a yaoi where
a guy accidentally witnesses his classmate masturbating to the face of his sleeping teacher.
I think they both have a crush on the teacher and the mastubator is afraid of being found out so he swears the first guy to secrecy...and also threatens him to stay away from sensei.

this guy then ends up all sorts of crazy and i think he pretty much rapes the first guy.

somehow they end up together

oh, yea
you find out later that the teacher guy wasn't even asleep.

It's If You Hate Me So.

YES!!
thank you a bunch!!
