Houkago: Nureta Seifuku

Another perfect example of why guys should never be to greedy. 

It has the whole Angry sex crazed teacher bit oh and the girls are all sick in there own way 

school girls forced by their teacher, age-gap, 

They both contains main character as a male teacher and like had sex with female students. Both happens at school. Both are hentai. The students were initially blackmailed but then like to have sex. If you liked After class lesson there is a chance that you might like yuuwaku. 

They both involve the students and the teacher, they have similar settings, the characters are similar, both story lines are similar.The teacher character in both of these are very similar, none of the students like him, but there is one student who doesn't mind him, and so the Teacher manipulates the students, and use and abuse them. if you liked one, you will like the other. 

Almost the same story where the student didn't like the teacher at all the fisrt time but then having something like lust to have sex with the teacher...
