Yuki is my former student, and I've become involved with her in a relationship that crosses the boundaries of my role as a teacher. She started coming to my room three months ago, after I listened to her talk about her problems. That's when I discovered her true feelings—she's attracted to older men, has masochistic tendencies, and craves the thrill of being dominated and the pleasure of submission. I've begun training her under the name "Disciplinary Training," molding her into my perfect sex slave.
