In the hushed sanctity of their family home, two naive sisters are drawn into a dark ritual of verification, their father's twisted command echoing in their minds. Forced to strip bare, they stand before him, their bodies trembling with fear and inexperience. Their fingers trace tentative paths over their untouched pussies, their moans of discomfort filling the room. The father, a lecherous predator, watches, his eyes gleaming with perverse pleasure as the sisters, bound by blood and sin, perform their taboo dance of innocence and defilement.
