Been meaning to post about this site. I am not affiliated with them, I just own all of their releases.
2d Market offers a small catalog of around 40 doujinshi, translated and uncensored. They're between 2-3€ per chapter depending on the page count and coloring. There's not a lot of community vibe going on on the site, but the release blog and twitter are well maintained.
As it goes with hentai and controversy, the circles they work with are diverse and interesting, so I thought I'd do a rough sketch about (most of) them. It gets darker down the list.
WARNING: if you're looking for SAO doujinshi, be careful what you buy because one of them is not like the others.
Hunt-Hunt is a 37-page ecchi/action/comedy chapter. Fun story, well drawn (pantsu) and full of action and awkward romance. Only non-H chapter.
By Circle
Asaki Blog Branch Office I greatly recommend this comedy chapter about
Marcille getting her clothes burned and having to resort to wearing an outfit they found on a succubus. This circle has quite a few more chapters released. Some are... weird.
Ashitakara Ganbaru chapters tend to get to the hentai on page 1 or 2. Passionate women in welcoming poses, great ahegao here. Hardcore with happy sex.
Kabayakiya has 5 romcom parodies, mostly on SAO.
Dainichakai chapters require a lot of tags. One is a yuri is about a shrine maiden in need of reconstruction funds, the other about a bunny burglar stuck in an iron fence. I can't wait for the next.
Triangle! have 3 color chapters focusing on dominant girls.
Shouwa Saishuu Sensen focus on KanColle parodies. Coersion aplenty, but to me it seems like everyone ends up having a good time.
--------Evil lurks beyond this point.
Muchakai brings 2 short original series (of around 4 chapters) about older men corrupting young girls, as well as 3 doujins on precure & haganai. The most published artist on the site. The art is great and it covers a lot of domination fetishes. I just think old men are a turn-off most of the time. The Haganai parody is probably my favorite.
Fatalpulse.
If the circle name doesn't ring enough, the series is called Victim Girls, and chapter 7,12 and 14 have been released.
Sadistic and morbid, but well written. Degrading and violent, but wickedly well drawn. Confronting stuff that sticks to you for a bit, and something I want to get more of.
Endgame MMO heroines drop epic gear and submit their lives to orcs, a conqueror claims an enemy female captain, followed by a very morbid parody that I haven't read yet.
There's also a story heavy loli one on the blog, but I can't access that on the store page. Title's pretty obvious. Guess it's a cultural thing. Doesn't look like a -very- evil book to me, but I haven't read it, or seen any scans.
So.
If you're feeling like you can never own enough hentai like I do, I hope this helps you if maybe not your wallet.
I pretty much just wanted to write this whole thing to build up to Fatalpulse. :P
