Step Sister Tutor Teaches Biology & Sex Ed to Younger Brother

When my mother remarried half a year ago and introduced me to her stunning new daughter-in-law—Misaki—my attraction was immediate. With final exams looming and Mom requesting tutoring sessions for me to ace my studies; Misaki quickly became my dedicated private tutor. During one intense study session at home with Kanna Misaki by my side, she discovered my extensive collection of pornographic books and videos. Believing these materials were derailing my focus on academics (and perhaps something else!), she decided to confiscate everything! Suddenly deprived of my usual masturbation aids and stimulation sources left him restless and frustrated. Misaki noticed his mounting tension and proactively offered to help him 'release' all that built-up semen—and just like that, our taboo relationship began. Beyond textbook lessons in Chemistry or Math, this step sister is teaching me advanced 'Physiology' right alongside it! Thanks to her expert guidance both in the classroom and in bed, my grades have soared dramatically. Best of all, I now find daily fulfillment through satisfying my intense sexual urges with the woman who tutors me, making every session an education in pleasure.
