The time has come for Step-Daddy to share the gullible girl with Step-Uncle who turns out not only to be some sort of twin to Step-Daddy but just as perverse and twisted. Meanwhile the Step-Daughter proved not to be quite so stupid and rumbled their dastardly rouse to share her inappropriately younger self between the pair as if it was all some kind of fucking game. Turns out all the subterfuge wasn't really needed as the all the little cock happy slut cared about that was that Step-Mammy didn't find out and everyone got away with everything and lived happily ever after.
