Well, the Japanese company [ensemble] does have a few with a male protagonist going to a all-girl academy. They are more light-hearted without the bullying and family part (the dad in this one reeeeeeeeally pisses me off XD). There is also one by CARAMEL-BOX called 処女はお姉さまに恋してる 2人のエルダー. Sorry if my English is bad, I am not a native speaker.
Let it take control. I promise you, it feels great >:) mwuahahaha
not even going to say anything lol
