1.COVER: The hentai's first page consisted of character models and description of each of the characters involved and I think that the main protagonist was blonde. It consisted of 4 main girls, 1st girl = best friend, 2nd = club president, 3rd= vice president, 4th= secretary I believe
2.DESCRIPTION: he met his best friend in middle school who was going to go to a high school that just recently changed to a boy and girl school. He is in love with his best friend and is a reason why he also wanted to follow her. His best friend joined that specific high school because of the student council president or the disciplinary club president I'm unsure of which she belonged to. What happens next is the main protagonist and his best friend are elected to represent the class for the school committee and there, they finally meet the president (the girl I was talking about before), in the meeting they talk about male+female relationships if it should be allowed or not. When the president says its forbidden he freaks out because that's the only reason why he joined the school, is to be with his best friend. What happens after the meeting is the main protagonist talks to the president about the changes of the school being male accommodated and when they arrive at the presidents club room the last 2 girls who are part of the club all jump on him explaining that they never had a guy before and all they did was do lesbian stuff with each other and exclaiming that he needed to be kept in check since he's full of male hormones (they only say this because they actually want to just use him as a sex toy). I could go on about the whole manga more, but ill just keep it short at the end the president sees that he loves his best friend and she decides to "promote" him by letting him quit the club and letting him be with his best friend because she allowed male+female relationship on campus.
3.TAGS: The tags I cant find but can probably conclude to were: school life, romance, 3 way (MFF), femdom?, lesbian (1 of the girls likes other girls and kisses 1 in fact, but still has sex with main character),
Sorry about putting a long description, I do remember the whole story just want to find the manga itself to bookmark and read it at anytime. Message me if you want more details about the manga I have every scene description memorized. Thank you!
Given some more thinking it could be with a collection of short stories but having this story I explained as the main plotline
