Cadence is living the submissive dream under the thumb of her dominant and loving Master when trouble comes knocking on the door in the form of her seductive step-sister Riley. Riley has a long history of stealing lovers, and she clearly has her eyes set on Ramon. Unaware of the kinky high protocol world of BDSM she has just stepped into, Riley proceeds to offer her perfect little body for fucking and finds herself signing up for some true discipline and a rough anal ravaging she won't soon forget. Hot wax, metal bondage, floggers, canes, cattle prods, nipple clamps, squirting, and serious spankings are but a few tools to be used top unite Cadence and Riley in sisterly submission.
