In a house of God, two sisters find themselves entangled in a web of sin and desire. As they practice their hymns, their fingers brush, igniting a spark that grows into an inferno of lust. They explore each other's bodies, their innocence replaced with a hunger for more. Their father, a man of the cloth, hears their whispered sighs, his own desires stirring as he watches them. He joins them, his massive cock pushing into their tight, untouched pussies, their cries of pain and pleasure echoing through the house as they're corrupted by their own flesh and blood.
