Triangle [English, incest], by Rio Yanagawa & Yamasaki Masato

The incest theme isn’t my cup of tea (mother-incest shocks me a little, sister incest leaves me with a “who cares about that”), but THAT manga is exceptionnally well drawn, realistically, with a real scenario, and the two mangakas (mainly Rio Yanagawa, with a bit of help by Yamasaki Masato) are interesting because they’ve made many other works too. Besides, it’s not a real mother, it’s a stepmother, the moral is safe… or almost, well, there’s still a brother fucking his sister and stepmother together right after a big group of people ganged the stepmother because the sister asked them too, after all ! :3
