In the dimly lit, close quarters of their rural home, two sisters, Ti and Tou, engage in a forbidden ritual of bouzen santi. Ti, the elder, whispers incantations as Tou, trembling with anticipation, kneels before her. Ti's fingers, slick with spit and Tou's own juices, probe and prepare Tou's virgin pussy. The air thickens with the scent of their arousal and the smell of the gen bwa they've been grinding. Ti's voice rises, commanding Tou to take her offerings, her fingers replaced by the thick, veined length of the piti-men-fon. The room echoes with the wet sounds of Tou's deflowering, her cries of pain and pleasure mingling with Ti's chants.
