There isn't a lot of hentai which doesn't feature anime chicks with outrageously huge tits (hey this is the fantasy world after - no need for realism) but Titanime is more like a large collection of good hardcore hentai.
The tits are great but the main attraction is the hardcore - no blurry pixels over the pussies and no unsatisfying anime stripteases. Just gorgeous animated people fucking their brains out.
The big emphasis is the animated side of things - no pictures, just movies and the more hardcore the better. You can choose from 247 downloadable full-length skin-flicks. The vid quality is excellent across the board and the animated action covers everything from oral, anal, good old-fashioned pussy pounding and the occasional group anime orgy. It's a toon fuckfest and you got an invite.
It should be noted that none of this stuff is exclusive or originally produced for this site so there's a pretty high chance that you'll come across this material again and again as you go through the hentai world.
The site regularly updates, so the porno video library will continue to get new titles -it's just too bad that none of these titles are unique to the site.
The subscription costs aren't outrageous and given the amount of downloadable movies that you get the price of admission is definitely justified. On the other hand if you want pics or bonus content there really isn't very much that the site can do for you.
It's a good site and if you're looking for a good collection of high-res hentai movies you'll probably be happy with the low cost of admission. The site's a little skimpy when it comes to additional content and non-movie material however.
