Alas(???), the sequel already exists and it's NicoMakiNico.
It will be interesting to see how Tomo somehow makes Maki the top in that scenario.
Seems like Ooshima Tomo has run out of ideas for new mangas and just draws porn for fun.
Not that I'm complaining or something.
And yet, they drew NicoMaki Sun! (and sequel!), an idea just dripping with NicoMaki lewdness... and it was (technically) SFW. At least we have every other doujin in their catalogue.
