When I arrived as a tutor, the one who appeared before me was Kurumi-chan, a female elementary school student who still had a childish innocence. I started teaching her, but she couldn't seem to focus at all—her gaze wasn't on the notebook but on me. "Kids my age are becoming adults... and I have a favor to ask you, sensei... ///" Unable to hide her curiosity about sex, this sensitive girl, embarrassed by being left behind by her friends, actually chose me as her partner for sex. "Sensei... please teach me this side too... ///" Kurumi-chan cooed, flipping up her skirt and tempting me with a panty flash. Even the X in the math equations started to look like sex, and I could hardly concentrate on teaching. Her runaway behavior made it impossible to do my job as a tutor, and though I knew it was wrong, I told myself it was for the sake of her studies and reached out for my student's body. Encouraged by her words, "I won't tell anyone, so it'll be our little secret ///," I desperately convinced myself it was for my student's sake and became the partner for this precocious elementary school girl's first sexual experience. Before I knew it, I forgot about work and kept thrusting my hips, completely defeated. I spent the best day ever, toyed with by a female elementary school student.
