This doujin is Oogami fucking Hanabi.It starts with Hanabi bound up and being played with by Oogami. He later releases her and fucks her.This is straight sex with a bit of BDSM. The art is good, very good. Of course, like most hentai doujin, there is little to no story here. Overall, I'd say this is a good doujin. Definitely check it out if you're a Hanabi fan.
