Yeah Aabe Kou is the artist name and he did some doujinshi in which in my opinion, is the most realistic (and hot) depiction of the hypno fetish. He started a 3 part comic but only released 2 parts and disappeared for like 10 years lol. Hopefully this means he will finish it...
And yeah they look like nails. I don't mind it. Love it actually haha. Cause it shows how mindless and controlled that guy is to have nails shoved in. I know it's just fantasy so I hope he continues this type of art.
He used to have his own website which is why I asked. I didn't save the site and now forgot what the site was. :) if you can post more of his new art whenever you see it or can show where you got that new pic, that would be great!
