So overall I still enjoy this manga. However I think the over reliance on crazy ecchi moments has taken the story a bit off course. The series has always had crazy fetish moments but they made more sense cause it was mainly in the context of the Akitos goal to shoot the videos for a sex film to show his whole class. There was also more of a focus on Akito and Kaho getting closer. But recently you had the teacher rape and now you have the MC getting close to Kahos sister. It does make for good fanservice but its not really good for the story. Especially if the author never does anything regarding the rape. I get the series can be nuts but it still needs a bit of believablity for it to keep its quality,
