pain she can handle. Britney is cuffed to a spanking horse as her rubber panties are pulled up and her ass is given a long and intense flogging while being verbally humiliated until her ass is a deep shade of red.
