I've searched multiple sites using every variety of tags I could think of with no luck and even the search feature of these forums came up with no results. Still, I very much remember reading this manga a long time ago and want to try and refind it. Can see it as being popular here.

Name I always knew it as was 'i-hate-my-daddy' or some variation, with the dashes. Tags I know it had was translated to English, it was about a group of loli school friends who wanted to fuck their dads, and the different chapters dealt with them going about things. Can confirm, it is not Scandalous Girls.

Key things I remember:

- First girl was most 'innocent/naive' and kept calling erections as her dad's penis 'getting angry' as she tried drawing it on a chalkboard before class
- the 'snobby' girl was reluctant as her father was the instigator and they screwed in her school uniform
- tomboyish girl (at least with shorter hair)'s chapter centered around creampuffs and she seduced her single father in his manga studio
- first girl finds 'snobby' girl's phone and they become friends
- nerdy girl with glass's mom was the teacher of the girl's teacher and she doesn't know her actual dad, but picked the teacher out of a photo line-up as her choice
- nerdy girl ends up fucking the teacher in the school library during sports day
- manga ends on first girl again drawing a chalkboard dick and talking about 'dicks getting angry' to lolier students and getting in trouble with one of her friends, bookmarking the beginning and end of story

That sound familiar to anyone?
