I'm looking for this story I read quite a few years ago. I'm fairly certain it was just one chapter, so it was probably in a collection of stories or included as an extra after the main story of a volume.

It was about a student, I think university ago who was living with his teacher/professor. At the beginning he is trying to seduce the man, I believe, but the teacher is trying not to give in so he gets mad and says he can't take it anymore. The student is shocked and then starts skipping class. The teacher has to rescue him from being raped, I think, when the younger decides to go to a bar and someone tries to drug him.

If anyone knows the name of this, I would really appreciate it if you could tell me.
