Speaking of which, what is the work that introduced you guys to this great genre?
For me it was probably a hentai animation called True Blue, I watched it again recently and even if the animation doesn't really hold up, there is still some moments that have stayed for me since then.
That or this doujin of Detective Conan, which had the added bonus of also including incest.
I'm sure I read or watch other stuff, but these are the ones I remember quite vividly.
