to clarify, there are TWO versions of this manga, made by the same author
one of it is a very eechi borderline hentai manga focus on more plot, the other is straight up hentai
the only mother/daughter yuri is in the hentai version, however the hentai version has some missing chapters and most of them are not translated.>how to you access that nowadays?
same way as always
remove all cookies from exhentai, open e-hentai, log in, type in the exhentai url while you have e-hentai open logged in
after that you can access exhentai everytime normally
