I'd really be curious to see the inside of the doujin. This is actually a really good illustration.

I don't know where to find this doujin, but I can direct you to another doujin by the same circle, Digital Accel Works.

It's from D.A.W., and after some digging, I found out that it's not actually being sold until tomorrow...

Thanks, I guess whatever they find on the new one they'll post it there. Or here. I saw the back cover for the upcoming one, which would be this one.

You have to admit the cover is gorgeous as hell. But the contents are MAN O' MAN!! Bukkake with a side of comedy anyone? 'What happen to the groceries that 'Masane' was sent to the store to buy? Well...y'know it's not everday you get to engage in a orgy with generic EXCONs and Shiori all in the same night.
