A site very similar to
Danbooru, only somehwat less crappy, in that you dont need to sign up and pay to
fap to the contents. It features user-uploaded
hentai images.
I, unfortunatly, know little more about it, because I dont really contribute. I usually only go there to
mooch off of the impressive supply of
Lolicon.
Person A: I'm getting bored with my hentai stash. I need some new stuff.
Person B: Have you tried Gelbooru?
