This girl is "Ena." She's my student. It's been three months since we started meeting up after school like this. It started when I was listening to her troubles. I realized that Ena likes older men and also has a masochistic streak, and she seeks the longing for being punished and the pleasure of masochism. One day, when I invited her to a hotel, she came along without hesitation. From there, I've been dick training Ena under the guise of life guidance.
