You should probably give credit, especially to lancea (first picture ; I'm not sure he'd approve using his comic's drawing in such erotic/porn, too)
I love doujinshi, but that's way too much for my taste... Then again I was never a huge fan of Sisters of mercy. I have truly underground tastes >_>
Then again I don't do slide shows much, apart very specific ones.
I'm sorry I guess we just don't have the same tastes.
