Hana and Tetsuya became siblings when their parents married. Feeling lonely after Tetsuya put up walls between them, Hana suggested playing doctor to reminisce about old times. She was surprised to see Tetsuya's big cock. Intrigued, she proposed playing doctor again and let Tetsuya touch her huge tits. From that day forward, she became a plaything for her stepbrother's insatiable sexual desires.
