Two sisters, haunted by religious guilt, find themselves alone with their stepbrother. His massive cock tents his pants, drawing their eyes like moths to a flame. They fall to their knees, their hands trembling as they undress him. The first sister takes him into her mouth, her eyes closed as she sucks. The second sister watches, her hand between her legs, rubbing herself as she waits for her turn. Their lust is all-consuming, their shame temporarily forgotten as they worship their stepbrother's cock.
