It gets real trippy at page 22
Gambler Club's group sex scenes are always amazing. He always makes the girls look like they're devouring each other.
If you go to gamblerclub.jp his homepage and click on this Iris doujin, can someone translate the comments on the very bottom he wrote? Some people were begging him to include Leaf, Hilda and Rosa in PM Gals but he said they won't appear since they were never in the anime.
Someone also asked him to draw Bonnie/Clemont, and he said something like, "I would like to draw them." I don't know if that's a hint to the next PM Gals or not. He's drawn tons of loli before in his other doujins so I wouldn't be surprised if Bonnie gets included at some point.
