JUEM-006 - Innocent-looking but daring little sister, Haruna

Haruna, a cute and innocent-looking girl, is at that age where she needs money for everything. After being rejected by her brother for a loan, she starts a secret part-time job that is far more daring than her appearance suggests. One day, after a bad breakup, she vents to her brother, and the mix of loneliness and pent-up desire leads them to cross the forbidden line.
