@notknow yeah he does the same thing to a few of his other covers on his Digiket store with different characters, not exactly sure what they mean. I also think is nice to see sex involved with vore, one doesn't get to see that too often. Thanks for the nice comment!
@JoeCarrion ohh I see! thanks for the explanation :) he has opened a Digiket store some months ago, hopefully someone could share any of his doujinshis as well: http://www.digiket.com/gachi/worklist/_data/ID=CIR0012438/
