Mariko, the innocent daughter of a pious man, is haunted by her carnal urges. She slips away from her chaste life, her heart pounding with each secret step. Her fingers tremble as they push aside her silk garments, revealing her untouched flesh to the cool night air. She gasps, her breath fogging the night as she dares to touch herself, her virgin hole aching for more. But her father's voice, stern and disapproving, echoes in her mind, "You mustn't, Mariko!" Yet, the fire within her burns brighter, driving her to seek out the forbidden fruits of her desires.
