My girlfriend's piano teacher, Ms. Kuroshima, is elegant, beautiful, and gentle. With my relationship failing and my girlfriend refusing sex, I ask the far more attractive teacher to give me lessons too. She presses close behind me and guides my hands across the keys. Thinking she looks too kind to reject a forceful advance, I lose control and grope her breasts from behind. “This isn't right…” she protests softly, but her troubled expression only excites me more.
