[ROYD-173] My stepsister taught me both school and sex

A secret sex movie of Kanna Misaki. Half a year ago, my mother remarried, so I had another older sister. From the first time I met her, I was attracted by her beauty. Misaki had just become a full-time teacher. The final exams were coming up, so my mother asked Misaki to tutor me. While tutoring, she discovered my pile of pornographic books and videos. Thinking that they would distract me, she decided to confiscate them all. Without books and videos to masturbate to, I always felt uncomfortable and frustrated. Misaki also knew, and she even proactively wanted to help me “release” all the sperm that had accumulated over the years! And that’s when my wrong relationship with her began. Not only did she teach me subjects in class, but my step-sister also taught me “physiology”. Thanks to that, my grades improved significantly, and I was always happy because I could satisfy my sexual desires every day…
