Everyone else: NO NO NO !!
Me and fellow men and women of culture: YES YES YES !!!
Anyway, I dont think it's a vomit fetish manga, the girls are just Sadist and Masochist, so a perfect pair, it will only get better (and wilder) from here on.
The pacing isn't odd, it is just way quicker than any yuri series out there, Every chapter oozes with progress and it looks like this series ain't no yuri bait too, great manga.
This manga does not give me vibes that Meguro would go back on her development, though I have absoulute faith, both she and MC will have to deal with Exes, imouto and sensei in the future.
That Imouto is there just to bait everyone, you too would be a little sour if your older sister kept bringing home different guy each month. Mangaka just exaggerated that aspect to present a hurdle, the couple from this romance story needs to overcome/adress.
Japan is obsessed with purity way...
