An 18-year-old high school girl named Miku, blessed with an extraordinary natural anal. With straight black hair, a petite slender frame, translucent fair skin, and an adorable smile, she lives next door. Miku confessed to me, an AV director, that she's curious about anal play and begged me to shoot her. Fulfilling her wish, we proceed with her first anal stretching and anal virginity loss. Her innocent, youthful expression gradually drowns in pleasure, beginning to savor ecstasy more than pain. Her pure, untouched anus, captured on camera alongside her increasingly lewd expressions, seems to reflect the transformation within her heart. The contrast between her innocence and her anal awakening captivates every viewer.
