In Japan, censorship has made the porn industry a little more creative than they may have been otherwise. Since they can't show cocks and pussies, they created a world of cartoon porn, better known as hentai. At Hentai Toons, you will see their work in action. However, if you have indulged in hardcore cartoon porn in the past, then you may remember that this site's content looks very similar to Hentai Key. There's a very good reason for that.
No, it's not just the fact that all 161 movies found on the landing page when you sign in are taken from nonexclusive DVDs. It's because those 161 movies can all be found on HentaiKey. You see, HentaiToons is known as a "GT site" by that other one, meaning it exists solely as a bonus. Not much of one, either, as this one is very unappealing to look at and navigate through, on top of giving you content that you'll find on the other GT sites and in bonus feeds, anyway.
It even has four links sending you to the main site in order to view the rest of the content, three of which erroneously redirect you to its join page instead of to the homepage. Another issue with these versions of the movies is that they're all DRM-protected downloads, whereas some of the other GT sites that offer the exact same smut aren't.
It's tough to make heads or tails of everything on account of how vast the collection is and because of how many pages link to the same bonus feeds. However, I estimate that there are roughly 25,500 movies and a good 1,300 photo sets. The main site has both original and licensed content, as well as links and sub-sections galore. There are also those GT sites I mentioned, some of which contain more hot anime chicks posing and in hardcore hentai action.
However, most of those GT sites either only add content already found on each other, whereas it looks like those that don't link directly to the bonus feeds instead of have their own proper video sections. It looks like new material stopped being added to the main page 10 months ago, and even then, it was only four images being added to galleries that already exist, so it's actually been around 20 months since the last full update.
The good news is that some of the GT sites add tons of material every month. A few add doujinshi (self-published works) intermixed with all the repeated content, I saw one that adds a new photo every day and there's another site that uploads a bunch of hentai and non-hentai videos every time it updates.
The quality is a little all over the place, but the images are always clear, despite none of them being high-res. Meanwhile, some of the movies offer good-quality playback. Depending where you find them, you can either stream them in Flash or download them in Windows Media format. However, most movies are low in quality.
Besides the tons of vids and pics, there are also games and Flash animations. Those bonus feeds I mentioned earlier also include live-action porn starring some of the biggest names in the industry.
Hentai Toons has some serious issues, but the abundance of smut makes up for them. If you're a hardcore fan of hentai action, then it's worth ignoring the navigational problems and joining up with either this site or the one where it gets its content from.
