I was struggling with my poor grades when I met Mion-sensei, a private tutor who rewarded me with erotic treats. Thanks to her, my academic performance gradually improved. But it wasn't just about rewards—she awakened a deep desire in me, a virgin, making me crave sex with her. Gathering courage, I confessed my desire, and she gave me a dreamlike response: "Only if you score 100 on your test." Driven by those words, I studied tirelessly day and night, eventually achieving a perfect score. On the day I reported my results, Mion-sensei said, "You really wanted to have sex with me, didn't you... I'm happy," and passionately kissed me with deep tongue. During my first penetration, I nearly climaxed immediately, but she gently guided me with slow, rhythmic movements, carefully teaching me the pleasure of her pussy. From that moment, I vowed to keep scoring 100 on every test—because I want to make love with her again and again.
