From what I gathered he didn't sleep with the teacher. The teacher didn't want to sleep with him. He felt troubled that his student was wearing woman's clothing and he mistook the teacher's worry and kindness as him finding interest in him.
I believe that the student jumped him and they got caught and it looked like the teacher was taking advantage of him and he lost his job because of that. The student kept sending him pictures of him doing stuff and wearing woman's clothes and the teacher felt disgusted and disturbed and went to confront him because he wanted it to stop.
I have NO sympathy for the Sensei. It pissed me off, blaming the student for losing his job. Hey asshole, you didn't have to fuck the student. You could have been firm and said no. No one made you stick your dick in him. Yeah, I feel bad that they got caught, but you can't lay that shit on the student.
