I can't read Japanese so I'll admit that I'm not completely sure what's going on. But I can follow the pictures well enough and this seems to be the best One Piece doujin to come out in a while.
I like that it features both pre-Time Skip and post-Time Skip Nami. I like how it looks as though I could easily plug this into the Punk Hazard storyline. I like how the male characters aren't generic faceless guys. I know most people here aren't looking for plot in their porn but I'd say that this is a major step up from all of those Acid-Head doujin where Nami (and Robin) are sluts and screw a bunch of generic guys for no reason.
