Taken from Thor-Hammer:
A wild mix of comedy and h-adventures ensues for this strange group of characters, as they set out for adventure. Jammed packed with awesome sex scenes (most are even more intense than those depicted in Slut Girl). Probably Isutoshi’s most personal work. The “H” is very hentai, with lots of group, dp, spoof, and more... but with a good amount of gags/comic relief thrown in as well!
