After accidentally stumbling upon his father's stash of adult videos, a naive younger brother becomes terrified of sex. Concerned for his innocence, his sister Hibiki decides to take matters into her own hands, teaching him the truth about intimacy through a series of hands-on, private lessons.




















Her voice is cute and her body is erotic. It's packed with sex appeal and lust, which is super exciting.
*The process in which Hibiki Otsuki gently guides her younger brother into sex, as if she were a caring mother, is carefully and carefully developed, making this a masterpiece among situational works.
*I wish I had an older sister who is as cute and kind as a doll. In the middle part, the older sister cums in her own bedroom. If Hibiki cums in her room, I wonder if this is what it would be like, and I feel a shiver. It's really cute. Mr. Hibiki. I'm a huge fan.
I bought this for Otsuki-san. For some reason, she does a lot of mature-themed works, but she could still easily pull off a high school girl role.
His lower body is incredibly long, I'm jealous. Must be nice to be able to have sex with Hibiki-chan.
